Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipe repair, in particular to a drainage pipe winding repair device. Background Art

[0002] A sewer pipe is a piping system used to collect and transport liquid waste such as domestic sewage, industrial wastewater, and rainwater. It is an important part of urban infrastructure and is responsible for transporting various wastewaters from their sources to sewage treatment plants or discharging them to appropriate locations.

[0003] The drainage pipes on the market generally use PVC pipes. The advantage of PVC pipes is that they are low cost and suitable for drainage systems with less bending and vibration. However, before PVC pipes are put into use, and after long-term use, cracks will inevitably appear on the surface of PVC pipes, causing water in the pipe to splash out through the cracks. Therefore, fiber tapes need to be wrapped around the cracks in the pipes. In order to evenly wrap the fiber tape around the outside of the drainage pipe, special equipment is usually used. This equipment is usually called a "pipe winding machine" or "fiber tape winding machine". The winding head is the core part of the equipment, which is responsible for applying the fiber tape to the pipe. The winding head can adjust the winding speed and tension to ensure that the fiber tape is evenly laid; the conveying system includes a tape feeding device and a guide device, which is used to transport the fiber tape from the reel to the winding head and guide the fiber tape to be evenly distributed along the outside of the pipe; the control system is usually an electronic control panel that allows the operator to adjust parameters such as winding speed, tension, and number of winding layers.

[0004] However, when the pipe winding machine is wrapping the fiber tape around the pipe, the winding head of the winding machine may not set the force properly when tightening the fiber tape, resulting in the force of tightening the fiber tape exceeding the overall pressure resistance of the pipe. Since the pipe is generally made of soft PVC, this will cause the fiber tape to be too tight, which may easily cause local depressions in the PVC pipe, making it difficult to push the depressed part of the PVC pipe back outward and restore it. In view of this, a drainage pipe winding and repair device is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a drainage pipe winding repair device.

The outside of the drain pipe can be wrapped with a fiber belt. When dents appear on the surface of the drain pipe due to tension, the remote-controlled vehicle drives the repair plate to expand and repair the inner wall of the drain pipe, so as to avoid the fiber belt being wrapped around the outside of the drain pipe and tightened, causing the drain pipe to sag inward.

[0008] As a further description of the above technical solution: there is a gap between the inside of the hollow ball and the solid ball, and the width of the gap matches the thickness of the limiting plate. There are four limiting plates, and the limiting plates are distributed in the upper, lower, front and rear positions between the inner wall of the hollow ball and the surface of the solid ball, so that the limiting plates can drive the sliding rod to slide between the inner wall of the hollow ball and the surface of the solid ball.

[0009] As a further description of the above technical solution: the number of the sliding rods is the same as the number of the limit plates, the surface of the hollow ball is provided with four sliding grooves from left to right, and the width of the sliding grooves on the surface of the hollow ball matches the cross-sectional diameter of the sliding rods, and the position of the sliding grooves on the surface of the hollow ball matches the position of the sliding rods. The hollow ball can be moved left and right to allow the sliding rods to drive the four groups of support rods to expand outward or retract inward at the same time by pulling and pushing.

[0010] As a further description of the above technical solution: a circular hole is opened around the middle of the first hollow tube, and the diameter of the circular hole matches the cross-sectional diameter of the support rod. A rotating shaft is provided between the inner top end of the support rod and the outer top end of the sliding rod, for the support rod to pass through the inside of the first hollow tube to connect to the inner side of the repair plate.

[0011] As a further description of the above technical solution: the inner and outer sides of the repair plate are both curved, and the outer side of the repair plate is sprayed with an epoxy coating, which can ensure that the outer side of the repair plate is in close contact with the inner wall of the drainage pipe and reduce the friction generated by the contact during sliding.

[0012] As a further description of the above technical solution: a storage bin is fixedly connected to the rear portion of the interior of the second hollow cylinder, a feed pipe is fixedly connected to the lower portion of the front end surface of the storage bin, a feed pump is fixedly connected to the end of the feed pipe away from the storage bin, the bottom of the feed pump is fixedly connected to the lower portion of the interior of the second hollow cylinder, a discharge pipe is fixedly connected to the output end of the feed pump, a spray pipe is fixedly connected to the end of the discharge pipe away from the feed pump, and the upper portion of the interior of the second hollow cylinder is fixedly connected to the lower portion of the spray pipe, which can repair cracks in the inner wall of the drainage pipe by spraying and smoothing with the rotating repair plate, thereby reducing the difficulty of repairing cracks in the inner wall of the drainage pipe that are entangled by the fiber belt.

[0013] As a further description of the above technical solution: epoxy resin glue is stored inside the storage bin, and the end of the feed pipe away from the storage bin is fixed at the input end of the feed pump, which can repair cracks on the inner wall of the drainage pipe without dead angles, thereby improving the efficiency of repairing cracks in the drainage pipe to a certain extent.

[0014] The utility model has the following beneficial effects:

[0015] The drainage pipe winding and repair device designed by the present invention uses a remote-controlled vehicle and a repair plate to enable the device to wrap a fiber belt around the outside of the drainage pipe. When a dent appears on the surface of the drainage pipe due to tension, the remote-controlled vehicle drives the repair plate to expand and repair the inner wall of the drainage pipe, thereby preventing the fiber belt from winding around the outside of the drainage pipe and tensioning it, causing the drainage pipe to sag inward. At the same time, an electric telescopic rod and a hollow ball for the repair plate to expand or retract outward are provided inside and on the rear end face of the first hollow tube. The electric telescopic rod drives the hollow ball to slide back and forth in the first hollow tube, and cooperates with the sliding rod restricted inside the hollow ball to allow the support rod to drive the repair plate to move on the surface of the first hollow tube. The position of the repair plate can be adjusted according to drainage pipes of different models and inner diameters. It has a wide range of versatility and can also allow the repair plate to fit tightly against the inner wall of the drainage pipe, thereby improving the repair effect to a certain extent.

