However, this broken belt protection device still has some disadvantages: 1. Although the swing position of the upper brake block is restricted, its swing still has an impact load, which poses a safety hazard; The process of steel plate detachment has certain uncertainty, low sensitivity, and requires frequent maintenance; 3. The friction between the conveyor belt and the lower wedge will reduce the service life of the conveyor belt

Abstract
The invention discloses a conveyor belt breakage prevention device of a belt conveyor. The conveyor belt breakage prevention device is mainly composed of a carrier roller supporting system, a capturing system, a belt breakage detection system and a control system. The conveyor belt breakage prevention device of the belt conveyor is characterized in that the capturing system is mainly composed of a center carrier roller mechanism, an upper brake block mechanism, a lower brake block, a motor driving system and a supporting mechanism. The supporting mechanism is composed of a base, a center carrier roller support, a support, a guiding supporting frame and an upper supporting frame. The upper brake block mechanism is mainly composed of an electromagnet, a round guide rail, an upper brake block, an upper brake block sleeve and a guiding sleeve. The motor driving system is mainly composed of a motor, a coupler and a bidirectional threaded screw rod. The belt breakage detection system is mainly composed of an adjusting bolt, a detection device supporting block, a strong spring, a rear sliding block, a front sliding block, a bearing support, a roller shaft, a bearing and a trapezoid guide rail. The control system comprises a PLC, a belt breakage signal detection proximity switch, an upper brake block proximity switch, a lower brake block proximity switch, an upper brake block stroke switch, an upper brake block sleeve stroke switch, a motor driver and an electromagnet driver.
Description
technical field [0001] The invention relates to mining machinery equipment technology, in particular to a broken belt protection device for a belt conveyor. The broken belt protection device is driven by a motor, and the designed upper and lower brake blocks can simultaneously press the conveyor belt to provide broken belt protection. Background technique [0002] Belt conveyor is a very common continuous transportation equipment in production, and it is widely used in coal, metallurgy, building materials and other departments. It has the advantages of strong transportation capacity, small working resistance, low power consumption, long transportation distance and long service life. [0003] The existing broken belt protection device of the belt conveyor has a blocking effect on the transportation of coal and other ores due to the protruding part of the upper brake block, and may even cause danger. For this reason, someone has studied a "wedge type belt conveyor broken bel...
