Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile technology, and in particular to an oil spraying device for demolding pipe piles. Background Technology

[0002] With the development of concrete technology, concrete pipe pile technology has become increasingly mature. Besides its application in industrial and civil buildings, it is also widely used in bridges, ports, railways, and water conservancy projects. The production of concrete pipe piles involves processes such as feeding, tensioning, centrifugation, ambient temperature steam curing, release, demolding, and high-pressure steam curing. After demolding, the bottom mold and top mold need to be cleaned and sprayed with release oil.

[0003] When spraying release oil onto the pipe pile mold, a pipe pile release oil spraying device is used. The release agent nozzle in the device moves back and forth to spray the release agent onto the pipe pile mold. Since concrete release oil is generally in the form of a white emulsion, when it is sprayed out through the release agent nozzle, it forms a mist. During the pipe pile production process, this mist of release oil is sprayed onto the inner wall of the arc-shaped pipe pile mold. Part of it adheres to the inner wall of the mold and plays a role in demolding, while the other part diffuses outward. Because the mist of release oil is relatively fine, it is easily disturbed by airflow and thus disperses into the surrounding air, thereby affecting the surrounding air quality.

[0019] 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.

[0020] Reference Figure 1-4An oil spraying device for demolding pipe piles includes a support frame 1, a lifting assembly inside the support frame 1, a movable plate 5 inside the support frame 1 via the lifting assembly, a U-shaped plate 6 fixedly installed on the front side of the movable plate 5, a moving assembly on the top of the movable plate 5, and an L-shaped plate 11 on the front side of the movable plate 5 via the moving assembly. The L-shaped plate 11 is slidably connected to the U-shaped plate 6. The lifting assembly includes a hydraulic push rod 3 and a movable rod 4 disposed inside the support frame 1. The output end of the hydraulic push rod 3 is fixedly connected to the movable plate 5, and the movable rod 4 is slidably connected to the support frame 1 and fixedly connected to the movable plate 5. The lifting assembly facilitates the spraying of oil onto the movable plate 5. The vertical movement provides the driving force, enabling automatic operation. It eliminates the need for manual adjustment of the L-shaped plate 11 and U-shaped plate 6 to cover or move the pipe pile mold, saving labor and time costs. This makes the entire spraying operation of the pipe pile mold smoother and more efficient, reducing equipment downtime and accelerating production. The L-shaped plate 11 contains a spraying assembly, and a ventilation and filtration assembly is located at the front of the L-shaped plate 11. The ventilation and filtration assembly includes a support plate 17 located at the front of the L-shaped plate 11, a filter box 18 fixedly installed on the top of the support plate 17, and a collection pipe 19 fixedly installed at the rear of the filter box 18. The collection pipe 19 is connected to the L-shaped plate 11 for filtration. The filter element 20 is installed inside the filter box 18, and an exhaust fan 21 is fixedly installed on the front side of the filter box 18. After spraying, the exhaust fan 21 is used to extract air from the cavity formed between the U-shaped plate 6 and the L-shaped plate 11, thereby drawing the misty release oil in the cavity into the filter box 18 through the collection pipe 19. The misty release oil is then blocked in the filter box 18 by the filter element 20, achieving effective collection of the release oil scattered in the cavity, preventing the release oil from spreading randomly in the workshop, reducing waste of release oil, and lowering production costs. This oil spraying device for pipe pile demolding, during the spraying process of the pipe pile mold, passes through the U-shaped plate 6 and the L-shaped plate 11. 11 can prevent the mist-like release oil from drifting into the air. This not only avoids the release oil from polluting the air quality in the workshop, but also reduces its potential harm to the health of equipment, tools and workers in the workshop, creating a cleaner and safer space for the production environment. After spraying, as the L-shaped plate 11 moves left and right through the moving component, the mist-like release oil in the cavity formed between the U-shaped plate 6 and the L-shaped plate 11 can be collected through the exhaust filter component. This measure realizes the recycling and reuse of the release oil, reduces production costs, and at the same time further prevents the release oil from spreading disorderly in the workshop, strengthening the protection of the production environment.

[0021] Specifically, the moving component includes a fixed frame 7 located on top of the moving plate 5. A drive motor 8 is fixedly installed on the right side of the fixed frame 7. The output end of the drive motor 8 extends through the fixed frame 7 into the interior of the fixed frame 7 and is fixedly installed with a screw 9. A moving block 10 is threadedly connected to the surface of the screw 9. The moving block 10 is slidably connected to the fixed frame 7 and fixedly connected to the L-shaped plate 11. The moving component facilitates the left and right movement of the L-shaped plate 11, thereby facilitating the operation of the spraying component and the exhaust filtration component. During the spraying process, the movement of the L-shaped plate 11 can cooperate with the spraying component to make the mist-like release oil more evenly cover the inner wall of the pipe pile mold. For the exhaust filtration component, the movement of the L-shaped plate 11 can more effectively collect the scattered mist-like release oil, expand the range of exhaust filtration, collect more release oil, reduce the pollution of the surrounding environment by the release oil, and also facilitate the recycling and reuse of the release oil, thereby reducing production costs.

[0022] Specifically, the spraying assembly includes a storage tank 12 located on top of the L-shaped plate 11. A suction pipe 13 is fixedly installed at the bottom of the storage tank 12. A delivery pump 14 is fixedly installed at the bottom of the suction pipe 13. The delivery pump 14 is fixedly connected to the L-shaped plate 11. A connecting pipe 15 is fixedly installed at the bottom of the delivery pump 14. The bottom of the connecting pipe 15 extends through the L-shaped plate 11 into the interior of the L-shaped plate 11 and is fixedly fitted with a nozzle 16. The spraying assembly facilitates automatic spraying of the inner wall of the pipe pile mold.

[0023] Specifically, a door 22 is provided on the left side of the filter box 18, and a handle 23 is fixedly installed on the left side of the door 22. The door 22 is opened by the handle 23 to facilitate the recovery of the release oil collected inside the filter box 18. Mounting plates 2 are fixedly installed on both the left and right sides of the support frame 1. Mounting holes are provided through the top of the mounting plates 2. The mounting plates 2 can be fixed in a suitable position by bolts through the mounting holes, so as to facilitate the fixation of the support frame 1 and make the device work more stably.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0025] In use: The pipe pile mold is placed under the cavity formed between the U-shaped plate 6 and the L-shaped plate 11. The hydraulic push rod 3 moves the moving plate 5 and the movable rod 4 downward, causing the U-shaped plate 6 and the L-shaped plate 11 to move downward, thus covering the pipe pile mold. Then, the demolding oil in the storage tank 12 is transported from the suction pipe 13 to the connecting pipe 15 by the delivery pump 14, and then sprayed out from the nozzle 16 to spray the inner wall of the pipe pile mold. At the same time, the drive motor 8 rotates the screw 9, causing the moving block 10 to move left and right along the fixed frame 7. Moving to the right causes the L-shaped plate 11 to move left and right, which in turn causes the connecting pipe 15 and the nozzle 16 to move left and right, completing the spraying of the entire inner wall of the pipe pile mold. The U-shaped plate 6 and the L-shaped plate 11 can prevent the mist-like release oil from drifting into the air. After spraying, the exhaust fan 21 can extract the air in the cavity formed between the U-shaped plate 6 and the L-shaped plate 11, thereby drawing the mist-like release oil in the cavity into the filter box 18 through the collection pipe 19. The filter element 20 then blocks the mist-like release oil in the filter box 18.
