Problems solved by technology

[0003] There are one or more of the following disadvantages in the catcher scheme, mainly as follows: first, the catcher and the conveyor share a frame, and its strength is low, and the frame may be deformed during the catch; second, the catch At the same time, only the edge parts on both sides of the conveyor belt are caught, and the contact area between the catch block and the conveyor belt is small, which will cause great damage to the conveyor belt; third, there are many transmission parts, and dust and materials can easily block the movement of the moving parts, reducing the catch. The reliability; fourth, because they use the conveyor belt to run in reverse to generate the catcher action, so when the conveyor belt is parked and the conveyor belt is reversed for a short distance, it is easy to cause misoperation

Abstract

The invention discloses a broken-belt catching device comprehensive performance safety test system with a buffer device. The broken-belt catching device comprehensive performance safety test system comprises a machine tail frame, a hydraulic pushing oil cylinder, a tail portion roller, a transition roller set, a conveying belt, the buffer device, a movable type broken-belt catching device, a fixed type broken-belt catching device, a machine head frame, a hydraulic automatic tensioning device, a head portion roller, a tensioning wheel, a steel wire rope, a supporting frame and a weight box. The broken-belt catching device comprehensive performance safety test system with the buffer device is reasonable and compact in structure, safe and reliable, catching performance of the broken-belt catching devices can be effectively tested, the reliable basis is provided for further application of the broken-belt catching devices, the safety running coefficient of a belt conveyor can be effectively increased, and the accident that people are hurt by the broken belt of the belt conveyor is effectively avoided.

Description

technical field [0001] The invention relates to a comprehensive performance safety test system of a broken belt capture device with a buffer device. Background technique [0002] At present, there are many technical schemes for the catcher used for belt conveyor protection, but a considerable part of them adopts the principle of swing block type. The wedge-shaped block in these catchers is fixed on the upper part or outside of the frame. When a broken belt occurs, the block is driven to swing by some kind of power drive device, reducing the gap between the block and the driving wheel, and grasping the belt. catch. If divided according to different power sources, it can be divided into two types: friction drive type and electro-hydraulic type; the former drive roller is located under the conveyor belt, which is eccentric or ratchet backstop type, and the drive wheel rotates normally when the conveyor belt is running normally. . When the belt is broken, the friction generat...
