Description

Technical Field

[0001] This utility model belongs to the field of municipal environmental construction technology, and in particular relates to a fixing device for the repair of municipal sewage pipe networks. Background Technology

[0002] Drainage pipe networks are the foundation of urban safety and prosperity. Their proper functioning is related to the city's environmental conditions and sanitation, as well as road traffic safety. Drainage pipe network repair can be carried out in two ways: excavation and trenchless construction. The biggest advantage of trenchless construction is that it involves very little excavation during construction, reducing damage and adverse effects on traffic, the environment, and the foundations of surrounding buildings, and minimizing disruption to residents' daily lives. It has better social and economic benefits. Under comparable conditions, the overall cost of trenchless pipeline repair is lower than that of excavation construction, and this difference is more pronounced with larger pipe diameters and greater burial depths. In most cases, especially in bustling urban areas or areas where pipelines are buried deep, trenchless construction is an excellent alternative to excavation construction.

[0003] Existing fixing devices are not convenient for accurately positioning pipelines, which leads to a series of problems during the repair process, such as loose connections and positional deviations. This not only prolongs the maintenance cycle and increases maintenance costs, but may also affect the safety and operational efficiency of the entire pipeline network system in severe cases. Summary of the Invention

[0004] The purpose of this utility model is to provide a fixing device for municipal sewage pipe network repair. By setting a sewage pipe fixing mechanism, the sewage pipe is inserted into the circular hole surrounded by four fixing arms. Turning the crank handle causes the rotating shaft to rotate, allowing gear one to rotate on the outer wall of the support base. Simultaneously, gear one drives gear two to rotate on the support base, causing four fixing posts two on the outer wall of gear two to move along an arc. At the same time, four rotating frames rotate along an arc, causing the ends of the four fixing arms furthest from fixing posts one to rotate around fixing posts one within a certain angle. Simultaneously, as they approach the center of gear two, the fixing arms gradually tighten until all four fixing arms contact the outer wall of the sewage pipe, fixing the pipe at the center of the support base. This avoids problems such as misalignment during pipe repair, avoids the instability and difficulty in precise positioning caused by manually holding the sewage pipe, and solves the problem of reduced efficiency in pipe repair work.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fixing device for repairing municipal sewage pipe networks, including a base plate and a lifting platform. The base plate is provided with a sewage pipe fixing mechanism and a lifting mechanism.

[0007] The sewage pipe fixing mechanism includes two support seats fixedly connected to the lifting platform. A crank handle is rotatably connected to the side of each support seat that is close to it. A rotating shaft is fixedly connected to the outer wall of each crank handle, passing through the two support seats. The rotating shaft is rotatably connected to the support seats. A gear is fixedly connected to the outer wall of each rotating shaft away from the crank handle. A gear is rotatably connected to the side of each support seat that is far from it. The gear meshes with the gear. Four fixing columns are fixedly connected to the outer wall of each support seat. A fixing arm is rotatably connected to the outer wall of each of the four fixing columns. Four fixing columns are fixedly connected to the outer wall of each gear. A rotating frame is rotatably connected to the outer wall of each of the four fixing columns. The fixing arm is slidably connected to the inner wall of the rotating frame.

[0008] Furthermore, the lifting platform is fixedly connected to two fixing blocks 2, and the inner walls of the two fixing blocks 2 are rotatably connected to brackets 1.

[0009] Furthermore, each end of the bracket 1 away from the fixed block 2 is rotatably connected to a pulley 1, and the middle of both ends of the bracket 1 is rotatably connected to a rotating shaft 1.

[0010] Furthermore, two sliding grooves are formed on the top of the base plate, the pulley is slidably connected to the inner wall of the sliding groove, and the outer wall of the rotating shaft is rotatably connected to the bracket.

[0011] Furthermore, the second bracket is rotatably connected to the inner wall of the first fixing block, and the first fixing block is fixedly connected to the top of the base plate.

