Description

Technical Field

[0002] Municipal pipelines include rainwater pipelines, sewage pipelines, water supply pipelines, etc.; after long-term use, the pipelines are prone to blockage, and dredging devices are required for dredging.

[0003] For example, in the patent with the application number: CN202011365781.6, a blocking object grabbing device for municipal pipeline dredging is disclosed, which includes a double-layer base, a steering component, a connection mechanism, a grabbing component, a collection component, and a fixing component. The steering component includes a rotating mechanism and a steering housing. The connection mechanism is arranged on the top of the double-layer base through the steering component. The grabbing component includes a clamping mechanism, an angle adjustment mechanism, a lifting mechanism, and a lifting housing. The collection component includes a collection box and a flipping mechanism. The fixing component includes four support mechanisms. Through the close cooperation of the lifting mechanism, the angle adjustment structure, and the clamping jaw mechanism, the automatic clamping of the blocking object by the grabbing component is realized. The cooperation of the steering component and the connection mechanism enables the grabbing component to clamp the blocking object within the moving range of the device in all directions and at multiple angles, improving the dredging operation efficiency.

[0018] Beneficial effects

[0019] According to the municipal pipeline dredging device of the embodiments of the present invention, compared with traditional dredging equipment, it enables the staff to appropriately adjust the dredging depth by replacing nylon ropes of different lengths, and when the device is used in reverse, it can press on the blockage, making the blockage more flat, facilitating the dredging of blockages in municipal pipelines, and improving the dredging effect of municipal pipelines.

[0020] In addition, since the lifting lug is connected in the threaded hole A and a nylon rope is connected to the lifting lug, it is convenient for the staff to appropriately adjust the dredging depth by replacing nylon ropes of different lengths, which is convenient for use in different municipal pipelines and has strong versatility. Since the solid block is installed outside the sliding block, the two dredging plates are inserted into the blockage under the gravity of the solid block. Also, since the two strong magnets are fixedly installed inside the two positioning blocks and the two strong magnets are in contact with the two dredging plates, the rotation of the two dredging plates is avoided, ensuring that the two dredging plates move vertically downward. Since the six sliding shafts are slidably connected to the solid block, the six spring A are installed outside the six sliding shafts, and the six spring A are located between the solid block and the six retaining rings A. When one or more sliding shafts contact the blockage, the connecting ring moves upward. Also, since the limiting rod is tangent to the supporting block, the rear end of the limiting rod is inserted into the limiting groove, the spring B is installed outside the limiting rod, and the spring B is located between the fixed seat and the retaining ring B. When the connecting ring moves upward, the limiting rod is separated from the limiting groove under the action of the spring B. Since the solid block is slidably connected to the sliding block, the four racks are fixedly installed inside the four mounting brackets, and the four racks are meshed with the four gear A. When the limiting rod is separated from the limiting groove, the solid block quickly moves downward under the action of gravity, causing the two dredging plates to rotate inward simultaneously under the action of the four gear A and the four racks, realizing the automatic clamping of the blockage. At the same time, the two dredging plates are always in close contact with the blockage under the action of the solid block, preventing the blockage from falling off, and facilitating the staff to remove the blockage in the municipal pipeline by pulling the nylon rope.

[0021] In addition, since the guide ring is fixedly installed on the mounting seat, the guide ring is slidably connected to the buffer flat plate, the bending spring A is installed outside the guide ring, and the bending spring B is installed outside the guide ring. When one or more buffer flat plates contact the inner wall of the municipal pipeline during the movement of the device, the corresponding buffer flat plate bends, playing a good buffering role and preventing the device from being damaged due to collision.

[0022] In addition, since the sizes of the threaded holes A and B are the same, when the staff connects the lifting lug to the threaded hole B for use, the direction of the device is opposite during the movement process. At this time, when one or more buffer leveling plates contact the inner wall of the municipal pipeline, the corresponding buffer leveling plates can also bend, which also plays a good buffering role and avoids damage to the device due to collision. When the twelve buffer leveling plates contact the blockage, the twelve buffer leveling plates press on the blockage. Also, since the eight support columns are fixedly installed on the top of the solid block and the eight conical blocks are fixedly installed on the top of the eight support columns, when the eight conical blocks are inserted into the blockage and the nylon rope is pulled upward, the blockage becomes loose under the action of the eight conical blocks. In addition, when used in combination with the twelve buffer leveling plates, the blockage becomes more flat, facilitating the two dredging plates to continue to grab the blockage in the municipal pipeline and improving the dredging effect of the municipal pipeline.

