Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a pipe lifting device for water conservancy projects. Background Art

[0002] A water conservancy project is a project built to eliminate water disasters and develop and utilize water resources. According to its service objects, it is divided into flood control projects, farmland water conservancy projects, hydropower projects, water supply and drainage projects, etc. A water conservancy project that can serve multiple purposes such as flood control, water supply, irrigation, and power generation at the same time is called a comprehensive utilization water conservancy project. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, channels, aqueducts, raft channels, and fishways to achieve their goals. During the construction of hydraulic structures, pipes often need to be lifted to direct a water source from one place to another.

[0003] After retrieval, for example, a pipe lifting device for a water conservancy project with the publication number CN216264356U fixes the position of the fixing plate by rotating and tightening the fixing rod, which is convenient for restricting the position of the pipe body, avoiding the phenomenon that the pipe body slides forward and falls. And by driving the pressing plate to flip forward through the protective plate that flips forward, the pressing plate is located above the pipe body. Driven by the pressing force of the compression spring, the pressing plate moves downward, so that the pressing plate presses the outer wall of the pipe body, increasing the friction force on the outer wall of the pipe body and avoiding the phenomenon that the pipe body shakes.

[0004] However, in actual use, for pipes with a smaller diameter, when they have to be inclined due to environmental factors such as terrain or topography or due to pipe laying plans, the outer wall of the pipe cannot be completely fixed only by the pressing force of the spring, and the pipe will still slide and fall. Content of the Utility Model

[0005] In view of the problems existing in the above-mentioned prior art, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a pipe lifting device for water conservancy projects, which solves the problem that the pipe is not firmly fixed when the above-mentioned patent lifts the pipe and the pipe will still slide and fall.

[0007] In order to achieve the above purpose, the present utility model provides the following technical solutions:

A vertical slideway is arranged on the outer wall of the vertical plate. A dovetail slider is slidably connected to the outside of the vertical slideway. A locking component is arranged between the vertical slideway and the dovetail slider. The locking component is used to fix the position of the dovetail slider on the vertical slideway. A fixing plate is welded on the outer wall of the dovetail slider. A lifting plate is arranged on the top of the fixing plate. A plurality of lower clamping blocks are arranged in an array on the top of the fixing plate. A plurality of upper clamping blocks are arranged in an array on the bottom of the lifting plate. The upper clamping blocks and the lower clamping blocks have the same structure and are arranged oppositely.

[0009] Preferably, a threaded rod is rotatably connected to the outer wall of the fixing plate through a bearing, and the top end of the threaded rod extends out of the top of the lifting plate. The threaded rod is in threaded connection with the lifting plate, and a knob is fixedly installed at the top end of the threaded rod.

[0010] Preferably, two limiting strips are symmetrically welded on the outer wall of the dovetail slider, and the lifting plate is located between the two limiting strips.

[0011] Preferably, flexible anti-slip pads are pasted on the clamping surfaces of the upper clamping blocks and the lower clamping blocks.

[0012] Furthermore, the locking component includes a plurality of lock holes opened on the outer wall of the vertical slideway, and the lock holes are arranged in two columns. A C-shaped block is welded on the outer wall of the dovetail slider. A plug rod is arranged inside the C-shaped block, and the plug rod is integrally in a "Y" shape.

[0013] Preferably, one end of the plug rod away from the lock hole movably penetrates through the wall of the C-shaped block. A handle is fixedly installed at one end of the plug rod away from the lock hole. A reset member is connected between the outer wall of the plug rod and the inner wall of the C-shaped block.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0015] 1. In the present utility model, a plurality of pipes are respectively placed on the lower clamping blocks, and then the lifting plate is lowered.

In the present utility model, when it is necessary to cancel the locking of the dovetail slider, pull the handle outward, drive the plug rod to disengage from the lock hole, and compress the reset member, so that the dovetail slider can slide freely on the vertical slideway. After adjusting to the required position, release the handle, and under the reset action of the reset member, the plug rod is inserted into any two adjacent lock holes again, and the operation is simple.

[0025] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0026] An embodiment of the present utility model discloses a pipeline lifting device for water conservancy projects.

