    The invention relates to an accessory for a log grapple, which log grapple is intended for a wheel loader and which comprises: - a fixedly fitted part comprising a spike, is provided with tunneling for the log grapple prong to take over the accessory to the log grapple.
    For example, at sawmills, the loads of timber trucks or railcars are unloaded bundle by bundle with a log grab arranged in a wheel loader, which are also called log pliers. Log grapples are primarily used to process long timber in various sectors of the wood processing industry. In addition to unloading the loads, they can be used to move wood internally at the sawmill and also to sort the timber. All this activity typically takes place in the sky under weathering.
    In winter, activities are strained by snow and ice. During heavy and continuous snowstorms, the maintenance of wheel loader driving routes requires almost constant plowing, which binds resources. The work may involve the work of one wheel loader or even an external contractor may have to be used. The snow and poles of the log field should be removed in order to provide a safe a 30 driving route for the implements. In addition, all kinds of & unevenness in the log field place a heavy strain on large machines, especially when they are moving at full load. In this case, the weight of a large implement can be up to tens of tons.
    Well-maintained driving routes would speed up the smoothness of work and thereby also affect work efficiency.
    The object of the invention is to provide an accessory for a log grapple. The characteristic features of the invention are set out in claim 1.
    With the invention, it is possible to perform property maintenance operations, such as plowing, with a wheel loader equipped with a log grapple. The attachment and the plow arranged on it can be easily and quickly connected to the log grapple. The invention also makes it possible to reorient the plow in a simple and effortless manner. For this purpose, the accessory does not require any separate means or force required for it. The device according to the invention therefore has all the same features as a hydraulically operated plow. Everything in the device works mechanically. In addition, the attachment can be connected and the plow connected to it can be turned quickly and even without descending from the driver's machine. Other additional advantages achieved by the invention will be apparent from the specification and features from the appended claims. The invention, which is not limited to the embodiment shown below, will be described in more detail with reference to the accompanying drawings, in which OF
    SK Figures 1a and 1b show an example of a wheel loader with a log grapple with the grapple closed and open, & Figure 2 shows a wheel loader with its log grapple equipped with a 1i-N device according to the invention, ,
    Fig. 4a shows a side view of the push rod of the attachment, Fig. 4b shows a top view of the push rod of the attachment Z, Figs. 7c show the accessory in its various orientations.
    Figure 1a shows an example of a wheel loader 101 equipped with a log grapple 100. The wheel loader 101 is frame-controlled. In this case, it comprises two parts, the front part 101.1 and the rear part 101.2. The log grapple 100 is arranged in the front part 101.1, which has a lifting device 106 known per se with hydraulic actuators. In the rear part 101.2, in turn, the cab 108 of the wheel loader 101 is arranged. Both parts 101.1, 101.2 also have pairs of wheels 109.1, 109.2. The front part 101.1 and the rear part 101.2 are articulated between them to implement frame control for a wheel loader
    101. The articulation point is denoted in Fig. 1a by reference numeral 107. In it, the front and rear parts 101.1, 101.2 are connected to each other by hydraulic actuators (not shown). They cause the parts 101.1, 101.2 to turn relative to each other and thus also to control the 3 wheel loaders 101. x + 30 The log grapple 100 arranged on the wheel loader 101 is intended & for example for the wheel loader 101 and is attached to its lifting device 106 in a manner known per se. The log grapple N 100 comprises a fixedly fitted part 102, a lower jaw, and a movably fitted part 104, an upper jaw. The lower jaw 102 includes a spike 103. In this case, it includes two spikes 110 on either side of the fixedly fitted portion 102, now forming a fork in the grapple. The fixedly fitted part 102 forms a side-opening U-profile.
    The upper jaw, i.e. the movably arranged part 104 of the log grapple 100, in turn, can be pivoted and thus also loaded towards the fixedly fitted part 102, i.e. the lower jaw, in order to provide a detachably closable log grapple 100. To this end, the upper jaw 104 is pivotally articulated to the fixed part 102 at one end thereof and provided with corresponding actuators. At its other, opposite end, the log grapple 100 closed, the upper jaw may correspond to the lower jaw, more particularly, for example, to the fork tips for holding a load 105 in connection with the log grapple 100 when it is closed. In other words, when closed, the parts 102, 104 of the log grapple 100 form a main closed circuit, a grapple within which the load remains securely when it is transported by the wheel loader 101. Instead of a closed circuit, the load 105 can also be compressed by the movable part 104 towards the structures of the fixed part 102 and the housing formed by it. Fig. 1b, on the other hand, shows the situation with the log grapple 100 open, i.e. with the upper jaw turned up. In this position, it is possible to take or deliver a load to the log grapple 101.
