Description

TECHNICAL FIELD

[0001] The utility model relates to a back moving structure of the bottom basket of the cantilever casting hanging basket. BACKGROUND

[0002] The prestressed concrete continuous beam of span is widely adopted to carry out the cantilever pouring construction by the hanging basket. The so-called hanging basket construction is to adopt the hanging basket method to carry out the in-situ segmented cantilever operation when pouring the cantilever beam bridge. It does not need to set up the support and does not use the large hoist. When the construction section intersects with the highway or water surface or the construction section is the cable-stayed bridge, the bottom basket after the completion of the construction becomes a problem, and the existing dismounting method is to connect the bottom basket with the side of the hanging basket, to move step by step when encountering the obstacle, so as to move the bottom basket to the area for dismounting. The scheme has the complicated steps and low efficiency. SUMMARY

[0003] The utility model solves the technical problems existing in the prior art and provides a back moving structure of the bottom basket of the cantilever casting hanging basket.

[0004] The utility model adopts the technical scheme that the back moving structure of the bottom basket of the cantilever casting hanging basket, the side wall of the both sides of the concrete box girder is equipped with the through hole for the screw rod to pass through, the outside of the both side walls is equipped with two pad blocks respectively, the outside of the two pad blocks is equipped with the hanging beam along the length direction of the concrete box girder, the both ends of the screw rod pass through the pad block and the hanging beam and are screw connected with the nut respectively, and the nut is screwed to fix the hanging beam to be arranged at the concrete box girder.

[0005] Among them, at least two pulleys are arranged on a hanging beam, and the two pulleys are arranged at intervals and fixedly connected by a hard connecting rod.

[0006] Among them, a driving device is further included, the driving device is connected with the pulley or the hard connecting rod, and the driving device drives the pulley to move.

[0007] Among them, the hanging rod is a threaded steel or a steel sling.

[0008] Among them, the screw rod is a threaded steel.

[0009] Among them, the driving device can be a jack, an inverted chain or an oil cylinder.

[0010] Among them, the hanging beam is an I-shaped steel or a T-shaped steel.

[0011] Compared with the prior art, the utility model has the beneficial effects that after the bottom basket in the utility model is separated from the hanging basket, the vertical stress is transferred to the hanging beam, the movement through the hanging beam is not affected by the external obstacles, and the construction operation efficiency is improved.
