At fully-mechanized mining working, hydraulic support moves when rising frame again behind the frame, sting frame, inclination mutually for the hydraulic support that prevents to be moved forward and adjacent hydraulic support, use and transfer rack device straightening hydraulic support, and make the back timber base parallel alignment of back timber, base and adjacent hydraulic support.It is to transfer the frame jack that existing hydraulic support moves accent rack device behind the frame, and this accent frame jack is fixed on the sidepiece of base of hydraulic support and perpendicular with described base.
The existing this hydraulic support of transferring the frame jack that has, whether view frame jack is not in running order, transferring the frame jack is to be fixed on the sidepiece of base of hydraulic support and perpendicular with described base all the time, even make hydraulic support like this when transferring the frame jack to be in off working state, also to occupy bigger space outerpace, cause the inconvenience of using.
The utility model content
Technical problem to be solved in the utility model provides a kind of hydraulic support of transferring the frame jack that has, and when transferring the frame jack to be in off working state, occupies less space outerpace, and is easy to use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of hydraulic support with accent frame jack, comprise base, on described base, be provided with hydraulic vertical prop, be provided with back timber on described hydraulic vertical prop top, at least one side at described base is provided with holding tank, in described holding tank, accommodate and transfer the frame jack, and an end of described accent frame jack is hinged in the described holding tank;
Rotate described accent frame jack, described accent frame jack produces in the described holding tank and is in the operating position; Turn round described accent frame jack, described accent frame jack draws in described holding tank.
Further, on described back timber, be provided with the location division, be used for after described accent frame jack produces in the described holding tank, described accent frame jack being limited to and perpendicular position, the side of described base at the sidepiece of described base.
Wherein, described location division is a bracing frame.A described end of described accent frame jack is hinged in the described holding tank by the articulated section that is fixed in the described holding tank; Described location division is fixed in the described holding tank, and described location division and described accent frame jack lay respectively at the both sides of described articulated section.
The utlity model has the hydraulic support of transferring the frame jack, when needing hydraulic support that straightening moved forward and adjacent hydraulic support, described accent frame jack is produced in the described holding tank and be in the operating position, utilize described accent frame jack to carry out straightening operation between adjacent hydraulic support; Behind the straightening end of operation, when maybe needing to carry out the straightening operation, described accent frame jack can be drawn in described holding tank.When transferring the frame jack to be in off working state, occupy less space outerpace like this, easy to use.
Description of drawings
Structural representation when Fig. 1 is contained in holding tank on the hydraulic support foundation for transferring the frame jack among the utility model embodiment;
Fig. 2 is the structural representation that has the utility model embodiment that transfers frame jack location division.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to shown in Figure 1, present embodiment has the hydraulic support of transferring the frame jack, comprise base 1, on described base 1, be provided with hydraulic vertical prop 2, be provided with back timber 3 on described hydraulic vertical prop 2 tops, be hinged with caving shield 4 with described back timber 3, described caving shield 4 is hinged by connecting rod 5 and described base 1, be hinged with waste rock board 6 with described caving shield, at least one side at described base 1 is provided with holding tank 7, in described holding tank 7, accommodate and transfer frame jack 8, and an end of described accent frame jack 8 is hinged in the described holding tank 7 by the articulated section 9 that is fixed in the described holding tank, transfer the base end of frame jack to be hinged in the described holding tank described in the present embodiment; Rotate described accent frame jack 8, described accent frame jack 8 produces in the described holding tank 7 and is in the operating position; Turn round described accent frame jack 8, described accent frame jack draws in described holding tank 7.
The operating position normally described accent frame jack 8 of described accent frame jack 8 wherein and the perpendicular position, side of described base 1, but the utility model is not limited to this, can determine to transfer the operating position of frame jack according to on-site actual situations.
The utlity model has the hydraulic support of transferring the frame jack, when needing hydraulic support that straightening moved forward and adjacent hydraulic support, described accent frame jack 8 is produced in the described holding tank 7 and be in the operating position, utilize described accent frame jack 8 to carry out straightening operation between adjacent hydraulic support; Behind the straightening end of operation, when maybe needing to carry out the straightening operation, described accent frame jack 8 can be drawn in described holding tank 7.When transferring the frame jack to be in off working state, occupy less space outerpace like this, easy to use.
Referring to shown in Figure 2, further, on described back timber, be provided with location division 10, be used for after described accent frame jack produces in the described holding tank, described accent frame jack being limited to and perpendicular position, the side of described base at the sidepiece of described base.Like this, make, keep the position stability of described accent frame jack, prevent it, improved the safety of operation from the operating position slippage utilizing described accent frame jack to transfer in the frame process.
Wherein, described location division 10 is for having the bracing frame of circular arc supporting surface, and support frame as described above is along having certain length with the perpendicular direction in the side of described base.Described accent frame jack is trapped in and perpendicular position, the side of described base by the circular arc supporting surface of support frame as described above.
Described location division 10 can be arranged on the outside of described holding tank 7, but in order to reduce the space outerpace that hydraulic support occupies as far as possible, described location division 10 is fixed in the described holding tank (as shown in Figure 2), and described location division and described accent frame jack lay respectively at the both sides of described articulated section.
Described location division 10 is not limited to above-mentioned bracing frame, can be the stopping means of other form also, as bearing pin, and limited block etc.
Wherein, described accent frame jack is a hydraulic jack.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
