Detailed description of the invention
In order to be illustrated more clearly in the present invention, below in conjunction with preferred embodiments and drawings, the present invention is described further.
Embodiment 1
As illustrated in fig. 1 and 2, parallel hydraulic support comprises the front standing pillar 9 of back timber 6 and below and back prop 10, and this three part is the most basic comprising part of parallel hydraulic support, and in the present embodiment, parallel hydraulic holder part also comprises joist 7 and advancing jack 8; Wherein, front standing pillar 9 and back prop 10 are hinged with back timber 6, and in structure, entire combination suspension moving hydraulic support is undefined structure, set cap 6 must pass through external force with the angle of front standing pillar 9 and back prop 10, and the frictional force such as, after back timber supports and between top board is maintained; In the present embodiment, parallel hydraulic support has set up base 1, back link 2, front rod 3, caving shield 4 and balancing pole 5, base 1, back link 2, front rod 3, caving shield 4 and balancing pole 5 constitute the rock-steady structure for cantilever support of the present invention, i.e. quadric chain.The stability principle of this mechanism is the rising of set cap and reduces track, be carry out along the twisted-pair cable straightway that quadric chain is given, and track is only; Therefore the rising of set cap or reduce vertical with pillar axes; Therefore the effect of bracket stable is reached; Wherein, base 1 is connected with two back props 10, and the active force of two back props 10 directly acts on base 1; Back link 2 and front rod 3 all simultaneously respectively with base 1 and caving shield 4 hinged, front rod 3 is on the top of back link 2, and base 1, back link 2, front rod 3, caving shield 4 constitute the stabilizing mechanism of a double leval jib jointly; The upper extreme point of caving shield 4 is articulated with the rear portion of back timber 6, the two ends of balancing pole 5 respectively with caving shield 4 and back timber 6 hinged, flexible caving shield 4 and the angle of back timber 6 of can making of balancing pole 5 becomes greatly or diminishes.Namely balancing pole limits the rotation around back timber rear portion and caving shield upper end thereof axle of set cap when pillar elongates or shortens, thus makes back timber effectively contact top board, and ensures stable under zero load of support.Like this, a kind of parallel hydraulic support with stabilizing mechanism just becomes self can keep stable hydraulic support in without external force situation.
Embodiment 2
As shown in Figures 3 and 4, front standing pillar 9 and the back prop 10 of the back timber 6 of parallel hydraulic support and below, this three part is the most basic comprising part of parallel hydraulic support, and in the present embodiment, parallel hydraulic holder part also comprises joist 7 and advancing jack 8; Wherein, front standing pillar 9 and back prop 10 are hinged with back timber 6, and in structure, cantilever support is undefined structure, the back timber 6 of parallel hydraulic support must pass through external force with the angle of front standing pillar 9 and back prop 10, and the frictional force such as, after back timber supports and between top board is maintained; Set up base 1, guide peg group 12 and waste rock board 13 in the present embodiment, guide peg group 12 constitutes the rock-steady structure for slippage bracket of the present invention with back timber 6 or waste rock board 13; Wherein, base 1 is connected with two back props 10, and the active force of two back props 10 directly acts on base 1; Guide peg group 12 comprises upper guide bush and lower guide rod; Lower guide rod in guide peg group 12 and base 1 are fixed together, and are elevated with the cylinder body of back prop 10 simultaneously; Upper guide bush in guide peg group 12 and back timber 6 are fixed together; Upper guide bush in guide peg group 12 also can be fixed together with waste rock board 13; Waste rock board 13 and back timber 6 are fixedly connected on top beam rear end; Upper guide bush in guide peg group 12 and lower guide rod are matched in clearance, guide rod and guide pin bushing must and only have along common axle to relative sliding, make back prop 10 remain vertical with back timber 6, therefore base 1, guide peg group 12 form stabilizing mechanism with back timber 6 or waste rock board 13.Like this, a kind of parallel hydraulic support with stabilizing mechanism just becomes self can keep stable hydraulic support in without external force situation.
In embodiment 1 and embodiment 2, if be applied in the work plane of inclination angle, when cantilever support back prop 10 is mentioned or support setting load is not enough, under gravity can vertical, cause support unstable.Be provided with stabilizing mechanism in parallel support of the present invention, ensure that stent strut 10 is vertical with set cap 6.Namely avoid support back prop 10 vertical, thus reduce the labour intensity of workman, increase the stability of support, increase work efficiency and safety
Obviously; the above embodiment of the present invention is only for example of the present invention is clearly described; and be not the restriction to embodiments of the present invention; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here cannot give exhaustive to all embodiments, every belong to technical scheme of the present invention the apparent change of extending out or variation be still in the row of protection scope of the present invention.
