[0013] Compared with the existing technology, the iron roughneck spinner has the following beneficial effects:

[0014] First, the iron roughneck spinner of the present invention adopts a staggered roller structure, which has a wider pipe string range and improves the use range of the equipment without increasing the size of the entire spinner. In addition, the iron roughneck spinner adopts a four-motor parallel structure and adds a synchronous diverter valve block. The flow rate and pressure of each motor are equally distributed through several synchronous diverter valves in the valve block, thereby achieving synchronous drive of the four motors, with the same flow rate and pressure. At the same time, there is no pressure influence between the motors. In actual working conditions, deformation such as pipe string sag at the well site can easily cause one or more spinner rollers to slip, thereby reducing the pressure of all the spinner motors, resulting in low efficiency or even malfunction of the spinner.

The offset support mechanism provided in the present invention can provide support when the left roller assembly and the right roller assembly clamp the pipe column and perform high-speed tightening or loosening, so that the left roller assembly and the right roller assembly can perform stable screwing work on the pipe column, reduce the shaking effect during the screwing process, and effectively improve the screwing stability of the left roller assembly and the right roller assembly.

[0017] Fourth, the present invention is equipped with an extrusion spraying mechanism, a mobile cleaning mechanism, and a rotary vibration mechanism, which can promptly clean the left roller assembly and the right roller assembly after the work is completed, thereby removing dirt adhered to the surfaces of the left roller assembly and the right roller assembly during the screwing process, preventing the dirt from remaining on the surface and affecting the subsequent screwing work, thereby ensuring the stability of the left roller assembly and the right roller assembly, and thus ensuring the stability of the operation of the iron roughneck spinner.

[0031] According to the overall structure of the device, the roughneck spinner extends the clamping cylinder 1 of the spinner, and the front ends of the left and right arms 4 and 7 of the spinner are clamped, so that the left roller assembly 5 and the right roller assembly 6 simultaneously hold the pipe string, and then the four hydraulic motors are driven to drive the rollers 503 to rotate so that the pipe string is tightened / loosened at high speed. When the left and right roller assemblies 5 and 6 clamp the pipe string and perform high-speed tightening or loosening work, the offset support mechanism 10 can support the left and right roller assemblies 5 and 6, so that the left and right roller assemblies 5 and 6 can perform stable spinning work with the pipe string. After the left and right roller assemblies 5 and 6 finish working, they are cleaned in time by the extrusion spraying mechanism 11, the mobile cleaning mechanism 12 and the rotary vibration mechanism 13 to reduce the adhesion of dirt, so as to facilitate the subsequent spinning work and ensure the stability of the iron roughneck spinner.

The left roller bracket 502 is fixedly connected to the left arm 4 of the spinner via a pin, and the bearing assemblies 504 are installed at the top and bottom of the left roller bracket 502. The left roller bracket 502 is connected to the roller 503 via the all-axis roller shaft 505 and the key 506. The bearing assembly 504 at the top of the left roller bracket 502 is inserted into the spinner motor 501. The spinner base 3 is suspended on the spinner support frame of the iron roughneck. The left arm 4 of the spinner and the left roller assembly 5 form a scissor-shaped structure with the right arm 7 and the right roller assembly 6.

[0033] By setting the spinner to adopt a parallel structure of four motors and simultaneously driving the four motors in a synchronous shunt mode, the problem of roller 503 slipping caused by reasons such as pipe column depression is solved. At the same time, the spinner roller assembly is driven by a full-axis roller 503. Its structure is that the full-axis roller shaft 505 runs through the entire left roller bracket 502 and the right roller bracket. The full-axis roller shaft 505 passes through two sets of bearing assemblies 504. The entire structure has stronger bending resistance and increases the service life of the spinner.

The ends of the pair of fixed plates 1001 that are away from each other are rotatably connected to a pair of V-shaped connecting rods 1002 through two pairs of arc-shaped pieces, and the ends of the pair of side connecting plates 9 that are close to each other are fixedly connected to a pair of I-shaped rods 1003.

[0035] By setting the offset supporting mechanism 10, when the left roller assembly 5 and the right roller assembly 6 move to clamp the pipe column, the two pairs of V-shaped connecting rods 1002 deflect synchronously with the left roller assembly 5 and the right roller assembly 6, and pull the two pairs of movable blocks 1004 to move along the I-shaped rod 1003, while driving the two pairs of first rack plates 1006 to move synchronously. After the left roller assembly 5 and the right roller assembly 6 move to clamp the pipe column, they stop moving. At this time, a pair of electric telescopic rods 1007 pull the movable straight plates 1008 toward each other and drive the second rack plate 10010 to engage with the first rack plate 1006 through the connecting round rod 1009 to limit and fix them, so as to achieve resistance and support when the left roller assembly 5 and the right roller assembly 6 are tightened or loosened with the pipe column at high speed, reduce the shaking effect during the spinning process, and effectively improve the spinning stability of the left roller assembly 5 and the right roller assembly 6.

