Traction machine

Abstract

The invention discloses a traction machine which comprises a machine body. The machine body comprises a machine base provided with a maintenance face, a motor junction box and a brake assembly. The machine base is provided with a first installation part and a second installation part which are located on the maintenance face. The motor junction box is arranged on the first installation part. The brake assembly comprises a brake arranged on the machine base, and a brake junction box arranged on the second installation part. The brake and the brake junction box are electrically connected. Thus, when a worker stands on a lift car to conduct regular maintenance on the traction machine, the worker can directly face the motor junction box, the brake junction box and other parts needing to be maintained, and therefore convenience and effectiveness of maintenance can be greatly improved, the maintenance difficulty is lowered, the working reliability of the traction machine is improved, meanwhile, a machine body of the traction machine can be lighter and thinner, and the occupied installation space is small.

Description

technical field [0001] The invention relates to the technical field of elevator braking devices, in particular to a traction machine. Background technique [0002] At present, with the rapid development of science and technology and the continuous improvement of people's living standards, machine room-less elevators are developing very fast in China. Due to the advantages of machine room-free elevators, green environmental protection, and energy saving, more and more used in construction. The machine room-less elevator saves the machine room, and arranges the control cabinet, speed limiter, traction machine and other equipment in the original machine room in the hoistway. In some installation spaces where the hoistway is narrow and the height of the top floor is limited, the projection surface of the traction machine should not coincide with the projection surface of the car, so it is necessary to thin the structure and installation of the traction machine. It is the most ...

AI Technical Summary

Problems solved by technology

Since the back of the traction machine is against the wall, both sides are close to the main rail and auxiliary rail, and the height of the top floor is limited, the maintenance space for the traction machine can only be in front of the main machine, and the maintenance personnel perform maintenance on the top of the car Operation

At present, most of the devices and components that require frequent maintenance on most traction machines are usually arranged on the back or side of the machine body. The structure is relatively complicated, and the body size is relatively thick, which makes it difficult for maintenance personnel to perform maintenance and is inconvenient to assemble and disassemble. , the maintenance efficiency and effect are not good, which makes the long-term work of the traction machine a great safety hazard
