Description

Technical Field

[0001] The present application relates to the technical field of pipe conveying and positioning, and in particular to a pressure wheel adjustment and limiting structure and an application method thereof. Background Art

[0002] When the pipe is transported in a directional manner after processing, two symmetrical pressing wheels will be installed on the traditional transport rails. The pipe passes through the two pressing wheels through the traction equipment. However, since the size and thickness of the pipe transported each time may be different, the axial width of the pressing wheel is usually increased, and the pressing wheel located above is made into an adjustable structure to adapt to pipes of different sizes and thicknesses.

[0003] During transportation, pipes are usually driven by traction equipment, and a traction motor is usually used in the traction equipment to provide a torque output source. The vibration generated by the traction motor when it is working will be transmitted to the pipes in transportation, causing the pipes to shake. Therefore, the pipes will be pressed against the lower pressure wheel through the adjustable upper pressure wheel. However, since the inside of the pipe is hollow, it is necessary to control the pressure of the upper pressure wheel to press the pipe.

[0004] Since there is an angle difference between the traction direction of the traction equipment and the rolling direction of the upper and lower pressure wheels during installation, although the angle difference is small, the pipe is usually long. As the traction equipment drives the pipe gradually away from the upper and lower pressure wheels, the pipe will shake greatly. The shaking pipe can easily cause production hazards, which is a deficiency. Summary of the invention

[0005] In order to improve the problem of large shaking of the pipe when passing through the upper pressing wheel and the lower pressing wheel, the present application provides a pressing wheel adjustment limit structure and an application method thereof.

[0006] In the first aspect, the present application provides a pressure wheel adjustment limit structure adopts the following technical solution:

[0007] A pressure wheel adjustment and limiting structure comprises a traction device, a fixed seat and a support frame, wherein an angle disk is rotatably provided on the fixed seat, a horizontal lower pressure wheel is rotatably provided on the angle disk, a pedestal tube is vertically slidably provided on the support frame, a limiting component for controlling the vertical sliding position of the pedestal tube is provided on the support frame, a cylinder seat coaxial with the angle disk is rotatably provided on the pedestal tube, a horizontal upper pressure wheel is rotatably provided on the cylinder seat, the upper pressure wheel is located above the lower pressure wheel, a correction component for driving the cylinder seat to rotate is provided on the pedestal tube, and the correction component is used to make the cylinder seat turn in the opposite direction to the angle disk.

[0008] By adopting the above technical scheme, workers pass the pipe through the lower pressing wheel and the upper pressing wheel, and fix one end of the pipe on the traction equipment, and then control the vertical sliding of the console tube through the limit assembly, so that the upper pressing wheel on the cylinder seat presses the pipe against the lower pressing wheel, and then the traction equipment pulls the pipe. The vibration generated during the traction process of the traction equipment causes the pipe to shake, and the shaking pipe drives the lower pressing wheel to rotate continuously around the axis of the angle disk through friction, and then the deviation correction part makes the cylinder seat and the angle disk turn in opposite directions, so that the upper pressing wheel and the lower pressing wheel turn in opposite directions, and the friction between the upper pressing wheel and the pipe hinders the shaking of the pipe, thereby reducing the shaking amplitude of the pipe during the traction process.

[0009] Optionally, the limiting assembly includes a hydraulic cylinder arranged on the support frame and electrically connected to the control system, the base tube is arranged on the piston rod of the hydraulic cylinder, an outer tube is arranged on the support frame, the outer tube is coaxially sleeved on the base tube, a clamping block is arranged on the base tube, an avoidance groove for the sliding of the clamping block is opened between the inner and outer side walls of the outer tube, and a control component for controlling the sliding position of the base tube is arranged on the clamping block.

[0010] By adopting the above technical solution, after the pipe is placed on the lower pressing wheel, the worker adjusts it according to the size and thickness of the pipe, controls the maximum sliding position of the pedestal tube through the control component, and then starts the hydraulic cylinder through the control system. The piston rod of the hydraulic cylinder drives the pedestal tube to descend, and the pedestal tube drives the clamping block to slide along the avoidance groove on the outer tube and approach the lower pressing wheel until the upper pressing wheel is pressed on the pipe, thereby achieving the fixing effect of the pipe in the vertical direction.

