Description

Technical Field

[0001] This invention relates to the field of track maintenance equipment technology, and in particular to a railway track pad replacement vehicle. Background Technology

[0002] The rubber pad under the rail is an important component of railway tracks, located between the rail and the sleepers. In the railway track structure, the rubber pad provides elasticity and insulation. Under repeated train loads, the rubber pad can easily lose its elasticity or even crush, causing increased wheel-rail impact and hindering train operation. Therefore, the rubber pads laid on the underside of the track need to be replaced after a period of service.

[0003] An existing type of machinery for placing railway track pads includes a traveling vehicle, a track lifting device, and a pad placement device. The track lifting device and the pad placement device are installed on the traveling vehicle, which can travel along the railway track. The lifting device can raise the railway track, creating a gap between the track and the sleeper. The pad placement device inserts rubber pads into the gap between the track and the sleeper.

[0004] The existing machine can only place the pads, but cannot remove the old pads. The old pads still need to be removed manually, so the work efficiency is not high. Summary of the Invention

[0005] This invention provides a railway track pad replacement vehicle for replacing the pads under the railway tracks.

[0006] This invention provides a railway track pad replacement vehicle, comprising: a vehicle body; a track lifting device mounted on the vehicle body for lifting the track upwards; a pad removal device disposed on the vehicle body, including a first pusher assembly movable to a first working position to push the pad out from under the track; and a plate loading device disposed on the vehicle body, including a plate loading box and a second pusher assembly movable to a second working position, the plate loading box for storing the pad, the pad being transferable from the plate loading box to the second pusher assembly, and the second pusher assembly pushing the pad under the track.

[0007] In one embodiment, the plate removal device further includes a pad receiving assembly, wherein the first pusher assembly and the pad receiving assembly are disposed opposite to each other in the length direction of the track, and the first pusher assembly can push the pad to the pad receiving assembly.

[0008] In one embodiment, the pad receiving assembly includes a storage box and a flip plate. A first pusher assembly can push the pad onto the flip plate, which can be flipped from a horizontal direction to a vertical direction to place the pad into the storage box.

[0009] In one embodiment, the second pusher assembly includes a tray, a slider, and a drive mechanism, which drives the slider to slide on the tray in a first direction to push a pad from the upper plate box to below the track.

[0010] In one embodiment, the plate removal device and the plate mounting device are arranged in pairs, and at least two pairs are provided. The at least two pairs of plate removal devices and plate mounting devices are arranged opposite each other on both sides of the width of the vehicle body.

[0011] In one embodiment, the railway track pad replacement car also includes a cleaning device mounted on the car body for cleaning debris under the track.

[0012] In one embodiment, the cleaning device includes a wind source and a blower nozzle that are connected to each other, the wind source supplying air to the blower nozzle, and the blower nozzle facing downwards from the track.

[0013] In one embodiment, the railway track pad replacement vehicle also includes a nut replacement device mounted on the vehicle body, which is used to remove or install nuts that secure the track.

[0014] In one embodiment, the nut replacement device includes a nut sleeve and a mandrel, the mandrel being disposed inside the nut sleeve and movable axially along the nut sleeve.

[0015] In one embodiment, the nut replacement device further includes a sleeve moving assembly and a nut storage box, wherein the sleeve moving assembly can move the nut sleeve to the inlet of the nut storage box.

[0016] In one embodiment, the nut storage box includes a box body and a nut placement platform.

The nut placement platform includes a nut placement position, and a sleeve moving assembly can drive the nut sleeve to move above the nut placement position.

[0017] In one embodiment, the rail pad replacement car also includes an oil injection device, which includes an oil nozzle facing a nut that is fixed to the rail.

[0018] In one embodiment, the railway track pad replacement vehicle further includes a detection and analysis system, which includes a surface-array lidar and / or a positioning module. The surface-array lidar is used to identify the sleeper skewness, sleeper spacing, sleeper-rail position, and track pad position. The positioning module is used for navigation and positioning of the railway track pad replacement vehicle, and determines the model of the track pad to be replaced based on the location of the railway track pad replacement vehicle.

[0019] In one embodiment, the track lifting device includes a hydraulic lifting assembly and a caliper assembly, wherein the hydraulic lifting assembly is mounted on the vehicle body and drives the caliper assembly to rise and fall.

