    Batting group for railway maintenance machines capable of batting the ballast under the sleepers of the track, both single and double 5 Field of the invention
    The invention falls within the technical sector of machines dedicated to the maintenance and construction of railways, more specifically in relation to batting groups of track batting machines. Background of the invention
    10 The passage of the different vehicles that circulate on the railways and their exposure to weather conditions, modify the qualities of the track and the rest of the elements on which it sits. To correct the loss of these qualities and avoid the impossibility of using the road, it is necessary to carry out a series of maintenance work. With the technique currently in existence, the process of correcting in the direction
    The vertical and horizontal track is made by machines equipped with leveling and alignment groups, also known as lifting and ripping equipment. The batting group is in charge of shifting each crossbar in its new position by compacting the stone beneath it. Depending on the type of machine and batting group, it is currently possible to hit from one to four sleepers at the same time.
    20 In general, the batting groups currently in existence are characterized by providing a closing effort to the bats that penetrate the ballast bench and fit the sleepers by flowing the stones under them. This effort has a fixed component, exerted by a hydraulic cylinder and an oscillatory component. The most common solution to generate this vibratory stress is by means of an axis with eccentric geometry.
    25 which is rotated at certain revolutions to achieve the desired frequency. There are also other solutions, such as the one presented in the patent ES-2027048-B1, in which this oscillating effort is achieved by the action of a system formed essentially by a hydraulic actuator powered by means of supply distribution valves controlled in a cyclic sequence. by one or more distributors.
    30 There are several solutions regarding the time and manner of application of the


    vibratory component of bat effort. As already mentioned, the most common solution to generate this vibratory effort is by means of an axis with eccentric geometry which is rotated at certain revolutions to achieve the desired frequency. This system is usually accompanied by a large flywheel, so the ability to vary the frequency of vibration is very low. However, according to Spanish patent application P201530363, a batting group governed by a high frequency solenoid valve is known. In this invention a differentiation is established between the oscillation frequencies during the penetration of the bat into the stone (25Hz) and the frequency during the closing of bats (35Hz). During the rest of the cycle the component disappears
    10 vibratory
    Another characteristic of batting groups is the way to adapt the opening of bats to differentiate the operations carried out in areas where the lane rests on double sleepers, instead of one that is the most common. For this, the machines usually limit the hydraulic cylinder stroke that the bats open and close. This limitation usually consists of a metal body articulated on the sleeve of the bat closing cylinder. This body limits the stroke of the rod in simple sleeper operations. When a double sleeper has to be batted, a secondary cylinder removes the articulated body allowing the rod to reach its maximum travel. From US-6401623-B2 a system is known to eliminate this hydraulic-mechanical system by hydraulically limiting the volume of
    20 oil entering the chamber of the cylinder in case of batting in a simple sleeper. Description of the invention
    It is necessary to offer an alternative to the state of the art that covers the gaps found therein.
    To this end the present invention provides an advance in the penetration capacity of
    25 batting groups in the ballast bed, by modifying the parameters that govern the oscillating component of the bat effort. This is applicable for both single and double sleeper batting.
    Specifically, this invention relates to a batting group for railway maintenance machines capable of hitting the ballast under the sleepers of the track, single and double, comprising a chassis arranged to ascend and descend position by means of a cylinder, a main axis on which rotate two inner cylinders arranged to transmit the vibration and closing movement to inner carriers, two outer cylinders arranged to transmit the vibration and closing movement to some portabates


    outside where each of inner and outer cylinders are governed by a high frequency solenoid valve configurable in voltage, frequency and wave geometry where the control of said solenoid valves is arranged to transmit a primary high frequency oscillation (f1) and a secondary low frequency (f2).
    5 As can be seen, unlike the previous solutions, the mechanism of the invention comprises a vibration cylinder, with a central chamber in which the movement of the rod, called vibration and closure, which is governed by a high solenoid valve configurable frequency in voltage, frequency and wave geometry.
    Without loss of generality, this way of governing the vibration and closing rod is
    10 applicable to a cylinder composed of a total of three coplanar stems, where the one occupying the central position is governed by the high frequency valve. The two outer rods are oriented in the opposite direction to the central direction, and they set the batting position for single or double sleeper batting.
    The particularity of the invention is given by the addition of a second component.
    15 oscillatory to the movement of the bat during penetration into the ballast bed. For this, two different configurations of the solenoid valve control parameters are available that respond to a square wave of 48Hz frequency. Each of the two configurations has a slight offset in the amplitude of the wave, so that one of them tends to pull the rod and the other to put it, within its oscillatory movement. From
    In this way, by feeding the solenoid valve alternatively with these two configurations, a second oscillatory movement is achieved that overlaps the primary 48Hz vibration generated by the square wave. In the specific case of this invention, this change of parameters occurs 10 times per second, that is, a composition of a high-frequency movement -48Hz-and a low -10Hz- movement is obtained.
    25 An offset in amplitude has been chosen to achieve net displacement to one side or the other. Without loss of generality, this effect can be achieved by maintaining the amplitude symmetry and modifying, for example, the percentage of time that the valve allows the passage of oil to one and another chamber of the cylinder.
    The double horizontal swing of the bats adds to the vertical descent of the batting group
    30 during penetration into the ballast bed. A notable improvement in penetration time and reduced ballast wear have been empirically proven. The descent of the group is achieved by the usual components, that is, guided by a pair of columns fixed to the machine and moved by a hydraulic cylinder, also fixed at its end


