[0003] When the oil pipe is under pressure, it will vibrate to a certain extent. However, the existing bearing device for the pipe cannot adjust its angle within a small floating range when the pipe vibrates slightly, causing the pipe to deviate from the bearing device and the pipe to be damaged.

[0094] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0095] See also Figures 1 to 14 As shown, a pipe bearing system for oil drilling includes a prefabricated cross bar 1, a docking piece 2, a docking block 3, a fixing structure 4, an anti-horizontal torsion structure 5 and an anti-vertical torsion structure 6;

[0096] The prefabricated crossbar 1 is connected to the outside;

[0097] The butt joint 2 is sleeved on the prefabricated cross bar 1, and a connecting cavity 21 is provided at the lower end of the butt joint 2;

[0098] A connecting column 31 is provided at the upper end of the docking block 3, and the connecting column 31 is inserted into the connecting cavity 21;

[0099] The fixing structure 4 includes an upper fixing member 41 and a lower fixing member 42;

[0100] The upper fixing member 41 is semicircular, with an opening facing downward, and a first hinge seat 411 is disposed at the upper end of the upper fixing member 41;

[0101] The lower fixing member 42 is semicircular, with an opening facing upward, and one end of the lower fixing member 42 is hinged to one end of the upper fixing member 41;

[0102] The anti-horizontal torsion structure 5 includes a first anti-horizontal torsion component 51 and a second anti-horizontal torsion component 52;

[0103] One end of the first anti-horizontal torsion component 51 is connected to one end of the docking block 3, and the other end of the first anti-horizontal torsion component 51 is connected to one side of the upper fixing member 41;

[0104] One end of the second anti-horizontal torsion component 52 is connected to the other end of the docking block 3, and the other end of the second anti-horizontal torsion component 52 is connected to the other side of the upper fixing member 41;

[0105] The anti-vertical torsion structure 6 comprises a first anti-vertical torsion component 61 and a second anti-vertical torsion component 62;

[0106] One end of the first anti-vertical torsion component 61 is connected to one side of the docking block 3, and the other end of the first anti-vertical torsion component 61 is connected to one end of the first hinge seat 411;

[0107] One end of the second anti-vertical torsion component 62 is connected to the other side of the docking block 3 , and the other end of the second anti-vertical torsion component 62 is connected to the other end of the first hinge seat 411 .

[0108] By setting a fixed structure 4, an anti-horizontal torsion structure 5 and an anti-vertical torsion structure 6, the anti-water torsion structure and the anti-vertical torsion structure 6 are connected to the fixed structure 4 and the prefabricated cross bar 1. The construction personnel use equipment to lift the pipe fittings, put the pipe fittings into the upper fixing member 41, and then close the lower fixing member 42 and the upper fixing member 41 into a closed circular ring to connect all the pipe fittings one by one. When the pipe fittings are pressed and shake, the first anti-horizontal torsion component 51 and the second anti-horizontal torsion component 52 cooperate to return the pipe fittings in the horizontal direction, and the first anti-vertical torsion component 61 and the second anti-vertical torsion component 62 cooperate to return the pipe fittings in the vertical direction, so that the axes of the pipe fittings are on the same horizontal straight line, thereby avoiding damage to the connection between the pipe fittings and the bearing device.

[0109] See also Figure 4 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 As shown, the first anti-horizontal torsion assembly 51 includes a first Y-shaped bracket 511, a second hinge seat 512 and a first shock absorber 513, and the second anti-horizontal torsion assembly 52 includes a second Y-shaped bracket 521, a third hinge seat 522 and a second shock absorber 523;

[0110] One end of the first Y-shaped bracket 511 is connected to one end of the upper fixing member 41;

[0111] The second hinge seat 512 is fixedly connected to one end of the docking block 3;

[0112] There are two first shock absorbers 513, one end of the two first shock absorbers 513 is hinged to the two ends of the second hinge seat 512 respectively, and the other end of the first shock absorber 513 is connected to the other end of the first Y-shaped bracket 511;

[0113] One end of the second Y-shaped bracket 521 is connected to the other end of the upper fixing member 41;

[0114] The third hinge seat 522 is fixedly connected to the other end of the docking block 3;

