Description

Technical Field

[0001] The present invention relates to the technical field of pipeline dredging, and in particular to a cable pipeline clearing tool. Background Art

[0002] Cable conduit desilting is a crucial task to ensure smooth traffic flow. If a cable conduit becomes clogged with silt, it can cause cable failures and, in turn, traffic disruptions. Therefore, regular desilting of cable conduits is essential. High-pressure cleaning and unclogging heads are commonly used in the prior art. These heads, rotatably connected to a water pipe, can not only spray high-pressure cleaning water to flush and clean the inner wall of the conduit during operation, but also utilize a drill bit at the end to clear and unclog blockages within the conduit. However, existing high-pressure cleaning and unclogging heads lack a support structure. When used, they are placed directly inside the conduit, often contacting the bottom of the conduit. This causes significant wear and tear on the conduit's inner wall as the front end rotates forward. Furthermore, because the high-pressure cleaning and unclogging head is not coaxial with the conduit, blind spots exist during cleaning. This makes it difficult to remove blockages located above the conduit, hindering the subsequent installation of cables within the conduit and reducing construction efficiency. Therefore, a cable conduit desilting tool is urgently needed that can support the high-pressure cleaning and unclogging head, allowing it to be coaxial with the conduit and allowing for stable movement along the conduit's axis. Summary of the Invention

[0003] The purpose of the present invention is to provide a cable pipe blockage clearing tool, which can arrange the high-pressure cleaning and unblocking head coaxially with the pipe, avoiding the high-pressure cleaning and unblocking head from directly contacting the inner wall of the pipe and causing wear, while reducing the cleaning blind area and improving the cleaning effect.

[0004] The present invention adopts the following technical solutions: A cable pipe blockage clearing tool includes a high-pressure cleaning and unclogging head, a support portion is coaxially arranged on the high-pressure cleaning and unclogging head, a plurality of support rods are arranged on the support portion at intervals in the circumferential direction, each of the support rods can be adjusted radially along the support portion, and a roller is movably provided at one end of each support rod located on the outside of the support portion; a driving portion is coaxially rotatably arranged on the support portion, and a driving inclined surface is extended outward at a position opposite to the support rod; a positioning piece for positioning the driving portion is provided on the support portion; during operation, as the driving portion rotates, the driving inclined surface synchronously pushes the support rod out of the support portion.

[0005] Preferably, the support portion is a circular ring structure.

[0006] Preferably, the support portion is provided with an adjustment hole for the support rod to movably pass through, and the support rod is elastically arranged in the adjustment hole by a buffer spring.

[0007] Preferably, a ball is movably provided on one end of the support portion that contacts the driving inclined surface.

[0011] Preferably, a cleaning scraper in contact with the surface of the roller is provided in the groove below the roller.

[0012] Preferably, one end of the roller is rotatably arranged in the groove through a rotating shaft, and a driving rod is eccentrically arranged at the other end. A driving sleeve is provided on the driving rod and arranged along the radial direction of the roller. Guide rods are provided at both ends of the driving sleeve, and the guide rods are slidably connected to the support rods at the corresponding ends.

[0013] Preferably, the cleaning scraper extends from one end in contact with the roller to both sides to form a guide slope.

[0014] Compared with the prior art, the beneficial effects of the present invention are: by coaxially arranging a support part on the outside of the high-pressure cleaning and unclogging head, and movably arranging multiple support rods on the support part, the present invention can utilize the roller on the top of the support rod to contact the inner wall of the pipe to support the high-pressure cleaning and unclogging head, so that the high-pressure cleaning and unclogging head is arranged coaxially with the pipe, thereby reducing the wear caused by its axial movement along the pipe on the inner wall of the pipe. At the same time, the coaxial arrangement of the high-pressure cleaning and unclogging head and the pipe can ensure that it evenly flushes the inner wall of the pipe during rotation cleaning, and utilizes the drill bit at its end to centrally unblock and clean the inside of the pipe, reducing cleaning blind spots and improving the cleaning effect.

[0015] The support rod is axially adjustable on the support part, which can meet the use of pipes with various inner diameters, expanding the scope of application of the present invention. When the support rod needs to be adjusted, it is only necessary to rotate the driving part and use the driving inclined surface to push the support rod out. The operation is simple and fast, and the flexibility is high. At the same time, the present invention can realize the synchronous adjustment of multiple support rods at one time through the rotation of the driving part, ensuring the accuracy and synchronization of the adjustment, and has strong practicality.

DETAILED DESCRIPTION

[0017] The present invention will be described clearly and completely below with reference to the accompanying drawings and embodiments: like Figures 1 to 5 As shown, the cable pipe blockage clearing tool described in the present invention includes a high-pressure cleaning and unclogging head 1. The principle and structure of the high-pressure cleaning and unclogging head 1 can refer to the Lifeng 115 flow high-pressure cleaning and unclogging mouse head. A support part 2 is coaxially arranged on the high-pressure cleaning and unclogging head 1. The support part 2 preferably adopts a circular ring structure, and a mounting hole is provided in the middle for fixing the end of the high-pressure cleaning and unclogging head 1; a plurality of support rods 3 are arranged on the support part 2 at intervals along the circumferential direction, and each support rod 3 can be adjusted radially along the support part 2 to meet the support use of the high-pressure cleaning and unclogging head 1 in pipes of different diameters; each support rod 3 is movably provided with a roller 14 at one end outside the support part 2, and the roller 14 can prevent the high-pressure cleaning When the cleaning and dredging head 1 moves, the friction between the support rod 3 and the inner wall of the pipe ensures the stable movement of the support part 2 along the axial direction of the pipe; a driving part 4 is coaxially arranged on the support part 2, and a through hole is provided on the driving part 4 for the high-pressure cleaning and dredging head 1 to pass through. The through hole is coaxially arranged with the above-mentioned mounting hole and has a diameter larger than the mounting hole, so as to control the driving part 4 from being affected when rotating; the driving part 4 and the support rod 3 are relative to each other and extend outward to form a driving inclined surface 5; a positioning piece for positioning the driving part 4 is provided on the support part 2; during operation, as the driving part 4 rotates, the driving inclined surface 5 synchronously pushes the support rod 3 out of the support part 2 to meet the use of pipes of various diameters. It is easy to operate and highly practical.

