Description

Technical Field

[0001] This utility model relates to the field of excavator track assembly technology, and in particular to an excavator track assembly centering device. Background Technology

[0002] Tracks are flexible chains driven by a drive sprocket and surrounding the drive sprocket, road wheel, idler wheel, and track support roller. They are mainly composed of track plates and track pins and are commonly used in heavy machinery such as tanks or excavators. They are divided into all-metal tracks and rubber-coated tracks. The latter has vulcanized rubber blocks added to both sides of the metal track to reduce damage to the road surface.

[0003] Patent publication number CN212763181U discloses an excavator track mounting structure, including track plates and a fixing plate. A pair of pins are fixedly connected to one side surface of the fixing plate. One end of each pin is fitted with a pin sleeve. Two threaded sleeves are rotatably fitted inside the pin sleeve. One end of each pin has a threaded portion, and the pin end is threadedly connected to the inside of the threaded sleeve through the threaded portion. A gear disc is rotatably connected inside the pin sleeve between the two threaded sleeves. Rotating a spline block allows for a quick and easy connection between the pin sleeve and the pin end, requiring no forceful hammering. The meshing connection design between the spline block and the spline groove effectively limits the rotation of the gear shaft, thus limiting the connection between the pin sleeve and the pin. This facilitates quick track plate installation while ensuring installation stability between the track plates.

[0004] The above devices improve the convenience of track installation, but the overall installation process is still similar to the traditional installation process. The installation process is mainly manual, requiring manual operation or the use of tools. The installation process is relatively labor-intensive. In addition, since excavators are large mechanical equipment, and manual installation at close range requires the use of tools such as crowbars for auxiliary centering, there are also safety issues. Therefore, an excavator track assembly and centering device is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an excavator track assembly and alignment device.

[0006] The excavator track assembly and alignment device provided by this utility model adopts the following technical solution:

[0007] An excavator track assembly and alignment device includes a base plate, a pushing mechanism is provided on the top of the base plate, two base frames are fixedly connected to the top of the base plate, and a correction component is provided on the base frames;

The track frames are located on both sides of the dual-axis drive motors. Two sprockets are rotatably connected inside the track frames. A chain is provided inside the track frames. A movable seat is slidably connected to the top of the track frames. A support plate is fixedly connected to the top of the movable seat.

[0010] By adopting the above technical solution, the two drive wheels of the excavator to be assembled are positioned between two dual-shaft drive motors. Then, the tracks are suspended on push rods. After the dual-shaft drive motors are activated, they drive the sprockets to rotate, which in turn drives the chain to rotate, eventually causing the moving seat to move. At this point, the push rods drive the tracks toward the excavator's drive wheels. Once the tracks have rotated to the outside of the drive wheels, the excavator's drive wheels are controlled to rotate, which in turn drives the tracks to rotate. During this rotation, the pry bar is controlled to pry the tracks, causing the meshing part at the center of the tracks to align with the meshing position on the drive wheels. This allows for rapid alignment and assembly, which is more labor-saving and safer than manual assembly.

Two rectangular plates are integrally formed on one side of the socket, and a first gear is rotatably connected between the two rectangular plates. The first gear meshes with the toothed grooves. A first motor is fixedly connected to one side of one of the rectangular plates, and the first motor is fixedly connected to the first gear through an output shaft.

[0014] By adopting the above technical solution, after the first motor works, it drives the first gear to rotate. Since the first gear meshes with the tooth groove, the control lever can be moved when the first gear rotates.

[0015] Preferably, the control rod has a limiting groove, and the inner wall of the socket extends into the limiting groove and matches the limiting groove.

A third gear is fixedly connected to the outside of the connecting rod, and the second gear is located on one side of the third gear and meshes with the third gear.

[0018] By adopting the above technical solution, after the second motor starts working, it drives the second gear to rotate, which in turn causes the second gear to drive the third gear to rotate.

[0019] Preferably, a third motor is fixedly connected to the top wall of the track frame, and a threaded adjusting rod is rotatably connected inside the track frame. The threaded adjusting rod passes through the moving block and is connected to the moving block by a thread.

[0026] By adopting the above technical solution, during the movement of the movable plate, the rotation of the rack and the fourth gear causes the fourth gear to drive the rotation of the rotary table.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The present invention will be described in further detail below.

