Abstract
The invention discloses a bottom chain connecting method and a bottom chain connecting device for a scraper conveyer, which relate to a scraper conveyer and are used for solving the problems of complex programs, high labor intensity and unsafe operation environment existing in the conventional chain connecting technology. The method comprises the following steps of: when a bottom chain is broken on a middle part, pulling one end of the broken chain close to a drawer under the condition of leaving a margin; opening a drawer plate; leading another tip ring to an observing hole in a bottom groove nearby; dragging a band chain tool to the observing hole through a drawer port by using a leading rope; connecting a steel wire rope to the back end of the band chain tool; placing the tip ring into the band chain tool for connecting through the observing hole by using a chain clamping tool; applying external force to the steel wire rope after these procedures are completed; releasing an upper chain of a sliding chute timely; dragging the tip ring to the drawer port for connecting; and closing the drawer plate, and connecting the upper chain. The method disclosed by the invention has the advantages of easiness, high practicability, high safety coefficient, reduction in procedure loops and low labor intensity.
Description
Technical field
The present invention relates to scratch board conveyor, be specifically related to chain method of attachment and device at the bottom of scratch board conveyor.
Background technology
In use, chain rupture accident occurs scratch board conveyor often, and particularly, after end chain chain rupture, chain link operation is extremely cumbersome.When chain link, need to remove raw coal near the machine of chain rupture drawer mouth road, find near connecting ring and untie transporter cochain, ensure that can not there be cochain both sides, drawer mouth top, from chain at the bottom of the extraction of drawer mouth, end chain is connected to band chain instrument, put back to again in chute back cover plate, two drawers etc. are at least opened in middle part chain rupture, and this chain link method drawback is near opening drawer mouth, to separate cochain, need repeatedly draw and move cochain and end chain, operating personnel is time length, the operation of multiple spot face in transporter machine road, and labour intensity is large, and operating environment is dangerous.
In order to alleviate operating personnel's labour intensity, improve the safety coefficient of workman operation, reduce the time of shutting down handling failure, be necessary that butt chain process innovates.
Summary of the invention
The present invention is loaded down with trivial details in order to solve the program that existing chain link technology exists, and labour intensity is large, the unsafe problem of operating environment, and chain method of attachment and device at the bottom of a kind of scratch board conveyor are provided.
The present invention is achieved by the following technical solutions:
Chain method of attachment at the bottom of scratch board conveyor, step is:
In the time that end chain breaks at middle part, one end of chain rupture is pulled near drawer place and leaves surplus, open this drawer plate, near kerve peep hole place other end headring causes, band chain instrument is dragged to peep hole place by drawer mouth with messenger, band chain instrument rear end connecting steel wire ropes, by peep hole, termination ring being put into band chain instrument with clip chain instrument again connects, after completing these operations, use by External Force Acting in steel wire rope, untie chute upper chain in good time, termination ring is drawn to drawer mouth and connected, after the drawer plate that closes, connect upper chain;
When end chain breaks when near transporter head or tail, the termination of chain rupture is caused to place peep hole, one end of band chain instrument causes broken end place peep hole after being connected with large chain, utilize clip chain instrument that termination ring is connected to band chain instrument, other end chain link packs drive into, utilize transporter band-type brake to add switching point and touch principle, chain rupture part is caused to head or tail top row chain link again.
Further, in the time pulling band chain instrument, encounter special circumstances to peep hole place walking and make manpower not when stretchy band chain instrument, use tensioning tool to pull band chain instrument.
The device that has been used for chain method of attachment at the bottom of above-mentioned scratch board conveyor, comprises band chain instrument, clip chain instrument, tensioning tool;
Described band chain instrument is by a closed vesica piscis, and is fixed on two semi-closed vesica piscises compositions at closed vesica piscis two ends;
Described clip chain instrument comprises jig arm, and one end of jig arm is oval clamp;
Described tensioning tool comprises pull bar, band tooth roller, drag hook, and pull bar is fixed on band tooth roller,
Drag hook is fixed on band tooth roller by steel wire rope.
The inventive method is applicable to the scratch board conveyor that kerve peep hole is greater than 30 × 40mm bore, the inventive method is combined to Bian tri-teams at malanite tries out, at south 7 10705 working face Bian, with after this chain link new method, operation is simple, and operating personnel's activity duration in transporter road is short, cleaning raw coal scope is little, every subjob only needs 5-6 people, and the chain link time only needs 2-3 hour, saves 50% labour, save activity duration 2-4 hour, improved greatly labor productivity.
According to chain accident statistics at the bottom of malanite scratch board conveyor, full ore deposit reaches 20 every year, by each average calculating in 3 hours of saving, accumulate Bian coal team group and open 60 hours time on opportunity, create production raw coal value and reach millions of units, in addition the saving of safety factor and human resources, economic benefit is very considerable, has very big application and popularization value.
Compared with prior art, the present invention has the following advantages:
(1) chain link method is simple, practical, after chain link principle and operation that operating personnel only need understand, all can carry out chain link operation;
(2) this chain link method is untied cochain, any place, selectively operating face chute top, in personnel's machine road the activity duration short, place is few, safety coefficient is high, process links reduce, labour intensity is low.
