TECHNICAL FIELD

[0001] The utility model relates to condenser pipe stripping machine technical field, especially relates to condenser automatic pipe stripping machine. BACKGROUND

[0002] In the field of industrial refrigeration and heat exchange, the normal operation of the condenser is crucial to the efficiency and stability of the system. During long-term use, the heat exchange tubes inside the condenser may need to be repaired or replaced due to corrosion, fouling, damage, etc. During the repair work of the condenser, pipe stripping is a critical task. In practical applications, condenser pipe stripping repair usually requires the following technologies:

[0003] 1. Precise pipe stripping tools, such as professional cutting tools, removal devices, etc., which can safely separate the heat exchange tubes from the tube sheet of the condenser;

[0004] 2. Efficient pipe removal devices, such as hydraulic pipe pullers or electric pipe pullers, to ensure that the heat exchange tubes can be smoothly pulled out;

[0005] 3. Perfect protective devices, such as protective masks, gloves, protective clothing, etc., to ensure the safety of the operators during the pipe stripping repair process;

[0006] The existing condenser pipe stripping repair device usually cuts or loosens the heat exchange tubes first, and then uses tools to pull out the heat exchange tubes through chiseling, chipping, and punching, etc.

[0007] However, during the implementation of the above technical solutions, it is found that at least the following technical problems exist: The manual pipe stripping method is relatively complex and complicated, which can easily cause a large impact and damage to the tube sheet and surrounding structure of the condenser, thereby affecting the overall structural integrity and sealing of the condenser, involving multiple steps and different tool usage, increasing the time cost and labor intensity of the repair. INVENTION CONTENTS

[0008] (I) Technical problems solved

[0009] To solve the technical problems of the prior art, the utility model provides a condenser automatic pipe stripping machine, which solves the technical problems of the manual pipe stripping method being relatively complex and complicated, easily causing a large impact and damage to the tube sheet and surrounding structure of the condenser, thereby affecting the overall structural integrity and sealing of the condenser, involving multiple steps and different tool usage, and increasing the time cost and labor intensity of the repair.

[0010] (II) Technical solutions

[0011] To achieve the above purposes, the utility model is implemented by the following technical solutions:

[0012] An automatic condenser tube stripper includes a housing. Inside the housing, a slide table is slidably mounted. Support blocks are evenly rotatably mounted on the side of the slide table. A threaded sleeve is slidably mounted inside the slide table, and a top block is fixedly mounted on the side of the threaded sleeve. A first threaded rod is rotatably mounted on the slide table, and a first motor is fixedly mounted at the bottom of the slide table. A second threaded rod is symmetrically rotatably mounted inside the housing, and a second motor is fixedly mounted inside the housing. A control box is fixedly mounted inside the housing. An upper handle with a first button is fixedly mounted on the top of the housing. A side handle with a second button is mounted on the side of the housing. The first motor drives the first threaded rod to rotate via a gear set, and the second motor drives the second threaded rod to rotate via a gear set. The threaded sleeve is threadedly connected to the first threaded rod, and the slide table is threadedly connected to the second threaded rod. The first motor, second motor, and first button are connected to the control box via wires. Second electrode posts are symmetrically mounted at both ends of the housing and connected to the control box via wires. A first electrode post is slidably mounted inside the side handle and connected to the second button via wires. A spring is mounted on the outer wall of the first electrode post.

[0013] Preferably, a protective cover is installed on the side of the outer casing.

[0014] Preferably, both the side grip and the protective cover are connected to the outer shell by bolts.

