Abstract
Description
Technical Field
[0001] This utility model relates to the field of track maintenance technology, and in particular to a quick fixing device for track maintenance. Background Technology
[0002] A caterpillar track (or continuous track) is a ring-shaped transmission device consisting of a series of rigid or semi-rigid connecting units (usually called track plates or track links). It is widely used in engineering machinery, military vehicles, and agricultural machinery. Its core function is to convert engine power into traction through the contact between the track and the ground, enabling vehicles to move efficiently on complex terrains such as mud, sand, snow, or rough roads.
[0003] Since tracks are often used in work scenarios with complex road conditions, they suffer from significant wear and tear. Damage to tracks severely affects the operation of mechanical equipment. Therefore, a device is needed that can quickly clamp the tracks for easy maintenance. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a quick-fixing device for track maintenance. The device utilizes the weight of the track to drive two clamping mechanisms to move inward along a transverse guide rod. The two clamping mechanisms convert the weight of the track into a clamping force, automatically clamping the track on the clamping mechanism. This greatly improves clamping efficiency and is a simple, efficient, safe, reliable, and easy-to-operate quick-fixing device for track maintenance.
[0005] This utility model is achieved through the following technical solution: a quick-fixing device for track maintenance is provided, including a workbench; the workbench is provided with one or more clamping mechanisms, each clamping mechanism including two opposing clamping plates and a transverse guide rod that slides through the two clamping plates. A connecting rod is provided between the clamping plates and the workbench, one end of the connecting rod is hinged to the bottom of the clamping plate and converges inward, and the other end of the connecting rod is hinged to the workbench and expands outward. The weight of the track drives the two clamping mechanisms to move inward along the transverse guide rod. The two clamping mechanisms convert the weight of the track into a clamping force on the track, automatically completing the clamping of the track on the clamping mechanism, greatly improving clamping efficiency.
[0006] As an optimization, a longitudinal guide rod extending vertically is fixed on the transverse guide rod, and a through hole adapted to the longitudinal guide rod is opened on the worktable, through which the longitudinal guide rod slides. The longitudinal guide rod and the through hole ensure that the two clamping mechanisms move synchronously in the vertical direction, preventing the clamping mechanisms from tilting and improving clamping efficiency.
[0007] As an optimization, a return spring A is provided on the outer sleeve of the longitudinal guide rod; the return spring A keeps the transverse guide rod at a certain height, thereby keeping a certain distance between the two clamping mechanisms in the idle state, thus improving the clamping efficiency.
[0008] As an optimization, the connecting rod is connected to the worktable via a sliding mechanism. The sliding mechanism includes a slider, a slide rod, a return spring B, and an adjustment table. A sliding limit groove is opened on the adjustment table, the slide rod is located in the sliding limit groove, the slider is slidably mounted on the slide rod, the return spring B is located between the slider and the inner wall of the sliding limit groove, and the bottom of the connecting rod is connected to the slider. By changing the tilt angle of the connecting rod through the slider and the slide rod, more track weight is converted into clamping force on the track, thereby increasing the clamping force of the clamping mechanism on the track.
[0009] As an optimization, a lateral sliding groove is provided on the worktable, and an adjustment table is located in the sliding groove. The worktable is provided with a drive mechanism A for driving the adjustment table to slide along the sliding groove. The distance between the two sliders is adjusted by the drive mechanism A and the adjustment table, thereby clamping tracks of different sizes.
[0010] As an optimization, a feeding mechanism is provided above the clamping mechanism. The feeding mechanism includes a slide rail fixed on the worktable and extending vertically. A bracket is slidably mounted on the slide rail, and rollers are mounted on the bracket. The bracket is driven to slide vertically by the drive mechanism B, which facilitates the insertion and removal of the track. The rollers facilitate pulling the track on the bracket.
[0011] As an optimization, a drive mechanism C for driving the rollers to rotate is fixed on the support; the tracks are pulled by the drive mechanism C and the rollers, saving manpower.
[0012] As an optimization, the clamping plate includes a load-bearing plate and a clamping plate. The load-bearing plate is set horizontally, and the clamping plate is set vertically. Perforations are made on the load-bearing plate to facilitate clamping the track.
