Description

Technical Field

[0001] The invention relates to the technical field of pipe rod cleaning, in particular to a pipe rod cleaning machine with an anti-jamming function. Background Art

[0002] During the cleaning process, the pipe rod cleaning machine uses a high-pressure pump to pressurize water to hundreds or even thousands of pounds per square inch, and then sprays the high-pressure water onto the surface of the pipe rod through a special nozzle. The impact force of the high-pressure water is used to wash away dirt, rust, oil, etc. This method has high cleaning efficiency and causes little damage to the pipe rod surface. It is suitable for cleaning most pipe rods.

[0003] When the pipe rod cleaning machine is working, some of its internal components will be in a specific position or state. When the pipe rod cleaning machine is stopped, these components can be fixed in the current position through the self-locking effect of the motor to prevent them from moving or rotating due to factors such as gravity, external force vibration, etc. For example, prevent the pipe rod being cleaned from sliding due to the equipment being unlocked, avoiding injuring the operator or damaging items around the equipment. When the placement state of the internal pipe rods of the pipe rod cleaning machine is limited by the self-locking effect of the motor, due to reasons such as the unbalanced placement of the internal pipe rods, the motor will be subjected to continuous stress, increasing the risk of damage to the motor on the pipe rod cleaning machine, and when the pipe rod cleaning machine is working, when the internal rotation of the pipe rod cleaning machine When the pipe rod being washed is stuck inside the cleaning machine, the output shaft of the motor is obstructed and the torque is increased, further increasing the risk of damage to the motor on the pipe rod cleaning machine. After the motor is damaged, the locking effect on the rod cleaning machine is lost, making it impossible to lock the rotation and cleaning state of the pipe rod inside the rod cleaning machine. The pipe rod inside the rod cleaning machine shakes and displaces due to the lack of locking under the action of its own gravity or the inertia of rotation. The shaking or displacement of the pipe rod may collide with the internal components of the cleaning machine or even get stuck, making it impossible to discharge the material normally. It needs to be disassembled and separated again later, affecting the normal use of the pipe rod cleaning machine. For this reason, we propose a pipe rod cleaning machine with an anti-stuck function.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1, please refer to Figure 1-Figure 10 , a pipe rod cleaning machine with anti-jamming function shown in the figure includes a chassis 101, a front operating table 102 and a rear operating table 103 are respectively arranged on the front and rear sides of the chassis 101, and a cleaning component 104 for cleaning the pipe rod after placement is arranged inside the chassis 101;

[0038] It should be noted that the cleaning component 104 mainly includes a cleaning nozzle and a delivery pipe, wherein the cleaning component 104 is a conventional operating component in the cleaning process, and its working principle and installation method are prior art, and will not be described in detail here;

[0039] Also includes:

[0040] A support assembly is provided inside the chassis 101 for assisting the placement and support of the pipe rods. The chassis 101 is provided with a feeding and discharging assembly for assisting the feeding and discharging of the pipe rods. A transmission assembly for transmitting the support assembly is provided on the front operating table 102.

[0041] The support assembly includes a first rotating shaft 201 rotatably connected to the chassis 101, the front operating table 102 and the rear operating table 103. A plurality of sets of placement trays 202 are fixed on the first rotating shaft 201. Each set of placement trays 202 is located inside the chassis 101 and is arranged at equal intervals. A plurality of sets of U-shaped grooves 203 for placing pipes and rods are evenly distributed on the outer sides of the placement trays 202. A plurality of sets of mounting racks 204 are fixed inside the chassis 101. The mounting racks 204 are fixed with arc grooves 205 for supporting pipes and rods located at the lower half of the placement trays 202.

[0042] It should be noted here that: during the process of cleaning the pipe rods, the pipe rod cleaning machine assists in the feeding, discharging and rotation cleaning of the pipe rods through the cooperation of the feeding and discharging components and the supporting components, and ensures the straightness of the pipe rods through the supporting effect of the U-shaped grooves 203 on each group of placement plates 202, thereby avoiding the pipe rods from getting stuck during the cleaning process and facilitating the continuous cleaning of the pipe rods. After the cleaning operation is completed and the machine is shut down, the transmission component, the servo drive component, the friction limit component and other components cooperate with each other to disconnect the transmission and avoid the servo motor 501 from being subjected to stress for a long time during the shutdown operation, thereby increasing the probability of damage. The linkage disk 602 and the entire linkage component after the transmission is disconnected can also be self-locked to maintain the status of each group of pipe rods inside the chassis 101 and prevent them from moving or rotating due to factors such as gravity and external force vibration.

