Overhead lifting device

Abstract

The invention discloses an overhead lifting device. The overhead lifting device comprises a support plate, two gears, two rope binding wheels, a steel wire rope and a hollow rod. The two gears are meshed with each other and can be fixed to the support plate in a rotatable mode. The two rope binding wheels are coaxial with the two gears respectively and are fixed to the corresponding gears respectively. The steel wire rope is wound between the two rope binding wheels. The hollow rod is fixed to the upper end of the support plate. The steel wire rope penetrates through the hollow rod. The overhead lifting device further comprises a motor drive system. The motor drive system comprises a motor, a motor gear, a power source and a control switch. The motor is connected with the power source through a power line. Connection between the power line and the power source is controlled by switching on of the control switch. The motor gear is arranged on the motor. The motor gear is connected with the gears in a transmission mode through a first planetary gear. The overhead lifting device further comprises a hand brake device. The hand brake device is used for conducting manual brake of downward gliding. The overhead lifting device has the advantages of being safe, reliable, low in cost, convenient to carry, high in storey height applicability and the like.

Description

technical field [0001] The invention relates to an escape device, in particular to a high-altitude lifting device. Background technique [0002] With the development of my country's social economy, people's material life has improved, and there are more and more high-frequency fire accidents. Solving the fire prevention of current high-rise buildings has been put on the agenda, and the emergency escape and safe evacuation of high-rise personnel are urgent. [0003] At present, the speed of the slow-descent device commonly used in high buildings is uncontrollable, and the friction of the steel wire rope is insufficient, and it is easy to slip, and it is prone to problems such as falling during the descent; in addition, the traditional escape device generally uses a winding wheel to wind the wire rope together. , then the whole device after winding is bulky, heavy, and not easy to carry; there are also problems such as complicated operation, such as the traditional slow-down ...

Problems solved by technology

[0003] At present, the speed of the slow-descent device commonly used in high-rise buildings is uncontrollable, and the friction of the steel wire rope is insufficient, and it is easy to slip, and it is prone to problems such as falling during the descent; in addition, traditional escape devices generally use winding wheels to wind the wire rope together. , then the whole device after winding is bulky, heavy, and not easy to carry; there are also problems such as complicated operation, such as the traditional slow-down device needs to be manually braked before use, and the user is prone to make mistakes when using it at a critical moment, resulting in life. Dangerous; or users are timid and dare not try, etc., they must be used after special training, and it is difficult to carry out popular promotion;
