    The invention relates to a mounting frame for a power supply unit for an industrial truck, in particular a counterweight forklift truck, which makes it possible to replace a power supply unit with a transport supply unit in horizontal assembly. is provided with plug-in ducts for fork claws of a load fork of the transport truck, where by inserting the fork-claws of the transport truck into the plug-in ducts of the mounting frame, the mounting frame can be used to change the power supply unit from an assembly space of the industrial truck.
    Industrial trucks with electric drive systems, especially counterbalanced forklifts, have recently often been designed with a lateral change of a power supply unit in the horizontal direction via an opening arranged in the side in the vehicle chassis. In this case, a battery bank, an industry cell unit or a hybrid drive unit can be arranged as the power supply unit. A battery bank consists of a battery charger, which occupies several battery cells. Such an industrial truck with lateral replacement of a power supply unit is, for example, known from DE-A1-102 48 657.
    In the case of industrial trucks with a lateral change of the power supply unit in the horizontal direction, the power supply unit is changed in the horizontal direction perpendicular to the longitudinal axis of the vehicle and thus in the transverse direction of the vehicle of the industrial truck via an lateral opening in the industrial truck's vehicle compartment.
    The handling of the power supply unit during replacement and thus the disassembly from the assembly chamber or the assembly in the assembly space, for example a battery compartment has the industrial truck can take place through an additional transport truck. In this case, a mounting frame is shown, on which the power supply unit is arranged standing. The mounting frame is provided with insertion channels for the rammed fork claws of a load fork of the transport truck. By inserting the forklift claws of the transport truck into the insert channels of the mounting frame, the mounting frame can be handled with the transport truck for replacing the power supply unit when disassembling from the mounting space or when mounting in the industrial truck mounting space. The mounting frame accommodated with fork claws makes it possible to raise or lower and transport the power supply unit present on the mounting frame with the transport truck when disassembling from the mounting space or when mounting in the mounting space.
    During operation of the industrial truck, the mounting frame with the power supply unit present there is arranged in the mounting space of the industrial truck and secured and fixed against unintentional movement, especially against unwanted lateral movement in the transverse direction of the vehicle.
    An undesired lateral movement of the power supply unit and the mounting frame in the mounting space in the transverse direction of the vehicle can occur, for example, d5 accelerations of the vehicle lead to corresponding horizontal lateral movements of the power supply unit or the mounting frame in the mounting space. Such forces can occur in particular when cornering or in collisions, which can occur, for example, when lifting a load or in a collision with an obstacle, especially in a collision with an obstacle with the counterweight of the counterbalanced truck.
    In order to avoid such an undesired lateral movement of the power supply unit and the mounting frame during operation of the industrial truck and in particular an undesired design of the power supply unit and the mounting frame of an industrial truck with lateral replacement of the power supply unit from the side arrangement of the industrial device. which are removably, rotatably or collapsibly arranged at the side of the chassis side of the industrial truck open at the side. As a rule, the safety device is maneuvered by hand and thus manually by an operating person.
    DE-Al-10 2005 007 584 is a forklift truck with a laterally arranged battery change in the horizontal direction, in which at the power supply unit at the mounting space a manually stopping device by a service person as a securing device is arranged between a stop bearing and the working bearing, which is arranged within a working area within a mounting surface of the mounting chamber and cooperates with the lower edge of the power supply unit. The layer of the welding device is monitored with a sensor device. In such a stopping device, however, the monitoring of the stop of the stopping device with a sensor device is very disturbing. Furthermore, the sensor device increases the manufacturing cost. DE-Al-10 2007 028 862 is an industrial truck with a lateral battery change, in which at the side surface of the industrial truck mounting chamber as a locking device a laser arm which is manually rotatable by a service person is arranged, which cooperates with the power supply unit. DE-Al-10 2008 034 782 describes an industrial truck with a laterally arranged battery change, in which an angularly shaped hall plate rotatably angled by an operating person between a mounted bearing and a disassembly layer is manually arranged by an operating person and arranged as a locking device for an upper side area of the industrial truck. the power supply unit.
    However, the manual maneuvering and handling of the device by a service person leads to an increased handling cost when replacing the power salvage unit, as a service person must leave the transport truck driver's seat to maneuver and operate the safety device at the industrial truck to replace the power salvage unit.
    The object of the present invention is to provide a mounting frame which enables a simple loading of the mounting frame with the power supply unit in the installation space of the industrial truck and a simplified handling of the solution when replacing the power supply unit.
