Column.
Background technique
Currently, hydraulic support column used in coal mining is fabricated by alloy materials such as iron, steel, due to coal mine
Subsurface environment is more severe, and work surface humidity is big, and a large amount of corrosive substances, underground equipment are also easy to produce in conjunction with downhole corrosion gas
It works in moist, perishable environment for a long time.If the movement of column is infrequently or even long-time attonity simultaneously, column
Interior liquid medium will be chronically at closed state and cannot flow update, cause liquid medium microbial growth, rotten, acceleration
To corrosion of metal, the service life of hydraulic support column has been seriously affected, while having been brought greatly to downhole safety production
Security risk.
Summary of the invention
It is an object of that present invention to provide a kind of hydraulic support columns for having interior circulatory mediator displacement.
To achieve the above object, the present invention takes following technical proposals:
The hydraulic support column of the present invention for having interior circulatory mediator displacement, including level-one cylinder body, by being arranged described one
The first guide sleeve sealing sliding sleeve at grade cylinder body cylinder mouth is loaded on the intracorporal second level cylinder body of first-stage cylinder, and the second level cylinder body is by setting
The second guide sleeve sealing sliding sleeve at its cylinder mouth is set equipped with portable pillar；Level-one outer wall of cylinder block is equipped with valve seat and valve seat, institute
The valve port for stating valve seat is connected to level-one cylinder body cavity of resorption, and the valve port of the valve seat is connected to the epicoele of level-one cylinder body；Second level cylinder body bottom
Wall is equipped with the hydraulic control valve of connection second level cylinder body cavity of resorption and level-one cylinder body cavity of resorption；The bottom of the portable pillar is provided with hydraulic control
Valve processed offers the hydraulic control runner of circulatory mediator runner and the hydraulic control valve in portable pillar；The circulatory mediator runner
Inlet is connected to the liquid outlet of hydraulic control valve, and the hydraulic control mouth of hydraulic control valve is connected to the liquid outlet of the hydraulic control runner,
The inlet of hydraulic control valve is connected to second level cylinder body cavity of resorption.
The inlet of the liquid outlet of the circulatory mediator runner and the hydraulic control runner is separately positioned on the top of portable pillar.
The invention has the advantages that realizing that hydraulic support column automatic replacing liquid is worked normally without influencing hydraulic support.Greatly
The mobility for increasing column internal hydraulic pressure medium greatly reduces medium and goes bad, realizes the theory of " Running water never becomes putrid ", reduce
The generation of corrosion improves the service life of hydraulic support.Meanwhile column of the invention is without increasing external auxiliary mechanism.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, the hydraulic support column of the present invention for having interior circulatory mediator displacement, including level-one cylinder body 1, lead to
The the first guide sleeve 2 sealing sliding sleeve being arranged at 1 cylinder mouth of level-one cylinder body is crossed loaded on the second level cylinder body 3 in level-one cylinder body 1, second level
Cylinder body 3 passes through the second guide sleeve 4 being arranged at its cylinder mouth and seals sliding sleeve equipped with portable pillar 5；1 outer wall of level-one cylinder body is equipped with
The valve port of first valve seat 12 and the second valve seat 13, the first valve seat 12 is connected to level-one cylinder body cavity of resorption 10, the valve port of the second valve seat 13
It is connected to the epicoele of level-one cylinder body 1；3 bottom wall of second level cylinder body is equipped with the liquid of connection second level cylinder body cavity of resorption 9 and level-one cylinder body cavity of resorption 10
Pressure control valve 11；The bottom of portable pillar 5 is provided with one-way hydraulic control valve 6, and 7 He of circulatory mediator runner is offered in portable pillar 5
The hydraulic control runner 8 of one-way hydraulic control valve 6；The inlet of circulatory mediator runner 7 and the liquid outlet of one-way hydraulic control valve 6 connect
Logical, the hydraulic control mouth of one-way hydraulic control valve 6 is connected to the liquid outlet of hydraulic control runner 8, the inlet of one-way hydraulic control valve 6 and two
Grade cylinder body cavity of resorption 9 is connected to；The liquid outlet 14 of circulatory mediator runner 7 and the inlet 15 of hydraulic control runner 8 are separately positioned on portable pillar 5
Top.
Working principle of the present invention is summarized as follows:
One, setting prop: medium is entered in telescopic column level-one cylinder body cavity of resorption 10 by the first valve seat 12 on 1 outer wall of level-one cylinder body,
Push second level cylinder body 3 that portable pillar 5 is driven to rise together；The stopping when second level cylinder body 3 is raised to extreme higher position, at this time second level cylinder body 3
The hydraulic control valve 11 of bottom wall is opened, and emulsion enters in second level cylinder body cavity of resorption 9, and portable pillar 5 is pushed to rise, and portable pillar 5 is raised to
Stop when extreme higher position, entire telescopic column uphill process terminates.
Two, liquid is changed: while medium enters level-one cylinder body cavity of resorption 10 by the first valve seat 12 on 1 outer wall of level-one cylinder body,
Medium enters hydraulic control runner 8 by the inlet 15 on 5 top of portable pillar, and the hydraulic control mouth of one-way hydraulic control valve 6 is pushed to open, single
It starts to work to hydraulic control valve 6, the medium in level-one cylinder body cavity of resorption 10 enters second level cylinder body cavity of resorption by hydraulic control valve 11