Figures 1-7 It includes a base plate 1, a pushing mechanism 2 is provided on the top of the base plate 1, two base frames 3 are fixedly connected to the top of the base plate 1, and a correction component 4 is provided on the base frames 3;

[0042] The pushing mechanism 2 includes two dual-axis drive motors 21, both of which are fixedly connected to the top of the base plate 1. Four track frames 22 are provided on the top of the base plate 1. The dual-axis drive motors 21 and the track frames 22 are distributed in a mirror image symmetrically on the left and right sides of the base plate 1. The track frames 22 are located on both sides of the dual-axis drive motors 21. Two sprockets 23 are rotatably connected inside the track frames 22. A chain 24 is provided inside the track frames 22. A movable seat 25 is slidably connected to the top of the track frames 22. A support plate 26 is fixedly connected to the top of the movable seat 25. Push rods 27 are provided on both sides of the dual-axis drive motors 21. One end of two adjacent support plates 26 is fixedly connected to the outside of one of the push rods 27.

[0043] The correction component 4 includes a movable block 41, which is slidably connected to the inside of the base frame 3. A rotating platform 42 is rotatably connected to the top of the movable block 41. A robotic arm device 43 is fixedly connected to the top of the rotating platform 42. A socket 44 is provided at one end of the robotic arm device 43. A connecting rod 45 is fixedly connected to one side of the socket 44. The connecting rod 45 extends into the inside of the robotic arm device 43 and is fixedly connected to the robotic arm device 43. A control rod 46 is provided on one side of the robotic arm device 43.

[0044] The control lever 46 passes through and matches the socket 44. One end of the control lever 46 is rotatably connected to the pry bar 47. The two drive wheels of the excavator to be assembled are positioned between the two dual-shaft drive motors 21. Then, the track is suspended on the push rod 27. After the dual-shaft drive motors 21 are turned on, they drive the sprocket 23 to rotate, which in turn drives the chain 24 to rotate. Finally, the moving seat 25 moves. At this time, the push rod 27 drives the track to move towards the drive wheel of the excavator. When the track moves to the outside of the drive wheel and rotates, the drive wheel of the excavator is controlled to rotate to drive the track to rotate. During the rotation, the pry bar 47 is controlled to pry the track so that the meshing part at the center of the track is aligned with the meshing position on the drive wheel. This allows for quick centering and assembly, which is more labor-saving and safer than manual assembly.

[0045] Two dual-axis drive motors 21 are disposed between two base frames 3. The two ends of the chain 24 are fixedly connected to the two sides of the movable seat 25 respectively. A first transmission rod 28 is disposed between adjacent track frames 22. The two sides of the dual-axis drive motors 21 are fixedly connected to the second transmission rods 29 through the output shaft. The chain 24 is disposed outside the sprocket 23 and meshes with the sprocket 23. One end of the first transmission rod 28 and the second transmission rod 29 are fixedly connected to one of the sprockets 23 in the track frame 22. After the dual-axis drive motors 21 work, they drive the two connected second transmission rods 29 to rotate, which in turn drives the sprocket 23 to rotate, thereby driving the movable seat 25 to move horizontally.

[0046] The control lever 46 has a toothed groove 48, which is evenly spaced on the control lever 46. The socket 44 has two rectangular plates integrally formed on one side, and a first gear 49 is rotatably connected between the two rectangular plates. The first gear 49 meshes with the toothed groove 48. A first motor 491 is fixedly connected to one side of one of the rectangular plates. The first motor 491 is fixedly connected to the first gear 49 through an output shaft. After the first motor 491 works, it drives the first gear 49 to rotate. Since the first gear 49 meshes with the toothed groove 48, the rotation of the first gear 49 can drive the control lever 46 to move.

[0047] The control lever 46 has a limiting groove 492. The inner wall of the socket 44 extends into the limiting groove 492 and matches it. The extension of the socket 44 into the limiting groove 492 can improve the stability of the control lever 46 when it moves. The mechanical arm device 43 is fixedly connected to a second motor 493. The second motor 493 is fixedly connected to a second gear 494 through an output shaft. The connecting rod 45 is fixedly connected to a third gear 495. The second gear 494 is located on one side of the third gear 495 and meshes with the third gear 495. After the second motor 493 works, it drives the second gear 494 to rotate, which in turn causes the second gear 494 to drive the third gear 495 to rotate.

