[0034] Example 2:

[0035] Based on Example 1, as shown in the appendix Figure 4 To be continued Figure 7 As shown:

[0036] This utility model provides a fall-prevention telescopic hoisting auxiliary device for installing electromechanical equipment in coal mines. It also includes a hoisting buckle mechanism, of which four sets are respectively located at the four corners inside the hoisting body 1 and the telescopic body 2. Each hoisting buckle mechanism includes a starting slider 9 and a starting spring 901.

The starting spring 901 is fixedly connected inside the hoisting body 1 and the telescopic body 2, with its upper side fixedly connected to the starting slider 9. During use, when the hoisting body 1 and the telescopic body 2 are placed on the ground, the starting slider 9 slides into the hoisting body 1 and the telescopic body 2. The sliding of the starting slider 9 causes the starting spring 901 to extend and retract, and the elastic force of the starting spring 901 causes the starting slider 9 to slide back to its original position.

[0037] The hoisting buckle mechanism also includes a starting rack 902 and a starting gear 10. The starting rack 902 is fixedly connected to the inner end face of the starting slider 9 and slides inside the hoisting body 1 and the telescopic body 2. The starting gear 10 is rotatably connected to the lower side inside the hoisting body 1 and the telescopic body 2. The starting rack 902 and the starting gear 10 mesh together to form a gear and rack transmission mechanism. During use, the starting slider 9 slides, causing the starting rack 902 to slide, and the starting rack 902 slides, causing the meshing starting gear 10 to rotate.

[0038] The hoisting buckle mechanism also includes: a starting pulley 1001, a starting transmission belt 11, and a blocking pulley 1201; the starting pulley 1001 is coaxially fixedly connected to the outside of the starting gear 10; the blocking pulley 1201 is rotatably connected to the upper inside of the hoisting body 1 and the telescopic body 2, and the lower rotating shaft of the blocking pulley 1201 and the blocking rotating block 12 are coaxially fixedly connected; the starting transmission belt 11 is driven to the outer end faces of the starting pulley 1001 and the blocking pulley 1201. During use, the rotation of the starting gear 10 drives the starting pulley 1001 to rotate, the rotation of the starting pulley 1001 drives the starting transmission belt 11 to rotate, the rotation of the starting transmission belt 11 drives the blocking pulley 1201 to rotate, and the rotation of the blocking pulley 1201 drives the blocking rotating block 12 to rotate.

[0039] The hoisting ring mechanism also includes: a hanging ring protrusion 401 and a blocking protrusion 1202; the hanging ring protrusion 401 is fixedly connected to the lower side of the inner end face of the hoisting ring 4; the blocking protrusion 1202 is fixedly connected to the upper end face of the blocking rotating block 12. The hanging ring protrusion 401 and the blocking protrusion 1202 are magnetically connected. During use, the blocking rotating block 12 rotates, causing the blocking protrusion 1202 to rotate. When the blocking protrusion 1202 rotates to the position of the hanging ring protrusion 401, the hanging ring protrusion 401 and the blocking protrusion 1202 are magnetically attached together, so that the hoisting rope is stably installed inside the hoisting ring 4.

[0040] The specific usage and function of this second embodiment are as follows:

[0041] During use, when the hoisting body 1 and the telescopic body 2 are placed on the ground, the starting slider 9 slides inward into the hoisting body 1 and the telescopic body 2. The sliding of the starting slider 9 causes the starting spring 901 to extend and retract. The elastic force of the starting spring 901 causes the starting slider 9 to slide back to its original position. The sliding of the starting slider 9 causes the starting rack 902 to slide. The sliding of the starting rack 902 causes the meshing starting gear 10 to rotate. The rotation of the starting gear 10 causes the starting pulley 1001 to rotate. The rotation of the starting pulley 1001 causes the starting transmission belt 11 to drive. The starting transmission belt 11 drives the blocking pulley 1201 to rotate. The rotation of 201 causes the blocking block 12 to rotate, which in turn causes the blocking protrusion 1202 to rotate. When the blocking protrusion 1202 rotates to the position of the hanging ring protrusion 401, the hanging ring protrusion 401 and the blocking protrusion 1202 magnetically attach together, so that the lifting rope is stably installed inside the lifting hanging ring 4. When the lifting body 1 and the telescopic body 2 are lifted, the blocking block 12 blocks the lifting hanging ring 4, ensuring the stability of the lifting rope inside the lifting hanging ring 4. When the lifting body 1 and the telescopic body 2 are placed on the ground, the blocking block 12 rotates and opens, making it convenient for workers to remove the lifting rope from inside the lifting hanging ring 4.