[0116] The first Y-shaped bracket 511, the second Y-shaped bracket 521, and the docking block 3 form a triangular stable state. The first Y-shaped bracket 511 and the second Y-shaped bracket 521 are respectively connected to the two ends of the upper fixing member 41, so that the fixing structure 4 is in a stable state. When the pipe swings in the horizontal direction, the first Y-shaped bracket 511, the second Y-shaped bracket 521 and the fixing structure 4 move synchronously, so that the fixing structure 4 and the pipe remain coaxial. At the same time, the first shock absorber 513 and the second shock absorber 523 absorb energy, so that the pipe gradually returns to work, thereby avoiding the pipe from being damaged in the horizontal direction.

[0117] See also Figures 8 to 10 As shown, the first anti-horizontal torsion assembly 51 further includes a first column 514, a first hinge sleeve 515 and a first spring telescopic rod 516, and the second anti-horizontal torsion assembly 52 further includes a second column 524, a second hinge sleeve 525 and a second spring telescopic rod 526;

[0121] One end of the second column 524 is fixedly connected to the middle of the third hinge seat 522;

[0122] The second hinge sleeve 525 is sleeved on the second column 524;

[0124] By setting the first column 514, the first hinge sleeve 515, the first spring telescopic rod 516, the second column 524, the second hinge sleeve 525 and the second spring telescopic rod 526, when deflection occurs between the first Y-shaped bracket 511 and the second Y-shaped bracket, the two first spring telescopic rods 516 on one side of the first Y-shaped bracket 511 are compressed and stretched respectively, and the two second spring telescopic rods 526 on one side of the second Y-shaped bracket 521 are compressed and stretched respectively, and the compressed first spring telescopic rod 516 and the compressed second spring telescopic rod 526 are reset to provide thrust, and the stretched first spring telescopic rod 516 and the stretched second spring telescopic rod 526 are reset to provide pulling force, so that the first Y-shaped bracket 511 and the second Y-shaped bracket 521 can be quickly reset.

[0125] See also Fig.11 As shown, a first connection hole 5141 is formed on one end of the first column 514 away from the end connected to the second hinge seat 512 , and a second connection hole 5151 is formed on the first hinge sleeve 515 .

[0126] By opening a first connecting hole 5141 on the first column 514 and a second connecting hole 5151 on the first articulated sleeve 515, the same operation is performed on the second column 524 and the second connecting sleeve. The first connecting hole 5141 is coaxial with the second connecting hole 5151, and bolts are inserted to fix the first column 514 and the first articulated sleeve 515, so that the first articulated sleeve 515 and the second articulated sleeve 525 will not fall off the first column 514.

[0127] See also Figure 4 , Figure 6 , Fig.12 , Fig.13 and Fig.14 As shown, the first anti-vertical torsion assembly 61 includes a first threaded column 611, a fourth hinge seat 612, a first sleeve 613, a second limiting ring 614 and a first pressure spring 615, and the second anti-vertical torsion assembly 62 includes a second threaded column 621, a fifth hinge seat 622, a second sleeve 623, a third limiting ring 624 and a second pressure spring 625;

[0128] One end of the first threaded column 611 is hinged to one end of the first hinge seat 411;

[0129] The fourth hinge seat 612 is fixedly connected to the middle part of one side of the docking block 3;

[0130] The first sliding sleeve 613 is sleeved on the first threaded column 611;

[0131] The second limiting ring 614 is sleeved on the first sliding sleeve 613, and one end of the second limiting ring 614 is hinged to the fourth hinge seat 612;

[0132] The first pressure spring 615 is sleeved on the first threaded column 611, one end of the first pressure spring 615 abuts against one end of the first threaded column 611, and the other end of the first pressure spring 615 abuts against the first sliding sleeve 613;

[0133] One end of the second threaded column 621 is hinged to the other end of the first hinge seat 411;

[0136] The third limiting ring 624 is sleeved on the second sliding sleeve 623, and one end of the third limiting ring 624 is hinged to the fifth hinge seat 622;

[0137] The second pressure spring 625 is sleeved on the second threaded column 621 , one end of the second pressure spring 625 abuts against one end of the second threaded column 621 , and the other end of the second pressure spring 625 abuts against the second sliding sleeve 623 .

