Description

Technical Field

[0001] This utility model relates to the field of maintenance tool technology, specifically to a disassembly and assembly assembly for a double-flange force transmission joint. Background Technology

[0002] Double-flange force transmission joints are key components in piping systems used to connect two pipe sections. They achieve axial force transmission and a certain degree of displacement compensation through the connection of nuts between the flanges at both ends and the pipe flanges. They are widely used in water supply and drainage, chemical, and municipal engineering fields. Traditionally, their assembly and disassembly process relies on manual tightening or loosening of the connecting nuts using a wrench.

[0003] Double-flange force transmission joints are often installed in densely piped areas with narrow surrounding space, making it difficult for wrenches to apply force from all directions. Especially when there are many nuts (usually 8-24 sets), the wrench angle needs to be adjusted repeatedly. The disassembly and assembly of a single joint takes a long time, which seriously affects the efficiency of pipeline maintenance. In view of this, a disassembly and assembly component for double-flange force transmission joints is proposed. Utility Model Content

The fixing mechanism includes: A hollow ring passes through and is rotatably connected to the connector. A limiting ring is fixedly connected to the outer wall of the hollow ring for positioning the connector. An adjustable positioning component is disposed at the end of a hollow ring; And a large gear, wherein the large gear is fixed to the hollow ring.

[0006] Preferably, the adjustable positioning component includes a connecting ring, which is fixed to the hollow ring. A groove is provided on the side of the connecting ring near the rotating ring, and a limit rod is slidably connected in the groove. The limit rod passes through the positioning block and is fixedly connected to the positioning block.

[0007] Preferably, the rotating ring is sleeved on the outer wall of the connecting ring, the rotating ring has a straight groove, the rotating ring is fixed to the reinforcing ring, the straight groove slides with the limiting rod, and a clamping nut is threaded onto the outer wall of the rotating ring.

[0008] Preferably, there are six sets of limiting rods and positioning blocks, and the six sets of limiting rods and positioning blocks are arranged in a circular array at equal intervals along the central axis of the connecting ring. The number of sets of straight slots is the same as the number of sets of limiting rods.

[0009] Preferably, by rotating the rotating ring, the limiting rod slides in the straight groove and the sliding groove, so that the six sets of positioning blocks move synchronously, and the positioning area formed is a regular hexagon.

[0010] Preferably, a connecting shaft is rotatably connected to the connector, the connecting shaft passes through and is fixed to the pinion, the pinion meshes with the large gear, and the output shaft of the micro motor is fixed to the connecting shaft.

[0012] This utility model provides a disassembly and assembly assembly for a double-flange force transmission joint. It has the following advantages: (1) The assembly and disassembly of the double flange force transmission joint uses a fixing mechanism, a micro motor, a rotating shaft and a small gear. After the nut is fixed, the micro motor drives the connecting shaft to rotate by holding the handle.

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.

[0019] Please see Figures 1-7 This utility model proposes a disassembly and assembly assembly for a double-flange force transmission joint, including a handle 1, a connector 2 fixedly connected to the end of the handle 1, a fixing mechanism 3 provided in the connector 2, and a micro motor 4 fixedly connected to the outer wall of the connector 2. The micro motor 4 is powered by a battery installed in the handle 1. When the operator holds the handle 1, the fixing mechanism 3 in the connector 2 aligns with the nut on the double-flange force transmission joint, and the micro motor 4 is started. The battery in the handle 1 powers the micro motor 4, and the output torque of the micro motor 4 drives the fixing mechanism 3 to rotate, thereby realizing the tightening and loosening of the nut.

[0020] In an embodiment of this utility model, in order to achieve the fixing of nuts of different diameters, the fixing mechanism 3 specifically includes a hollow ring 31, an adjustable positioning component 32, and a large gear 34. The hollow ring 31 passes through the connector 2 and is rotatably connected to the connector 2. A limit ring 33 is fixedly connected to the outer wall of the hollow ring 31. The limit ring 33 is used to position the connector 2. The adjustable positioning component 32 is disposed at the end of the hollow ring 31. The large gear 34 is fixed to the hollow ring 31. The adjustable positioning component 32 includes a connecting... Ring 321, connecting ring 321 is fixed to hollow ring 31. A groove 322 is formed on the side of connecting ring 321 near rotating ring 327. A limit rod 323 is slidably connected in the groove 322. The limit rod 323 passes through positioning block 324 and is fixedly connected to positioning block 324. Rotating ring 327 is sleeved on the outer wall of connecting ring 321. A straight groove 325 is formed on rotating ring 327. Rotating ring 327 is fixed to reinforcing ring 326. The straight groove 325 slides with the limit rod 323. A clamping nut 328 is threaded onto the outer wall. Six sets of limiting rods 323 and positioning blocks 324 are provided, arranged in a circular array equidistant from the central axis of the connecting ring 321. The number of sets of straight slots 325 is the same as the number of sets of limiting rods 323. By rotating the rotating ring 327, the limiting rods 323 slide within the straight slots 325 and the sliding grooves 322, causing the six sets of positioning blocks 324 to move synchronously. The resulting positioning area is a regular hexagon. Adjustments are made according to the nut size by rotating... Loosen the clamping nut 328, then rotate the rotating ring 327. Its straight groove 325 pushes the limiting rod 323 to slide along the sliding groove 322 of the connecting ring 321. The six sets of positioning blocks 324 move closer to or further away from the center with the limiting rod, forming a regular hexagonal positioning area that matches the nut. After adjustment, tighten the clamping nut 328 to fix the position of the rotating ring 327, ensuring that the adjustable positioning component 32 is accurately connected to the nut. It can be adapted to nuts of various sizes, eliminating the need for frequent tool changes and solving the problem of the single specification of traditional wrenches.

[0021] Furthermore, in order to quickly assemble and disassemble the nuts on the double-flange force transmission joint, specifically, a connecting shaft 22 is rotatably connected in the connector 2. The connecting shaft 22 passes through and is fixed to the pinion 21. The pinion 21 meshes with the large gear 34. The output shaft of the micro motor 4 is fixed to the connecting shaft 22. After the nut is fixed, the micro motor 4 is started, and its output shaft drives the connecting shaft 22 and the pinion 21 to rotate. The pinion meshes with the large gear 34, driving the hollow ring 31 and the adjustable positioning component 32 to rotate as a whole, thereby driving the nut to rotate to achieve tightness or looseness. There is no need to make significant adjustments to the angle of the handle 1. Compared with traditional wrenches, this avoids the difficulty of applying force due to narrow space, reduces the need for repeated tool adjustments, and makes the assembly and disassembly process more convenient, making it suitable for operation in densely piped areas.

No specific restrictions are imposed here. In use, first adjust according to the nut size, loosen the clamping nut 328 by rotating it, then rotate the rotating ring 327. Its straight groove 325 pushes the limiting rod 323 to slide along the sliding groove 322 of the connecting ring 321. The six sets of positioning blocks 324 move closer to or further away from the center with the limiting rod, forming a regular hexagonal positioning area that matches the nut. After adjustment, tighten the clamping nut 328 to fix the position of the rotating ring 327. Then start the micro motor 4. Its output shaft drives the connecting shaft 22 and the small gear 21 to rotate. The small gear meshes with the large gear 34 to drive the hollow ring 31 and the adjustable positioning component 32 to rotate as a whole, thereby driving the nut to rotate to achieve tightening or loosening.