[0043] The transmission assembly includes a support frame 401 fixed on the front operating table 102, a transmission shaft 402 is rotatably connected to the support frame 401, a first gear 403 is fixed to the transmission shaft 402, a toothed disc 404 is fixed to the first rotating shaft 201, the first gear 403 and the toothed disc 404 are meshed with each other, a servo drive assembly for driving the transmission shaft 402 is arranged on the front operating table 102, an annular sleeve plate 8 is arranged on the front operating table 102, the annular sleeve plate 8 is connected and fixed to the front operating table 102 through a connecting frame 9, and a friction limit assembly for frictionally limiting the transmission assembly after transmission is arranged on the annular sleeve plate 8;

[0044] It should be noted here that: the linkage disk 602 is rotated by the servo drive component, and the rotation of the linkage disk 602 drives the transmission shaft 402 on the support frame 401 and the first gear 403 on the transmission shaft 402 to rotate. During the rotation of the first gear 403, the first rotating shaft 201 is rotated through the mutual engagement transmission between the first gear 403 and the toothed disk 404.

[0045] Preferably, the servo drive assembly includes a servo motor 501 and a reducer 502 installed on the front operating table 102, the output end of the servo motor 501 is connected and fixed to the input end of the reducer 502, a spline sleeve shaft 503 is fixed to the output end of the reducer 502, the spline sleeve shaft 503 and the transmission shaft 402 are connected and transmitted through a linkage assembly, and the output end of the servo motor 501 is attached with a strain gauge sensor for output torque identification;

[0046] It should be noted here that: the strain gauge sensor is installed at the output end of the servo motor 501 by pasting, and the torque is calculated by measuring the resistance change caused by the torsional deformation of the shaft. The servo motor 501 is provided with a safety drive alarm threshold for identifying and alarming the excessive torque of the servo motor 501. When the servo motor 501 is in use, a safety drive threshold (such as 130% of the rated torque) is set to alarm and disconnect the linkage component, so that when the pipe rod and the inside of the chassis 101 are stuck, so that the rotation of the support component and the output end of the servo motor 501 is blocked and the torque continues to increase, the alarm is identified in time and the transmission is disconnected, thereby reducing the risk of damage to the servo motor 501 on the pipe rod cleaning machine during driving;

[0047] It is worth noting here that the strain gauge sensor and the safety drive alarm threshold on the servo motor 501 are used as prior art in this application, and their working principles and operation connection methods are not described in detail here;

[0048] The linkage assembly includes a spline shaft 601 slidably connected to the spline sleeve shaft 503, a linkage disk 602 is fixed to one end of the transmission shaft 402, a spline hole 603 is opened on the linkage disk 602, the spline sleeve shaft 503, the spline shaft 601, the spline hole 603, the linkage disk 602 and the transmission shaft 402 are concentrically arranged, the linkage disk 602 is located on the inner side of the annular sleeve plate 8, and a moving assembly for moving the spline shaft 601 is arranged on the front operating table 102;

[0049] It should be noted here that: by moving the component, the spline shaft 601 is moved toward the coupling disk 602 and one end of the spline shaft 601 is inserted into the inside of the spline hole 603 to complete the connection between the spline shaft 601 and the coupling disk 602. After the connection is completed, the spline sleeve shaft 503 is rotated through the cooperation between the servo motor 501 and the reducer 502. During the rotation of the spline sleeve shaft 503, the coupling disk 602 is rotated through the connection and transmission action between the spline shaft 601, the spline sleeve shaft 503 and the spline hole 603.

[0050] It is worth noting here that the servo motor 501 and the reducer 502 are conventional operating components for controlling power and torque during the driving process, and are considered as prior art in this application, and will not be described in detail herein.

[0052] It should be noted here that: through transmission, the arc-shaped friction plate 1001, which is subjected to force, moves toward the outside of the linkage disk 602, so that the V-shaped friction block 1002 is inserted into the inside of the V-shaped groove 1003, and the friction generated by the V-shaped groove 1003 and the V-shaped friction block 1002 can self-lock the linkage disk 602 and the entire linkage assembly after the transmission is disconnected, thereby maintaining the status of each group of pipe rods inside the chassis 101 and preventing them from moving or rotating due to factors such as gravity and external force vibration.