[0018] Furthermore, the support portion 2 is provided with an adjustment hole for the support rod 3 to be movably inserted. The support rod 3 is movably inserted into the adjustment hole. A buffer spring 6 is provided on the outer sleeve of the support rod 3. The bottom end of the buffer spring 6 is fixedly connected to the support plate provided on the support rod 3. The top end of the buffer spring 6 is fixedly connected to the top of the adjustment hole. This allows the support rod 3 to be elastically arranged in the adjustment hole, which can not only ensure the stability of the support rod 3 at the bottom position, but also achieve automatic reset of the support rod 3 during the adjustment process. Preferably, a ball 7 is movably provided on the end of the support portion 2 that contacts the driving inclined surface 5 to reduce friction between the support rod 3 and the driving inclined surface 5 when the support rod 3 is adjusted, thereby improving the convenience of the adjustment operation.

[0019] Furthermore, in this embodiment, the positioning member includes a positioning gear 8, which is coaxially arranged on the driving part 4. In this embodiment, the positioning gear 8 is located on the other side of the support part 2 opposite to the driving part 4. An adjustment slot 9 is provided on the support part 2, and an adjustment block 10 is slidably arranged in the adjustment slot 9. A positioning tooth plate 11 is provided on the adjustment block 10. A positioning spring 12 is provided between the adjustment block 10 and the adjustment slot 9. When the positioning tooth plate 11 is in meshing contact with the positioning gear 8, the positioning spring 12 is in a slightly compressed state. When the driving part 4 needs to be rotated, the adjustment block 10 is pulled along the length direction of the adjustment slot 9 to drive the positioning tooth plate 11 to disengage from the positioning gear 8. At this time, the positioning spring 12 is in a further compressed state. The positioning tooth plate 11 is preferably set to a V-shaped structure to ensure the positioning effect.

[0020] Furthermore, a groove 13 is provided on one side of the support rod 3 located outside the support part 2, and the roller 14 is rotatably set in the groove 13. A cleaning scraper 15 in contact with the surface of the roller 14 is provided in the groove 13 below the roller 14, so that the cleaning scraper 15 can be used to clean off the dirt adhering to the roller 14 during its movement, thereby ensuring that the roller 14 moves forward stably along the inner wall of the pipe.

[0021] Preferably, one end of the roller 14 is rotatably arranged in the groove 13 through a rotating shaft, and a driving rod 16 is eccentrically arranged at the other end. A driving sleeve 17 is sleeved on the driving rod 16 and arranged radially along the roller 14. The driving sleeve 17 is a rectangular parallelepiped structure with a through groove opened in the middle along its length direction, and the driving rod 16 is located in the through groove; guide rods 18 are provided at both ends of the driving sleeve 17, and a guide sleeve 19 is provided on the support rod 3 at the corresponding end, and the guide rod 18 is slidably located in the guide sleeve 19; a cleaning brush 20 is provided at the bottom of the driving sleeve 17 through a connecting rod, and the cleaning brush 20 is connected to the groove 13 bottom contact; In addition, the bottom of the cleaning scraper 15 is spaced apart from the bottom of the groove 13, and the side of the cleaning scraper 15 away from the drive sleeve 17 is connected to the side wall of the groove 13, while the side close to the drive sleeve 17 is open, so as to prevent the reciprocating movement of the cleaning brush 20 from being restricted; During operation, as the roller 14 rotates, the drive sleeve 17 will swing horizontally, thereby driving the cleaning brush 20 to clean the bottom of the groove 13, thereby promptly removing dirt accumulated in the groove 13 and preventing the accumulation of dirt in the groove 13 from affecting the rotation of the roller 14. In this embodiment, the cleaning scraper 15 extends from the end in contact with the roller 14 to form a guide slope 21 on both sides, so that the scraped dirt falls smoothly along the guide slope 21, facilitating the cleaning operation of the cleaning brush 20.

[0022] When the present invention is in use, the position of the support rod 3 is first adjusted according to the inner diameter of the pipe. Specifically, during adjustment, the positioning tooth plate 11 is first contacted to engage with the positioning gear 8 for positioning, and then the driving part 4 is rotated to use the driving inclined surface 5 to push the support rod 3 out of the support part 2 by a certain distance to complete the adjustment. After the adjustment is completed, the positioning tooth plate 11 is released and the restoring force of the positioning spring 12 is used to push the positioning tooth plate 11 to engage with the positioning gear 8 to position the driving part 4; after the adjustment is completed, the support part 2 is placed at one end of the pipe and the roller 14 on the support rod 3 is used to contact the inner wall of the pipe to start work. Because under the action of the support part 2, the high-pressure cleaning and dredging head 1 is coaxially arranged with the pipe and is located on the axial position in the pipe, it can effectively improve the clearing effect, reduce the existence of blind spots, and enhance the practicality of the present invention.