[0027] The present utility model provides a Figures 1-5 As shown in the figure, a pipeline lifting device for water conservancy projects includes a lifting frame 1. A vertical plate 2 is integrally formed and connected to the top of the lifting frame 1. A vertical slideway 3 is provided on the outer wall of the vertical plate 2. A dovetail slider 4 is slidably connected to the outside of the vertical slideway 3. A locking assembly 5 is provided between the vertical slideway 3 and the dovetail slider 4. The locking assembly 5 is used to fix the position of the dovetail slider 4 on the vertical slideway 3. A fixed plate 6 is welded to the outer wall of the dovetail slider 4. A lifting plate 7 is provided on the top of the fixed plate 6. A plurality of lower clamping blocks 8 are arranged in an array on the top of the fixed plate 6. A plurality of upper clamping blocks 9 are arranged in an array on the bottom of the lifting plate 7. The upper clamping blocks 9 and the lower clamping blocks 8 have the same structure and are arranged oppositely.

[0028] Specifically, the lifting bracket 1 is composed of a chassis, two symmetrically arranged and cross - set connecting rods at the top of the chassis, a support plate at the top of the chassis, and two electric push rods. One set of oppositely arranged connecting rods and the support plate are fixedly installed, while the other set of oppositely arranged connecting rods and the support plate are slidably connected. By pushing the telescopic rod of the electric push rod to incline one set of oppositely arranged connecting rods, the overall support plate is inclined, facilitating the clamping and lifting of the pipeline.

[0029] Specifically, place multiple pipelines on the lower clamping block 8 respectively, then lower the lifting plate 7, and the upper clamping block 9 continuously approaches the lower clamping block 8 until the outer wall of the pipeline is firmly clamped, avoiding the displacement and slipping of the pipeline when being lifted or inclined, and improving the stability when lifting the pipeline.

[0030] To improve the practicality of this device, as Figure 3 shown, a threaded rod 10 is rotatably connected to the outer wall of the fixing plate 6 through a bearing, and the top end of the threaded rod 10 extends out of the top of the lifting plate 7. The threaded rod 10 is threadedly connected to the lifting plate 7, and a knob is fixedly installed at the top end of the threaded rod 10.

[0031] Specifically, by turning the knob to drive the threaded rod 10, the lifting plate 7 can be moved up or down, facilitating the adjustment to clamp pipelines with different diameters.

[0032] As Figure 3 shown, two limiting strips 11 are symmetrically welded to the outer wall of the dovetail slider 4, and the lifting plate 7 is located between the two limiting strips 11.

[0033] Specifically, by arranging the two limiting strips 11 on both sides of the lifting plate 7, when the lifting plate 7 moves up and down as the threaded rod 10 rotates, it can only move linearly and cannot deflect.

[0034] As Figure 1 shown, flexible anti - slip pads are pasted on the clamping surfaces of the upper clamping block 9 and the lower clamping block 8.

[0035] Specifically, the flexible anti - slip pads increase the friction force between the outer wall of the pipeline, further enhancing the stability when clamping and fixing the pipeline.

[0036] And to improve the functionality of this device, as Figure 4 、 Figure 5 shown, the locking component 5 includes a number of lock holes 501 opened on the outer wall of the vertical slideway 3, and the lock holes 501 are arranged in two columns. A C - shaped block 502 is welded to the outer wall of the dovetail slider 4, and an insertion rod 503 is arranged inside the C - shaped block 502, and the insertion rod 503 is overall in a "Y" shape.

[0037] Specifically, when it is necessary to adjust the height of the pipeline, the dovetail slider 4 is slid up and down, and the "Y"-shaped insertion rod 503 is inserted into any two adjacent lock holes 501, so that the dovetail slider 4 cannot move, thereby fixing the position of the dovetail slider 4 on the vertical slideway 3.

[0038] As Figure 4 shown, one end of the insertion rod 503 away from the lock hole 501 movably penetrates through the wall of the C-shaped block 502. A handle 504 is fixedly installed at the end of the insertion rod 503 away from the lock hole 501. A reset member 505 is connected between the outer wall of the insertion rod 503 and the inner wall of the C-shaped block 502.

[0039] Specifically, the reset member 505 can be selected as a spring according to the actual situation. When it is necessary to cancel the locking of the dovetail slider 4, the handle 504 is pulled outward to drive the insertion rod 503 out of the lock hole 501 and compress the reset member 505, so that the dovetail slider 4 can slide freely on the vertical slideway 3. After adjusting to the required position, the handle 504 is released. Under the reset action of the reset member 505, the insertion rod 503 is inserted into any two adjacent lock holes 501 again, and the operation is simple.

[0040] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
