Description

Technical Field

[0001] This utility model relates to the technical field of pipeline repair, and in particular to a material winding and unwinding device for pipeline repair. Background Technology

[0002] UV pipe repair material is a new type of pipe repair material widely used in drainage pipe repair. During pipe repair, the UV pipe repair material needs to be transported to the repair site, then from the ground into the drainage pipe. Air is then injected into the UV pipe repair material, causing it to expand and support itself against the inner wall of the drainage pipe.

[0003] UV pipe repair material is typically wound onto a take-up and unwinding device. After the device is transported to the repair site, the UV pipe repair material is unwound. During unwinding, the tension of the UV pipe repair material's take-up and unwinding device changes, and different materials require different tensions. Conventional take-up and unwinding devices cannot adapt to these tension variations, easily causing wear and tear on the material, rendering the drainage pipe unusable even after repair. Utility Model Content

[0004] In view of this, the present invention aims to provide a material winding and unwinding device for pipeline repair, which can adjust the appropriate tension according to the tension change of the UV pipeline repair material during the unwinding process of the winding and unwinding shaft, so as to reduce the wear on the UV pipeline repair material.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A material winding and unwinding device for pipe repair includes a drive unit, a horizontally arranged winding and unwinding shaft, an adjusting roller with a roller seat, and a tension adjusting device, wherein the adjusting roller is detachably connected to the roller seat.

[0007] The tension adjusting device includes two longitudinally arranged ball screws and a tension sensor disposed on the roller seat. The adjusting roller is disposed between the two ball screws, and the nut of the ball screw is connected to the corresponding roller seat.

[0008] The drive unit drives the take-up and release shaft to rotate, and also drives the ball screw to rotate.

[0009] Furthermore, the drive unit includes a first motor and a second motor, the output shaft of the first motor is connected to the take-up and release shaft, and the output shaft of the second motor is connected to the lead screw of the ball screw.

[0010] Furthermore, it also includes a control unit, and the tension sensor and the second motor are both signal-connected to the control unit.

[0011] Furthermore, one of the roller seats is rotatably connected to a permanent magnet, and the other roller seat is rotatably connected to a rotating column. A connecting cylinder is slidably sleeved at one end of the rotating column, and a snap-fit ​​column is fixedly connected at the other end of the connecting cylinder. The permanent magnet and the snap-fit ​​column are coaxially arranged and have the same outer diameter. One end of the adjusting roller is inserted into the permanent magnet, and the other end is inserted into the snap-fit ​​column.

[0012] Furthermore, a snap-fit ​​strip is fixedly connected to the outer wall of the snap-fit ​​post along the axial direction, and a snap-fit ​​groove adapted to the snap-fit ​​strip is opened on the inner wall of one end of the adjusting roller.

[0013] Furthermore, it also includes a blocking half-ring, the inner diameter of which is the same as the outer diameter of the rotating column. The blocking half-ring is disposed between the rotating column and the roller seat and is snapped into the rotating column.

[0014] Furthermore, a first roller and a second roller are provided on one side of the adjusting roller. The first roller and the second roller have the same structure as the adjusting roller, and the first roller and the second roller are arranged in parallel.

[0015] Furthermore, it also includes a placement box and an operating table. The placement box has an inlet at one end and an outlet at the other end. The operating table is located on the outlet side of the placement box. The take-up and take-down shaft is rotatably located inside the placement box. The drive unit is fixedly located on one side of the placement box. The adjusting roller, the first roller, and the second roller are arranged sequentially on the operating table.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention utilizes a tension sensor to monitor the tension of the UV pipe repair material in real time. Then, the drive unit drives the ball screw to rotate, causing the nut of the ball screw and the roller seat connected to the nut to move up and down. Using the ball screw for control allows for precise control of the up and down movement of the roller seat, thereby fine-tuning the tension of the UV pipe repair material to adapt to changes in the tension of the UV pipe repair material and reduce wear on the UV pipe repair material.

[0018] Secondly, since UV pipe repair materials of different materials are adapted to different tensions, by rotating and connecting a permanent magnet to one roller seat and connecting a rotating column, connecting cylinder, snap-fit ​​column, etc. to another roller seat, it is possible to replace the adjusting roller with a different material according to the different UV pipe repair materials. This allows the material of the adjusting roller to be compatible with the material of the UV pipe repair material, reducing wear on the UV pipe repair material and ensuring that the UV pipe repair material can be repaired completely and without damage when entering the drainage pipe.

