Abstract
The utility model discloses a connecting device of hydraulic jack and liquid accuse valve, its characterized in that, hydraulic jack's cavity of resorption is connected to the liquid accuse valve seat board of installing on the cylinder through leading to liquid union coupling, is equipped with a hole and epicoele intercommunication on the liquid accuse valve seat board, and liquid accuse valve seat board is equipped with two holes as the interface of being connected with the liquid accuse valve. The utility model has the advantages that: the base plate is adopted to connect the hydraulic control valve and the jack, so that the whole mechanism for connecting the jack and the hydraulic control valve is more compact, can bear higher pressure, and is convenient to connect and detach.
Description
Technical field
The utility model relates to employed equipment in a kind of coal mining, the connecting device of a kind of specifically coal mine fully-mechanized mining support apparatus hydraulic jack and pilot operated valve device.
Background technology
Jack is the important stressed member of hydraulic support, and it also bears the transverse force of vertical and level except bearing axial force, and the stressing conditions very severe is very easily damaged.The jack of hydraulic support all is to have hydraulic control one-way valve (lock) to be used usually, it connects pattern is that tubular type connects, the epicoele that is jack is connected with hydraulic control one-way valve (lock) by two high-pressure rubber pipes respectively with cavity of resorption, its shortcoming is that the volume that takes up room is big, the easy explosion of high-pressure rubber pipe, cause the hydraulic support performance failure, can not work.
Summary of the invention
The purpose of this utility model is: provide a kind of volume that takes up room less, guarantee the jack of the partially stabilized normal operation of jack hydraulic control.
The technical solution of the utility model is:
The connecting device of a kind of hydraulic jack and pilot operated valve device, it is characterized in that, the cavity of resorption of hydraulic jack is connected to the pilot operated valve device seat board that is installed on the cylinder barrel by fluid-through tube, and the pilot operated valve device seat board is provided with a hole and is communicated with epicoele, and the pilot operated valve device seat board is provided with two holes conducts and pilot operated valve device bonded assembly interface.
The beneficial effects of the utility model are: adopt bed plate to connect pilot operated valve device and jack, make whole jack and pilot operated valve device bonded assembly mechanism more compact, can bear higher pressure, make things convenient for and connect between the two and dismounting, it has improved the reliability of hydraulic support complete machine work widely simultaneously, has reduced manufacturing cost.
Description of drawings
Fig. 1 is a scheme drawing of the present utility model.
Wherein, Reference numeral: 1 is cylinder barrel, and 2 is epicoele, and 3 is fluid-through tube, and 4 is the pilot operated valve device seat board, and 5 is cavity of resorption.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 1, be welded with a pilot operated valve device seat board 4 on the cylinder barrel 1 of hydraulic jack, pilot operated valve device seat board 4 is communicated with the cavity of resorption 5 of jack by fluid-through tube 3, hole by its bottom is communicated with jack epicoele 2, realizes the conveying of highly pressurised liquid.On its panel, leave the pilot operated valve device mounting hole.
Present embodiment in the course of the work, pressure fluid directly enters hydraulic valve seat board 4 by the intercommunicating pore of fluid-through tube 3 and hydraulic valve seat board 4 bottoms, and then be communicated with hydraulic valve mounted thereto, saved high-pressure rubber pipe, simplify the structure of cylinder barrel 1 periphery, and avoided the problem of the easy explosion of high-pressure rubber pipe.
