Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the existing master controller has a large volume and takes up a large space, which is not convenient for the installation of a compact console; it does not have its own button, and the action of the controlled part needs to be controlled by the button on the console. Control, inconvenient operation; poor anti-misoperation, easy to cause safety accidents, and the operation process is complicated, and the operator has a large workload

Abstract

The invention provides a master controller. The master controller comprises a holding handle, a rotating mechanism and a universal-joint mechanism connected in sequence, a resetting mechanism and a cam mechanism respectively fitted with the universal-joint mechanism, and circuit boards fitted with the holding handle and the cam mechanism. The master controller, provided by the invention, has the benefits of compact and reasonable structure, accordance with ergonomics requirements, low demand on mounting space, effective prevention from false operations, high operation comfort level and long service life.

Description

technical field [0001] The invention relates to the field of handling machinery, in particular to a master controller for controlling hoisting machinery. Background technique [0002] The master controller (also known as the master switch) is mainly used in the electric transmission device to open and close the contacts in a certain order to achieve the purpose of issuing commands or realizing interlocking and switching of control lines. It is suitable for occasions where the circuit is frequently switched on and off. It is often used with a magnetic starter to implement long-distance control of the starting, braking, speed regulation and reversing of the wound asynchronous motor. It is widely used in the control of various lifting machinery system. [0003] The action of the controlled part in the hoisting machinery is usually realized through the buttons on the console in the control system. This implementation method is inconvenient to operate, poor in preventing misuse,...
