Broken strap seizing device for belt

Abstract

The invention relates to a broken strap seizing device for a belt. One side of a belt conveying rolling barrel frame is fixedly provided with a speed measuring sensor used for measuring the change of the transmission speed of the belt, while the other end of the belt conveying rolling barrel frame is fixedly provided with a belt seizing device; the belt seizing device consists of a lower clamping plate, an upper clamping plate, a bracket and an oil cylinder; the bracket is fixedly arranged on the belt conveying rolling barrel frame; the lower clamping plate is fixedly arranged at the upper end of the bracket; the upper clamping plate is rotatably fixedly arranged, relative to the lower clamping plate, on the bracket through a rotating shaft; the upper clamping plate is pushed to rotate by the oil cylinder; two sides of the belt conveying rolling barrel frame are provided with a framework-shaped supporting frame; a transmission shaft is transversely erected on the framework-shaped supporting frame; the middle part of the transmission shaft is fixedly provided with a back stopper; two ends, which are located on the back stopper, of the transmission shaft are provided with a telescopic cylinder respectively; telescopic ends of the telescopic cylinders are fixed with a coal shoveling plate; and the transmission shaft is driven by a variable-frequency motor fixedly arranged on one side of the framework-shaped supporting frame. The quick and reliable seizing is utilized for the broken strap seizing device for the belt; a seizing shoe is reasonably designed; and the seizing damage cannot be generated to a transporting strap.

Description

technical field [0001] The invention belongs to the field of mine conveying equipment, and in particular relates to a broken belt arresting device. Background technique [0002] As the main conveying equipment for bulk and bulk materials, belt conveyors have been widely used in industries such as coal, cement, electric power, chemical industry, ports and building materials. However, for a belt conveyor with a large inclination angle, once a broken belt accident occurs, the conveyor frame will be destroyed, the auxiliary equipment will be damaged, and the transportation roadway will be blocked, resulting in long-term production stoppage and major economic losses, and even casualties, which are extremely destructive. serious. There are many relevant casualty data reports in this area both at home and abroad. At present, the most important protection measure for conveyor belt fracture accidents is to install a broken belt protection device on the conveyor, also known as a cat...

AI Technical Summary

Problems solved by technology

In recent years, mechanical, hydraulic and other broken belt protection devices have appeared at home and abroad, but from the actual use situation, they are far from meeting the requirements of on-site use. The main shortcomings are as follows: relying on the reverse movement generated by the broken belt to trigger the catcher action, due to the complexity of the operating environment

[0003] Sexuality leads to malfunction and affects production

The actuator of the catcher adopts a brake block or an eccentric wheel mechanism, the braking area is small, the braking force is concentrated, and it is easy to cause the tape to tear
