Description

Technical Field

[0001] The invention relates to the technical field of derrick support rod surface cleaning, in particular to derrick support rod surface treatment equipment for petroleum drilling equipment. Background Art

[0002] The derrick support rods used in oil drilling equipment are important components of the derrick structure. They are made of high-strength steel and their main function is to enhance the overall stability and rigidity of the derrick, ensuring that the derrick can maintain its structural integrity and safety when bearing various complex loads during drilling operations. The derrick support rods have various layout forms and connection methods according to different derrick types and design requirements. They can be divided into diagonal support rods, horizontal support rods, etc. Figure 15 The existing support rod body 01 shown in the figure has a rectangular cross section and its two ends are fixedly connected to the derrick body.

[0003] The derrick operating environment is harsh, and the surface of the strut body 01 is prone to various impurities, such as oil and dust from the drilling process and corrosive particles from industrial exhaust. Long-term accumulation of these impurities can accelerate metal corrosion on the strut body 01, reducing structural strength and endangering the safety of the derrick. Oil and dust can also affect the adhesion of the strut body 01 coating, rendering the protective layer ineffective. Regular cleaning of the strut body 01 surface can promptly remove impurities, slow the corrosion process, ensure the integrity of the coating, and safeguard the structural stability of the derrick and strut body 01.

[0004] Derrick struts are typically installed at high altitudes, and traditional cleaning methods rely primarily on manual labor. Due to the complex structure and cramped conditions of the derrick, cleaning personnel are vulnerable to collisions, crushing, and falls as they climb and maneuver through the complex structure. This makes cleaning difficult and reduces the installation efficiency. Furthermore, manual cleaning effort and methods are difficult to standardize, leaving blind spots and significantly reducing cleaning effectiveness. This inefficiency can seriously impact the normal progress of oil drilling operations. All things considered, manual cleaning has numerous drawbacks. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects.

[0020] The equipment provided by the present invention can be matched and installed on the support pole body, and the high-temperature steam generated by the high-pressure steam cleaning machine installed on the ground is transmitted to the high-pressure steam nozzle over a long distance by a pipeline system, so as to perform high-temperature steam flushing and cleaning treatment on the surface of the support pole body.

The cleaning operation is performed along the serrated trajectory to ensure that the cleaning ranges of the high-pressure steam nozzle on the two adjacent transverse paths overlap, thereby ensuring that the cleaning surface sufficiently covers the surface of the support rod body, avoiding the existence of cleaning dead corners, and effectively improving the cleaning effect.

[0022] The present invention arranges the high-pressure steam nozzle perpendicular to the surface to be cleaned, so that the high-temperature steam ejected from the high-pressure steam nozzle acts on the target area in a concentrated manner, reducing energy loss caused by diffusion to the surrounding area, and then generating a greater impact directly acting on the surface of the stain, which helps to break the adhesion between the stain and the cleaning surface and improve the cleaning effect on stubborn stains.

[0023] The present invention arranges the sleeve frame seat and the annular frame in a split type. During disassembly and assembly, the sleeve frame seat and the annular frame can be disconnected to form a gap for the support rod body to pass through. Even when both ends of the support rod body are supported and connected to the derrick, the device can be normally disassembled and assembled, and has strong adaptability. In addition, through the corresponding layout of the arc segment A fixed to the U-shaped frame and the arc segment B fixed to the plate frame, the arc segment A and the arc segment B can be adaptively and synchronously assembled and disassembled when the U-shaped frame and the plate frame are assembled and disassembled, making the overall disassembly and assembly steps simple and quick.

[0024] The present invention provides a self-clamping locking mechanism on the plate frame. When the first driving mechanism is assembled in place, the wedge block is used to push the arc-shaped extrusion head to prompt the clamping rod to be inserted into the clamping hole, thereby realizing the assembly of the U-shaped frame and the plate frame, and the assembly of the arc segment A and the arc segment B. When the first driving mechanism is retracted and adjusted, the elastic reset of the reset spring is used to drive the clamping rod to disengage from the clamping hole, thereby realizing the disassembly of the U-shaped frame and the plate frame, and the separation of the arc segment A and the arc segment B, realizing a linkage disassembly and assembly mechanism, reducing the disassembly and assembly operation steps and time, and effectively improving the overall disassembly and assembly efficiency.

