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 for oil drilling equipment are important components of the derrick structure. They are made of high-strength steel. Their main function is to enhance the overall stability and rigidity of the derrick and ensure that the derrick can maintain 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 types and design requirements of the derrick, and 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 respectively fixedly connected to the derrick body.

[0003] The operating environment of the derrick is harsh, and various impurities are easily attached to the surface of the support rod body 01, such as oil and dust in the drilling process and corrosive particles in industrial waste gas. The long-term accumulation of these impurities will accelerate the metal corrosion of the support rod body 01, reduce the structural strength, and endanger the safety of the derrick; oil and dust will also affect the adhesion of the coating of the support rod body 01, making the protective layer ineffective. Regular cleaning of the surface of the support rod body 01 can remove impurities in time, delay the corrosion process, ensure the integrity of the coating, and ensure the stability of the derrick and the support rod body 01 structure.

[0004] The installation position of the derrick support pole is usually high in the air. The traditional cleaning method is mainly manual high-altitude cleaning. Due to the complex structure and narrow space of the derrick, the cleaning personnel are prone to collision, squeezing and falling when climbing and moving between the complex structures. The cleaning is difficult and the installation coefficient is low. In addition, it is difficult to unify the intensity and method of manual cleaning, which is easy to leave cleaning dead corners, greatly reducing the cleaning effect and inefficient, which will seriously affect the normal operation progress of oil drilling. Comprehensive considerations show that manual cleaning has many disadvantages. Summary of the invention

[0014] Clamping holes are provided on the plates on both sides of the U-shaped frame. Wedge-shaped blocks that are in extrusion fit with the arc-shaped extrusion heads are respectively fixed on both sides of the U-shaped seat B. When the adjusting screw is rotated to move and assemble the U-shaped seat B in place, the wedge-shaped blocks extrude the corresponding arc-shaped extrusion heads, pushing the clamping rods to be inserted into the corresponding clamping holes, and adaptively fastening and assembling the plate frame and the U-shaped frame into an integral sleeve seat.

[0015] Preferably, both sides of the arc segment A have limiting groove segments A, and both sides of the arc segment B have limiting groove segments B. When the arc segment A and the arc segment B are assembled into an annular frame, the limiting groove segments A and B on the same side are paired into an integral annular limiting groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0020] The equipment provided by the present invention can be adaptively installed on the support rod body. The high-temperature steam generated by the high-pressure steam cleaner arranged on the ground is remotely transmitted to the high-pressure steam nozzle through the pipeline system to perform high-temperature steam flushing and cleaning treatment on the surface of the support rod body. The first driving mechanism drives the sleeve seat to feed along the length direction of the support rod body, and the moving frame group module drives the high-pressure steam nozzle to perform lateral adjustment, realizing the two-axis moving cleaning operation of the high-pressure steam nozzle. After cleaning one surface of the support rod body, the second driving mechanism drives the high-pressure steam nozzle to rotate around the support rod body to change the surface, which can effectively replace manual labor for high-altitude cleaning operations, improve the cleaning efficiency, and have a high safety factor.

[0021] When the high-pressure steam nozzle in the present invention performs mobile cleaning treatment on the surface of the support rod body, its cleaning track is a zigzag shape of bending back and forth, and the range where the high-pressure steam nozzle sprays steam for cleaning is an approximately circular area. Cleaning operations are carried out along the zigzag track to ensure that the cleaning ranges of the high-pressure steam nozzle on two adjacent lateral paths overlap, so as to ensure that the cleaning surface sufficiently covers the surface of the support rod body, avoid cleaning dead corners, and effectively improve the cleaning effect.

[0022] By arranging the high-pressure steam nozzle perpendicular to the surface to be cleaned in the present invention, the high-temperature steam ejected from the high-pressure steam nozzle acts on the target area intensively, reducing the energy loss caused by diffusion to the surrounding area, and then generating a large impact directly acting on the stain surface, 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 sets both the sleeve seat and the annular frame to be split-type. During disassembly and assembly, the sleeve 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, with strong adaptability. In addition, through the corresponding layout of fixing the arc segment A to the U-shaped frame and the arc segment B to the plate frame, the arc segment A and the arc segment B can be adaptively disassembled and assembled synchronously when the U-shaped frame and the plate frame are disassembled and assembled, making the overall disassembly and assembly steps simple and fast.

