Description
Technical field
The present invention relates to a kind of coal mine machinery, particularly mining limit double-strand chain mat machine chain hydraulic chain tightener.
Background technology
At present, limit double-strand chain mat machine transport coal and spoil is used in the work of China's coal-mine down-hole mining widely.In the process of usage chain trigger, due to requirements of one's work, the chain rupture of chain mat machine or to close chain operation all very frequent, chain rupture or close chain process in all just can must carry out under the situation of tight chain.Traditional chain rupture, to close chain method be on stuck for the chain one end pressure chain device on head shell, igniting of then moveing backward, removes with hand-held coupling link or hang up.The chain tension state manual task that this method relies on electrical motor crawl driving torque to keep instantaneously, if, operation failure inaccurate in the moment action that coupling link is removed or hung up, need operation again, operation process is abnormally dangerous, is easy to occur the safety misadventures such as chain collapses people, coupling link squeezes hand, electromechanical appliance damage.Through extensively retrieval, not yet find ideal technical scheme.
Summary of the invention
The object of the invention is in order to solve present stage limit double-strand chain mat machine chain rupture or close chain process in there is the shortcoming of potential safety hazard, and the mining limit double-strand chain mat machine chain hydraulic chain tightener proposed.
To achieve these goals, present invention employs following technical scheme:
Mining limit double-strand chain mat machine chain hydraulic chain tightener, is characterized in that: comprise one group of scraper plate, and the cross section of scraper plate is the stepped I-shaped structure of band, and connect chain at the two ends of scraper plate by coupling link, two chains link together by each coupling link.The front end of described coupling link is the slotted ring matched with chain, is provided with symmetrical connecting panel, connecting panel is provided with through hole, is connected on scraper plate in through hole by connecting pin at the opening part of slotted ring.Two scraper plates are gone up respectively clamping fixture block wherein, two, interval scraper plate between two fixture blocks.Between two fixture blocks, connect a Hydraulic Pump by connecting pin, Hydraulic Pump connects hydraulic check valve by flexible pipe, and hydraulic check valve connects head and the tail valve by flexible pipe.Utilize the retracted position of head and the tail valve and hydraulic check valve hydraulic control pump, thus carry out the work of chain rupture or conjunction chain.
On the basis of technique scheme, following further technical scheme can be had:
The below of described fixture block front end is provided with an opening matched with scraper plate, the leading flank of opening is provided with the boss that I-shaped structure stepped with scraper flight matches, four reinforced ribs are provided with above fixture block front end, be provided with a Connection Block be hinged with Hydraulic Pump in 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 flexible come chain mat machine chain rupture or close chain work, its process is succinctly efficient, drastically increases the safety of work, reduce difficulty and the danger of work, ensure that the job safety of worker.

Detailed description of the invention
As depicted in figs. 1 and 2, mining limit provided by the invention double-strand chain mat machine chain hydraulic chain tightener, it is characterized in that: comprise one group of scraper plate 2, the cross section of scraper plate 2 is the stepped I-shaped structure of band, connect chain 6 at the two ends of scraper plate 2 by coupling link 7, two chains 6 link together by each coupling link 7.Two scraper plates 2 are gone up respectively clamping fixture block 1 wherein, two, interval scraper plate 2 between two fixture blocks 1.Between the Connection Block 1d of two fixture blocks 1, connect a Hydraulic Pump 3 by connecting pin, 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.
Shown in composition graphs 4, the front end of described coupling link 7 is the slotted ring 7a matched with chain 6, is provided with symmetrical connecting panel 7b, connecting panel 7b is provided with logical 7c hole, is connected on scraper plate 2 at logical 7c place by connecting pin at the opening part of slotted ring 7a.
Shown in composition graphs 3, the below of described fixture block 1 front end is provided with an opening 1a matched with scraper plate 2, the leading flank of opening 1a is provided with the boss 1b matched with stepped I-shaped structure with scraper plate 2, four reinforced rib 1c are provided with above fixture block 1 front end, 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 is four position three-way valve groups, and valve 5 is under the out-of-run state of zero-bit from beginning to end, the direct oil sump tank of feed liquor.
When 5 left, head and the tail valve, feed liquor enters hydraulic check valve 4 and is supplied to the feed liquor cylinder body of Hydraulic Pump 3, and Hydraulic Pump 3 shrinks under the effect of feed liquor power, thus drives fixture fixture block 1 to block scraper plate 2 move toward one another to start tight chain work.During tight chain, chain 6 starts to relax, when slackness reach can set out coupling link 7 time, stop feed liquor feed flow, now the nonreturn valve core of hydraulic check valve 4 inside is closed, is pinned feed liquor power, the slackness of chain 6 is maintained, starts coupling link 7 of seting out.
When the right position of head and the tail valve 5, feed liquor enters hydraulic check valve 4 and is supplied to time liquid cylinder of Hydraulic Pump 3, Hydraulic Pump 3 stretches out under the effect of feed liquor power, thus drive fixture block 1 to block scraper plate 2 relative motion, chain 6 progressively tensioning, now fixture block 1 and scraper plate 2 depart from, at this moment feed liquor feed flow is stopped, the nonreturn valve core of hydraulic check valve 4 inside is closed, is pinned feed liquor power, and take fixture fixture block 1 and Hydraulic Pump 3 away, chain mat machine is far controlled the tight chain operation of hydraulic pressure and terminated.
