Description

Technical Field

[0001] This utility model relates to the field of geological pipeline installation technology, specifically to pipeline installation lifting equipment. Background Technology

[0002] During urban planning, it is necessary to install geological pipelines. During the installation process, it is easy to encounter situations where geological pipelines are installed in unfavorable geological conditions. Unfavorable geological conditions mainly include: soft clay, miscellaneous fill, eroded fill, expansive soil, red clay, peat soil, karst, collapsible loess, etc.

[0003] Under special geological conditions such as soft soil foundations, landslides, and karst caves, pipelines are highly susceptible to factors such as slope sliding and soil displacement during placement and installation, which can cause the placed pipelines to tilt. These adverse factors can lead to overall deformation and instability of the pipeline, seriously affecting the stability of the pipeline positioning, thus bringing many difficulties to the construction, delaying the construction progress, and even threatening the quality of the project.

[0004] To address the above issues, a pipeline installation lifting device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline installation lifting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The pipeline installation lifting equipment includes a lowering plate, a fixed plate, and a fixed frame. Two sets of positioning plates are fixedly connected to the top of the lowering plate. Two sets of baffles are rotatably connected to the bottom of the fixed frame. Two sets of rotating rods are rotatably connected to the side of the two sets of baffles that are close to each other. The same set of lifting plates is rotatably connected to the side of the two sets of rotating rods that are close to each other. The positioning plate is provided with an adjustment component for adjusting the up and down movement of the lifting plate.

[0008] The bottom of the descending plate is slidably connected to four sets of movable plates, and the bottom of each movable plate is fixedly connected to an arc-shaped plate. The descending plate is provided with a moving component for adjusting the four sets of arc-shaped plates to move closer to each other, and the fixed plate is provided with a driving component for driving the descending plate to slide.

[0009] In one alternative embodiment: the adjusting assembly includes a slide rod and a pressing plate, the bottom of the slide rod is fixedly connected to the top of the lifting plate, the bottom of the pressing plate is fixedly connected to the top of the slide rod, the slide rod is slidably connected to the fixed frame, a spring is sleeved on the slide rod, the spring is connected between the bottom of the pressing plate and the top of the fixed frame, and the top of the pressing plate overlaps with the bottom of the positioning plate.

[0010] In one alternative: the moving component includes a slider, which is fixedly connected to the top of the moving plate. The bottom of the descending plate has a groove for sliding with the slider. A bidirectional threaded rod is rotatably connected in the groove. The bidirectional threaded rod is threadedly connected to two sets of sliders. The two sets of threads on the bidirectional threaded rod corresponding to the sliders have opposite directions of rotation.

[0011] In one alternative: the drive assembly includes two sets of electro-hydraulic rods, which are mounted on a fixed plate. The power output piston rod of the electro-hydraulic rod is fixedly connected to the top of the descending plate. Guide blocks are fixedly connected to both sides of the positioning plate. The bottom of the fixed plate is fixedly connected to the top of the fixed frame through four sets of positioning posts. The positioning posts are provided with guide grooves for cooperating with the guide blocks to move up and down.

[0012] In one alternative: both the slider and the groove have T-shaped cross-sections.

[0013] In one alternative: the curved plate has a rubber layer on the side near the pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model incorporates an adjustment component, a baffle, a rotating rod, a lifting plate, a drive component, a lowering plate, and an arc-shaped plate. The drive component moves the lowering plate downwards, causing the arc-shaped plate to move the pipe downwards. The lowering plate moves the positioning plate, which in turn moves the adjustment component to adjust the lifting plate downwards. The two sets of rotating rods rotate due to the downward movement of the lifting plate, causing the baffle to rotate and become perpendicular to the fixed frame. This design reduces the risk of pipe tilting due to factors such as slope slippage and soil displacement during installation.

[0016] This invention, by setting a movable component, can drive an arc-shaped plate to clamp and fix the pipe, making it convenient to move and install the pipe. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] 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.

[0023] Please see Figures 1-3 In this embodiment, the pipeline installation lifting device includes a lowering plate 11, a fixing plate 28, and a fixing frame 26. Two sets of positioning plates 16 are fixedly connected to the top of the lowering plate 11, and two sets of baffles 27 are rotatably connected to the bottom of the fixing frame 26. Two sets of rotating rods 21 are rotatably connected to the side of the two sets of baffles 27 that are close to each other. The same set of lifting plates 22 is rotatably connected to the side of the two sets of rotating rods 21 that are close to each other. An adjustment component for adjusting the up and down movement of the lifting plate 22 is provided on the positioning plate 16.

