Description

Technical Field

[0001] This utility model relates to the field of pipeline docking technology, and more specifically to a pipeline positioning and docking device. Background Technology

[0002] In water supply pipeline construction, workers often use pipe connectors to position and connect water supply pipelines. A common pipe connector mainly consists of a frame and two clamps that slide within the frame. When using it, the pipes to be connected are clamped in the two clamps respectively, and then the cross-sections of the two pipes are melted with a soldering iron. The two molten cross-sections are then tightly fitted together to complete the pipe welding. During this process, workers need to continuously apply pushing force to the clamps to ensure that the pipe cross-sections are fully heated and can fit tightly together during the connection. Currently, most existing pipe connectors require workers to manually apply continuous pushing force to the clamps. However, the heating and hot-melt connection of the pipes takes a long time, and prolonged manual operation is very strenuous and can easily lead to worker fatigue. Therefore, there is an urgent need to design a pipe positioning and docking device to solve the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pipeline positioning and docking device to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a pipe positioning and docking device, comprising a frame assembly and two clamping assemblies. The frame assembly includes a frame and two fixing rods, both of which are fixedly installed within the frame. The clamping assemblies include a lower clamp and an upper clamp. The lower clamp is slidably sleeved outside the two fixing rods, and the upper clamp is rotatably installed within the lower clamp. The drive assembly includes a bidirectional ball screw, which is rotatably mounted inside the frame, and two clamping assemblies are symmetrically slidably sleeved on the outside of the bidirectional ball screw. Limiting components are installed on the driving components to limit the movement of the driving components.

[0005] Furthermore, the frame assembly also includes two sets of positioning plates, which are fixedly installed on the outside of two fixed rods respectively. Each set consists of two positioning plates, which are symmetrically fixedly installed on the outside of the fixed rods.

[0006] Furthermore, the clamping assembly also includes a ball sleeve, which is fixedly installed at the bottom of the lower clamp and is slidably connected to the outside of the bidirectional ball screw via a thread.

[0007] Furthermore, the clamping assembly also includes a positioning plate, and a slot is provided on the top of the upper clamp, with the positioning plate rotatably mounted in the slot.

[0008] Furthermore, the drive assembly also includes two support plates, a rotating rod, a crank handle, a first bevel gear, and a second bevel gear. Both support plates are fixedly mounted on the frame, the rotating rod is rotatably mounted between the two support plates, the crank handle is fixedly mounted on one end of the rotating rod, the first bevel gear is fixedly mounted on the other end of the rotating rod, and the second bevel gear is fixedly mounted outside the bidirectional ball screw. The first bevel gear meshes with the second bevel gear.

[0009] Furthermore, the drive assembly also includes a ratchet, which is fixedly mounted on the outside of the rotating rod.

[0010] Furthermore, the limiting component includes a bracket, two sliding rods, a ratchet, and two springs. The bracket is fixedly mounted on the drive component, the two sliding rods are slidably mounted inside the bracket, the ratchet is fixedly mounted at the bottom of the two sliding rods, and the two springs are fixedly mounted between the ratchet and the bracket. The ratchet engages with the drive component.

[0011] Furthermore, the limiting assembly also includes a lever, which is fixedly mounted on the top of the two sliding rods.

[0012] The technical effects and advantages of this utility model are as follows: This invention involves fixing two pipes and placing a soldering iron on them. Turning the handle clockwise causes the rotating rod and the first bevel gear to rotate clockwise, which in turn causes the second bevel gear and the bidirectional ball screw to rotate clockwise. This causes the two clamping components and the two pipes to slide closer to each other, allowing the two pipes to come into contact with the soldering iron for heating. The ratchet prevents the ratchet and the rotating rod from rotating counterclockwise, thus locking the two pipes onto the soldering iron without requiring continuous manual application of force. After heating is complete, slide the lever upwards to compress the spring and disengage the ratchet from the ratchet. Then, turn the crank counterclockwise to rotate the rotating rod and the first bevel gear counterclockwise, which in turn rotates the second bevel gear and the double-sided ball screw counterclockwise. This causes the two clamping components and the two pipes to slide away from each other, allowing the two pipes to disengage from the soldering iron. Release the lever, and the spring will release and push the ratchet to re-engage with the ratchet. Then, turn the crank clockwise to make the ends of the two pipes fit tightly together for docking. After docking, open the two upper clamps to remove the docked pipes. During heating and hot-melt docking, the operator does not need to continuously apply force to the two pipes, and it is not easy to cause fatigue even after long-term use.