[0048] A third motor 496 is fixedly connected to the top wall of the track frame 22. A threaded adjusting rod 497 is rotatably connected inside the track frame 22. The threaded adjusting rod 497 passes through the moving block 41 and is threadedly connected to the moving block 41. After the third motor 496 works, it drives the threaded adjusting rod 497 to rotate. The threaded adjusting rod 497 drives the moving block 41 to move horizontally inside the track frame 22. The third motor 496 is fixedly connected to a first bevel gear 498 through its output shaft. A second bevel gear 499 is fixedly connected to the outside of the threaded adjusting rod 497. The first bevel gear 498 is located on top of the second bevel gear 499 and meshes with the second bevel gear 499. After the first motor 491 works, it drives the first bevel gear 498 to rotate. The first bevel gear 498 drives the second bevel gear 499 to rotate, thereby realizing the rotation of the threaded adjusting rod 497.

[0049] A guide plate 481 is fixedly connected inside the movable block 41, and a movable plate 482 is slidably connected outside the guide plate 481. A fourth gear 483 is fixedly connected outside the rotary table 42. The fourth gear 483 is located inside the movable block 41. The movable plate 482 can move flexibly outside the guide plate 481. A rack 484 is fixedly connected outside the movable plate 482. The rack 484 is located on one side of the fourth gear 483 and meshes with the fourth gear 483. During the movement of the movable plate 482, the rack 484 and the fourth gear 483 rotate, thereby enabling the fourth gear 483 to drive the rotary table 42 to rotate. An electric push rod 485 is fixedly connected inside the guide plate 481. One end of the electric push rod 485 is fixedly connected to the movable plate 482. After the electric push rod 485 is working, it drives the movable plate 482 to move horizontally.

[0050] In actual operation, when this device is used, first connect the power supply to the device, place the two drive wheels of the excavator to be assembled between the two dual-shaft drive motors 21, and then suspend the track on the push rod 27. After the dual-shaft drive motor 21 works, it drives the two connected second transmission rods 29 to rotate. The second transmission rods 29 drive the connected sprockets 23 to rotate. The sprockets 23 drive the connected first transmission rod 28 to rotate. The first transmission rod 28 drives the sprocket 23 inside the outermost track frame 22 to rotate. Then the sprocket 23 drives the chain 24 to rotate. During the rotation of the chain 24, it pulls the moving seat 25, thereby realizing the horizontal movement of the moving seat 25. After the moving seat 25 moves, it drives the support plate 26 to move. The support plate 26 drives the push rod 27 to move, thereby realizing the purpose of pushing the track and pushing the track to the outside of the excavator's drive wheel.

[0051] When the tracks move to the outside of the drive wheel and rotate, the drive wheel of the excavator is controlled to rotate to drive the tracks to rotate. At the same time, the third motor 496 works and drives the first bevel gear 498 to rotate. The first bevel gear 498 drives the second bevel gear 499 to rotate. The second bevel gear 499 drives the threaded adjusting rod 497 to rotate. The threaded adjusting rod 497 drives the moving block 41 to move horizontally. The moving block 41 drives the rotating table 42 to move. After the rotating table 42 drives the robotic arm device 43 to the prying position, the electric push rod 485 works and pushes the movable plate 482. The movable plate 482 drives the rack 484 to move. The rack 484 drives the fourth gear 483 to rotate. After the fourth gear 483 rotates, it drives the rotating table 42 to rotate. The rotating table 42 drives the robotic arm to rotate to the operating position.

[0052] After the orientation adjustment is completed, the first motor 491 operates and drives the first gear 49 to rotate. Since the first gear 49 meshes with the tooth groove 48 on the control rod 46, the first gear 49 drives the control rod 46 to move. During the movement of the control rod 46, its distance extending towards the track can be adjusted. Meanwhile, the second motor 493 operates and drives the second gear 494 to rotate. The second gear 494 drives the third gear 495 to rotate. The third gear 495 drives the connecting rod 45 to rotate. The connecting rod 45 drives the socket 44 to rotate. At this time, the socket 44 drives the control rod 46 to engage. The connecting rod 45 rotates around its axis, and the angle of the control rod 46 is adjusted during the rotation. Based on the above steps, the control rod 46 can be quickly adjusted. When the control rod 46 extends towards the track to perform a prying operation, the pry bar 47 contacts the inner surface of the track. The advantage of the pry bar 47 contacting the track is that during the track being pried and corrected, the pry bar 47 can cooperate with the track rotation by rotating on its own, maintaining the stability of the prying process until the meshing part at the center of the track is aligned with the meshing position on the drive wheel, thus completing the entire alignment and assembly process. Compared with manual assembly, this method saves more manpower and is safer.

[0053] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