[0024] The bottom of the descending plate 11 is slidably connected to four sets of movable plates 12, and the bottom of the movable plates 12 is fixedly connected to arc-shaped plates 13. The descending plate 11 is provided with a moving component for adjusting the four sets of arc-shaped plates 13 to move closer to each other in pairs. The fixed plate 28 is provided with a driving component for driving the descending plate 11 to slide.

[0025] The adjustment assembly includes a slide rod 23 and a pressing plate 25. The bottom of the slide rod 23 is fixedly connected to the top of the lifting plate 22, and the bottom of the pressing plate 25 is fixedly connected to the top of the slide rod 23. The slide rod 23 is slidably connected to the fixed frame 26. A spring 24 is sleeved on the slide rod 23. The spring 24 is connected between the bottom of the pressing plate 25 and the top of the fixed frame 26. The top of the pressing plate 25 overlaps with the bottom of the positioning plate 16. The positioning plate 16 presses the pressing plate 25. The pressing plate 25 drives the slide rod 23 to move downward and presses the spring 24. The slide rod 23 slides downward on the fixed frame 26 and drives the lifting plate 22 to move. As the lifting plate 22 moves downward, the two sets of rotating rods 21 rotate, causing the baffle 27 to rotate. This can reduce the effects of factors such as slope slippage and soil displacement, which could cause the placed pipe to tilt.

[0026] The moving component includes a slider 14, which is fixedly connected to the top of the moving plate 12. The bottom of the descending plate 11 has a groove for sliding with the slider 14. A bidirectional threaded rod 15 is rotatably connected in the groove. The bidirectional threaded rod 15 is threadedly connected to two sets of sliders 14. The two sets of threads on the bidirectional threaded rod 15 have opposite directions of rotation to the sliders 14. When the bidirectional threaded rod 15 is rotated, the two sets of sliders 14 move the moving plate 12 away from each other, so that the arc plate 13 releases its restriction on the pipe, allowing the pipe to be fixed and moved, facilitating installation.

[0027] The drive assembly includes two sets of electro-hydraulic rods 20, which are mounted on a fixed plate 28. The power output piston rods of the electro-hydraulic rods 20 are fixedly connected to the top of the descending plate 11. Guide blocks 17 are fixedly connected to both sides of the positioning plate 16. The bottom of the fixed plate 28 is fixedly connected to the top of the fixed frame 26 through four sets of positioning posts 19. The positioning posts 19 are provided with guide grooves 18 for cooperating with the guide blocks 17 to move up and down. When the electro-hydraulic rods 20 start working, they extend downwards, driving the descending plate 11 to move downwards. As the descending plate 11 moves, the guide blocks 17 slide downwards in the guide grooves 18, which can raise and lower the pipeline for easy installation.

[0028] Both the slider 14 and the slide groove have T-shaped cross sections. By setting the T-shaped slider 14 and slide groove, the movement of the moving plate 12 and the arc plate 13 can be supported.

[0029] The arc-shaped plate 13 has a rubber layer on the side near the pipe. By setting the rubber layer on the inner side of the arc-shaped plate 13, the pipe can be fitted and easily fixed.

[0030] The working principle of this utility model is as follows: The fixing plate 28 is installed on the movable frame. When installing the pipe, the fixing plate 28 is first moved downwards so that the baffle 27 is located in the trench where installation is required. The electric hydraulic rod 20 then starts working, extending downwards and driving the lowering plate 11 to move downwards. As the lowering plate 11 moves, it drives the guide block 17 to slide downwards within the guide groove 18. The positioning plate 16 presses against the pressing plate 25. The pressing plate 25 drives the sliding rod 23 downwards and presses against the spring 24. The sliding rod 23 moves downwards on the fixing frame 26. The sliding mechanism moves the lifting plate 22 downwards. As the lifting plate 22 moves downwards, the two sets of rotating rods 21 rotate, causing the baffle 27 to rotate. The pipe moves downwards and contacts the bottom of the ditch. The bidirectional threaded rod 15 rotates, and as the bidirectional threaded rod 15 rotates, the two sets of sliders 14 move the moving plate 12 away from each other, causing the arc plate 13 to loosen its restriction on the pipe, making it easier for workers to install the pipe. At the same time, the baffle 27 can reduce the effects of slope sliding, soil displacement, and other factors that may cause the placed pipe to tilt during the installation process.

[0031] 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 technical solution of the present utility model.
