Technical Field
[0001] The utility model belongs to the technical field of gas pipeline maintenance equipment, and particularly relates to a pipeline buried valve opening device. Background Art
[0002] Pipeline valves are provided on both the main pipeline and the branch pipelines. The pipeline valves are usually arranged in underground gas wells and are closed by manhole covers. Professional gas workers are required to open the manhole covers for the maintenance and repair of gas pipelines and pipeline valves. The traditional way to open pipeline valves is usually to use a wrench and have workers enter the well to open it. However, the remaining natural gas in the pipeline may leak instantaneously during the opening process, causing danger. Moreover, the operation space in the pipeline well is narrow, making it difficult for workers to operate after entering. Some existing pipeline buried valve opening devices can be used to open above the gas well. However, due to the different models of valves, their diameters and structures are different. Therefore, multiple opening devices need to be carried to carry out continuous operations, which is cumbersome. The opening device cannot be adjusted, and the adaptability range is small.

The main shaft 1 is a cylindrical structure with an opening on one side. The fixing component is arranged at the closed end of the bottom of the main shaft 1. The fixing component cooperates with the pipeline valve and is used to clamp the pipeline valve. The pipeline valve is opened by rotating the main shaft 1 through the rotating rod 2. The rotating rod 2 is a detachable structure on the main shaft 1. A limiting part 4 is arranged at the opening end of the top of the main shaft 1. The rotating rod 2 can pass through above the limiting part 4 and be inserted into the main shaft 1 to pry the manhole cover above the pipeline valve. The rotating rod 2 can be horizontally inserted into the limiting part 4, thus becoming the lever arm of rotation to rotate the main shaft 1 and drive the fixing component to rotate. A fastener 43 and an adjusting part 5 are arranged on the limiting part 4. One end of the fastener 43 is threadedly connected to the limiting part 4 and is vertically arranged. The adjusting part 5 is arranged at the other end of the fastener 43 and is in plug-in fit connection with the fastener 43. The fastener 43 is used to fix the rotating rod 2. After the rotating rod 2 is inserted into the limiting part 4, by rotating the fastener 43 through the adjusting part 5, the fastener 43 can squeeze and fix the rotating rod 2 in the limiting part 4. The adjusting part 5 is of an L-shaped structure, with a threaded rod 51 arranged in the middle thereof. A threaded groove is arranged on the fastener 43. The threaded rod 51 of the adjusting part 5 can be inserted into the threaded groove to rotate the fastener 43. The length of the rotating rod 2 is greater than the length of the main shaft 1. One end of the rotating rod 2 is provided with a wedge-shaped prying part. When the rotating rod 2 is inserted into the main shaft 1, its prying part is located above the limiting part 4 on the main shaft 1. After the rotating rod 2 is fixed by the fastener 43, the manhole cover can be pried by the combined action of the main shaft 1 and the rotating rod 2. When the rotating rod 2 is horizontally inserted into the limiting part 4, the rotating rod 2 and the main shaft 1 form a T-shaped structure, and the rotating rod 2 acts as the lever arm to facilitate rotating the main shaft 1 to unscrew the pipeline valve.

[0027] On the basis of the above embodiment, this embodiment further defines the limiting part 4. The limiting part 4 is of a T-shaped structure and includes a horizontal through hole 41 and a vertical through hole 42. The horizontal through hole 41 and the vertical through hole 42 are communicated with each other and are perpendicularly arranged. The vertical through hole 42 is coaxially arranged with the opening end of the main shaft 1. The fastener 43 is arranged on the side of the limiting part 4 and is communicated with the horizontal through hole 41 and the vertical through hole 42. The rotating rod 2 can pass through the vertical through hole 42 of the limiting part 4 and then be inserted into the main shaft 1, or the rotating rod 2 can pass through the horizontal through hole 41 of the limiting part 4 and then be perpendicular to the main shaft 1. After the rotating rod 2 is inserted into the vertical through hole 42 or the horizontal through hole 41, the end of the fastener 43 is perpendicular to the side surface of the rotating rod 2. Rotate the fastener 43 clockwise to make it approach the rotating rod 2 and press and fix the rotating rod 2 in the limiting part 4. Other parts of this embodiment are the same as those of the above embodiment and will not be elaborated here.

A relief groove 31 is provided at the lower end of the fixing head 3. The four limiting members 32 are arranged on the fixing head 3 and are perpendicular to the surface of the fixing head 3. The included angle between the four limiting members 32 is 90°. The four limiting members 32 are all threadedly connected to the fixing head 3. One end of the limiting member 32 can enter the relief groove 31 to abut against the pipeline valve. Rotating the limiting member 32 can adjust the insertion depth of the limiting member 32 in the relief groove 31. A polygonal groove is provided at the end of the limiting member 32 outside the fixing head 3. Both ends of the adjusting member 5 have a polygonal cross-section and are matched with the polygonal groove.
