The angle adjustment box 6 is fixedly connected to the bottom end of the cantilever 7 through the double-bolt angle limiting rod 602. A transfer line wheel 603 is movably connected to one side of the upper surface of the angle adjustment box 6. The cantilever 7 includes a large arm 701, and a rotating wheel 702 is fixedly connected to the bottom end of the large arm 701. The rotating wheel 702 is rotatably connected to the inside of the angle adjustment box 6. A plurality of through holes are provided on the outer wall of the rotating wheel 702, and the inside of the through holes is sleeved on the outer wall of the double-bolt angle limiting rod 602. The inside of the large arm 701 is hollow. Limiting through holes 703 are evenly provided on both sides of the upper arm 701, and a limiting pin 704 is sleeved inside the limiting through hole 703.

A rope ring 706 is fixedly connected to the upper surface of the top of the upper arm 701, and a suspension rope 8 is movably connected to the center of the inner wall of the rope ring 706. A small arm 707 is movably connected to the center of the inner side of the upper arm 701. Through holes are evenly provided on both sides of the small arm 707.

[0027] When emergency rescue personnel are setting up and adjusting life-saving equipment in a limited space, they first turn the rotating wheel 702 to a suitable angle, and then insert the double-bolt angle limit rod 602 into the angle limit hole 601, so that the double-bolt angle limit rod 602 is sleeved in the through hole on the outer wall of the rotating wheel 702, thereby fixing the angle of the cantilever 7, and then adjust the distance of the small arm 707 inside the large arm 701. After reaching the appropriate distance, the limit pin 704 is sleeved on the inner wall of the limit through hole 703, and the limit pin 705 is inserted at one end of the limit pin 704. At this time, the suspension rope 8 slides on the inner wall of the transfer wheel 603, the rope ring 706 and the pulley 708.

[0028] like Figure 5-6 As shown, the rope winding wheel 9 is movably connected to the bracket 901 through a bearing, and the bracket 901 is fixedly connected to the side wall of the support platform 5.

[0029] When emergency rescue personnel are performing lifting and hoisting operations for life-saving operations in confined spaces, if it is necessary to quickly lower the lifting rope 8 and the weight of the hoisted object is heavy, they can use tools to tighten the fixing bolts 904, so that gear 1 903 is fixedly connected to the rope reel 9, and then by starting the motor switch 907, under the high-speed rotation of the drive motor 905, the gear 2 906 fixedly connected to its output shaft begins to rotate, and the gear 1 903 meshing with the gear 2 906 rotates accordingly. Since gear transmission has the advantages of stable transmission and large bearing capacity, it can be better applied to life-saving operation environments with large hoisting masses. When hoisting small objects and requiring higher precision in the hoisting height, the workers can loosen the fixing bolts 904 to make the rope reel 9 and the gear 1 903 directly movably connected. At this time, the lifting and lowering of the lifting rope 8 is controlled by manually shaking the handle 902.

[0030] like Figure 1-2 As shown, a reinforcing rib 401 is fixedly connected to the outer wall of the bottom end of the column 4, a plurality of positioning holes 402 are opened at the bottom end of the column 4, a connecting bolt 403 is sleeved at the center of the inner wall of the positioning hole 402, the base 1 is fixedly connected to the bottom end of the column 4 by the connecting bolt 403, and a brake caliper 201 is sleeved on the outer wall of the universal wheel 2.

[0031] When emergency rescue personnel assemble the life-saving hoisting equipment on site, they use the connecting bolts 403 to fix the column 4 to the base 1 through the positioning hole 402, and at the same time, after quickly pushing the hoisting equipment to a suitable position through the universal wheel 2, they press the brake caliper 201 to lock the universal wheel 2 to ensure the overall stability of the equipment.

[0032] Working principle: using the overall structure of the device, when emergency rescue personnel are rescuing people in a limited space, they push the base 1 to a suitable position, lock the universal wheel 2, and then stack the weighted sandbags 3 on the upper surface of the base 1. According to the space conditions at the rescue site, adjust the angle adjustment box 6 to place the cantilever 7 at a suitable angle, and then adjust the length of the cantilever 7 to a suitable position. By retracting the rope 8 through the rope reel 9, the hook 10 can be raised and lowered to the rescue point in the limited space. The hook 10 is connected to the object to be hoisted through the safety buckle 11, and then the rope reel 9 is used to reel in the rope 8 until the hoisting and rescue operation is completed. Emergency rescue personnel When constructing and adjusting the lifesaving equipment in a limited space, first turn the rotating wheel 702 to a suitable angle, then insert the double-bolt angle limiting rod 602 into the angle limiting hole 601, so that the double-bolt angle limiting rod 602 is sleeved in the through hole on the outer wall of the rotating wheel 702, thereby fixing the angle of the cantilever 7, and then adjust the distance of the small arm 707 inside the large arm 701. After reaching a suitable distance, sleeve the limiting pin 704 on the inner wall of the limiting through hole 703, and insert the limiting pin 705 into a section of the limiting pin 704, so as to adjust the length of the small arm 707. At this time, the suspension rope 8 is on the transfer line wheel 60 3. The inner wall of the rope ring 706 and the pulley 708 slide. When emergency rescue personnel are performing lifting and hoisting operations for life-saving operations in limited spaces, when it is necessary to quickly lower the hoisting rope 8 and the weight of the hoisted object is large, the fixing bolt 904 can be tightened by a tool to fix the gear 1 903 and the rope reel 9. Then, by starting the motor switch 907, under the high-speed rotation of the drive motor 905, the gear 2 906 fixedly connected to its output shaft begins to rotate, and the gear 1 903 meshing with the gear 2 906 rotates accordingly. Since the gear transmission has the advantages of stable transmission and large bearing capacity, it can be better It is suitable for life-saving operation environments with large hoisting masses. When hoisting small objects and requiring higher precision in the hoisting height, workers loosen the fixing bolts 904 to make the rope wheel 9 and the gear 903 directly movably connected. At this time, the lifting rope 8 is controlled by manually shaking the handle 902. When emergency rescue personnel assemble the life-saving hoisting equipment on site, they use the connecting bolts 403 to fix the column 4 to the base 1 through the positioning hole 402. At the same time, after quickly pushing the hoisting equipment to a suitable position through the universal wheel 2, they press the brake caliper 201 to lock the universal wheel 2 to ensure the overall stability of the equipment.
