DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 , Figure 1 This is a schematic diagram of the overall structure of the walking type self-moving equipment train provided by the utility model; Figure 2 A schematic diagram of the structure of the support assembly provided by the utility model; Figure 2 A schematic structural diagram of the auxiliary support mechanism provided by the present invention; Figure 4 A schematic diagram of the structure of the restriction component provided by the utility model; Figure 5 This is a schematic diagram of the disassembled structure of the restriction component provided by the utility model.

[0025] In the specific implementation process, Figures 1 to 5 As shown, the walking self-propelled equipment train provided by the present invention includes a car body 1, two sets of support fixing seats 2 are fixedly connected to the bottom of the car body 1, and auxiliary support mechanisms 4 are threadedly connected to the support fixing seats 2 via bolts 3. The bottom of the car body 1 is also provided with a limiting component located outside the auxiliary support mechanism 4, and a support component is installed at the bottom of one set of auxiliary support mechanisms 4;

[0026] The support assembly includes a load-bearing base frame 5, to which a main support frame 6 and two side support frames 7 are fixedly connected. A plurality of reinforcing ribs 8 are arranged between the two ends of the main support frame 6 and the load-bearing base frame 5. The top of the side support frame 7 is fixedly connected to the auxiliary support mechanism 4. The cross-section of the side support frame 7 is trapezoidal. The support assembly is made of alloy steel material with higher tensile strength to ensure that the track is not easily deformed under high load. The trapezoidal cross-section design enables the side support frame 7 to better resist lateral and longitudinal deformation when subjected to force. The reinforcing ribs 8 are distributed in a triangular shape, which further enhances the structural stability of the main support frame 6 and prevents loosening under high load.

[0027] The limiting component includes a support plate 9, which is fixedly connected to the bottom of the vehicle body 1. A plurality of limiting protrusions 11 are equidistantly arranged on the support plate 9. The support plate 9 is slidably connected to a cover, which can be placed on the outside of the bolt 3 of the auxiliary support mechanism 4. The cover is provided with an elastic member that can be placed between adjacent limiting protrusions 11. Two sliding grooves 10 are provided on the support plate 9, and the two sliding grooves 10 are located on both sides of the limiting protrusion 11.

[0028] The covering part includes a hollow frame 12, one end of which is fixedly connected to two sliding sliders 13. The cross-section of the sliding slider 13 is trapezoidal, and the sliding slider 13 can slide along the inner wall of the slide groove 10. A covering plate 14 is fixedly connected to one side of the hollow frame 12, and the covering plate 14 can fit with the outer wall of the bolt 3 after tightening on the auxiliary support mechanism 4.

[0029] The elastic member includes a positioning rod, which is fixedly connected to the two ends of the inner wall of the hollow frame 12. A limiting ratchet block 16 and two torsion springs 15 are provided on the positioning rod. The two torsion springs 15 are respectively fixedly connected to the side walls of the limiting ratchet block 16 and the side walls of the hollow frame 12. The limiting ratchet block 16 can extend between adjacent limiting protrusions 11. A sliding hole is provided on the limiting ratchet block 16, and the limiting ratchet block 16 is rotatably connected to the positioning rod through the sliding hole.

[0030] When the support frame 12 is in a state of being screwed to the support fixing seat 2 by the bolt 3, the bolts 3 are kept in the same horizontal plane, and the horizontal movement pressure is applied to the hollow frame 12 to make the sliding block 13 of the hollow frame 12 slide on the inner wall of the slide groove 10. During the sliding process, the multiple limiting protrusions 11 will contact and squeeze the limiting ratchet block 16. After being squeezed, the limiting ratchet block 16 will rotate with the positioning rod as the fulcrum, and act on the torsion spring 15 during the rotation process, so that it is squeezed and generates a reaction force. By sliding the hollow frame 12 to the specified position, the covering plate 14 is located on the outside of the bolt 3, and the limiting ratchet block 16 is placed between the two limiting protrusions 11 to achieve the effect of horizontal locking. During the high-strength operation of the auxiliary support mechanism 4 and the support fixing seat 2, the bolt 3 becomes loose, resulting in its axial spiral movement. At this time, the bolt 3 will fit with the covering plate 14, and the axial movement of the bolt 3 is blocked by the covering plate 14, thereby achieving the tightening of the bolt 3 and ensuring the overall stability.
