Description
Technical Field
The utility model belongs to the technical field of hydraulic support, concretely relates to well formula end support that is adapted to U-shaped canopy tunnel.
Background
The middle-mounted type end supports are arranged on two sides of a roadway in a fully mechanized mining roadway, the reversed loader is distributed in the middle, a roadway top plate is supported, and self-moving force is provided for the reversed loader through a pushing jack, so that the middle-mounted type roadway end hydraulic support device is an important mining device; meanwhile, the top of the fully mechanized mining roadway has various shapes, generally, the top of the fully mechanized mining roadway is a trapezoidal shed roadway, for the trapezoidal shed roadway, a double-row type end support is adopted for a general end support, an upper side support and a lower side support are symmetrically arranged, a self-carrying pushing device is arranged, the pushing device is connected with a transfer conveyor, and during working, alternate frame moving can be realized;
the double-row type end bracket is prevented from falling by an anti-falling jack between an upper top beam, a lower top beam and a base so as to ensure the stable support of the end bracket, and the double-row type end bracket is often applied to the support of a roadway with a level top plate and small fall; however, when the roadway is a U-shaped shed roadway, because the top plate is uneven, has a radian and has a large actual fall, the upper and lower wall end supports of the anti-falling jack are arranged only by adopting the top beam and the base, the top of the anti-falling jack is supported on the cambered surface, the anti-falling stability of the anti-falling jack is greatly reduced, when a common end support is used for supporting, the anti-falling and coal mining adaptability of the anti-falling jack is not enough to meet the end support requirement of the U-shaped shed roadway, and the simple arrangement of the top beam and the base is insufficient;