[0050] See also Figures 1-14 The present invention provides a surface treatment device for a derrick support rod used in oil drilling equipment. The embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention.

[0051] This processing equipment includes a sleeve seat 1 that can be matched and sleeved on the support rod body 01, an annular frame 2 installed on the outside of the sleeve seat 1, a second driving mechanism 4 that is sleeved on the annular frame 2 and can be rotated and adjusted around the support rod body 01, and a high-pressure steam nozzle 6 installed on the side of the second driving mechanism 4 through a movable frame group module 5. A first driving mechanism 3 is provided on the sleeve seat 1. The first driving mechanism 3 is used to drive the sleeve seat 1 to move along the length direction of the support rod body 01. The second driving mechanism 4 is used to drive the high-pressure steam nozzle 6 to rotate and adjust around the support rod body 01 to realize the switching of the cleaning surface so as to clean the four sides of the support rod body 01 respectively. The movable frame group module 5 can drive the high-pressure steam nozzle 6 to be adjusted horizontally in a direction perpendicular to the length direction of the support rod body 01.

[0052] The high-pressure steam nozzle 6 is connected to the high-pressure steam cleaning machine through the pipeline system 8, wherein the high-pressure steam cleaning machine adopts the existing technology, and the specific structure and working principle are no longer described in detail. The high-pressure steam cleaning machine is placed on the ground. Under the action of its internal high-pressure pump, the pipeline system 8 is used to transport the high-pressure steam to the high-pressure steam nozzle 6 for long-distance flushing of the body. High-pressure steam is ejected from the high-pressure steam nozzle 6. Since the steam has a high temperature and pressure, when it is sprayed onto the surface of the support rod body 01, it will produce a strong impact force and thermal effect. The high temperature softens and decomposes impurities such as oil stains, reducing their adhesion to the surface of the object. At the same time, the impact force of the high-pressure steam can wash away dust, corrosive particles and softened stains, thereby achieving the purpose of cleaning the outer surface of the support rod body 01.

[0053] The first driving mechanism 3 drives the sleeve frame 1 to move along the length direction of the support rod body 01, and the mobile frame module 5 drives the high-pressure steam nozzle 6 to adjust horizontally to realize the biaxial mobile cleaning operation of the high-pressure steam nozzle 6. When the high-pressure steam nozzle 6 is moving to clean the surface of the support rod body 01, Figure 13 As shown, the cleaning track is a curved reciprocating sawtooth track, which is composed of a transverse path 02 and a feed path along the length direction of the support rod body 01.

[0054] Since the high pressure steam nozzle 6 sprays steam to clean the area which is approximately circular, Figure 14As shown, the spraying range of the high-pressure steam nozzle 6 on one of the transverse paths 02 is defined as the cleaning area A03, and the spraying range of the high-pressure steam nozzle 6 on the adjacent transverse path 02 is defined as the cleaning area B04. There is an overlapping area between the cleaning area A03 and the cleaning area B04. At the same time, the span of the transverse path 02 is greater than the width of the side surface on any side of the support rod body 01, ensuring that the span of the transverse movement of the high-pressure steam nozzle 6 is sufficient to cover the width of the support rod body 01. When cleaning the surface on any side of the support rod body 01, it is ensured that the operating range of the high-pressure steam nozzle 6 is sufficient to cover the surface of the support rod body 01.

[0055] Among them, when the high-pressure steam nozzle 6 is aimed at the four side surfaces of the support rod body 01 for cleaning, the high-pressure steam nozzle 6 is perpendicular to the corresponding side surfaces of the sleeve frame seat 1, so that the high-temperature steam sprayed by the high-pressure steam nozzle 6 is concentrated on the target area, reducing the energy loss caused by diffusion to the surrounding area, and then generating a greater impact directly acting on the surface of the stain, which helps to break the adhesion between the stain and the cleaning surface and improve the cleaning effect of stubborn stains.

