Description

Technical Field

[0001] This utility model relates to the field of underground pipeline repair technology; more specifically, it relates to a turning machine for underground pipeline repair. Background Technology

[0002] Pipeline repair refers to the use of various techniques to restore damaged or leaking pipelines to their normal function. Repair includes two techniques: external corrosion protection layer repair and internal repair. External corrosion protection layer repair involves testing and evaluating the external corrosion protection layer of the pipeline, followed by repair based on the evaluation report. Internal repair is more technically challenging and generally involves a flexible hose inversion lining technique. This involves thoroughly impregnating a fiberglass hose with a waterproof membrane with resin, then using air or water pressure to invert it and tightly adhere it to the inner wall of the old pipeline. After thermosetting, a smooth inner fiberglass lining pipe is formed, thus completing the repair of the old pipeline.

[0003] Currently, existing underground pipeline repair turning machines suffer from several drawbacks during use. Firstly, they often require tools like hose clamps to secure one end of the hose to the conveyor's output. This securing method is time-consuming and labor-intensive. Secondly, some existing machines require vehicles or other transport equipment for movement, resulting in limited flexibility and making them unsuitable for small-scale relocation. Therefore, there is an urgent need for an underground pipeline repair turning machine to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a turning machine for underground pipeline repair to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a turning machine for underground pipeline repair, comprising:

[0006] A conveying structure, comprising a pneumatic conveyor, a support frame, an output port, and a limiting ring;

[0007] A fixing structure, comprising a first fixing ring and a second fixing ring, wherein the surfaces of the first fixing ring and the second fixing ring on opposite sides are both attached to the outer surface of the output port;

[0008] The movable structure includes a movable seat and threaded rods, with four sets of threaded rods, and the upper surface of the movable seat is fixedly connected to the lower surface of the support frame.

[0009] Preferably, the support frame is fixedly connected to the lower surface of the pneumatic conveyor, and a drive motor is installed on one side of the pneumatic conveyor. The output port is fixedly connected to the inside of the pneumatic conveyor, and the limiting ring is fixedly connected to the outer surface of the output port. A fan is installed inside the pneumatic conveyor, and the fan is fixedly connected to the output end of the drive motor. An external power supply can provide power to the drive motor. After the drive motor starts, it can drive the fan inside the pneumatic conveyor to start, and then blow out through the output port.

[0010] Preferably, one end of the first fixing ring is fixedly connected to a connecting post, and a connecting seat is sleeved on the outer surface of the connecting post. One end of the connecting seat is fixedly connected to a second fixing ring. Limiting grooves are formed inside the opposite side of the first fixing ring and the second fixing ring, and the size of the two sets of limiting grooves is adapted to the size of the limiting ring. The connecting seat can rotate on the outer surface of the second fixing ring, and the distance between the first fixing ring and the second fixing ring can be increased when rotating. When the first fixing ring and the second fixing ring are in contact with each other, the two sets of limiting grooves can be engaged with the outer surface of the limiting ring, so that the surfaces of the opposite side of the first fixing ring and the second fixing ring are tightly fitted with the outer surface of the output port.

[0011] Preferably, one end of the second fixing ring is fixedly connected to a first fixing seat, and a hinge seat is fixedly connected to one side surface of the first fixing seat. A connecting plate is hingedly connected to the outer surface of the middle position of the hinge seat. A fixing rod is hingedly connected to the inside of the connecting plate. The other end of the first fixing ring is fixedly connected to a second fixing seat, and a fixing block is fixedly connected to one side surface of the second fixing seat. The position and size of the fixing block are adapted to the position and size of the fixing rod. The connecting plate can rotate on the outer surface of the hinge seat, and when the connecting plate rotates, it can drive the fixing rod to move, so that one end of the fixing rod fits into the inside of the fixing block. At this time, the positions of the first fixing ring and the second fixing ring can be fixed.

