Cart running mechanism for bridge cranes

Abstract

The invention discloses a cart running mechanism for bridge cranes, relating to a cart running mechanism for bridge cranes. The cart running mechanism for bridge cranes is composed of a motor, a brake, a speed reducer, a braking wheel coupling and a wheel set. The running mechanism is characterized in that the motor and the brake are fixed on a shell of the speed reducer through a connecting frame, the brake is arranged in the connecting frame, the motor is connected with a high-speed shaft of the speed reducer through the braking wheel coupling, and the coaxiality of the motor and the high-speed shaft of the speed reducer is ensured; a low-speed output shaft of the speed reducer is sleeved on a shaft of the wheel set; and one end of a moment arm is arranged on the shell of the speed reducer, and the other end of the moment arm is arranged on a set frame end beam of the wheel set so as to achieve a fixing effect. The running mechanism disclosed by the invention has the characteristics of novel structure, simple structure, small volume, light weight, low cost, high efficiency, safety, reliability, convenience for maintenance and the like, therefore, the running mechanism disclosed by the invention is an economy and practicability integrated novel cart running mechanism for bridge cranes.

Description

technical field [0001] The cart running mechanism of the bridge crane according to the present invention relates to a cart running mechanism of the bridge crane. Background technique [0002] At present, the operating mechanisms of bridge cranes are mostly arranged horizontally. The motor drives the reducer through the brake wheel coupling, transmission shaft, and half-tooth coupling. The output shaft of the reducer drives the wheel group through the full-tooth coupling to realize the crane translational movement. The motor, reducer and brake are fixed on the walking platform through the base. The main problems with this form of operating mechanism are: [0003] 1. This kind of operating mechanism takes up a lot of space, and all transmission parts are installed on the walking platform of the crane in a plane arrangement; [0004] 2. This kind of operating mechanism has a long transmission chain, many links, and low efficiency. If one link fails, the entire mechanism will...

AI Technical Summary

Problems solved by technology

It is used to solve the existing problems in the prior art: 1. The existing structure has a large volume and a large space in use; 2. The transmission chain of the operating mechanism is long, has many links, low efficiency, and is prone to failure; 3. There are many accessories, resulting in the weight of the whole machine Large; 4. The transmission of the mechanism has high requirements on the rigidity of the walking platform.