[0020] Compared with existing technologies, the advantages of this invention are that the vehicle body is simultaneously equipped with a plate-removing device and a plate-raising device. After the vehicle body is mounted on the track, the track lifting device raises the track, and the first plate-pushing assembly then moves to the first working position, pushing the plate under the track out. The first plate-pushing assembly then transfers the plate stored in the upper plate box to the second plate-pushing assembly, which pushes the plate under the track to complete the plate replacement. This invention can not only complete the laying of platens but also remove used platens; the combined use of the plate-removing device and the plate-raising device reduces the labor intensity of workers and greatly improves work efficiency.

Detailed Implementation

[0040] The invention will now be further described with reference to the accompanying drawings.

[0041] See Figure 1 and Figure 2 This embodiment provides a railway track pad replacement vehicle, including a vehicle body 100, and a top plate device 200, a plate removal device 300, a cleaning device 400, a nut replacement device 500, an oil spraying device 600, a track lifting device 700, and a detection and analysis system 800, all mounted on the vehicle body 100. The vehicle body 100 is mounted on two tracks 901 of the railway line. The wheels 101 on both sides of the bottom of the vehicle body 100 roll in cooperation with the two tracks 901, driving the vehicle body 100 along the tracks 901. The detection and analysis system 800 includes a high-precision area array lidar 802 for sleeper 903 identification, a Beidou RTK module for navigation and positioning, a high-performance computer, a large-capacity battery 801, and several power cables and data cables. The high-precision area array lidar 802 is used to identify the skewness, spacing, and position of the sleepers 903, providing bolt center position data for the nut replacement device 500 and position data of the pads 902 for the upper plate device 200 and the lower plate removal device 300. The high-precision area array lidar 802 is mounted on a radar support rod 8021, which is located at the center of the front and rear faces of the vehicle body 100, at a height of 2.0m to 3.0m above the top surface of the track 901. The high-precision area array lidar 802 scans the planar features of the track 901 vertically downwards. The Beidou RTK module is used for navigation and positioning of the railway track pad replacement vehicle. Based on the location of the railway track pad replacement vehicle, the model of the replacement pad 902 is determined, including but not limited to the thickness and wedge shape of the pad 902. A high-performance computer processes the large amounts of real-time data sensed by various sensors, including the high-precision area array lidar 802 and the BeiDou RTK module, providing decision support for operations such as positioning of the pad 902 under the track 901 and tightening and loosening of the nut replacement device 500. A large-capacity battery 801 provides power to the high-precision area array lidar 802, the BeiDou RTK module, and the high-performance computer. Power and data cables are used for connections between the high-performance computer and the aforementioned sensors and batteries.

[0042] During operation, the detection and analysis system 800 runs in real time and issues various instructions to the railway track pad replacement vehicle. When the railway track pad replacement vehicle moves to the position where the operation is required, the nut removal device 500 first loosens the nuts fixing the rail 901 and the sleeper 903; then the rail lifting device 700 lifts the rail 901 upwards, creating distance between the rail 901 and the sleeper 903; the pad removal device 300 moves to the first working position and pushes the pad 902 out from under the rail 901, after which the pad removal device 300 returns to its initial position; after the pad removal is completed, the cleaning device 400 cleans the area where the removed pad 902 was located. Cleaning is performed to prepare for the installation of a new pad 902. After cleaning, the upper plate device 200 moves to the second working position and inserts the new pad 902 under the rail 901. After the new pad 902 is placed, the rail lifting device 700 slowly lowers the rail 901. The nut replacement device 500 tightens the previously loosened nuts, completing the fixation of the rail 901 and the pad 902. Finally, the oil spraying device 600 sprays rust-preventive oil onto the tightened sleeper bolts and nuts, thus completing the process of replacing one pad 902.

