Electrohydraulic control clamping and belt loosening linkage device for maintenance of inclined belt conveyor

Abstract

The invention provides an electrohydraulic control clamping and belt loosening linkage device for maintenance of an inclined belt conveyor. According to the device, in the normal operation and maintenance working condition process of the belt conveyor, an upper clamping body mechanism and a lower clamping body mechanism are designed, so that synchronous clamping of an upper rubber belt and a lowerrubber belt is achieved; lifting cylinders on the two sides, an upper sliding beam and a lower sliding beam are designed, and the different working condition positions of the upper sliding beam and the lower sliding beam are controlled, so that free switching of the device between the normal operation working condition and the maintenance working condition is achieved, the adaptability is higher,and the manufacturing cost and the workload are reduced; a driving oil cylinder is designed to drive a ratchet wheel housing and a tooth-shaped chain wheel to deflect, so that the clamping and belt pulling functions of tooth-shaped chains on the upper rubber belt in the working process are achieved; and the multiple tooth-shaped chains are designed to clamp the rubber belts, so that the pressuredistribution of the multi-point pressurized rubber belts is uniform, the extra direction pressure generated by deformation and clamping of the rubber belts is avoided, the service life of the device is prolonged, and the rubber belts can be clamped more stably, safely and reliably.

Description

technical field [0001] The invention relates to a clamping tape device for maintenance and repair of a belt conveyor, in particular to an electro-hydraulic control clamping and loosening belt linkage device used in the process of maintenance and repair of a belt conveyor. Background technique [0002] In industries such as coal and non-coal mines, about 30 billion tons of loose materials (coal, iron and non-ferrous metal ores, etc.) are transported through a multi-belt conveyor series system every year, and many cases are long-distance , high-speed, heavy-load inclined transportation; due to the year-round operation of the belt conveyor, after the belt has been used for a certain period of time, the phenomenon of belt aging, large-scale rubber layer peeling off, and exposed steel wire ropes will occur, which will greatly reduce the strength of the belt. a major security risk, [0003] At present, the main entrainment device of the conveyor belt of the belt conveyor is to be...

Problems solved by technology

[0002] In industries such as coal and non-coal mines, about 30 billion tons of loose materials (coal, iron and non-ferrous metal ores, etc.) are transported through a multi-belt conveyor series system every year, and many cases are long-distance , high-speed, heavy-load inclined transportation; due to the year-round operation of the belt conveyor, after the belt has been used for a certain period of time, the phenomenon of belt aging, large-scale rubber layer peeling off, and exposed steel wire ropes will occur, which will greatly reduce the strength of the belt. a major security risk,

[0003] At present, the main entrainment device of the conveyor belt of the belt conveyor is to be marked with artificial boards, and the entrainment method is discontinuous

It is mainly to pull the tape out from the wellhead for a certain distance by winch or manually, and then use manual tools to place artificial boards near the wellhead. For the main inclined shaft conveyor belt with long distance, large slope and large transport volume, Generally, multiple winches are used for belting. Generally, it takes 4-5 hours to pull out the tape and put on the artificial board. The process of pulling the tape is discontinuous and takes too long

[0004] Publication No. CN203092108U is a utility model patent for "a tape clamping device for easy connection and fixing". Complicated, heavy workload, time-consuming and labor-intensive; there is also a utility model patent for "entrainment device for belt conveyor" with publication number CN202670586U. This patent mechanism is composed of multiple rollers, including many auxiliary components, and has a complex structure. Larger volume, higher requirements for operation, higher application cost