[0011] Optionally, the control member includes a limiting screw threadedly connected to the clamping block, a baffle is provided on the outer tube, the limiting screw abuts against the baffle, a locking nut is threadedly connected to the limiting screw, and the locking nut is used to abut against the clamping block.

[0012] By adopting the above technical solution, the worker turns the limit screw, adjusts the distance between the limit screw and the baffle, and then tightens the anti-loosening nut to control the maximum downward sliding distance of the console seat tube, so that the pipe is pressed and fixed while the pipe will not be damaged during the traction process.

[0013] Optionally, anti-slip cones are coaxially slidably arranged at both ends of the lower pressing wheel in the axial direction, and the diameter of the anti-slip cone gradually decreases from the end of the lower pressing wheel to the middle of the lower pressing wheel. A tensioning member is arranged between the anti-slip cone and the lower pressing wheel, and the tensioning member is used to control the pressure between the anti-slip cone and the pipe.

[0014] By adopting the above technical solution, when the pipe shakes during the traction process, the shaking pipe will cause the lower pressure wheel to rotate around the axis of the angle disk, and the anti-slip cone at the end of the rotating lower pressure wheel will abut against the side of the pipe, thereby reducing the bending deformation of the pipe and preventing the pipe from detaching from the lower pressure wheel. The tensioning piece will further prevent the shaking of the pipe by controlling the tension between the anti-slip cone and the pipe.

[0015] Optionally, the tensioning member includes a rotating shaft rotatably set on the angle disk, the lower pressure wheel is coaxially sleeved on the rotating shaft, a sleeve is coaxially rotatably set on the rotating shaft, the anti-slip cone is coaxially sleeved on the sleeve, a pipe groove for inserting the sleeve is opened at the end of the lower pressure wheel, an end ring plate is detachably set on the rotating shaft, and a compression spring is supported between the end ring plate and the sleeve.

[0016] By adopting the above technical solution, when the pipe shakes, the side of the pipe will abut and push the anti-slip cone, and the anti-slip cone will slide along the axial direction of the rotating shaft. At the same time, the compression spring is squeezed and deformed, and the restoring deformation force of the compression spring will hinder further shaking of the pipe.

[0017] Optionally, a shaft rod is coaxially arranged on the angle disk, a bearing is arranged between the angle disk and the fixed seat, the shaft rod rotates through the fixed seat, a base plate is coaxially arranged on the shaft rod, a brush electrically connected to the control system is arranged on the base plate, a resistance ring strip electrically connected to the control system is arranged on the fixed seat, and the brush is in contact with the resistance ring strip.

[0018] By adopting the above technical solution, when the angle disk rotates around the axis of the shaft rod, the shaft rod drives the brush to rotate synchronously through the base plate, and the rotating brush contacts the resistance ring at different positions, thereby changing the feedback signal obtained by the control system, making it easier for workers to understand the angle difference between the traction direction of the pipe and the rotation direction of the lower pressure wheel, and facilitating the subsequent adjustment of the traction direction of the pipe.

[0019] Optionally, the correction component includes a support plate arranged in the pedestal tube, a vertical shaft is coaxially arranged on the cylinder seat, the vertical shaft rotates through the support plate, a driven gear is coaxially arranged on the vertical shaft on the side of the support plate facing away from the cylinder seat, a correction motor electrically connected to the control system is arranged on the support plate, and a driving gear meshing with the driven gear is arranged on the output shaft of the correction motor.

[0020] By adopting the above technical solution, when the signal change caused by the resistance ring is transmitted to the control system, the control system starts the correction motor, and the output shaft of the correction motor drives the driven gear to rotate through the driving gear, and the driven gear drives the upper pressure wheel on the cylinder seat to rotate synchronously through the vertical axis, so that the upper pressure wheel and the lower pressure wheel turn in opposite directions, thereby reducing the shaking amplitude of the pipe.

