Description

Technical Field

[0001] This utility model relates to the field of painting technology for outer steel rings of pipe culvert sockets, and in particular to a painting device for outer steel rings of pipe culvert sockets. Background Technology

[0002] As an important component of pipeline systems, the outer steel ring of a culvert socket primarily enhances the strength and stability of the pipeline. The outer steel ring is a metal ring structure added to the pipeline, especially at the interface of a culvert socket, to strengthen the connection and improve stability. When the pipeline is under pressure or load, the outer steel ring effectively prevents deformation or breakage, ensuring the stable operation of the pipeline system. Particularly in areas with complex geological conditions or insufficient soil bearing capacity, the outer steel ring increases the pipeline's resistance to deformation, preventing displacement or damage caused by external forces. The outer steel ring also protects the pipeline interface, preventing failure due to corrosion, wear, etc. During installation, it is essential to ensure a tight fit between the outer steel ring and the pipeline interface, and to use appropriate fixing methods to ensure it does not fall off or loosen during use. The outer steel ring is a widely used steel structural component. During the production of outer steel rings for culvert sockets, painting is often required to prevent rust after prolonged use.

[0003] Currently, the outer steel ring is usually painted manually. When painting the outer steel ring of a circular or rectangular pipe culvert, it generally requires two coats of epoxy zinc primer and two coats of epoxy asphalt topcoat. Since the steel ring is above the pipe section, uneven paint application and paint dripping from the steel ring onto the concrete pipe wall can occur, affecting the overall appearance quality of the pipe section. The painting speed is also slow, making it inconvenient to paint both the inner and outer rings of the outer steel ring. Utility Model Content

[0004] The purpose of this utility model is to provide a painting device for the outer steel ring of a culvert socket. The first threaded cylinder and the second threaded cylinder are respectively connected to the inlet of the feeding tank. The painting material inside the feeding tank is stored in the cavity, so that the material in the feeding tank can be sprayed through the first painting hole on the second cylinder. This ensures that the first painting head can paint the inner ring of the outer steel ring of the culvert socket placed on the first annular plate, while the arc-shaped painting head paints the outer ring of the outer steel ring of the culvert socket fixed on the second abutment plate.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The first electric push rod 301 is a DC electric push rod of model NKLA22. The telescopic end of the first electric push rod 301 is connected to the first annular plate 3, so that the culvert socket outer steel ring placed on the first annular plate 3 can move up and down.

[0025] The first spray head 4 is movably installed inside the U-shaped plate 1 and the first annular plate 3. A circular ring 302 is set in the internal hole of the first annular plate 3, and the first spray head 4 is fitted inside the circular ring 302. Two side plates 5 are installed on the top surface of the first annular plate 3. A second electric push rod 501 is installed on each of the two side plates 5 by screws. The second electric push rod 501 is a DC electric push rod of model NKLA22. A first abutment plate 502 is installed at the telescopic end of the second electric push rod 501. When the second electric push rod 501 is working, the first abutment plate 502 at the telescopic end of the second electric push rod 501 can fit against the outer ring of the outer steel ring of the pipe culvert socket, so that the outer steel ring of the pipe culvert socket can be fixed on the two side plates 5.

[0026] The first spray head 4 includes a first cylinder 401 and a second cylinder 402. A second annular plate 404 is provided at the top of the first cylinder 401 and the second cylinder 402. A first spray hole 403 is opened on the second cylinder 402. A first conical cylinder 405 is provided at the bottom of the first cylinder 401. A first circular plate 407 is installed at the bottom of the first conical cylinder 405. A second conical cylinder 406 is provided at the bottom of the second cylinder 402. A first threaded cylinder 408 is installed on the second conical cylinder 406. The first cylinder 401 and the second cylinder 402, as well as the first conical cylinder 405 and the second conical cylinder 406, form a cavity. The first threaded cylinder 408 is connected to the inlet of the feeding tank. The paint material inside the feeding tank is stored inside the cavity, so that the material in the feeding tank can be sprayed through the first spray hole 403 on the second cylinder 402. This ensures that the first spray head 4 can spray paint the inner ring of the outer steel ring of the culvert socket placed on the first annular plate 3.

[0027] It also includes a motor base 6, on which a motor is installed. The motor is a brushless DC motor of model JC35W5. A drive gear 601 is installed on the output shaft of the motor. The drive gear 601 meshes with a driven gear 7 on one side. A bearing 701 is set on the top plate 2. The driven gear 7 is installed on the bearing 701. A second circular plate 702 is installed on the inner ring of the bearing 701. An L-shaped plate 703 is installed on the second circular plate 702 by screws. A third electric push rod 704 is installed on the side wall of the L-shaped plate 703. A second abutment 705 is installed on the telescopic end of the third electric push rod 704. The drive gear 601 of the electric output shaft drives the driven gear 7 to rotate, so that the second circular plate 702 on the inner ring of the bearing 701 on the driven gear 7 can rotate, ensuring that the outer steel ring of the pipe socket fixed on the second abutment 705 can rotate.

[0028] An arc-shaped paint spray head 8 is installed on the top plate 2. The arc-shaped paint spray head 8 is connected to a third cylinder 801. A second threaded cylinder 802 is installed on the third cylinder 801. The second threaded cylinder 802 is connected to the feed inlet of the feeding tank, ensuring that the arc-shaped paint spray head 8 can spray paint the outer ring of the outer steel ring of the fixed pipe culvert socket on the second abutment plate 705.

[0029] When using a spray painting device to paint the outer steel ring of the culvert socket, the outer steel ring is placed on the first annular plate 3 of the U-shaped plate 1. The second electric push rod 501 on the side plate 5 is activated, allowing the first abutment plate 502 at the telescopic end of the second electric push rod 501 to fit against the outer ring of the culvert socket, thus fixing the outer steel ring onto the first annular plate 3. The feed inlet of the feeding tank is connected to the first threaded cylinder 408. Activating the first electric push rod 301 on the U-shaped plate 1 allows the first annular plate 3 at the telescopic end of the first electric push rod 301 to move up and down, ensuring that the outer steel ring of the culvert socket on the first annular plate 3 can move. The second electric push rod 501 on the first spray head 4 then moves the outer steel ring. The first paint spray hole 403 of the cylinder 402 can be used to fully paint the inner ring of the outer steel ring of the culvert socket. After the inner ring of the outer steel ring of the culvert socket is painted, the outer steel ring of the culvert socket on the first annular plate 3 is removed and moved to the second circular plate 702. The third electric push rod 704 on one side of the L-shaped plate 703 on the second circular plate 702 is activated so that the second abutment plate 705 at the telescopic end of the third electric push rod 704 can fit against the inner ring of the outer steel ring of the culvert socket. The feed inlet of the feed tank is connected to the third cylinder 801 to ensure that the arc-shaped paint spray head 8 paints the outer ring of the outer steel ring of the culvert socket fixed on the second abutment plate 705, thus completing the overall painting of the outer steel ring of the culvert socket.