[0019] Furthermore, when replacing the adjusting roller, the permanent magnet can initially fix the adjusting roller, and then the replacement can be completed by passing the clip through the other end of the adjusting roller, which improves the replacement efficiency of the adjusting roller.

For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] This embodiment relates to a material winding and unwinding device for pipe repair, one exemplary structure of which is as follows: Figure 1-7 As shown.

[0035] Overall, such as Figure 1-3As shown, the pipe repair material winding and unwinding device includes a drive unit, a transversely arranged winding and unwinding shaft 1, an adjusting roller 3 with a roller seat 2, and a tension adjusting device. The adjusting roller 3 is detachably connected to the roller seat 2. The tension adjusting device includes two longitudinally arranged ball screws 4 and a tension sensor 5 mounted on the roller seat 2. The adjusting roller 3 is positioned between the two ball screws, and the nuts of the ball screws 4 are connected to the corresponding roller seats 2. When the UV pipe repair material on the winding and unwinding shaft 1 is unwound, it rests on the adjusting roller 3. Therefore, by setting the winding and unwinding shaft 1 and the ball screws 4 in different installation directions, the adjusting roller 3 is moved up and down by the nuts of the ball screws 4, thus changing the tension of the UV pipe repair material. When the nuts move the adjusting roller 3 upwards, the tension of the UV pipe repair material increases; when the nuts move the adjusting roller 3 downwards, the tension of the UV pipe repair material decreases.

[0036] The drive unit drives the take-up and release shaft 1 to rotate and also drives the ball screw 4 to rotate. Specifically, the drive unit includes a first motor 6 and a second motor 7. The output shaft of the first motor 6 is connected to the take-up and release shaft 1, and the first motor 6 drives the take-up and release shaft 1 to rotate. The output shaft of the second motor 7 is connected to the ball screw, and the second motor 7 drives the ball screw 4 to rotate. The first motor 6 and the second motor 7 are preferably servo motors.

[0037] In addition, the pipe repair material winding and unwinding device also includes a control unit 8, with the tension sensor 5 and the second motor 7 both connected to the control unit 8. The control unit 8 includes a microcontroller, which receives the tension signal transmitted from the tension sensor 5 and, based on the tension level, starts the second motor 7 according to a pre-set program. This controls the up-and-down movement of the adjusting roller 3 on the roller seat 2, ultimately changing the tension of the UV pipe repair material. Since microcontroller technology and programming technology are relatively mature, and the microcontroller technology and programming technology used in this embodiment are existing technologies, they will not be described in detail here.

[0038] In this embodiment, as Figure 4-5As shown, one roller seat 2 is rotatably connected to a permanent magnet 9, and the other roller seat 2 is rotatably connected to a rotating column 10. A connecting cylinder 11 is slidably sleeved at one end of the rotating column 10, and a locking post 12 is fixedly connected to the other end of the connecting cylinder 11. The permanent magnet 9 and the locking post 12 are coaxially arranged and have the same outer diameter. One end of the adjusting roller 3 is inserted into the permanent magnet 9, and the other end is inserted into the locking post 12. When the adjusting roller 3 rotates, the permanent magnet 9 and the rotating column 10 on the roller seat 2 rotate simultaneously. Therefore, when replacing the adjusting roller 3, it is necessary to slide the connecting cylinder 11 to disengage the locking post 12 from the adjusting roller 3, and then forcefully pull the adjusting roller 3 to disengage the magnetic connection between the adjusting roller 3 and the permanent magnet 9. Among them, the permanent magnet 9 has a large magnetic attraction to the adjusting roller 3. When the adjusting roller 3 rotates, the adjusting roller 3 and the permanent magnet 9 are not easy to disengage. Furthermore, when the locking post 12 is slid into the other end of the adjusting roller 3, the distance between the locking post 12 and the permanent magnet 9 will be less than the length of the adjusting roller 3. Therefore, the adjusting roller 3 will not disengage from the locking post 12 and the permanent magnet 9.

[0039] Preferably, the inner wall of the end where the adjusting roller 3 connects to the permanent magnet 9 is replaced with a material with stronger magnetic attraction. Furthermore, in the above structure, one end of the adjusting roller 3 is fixed to the permanent magnet 9 by magnetic attraction, while the other end is fixed to the locking post 12 by friction.