[0013] The beneficial effects of this utility model are as follows: the weight of the track drives the two clamping mechanisms to move inward along the transverse guide rod, and the two clamping mechanisms convert the weight of the track into a clamping force on the track, automatically completing the clamping of the track on the clamping mechanism, greatly improving the clamping efficiency; the longitudinal guide rod and through hole ensure that the two clamping mechanisms move synchronously in the vertical direction, preventing the clamping mechanism from tilting and improving the clamping efficiency; the return spring A keeps the transverse guide rod at a certain height, so that the two clamping mechanisms in the idle state maintain a certain distance, thereby improving the clamping efficiency; the slider and slide rod change the tilt angle of the connecting rod, thereby converting more track weight into a clamping force on the track, thereby increasing the clamping force of the clamping mechanism on the track; the drive mechanism A and the adjustment table adjust the distance between the two sliders, thereby clamping tracks of different sizes; the drive mechanism B drives the bracket to slide in the vertical direction, which facilitates the insertion and removal of the track.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0019] like Figures 1-3 As shown, the quick-fixing device for track maintenance of this utility model includes a workbench 1. The workbench 1 is provided with two sets of clamping mechanisms. Each set of clamping mechanisms includes two L-shaped clamping pieces arranged opposite each other. The workbench 1 is hinged to the two L-shaped clamping pieces by two connecting rods 2 arranged opposite each other. The connecting rods 2 are inclined between the workbench 1 and the clamping mechanism 301, that is, the ends of the two connecting rods 2 away from the workbench 1 are close to each other, and the ends connected to the workbench 1 are far from each other. The clamping mechanism 3 has a through hole extending laterally, and a transverse guide rod 4 slides through the through hole.
[0020] The clamping mechanism 3 includes a load-bearing plate 301 and a clamping plate 302. The load-bearing plate 301 extends inward in the horizontal direction, and the clamping plate 302 extends upward in the vertical direction. The connecting rods 2 are arranged in sequence along the longitudinal direction, and the two ends of the connecting rods 2 are respectively hinged to the worktable 1 and the clamping mechanism 3.
[0021] When clamping the track, first pull the clamping mechanism 3. The two clamping mechanisms 3 move in opposite directions on the transverse guide rod 4 until the distance between the two clamping mechanisms 3 increases to a certain extent. Place both sides of the track on the two clamping mechanisms 3 respectively. Under the action of the track's gravity, the two clamping mechanisms 3 move towards each other on the transverse guide rod 4. At the same time, the connecting rod 2 rotates on the worktable 1 until the two clamping mechanisms 3 complete the clamping work on the track.
[0022] like Figure 1 and Figure 2 As shown, a longitudinal guide rod 5 extending vertically is fixed on the transverse guide rod 4, and a through hole adapted to the longitudinal guide rod 5 is opened on the worktable 1, with the longitudinal guide rod 5 slidingly passing through the through hole.
[0023] Pull the clamping mechanism 3, and the connecting rod 2 rotates on the worktable 1. The two clamping mechanisms 3 move in opposite directions on the transverse guide rod 4 and drive the longitudinal guide rod 5 to slide upward in the through hole until the distance between the two clamping mechanisms 3 increases to a certain extent. Place both sides of the track on the two clamping mechanisms 3 respectively. Under the action of the track's gravity, the two clamping mechanisms 3 move downward and drive the longitudinal guide rod 5 to slide downward in the through hole through the transverse guide rod 4. The two clamping mechanisms 3 move towards each other on the transverse guide rod 4. The connecting rod 2 rotates on the worktable 1 and converts part of the track's gravity into a clamping force on the track until the two clamping mechanisms 3 complete the clamping work on the track.
[0024] like Figure 1 and Figure 2 As shown, the end of the longitudinal guide rod 5 away from the transverse guide rod 4 passes through the reset spring A6 and slides through the through hole.