[0012] Preferably, a handle is fixedly connected to one end of the upper surface of the movable seat, and universal wheels are fixedly connected to the four corners of the lower surface of the movable seat. The four sets of threaded rods are respectively threaded into the interior of the four corners of the movable seat. Pushing the handle can drive the movable seat to move through the four sets of universal wheels.

[0013] Preferably, the upper ends of the four sets of threaded rods are all fixedly connected to a throttle, and the lower ends of the four sets of threaded rods are all fixedly connected to a support pad. Furthermore, a limit block is threadedly connected to the outer surface of the threaded rod. Rotating the four throttles can drive the four sets of threaded rods to move upward or downward inside the moving seat, and can also drive the four sets of support pads to move synchronously.

[0014] The technical effects and advantages of this utility model are as follows: This utility model involves sleeve one end of the hose on the outer surface of the output port and the limiting ring, then clamping two sets of limiting grooves onto the outer surface of the limiting ring through the hose, and then pulling the connecting plate to drive one end of the fixing rod to engage with the inside of the fixing block. At this time, the fixing structure can be used to fix the hose to the outer surface of the output port. This design can simplify the connection process and make the process of connecting the hose to the output port more time-saving and labor-saving.

[0015] This invention allows the movable base to move via four sets of universal wheels by pushing the handle. After moving the equipment to a suitable position, rotating the four throttles drives the four threaded rods to move downward inside the movable base, simultaneously moving the four support pads to fit against the ground. Then, rotating the four limit blocks causes their upper surfaces to fit against the lower surface of the movable base, thus fixing the position of the four support pads. This design makes the equipment easier to move, thereby improving the flexibility of equipment use to a certain extent. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The underground pipeline repair turning machine involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this utility model provides a turning machine for underground pipeline repair, including: a conveying structure 1, which includes a pneumatic conveyor 11, a support frame 12, an output port 14, and a limiting ring 15. The support frame 12 is fixedly connected to the lower surface of the pneumatic conveyor 11, and a drive motor 13 is installed on one side of the pneumatic conveyor 11. The output port 14 is fixedly connected to the inside of the pneumatic conveyor 11, and the limiting ring 15 is fixedly connected to the outer surface of the output port 14. A fan is installed inside the pneumatic conveyor 11, and the fan is fixedly connected to the output end of the drive motor 13. An external power supply can provide power to the drive motor 13. After the drive motor 13 starts, it can drive the fan inside the pneumatic conveyor 11 to start, and then blow out through the output port 14, thereby turning over the hose sleeved on the outer surface of the output port 14, so that it unfolds inside the pipeline to be repaired and fits against the inner wall of the pipeline. The support frame 12 can improve the stability of the pneumatic conveyor 11 during use.

[0025] The fixing structure 2 includes a first fixing ring 21 and a second fixing ring 24. The surfaces of the first fixing ring 21 and the second fixing ring 24 on opposite sides are both attached to the outer surface of the output port 14. A connecting post 22 is fixedly connected to one end of the first fixing ring 21, and a connecting seat 23 is fitted onto the outer surface of the connecting post 22. The second fixing ring 24 is fixedly connected to one end of the connecting seat 23. Limiting grooves 25 are formed inside the opposite sides of both the first fixing ring 21 and the second fixing ring 24. The dimensions of the two sets of limiting grooves 25 are the same as those of the limiting ring 15. The dimensions are compatible. One end of the second fixing ring 24 is fixedly connected to the first fixing seat 26, and a hinge seat 27 is fixedly connected to one side surface of the first fixing seat 26. A connecting plate 28 is hingedly connected to the outer surface of the middle position of the hinge seat 27, and a fixing rod 29 is hingedly connected to the inside of the connecting plate 28. The other end of the first fixing ring 21 is fixedly connected to the second fixing seat 210, and a fixing block 211 is fixedly connected to one side surface of the second fixing seat 210. The position and size of the fixing block 211 are compatible with the position and size of the fixing rod 29. The seat 23 can rotate on the outer surface of the second fixing ring 24, and the rotation increases the distance between the first fixing ring 21 and the second fixing ring 24. When the first fixing ring 21 and the second fixing ring 24 are in contact with each other, the two sets of limiting grooves 25 can engage with the outer surface of the limiting ring 15, thereby making the surfaces of the first fixing ring 21 and the second fixing ring 24 on opposite sides fit tightly with the outer surface of the output port 14. Furthermore, the engagement between the two sets of limiting grooves 25 and the limiting ring 15 can improve the fit between the outer surface of the hose and the output port 14 and the limiting ring. The sealing performance of the outer surface when it is in contact with the 15 can minimize air leakage at the connection. The connecting plate 28 can rotate on the outer surface of the hinge seat 27, and the connecting plate 28 can drive the fixing rod 29 to move when it rotates, so that one end of the fixing rod 29 is in contact with the inside of the fixing block 211. At this time, the first fixing ring 21 and the second fixing ring 24 can be prevented from rotating, thereby fixing the position of the first fixing ring 21 and the second fixing ring 24. This design allows the fixing structure 2 to quickly and conveniently connect the hose to the output port 14.

