Described column is connected with the control valve group by high-pressure oil pipe with jack.
Be covered with rail on the channel-section steel of described two slideway middle parts.
Compared with prior art, because the utility model is a frame construction independently, it is not supporter with the roof, therefore during hoisting heavy, can not cause load, can safeguard roof greatly to roof rock mass, manipulate safety, the accuracy height of butting member, assembling speed is fast, the production efficiency height.
The explanation of accompanying drawing drawing
Fig. 1, the 2nd, structural representation of the present utility model.
Fig. 3 is the utility model hydraulic control system figure.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Design philosophy of the present utility model is, uses hydraulic principle, and flexible by hydraulic cylinder lifts by crane, moves, dock the member of the hydraulic support of the transportation of disintegrating, and finishes assembling, thus the mechanized that the realization coal mine underground hydraulic support frame is assembled.As Fig. 1, Fig. 2, the utility model is a frame construction independently, and lifting beam is the casing that is welded into steel plate, is divided into two post lifting beams and four post lifting beam two parts, is referred to as two post beams 1 and four post beams 2.But six columns, the 4 usefulness bearing pins of bi-directional expansion are connected with lifting beam 1,2, are supported under the lifting beam 1,2, utilize the flexible of oil cylinder, realize the lifting of lifting beam 1,2.The bottom of column 4 is piston shoes, and the bottom of piston shoes is slideways 8.The jack of four 1.6m strokes is separately fixed at the utility model two bottom sides, finishes vertically moving of two post beams 1 and four post beams 2.The jack 6 with the 0.42m stroke of removable steel bushing is equipped with in four post beams, 2 ends, and in the steel bushing outside weldings Heave Here is arranged, and utilizes jack 6 to realize laterally moving of Heave Here.By the side of two post beams 1 and four post beams 4, be respectively equipped with pulley 7 and tensioner jack 5, realize the lifting of weight by the pulley 7 of wire rope and Heave Here.As Fig. 2, the bottom of slideway 8 is lined with on the channel-section steel 8 of middle part of No. 16 long channel-section steel 8, two slideways 8 of 3.4m and is covered with rail 9, and rail 9 is connected with channel-section steel 8 usefulness bolts, and channel-section steel 8 bottoms are seat earth.As Fig. 3, the operating valve set 3 of controlling this device is installed on the slideway 8, and operating valve set 3 is formed nine reversal valve groups by A, B, C, D, E, F, G, H, J, forms four reversal valve groups by K, L, M, N.Their title is to draw about A is, B is left front drawing, and C is right back drawing, and D is right front drawing, and E is for drawing on the back, and F moves on preceding, and G is push-and-pull, and H is two rear pillars, and J is two front pillars, and K be that the Zola is tight, and L be that strain on the right side, and M is push-and-pull, and N is two posts.Column, jack are connected with operating valve set 3 with high-pressure oil pipe, and as Fig. 3, operating valve set 3 is connected with liquid pump by high-pressure rubber pipe.Oil cylinder all be furnished with one way valve 11, safety valve, have also be furnished with synchronous valve 12 and restricting element.
The course of work of the present utility model: the utility model is arranged near the upper outlet of coal-face under the coal mine, and its task is that the gross weight of the transportation of disintegrating is assembled at the large hydraulic support more than 14 tons.Its method is through the track of this bottom of device, the mine car that transports the hydraulic support member to be transported in this device.Because oil cylinder of the present utility model, jack all are connected with the high pressure liquid pump by high-pressure rubber pipe, control valve, with the high-pressure emulsion is power, the handle of manipulation valve, can realize the flexible of oil cylinder and jack, finish lifting, whereabouts, mobile, thereby realize the butt joint and the assembling of support element the hydraulic support member that is transported to.In the course of work of this device, be furnished with synchronous valve 12 because of oil cylinder, can realize moving synchronously; The translation jack has choke valve, and can control it and rest on any desired location, thus the accuracy height of butting member, the assembling speed height.
The operating principle of the utility model hydraulic system: as Fig. 3, high pressure liquid enters two groups of reversal valve groups simultaneously by the P mouth, when operating four reversal valve group K, L, M, N, during two post N action, can operate two column valve N.During right feed flow, high pressure liquid stretches out two post beams by right bit synchronization valve 12 and by one way valve 11, and the liquid of withdrawal is got back to valve group O mouth by left bit synchronization valve 12.During as left side position feed flow, high pressure liquid is by synchronous valve and open column one way valve 11 two post beams are descended, and the liquid that stretches out is got back to the O mouth by the one way valve of opening 11 through synchronous valve 12.
When nine reversing group valve four posts actions of need operation, get final product four posts, one biconditional operation, also can two front pillars or two rear pillars, one biconditional operation, guarantee the synchronism of four post beams, as Fig. 3, during left feed flow of two preceding column valve J, high pressure liquid descends two front pillar beams by synchronous valve 12, and during the feed flow of right position, high pressure liquid rises two front pillar beams by synchronous valve 12 and one way valve 11, when if the handgrip of two front pillar beams and two rear pillar beams is operated simultaneously, four post beams are descended simultaneously or rise to make the horizontal lifting of four post beam maintenances.Same other jack action is identical with it, opens one way valve 11 during the feed flow of promptly left position and enters the jack epicoele.And liquid is returned in another chamber, and by the one way valve of opening 11, liquid is returned at the O mouth place that reversal valve enters into the valve group.
Member of the present utility model is bearing pin connects except that minority, and all the other all are that bolt connects.