[0053] The clamping limit assembly includes a T-shaped limit pin 1201 slidably connected to the arc-shaped friction plate 1001, a spring 1202 is sleeved on the outer side of the T-shaped limit pin 1201, and a plurality of limit grooves 1203 for clamping the ends of the T-shaped limit pin 1201 into the limit position are provided on the outer side of the linkage plate 602;

[0054] It should be noted here that: in the process of the arc-shaped friction plate 1001 moving toward the linkage disk 602, when the T-shaped limit pin 1201 corresponds to the limit groove 1203 on the linkage disk 602, the end of the T-shaped limit pin 1201 is inserted into the interior of the limit groove 1203, which plays a role in limiting the linkage disk 602 and ensuring the locking effect of the linkage disk 602. When the T-shaped limit pin 1201 does not correspond to the limit groove 1203 on the linkage disk 602, the end of the T-shaped limit pin 1201 is against the V-shaped groove 1003 on the outside of the linkage disk 602, thereby increasing the friction locking effect.

During the process of the arc friction plate 1001 being subjected to force, the telescopic guiding effect of the telescopic component causes the arc friction plate 1001 to move toward or away from the outer side of the linkage disk 602.

[0058] It should be noted here that: during the driving process of the moving component, the rack 1502 is driven to move synchronously through the movement of the moving frame 702. During the movement of the rack 1502, the second rotating shaft 1402 and the worm 1403 on the second rotating shaft 1402 are driven to rotate through the mutual engagement transmission between the rack 1502 and the second gear 1501.

[0063] Preferably, the feed and discharge assembly includes a plurality of feed conveyor rollers 301 rotatably connected to the inside of the chassis 101, and a plurality of discharge conveyor rollers 302 are rotatably connected to the inside of the chassis 101, the feed conveyor rollers 301 are located above the discharge conveyor rollers 302, and the feed conveyor rollers 301 and the discharge conveyor rollers 302 are both arranged in a V shape, and a first motor 303 and a second motor 304 are installed on the outside of the chassis 101 to drive the feed conveyor rollers 301 and the discharge conveyor rollers 302 respectively;

[0064] It should be noted here that: the pushed-in pipe rods are supported by multiple groups of feed conveying rollers 301. After the pipe rods to be cleaned are pushed in, the first rotating shaft 201 is rotated, and the rotation of the first rotating shaft 201 drives the groups of placement trays 202 to rotate. During the rotation of the placement trays 202, the pipe rods carried and placed on the groups of feed conveying rollers 301 are inserted into the U-shaped grooves 203 and move inside the chassis 101 with the rotation of the placement trays 202. During the movement of the pipe rods, the cleaning components 104 clean the moving pipe rods. During the high-pressure washing operation, the pipe rods at the lower half of the placement plate 202 are supported by the arc grooves 205 on the mounting frame 204 during the rotation and cleaning process, so as to prevent the pipe rods placed on the U-shaped grooves 203 from sliding down as the placement plate 202 rotates. As the placement plate 202 continues to rotate, when the arc grooves 205 no longer support the pipe rods, the pipe rods fall onto the discharge conveyor rollers 302 by their own gravity, and then the cleaned pipe rods slide outward from the front operating table 102 by the rotation driving action of each group of discharge conveyor rollers 302.

[0065] It should be noted here that a controller is provided on the pipe rod cleaning machine, and the cylinder 704, the first motor 303, the second motor 304, the servo motor 501, the strain gauge sensor and other electrical components are electrically connected to the controller, and each group of driving components is started and stopped by the controller. The controller, the cylinder 704, the first motor 303, the second motor 304, the servo motor 501, the strain gauge sensor and other electrical components are conventional components for controlling the operation of the pipe rod cleaning machine, and are used as prior art in this application and will not be described in detail herein.

