Detailed description of the invention
To be described in further detail the utility model embodiment below.
Novel many logical pieces of hydraulic support of the present utility model, its preferably detailed description of the invention be:
Comprise five spray interfaces, five times liquid interfaces, five feed liquor interfaces, described spray interface, time liquid interface are from the feed liquor interface cross section that three in these novel many logical pieces are different respectively;
Described five spray interfaces communicate with each other, its at the middle and upper levels 2 interfaces connect frame internal spraying sebific duct, middle 2 interfaces connect spraying hose between frame, 1 little interface of bottom surface is independent spray interface;
Described five are returned liquid interfaces and communicate with each other, its at the middle and upper levels 2 interfaces connect frame internal liquid return sebific duct, middle 2 interfaces connect and between frame, return sol pipe, 1 little interface of bottom surface be time liquid interface separately;
Described five feed liquor interfaces communicate with each other, its at the middle and upper levels 2 interfaces connect feed liquor sebific duct in frame, middle 2 interfaces connect feed liquor sebific duct between frame, 1 little interface of bottom surface is independent feed liquor interface.
2, the upper strata interface of described five spray interfaces, five return 2, the upper strata interface of liquid interface and 2, the upper strata interface of five feed liquor interfaces is horizontally disposed with;
2, the middle level interface of described five spray interfaces, five return 2, the middle level interface of liquid interface and 2, the middle level interface of five feed liquor interfaces is tilted to lower setting;
1 little interface of the bottom surface of described five spray interfaces, five return 1 little interface of bottom surface of liquid interface and 1 little interface of the bottom surface of five feed liquor interfaces arranges downwards.
2, the upper strata interface of described five spray interfaces, five return 2, the upper strata interface of liquid interface and 2, the upper strata interface of five feed liquor interfaces is provided with the step of playing U-shaped card.
Specific embodiment:
As shown in Figures 1 to 4, these novel many logical pieces have 15 interfaces, comprise five spray interface A1～A5, five times liquid interface B1～B5, five feed liquor interface C1～C5.Spray interface, time liquid interface and feed liquor interface respectively on novel three varying cross-sections that lead to pieces more.
Five spray interface A1～A5 communicate with each other, its at the middle and upper levels 2 interface A1, A2 be used for connecing frame internal spraying sebific duct, middle 2 interface A3, A4 are used for connecing spraying hose between frame, 1 little interface A5 of bottom surface is independent spray interface;
Five are returned liquid interface B1～B5 and communicate with each other, its at the middle and upper levels 2 interface B1, B2 be used for connecing frame internal liquid return sebific duct, middle 2 interface B3, B4 are used for connecing and between frame, return sol pipe, 1 little interface B5 of bottom surface be time liquid interface separately;
Five feed liquor interface C1～C5 communicate with each other, its at the middle and upper levels 2 interface C1, C2 be used for connecing feed liquor sebific duct in frame, middle 2 interface C3, C4 are used for connecing feed liquor sebific duct between frame, 1 little interface C5 of bottom surface is independent feed liquor interface.
6 interface A1, A2, B1, B2, C1, the C2 on upper strata are horizontally disposed with, and are provided with step, and step is for playing U-shaped card;
6 interface A3, A4, B3, B4, C3, the C4 in middle level are tilted to lower setting;
3 little interface A5, B5, C5 of bottom surface arrange downwards.
Application the utility model, when support drops to below certain altitude, the interface that connects sebific duct between frame is blocked by adjacent stent and cannot connect while supplying back sol pipe, can realize support feed flow by little interface C5 below, thereby guarantee support still can be realized exercises, facilitate support operation.
Between these novel many logical piece framves, sebific duct interface is different with many logical pieces of the prior art, and the direction of 6 interfaces in its middle level is changed into being tilted to down by conventional horizontal direction and opens.The benefit of doing is like this, in the time that many logical pieces connect between frame sebific duct, between frame, sebific duct is also under oblique, can increase the horizontal range of sebific duct and back timber side guard board rear portion wider portion, and while ensureing that adjacent frame support reduces between back timber side guard board and frame sebific duct leave enough vertical distances.Greatly increased the deflection of sebific duct between frame, the cutting danger to sebific duct between frame can effectively avoid falling frame and move frame time, has increased the security reliability of downhole production.There is simple in structure, practical, safe feature.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
