[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] Combination Figures 1 to 5As shown, the vehicle carrying device for safety inspection of this embodiment includes a ramp device 10, which includes two ramps 1 that are arranged in sequence and separately along the length direction of the vehicle, and the two ramps 1 respectively include a ramp section 1a that gradually increases in height along the direction close to the junction of the two ramps 1 in the length direction, and the ramp 1 includes at least two assembly modules 11 that are arranged side by side and separately along the width direction perpendicular to the length direction of the vehicle.

[0037] The ramp device 10 of the vehicle carrying device includes two separately arranged ramps 1, each ramp 1 includes two assembly modules 11 arranged side by side along the width direction of the vehicle, and the entire ramp device 10 includes multiple separately arranged assembly modules 11, which solves the problem that the integral ramp device 10 of the prior art is difficult to move and arrange. The arrangement of the vehicle carrying device in this embodiment can be completed by a single person.

[0038] like Figure 1 As shown, the vehicle carrying device includes two ramp devices 10, which are arranged along the width direction of the vehicle to carry the wheels on the left and right sides of the vehicle respectively. The vehicle carrying device includes two ramp devices 10, each of which includes a plurality of assembly modules 11, which decomposes the vehicle carrying device into a plurality of light-weight components, which is convenient for moving and transporting the vehicle carrying device.

[0039] In some embodiments, two adjacent assembly modules 11 in the width direction are detachably connected. Connecting two assembly modules 1 together to form a whole is helpful to prevent the ramp device 10 from moving on the ground.

[0040] Furthermore, in order to prevent the ramp device 10 from moving relative to the ground, the ramp device 10 also includes an anti-skid portion 4 provided at the bottom of the ramp 1 to prevent the ramp 1 from moving on the ground, so the ramp device 10 of this embodiment does not need to be anchored on the ground. The anti-skid portion 4 includes a plurality of anti-skid protrusions to increase the friction between the anti-skid portion and the ground, thereby facilitating the prevention of the ramp device 10 from moving on the ground. The anti-skid protrusions extend along the width direction of the vehicle, and the plurality of anti-skid protrusions are arranged along the length direction of the vehicle.

[0041] In some embodiments, the anti-skid portion 4 includes an anti-skid rubber pad. In other embodiments, the anti-skid portion 4 is an anti-skid structure formed on the bottom surface of the ramp 1, such as an anti-skid protrusion, an anti-skid pattern or an anti-skid spike.

[0042] In some embodiments, the angle between the upper surface of the ramp 1 or the ramp section 1a and the ground can be roughly determined based on the coefficient of kinetic friction when the vehicle moves on the upper surface.

[0043] Combination Figure 1 and 5As shown, the ramp 1 is provided with an anti-skid portion 4 at the lower part of one end close to the junction in the length direction of the vehicle; the ramp 1 is provided with an anti-skid portion 4 at the lower part of one end away from the junction in the length direction of the vehicle; and the ramp 1 is provided with an anti-skid portion 4 at the lower part of the middle part in the length direction of the vehicle. The multiple anti-skid portions 4 work together to prevent the ramp 1 from moving when a vehicle passes by.

[0044] When the vehicle passes over the ramp 1, the friction between the vehicle and the ramp 1 generates a large downward force at the end of the ramp 1 away from the junction. The anti-skid portion 4 at the lower part of the end of the ramp 1 away from the junction in the length direction of the vehicle can play a greater anti-skid role.

[0045] In some embodiments, the ramp 1 is provided with the above-mentioned anti-skid portion 4 at one end near the junction of the two ramps along the length direction of the vehicle. The anti-skid portion 4 extends on the bottom surface of the ramp 1 along the width direction of the vehicle.

[0046] Two ramps 1 of the ramp device 1 arranged in sequence along the length direction of the vehicle abut against each other. In other embodiments, the two ramps 1 are detachably connected.

[0047] In order to further prevent the ramp device from moving on the ground, the ramp device 10 also includes an anti-skid plate 5 provided at one end of the ramp 1 in the length direction of the vehicle away from the junction, and the anti-skid plate 5 abuts or is connected to the ramp 1. One end of the ramp 1 along the length direction of the vehicle abuts against another ramp 1, and the other end abuts against the anti-skid plate 5. The friction between the anti-skid plate 5 and the ground helps prevent the ramp 1 from moving along the ground.

[0048] Furthermore, since the anti-skid plate 5 is higher than the ground, when the vehicle passes through the vehicle carrying device, the wheels are located on the anti-skid plate 5, which is conducive to increasing the gap between the bottom of the frame and the highest point of the ramp 1, thereby preventing the vehicle from bottoming out.

[0049] See also Figure 5 Two adjacent assembly modules 11 of the ramp 1 are detachably connected via a pin 12 .

[0050] In some embodiments, in two adjacent assembly modules 11, the side of one assembly module 11 is provided with a lug 13 protruding toward the other assembly module 11, and the side of the other assembly module 11 is provided with a notch matching the lug 13 and a pin seat 14 provided below or above the notch, one of the lug 13 and the pin seat 14 is connected to the pin 12, and the other is provided with a pin hole matching the pin 12. In the process of assembling the assembly modules 11 into a ramp, it is only necessary to align the lug 13 of one assembly module 11 and insert it into the notch of the other assembly module 11, and the pin 12 can be inserted into the pin hole to achieve the connection between the two assembly modules 11. Figure 5As shown, the lower part of the pin seat 14 is provided with an anti-skid portion 4 to prevent the ramp 1 from moving when a vehicle passes by. The pin seat 14 is arranged in the middle of the ramp 1 in the length direction of the vehicle.

[0051] The lug 13 and the notch are matched in shape and size, and the lug 13 can prevent the two assembly modules 11 from moving along the length direction of the vehicle after being inserted into the notch.

[0052] In other embodiments, the lug 13 and the pin seat 14 are respectively provided with a first pin hole and a second pin hole matched with the pin 12, and the pin 12 is inserted into the first pin hole and the second pin hole.

[0053] In some embodiments, an installation cavity 2 for installing a detector for receiving detection radiation is provided between the two ramps 1, and a gap 3 is provided between the upper surfaces of the two ramps 1 and is connected to the installation cavity 2 to allow radiation to pass through.

[0054] In some embodiments, the ramp 11 further includes a horizontal section 1b located at the intersection of the ramp section 1a adjacent to the two ramps 1 , the mounting cavity 2 is located below the horizontal section 1b of the ramp 1 , and a gap 3 is formed between the horizontal sections 1b of the two ramps 1 .

[0057] In some embodiments, the vehicle supporting device further includes a second radiation detector installed between the two ramps 1 .

[0058] The vehicle carrying device is arranged in the detection channel between the radiation source and the first radiation detector. The ramp 1 is designed with a steel structure and is arranged in the detection channel of the safety detection system. An installation cavity 2 for the second radiation detector is left between the front and rear ramps 1. A gap 3 of a certain width required by the detector is left on the top of the ramp 1. A non-slip rubber pad is glued to the base at the bottom of the ramp 1 to increase friction with the ground.

[0059] See also Figure 1 and 2, two ramp devices 10 are arranged on the left and right sides of the detection channel, each ramp device 10 includes 4 ramp assembly modules 11, standing at the entrance of the detection system and looking towards the exit direction, there are defined entrance left ramp 1 (composed of assembly module No. 1 11 and assembly module No. 2 11), entrance right ramp 1 (composed of assembly module No. 1 11 and assembly module No. 2 11), exit left ramp (composed of assembly module No. 4 11 and assembly module No. 3 11) and exit right ramp (composed of assembly module No. 4 11 and assembly module No. 3 11).