[0015] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 4 The present invention will be further described below.

[0017] A pipe positioning and docking device includes a frame assembly 1 and two clamping assemblies 2. The frame assembly 1 includes a frame 101 and two fixing rods 102, both of which are fixedly installed inside the frame 101. The clamping assemblies 2 include a lower clamp 201 and an upper clamp 202. The lower clamp 201 is slidably sleeved on the outside of the two fixing rods 102, and the upper clamp 202 is rotatably installed inside the lower clamp 201. Drive assembly 3 includes a bidirectional ball screw 301, which is rotatably mounted inside the frame 101, and two clamping assemblies 2 are symmetrically slidably sleeved on the outside of the bidirectional ball screw 301. Limiting component 4 is installed on driving component 3 and can limit the driving component 3.

[0018] Specifically, the frame assembly 1 also includes two sets of positioning plates 103. The two sets of positioning plates 103 are fixedly installed on the outside of the two fixing rods 102 respectively. Each set consists of two plates, and the two positioning plates 103 are symmetrically fixedly installed on the outside of the fixing rods 102.

[0019] In this embodiment, the positioning piece 103 can help position the soldering iron so that the soldering iron is just in the middle of the fixing rod 102.

[0020] Specifically, the clamping assembly 2 also includes a ball sleeve 203, which is fixedly installed at the bottom of the lower clamp 201 and is threadedly slidably connected to the outside of the bidirectional ball screw 301.

[0021] In this embodiment, the clockwise rotation of the bidirectional ball screw 301 can cause the two ball sleeves 203 to slide closer to each other, and the counterclockwise rotation of the bidirectional ball screw 301 can cause the two ball sleeves 203 to slide further apart.

[0022] Specifically, the clamping assembly 2 also includes a positioning plate 205, and a strip groove 204 is provided on the top of the upper clamp 202. The positioning plate 205 is rotatably installed in the strip groove 204.

[0023] In this embodiment, the positioning plate 205 can assist the operator in determining the distance that the pipe end passes through the clamping assembly 2, so that the two pipes that need to be connected pass through the clamping assembly 2 at the same distance.

[0024] Specifically, the drive assembly 3 also includes two support plates 302, a rotating rod 303, a crank handle 304, a first bevel gear 306, and a second bevel gear 307. Both support plates 302 are fixedly mounted on the frame 101. The rotating rod 303 is rotatably mounted between the two support plates 302. The crank handle 304 is fixedly mounted on one end of the rotating rod 303. The first bevel gear 306 is fixedly mounted on the other end of the rotating rod 303. The second bevel gear 307 is fixedly mounted outside the bidirectional ball screw 301. The first bevel gear 306 and the second bevel gear 307 mesh with each other.

[0025] In this embodiment, rotating the crank handle 304 clockwise causes the rotating rod 303 and the first bevel gear 306 to rotate clockwise, which in turn causes the second bevel gear 307 and the bidirectional ball screw 301 to rotate clockwise. The clockwise rotation of the bidirectional ball screw 301 causes the two ball sleeves 203 to slide closer to each other, thereby causing the two lower clamps 201, the two upper clamps 202, and the two pipes to slide closer to each other. Conversely, rotating the crank handle 304 counterclockwise causes the two pipes to slide further away from each other.