[0048] The limit component 4 includes: a fixed seat 401, a limit rod 402, a retaining ring B 403, and a spring B 404; the fixed seat 401 is fixedly connected to the solid block 201; the limit rod 402 is slidably mounted on the fixed seat 401, and the front end of the limit rod 402 is a hemispherical structure, and the limit rod 402 is tangent to the support block 306, and the rear end of the limit rod 402 is inserted into the limit groove 1011; the retaining ring B 403 is fixedly mounted on the outer wall of the limit rod 402; the spring B 404 is mounted outside the limit rod 402, and the spring B 404 is located between the fixed seat 401 and the retaining ring B 403. Its specific functions are as follows: Since the lifting lug 103 is connected in the threaded hole A 1012, and a nylon rope 6 is connected to the lifting lug 103, it is convenient for the staff to appropriately adjust the dredging depth by replacing nylon ropes 6 of different lengths, which is convenient for use in different municipal pipelines and has strong versatility; Since the solid block 201 is mounted outside the sliding block 101, the two dredging plates 107 are inserted into the blockage under the gravity of the solid block 201. Also, since the two strong magnets 110 are fixedly mounted inside the two positioning blocks 109, and the two strong magnets 110 are in contact with the two dredging plates 107, the two dredging plates 107 are prevented from rotating, ensuring that the two dredging plates 107 move vertically downward; Since the six sliding shafts 301 are slidably connected to the solid block 201, and the six springs A 304 are mounted outside the six sliding shafts 301, and the six springs A 304 are located between the solid block 201 and the six retaining rings A 303, when one or more of the sliding shafts 301 contact the blockage, the connecting ring 302 moves upward. Also, since the limit rod 402 is tangent to the support block 306, the rear end of the limit rod 402 is inserted into the limit groove 1011, the spring B 404 is mounted outside the limit rod 402, and the spring B 404 is located between the fixed seat 401 and the retaining ring B 403, when the connecting ring 302 moves upward, the limit rod 402 is separated from the limit groove 1011 under the action of the spring B 404; Since the solid block 201 is slidably connected to the sliding block 101, and the four racks 205 are fixedly mounted inside the four mounting frames 204, and the four racks 205 are meshed with the four gears A 108, when the limit rod 402 is separated from the limit groove 1011, the solid block 201 quickly moves downward under the action of gravity, causing the two dredging plates 107 to rotate inward simultaneously under the action of the four gears A 108 and the four racks 205, realizing the automatic clamping of the blockage. At the same time, the two dredging plates 107 are always in close contact with the blockage under the action of the solid block 201, preventing the blockage from falling off, and facilitating the staff to remove the blockage in the municipal pipeline by pulling the nylon rope 6.

[0049] In addition, according to an embodiment of the present invention, as Figure 13As shown in the figure, the buffer leveling assembly 5 includes: a mounting base 501, a connecting shaft B 502, and a buffer leveling plate 503; the mounting base 501 is fixedly connected to the solid block 201; the connecting shaft B 502 is rotatably mounted on the mounting base 501; the buffer leveling plate 503 is fixedly mounted on the outer wall of the connecting shaft B 502; the buffer leveling assembly 5 further includes: a guide ring 504, a bending spring A 505, and a bending spring B 506; the guide ring 504 is fixedly mounted on the mounting base 501, and the guide ring 504 is slidably connected to the buffer leveling plate 503; the bending spring A 505 is mounted outside the guide ring 504; the bending spring B 506 is mounted outside the guide ring 504, and the bending spring B 506 is located below the bending spring A 505. Its specific function is that since the guide ring 504 is fixedly mounted on the mounting base 501, and the guide ring 504 is slidably connected to the buffer leveling plate 503, and the bending spring A 505 is mounted outside the guide ring 504, and the bending spring B 506 is mounted outside the guide ring 504, when one or more buffer leveling plates 503 contact the inner wall of the municipal pipeline during the movement of the device, the corresponding buffer leveling plate 503 bends, playing a good buffering role and avoiding damage to the device due to collision.

