Description

Technical Field

[0001] This utility model relates to the field of pipeline engineering technology, and in particular to a pipeline lifting tool for water conservancy projects. Background Technology

[0002] During the construction of water conservancy projects, pipelines need to be hoisted and moved. An existing pipeline hoisting tool (publication number CN 221971040U) is described. It features a limiting plate and a first lifting plate. The limiting plate is positioned at both ends of the pipeline. When one end of the pipeline is placed inside the limiting plate, a first spring exerts an inward pulling force on the first clamping plate, causing the first clamping plate to slide on the outside of the smooth rod to initially clamp the pipeline. Then, the first and second lifting plates are placed outside the pipeline. The second lifting plate is fixedly connected to the first lifting plate via a connecting column and fits over the outside of the pipeline. The telescopic rods and second spring inside the first and second lifting plates push the second clamping plate to clamp the pipeline, improving the stability of the pipeline during hoisting, reducing safety hazards, and being suitable for pipelines of different sizes, thus expanding the applicability of the hoisting tool. However, the operation of this hoisting tool is cumbersome, causing inconvenience in its use. Utility Model Content

[0003] The purpose of this utility model is to provide a water conservancy engineering pipeline lifting tool to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A hydraulic engineering pipeline lifting device includes a lifting ring with two steel wire ropes connected to its lower end. The lower ends of the steel wire ropes are connected to a lifting mechanism. The lifting mechanism includes a support body with an adjustment assembly for lifting pipes of different diameters. The support body includes a lifting base with a connecting seat fixed to its upper end. A vertical through groove is formed on the lifting base, containing two adjusting rods. A support roller is fixed to the lower part of each adjusting rod. The adjustment assembly includes a lead screw passing through the adjusting rod, with a first bevel gear at the end of the lead screw. A second bevel gear is located on one side of the first bevel gear on the lifting base, with a rotating shaft mounted at the center of the second bevel gear. One end of the rotating shaft passes through the lifting base and is fixed with a handwheel.

[0006] Further features: The adjusting rod is slidably connected to the through groove, the upper end of the adjusting rod protrudes from the hanger, and a limiting edge is provided.

[0007] Further configuration: The two lead screws in the through groove have opposite helical directions, and the lead screws are rotatably connected to the hanger.

[0008] Further configuration: The second bevel gear meshes with the first bevel gear and rotates, and the rotating shaft is rotatably connected to the hanger.

[0009] Further details: The support roller is welded to the adjusting rod, and the length of the support roller is less than the length of the hanging seat.

[0010] Further configuration: Support plates for supporting lead screws are installed on both sides of the rotating shaft inside the through groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By setting up the support body and adjustment components of the hoisting mechanism, the second bevel gear on the rotating shaft of the adjustment component meshes with the first bevel gear and rotates, driving the lead screws on both sides to rotate. The lead screws push the adjustment rods to move relative to each other, adjusting the support rollers between the adjustment rods to a suitable width to support the inner diameter of the pipe. Then, the support rollers on both sides are inserted into the inside of the pipe, and the end face of the pipe is aligned with the adjustment rods. By lifting the lifting rings and wire ropes upward, the pipe is lifted, improving the convenience of pipe hoisting operations. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a hydraulic engineering pipeline lifting tool includes a lifting ring 1, with two steel wire ropes 2 connected to the lower end of the lifting ring 1, and a lifting mechanism connected to the lower end of the steel wire ropes 2.

[0024] In this embodiment: the hoisting mechanism includes a support body, and the support body is provided with an adjustment component for hoisting different pipe diameters;

[0025] The support body includes a hanging base 3, with a connecting seat 31 fixed to the upper end of the hanging base 3. The connecting seat 31 is used to fix the wire rope 2, so that the lifting ring 1 is connected to the hanging base 3. A through groove 32 is vertically opened on the hanging base 3. Two adjusting rods 41 are set in the through groove 32. A support roller 42 is fixed to the lower position of the adjusting rod 41. The adjusting rod 41 is slidably connected to the through groove 32. The upper end of the adjusting rod 41 protrudes from the hanging base 3 and is provided with a limiting edge. The support roller 42 is welded to the adjusting rod 41. The length of the support roller 42 is less than the length of the hanging base 3. During hoisting, the support rollers 42 on both sides are inserted into the inside of the pipe, and the end face of the pipe is aligned with the adjusting rod 41. The pipe is lifted and moved by lifting the lifting ring 1 and the wire rope 2, which improves the convenience of hoisting the pipe.

[0026] The adjustment assembly includes a lead screw 43 passing through the adjustment rod 41. A first bevel gear 44 is provided at the end of the lead screw 43. A second bevel gear 46 is provided on the hanger 3 on one side of the first bevel gear 44. A rotating shaft 45 is installed at the center of the second bevel gear 46. A handwheel is fixed at one end of the rotating shaft 45 through the hanger 3. Support plates supporting the lead screw 43 are provided on both sides of the rotating shaft 45 in the through groove 32. The two lead screws 43 in the through groove 32 have opposite helical directions and are rotatably connected to the hanger 3. The second bevel gear 46 meshes with the first bevel gear 44 and rotates. The rotating shaft 45 is rotatably connected to the hanger 3. By rotating the rotating shaft 45, the second bevel gear 46 meshes with the first bevel gear 44, causing the lead screws 43 on both sides to rotate. The lead screws 43 push the adjustment rod 41 to move relative to each other, adjusting the spacing of the support rollers 42 between the adjustment rods 41 to the width of the upper part of the inner diameter of the support pipe, which facilitates the lifting and support of pipes of different specifications.

[0027] The working principle and usage process of this utility model are as follows: According to the inner diameter specification of the hoisting pipe, the second bevel gear 46 is driven to mesh with the first bevel gear 44 by rotating the rotating shaft 45, so that the lead screws 43 on both sides rotate. The lead screws 43 push the adjusting rods 41 to move relative to each other, and adjust the spacing of the support rollers 42 between the adjusting rods 41 to support the upper part of the inner diameter of the pipe. The support rollers 42 of the hoisting mechanism on both sides are inserted into the inside of the pipe, and the end face of the pipe is aligned with the adjusting rods 41. The pipe is lifted and moved by lifting the lifting ring 1 and the wire rope 2 upward.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