[0036] like Figure 1 、 Figure 6 and Figure 7 As shown, the squeezing spray mechanism 11 includes a pair of receiving frames 1101, the bottom ends of the pair of receiving frames 1101 are fixedly connected to the top ends of the pair of side connecting plates 9, and the ends of the pair of receiving frames 1101 away from each other are fixedly connected to a liquid storage frame 1102, and a plurality of evenly distributed sports spray bottle nozzles 1105 are embedded and connected between the liquid storage frame 1102 and the receiving frame 1101, and the ends of the pair of movable straight plates 1008 close to each other are fixedly connected to a push-pull rod 1104, and the end of the liquid storage frame 1102 close to the movable straight plate 1008 is opened. There is a circular hole, and the end of the push-pull rod 1104 away from the movable straight plate 1008 passes through the circular hole and is fixedly connected to a sealing extrusion plate 1103. The outer wall of the push-pull rod 1104 is in close contact with the inner wall of the circular hole, and the outer wall of the sealing extrusion plate 1103 is in close contact with the inner wall of the liquid storage frame 1102. A liquid injection port is opened at the top of the liquid storage frame 1102, and a sealing plug 1106 is provided on the top of the liquid injection port, and the outer wall of the sealing plug 1106 is in close contact with the inner wall of the liquid injection port. A pair of inner bottom ends of the storage frames 1101 are fixedly connected to a collection box 1107.

[0037] By setting up the extrusion spray mechanism 11, the sealing plug 1106 is removed and cleaning liquid can be added to the liquid storage frame 1102 through the liquid filling port. Then, when a pair of electric telescopic rods 1007 pull the movable straight plate 1008 toward each other, the pair of push-pull rods 1104 move synchronously with the movable straight plate 1008, driving the pair of sealed extrusion plates 1103 to move toward each other, and the cleaning liquid inside the liquid storage frame 1102 is squeezed through the sports spray bottle nozzle 1105 and sprayed toward the cleaning brush body 1208, soaking the cleaning brush body 1208 to facilitate subsequent cleaning and enhance the cleaning effect.

[0038] like Figure 1 、 Figure 7 and Figure 8As shown, the mobile cleaning mechanism 12 includes two pairs of sliding cylinders 1201, which are respectively fixedly connected to the outer walls of a pair of storage frames 1101, and a connecting frame 1202 is fixedly connected between the output ends of a pair of sliding cylinders 1201, the top of the connecting frame 1202 is fixedly connected to an L-shaped plate 1203, and one end of the L-shaped plate 1203 is fixedly connected to a lifting cylinder 1204, the bottom end of the lifting cylinder 1204 is fixedly connected to a motor 1205, and the bottom end of the motor 1205 is fixedly connected to a rectangular plate 1206, the bottom end of the rectangular plate 1206 is rotatably connected to a rotating rod 1207, and the top of the rotating rod 1207 is fixedly connected to the output end of the motor 1205, the outer wall of the rotating rod 1207 is fixedly connected to a cleaning brush body 1208, and the cleaning brush body 1208 is located in the storage frame 1101.

[0039] By moving the cleaning mechanism 12, a pair of slide cylinders 1201 on one side are operated to work, and the lifting cylinder 1204 and the cleaning brush body 1208 are driven to move to the central axis position between the left roller assembly 5 and the right roller assembly 6 through the connecting frame 1202 and the L-shaped plate 1203. Then the lifting cylinder 1204 drives the motor 1205 and the cleaning brush body 1208 to move downward until they come into contact with the roller 503. The left roller assembly 5 and the right roller assembly 6 drive the roller 503 to rotate. At the same time, the motor 1205 drives the rotating rod 1207 and the cleaning brush body 1208 to rotate in the opposite direction. The contact friction brushes and cleans the dirt on the surface of the roller 503, removes the dirt adhered to the surface of the left roller assembly 5 and the right roller assembly 6 during the spinning process, and prevents the dirt from staying on the surface and affecting the subsequent spinning work. The cleaning brush body 1208 on the other side cleans the left roller assembly 5 and the right roller assembly 6 after they continue to work. The alternating cleaning of a pair of cleaning brush bodies 1208 ensures the cleanliness of the left roller assembly 5 and the right roller assembly 6, reduces the interference with the spinning work, ensures the stability of the left roller assembly 5 and the right roller assembly 6, and thus ensures the stability of the work of the iron roughneck spinner.