[0012] Furthermore, a pulley is rotatably connected to the end of the bracket two away from the fixed block one, and two grooves are opened on the bottom surface of the lifting platform. The two pulleys are slidably connected to the inner walls of the two grooves, respectively. Two triangular fixing blocks are fixedly connected to the bottom surface of the lifting platform, and a threaded rod rotatably passes through the two triangular fixing blocks. A crank handle is fixedly connected to the outer wall of the threaded rod.

[0013] Furthermore, the threaded rod is threadedly connected to a threaded block, and rotating rods are fixedly connected to both sides of the threaded block. The outer walls of the two rotating rods are respectively rotatably connected to two brackets.

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

[0015] 1. By incorporating a sewage pipe fixing mechanism, workers insert the sewage pipe into the circular hole surrounded by four fixing arms, turn the crank handle to rotate the shaft, causing gear one to rotate on the outer wall of the support base. Simultaneously, gear one drives gear two to rotate on the support base, causing the four fixing posts two on the outer wall of gear two to move along an arc. At the same time, the four rotating frames rotate along an arc, causing the end of the fixing arm furthest from fixing post one to rotate around fixing post one within a certain angle, while moving closer to the center of gear two, until all four fixing arms contact the outer wall of the sewage pipe. This fixes the pipe at the center of the support base, preventing misalignment during pipe repair, avoiding the instability and difficulty in precise positioning caused by manually holding the sewage pipe, and solving the problem of reduced efficiency in pipe repair work.

[0016] 2. By setting up a lifting mechanism, rotating the crank two causes the threaded rod to rotate on the inner wall of the triangular fixing block and the threaded block, thereby moving the rotating rod towards the triangular fixing block. At the same time, the pulleys two rotatably connected to the two supports two slide on the inner wall of the slide groove one, and the pulleys one rotatably connected to the two supports one also slide on the inner wall of the slide groove two. The ends of the two supports one and two supports two with pulleys are raised or lowered, thereby raising or lowering the lifting platform. This can facilitate the raising and lowering of sewage pipes, solve the problem that some existing sewage pipe network fixing devices cannot be raised or lowered, and improve the usability of sewage pipe network fixing devices.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 As shown, this utility model is a fixing device for the repair of municipal sewage pipe network, including a base plate 1 and a lifting platform 31. A sewage pipe fixing mechanism 2 and a lifting mechanism 3 are provided on the base plate 1.

[0029] The sewage pipe fixing mechanism 2 includes two support seats 21 fixedly connected to the lifting platform 31. A crank handle 22 is rotatably connected to the side of each support seat 21 that is close to each other. A rotating shaft 29 is fixedly connected to the outer wall of each crank handle 22, passing through the two support seats 21 and rotatably connected to them. A gear 23 is fixedly connected to the outer wall of each rotating shaft 29 away from the crank handle 22. A gear 24 is rotatably connected to the side of each support seat 21 that is far from each other. Gear 24 meshes with gear 23. Four fixing posts 25 are fixedly connected to the outer wall of each support seat 21. A fixing arm 26 is rotatably connected to the outer wall of each of the four fixing posts 25. Four fixing posts 27 are fixedly connected to the outer wall of each of the four fixing posts 24. A rotating frame 28 is rotatably connected to the outer wall of each of the four fixing posts 27. Arm 26 is slidably connected to the inner wall of rotating frame 28. With the sewage pipe fixing mechanism 2, the worker inserts the sewage pipe into the circular hole surrounded by the four fixing arms, turns the crank handle 22, and causes the rotating shaft 29 to rotate. This allows gear 23 to rotate on the outer wall of support base 21. At the same time, gear 23 drives gear 23 to rotate on support base 21, causing the four fixing posts 36 on the outer wall of gear 24 to move along the arc. Simultaneously, the four rotating frames 28 rotate along the arc, causing the end of fixing arm 26 away from fixing post 25 to rotate around fixing post 25 within a certain angle and close to the center of gear 24. This fixes the pipe at the center of the support base, avoiding problems such as misalignment during pipe repair, avoiding the instability and difficulty in precise positioning caused by manually holding the sewage pipe, and solving the problem of reduced efficiency in pipe repair work.