[0024] In the present invention, by providing a self-locking mechanism on the plate frame, while assembling the first driving mechanism in place, the wedge block is used to push the arc-shaped extrusion head to cause the clamping rod to insert into the clamping hole, 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 return spring is used to drive the clamping rod to disengage from the clamping hole, 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.

[0027] Please refer to Figures 1 - 14 , the present invention provides a surface treatment device for the derrick support rod of oil drilling and production equipment. The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] The present processing device includes a sleeve base 1 that can be fitted onto the pole body 01, a ring-shaped frame 2 installed outside the sleeve base 1, a second driving mechanism 4 sleeved on the ring-shaped frame 2 and capable of rotating and adjusting around the pole body 01, and a high-pressure steam nozzle 6 installed on the side of the second driving mechanism 4 through a moving frame group module 5. A first driving mechanism 3 is provided on the sleeve base 1. The first driving mechanism 3 is used to drive the sleeve base 1 to move along the length direction of the pole body 01. The second driving mechanism 4 is used to drive the high-pressure steam nozzle 6 to rotate and adjust around the pole body 01 to realize the switching of the cleaning surface, so as to clean the four sides of the pole body 01 respectively. The moving frame group module 5 can drive the high-pressure steam nozzle 6 to perform lateral adjustment in a direction perpendicular to the length direction of the pole body 01.

[0029] The high-pressure steam nozzle 6 is connected to a high-pressure steam cleaner through a pipeline system 8. Among them, the high-pressure steam cleaner adopts the existing technology, and its specific structure and working principle will not be elaborated in detail. The high-pressure steam cleaner is placed on the ground. Under the action of the high-pressure pump inside it, the pipeline system 8 is used to convey high-pressure steam for a long distance to the high-pressure steam nozzle 6 for flushing. High-pressure steam sprays out from the high-pressure steam nozzle 6. Due to the high temperature and pressure of the steam, when it sprays onto the surface of the pole body 01, it will generate a strong impact force and thermal effect. The high temperature softens and decomposes impurities such as oil stains and reduces their adhesion to the object surface. At the same time, the impact force of the high-pressure steam can wash away dust, corrosive particles and softened stains, achieving the purpose of cleaning the outer surface of the pole body 01.

[0030] The first driving mechanism 3 drives the sleeve base 1 to feed along the length direction of the pole body 01, and the moving frame group module 5 drives the high-pressure steam nozzle 6 to perform lateral adjustment, realizing the two-axis moving cleaning operation of the high-pressure steam nozzle 6. When the high-pressure steam nozzle 6 performs mobile cleaning on the surface of the pole body 01, as Figure 13 shown, its cleaning trajectory is a zigzag shape of bending and reciprocating, and the zigzag trajectory is composed of a lateral path 02 and a feeding path along the length direction of the pole body 01.

[0031] Since the range where the high-pressure steam nozzle 6 sprays steam for cleaning is an approximately circular area, as Figure 14 shown, define the spraying range of the high-pressure steam nozzle 6 on one of the lateral paths 02 as the cleaning area A03, and define the spraying range of the high-pressure steam nozzle 6 on the adjacent lateral path 02 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 lateral path 02 is greater than the width of any side surface of the pole body 01, ensuring that the lateral movement span of the high-pressure steam nozzle 6 is sufficient to cover the width of the pole body 01. When cleaning any side surface of the pole body 01, ensure that the working range of the high-pressure steam nozzle 6 is sufficient to cover the surface of the pole body 01.

