1. Product introduction
The multi-functional tunnel (sound insulation screen) cleaning vehicle is a product carefully designed and developed by the company in digesting and absorbing the advanced technology of similar foreign products, combined with the specific situation of China's highway tunnels. The equipment has the characteristics of easy operation, flexible action, wide range of optional devices, reliable quality, high cleaning efficiency and good cleaning effect, and is an ideal product for highway tunnel cleaning. Since the advent of this series of products, it has been favored by many domestic customers. It is suitable for sprinkler trucks, sweepers, and high-pressure cleaning vehicles, and the installation does not affect the licensing and annual inspection, and the disassembly is convenient and fast.
Second, the working principle
The multi-functional tunnel wall (sound insulation screen) cleaning vehicle adopts the self-developed power take-off as the power take-off to drive the hydraulic pump, and the hydraulic flow and pressure output from the hydraulic pump pass through the distribution valve, and reach the cylinder and the hydraulic motor to control the rotation and lifting of the cleaning arm respectively, the cleaning of the roller brush, the water spray of the high-pressure water gun and the lifting action of the scissor hydraulic lifting platform, and complete the cleaning of guardrails, road signs and toll sheds on both sides of the highway or municipal road, and the scissor hydraulic lifting platform can realize the function of a small aerial work vehicle.
3. The main advantages of the multi-functional tunnel wall (sound insulation screen) cleaning vehicle
Compared with the twin engines of other manufacturers on the market, the multi-functional tunnel wall (sound insulation screen) cleaning vehicle not only has the characteristics of low cost and less failure rate, but also has unique advantages in its cleaning effect. First of all, the take-off force of the actuator comes from the engine of the car, so as long as the engine is started and the vehicle is stationary, the cleaning mechanism can also work to achieve fixed-point operation. Equipped with LST-8 speed regulating gearbox and harmonic frequency conversion mechanism, the maximum speed can reach 8 gears during operation, so that its working speed can reach a minimum of three kilometers per hour, and the maximum speed of its cleaning brush can reach 450 rpm, and the vehicle with the auxiliary engine wants to reach 3 kilometers per hour, the operator needs to continuously step on the clutch to achieve, in this way, the result of the wear of the clutch plate can be imagined. When the vehicle's engine fails to start, the operator can activate the backup power unit and operate the cleaning arm and other devices to the appropriate position to complete the engine overhaul.
Regarding the cleaning effect, the multi-functional tunnel wall (sound insulation screen) cleaning vehicle uses high-grade imported cotton polished plastic brush filament with high friction coefficient and high water absorption, which replaces the smooth and wear-resistant nylon filament and detergent, which not only improves the cleaning effect greatly, but also makes the operation process more energy-saving and more environmentally friendly.
1.The cleaning arm can be rotated left and right, and the cleaning height can be adjusted up and down, so that it is convenient to clean the walls on both sides of the tunnel, and the cleaning range is large.
2.The water tank of the water wheel is used as the water storage tank, which can ensure the cleaning of long mileage, and the pressure and flow of the water can be adjusted.
3.It is not equipped with an auxiliary engine as the power, which increases the load capacity of the water tank, which can reach about 12 cubic meters at most, and can continue to work for a long time and effectively improve work efficiency. It effectively saves the cost of use and reduces the failure rate.
4.The bristles are made of polyethylene ultra-soft material, which has the characteristics of high water absorption, large rubbing force and strong elongation, which ensures that the bristles are cleaned and not easy to damage the bristles and working surface.