[0138] By arranging the first threaded column 611, the fourth articulated seat 612, the first sliding sleeve 613, the second limiting ring 614, the first pressure spring 615, the second threaded column 621, the fifth articulated seat 622, the second sliding sleeve 623, the third limiting ring 624 and the second pressure spring 625, the first threaded column 611, the second threaded column 621 and the docking block 3 form a triangular stable structure. When the pipe fitting swings in the vertical direction, the first threaded column 611 moves obliquely upward under the restriction of the second limiting ring 614, the first pressure spring 615 is compressed, the second threaded column 621 moves obliquely downward under the restriction of the third limiting ring 624, the second pressure spring 625 is stretched, the compressed first pressure spring 615 is reset and the stretched second pressure spring 625 is reset, respectively providing thrust to the first threaded rod and pulling force to the second threaded rod. Under the reciprocating swing, the first pressure spring 615 and the second pressure spring 625 gradually provide the first threaded rod and the second threaded rod with forces of the same magnitude, so that the fixed structure 4 is in a balanced state in the vertical direction.

[0139] See also Figure 12 to Figure 14 As shown, the first anti-vertical torsion assembly 61 further includes a first hand-tightened nut 616, and the second anti-vertical torsion assembly 62 further includes a second hand-tightened nut 626;

[0140] The first hand-tightening nut 616 is connected to the first threaded column 611 , and one end of the first hand-tightening nut 616 is tightly pressed against the first sliding sleeve 613 ;

[0141] The second hand-tightening nut 626 is connected to the second threaded column 621 , and one end of the second hand-tightening nut 626 is tightly pressed against the second sliding sleeve 623 .

[0142] By setting the first hand nut 616 and the second hand nut 626, rotating the first hand nut 616 and the second hand nut 626, the first hand nut 616 and the second hand nut 626 move toward the first threaded column 611 and the second threaded column 621 respectively, and squeeze the second limit ring 614 and the third limit ring 624 downward respectively, the first pressure spring 615 and the second pressure spring 625 are compressed, so that the first pressure spring 615 and the second pressure spring 625 provide greater force, thereby limiting greater vibration of the pipe fitting.

[0143] See Figure Figure 4 , Figure 6 and Figure 7 As shown, the fixing structure 4 further includes a conflict locking assembly 43, which has two conflict locking assemblies 43, which are respectively arranged on both sides of one end of the upper fixing member 41, and the conflict locking assembly 43 includes a U-shaped frame 431, a locking shaft 432 and a pull ring 433;

[0144] The U-shaped frame 431 is fixedly connected to the upper fixing member 41;

[0145] One end of the locking shaft 432 is inserted into the upper fixing member 41, and the other end of the locking shaft 432 is arranged in the U-shaped frame 431;

[0146] The pull ring 433 is connected to one end of the locking shaft 432 close to the U-shaped frame 431 .

[0147] By setting the interference locking assembly 43, the staff hoist the pipe into the upper fixing member 41, rotate the lower fixing member 42, close the opening of the lower fixing member 42 and the opening of the upper fixing member 41, and then push the locking shafts 432 on both sides of the upper fixing member 41, and the two locking shafts 432 are inserted into the lower fixing member 42, so that the upper fixing member 41 and the lower fixing member 42 are fixedly connected, thereby fixing the pipe in the fixing structure 4.

[0148] See Figure Figure 6 and Figure 7 As shown, the interference locking assembly 43 further includes a first limiting ring 434 , which is sleeved on one end of the locking shaft 432 installed on the U-shaped frame 431 , and the first limiting ring 434 is disposed inside the U-shaped frame 431 .

[0149] By setting a first limiting ring 434, the first limiting ring 434 is fixedly connected to the locking shaft 432. When the locking shaft 432 is inserted into the lower fixing member 42, the first limiting ring 434 abuts against one side of the U-shaped frame 431, and the locking shaft 432 stops moving. At the same time, when the device is not in use, the first limiting ring 434 restricts the locking shaft 432 in the U-shaped frame 431, thereby preventing the locking shaft 432 from falling out of the U-shaped frame 431, thereby avoiding re-covering the locking shaft 432 when using the device.