[0026] Example 2

[0027] like Figure 5As shown, this embodiment also proposes a movable structure 3, which includes a movable seat 31 and threaded rods 34, with four sets of threaded rods 34. The upper surface of the movable seat 31 is fixedly connected to the lower surface of the support frame 12. A handle 32 is fixedly connected to one end of the upper surface of the movable seat 31, and universal wheels 33 are fixedly connected to the four corners of the lower surface of the movable seat 31. The four sets of threaded rods 34 are respectively threaded into the interior of the four corners of the movable seat 31. A throttle 35 is fixedly connected to the upper end of each of the four sets of threaded rods 34, and a support pad 36 is fixedly connected to the lower end of each of the four sets of threaded rods 34. A limit block 37 is threadedly connected to the outer surface of the threaded rods 34. Pushing the handle 32 can drive the movable seat 31 through the four sets of universal wheels. The wheel 33 moves, and rotating the four sets of throttles 35 can drive the four sets of threaded rods 34 to move up or down inside the moving seat 31, and can also drive the four sets of support pads 36 to move synchronously. The lower surface of each of the four sets of support pads 36 is provided with anti-slip pads. The anti-slip pads are all made of rubber. Since rubber has a high coefficient of friction, it can improve the stability of the support pads 36 when they are in contact with the ground and reduce the possibility of the support pads 36 sliding. Rotating the four sets of limit blocks 37 can make their upper surfaces fit against the lower surface of the moving seat 31, which can prevent the four sets of threaded rods 34 from moving, thereby fixing the position of the four sets of support pads 36 and further improving the stability of the equipment during use.

[0028] Working principle: When using the equipment, first push the handle 32 to move the equipment. After moving the equipment to a suitable position, rotate the four sets of handles 35 to make the four sets of support pads 36 fit against the ground. Then rotate the four sets of limit blocks 37 to make their upper surfaces fit against the lower surface of the moving base 31. At this time, the position of the equipment can be determined.

[0029] Next, one end of the hose is fitted onto the outer surface of the output port 14 and the limiting ring 15. Then, the two sets of limiting grooves 25 are engaged with the outer surface of the limiting ring 15 through the hose. Next, the connecting plate 28 is pulled to engage one end of the fixing rod 29 with the inside of the fixing block 211. This fixing structure 2 fixes the hose to the outer surface of the output port 14. Then, the other end of the hose is inserted into the inside of the pipe to be repaired. Then, the drive motor 13 is powered by an external power source. After the drive motor 13 starts, it drives the fan inside the pneumatic conveyor 11 to start. Then, the hose is blown through the output port 14 to flip. Then, the hose unfolds inside the pipe to be repaired and adheres to the inner wall of the pipe. Finally, it is heated by a hot air device to solidify it, thus completing the repair process. The above is the entire working principle of this utility model.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