[0021] Optionally, a cylinder electrically connected to a control system is provided on the fixing seat, and a wear-resistant block is provided on the piston rod of the cylinder, and the wear-resistant block is used to abut against the angle plate.

[0022] By adopting the above technical solution, when the signal change caused by the resistance ring is transmitted to the control system, the worker takes the middle value according to the signal difference fed back by the control system, and starts the cylinder when the middle value signal fed back by the resistance ring changes. The piston rod of the cylinder extends and drives the wear-resistant block to press on the angle disk, thereby slowing down the rotation speed of the angle disk and further reducing the shaking amplitude of the pipe.

[0023] In a second aspect, the present application provides an application method of a pressure wheel adjustment limit structure, which adopts the following technical solution:

[0024] An application method of a pressure wheel adjustment limit structure comprises the following steps:

[0025] S1, passing the pipe between the upper pressing wheel and the lower pressing wheel, and fixing one end of the pipe on the traction device;

[0026] S2, controlling the upper pressing wheel to approach the lower pressing wheel through the limiting assembly, so that the pipe is pressed tightly on the lower pressing wheel;

[0027] S3, the traction device pulls the pipe, and the vibration generated by the traction of the traction device causes the pipe to shake, and the shaking of the pipe is transmitted to the lower pressing wheel, and the shaking of the lower pressing wheel causes the angle plate to rotate around its axis, so that the angle plate continuously adjusts its angle as the pipe shakes;

[0028] S4. The deviation correcting member makes the cylinder seat and the angle disk turn in opposite directions, thereby making the upper pressing wheel and the lower pressing wheel turn in opposite directions. The friction between the upper pressing wheel and the pipe hinders the shaking of the pipe, thereby reducing the degree of shaking of the pipe.

[0029] By adopting the above technical solution, the shaking amplitude of the pipe during the traction process can be reduced by relying on the different rolling directions of the upper pressing wheel and the lower pressing wheel.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The worker passes the pipe between the lower pressing wheel and the upper pressing wheel, and fixes one end of the pipe on the traction equipment. Then, the worker controls the vertical sliding of the seat tube through the limit assembly, so that the upper pressing wheel on the cylinder seat presses the pipe against the lower pressing wheel. Then, the traction equipment pulls the pipe. The vibration generated during the traction process of the traction equipment causes the pipe to shake. The shaking pipe drives the lower pressing wheel to rotate continuously around the axis of the angle plate through friction. Then, the deviation correction part makes the cylinder seat and the angle plate turn in opposite directions, so that the upper pressing wheel and the lower pressing wheel turn in opposite directions. The friction between the upper pressing wheel and the pipe prevents the shaking of the pipe, thereby reducing the shaking amplitude of the pipe during the traction process.

[0032] 2. After the pipe is placed on the lower pressing wheel, the worker adjusts it according to the size and thickness of the pipe, controls the maximum sliding position of the table tube through the control part, and then starts the hydraulic cylinder through the control system. The piston rod of the hydraulic cylinder drives the table tube to descend, and the table tube drives the block to slide along the avoidance groove on the outer tube and approach the lower pressing wheel until the upper pressing wheel presses on the pipe, thereby achieving the fixing effect of the pipe in the vertical direction;

[0033] 3. When the pipe shakes during the traction process, the shaking pipe will cause the lower pressing wheel to rotate around the axis of the angle plate, and the anti-dropping cone at the end of the rotating lower pressing wheel will abut against the side of the pipe, thereby reducing the bending deformation of the pipe and preventing the pipe from escaping from the lower pressing wheel. The tensioner will further prevent the shaking of the pipe by controlling the tension between the anti-dropping cone and the pipe.

[0034] 4. When the signal change caused by the resistance ring is transmitted to the control system, the worker takes the middle value according to the signal difference fed back by the control system, and starts the cylinder when the middle value signal fed back by the resistance ring changes. The piston rod of the cylinder extends and drives the wear-resistant block to press against the angle plate, thereby slowing down the rotation speed of the angle plate and further reducing the shaking amplitude of the pipe.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0039] Example 1

[0040] The embodiment of the present application discloses a pressure wheel adjustment limit structure.

