[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Embodiment 1:

[0030] Reference Figures 1 to 4 As shown, the utility model provides a trackless transport road panel connecting buckle for mining, comprising a pressure plate 1, a plurality of limit parts are fixedly arranged on the top of the pressure plate 1, a pressing part is arranged on the limit part, and a plurality of road panel monomers 8 are connected and fixed on the pressure plate 1 through the limit parts and the pressing parts;

[0031] The limiting part includes a limiting column 2 vertically fixed to the top of the pressure plate 1, and a connecting piece 1 is arranged on the limiting column 2, and the pressing part is fixedly connected to the limiting column 2 through the connecting piece 1.

[0032] The pressure-bearing plate 1 is provided to support a plurality of road panel monomers 8, and the limit portion is provided to limit the jointed plurality of road panel monomers 8. The clamping portion is provided to connect with the limit portion so that the clamping portion acts on the road panel monomer 8, so that the plurality of road panel monomers 8 are connected and fixed to form a whole.

[0033] The utility model is simple and practical, easy and quick to install and disassemble, realizes the firm connection of multiple road panel monomers, effectively avoids the problem of road panel falling off and damage, improves transportation efficiency and safety, and has broad application prospects and promotion value.

[0034] It should be noted that the pressure plate 1 is made of high-strength steel material. The size of the pressure plate 1, the number of limit columns 2 and the distribution of the limit columns 2 on the pressure plate 1 are determined according to the number of road panel units 8 to be spliced. The limit columns 2 are fixedly connected to the pressure plate 1 by welding to improve the connection strength between the limit columns 2 and the pressure plate 1. In order to prevent rust, anti-rust paint is sprayed on the surface of the pressure plate 1 and the limit columns 2.

[0035] Furthermore, the pressing part includes a rod body 4, a pressing piece is fixedly provided on the top end of the rod body 4, a second connecting piece is fixedly provided on the outer wall of the rod body 4, and the second connecting piece is adapted to the first connecting piece.

[0036] Furthermore, the first connecting member is an internal threaded hole 3 provided on the limiting column 2 , and the internal threaded hole 3 and the limiting column 2 are coaxially arranged.

[0037] Furthermore, the second connecting member includes an external thread 5 coaxially arranged on the rod body 4, the external thread 5 is fixedly wound on the outer wall of the rod body 4, the rod body 4 is connected and fixed to the limit column 2 through the external thread 5 and the internal thread hole 3, and an anti-fall rubber layer is coated between the external thread 5 and the internal thread hole 3, thereby further improving the reliability of the connection between the rod body 4 and the limit column 2.

[0038] Furthermore, in order to ensure that the pressing member presses the road slab monomer 8 , the height of the limiting column 2 is equal to the thickness of the road slab monomer 8 .

[0039] Furthermore, the pressing member includes a pressing plate 6 coaxially fixedly sleeved on the rod body 4 , and a rotating fixed block is arranged at the top end of the pressing plate 6 .

[0040] Furthermore, the rotating fixed block is a regular polygonal block 7.

[0041] Furthermore, the number of the limiting parts is not less than two.

[0042] The mining trackless transport road panel connecting buckle provided by the utility model has a working principle as follows: the limiting column 2 is correspondingly inserted into the road panel monomer 8, and the splicing of multiple road panel monomers 8 on the pressure plate 1 is completed, the rod body 4 is pre-tightened on the limiting column 2, and is buckled on the regular polygonal block 7 through the opening of the wrench. When the external thread 5 and the internal thread hole 3 of the rod body 4 are screwed together, the rod body 4 drives the pressure plate 6 to approach the road panel monomer 8 and press the road panel monomer 8 to complete the tightening. In order to improve the reliability of the tightening of the rod body 4 on the limiting column 2, anti-fall glue can be applied on the rod body 4 and the external thread 5.

[0043] Embodiment 2:

[0044] Reference Figures 5 to 8As shown, the difference between this embodiment and the first embodiment lies in that grooves are provided on the opposite side walls of the regular polygonal block 7, a stop block 15 is slidably connected in the groove, one end of a spring 16 is fixedly connected to the inner bottom wall of the groove, and the other end of the spring 16 is fixedly connected to a side of the stop block 15 close to the inner bottom wall of the groove. The stop block 15 is extended out of the groove and pressed against the wrench by the rebound force of the spring 16, which can be used with wrenches of different opening sizes, and is convenient for the wrench to clamp and fix the regular polygonal block 7 and rotate the rod body 4.

[0045] The end of the limiting column 2 close to the pressure plate 1 passes through the pressure plate 1 and is provided with an anti-slip assembly. The junction of the limiting column 2 and the pressure plate 1 is fully welded and fixed by welding. The anti-slip assembly includes a pull rod 11. A horizontal blind hole is provided on the inner wall of the end of the limiting column 2 away from the regular polygonal block 7. A lock tongue 13 is slidably connected in the horizontal blind hole. One end of the pull rod 11 is fixedly connected to the lock tongue 13. The pull rod 11 passes through the horizontal blind hole and extends out of the side wall of the limiting column 2 and is fixedly connected with a handle 12. A spring 14 is sleeved on the pull rod 11. The spring 14 is arranged in the horizontal blind hole. One end of the spring 14 is fixedly connected to the bottom wall of the horizontal blind hole, and the other end of the spring 14 is fixedly connected to the lock tongue 13. The end of the lock tongue 13 away from the spring 14 is an inclined surface; the end of the rod body 4 away from the regular polygonal block 7 is coaxially fixed with a cone 9, and the top side wall of the cone 9 is provided with an annular groove 10, which is matched with the lock tongue 13.

[0046] When in use, the limiting column 2 is correspondingly inserted into the road panel monomer 8, and multiple road panel monomers 8 are spliced ​​on the pressure plate 1, the rod body 4 is pre-tightened on the limiting column 2, and the opening of the wrench is buckled on the regular polygonal block 7, and clamped by the stop block 15. At this time, the wrench is rotated to screw the rod body 4 together with the external thread 5 and the internal threaded hole 3. The inclined surface of the cone 9 pushes the inclined surface of the lock tongue 13 to continue to move downward, and the lock tongue 13 compresses the spring 14 and moves into the horizontal blind hole. When it moves to the annular groove 10, the lock tongue 13 extends into the annular groove 10 under the action of the spring 14 to lock the rod body 4. At this time The pressure plate 6 is just pressed tightly on the road panel monomer 8 to complete the tightening. The lock tongue 13 is firmly extended into the annular groove 10 through the spring 14, so that the lock tongue 13 and the annular groove 10 are limited and cooperated to prevent the rod body 4 from loosening and falling off from the limiting column 2, thereby improving the reliability of the connection and ensuring safety. When it is necessary to disassemble the regular polygonal block 7, pull the handle 12, and the handle 12 drives the lock tongue 13 to overcome the elastic force of the spring 14 and move into the horizontal blind hole, so that the lock tongue 13 falls out of the annular groove 10, and rotate the regular polygonal block 7 in the opposite direction to rotate the rod body 4 out of the limiting column 2, and remove the regular polygonal block 7 from the limiting column 2 to complete the disassembly.
