[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] Please refer to Figures 1-5 , a forklift mast installation structure shown in the figure, including a front frame 1 of the vehicle body. A clamping assembly 2 is provided on the front frame 1 of the vehicle body. The clamping assembly 2 includes a moving plate 21. One end of the moving plate 21 is connected to a clamping plate 27. A limit rod 28 is installed on the clamping plate 27. A bracket 3 is installed on the front frame 1 of the vehicle body. A connecting frame 32 is provided on one side of the bracket 3. Connecting holes 33 are opened at both ends of the connecting frame 32. The limit rod 28 is adapted to the connecting holes 33;

[0023] A slideway 11 is provided on the front frame 1 of the vehicle body. The moving plate 21 is slidably arranged on the slideway 11. A moving groove 23 is opened inside the moving plate 21;

[0024] The clamping assembly 2 includes a motor 29. The output end of the motor 29 is connected to a worm 25. The worm 25 meshes with a worm gear 26. The worm gear 26 is fixed in the middle of a bidirectional threaded rod 24. The bidirectional threaded rod 24 is rotatably connected to the front frame 1 of the vehicle body;

[0025] Both ends of the bidirectional threaded rod 24 are respectively slidably arranged in the moving grooves 23 inside the two moving plates 21. The bidirectional threaded rod 24 is helically connected to the moving plate 21;

[0026] Both upper and lower sides of the bidirectional threaded rod 24 are provided with slide bars 22 in parallel. The slide bars 22 are fixed on the front frame 1 of the vehicle body. Both ends of the slide bars 22 are slidably arranged in another moving groove 23 inside the two moving plates 21;

[0027] The bottom of the bracket 3 is installed on the front frame 1 of the vehicle body through a connecting bolt 31. A lifting assembly 4 is provided in the bracket 3.

[0028] In this solution, when installing the device structure, the staff installs the bracket 3 on the front frame 1 of the vehicle body, aligns the mounting holes at the bottom of the bracket 3 with the mounting holes on the front frame 1 of the vehicle body, and uses the connecting bolts 31 to install the bracket 3 on the front frame 1 of the vehicle body. The lifting component 4 inside the bracket 3 can be lifted to facilitate the fork-lifting of goods at different heights.

[0029] After fixing the bracket 3 with the connecting bolts 31, the clamping component 2 is used to further fix the bracket 3. The motor 29 in the clamping component 2 drives the worm 25 to rotate. By the meshing of the worm 25 and the worm gear 26, the worm gear 26 rotates under the rotation of the worm 25, thereby controlling the rotation of the bidirectional threaded rod 24. When the bidirectional threaded rod 24 rotates, the moving plate 21 screwed to the bidirectional threaded rod 24 moves along the slide rod 22 fixed on the front frame 1 of the vehicle body. Thus, the clamping plate 27 on the moving plate 21 drives the limiting rod 28 into the connection hole 33 on the connecting frame 32, and further realizes the clamping of the bracket 3 to achieve further fixation.

[0030] During the movement of the moving plate 21, the slideway 11 on the front frame 1 of the vehicle body can guide the movement of the moving plate 21. Through the arrangement of the slideway 11 and the slide rod 22, the movement of the moving plate 21 is made more stable. By driving the worm gear 26 to rotate through the worm 25, the self-locking function can be realized. During long-term use, when the connecting bolts 31 become loose and the staff fails to notice in time, the clamping component 2 can ensure the fixation of the bracket 3. The self-locking function of the worm 25 and the worm gear 26 in the clamping component 2 can always keep clamping the connecting frame 32 on the bracket 3, thereby ensuring the stability of the bracket 3. The internal structure of the clamping component 2 is simple, and it can realize the rapid installation of the bracket 3. When the structure needs to be inspected and repaired, its simple structure can reduce the inspection difficulty and at the same time reduce the maintenance cost.