[0043] Combined Figure 3 , Figure 5 and Figure 16Furthermore, in this embodiment, the nut replacement device 500 consists of a tightening machine 505, a nut sleeve 502, and a return spring 504. The tightening machine 505 has forward and reverse rotation functions and can set the output torque according to requirements. Specifically, the tightening machine 505 and the nut sleeve 502 are coaxial; one end of the nut sleeve 502 is sleeved on the output shaft of the tightening machine 505, and the two can slide relative to each other; further, a return spring 504 is provided above the nut sleeve 502. Under the action of force, the nut sleeve 502 slides upward relative to the tightening machine 505, and the return spring 504 is compressed and stores energy. When the return spring 504 releases the stored energy, the nut sleeve 502 slides downward relative to the tightening machine 505 and returns to its original position under the elastic action of the spring; further, in order to make the nut sleeve 502 and the nut (bolt) better fit together, a beveled portion 5021 is provided at the insertion end of the nut sleeve 502, and the inner diameter of the beveled portion 5021 gradually decreases from bottom to top. The nut sleeve 502 has a return spring 504 and an angled portion 5021 to ensure accurate insertion of the nut when it descends and contacts the nut. Furthermore, to prevent the nut from falling off the nut sleeve 502, at least two mounting holes 5024 are provided on the sleeve wall. These two holes are arranged radially opposite each other at the insertion end of the nut sleeve 502. A steel ball 5022 and a tightening spring 5023 are sequentially positioned within the mounting holes 5024. The tightening spring 5023 applies a force to the steel ball 5022 in the axial direction of the nut sleeve 502, causing at least a portion of the steel ball 5022 to protrude from the inner wall of the nut sleeve 502. The return spring 504 ensures smooth and accurate insertion of the nut sleeve 502 into the nut. The tightening machine 505 has forward and reverse rotation functions; forward rotation tightens the nut, and reverse rotation loosens it. The tightening machine 505 allows for manual setting of the torque output as required. This torque setting function ensures that the nut reaches the specified torque requirement during tightening. The steel ball 5022 and the tightening spring 5023 prevent the nut from falling out of the nut sleeve 502.

[0044] Combined Figure 3 Furthermore, a nut storage box 503 is installed on the vehicle body 100, and the tightening machine 505 and the nut storage box 503 are arranged sequentially along the length of the vehicle body 100. The nut storage box 503 includes a nut placement platform 5032 and a box body 5031 connected to each other. The nut placement platform 5032 has a nut placement position 5033, and the nut placement position 5033 is connected to the internal space of the box body 5031. The nut storage box 503 holds new nuts, and a conveying component (not shown in the figure) is also provided inside the box body 5031. The conveying component can convey the nuts in the box body 5031 to the nut placement position 5033.

[0045] Combined Figure 2 , Figure 3 and Figure 5The sleeve moving assembly 501 includes a sleeve horizontal moving mechanism and a sleeve vertical moving mechanism. Specifically, the sleeve horizontal moving mechanism consists of a first slide rail 5061 and a first motor 5064, which are sequentially and fixedly connected above the vehicle body 100 along the length of the vehicle body. A first slider 5062 is slidably mounted on and slidably engaged with the first slide rail 5061. The first slider 5062 includes an internally threaded through hole. A third lead screw 5063 is disposed in the aforementioned internally threaded through hole. One end of the third lead screw 5063 is coaxially connected to the output shaft of the first motor 5064. The first motor 5064 drives the third lead screw 5063 to rotate, and the third lead screw 5063 drives the first slider 5062 to slide on the first slide rail 5061. The vertical lifting mechanism of the sleeve is specifically designed as follows: a first lifting component is fixedly connected to the first slider 5062. The first lifting component includes a first lifting slide rail 5067 and a first lifting slider 5066 that are slidably engaged. The first lifting slide rail 5067 is vertically arranged on the first slider 5062. A first cylinder 5065 is fixed to the first slider 5062 through a first cylinder bracket 5068. The first cylinder 5065 drives the first lifting slider 5066 to perform lifting and lowering movements. A nut replacement device 500 is fixedly connected to the first lifting slider 5066. The first lifting slider 5066 drives the nut replacement device 500 to perform lifting and lowering movements. The first slider 5062 drives the nut replacement device 500 to move along the length direction of the vehicle body.

[0046] The nut replacement device 500 can be moved to the nut placement position 5033 under the drive of the sleeve moving assembly 501. Then, the nut replacement device 500 continues to move downward and is inserted into the nut placement position 5033. The nut placed in the nut placement position 5033 is inserted into the nut sleeve 502. The nut in the nut sleeve 502 is clamped by the steel ball 5022. Finally, the nut sleeve 502 moves to the bolt of the fixed track 901 under the drive of the sleeve moving assembly 501 and the nut is tightened on the bolt. Furthermore, a nut ejector head 5025 is also provided above the interior of the nut sleeve 502. The nut ejector head 5025 can move axially along the nut sleeve 502. When the nut sleeve 502 holds a bolt removed from the bolt on the fixed track 901, the nut sleeve 502 can move to above the entrance of the box 5031 under the drive of the sleeve moving assembly 501. At this time, the nut ejector head 5025 pushes the bolt inside the nut sleeve 502 into the box 5031, completing the recycling of the old nut. Of course, in some embodiments, the box 5031 includes a new nut storage box and an old nut storage box. The new nut storage box and the old nut storage box are not connected to each other, but the new nut storage box is connected to the nut placement position 5033.