[0042] Reference Figure 1 and Figure 2 A limit assembly 8 for the vertical sliding position of the console seat tube 7 is arranged on the support frame 4. The limit assembly 8 includes a hydraulic cylinder 81 bolted to the support frame 4 and electrically connected to the control system. The seat tube 7 is bolted to the piston rod of the hydraulic cylinder 81. An outer tube 82 is bolted to the support frame 4. The outer tube 82 is coaxially sleeved on the seat tube 7. A block 83 with an L-shaped cross section is bolted to the seat tube 7. An avoidance groove 84 for the block 83 to slide is opened between the inner and outer side walls of the outer tube 82 along the axial direction of the outer tube 82.

[0043] Reference Figure 1 and Figure 2A control member 85 for controlling the sliding position of the console seat tube 7 is arranged on the block 83, and the control member 85 includes a limit screw 851 threadedly connected to the block 83, a baffle 852 is welded on the outer tube 82, and the baffle 852 is abutted by the limit screw 851, and a lock nut 853 is threadedly connected to the limit screw 851, and the lock nut 853 is used to abut the block 83.

[0044] The worker passes the pipe 1 between the upper pressing wheel 10 and the lower pressing wheel 6, and fixes one end of the pipe 1 on the traction device 2. Then, according to the size and thickness of the pipe 1, the worker turns the limit screw 851, adjusts the length of the limit screw 851 on the side of the baffle 852, and then tightens the anti-loosening nut 853 so that the anti-loosening nut 853 abuts against the block 83.

[0045] Then, the hydraulic cylinder 81 is started through the control system, and the piston rod of the hydraulic cylinder 81 drives the base tube 7 to descend and approach the lower pressing wheel 6, and the block 83 slides along the length direction of the avoidance groove 84 until the cylinder seat 9 drives the upper pressing wheel 10 to press the pipe 1 against the lower pressing wheel 6, thereby achieving preliminary fixation of the pipe 1, and then the limit screw 851 is turned again to fine-tune the pressure on the pipe 1.

[0046] Reference Figure 1 and Figure 2 A shaft 14 is coaxially welded on the angle disk 5, a bearing 15 is arranged between the angle disk 5 and the fixed seat 3, the shaft 14 rotates through the fixed seat 3, a base plate 16 is coaxially bolted on the shaft 14, the base plate 16 can be made of insulating material, a brush 17 electrically connected to the control system is bolted on the base plate 16, a resistance ring 18 electrically connected to the control system is bolted on the fixed seat 3, the resistance ring 18 can be made of a metal material with a small resistance value that changes with temperature, and the brush 17 is in contact with the resistance ring 18.

[0047] Reference Figure 1 and Figure 2 A cylinder 19 electrically connected to the control system is bolted to the fixed seat 3, and a wear-resistant block 20 is bolted to the piston rod of the cylinder 19. The wear-resistant block 20 is used to abut the outer wall of the angle plate 5. Anti-slip cones 12 are coaxially slidably arranged at both ends of the lower pressing wheel 6 in the axial direction. The diameter of the anti-slip cone 12 gradually decreases from the end of the lower pressing wheel 6 to the middle of the lower pressing wheel 6. A tensioning piece 13 is arranged between the anti-slip cone 12 and the lower pressing wheel 6. The tensioning piece 13 is used to control the pressure between the anti-slip cone 12 and the pipe 1.

[0048] Reference Figure 1 and Figure 2A mounting plate 21 is welded on the angle disk 5, the tensioning member 13 includes a horizontal rotating shaft 131 rotatably connected to the mounting plate 21, the lower pressure wheel 6 is coaxially sleeved on the rotating shaft 131, a sleeve 132 is coaxially rotatably sleeved on the rotating shaft 131, the anti-slip cone 12 is coaxially sleeved on the sleeve 132, both ends of the lower pressure wheel 6 are provided with pipe grooves 133 for inserting the sleeve 132, an end ring plate 134 is threadedly connected to the rotating shaft 131, and a compression spring 135 is supported between the end ring plate 134 and the sleeve 132.

