Wedge type full-section belt breakage protection device for upward belt conveyor

Abstract

The invention discloses a wedge type full-section belt breakage protection device for an upward belt conveyor, which comprises a frame, an upper redirection roller and a lower redirection roller. A material slide is arranged between the upper redirection roller and the lower redirection roller and above a belt and fixed onto the frame, a wedge is arranged in a slide way which is mounted on a horizontal beam disposed on the frame, and a unidirectional roller is arranged on the lower portion of the wedge. The frame comprises upper crossbeams, upper longitudinal beams, oblique columns, lower crossbeams, lower longitudinal beams, vertical beams, the horizontal beam and column pedestals. The wedge comprises a wedged frame, a rubber block parallel to the belt is embedded to the lateral side of the wedged frame, a gap is reserved between the rubber block and the belt, wing plates are arranged on two sides of the slope of the wedged frame respectively, and a roller support is arranged at the bottom of the wedged frame. The device is high in capture force, so that a complex hydraulic power system is omitted, and cost is reduced. Once the belt is broken, since a capture device is extremely short in route, real-time capture can be realized, brake energy can be reduced, and equipment is protected.

Description

technical field [0001] The invention relates to a broken belt protection device for a belt conveyor, in particular to a wedge-type full-section broken belt protection device for an upward belt conveyor suitable for large-volume coal transportation. Background technique [0002] Currently used upper belt conveyor broken belt protection devices mostly use paired catchers to catch the unloaded side of the belt. Although it has a certain effect, there are problems such as small catch force, easy tearing of the belt, and Disadvantages such as the structure blocking the conveying of materials and the asynchronous action of the catcher. There are also a small number of belt conveyors that adopt the working method of full-section capture: one is to directly press the capture device on the belt covered with bulk materials to achieve capture, and the other is to lift the belt first and extend it. After a while, clip the belt into the catcher to catch it. These two full-section captu...

Problems solved by technology

These two full-section capture methods have the advantages of large capture force and uniform force on the belt section, but they both require high-power hydraulic drive systems, belt speed detection devices and complex control systems, and there are explosion-proof requirements. The problem of high and poor operating economy, and the former also has the defect that the sharp gangue and coal blocks caught between the belt and the catcher damage the belt

In addition, in order to prevent the accumulated materials from colliding with the arresting device, some of the function modules of the arrester must be far away from the belt, so the action stroke of the arrester is longer, which is not conducive to immediate arrest and increases the capture capacity.
