Technical Field
The utility model relates to the technical field of hoisting, in particular to equipment for disassembling a hoisting shaft of a large-sized concrete precast column.
Background
At present, the construction method of the large concrete upright post mainly comprises two methods. One of the modes is a traditional cast-in-place concrete mode, and concrete pouring is carried out after the upright post steel bar template is completed in the vertical direction; the other is to fix the mould and cast the mould in sections. The first method has the advantages of more high-altitude operation, poor construction safety, inconvenient vibration, easy occurrence of quality problems such as honeycomb pitting surface and the like; the second method has more construction joints, poor appearance quality and influences the service life. Based on the current construction situation of the large-scale concrete upright post, the technical process of prefabricating the whole upright post and then hoisting is developed, and the hoisting process needs to adopt a hoisting shaft to penetrate the prefabricated post. After the prefabricated column is lifted, because the lifting shaft used for lifting is heavy in weight and long in length, manual detachment cannot be directly carried out at high altitude, and when the hanging basket is used at high altitude, people and the lifting shaft are positioned in the hanging basket, so that a large potential safety hazard exists.

The utility model adopts the technical proposal for solving the technical problems in the prior art that: the large-scale concrete precast column hoisting shaft dismounting device comprises a crane, a chain block and an auxiliary support, wherein the auxiliary support is provided with a supporting structure which is propped against the side surface of a precast column, the middle position of the top of the supporting structure is connected with the upper end of a top beam through a cross beam vertical to the supporting structure, the inner side of the top beam is provided with a lifting lug, the horizontal central line of the lifting lug coincides with the axis of the hoisting shaft, and the lifting lug is connected with the hoisting shaft through the chain block; the cross beam is hung on the crane.
Based on the scheme, the utility model also makes the following improvements:
the supporting structure is provided with a top horizontal supporting rod and two supporting legs which are vertically fixedly connected with the top horizontal supporting rod.
The top horizontal support rod is fixedly connected with the cross beam, and a reinforcing rib plate I is arranged between the cross beam and the top horizontal support rod.
The support structure is made of channel steel.
And a reinforcing rib plate II is arranged between the cross beam and the top beam.
The cross beam and the top beam are made of H-shaped steel.
The utility model has the advantages and positive effects that: through adopting the crane to hang auxiliary stand, utilize prefabricated post to provide the support, adopt the chain block to take out the hoist and mount axle, at demolish the in-process, hoist and mount axle is hung on the crane all the time, and operating personnel stands in the hanging flower basket, can separate hoist and mount axle and operating personnel well, avoid being in same hanging flower basket, greatly improved the security of hoist and mount. The hoisting shaft dismounting device is simple in structure and convenient to use, and can improve hoisting shaft dismounting efficiency.

Detailed Description
For a further understanding of the utility model, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings in which:
referring to fig. 1 to 4, a large-sized concrete precast column hoisting shaft dismounting device comprises a crane (not shown in the figure), a chain block 2 and an auxiliary support, wherein the auxiliary support 3 is provided with a supporting structure which is propped against the side surface of a precast column 1, the middle position of the top of the supporting structure is connected with the upper end of a top beam 3-2 through a cross beam 3-1 vertical to the supporting structure, the inner side of the top beam 3-2 is provided with a lifting lug 3-3, the horizontal central line of the lifting lug 3-3 coincides with the axis of a hoisting shaft 4, and the lifting lug 3-3 is connected with the hoisting shaft 4 through the chain block 2; the cross beam 3-1 is hung on the crane.
In the embodiment, the supporting structure is provided with a top horizontal supporting rod 3-4 and two supporting legs 3-5 vertically fixedly connected with the top horizontal supporting rod, and the structure is simple. The top horizontal support rod 3-4 is welded with the cross beam 3-1, and a reinforcing rib plate I3-6 is arranged between the cross beam 3-1 and the top horizontal support rod 3-4, so that the structure is stable.
