Hoisting device

Technical Field

The utility model relates to the technical field of hoisting of reinforcement cages, in particular to a hoisting device.

Background

The cast-in-situ bored pile is widely applied to projects such as urban deep foundation pit maintenance, bridge structural piles and the like due to the factors of low noise, simple pile forming process and the like. The conventional bored pile reinforcement cage generally adopts round steel as a hanging rib, each bored pile needs to calculate the length of the hanging rib according to the elevation of the pile top and the elevation of a working face, and the hanging rib is generally welded with a main rib of the reinforcement cage. Hang muscle length fixed, if meet special circumstances and need adjust when hanging the muscle, must cut off original hanging the muscle earlier, weld again after the adjustment length, change inefficiency causes whole engineering time extension. The special conditions mainly include that the designed top surface of the cast-in-place pile is often far away from the ground, and the empty drill is long in length, so that the steel reinforcement cage can float upwards in the concrete pouring process, and the length of the hanging rib needs to be adjusted too much. The length of the hanging bar is too large or too small and needs to be adjusted due to calculation errors of constructors. As the steel reinforcement cage hanging platform sinks, the length of the hanging steel reinforcement calculated and processed according to the original elevation needs to be adjusted if the hanging steel reinforcement is too large or too small. The welding time of the lifting ribs is often longer, and in the process, the quality of formed holes can be influenced, the problems of hole wall collapse, hole shrinkage or hole expansion and the like occur, and then the quality of the poured pile foundation is poor.
