Abstract
A gangue-preventing device which is fully used for mining the inclined and sharp inclined coal bed and is arranged in the front of the hydraulic support and relates to the coal mine support equipments. The utility model substantially comprises a top beam, a pillar, a shield beam, a front connecting rod, a back connecting rod, a chassis, a scraper conveyer which is used in the mining face, a jack and a gangue preventing plate, and is characterized in that each scraper conveyer which is arranged in front of the hydraulic support is arranged with a gangue preventing plate. The utility model can keep the coal gangue which is cut down by the cutter and falls down from the roof outside the hydraulic support and thereby ensure the safety of operators and walkers. The utility model can be widely used in the mining of inclined and sharp inclined coal bed.
Description
Technical field
The utility model belongs to coal mining field of mechanical technique, particularly support apparatus in coal mine.
Background technology
According to the magnitude classification of seam inclination, seam inclination is divided into gently inclined seam, inclined seam, half-edge coal seam both at home and abroad.Seam inclination is being gently inclined seam below 25 °, is half-edge coal seam greater than 45 °.At present, tilt and half-edge coal seam is comprehensive adopts technology comprehensive to adopt technical development slow than gently inclined seam, and gap is bigger, main cause is that seam inclination is big, the rock of the local inbreak of bastard coal that the coal-face cutting coal machine is cut off and coal-face top board falls on coal-face base plate or transporter, can roll fast or fly along the coal-face incline direction and scurry.Because the out-of-flatness of coal-face base plate and bastard coal out-of-shape etc., coal, cash are in rolling fast or flying to scurry, at any time all might change in the hydraulic support that travel direction rolled into or scurried into fully-mechanized mining working, and be that personnel walk and the passage and the space of operation in the fully-mechanized mining working surface hydraulic support.In process of production, in case have coal, cash to roll into or scurry in the hydraulic support of fully-mechanized mining working, coal, cash roll fast downwards or fly to scurry along the passage of hydraulic support very easily again, and be untimely if personnel hide, will be therefore and injured or dead.Therefore, resolve bastard coal and fly to scurry that to hurt sb.'s feelings be to tilt and the comprehensive key of adopting of high-dipping.
At present, domestic research and the application that yet there are no inclination and high-dipping comprehensive mining hydraulic bracket frame front cash protective device.
Summary of the invention
The purpose of this utility model is the deficiency at existing comprehensive mining hydraulic bracket, a kind of inclination and high-dipping comprehensive mining hydraulic bracket frame front cash device are provided, have and to prevent that in the coal mining process coal, cash from rolling into or scurrying in the hydraulic support, guarantee the characteristics such as personal safety of operating personnel and pedestrian in the hydraulic support.
The purpose of this utility model is achieved in that a kind of inclination and high-dipping comprehensive mining hydraulic bracket frame front cash device, the back timber that mainly comprises hydraulic support, column, caving shield, front rod, back link, the scratch board conveyor of base and coal-face and jack, waste rock board, connector, junction plate etc., it is characterized in that on the scratch board conveyor in every hydraulic support the place ahead, setting up a waste rock board, fixedly connected with the top of 1～2 jack by connector respectively in the upper end of waste rock board, make waste rock board stretching out and shrinking and rise or descend with jack, and, in the stroke range of jack, regulate arbitrarily according to the needs of retaining cash.Each jack is fixed on the junction plate by bolt, and junction plate is affixed by the pipe cable supporting plate of bolt and scratch board conveyor.When the inclination angle of coal-face big needs retaining coal, cash, the waste rock board in every hydraulic support the place ahead is under the effect of jack, rise to the height that needs retaining coal, cash, prevent that coal, cash in the coal mining process from rolling into or scurrying in the hydraulic support, guarantee interior operating personnel of hydraulic support and pedestrian's personal safety, when needs were observed coal-cutting machinery or rib situation or do not needed to keep off coal, cash, the contraction by jack made waste rock board reduce convenient working.
The width of every waste rock board of the present utility model is 1000～2000mm, highly is that 400～1200mm, thickness are 8～70mm that its material is metal sheet or engineering plastics plate or bamboo scutum or wood based panel or rubber tile, and plate is provided with peep hole or atresia.The cylinder diameter of each jack is that 50～100mm, piston boit diameter are that 40～90mm, stroke are 400～1200mm.
Inclination that the utility model provides and high-dipping comprehensive mining hydraulic bracket frame front cash device, by set up a preceding waste rock board 11 in coal-face hydraulic support the place ahead, bastard coal and the coal-face wall caving that coal-face coal-winning machine 8 can be cut off, emit the bastard coal that pushes away under (collapsing), retaining is outside hydraulic support or in the transporter, the reason seam inclination is big and scurry in the hydraulic support to make bastard coal, and staff in the hydraulic support and pedestrian are caused security threat.Waste rock board 11 can by stretching out and contractile motion of jack 9, be realized the ascending, descending operation quickly and easily according to retaining cash need of work.The utility model can be widely used in the exploitation of inclined seam and half-edge coal seam.
