Before the verification method in the present invention is introduced in detail, at first introduce the plate type brake test platform in the prior art, the plate type brake test platform includes a base body 5 and a pair of front wheels 2 for manufacturing a car. A front brake bench 11 for dynamic inspection and a pair of rear brake benches 12 for performing brake inspection on the rear wheels of the automobile, two brake benches in the pair of front brake benches are arranged at intervals from left to right The two brake plates in the pair of rear brake plates are arranged at intervals from left to right. The base body can be a metal structure or a concrete structure. A force sensor 13 arranged horizontally is arranged between the base body and the corresponding braking platen. The force sensor is used to detect the braking force borne by the braking platen. A load cell 6 arranged vertically is arranged between the brake plates, and the load cell is used to detect the axle load borne by the corresponding brake plate.
 An example of a verification method for a flat brake test platform Figure 1~3 Shown: the method includes the following steps, the first step is to place the rear outrigger of the verification device on the corresponding braking platform, and place the front outrigger of the verification device on the front side of the braking platform; the second Step, the car runs from back to front, a pair of front wheels of the car drive to the weighing verification plate of the verification device, the rear wheels of the car are no longer on the brake plate to be verified, the weight measured by the standard weighing verification sensor The value is compared with the weight value measured by the load cell of the flat-plate brake inspection platform to verify the load cell. By moving the car back and forth on the weighing verification board, multiple sets of verification data are obtained.
 The verification device includes a weighing verification part for verifying the load cell 6 and a force sensor verification part for verifying the force sensor 13 . The weighing verification part includes two weighing verification boards 3 arranged at intervals from left to right when in use. The weighing verification board is a bar-shaped structure whose length extends along the front and rear directions. The front end of the verification board is provided with a front outrigger 4, and the rear end of the weighing verification board is provided with a rear outrigger 9 for supporting and cooperating with the corresponding braking platen. The rear outrigger includes the rear outrigger body and the The standard weighing verification sensor 8 on the leg body, the standard weighing verification sensor is vertically arranged, the rear outrigger body 7 is a vertically arranged strut in this embodiment, and the standard weighing verification sensor 8 is arranged on the rear outrigger body bottom of. The weighing verification plate 3 has an upper plate surface extending along the front-rear direction for the wheels of the corresponding automobile to move and walk in the front-rear direction. A ramp 10 is arranged at the rear end of the weighing verification board, and the lowest position of the bottom of the ramp 10 is higher than the lowest position of the rear legs.
 When verifying the load cells corresponding to the two brake plates at the front, place the front legs of the verification device on the base 5 on the front side of the corresponding brake plates, and place the rear legs of the verification device on the corresponding On the brake plate of the vehicle, the verification personnel can drive the car so that the front wheels of the car travel from back to front through the ramp to the upper surface of the weighing verification board. The setting of the ramp can reduce the weight of the weighing verification board of the car Impact, protect the standard weighing verification sensor and avoid the lifting and displacement of the weighing verification board, and the lowest position of the bottom of the ramp is higher than the lowest position of the rear outrigger, so the current wheel travels to the upper surface of the weighing verification board Finally, the ramp will not affect the normal verification process. The verification process is completed by comparing the measured value of the standard weighing verification sensor with the measured value of the weighing sensor of the brake inspection platform. When multiple sets of verification data are required, you can pass The car moves back and forth to achieve this. In the present invention, there is no need to use the gantry and the hydraulic cylinder to provide the test pressure, but to provide the test pressure through the very convenient way of the car, so that the structure of the test device itself is very simple and easy to carry.
 The force sensor verification part includes a substrate fixing seat 14 fixed on the upper end of the base body 5 and a platform fixing seat 18 fixed on the upper end of the corresponding braking platen 11 during use. The opposite sides of the substrate fixing seat 14 and the platform fixing seat 18 are Slopes 16 whose spacing gradually increases from top to bottom. In this embodiment, when in use, the base body fixing seat is fixed on the base body by bolts, and the platen fixing seat is fixed on the braking platen by bolts. Both the base body fixing seat and the platen fixing seat are of cover structure. A verification hydraulic cylinder 15 is installed on the top, and the piston rod of the verification hydraulic cylinder is connected with the platen fixing seat through a force transmission structure. A standard force sensor 20 is arranged in series on the rod 19, and the standard force sensor is arranged horizontally.
 When verifying the force sensor, fix the base body fixing seat on the base body, fix the platen fixing seat on the corresponding brake platen, apply pulling or pushing force through the hydraulic cylinder, and use the standard force sensor to control the brake inspection platform. Check the force sensor. Compared with the prior art, the inspection panel is directly removed, and a standard force sensor is installed, and then verified by the vehicle's force sensor, the verification method is much simpler.
 In other embodiments of the present invention: the verification device in the present invention may not include a force sensor verification part; the weighing verification board may also have only one piece, and the weighing verification board spans a pair of braking platens along the left and right directions. The bottom of the weighing verification board is provided with two rear outriggers, and the two rear outriggers correspond to the left and right braking platens respectively; the ramp can also be omitted.
