The guide rail 513 selected in the invention is HGH15, and the slide block is HGH15CA10.
The principle of operation of the side drive 5 is as follows:
the side driving device 5 is a main device for standardizing and guiding the movement of the cleaning and sampling platform 3 and the spreader platform 2, and determines the movement speed and the movement position of the cleaning and sampling platform 3 and the spreader platform 2. The side drive 5 is functionally roughly divided into: a fixed part (side drive frame 51), a drive part (side drive block assembly 52 of the washing and distributing machine platform 2) and a follow-up part (organ cover assembly 53, drag chain assembly 54). The fixing part supports and fixes each part of the side device, the driving part is an active part, the driving guide cleaning and sampling platform 3 and the spreader platform 2 move, and the follow-up part moves along with the driving part.
The frame extending out of one side of the cleaning and sampling platform 3 and the spreader platform 2 is connected with a side driving device driving block assembly 52 through a bearing seat assembly. The shaft 72 and the bearing seat 7 cooperate to enable the two vehicles to rotate around the side edge in a driving way, and the angle is self-adjusted in the X and Y directions according to the flatness of the pavement in operation, and the adjustment range is +/-3 degrees.
The side driving support frame 511 is fixed to the ground by expansion bolts, and two guide rails 513 and one rack 512 are installed on the support frame 511. The side driving block assembly 52 of the cleaning and sampling platform 3 and the spreader platform 2 is fixed on a slide block mounting plate 525 by a motor 521, a reducer 522 and a bearing seat 7, the output end of the reducer 522 is connected with a gear 523, and the other side of the mounting plate 525 is mounted on a guide rail 513 by a slide block 524. During operation, the motor 521 on the driving block assembly 52 rotates, after the speed reducer 522 decelerates and increases the torque, the preset torque and the rotation speed are output to the gear 523, so that the gear 523 is meshed with the rack 512 to generate thrust, and the driving part of the two vehicles is driven to slide along the guide rail 513, so that the cleaning and sampling platform 3 and the spreader platform 2 are guided to move. The laser range finder corrects the moving gesture of the two vehicles in real time, so that the moving speed of the driving wheels of the cleaning and sampling platform 3 and the distributing machine platform 2 is consistent with that of the side driving block assemblies 52 of the cleaning and sampling platform 3 and the distributing machine platform 2.
The preset program controls the rotating speed of the motor, changes the meshing speed of the gear and the rack, further controls the moving speed of the driving block assembly 52, and divides the motion process of the cleaning and sampling platform 3 into an acceleration section, a uniform speed section and a deceleration section. The working process of the spreader platform 2 is also same as that of the cleaning and sampling platform 3, and is controlled by a preset program to be divided into three stages of acceleration, uniform speed and deceleration. The uniform speed section of the spreader platform 2 is the most uniform area of the spreader, so the test sampling area is between the sections.
The fixed end of the drag chain 54 is fixed in the sheet metal groove on the top surface of the side support frame, and the movable end is fixedly connected to the driving block assembly 52 through the end plate and moves along with the movement of the driving block assembly 52. The organ cover 53 is fixed between the two car driving block components, and compresses or stretches along with the movement of the two sliding ends, so as to protect the two guide rails 513 and the rack 512 from being worn by dust and sand.
After the work is completed, the sliding end guides the cleaning and sampling platform 3 and the spreader platform 2 to move to the two ends of the side device. When the two platforms run to the limit positions at the two ends, the travel switches are arranged at the limit positions at the two ends on the support frame 511, the slide block mounting plates 525 of the side driving components touch the travel switches, so that the two vehicles stop moving and are stopped at the limit block, and then the two vehicles are rotated for 90 degrees to retract.