    Fig. 3 shows an example of the accessory 10 for the log-N grapple 100 as seen from above and Fig. 6 as seen obliquely from the front. With the accessory 10, the possibilities of using the log grapple 100 can also be diversified for property maintenance. The accessory 10 comprises a 30 a body 11 and a pusher 14 pivotally fitted to the body 11. & The pusher 14 is pivotally fitted to the body 11. The accessory 10, and more particularly, now its body 11 N is provided with a tunneling 12 for the prongs 103 of the log grapple 100 to take over the accessory 10 and thus also to connect it to the log grapple 100. The tunnel 12 can be
    Hua also more specifically as a sheath or fork tunnels. A tunneling 12 is formed in the body 11 on its upper surface at opposite edges of the body 11. In this case, the tunneling 12 is parallel to the prong 103 of the log groove 100. In addition, the tunneling 12 5 is now formed in the shape of the lower jaw 102 of the log grapple 100. The height of the tunneling 12 then increases in the direction of the grapple 100 and lowers towards the tips of the fork. The large and high inlet of the tunneling 12 also allows the accessory 10 to be easily picked up in connection with the log grapple 100.
    The pusher 14 can be fitted with a tool, such as a road maintenance device 13, an example of which is the area plow 13 ". The plow 13 'can be used, for example, for plowing snow and also for removing debris. For plow 13", the pusher 14 has lugs 20 for plow 13 'or other similar road maintenance device 13. Thus, instead of the accessory 10, it is also possible to speak more specifically of an adapter or a coupling adapter. The accessory 10 further comprises a releasably lockable locking mechanism 15 arranged between the frame 11 and the pusher 14 in the direction of the road maintenance device 13 - 03 for positioning (Figures 7a to 7c) Here, positioning means more specifically to change the orientation 01 to 03 and to fix it for the work operation.The push rack 14 is provided with two or more orientations 01 to 03 in the N frame 11, into which it 5 can be unlockably locked. with locking mechanism 15. Trends 3 to 03 differ horizontally. x + 30 Fig. 4a shows the pusher 14 of the accessory 10 from the side & seen in cross section and Fig. 4b from the same top view S. The push stand 14 is articulated to the body 11 to change its horizontal orientation 01-03. The articulation point fitted to the frame 11 is numbered 21 in Fig. 3 and the articulation point fitted to the push stand 14 is numbered 22 in Figures 4a and 4b. The articulation can be realized, for example, by a pivot pin passing through the body 11 and the push stand 14. Trends 01 to 03 are shown in Figures 7a to 7c. In order to provide orientations 01 to 03, the locking mechanism 15 on the push stand 14 comprises two or more locking members 16 adapted to move and locking responses 17.1 to 17.3 arranged on the locking member 16. In the case of the embodiment, the locking member 16 is fitted to the body 11 of the accessory 10 and the locking stops 17.1 to 17.3 are fitted to the push stand 14. The locking member 16 belonging to the locking mechanism 15 is pivotally articulated to the body 11. To this end, the body 11 has flanges 23 forming articulation lugs 23 on its upper surface. 11 an opening through which it is possible to extend inside the body 11 and into the extension 27 of the push beam 14 fitted therein, into which the locking stops 17.1 to 17.3 are in turn fitted. Thus, in the locked position, the pin 26 extends at least up to or even through the locking stops 25 to 17.1 to 17.3.
    The S + locking member 16 is provided with a drive stop 19 for loading the locking member 7 16 into the locking stop 17.1 to 17.3 to provide a lock. The drive stop 19 is arranged relative to the body 11 of the accessory 10 and in particular to the locking member 16 so that it can be loaded by the part 104 adapted to move the log grapple 100 and more particularly by the tip N of the upper jaw. In this case, the operating stop 19 can be pressed with the tip of the upper jaw to provide a locking. The operation will be described in more detail in the description a little later in connection with the operation description of the accessory 10. The drive stop 19 may be arranged between the pivot pin 25 and the locking pin 26 or on the locking pin 26.
