A multifunctional safety lifter

Abstract

The invention belongs to the technical field of lifters, in particular to a multifunctional safe lifter. The multifunctional safe lifter comprises a lifter body, wherein the lifter body is fixedly provided with a motor and a battery pack for driving the motor to operate; the lifter body is further provided with a winding device; the winding device comprises a winding wheel set and a wire jamming device; the winding wheel set comprises a winding wheel disk; the winding wheel disk is connected with a motor shaft of the motor; a winding accessory wheel set is arranged above the winding wheel disk; and the wire jamming device is arranged by the side of the winding wheel disk. According to the multifunctional safe lifter, the winding accessory wheel set is additionally arranged to change a transverse winding direction to a vertical winding direction, jamming of the lifter and a rope is avoided; a winding wheel is designed as the wheel disk with a larger diameter, so that the contact area of the rope is increased; pulling ropes with different toughness can be matched; friction with the pulling rope is increased via a winding mode of the wheel disk and the winding accessory wheel set; and the structure is simple and practical.

Description

technical field [0001] The invention belongs to the technical field of lifters, in particular to a multifunctional safety lifter. Background technique [0002] In the fields of tourism, sports, fire fighting, anti-terrorism, etc., it is often used to require people to climb up or down along a rope, so as to make people or objects rise to a high place or fall to a low place. In the traumatic method, people often directly contact the rope with their hands, and use the friction between the hands and the rope to achieve the purpose of climbing. This not only limits the climbing height, but also wastes a lot of manpower and material resources. [0003] In the traditional lifter, the winding direction of the pull rope is horizontal, and the diameter of the steering wheel is relatively small. This structure has the following defects: 1. Due to the horizontal winding structure of the lifter, the lifter is used for high-altitude operations. In the process, there will be a tilting si...

Problems solved by technology

In the traumatic method, people often directly touch the rope with their hands, and use the friction between the hands and the rope to achieve the purpose of climbing. This not only limits the climbing height, but also wastes a lot of manpower and material resources.

[0003] In the traditional lifter, the winding direction of the pull rope is horizontal, and the diameter of the steering wheel is relatively small. This structure has the following defects: 1. Due to the horizontal winding structure of the lifter, the lifter is used for high-altitude operations. In the process, there will be a tilting situation, which will cause the elevator and the rope to be stuck, so there is a potential safety hazard; 2. Due to the relatively small diameter of the steering wheel, the contact area between the rope and the steering wheel is not enough, and the steering wheel Insufficient rope tension; 3. In order to solve the problem of insufficient contact area with the steering wheel, the traditional elevator will be equipped with multiple steering wheels, and the contact area will be increased by winding the rope multiple times, but this design requires a high degree of toughness. High special rope; 4. The structure of the winding device is complicated; 5. The friction between the steering wheel and the rope is small, and it is easy to slip
