Electro-hydraulic control clamping loose belt linkage device for maintenance and inspection of inclined belt conveyor

Abstract

An electro-hydraulic control clamping loose belt linkage device for maintenance and inspection of inclined belt conveyors. During the normal operation and maintenance conditions of the belt conveyor, the upper and lower belts are synchronized by designing the upper and lower clamping mechanisms. Clamping; through the design of the lifting cylinders on both sides and the upper and lower sliding beams, the positions of the upper and lower sliding beams are controlled in different working conditions, and the free switching of the device between normal operating conditions and maintenance conditions is realized, which has stronger adaptability and reduces manufacturing costs and Workload; through the design of the drive cylinder to drive the ratchet shell and the toothed sprocket to deflect, the toothed chain can clamp and pull the belt during the working process; through the design of multiple toothed chains to clamp the belt, realize multi-point The pressure distribution of the pressure tape is uniform to avoid the extra directional pressure caused by the deformation and clamping of the tape, which not only increases the service life of the device, but also makes the clamping tape more stable, safe and reliable.

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. Big potential safety hazard. At present, the main entrainment device of the belt conveyor belt is marked with artificial bo...

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 series system of multiple belt conveyors each 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-area adhesive layer peeling off, and exposed steel wire ropes will occur, which will greatly reduce the strength of the belt. Big potential safety hazard. At present, the main entrainment device of the belt conveyor belt is 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

[0003] 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
