Description

Technical Field

[0001] This utility model relates to the field of municipal drainage pipe network maintenance technology, specifically to a cleaning device for trenchless pipe repair. Background Technology

[0002] In the field of municipal drainage network maintenance, trenchless pipeline repair technology has been widely used due to its minimal impact on surface traffic and the surrounding environment. Before repair work, the inside of the pipeline must be thoroughly cleaned to ensure the quality of the repair.

[0003] Currently, the industry commonly uses high-pressure water jet flushing to clean debris inside pipes, which is effective at removing mud, sand, and small debris. However, when larger stones or other hard debris are present in the pipes, high-pressure water jets are insufficient to remove them effectively. This necessitates manual entry into the pipes or collection along the pipe inspection route, followed by high-pressure cleaning. This approach not only prolongs the overall cleaning time and reduces operational efficiency but also increases the labor intensity of personnel due to manual intervention.

[0004] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a cleaning device for trenchless pipeline repair that can automatically collect stones and other debris in drainage pipes.

[0007] Both the cleaning box and the storage box have several pairs of walking wheels that are symmetrically and obliquely arranged on both sides of the bottom, which cooperate with the inner walls of the pipe. The cleaning box also has hooks that cooperate with the traction rope on both sides.

[0008] The cleaning box has a rectangular structure and is open on both the front and back sides. The collection mechanism includes a first rotating rod that is rotatably connected between the two sides below the cleaning box. A connecting block is sleeved on the outside of the first rotating rod. Connecting plates facing forward are fixedly connected to both ends of the connecting block. An arc-shaped collection hopper is fixedly connected between the two connecting plates.

[0009] The first rotating rod has a first gear coaxially sleeved at both ends, and the front two sides of the cleaning box are symmetrically and vertically slidably connected with a first rack, and the first gear meshes with the first rack located on the same side;

[0010] The first rack is fixedly connected to the telescopic end of the first electric cylinder, and the fixed part of the first electric cylinder is fixedly connected to the front side wall of the cleaning box.

[0011] The front bottom of both connecting plates is rotatably connected to a second gear, and a second rotating rod is coaxially fixed between the two second gears. The second rotating rod is sleeved on the inner wall of one side of the scraper, and a rubber plate with elasticity is provided on the side of the scraper away from the second rotating rod.

[0012] A second electric hydraulic cylinder is provided on the top of the connecting plate. The telescopic end of the second electric hydraulic cylinder is fixedly connected to the end of the second rack. The second rack is slidably connected to the top of the connecting plate and meshes with the second gear located on the same side.

[0013] The storage box has a rectangular structure and is open on the side facing the cleaning box. Insert plates are provided on the front two sides and the bottom side of the storage box. Slots that can be inserted and matched with the insert plates are provided on the rear two sides and the bottom side of the cleaning box. Several fixing bolts are fixedly connected between the insert plates and the cleaning box.

[0014] The side of the lifting plate away from the cleaning box rotates with the inner wall of the storage box.

[0015] The lifting plate is fixedly connected to two ends near the cleaning box, with lifting rods extending to the outside of the cleaning box. The cleaning box has sliding grooves on both sides that slide with the lifting rods.

[0016] The lifting component includes a first pull rope with one end fixedly connected to the lifting rod. The end of the first pull rope away from the lifting rod passes around the first rope pulley and faces the cleaning box, and is fixedly connected to a U-shaped first locking block. A pulling block is fixedly connected to the top of the first rack. A pulling rod facing outward is fixedly connected to the pulling block. The pulling rod is fixedly connected to one end of a second pull rope. The end of the second pull rope away from the pulling rod passes around the second rope pulley and faces the storage box, and is fixedly connected to a plate-shaped second locking block. A connecting bolt nut is fixedly connected between the first locking block and the second locking block.

[0017] The cleaning box is equipped with a mounting frame on top, and wireless cameras and supplementary lights are installed on both the front and rear sides of the mounting frame.

[0018] The side walls of the cleaning box are respectively equipped with a local control terminal and a battery. The local control terminal is electrically connected to the collection mechanism, the conveyor belt, and the driver of the supplementary light. The local control terminal and the wireless camera are wirelessly connected to a remote display control terminal.

[0019] In practical use, the cleaning box is placed at the inlet of the pipe. Then, the storage box is fixed to the cleaning box by inserting a plate into the slot and using fixing bolts. The first and second locking blocks are fixedly connected by connecting bolt nuts. The traction rope is fixedly connected to the hook. The box is then moved to the outlet side of the pipe and simultaneously pulled horizontally from both sides manually or by a winch. The wheels on both sides are located on either side of the pipe, preventing obstruction by stones or other hard debris at the bottom of the pipe. During movement, a wireless camera observes the presence of stones at the bottom of the pipe. Upon finding stones, the scraper is positioned above and behind the stones to stop traction. Then, the second electric cylinder is activated, driving the second rack forward to rotate the second gear. The second gears on both sides drive the scrapers to flip inward, scraping stones into the collection hopper. Once the collection hopper has collected enough stones, the first electric cylinder drives the first rack, which in turn rotates the first gear, simultaneously driving the collection hopper to flip the collected stones onto the conveyor belt. Then, the conveyor motor starts, transferring the stones into the storage box at the rear. Simultaneously, as the collection hopper flips, it pulls the second rope via a traction block. The second rope pulls the first rope, which in turn pulls the lifting rod upward, raising the front of the lifting plate at a certain angle. This allows the previously collected stones to slide towards the rear of the storage box at an angle, preventing stones from accumulating at the front and hindering smooth collection. A limiting sleeve restricts the direction of the first and second ropes. The device collects stones as it moves, completing the collection at the outlet. The storage box and cleaning box are then separated, and the storage box can be emptied separately. The operation can be carried out remotely with the aid of images provided by a wireless camera and supplementary lighting. When the distribution of stones inside the pipe is complex, operators can enter the pipe to collect the stones through the local control terminal.

