After being processed into steel pipe, its bending resistance is significantly improved, and it can exert excellent load-bearing characteristics in geological environments with strong bearing layers.

[0003] During the implementation of this application, it was found that the technology has the following problems: the existing pipe strings mostly need to be manually installed during the assembly process, and the staff are required to support the position of the pipe strings during the installation process, which makes the subsequent staff spend more labor and time when splicing two sets of pipe strings.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A scratch-resistant pipe clamping and screwing tool includes a positioning mechanism, which is installed and positioned on the outer surface of a group of pipes. Two groups of fixing plates are installed on the front of the positioning mechanism.

[0027] like Figure 1 、 Figure 2 and Figure 4 As shown, the positioning mechanism 1 includes a fixed ring 101, a threaded hole is provided on the outer surface of the fixed ring 101, a bolt 102 is connected to the inner thread of the fixed ring 101, an arc-shaped limiting plate 104 is installed on the end of the bolt 102 close to the pipe column, and the side of the arc-shaped limiting plate 104 away from the bolt 102 is attached to the outer surface of the pipe column, a through hole is provided on the outer surface of the fixed ring 101, a positioning rod 103 is slidably connected to the through hole of the fixed ring 101, and the end of the positioning rod 103 close to the pipe column is installed on the side of the arc-shaped limiting plate 104 away from the pipe column;

[0028] The screwing mechanism 3 includes a fixing ring 1 301, which is installed on the side of the two groups of fixing plates 2 away from the positioning mechanism 1, and the side of the two groups of fixing plates 2 away from the fixing ring 1 301 is installed on the side of the fixing ring 101 close to the fixing ring 1 301. An annular groove is provided on the side of the fixing ring 1 301 away from the fixing ring 101, and an external thread is provided on the inner wall of the annular groove of the fixing ring 1 301. The external thread of the fixing ring 1 301 is connected to the fixing ring 3 302, and grooves are provided on the upper and lower sides of the outer surface of the fixing ring 302. Connecting sleeves 303 are installed inside the two groups of grooves of the fixing ring 302, and electric telescopic rods 304 are installed on the inner walls of the opposite sides of the two groups of connecting sleeves 303. The output ends of the two groups of electric telescopic rods 304 are installed with arc-shaped positioning blocks 305;

[0029] Specifically, by rotating multiple sets of bolts 102, multiple sets of arc-shaped limit plates 104 are pushed to move, and the inner walls of the multiple sets of arc-shaped limit plates 104 are abutted against the outer surfaces of a group of pipe strings, so that the device is subsequently positioned and installed at the outer ends of a group of pipe strings during use, so that subsequent staff do not need to support the tool when screwing the screwing mechanism 3 to install another group of pipe strings, thereby reducing the labor consumed by subsequent staff in operating the device.

[0030] When the cam 305 is in the closed position, the cam 306 is in the closed position, and the cam 307 is in the closed position, so that the cam 307 is in the closed position, and the cam 308 is in the closed position, so that the cam 308 is in the closed position, and the cam 309 is in the closed position, so that the cam 309 is in the closed position, and the cam 309 is in the closed position, so that the cam 309 is in the closed position, so that the cam 309 is in the closed position,

[0031] like Figure 1 and Figure 2 As shown, the outer surfaces of the two groups of connecting sleeves 303 are sleeved with rubber rings 4, and the adjacent sides of the two groups of rubber rings 4 are respectively in contact with the upper and lower sides of the fixed ring three 302; specifically, the positions of the two groups of rubber rings 4 are set on the outer surfaces of the connecting sleeves 303, so that the hands of subsequent staff members come into contact with the two groups of rubber rings 4 when pushing the two groups of connecting sleeves 303 to drive the fixed ring three 302 to rotate, thereby improving the comfort of subsequent staff members when pushing the two groups of connecting sleeves 303.

[0032] like Figure 4 As shown, rubber pads 7 are provided on the adjacent sides of the two groups of arc-shaped positioning blocks 305; specifically, the positions of the two groups of rubber pads 7 are set between the contact surfaces of the two groups of arc-shaped positioning blocks 305 and the pipe column, so that the rubber pads 7 shield and protect the contact surfaces between the arc-shaped positioning blocks 305 and the pipe column, thereby minimizing the arc-shaped positioning blocks 305 from leaving scratches on the outer surface of the pipe column during the subsequent screwing mechanism 3 screwing the pipe column, thereby improving the service life of the pipe column.

[0033] like Figures 1 to 3 As shown, the support mechanism 5 includes a connecting plate 501, which is installed between the adjacent side of the fixed ring 301 and the fixed ring 101. A fixing sleeve 502 is provided on the lower surface of the connecting plate 501, and a hydraulic cylinder 503 is installed on the top of the inner wall of the fixing sleeve 502. A support plate 504 is installed on the output end of the hydraulic cylinder 503; specifically, when two groups of adjacent pipe strings are spliced ​​together, the hydraulic cylinder 503 is started to push the support plate 504 to move and the lower surface of the support plate 504 is abutted against the ground, so that the support mechanism 5 supports the connection between the two groups of pipe strings, thereby minimizing the subsequent deviation of the connection between the two groups of pipe strings and causing the entire device to bend, thereby improving the service life of the device.

[0034] like Figure 2 and Figure 3 As shown, two groups of through holes are opened on the upper surface of the connecting plate 501, and the two groups of through holes of the connecting plate 501 are slidably connected to the limiting rods 6, and the two groups of limiting rods 6 are installed on the upper surface of the support plate 504; specifically, the two groups of limiting rods 6 are slidably connected to the two groups of through holes of the connecting plate 501, and then the two groups of limiting rods 6 are installed on the upper surface of the support plate 504, so that the subsequent two groups of limiting rods 6 limit the moving path of the support plate 504 at the lower end of the connecting plate 501, thereby avoiding the subsequent position of the support plate 504 from being offset during use, which causes the hydraulic cylinder 503 to bend, thereby improving the service life of the support mechanism 5.

[0035] In summary: by rotating multiple sets of bolts 102, multiple sets of arc-shaped limit plates 104 are pushed to move, and the inner walls of multiple sets of arc-shaped limit plates 104 are abutted against the outer surface of a group of pipe strings, so that the device is subsequently positioned and installed at the outer end of a group of pipe strings during use, so that subsequent staff do not need to support the tool when screwing the screwing mechanism 3 to install another group of pipe strings; by starting two sets of electric telescopic rods 304, the two sets of arc-shaped positioning blocks 305 are pushed to move, so that the inner walls of the two sets of arc-shaped positioning blocks 305 are abutted against the outer surface of the other set of pipe walls, and then by pushing the two sets of connecting sleeves 303, the two sets of arc-shaped positioning blocks 305 are driven to clamp the other group of pipe strings and screw them into the inner pipe strings of the positioning mechanism 1, so that the screwing mechanism 3 replaces manual screwing to assemble the two groups of pipe strings.

[0036] At the same time, the positioning mechanism 1 and the screwing mechanism 3 are respectively installed at the outer ends of the two groups of adjacent pipe strings, so that the positioning mechanism 1 and the screwing mechanism 3 limit and support the moving position of the connection between the two groups of pipe strings, thereby trying to avoid the subsequent bending of the connection between the positioning mechanism 1 and the screwing mechanism 3, which may cause damage to the two groups of pipe strings; by starting the hydraulic cylinder 503 to push the support plate 504 to move, the lower surface of the support plate 504 is abutted against the ground, so that the support mechanism 5 supports the connection between the two groups of pipe strings, thereby trying to avoid the subsequent deviation of the connection between the two groups of pipe strings, which may cause the entire device to bend.
