Description

Technical Field

[0001] The utility model relates to a gas pipeline detection device, in particular to an excavation device for detecting a gas pipeline. Background Art

[0002] The complex underground gas pipeline network makes it easy for third-party construction workers to damage the pipelines, seriously impacting their safe operation. To prevent this, the location of the gas pipelines must be clearly defined before third-party construction begins. Although production management systems are currently in place, pipe location and burial depth may still vary due to issues such as original basic data, terrain changes, and interference with inspections. Therefore, careful manual excavation of test pits is necessary to locate the gas pipelines before third-party construction begins. A test pit approximately 0.6 meters deep (the typical depth of the top of a pipeline) requires approximately 1 square meter in size, and the pits must be larger as the pipelines are buried deeper. If the pipeline is not found, excavation must be repeated until it is unearthed, which is time-consuming and labor-intensive. Utility Model Content

[0003] In order to solve the above-mentioned problem of not being able to quickly confirm the buried position of the gas pipeline, the utility model provides an excavation device for detecting the gas pipeline. The specific technical solution is as follows:

[0005] Preferably, the top of the sleeve is further provided with a top row of holes communicating with the digging hole.

[0006] Furthermore, the excavation device also includes: an extension rod, which is arranged on the top of the rotating shaft.

[0007] Preferably, the bottom of the sleeve is further provided with an inserting cutting edge.

[0008] Furthermore, the excavation hole is provided with an insertion groove located above the insertion cutting edge.

[0013] Furthermore, the anti-blocking groove is a spiral groove, and two of them are symmetrically provided.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model provides an excavation device for detecting gas pipelines to drill holes through a sleeve and a digging drill. By drilling holes to detect gas pipelines, only a deep hole needs to be drilled, and there is no need to dig a test pit.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] By drilling holes with drill 2 and removing soil with sleeve 1, the excavation and breaking of the soil can be carried out safely, conveniently and efficiently without damaging the pipeline, and the location of the gas pipeline can be found, solving the problem of unclear location of the gas pipeline, difficult and time-consuming manual excavation during third-party construction.

[0027] like Figures 1 to 9As shown, an excavation device for detecting gas pipelines includes a sleeve 1 and a drill 2. The sleeve 1 is cylindrical and has an excavation hole 11 within it. At least one side hole 12 is provided on the side of the sleeve 1, communicating with the excavation hole 11. Two side holes 12 are symmetrically provided to facilitate processing, ensure strength, and efficiently remove soil. A rotating sleeve 13 is mounted on the top of the sleeve 1, above the excavation hole 11 and the side holes 12. The rotating sleeve 13 is provided with a rotation hole 16. The drill 2 includes a rotating shaft 21, a spiral blade 22, and a drill bit 23. Two retaining rings 24 are provided at the top of the rotating shaft 21. The top of the rotating shaft 21 is rotatably mounted within the rotation hole 16. The retaining rings 24 are movably mounted at both ends of the rotating sleeve 13. The retaining rings 24 limit the axial position of the rotating shaft 21, preventing it from moving up and down. The retaining rings 24, located at the top of the rotating shaft 21, are threadedly attached to the rotating shaft 21, facilitating assembly and disassembly of the rotating shaft 21. A drill bit 23 is mounted at the bottom of the rotating shaft 21. A spiral blade 22 is mounted on the rotating shaft 21 and connected to the drill bit 23. The spiral blade 22 extends from the side hole 12 to the drill bit 23 and is connected to the drill bit 23. The drill bit 23 includes a drill base 231 and a drill cutter 232. The drill base 231 is fixed to the bottom of the rotating shaft 21. At least two drill cutters 232 are provided. The drill cutters 232 are fixed to the drill base 231 in an annular array, and one of the drill cutters 232 is connected to the end of the spiral blade 22. The spiral blade 22 is movably positioned within the excavation hole 11, while the drill bit 23 is located at the bottom of the excavation hole 11. The drill bit 23 is used to loosen the soil and drill into the soil. The spiral blade 22 is used to transport the soil excavated by the drill bit 23 to the side hole 12, through which the soil is discharged.

[0028] When detecting the gas pipeline 3, first connect the gasoline engine or electric motor to the top of the rotating shaft 21, start the gasoline engine or electric motor, and the gasoline engine or electric motor drives the digging drill 2 to rotate in the sleeve 1, and then insert the sleeve 1 into the ground at a preset position. The drill bit 23 starts to drill the soil, and the soil is lifted upward by the spiral blade 22. When the soil is lifted to the side discharge hole 12, the soil is discharged from the side discharge hole 12. When the sleeve 1 contacts the gas pipeline 3, it cannot descend. At this time, the position of the gas pipeline 3 can be determined. If the depth of the sleeve 1 descending exceeds the burial depth of the gas pipeline 3, it means that there is no gas pipeline 3 here and construction can be carried out.

