High-strength belt breakage protection device

Abstract

The invention discloses a high-strength belt breakage protection device. The high-strength belt breakage protection device comprises two electromagnetic adsorption head supports located above a high-strength belt, a plurality of internally-attached steel wires are embedded in the high-strength belt, the electromagnetic adsorption head supports are n-shaped supports, electromagnetic adsorption heads are hoisted on the inner sides of the electromagnetic adsorption head supports, and a protective hammer support is arranged between the two electromagnetic adsorption head supports and is an n-shaped support. The device is simple and reliable in structure, the running state of the high-strength belt can be rapidly fed back and output to the electromagnetic adsorption heads in time, once a signalis abnormal, the adsorption states of the electromagnetic adsorption heads and protective hammers are disengaged, it is ensured that the protective hammers fall down in time, a protective foundationframe can be clamped in a matched mode when the protective hammers fall down, and the effect of preventing the belt from freely running is achieved; and the electromagnetic adsorption head supports and the protective hammer support are both designed in a closed mode and can prevent the broken belt from moving out of a belt frame.

Description

technical field [0001] The invention relates to mining machinery, in particular to a high-strength belt break protection device. Background technique [0002] When the mine high-strength belt is in operation, due to mechanical reasons or belt quality and other reasons, the belt may break, causing safety accidents to mechanical equipment and personnel, and affecting the normal production of the mine. [0003] Although there are also some devices that provide certain protection after the belt breaks, the problems of these devices include: complex structure, easy dust collection, insensitive action, and easy failure. Contents of the invention [0004] The object of the present invention is to provide a high-strength belt breakage protection device to solve the problems raised in the above-mentioned background technology. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] A high-strength belt breakage protection d...
