DETAILED DESCRIPTION

[0027] Example 1

[0028] The specific embodiment is a damping type seesaw device with embedded pre-embedded for vehicle testing, the structural schematic diagram is shown in Figures 1-6 The concrete ramp 1 is provided with two concrete ramps 1, and the seesaw tool 2 is located between the two concrete ramps 1. The seesaw tool 2 includes a base 201, a bearing seat 202, a seesaw frame 203, and a seesaw 204. The two ends of the middle part of the seesaw frame 203 are rotatably installed on the base 201 through the bearing seat 202. An installation groove for installing the seesaw 204 is formed in the seesaw frame 203. The seesaw 204 is fixedly installed in the inside of the installation groove, and the surface of the seesaw 204 is flush with the surface of the seesaw frame 203. The base 201 is hingedly connected with the seesaw frame 203 through the damper 205 on both sides.

[0029] Before the automobile test, one end of the seesaw frame 203 is overlapped in the notch of one of the concrete ramps 1, so that the seesaw frame 203 and the concrete ramp 1 form an integral uphill ramp;

[0030] During the automobile test, the automobile first drives on one of the concrete ramps 1, and then drives on the seesaw frame 203. The wheels on both sides of the automobile drive on the two seesaws 204, respectively. When the automobile drives to the other side of the seesaw bearing seat 202, the weight of the automobile will exert a force to make the seesaw frame 203 rotate through the bearing seat 202, until the other end of the seesaw frame 203 is overlapped in the notch of the other concrete ramp 1. At this time, the seesaw frame 203 and the other concrete ramp 1 form a downhill ramp. Since the damper 205 is hingedly connected between the base 201 and the seesaw frame 203 on both sides, the dampers 205 on both sides of the base 201 are stretched and compressed when the seesaw frame 203 rotates around the bearing seat 202. When the dampers 205 are stretched and compressed, they play a buffering role for the seesaw frame 203, so that the rotation speed of the seesaw frame 203 is slowed down, preventing the seesaw frame 203 from rotating too fast, which causes the automobile to receive a large jolt in an instant when the seesaw frame 203 is overlapped in the notch of the concrete ramp 1, resulting in a large shaking of the vehicle body and a large impact on the driver.

[0031] In some embodiments, each bearing seat 202 includes two lower bearing seats 2021 fixedly connected to the top of the base 201, a rotating shaft 2022 rotatably mounted on the two lower bearing seats 2021, and an upper bearing seat 2023 fixedly connected to the bottom of the seesaw frame 203, and the upper bearing seat 2023 is fixedly mounted on the middle part of the rotating shaft 2022, and the rotating shaft 2022 can adopt a damping rotating shaft;

[0032] When the seesaw frame 203 rotates through the bearing seat 202: the seesaw frame 203 first drives the upper bearing seat 2023 to rotate, and the upper bearing seat 2023 drives the rotating shaft 2022 to rotate, thereby realizing the relative rotation between the seesaw frame 203 and the base 201.

[0033] In some embodiments, the lower surface of one end of the seesaw frame 203 is fixedly connected with a counterweight 2031 on both sides, and the mass of each counterweight 2031 is 100 kg. Through the arrangement of the counterweight 2031, the seesaw frame 203 can be automatically reset.

[0034] In some embodiments, the bottom of both ends of the seesaw 204 is fixedly connected with a buffer block, and the material of the buffer block includes but is not limited to rubber. Through the arrangement of the buffer block, the seesaw frame 203 has a buffering protection effect when the seesaw frame 203 is lapped on the gap of the concrete ramp 1.

[0035] In some embodiments, the upper surface of the seesaw frame 203 is fixedly connected with a support 2032 on both sides in the middle, and the two sides of the support 2032 are fixedly installed with a cable-stayed cable 2033, and the end of the cable-stayed cable 2033 away from the support 2032 is fixedly installed on the seesaw frame 203.

[0036] In some embodiments, the concrete ramp 1 is provided with a gap near one end of the seesaw frame 203, and a pre-embedded plate 101 is pre-embedded in the gap. The pre-embedded plate 101 includes a steel plate located in the gap and a pre-embedded rod poured in the concrete ramp 1, and the steel plate is fixedly connected with the pre-embedded rod, for example, by welding. The pre-embedded rod can be a round steel bar or a threaded steel bar.

[0037] The pre-embedded plate 101 is fixedly installed with a polyurethane strip 102. Threaded holes are formed in the surface of the pre-embedded plate 101, and counterbores are formed in the polyurethane strip 102. The polyurethane strip 102 is fixedly installed on the pre-embedded plate 101 by bolts.

[0038] When the seesaw frame 203 is lapped on the gap of the concrete ramp 1, the seesaw frame 203 is in contact with the polyurethane strip 102, which has a protective effect on the seesaw frame 203 and the concrete ramp 1.

[0039] In some embodiments, the top of the concrete ramp 1 is fixedly installed with anti-collision fences 103 on both sides, and the anti-collision fences 103 include but are not limited to corrugated protective highway anti-collision fences.

[0040] Embodiment 2

[0041] The difference from Embodiment 1 is that two pulley sets 104 are fixedly installed on the concrete ramp 1, and the two pulley sets 104 are diagonally staggered left and right, the central distance between the two pulley sets 104 is 2.4 meters, each pulley set 104 includes a plurality of rollers, and the two ends of the roller are fixedly installed in the inner ring of the bearing, and the bearing is fixedly installed in the interior of the concrete ramp 1.

[0042] When the car drives uphill on one of the concrete ramps 1, the wheels on both sides of the car drive on the two pulley sets 104 respectively, which can test the driving ability of the wheels when the car climbs the slope and the wheels slip. When the car drives uphill on the other concrete ramp 1, the wheels on both sides of the car drive on the two pulley sets 104 respectively, which can test the braking ability of the wheels when the car descends the slope and the wheels slip.

[0043] All the technical features in the embodiment can be freely combined according to actual needs.

[0044] The above embodiments are the preferred implementation scheme of the present application, in addition to this, the present application can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