[0015] (III) Beneficial Effects

[0016] 1. Insert the support block into the cut copper tube, then press the first button. Pressing the first button will send a high-level signal to the control box, which will then control the first motor to drive the first threaded rod to rotate counter-clockwise. Since the first threaded rod is threadedly connected to the threaded sleeve, its counter-clockwise rotation will push the threaded sleeve outwards. As the threaded sleeve slides outwards, the top block at the side end will push the support block to rotate. The four support blocks will then rotate outwards under the push of the top blocks, opening up the inner wall of the copper tube. Then press the second button. The second button will send a high-level signal to the control box via a wire, which will then control the... The shaft of the second motor rotates counterclockwise, which in turn drives two symmetrical second threaded rods to rotate via a gear set (the left second threaded rod rotates counterclockwise, and the right second threaded rod rotates clockwise). Since the slide is threadedly connected to the second threaded rods, the second threaded rods will drive the slide to slide inward. At this time, the side end of the outer casing is against the side end of the condenser. Under the drag of the slide, the copper tube of the condenser will be pulled out through the second threaded rods. The support block clamps the tube from the inside, and the copper tube is pulled out by driving the slide to complete the rapid removal of the condenser, thus reducing maintenance time and labor intensity.

[0017] 2. Unscrew the bolts at both ends of the outer shell to remove the protective cover and side grip. Then, interchange the positions of the side grip and the protective cover. Align the two first electrode posts on the side grip with the two second electrode posts on the side of the outer shell. After alignment, tighten the bolts to fix the side grip and the protective cover. After the side grip is installed, the first electrode posts inside will pop out under the elastic force of the spring, keeping them in close contact with the second electrode posts. This allows the second button to communicate with the control box. The protective cover can protect the unused second electrode posts. This completes the switching of the side grip position, achieving the effect of adjustment according to the user's dominant hand. Attached Figure Description

[0025] This application provides an automatic tube stripping machine for condensers, effectively solving the technical problems of manual tube stripping being cumbersome and complex, easily causing significant impact and damage to the condenser's tube sheet and surrounding structure, thus affecting the overall structural integrity and sealing of the condenser. It also involves multiple steps and different tools, increasing maintenance time and labor intensity. The machine inserts a support block into the cut copper tube, then presses the first button. Pressing the first button sends a high-level signal to the control box, which then controls the first motor to drive the first threaded rod to rotate counterclockwise. Since the first threaded rod is threadedly connected to the threaded sleeve, its counterclockwise rotation pushes the threaded sleeve outwards. During this outward sliding, the top block at the side of the threaded sleeve pushes the support block to rotate. The four support blocks rotate outwards under the push of the top blocks, opening the inner wall of the copper tube. Then, pressing the second button sends a high-level signal to the control box via a wire. The control box then controls the shaft of the second motor to rotate counterclockwise. The second motor then drives two symmetrical second threaded rods (the left second) to rotate via a gear set. The threaded rod rotates counterclockwise, and the second threaded rod on the right rotates clockwise. Since the slide is threadedly connected to the second threaded rod, the second threaded rod will drive the slide to slide inwards. At this time, the side end of the outer casing is against the side end of the condenser. Under the drag of the slide, the copper tube of the condenser will be pulled out via the second threaded rod. The tube is then clamped from the inside by a support block, and the copper tube is pulled out by driving the slide, completing the rapid removal of the condenser. This achieves the effect of reducing maintenance time and labor intensity. Unscrewing the bolts at both ends of the outer casing allows the protective cover and side handle to be removed. Then, the positions of the side grip and the protective cover are interchanged. The two first electrode posts on the side grip are aligned with the two second electrode posts on the side of the outer shell. After alignment, the side grip and the protective cover are fixed by tightening the bolts. After the side grip is installed, the first electrode posts inside will pop out under the elastic force of the spring and keep in close contact with the second electrode posts, so that the second button can communicate with the control box. The protective cover can protect the unused second electrode posts, thus completing the switching of the side grip position and achieving the effect of being adjustable according to the user's dominant hand.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that manual tube stripping is cumbersome and complex, easily causing significant impact and damage to the condenser's tube sheet and surrounding structure, thus affecting the overall structural integrity and sealing of the condenser. It involves multiple steps and the use of different tools, increasing maintenance time costs and labor intensity. The overall approach is as follows:

[0028] To address the problems existing in the prior art, this utility model provides an automatic tube stripping machine for condensers, including a housing 1, a slide table 2 slidably installed inside the housing 1, a support block 5 uniformly rotatably installed on the side end of the slide table 2, a threaded sleeve 3 slidably installed inside the slide table 2, a top block 4 fixedly installed on the side end of the threaded sleeve 3, a first threaded rod 6 rotatably installed on the slide table 2, a first motor 7 fixedly installed at the bottom end of the slide table 2, a second threaded rod 8 symmetrically rotatably installed inside the housing 1, a second motor 9 fixedly installed inside the housing 1, and a control box 11 fixedly installed inside the housing 1.

