The four top beams of the utility model are connected into a group in parallel, the two top beams are mutually supported with the other two top beams in overlapping arrangement and alternative pre-displacement, thereby greatly improving support stability.
Description
Technical field
The utility model relates to the coal face support apparatus field, more particularly, relates in particular to a kind of hydraulic prop for sliding mine caps.
Background technology
In recent years, in the reform of stope working surface of coal mines support pattern, a kind of supporting product that is called hydraulic prop for sliding mine caps between hydraulic prop and fully mechanized mining supporter has obtained very big development, the structural shape of support also is of a great variety, but the mining face under mine situation varies, at high inclination-angle, in the application of big mining height and breaking roof work plane, it is poor to expose support stability, easily falls problems such as frame, and moving difficulty.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of and can adapt at high inclination-angle, the four beams combination in parallel hydraulic prop for sliding mine caps of big mining height and breaking roof work plane.
The utility model four beams combination in parallel hydraulic prop for sliding mine caps, be achieved by following technical proposals, comprise the back timber group, it is characterized in that, described back timber group is composed in parallel by back timber I, back timber II, back timber III, back timber IV, and adjacent back timber connects by bindiny mechanism; Described bindiny mechanism is by left and right guide pillar, left and right connecting rod, and left and right guide rod, left and right locking pin is formed; Described connecting rod two ends are provided with vertical each other horizontal guide and vertical guide; Left and right guide rod is individually fixed in end in opposite directions, adjacent back timber inboard, and horizontal guide passes left and right guide rod respectively, and left and right guide pillar is fixed by locking pin and back timber respectively, and vertically guide passes left and right guide pillar respectively; Between back timber I, the back timber II and between back timber III, the back timber IV propelling oil cylinder is set respectively, cylinder barrel one end of described propelling oil cylinder is hinged with back timber II, back timber III respectively, the other end and rod hinge connection.
The back timber side that the utility model is adjacent with described horizontal guide above and below is provided with sliding way and glide path respectively.
Guide pillar described in the utility model is fixed by guide pillar bearing and locking pin and back timber.Described guide rod is fixed by the guide bar receiver and the back timber at two ends.
The utlity model has following beneficial effect:
1. four back timber parallel connections are one group, and two back timbers and other two back timbers support each other, arranged crosswise, and alternately reach improves the stability that supports greatly.Can be applicable to high inclination-angle, the work plane of big mining height.
2. bindiny mechanism's one end is that the horizontal movement pair of guide rod and guide can be given a upset of back timber degree of freedom separately, makes each back timber in supporting the breaking roof process, not reason supported limit make between back timber the stuck and frame that can not fall of bindiny mechanism, move frame.
3. the advantage of the existing good integrity of the utility model support has the advantage of flexibility again.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is an attached view of the present utility model;
Fig. 3 is the A-A sectional view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, every back timber is supported by two hydraulic props in front and back 10,11.
As shown in Figure 2, back timber I of the present utility model, back timber II, back timber III, back timber IV be arranged in parallel, connect with bindiny mechanism between the adjacent back timber, and the connecting rod two ends are provided with vertical each other horizontal guide and vertical guide; Left and right guide rod 12,1 is individually fixed in end in opposite directions, adjacent back timber inboard, and horizontal guide passes left and right guide rod respectively, and left and right guide pillar 15,5 is fixed by locking pin and back timber respectively, and vertically guide passes left and right guide pillar respectively; Be provided with respectively between back timber I, the II and between back timber III, the IV and advance oil cylinder 9,13, advance cylinder barrel one end of oil cylinder hinged respectively at II, back timber III, the other end and rod hinge connection, and be connected respectively at back timber II, back timber IV with guide pillar by connecting rod, the horizontal direction guide of connecting rod and guide rod matched in clearance form the horizontal movement pair.Guide rod 1 is fixed with back timber by the guide bar receiver 8 at its two ends, and it is spacing that guide rod 1 and guide bar receiver 8 are established an end.
As shown in Figure 3, bindiny mechanism mainly is made up of guide pillar 5, connecting rod 2, guide rod 1, locking pin 6, sliding way 3, glide path 4; Guide pillar 5 is fixed with back timber by guide pillar bearing 7 and locking pin 6.Vertical guide is formed the pair that moves both vertically with guide pillar, and horizontal guide is formed the horizontal movement pair with guide rod, this secondary function that realizes frame that moves both vertically, the function that the realization of horizontal movement pair moves frame.The back timber side adjacent with horizontal guide above and below be fixedly sliding way 3, glide path 4 respectively, establishes certain clearance between slideway and connecting rod top and bottom.Both guaranteed that back timber has certain upset degree of freedom, limited back timber again and excessively overturns.
The utility model is realized its function by following action: at first back timber I, back timber III are by the hydraulic prop roof supporting, the hydraulic prop unloading retraction of back timber II, back timber IV, back timber II, back timber IV fall by the kinematic pair of connecting rod in guide pillar at this moment, break away from roof; Then, two propulsion cylinder fluid injection retractions drive back timber II, back timber IV step pitch of kinematic pair reach by connecting rod and upper and lower slideway, and the hydraulic support of fluid injection back timber II, back timber IV makes it support roof again; Thereafter back timber I, back timber III advance oil cylinder movement step same as described above to follow up by releasing, and be concordant with back timber II, back timber IV, finishes an actuation cycle.
The utility model can also have another kind of sequence of movement to be according to the work plane trend: back timber II, back timber IV at first support, and back timber I, back timber III move earlier, back timber II, back timber IV follow up subsequently, finish an actuation cycle.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