[0056] See also Figure 2 、 Figure 3 and Figure 10 The sleeve frame seat 1 is composed of a U-shaped frame 11 and a plate frame 12, and the annular frame 2 is composed of an arc segment A21 and an arc segment B22. The arc segment A21 is fixed on the U-shaped frame 11, and the arc segment B22 is fixed on the plate frame 12 through a fixed bracket 101. When the U-shaped frame 11 and the plate frame 12 are assembled into the sleeve frame seat 1, the arc segment A21 and the arc segment B22 are adaptively paired and assembled into the annular frame 2.

[0057] The sleeve frame seat 1 and the annular frame 2 are both set to be split. When disassembling and assembling, the sleeve frame seat 1 and the annular frame 2 can be disconnected to form a gap for the support rod body 01 to pass through. Therefore, even when both ends of the support rod body 01 are supported and connected to the derrick, the device can be normally disassembled and assembled, and has strong adaptability. In addition, through the corresponding layout of the arc segment A21 fixed to the U-shaped frame 11 and the arc segment B22 fixed to the plate frame 12, the arc segment A21 and the arc segment B22 can be adaptively and synchronously assembled and disassembled when the U-shaped frame 11 and the plate frame 12 are assembled and disassembled, making the overall disassembly and assembly steps simple and quick.

[0058] like Figure 5 、 Figure 7 and Figure 8 As shown, an adjusting screw 13 is threadedly installed in the screw hole 121 on the plate frame 12, and a guide rod B14 is slidably installed in the mounting hole B122 on the plate frame 12. The first driving mechanism 3 includes a U-shaped seat B31, a pair of driving rollers 32, a pair of pulleys A33, a driving motor A34, a pulley B35 and a transmission belt 36.

[0059] Among them, the U-shaped seat B31 is rotatably connected to the end of the adjusting screw 13 and is fixed to the end of the guide rod B14. The two drive rollers 32 are symmetrically rotatably installed in the U-shaped seat B31. The drive motor A34 is fixed in the U-shaped seat B31 through the bracket 341. The pulley B35 is fixed on the output shaft of the drive motor A34. The two drive rollers 32 are provided with an annular groove 321. The pulleys A33 are respectively fixed in the annular groove 321. The transmission belt 36 is transmission-type mounted on the pulley B35 and the two pulleys A33.

[0060] By pinching the handle on the adjusting screw 13 and applying force to rotate the adjusting screw 13, the first drive mechanism 3 can be driven to move and adjust as a whole. When the drive roller 32 is adjusted to a state of contact and fit with the surface of the support rod body 01, the first drive mechanism 3 is moved and assembled into place. The drive motor A34 is driven, and its output shaft drives the pulley B35 to rotate. The rotating pulley B35 drives the transmission belt 36 to operate. The transmission belt 36 drives the two pulleys A33 to rotate synchronously, thereby driving the two drive rollers 32 to roll along the surface of the support rod body 01, providing drive for the sleeve frame 1 to move along the surface of the support rod body 01.

[0061] The driving method is to use a synchronous pulley group consisting of pulley A33, pulley B35 and transmission belt 36 to drive the two driving rollers 32 to rotate. Since there is tooth engagement between the pressure roller 37 and the pulley B35 and pulley A33 respectively, transmission slippage is avoided, ensuring that the rotation of the two driving rollers 32 remains basically synchronized, thereby realizing two-point synchronous drive. When cleaning the surface of the support rod body 01, it can cope with high-load and long-term mobile operations, effectively avoid energy loss while maintaining stable power transmission, and maximize the drive rate. At the same time, the synchronous pulley group is integrated into the U-shaped seat B31, replacing the traditional complex drive device, which contributes to the compact design of the equipment, makes the equipment occupy less space, and is suitable for the narrow and limited space in the derrick.

[0062] In addition, pressure rollers 37 are rotatably installed on both sides of the pulley B35 in the U-shaped seat B31. The two pressure rollers 37 are in contact with each other to press the pressure rollers 37 in a V shape onto the pulley B35, thereby increasing the meshing contact area between the pulley B35 and the transmission belt 36 and ensuring that the transmission is more stable and efficient.

