Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to a quick connection device for municipal pipeline maintenance. Background Technology

[0002] Municipal pipelines, as a crucial component of urban infrastructure, undertake key functions such as water supply, drainage, gas transmission, and heat transfer. Their operational stability directly impacts the normal lives of urban residents and the orderly conduct of industrial production. However, during long-term use, municipal pipelines are prone to ruptures, leaks, and joint detachment due to factors such as geological subsidence, media corrosion, external impacts, and aging wear. If not repaired promptly, these malfunctions not only waste water and energy resources but may also lead to road collapses, environmental pollution, gas leaks, and other safety accidents, posing a serious threat to urban public safety and the ecological environment.

[0003] In municipal pipeline maintenance, pipeline connection is one of the core procedures, and its efficiency and quality directly determine the length of the maintenance period and the reliability of operation. Currently, the industry mainly uses flange connections or welding connections for the repair of damaged pipelines.

[0004] Traditional flange connections require sequential steps such as flange welding, fixing, gasket installation, bolt insertion, and multi-point tightening, involving multiple processes and tools. They also require a high degree of consistency in bolt tightening torque, making it difficult for a single person to operate quickly. Welded connections, on the other hand, require professional welders to bring heavy welding equipment to the site. Furthermore, the welded area needs to be pre-treated and subsequently inspected (such as airtightness tests). This not only results in a long operation cycle but is also subject to strict limitations imposed by site space and weather conditions (such as rain, snow, and strong winds), making it difficult to meet the timeliness requirements of municipal pipeline "emergency repairs."

[0009] Preferably, the positioning mechanism includes a positioning groove, a positioning frame, and a position adjustment mechanism. The inner wall of the positioning ring is provided with a plurality of positioning grooves. The positioning frame is slidably disposed in the positioning grooves.

The cam is rotatably disposed in the positioning groove, extending into the positioning frame and contacting the inner wall of the positioning frame. The first rotation mechanism is disposed on the positioning ring and is used to drive multiple cams to rotate synchronously.

[0011] Furthermore, the first rotating mechanism includes a first cavity, a first gear ring, and a driving mechanism. The positioning ring has an annular first cavity on one side of the positioning groove. A first gear is rotatably disposed in the first cavity on one side of the cam. A connecting column is fixedly disposed between the first gear and the cam. The first gear ring is rotatably disposed in the first cavity and meshes with the first gear. The driving mechanism is disposed on the positioning ring and is used to drive the first gear to rotate.

[0012] Furthermore, the driving mechanism includes a first driving port, a second driving port, a driving prism, and a first handwheel. The first driving port is located on the positioning ring, and the second driving port is located on one of the first gears. The first driving port passes through the adjacent connecting post and the cam.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a quick connection device for municipal pipeline maintenance, which has the following advantages:

[0016] 1. In this utility model, through the setting of the positioning mechanism, the rotation of the first handwheel drives the drive prism to rotate, and at the same time, the sliding cooperation between the drive prism and the second drive port drives the first gear to rotate. Then, the meshing of the first gear and the first gear ring drives multiple first gears and multiple cams to rotate synchronously. During the rotation of the cam, the cam can squeeze the inner wall of the positioning frame to drive the positioning frame to retract into the positioning groove. After that, the sealing ring is inserted into the sealing groove and the first handwheel is released. Then, the positioning frame can be extended out of the positioning groove by the support spring, so as to facilitate the positioning of the two sealing rings by the two positioning frames.

[0017] 2. In this utility model, by setting up a relative moving mechanism, the rotation of the second handwheel can drive the bidirectional screw to rotate. At the same time, the threaded engagement between the bidirectional screw and the positioning ring drives the positioning ring and the positioning frame to move, thereby facilitating the clamping of the two sealing rings through the positioning frame and thus facilitating the quick connection of the pipe body.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-5 A quick-connection device for municipal pipeline maintenance, used to connect and fix pipeline bodies 1, includes a sealing ring 2, which is fixedly installed on the side wall of the pipeline body 1. A sealing ring 3 is fixedly installed on the side wall of the sealing ring 2. It also includes an installation ring 4, a positioning ring 6, a relative movement mechanism, and a positioning mechanism. The installation ring 4 is installed on the periphery of the pipeline body 1. An annular installation groove 5 is opened on the inner wall of the installation ring 4. Two positioning rings 6 are slidably installed in the installation groove 5. The relative movement mechanism is installed on the two positioning rings 6 and is used to drive the two positioning rings 6 to move relative to each other. The positioning mechanism is installed on the positioning rings 6 and is used to position the positioning rings 6 and the sealing ring 2.

