Abstract
The utility model relates to a flexible slipping hydraulic support system which comprises connected and combined flexible slipping hydraulic supports. Each flexible slipping hydraulic support comprises a top beam, a pushing jack, a sliding plate, a clamping device and a hydraulic pillar. The sliding plate is arranged at the abdomen of the top beam, and can slide relative to the lower plane of the top beam. One end of the hydraulic jack is connected with the sliding plate, and the other end thereof is connected with the top beam, and the clamping device is arranged on the sliding plate. The flexible slipping hydraulic supports are fixed on a flexible cable through the clamping devices and are combined into the flexible slipping hydraulic support system. By replacing overall rigid connection with flexible part connection, the flexible slipping hydraulic support system not only keeps the completeness of the supports, but also improves the adaptability of the supports to a top plate, and simultaneously, improves the stress state of the supports, and reduces the damage to the supports caused on concentrated internal stress. Simultaneously, sliding plate mechanisms in the supports are simple, move flexibly, have small friction resistance and high propelling efficiency, the requirement on the precision of distance among the supports is low, and is installation is very convenient.
Description
Technical field
The utility model relates to the hydraulic support that a kind of coal mining work plane is used, and relates in particular to a kind of flexible gliding hydraulic bracket system.
Background technology
In the existing slippage class support, major part all is support to be linked into an integrated entity form the rigidity support system, as the patent No. is 91221135.0, patent name is the disclosed a kind of support of the utility model of " step-by-step movement slippage bracket ", by side bar, central sill, pillar and hydraulic feed device are formed, central sill is positioned in the middle of the π shape side bar, side bar and central sill bottom are connected with two hydraulic props respectively, the back-up block that extends to both sides along the deck-siding direction is arranged at the bottom of central sill, the top of side bar has and the corresponding back-up block that extends to central sill along the deck-siding direction of central sill back-up block, when side bar falls, its back-up block drops on the back-up block of central sill, though this mode has increased the resistance to overturning of support, limited the flexibility of support, make support reduce for the compliance that top board changes.In addition, in the bigger work plane of high-dipping and length, support all is rigidly connected and makes that all internal stresss discharge nowhere between support, and the connection damage of components phenomenon of support often takes place, thereby influences the normal use of support.
The utility model content
The utility model purpose is to solve the defective of above-mentioned hydraulic support, support connects by compliant member and replaces the integral rigidity connection, the globality that had both kept support, improved the compliance of support again to top board, also improved the stress of support simultaneously, reduced because the damage that stress concentration causes support.
Specifically, the utility model is achieved through the following technical solutions: a kind of flexible gliding hydraulic bracket system is characterized in that: described mounting system is combined by gentle rope connection by flexible gliding hydraulic bracket.Described flexible gliding hydraulic bracket comprises back timber, passes jack, slide plate, clamping device and hydraulic prop.Slide plate is arranged at the back timber belly, can relative slip take place with the back timber lower plane.Pass jack one end and be connected in slide plate, the other end is connected in back timber, pass jack can make when flexible slide plate near or away from the back timber front end.Hydraulic prop vertically is installed on the back timber bottom surface, plays the effect of supporting flexible gliding hydraulic bracket, and when needs moved frame, hydraulic prop can shrink.Clamping device is installed on the slide plate, and the clamping device lower end is a closed-loop, and gentle rope passes the closed-loop that clamping device forms.Flexible gliding hydraulic bracket is fixed on the gentle rope by clamping device, is combined into flexible gliding hydraulic bracket system.
The quantity that is used to connect the gentle rope of flexible gliding hydraulic bracket can be chosen as one, two or many.When gentle rope quantity is two when above, each support of mounting system can be realized same moved further by slide plate.
By adjusting clamping device, make gentle rope be in the state that clamps or do not clamp, to obtain the different angle of inclination of required work plane.When clamping device does not clamp, only control gentle rope and do not deviate from the formed closed-loop of clamping device.
On the plane of slide plate, rolling member can be set, make the relative motion of back timber and slide plate contact surface more flexible.
Described flexible gliding hydraulic bracket system is connected to form by at least two flexible gliding hydraulic brackets.
The utility model advantage compared to existing technology is: sled mechanism is simple, flexible movements, and frictional resistance is little, the propulsive efficiency height.Range accuracy between support and support requires low, easy for installation.Work when stressed, flexiblesystem can the absorption portion internal stress, can reduce the damage of parts.
Description of drawings

Fig. 2 is the partial view at flexible gliding hydraulic bracket system front view clamping device described in the utility model place;
Fig. 3 is that the K of flexible gliding hydraulic bracket system front view described in the utility model 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, Fig. 2 and shown in Figure 3, mounting system is combined by three flexible gliding hydraulic brackets connections, each flexible gliding hydraulic bracket comprises back timber 1, passes jack 2, slide plate 3, clamping device 5 and hydraulic prop 6, slide plate 3 is arranged at back timber 1 belly, can relative slip take place with back timber 1 lower plane, the plane of slide plate 3 is provided with rolling member 7, makes back timber 1 more flexible with the relative motion of slide plate 3 contact surfaces.Pass jack 2 one ends and be connected in slide plate 3, the other end is connected in back timber 1, pass jack 2 can make when flexible slide plate 3 near or away from back timber 1 front end.Four hydraulic props 6 vertically are installed on the bottom surface of back timber 1, play the effect of supporting flexible gliding hydraulic bracket, and when needs moved described support, hydraulic prop 6 can shrink.Clamping device 5 is installed on the slide plate 3, is used to clamp gentle rope 4, and flexible gliding hydraulic bracket is fixed on the gentle rope 4 by clamping device 5, is combined into flexible gliding hydraulic bracket system.
When mounting system moves, support is carried out following operation: 1) shrink hydraulic prop 6, away from base plate, back timber 1 leaves face roof, passes through clamping device 5 and slide plate 3 supporting top beams 1 by gentle rope 4; 2) jack 2 is passed in elongation, makes back timber 1 along passing the direction slip that jack 2 extends; 3) back timber 1 extends hydraulic prop 6 after sliding into assigned address; What 4) repeating step 1-3 finished other supports in the mounting system moves the frame action; 5) shrink passing jack 2 all in the mounting system simultaneously, pass jack 2 drive slide plates 3, clamping device 5 and gentle rope 4 and move, so far finish an actuation cycle of mounting system along the direction that passing jack 2 extends.
