Large arm angle indicating device for hoisting equipment

Abstract

The invention discloses an large arm angle indicating device for hoisting equipment. According to the main points of the technical scheme, the large arm angle indicating device comprises a mounting plate, a mounting shell is fixedly connected to the top of the mounting plate, and an angle indicating dial and an intelligent angle gauge are fixedly mounted in an inner cavity of the mounting shell; the angle indicating dial comprises a dial and an angle pointer which are fixedly connected in the inner cavity of the mounting shell, a lighting assembly used for improving the lighting effect is arranged in the inner cavity of the mounting shell, and a transparent observation cover is fixedly connected to an end opening of the mounting shell; a sliding assembly is arranged at the top of the mounting plate, and a cleaning assembly used for cleaning the transparent observation cover is arranged at the top of the sliding assembly; and the problem that in the prior art, an angle indicating device cannot automatically clean a transparent observation cover, dust and other impurities are prone to being attached, and consequently the angle value cannot be clearly observed is effectively solved.

Description

technical field [0001] The invention belongs to the field of hoisting equipment, and in particular relates to a boom angle indicating device for hoisting equipment. Background technique [0002] Most lifting equipment starts a vertical or vertical and horizontal working stroke after retrieving the material. After reaching the destination, it is unloaded, and then travels empty to the reclaiming location to complete a working cycle, and then carry out the second lifting or handling. Generally speaking, when the lifting equipment is working, retrieving, moving and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent. The hoisting equipment is mainly used to carry pieces of goods. It can carry bulk materials such as coal, ore and grain after being equipped with a grab bucket, and liquid materials such as molten steel can be lifted after being equipped with a bucket; the boom angle indicating device is installed It is a device fixe...