[0040] like Figure 1 、 Figure 8 and Figure 9As shown, the rotating vibration mechanism 13 includes two pairs of connected rotating plates 1301, and the two pairs of connected rotating plates 1301 are respectively fixedly connected to the outer walls of a pair of rotating rods 1207, and the top ends of the two pairs of connected rotating plates 1301 are embedded with a cylinder 1302, and the inner wall of the cylinder 1302 is slidably connected with a T-shaped circular convex rod 1303, the inner bottom end of the cylinder 1302 and one end of the T-shaped circular convex rod 1303 are fixedly connected with a second spring 1304, and the inner top end of the cylinder 1302 is drilled with a through hole, the other end of the T-shaped circular convex rod 1303 passes through the through hole and contacts the bottom end of the rectangular plate 1206, the bottom end of the rectangular plate 1206 is fixedly connected with a plurality of evenly distributed semicircular protrusions 1305, and the T-shaped circular convex rod 1303 is located between the plurality of semicircular protrusions 1305.

[0041] Through the setting of the rotating vibration mechanism 13, a pair of connected rotating plates 1301 rotate synchronously with the rotating rod 1207, driving a pair of cylinders 1302 and T-shaped round protrusions 1303 to perform circular motion along the bottom end of the rectangular plate 1206, and repeatedly contacting and moving away from multiple semicircular protrusions 1305 on the motion path. Under the squeezing of the semicircular protrusions 1305 and the alternating action of the elasticity of the second spring 1304, the T-shaped round protrusions 1303 repeatedly contact and collide with the bottom end of the rectangular plate 1206, generating vibration, which is transmitted to the rotating rod 1207 and the cleaning brush body 1208. The vibration action is used to shake off the dirt attached to the cleaning brush body 1208 during the cleaning process, avoiding obstruction and interference to the cleaning of the cleaning brush body 1208, and effectively enhancing the cleaning effect of the cleaning brush body 1208 on the roller 503.

[0042] Working principle: The spinner clamping cylinder 1 extends to drive the front ends of the left and right arms 4 and 7 of the spinner to deflect and clamp, so that the left roller assembly 5 and the right roller assembly 6 can simultaneously hold the pipe column. At the same time, the two pairs of V-shaped connecting rods 1002 deflect synchronously with the left and right roller assemblies 5 and 6, and pull the two pairs of movable blocks 1004 and the first rack plate 1006 to move along the I-shaped rod 1003. After the left and right roller assemblies 5 and 6 move to clamp the pipe column, a pair of electric telescopic rods 1007 pull the movable straight plates 1008 toward each other and drive the second rack plate 10010 and the first rack plate 1006 through the connecting round rod 1009. At the same time, a pair of push-pull rods 1104 move synchronously with the movable straight plate 1008, driving a pair of sealing extrusion plates 1103 to move toward each other, squeezing the cleaning liquid inside the liquid storage frame 1102 to be sprayed to the cleaning brush body 1208 through the sports spray bottle nozzle 1105, soaking the cleaning brush body 1208, and then driving the four hydraulic motors to drive the roller 503 to rotate to tighten or loosen the pipe column at high speed. After the tightening or loosening work is completed, the left roller assembly 5 and the right roller assembly 6 are away from the pipe column, and the pair of sliding cylinders 1201 on one side of the operation work, driving the lifting cylinder through the connecting frame 1202 and the L-shaped plate 1203. 1204 and the cleaning brush body 1208 move to the central axis position between the left roller assembly 5 and the right roller assembly 6, and then the lifting cylinder 1204 drives the motor 1205 and the cleaning brush body 1208 to move downward until they contact the roller 503, and the left roller assembly 5 and the right roller assembly 6 drive the roller 503 to rotate. At the same time, the motor 1205 drives the rotating rod 1207 and the cleaning brush body 1208 to rotate in the opposite direction, and they rotate and rub against each other, and a pair of connecting rotating plates 1301 rotate synchronously with the rotating rod 1207, driving a pair of cylinders 1302 and T-shaped round protruding rods 1303 to perform circular motion along the bottom end of the rectangular plate 1206. , and contacts with multiple semicircular protrusions 1305 in turn on the movement path. After being squeezed by them, it moves toward the inside of the cylinder 1302 and separates from the bottom end of the rectangular plate 1206. After the T-shaped circular protrusion rod 1303 is away from the semicircular protrusion 1305 at this position, the T-shaped circular protrusion rod 1303 is reset upward under the elastic action of the second spring 1304, and contacts and collides with the bottom end of the rectangular plate 1206. This is repeated to generate vibration, which is transmitted to the rotating rod 1207 and the cleaning brush body 1208, shaking off the dirt attached to the cleaning brush body 1208 during the cleaning process, making it easier for the cleaning brush body 1208 to brush and clean the dirt on the left roller assembly 5 and the right roller assembly 6.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
