Description
Technical field
The utility model relates to the servicing unit of mine working temporary lining, especially a kind of adjustable front canopy hoisting ring.
Background technology
Forestope is generally adopted to carry out temporary lining during current tunnelling, forestope is connected by the anchor pole that front canopy hoisting ring and supporting are complete and is fixed and suspends in midair, complete the degree of safety that forestope temporary lining can improve work plane greatly fast, but it is uneven especially in the region that roadway surrounding rock is poor at top board, when spy beam carries out temporary lining before use, uneven owing to tunneling rear top board, the work of wearing beam expends time in longer, affects the life security of driving face operating personnel.
Summary of the invention
The purpose of this utility model is: provide a kind of adjustable front canopy hoisting ring, and it can improve and wears beam speed, and can well-tuned forestope position, to overcome the deficiencies in the prior art.
The utility model is achieved in that adjustable front canopy hoisting ring, comprise suspension ring framework, suspension ring framework is square shape structure, anchor pole attaching nut is provided with at the top of suspension ring framework, a through hole is provided with in the bottom centre of suspension ring framework, in this through hole, be provided with adjusting nut, and be provided with the full-thread bolt through adjusting nut, the top of full-thread bolt is in suspension ring framework, its bottom is in outside suspension ring framework; Be provided with the rotation body of rod in the bottom of full-thread bolt, be provided with regulating platform on the top of full-thread bolt, be provided with plate regulating tank in the both sides of suspension ring framework, plate is through plate regulating tank.
Described suspension ring framework is connected by chain with plate.Such plate that can prevent is lost.
Owing to have employed above technical scheme, inner space of the present utility model is comparatively large, effectively can improve wear beam speed in the scraggly region of back, by regulating platform can effectively regulate forestope position, makes it more press close to top board.Solve the problem that general suspension ring are difficult to regulate forestope position, improve the safety of driving face.The utility model structure is simple, and easy to implement, with low cost, result of use is good.
