Description

Technical Field

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

[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing hydraulic engineering projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways to achieve their objectives. During the construction of hydraulic engineering projects, pipelines need to be moved and installed, thus requiring pipeline lifting equipment for pipeline movement.

[0003] A search revealed that Chinese patent number CN221971040U discloses a pipe lifting device for water conservancy projects, including a fixed column. A slide rail is symmetrically fixedly connected to one side of the fixed column, and a first motor is fixedly connected to the adjacent side of the fixed column. A first rotating shaft is fixedly connected to the output end of the first motor. A slide groove is provided inside the slide rail, and a moving block is slidably connected to the inner side of the slide groove. A support frame is fixedly connected to the bottom of the moving block. A fixed plate and a first lifting plate are symmetrically arranged at the bottom of the slide rail. A limit plate is fixedly connected to one side of the fixed plate to facilitate clamping and fixing pipes of different lengths and prevent tilting or slippage out of the lifting device structure during hoisting due to the length of the pipe.

[0004] The aforementioned technology lacks self-locking protection. During pipeline hoisting, it relies solely on the power system to maintain the clamping state. The clamping components are affected by external forces such as shaking and vibration during hoisting, and the clamping may gradually loosen, causing the pipeline to tilt or shift, increasing the difficulty of adjustment, and even requiring work to be stopped midway for re-fixing, thus reducing construction efficiency. This design requires extremely high operational precision, and even slight improper operation may lead to clamping failure, increasing the risk and burden of manual operation, and weakening the reliability and safety of the device in pipeline hoisting in water conservancy projects.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1:

[0039] Please see Figure 1 - Figure 4 This embodiment provides a hydraulic engineering pipeline lifting tool that facilitates stable clamping of the outer side of a steel pipe. The specific concept is as follows:

[0040] The water conservancy project pipeline lifting tool includes a fixing plate 1. In addition, the water conservancy project pipeline lifting tool also includes a first clamping plate 2 and a second clamping plate 208 disposed below the fixing plate 1. The arc-shaped structure of the first clamping plate 2 and the second clamping plate 208 can firmly clamp the outside of the steel pipe to ensure the stability of the steel pipe clamping.

[0041] In order to drive the first clamping plate 2 and the second clamping plate 208, this embodiment provides a clamping component that can drive the first clamping plate 2 and the second clamping plate 208 to clamp the end of the steel pipe. At the same time, the clamping component can realize the self-locking design of the clamping of the first clamping plate 2 and the second clamping plate 208, which can further improve the stability of clamping and greatly increase the practicality of the device.

[0042] The clamping components of this embodiment include: a first rope 201 fixedly connected to the outer sides of both ends of the fixing plate 1 for lifting the device; a top plate 202 fixedly connected to the outer side of the end of the first rope 201; a first rotating arm 203 rotatably connected to the inner side of the bottom end of the top plate 202; a second rotating arm 204 rotatably connected to the inner side of one end of the first rotating arm 203, with the outer side of the bottom end of the second rotating arm 204 rotatably connected to the inner side of the top end of the first clamping plate 2; a third rotating arm 205 rotatably connected to the inner side of the rotating connection between the first rotating arm 203 and the second rotating arm 204 for pulling the first rotating arm 203 and the second rotating arm 204 to rotate; a connecting block 206 rotatably connected to the inner side of the ends of the two third rotating arms 205; and a vertical rod 20... 7 is fixedly connected to the outer sides of both ends of the top plate 202. The outer side of the vertical rod 207 is slidably connected to the inner sides of both ends of the first clamping plate 2. The first clamping plate 2 moves vertically on the outer side of the vertical rod 207. The outer side of the bottom end of the vertical rod 207 is fixedly connected to the second clamping plate 208. One side of the first clamping plate 2 and the second clamping plate 208 are provided with an arc-shaped structure for fitting and clamping the outer side of the pipe. The outer side of the top end of the top plate 202 is equipped with a telescopic cylinder 209. The outer side of the end of the telescopic cylinder 209 is connected to the upper surface of the connecting block 206 for driving the connecting block 206 to move in the vertical direction. The outer sides of both ends of the top plate 202 are fixedly connected to the spring 210. The outer side of the bottom end of the spring 210 is fixedly connected to the outer sides of both ends of the first clamping plate 2.

[0043] In the specific implementation process: When using the device, the user activates the telescopic cylinder 209, which drives the connecting block 206 to rise vertically. Simultaneously, the connecting block 206 pulls the ends of the two third rotating arms 205 vertically upwards. While one end of each third rotating arm 205 rotates, the other end pulls the rotating connection between the first rotating arm 203 and the second rotating arm 204. This causes the second rotating arm 204 to pull the first clamping plate 2 vertically, compressing the spring 210. At this point, the steel pipe is placed inside the first clamping plate 2 and the second clamping plate 208. The user then activates the telescopic cylinder 209 again, which drives the connecting block 206 to descend vertically, extending and retracting... As the cylinder 209 descends vertically, it drives the two third rotating arms 205 and the connecting block 206 to gradually rotate to a horizontal state. At this time, the third rotating arms 205 push the rotating connection of the first rotating arm 203 and the second rotating arm 204 until the first rotating arm 203 and the second rotating arm 204 are in the same vertical state. At this time, the first rotating arm 203 and the second rotating arm 204 are both in a vertical state with no component force in the tilt direction. At the same time, the two third rotating arms 205 are perpendicular to the first rotating arm 203 and the second rotating arm 204. The force between the two oppositely arranged third rotating arms 205 cancels out, thereby realizing the self-locking function of the device and increasing the stability of the steel pipe clamping.

