Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a motor twisting device for an elevator. Background Art

[0002] The motor-driven device of the elevator is one of the key components in the entire elevator system, which is mainly responsible for driving the lifting platform to rise and fall. This device usually consists of three parts: motor, transmission device and driving mechanism. The first is the motor part, which is usually a kind of electric motor that can convert electrical energy into mechanical energy to drive the rotation of the driving mechanism. The choice of motor depends on the weight and load size of the lifting platform, as well as the requirements of the working environment, such as temperature, humidity, etc. The second is the transmission device part, which is responsible for transmitting the power of the motor to the driving mechanism. Common transmission devices include belts, chains, bevel gears, etc., which can be selected according to the specific working environment and conditions.

[0003] Since complex drive methods, such as gear boxes or hydraulic cylinders, increase the cost of using the lift, a motor-driven device and a cable are used to replace the complex structure to reduce costs. The cables on the existing motor-driven device need to be replaced after long-term use, and the complexity of the replacement device may reduce work efficiency. This complexity may come from many aspects, such as unreasonable design of the replacement device, cumbersome operation procedures, and the need for cooperation from multiple people. This situation will increase the time-consuming process of replacing the cable and increase the difficulty of operation, thereby reducing work efficiency. Utility Model Content
