Description

Technical Field

[0001] This utility model relates to the field of spiral wound pipe technology, and in particular to HDPE polyethylene spiral wound pipe forming equipment. Background Technology

[0002] Polyethylene-plastic composite spiral wound pipe is made of steel-plastic composite profiled strip spirally wound and welded. Its inner wall is smooth and flat. This type of pipe has advantages such as corrosion resistance, light weight, easy installation, large flow capacity, and long service life. Some existing spiral wound pipes are quite large. Therefore, after production and cutting, a moving mechanism is needed to move the spiral wound pipe to the subsequent process or placement location. However, existing moving mechanisms cannot effectively limit and fix both ends of the spiral wound pipe during actual use, which may cause the pipe to slip during movement, potentially leading to frictional damage.

[0003] Chinese utility model patent CN222116881U discloses a pipe moving mechanism for a spiral wound tube forming machine, relating to the field of spiral wound tube production technology. The mechanism includes: a worktable; a movable plate at the bottom of the worktable; multiple movable wheels at the bottom of the movable plate; limit components on both sides of the outer end of the worktable for limiting the movement of the spiral wound tube; and a lifting component at the top of the worktable for lifting the spiral wound tube. This pipe moving mechanism of the spiral wound tube forming machine can limit both ends of the spiral wound tube through the limit components, preventing friction damage caused by the tube moving back and forth during movement. The lifting component facilitates adjusting the spiral wound tube to different heights, facilitating subsequent processing.

[0004] Regarding the aforementioned technology, the inventors believe it suffers from the following drawbacks: The device uses two movable plates driven by lead screws to adjust the position of the limiting plates, thereby limiting the two ends of the winding tube. In actual use, the lead screw rotation driving the movable plates easily results in limited movement speed of the plates. Workers must hold the winding tube and wait for the two limiting plates to separate before placing the tube between them, and then sequentially control the two motors to reverse, causing the limiting plates to press against the ends of the winding tube. This operation is complex, provides a poor user experience, and is detrimental to improving production efficiency. Utility Model Content

[0005] To solve the above problems, this utility model provides HDPE polyethylene spiral pipe forming equipment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: HDPE polyethylene spiral pipe forming equipment, including a worktable, movable wheels set on the bottom surface of the worktable, support rods set on the upper surface of the worktable, a top plate set on the support rods, and a lifting assembly set on the worktable. A first sliding groove is provided on one side wall of the worktable, and a first sliding rod is slidably arranged in the first sliding groove. A second sliding groove is provided on the other side wall of the worktable, and a second sliding rod is slidably arranged in the second sliding groove. Limiting plates are provided on the side walls of the first sliding rod and the second sliding rod that are far apart from each other. A limiting assembly for limiting the first sliding rod is provided on the worktable.

[0007] By adopting the above technical solution, when workers produce polyethylene spiral wound pipes, during the initial forming stage, the spiral wound pipes need to be cut and subsequently ground and shaped. At this time, workers need to place the cut spiral wound pipes on a lifting assembly and adjust their height using the lifting assembly. During this process, workers need to pull the second sliding rod to move it to its furthest point. Further, workers need to press one end of the spiral wound pipe against the limiting plate on the second sliding rod and pull the limiting block and limiting ring sequentially to limit the elastic rope, thus separating the limiting assembly from the first sliding rod. At this point, workers only need to pull the first sliding rod to adjust its position. Subsequently, when the distance between the first and second sliding rods matches the spiral wound pipe, workers only need to lower the spiral wound pipe and reset the limiting assembly to stabilize the first sliding rod. This allows the first and second sliding rods to cooperate and limit the spiral wound pipe, reducing the difficulty of operation. Furthermore, workers only need to push the worktable to move the spiral wound pipe to the next process step.

[0008] Furthermore, a fixing groove is provided on the inner wall of the second slide groove, and a fixing block is slidably disposed in the fixing groove, the fixing block being fixed to the second slide rod.

[0009] By adopting the above technical solution, the fixing block reduces the probability of the second slide rod and the second slide groove separating from each other, thereby improving the user experience of the staff.

[0010] Furthermore, a limiting groove is formed on the inner wall of the first slide groove. The limiting component includes a sliding rod slidably disposed in the limiting groove, a compression spring fixed at one end to the side wall of the sliding rod, and a driving device disposed on the worktable for driving the sliding rod. The other end of the compression spring is fixed to the inner wall of the limiting groove.

[0011] Furthermore, the first slide bar has multiple equally spaced limiting holes on its side wall.

[0012] By adopting the above technical solution, when the worker presses the first slide rod and the second slide rod against the two ends of the winding tube respectively, the worker only needs to reset the drive device, which will reset the slide rod under the action of the compression spring, thereby connecting one end of the slide rod with one of the limiting holes, thus blocking the first slide rod, thereby keeping the first slide rod and the second slide rod stable.

