Drum type full-section broken belt protection device

Abstract

The invention discloses a drum type full-section belt breakage protection device, and belongs to the technical field of belt conveyors. The drum type full-section belt breakage protection device comprises a machine frame, an upper fixed friction pair in an arc-shaped structure, an upper movable friction pair in the arc-shaped structure, a lower fixed friction pair in the arc-shaped structure, a lower movable friction pair in the arc-shaped structure, a hydraulic cylinder, a return spring and a pressure sensor, wherein the side surface of the machine frame is longitudinally provided with a sidecarrier roller, and the middle part of the machine frame is provided with a transverse belt carrier roller; and the upper fixed friction pair and the upper movable friction pair are arranged on the upper part of the machine frame to jointly form an upper executing mechanism, the upper movable friction pair can rotate around a rotating shaft to be close to the upper fixed friction pair, the lowerfixed friction pair and the lower movable friction pair are arranged on the lower part of the machine frame to jointly form a lower executing mechanism, and the lower movable friction pair can rotatearound the rotating shaft to be close to the lower fixed friction pair; and the hydraulic cylinder and the return spring are longitudinally fixed on the machine frame. The device has the advantages ofsimple structure, low cost, large catching force, no secondary injury to a conveyer belt and wide application.

Description

technical field [0001] The invention belongs to the technical field of belt conveyors, relates to a conveyor belt protection device, and in particular relates to a drum-type full-section belt-breaking protection device. Background technique [0002] With the development of industry, belt conveyors have been widely used in various fields, but also put forward higher requirements for belt conveyors. In the application of belt conveyors, long-distance, large-capacity, and large-angle conveying methods have become the development direction of belt conveyors in the future, but what follows is that due to long-term high-load operation, the conveyor belt is too tight And the problem of broken belt caused by some uncertain factors. Belt breakage accidents will not only cause huge economic losses, but also cause machine damage and death. [0003] The existing conveyor belt breaking technology protection device has the following shortcomings: 1) the structure is complex, and the ope...

In the application of belt conveyors, long-distance, large-capacity, and large-angle conveying methods have become the development direction of belt conveyors in the future, but what follows is that due to long-term high-load operation, the conveyor belt is too tense And the broken belt problem caused by some uncertain factors

Broken belt accidents will not only cause huge economic losses, but even cause aircraft crashes and fatalities.

[0003] The existing conveyor belt breakage technology protection device has the following disadvantages: 1) The structure is complex, and the operation and maintenance are cumbersome and complicated; 3) The instantaneous friction force is very large, which easily causes secondary damage to the conveyor belt, and the reset of the device is difficult; 3) Expensive, increasing operating costs