[0025] The two sides of the track are placed on the two clamping mechanisms 3 respectively. Under the action of the track's gravity, the two clamping mechanisms 3 move downward and drive the longitudinal guide rod 5 to slide downward in the through hole through the transverse guide rod 4. The return spring A6 contracts, and the connecting rod 2 rotates on the worktable 1, converting part of the track's gravity into a clamping force on the track. The two clamping mechanisms 3 move towards each other on the transverse guide rod 4 until the two clamping mechanisms 3 complete the clamping work on the track. After the track maintenance work is completed and the track is removed, the return spring A6 relaxes, the longitudinal guide rod 5 slides upward in the through hole and drives the two clamping mechanisms 3 to move upward through the transverse guide rod 4. The two clamping mechanisms 3 move away from each other on the transverse guide rod 4, and the connecting rod 2 rotates on the worktable 1 until the return spring A6 fully relaxes and the distance between the two clamping mechanisms 3 returns to its original position.
[0026] like Figures 1-3 As shown, the worktable 1 is provided with a slide bar 7 extending laterally, and a slider 8 is slidably mounted on the slide bar 7. The slider 8 is connected to the worktable 1 through a return spring B9 sleeved on the slide bar 7. The end of the connecting rod 2 away from the clamping mechanism 3 is hinged to the slider 8, and the two clamping mechanisms 3 are located between the two sliders 8.
[0027] The two sides of the track are placed on the two clamping mechanisms 3 respectively. Under the action of the track's weight, the two clamping mechanisms 3 move downwards. The connecting rod 2 rotates on the worktable 1 and converts part of the track's weight into a clamping force on the track. The two clamping mechanisms 3 move towards each other on the transverse guide rod 4. At the same time, the clamping mechanisms 3 transmit pressure to the sliders 8 through the connecting rod 2. The two sliders 8 move away from each other on the slide rod 7. At the same time, the return spring B9 contracts and applies a certain pushing force to the sliders 8. The tilt angle of the connecting rod 2 gradually increases until the supporting force applied by the sliders 8 to the clamping mechanisms 3 through the connecting rod 2 is the same as the weight of the track. The sliders 8, connecting rod 2 and clamping mechanisms 3 stop sliding, and the two clamping mechanisms 3 complete the clamping work on the track. After the track maintenance work is completed and the track is removed, the return spring B9 relaxes. Under the action of the return spring B9, the sliders 8 move towards each other on the slide rod 7. The connecting rod 2 rotates on the worktable 1 and drives the two clamping mechanisms 3 to move away from each other on the transverse guide rod 4.
[0028] like Figures 1-3 As shown, the worktable 1 has a horizontally extending slide groove 101, and an adjusting table 10 is slidably arranged in the slide groove 101. The worktable 1 has a drive mechanism A11 that drives the adjusting table 10 to move in the opposite direction along the slide groove 101. The adjusting table 10 has a sliding limit groove, the slide rod 7 is located in the sliding limit groove 10, and the two sliders 8 are respectively slidably arranged on the corresponding adjusting table 10. The two sliders 8 are respectively connected to the corresponding adjusting table 10 through a return spring B9.
[0029] The drive mechanism A11 includes a screw A1101 extending laterally. The adjustment table 10 has a screw hole A that matches the screw A1101. The screw A1101 is rotated in the screw hole A. The two adjustment tables 10 are located at the two ends of the screw A1101, and the threads at the two ends of the screw A1101 are arranged opposite each other. A rocker handle 1102 is fixed on the screw A1101.
[0030] When the drive mechanism A11 is activated, the two adjustment platforms 10 drive the slider 8 to move in the opposite direction. The slider 8 drives the two clamping mechanisms 3 to move in the opposite direction on the transverse guide rod 4 through the connecting rod 2, and the distance between the two clamping mechanisms 3 changes.
[0031] like Figures 1-3 The workbench 1 shown is fixed with a slide rail 12 extending in the vertical direction, and a bracket 13 arranged in the horizontal direction slides on the slide rail 12. The workbench 1 is fixed with a drive mechanism B14 that drives the bracket 13 to move along the slide rail 12.
[0032] The drive mechanism B14 includes a screw B1401 that is mounted on the worktable 1 and extends vertically. The bracket 13 has a screw hole B that is adapted to the screw B1401. The screw B1401 is mounted in the screw hole B. The worktable 1 is fixed with a motor A1402 that drives the screw B1401 to rotate.