[0020] The beneficial effects of this utility model are: it improves the efficiency of cleaning the inside of the pipeline before trenchless pipeline repair and reduces the labor intensity of construction workers. Attached Figure Description

[0033] Two connecting plates 203 are rotatably connected to their front bottom sides with second gears 208. A second rotating rod is coaxially and fixedly connected between the two second gears 208. The second rotating rod is sleeved on the inner wall of one side of the scraper 210. A flexible rubber plate 211 is provided on the side of the scraper 210 away from the second rotating rod 209. A second electric cylinder 212 is provided at the top of the connecting plate 203. The telescopic end of the second electric cylinder 212 is fixedly connected to the end of the second rack 213. The second rack 213 is slidably connected to the top of the connecting plate 203 and meshes with the second gear 208 located on the same side. The rubber plate at the bottom of the scraper can scrape tightly against the bottom of the pipe, ensuring effective scraping while being wear-resistant and easy to replace. The rubber plate can be connected to the scraper with bolts.

[0034] The storage box 4 has a rectangular structure and is open on the side facing the cleaning box 1. Insert plates 401 are provided on the front two sides and bottom of the storage box 4. Slots 102 are provided on the rear two sides and bottom of the cleaning box 1 to engage with the insert plates 401. Several fixing bolts 402 are fixedly connected between the insert plates 401 and the cleaning box 1. The side of the lifting plate 5 away from the cleaning box 1 is rotatably connected to the inner wall of the storage box 4. Lifting rods 501 extending to the outside of the cleaning box 1 are fixedly connected to both ends of the lifting plate 5 near the cleaning box 1. Sliding grooves 103 are provided on both sides of the cleaning box 1 to slide with the lifting rods 501. By separating the storage box and the cleaning box, the storage box has a simple structure and single function, facilitating future maintenance and replacement.

[0035] The lifting component 6 includes a first pull rope 601 with one end fixedly connected to the lifting rod 501. The end of the first pull rope 601 away from the lifting rod 501 passes around the first rope pulley 602 toward the cleaning box 1 and is fixedly connected to a U-shaped first locking block 603. A pulling block 604 is fixedly connected to the top of the first rack 206. A pulling rod 605 facing outward is fixedly connected to the pulling block 604. The pulling rod 605 is fixedly connected to one end of the second pull rope 606. The end of the second pull rope 606 away from the pulling rod 605 passes around the second rope pulley 607 toward the storage box 4 and is fixedly connected to a plate-shaped second locking block 608. A connecting bolt nut 609 is fixedly connected between the first locking block 603 and the second locking block 608.

[0036] In actual use: Place the cleaning box 1 into the inlet of one side of the pipe 7, then insert the insert plate 401 into the slot 102 and fix the storage box 4 to the cleaning box with the fixing bolt 402. Fix the first locking block 603 and the second locking block 608 with the connecting bolt nut 609. Fix the traction rope to the hook 101. Then send it to the outlet side of the pipe 7. Move it horizontally on both sides simultaneously by manual labor or a winch. The two side wheels 8 are located on both sides of the pipe, so they will not be obstructed by hard objects such as stones left at the bottom of the pipe. During the movement, the wireless camera 10 observes the situation of stones left at the bottom of the pipe 7. After a stone is found, place the scraper 210 above and behind the stone to stop traction. Then start the second electric cylinder 212 to drive the second rack 213 to move forward, thereby rotating the second gear 208. The second gears 208 on both sides drive the scraper. 210 flips inward, and scraper 210 scrapes the stones into collection hopper 204. After collection hopper 204 has collected enough stones, the first electric cylinder 207 is activated to drive the first rack 206, which in turn drives the first gear 205 to rotate. At the same time, the collection hopper 204 flips the collected stones onto the conveyor belt 3. Then, the conveyor motor 301 is activated to transfer the stones into the storage box 4 at the rear. At the same time, as the collection hopper 204 flips, it pulls the second pull rope 606 through the pull block 604. The second pull rope 606 pulls the first pull rope 601, which in turn pulls the lifting rod 501 upward. This raises the front of the lifting plate 5 at a certain angle, allowing the previously collected stones to slide towards the rear of the storage box 4 at an inclined angle. This prevents the stones from accumulating at the front and affecting smooth collection. The limiting sleeve 610 restricts the direction of the first pull rope 601 and the second pull rope 606. The device collects stones as it moves, and once it reaches the outlet, the stone collection is complete. Storage box 4 is then separated from cleaning box 1, and storage box 4 can be emptied separately. The operation can be performed remotely via a wireless camera with image assistance, and supplementary lighting 11 provides reliable illumination. In cases where the stone distribution inside pipe 7 is complex, operators can enter the pipe to collect the stones via local control terminal 12.