[0049] When the traction device 2 pulls the pipe 1 to slide between the upper pressure wheel 10 and the lower pressure wheel 6, the vibration generated on the traction device 2 will be transmitted to the pipe 1, causing the pipe 1 to shake. The shaking pipe 1 drives the angle plate 5 to rotate around the axis of the shaft 14 through the lower pressure wheel 6, and the shaft 14 drives the brush 17 to rotate synchronously through the base plate 16. The brush 17 continuously slides on the resistance ring 18, thereby changing the resistance value fed back by the resistance ring 18.

[0050] As the base plate 16 drives the brush 17 to swing back and forth, the control system will obtain the resistance difference of the resistance ring 18 caused by the shaking of the pipe 1. When the brush 17 swings and again feeds back the intermediate data value of the resistance ring 18, the control system starts the cylinder 19. The piston rod of the cylinder 19 extends and presses the wear-resistant block 20 against the outer wall of the angle plate 5, thereby reducing the rotation speed of the angle plate 5.

[0051] The worker turns the end ring plate 134 to adjust the pressure of the compression spring 135, and the shaking pipe 1 will push the anti-slip cone 12 at both ends of the lower pressure wheel 6. The anti-slip cone 12 squeezes the compression spring 135 through the sleeve 132, and the compression spring 135 is deformed. The compression spring 135 restores the deformation force to prevent the pipe 1 from shaking, thereby reducing the shaking amplitude of the pipe 1.

[0052] Reference Figure 1 and Figure 2 A hard rubber layer 22 is coaxially sleeved on the upper pressure wheel 10, and a correcting member 11 for driving the cylinder seat 9 to rotate is arranged on the pedestal tube 7. The correcting member 11 is used to make the cylinder seat 9 and the angle disk 5 turn in opposite directions. The correcting member 11 includes a support plate 111 welded in the pedestal tube 7, and a vertical shaft 112 is coaxially welded on the cylinder seat 9, and the vertical shaft 112 rotates through the support plate 111.

[0053] Reference Figure 1 and Figure 2 A driven gear 113 is coaxially welded on the vertical shaft 112 of the support plate 111 on the side facing away from the cylinder seat 9, a correction motor 114 electrically connected to the control system is bolted to the support plate 111, and a driving gear 115 meshing with the driven gear 113 is bolted to the output shaft of the correction motor 114.

[0054] When the angle disc 5 rotates forward, the control system starts the correcting motor 114, and the output shaft of the correcting motor 114 drives the driving gear 115 to rotate. The driving gear 115 drives the cylinder seat 9 on the vertical shaft 112 to rotate in the opposite direction through the driven gear 113, so that the upper pressing wheel 10 and the lower pressing wheel 6 rotate in opposite directions, and the friction between the upper pressing wheel 10 and the pipe 1 further prevents the shaking of the pipe 1.

[0055] The implementation principle of Example 1 is: the worker passes the pipe 1 between the upper pressing wheel 10 and the lower pressing wheel 6, and fixes one end of the pipe 1 on the traction device 2, and then turns the limit screw 851 according to the size and thickness of the pipe 1, adjusts the length of the limit screw 851 on the side of the baffle 852, and then tightens the anti-loosening nut 853 so that the anti-loosening nut 853 abuts against the block 83.

[0056] Then, the hydraulic cylinder 81 is started through the control system, and the piston rod of the hydraulic cylinder 81 drives the base tube 7 to descend and approach the lower pressing wheel 6, and the block 83 slides along the length direction of the avoidance groove 84 until the cylinder seat 9 drives the upper pressing wheel 10 to press the pipe 1 against the lower pressing wheel 6, thereby achieving preliminary fixation of the pipe 1, and then the limit screw 851 is turned again to fine-tune the pressure on the pipe 1.