[0016] The drainage pipe winding repair device designed by the present invention can spray material to repair cracks on the inner wall of the drainage pipe by designing a material pump and a spray pipe, and smooth it with the rotating repair plate, which can reduce the difficulty of repairing cracks on the inner wall of the drainage pipe wrapped by the fiber belt. The second hollow cylinder is also driven to rotate by the motor, and can repair cracks on the inner wall of the drainage pipe without dead angles, thereby improving the efficiency of repairing drainage pipe cracks to a certain extent.

The outside of the drain pipe can be wrapped with a fiber belt. When the surface of the drain pipe is dented due to tension, the remote control vehicle 1 drives the repair plate 8 to expand and repair the inner wall of the drain pipe to avoid the fiber belt being wrapped around the outside of the drain pipe and tightened, causing the drain pipe to sag inward.

[0024] As a further implementation plan of the above technical solution: there is a gap between the inside of the hollow ball 11 and the solid ball 13, and the width of the gap matches the thickness of the limiting plate 14. There are four limiting plates 14, and the limiting plates 14 are distributed in the upper, lower, front and rear positions between the inner wall of the hollow ball 11 and the surface of the solid ball 13, so that the limiting plates 14 can drive the sliding rod 12 to slide between the inner wall of the hollow ball 11 and the surface of the solid ball 13.

[0025] As a further implementation plan of the above technical solution: the number of sliding rods 12 is the same as the number of limiting plates 14, and four sliding grooves from left to right are opened on the surface of the hollow ball 11, and the width of the sliding groove on the surface of the hollow ball 11 matches the cross-sectional diameter of the sliding rod 12, and the position of the sliding groove on the surface of the hollow ball 11 matches the position of the sliding rod 12. The hollow ball can be moved left and right to allow the sliding rod 12 to drive the four groups of support rods 7 to expand outward or retract inward at the same time by pulling and pushing.

[0026] As a further implementation plan of the above technical solution: a circular hole is opened around the middle of the first hollow tube 5, and the diameter of the circular hole matches the cross-sectional diameter of the support rod 7. A rotating shaft is provided between the inner top end of the support rod 7 and the outer top end of the sliding rod 12, for the support rod 7 to pass through the inside of the first hollow tube 5 to connect to the inner side of the repair plate 8.

[0027] As a further implementation plan of the above technical solution: the inner and outer sides of the repair plate 8 are both curved, and the outer side of the repair plate 8 is sprayed with an epoxy coating, which can ensure that the outer side of the repair plate 8 is in close contact with the inner wall of the drainage pipe and reduce the friction generated by the contact during sliding.

[0028] As a further implementation plan of the above technical solution: a storage bin 15 is welded at the rear of the interior of the second hollow cylinder 9, and a feed pipe 16 is welded below the front end of the storage bin 15.

[0030] Working principle:

[0031] When using the utility model, according to the problem of the drainage pipe, it is determined whether the repair plate 8 or the spraying pipe 10 enters the pipe first. If the drainage pipe is deformed by being squeezed by the fiber belt, the repair plate 8 can be allowed to enter the pipe first, and the remote control car 1 is placed in the drainage pipe. The remote control car 1 is started. After the remote control car 1 is remotely controlled to the deformed part, the electric telescopic rod 6 on the rear end face of the first hollow cylinder 5 is started. The electric telescopic rod 6 drives the hollow ball 11 from the rear of the first hollow cylinder 5 to move toward the middle of the first hollow cylinder 5. The solid ball 13 inside the hollow ball 11 limits the sliding of the limiting piece 14. At this time, the sliding rod 12 on the outer end face of the limiting piece 14 drives the support rod 7 to slide outward under the restriction of the hollow ball. At this time, when the sliding rod 12 changes its angle, the support rod 7 is affected by the angle change of the sliding rod 12, driving the repair plate 8 to expand outward until the repair plate 8 contacts the inner wall of the drainage pipe and stops, and then opens near the first A motor 4 in a fixed ring 3 at a hollow cylinder 5 drives the first hollow cylinder 5 to rotate, and the rotating repair plate 8 repairs the sunken area inside the pipe by positioning and rotating; if there is a crack on the inner wall of the drainage pipe, the spray pipe 10 is allowed to enter the pipe first. After the remote control vehicle 1 drives the spray pipe 10 to move to the target area, the second hollow cylinder 9 is driven to rotate by starting the motor 4, so that the position of the spray pipe 10 outside the second hollow cylinder 9 is adjusted, and the material pump 17 is turned on after the adjustment is completed. The material pump 17 extracts the epoxy resin glue inside the storage bin 15 through the feed pipe 16, and then injects it into the spray pipe 10 through the discharge pipe 18, so that the epoxy resin glue is sprayed toward the crack through the spray pipe 10, and cooperates with the repair plate 8 rotating outside the first hollow cylinder 5 at the other end of the second hollow cylinder 9 to smooth the epoxy resin glue, and repair the cracks on the inner wall of the drainage pipe without dead angles, thereby improving the efficiency of repairing drainage pipe cracks to a certain extent.
