Description

Technical Field

[0001] The invention relates to the field of geological equipment accessories, and in particular to a double-blade drill rod mud scraping mechanism suitable for a trailer drilling rig platform. Background Art

[0002] Trailer-mounted drilling rigs play a key role in the extraction and drilling of resources like oil and natural gas, providing flexible mobility and convenient worksite support. However, a long-standing and pressing issue in drilling operations is the difficulty of cleaning the mud and dirt adhering to the drill pipe surface.

[0003] When the drill rod is finished drilling underground, a large amount of rock cuttings, mud and other impurities are brought out from the drilling environment, and these mud and dirt will adhere tightly to the surface of the drill rod. Traditional cleaning methods are often relatively crude, and it is common to use simple handheld tools to scrape and clean. This method is not only inefficient and consumes a lot of manpower costs, but also difficult to ensure the cleaning effect. It is easy to leave mud and dirt, which has many adverse effects on the subsequent storage, transportation and reuse of the drill rod, and even poses certain safety hazards. Trailer drilling platforms generally use drilling tools of different calibers, and existing scraping devices are difficult to adapt to the unique platform structure and drilling tool configuration of trailer drilling platforms. Therefore, in order to meet the needs of trailer drilling platforms for efficient, stable and accurate drill rod mud cleaning, there is an urgent need to develop a new drill rod scraper mechanism with good adaptability and efficient scraping performance to overcome the many shortcomings of existing technologies and improve the overall efficiency of drilling operations. Summary of the Invention

[0004] The present invention is intended to provide a double-blade drill pipe scraping mechanism suitable for a trailer drilling rig platform to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A double-blade drill rod scraper mechanism suitable for a trailer drilling rig platform includes a platform, a support frame, a drill rod, an upper leaf of a scraper, a lower leaf of a scraper and a rotating shaft pin. The support frame is arranged below the platform, and a cavity is formed between the two. The upper leaf of the scraper and the lower leaf of the scraper are arranged in the cavity. The rotating shaft pin hinges the upper leaf of the scraper and the lower leaf of the scraper and fixes them to the platform. The drill rod is vertically inserted into the platform, the support frame, the upper leaf of the scraper and the lower leaf of the scraper; and scraping rubber pads are provided in the upper leaf of the scraper and the lower leaf of the scraper.

[0007] Preferably, the upper leaf of the scraper blade and the lower leaf of the scraper blade are both composed of a fixed steel plate and the scraper rubber pad, forming a double-layer structure where the fixed steel plate sandwiches the scraper rubber pad; the fixed steel plate and the scraper rubber pad contained in the upper leaf of the scraper blade and the lower leaf of the scraper blade are pressed and fixed by a number of screws.

[0008] Preferably, the fixed steel plate body is a rectangular structure with a large fan-shaped hollow structure in the middle, and the centers of the large fan-shaped hollow structures of the upper and lower leaves of the scraper blade can completely coincide with each other.

[0009] Preferably, the fixed steel plate on the upper part of the upper blade of the scraper is the same as the fixed steel plate on the lower part of the lower blade of the scraper.

[0010] Preferably, the fixed steel plate at the lower part of the upper leaf of the scraper and the fixed steel plate at the upper part of the lower leaf of the scraper both include a square columnar handle extending outward, and the center line of the columnar structure is on the same line as the center of the large fan-shaped hollow structure.

[0011] Preferably, the upper surface of the fixed steel plate on the upper part of the scraper lower blade includes three support column structures.

[0012] Preferably, the scraper rubber pad is a rectangular structure with a semicircular hollow structure in the middle, and the semicircular hollow structure is radiated and hollowed out to one side along the upper and lower end points.

[0013] Preferably, the rotating shaft pin completely passes through the upper blade and the lower blade of the scraper, and is located at the front end of the upper blade and the lower blade of the scraper, and its center is in a straight line with the large fan-shaped hollow structure and the center line of the columnar handle.

[0014] Preferably, a square ring-mounted locking hoop is provided on the outer surface of the two columnar handles.

[0015] Preferably, two parallel columnar structures are provided below the lower leaf of the scraper and in parallel directions, completely covering the lower leaf of the scraper and the upper leaf of the scraper. The distance between the two columnar structures is greater than the diameter of the drill bit in the borehole, and both ends are vertically connected to the lower surface of the trailer platform by steel plates welded to form a support frame structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention proposes a double-blade drill rod scraper mechanism suitable for a trailer drilling rig platform, which is suitable for the trailer drilling rig platform and can achieve efficient mud scraping and improve the construction environment. The mechanism adopts an upper and lower double-blade overlapping structure, which effectively solves the problem that the trailer drilling rig platform lacks an adapted drill rod scraper structure. It can scrape off a large amount of mud in time during the drill rod lifting process to avoid mud splashing on the site, greatly improving the workers' harsh construction conditions, while reducing pollution to the land environment, and creating a good production environment for the drilling construction site.

[0018] 2. The present invention proposes a double-blade drill pipe scraper mechanism suitable for a trailer drilling rig platform. The scraper mechanism adopts scraper rubber pads inside the upper and lower leaves of the scraper and a unique fixed steel plate design, so that it can adapt to various types of drilling tools of different diameters used in trailer drilling platforms. There is no need to frequently replace scraper devices with different inner diameters, which overcomes the limitations of existing scraper devices and significantly improves the overall production efficiency of drilling operations.