    This is achieved by the invention in that the mounting frame is provided with a locking device, with which the mounting frame is secured in the mounting space against sliding, where the mounting device is maneuverable with a fork claw of the load truck of the transport truck when inserting the load fork into the mounting frame insertion channels. the load fork from the mounting channels' plug-in ducts in one stroke. According to the invention, the mounting frame is thus provided with a lifting device, which when changing the power supply unit automatically when inserting the forklift truck's fork claws into the corresponding plug channel, is actuated from the stroke to the unloading layer and when the forklift truck's fork claws are ejected from the corresponding plug channel. Such a maneuverable device through the forklift or fork claws of the transport truck when changing the power supply unit enables a simple loosening of the mounting frame against sliding laterally out of the mounting space, where no further manual operation is required and thus takes place without additional handling cost. The automatic maneuvering of the device by the fork claws of the transport truck further leads to the fact that no monitoring of the position of the laser device by a sensor device is required, so that an insensitive laser device is provided due to the lack of a sensor device which has a low manufacturing cost.
    According to a preferred embodiment of the invention, the welding device comprises at least one welding means, which in the welding layer cooperates with the laser recess in the mounting space of the industrial truck. With one or more welding means, which in the welding layer cooperate with the corresponding laser recess, which is formed in the mounting space of the industrial truck, a simple design and things welding of the mounting frame and darpa present power supply unit can be designed in the lateral direction of the industrial truck, which is also suitable for a high weight power supply unit. .
    According to a preferred embodiment of the invention, the welding means is manoeuvrable with an operating means cooperating with a fork clone between the welding layer and the unloading layer. With an operating means arranged in the insertion channel, the welding means can be easily maneuvered into the welding layer by inserting the fork claws into the insertion channel or when the fork claws are carried out of the insertion channel in the welding layer.
    Accordingly, according to an embodiment of the invention, the claw is advantageously advantageous and the welding means are pre-tensioned with a spring device in the welding layer. In this case, it is ensured in a simple manner that the welding means when performing the fork claws from the insertion channel is maneuvered by the spring device in the welding layer, so that the welding device according to the invention has a high operational reliability and is designed without sensor devices to monitor the welding device.
    According to a preferred embodiment of the invention, the operating means is coupled with a gear device to the welding means. Over a corresponding gear device, the actuator maneuvered by the fork claws can easily maneuver the lasing means between the lasing layer and the unloading layer.
    According to an embodiment of the invention, the welding member is advantageously designed as a rotatable laser arm, which is provided with a welding bolt, which cooperates with a laser socket designed as a welding nut in the mounting space of the industrial truck. With a rotatable locking arm, the locking bolts of which in the welding layer co-operate with the locking nut in the mounting space and engage in it, a simply constructed and stable lateral mounting of the mounting frame can be achieved, which is suitable for high acting forces and armed for a high weight power supply unit.
    Particularly advantageously according to an embodiment of the invention, the operating member is designed as a rotatable operating arm, which is provided with a control plate for maneuvering through the fork claws, which is arranged in the insertion channel of the mounting frame. With a rotatable control arm, which is provided with a control plate arranged in the plug-in channel, it can be easily set and at a reasonable cost by inserting or making out the fork claws in the plug-in channel.
    Particularly advantageous is the fact that the maneuvering plate closes the plug channel completely or partially. In this way it is achieved that the control plate signals the age of the control arm and the armed device, and in particular there is an optical signal for the stroke of the device 15. In the stroke, in which the control plate 5 at least partially closes the insertion channel, the armed p5 is simply signaled optically that the device is in the load layer and that the mounting frame is in the mounting space.
    The optical signal can be further amplified and made clearer to karma again, cla the control plate is color-marked with the corresponding signal color.
    According to a further embodiment of the invention, the control arm is rotatably mounted around a first axis of rotation and the arm around a second axis of rotation, the axes of rotation being arranged at a distance from each other. With such an arrangement of the rotatable control arm and the rotatable laser arm, a movement connection between the control arm and the laser arm 5 can easily be established by a corresponding gear device.
    As gear units, various suitable gear units can be used, for example a toothing between the control arm and the arm, which, for example, enables a corresponding conversion of the axis of rotation of the control arm to a reduced range of rotation of the laser arm.
    According to a preferred embodiment of the invention, the gear device is designed as a cam disc gear device. Such a cam disc gear device has a robust construction and enables a lawless manufacturing cost a trouble-free and dirt-free operation of the welding device.
    In addition, such a camshaft gearing device easily enables a clearance and a corresponding gearing to convert the range of rotation of the fork clone maneuverable maneuvering arm, which in a range of 900 is preferably rotatable within the insertion channel, to a reduced range of rotation of the laser arm
    The camshaft gear device is suitably formed by a curved path and a maneuvering pin cooperating with the curved path. Such a camshaft gear device enables at law manufacturing cost a things and trouble-free operation of the welding device.
