[0025] Example 1

[0026] Reference Figure 1-2 , which is the first embodiment of the utility model, and which provides a crawler-type self-moving tail, comprising:

[0027] The vehicle body mechanism 100 includes a vehicle head 101, the inner cavity of the vehicle head 101 is fixedly connected to a connecting frame 301, the end surface of the connecting frame 301 is fixedly connected to a spring 302, and the side surface of the spring 302 is plugged with a rectangular crawler 102;

[0028] In addition, the inner side surface of the rectangular track 102 is clamped with an inner straight plate 303, and the tensioning mechanism 300 where the inner straight plate 303 is located also includes a sliding member 304, and the sliding member 304 is fixedly penetrated through the surface of the rectangular track 102, and the bottom of the connecting frame 301 is fixedly connected to a sheet metal column 402, and the lower surface of the sheet metal column 402 is rotatably connected to an X-shaped connecting rod 401, and the end face of the X-shaped connecting rod 401 is movably plugged into the inner straight plate 303.

[0029] Specifically, the fixed connection between the front of the vehicle 101 and the connecting frame 301 makes the elastic support of the spring 302 on the rectangular track 102 more stable, and also provides a stable platform for the elastic tensioning of the rectangular track 102. The cooperation between the inner straight plate 303 and the sliding member 304 ensures that the rectangular track 102 is stably supported by the inner straight plate 303 when tensioned, thereby avoiding the occurrence of breakage and distortion of the rectangular track 102, indirectly increasing the service life of the rectangular track 102 and better meeting the transportation requirements of engineering equipment. The connection between the X-shaped connecting rod 401 and the inner straight plate 303 is conducive to ensuring the structural integrity of the inner straight plate 303 and avoiding stress extrusion of the rectangular track 102.

[0030] Furthermore, the sliding member 304 includes a guide column 304a fixedly connected to the upper surface of the inner straight plate 303, the upper surface of the guide column 304a is plugged with a pillow block 304b, the upper surface of the pillow block 304b is slidably connected with a square frame 304c, the upper surface of the square frame 304c is fixedly connected to the lower surface of the inner cavity of the car head 101, and the side of the square frame 304c is adapted to be installed with a triangle plate 305.

[0031] Preferably, the plug-in connection between the guide column 304a and the pillow block 304b allows the X-shaped connecting rod 401 to move, thereby providing support for the rectangular track 102 at different positions, improving the stable transportation effect of the rectangular track 102, thereby eliminating the tedious use of track extensions and saving the use of track materials.

[0032] When in use, first assemble the connecting frame 301 on the inner surface of the front part 101, then fix the spring 302 on the end surface of the connecting frame 301, and then plug and connect the rectangular track 102 on the end surface of the spring 302, the inner straight plate 303 is in close contact with the inner surface of the rectangular track 102, and then the sheet metal column 402 is plugged and installed on the bottom of the connecting frame 301 in the sliding part 304, and the X-shaped connecting rod 401 is rotatably installed on the lower surface of the sheet metal column 402 for tensioning and adjusting the inner surface of the rectangular track 102.

[0033] In summary, through the fixed connection between the front of the vehicle 101 and the connecting frame 301, the elastic support of the spring 302 to the rectangular track 102 is more stable, and a stable platform is provided for the elastic tensioning of the rectangular track 102. The cooperation between the inner straight plate 303 and the sliding member 304 enables the rectangular track 102 to be stably supported by the inner straight plate 303 when tensioned, thereby avoiding the occurrence of breakage and distortion of the rectangular track 102, indirectly increasing the service life of the rectangular track 102 and better meeting the transportation needs of engineering equipment. The connection between the X-shaped connecting rod 401 and the inner straight plate 303 is conducive to ensuring the structural integrity of the inner straight plate 303 and avoiding stress extrusion of the rectangular track 102.

[0034] Example 2

[0035] Reference Figure 2-3 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides relevant parts for realizing the rotation support effect of the inner straight plate 303.

[0037] Furthermore, the rotating sleeve of the triangular plate 305 and the swing arm 306 supports the rotational movement of the swing arm 306 firmly, and the meshing of the gear 308 and the rack 307 can transmit the torque to the L-shaped side frame 309, so that the L-shaped side frame 309 can adjust the pillow block 304b more directly.

[0038] Preferably, a support rod 310 is fixedly sleeved at the bottom of the through shaft 311 , and an end surface of the support rod 310 is fixedly connected to the lower surface of the connecting frame 301 .

[0039] The fixed sleeve arrangement of the support rod 310 and the through shaft 311 ensures the stable support of the through shaft 311 and indirectly improves the meshing efficiency of the gear 308 connected to the through shaft 311.

[0040] Afterwards, the number of the X-shaped connecting rods 401 is two, and the two X-shaped connecting rods 401 are symmetrically arranged on the inner side of the inner straight plate 303 .

[0041] In the above, the symmetrical arrangement of the two X-shaped links 401 is conducive to providing a more balanced support effect for the rectangular track 102, helping the rectangular track 102 to meet transportation needs in different occasions and avoiding the waste of track materials caused by the use of extension parts.

[0042] When in use, firstly, the two X-shaped connecting rods 401 are symmetrically arranged on the inner side surface of the inner straight plate 303, and then the support rod 310 is fixedly mounted on the bottom of the through shaft 311.

Then, the through shaft 311 and the L-shaped side frame 309 are sequentially adapted and installed at the bottom of the gear 308 for the meshing of the gear 308 and the rack 307.

[0043] In summary, through the rotational sleeve of the triangular plate 305 and the swing arm 306, the rotational movement of the swing arm 306 is supported and stabilized, and the engagement of the gear 308 and the rack 307 can transmit the torque to the L-shaped side frame 309, and the L-shaped side frame 309 can adjust the pillow block 304b more directly.

[0044] Example 3

[0045] Reference Figure 2-4 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides relevant parts for realizing stable operation of the vehicle head 101.

[0046] Specifically, the L-shaped side frame 309 is an integrally formed rubber curved rod, and the end surface of the L-shaped side frame 309 is rotatably connected to the inner straight plate 303 through a pin shaft, and the angle of the L-shaped side frame 309 is a right angle.

[0047] Furthermore, the L-shaped side frame 309 is rotatably connected to the inner straight plate 303 so that the rotational motion is transmitted. Meanwhile, the L-shaped side frame 309 is a right-angled rubber bent rod, which can ensure that the L-shaped side frame 309 maintains structural integrity when subjected to stress.

[0048] Preferably, the front of the vehicle 101 is provided with a displacement mechanism 200 , and the displacement mechanism 200 includes a roller 201 fixedly connected to the bottom of the front of the vehicle 101 , and a slide rail 202 is slidably connected to the lower surface of the roller 201 .

[0049] The sliding cooperation between the roller 201 and the slide rail 202 enables the front of the vehicle 101 to have basic operating capabilities, and the rectangular track 102 can help the front of the vehicle 101 stabilize the rear.

[0050] When in use, firstly, the L-shaped side frame 309 is rotatably connected to the inner straight plate 303 , and then the roller 201 is adapted to be installed at the bottom of the headstock 101 , and the roller 201 and the slide rail 202 are allowed to slide, so as to ensure the stable operation of the headstock 101 .

[0051] In summary, the rotational motion is transmitted through the rotational connection between the L-shaped side frame 309 and the inner straight plate 303, and at the same time, the L-shaped side frame 309 is a right-angle rubber bent rod setting, which can ensure that the L-shaped side frame 309 maintains structural integrity when subjected to force.
