Abstract
The invention discloses a safe and high-efficiency chain-tensioning device of a scraper conveyor, which comprises a manual hydraulic jack, a steel wire rope and a connector, wherein a middle section of the steel wire rope is fixed at the head part of the hydraulic jack; two ends of the steel wire rope are sleeved on connecting pins of the connector which has a U-shaped structure; and the connecting pin is inserted into two side plates of the connector and is movably matched with the connector. The chain-tensioning device comprises the manual hydraulic jack, the steel wire rope and the connector; the middle section of the steel wire rope is fixed at the head part of the hydraulic jack; and two ends of the steel wire rope are sleeved on the connecting pin of the connector. Therefore, when the chain is required to be tensioned, a chain of the conveyor is tensioned by controlling the stroke of an oil cylinder of the hydraulic jack, thereby unhurriedly carrying out the chain-tensioning operation, not only greatly improving the safety performance, but also doubly improving the working efficiency.
Description
Technical field
The present invention relates to a kind of when being used for slat conveyer increase and decrease intermediate channel, the isolated plant of tension chain.
Background technology
Each laneway opening under the coal mine, repair canopy and driving face all will use slat conveyer.In laneway opening opening driving process, The middle pan of scraper conveyor need add or reduce with the driving progress at any time, and each operation teams and groups all will add or reduce the work of intermediate channel during driving.And add or when reducing intermediate channel; All need to draw conveyor chain in i.e. tension earlier; Making the conveyor chain that needs interpolation intermediate channel place be in relaxed state just can operate; Owing to there is not special chain tension adjusting device, adopt the action button of artificial crawl slat conveyer for a long time always, other two people stand in the headstock side and carry out tight chain or carry out tight chain operation with chain sling.When the action button of artificial crawl slat conveyer is carried out tight chain; Be loose operation of moment that conveyor chain occurs when utilizing the crawl operation; Grasp bad or slat conveyer switch when problem is arranged when some dynamic frequency, cause easily and hinder finger, turn over head, turn over tail, burn motor, chain rupture, draw bad chain stopper, draw the generation of accidents such as bad little and cover plate.During with the tight chain of chain sling, speed is slow, and labor strength is big, and safety factor is low.Therefore, the slat conveyer operation of adding and reduce intermediate channel is continually being perplexed always and is being kept the safety in production.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned prior art exists, a kind of chain tension adjusting device safely and efficiently is provided.
The technical scheme that the present invention adopted is: comprise hand-hydraulic jack, steel rope and adaptor union; The steel rope stage casing is fixed on the hydraulic jack head; Steel rope two is enclosed within on the connecting pin on the adaptor union; Adaptor union is " U " type structure, and connecting pin is through on the biside plate of adaptor union and with adaptor union is movable and cooperates.
The present invention includes hand-hydraulic jack, steel rope and adaptor union, the steel rope stage casing is fixed on the hydraulic jack head, and steel rope two is enclosed within on the connecting pin on the adaptor union; Therefore, when needing tight chain, through the very heavy oil cylinder stroke of modulated pressure; Make the conveyor chain tension of slat conveyer; Thereby can carry out tight chain operation at leisure, not only safety performance improves greatly, and work efficiency also is multiplied.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is that A among Fig. 1 is to view;
Fig. 3 is the scheme drawing of steel rope in the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain, but do not constitute any restriction of the present invention.Illustrated in figures 1 and 2; The present invention includes hand-hydraulic jack (1), steel rope (3) and adaptor union (5); Steel rope (3) stage casing is fixed on hydraulic jack (1) head; Two of steel rope (3) is enclosed within on the connecting pin (4) on the adaptor union (5), and adaptor union (5) is " U " type structure, and connecting pin (4) is through on the biside plate of adaptor union (5) and with adaptor union (5) is movable and cooperates.Shown in Figure 2; During use; Scraper plate (6) is penetrated in the adaptor union (5), adaptor union (5) is put at two of steel rope (3), connecting pin (4) penetrates from the side plate of adaptor union (5); Simultaneously connecting pin (4) is also pierced at two of steel rope (3), connecting pin (4) passes from another side plate of adaptor union (5) then.Shown in Figure 1, the stage casing of steel rope (3) is fixed on the head of hydraulic jack (1), promptly on the piston head of oil cylinder; The base of hydraulic jack (1) withstands scraper plate (6), shakes the handle (2) of hydraulic jack (1), and piston stretches out; Thereby piston drives steel rope (3), steel rope (3) drives connecting pin (4), connecting pin (4) drive adaptor union (5); Final adaptor union (5) drives scraper plate (6) motion, makes the conveyor chain tension on scraper plate (6) conveyer, till the tearing that the chain place is loose open and get off of conveyor chain; Carry out associative operation then, to accomplish the work of adding or reducing intermediate channel.After adding or reduce the work completion of intermediate channel, oppositely shake the handle (2) of hydraulic jack (1), until resetting.
Claims (1)
1. chain-tensioning device of scraper conveyor; It is characterized in that: comprise hand-hydraulic jack (1), steel rope (3) and adaptor union (5); Steel rope (3) stage casing is fixed on hydraulic jack (1) head; Steel rope (3) two is enclosed within on the connecting pin (4) on the adaptor union (5), and adaptor union (5) is " U " type structure, and connecting pin (4) is through on the biside plate of adaptor union (5) and with adaptor union (5) is movable and cooperates.