[0063] like Figure 5 and Figure 9As shown, the U-shaped frame 11 is formed by three plate bodies 111 fixed in one piece, and the three plate bodies 111 are provided with mounting holes A114, and a guide rod A115 is slidably installed in each mounting hole A114, and a U-shaped seat A112 is fixed at the end of the guide rod A115, and a pair of pressure wheels 113 are rotatably installed on the U-shaped seat A112, and a compression spring 116 is mounted on the outside of the guide rod A115, one end of the compression spring 116 is fixed to the surface of the plate body 111, and the other end is fixed to the surface of the U-shaped seat A112, which is used to support the pressure wheel 113 to press on the side surface of the support rod body 01.

[0064] When the sleeve seat 1 is installed on the support rod body 01, the elastic force of the compression spring 116 is used to push the U-shaped seat A112 closer to the support rod body 01, so that each pressure wheel 113 is firmly pressed on the corresponding side surface of the support rod body 01, so that the device can be firmly clamped on the support rod body 01. At the same time, the pressure wheel 113 on the opposite side of the plate frame 12 is pressed on the surface of the support rod body 01 to form a traction force, ensuring that the driving roller 32 can be closely abutted against the surface of the support rod body 01, thereby generating effective driving friction to drive the entire device to move. At the same time, each pressure wheel 113 is rotatably installed and can roll along the surface of the support rod body 01 when the device moves, ensuring that the movement process of the device is sufficiently stable.

[0065] See also Figure 5 and Figure 6 , a self-clamping locking mechanism 7 is provided on the plate frame 12, which includes a vertical seat plate 71, a clamping rod 72 and an arc-shaped extrusion head 73. Vertical seat plates 71 are fixed on the inner surface of the plate frame 12 on both sides of the U-shaped seat B31. Slide holes 711 are provided on the two vertical seat plates 71. Clamping rods 72 are slidably inserted in the two slide holes 711. Arc-shaped extrusion heads 73 are fixed on the ends of the two clamping rods 72 close to each other. Reset springs 75 are sleeved on the outside of the two clamping rods 72. One end of the reset spring 75 is fixed to the side of the vertical seat plate 71, and the other end is fixed to the arc-shaped extrusion head 73.

[0066] There are clamping holes 701 on the plate bodies 111 on both sides of the U-shaped frame 11, and wedge blocks 74 that are squeezed and matched with the arc-shaped extrusion heads 73 are fixed on both sides of the U-shaped seat B31. When the adjusting screw 13 is screwed to move the U-shaped seat B31 into place, the wedge blocks 74 squeeze the corresponding arc-shaped extrusion heads 73, pushing the clamping rods 72 to snap into the corresponding clamping holes 701, adaptively fastening the plate frame 12 and the U-shaped frame 11 to assemble the sleeve seat 1 as a whole.

[0067] When the sleeve frame 1 and the annular frame 2 are specifically installed, the U-shaped frame 11 and the arc segment A21 are first installed on the support rod body 01, and then the plate frame 12 is assembled and covered on the U-shaped frame 11 and pressed. Subsequently, the U-shaped seat B31 is pushed toward one side of the support rod body 01 by screwing the adjusting screw 13 until the driving roller 32 is in close contact with the outer surface of the support rod body 01. At this time, the entire first driving mechanism 3 is in the installed position. During the movement of the U-shaped seat B31, the wedge blocks 74 on both sides of the U-shaped seat B31 squeeze and push the arc extrusion head 73 respectively, and then push the clamping rod 72 to gradually move toward one side of the plate body 111. The reset spring 75 is compressed and accumulates force. Finally, when the first driving mechanism 3 is installed as a whole, the clamping rod 72 is matched and inserted into the clamping hole 701, thereby realizing the clamping and fixation of the plate frame 12 and the U-shaped frame 11. At the same time, the arc segment A21 and the arc segment B22 are adaptively assembled into the annular frame 2.

[0068] Among them, the inclined surface of the wedge block 74 is squeezed and matched with the arc-shaped part of the arc-shaped extrusion head 73 to ensure a smooth pushing process and avoid obstruction and jamming. After the first drive mechanism 3 is assembled in place, the adjusting screw 13 and the screw hole 121 are also anti-loosening. The specific anti-loosening treatment method adopts the existing technology and is no longer disclosed in this application, so as to avoid the U-shaped seat B31 from retreating, thereby ensuring that the wedge block 74 continues to push and resist the arc-shaped extrusion head 73, and can prevent the card rod 72 from arbitrarily falling out of the sliding hole 711, thereby ensuring the firmness of the sleeve seat 1 and the annular frame 2 during assembly and the stability during operation.

