Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] Example 1
[0025] Regarding the problem 1 mentioned above: When the electric hoist of the existing lifting equipment moves to the end of the slide rail, it is easy to impact the sliding end, which will damage the slide rail and the electric hoist.
[0026] The solution is as follows: A safety protection device for lifting machinery includes a device body 1. The device body 1 includes a support column 2, a sliding rail 3, an electric hoist 4, a reinforcing frame 5, an anti-collision stabilizing device 6, and an adsorption device 7. The sliding rail 3 is installed on the top left side of the support column 2. The electric hoist 4 is installed on the sliding rail 3. The reinforcing frame 5 is installed at the connection between the top of the sliding rail 3 and the support column 2. The anti-collision stabilizing device 6 is installed at the bottom left end of the sliding rail 3. The adsorption device 7 is installed at the left end of the electric hoist 4. The anti-collision stabilizing device 6 includes a mounting block 8 and an anti-collision device 9. The mounting block 8 is L-shaped. The structure includes a shock absorber 9 mounted on the right end of the mounting block 8. The shock absorber 9 comprises a shock absorber cylinder 10, a shock absorber spring 11, and an inlet head 12. The shock absorber spring 11 is installed inside the shock absorber cylinder 10. The inlet head 12 is installed on the right end of the shock absorber cylinder 10, with its left end located inside the shock absorber cylinder 10. A pressure plate 13 is provided on the left end of the inlet head 12; the pressure plate 13 has a circular shape. A positive magnetic block 14 is provided on the right end of the inlet head 12; the positive magnetic block 14 has a cylindrical shape. An embedding groove 15 is formed on the right end of the positive magnetic block 14; the embedding groove 15 has a cylindrical shape. The adsorption device 7 includes a fixing block 17 and a negative magnetic... Block 18, the negative magnetic block 18 is installed at the left end of the fixed block 17. The left end of the negative magnetic block 18 is provided with an embedded post 19, which is cylindrical in shape. When the electric hoist 4 moves to the end of the sliding track 3, the adsorption device 7 at the left end of the electric hoist 4 can impact the guide head 12 in the anti-collision device 6. Then, the pressure plate 13 at the rear end of the guide head 12 can press the shock-absorbing spring 11 in the shock-absorbing cylinder 10. During the pressing process, the shock-absorbing spring 13 can consume the impact force. Finally, the spring 13 rebounds, thereby protecting the sliding track 3 and the electric hoist 4. To prevent damage from collision, during the collision, the negative magnetic block 18 in the adsorption device 7 can adhere to the positive magnetic block 14 on the anti-collision stabilizing device 6, and then the embedded post 19 of the negative magnetic block 18 can be inserted into the embedded groove 15 of the positive magnetic block 14. Since both the negative magnetic block 18 and the positive magnetic block 14 are made of magnets, the embedded post 19 can be attracted into the embedded groove 15. In this way, the stability of the electric hoist 4 during hoisting can be guaranteed and displacement can be prevented. If it needs to be pulled out, simply drive the electric hoist 4, and the electric hoist 4 can pull the adsorption device 7 out of the anti-collision stabilizing device 6.
[0027] Both the right side of the positive magnetic block 14 and the left end of the negative magnetic block 18 are provided with buffer washers 16. The buffer washers 16 are in the shape of a ring and are made of rubber. The buffer washers 16 are for the purpose of buffering during impact and preventing damage from the impact between the negative magnetic block 18 and the positive magnetic block 14.
[0028] The reinforcing frame 5 includes a reinforcing arm 20, a first welding block 21, and a second welding block 22. The reinforcing arm 20 has an L-shaped structure. The first welding block 21 is installed at the right end of the reinforcing arm 20, and the second welding block 22 is installed at the bottom of the reinforcing arm 20. The reinforcing arm 20 is provided with reinforcing ribs 23. The reinforcing frame 5 is used to fix and reinforce the support column 2 and the sliding rail 3, thereby improving the supporting force of the sliding rail 3, preventing the sliding rail 3 from bending or falling off, greatly improving the structural firmness and stability, and also improving safety.
[0029] The bottom of the support column 2 is trapezoidal and the top is rectangular, forming a Y-shaped structure, which effectively improves the stability of the bottom of the support column 2.
[0030] Regarding the second problem to be solved above: During hoisting, the electric hoist of the existing lifting equipment may shift, which will affect the stability of the hoisting.
[0031] The solution is as follows: During the impact, the negative magnetic block 18 in the adsorption device 7 can adhere to the positive magnetic block 14 on the anti-collision stabilizing device 6, and then the embedded post 19 of the negative magnetic block 18 can be inserted into the embedded groove 15 of the positive magnetic block 14. Since both the negative magnetic block 18 and the positive magnetic block 14 are made of magnets, the embedded post 19 can be adsorbed into the embedded groove 15. In this way, the stability of the electric hoist 4 during hoisting can be guaranteed and displacement can be prevented. If it needs to be pulled out, simply drive the electric hoist 4, and the electric hoist 4 can pull the adsorption device 7 out of the anti-collision stabilizing device 6.
[0032] Working principle: During operation, when the electric hoist 4 moves to the end of the sliding track 3, the suction device 7 at the left end of the electric hoist 4 impacts the guide head 12 inside the anti-collision device 6. Then, the pressure plate 13 at the rear end of the guide head 12 presses down on the shock-absorbing spring 11 inside the shock-absorbing cylinder 10. During the pressing process, the shock-absorbing spring 13 dissipates the impact force. Finally, the spring 13 rebounds, thus protecting the sliding track 3 and the electric hoist 4 from collision damage. During the impact, the suction device 7... The negative magnetic block 18 can be attached to the positive magnetic block 14 on the anti-collision stabilizing device 6, and then the embedding post 19 of the negative magnetic block 18 can be inserted into the embedding groove 15 of the positive magnetic block 14. Since both the negative magnetic block 18 and the positive magnetic block 14 are made of magnets, the embedding post 19 can be attracted into the embedding groove 15. In this way, the stability of the electric hoist 4 during hoisting can be guaranteed and displacement can be prevented. If it needs to be pulled out, simply drive the electric hoist 4, and the electric hoist 4 can pull the adsorption device 7 out of the anti-collision stabilizing device 6.

By combining the above-mentioned components, this utility model can effectively prevent the electric hoist from impacting the end of the slide rail, thereby protecting the slide rail and the electric hoist and improving the safety of the lifting equipment during use.