[0044] Example 2:

[0045] Please see Figure 1 - Figure 4 This embodiment provides a hydraulic engineering pipeline lifting tool that facilitates limiting the middle and both ends. The specific idea is as follows:

[0046] The water conservancy project pipeline lifting tool includes a fixed plate 1. In addition, the water conservancy project pipeline lifting tool also includes a first clamping plate 2 and a second clamping plate 208 disposed below the fixed plate 1. The arc-shaped structure of the first clamping plate 2 and the second clamping plate 208 can firmly clamp the outside of the steel pipe to ensure the stability of the clamping of the steel pipe. It also includes a limiting plate 3 on one side of the first clamping plate 2. The limiting plate 3 can limit the end of the steel pipe to prevent it from lateral displacement.

[0047] In order to achieve the limiting function of the limiting plate 3, this embodiment provides a support member. The support member can limit both ends of the steel pipe and lift the middle part of the steel pipe at the same time. At the same time, the stability of the device is increased by dynamically adjusting the clamping force of the limiting plate 3 on the end of the steel pipe.

[0048] The support components of this embodiment include: a sliding fixing block 301 slidably connected to the outer sides of both ends of the fixing plate 1; a second rope 302 fixedly connected to one side of the sliding fixing block 301; one outer side of the limiting plate 3 connected to the outer side of the end of the second rope 302; a sliding plate 303 fixedly connected to one side of the second clamping plate 208; a sliding member 304 slidably connected to the inner side of the sliding plate 303; the upper surface of the sliding member 304 connected to the outer side of the bottom end of the limiting plate 3; a bottom block 305 fixedly connected to the lower surface of the sliding member 304; a support groove 306 is provided on the outer side of one end of the bottom block 305 for fitting the outer side of the pipe; a limiting rod 307 is fixedly connected to the outer side of one end of the bottom block 305; and the outer side of the support groove 306 is slidably connected to the inner side of the end of another bottom block 305.

[0049] In the specific implementation process: by connecting the sliding fixing block 301 to the outer fixing device, when the device is lifted, the sliding fixing block 301 will move towards the center. At the same time, the second rope 302 pulls the two limiting plates 3 towards the center to clamp them, thereby clamping both ends of the steel pipe. Meanwhile, the limiting plate 3 slides on the outside of the sliding plate 303 through the sliding member 304, driving the bottom block 305 at its bottom to move towards the center. At the same time, the vertical rod 207 on the outer side of the end of the third rotating arm 205 increases the stability of the sliding of the two third rotating arms 205. The end of the third rotating arm 205 can support the middle of the steel pipe.

[0050] Working principle:

[0051] Based on Example 1, the telescopic cylinder 209 is activated to drive a series of components in a coordinated manner, easily opening and closing the first clamping plate 2. This facilitates placing the steel pipe inside the first clamping plate 2 and the second clamping plate 208. The operation process is simple and easy to understand, reducing the difficulty of manual operation. When the telescopic cylinder 209 drives the connecting block 206 to descend, so that the first rotating arm 203 and the second rotating arm 204 are in the same vertical position, there is no tilting force. Moreover, the two third rotating arms 205 are perpendicular to the first rotating arm 203 and the second rotating arm 204, and the relative forces cancel each other out, achieving a self-locking function. This design makes the steel pipe clamped exceptionally firmly, effectively preventing the steel pipe from falling off even if it encounters shaking or external interference during hoisting, greatly improving the safety of hoisting operations. At the same time, the entire clamping process is completed through the precise coordination of the mechanical structure, and the force distribution is reasonable, which can ensure the clamping force while reducing damage to the surface of the steel pipe and protecting the integrity of the pipeline. In addition, the self-locking function does not require additional power to maintain, saving energy and reducing the risk of clamping failure due to power failure. This makes the hoisting and handling of pipelines in water conservancy projects more efficient and reliable, further enhancing the applicability of the device in actual construction scenarios.

[0052] Based on Embodiment 2, by connecting the sliding fixing block 301 to the outer fixing device, the sliding fixing block 301 moves towards the center when the lifting device is lifted. At the same time, the second rope 302 pulls the two limiting plates 3 towards the center to clamp them, achieving a stable fixation of both ends of the steel pipe. This synchronous clamping method ensures that the two ends of the steel pipe are subjected to balanced forces, preventing the pipe from tilting or falling off due to loosening at one end during lifting, and greatly improving the safety of lifting. Meanwhile, the limiting plate 3 slides on the outside of the sliding plate 303 through the sliding member 304, driving the bottom block 305 to move towards the center, further enhancing the clamping force on the steel pipe. The vertical rod 207 on the outer side of the end of the third rotating arm 205 improves the sliding stability. Together with the support of the end of the third rotating arm 205 for the middle of the steel pipe, a comprehensive fixing structure of "clamping at both ends + supporting in the middle" is formed, making the overall force on the steel pipe more uniform during lifting, effectively reducing pipe deformation or damage caused by excessive local force, and protecting the integrity of the pipe. This multi-part collaborative design not only makes the clamping more secure and reliable, adapting to the hoisting needs of steel pipes of different specifications, but also simplifies the operation process, achieving stable clamping without complicated manual adjustments. This improves the efficiency and safety of pipeline hoisting in water conservancy projects, and enhances the applicability and practicality of the device in actual construction.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