[0033] Place the track on the bracket 13, start the drive mechanism B14. The drive mechanism B14 drives the bracket 13 to move vertically downward on the slide rail 12. The track enters between the two clamping mechanisms 3 and drives the clamping mechanisms 3 to move downward until the two clamping mechanisms 3 have finished clamping the track. Then, turn off the drive mechanism B14. After the track maintenance is completed, start the drive mechanism B14. The drive mechanism B14 drives the bracket 13 to move vertically upward on the slide rail 12. The clamping mechanisms 3 move upward with the track until the track is completely disengaged from the clamping mechanisms 3. Then, turn off the drive mechanism B14.
[0034] like Figures 1-3 The worktable 1 shown is provided with several rollers 15 whose rotation axes extend laterally; the rollers 15 are arranged in sequence along the longitudinal direction, and the rollers 15 and the clamping mechanism 3 are arranged alternately in the longitudinal direction.
[0035] Pull the track, and the track will roll on the roller 15 until the track is pulled to the designated position.
[0036] like Figures 1-3 The bracket 13 shown is fixedly provided with a drive mechanism C16 for driving the roller 15 to rotate; the drive mechanism C16 includes a motor B, and the output end of the motor B is coaxially fixedly connected to any roller 15.
[0037] Start the drive mechanism C16. The drive mechanism C16 drives the roller 15 to rotate. The track moves on the bracket 13 under the pull of the roller 15 until the track moves to the designated position. Then, turn off the drive mechanism C16.
[0038] In actual production, the drive mechanism A11 is started, and the two adjustment platforms 10 drive the slider 8 to move in the opposite direction. The slider 8 drives the two clamping mechanisms 3 to move in the opposite direction on the transverse guide rod 4 through the connecting rod 2. The distance between the two clamping mechanisms 3 gradually changes until the distance between the two clamping mechanisms 3 matches the size of the track. Then the drive mechanism A11 is turned off.
[0039] Start drive mechanism C16, which drives roller 15 to rotate. The track moves on bracket 13 under the pull of roller 15 until the track moves to the designated position. Then, turn off drive mechanism C16. Place the track on bracket 13 and start drive mechanism B14. Drive mechanism B14 drives bracket 13 to move vertically downward on slide rail 12. The track enters between the two clamping mechanisms 3 and drives the clamping mechanisms 3 to move downward. The clamping mechanisms 3 drive the longitudinal guide rod 5 to slide downward in the through hole through the transverse guide rod 4. The return spring A6 returns to its original position. The connecting rod 2 rotates on the worktable 1 and converts part of the track's weight into a clamping force on the track. The two clamping mechanisms 3 move towards each other on the transverse guide rod 4. At the same time, the clamping mechanism 3 transmits pressure to the slider 8 through the connecting rod 2. The two sliders 8 move away from each other on the slide rod 7. Meanwhile, the return spring B9 contracts and applies a certain pushing force to the slider 8. The tilt angle of the connecting rod 2 gradually increases until the supporting force applied by the slider 8 to the clamping mechanism 3 through the connecting rod 2 is the same as the weight of the track. The slider 8, connecting rod 2, and clamping mechanism 3 stop sliding, and the two clamping mechanisms 3 complete the clamping work on the track. The drive mechanism B14 is turned off.
[0040] After completing track maintenance, start drive mechanism B14. Drive mechanism B14 drives bracket 13 to move vertically upward on slide rail 12, and bracket 13 drives track to move vertically upward. Return springs A6 and B9 relax, and slider 8 moves towards each other on slide rod 7 under the action of return spring B9. Connecting rod 2 rotates on worktable 1 and drives two clamping mechanisms 3 to move in opposite directions on transverse guide rod 4. At the same time, longitudinal guide rod 5 slides upward in through hole and drives two clamping mechanisms 3 to move upward through transverse guide rod 4. The two clamping mechanisms 3 move in opposite directions on transverse guide rod 4 until track is completely disengaged from clamping mechanism 3, return springs A6 and B9 fully relax, and the distance between the two clamping mechanisms 3 returns to its original position. Then, turn off drive mechanism B14.