[0029] An upper handle 12 is fixedly installed on the top of the outer casing 1, and a first button 13 is installed on the upper handle 12. A side handle 14 is installed on the side of the outer casing 1, and a second button 15 is installed on the side handle 14. The first motor 7 drives the first threaded rod 6 to rotate through a gear set, and the second motor 9 drives the second threaded rod 8 to rotate through a gear set. The threaded sleeve 3 is threadedly connected to the first threaded rod 6, and the slide table 2 is threadedly connected to the second threaded rod 8. The first motor 7, the second motor 9, and the first button 13 are connected to the control box 11 through wires.

[0030] The outer casing 1 has two symmetrically mounted second electrode posts 18 at both ends; the second electrode posts 18 are connected to the control box 11 via wires; the first electrode post 16 is slidably mounted inside the side handle 14; the first electrode post 16 is connected to the second button 15 via wires; a spring 17 is mounted on the outer side wall of the first electrode post 16; a protective cover 19 is mounted on the side end of the outer casing 1; the side handle 14 and the protective cover 19 are both connected to the outer casing 1 via bolts 21.

[0031] Working principle:

[0032] First, the control box 11 contains an STM32 microcontroller. During use, the support block 5 is inserted into the cut copper tube. Then, the first button 13 is pressed. Pressing the first button 13 sends a high-level signal to the control box 11, which then controls the first motor 7 to drive the first threaded rod 6 to rotate counterclockwise. Since the first threaded rod 6 is threadedly connected to the threaded sleeve 3, the counterclockwise rotation of the first threaded rod 6 will push the threaded sleeve 3 to slide outwards. During this outward sliding process, the top block 4 at the side end of the threaded sleeve 3 will push the support block 5 to rotate. The four support blocks 5 will rotate outwards under the push of the top block 4, opening up the inner wall of the copper tube. Then, the second button 15 is pressed. The second button 15 sends a high-level signal to the control box 11 through a wire, which then controls the shaft of the second motor 9 to rotate counterclockwise. The second motor 9 will drive the two symmetrical second threaded rods 8 to rotate (the left second threaded rod 8 rotates counterclockwise) through a gear set. As the clockwise rotation causes the second threaded rod 8 on the right to rotate clockwise, the slide 2 and the second threaded rod 8 are threaded together. Therefore, the second threaded rod 8 will drive the slide 2 to slide inward. At this time, the side end of the outer shell 1 is against the side end of the condenser. Under the drag of the slide 2, the copper tube of the condenser will be pulled out through the second threaded rod 8. After the side end of the copper tube is pulled out, first release the first button 13. After the first button 13 is released, it will no longer send a high-level signal to the control box 11. The control box 11 will control the first motor 7 to reverse. The first motor 7 will drive the first threaded rod 6 to rotate clockwise, so that the threaded sleeve 3 drives the top block 4 to reset, so that the support block 5 will no longer jam the inner wall of the copper tube. Then pull the outer shell 1 outward to pull the copper tube out of the outer shell 1. Then release the second button 15. The second button 15 will no longer send a high-level signal to the control box 11. The control box 11 will control the second motor 9 to reverse, so that the second threaded rod 8 drives the slide 2 to reset.

[0033] The second step is to unscrew the bolts 21 at both ends of the outer casing 1 to remove the protective cover 19 and the side handle 14. Then, swap the positions of the side handle 14 and the protective cover 19, aligning the two first electrode posts 16 on the side handle 14 with the two second electrode posts 18 on the side of the outer casing 1. After alignment, tighten the bolts 21 to fix the side handle 14 and the protective cover 19. After the side handle 14 is installed, the first electrode posts 16 inside it will pop outward under the elastic force of the spring 17, keeping them in close contact with the second electrode posts 18, so that the second button 15 can communicate with the control box 11. The protective cover 19 can protect the unused second electrode posts 18.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