[0032] When the high-pressure steam nozzles 6 are respectively aligned with the four side surfaces of the support rod body 01 for cleaning, the high-pressure steam nozzles 6 are perpendicular to the corresponding side surfaces of the sleeve frame base 1, so that the high-temperature steam ejected from the high-pressure steam nozzles 6 acts concentratedly on the target area, reducing the energy loss caused by diffusion to the surrounding area, and then generating a large impact directly acting on the stain surface, which helps to break the adhesion between the stain and the cleaning surface and improve the cleaning effect on stubborn stains.

[0033] Please refer to Figure 2 、 Figure 3 and Figure 10 As shown in the figure, the sleeve frame base 1 is composed of a U-shaped frame 11 and a plate frame 12, 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, the arc segment B22 is fixed on the plate frame 12 through a fixed bracket 101, and when the U-shaped frame 11 and the plate frame 12 are assembled into the sleeve frame base 1, the arc segment A21 and the arc segment B22 are adaptively assembled into the annular frame 2 in a paired manner.

[0034] Both the sleeve frame base 1 and the annular frame 2 are set as split types. During disassembly and assembly, the sleeve frame base 1 and the annular frame 2 can be disconnected to form a gap for the support rod body 01 to pass through. Thus, 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, with strong adaptability. In addition, through the corresponding layout of fixing the arc segment A21 to the U-shaped frame 11 and the arc segment B22 to the plate frame 12, the arc segment A21 and the arc segment B22 can be adaptively and synchronously disassembled and assembled when the U-shaped frame 11 and the plate frame 12 are disassembled and assembled, making the overall disassembly and assembly steps simple and fast.

[0035] As Figure 5 、 Figure 7 and Figure 8 shown, an adjusting screw rod 13 is penetratingly and fittingly screwed in the screw hole 121 on the plate frame 12, a guide rod B14 is slidably penetrated and installed in the mounting hole B122 on the plate frame 12, and the first driving mechanism 3 includes a U-shaped seat B31, a pair of driving rollers 32, a pair of pulley A33, a driving motor A34, a pulley B35 and a transmission belt 36.

[0036] Among them, the U-shaped seat B31 is rotatably connected to the end of the adjusting screw rod 13 and fixed to the end of the guide rod B14. The two driving rollers 32 are symmetrically and rotatably installed in the U-shaped seat B31. The driving motor A34 is fixed in the U-shaped seat B31 through a bracket 341. The pulley B35 is fixed on the output shaft of the driving motor A34. Ring grooves 321 are provided on both driving rollers 32, and the pulley A33 are respectively fixedly sleeved in the ring grooves 321. The transmission belt 36 is transmissionally sleeved on the pulley B35 and the two pulley A33.

[0037] By pinching the handle on the adjusting screw rod 13 and exerting force to twist the adjusting screw rod 13, the entire first driving mechanism 3 can be driven to move and adjust. When the driving roller 32 is adjusted to be in contact with and fit against the surface of the support rod body 01, it means that the first driving mechanism 3 is assembled in place. The driving motor A34 operates, and its output shaft drives the pulley B35 to rotate. The rotating pulley B35 drives the transmission belt 36 to operate, and the transmission belt 36 drives the two pulleys A33 to rotate synchronously, thereby driving the two driving rollers 32 to roll along the surface of the support rod body 01, providing drive for the sleeve frame seat 1 to walk along the surface of the support rod body 01.

[0038] Using the synchronous pulley group composed of the pulley A33, pulley B35, and transmission belt 36 to drive the two driving rollers 32 to rotate as the driving method, since there are tooth meshes between the pressure roller 37 and the pulley B35 and the pulley A33 respectively, the phenomenon of transmission slip is avoided, ensuring that the rotation of the two driving rollers 32 is basically synchronous, thus realizing two-point synchronous drive. When cleaning the surface of the support rod body 01, it can handle mobile operations with high load and long-term operation, effectively avoiding energy loss while maintaining stable power transmission, maximizing the driving efficiency. At the same time, this synchronous pulley group is integrally assembled in the U-shaped seat B31, replacing the traditional complex driving device, which helps the compact design of the equipment, enables the equipment to occupy less space, and is suitable for the narrow and limited space inside the derrick.

