A supplementary docking device for a drain pipe

Abstract

This utility model discloses an auxiliary docking device for drainage pipes, relating to the field of auxiliary pipe docking technology. The utility model includes a docking plate and a clamp adjustment assembly. The clamp adjustment assembly includes two sliding tables symmetrically fixed to the sides of the docking plate. Sliding rods are slidably connected within the docking plate, and a horizontal plate is fixedly connected between the two corresponding sliding rods. An arc-shaped strip is fixedly connected between the two horizontal plates, and an insertion rod is fixedly connected to the side of the horizontal plate. A clamping strip is slidably connected within the sliding tables, and several insertion holes are evenly distributed on the clamping strip. By providing two slidable clamping strips on the docking plate, this utility model allows for the outward movement of the arc-shaped strip during auxiliary docking of pipes of different diameters. This releases the clamping strip's restriction, allowing for free adjustment of its position. This avoids the need to replace the auxiliary docking device when the pipe size exceeds or falls below the clamping range of the clamp, thus improving the efficiency of auxiliary pipe docking.

Description

Technical Field

[0001] This utility model relates to the field of auxiliary pipe connection technology, and in particular to an auxiliary connection device for drainage pipes. Background Technology

[0002] Drainage pipes are a collective term for pipe systems and their ancillary structures buried underground or inside buildings, specifically used for collecting and transporting sewage, wastewater, and rainwater generated during domestic and industrial activities. They are an indispensable infrastructure of modern cities and buildings. When assembling drainage pipes, two pipes need to be connected and then sealed.

[0003] When using existing equipment to assist in the connection of drainage pipes, the existing equipment uses a clamping method, with the clamping plates moving relative to each other to fix the two drainage pipes in a coaxial position and push the two pipe ends to align, thereby completing the auxiliary connection of the drainage pipes.

[0004] However, in actual use, due to the large differences in the diameter of drainage pipes, the clamping range of the fixture is limited when assisting in the connection of pipes of different diameters. When assisting in the connection of large or small pipes, it is necessary to replace the auxiliary connection device, which reduces the efficiency of production work. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the limited range of clamping and docking in existing technologies, which necessitates the replacement of auxiliary docking devices when docking large or small pipes, thus reducing production efficiency. Therefore, this invention proposes an auxiliary docking device for drainage pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an auxiliary docking device for drainage pipes, including a docking plate and a clamp adjustment assembly. The clamp adjustment assembly includes two slides symmetrically fixed to the sides of the docking plate. A slide rod is slidably connected inside the docking plate. A horizontal plate is fixedly connected between two corresponding slide rods. An arc-shaped strip is fixedly connected between the two horizontal plates. An insertion rod is fixedly connected to the side of the horizontal plate. A clamping strip is slidably connected inside the slides. Several insertion holes are evenly provided on the clamping strip. The insertion rod is inserted into the insertion holes.

[0008] Preferably, a baffle is fixedly connected to the periphery of the slide bar, and a spring is fixedly connected to the side of the baffle, with the spring being fixedly connected to the docking plate.

[0009] Preferably, a mounting platform is fixedly connected to the surface of the clamping strip, and two rotating shafts are symmetrically rotatably connected to the mounting platform. Arc-shaped clamping plates are fixedly connected to the circumferential side of the rotating shafts.

[0010] Preferably, an arc-shaped clamping strip is fixedly connected to the side of the arc-shaped clamping plate.

[0011] Preferably, a threaded rod is rotatably connected through the mounting platform, a slider is slidably connected to the mounting platform, the slider and the threaded rod are threadedly connected, racks are fixedly connected to both opposite sides of the slider, and a gear is fixedly connected to the rotating shaft above the arc-shaped clamp, with the rack and gear meshing with each other.

[0012] Preferably, a handwheel is fixedly connected to the end of the threaded rod.

[0013] Preferably, the two clamping bars are at the same distance from the center of the mating plate.

[0014] Preferably, the included angle between each of the arc-shaped clamps and the rack is the same.

