Utility model content
This utility model provides a kind of caving roof coal hydraulic support for exploiting half-edge coal seam.
The technical solution adopted in the utility model is as follows:
A kind of caving roof coal hydraulic support for exploiting half-edge coal seam, is made up of right part and left part;The right part includes Right part back timber, right part base, right column and left column;The left part includes left part back timber, left part base and back end beam;The right side Column and the left column are used to realize the right part back timber and left part back timber lifting;The back end beam and the left part top Beam rear end connects, and offers low level coal discharge outlet, for will fall within top coal above the back end beam from the body frame left part rear end Release.
In the above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam, the right part also includes quadric chain, For controlling the right part back timber and left part back timber lifting.
In the above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam, the left part back timber offers a high position and puts coal Mouthful, for the top coal above the left part back timber is released.
In the above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam, also including chute, for by the high position The top coal that coal discharge outlet is released is transported in transporting equipment.
The above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam also includes coal passing plate, connects with the transporting equipment Connect, for top coal is kept off in the transporting equipment.
In the above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam, the right part back timber include front stretching beam and Extensible canopy afterwards.
In the above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam, the left part back timber includes extensible canopy.
In the above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam, the front stretching beam and the extensible canopy are Integrally.
In the above-mentioned caving roof coal hydraulic support for exploiting half-edge coal seam, the left part back timber includes that left part back timber is covered Backplate, the left part base include left part base shielding plate, for preventing spoil or remaining coal in goaf from pouring in inside.
It is as follows by the way of this utility model carries out exploitation half-edge coal seam:
A (), in half-edge coal seam, across pitch direction level digs a tunnel as stope, face length I.e. span length, is determined by coal seam thickness.
(b) in work surface, across pitch direction arrangement caving roof coal hydraulic support, and the hydraulic pressure with other or same type Frame is applied in combination, and constitutes body frame and subframe, and on a left side, subframe stretches out body frame right part extension on the right side according to coal seam thickness needs to body frame The extensible canopy of contracting beam and rear extensible canopy and body frame left part.Transporting equipment is arranged in into rear portion.Body frame and subframe fulcrum each other, no Open close mistake pushes away subframe, draws body frame, moves in circles, realize that hydraulic support moves towards direction along work surface and moves from left to right, transports Equipment is moved prior to hydraulic support, and both moving step pitchs are identical.
C () hydraulic support body frame and subframe each circulation complete once to put coal process, Sub-Level Caving is completed by body frame left part. Coal releasing will be pushed up especially by circulation open and close high position coal discharge outlet and low level coal discharge outlet to realize, the top coal that high-order coal discharge outlet is released It is transported in transporting equipment by chute, low level coal discharge outlet is directly placed into coal is pushed up in transporting equipment.
Above-mentioned technical proposal of the present utility model has advantages below compared to existing technology:
(1) this utility model provide the caving roof coal hydraulic support for exploiting half-edge coal seam, due to be divided into right part and Left part two parts, right part are responsible for supporting and movement, and left part is responsible for putting coal and anti-cash, meanwhile, caving shield coal discharge outlet and transporting equipment Rear end is respectively positioned on, and transporting equipment is all shifted laterally, therefore, this utility model can realize half-edge coal seam machinery metaplasia Produce, production safety and improve production efficiency, and the reduction labor strength of high degree is effectively ensured.
(2) this utility model provide the caving roof coal hydraulic support for exploiting half-edge coal seam, due to body frame left part it is same When offer high-order coal discharge outlet and low level coal discharge outlet, and chute is installed, therefore, this utility model can effectively ensure that Sub-Level Caving That what is exploited puts coal efficiency and recovery ratio.
(3) caving roof coal hydraulic support for exploiting half-edge coal seam that this utility model is provided, as right part is provided with Former and later two extensible canopies, left part are provided with extensible canopy, therefore, this utility model can be suitable for Coal Seam Thickness Change, be effectively ensured Production safety.
