Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the steel reinforcement cage rotating boom device comprises: the steel bar cage lifting device comprises a support column 4 fixed on a factory building, a lifting arm 3 rotatably connected to the stand column, a connecting arm 2 with one end rotatably connected to the other end of the stand column and connected to the lifting arm 3, a supporting arm 5 connected between the connecting arm 2 and the lifting arm 3, a lifting mechanism fixed under the lifting arm 3 and driving a steel bar cage to move in the left-right direction, a traction rope connected to the lifting mechanism and sliding on the lifting mechanism, lifting ropes 7 connected to two ends of the traction rope, and hooks 8 arranged on the lifting ropes 7. Preferably, the hoisting mechanism is an electric hoist 6. The suspension arm 3 and the connecting arm 2 are supported in the middle by a supporting arm 5, and the connecting part of the suspension arm 3 and the connecting arm is anchored by a hinge joint 1.
Preferably, the support 4 is an i-steel support 4, the suspension arm 3 is an i-steel suspension arm 3, the connecting arm 2 is a square pipe steel connecting arm 2, the supporting arm 5 is a square pipe steel supporting arm 5, and the lifting rope 7 is a steel wire rope. Preferably, the arm length of the suspension arm 3 is 6m, and the hoisting weight is more than or equal to 1 ton.
The suspension arm 3 is anchored with the upright post through the articulated piece 1, and the support arm 5 is anchored with the upright post through the articulated piece 1; through the rotation of the suspension arm 3 and the left and right movement of the electric hoist 6, two suspension points at the lifting end of the steel reinforcement cage are stressed uniformly, the deformation of the steel reinforcement cage due to nonuniform stress is avoided, and the production quality is improved.
The length of haulage rope and wire rope needs to make the steel reinforcement cage minimum 1.8m height from the ground, and such design keeps the steel reinforcement cage other end not to contact with ground all the time, avoids steel reinforcement cage both ends to receive ground extrusion and lead to warping.
