[0049] Specific implementation method

[0050] The present invention will be further described below in conjunction with the drawings.

[0051] See Figure 1 to Figure 11 , A leveling device for the rubble of an automobile test ramp is shown, including a traction mechanism at both ends of the transverse groove 31 at the top of the test ramp 3, a track 4 set on the test ramp 3, and a track 4 On the upper leveling scraper trolley, the lower end of the track 4 is provided with a downward bending section 41, and the lower end of the track is bent into a downward bending section. When the scraper descends to the lower end of the track, there is a larger descending range, so that the road surface adjacent to the test ramp forms a small slope, which is convenient for the test car to drive into the test ramp. Its outstanding substantive features are:

[0052] The traction mechanism includes a drive motor 1 arranged in one end of the transverse groove 31, a reducer 11 matingly connected to...

Abstract

The invention relates to a leveling device for automobile test ramp gravel. The leveling device comprises traction mechanisms arranged at the two ends of a cross groove in the top of a test ramp, rails arranged on the test ramp, and a leveling scraper blade trolley arranged on the rails. The traction mechanisms comprise drive motors arranged in one end of the cross groove, speed reducers cooperatively connected to the output ends of the drive motors, and long transmission shafts with one ends coaxially connected with the output ends of the speed reducers, and the long transmission shafts penetrate through the cross groove. Transmission gears are arranged at the two ends of the long transmission shafts respectively. The leveling device further comprises two sets of winding parts arranged onone sides of the two ends of the cross groove respectively, and middle gears of the two sets of winding parts are engaged with the transmission gears at the two ends of the long transmission shafts respectively. The other ends of mooring ropes of the two sets of winding parts are connected with the leveling scraper blade trolley arranged on the rails respectively. The automobile test ramp gravelcan be rapidly leveled, and it is guaranteed that the leveling precision meets the requirements. The test result is precise and reliable, the safety and the reliability are achieved, and time and labor are saved.

Description

technical field [0001] The invention relates to an automobile road test, in particular to a leveling device for crushed stones on an automobile test slope. technical background [0002] In the automobile comprehensive test field, there are many kinds of simulated test roads, one of which is a simulated test road with a gravel ramp. The roads feature gravel-covered hardened ramps designed to simulate the car's handling when climbing hills. When the car climbs a slope, the wheels will throw back the gravel scattered on the road, and the gravel will roll down the ramp and accumulate in the lower part of the ramp, while the upper part of the ramp lacks gravel. As a result, the function of the simulated lane is lost. For addressing this problem, at present, people's way is to use a scraper, under the drive of traction car, the gravel that rolls is scraped and relaid on the ramp. [0003] But this approach has two disadvantages: first, it occupies a tractor, and it is troubleso...