    later.
    Once the desired batting depth has been reached, the descent of the group stops and the solenoid valve signal is modified, going to a third parameter configuration. This configuration also corresponds to a square wave, in this case 35Hz of
    5 frequency, and offset in amplitude so that the advance of the bat is favored. In this way the superposition of the movements of vibration and closing of bats is achieved, which is traditionally generated with a linear movement of the rod and an excitation of the cylinder by means of the rotation of an eccentric axis.
    These and other advantages are apparent in light of the detailed description of the invention. 10 Brief description of the drawings
    Detailed descriptions of the invention will be more fully understood from the following figures with reference to the main elements that should be considered in an illustrative and non-limiting manner, in which:
    Figure 1 shows the perspective view of a batting group in detail where its main construction elements are indicated.
    Figure 2 shows in an enlarged way the most prominent components of that first figure.
    Figure 3 shows the side view of a batting group in three different positions, in which the vertical displacement of batting is appreciated. It also illustrates the 20 different elements involved in the adaptation of the group to the bat in a simple naughty
    or double and in vibration and closing bats.
    Figure 4 is a graph in which the typical downward movement of a bat is represented. The displacement (left z axis.) In time (right z axis.) Is the result of a continuous vertical descent and a vibration of a frequency (f) and an amplitude (A) according to
    25 x axis
    Figure 5 includes two graphs. The penetration and closing movements of a bat according to the invention are shown in the graph on the left. The first part, during the first 0.5s, represents the displacement in time (right z axis) resulting from a continuous vertical descent (left z axis) and the composition of two vibrations of 30 frequencies (f1 and f2) and amplitudes ( A1 and A2) along the upper x axis. The second to the part, to


    after 0.5 seconds, it occurs at a constant depth (left z axis) and represents the closing movement of bats (lower x axis) in this period. The graph on the right represents the evolution in time of the signal received by the solenoid valve to govern the movement represented in the left graph. 5 Detailed description of the invention
    The elements defined in this detailed description are provided to help a global understanding of the invention. Accordingly, those skilled in the art will recognize that variations and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Further,
    10 The detailed description of sufficiently known functions and elements are omitted for reasons of clarity and conciseness.
    The invention relates to a working group of a railroad maintenance machine. The task force in question is that of batting, with the ability to operate on two sleepers simultaneously, compacting the existing stone under each one. The
    15 electronic equipment and systems necessary to measure the track and govern these work equipment are similar to those currently used in the art and therefore are beyond the scope of this description.
    Each work or batting group, as can be seen in Figures 1, 2 and 3, is mainly composed of a main body, called a chassis (12), which can ascend and descend to the work position, guided by a pair of columns (13) fixed to the machine, by means of the chassis lowering cylinder (14). The chassis contains a main shaft (15), on which two inner cylinders (11) of the batting group rotate, said cylinders
    (11) They consist mainly of a rod (3) that transmits the vibration and closing movement to the inner bumpers (7) through a joint shaft (4). In turn, these inner bumpers (7) rotate on an axis (6) coupled to the chassis. At the rear of each inner cylinder (11) an outer vibration cylinder (10) is coupled by means of a connecting shaft (16). Each outer cylinder (10) is mainly composed of three rods, the central rod (1) transmits the vibration and closure of the outer carrier (8) through a joint shaft (4). In turn, these outer bumpers (8) rotate on an axis (5)
    30 attached to the chassis. The outer rods (2) located at the rear of the cylinder
    (10) are responsible for the positioning of the outer bumpers (8) in single-batter (18) or double (17) batting configurations. In this way these stems remain fixed to minimize wear of consumable parts.


    Each cylinder is commanded by its corresponding high frequency solenoid valve (9). Figure 5 shows the excitation signal of the valve that allows to achieve the penetration mode claimed according to the invention. For this, two different parameter settings are available. The first parameter configuration (20) has as its 5 main characteristics a vibration frequency f1 = 48Hz, and an offset of + 50% in amplitude that favors a positive net displacement of the bat along the x-axis, within an oscillatory amplitude movement A1 = 6mm. Similarly, there is a second parameter configuration (21) symmetrical to the previous one with the same frequency and amplitude -48Hz and 6mm-, with an offset of -50% in amplitude that favors a
    10 negative net displacement of the bat along the x axis. By means of a sequence of alternation between the two parameter configurations (20 and 21) every 0.05 second, the superposition of a primary oscillatory movement of f1 = 48Hz and A1 = 6mm is achieved with a secondary one of f2 = 10Hz and A2 = 16mm , due to said alternation of parameters.
    Once the desired batting depth is reached, the signal of the
    15 valve excitation with a third parameter configuration (22), characterized by a frequency f3 = 35Hz and an offset amplitude + 50%, so that the net displacement during a cycle is positive, that is, the movement occurs of closing bats.