[0015] The present invention provides an auxiliary docking device for drainage pipes, which has the following advantages: by pulling the arc-shaped strip outward, the arc-shaped strip moves and pulls the insertion rod out of the insertion hole, thereby releasing the limitation on the clamping strip. The position of the clamping strip can be adjusted on the slide table, so that the device can be adapted to assist docking work for drainage pipes of different sizes. It can avoid the need to replace the clamp when the pipe is larger or smaller than the clamping range of the clamp, thus improving work efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-4 This utility model is an auxiliary docking device for drainage pipes, including a docking plate 1 and a clamp adjustment assembly. The clamp adjustment assembly includes two slides 2, which are symmetrically fixed on the sides of the docking plate 1. A slide rod 3 is slidably connected inside the docking plate 1. A horizontal plate 4 is fixedly connected between the two corresponding slide rods 3. An arc-shaped strip 5 is fixedly connected between the two horizontal plates 4. An insertion rod 10 is fixedly connected to the side of the horizontal plate 4. A clamping strip 8 is slidably connected inside the slides 2. Several insertion holes 9 are evenly opened on the clamping strip 8. The insertion rod 10 is inserted into the insertion holes 9.

[0025] A baffle 6 is fixedly connected to the side of the slide bar 3, and a spring 7 is fixedly connected to the side of the baffle 6. The spring 7 is fixedly connected to the docking plate 1.

[0026] The operation process of this embodiment is as follows: According to the size of the drainage pipe, the arc-shaped strip 5 is pulled outward. The movement of the arc-shaped strip 5 causes each sliding rod 3 to move away from the docking plate 1. In the initial state, the insertion rod 10 is inserted into the corresponding insertion hole 9, limiting the lateral movement of the clamping strip 8. At this time, as the arc-shaped strip 5 moves outward, the insertion rod 10 is pulled out from the insertion hole 9, and the clamping strip 8 loses the limitation of the insertion rod 10. According to the size of the pipe, the position of the two clamping strips 8 is adjusted so that the distance between them is slightly larger than the pipe diameter. After adjustment, the arc-shaped strip 5 is released, the spring 7 pulls the baffle 6 and the sliding rod 3 to reset, and the insertion rod 10 is reinserted into its corresponding insertion hole 9, completing the adjustment of the position of the two clamping strips 8. The clamping strips 8 limit the position of the drainage pipe and assist in docking. Thus, when assisting in docking pipes of different sizes, the position of the two clamping strips 8 can be adjusted to avoid the pipe being outside or inside the range of use of the clamp, thus requiring the replacement of a new clamp, improving the working efficiency when assisting in docking drainage pipes.

[0027] Example 2

[0028] In actual use, the two clamping bars 8 can only initially limit the position of the drain pipe. During the pipe connection process, the pipe may still wobble. Therefore, please refer to [the relevant documentation / reference]. Figure 2-3Based on the first specific embodiment, a mounting platform 11 is fixedly connected to the surface of the clamping bar 8. Two rotating shafts 12 are symmetrically rotatably connected to the mounting platform 11. Arc-shaped clamping plates 13 are fixedly connected to the circumference of the rotating shafts 12. Arc-shaped clamping bars 15 are fixedly connected to the sides of the arc-shaped clamping plates 13. A threaded rod 16 is rotatably connected through the mounting platform 11. A slider 17 is slidably connected to the mounting platform 11. The slider 17 is threadedly connected to the threaded rod 16. A rack 18 is fixedly connected to both opposite sides of the slider 17. A gear 14 is fixedly connected to the rotating shaft 12 above the arc-shaped clamping plate 13. The rack 18 and the gear 14 mesh with each other. A handwheel 19 is fixedly connected to the end of the threaded rod 16. The two clamping bars 8 are equidistant from the center of the mating plate 1. The included angle between each arc-shaped clamping plate 13 and the rack 18 is the same.

[0029] The operation process of this embodiment is as follows: After the initial position of the pipeline is defined, the handwheel 19 is rotated. The rotation of the handwheel 19 drives the threaded rod 16 to rotate. Since the slider 17 is in sliding fit with the mounting platform 11 and is threadedly connected to the threaded rod 16, the slider 17 moves laterally along the threaded rod 16. The two opposite sides of the slider 17 are fixedly connected with racks 18, and the racks 18 mesh with the gears 14. That is, when the handwheel 19 is rotated, it can drive the two corresponding gears 14 to rotate synchronously in opposite directions. The rotation of the gears 14 drives the rotating shaft 12 to rotate synchronously in opposite directions. The curved clamping bar 15 on one side rotates inward to clamp the drainage pipe. The handwheels 19 on both sides rotate the same number of times, which not only fixes the drainage pipe to be processed, but also keeps it in the center position of the docking plate 1. When assisting in docking the drainage pipe, two sets of devices are used and the two docking plates 1 are parallel to each other to clamp the two pipes and keep them in the coaxial position. By rotating the two curved clamping bars 15 in opposite directions at the same time, the drainage pipe can be firmly clamped, thereby improving the stability of the drainage pipe after auxiliary docking and further improving the practicality of the device.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
