Description

Lifting device and lifting method for reinforcing reinforced concrete columns

technical field

The invention relates to the technical field of adding floors to buildings, in particular to a lifting device and a lifting method for reinforcing reinforced concrete columns.

Background technique

With the development of the times, the number of floors of the original buildings can no longer meet people's needs. Therefore, the houses in many areas in our country have been remodeled with additional floors, which saves trouble and effort, and brings good economic benefits. In real life, the floor is set above the base, and reinforced concrete columns are set between the floor and the base. In order to improve the engineering quality of the floor-adding renovation, it is necessary to remove the old reinforced concrete columns and install new reinforced concrete columns. During the demolition process of reinforced concrete, it is necessary to use a jack to separate the reinforced concrete column from the base, and use a lifting device to lift the reinforced concrete column to a suitable place.

The existing lifting device for reinforced concrete columns realizes the lifting of reinforced concrete columns by means of hoist and chain binding. However, when the reinforced concrete column is separated from the base, due to the instability of the center of gravity of the reinforced concrete column, during the lifting process of the reinforced concrete column In the middle, it is easy to cause the chain to shake, which will cause a safety hazard.

The column passes through the adjustable positioning area, and the inner surfaces of the two groups of movable plates are provided with positioning blocks that match the positioning slide rails.

By adopting the above-mentioned technical scheme, through the bonding between the movable plate and the reinforced concrete column, the positioning slide rail installed on the surface of the reinforced concrete column is positioned on the movable plate, and the hoist is used to wind up the chain, so that the reinforced concrete is placed on the two sets of movable plates. Do vertical upward lifting movement in the limited positioning area. Since the two sets of movable plates limit the movement track of the reinforced concrete, during the lifting process of the reinforced concrete, the horizontal swing of the reinforced concrete can be effectively avoided to strengthen the reinforced concrete. Improved stability.

Preferably, a bucket elevator is provided on the side close to the connection side between the supporting tire frame and the positioning plate, and a hopper that drives up and down along the supporting tire frame is provided on the bucket elevator, and the gap between the hopper and the positioning plate is connect.

By adopting the above technical scheme, the bucket elevator installed on the support frame can realize the up and down transmission of the hopper, thereby driving the positioning plate to move up and down on one side of the support frame. Due to the different heights of the reinforced concrete columns, it is necessary to The position of the positioning plate is adjusted up and down, so that the positioning plate is adjusted to a position below the height of the reinforced concrete column, so as to adapt to reinforced concrete columns of different heights, and has wider applicability.

Preferably, the positioning plate is provided with a driving group for driving two groups of the movable plates to perform relative synchronous movement on the positioning plate
