Description

Technical Field

[0001] This utility model relates to the field of guardrail processing technology, specifically to an electrostatic spraying box for guardrail processing. Background Technology

[0002] Guardrails play a vital role in modern infrastructure construction and daily life. Whether it is protecting residents' safety around their homes, protecting passing vehicles and pedestrians on highways, or maintaining order and protecting equipment and facilities in commercial areas and public places, guardrails are indispensable. To extend the service life of guardrails and improve their aesthetics, electrostatic spraying has become a key step in guardrail processing. Electrostatic spraying uses an electric field to make negatively charged paint particles evenly adhere to the positively charged surface of the guardrail workpiece, forming a paint film to achieve rust and corrosion prevention as well as beautification.

[0003] However, current electrostatic spraying boxes for road construction guardrail processing have significant drawbacks in practical applications. For example, in one disclosed electrostatic spraying box (CN219923339U), the spraying components are fixed in position. When spraying guardrail workpieces of varying shapes and sizes, it is difficult to achieve uniform coverage of the paint in all directions. In some areas, due to improper spraying distance, angle deviation, or other factors, the paint may be sprayed too thickly or too thinly. Excessive paint thickness can easily lead to drips, wasting paint. It also seriously affects the appearance and protective performance of the guardrail; if it is too thin, it cannot effectively prevent rust and corrosion. Similarly, an electrostatic spraying box (CN216654995U) for road construction guardrail processing also has the problem of poor adjustability of the spraying components. It is difficult to adjust the position according to the structural characteristics of different guardrails and cannot meet the diverse spraying needs. This not only reduces the spraying quality and increases the defect rate, but may also lead to subsequent rework, prolong the processing cycle and increase the production cost. Therefore, we have proposed an electrostatic spraying box for guardrail processing. Utility Model Content

[0033] Structural Description:

[0034] Working support frame 1: As the basic support structure of the entire equipment, it supports and fixes other components. Its inner bottom surface is used to install the rotary drive motor 7, motor support platform 15, and collection box 12, and provides a rotation connection point for the active support wheel 8; the inner side is fixed to the water pump support platform 14; the top surface is used to fix the liquid storage tank 5 and the moving drive motor 2; and the top is fixed to the top support platform 16, providing a stable working platform for the entire spraying operation.

[0035] Rotary drive motor 7: The rotary drive motor is mounted on the motor support platform and is the core of the power for the rotation of the guardrail. It transmits power through the output shaft to drive the active support wheel to rotate. The motor has appropriate power and torque to ensure that it can stably drive the guardrail to rotate during the spraying process and achieve all-round uniform spraying.

[0036] Motor support platform 15: The motor support platform is fixed to the bottom of the working support frame. It is usually a plate structure made of metal. Its shape and size are adapted to the rotating drive motor. It is connected by welding or bolts to provide stable support for the motor, disperse the vibration of the motor during operation, and ensure the stable operation of the motor.

[0037] Active support wheel 8: The active support wheel is rotatably connected to the bottom of the working support frame through a bearing. The mounting groove on the side is used to install the guardrail clamping assembly. Driven by the rotation drive motor, the active support wheel rotates to provide rotational support for the clamped guardrail, so that the guardrail is evenly coated with paint during spraying.

[0038] Clamping drive cylinder 9: The clamping drive cylinders are evenly distributed on the inner side of the mounting groove on the side of the active support wheel. It is the power component for clamping the guardrail. It uses compressed air to drive the piston rod, that is, the clamping sliding rod, to extend and retract. By controlling the air pressure, the clamping force can be adjusted to meet the clamping requirements of guardrails of different sizes.

[0039] Clamping sliding rod 10: The inner side of the clamping sliding rod is connected to the piston rod of the clamping drive cylinder, and the outer end is fixed to the clamping slider. Under the push of the cylinder, it slides along a specific track, transmitting the thrust of the cylinder to the clamping slider to achieve precise clamping and releasing of the guardrail, ensuring the stability of the guardrail during spraying.

[0040] Clamping slider 11: The clamping slider slides in the mounting groove on the side of the active support wheel. The inner side is used to fix the guardrail. It fits tightly with the mounting groove and slides smoothly. It is connected to the guardrail by bolts or clamps. Under the push of the clamping slider rod, it reliably clamps the guardrail and prevents it from shaking during spraying.

[0041] Storage tank 5: The storage tank is fixed on the top surface of the working support frame and is a container for storing paint liquid. It is mostly made of corrosion-resistant materials. Its bottom surface is equipped with a transfer pipe interface, and its top surface has a liquid injection port and a vent hole. The liquid injection port is used to add paint liquid, and the vent hole balances the air pressure inside the tank to ensure that the paint liquid flows out smoothly.

