Abstract
The invention relates to a pull-type suspension hydraulic support system, which is assembled by more than two pull-type suspension hydraulic supports. The pull-type suspension hydraulic support comprises a cross beam, a top beam, a hydraulic jack, a hydraulic prop and a guide device. The cross bean is arranged at the front end of the top beam; one end of the guide device is fixed on the cross beam, while the other end is in slide connection in the top beam; one end of the hydraulic jack is connected with the cross beam, while the other end is connected with the top beam, and through the stretching of the hydraulic jack, the top beam is driven to get close to or far away from the cross beam in the range of the guide device; and the bottom surface of the top beam is provided with a telescopic hydraulic prop. The cross beams of adjacent supports form an integrative rigid beam through a connecting device, and the top beams of the adjacent supports are connected with each other through a sliding block. When the pull-type suspension hydraulic support system performs frame-shifting work, the adjacent supports serve as supporting points for each other and move respectively, and the operation is simple and convenient. Simultaneously, the support system increases the operating spaces for workers and can effectively improve the working efficiency.
Description
Technical field
The present invention relates to a kind of coal mine hydraulic supporting, relate in particular to a kind of pull-type suspension hydraulic support system.
Background technology
The support apparatus in colliery is the critical facility that ensures coal miner safety, hydraulic support is a kind of support apparatus that generally uses in process of production at present, it has various ways, fully mechanized mining supporter by the realization walking that links to each other with transporter is arranged, the combined suspension moving hydraulic support of realizing walking by joist mechanism is arranged, have by self a plurality of part and alternately move the chevron top beam hydraulic rack of realizing walking, but all face problems such as complicated operation, equipment heaviness, workman's operating space is little in actual use.Also do not realize the support of walking at present by the combination crossbeam that connects adjacent two supports.
Summary of the invention
The invention reside in provide a kind of simple in structure, operate easy mounting system, combine by adjacent stent, can effectively reduce the thickness of support, increase workman's operating space simultaneously.
Specifically, the present invention is achieved through the following technical solutions: a kind of pull-type suspension hydraulic support system is characterized in that: described mounting system is combined by the pull-type suspension hydraulic support connection.Described pull-type suspension hydraulic support comprises crossbeam, back timber, hydraulic jack, hydraulic prop and guiding device.Guiding device one end is fixed in crossbeam, and the other end is slidingly connected in the back timber.Hydraulic jack one end is connected in crossbeam, and the other end is connected in back timber, hydraulic jack can make when flexible back timber in the guiding device restricted portion near or away from crossbeam.Hydraulic prop vertically is installed on the back timber bottom surface, and it is 3 to 6 that quantity is installed, and mainly plays the effect of supporting traction formula suspension moving hydraulic support, and when needs moved frame, hydraulic prop can shrink.
Pull-type suspension hydraulic support system is connected to form by the pull-type suspension hydraulic support more than at least 2, between the crossbeam of adjacent pull-type suspension hydraulic support linkage is housed, and makes each crossbeam form incorporate reinforcing beam.Simultaneously, be provided with slide block between the back timber of adjacent pull-type suspension hydraulic support, when back timber slides, play spacing and supporting role.
The guiding device of pull-type suspension hydraulic support can be chosen as one of girder construction, plank frame or rod shaped structure.
The present invention's advantage compared to existing technology is: simple in structure, effectively reduce the thickness of support, and increased workman's operating space simultaneously.

Fig. 3 is that the K of pull-type suspension hydraulic support system front view of the present invention is to view;
Fig. 4 is that the M of pull-type suspension hydraulic support system moving process schematic diagram of the present invention is to view.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
In conjunction with Fig. 1 and shown in Figure 3, mounting system is combined by three pull-type suspension hydraulic supports connections.Each pull-type suspension hydraulic support comprises crossbeam 1, back timber 5, hydraulic jack 2, hydraulic prop 7 and guiding device 4.Guiding device 4 one ends are fixed in crossbeam 1, and the other end is slidingly connected in the back timber 5.Hydraulic jack 2 one ends are connected in crossbeam 1, and the other end is connected in back timber 5, hydraulic jack 2 can make when flexible back timber 5 in guiding device 4 restricted portions near or away from crossbeam 1.Hydraulic prop 7 vertically is installed on back timber 5 bottom surfaces, and it is 4 that quantity is installed, and mainly plays the effect of supporting traction formula suspension moving hydraulic support, and when needs were mobile, hydraulic prop 7 can shrink.
Pull-type suspension hydraulic support system is connected to form by 3 pull-type suspension hydraulic supports, between the crossbeam 1 of adjacent pull-type suspension hydraulic support linkage 3 is housed, and makes each crossbeam 1 form incorporate reinforcing beam.Simultaneously, between the back timber 5 of adjacent pull-type suspension hydraulic support, be provided with slide block 6, when back timber 5 slides, play spacing and supporting role.
In conjunction with Fig. 2 and shown in Figure 4, when mounting system needs integral body to move frame, can carry out following operation to the pull-type suspension hydraulic support that is positioned at the centre position earlier: 1) shrink hydraulic prop 7, away from ground; 2) shrink hydraulic jack 2, back timber 5 is slided to crossbeam 1 direction, 6 pairs of back timbers 5 of slide block play and support and spacing effect in this process; 3) back timber 5 puts down hydraulic prop 7 after sliding into assigned address, and the frame that moves of so far finishing the centre position pull-type suspension hydraulic support moves.Adopting uses the same method again moves the pull-type suspension hydraulic support that is adjacent respectively, realizes that the integral body of mounting system moves.