[0069] During disassembly, the adjusting screw 13 is screwed in the reverse direction to drive the U-shaped seat B31 gradually away from the support rod body 01, and the wedge block 74 gradually releases the resistance to the arc-shaped extrusion head 73. Under the elastic reset action of the reset spring 75, the clamping rod 72 can be driven to slowly disengage from the clamping hole 701, so that the clamping connection between the U-shaped frame 11 and the plate frame 12 is cancelled, so that the sleeve frame seat 1 and the annular frame 2 can be disassembled at the same time.

[0070] By providing a self-locking locking mechanism 7 on the plate frame 12, when the first driving mechanism 3 is assembled in place, the wedge block 74 is used to push the arc-shaped extrusion head 73 to prompt the locking rod 72 to be inserted into the locking hole 701, thereby realizing the assembly of the U-shaped frame 11 and the plate frame 12 and the assembly of the arc segment A21 and the arc segment B22. When the first driving mechanism 3 is retracted and adjusted, the elastic reset of the reset spring 75 is used to drive the locking rod 72 to disengage from the locking hole 701, thereby realizing the disassembly of the U-shaped frame 11 and the plate frame 12 and the separation of the arc segment A21 and the arc segment B22, thereby realizing a linkage disassembly and assembly mechanism.

[0071] like Figure 10 and Figure 12As shown, both sides of the arc segment A21 have limit groove sections A231, and both sides of the arc segment B22 have limit groove sections B232. When the arc segment A21 and the arc segment B22 are assembled into the annular frame 2, the limit groove sections A231 and the limit groove sections B232 on the same side are paired to form the annular limit groove 23 as a whole. The outer edge of the arc segment A21 has an arc-shaped tooth section A241, and the outer edge of the arc segment B22 has an arc-shaped tooth section B242. When the arc segment A21 and the arc segment B22 are assembled into the annular frame 2, the arc-shaped tooth section A241 and the arc-shaped tooth section B242 are paired to form the gear ring 24 as a whole.

[0072] The second drive mechanism 4 includes a U-shaped sleeve 41, a gear 43, a worm wheel 44, a worm 46, and a drive motor B47. The U-shaped sleeve 41 is mounted on the annular frame 2. The guide wheels 411 rotatably mounted on both sides of the U-shaped sleeve 41 are respectively clamped into the annular limiting grooves 23 on the corresponding sides, playing a role. At the same time, when the U-shaped sleeve 41 rotates around the annular frame 2, the guide wheels 411 roll within the annular limiting grooves 23, reducing friction and ensuring a smoother movement process. A shaft 42 is rotatably mounted on the U-shaped sleeve 41. The gear 43 is fixedly mounted on the shaft 42 and meshes with the gear ring 24. The worm wheel 44 is fixed to one end of the shaft 42.

[0073] The worm 46 is rotatably mounted on the side of the U-shaped sleeve 41 through a pair of side frames 45 . The worm 46 is fixed to one of the side frames 45 , and the output shaft is fixed to one end of the worm 46 . The worm 46 is meshed with the worm wheel 44 .

[0074] The output shaft of the driving motor B47 drives the worm 46 to rotate, and the rotating worm 46 engages with the worm wheel 44 to drive the shaft 42 and the gear 43 to rotate. Under the limiting action of the guide wheels 411 on both sides and the annular limiting groove 23, the rotating gear 43 engages and drives the gear ring 24, and then drives the U-shaped sleeve 41 in reverse to rotate along the annular frame 2, and drives the high-pressure steam nozzle 6 to rotate around the support rod body 01, thereby achieving surface cleaning of the support rod body 01.

[0075] In addition, the one-way transmission effect of the worm 46 and the side frame 45 plays a self-locking role when the drive motor B47 is not working, thereby preventing the U-shaped sleeve 41 from deflecting arbitrarily and causing the high-pressure steam nozzle 6 to lose its perpendicular state with the side surface of the support rod body 01.

