Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction lifting devices, in particular to a water supply and drainage pipeline construction lifting device. Background Art

[0002] In water supply and drainage projects, pipes are important components. They not only need to be accurately installed at the specific designed location, but also need to ensure the tightness and durability of their connections. With the acceleration of urbanization and the development of construction technology, the water supply and drainage pipeline system has become more and more complex, and the difficulty of construction has also increased. In this context, the application of lifting devices for water supply and drainage pipeline construction is particularly important. The traditional water supply and drainage pipeline installation method mainly relies on manual handling and installation, which is not only inefficient, but also has high safety risks, especially in places where the construction is higher or deeper, the limitations of manual operations are more obvious. In addition, with the expansion of the project scale and the complexity of the construction environment, the difficulty of manual handling of pipes has also increased accordingly, which not only affects the construction progress, but may also affect the quality of pipeline installation.

[0003] Publication No. CN220886781U discloses a lifting device for pipeline construction, including a base and a self-locking wheel, wherein an angle adjustment device is arranged inside the base, a lifting device is arranged at the top center of the base, the lifting device includes a power unit and a lifting unit, and a lifting device is arranged at the outer end of the lifting device. When it is necessary to lift the pipeline, the lifting motor is started to drive the reciprocating screw to rotate, thereby driving the slide and the connecting rod on the surface of the reciprocating screw to move downward, so that the lifting device is landed, which is convenient for installing the pipeline. After the installation is completed, the lifting motor is reversed to lift the pipeline for installation. After the lifting device lifts the pipeline, the adjustment motor is started to drive the rotating shaft to rotate, and then the turntable is driven to rotate, thereby realizing the adjustment of the position angle of the pipeline, which is more convenient for the pipeline docking work. However, the prior art still has shortcomings:

[0004] 1. In the prior art, when fixing the pipeline, the pipeline needs to be placed inside the lifting ring first, the threaded rod is rotated to move the arc-shaped clamping plate downward, and then the pipeline is clamped and fixed. Although pipelines of different diameters can be clamped and fixed, after the pipeline is moved to the position where it needs to be docked, the pipeline still needs to be pulled out, and the pipeline cannot be directly aligned through the device, and the use steps are cumbersome.

[0005] 2. The prior art controls and adjusts the motor to drive the rotating shaft to rotate, and then drives the turntable to rotate. Although the position angle of the pipeline can be adjusted, when the position of the pipeline is adjusted, the inertia generated by the weight of the pipeline itself will cause the pipeline to continue to rotate, resulting in inaccurate position adjustment.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a water supply and drainage pipeline construction lifting device, comprising:

After the water supply and drainage pipes are moved to the position where they need to be placed and aligned, the forward and reverse screw rods are rotated in the opposite direction to control the adjusting rods to drive the connecting rod and the clamping rod to move away from each other to release the water supply and drainage pipes for placement, which is more convenient, labor-saving and easy to use.

[0015] 2. The utility model adjusts the position angle of the pipeline by installing a rotating mechanism. The drive box drives the rotation of the worm, which drives the mutually meshing worm wheels to rotate. The shaft rod drives the turntable and the water supply and drainage pipeline to move. The position angle of the pipeline can be accurately adjusted, and the self-locking effect of the worm wheel and the worm can be used to avoid the inertia of the pipeline from affecting the position and angle of the pipeline.
