Description

Technical Field

[0001] The utility model relates to a pipe construction hoisting device under a floor slab. Background Art

[0002] When installing pipes under a roof slab, an electric hoist is usually used to hoist the pipes. The ropes are fixed on the pipes, and the electric hoist is operated to slowly lift the pipes. However, since there is a need for space between the hook head of the electric hoist and the ropes, when the distance between the pipe installation position and the floor slab is relatively close, the pipes cannot reach the installation position, and other equipment or manual labor is required to move the pipes to the installation position, resulting in reduced efficiency and increased safety risks. Therefore, a device with a simple structure, easy construction, strong stability, high safety, and convenient for pipe hoisting is needed to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies of the above prior art and provide a pipe construction hoisting device under a floor slab.

[0004] A pipe construction hoisting device under a floor slab includes a crane and a hoisting platform. The hoisting platform fixes the pipes on the upper end surface of the hoisting platform through fixing parts, and the ropes of the crane are connected to the hoisting platform. The connection points of the ropes and the hoisting platform are located below the axis of the pipes.

[0005] Preferably, the fixing part is a clamp, and the clamp is vertically fixed on the upper end surface of the hoisting platform.

[0006] Preferably, the clamp is a U-shaped part, and both ends of the U-shaped part are fixed on the upper end surface of the hoisting platform.

[0007] Preferably, the number of hoisting platforms is at least two.

[0008] Preferably, two upper lifting lugs and two lower lifting lugs are provided on the hoisting platform. The upper lifting lugs are welded on the upper end surface of the hoisting platform, and the two upper lifting lugs are located on both sides of the clamp. The two lower lifting lugs are welded on both sides of the bottom of the hoisting platform.

[0009] Preferably, the hoisting platform is of a cuboid structure, and the hoisting platform is welded by 12 channel steels to form a cuboid frame.

[0010] Preferably, reinforcing ribs are provided between a set of opposite sides of the upper end surface, lower end surface, front end surface, and rear end surface of the hoisting platform.

[0011] Beneficial effects: Compared with the prior art, in the utility model, the pipeline is placed above the hoisting platform, the pipeline is fixed by a clamp, and then the rope is fixed on the lifting lug plate. With the limited lifting height of the hoisting rope, the lifting height of the pipeline is increased, the distance from the floor slab is shortened, and the pipeline can be quickly installed under the floor slab. The overall strength of the hoisting platform is strengthened by the reinforcing ribs, and the lifting lugs are fixed on the hoisting platform by welding to ensure firmness even under stress.

[0015] To deepen the understanding of the utility model, the following will further elaborate on the utility model in combination with embodiments and drawings. The embodiments are only used to explain the utility model and do not constitute a limitation on the protection scope of the utility model.

[0016] As Figure 1-2 shown, hoisting platform 1, upper lifting lug 2, lower lifting lug 3, clamp 4;

[0017] A pipeline construction hoisting device under the floor slab includes an electric hoist and two hoisting platforms 1. The hoisting platform 1 is of a cuboid structure and is welded by 12 channel steels to form a cuboid frame. These 12 channel steels are equivalent to the edges of the cuboid. Reinforcing ribs are provided between a set of opposite sides of the upper end face, lower end face, front end face, and rear end face of the hoisting platform 1, and the reinforcing ribs are parallel to the left and right end faces of the hoisting platform 1.

[0018] The hoisting platform 1 fixes the pipeline on the upper end face of the hoisting platform 1 through a fixing member. The rope of the crane is connected to the lifting lugs on the hoisting platform 1. There are two upper lifting lugs 2 and two lower lifting lugs 3 on the hoisting platform 1. The upper lifting lugs 2 are welded to the upper end face of the hoisting platform 1, and the two upper lifting lugs 2 are located on both sides of the clamp 4. The two lower lifting lugs 3 are welded to both sides of the bottom of the hoisting platform 1.

[0019] The steel pipe is fixed on the upper end face of the hoisting platform 1 by the clamp 4. The connection point of the rope and the hoisting platform 1 is located below the axis of the pipeline. The clamp 4 is perpendicular to the upper end face of the hoisting platform 1. The clamp 4 is a U-shaped member, and both ends of the U-shaped member are inserted into the mounting holes on the reinforcing ribs of the upper end face of the hoisting platform 1. The clamp 4 is located between the two lifting lugs.