[0039] In addition, pressure rollers 37 are respectively rotatably installed on both sides of the pulley B35 inside the U-shaped seat B31, and the two pressure rollers 37 are both in contact with the pressure roller 37 to press the pressure roller 37 against the pulley B35 in a V shape, increasing the meshing contact area between the pulley B35 and the transmission belt 36 and ensuring more stable and efficient transmission.

[0040] As Figure 5 and Figure 9 shown, the U-shaped frame 11 is integrally fixed by three plate bodies 111. Mounting holes A114 are provided on all three plate bodies 111. Guide rods A115 are slidably penetrated and installed in each mounting hole A114. U-shaped seats A112 are fixed at the ends of the guide rods A115. A pair of pressure wheels 113 are rotatably installed on each U-shaped seat A112. Compression springs 116 are sleeved outside the guide rods A115. One end of each 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, used to support the pressure wheels 113 to press tightly against the side surface of the support rod body 01.

[0041] When installing the sleeve base 1 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 firmly presses on the corresponding side surface of the support rod body 01, enabling the device to be firmly clamped on the support rod body 01. At the same time, the pressure wheels 113 on the side of the plate frame 12 press on the surface of the support rod body 01 to form a traction force, ensuring that the driving roller 32 can be in close contact with 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 during the movement of the device, ensuring that the movement process of the device is stable enough.

[0042] Please refer to Figure 5 and Figure 6 As shown in FIGS. and, a self-locking mechanism 7 is provided on the plate frame 12. The self-locking mechanism 7 includes a vertical seat plate 71, a clamping rod 72, and an arc-shaped extrusion head 73. Vertical seat plates 71 are respectively 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 both vertical seat plates 71, and clamping rods 72 are slidably inserted into both slide holes 711. Arc-shaped extrusion heads 73 are fixed on the ends of the two clamping rods 72 close to each other. Return springs 75 are sleeved outside both clamping rods 72. One end of the return 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.

[0043] Clamping holes 701 are provided on the plate bodies 111 on both sides of the U-shaped frame 11. Wedge blocks 74 that are extrusion-fitted with the arc-shaped extrusion heads 73 are respectively fixed on both sides of the U-shaped seat B31. When the adjusting screw 13 is rotated to move and assemble the U-shaped seat B31 in place, the wedge block 74 squeezes the corresponding arc-shaped extrusion head 73, pushing the clamping rod 72 to be inserted into the corresponding clamping hole 701, and adaptively fastening and assembling the plate frame 12 and the U-shaped frame 11 into the sleeve base 1 as a whole.

[0044] When specifically installing the sleeve base 1 and the annular frame 2, first, the U-shaped frame 11 and the arc section A21 are sleeved on the support rod body 01, and then the plate frame 12 is assembled and covered on the U-shaped frame 11 and pressed tightly. Subsequently, by rotating the adjusting screw 13, the U-shaped seat B31 is pushed to feed towards the support rod body 01 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 state. During the movement of the U-shaped seat B31, the wedge blocks 74 on both sides of the U-shaped seat B31 respectively squeeze and push the arc-shaped extrusion heads 73, further pushing the clamping rods 72 to gradually move towards the side of the plate body 111, and the return springs 75 are compressed and store energy. Finally, when the entire first driving mechanism 3 is installed in place, the clamping rods 72 are inserted into the clamping holes 701 in a matching manner, realizing the clamping and fixing of the plate frame 12 and the U-shaped frame 11. At the same time, the arc section A21 and the arc section B22 are adaptively assembled into the annular frame 2.

[0045] Among them, the inclined surface of the wedge block 74 is in extrusion fit with the arc part of the arc-shaped extrusion head 73, ensuring a smooth pushing process and avoiding blockage and jamming. After the first driving mechanism 3 is assembled in place, the adjusting screw 13 and the screw hole 121 are also anti-loosening treated. The specific anti-loosening treatment method adopts the existing technology and will not be disclosed in this application to avoid the U-shaped seat B31 from retracting, thereby ensuring that the wedge block 74 continuously pushes against the arc-shaped extrusion head 73, preventing the clamping rod 72 from randomly disengaging from the sliding hole 711, and further ensuring the firmness during the assembly of the sleeve frame seat 1 and the annular frame 2 and the stability during operation.

