Electric hoist handle

Abstract

The invention discloses an electric hoist handle, which comprises a main shaft. A connecting plate, a display screen box, a connecting ring, a handle and a lifting ring are sequentially arranged on the main shaft from top to bottom; the two ends of the connecting plate are connected with the display screen box through bolts respectively; a locking nut in threaded connection with the top end of themain shaft is in press fit with the upper surface of the connecting plate; a connecting cylinder is installed on the connecting plate through bolts; and a steel wire rope fixing shaft coaxial with the main shaft is in interference fit in the connecting cylinder through a thrust ball bearing. The electric hoist handle makes the handle and the lifting appliance combined into a whole, is compact instructure, and can be suitable for hoisting small-size objects; the steel wire rope fixing shaft can rotate along the main shaft through cooperation of the thrust ball bearing and the steel wire ropefixing shaft, so that winding prevention of a steel wire is achieved; and tension and pressure sensors are arranged in the connecting ring and embedded in the main shaft, and are equipped with sensorbase plates, so that external interference is greatly reduced, and force measurement is more accurate.

Description

technical field [0001] The invention relates to the field of electric hoist, in particular to an electric hoist handle. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places. The control handle and the spreader of the existing electric hoist are separately arranged, and its structure is not compact enough. At the same time, the spreader of the existing electric hoist has defects such as steel wire winding, inaccurate force measurement, and poor bearing of the main shaft. Contents of the invention [0003] Technical issues resolved [0004] Aiming at the deficiencies in the prior art, the present invention provides a handle for an electric hoist, which solves the problem that the control handle and the spre...