    According to a preferred embodiment of the invention, the cam web is formed by a nut-shaped recess of the operating arm, in which the operating pin arranged at the laser arm is guided.
    According to a preferred embodiment of the invention, the laser recess is formed in a floor area of the transverse beam arranged in the mounting space of the industrial truck, where guide surfaces Jr are formed between the transverse beam and the mounting frame, which form aids in inserting and executing the mounting frame in the mounting space. With such aids, which the contractor acts in the longitudinal direction of the vehicle and in the vertical direction, the insertion of the mounting frame with the power supply unit into the mounting space through the transport truck can be simplified and shortened in time.
    By means of the invention, a respective welding means can be arranged in a single plug-in channel of the mounting frame or in the plug-in channels of the mounting frame. By using such a welding means in an insert channel of the mounting frame or two or more welding means in the mounting channels of the mounting frame, which can preferably be simultaneously maneuvered by the fork claws, by selecting the number of welding means in the insert channels depending on the power supply unit, for example a battery bank. Loading of the mounting frame with the present power supply unit laterally in the mounting space of the industrial truck is achieved.
    The invention further relates to an exchange system for replacing a power supply unit of an industrial truck, in particular a counterweight forklift, in the horizontal direction with the aid of a transport truck, wherein the exchange system comprises a mounting frame provided with a lifting device according to the invention for receiving the power supply. With the mounting frame according to the invention, by the automatic maneuvering of the device through the fork claws of the transport truck, a realization of the mounting frame with the power supply unit in the industrial truck mounting space and a simple handling of the device when replacing the mounting frame can be achieved.

    The loading device V according to the invention is manoeuvrable with the fork claws 16a and 16b of the load fork 16, respectively, when inserting the load fork 16 of the transport truck T into the insert channels 15a, 15b of the mounting frame G in the unloading position. When performing the load fork 16 out of the mounting channels 15a, 15b of the mounting frame, the welding device V is maneuvered in the welding layer. In the embodiment shown, the unloading device V comprises two means 30a, 30b, which in each case cooperate with a locking recess 31a, 31b in the mounting space A of the industrial truck F.
    The laser recesses 31a, 31b are each formed by a welding nut, which in the embodiment shown are formed at the upper side of the transverse beam Q.
    Each welding means 30a, 30b is manoeuvrable with an operating means 32a, 32b cooperating with the fork claws 16a, 16b between that stroke and the dissolution stroke.
    The welding means 30a and 30b, respectively, are each designed as rotatable around a vertical axis of rotation Si arm 33a and 33b, respectively, which is provided with a nut 34a and 34b, respectively, which cooperate with the recess 31a and 31b, respectively, in the mounting space A of the industrial truck F. The laser arms 33a, 33b each of the arms in the vertical direction spaced apart from each other, between which the struts 34a, 34b of the engagement member 31a, 31b are arranged and fixed. Figure 6 shows, for the sake of clarity, this design of the arm 33a without the upper arm.
    The actuators 32a, 32b are each designed as a control arm 35a, 35b rotatable about a vertical axis of rotation S2. The operating arms 35a, 35b are for maneuvering through the corresponding fork claw 16a, 16b each provided with an operating plate 36a, 36b, which is arranged in the corresponding plug-in channel 15a, 15b.
    The axis of rotation S1 of the load arm 33a and 33b, respectively, is arranged from the axis of rotation S2 of the associated control arm 35a and 35b, respectively, spaced from the mounting frame G.
    In order to be able to maneuver the associated arm arm 33a and 33b, respectively, when maneuvering the control arm 35a and 35b, the control arm 35a and 35b, respectively, is coupled to the associated arm arm 33a and 33b, respectively, with a gear device 40a, 40b. The gear device 40a and 40b, respectively, are in the embodiment shown formed as a cam disc shaft, which comprises a cam track 41a, 41b and a maneuvering pin 42a, 42b cooperating with the cam track 41a, 41b. The cam track 41a, 41b is formed by a nut-shaped, circular-like Wit recess in the operating arm 35a, 35b, in which the operating pin 42, 42b engages and is guided. The operating pin 42a and 42b, respectively, are in this case arranged and fixed analogously to the welding bolts 34a, 34b between the arms of the two welding arms 33a, 33b.
    In order to position the lifting means 30a and 30b, respectively, a respective spring device 45a and 45b, respectively, is provided. The spring device 45a and 45b, respectively, is in the embodiment shown designed as a torsion spring, which is in force coupling with the operating arm 35a and 35b, respectively, and biases the operating arm 35a and 35b, respectively, and thus the welding arm 33a and 33b, respectively, in the welding layer.
