The problem of lifting operation, provides a kind of limited headroom descending reinforcing cage lifting mounting device.
The utility model is achieved by the following technical solution: a kind of limited headroom descending reinforcing cage lifting mounting device,
Boom hoisting main body including being in truncated rectangular pyramids structure setting, boom hoisting main body successively include upper frame, bracket and bottom from top to bottom
Frame, bracket are symmetrically arranged inclination frame body, are provided with the first fixed pulley and the second fixed pulley being generally aligned in the same plane on upper frame,
The middle part of upper frame is arranged in first fixed pulley, and the end of upper frame is arranged in the second fixed pulley, and bracket is located at the one of the second fixed pulley
It is provided with hoist engine in side frame body, the wirerope of hoist engine is passed sequentially through to be connected with after the second fixed pulley and the first fixed pulley and be hung
Tool, suspender is for connecting steel reinforcement cage.
Upper frame includes the first square rack, and the first square rack upper middle position is fixed with two horizontal section steels, and two
It is fixed with connecting shaft in the middle part of horizontal section steel, the first fixed pulley is provided in connecting shaft.
Chassis includes the second square rack, is provided with two support rods in the plane where the second square rack.
It is fixed with horizontally disposed cross-brace between two adjacent brackets, cross-brace totally three, positioned at the two of lower part
Root cross-brace is for installing hoist engine.
The utility model needs to consign steel reinforcement cage to steel reinforcement cage setting point using hook machine before use, for subsequent steel
It is the lifting of muscle cage, easy for installation, the utility model need to be moved to stake holes top and make axle center and the stake holes of the first fixed pulley
Center is located at same vertical line.It need to guarantee that suspender can form effective connection with stirrup at the top of steel reinforcement cage simultaneously.
The utility model has the beneficial effect that compared with prior art
The utility model structure is simple, cost performance is high, and whole frame body height can be carried out according to the head room of corresponding position
Setting has prevented the high-order resistance phenomenon that may occur during lifting by crane steel reinforcement cage using crane.Meanwhile the utility model is grasped
Make it is easy, after suspender is transferred by hoist engine and is fixedly connected with steel reinforcement cage top by operator, then pass through hoist engine by its
Slowly lifting, whole operation only need 1~2 operator can be completed, greatly reduce construction cost.