[0040] In this embodiment, a snap-fit ​​strip 13 is fixedly connected to the outer wall of the snap-fit ​​post 12 along the axial direction, and a snap-fit ​​groove 14 adapted to the snap-fit ​​strip 13 is opened on the inner wall of one end of the adjusting roller 3. When the snap-fit ​​post 12 is inserted into the inner wall of one end of the adjusting roller 3, it is fixed by the snap-fit ​​strip 13 and the snap-fit ​​groove 14. This can increase the friction between the snap-fit ​​strip 13 and the adjusting roller 3, and also ensure that when the adjusting roller 3 rotates, it can drive the snap-fit ​​post 12, the connecting cylinder 11 and the rotating post 10 to rotate in sequence, and the adjusting roller 3 and the snap-fit ​​post 12 are not easy to disengage.

[0041] Preferably, it also includes a blocking half-ring 15, the inner diameter of which is the same as the outer diameter of the rotating column 10. The blocking half-ring 15 is disposed between the rotating column 10 and the roller seat 2 and is snapped into the rotating column 10. When replacing the adjusting roller 3, after the snap-fit ​​post 12 is inserted into the adjusting roller 3, the connecting cylinder 11 moves away from the roller seat 2 on the rotating column 10. Therefore, a moving space appears between the connecting cylinder 11 and the roller seat 2. The blocking half-ring 15 occupies this moving space, preventing the connecting cylinder 11 from sliding towards the roller seat 2. This ensures that the snap-fit ​​strip 13 will not disengage after being inserted into the snap-fit ​​groove 14. Furthermore, it is convenient to install and remove the blocking half-ring 15, ensuring that the replacement of the adjusting roller 3 is simple and quick.

[0042] In this embodiment, as Figure 6-7As shown, a first roller 16 and a second roller 17 are provided on one side of the adjusting roller 3. The first roller 16 and the second roller 17 have the same structure as the adjusting roller 3, and the first roller 16 and the second roller 17 are arranged parallel to each other. The first roller 16 and the second roller 17 are arranged sequentially in the UV pipe repair material conveying direction. The UV pipe repair material passes sequentially above the adjusting roller 3, below the first roller 16, and above the second roller 17. The first roller 16 and the second roller 17 ensure that the UV pipe repair material can be horizontally conveyed out of the operating table 19.

[0043] Furthermore, this embodiment also includes a placement box 18 and an operating table 19, which are fixedly connected. One end of the placement box 18 has an inlet 20, and the other end has an outlet 21. The operating table 19 is located on one side of the outlet 21 of the placement box 18. The take-up and undo shaft 1 is rotatably located inside the placement box 18, and the drive unit is fixedly located on one side of the placement box 18. The adjusting roller 3, the first roller 16, and the second roller 17 are arranged sequentially on the operating table 19. Since UV pipe repair materials are not always wound onto a reel after production, an inlet 20 is provided on the placement box 18. The UV pipe repair material is passed through the inlet 20 and wound onto the take-up and undo shaft 1. The first motor 6 drives the take-up and undo shaft 1 to rotate, winding the UV pipe repair material onto the take-up and undo shaft 1. The placement box 18 and the operating table 19 are generally placed on a transport vehicle. When the drainage pipe needs repair, the placement box 18 and the operating table 19 are transported to the repair site by the transport vehicle, and then the pipe repair material is transported by the take-up and undo shaft 1.

[0044] The working process of this embodiment is as follows:

[0045] The placement box 18 and the operating table 19 are transported to the repair site by a transport vehicle. The end of the UV pipe repair material on the take-up and unwrap shaft 1 in the placement box 18 is passed through the outlet 21 and then sequentially passed above the adjusting roller, below the first roller 16, and above the second roller 17, so that the UV pipe repair material is output horizontally. The UV pipe repair material is then transported into the drainage pipe by other equipment or manually. While the UV pipe repair material is being continuously transported in the drainage pipe, the drive unit is started, and the first motor 6 drives the take-up and unwrap shaft 1 to rotate and continuously unwind until the UV pipe repair material is transported.

[0046] During the unwinding process, the tension sensor 5 monitors the tension change of the UV pipe repair material in real time. When the tension change is too large, the control unit 8 receives the signal from the tension sensor 5 and controls the second motor 7 to rotate, so that the nut of the ball screw 4 drives the roller seat 2 to move up and down to change the tension of the UV pipe repair material.

[0047] When replacing the adjusting roller 3, first remove the blocking half-ring 15 and slide the connecting cylinder 11 towards the roller seat 2, causing the locking strip 13 on the locking post 12 to disengage from the locking groove 14 on the inner wall of the adjusting roller 3. Then, pull the adjusting roller 3 forcefully to disengage the other end of the adjusting roller 3 from the permanent magnet 9, thereby quickly removing the adjusting roller 3. The operation process is the reverse of the above when installing the adjusting roller 3. The replacement methods for the first roller 16 and the second roller 17 are the same as described above.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