[0067] In the process of cleaning the pipe rods, the pipe rods to be cleaned are pushed into the interior of the machine case 101 through the rear operating table 103. During the pushing process, the pushed pipe rods are supported by multiple groups of feeding conveying rollers 301. After the pipe rods to be cleaned are pushed in, the first rotating shaft 201 is rotated, and the rotation of the first rotating shaft 201 drives each group of placement trays 202 to rotate. During the rotation of the placement trays 202, the pipe rods carried and placed on each group of feeding conveying rollers 301 are inserted into the interior of the U-shaped groove 203 and accompanied by the placement trays 202. The U-shaped groove 203 is rotated to move inside the chassis 101. During the movement of the pipe rod, the cleaning component 104 performs high-pressure washing on the pipe rod in the movement process. During the rotation and cleaning process, the arc groove 205 on the mounting frame 204 supports the pipe rod at the lower half of the placement plate 202 to prevent the pipe rod placed on the U-shaped groove 203 from sliding down as the placement plate 202 rotates. As the placement plate 202 continues to rotate, when the arc groove 205 no longer supports the pipe rod, the pipe rod falls onto the discharge conveying roller 302 by its own gravity (see FIG. 2 ). Figure 4 The pipe rods are then driven by the rotation of the discharging conveying rollers 302 to slide out the cleaned pipe rods from the front operating table 102 to complete the cleaning of the pipe rods. During the entire cleaning process, the feeding and discharging components and the supporting components cooperate with each other to assist the feeding and discharging and rotation cleaning of the pipe rods. The straightness of the pipe rods is ensured by the support of the U-shaped grooves 203 on the placement plates 202, which prevents the pipe rods from getting stuck during the cleaning process, and facilitates the continuous cleaning of the pipe rods.

[0068] During the rotation of the first rotating shaft 201, the spline shaft 601 is moved toward the linkage disk 602 by moving the assembly and one end of the spline shaft 601 is inserted into the spline hole 603 to complete the connection between the spline shaft 601 and the linkage disk 602. After the connection is completed, the spline sleeve shaft 503 is rotated by the cooperation between the servo motor 501 and the reducer 502. During the rotation of the spline sleeve shaft 503, the linkage disk 602 is rotated through the connection and transmission effect between the spline shaft 601, the spline sleeve shaft 503 and the spline hole 603. The rotation of the linkage disk 602 drives the transmission shaft 402 on the support frame 401 and the first gear 403 on the transmission shaft 402 to rotate. During the rotation process, the first rotating shaft 201 is rotated by the mutual meshing transmission between the first gear 403 and the toothed disc 404. During the entire transmission driving process, since the strain gauge sensor is installed on the output end of the servo motor 501 by pasting, the torque is calculated by measuring the resistance change caused by the torsional deformation of the shaft. The servo motor 501 is provided with a safety drive alarm threshold for identifying and alarming the excessive torque of the servo motor 501. When the pipe rod and the inside of the chassis 101 are stuck during the rotation cleaning process, the torque of the output end of the support assembly and the servo motor 501 is continuously increased, the alarm is promptly identified and the transmission is disconnected, thereby reducing the risk of damage to the servo motor 501 on the pipe rod cleaning machine during driving;

[0069] When the cleaning operation is completed and the machine needs to be shut down, the driving of the servo motor 501 is stopped and the connection between the spline shaft 601 and the linkage disk 602 is disconnected through the moving assembly. By disconnecting the transmission, the servo motor 501 is prevented from being subjected to stress for a long time during the shutdown operation, which increases the probability of damage. During the driving process, the moving assembly drives the rack 1502 to move synchronously through the movement of the moving frame 702. During the movement of the rack 1502, the second gear 1501 is driven by the mutual meshing transmission between the rack 1502 and the second gear 1501. The shaft 1402 and the worm 1403 on the second rotating shaft 1402 rotate. During the rotation of the worm 1403, the worm 1403 and the worm wheel 1401 are meshed with each other to drive the rotating cover 1301 and the annular plate 1302 to rotate. During the rotation of the annular plate 1302, the interaction between each group of inclined grooves 1303 and each group of transmission pins 1304 and the connection of the connecting plate 1305 respectively causes each group of arc friction plates 1001 to move under force. During the process, the telescopic guide function of the telescopic assembly causes the arc friction plate 1001 to move toward the outside of the linkage disk 602 after being stressed, so that the V-shaped friction block 1002 is inserted into the inside of the V-shaped groove 1003. The friction between the V-shaped groove 1003 and the V-shaped friction block 1002 causes the linkage disk 602 and the entire linkage assembly to be self-locked after the transmission is disconnected, thereby maintaining the status of each group of pipes and rods inside the chassis 101, and preventing them from moving or rotating due to factors such as gravity and external force vibration. During the movement of the linkage disk 602, when the T-shaped limit pin 1201 corresponds to the limit groove 1203 on the linkage disk 602, the end of the T-shaped limit pin 1201 is inserted into the interior of the limit groove 1203, which plays a role in limiting the linkage disk 602 and ensures the locking effect of the linkage disk 602. When the T-shaped limit pin 1201 does not correspond to the limit groove 1203 on the linkage disk 602, the end of the T-shaped limit pin 1201 is against the V-shaped groove 1003 on the outside of the linkage disk 602, thereby increasing the friction locking effect.