    The locking member 16 is provided with a self-powered return 18 for unlocking. In this way, the unlocking also takes place without the need to leave the implement 101. According to one embodiment, the self-powered retractor 18 can be implemented with, for example, a tensioned coil spring 28 fitted to the pivot pin 25 shown in Fig. 3. Another way is to use rubber restorers 31 between, for example, the locking latch 24 and the body 11 (Fig. 6). It raises the locking latch 24 and thus lifts the locking pin 26 away from the connection of the locking stop 17.1 to 17.3. Figure 6 also shows the attachment lugs 32 of the support bar of the plow 13 'fitted to the push stand 14.
    Referring to Figures 4a and 4b, the locking stops 17.1 to 17.3 are openings, locking holes, arranged in the push stand 14. The locking stops 17.1, 17.3 are arranged on the push stand 14 in an arcuate arrangement. While on the arc of a circle with respect to the hinge point, the locking pin 26 hits the holes 17.1, 17.3 in different directions of the plow 13 ”. It allows the pusher 14 to be oriented on both sides with respect to one pivot point. At the base of the extension 27 of the pusher 14 before the spread 29, the cuts 30 allow the pusher 14 to pivot horizontally with respect to the body 11 and thus its orientation to the sides. Thus, the push stand 14 is narrower at the end of the locking stops 17.1 to 17.3. Spread 29 can be referred to here - also as a bumper beam. S 30 & The frame 11 and / or the push stand 14 may be a housing structure assembled from plate sections. It makes them strong and sufficiently rigid, also in the lateral orientations 02, 03 of the road maintenance device 13. When the accessory 10 is assembled, the pusher 14 is inside its housing structure formed by the body 11.
    up to 30 reductions for 27. Thus, the body 11 is adapted to partially enclose the pusher 14. The center of gravity of the pusher 14 and the road maintenance device 13 fitted thereto is arranged at a distance from the frame 11. This contributes to facilitating the horizontal orientation of the road maintenance device 13 by the lateral movement of the wheel loader 101. Next, the use and operation of the accessory 10 according to the invention will be described. The accessory 10 can be utilized, for example, in the maintenance of buses and areas. An exemplary application is the maintenance of a wood processing field and / or other similar area, which is inherently operated by, for example, a wheel loader 101 and with reference to which the operation of the accessory 10 when used with a wheel loader 101 will be described below. In a woodworking field or the like, the operation is typically performed with a frame-controlled wheel loader
    101. Here, a wood processing field refers, for example, to the yard areas of wood processing plants, such as sawmills. Instead of the wood processing field, the applications of the accessory 10 according to the invention are equally the entire area of the property, i.e. also on routes other than where the timber is stored and moved. Some other examples of lanes maintained by the accessory 10 may be, for example, roads and light traffic lanes, and areas such as parking areas. N The operation is performed with an accessory 10 5 according to the invention equipped with a road maintenance device 13, such as a dozer 7 plow 13 ”in the log grapple of the frame-controlled wheel loader 101 - 100. = & Figure 7a shows a situation where the plow 13 'is directed S N The additional device 10 can be picked up on the log grapple 100 in all its orientations 01 to 03. This is done by driving the log grapple 100 with the wheel loader 101 open, i.e. by moving the grapple.
    the part 104 raised upwards towards the accessory 10 approaching it from the side of the body 11. With the lifting device 106 and the associated tilt, the height of the log grapple 100 and the position of the prong 103 are set so that the prongs 110 of the prong 103 are substantially at and parallel to the level of the tunneling 12. In this way, the spikes 110 of the prong 103 can be threaded inside the tunneling 12, i.e. the sheaths, and the accessory 10 is picked up in connection with the log grapple 100.
    After picking up and taking over the accessory log of the accessory 10, the 13 ”orientation of the plow is locked. This is done by closing the log grapple 100 with its movable part 104. In this case, the tip of the upper jaw of the log grapple 100, i.e. the movable part 104, is pressed against the operating response 19 of the locking member 16 of the accessory 10 arranged on the upper surface of the body 11. As a result, the locking member 16 and the locking pin 26 therein are pressed downwards, preferably applying to the central locking stop 17.1. Figure 5b shows this locked situation. With the upper jaw of the grapple, the accessory 10 is also made to remain in the grapple 100, for example in deceleration situations, if the plow 13 'is supported, for example in air. Plowing with the plow 13 ”takes place when the groove 100 is in the lower position, so that the lower edge of the blade of the plow 13 'hits the surface to be plowed as the wheel loader 101 moves.