[0076] like Figure 10-12As shown, the movable frame module 5 includes a wire cylinder guide rail 51, a drive motor C52, a cantilever 53 and a vertical arm 54. The wire cylinder guide rail 51 is fixed at the end of the U-shaped sleeve 41. The wire cylinder guide rail 51 has a movable seat 511 that can move in a direction perpendicular to the length of the support rod body 01. The drive motor C52 is fixed on the movable seat 511. The cantilever 53 is fixed on the output shaft of the drive motor C52. The vertical arm 54 is fixed on the end of the cantilever 53 and is arranged in an L-shaped structure with the cantilever 53. The high-pressure steam nozzle 6 is fixed at the end of the vertical arm 54.

[0077] By driving the motor C52, its output shaft can drive the cantilever 53 and the vertical arm 54 to swing, and then drive the high-pressure steam nozzle 6 to switch and adjust the position on both sides of the sleeve frame seat 1, which is conducive to two-way movement cleaning. At the same time, it also ensures that the high-pressure steam nozzle 6 can reach the extreme positions on both sides of the strut body 01 to clean the connection between the strut body 01 and the derrick, avoiding omission of the cleaning area. By working through the wire cylinder guide rail 51, the movable seat 511 thereon can move laterally to drive the high-pressure steam nozzle 6 to move laterally.

[0078] The piping system 8 includes a shaft tube 81, a delivery pipe 82, an adapter sleeve 83 and a connecting pipe 84. The shaft tube 81 is fixed on the cantilever 53 and is coaxially arranged with the output shaft of the drive motor C52. One end of the delivery pipe 82 is rotatably connected to the top of the shaft tube 81 through the adapter sleeve 83, and the other end is connected to the high-pressure steam cleaning machine. A hole 531 is provided on the cantilever 53. One end of the L-shaped connecting pipe 84 is fixedly connected to the shaft tube 81, and the other end passes through the hole 531 to communicate with the high-pressure steam nozzle 6.

[0079] The high-temperature and high-pressure steam generated by the high-pressure steam cleaning machine is transported to the shaft tube 81 by the delivery pipe 82, and then transmitted to the high-pressure steam nozzle 6 by the connecting pipe 84, thereby realizing the supply of high-temperature and high-pressure steam. In addition, the shaft tube 81 and the output shaft of the wire cylinder guide rail 51 are coaxially arranged, and the delivery pipe 82 is rotatably connected to the shaft tube 81, which can avoid the delivery pipe 82 from being twisted due to the rotation adjustment of the shaft tube 81. In addition, the shaft tube 81 and the connecting pipe 84 are metal pipes, which can provide additional support for the high-pressure steam nozzle 6 and ensure the stability of the high-pressure steam nozzle 6 during cleaning. The hose used in the delivery pipe 82 has the ability to bend and deform easily, thereby adapting to the position change of the device.

[0080] After the high-pressure steam nozzle 6 is rinsed and cleaned, some dirt will still remain on the surface of the support rod body 01, causing secondary pollution and affecting the cleaning effect. Figure 16 As shown, the four side surfaces of the brace body 01 are defined as side a 011 , side b 012 , side c 013 and side d 014 , and the span of the transverse path 02 is greater than the width of the side surface on any side of the brace body 01 .

[0081] After all four side surfaces of the support rod body 01 are cleaned, take the high-pressure steam nozzle 6 facing the a side 011 as an example. When the high-pressure steam nozzle 6 is located on both sides of the transverse path 02, the high-temperature and high-pressure steam sprayed by the high-pressure steam nozzle 6 exceeds the surface of the a side 011. Figure 15 As indicated by the arrows in the figure, the high-temperature and high-pressure steam exceeding the range will flush away the secondary attached dirt on the b side 012 or the d side 014. Similarly, when the high-pressure steam nozzle 6 is facing the b side 012, the secondary attached dirt on the a side 011 or the c side 013 can be flushed away. When the high-pressure steam nozzle 6 is facing the c side 013, the secondary attached dirt on the b side 012 or the d side 014 can be flushed away. When the high-pressure steam nozzle 6 is facing the d side 014, the secondary attached dirt on the c side 013 or the a side 011 can be flushed away, thereby achieving secondary cleaning of the surface of the support rod body 01, thereby effectively avoiding the re-attachment of dirt and causing pollution, and further ensuring the quality of the cleaning process.

[0082] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
