Leveling device for automobile test ramp gravel

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...

AI Technical Summary

Problems solved by technology

[0003] But there are two disadvantages of this method: first, it takes up a tractor, and it is troublesome to install and operate every time.

Second, only relying on the weight of the scraper to level the gravel on the slope, the leveling accuracy is not enough, and it may take multiple levels to achieve the leveling accuracy requirements, which is time-consuming and laborious

But there is no mention of how to level the gravel of the car test ramp
