Detailed Description

The embodiment of the invention provides a slope braking strength detection device for second-hand vehicle identification, which comprises a platform 1, wherein an inclined plate 2 is hinged to the right end of the platform 1, and the inclined plate 2 is obliquely arranged, as shown in figures 1-6. The left side welding of 1 bottom of platform has support frame 3, and 1 top pin joint of platform has a plurality of cylinders 11, and cylinder 11 transverse arrangement. The car is brought onto the platform 1 with the wheels in contact with the rollers 11. The wheels of the vehicle are started to rotate between the rollers 11, so that the vehicle reaches a preset speed before detection. And the length of the whole platform 1 is 150 meters, and the roller 11 is positioned at the back, thereby reserving the run-up distance on the platform 1.

Two ends of the roller 11 respectively penetrate through the front side and the rear side of the platform 1, gears 111 are welded at the end parts of the roller 11, and two adjacent gears 111 are meshed with each other. The front end and the rear end of the platform 1 are both connected with an electric push rod 12, and the electric push rod 12 can extend to clamp the gear 111. When the electric push rod 12 extends to block one of the gears 111, all the rollers 11 are locked and can not rotate, and the automobile runs forwards. The automobile runs to the inclined plate 2 for braking. And recording the braking distance of the automobile by the detection personnel. The braking effect of the vehicle on a dry slope is then detected.

A plurality of recesses 21 have been seted up at 2 tops of swash plate, and fixed mounting has nozzle 4 in the recess 21, and water tank 5 has been placed to 2 below of swash plate, and fixed mounting has a plurality of water pumps 6 in the water tank 5, and water pump 6 and recess 21 one-to-one, 6 upper end intercommunications of water pump have water pipe 61, and swash plate 2 and nozzle 4 intercommunication are passed to water pipe 61 upper end.

The water in the water tank 5 is sprayed from the nozzle 4 by the water pump 6. The water flows down along the sloping plate 2, and the sloping plate 2 simulates the road surface of the rainy day by continuous water spraying.

The front side of the water tank 5 is pivoted with a cross rod 51, and the cross rod 51 is in transmission connection with one gear 111. The cross rod 51 stretches into the water tank 5 and is welded with the connecting plate 8 with a hollow interior, the rear side of the water tank 5 is fixedly provided with the funnel 7, and the funnel 7 stretches into the water tank 5 and is communicated with the connecting plate 8. Two ends of the connecting plate 8 are located on the same axis, an outlet hole 81 is formed in one side of the connecting plate 8, a blocking piece 82 is hinged in the outlet hole 81, and the movable end of the blocking piece 82 extends out of the connecting plate 8, so that the blocking piece 82 can only move in the direction away from the connecting plate 8. The connecting plate 8 is filled with sand and stones. When the baffle plate 82 is turned over, the outlet hole 81 is unblocked, so that sand and stones in the connecting plate 8 fall out.

The lower end of the funnel 7 extends into the water tank 5 and is welded with a connecting pipe 71, and the lower end of the connecting pipe 71 inclines downwards and is pivoted with the connecting plate 8. The lower end of the connecting pipe 71 is coaxial with the cross bar 51. Accordingly, the end of the link plate 8 and the lower end of the link pipe 71 are coaxial with the cross bar 51, and the link plate 8 can rotate around the axis following the cross bar 51.

The top of the funnel 7 is connected with a top cover 72 in a threaded mode. When the device works, sand and stones are poured into the funnel 7 and enter the connecting plate 8 along the connecting pipe 71. The automobile wheel drives the roller 11 to rotate, so that the cross rod 51 drives the connecting plate 8 to rotate around the shaft, and when the outlet 81 faces downwards, the blocking piece 82 is opened to allow sand and stones to leak out. Then the water pump 6 delivers the water flow carrying sand and stones to the water pipe 61 and sprays the water flow onto the inclined plate 2 from the nozzle 4, after the road surface is wet, the water pump 6 stops delivering, and part of the sand and stones remain on the inclined plate 2. Thereby simulating a multi-stone sub-road section of the mountain road after rain.

And the spraying of the sand and stone is synchronously carried out with the starting and accelerating of the automobile. Thereby saving time, simplifying the operation and saving unnecessary operation.

The outer side of the water tank 5 is provided with a belt 15, one gear 111 is welded with a bulge 14, and the cross rod 51 is in transmission connection with the bulge 14 through the belt 15.

Part of the water flows from the grooves 21 into the extension grooves 22 and then flows downward from the extension grooves 22, so that the water is uniformly distributed on the inclined plate 2. The uneven dryness and the uneven wetness of the sloping plate 2 are avoided.

The slot 23 has been seted up to side symmetry around the swash plate 2 top, and the kerve 231 has been seted up at swash plate 2 top, and the kerve 231 tip communicates with the 23 lower extremes of slot. A leak hole 24 is arranged in the bottom groove 231, and a collecting groove 10 is arranged below the inclined plate 2 relative to the leak hole 24.

Through the cooperation of bottom slot 231, slot 23, small opening 24, play the effect of recovery water and gravel and sand.

The support frame 3 is composed of a base 31, a steel frame 32 and a bolt 33, the upper end of the steel frame 32 is welded with the bottom of the platform 1, the lower end of the steel frame 32 is inserted into the top of the base 31, the bolt 33 penetrates through the base 31 and the steel frame 32, and the bolt 33 is in threaded connection with the base 31 and the steel frame 32.

A protective frame 13 is fixedly arranged at the top of the platform 1, and the protective frame 13 is used for protecting an automobile.

The front side and the rear side of the inclined plate 2 are respectively and fixedly provided with a frame 9, and the frame 9 is fixedly provided with a protective net 91. The automobile protection device also plays a role in protecting the automobile.

In summary, the slope braking strength detection device for the second-hand vehicle identification detects the braking strength of the vehicle on the common road section by combining the platform 1 and the inclined plate 2.