[0019] 3. This invention proposes a dual-blade drill pipe scraper mechanism suitable for trailer drilling platforms. This mechanism features a replaceable rubber pad design, facilitating maintenance and reducing costs. When a normal-caliber drill tool is being pulled out of a borehole while connected to an oversized drill tool, the locking collar can be removed to separate the two blades, ensuring smooth passage of the oversized drill tool. The blades can then be closed to resume cleaning operations, flexibly addressing complex and diverse drilling conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0031] like Figure 1 As shown, a main body of a double-blade drill pipe scraper mechanism suitable for a trailer drilling rig platform includes a platform, a support frame, a drill pipe, an upper scraper blade, a lower scraper blade, and a rotating shaft pin. The support frame is arranged below the platform, and a cavity is formed between the support frame and the upper scraper blade and the lower scraper blade are arranged in the cavity. The rotating shaft pin hinges the upper scraper blade and the lower scraper blade and fixes them to the platform. The drill pipe is vertically inserted through the platform, the support frame, the upper scraper blade and the lower scraper blade.

[0032] The scraper upper blade 3, the scraper lower blade 4, the rotating shaft pin 5, and the scraper upper blade 3 and the scraper lower blade 4 are all provided with a scraper rubber pad 6, which ensures the adaptability of the scraper to the trailer drilling platform 1 and various drilling tools used therein.

[0033] The upper blade 3 of the scraper and the lower blade 4 of the scraper are both composed of a fixed steel plate 10 and the scraper rubber pad 6, forming a double-layer structure in which the fixed steel plate 10 sandwiches the scraper rubber pad 6, ensuring that the scraper rubber pad 6 has the flexibility to realize the scraping function while ensuring its structural strength.

[0034] The fixed steel plate 10 and the scraper rubber pad 6 included in the scraper upper leaf 3 and the scraper lower leaf 4 are penetrated and fixed by a plurality of screws 9, ensuring that the scraper rubber pad 6 can be replaced quickly and timely after being worn and damaged.

[0035] The main body of the fixed steel plate 10 is a rectangular structure with a large fan-shaped hollow structure in the middle, and the centers of the large fan-shaped hollow structures of the upper leaf 3 of the scraper and the lower leaf 4 of the scraper can completely coincide, ensuring that a sufficient area of the scraper rubber pad 6 is exposed in the fixed steel plate 10, ensuring the toughness of the scraper rubber pad 6, and ensuring that the hollow parts of the fixed steel plate 10 can be pieced together to form a complete circle.

[0036] The upper fixing steel plate 10 of the upper scraper blade 3 is the same as the lower fixing steel plate 10 of the lower scraper blade 4 , which reduces the difficulty in processing the fixing steel plate 10 .

[0037] The fixed steel plate 10 at the bottom of the upper scraper blade 3 and the fixed steel plate 10 at the top of the lower scraper blade 4 both include a square columnar handle 7 extending outward, and the center line of the columnar structure is on the same line as the center of the large fan-shaped hollow structure, ensuring that the overlap and separation of the upper scraper blade 3 and the lower scraper blade 4 can be performed at a position away from the trailer drilling rig platform 1, and when the upper scraper blade 3 and the lower scraper blade 4 overlap, the upper and lower columnar handles 7 can also be completely overlapped.

[0038] The upper surface of the fixed steel plate 10 on the upper part of the scraper lower blade 4 includes three support columns 8 structures, which ensures that the scraper lower blade 4 can support the lower surface of the trailer drilling rig platform 1 through the support columns 8 while cleaning the mud on the drill pipe 2, thereby reducing its own stress deformation and ensuring the structural strength of the scraper lower blade 4.

[0039] The scraper rubber pad 6 is a semicircular hollow structure in the middle of a rectangle, and the semicircular hollow structure radiates to one side along the upper and lower end points, ensuring that the scraper rubber pad 6 can overlap and splice into a complete circular hollow, and ensures that when a large-diameter drill tool exceeding the hollow diameter passes through the circular hollow, the scraper rubber pad 6 has sufficient elastic deformation ability to ensure that it is not easily damaged, and ensures that the cleaned mud can be discharged smoothly downward and will not accumulate on the scraper plate structure.

[0040] The rotating shaft pin 5 completely passes through the upper blade 3 of the scraper and the lower blade 4 of the scraper, and is located at the front end of the upper blade 3 of the scraper and the lower blade 4 of the scraper. The center of the circle is in a straight line with the large fan-shaped hollow structure and the center line of the columnar handle 7, realizing the working mode of the upper blade 3 of the scraper and the lower blade 4 of the scraper around the rotating shaft pin 5. When the normal-caliber drill tool is connected to the extra-large-caliber drill tool and is lifted out of the borehole, the upper blade 3 of the scraper and the lower blade 4 of the scraper can be separated around the rotating shaft pin 5 to ensure the smooth passage of the extra-large-caliber drill tool; when the extra-large-caliber drill tool passes through, the upper blade 3 of the scraper and the lower blade 4 of the scraper can be closed around the rotating shaft pin 5 to ensure that the scraper mechanism continues to complete the work of cleaning the mud from the drill rod 2.

[0041] A square ring-shaped locking collar 12 is sleeved on the outer surface of the two cylindrical handles 7. This ensures the scraper mechanism remains in place during normal operation. With the locking collar 12 installed, the passage of a drill rod 2 or large-diameter drilling tool will not cause the upper scraper blade 3 and lower scraper blade 4 to separate due to impact, thus causing the mechanism to fail. When an extra-large-diameter drilling tool passes, the locking collar 12 can be removed, allowing the upper scraper blade 3 and lower scraper blade 4 to separate smoothly.

[0042] Two parallel columnar structures are located below the lower scraper blade 4, completely covering the lower scraper blade 4 and the upper scraper blade 3. The distance between the two columns is greater than the diameter of the drill bit in the borehole. Their ends are vertically connected to the lower surface of the trailer platform 1 by steel plates welded together, forming a support frame 11. This ensures that the lower portion of the lower scraper blade 4 is effectively supported, preventing the scraper mechanism from falling off or being damaged in the event of an impact from above.

[0043] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