[0046] During disassembly, reverse-rotate the adjusting screw 13 to drive the U-shaped seat B31 to gradually move away from the support rod body 01, and the resistance of the wedge block 74 to the arc-shaped extrusion head 73 is gradually released. Under the elastic reset action of the return spring 75, the clamping rod 72 can be driven to slowly disengage from the clamping hole 701, canceling the clamping connection between the U-shaped frame 11 and the plate frame 12, so as to disassemble the sleeve frame seat 1 and the annular frame 2 simultaneously.

[0047] By providing a self-locking mechanism 7 on the plate frame 12, while the first driving mechanism 3 is assembled in place, the wedge block 74 is used to push the arc-shaped extrusion head 73 to drive the clamping rod 72 to insert into the clamping hole 701, realizing the assembly of the U-shaped frame 11 and the plate frame 12 and the assembly of the arc section A21 and the arc section B22. When the first driving mechanism 3 is retracted and adjusted, the elastic reset of the return spring 75 is used to drive the clamping rod 72 to disengage from the clamping hole 701, realizing the disassembly of the U-shaped frame 11 and the plate frame 12 and the separation of the arc section A21 and the arc section B22, realizing a linkage disassembly and assembly mechanism.

[0048] As Figure 10 and Figure 12 shown, both sides of the arc section A21 have a limit groove section A231, and both sides of the arc section B22 have a limit groove section B232. When the arc section A21 and the arc section B22 are assembled into the annular frame 2, the limit groove section A231 and the limit groove section B232 on the same side are paired into the annular limit groove 23 as a whole. An arc tooth section A241 is provided on the outer edge of the arc section A21, and an arc tooth section B242 is provided on the outer edge of the arc section B22. When the arc section A21 and the arc section B22 are assembled into the annular frame 2, the arc tooth section A241 and the arc tooth section B242 are paired into the tooth ring 24 as a whole.

[0049] The second driving mechanism 4 includes a U-shaped socket 41, a gear 43, a worm gear 44, a worm 46 and a driving motor B47. The U-shaped socket 41 is sleeved on the annular frame 2. Guide wheels 411 rotatably installed on both sides of the U-shaped socket 41 are respectively clamped in the corresponding annular limiting grooves 23 on the corresponding sides, playing a role. At the same time, when the U-shaped socket 41 rotates around the annular frame 2, the guide wheels 411 roll in the annular limiting grooves 23, reducing friction and ensuring a smoother movement process. A shaft rod 42 is rotatably installed on the U-shaped socket 41. The gear 43 is fixedly sleeved on the shaft rod 42 and correspondingly meshes with the toothed ring 24. The worm gear 44 is fixed on one end of the side of the shaft rod 42.

[0050] The worm 46 is rotatably installed on the side of the U-shaped socket 41 through a pair of side frames 45. The worm 46 is fixed on one of the side frames 45, and the output shaft is fixed to one end of the worm 46. The worm 46 correspondingly meshes with the worm gear 44.

[0051] By the operation of the driving motor B47, its output shaft drives the worm 46 to rotate. The rotating worm 46 meshes with and drives the worm gear 44, driving the shaft rod 42 and the gear 43 to rotate. Under the limiting effect of the two guide wheels 411 and the annular limiting grooves 23, the rotating gear 43 meshes with and drives the toothed ring 24, and then reversely drives the U-shaped socket 41 to rotate along the annular frame 2, driving the high-pressure steam nozzle 6 to rotate around the strut body 01, realizing the surface-changing cleaning of the strut body 01.

[0052] In addition, by utilizing the one-way transmission effect of the worm 46 and the side frames 45, when the driving motor B47 is not working, a self-locking effect is achieved, avoiding the U-shaped socket 41 from deflecting randomly and causing the high-pressure steam nozzle 6 to lose the perpendicular state with the side surface of the strut body 01.

