Wheel pair paint brushing method

Abstract

The invention relates to a wheel pair paint brushing method. The wheel pair paint brushing method comprises the following steps that S1, a wheel pair is arranged at the top of a rack structure of a wheel pair paint brushing device; S2, a rotating mechanism is started, the rotating mechanism works to drive a first rolling wheel to roll, the wheel pair is driven by the first rolling wheel to rotate,a gap is reserved between the first rolling wheel and a second rolling wheel so as to prevent the wheel pair from deviating, and a rolling mechanism works to drive the wheel pair to rotate; and S3, the paint brushing device is started, the paint brushing device is located below the wheel pair at the moment, and the paint brushing device works to brush paint to the wheel pair. In the method, the rolling mechanism works, the first rolling wheel drives the wheel pair to rotate, the gap is reserved between the first rolling wheel and the second rolling wheel so as to prevent the wheel pair from deviating, the paint brushing device is located below the wheel pair at the moment, the wheel pair constantly rotates at the original position, and therefore the paint brushing device can brush paint to the wheel pair precisely and more evenly, the problems of manual wheel pair pushing and manual paint brushing are avoided, and the paint brushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wheel set painting, in particular to a wheel set painting method. Background technique [0002] The wheel set is the part of the rolling stock that is in contact with the rail. It is composed of two left and right wheels that are firmly pressed on the same axle. The function of the wheel set is to ensure the running and steering of the rolling stock on the rail and withstand All the static and dynamic loads of the vehicle are transmitted to the rails, and the loads caused by uneven lines are transmitted to the parts of the rolling stock. [0003] refer to figure 1 , figure 1 It is a structural schematic diagram of an existing wheel set. The wheel set usually includes a wheel set connecting shaft 1011 and a hub 1012. Both ends of the wheel set connecting shaft 1011 pass through the wheel hub 1012 and extend to the other side of the wheel hub 1012. The shaft 1011 is fixedly connected with the hub 1012 as...

Problems solved by technology

[0004] However, the overhaul workshop in the coal mine does not have special equipment for painting the wheelsets. The painting operation is done entirely by manual hand-held cotton cloths and brushes. The wheel sets are painted, which is labor-intensive and takes no less than ten minutes. According to the production schedule of the existing maintenance workshop, at least 20 wheelsets must be painted every day. task, time-consuming and inefficient

[0005] In addition, employees have to wear heavy gas masks and paint for a long time to contact, which will cause great harm to the health of employees. They also need to clean up the paint on the work site at any time.

[0006] The utility model patent with the application number "CN201520802516.8" discloses a steel pipe straightening, derusting and brushing paint purification device, including straightening device 1, upper wheel, lower wheel, control screw, switch, motor, brush cylinder bearing seat, Brush cylinder, wire brush, straightening device 2, paint brushing device, fuel injection nozzle, oil pump, fuel tank, oil outlet, inlet connection flange, paint mist filter plate, equipment box, inspection door and outlet connection flange, all The steel pipe straightening and derusting painting machine is composed of four parts: a straightening device, a rust removing device, a painting device and a paint mist purifying device. The problem of manually pushing it to rotate

[0007] Another example is that the utility model patent with the application number "CN200720092195.2" discloses a fully automatic vehicle wheel set painting machine, which includes a PLC programming controller and a motor. For the control device, the main painting device is installed in the beam, the end painting device is suspended on both sides of the mast, the wind and electricity pipes are installed on the inside of the frame, and the wheel mechanism and the in and out wheel device are installed on the base; however, in this patent solution, The rotation of the wheel mechanism drives the rotation of the wheel set, which causes the problem of deviation of the wheel set
