Problems solved by technology

[0003] The operating handles of existing hoisting machinery are usually large in size and occupy a large space, which is not convenient for the installation of compact consoles. The existing operating handles also have the problem that the gear switching is not smooth, and the gear switching signals cannot be accurately transmitted. Timely feedback to the operator, the operation process is complicated, and the operator has a large workload
In addition, the low service life is also a common phenomenon of existing operating handles, and frequent replacement and maintenance work affects the normal work progress

Abstract

The invention discloses an operating handle. The operating handle comprises a driving mechanism (1), a resetting mechanism (2), a transmission mechanism (3), and a contact set (4) successively from inside to outside; the driving mechanism (1) is used for providing driving force through generation of displacement, and sending the driving force to the contact set (4) through the transmission mechanism (3), so that the contact set (4) is used for controlling external equipment operation; the resetting mechanism (2) is arranged around the driving mechanism (1), and realizing resetting of the driving mechanism (1) after displacement generation to an original position. The operating handle is compact in structure, small in occupied area, flexible and convenient in operation, long in service life, and high in versatility.

Description

technical field [0001] The invention relates to the control field of loading and unloading machinery, in particular to an operating handle. Background technique [0002] The control of hoisting machinery often requires the operating handle set in the cab to issue a large number of instructions, including the walking of the crane and the lifting of the hook. [0003] The operating handles of existing hoisting machinery are usually large in size and occupy a large space, which is not convenient for the installation of compact consoles. The existing operating handles also have the problem that the gear switching is not smooth, and the gear switching signals cannot be accurately transmitted. Feedback to the operator in time, the operation process is complicated, and the operator's workload is heavy. In addition, the low service life is also a common phenomenon of existing operating handles, and frequent replacement and maintenance work affects the normal work progress. [0004...
