Description

Technical Field

[0001] The utility model relates to a pipe burying device, in particular to a pipe burying device for water conservancy and hydropower projects, belonging to the technical field of water conservancy and hydropower projects. Background Technique

[0002] Water conservancy and hydropower projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits, and are also called water projects. Water is an indispensable precious resource for human production and life. However, its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the flow of water be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's life and production for water resources. When existing water conservancy and hydropower projects are under construction, pipelines are often buried, and a pipe burying device is required for the burial of pipelines.

[0003] A pipe burying device for water conservancy and hydropower projects disclosed in the Chinese Patent Application Publication Specification CN218935480U, by setting a structure that can lower the pipeline when burying the pipeline for water conservancy and hydropower projects, enables workers to suspend the pipeline above the trench through a rope body and a frame in some areas where machinery is inconvenient to operate, and then the rope body can be withdrawn for filling and burying the pipeline. The pipeline lowered by means of the rope body can contact the trench bottom more smoothly, avoiding the friction and collision damage of the pipeline when workers manually push the pipe body into the trench.

[0004] During the use of the above patent, although the two ends of the pipeline are lifted by setting suspension ropes, and at the same time, the rope body structure cooperates with the frame to suspend the pipeline above the trench and enter the trench, avoiding the problem of pipeline damage caused by directly pushing the pipeline into the trench by common pipe burying devices. However, during the descent of the rope body structure, there is a lack of an adjustment device for the rope fixing seat and the trench edge, and there is a risk of the pipe body colliding with the trench wall during the descent. At the same time, the above patent lacks the limit for the pipe body and only simply lifts the pipe body. When the installation positions of the suspension ropes at both ends are not symmetric along the center of the pipe body, and the two ends of the pipe body lack limit, there is a risk of the pipe body offsetting and falling. Content of the Utility Model

[0005] The utility model provides a pipe burying device for water conservancy and hydropower projects, which avoids the problem of the pipe body colliding with the trench during the descent process, and at the same time avoids the problem of the pipe body offsetting and falling due to lack of limit.

[0006] The present utility model is realized through the following technical solutions: A buried pipe device for water conservancy and hydropower projects, comprising two symmetrically arranged support devices. The support device includes a support frame. Below the support frame, there is a clamping device for clamping the pipeline. The clamping device includes a lifting plate.

[0009] On the left side surface of the left vertical plate, there is a forward and reverse motor installed. The output end of the forward and reverse motor is fixed to the rotating rod. The rotating rod can be driven to rotate through the output end of the forward and reverse motor.

[0010] On the bottom surface of the cross plate, there is a groove. Inside the inner wall of the groove, there is a sliding connection with a convex block. The convex block is fixed to its corresponding clamping plate. Inside the inner wall of the groove, there is a rotatable connection with a bidirectional threaded rod.

[0029] Please refer specifically to Figure 1 、 Figure 2 and Figure 3 , the support device 1 further includes two vertical plates 102 fixed to the upper surface of the support frame 101. Between the two vertical plates 102, a rotating rod 103 is rotatably connected. A cable 104 is installed on the outer surface of the rotating rod 103, and the other end of the cable 104 is connected to the lifting plate 201. By rotating the rotating rod 103, the cable 104 can be moved, and the lifting plate 201 can be pulled up and down through the cable 104. On the left side surface of the left vertical plate 102, a forward and reverse motor 105 is installed, and the output end of the forward and reverse motor 105 is fixed to the rotating rod 103. The rotating rod 103 can be driven to rotate through the output end of the forward and reverse motor 105.

[0030] Please refer specifically to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , a groove is opened on the bottom surface of the cross plate 202. A convex block is slidably connected to the inner wall of the groove, and the convex block is fixed to its corresponding clamping plate 203. A bidirectional threaded rod 208 is rotatably connected to the inner wall of the groove, and the bidirectional threaded rod 208 is threadedly connected to the convex block. A clamping motor 209 is installed on the side surface of the cross plate 202, and the output end of the clamping motor 209 is fixed to the bidirectional threaded rod 208. The bidirectional threaded rod 208 can be driven to rotate through the clamping motor 209, thereby driving the clamping plate 203 to move. A double-shaft motor 210 is installed on the upper surface of the lifting plate 201. Two auxiliary threaded rods 211 are installed at the output end of the double-shaft motor 210, and the auxiliary threaded rods 211 are threadedly connected to their corresponding threaded sleeves 205.

The support frame 101 can be driven to move through the supporting wheel 6.

[0032] Working principle: When in use, first start the clamping motor 209. The output end of the clamping motor 209 drives the bidirectional threaded rod 208 to rotate, and then drives the clamping plate 203 to move. The clamping plate 203 clamps the pipe body. Then start the forward and reverse motor 105. The output end of the forward and reverse motor 105 drives the rotating rod 103 to rotate, and then completes the release of the cable 104. The release of the cable 104 causes the lifting plate 201 to descend.

[0033] At the same time, start the electric push rod 4. When the clamping plate 203 clamps the side surface of the pipe body, the electric push rod 4 drives the clamping plate 3 to move. The end of the pipe body is clamped by the clamping plate 3 to realize the limitation of the pipe body, avoiding the problem that the pipe body deviates and falls due to lack of limitation.

[0034] When the lifting plate 201 descends to the inside of the groove, start the double-shaft motor 210. The double-shaft motor 210 drives the auxiliary threaded rod 211 to rotate, and then drives the threaded sleeve 205 to move. The auxiliary wheel 206 is driven by the threaded sleeve 205 to contact the side wall of the groove and provide lateral support for the lifting plate 201, avoiding the shaking of the lifting plate 201 during the lifting process, thus avoiding the problem that the pipe body will collide with the groove during the descending process. At the same time, start the auxiliary motor 207. The output end of the auxiliary motor 207 drives the auxiliary wheel 206 to rotate, and then drives the lifting plate 201 to continue to descend.

[0035] When the pipe body descends to the bottom of the groove, start the electric push rod 4. The electric push rod 4 drives the clamping plate 3 to move to release the limitation on the end of the pipe body. At the same time, the output end of the clamping motor 209 drives the bidirectional threaded rod 208 to rotate, and then drives the clamping plate 203 to move. The clamping plate 203 releases the clamping on the pipe body, and the pipe body falls into the groove, completing the movement of the pipe body.
