[0009] Furthermore, the guide rod includes a mounting portion and a sliding portion connected to each other. The sliding portion is located between the first connecting base and the second connecting base and is used to guide the relative movement of the first connecting base and the second connecting base. An adjustment seat is provided on the mounting portion.

[0010] Furthermore, the sliding portion is rotatably connected to the second connecting base at one end away from being connected to the mounting portion.

[0011] Furthermore, a plurality of stop structures arranged at intervals are provided on the mounting portion, and the adjustment seat is provided between any two stop structures, and the stop structures are used to limit the adjustment seat to the mounting portion.

[0012] Furthermore, the stop structure includes raised portions, which are arranged on the mounting portion at intervals, and the adjustment seat is arranged between any two raised portions, and the raised portions are used to limit the adjustment seat on the mounting portion.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] Those skilled in the art will appreciate that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0020] Please refer to the attached Figure 1 To the attached Figure 2 The present invention describes a track shoe disassembly and assembly device.

[0021] This embodiment provides a track shoe disassembly and assembly device, such as Figure 1 As shown, the track plate disassembly and assembly device includes a first connecting base 11 and a second connecting base 12. The first connecting base 11 and the second connecting base 12 are both provided with mounting holes 13. The mounting holes 13 are used to match the positioning points on the track plates so that the first connecting base 11 and the second connecting base 12 can be connected to different track plates. The first connecting base 11 and the second connecting base 12 can be close to each other so that different track plates can be disassembled.

[0022] The track plate disassembly and assembly device can utilize the mounting holes 13 on the first connecting base 11 and the second connecting base 12, and use the prefabricated holes of the track plate as positioning points, match the mounting holes 13 with the positioning points, so that the first connecting base 11 and the second connecting base 12 are connected to the track plate, and then, the track plate is tensioned by bringing the first connecting base 11 and the second connecting base 12 close to each other, thereby removing the track plate pin shaft, thereby completing the disassembly of the track plate. Compared with the traditional chain tensioning method, this structure and disassembly and assembly method not only improves the safety performance and working efficiency, but also can realize standardized track plate disassembly and assembly operations.

[0023] Furthermore, the track shoe assembly and disassembly device further includes a driving member 2, which is connected to the first connecting base 11 or the second connecting base 12, and is used to bring the first connecting base 11 and the second connecting base 12 closer to each other.

[0024] Optionally, the above-mentioned driving member 2 can be a hydraulic jack, and a driving member 2 mounting position is also provided on the first connecting base 11. The body of the hydraulic jack can be set at the above-mentioned mounting position, and the output end extends in a direction away from the second connecting base 12, for driving the first connecting base 11 close to the second connecting base 12. In addition, in some embodiments, the above-mentioned driving member 2 mounting position can also be set on the second connecting base 12, and the second connecting base 12 is driven close to the first connecting base 11. In short, it can be understood that whether the driving member 2 is set on the first connecting base 11 or the second connecting base 12, or whether the above-mentioned driving member 2 mounting position is set, it is only necessary to use the driving member 2 to make the first connecting base 11 and the second connecting base 12 close to each other, and no specific limitation is made here.

[0025] Furthermore, if Figure 1 As shown, the track plate disassembly and assembly device also includes an adjustment mechanism 3, which is slidingly connected to the first connecting base 11 and the second connecting base 12. The adjustment mechanism 3 can be supported on the output end of the driving member 2 to make the first connecting base 11 and the second connecting base 12 close to each other.

[0026] Specifically, by providing the adjustment mechanism 3 , the driving member 2 can output the driving force to the first connecting base 11 or the second connecting base 12 , thereby guiding the first connecting base 11 and the second connecting base 12 to approach each other.

[0027] Furthermore, the adjustment mechanism 3 includes a guide rod 31, on which an adjustment seat 32 is disposed. The guide rod 31 is sequentially inserted through the first connecting base 11 and the second connecting base 12. The output end of the driving member 2 can abut against the adjustment seat 32 to bring the first connecting base 11 and the second connecting base 12 closer to each other. The guide rod 31 can guide the movement direction of the first connecting base 11, thereby causing the first connecting base 11 to approach the second connecting base 12 in a straight line, further ensuring operational efficiency.

[0028] Furthermore, the guide rod 31 includes a mounting portion 311 and a sliding portion 312 connected to each other. The sliding portion 312 is located between the first connecting base 11 and the second connecting base 12 and is used to guide the relative movement of the first connecting base 11 and the second connecting base 12. An adjustment seat 32 is provided on the mounting portion 311.

[0029] Furthermore, the sliding portion 312 is rotatably connected to the second connection base 12 at one end away from the mounting portion 311. Specifically, a lug 121 is provided on the second connection base 12, and a pin hole is provided on the lug 121, and the sliding portion 312 is matched with the pin hole through a pin.

[0030] It should be noted that the distance between the second connecting base 12 and the mounting portion 311 is greater than the distance between the second connecting base 12 and the sliding portion 312, that is, the second connecting base 12 is closer to the sliding portion 312. It can be understood that since the first connecting base 11 and the second connecting base 12 need to overcome greater resistance, the track plates fixedly connected to the first connecting base 11 and the second connecting base 12 are made close to each other. Therefore, the above-mentioned rotating connection setting can enable the two to rotate slightly in the process of approaching each other, thereby achieving a certain buffer, avoiding rigid damage, and ensuring the safety of disassembly.

