The purpose of this utility model is: in order to overcome the deficiencies in the prior art, move support thereby provide a kind of whole classification great-leap-forward easy to use to go on foot.
The technical solution adopted in the utility model is: a kind of whole classification great-leap-forward step is moved support, include one group of front support beam, one group of rear support beam, before, the column that connects under the rear support beam, hydraulic cylinder and hydraulic control circuit, front support beam and rear support beam are articulated and connected, the left side of front support beam, be provided with front-slider and rear slider between the right front beam, described column upper end is provided with single-acting formula hydraulic cylinder, column lower end is connected with inverse-T-shaped post boots, the left end of described front-slider is fixedly connected with left front beam, right-hand member and right front beam are slidingly connected, the left end of rear slider and left front beam are slidingly connected, right-hand member is fixedly connected with right front beam, front, be connected with the telescopic frame hydraulic cylinder that moves between the rear slider.
Be connected with free slide block between the rear support beam, the two ends of described free slide block are slidingly connected with the left and right back rest of rear support beam respectively.
Front-slider, rear slider and free slide block consist of by a block plate or the steel plate Combination Welding more than consists of, and the inboard of two groups of brace summers is provided with slideway.
Be welded with " π " shaped steel on the rear support beam soffit.
The beneficial effects of the utility model are:
1, the whole classification great-leap-forward step of the present utility model is moved support, and the step is moved support across above elevating conveyor, and two parallel fully mechanized coal face face end supports of back timber, pillar are near the elevating conveyor both sides, and having solved lower pair lane does not have to go on foot the history of moving support.
2, the whole classification great-leap-forward step of the present utility model is moved support, and the step moves the support power section and is arranged on the back timber, has cancelled structure of bottom girder.Structure is upper pays the lane step to move support simple and clear.After moving in the power section, be convenient to the mechanician and safeguard, be found easily when the problem such as leakage is arranged.
3, the whole classification great-leap-forward step of the present utility model is moved support, back timber adopts long and short beam to cooperate, the longest back timber 7.5m, short beam 4.3m, the recovery of lower tail lane π section steel beam is convenient in the recovery space that has increased tail lane π section steel beam, greatly alleviated the labour intensity that reclaims the worker, effectively raise and adopt the face advance support in tail lane recovery reusability, by original less than 60%, reached 100%.
4, the whole classification great-leap-forward step of the present utility model is moved support, and supporting intensity obviously increases, the drift section deflection be improved significantly, stopped secondary and expanded the input of repairing extra worker, improved personnel's work efficiency.
5, the whole classification great-leap-forward step of the present utility model is moved support, and the step moves support and all adopts hydraulic control, is convenient to integrated operation, has reduced timberer's labour intensity, has improved security performance;
6, the whole classification great-leap-forward step of the present utility model is moved support, the post footwear that pillar below pad is established, and Area of bearing is large, has effectively prevented phenomenon at the bottom of the column drill, has guaranteed head-room, has improved supporting intensity and safety factor.