[0042] Adaptor pipe 18: One end of the adapter pipe is connected to the bottom of the liquid storage tank, and the other end is connected to the drive water pump. It adopts a sealed connection to prevent paint leakage. Its pipe diameter is designed according to the paint flow requirements, so that the paint in the liquid storage tank can flow smoothly into the drive water pump, providing a stable supply of paint for spraying.

[0043] Drive water pump 19: The drive water pump is fixed on the water pump support platform and is the power source of the spraying assembly. It draws paint from the storage tank and pressurizes it, and delivers it to the spray head through the delivery hose. The power and head of the water pump are selected according to the spraying requirements to ensure that the paint can be sprayed evenly.

[0044] Infusion tubing 20: The infusion tubing connects the drive pump and the spray head. It is made of flexible and corrosion-resistant material. Its smooth interior reduces the resistance to paint delivery and its flexibility allows it to adapt to the movement of the spray head and stably deliver pressurized paint to the spray head.

[0045] Spray head 21: The spray head is fixed on the bottom surface of the sliding support platform and is a key component for spraying. Its spray head has a special structure and can be fan-shaped or round, etc., depending on the spraying requirements. It can make the paint evenly sprayed on the surface of the guardrail to form a uniform paint film.

[0046] Top support platform 16: The top support platform is fixed on the top of the working support frame, providing support and movement space for the top spraying moving component. Its internal top surface has guide rails or grooves to guide the movement of the sliding support platform. A drive shaft is installed on the inner side to ensure that all components work together.

[0047] Mobile drive motor 2: The mobile drive motor is fixed on the top surface of the working support frame and provides power for the movement of the spray head. Its output shaft is connected to the transmission shaft, and the operation drives the transmission shaft to rotate, thereby driving the transmission belt and the sliding support platform to realize the adjustment of the spray head position.

[0048] Transmission belt 3: The transmission belt is sleeved on the outside of the transmission shaft and is frictionally connected to the transmission shaft to transmit power. A sliding support platform is fixed on its outside. When the transmission shaft rotates, the transmission belt drives the sliding support platform to move, thereby realizing the movement of the spray head within the top support platform to ensure uniform spraying.

[0049] Drive shaft 6: The drive shaft rotates inside the top support platform and is mounted with bearings. It rotates flexibly. Its length and diameter are designed according to the equipment. It has a special texture on its surface and fits tightly with the drive belt to effectively transmit the power of the moving drive motor.

[0050] Sliding support platform 17: The sliding support platform slides on the top surface inside the top support platform, and the spray head is fixed on the bottom surface. It works well with the top support platform and moves smoothly under the drive of the transmission belt, accurately adjusting the position of the spray head to meet the spraying requirements of different guardrails.

[0051] Working Principle: When this utility model is needed, the guardrail to be sprayed is placed inside the active support wheel 8. The clamping drive cylinder 9 is activated, and the cylinder pushes the clamping sliding rod 10 to slide inside it. The clamping slider 11, which is fixed at the outer end of the clamping sliding rod 10, slides in the mounting groove on the side of the active support wheel 8 until the guardrail is clamped, ensuring its stable position during spraying. The rotation drive motor 7 is mounted on the motor support platform 15, which is fixed to the bottom surface inside the working support frame 1. After the rotation drive motor 7 is started, its output shaft drives the active support wheel 8 to rotate. Since the guardrail has been fixed by the clamping slider 11, the guardrail rotates together with the active support wheel 8, creating conditions for all-round spraying. At the same time, the liquid storage tank 5 on the top surface of the working support frame 1 stores the paint. The drive water pump 19 is fixed on the water pump support platform 14, which is located inside the working support frame 1. The drive water pump 19 is started, and the liquid storage tank is connected to the adapter pipe 18. The paint in step 5 is extracted and delivered to the spray head 21 via the infusion hose 20. The spray head 21 is fixed to the bottom surface of the sliding support platform 17. The paint is sprayed from the spray head 21 to coat the rotating guardrail below. The moving drive motor 2 is fixed to the top surface of the working support frame 1. Its output shaft drives the transmission shaft 6 to rotate. The transmission shaft 6 rotates inside the top support platform 16, and the transmission belt 3 is frictionally connected to the outside of the transmission shaft 6. The sliding support platform 17 is fixed to the outside of the transmission belt 3. The sliding support platform 17 slides inside the top surface of the top support platform 16. In this way, when the moving drive motor 2 is running, it drives the sliding support platform 17 to move through the transmission belt 3, which in turn drives the spray head 21 to move. The spraying position can be adjusted according to the shape and size of the guardrail to achieve uniform spraying. During the spraying process, the paint that does not adhere to the guardrail will fall off. The collection box 12 fixed inside the bottom surface of the working support frame 1 can collect this paint for subsequent processing, avoiding paint waste and environmental pollution.
