Description
Technical field
The present invention relates to a kind of coal mine machinery, particularly the double-stranded chain mat machine hydraulic pressure in mining limit chain tension adjusting device.
Background technology
At present, use the double-stranded chain mat machine transportation coal in limit and spoil very extensive in the work of China's coal-mine down-hole mining.In using the process of chain mat machine, because requirements of one's work, the chain rupture of chain mat machine or to close the chain operation all very frequent is in chain rupture or close in the process of chain and all must just can carry out under the situation of tight chain.Traditional chain rupture, to close the chain method be on the stuck pressure chain device on the head shell of chain one end, reversing igniting then, holds coupling link with hand and remove or hang up.This method relies on the chain tension state manual task of electrical motor crawl driving torque moment maintenance, if move inaccurate, operation failure in the moment that coupling link is removed or hung up, need operation again, operation process is abnormally dangerous, is easy to occur chain and collapses safety misadventures such as people, the crowded hand of coupling link, electromechanical appliance damage.Through extensively retrieval, do not find comparatively desirable technical scheme as yet.
Summary of the invention
The objective of the invention is in order to solve the double-stranded chain mat machine in present stage limit in chain rupture or to close the shortcoming that has potential safety hazard in the process of chain, and the mining limit double-stranded chain mat machine hydraulic pressure chain tension adjusting device that proposes.
To achieve these goals, the present invention has adopted following technical scheme:
Mining limit double-stranded chain mat machine hydraulic pressure chain tension adjusting device, it is characterized in that: comprise one group of scraper plate, the cross section of scraper plate is the I-shaped structure that has ladder, connects chain at the two ends of scraper plate by coupling link, and each coupling link links together two chains.The front end of described coupling link is the slotted ring that matches with chain, is provided with the connecting panel of symmetry at the opening part of slotted ring, is provided with through hole at connecting panel, is connected on the scraper plate by connecting pin in the through hole.Go up fixture block of clamping respectively on two scraper plates therein, two scraper plates in interval between two fixture blocks.Connect a Hydraulic Pump by connecting pin between two fixture blocks, Hydraulic Pump connects hydraulic check valve by flexible pipe, and hydraulic check valve connects the head and the tail valve by flexible pipe.Utilize the flexible state of head and the tail valve and hydraulic check valve control Hydraulic Pump, thus the work of finishing chain rupture or closing chain.
On the basis of technique scheme, following further technical scheme can be arranged:
The below of described fixture block front end is provided with an opening that matches with scraper plate, leading flank at opening is provided with the boss that matches with the stepped I-shaped structure of scraper flight, above the fixture block front end, be provided with four reinforced ribs, be provided with a Connection Block that is hinged with Hydraulic Pump in the fixture block rear end, Connection Block is a U-shaped bearing.
The invention has the advantages that: this device is by long-range feed flow, utilize Hydraulic Pump stretch finish the chain rupture of chain mat machine or close chain work, its process is succinctly efficient, has greatly improved the safety of work, reduce difficulty and the danger of work, guaranteed worker's job safety.

The specific embodiment
As depicted in figs. 1 and 2, mining limit provided by the invention double-stranded chain mat machine hydraulic pressure chain tension adjusting device, it is characterized in that: comprise one group of scraper plate 2, the cross section of scraper plate 2 is the I-shaped structure that has ladder, two ends at scraper plate 2 connect chain 6 by coupling link 7, and each coupling link 7 links together two chains 6.Go up fixture block 1 of clamping respectively on two scraper plates 2 therein, two scraper plates 2 in interval between two fixture blocks 1.Connect a Hydraulic Pump 3 by connecting pin between the Connection Block 1d of two fixture blocks 1, Hydraulic Pump 3 connects hydraulic check valve 4 by flexible pipe 8, and hydraulic check valve 4 connects head and the tail valve 5 by flexible pipe 8.
In conjunction with shown in Figure 4, the front end of described coupling link 7 is the slotted ring 7a that matches with chain 6, is provided with the connecting panel 7b of symmetry at the opening part of slotted ring 7a, is provided with logical 7c hole at connecting panel 7b, is connected on the scraper plate 2 by connecting pin at logical 7c place.
In conjunction with shown in Figure 3, the below of described fixture block 1 front end is provided with an opening 1a who matches with scraper plate 2, be provided with scraper plate 2 at the leading flank of opening 1a and have the boss 1b that the I-shaped structure of ladder matches, above fixture block 1 front end, be provided with four reinforced rib 1c, be provided with Connection Block 1d in fixture block 1 rear end, Connection Block 1d is a U-shaped bearing.
Principle of work
Head and the tail valve 5 be four position three-way valve groups, head and the tail valve 5 under the out-of-run state of zero-bit, the direct oil sump tank of feed liquor.
When head and the tail valve 5 left side, feed liquor enters hydraulic check valve 4 and for the feed liquor cylinder body toward Hydraulic Pump 3, Hydraulic Pump 3 shrinks under the effect of feed liquor power, blocks scraper plate 2 move toward one another and begins tight chain work thereby drive anchor clamps fixture block 1.Chain 6 begins to relax during tight chain, when slackness reaches can set out coupling link 7 time, stops the feed liquor feed flow, and this moment, feed liquor power is closed, pinned to the nonreturn valve core of hydraulic check valve 4 inside, and the slackness of chain 6 is maintained, and coupling link 7 begins to set out.
When head and the tail valve 5 right positions, feed liquor enters hydraulic check valve 4 and supplies the liquid cylinder that returns of past Hydraulic Pump 3, Hydraulic Pump 3 stretches out under the effect of feed liquor power, thereby drive fixture block 1 and block scraper plate 2 relative motions, progressively tensioning of chain 6, this moment, fixture block 1 broke away from scraper plate 2, at this moment stop the feed liquor feed flow, feed liquor power is closed, pinned to the nonreturn valve core of hydraulic check valve 4 inside, takes anchor clamps fixture block 1 and Hydraulic Pump 3 away, and chain mat machine is far controlled the tight chain operation of hydraulic pressure and finished.
