Description
Technical field
The utility model relates to a kind of open slope shaft excavation simple gantry crane device.
Background technology
When side slope vertical shaft adopts " raise boring machine method " to excavate, work progress is generally divided into 2 stages.1st stage carried out A216mm sprocket hole and A1.4m construction of pilot shaft for utilizing raise boring machine, and the 2nd stage digs A1.4m pilot shaft to design profile face.Divide according to vertical shaft diameter and dig for 1 time or 2 times.
After side slope vertical shaft completes the 1st staged construction task, manually need enter in pilot shaft and carry out the 2nd staged construction, namely pilot shaft digs.Because of construction time personnel, construction material traffic requirements, need dig in process arrange vertical lifting operation platform at pilot shaft above pilot shaft well head, conventional construction method is by arranging wheel crane or crane in bridge type.Though wheel crane can meet material vertical transport, operating personnel enters the safety hanging cradle in A1.4m pilot shaft, considers that construction safety cannot carry out vertical transport with wheel crane; Though crane in bridge type better can meet the traffic requirements of material, personnel, its construction preparation cycle is long, input cost is large.For solving this problem, we work out a kind of open slope shaft excavation simple gantry crane device.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of open slope shaft excavation simple gantry crane device.
The object of utility model is achieved in that a kind of open slope shaft excavation simple gantry crane device, it comprises column, crossbeam, suspension ring, fixed pulley, steel rope, earth anchor, suspension ring have two, be separately positioned on the position that crossbeam is different, safety hanging cradle A and safety hanging cradle B is connected to by fixed pulley and steel rope under two suspension ring, under safety hanging cradle A and safety hanging cradle B, corresponding first time digs face and digs face for the second time respectively, two steel rope one end connect earth anchor, and the other end is connected to winch A and winch B.
Above-mentioned crossbeam and column junction are provided with billet, are provided with skewed horizontal load between column and crossbeam, and column bottom is provided with balance in roll diagonal ligament.
Above-mentioned balance in roll diagonal ligament is fixed on the ground by oblique joint bar, and balance in roll diagonal ligament and oblique joint bar are welded to connect.
Above-mentioned skewed horizontal load two ends are all cut into inclined-plane and are welded into integral structure with column, crossbeam flange plate with 45 ° of angles respectively; Balance diagonal ligament one end is cut into inclined-plane and column flange plate is welded into integral structure with 30 ° of-45 ° of angles.
The utility model achieves following technique effect: be reliably connected with steel cable clamp by twin cable between suspension ring with fixed pulley.Oblique joint bar is set at bedrock surface, by dowel exposed parts and balance diagonal ligament firm welding, whole portal frame and basement rock is combined together; Draw in advance at crossbeam span centre position and establish steel rope, and land used is anchored on the opposite side of crossbeam, utilize positive and negative silk to regulate the tightness of steel rope, thus prevent that self steel rope in winch lifting process is stressed to be caused crossbeam span centre point horizontal displacement or be out of shape excessive to greatest extent; Hoisting system steel rope walks around fixed pulley, promotes or transfers safety hanging cradle and carry out vertical shaft Enlargement excavation.This device is simple to operate, safe and reliable, convenient to use, construction cost drops into little.