[0053] As Figures 10 - 12 shown, the moving frame group module 5 includes a wire cylinder guide rail 51, a driving 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 socket 41. The wire cylinder guide rail 51 has a moving seat 511 that can move in a direction perpendicular to the length of the strut body 01. The driving motor C52 is fixed on the moving seat 511. The cantilever 53 is fixed on the output shaft of the driving motor C52. The vertical arm 54 is fixed at 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.

[0054] By driving the operation of the drive motor C52, its output shaft can drive the swing of the cantilever 53 and the vertical arm 54, and then can drive the high-pressure steam nozzle 6 to switch and adjust positions on both sides of the sleeve seat 1, which is beneficial to two-way moving 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 support rod body 01 to clean the connection between the support rod body 01 and the derrick, avoiding omission of the cleaning area. By the operation of the wire cylinder guide rail 51, the moving seat 511 thereon can move horizontally to drive the horizontal movement adjustment of the high-pressure steam nozzle 6.

[0055] The pipeline system 8 includes a shaft tube 81, a delivery pipe 82, a transfer sleeve 83 and a connecting pipe 84. The shaft tube 81 is fixed on the cantilever 53 and is arranged coaxially with the output shaft of the drive motor C52. One end of the delivery pipe 82 is rotatably and communicatively connected to the top of the shaft tube 81 through the transfer sleeve 83, and the other end is connected to the high-pressure steam cleaner. There is a hole 531 on the cantilever 53. One end of the L-shaped connecting pipe 84 is fixedly communicated with the shaft tube 81, and the other end passes through the hole 531 and is communicated with the high-pressure steam nozzle 6.

[0056] The high-temperature and high-pressure steam generated by the high-pressure steam cleaner 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 to realize the supply of high-temperature and high-pressure steam. In addition, the shaft tube 81 is arranged coaxially with the output shaft of the wire cylinder guide rail 51, and the delivery pipe 82 is rotatably connected to the shaft tube 81, which can avoid the situation that the delivery pipe 82 is twisted following the rotational adjustment of the shaft tube 81. In addition, the shaft tube 81 and the connecting pipe 84 are made of metal pipes, which can provide an additional supporting effect on the high-pressure steam nozzle 6 to ensure the stability of the high-pressure steam nozzle 6 during the cleaning work. The delivery pipe 82 is a flexible pipe with the ability of easy bending and deformation to adapt to the position change of the device.

[0057] Since after the high-pressure steam nozzle 6 flushes and cleans, some dirt will still remain on the surface of the support rod body 01, causing secondary pollution and affecting the cleaning effect, as Figure 16 shown, the four side surfaces of the support rod body 01 are defined as the a side 011, the b side 012, the c side 013 and the d side 014 in sequence. At the same time, the span of the horizontal path 02 is greater than the width of any side surface of the support rod body 01.

[0058] After all four side surfaces of the support rod body 01 are completely cleaned, taking 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 horizontal path 02 respectively, the range of the high-temperature and high-pressure steam ejected by the high-pressure steam nozzle 6 exceeds the surface of the a side 011, as Figure 15The arrow in indicates that the high-temperature and high-pressure steam beyond the range washes away the dirt secondarily attached to the b-side 012 or the d-side 014, and so on. When the high-pressure steam nozzle 6 faces the b-side 012, it can wash away the dirt secondarily attached to the a-side 011 or the c-side 013. When the high-pressure steam nozzle 6 faces the c-side 013, it can wash away the dirt secondarily attached to the b-side 012 or the d-side 014. When the high-pressure steam nozzle 6 faces the d-side 014, it can wash away the dirt secondarily attached to the c-side 013 or the a-side 011, realizing the secondary cleaning treatment of the surface of the support rod body 01, thereby effectively avoiding the reattachment of dirt and causing pollution, and further ensuring the quality of the cleaning treatment.

[0059] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
