And pulling a hand brake after the vehicle is stopped at the parking correct position and the parking position where the 13 red light is lighted is stably stopped. The vehicle washing starting condition is met, and the equipment cannot be started after the vehicle is overtaken. This is a precise positioning guide to prevent scraping the vehicle.
The overhead traveling crane assembly comprises a track beam 9 and an overhead traveling crane 10 arranged on the track beam 9;
a rotating shaft 17 is arranged at one end of the large arm 11, the rotating shaft 17 of the large arm 11 is arranged in the middle of the overhead traveling crane 10, and the large arm 11 is driven to rotate around the circumference of the central axis of the rotating shaft by a rotating stepping motor assembly arranged on the overhead traveling crane 10;
on the crown block 10, a limit switch 19 and a limit switch 20 are respectively arranged on two sides of the rotating shaft 17, and the two limit devices are centrosymmetric about the rotating shaft 17; that is, the proximity switch 19 is on the side of the rotation axis 17, and the proximity switch 20 is a point opposite to the rotation axis 17 with the cantilever rotated 180 ° counterclockwise.
The rotating shaft 17 is provided with a small rotating iron plate 18 for triggering the limiting device, and when the small rotating iron plate 18 is positioned at a proximity switch 19 or a proximity switch 20, the proximity switch acts correspondingly.
An ultrasonic detection device 21 is arranged in front of the crown block 10.
Still include walking step motor subassembly.
The walking stepping motor assembly comprises a walking stepping motor 7, a stepping servo driver 2 electrically connected with the walking stepping motor and an encoder 4 arranged on the walking stepping motor;
the rotary stepping motor assembly comprises a rotary stepping motor 8, a stepping servo driver 2 electrically connected with the rotary stepping motor and an encoder 4 installed on the rotary stepping motor.
The device is characterized by further comprising a PLC (programmable logic controller) 1, wherein the PLC 1 is electrically connected with the rotary stepping motor assembly, the limit switch 19, the limit switch 20, the walking stepping motor assembly and the guiding parking control assembly 3 respectively.
The large arm 11 is of an L-shaped structure formed by welding stainless steel square steel, and a nozzle is arranged on the large arm 11.
The outer surface of the large arm 11 is provided with a rubber heat-insulating cotton layer 6, and a heat-shrinkable tube 5 is sleeved on the rubber heat-insulating cotton layer.
The crown block 10 is allowed to move linearly along the rail 9 only when the rotating shaft 17 and the rotating shaft 17 give a signal to the point proximity switch. And the overhead traveling crane 10 initial point installation overhead traveling crane initial point proximity switch 19, the overhead traveling crane 10 initial point and rotation axis 17 are satisfied simultaneously, and equipment can not start the operation, prevents to scrape the car. After the starting condition is met, the cantilever rotates anticlockwise until the large arm 11 stops at the point-to-point approach switch 20 along the cantilever track 22, and then the crown block 10 is allowed to do linear motion towards the tail direction of the vehicle; when the tail of the vehicle is detected by ultrasonic waves 21 (positioning detection parking space position) in front of the crown block, the crown block 10 stops, then the large arm 11 rotates anticlockwise to the cantilever origin point near switch 19 to stop, then the crown block 10 makes linear motion towards the direction of the head of the vehicle to return to the origin point (starting point) of the crown block to stop, and the motion of one circle is completed. Therefore, each step is interlocked, and the vehicle is prevented from being scraped.
The rotation of the large arm 11 and the walking of the overhead traveling crane 10 are controlled by the output pulse of the plc programmable controller 1 to control the speed and direction. If the overhead traveling crane 10 and the cantilever 11 are scratched in the running process, the encoder 4 of the stepping motor outputs a high-speed pulse signal to change, and the signal is transmitted back to the driver; and data are collected in real time and compared with set parameters, and then the difference is transmitted to the plc programmable controller 1 for operation (ms).
And designing an editing application program, and editing program codes according to the variable quantity of the acquired data to output and control the stop of the operation of the stepping motor. The control sensitivity can be improved by adjusting the data parameters, and the data parameters are finely adjusted according to actual conditions. Thus, the plc output stops when the large-arm rubber heat-insulating cotton is slightly stopped after being attached to the surface of the vehicle at the moment of scraping.
