Abstract
The utility model discloses a stepping type advanced supporting and hydraulic support. Two front frame hydraulic columns are uniformly arranged and connected between two front frame top beams and two front frame pedestals, and a front frame pull bar is arranged and connected between two front frame hydraulic columns. Two rear frame hydraulic columns are uniformly arranged and connected between two rear frame top beams and two rear frame pedestal, and a rear frame pull bar is arranged between the two rear frame hydraulic columns. A passing oil cylinder is arranged and connected between the front rack pedestal and the rear frame pedestal, a balancing oil cylinder is respectively arranged between the two front frame top beams and two rear frame top beams, and each hydraulic part is connected to a hydraulic pipe system. The stepping type advanced supporting and hydraulic support fully satisfies the explosion-proof requirements of a gas mine, and is simple in operation, high in slipping efficiency and safety performance and low in labor intensity.
Description
technical field:
The utility model relates to a kind of forepoling hydraulic support, especially relates to a kind of step type forepoling hydraulic support.
background technology:
China is the country of coal production maximum in the world, and fully-mechanized coalface quantity constantly increases, and particularly the highly efficient and productive work plane of large mining height is increasing.But the kind of the advance support rack in the tunnel up and down of work plane is less, and exists and can not adapt to large section roadway and arrange more difficult.According to < < safety regulations in coal mine > >, stipulate, within the scope of the leading pressure influence in all emergency exits of coal-face and junction, tunnel, must add strong supporting, and the length of strengthening supported laneway must not be less than 20m, mechanical coal mining work plane, the head-room within the scope of this must not be lower than 1.8m.Current support pattern adopts hydraulic prop to coordinate 1.2m hinged girder, and this support form labor strength is large, and efficiency is low, and has potential safety hazard.The disclosed a kind of combined guided slipping type forepoling hydraulic support of Chinese invention patent, publication number is 101338684B.The disclosed hydraulic support of this patent documentation adopts electrichydraulic control mode, the slip mode of a support inner column promotes the movement of support, safety factor is lower on the one hand for the problem that this support exists, because coal seam fully-mechanized mining working is High gas area, although electromagnetic valve adopts intrinsically safe circuit or explosion-protection equipment, also have potential safety hazard and exist wherein; On the other hand, the slippage that the support that it adopts is inner column, skidding distance is short, and sliding efficiency is low, causes hydraulic support stand efficiency low poor with safety.
utility model content:
The purpose of this utility model is to provide that a kind of sliding efficiency is high, the good step type forepoling hydraulic support of safety.
To achieve these goals, the utility model comprises: side arm back timber, after-frame back timber, side arm hydraulic vertical prop, after-frame hydraulic vertical prop, side arm pull bar, after-frame pull bar, side arm base, after-frame base, side arm operating valve, after-frame operating valve, balancing cylinder, pass oil cylinder, between two side arm back timbers and two side arm bases, evenly arrange and be connected with two side arm hydraulic vertical props respectively, between two side arm hydraulic vertical props, arrange and be connected with side arm pull bar, between two after-frame back timbers and two after-frame bases, evenly arrange and be connected with two after-frame hydraulic vertical props respectively, between two after-frame hydraulic vertical props, arrange and be connected with after-frame pull bar, between side arm base and after-frame base, arrange and be connected with passing oil cylinder, between two side arm back timbers and two after-frame back timbers, arrange and be connected with balancing cylinder respectively, each hydraulic unit is connected to hydraulic plumbing system.
In the time of need to moving forward supporting like this, operation side arm operating valve declines side arm hydraulic vertical prop and side arm back timber, now side arm back timber leaves top board and no longer bears pressure, operation is passed oil cylinder pushing side arm base and is moved forward, operate balancing cylinder simultaneously and prevent that hydraulic support from walking tiltedly, after side arm base puts in place, again operate side arm operating valve and make side arm hydraulic vertical prop and the rising of side arm back timber hold out against top board; Then operating after-frame operating valve declines after-frame hydraulic vertical prop and after-frame back timber, now after-frame back timber leaves top board and no longer bears pressure, operation is passed oil cylinder and is pulled after-frame base to move forward, operate balancing cylinder simultaneously and prevent that hydraulic support from walking tiltedly, after after-frame base puts in place, again operate after-frame operating valve and make after-frame hydraulic vertical prop and the rising of after-frame back timber hold out against top board.Because the utility model is without any electric component, can meet the requirement of explosion proof of gaseous mine completely, there is the features such as simple to operate, sliding efficiency is high, safety is better, labour intensity is low.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of the utility model structural representation.