    When it is desired to change the horizontal orientation of the plow 13 ', it N occurs as follows. The plow 13 ”is lifted off the plowed surface 5 by a lifting device 106. For orientation, it is advantageous to make the auxiliary device 10 slightly in such a position that the plow 13 'is - in a higher position than the stern of the body 11. When the wheel loader a 30 101 is in place, for example, a small reflective steering movement is made to change the direction of the plow 13 ”. Since the wheel load S and 101 are frame-controlled, the steering movement also affects its front part 101.1 and thus also its lifting device 106 and the grapple therein. It follows that
    10 is subjected to a lateral force which tends to turn it horizontally.
    The reflective steering movement is directed in the direction in which the plow 13 ”is to be turned.
    Thus, in the case of Fig. 7b, the movement takes place to the left and in the case of Fig. 7c to the right.
    Thus, one can speak of a horizontal or horizontal orientation.
    The grapple 100, i.e. the orientation lock, is opened at the end of the lateral movement or at its end.
    When the grapple 100 opens, the part 104 adapted to move it, i.e. the upper jaw, disengages from the locking actuating stop 19 and thus the locking of the plow 13 'orientation opens.
    Figure 5a shows this situation.
    As a result, the push bar 14 is free to pivot relative to its pivot point 21 fitted to the body 11.
    The reflective movement is obtained in such a way that, immediately as a continuation of the turning movement in one desired direction, a counter-steering movement is performed, the grapple still open.
    In this case, the control of the implement is, for example, returned to the straight-ahead position.
    When the grapple is open, the locking does not work and the pusher 14 of the accessory 10 can turn in relation to its articulation point 21 in the original first direction of movement.
    When the desired orientation is reached, the grapple is closed again and as a result the changed orientation of the plow 13 ”is locked.
    Thus, the orientation 01 to 03 of the road maintenance device 13 is again locked by the part 104 of the block groove 100 adapted to move. A small repair N movement may also have to be made if the driver of the wheel loader 100 5 is untrained with the accessory 10, i.e. the reflective movement has not been sufficient. , the timing of opening or closing the grapple is incorrect or the position of the attachment 10 in the grapple S 30 sa is suboptimal.
    However, the connection and / or reorientation of the accessory 10 takes place relatively quickly and also without the need to get out of the machine.
    Thus, the orientation 01 to 03 of the road maintenance device 13 fitted to the accessory 10 can be changed simply and easily by the steering movement of the wheel loader 101.
    Instead of turning the plow 13 'as described above with the plow 13' in the air by slightly loosening the upper jaw or flap of the log grapple 100 and swinging the machine 101, it can also be done with the plow 13 on the ground. In this case, the plow 13 ”is pushed against the ground in the direction in which it is to be turned. The plow 13 'is then locked in place again by pressing the flap closed. Plowing can then be performed by driving the wheel loader 101 forward with the plow 13 ”against the ground. Similarly, in this case too, the reorientation of the plow 13 'is based on the steering movement of the implement 101. With the invention, the driver of the wheel loader 101 can take advantage of the moments of a few minutes that occasionally remain from the actual work run and plow the areas clean. Then you don’t have to wait for someone to come and plow. Once the tire is removed and the icy slippery surface breaks, the driving route is safe again. The operation can be performed in addition to the permanent operating environment of the wheel loader 101, for example in its neighborhood. In addition, the invention either even eliminates or at least reduces the need for sanding and salting. Well-maintained driving routes speed up work flow, which affects work efficiency and safety.
    N A very significant advantage is also that the connection 5 of the accessory 10 and in particular the change of its orientation does not require any 7 hydraulic actuators to the accessory 10, the associated connections or hydraulic force to perform it, S 30, but is carried out entirely mechanically. This substantially simplifies the implementation of the accessory 10 and makes it virtually maintenance-free. In the invention, therefore, the control function of the frame-controlled wheel loader 101 is utilized in an ingenious manner to change the horizontal orientation of the accessory 10 connected to the log grapple 100. The plow 13 'is quickly connected
    to the wheel loader 101 and the direction can be changed in just a few seconds. In addition, the connection of the accessory 10 to the wheel loader 101 does not involve, for example, the connection of hydraulic hoses.
