Abstract
A forestope with pre-support technology of roadway is provided, whose girder is connected with a thrust gear at its rear end and a shield beam with its gemel at the front end. Two connecting rods are hinged together with their one end respectively and are hinged with the ends of the girder and the shield beam with their another end separately; a sustain jack is hinged on the girder with its rear end and hinged with articulated points of the two connecting rods with its front ends. The utility model provides temporary big-roof area support for the exploitation of the mine roadway, which can support the top slab and improve the safety and the reliability; in addition, the auto-move forestope shortens the supporting time and boosts the exploitation degree; besides, hydraulic pressure cylinder is used for pushing, which makes the utility model has the advantages of rapid speed, easy and reliable operation, reducing of labor intensity and operators on site and ensuring the supporting quality.
Description
Technical field:
The utility model relates to a kind of lame advanced supporting forestope, for the mine laneway developing provides empty top zone temporary lining.
Background technology:
At present during the China's coal-mine roadway opening, its empty top zone adopts many forestopes (steel pipe or square steel) to be suspended on along roadway direction and visits on the top board to empty top zone, and top board is played support action, prevents that the top board roof fall from causing personal injury accidents.This supporting has following shortcoming: 1. forestope does not have setting load to the supporting of empty top zone, and security reliability is poor; 2. forestope is that point contacts with top board, can not the empty top zone top board effectively be protected; Moving forestope when 3. working must manually take off it from top board, suspension ring are taken off be installed on the next anchor pole, and the moving process time is long, complicated operating process, and the supporting activity duration is long, has reduced the excavation operation time.
The utility model content:
The purpose of this utility model provides a kind of lame advanced supporting forestope, solves the existing shortcoming of using when present coal mine roadway is opened up of interim forestope, and empty top zone is carried out safety, reliable, quick supporting.
The purpose of this utility model realizes as follows: this lame advanced supporting forestope has a girder that is suspended, the rear end of girder connects thrust gear, the front end hinge of girder connects caving shield, there are two connecting rod one ends hinged, the other end of two connecting rods is hinged on the end of girder and caving shield respectively, pin joint is in the bottom of girder and caving shield, has a support jack rear end to be hinged on the girder, supports the jack front end and is hinged on the pin joint of two connecting rods.Move by supporting the pin joint that jack drives two connecting rods, caving shield is around its pin joint swing with girder, makes the caving shield supporting push up in the tunnel or turn back.
Girder is suspended in midair by suspension apparatus, suspension apparatus is suspended on the top, tunnel by anchor pole, suspension apparatus is made of crossbeam, leading screw, holder axle, support roller, the crossbeam two ends are provided with leading screw, fixing holder axle on the screw of leading screw, the holder axle is gone up by the bearings support roller, and support roller is supported on the girder flank, and anchor pole is suspended in the crossbeam middle part.By rotating threaded shaft can adjust girder height and about, the front-back direction balance.
Thrust gear is a hydraulic cylinder, and an end is hinged on the girder, the other end by tailstock be supported on be in the girder rear portion with the fixing passing suspension ring in top, tunnel on.
At the girder rear portion protection cylinder is set, a protection cylinder part stretches in the endoporus at girder rear portion, and the protection cylinder rear end is supported on the tailstock of thrust gear, and the effect one of protection cylinder is that hydraulic cylinder is passed in protection, and the 2nd, can be to the auxiliary guiding of girder.
The advantage that this lame advanced supporting forestope has: 1. caving shield is risen during supporting roof, can give the top board setting load, effectively top board is carried out supporting, improved security reliability greatly; 2. the mobile employing of forestope has been shortened support time from moving mode, has improved Homes Using TV, can improve the roadway opening drilling depth greatly; 3. adopt HYDRAULIC CONTROL SYSTEM, advancing of the rise of its caving shield, beam body all advances by hydraulic cylinder, and speed is fast, and operation is simple and reliable; 4. alleviate labor strength greatly, reduced site operation personnel's quantity, improved supporting quality.