    In the welding position of the welding device V, the I5 arm 33a and 33b, respectively, engage with corresponding welding bolts 34a and 34b, respectively, in the welding nut 31a and 31b, respectively, of the crossbeam Q. In the locking layer, the control arm 35a and 35b, respectively, with the control plate 36a and 36, respectively, are arranged perpendicular to the longitudinal axis of the plug channel 15a and 15b, respectively, so that in the load layer of the control arm 35a and 35b the control plate 36a and 36b, respectively, deactivate the front, 15b and thereby provides an optical signal for the stroke of the device VI5.
    The fork claws 16a, 16b of the load truck 16 of the transport truck T are inserted into the insertion channels 15a, 15b for disassembly of the power supply unit E into the mounting space A of the industrial truck F, rotated by the corresponding inward fork claws 16a and 16b via the control plate 36a and 36b respectively. and is pressed correspondingly against the vehicle center F of the industrial truck, where over the camshaft shaft 40a and 40b the arm 33a and 33b, respectively, are rotated about the axis of rotation Si from the welding layer to the unloading layer, the welding bolts 34a and 34b being rotated out of the recesses 31a and 31b, respectively, as shown in Fig. 7.
    The camshaft shaft 40a, 40 allows a clearance which allows the range of rotation of the operating arm 35a, 35b, which is arranged perpendicular to the longitudinal axis of the insertion channel 15a and 15b, respectively, and in the unloading layer substantially parallel to the axis of the insertion groove 90a 33a and 33b, respectively, are housed in a reduced rotation area. The camshaft gear 40a, 40b further ensures that the laser arms 33a and 33b are first maneuvered with the operating arms 35a and 35b from the welding layer to the unloading layer, respectively, the control arms 35a and 35b are almost completely turned and then with the fork claws 16a, 16b continue correspondingly far into the insert channels 15a, G can certainly be taken up.
    After mounting the power supply unit E in the industrial truck F's mounting space A out of the plug ducts 15a, 15b, the control arms 35 and 35b and the laser arms 45a and the camshafts, respectively, are coupled to the laser arms 45a and 40b, respectively. .
    The axes of rotation S1, S2 of the welding means 30a, 30b are as explained in connection with Fig. 6 arranged in the corresponding housing of the mounting frame G, whose inner cradles 50a, 50b slope in the transverse direction of the vehicle and are arranged inclined to the insertion channels 15a, 15b and formed tip of the crossbeam Q forms guide surfaces 51a, 51b, which upon insertion of the mounting frame G into the mounting space A allow a centering and thus form an aid 20, which facilitates the insertion of the mounting frame G with the power supply unit E in the mounting space A.
    An additional aid 20, which facilitates the insertion of the mounting frame G with the power supply unit E in the mounting space A, is formed by the angular guide rails 52a, 52b arranged at the mounting frame G, which extend parallel to the crossbeam Q. The guide rails 52a, 52b guide the mounting frame G A through side sides 53a, 53b formed by the crossbeam Q and furthermore possible with an angular part 54, which engages under an upper step plate of the crossbeam Q., a main stop as guide surface 55 in the vertical direction, which delimits the inclination of the mounting frame G with the load fork 16. disassembly of the power supply unit E arranged in the mounting frame G, avoid a collision with the frame 7.
    From a longitudinal beam 57 shown in Figures 3 and 7, which is arranged between the insertion channels 15a, 15b at the mounting frame G, a duct stop is formed as an additional guide surface 56, which upon insertion of the mounting frame G cooperates with the Q V-shaped tip of the crossbar and prevents a further insertion of the mounting frame G into the mounting space A.
    The mounting frame G according to the invention with the loading device V maneuverable by the forklift 16a, 16b of the transport truck T makes it possible to load the mounting frame G into the mounting space laterally at a high cost, which also at high weight of the power supply unit E allows loading in the side. The maneuvering through the fork claws 16a, 16b entering the transport trucks 15a, 15b into the transport channels 15 further leads to a simple handling by an automatic maneuvering in the unloading layer. When the fork claws 16a, 16b of the transport truck T are made out of the insertion channels 15a, 15b in connection with the spring device 45a, 45b, an automatic maneuvering in the load layer is given, the insertion channels 15a, 15b further providing the operating plates 36a, 36b giving an optical signal and optical signaling. without additional sensor device.
    The invention is not limited to the embodiment shown, in which in each plug-in channel 15a, 15b a device 30a, 30b is arranged, which is preferably maneuvered simultaneously with the insertion of the fork claws 16a, 16b in the plug-in channels 15a, 15b. It is also possible to arrange in a plug-in channel 15 and 15b, respectively, a single means 30a or 30b. 13