[0013] Furthermore, the driving device includes an elastic rope with one end fixed to the sliding rod near the side wall of the compression spring, and a limiting block fixed to the end of the elastic rope.

[0014] Furthermore, a limiting ring is slidably provided on the elastic rope to limit its movement.

[0015] By adopting the above technical solution, when the operator needs to adjust the position of the first sliding rod, the operator only needs to pull the limiting block, which will cause the elastic rope to move with the limiting block, thereby separating the sliding rod from the limiting hole under the action of the elastic rope. Furthermore, the operator only needs to pull the limiting ring, which will block the elastic rope, thus keeping the elastic rope stable. The operator does not need to continuously apply a force to the limiting block to keep it stable, thereby reducing the difficulty of operation.

[0016] Furthermore, a tension spring is fixed to the side wall of the first slide bar near the second slide bar, and the other end of the tension spring is fixed to the inner wall of the first slide groove.

[0017] By adopting the above technical solution, when the sliding rod separates from the first sliding rod and the winding tube separates from the first sliding rod, the first sliding rod moves completely into the first sliding groove under the action of the tension spring, thereby reducing the probability that the first sliding rod will extend out of the first sliding groove at this time, and thus reducing the probability that the first sliding rod will interfere with the operation of other workers at this time.

[0018] Furthermore, a first magnet is provided on the side wall of the second slide bar near the first slide bar, and a second magnet is provided on the inner wall of the second slide groove to attract the first magnet.

[0019] By adopting the above technical solution, when the staff does not need to use the second slide bar, the staff only needs to push the second slide bar to make the first magnet piece and the second magnet piece attract each other, thereby keeping the second slide bar stable and reducing the probability that the second slide bar will move out of the second slide groove at this time.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when workers are producing polyethylene spiral wound pipes, during the initial forming of the spiral wound pipe, they need to cut the pipe and perform subsequent grinding and shaping. At this time, workers need to place the cut spiral wound pipe on a lifting assembly and adjust its height using the lifting assembly. During this process, workers need to pull the second slide rod to move it to its farthest point. Further, workers need to press one end of the spiral wound pipe against the limiting plate on the second slide rod and pull the limiting block and limiting ring sequentially to limit the elastic rope, thus separating the limiting assembly from the first slide rod. At this point, workers only need to pull the first slide rod to adjust its position. Subsequently, when the distance between the first and second slide rods matches the spiral wound pipe, workers only need to lower the spiral wound pipe and reset the limiting assembly to keep the first slide rod stable. This allows the first and second slide rods to cooperate and limit the spiral wound pipe, thereby reducing the difficulty of operation for workers. Furthermore, workers only need to push the worktable to move the spiral wound pipe to the subsequent process.

[0022] 2. In this application, when the worker presses the first slide rod and the second slide rod against the two ends of the winding tube respectively, the worker only needs to reset the drive device, so that the slide rod can be reset under the action of the compression spring, and then one end of the slide rod can be connected to one of the limiting holes, thereby blocking the first slide rod, so that the first slide rod and the second slide rod remain stable.

[0023] 3. In this application, when the operator needs to adjust the position of the first sliding rod, the operator only needs to pull the limiting block to make the elastic rope move with the limiting block, thereby separating the sliding rod from the limiting hole under the action of the elastic rope. Furthermore, the operator only needs to pull the limiting ring to make the limiting ring block block the elastic rope, thereby keeping the elastic rope stable. The operator does not need to continuously apply a force to the limiting block to keep it stable, thus reducing the difficulty of operation for the operator. Attached Figure Description

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-6 As shown in the embodiment of this application, an HDPE polyethylene spiral pipe forming device is disclosed, including a workbench 1, movable wheels 11, support rods 2, top plate 21, lifting assembly 3, first slide rod 4, second slide rod 5, limiting plate 51, limiting assembly 6, fixing block 81, iron ring, magnetic ring, tension spring 84, first magnetic piece 85, and second magnetic piece 9. The movable wheels 11 are disposed on the bottom surface of the workbench 1. The support rod 2 is a rectangular rod structure and is disposed on the upper surface of the workbench 1. The top plate 21 is a rectangular plate structure and is disposed on the support rod 2. The lifting assembly 3 is disposed on the workbench 1 and is used to adjust the height of the spiral pipe. A first sliding groove 31 is formed on one side wall of the workbench 1, and the first slide rod 4 is a rectangular rod structure that slides within the first sliding groove 31. A second sliding groove 41 is formed on the other side wall of the workbench 1, and the second slide rod 5 is a rectangular rod structure that slides within the second sliding groove 41. The limiting plate 51 is a rectangular plate structure. There are two limiting plates 51, which are arranged sequentially on the side walls of the first slide rod 4 and the second slide rod 5 that are far apart from each other.

