Abstract
The invention discloses a thrust mechanism and a hydraulic bracket comprising the thrust mechanism. The disclosed thrust mechanism is applied to the hydraulic bracket, and comprises a thrust jack, thrust rods, a guide body and a slide block, wherein the front end of the thrust jack is in hinged connection with the thrust rod; the guide body can be fixed on a base, and a slipway which extends in a vertical direction is formed; the slide block is in sliding fit with the slipway; and the back end of the thrust jack is in hinged connection with the slide block. According to the thrust mechanism, the thrust mechanism can move relative to the base in the vertical direction along with the slide block by thrusting the back end of the jack; furthermore, the slide block can be positioned at a predetermined position close to the lower end of the slipway, so that an angle between the thrust rod and the thrust jack is kept in an appropriate range; and moreover, the thickness of the base can be reduced, so that the heights of a walking channel, a ventilation section and a passing machine are increased.
Description
Technical field
The passing technology that the present invention relates to mine, particularly a kind of thrust gear for hydraulic support also relates to a kind of hydraulic support that comprises this thrust gear.
Background technology
Hydraulic support is the support apparatus of fully-mechanized mining working, generally comprises base, back timber and thrust gear.Thrust gear generally comprises pusher rod and advancing jack; Rear end and the base of advancing jack are hinged and connected, being hinged and connected of front end and pusher rod; Pusher rod can protrude upward in front and back under the advancing jack effect, to realize passing function.The structure of pusher rod is different and different according to actual conditions; A kind of front-end and back-end of pusher rod can link to each other with drag conveyor respectively, so that corresponding drag conveyor is passed forward or backward.
In the coal mining process, along with base fluctuates, pusher rod can swing with respect to advancing jack, and then the angle between pusher rod and the advancing jack can produce respective change.In order to adapt to the variation of the angle between pusher rod and the advancing jack, prevent that the bottom surface of advancing jack and pusher rod from bumping against, base often needs corresponding thickness, thinks that the angle between pusher rod and the advancing jack changes headspace.In the situation that the working face of coal seam height is constant, base thickness is larger, just needs to reduce the height of walking passage, ventilation section and the machine of mistake.
When thin seam working surface, because the working face of coal seam height is lower, so that walking passage, ventilation section and excessively all corresponding reductions of machine height, this also can affect the safety of exploitation work not only bad for the carrying out of exploitation work and the raising of operating efficiency.
Therefore, when carrying out coal mining activity, especially when girdle is carried out coal mining activity, how in the variation that adapts to the angle between pusher rod and the advancing jack, the thickness that reduces base is the technical barrier that current those skilled in the art need to solve.
Summary of the invention
In view of this, the invention provides a kind of thrust gear for hydraulic support, utilize this thrust gear, can in the variation that adapts to the angle between pusher rod and the advancing jack, reduce the thickness of base.
In addition, the present invention also provides a kind of hydraulic support that comprises this thrust gear.
The thrust gear that provides is used for hydraulic support, comprise advancing jack and pusher rod, front end and the pusher rod of described advancing jack are hinged and connected, and also comprise guide way and slide block, described guide way can be fixed on the base, and forms the slideway that an in the vertical direction extends; Described slide block and described slideway are slidingly matched; The rear end of described advancing jack and described slide block are hinged and connected.