[0050] In addition, according to an embodiment of the present invention, as Figure 14 shown, since the sizes of the threaded hole A 1012 and the threaded hole B 1041 are the same, when the staff connects the lifting lug 103 to the threaded hole B 1041 for use, the direction of the device is opposite during movement. At this time, when one or more buffer leveling plates 503 contact the inner wall of the municipal pipeline, the corresponding buffer leveling plate 503 can also bend, playing a good buffering role and avoiding damage to the device due to collision; when the twelve buffer leveling plates 503 contact the blockage, the twelve buffer leveling plates 503 press on the blockage. Also, since the eight support columns 202 are fixedly mounted on the top of the solid block 201, and the eight conical blocks 203 are fixedly mounted on the tops of the eight support columns 202, when the eight conical blocks 203 are inserted into the blockage and the nylon rope 6 is pulled upward, the blockage becomes loose under the action of the eight conical blocks 203. Additionally, when used in combination with the twelve buffer leveling plates 503, the blockage becomes flatter, facilitating the two dredging plates 107 to continue grasping the blockage in the municipal pipeline and improving the dredging effect of the municipal pipeline.

[0051] Specific usage method and function of this embodiment: In the present invention, first, the staff selects a suitable nylon rope 6 according to the dredging depth of the pipeline, then winds the nylon rope 6 around the lifting lug 103, and then places this device into the municipal pipeline to be dredged. At this time, the two dredging plates 107 are inserted into the blockage under the gravity of the solid block 201. Also, because the two strong magnets 110 are fixedly installed inside the two positioning blocks 109, and the two strong magnets 110 are in contact with the two dredging plates 107, the rotation of the two dredging plates 107 is thus avoided, ensuring that the two dredging plates 107 move vertically downward; when one sliding shaft 301 or multiple sliding shafts 301 contact the blockage, the connecting ring 302 moves upward. Also, when the connecting ring 302 moves upward, the limiting rod 402 separates from the limiting groove 1011 under the action of the spring B404; when the limiting rod 402 separates from the limiting groove 1011, the solid block 201 rapidly moves downward under the action of gravity, causing the two dredging plates 107 to rotate inward simultaneously under the action of the four gear A 108 and the four racks 205, realizing the automatic clamping of the blockage. At the same time, the two dredging plates 107 are always in close contact with the blockage under the action of the solid block 201, preventing the blockage from falling, facilitating the staff to remove the blockage in the municipal pipeline by pulling the nylon rope 6. When one or more buffer leveling plates 503 contact the inner wall of the municipal pipeline during the movement of this device, the corresponding buffer leveling plate 503 bends, playing a good buffering role and preventing the device from being damaged due to collision;

[0052] When it is necessary to level the blockage in the municipal pipeline, the staff connects the lifting lug 103 to the threaded hole B1041. At this time, the direction of this device is opposite during movement, so that when one or more buffer leveling plates 503 contact the inner wall of the municipal pipeline, the corresponding buffer leveling plate 503 can also bend, also playing a good buffering role and preventing the device from being damaged due to collision; when the twelve buffer leveling plates 503 contact the blockage, the twelve buffer leveling plates 503 exert a pressing force on the blockage. Also, because the eight support columns 202 are fixedly installed on the top of the solid block 201, and the eight tapered blocks 203 are fixedly installed on the top of the eight support columns 202, when the eight tapered blocks 203 are inserted into the blockage and the nylon rope 6 is pulled upward, the blockage becomes loose under the action of the eight tapered blocks 203. Additionally, when used in combination with the twelve buffer leveling plates 503, the blockage becomes flatter, facilitating the two dredging plates 107 to continue grasping the blockage in the municipal pipeline and improving the dredging effect of the municipal pipeline.

[0053] Finally, it should be noted that when the present invention describes the positions of various components and their cooperation relationships, etc., usually one / a pair of components are taken as examples. However, those skilled in the art should understand that such positions, cooperation relationships, etc. are equally applicable to other components / other pairs of components.
