Detailed Description

As shown in fig. 1, the parking accuracy measuring device for the test run wire passenger car disclosed in this embodiment includes an on-vehicle mechanism 1 and an off-vehicle mechanism 2, which are used in a matching manner, and the on-vehicle mechanism emits laser light onto the off-vehicle mechanism to measure a parking position.

As shown in fig. 2, the onboard mechanism 1 includes a mount 11 and a laser transmitter 12. Wherein the mounting seat 11 comprises a bottom plate 111 and a pair of vertical plates 112; the bottom plate 111 is a rectangular plate, and mounting holes are formed in four corners of the bottom plate for assembling with the cab 3; the vertical plate 112 is a rectangular plate vertically welded on the bottom plate, a pair of through holes are arranged on the vertical plate, adjusting nuts 113 and matched adjusting bolts 114 are welded outside the through holes, and the pair of vertical plates are symmetrically arranged about the central plane of the bottom plate in the width direction. Laser generator 12 chooses for use the laser pen, arranges the width direction center of bottom plate in with the laser pen during assembly, then twists each adjusting bolt and withstands the laser pen, accomplishes preliminary location, treats that the laser pen presss from both sides tight laser pen with each adjusting bolt of screwing up again after mechanism 2 calibration under the car.

As shown in fig. 3 and 4, the under-vehicle mechanism 2 includes a pole unit 21 and a parking accuracy rule 22. The holding pole assembly 21 comprises a fixing plate 211, a U-shaped bolt 212 and a connecting plate 213; the fixed plate is rectangular plate, and four corners is equipped with the slotted hole on it, and the slotted hole carries out position control when U type bolt hugs closely the iron set of being convenient for, is convenient for adjust to the zero scale mark of laser pen and parking precision chi and adjusts well, and a pair of U type bolt is upper and lower to be set up, and the open end passes corresponding slotted hole respectively, and three connecting plate is vertical arranges, connects between two U type bolts. The parking precision ruler 22 is a middle dividing ruler, the parking precision ruler is connected outside the fixed plate, zero graduation lines are aligned with the width direction center plane of the fixed plate, and when the distance between a parking position and a designated position is larger than 50CM during measurement, scoring is not performed, so that the measurement lengths of two ends of the selected middle dividing ruler are both 50 CM. The mechanism under the car is connected on the outer iron set 4 of track through the supporting corresponding nut of U type bolt, and the calibration is just projected on the zero scale mark of parking precision chi when locking to the laser that the laser pen sent.