[0047] In some embodiments, after the nut is unscrewed, the nut sleeve 502 moves with the nut to the nut storage box. As the tightening machine 505 continues to descend, the nut sleeve 502 abuts against the nut placement platform 5032. The nut ejector head 5025, located at the end of the tightening machine 505, moves downward relative to the nut sleeve 502, ejecting the nut to the nut placement position 5033. The nut storage box 503 has a forward and reverse function; it receives unloaded nuts when working in reverse and outputs nuts when working in forward. In this embodiment, the nut placement position 5033 is located at the entrance of the box body 5031.

[0048] Combined Figure 2 , Figure 4 , Figure 14 and Figure 15 The track lifting device 700 is installed on the vehicle body 100. It includes a hydraulic lifting assembly 702 and a caliper assembly 701. The hydraulic lifting assembly 702 is installed on the vehicle body and drives the caliper assembly 701 to rise and fall. Figure 15 This is the released state of caliper assembly 701. At this time, the guide post and guide sleeve 7012 inside the caliper spring 7011 are in a locked state (similar to the mechanism in a ballpoint pen that first presses in to lock and then releases when pressed again). The hydraulic cylinder of the hydraulic lifting assembly 702 pushes out, causing the caliper assembly 701 to descend to... Figure 14 In the illustrated state, the caliper assembly 701 contacts the rail 901. The guide post and guide sleeve 7012 within the caliper spring 7011 are triggered, causing the caliper assembly 701 to release. The caliper spring 7011 then presses against the upper and lower rotating shafts, causing the two caliper arms 7013 to hook onto the rail 901. At this time, the cylinder of the hydraulic lifting assembly 702 drives the caliper assembly 701 and the rail 901 to rise, disengaging the rail 901 from the sleeper 903 to facilitate the replacement of the pad 902. After the pad 902 is replaced, the cylinder pushes out again, and the caliper assembly 701 presses down, compressing the caliper spring 7011 while simultaneously locking the guide post and guide sleeve 7012. The caliper arms 7013 release, and the cylinder retracts, thus completing the rail lifting action. The locking structure between the guide sleeve 7012 and the guide post is existing technology and can be implemented using known means; therefore, it is only briefly described.

[0049] Combination Figure 2 and Figure 4A cleaning device 400 is installed on the vehicle body 100. It includes a fan 906 and a nozzle 401 that are connected to each other. The fan 906 provides a high-pressure air source to the nozzle 401, which is located near the caliper assembly 701 and faces downwards from the rail 901. When the rail lifting device 700 lifts the rail 901, the high-pressure air blown out by the nozzle 401 cleans the debris below the rail 901. Specifically, the function of the cleaning device 400 is that when the rail lifting device 700 lifts the rail 901, the detection and analysis system 800 (which may also be a central control system in some embodiments) will start the fan 906. The high-pressure air is blown out through the nozzle 401 to blow away the debris on the upper surface of the rail support groove after the pad 902 has been removed, so that a new pad 902 can be placed.

[0050] Combination Figure 2 and Figure 3 An oil spraying device 600 is installed on the car body 100. It includes an oil spray nozzle 601, which is connected to an oil tank 904 on the car body via an oil pipe. The oil spray nozzle 601 faces the nuts that fix the rail 901. The function of the oil spray nozzle 601 is to spray rust-preventive oil onto the bolts and nuts of the tightened sleepers 903. A high-pressure oil pump sprays the rust-preventive oil from the oil tank 904 through the oil spray nozzle 601 onto the tightened bolts and nuts to prevent them from rusting.