[0031] Furthermore, if Figure 1 and Figure 2 As shown, the mounting portion 311 is provided with a plurality of spaced apart stop structures 313, and the adjustment seat 32 is disposed between any two of the stop structures 313. The stop structures 313 are used to restrict the adjustment seat 32 to the mounting portion 311. Since the output end of the driver 2 abuts against the adjustment seat 32, the stop structures 313 are provided to prevent the adjustment seat 32 from moving, thereby restricting the adjustment seat 32 to the mounting portion. In addition, multiple stop structures 313 are provided and spaced apart to form multiple mounting positions, allowing personnel to locate the appropriate mounting position according to actual needs.

[0032] In some embodiments, the stop structure 313 includes raised portions 3131, which are spaced apart on the mounting portion 311. The adjustment seat 32 is disposed between any two raised portions 3131. The raised portions 3131 are used to retain the adjustment seat 32 on the mounting portion 311. The raised portions 3131 are used to secure the adjustment seat 32 to the mounting portion 311, thereby ensuring that when the output end of the drive unit abuts against the adjustment seat 32, the first connecting base 11 drives the track shoe to move, and the overall device maintains a certain degree of stability.

[0033] In order to further improve the fastening effect and facilitate the disassembly of the adjustment seat 32, this embodiment provides a stop structure 313 in another form, such as Figure 1 and Figure 2 As shown, the stop structure 313 includes a protrusion 3131 and a stop plate 3132. The protrusion 3131 is arranged at intervals on the mounting portion 311. The stop plate 3132 is provided with a slot. The stop plate 3132 can be arranged between the protrusion 3131 and the adjustment seat 32, and is connected to the mounting portion 311 through the slot. The stop plate 3132 can slide on the mounting portion 311 and respectively abut against the protrusion 3131 and the adjustment seat 32, so that the adjustment seat 32 is limited on the mounting portion 311.

[0034] Furthermore, both the first connecting base 11 and the adjusting base 32 are provided with an inserting hole, which is used to cooperate with the guide rod 31, wherein the specification of the inserting hole is much larger than the specification of the protrusion 3131, so that the guide rod 31 and the protrusion 3131 thereon can be inserted into the inserting hole together, and the size of the slot on the stopper 3132 is generally set to be able to be inserted into the guide rod 31, but the specification of the slot is smaller than the protrusion 3131, so that the stopper 3132 can be snapped into the protrusion to achieve the stopping of the first connecting base 11 and the adjusting base 32. In other words, This structure uses the cooperation of the protrusion 3131 and the stop piece 3132 to stop the first connecting base 11 and the adjustment seat 32, further improving the convenience of the device. Specifically: after the track shoe is disassembled, the stop piece 3132 can be pulled off the guide rod 31, and the adjustment seat 32 can be removed from the mounting portion 311 of the guide rod 31, thereby reducing the overall volume of the device. Alternatively, when actual operations require the disassembly of track shoes of different specifications, the adjustment seat 32 can be set at an installation position between different protrusions 3131 on the mounting portion 311 to ensure the operating effect.

[0035] Optionally, a hook 321 is further provided on the adjustment seat 32 for accommodating a plurality of stop pieces 3132 , and the plurality of stop pieces 3132 can be sequentially hung on the hook 321 .

[0036] It can be understood that the protrusion 3131 is a conical structure.

[0037] Furthermore, a plurality of guide rods 31 are provided, and the plurality of guide rods 31 are arranged in parallel to ensure the stability of the guiding operation. In this embodiment, two guide rods 31 are provided.

[0038] The operation process of the above-mentioned track shoe disassembly and assembly device is as follows: 1. Select the two crawler crane track shoes to be disconnected; 2. Place the first connecting base 11 on the first track shoe, adjust the through hole on the first connecting base 11 to coincide with the prefabricated hole on the track shoe, insert a pin or bolt through the holes on the first connecting base 11 and the prefabricated hole on the track shoe to secure them; place the second connecting base 12 on the other track shoe, adjust the through hole on the second connecting base 12 to coincide with the prefabricated hole on the track shoe, insert a pin or bolt through the holes on the first connecting base 11 and the prefabricated hole on the track shoe to secure them; 3. Install the guide rod 31, passing through the through holes of the first connecting base 11 and the adjusting base 32, and aligning it with the ear plate 121 and the pin hole on the second connecting base 12; 4. Install the driver 2 and the adjustment seat 32, and make the output end of the driver 2 abut against the adjustment seat 32; 5. Install the stopper 3132 on the outside of the first connecting base 11, so that it fits in with the tapered protrusion 3131 and is installed at a position where the mounting portion 311 is closest to the adjustment seat 32. This allows the driver 2 to act directly on the adjustment seat 32 after installation. 6. Start tensioning, activate the drive part 2, and adjust the track shoe installation and removal pin to the appropriate disassembly position. If it is not in place at once, change the position of the adjustment seat 32 until the track shoe pin can be removed. After completion, reverse the above steps to release the track shoe to a relaxed state.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
