Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A single-track lifting beam for a coal mine single-track hoisting locomotive, including a lifting beam frame 1, a cargo rack 3, a hanging ring 10, and a universal wheel 15. A cargo rack 3 is provided on the lower side of the lifting beam frame 1, and a support plate 4 is fixedly connected to the upper side inside the cargo rack 3. A hanging ring 10 is provided at the upper end of the support plate 4. Clamping grooves 11 are opened at the four corners of the lower side inside the cargo rack 3. A buffer assembly is provided in the middle of the inner wall of the clamping groove 11, and the buffer assembly is used to reduce the impact loss caused when the cargo rack 3 is placed and used;

[0022] Furthermore, a suspension hook 2 is connected to the lower end of the outer wall of the lifting beam frame 1 through a hanger, and the outer wall surface of the suspension hook 2 is adapted to the middle of the inner wall of the hanging ring 10. When in use, the suspension hook 2 can pass through the middle of the inside of the hanging ring 10 to drive the cargo rack 3 to be suspended.

[0023] Furthermore, a sleeve 5 is fixedly connected to the upper end of the outer wall of the support plate 4, a chute 6 is opened in the middle of the inside of the sleeve 5, a screw rod 7 is inserted through the middle of the inside of the chute 6 through a bearing, a rotary handle 8 is fixedly connected to the lower end of the outer wall of the screw rod 7, a screw sleeve 9 is threadedly connected to the outer wall surface of the screw rod 7, and a hanging ring 10 is provided at the upper end of the outer wall of the screw sleeve 9. When in use, by rotating the rotary handle 8, the screw rod 7 is driven to rotate, and the thread on the outer wall of the screw rod 7 enables it to perform a threaded movement, driving the hanging ring 10 at the upper end of the screw sleeve 9 to a vertical position, so that the cargo rack 3 can be used at an appropriate height position.

[0024] Furthermore, the outer wall surface of the screw sleeve 9 is adapted to the inner wall surface of the sliding groove 6, and the screw sleeve 9 only moves vertically within the inner wall of the sliding groove 6. This structure can ensure that when the hanging ring 10 is suspended or held by hand and the screw rod 7 rotates, the screw sleeve 9 will not rotate simultaneously. When the screw sleeve 9 moves through the rotation of the screw rod 7, it will perform a threaded movement, thereby driving the hanging ring 10 to move vertically along the outer wall surface of the screw rod 7.

[0025] Furthermore, the buffer assembly includes a spring 12. The spring 12 is arranged in the middle of the inner wall of the card slot 11. The lower end of the outer wall of the spring 12 abuts against a damping block 13. The outer wall surface of the damping block 13 is provided with bumps. The lower end of the outer wall of the damping block 13 is fixedly connected to a telescopic rod 14, and the lower end of the outer wall of the telescopic rod 14 is connected to a universal wheel 15. This structure can, through the compression and rebound effect of the spring 12, ensure that the goods rack 3 remains in contact with the ground during placement or use, and reduce the shaking frequency to avoid partial damage to the use of the hanging beam rack 1.

[0026] Furthermore, the outer wall surface of the damping block 13 is adapted to the inner wall surface of the card slot 11. The outer wall surface of the telescopic rod 14 is provided with a folding tube 16. This structure can prevent the universal wheel 15 from causing partial damage to the lower edge of the outer wall of the goods rack 3 due to excessive impact force during use.

[0027] Working principle: During use, the goods rack 3 can be suspended. By rotating the knob 8 at the lower end of the support plate 4, it rotates and drives the screw rod 7 in the sleeve 5 to rotate. When the screw rod 7 rotates, it will perform a threaded movement on the screw sleeve 9 through the outer wall surface, so that the screw sleeve 9 can move vertically within the sliding groove 6. Then, the screw sleeve 9 drives the hanging ring 10 to move vertically. After that, the hanging ring 10 can be adapted to the hanging hook 2, thereby suspending the goods rack 3 for use, and making the universal wheel 15 contact the ground. Then, it will drive the telescopic rod 14 and the damping block 13 to squeeze the spring 12 in the card slot 11, causing the spring 12 to generate partial resilience after being squeezed, so that the universal wheel 15 is always in contact with the ground. When the hanging beam rack 1 starts, it will drive the goods rack 3 to move. During the movement, the shaking impact that the goods rack 3 may cause can be reduced to avoid damage. The above is the entire working principle of this utility model.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claimed rights involved.