[0030] The lifting mechanism 3 includes a lifting platform 31. Two fixed blocks 39 are fixedly connected to the base of the lifting platform 31. A bracket 33 is rotatably connected to the inner wall of each of the two fixed blocks 39. A pulley 37 is rotatably connected to the end of each bracket 33 away from the fixed blocks 39. A rotating shaft 36 is rotatably connected to the middle of both ends of the bracket 33. Two sliding grooves 38 are formed on the top of the base plate 1. The pulley 37 is slidably connected to the inner wall of the sliding groove 38. A support is rotatably connected to the outer wall of the rotating shaft 36. Frame 2 34 is rotatably connected to the inner wall of fixed block 1 35, which is fixedly connected to the top of base plate 1. A pulley 2 314 is rotatably connected to the end of frame 2 34 away from fixed block 1 35. Two sliding grooves 2 313 are formed on the bottom surface of lifting platform 31, and the two pulleys 2 314 are slidably connected to the inner walls of the two sliding grooves 2 313 respectively. Two triangular fixing blocks 311 are fixedly connected to the bottom surface of lifting platform 31, and a screw thread rotatably passes between the two triangular fixing blocks 311. The threaded rod 312 has a crank handle 32 fixedly connected to its outer wall. The threaded rod 312 is threadedly connected to a threaded block 316. Rotating rods 315 are fixedly connected to both sides of the threaded block 316. The outer walls of the two rotating rods 315 are rotatably connected to two brackets 34 respectively. By setting up a lifting mechanism 3, rotating the crank handle 32 causes the threaded rod 312 to rotate on the inner walls of the triangular fixed block 311 and the threaded block 316, thereby moving the rotating rods 315 towards the triangular fixed block 311. At the same time, the pulleys 314 rotatably connected to the two brackets 34 slide on the inner wall of the slide groove 38. The pulleys 37 rotatably connected to the two brackets 33 also slide on the inner wall of the slide groove 313. The ends of the two brackets 33 and the two brackets 34 with pulleys are raised or lowered, thereby raising or lowering the lifting platform 21. This can facilitate the raising and lowering of sewage pipes, avoid the defect of some existing sewage pipe network fixing devices that cannot be raised or lowered, and improve the usability of the sewage pipe network fixing device.

[0031] A specific application of this embodiment is as follows: By setting up a sewage pipe fixing mechanism 2, the worker inserts the sewage pipe into the circular hole surrounded by four fixing arms, turns the crank handle 22, and causes the rotating shaft 29 to rotate, so that the gear 23 can rotate on the outer wall of the support base 21. At the same time, the gear 23 drives the gear 24 to rotate on the support base, so that the four fixing posts 27 on the outer wall of the gear 24 move along the arc, and the four rotating frames 28 rotate along the arc, so that the end of the fixing arm 26 away from the fixing post 25 rotates around the fixing post 25 within a certain angle and is close to the center of the gear 24, which can fix the pipe at the center of the support base, avoid problems such as misalignment of the pipe during repair, avoid the defects of instability and difficulty in accurate positioning when manually holding the sewage pipe, and solve the problem of reduced efficiency of pipe repair work.

[0032] By setting up the lifting mechanism 3 and rotating the crank 32, the threaded rod 312 rotates on the inner wall of the triangular fixing block 311 and the threaded block 316, thereby moving the rotating rod 315 towards the triangular fixing block 311. At the same time, the pulleys 314 rotatably connected to the two supports 34 slide on the inner wall of the slide groove 38, and the pulleys 37 rotatably connected to the two supports 33 also slide on the inner wall of the slide groove 313. The ends of the two supports 33 and the two supports 34 with pulleys are raised or lowered, thereby raising or lowering the lifting platform 21. This makes it convenient to raise and lower the sewage pipe, avoids the problem that some existing sewage pipe network fixing devices cannot be raised or lowered, and improves the usability of the sewage pipe network fixing device.