[0029] Since drilling is used to detect gas pipelines, only a deep hole needs to be drilled and there is no need to dig a test pit. This greatly reduces the amount of excavated soil and effectively solves the problem of unclear gas pipeline locations, difficult and time-consuming manual excavation during third-party construction. The specific location of the gas pipeline can be confirmed quickly and safely.

[0030] The excavation device for detecting gas pipelines can penetrate 3 cm in about 10 seconds. The time for digging a 60 cm exploration pit is reduced from 40 minutes for conventional excavation to about 4 minutes, which greatly shortens the actual time. There is no need for excavator operation, which reduces the space and floor area required for the operation. The construction is more convenient and simple, and the accurate location of the gas pipeline can be confirmed safely, conveniently and efficiently, which improves work efficiency and safety and ensures the smooth operation of the gas pipeline.

[0031] The excavation device for detecting gas pipelines reduces the cost and risk of mechanical excavation, lowers the probability of accidents, effectively avoids damage to gas pipelines, improves construction efficiency, and achieves a significant improvement in economic benefits.

[0032] To improve mud removal, top holes 15 are provided at the top of sleeve 1, communicating with excavation hole 11. These holes are positioned between rotating sleeve 13 and sleeve 1, connecting the two via connecting ribs 14. If side holes 12 are unable to drain mud in time, these holes can be removed through top holes 15, ensuring operational reliability.

[0033] In order to improve the scope of application and increase the depth of the drill hole, the excavation device also includes an extension rod, the bottom of the extension rod is detachably mounted on the top of the rotating shaft 21, and the top of the extension rod is connected to a gasoline engine or an electric motor. When drilling a deep hole, soil is mainly discharged through the top discharge hole 15.

[0034] In order to facilitate the insertion of the sleeve 1 into the soil, an insertion cutting edge 17 is further provided at the bottom of the sleeve 1. The insertion cutting edge 17 is blunt and will not damage the gas pipe, but can be easily inserted into the soil to reduce the resistance of drilling.

[0035] In order to further reduce the resistance of drilling, the excavation hole 11 is further provided with an insertion groove 18 located above the insertion edge 17. The insertion groove 18 makes the bottom thickness of the sleeve 1 thinner, thereby reducing the resistance of insertion into the soil and making drilling more labor-saving.

[0036] In order to reduce the friction between the rotating shaft 21 and the rotating hole 16 , a rotating oil groove 31 is provided in the rotating hole 16 , and lubricating oil or grease is provided in the rotating oil groove 31 .

[0037] To reduce the frequency of refueling and ensure reliable lubrication, the rotating oil grooves 31 are symmetrically arranged in two spiral grooves. These two symmetrically arranged spiral grooves evenly distribute the lubricating oil or grease throughout the rotating hole 16, thereby ensuring reliable lubrication, reducing friction, and reducing wear between the rotating shaft 21 and the rotating hole 16, thereby ensuring coaxiality. The use of the rotating shaft 21 and the rotating hole 16 simplifies the structure, improves environmental adaptability, reduces processing difficulty, and solves various problems associated with the use of bearings.

[0038] In order to facilitate refueling, the rotating sleeve 13 is further provided with a refueling hole communicated with the rotating oil groove 31 .

[0039] To prevent drill bit 23 from damaging the gas pipeline, a safety gap H is provided between drill bit 23 and the bottom of sleeve 1. When the bottom of sleeve 1 contacts the gas pipeline, a gap remains between drill bit 23 and the gas pipeline, preventing drill bit 23 from contacting the gas pipeline and effectively protecting the gas pipeline. Safety gap H can be set to at least 5 mm.

[0040] In order to prevent mud from getting stuck in the excavation hole 11 , an anti-blocking groove 32 is provided on the inner circumferential surface of the excavation hole 11 . The anti-blocking groove 32 cooperates with the spiral blade 22 to prevent mud from getting stuck on the spiral blade 22 .

[0041] In order to further improve the crushing effect, the anti-blocking groove 32 is a spiral groove, and two are symmetrically provided.

[0042] The excavation device for detecting gas pipelines is small in size, light in weight, easy to carry, simple to operate, and can be operated by one person, while ensuring the safety of the user and not damaging the buried gas pipeline.