[0051] Combination Figure 2 , Figure 6 as well as Figures 11 to 13The vehicle body 100 is provided with a plate removal groove 305, and a plate removal slider 304 is provided in the plate removal groove 305, which can slide up and down along the plate removal groove 305. The plate removal device 300 is fixed on the plate removal slider 304, and includes a first push plate assembly 301 that can be moved to a first working position to push the pad 902 out from under the track 901 and a pad receiving assembly 302. The first push plate assembly 301 and the pad receiving assembly 302 are arranged opposite to each other in the length direction of the track 901. The first push plate assembly 301 can push the pad 902 to the pad receiving assembly 302. The pad receiving assembly 302 includes a storage box 3022 and a flip plate 3021. The first push plate assembly 301 can push the pad 902 onto the flip plate 3021. The flip plate 3021 can be flipped from the horizontal direction to the vertical direction to a vertical state under the action of the connecting rod 3023, so that the pad 902 is put into the storage box 3022. Specifically, the main function of the plate removal device 300 is to remove the old pad 902 under the track 901. The specific removal steps are as follows: After the first lifting motor 303 receives the command from the control center, the plate removal slider 304 is provided with a threaded hole extending in the vertical direction, and a screw is provided in the threaded hole. The output end of the first lifting motor 303 is connected to one end of the screw. The first lifting motor 303 drives the screw to rotate around its axis, thereby driving the plate removal slider 304 to slide up and down. After the entire plate removal device 300 moves down with the plate removal slider 304 to a suitable height (the top of the push plate 3071 is flush with the top of the pad 902 to be removed and the top of the flip plate 3021), the first left and right moving motor 308 drives the plate removal device 300 to move along the width direction of the track 901 to the bottom of the track 901 through the screw transmission structure, so that the push plate 3071 and the pad 902 to be removed are flush. With the replacement pad 902 opposite, the bottom of the push plate 3071 has a threaded through hole, and a first lead screw 3072 is installed in the threaded through hole. One end of the first lead screw 3072 is connected to the output shaft of the first push plate motor 306. The first push plate motor 306 drives the first lead screw 3072 to rotate in the threaded through hole, thereby driving the push plate 3071 to move and extend towards the old pad 902 along the axial direction of the first lead screw 3072. The push plate 3071 pushes the old pad 902 from under the track 901 onto the flip plate 3021. The push plate 3071 retracts to its original position, and the connecting rod 3023 drives the flip plate 3021 to press the old pad 902 into the storage box 3022 in an upright position. The upright pads 902 are pressed into the storage box 3022 in a row. After the removal is completed, the removal device 300 moves horizontally out from under the track 901 and then moves upward to the original position. At this time, the entire removal action is completed.

[0052] Combination Figure 2 as well as Figures 6 to 10The upper plate device 200 is installed on the car body 100 and its function is to push the pad 902 onto the sleeper 903 at a suitable position. It includes an upper plate box 202 and a second push plate assembly 201 that can be moved to a second working position. The upper plate box 202 is used to store the pad 902. The pad 902 is ejected from the upper plate box to the second push plate assembly 201 through the mechanical structure inside the upper plate box. The second push plate assembly 201 pushes the pad 902 under the track 901. The specific steps for loading the plate are as follows: After receiving instructions from the control center, the second lifting motor 203 moves the entire loading device 200 and the loading slider 204 downwards in the loading groove 205 to a suitable height. Then, the second left and right moving motor 206 drives the second push plate assembly 201 to move along the width direction of the track 901 to a suitable position below the track 901 through the screw and slider cooperation structure. This makes one side of the new pad 902 on the tray 2012 of the second push plate assembly 201 aligned with the original old pad 902. At this time, the second push plate motor 207 starts, and the second screw 208 and the push plate slider 2011 cooperate. The top of the push plate slider 2011 protrudes from the upper surface of the tray 2012. The second screw 208 drives the push plate slider 2011 to push the new pad 902 to a suitable position on the sleeper 903 along the axial direction of the second screw 208. After the above actions are completed, the second pusher motor 207 drives the pusher slider 2011 to return to its original position, and the upper plate box 202 ejects a pad 902 onto the tray 2012. The second left-right moving motor 206 drives the entire upper plate device 200 to move laterally out of the track 901. The second lifting motor 203, through the cooperation of the upper plate slider 204 and the upper plate slide groove 205, drives the entire upper plate device 200 back to the starting position, thus completing one upper plate action. The second pusher motor 207 is the drive mechanism of the upper plate device 200 in this embodiment.
