Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline devices, and in particular relates to a pipe embedding device for hydropower engineering. Background Art

[0002] Water conservancy and hydropower projects are projects built to eliminate water disasters and develop and utilize water resources. According to their service objects, they are divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects and sea reclamation projects. Water conservancy projects that can serve multiple goals such as flood control, water supply, irrigation and power generation are called comprehensive utilization water conservancy projects.

[0003] At present, when burying pipes in water conservancy and hydropower projects, they are all transported manually, but there is generally a disadvantage of low work efficiency. When burying pipes, it is mainly through manual transportation of pipes to designated places by workers, and then the pipe burying work is carried out. When the number of pipes is too large, the workers are required to carry out multiple transportation work, which will greatly reduce the efficiency of pipe burying and the work intensity of the workers.

[0004] The Chinese patent document with the publication number CN221246271U discloses a pipe burying device for hydropower engineering, which belongs to the technical field of hydropower engineering. The pipe burying device for hydropower engineering includes a transport mechanism, which includes a vehicle body, and adjustment parts are symmetrically arranged on both sides of the vehicle body. A pipe burying device is arranged inside the vehicle body, and the pipe burying device is symmetrically arranged at both ends of the vehicle body. The adjustment parts are used to adjust the length of the vehicle body and are applicable to pipes of different lengths. The pipe burying device cooperates with the vehicle body to transport and discharge the pipes one by one. The hydraulic cylinder is turned on to push the lower guide plate upward to push the pipe to one side of the auxiliary block and fall. At this time, the lower limit plate is lowered to prevent the pipe from falling and the upper limit plate is raised to make the pipe fall and move to one side of the lower limit plate, so that when encountering a slope, the pipe will not run out and discharge multiple pipes. The internal pipes are discharged one by one, which reduces the workload of the staff and improves the efficiency of pipe burying of the equipment. The device structure in the document is complex.

By placing the pipeline to be buried on the surface of the conveyor belt above the fourth driven shaft and the transmission shaft, each pipeline corresponds to a shelf frame and is placed in close contact with it. The transmission shaft is driven to rotate by the driving assembly, and then the conveyor belt is driven to rotate. During the process, the shelf frame with the pipeline in close contact with it will gradually move toward the front end of the base and tilt downward until the pipeline to be buried moves to the third driven shaft. The shelf frame at the position of the third driven shaft maintains a horizontal state, and as the conveyor belt continues to rotate, the shelf frame at the position of the third driven shaft continues to tilt and gradually loses support for the pipeline to be buried. When the angle of the shelf frame is completely inverted, the pipeline to be buried will also lose the support of the shelf frame and be placed in the position to be buried, thereby completing the laying of the pipeline without manual handling, effectively reducing labor intensity, improving pipe burying efficiency, reducing costs, and having a simple structure and a high degree of automation.
