Abstract

The invention relates to an electricity-driven fast cable traction device, belonging to the technical field of carrying equipment. In the traction device, a motor is connected with a power supply through a lead to obtain drive electricity. The motor is directly connected with a reducer to transfer the torque and the rotational speed to a driving friction wheel and control transmission control of the speed and the direction of the motor to the friction wheel through a control button of an operation handle, thereby driving the whole device and the burden to ascend or descend according to a given speed and a given direction. A load is connected with a pull ring of a vertical plate. One end of a cable is fixed, the other end of the cable enters a space between an upper cable inlet block and alower cable inlet block, and a lateral wheel groove of a driven friction wheel extends out of the space between the upper cable inlet block and the lower cable inlet block to become a free end after winding the driving friction wheel and the driven friction wheel. The traction device has the advantages of convenient operation, time saving, simple and compact structure, light weight, capability ofoperation and control by a single hand of an operator, convenient operation and reliable work and can be used for various aloft operations such as firefighting rescue, high-rise cleaning and the like.

Description

technical field [0001] The invention relates to an electric energy-driven fast rope traction device, which belongs to the technical field of carrying equipment. Background technique [0002] According to the visible data analysis of existing climbing devices, existing rope traction devices with similar technical features all have problems such as heavy weight of the device itself, slow climbing speed, complicated loading process, and poor stability. As invented by Lawrence G. Fridman, Esq, Silber & Fridman, US Patent No. 20060017047 is a power-driven climbing mechanism (POWERED ROPE CLIMBING APPARATUS). This patent introduces a rope traction device driven by a motor or other power source, which uses a built-in power source and a friction drive mechanism to realize load transportation. The surface knurled cam mechanism is used as the braking device in the moving mechanism, and a 4-stage planetary gear train is used in the transmission mechanism. The main disadvantage of thi...