[0033] A fixing groove 8 is provided on the inner wall of the second slide groove 41. The fixing block 81 is a rectangular block structure. The fixing block 81 is slidably disposed in the fixing groove 8 and is fixed to the second slide rod 5. The fixing block 81 reduces the probability of the second slide rod 5 separating from the second slide groove 41, thereby improving the user experience of the staff.

[0034] A limiting groove 52 is formed on the inner wall of the first slide groove 31. A limiting component 6 is set on the worktable 1 to limit the first slide rod 4. The limiting component 6 includes a sliding rod 61, a compression spring 62, and a driving device 7. The sliding rod 61 is a rectangular rod structure. The sliding rod 61 is slidably set in the limiting groove 52, and multiple equally spaced limiting holes 63 are formed on the side wall of the first slide rod 4. One end of the compression spring 62 is fixed to the side wall of the sliding rod 61, and the other end of the compression spring 62 is fixed to the inner wall of the limiting groove 52.

[0035] When the worker presses the first slide rod 4 and the second slide rod 5 against the two ends of the winding tube respectively, the worker only needs to reset the drive device 7, which will reset the slide rod 61 under the action of the compression spring 62, thereby connecting one end of the slide rod 61 with one of the limiting holes 63, thus blocking the first slide rod 4, thereby keeping the first slide rod 4 and the second slide rod 5 stable.

[0036] A drive unit 7 is mounted on the worktable 1 and is used to drive the sliding rod 61. The drive unit 7 includes an elastic rope 71 and a limiting block 72. One end of the elastic rope 71 is fixed to the side wall of the sliding rod 61 near the compression spring 62. The limiting block 72 is a rectangular block structure, and the limiting block 72 is fixed to the end of the elastic rope 71. The limiting ring 82 is a square annular plate structure, and the limiting ring 82 is slidably mounted on the elastic rope 71 to limit the elastic rope 71.

[0037] When the operator needs to adjust the position of the first sliding rod 4, they only need to pull the limiting block 72, which will cause the elastic rope 71 to move along with the limiting block 72, thereby separating the sliding rod 61 from the limiting hole 63 under the action of the elastic rope 71. Furthermore, the operator only needs to pull the limiting ring 82, which will block the elastic rope 71, thus keeping the elastic rope 71 stable. The operator does not need to continuously apply a force to the limiting block 72 to keep it stable, thereby reducing the difficulty of operation.

[0038] One end of the tension spring 84 is fixed to the side wall of the first slide rod 4 near the second slide rod 5, and the other end of the tension spring 84 is fixed to the inner wall of the first slide groove 31. When the slide rod 61 separates from the first slide rod 4 and the winding tube separates from the first slide rod 4, the first slide rod 4 moves completely into the first slide groove 31 under the action of the tension spring 84, thereby reducing the probability that the first slide rod 4 will extend out of the first slide groove 31 at this time, and thus reducing the probability that the first slide rod 4 will interfere with the operation of other workers.

[0039] The first magnet 85 is a sheet-like structure and is disposed on the side wall of the second slide bar 5 near the first slide bar 4. The second magnet 9 is a sheet-like structure and is disposed on the inner wall of the second slide groove 41, and the second magnet 9 and the first magnet 85 are attracted to each other.

[0040] When the staff does not need to use the second slide bar 5, the staff only needs to push the second slide bar 5 to make the first magnet 85 and the second magnet 9 attract each other, thereby keeping the second slide bar 5 stable and reducing the probability that the second slide bar 5 will move outside the second slide groove 41.

[0041] The operating principle of the HDPE polyethylene spiral wound pipe forming equipment in this embodiment is as follows: When the worker is producing polyethylene spiral wound pipe, during the initial forming of the spiral wound pipe, the worker needs to cut the spiral wound pipe and perform subsequent grinding and shaping work. At this time, the worker needs to place the cut spiral wound pipe on the lifting component 3 and adjust the height of the spiral wound pipe through the lifting component 3. During this process, the worker needs to pull the second slide rod 5 to move the second slide rod 5 to its farthest end. Further, the worker needs to press one end of the spiral wound pipe against the limiting plate 51 on the second slide rod 5, and pull the limiting block 72 and the limiting ring 82 in sequence, so that the limiting ring 82 limits the elastic rope 71, thereby separating the limiting component 6 from the first slide rod 4. At this time, the worker only needs to pull the first slide rod 4 to adjust the position of the first slide rod 4. Subsequently, once the distance between the first slide rod 4 and the second slide rod 5 matches the winding tube, the operator only needs to lower the winding tube and reset the limiting component 6 to stabilize the first slide rod 4. This allows the first slide rod 4 and the second slide rod 5 to cooperate and limit the winding tube, thus reducing the operator's difficulty. Furthermore, the operator only needs to push the worktable 1 to move the winding tube to the subsequent process.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