[0026] Specifically, the drive assembly 3 also includes a ratchet 305, which is fixedly installed outside the rotating rod 303. The limiting assembly 4 includes a bracket 401, two sliding rods 402, a ratchet 403, and two springs 404. The bracket 401 is fixedly installed on the drive assembly 3. The two sliding rods 402 are slidably installed inside the bracket 401. The ratchet 403 is fixedly installed at the bottom of the two sliding rods 402. The two springs 404 are fixedly installed between the ratchet 403 and the bracket 401. The ratchet 403 meshes with the drive assembly 3.

[0027] In this embodiment, the bracket 401 is fixedly installed on one of the support plates 302. The ratchet 403 is engaged in the ratchet 305 under the push of the spring 404, limiting the ratchet 305 so that it cannot rotate counterclockwise. This limits the rotating rod 303, thereby limiting the first bevel gear 306 and the second bevel gear 307, and further limiting the bidirectional ball screw 301, the two clamping assemblies 2, and the two pipes.

[0028] Specifically, the limiting component 4 also includes a paddle 405, which is fixedly installed on the top of the two sliding rods 402.

[0029] In this embodiment, sliding the paddle 405 upwards causes the ratchet 403 to disengage from the ratchet 305, thereby releasing the limit on the counterclockwise rotation of the rotating rod 303.

[0030] Working principle: In use, place the two pipes to be connected into the two lower clamps 201 respectively, and then fasten the two upper clamps 202. At this time, move the two pipes into the frame 101 so that the ends of the two pipes are respectively attached to the inner sides of the two positioning plates 205, so that the distance between the ends of the two pipes and the two clamping components 2 is the same. Then, lock the two upper clamps 202 and rotate the two positioning plates 205 upwards by 180 degrees. At this time, place the soldering iron between the two positioning plates 103. After the soldering iron is preheated, turn the crank handle 304 clockwise to drive the rotating rod 303 and the first bevel gear. Rotating handle 306 clockwise will drive the second bevel gear 307 and the double-sided ball screw 301 to rotate clockwise. The clockwise rotation of the double-sided ball screw 301 will cause the two ball sleeves 203 to slide closer together, thereby causing the two lower clamps 201, the two upper clamps 202, and the two pipes to slide closer together. When the rotating rod 303 rotates clockwise, it will also drive the ratchet 305 to rotate clockwise. The ratchet 305 will not be blocked by the ratchet 403 when rotating clockwise, and can repeatedly push the ratchet 403 upwards and compress the spring 404, sliding the ends of the two pipes until they are in close contact with the soldering iron. Then, release the crank handle 30. 4. At this time, the ratchet 403, pushed by the spring 404, engages with the ratchet 305, limiting the ratchet 305 to prevent it from rotating counterclockwise. This limits the rotating rod 303, thereby limiting the first bevel gear 306 and the second bevel gear 307, and further limiting the bidirectional ball screw 301, the two clamping assemblies 2, and the two pipes. The operator does not need to continuously apply pushing force to the two pipes. After heating is complete, slide the lever 405 upward to compress the spring 404 and drive the ratchet 403 to disengage from the ratchet 305. At this time, turn the crank 304 counterclockwise to drive the rotating rod 303 and the first bevel gear 306 to rotate counterclockwise. The second bevel gear 307 and the double-direction ball screw 301 are rotated counterclockwise. The counterclockwise rotation of the double-direction ball screw 301 can drive the two ball sleeves 203 to slide away from each other, thereby driving the two lower clamps 201, the two upper clamps 202 and the two pipes to slide away from each other. After the two pipes are separated from the soldering iron, the lever 405 is released. At this time, the spring 404 will be released and push the ratchet 403 to re-engage with the ratchet 305. Then, the crank handle 304 is turned clockwise to make the ends of the two pipes fit tightly together, so that they can be connected. After the connection is completed, the two upper clamps 202 are opened and the connected pipes can be taken out.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