[0057] When the traction device 2 pulls the pipe 1 to slide between the upper pressure wheel 10 and the lower pressure wheel 6, the vibration generated on the traction device 2 will be transmitted to the pipe 1, causing the pipe 1 to shake. The shaking pipe 1 drives the angle plate 5 to rotate around the axis of the shaft 14 through the lower pressure wheel 6, and the shaft 14 drives the brush 17 to rotate synchronously through the base plate 16. The brush 17 continuously slides on the resistance ring 18, thereby changing the resistance value fed back by the resistance ring 18.

[0058] As the base plate 16 drives the brush 17 to swing back and forth, the control system will obtain the resistance difference of the resistance ring 18 caused by the shaking of the pipe 1. When the brush 17 swings and again feeds back the intermediate data value of the resistance ring 18, the control system starts the cylinder 19. The piston rod of the cylinder 19 extends and presses the wear-resistant block 20 against the outer wall of the angle plate 5, thereby reducing the rotation speed of the angle plate 5.

[0059] The worker turns the end ring plate 134 to adjust the pressure of the compression spring 135, and the shaking pipe 1 will push the anti-slip cone 12 at both ends of the lower pressure wheel 6. The anti-slip cone 12 squeezes the compression spring 135 through the sleeve 132, and the compression spring 135 is deformed. The compression spring 135 restores the deformation force to prevent the pipe 1 from shaking, thereby reducing the shaking amplitude of the pipe 1.

[0060] When the angle disc 5 rotates forward, the control system starts the correcting motor 114, and the output shaft of the correcting motor 114 drives the driving gear 115 to rotate. The driving gear 115 drives the cylinder seat 9 on the vertical shaft 112 to rotate in the opposite direction through the driven gear 113, so that the upper pressing wheel 10 and the lower pressing wheel 6 rotate in opposite directions, and the friction between the upper pressing wheel 10 and the pipe 1 further prevents the shaking of the pipe 1.

[0063] S1, passing the pipe 1 between the upper pressing wheel 10 and the lower pressing wheel 6, and fixing one end of the pipe 1 on the traction device 2;

[0064] S2. According to the size and thickness of the pipe 1, the limiting screw 851 is turned to adjust the length of the limiting screw 851 extending toward one end of the baffle 852, and then the locking nut 853 is tightened;

[0065] S3, twist the end ring plate 134 to adjust the elastic force of the compression spring 135;

[0066] S4, start the hydraulic cylinder 81 through the control system, the piston rod of the hydraulic cylinder 81 drives the base tube 7 to descend and approach the lower pressing wheel 6, until the upper pressing wheel 10 presses the pipe 1 onto the lower pressing wheel 6, and then screw the limit screw 851 again to fine-tune the anti-loosening nut 853;

[0067] S5, start the traction device 2, the traction device 2 drives the pipe 1 to slide between the lower pressing wheel 6 and the upper pressing wheel 10. When the pipe 1 shakes due to the vibration of the traction device 2, the pipe 1 drives the angle plate 5 to rotate through the lower pressing wheel 6. The angle plate 5 drives the brush 17 to slide back and forth on the resistance ring 18 through the shaft 14 and the base plate 16. The resistance feedback signal on the resistance ring 18 is transmitted to the control system;

[0068] S6, the control system starts the cylinder 19, the piston rod of the cylinder 19 extends and the wear-resistant block 20 abuts against the outer wall of the angle plate 5, thereby slowing down the rotation speed of the angle plate 5;

[0069] S7, the side of the shaking pipe 1 pushes the anti-slip cone 12, and the anti-slip cone 12 squeezes the compression spring 135 through the sleeve 132, and the compression spring 135 is deformed under pressure, and the restoring elastic force of the compression spring 135 prevents the shaking of the pipe 1;

[0070] S8. The control system starts the deviation correction motor 114. The output shaft of the deviation correction motor 114 drives the driving gear 115 to rotate. The driving gear 115 drives the cylinder seat 9 on the vertical shaft 112 to rotate in the opposite direction through the driven gear 113, so that the upper pressing wheel 10 and the lower pressing wheel 6 rotate in opposite directions, and the friction between the upper pressing wheel 10 and the pipe 1 further hinders the shaking of the pipe 1.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
