Capturing device for broken belt of belt conveyer

Abstract

The invention relates to a capturing device for a broken belt of a belt conveyer. A conveyer belt of the conveyer comprises a loading belt and a return belt. The capturing device comprises a frame, a loading rubber belt capturing mechanism, a return rubber belt capturing mechanism, an upper and lower linkage device and an adjusting unlocking mechanism, wherein the loading rubber belt capturing mechanism comprises an upper turning frame assembly and a lower turning frame assembly which are arranged in the frame, can be turned up and down and are located in a same upright position; the return rubber belt capturing mechanism comprises a return belt turning frame assembly and a cross beam; the return belt turning frame assembly is arranged in the frame, can be turned up and down and is in a same horizontal position of the lower turning frame assembly; the cross beam is located under the return belt turning frame assembly; the upper and lower linkage device is located on one outer side of the frame and comprises an upper linkage mechanism and a lower linkage mechanism; and the adjusting unlocking mechanism is located on the other outer side of the frame in the manner of being symmetrical to the upper and lower linkage device and comprises an upper capturing adjusting mechanism and a lower capturing adjusting mechanism. The capturing device provided by the invention has the advantages of compact structure, big braking force, capability of realizing the capturing linkage of the loading belt and the return belt, few malfunctions and capturing reliability, and is free from damagingthe conveyer belt.

Description

technical field [0001] The invention relates to a belt conveyor broken belt capture device used for emergency braking and broken belt capture when the belt conveyor breaks. Background technique [0002] Today, belt conveyors have become the main conveying equipment for bulk materials and bulk materials, and are widely used in industries such as coal, metallurgy, electric power, chemical industry, ports and building materials. However, once the conveyor belt falls due to a broken belt or a reverse accident caused by the failure of the backstop, the conveyor frame will be destroyed, the equipment will be damaged, and the transportation roadway will be blocked, resulting in long-term production stoppage, major economic losses, and even casualties. [0003] For conveyor belt fracture accidents, the most important protection measure at present is to install a broken belt protection device on the conveyor, also known as a catcher. In recent years, mechanical and hydraulic broken ...

AI Technical Summary

Problems solved by technology

In recent years, mechanical and hydraulic broken belt protection devices or technologies have appeared at home and abroad, but from the perspective of actual use, they are far from meeting the requirements of on-site use. The main shortcomings of these existing protection devices or technologies are as follows:

[0004] 1. The catcher relies on the movement caused by the reverse running caused by the broken belt to trigger the action. However, due to the complexity of the operating environment, the speed of the conveyor belt changes, the local tension disappears, and the drooping displacement increases, which is easy to cause arrest. The malfunction of the device affects the production

[0005] 2. The actuator of the catcher adopts brake block or eccentric wheel mechanism, the braking area is small, the braking force is concentrated, and it is easy to cause the conveyor belt to tear

[0006] 3. There is a lack of necessary considerations in the design of the catcher, which results in a large amount of work and difficulty in the installation, adjustment, and maintenance of the catcher, making it difficult to ensure the good working condition of the catcher and the reliability of the catch action; for example The reset function of the catcher after the broken belt is caught is not considered in the current technology, that is, the unlocking effect; Regulatory problems

[0007] 4. The catcher can only simply capture the carrying belt (upper tape), and there is no linkage mechanism between the carrying belt and the return belt (lower tape), which easily causes secondary damage to the broken belt
