Abstract
The utility model provides a combined type hydraulic supporting frame, which relates to a supporting and protecting device under coal mine. The utility model comprises top beams which connect with each other to be a whole body, the top beams are open box beams, sliding rails are arranged on the two sides of the top beams, and bidirectional hydraulic supporting pillars are arranged on the bottom of the top beams. A common movement connector is arranged between the sliding rails of the adjacent top beams, a hydraulic propelling cylinder is crossing arranged between the adjacent top beams, one end of the hydraulic propelling cylinder is fixed arranged on the posterior part of one of the two top beams, the other end is fixed arranged on the anterior part of the other top beam. So the utility model has advantages in that the supporting and protecting area is big, fast walking can be realized and the utility model can be used safely in the case of big inclination angle of working face.
Description
Technical field
The utility model relates to the support apparatus under the coal mine, particularly a kind of combination hydraulic support between fully mechanized mining supporter and cantilever support.
Background technology
The support apparatus of stope working surface of coal mines is the important step that is related to the coal miner production safety.The support apparatus that is used for the small mine stope at present mainly comprises little back timber and hydraulic prop, and each little back timber is independent separately.The little bar timbering area of this support apparatus is little, the speed of travel is slow, and has poor stability, the defective that labor strength is big.In the eighties, China develops several dissimilar cantilever supports, has played certain effect, and the easy sideslip of support, guidance quality are poor, the defective of operating difficulties but also exist simultaneously.The workload of adjusting the support sideslip in actual the use is very heavy, and the danger that the stope top caves in may occur in the adjustment course of work, and especially problem is more outstanding when the work plane of high inclination-angle uses.
Summary of the invention
The purpose of this utility model is that the supporting area at above-mentioned prior art back timber is little, the speed of travel slowly and the defective that can not use at large inclination working surface, a kind of combination hydraulic support that can address the above problem is provided.
The technical scheme taked of the utility model is to achieve these goals: a kind of combination hydraulic support, comprise back timber, described back timber is connected to each other as a whole, and described back timber is open body beam, and described back timber both sides are provided with slide rail, the bottom is provided with the bidirectional hydraulic pillar; Be provided with shared active connection between the slide rail of described two adjacent back timbers, stride between the two adjacent back timbers and be provided with the hydraulic pressure propulsion cylinder, rear portion, the other end that an end of hydraulic pressure propulsion cylinder is installed in one of them back timber is installed in the front portion of an other back timber.
Hydraulic pressure propulsion cylinder on the described same back timber is symmetrical arranged along the longitudinal centre line of this back timber.
The beneficial effects of the utility model are: compared to existing technology, the utlity model has the supporting area big, can realize the quick walking of support apparatus and the advantage that can under the large inclination working surface situation, use safely.
Description of drawings
Fig. 1 is the utility model combination hydraulic support normal operating condition structural representation;
Fig. 2 is the utility model combination hydraulic support reach status architecture schematic diagram;
Fig. 3 is that the back timber A described in the utility model combination hydraulic support is to zoomed-in view.
Among the figure: 1 back timber, 2 slide rails, 3 bidirectional hydraulic pillars, 4 active connections, 5 hydraulic pressure propulsion cylinders.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of combination hydraulic support shown in Fig. 1-2 comprises back timber 1.Back timber described in the utility model 1 is open body beam as shown in Figure 3, and described back timber 1 both sides are provided with slide rail 2, and described back timber 1 bottom is provided with bidirectional hydraulic pillar 3.A kind of combination hydraulic support shown in Fig. 1-2, described back timber 1 is connected to each other as a whole, be provided with shared active connection 4 between the slide rail 2 of described two adjacent back timbers 1, described active connection 4 can be hinges of the prior art or slide block, therefore the supporting area of combination hydraulic support is enlarged arbitrarily.Stride between the two adjacent back timbers 1 and be provided with hydraulic pressure propulsion cylinder 5, rear portion, the other end that an end of hydraulic pressure propulsion cylinder 5 is installed in one of them back timber is installed in the front portion of an other back timber.
Stressed evenly in order to guarantee same back timber 1, the hydraulic pressure propulsion cylinder 5 on the described same back timber 1 is symmetrical arranged along the longitudinal centre line of this back timber 1.Therefore guaranteed that the combination hydraulic support can walk fast, and guaranteed the safe handling of the utility model under the large inclination working surface situation.
Operating principle of the present utility model is: normal operating condition is interconnected to an integral body as shown in Figure 1 between the back timber.When the utility model need move forward, at first the bidirectional hydraulic pillar of second back timber in the left side is packed up as shown in Figure 2, this moment, the weight of the left side second back timber was transferred on the left side first, the 3rd back timber by active connection, two hydraulic pressure propulsion cylinders that start simultaneously on second back timber in the left side make its elongation, promote second back timber in the left side and move forward a step pitch, the bidirectional hydraulic pillar of second back timber in the left side falls and has supported this back timber.In like manner the 4th back timber in the left side moved forward a step pitch.After earlier the even number back timber being moved the position according to the rule that moves at interval.Hydraulic pressure propulsion cylinder on the 3rd back timber in the left side is resetted to shortening direction, and the 3rd back timber in the left side also moved forward a step pitch, in like manner according to the rule that moves at interval with all the odd number back timbers displacements except first back timber.First odd number back timber is by the method reach of traction.The reach of all back timbers is finished.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
