The process can be divided into three processes according to actual needs:
the movement between two measuring points of the Beckman beam is realized by arranging the platform truck 100, carrying the Beckman beam on the platform truck 100 and driving the platform truck 100 by means of the traction rope 900 and the loading truck 600.
The loading vehicle 600 stops when reaching the measuring point position, a Beckman beam measuring head is arranged on the measuring point (30-50) mm in front of the center of the wheel gap, a groove is arranged on the platform vehicle to fix the distance between the Beckman beam bases so as to adjust the relative distance between the two Beckman beams to be equal to the distance between the two rear wheels of the loading vehicle 600 in terms of mechanical principle, meanwhile, two inclined first sliding grooves 620 are arranged at the tail of the loading vehicle 600, through a transverse positioning rod 700, the fact that the front end of the Beckman beam does not touch the tire when entering the wheel space is ensured, according to different projects and different distance changes of the two rear wheels of the loading vehicle 600, the two Beckman beams can be simultaneously inserted into the rear wheels, and by means of the positioning principle of the sliding grooves, the change of the upper degree of freedom, the upper degree, the lower degree, the front degree and the rear degree of freedom can be consistent with the advancing direction of the loading vehicle 600 and can be accurately inserted into the rear wheels. At this time, the transverse positioning rod 700, the connecting rod 800 and the sliding portion 310 are rigidly connected, the loading vehicle 600 suddenly stops, the platform vehicle 100 drives the beckman beam 200 to move forward continuously due to inertia effect on the premise of lacking braking, the sliding portion 310 starts sliding and drives the fixed inclined strut 400 to separate from the limiting groove 210, the beckman beam 200 falls to the ground and brakes the platform vehicle 100 under the lack of supporting effect, and the beckman beam measuring head can be placed at a measuring point (30-50) mm in front of the wheel gap center by adjusting the front-back distance of the limiting groove and the length of the second sliding groove 330.
After the loading vehicle is started to be driven out of a deflection influence range, which is generally more than 3m, the Beckman beam keeps in situ and is not touched by the vehicle, after the loading vehicle is driven out of the deflection influence range of a measuring point, the front end of the Beckman beam gradually and automatically rises, the Beckman beam moves along with the vehicle by depending on a platform at the rear end of the beam, the first gear and the rotating gear are separated when the loading vehicle reaches the position of the measuring point, the sliding block 340 is far away from the first gear, therefore, the wire take-up pulley 320 can freely rotate, and the automatic wire paying-off in the step 3 can be realized by the rotating and paying-off process of the traction rope wire take-up pulley. And, set up the second runner 330 in the centre of the platform truck 100, there are slide blocks 340 in the middle of the runner, can slip forward and backward, make up the sliding part 310, the middle perpendicular platform truck 100 travel direction of the slide block 340, there are horizontal shafts 500, there are oblique brace rods 400 at both sides of horizontal shaft 500, set up the spacing groove 210 in the Bakelman roof beam 200 close to platform truck 100, through moving forward, drive the slide block on the platform truck to move along the second runner, move to the second runner terminal position on the platform truck 100, the oblique brace rod enters the spacing groove of the Bakelman roof beam 200, and then make the Bakelman roof beam 200 rise and keep stable, after reaching the measuring point, the vehicle stops, the connecting rod 800 pushes the slide block 330 backward, the forward stroke leads to the oblique brace rod to disengage the spacing groove under the inertia of the platform truck, the front end of the Bakelman roof beam drops in the front end of the rear double wheel 3-5cm automatically.