[0026] Reference Figures 1-5 The positioning mechanism includes a positioning groove 7, a positioning frame 8, and a position adjustment mechanism. Multiple positioning grooves 7 are formed on the inner wall of the positioning ring 6. The positioning frame 8 is slidably disposed within the positioning grooves 7. The position adjustment mechanism is disposed on the positioning ring 6 and is used to drive the positioning frame 8 to adjust its position within the positioning grooves 7. The position adjustment mechanism includes a support spring 9, a cam 10, and a first rotation mechanism. The support spring 9 is fixedly disposed between the positioning frame 8 and the bottom of the positioning groove 7. The cam 10 is rotatably disposed within the positioning groove 7, extending into the positioning frame 8 and contacting its inner wall. The first rotation mechanism is disposed on the positioning ring 6 and is used to drive multiple cams 10 to rotate synchronously. Specifically, the operation of the first rotation mechanism drives the cams 10 to rotate. The cams 10 press against the inner wall of the positioning frame 8, causing the positioning frame 8 to retract into the positioning groove 7. Then, the sealing rings 2 are inserted into the sealing grooves, and the first handwheel 17 is released. The support spring 9 allows the positioning frame 8 to extend out of the positioning groove 7, thus facilitating the positioning of the two sealing rings 2 using the two positioning frames 8.

[0027] Reference Figures 2-5 The first rotating mechanism includes a first cavity 11, a first gear ring 13, and a driving mechanism. An annular first cavity 11 is formed within the positioning ring 6 on one side of the positioning groove 7. A first gear 12 is rotatably mounted within the first cavity 11 on one side of the cam 10. A connecting post is fixedly mounted between the first gear 12 and the cam 10. The first gear ring 13 is rotatably mounted within the first cavity 11 and meshes with the first gear 12. The driving mechanism is mounted on the positioning ring 6 and is used to drive the first gear 12 to rotate. The driving mechanism includes a first driving port 14, a second driving port 15, a driving prism 16, and a first handwheel 17. The first driving port 14 is located on the positioning ring 6, and the second driving port 15 is located on one of the first driving ports. On gear 12, the first drive port 14 passes through the adjacent connecting post and cam 10. The drive prism 16 is rotatably disposed in the mounting groove 5. The drive prism 16 passes through the first drive port 14 and the second drive port 15. The drive prism 16 is slidably connected to the side wall of the second drive port 15. The first handwheel 17 is rotatably disposed on the side wall of the mounting ring 4. The first handwheel 17 is fixedly connected to the drive prism 16. Specifically, the rotation of the first handwheel 17 drives the drive prism 16 to rotate. At the same time, the sliding cooperation between the drive prism 16 and the second drive port 15 drives the first gear 12 to rotate. Then, the meshing of the first gear 12 with the first gear ring 13 drives multiple first gears 12 and multiple cams 10 to rotate synchronously.

[0028] Reference Figure 2 and Figure 3 The relative movement mechanism includes a bidirectional screw 18 and a second handwheel 19. The bidirectional screw 18 is rotatably mounted in the mounting groove 5 and passes through two positioning rings 6 via a threaded connection. The second handwheel 19 is rotatably mounted on the outer wall of the mounting ring 4 and is fixedly connected to the bidirectional screw 18. Multiple guide rods are fixedly mounted in the mounting groove 5. The guide rods pass through the positioning rings 6 and are slidably connected to the positioning rings 6. Specifically, the rotation of the second handwheel 19 can drive the bidirectional screw 18 to rotate. At the same time, the threaded connection between the bidirectional screw 18 and the positioning rings 6 drives the positioning rings 6 and the positioning frame 8 to move, thereby facilitating the clamping of the two sealing rings 2 by the positioning frame 8 and thus facilitating the quick connection of the pipe body 1.

[0029] It should also be noted that this device is only used to temporarily connect and fix the pipes during pipeline maintenance. After the pipeline maintenance is completed, other methods can be used to achieve a stable connection and fixation between the pipes.

[0030] Working principle: During use, the operator rotates the first handwheel 17, which drives the drive prism 16 to rotate. Simultaneously, the sliding engagement between the drive prism 16 and the second drive port 15 drives the first gear 12 to rotate. The meshing of the first gear 12 with the first gear ring 13 then drives multiple first gears 12 and multiple cams 10 to rotate synchronously. During the rotation of the cams 10, the pressure exerted by the cams on the inner wall of the positioning frame 8 causes the positioning frame 8 to retract into the positioning groove 7. Then, the sealing ring 2 is inserted into the two sealing grooves. After the sealing ring 2 is inserted into the sealing groove, the first handwheel 17 is released, so that the positioning frame 8 can be extended out of the positioning groove 7 by the support spring 9. This facilitates the positioning of the two sealing rings 2 by the two positioning frames 8. Then, the operator turns the second handwheel 19. The rotation of the second handwheel 19 can drive the bidirectional screw 18 to rotate. At the same time, the threaded engagement between the bidirectional screw 18 and the positioning ring 6 drives the positioning ring 6 and the positioning frame 8 to move. This facilitates the clamping of the two sealing rings 2 by the positioning frame 8, thereby facilitating the quick connection of the pipe body 1.
