Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering equipment, in particular to a pipeline lifting device for water conservancy engineering. Background Art

[0002] Before constructing water conservancy pipelines, you first need to select suitable pipeline materials. Common pipeline materials include steel pipes, cast iron pipes, plastic pipes and concrete pipes. When selecting materials, factors such as the purpose of the pipeline, environmental conditions, load-bearing capacity and corrosion resistance should be considered. During the construction of water conservancy projects, the quality of the water conservancy pipeline connection can be improved by lifting the water conservancy pipeline to be connected to the connection position, thereby improving the sealing of the water conservancy pipeline;

[0003] The existing pipe lifting equipment for water conservancy projects includes a support base, on which a group of symmetrical arc-shaped support members are arranged. The pipes are placed in the arc-shaped support members to realize the lifting function, so that the water conservancy pipes can be connected or repaired. However, during the construction of water conservancy projects, there will be a need to install and repair pipes of different heights, and the arc-shaped support members of fixed height are difficult to move into the bottom of the pipe again to support and lift it after installation is completed or when maintenance is required. The application scope is narrow and it is inconvenient to use. Therefore, an adjustable pipe lifting equipment for water conservancy projects is needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the height is fixed and cannot be adapted to different maintenance and installation requirements, and provides an adjustable pipeline lifting device for water conservancy projects.

[0005] The top of the support leg is provided with a toothed structure, and the toothed structure is designed so that the support leg can move freely in the rotation on the support leg, and the toothed structure can be adjusted accordingly.

[0006] As an improvement, a group of lifting rods extending to the bottom end of the support base are symmetrically and slidably provided on the support base, the moving wheels are rotatably set at the bottom ends of the lifting rods, the top ends of the lifting rods are connected to a lifting plate located between the side panels, and the center of the top surface of the support base is provided with a hydraulic telescopic rod fixedly connected to the lifting plate, which facilitates the stable placement and fixation of the equipment.

[0007] As an improvement, a limit plate fixedly connected to the slide rod is provided between the side plates, and the lifting plate is located below the limit plate, which can limit the adjustment process so that the adjustment process of the left and right side plates remains balanced.

[0008] As an improvement, a plurality of stabilizing columns are evenly arranged around the bottom surface of the support base, and the stabilizing columns are close to the ground to improve the stability of the device.

[0009] The advantage of the utility model over the prior art is that the height position of the adjusting plate can be adjusted by cooperating with the adjusting screw and the adjusting screw hole, thereby realizing the adjustment of the height of the arc-shaped support plate on the load-bearing plate, so that the lifting equipment can adjust the lifting height according to actual needs to adapt to the requirements of different maintenance, repair or replacement operations.
