With the rapid development of China's economy, more and more cars have entered the family. The rapid increase of cars and the increasing pace of people's life have made fully automatic car washing machines more and more popular among car owners.

Reciprocating car washing machine, also known as gantry reciprocating car washing machine, is also called gantry type car washing machine and gantry machine in China. It is a kind of car washing machine that is widely used at present. When the reciprocating car washing machine is working, the car stops at a fixed position, and the car washing equipment moves back and forth according to the model. Realization: automatic chassis flushing (generally do not turn on the automatic chassis flushing, because some cars with poor quality may damage the car horn), automatic spraying of special car washing liquid and water wax for computer car washing machines, automatic imitation brushing, automatic imitation air-drying . A dirty car goes in and a clean car comes out, and the car wash takes about 3 minutes, which is suitable for car beauty shops and other places with a daily car wash volume of less than 120 cars.

The top brush of the existing car washing machine is to fix two nylon belts at the two ends of the top brush, and the two nylon ropes are respectively wound on two identical circular rollers, and the two rollers are arranged on both sides of the top of the car washing machine. The combination of the reducer and the reducer drives the rotation of the two rollers, and the two rollers drive the top brush up and down by winding and releasing the nylon belt.

However, the motor of the car washing machine should generally use a waterproof motor to ensure reliable operation and longer use time, which leads to high manufacturing costs and inconvenient installation and maintenance of the car washing machine. At the same time, car washing machines usually need to be placed outdoors, so that the motor is completely exposed to the natural environment, so the protection level of the motor is required to be very high. If the performance of the motor is not high, there will be potential safety hazards. If the motor is exposed to the natural environment for a long time, wind and sun will also have a great impact on the life of the motor.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figures 1 and 2, the car washing machine of this embodiment includes a frame 1 and a top brush 2, the top brush 2 is installed on a support bar 3, and the two ends of the support bar 3 are respectively slid on the frame 1, the frame 1 is provided with two sets of lifting drive assemblies for driving the support cross bar 3 to move up and down, and the two sets of lift drive assemblies are arranged close to the two ends of the support cross bar 3 respectively, and each lift drive assembly includes a telescopic cylinder 4, The swing rod 5 and the strap 6, the upper end of the strap 6 is connected with the frame 1, the lower end of the strap 6 is connected with the support cross bar 3, the telescopic cylinder 4 is hingedly installed on the frame 1, and the middle part of the swing rod 5 is hinged on the frame 1 , the piston rod of the telescopic cylinder 4 is hinged with one end of the swing rod 5, and the other end of the swing rod 5 is connected with the sling 6. The telescopic movement of the piston rod of the telescopic cylinder 4 can drive the swing rod 5 to swing back and forth, and then move up and down with the support cross bar 3 and the top brush 2 on it by the strap 6 .

In this embodiment, the sling 6 is a nylon belt. The swing bar 5 is fixedly connected with the sling 6 through a pin buckle. The upper end of the sling 6 is connected to a load limiter 7 fixed on the frame 1, and the load limiter 7 can automatically lock the sling 6 when the lifting drive assembly fails and the top brush 2 drops rapidly. Avoid top brush 2 uncontrolled slide and cause accident.

In this embodiment, the two ends of the frame 1 corresponding to the support bar 3 are respectively provided with a chute arranged along the vertical direction, and the two ends of the support bar 3 are provided with sliders, and each slider is slidably arranged on the Corresponding chute, so that the support cross bar 3 slides back and forth along the vertical direction.

In this embodiment, the telescopic cylinder 4 is connected to the air source through a ventilation pipeline, and a solenoid valve and a throttle valve are arranged on the ventilation pipeline, and the telescopic movement of the telescopic cylinder 4 is controlled by the solenoid valve, and the telescopic movement of the telescopic cylinder 4 is controlled by the throttle valve. The speed of movement can then control the stroke and speed of the top brush 2 moving up and down.

In this embodiment, the telescopic cylinder 4 is installed inside the frame 1, and the telescopic cylinder 4 can be a standard SUS304 material cylinder with a stroke of 500 (for example: AirTAC SE40SUS304x500).

Compared with the original car washing machine, the car washing machine of this embodiment has the following advantages:

1. In the traditional car washing machine, the price of a high-end waterproof motor and the corresponding reducer is about 3,000 yuan; and in the car washing machine of this embodiment, the price of a good cylinder is about 800 yuan. The production cost of the equipment is reduced.

2. Because the car washing machine moves reciprocatingly in the track, when there is a heavy object on the top of the car washing machine, when the car washing machine moves or stops suddenly, the heavy object is easy to loosen and fall, which reduces the safety factor, and the The motor arranged on the upper end of the frame 1 is replaced by the cylinder arranged inside the frame 1, which not only improves the safety level, but also effectively utilizes the internal space of the car washing machine, and can also facilitate the on-site hoisting of the car washing machine.

3. When assembling on site, the installation of the motor and reducer requires the use of a bore crane. The process of lifting heavy objects will increase the risk factor of the installer, and the installation is inconvenient. The installation of the cylinder does not require the use of hoisting equipment, which is not only convenient for installation, but also has a high safety factor.
