Description

Technical Field

[0001] The utility model relates to the technical field of roadbed deflection detection, in particular to a highway roadbed deflection detection vehicle. Background Art

[0002] Pavement deflection generally refers to the total vertical deformation value (total deflection) or vertical rebound deformation value (rebound deflection) of the roadbed or road surface at the wheel gap position under the load of a specified standard vehicle. Pavement deflection not only reflects the overall strength and stiffness of the road structure layer and soil layer, but also has a certain internal connection with the use status of the road surface. As an important testing indicator after the completion of the project, it reflects the overall strength quality of the road surface. The greater the deflection, the easier it is for the road surface to be damaged. If the deflection is greater than the designed deflection, the road surface is unqualified. Therefore, it is necessary to test the deflection of the roadbed after the construction of the roadbed is completed. The traditional deflection test is mainly carried out by the Beckmann beam method. This method requires workers to carry two 3-6 meter long Beckmann beams and move them behind a ten-ton test vehicle for section-by-section testing. This is not only inefficient, but also requires multiple workers to carry the Beckmann beams, which takes up a lot of labor.

[0003] In order to save labor, some auxiliary detection devices are also used, but these devices still need multiple workers to carry them when in use, which occupies more workers' labor and has low detection efficiency. For this reason, a highway subgrade deflection detection vehicle is proposed. Utility Model Content

In this way, there is no need to install an electric roller under the main machine, saving motor costs.

[0016] 3. A highway subgrade deflection detection vehicle can guide the adsorption boss to correctly align with the lower part of the electromagnet through a guide platform to prevent deflection and cause workers to spend extra time to place it.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Embodiment 1:

[0030] like Figure 1-6As shown, a highway subgrade deflection detection vehicle comprises a main machine 1 and a Beckman beam 3. An electrically driven roller capable of actively moving is provided below the main machine 1. A slot is provided above the main machine 1. An extension rod 5 is slidably connected to the main machine 1. The extension rod 5 can slide in the slot. A lifting push rod 15 is fixedly connected to one end of the extension rod 5. An electromagnet 16 and a clamping assembly are fixedly connected to the movable end of the lifting push rod 15. An adsorption boss 14 is fixedly connected to the top of the Beckman beam 3. A clamping slot 13 is provided on the other side of the Beckman beam 3.

[0031] The clamping assembly includes a clamping motor 17, a clamping claw 18, a rotating rod 19 and a connecting rod 20. The rotating rod 19 is fixedly connected to the power output end of the clamping motor 17, one end of the connecting rod 20 is rotatably connected to the rotating rod 19, and the other end of the connecting rod 20 is rotatably connected to the clamping claw 18.

[0032] When testing, the extension rod 5 can align the distance between the two Beckmann beams 3 with the distance between the rear wheels of the truck, and place one end of the Beckmann beam 3 on the rear wheel side of the front truck. After one test is completed, after the truck moves forward, one end of the lifting push rod 15 moves downward and then starts the electromagnet 16. At this time, the electromagnet 16 adsorbs the adsorption boss 14 for alignment, and then the clamping motor 17 works to translate the clamping claw 18 inward and clamp it in the clamping groove 13 on one side of the Beckmann beam 3;

[0033] Then the lifting push rod 15 contracts, lifts the Beckman beam 3, and drives the Beckman beam 3 forward through the electric drive roller under the main machine 1. There is no need for multiple workers to carry the six-meter-long Beckman beam 3. During work, only one staff member is needed to remotely control and record experimental data at the rear side of the device, which saves manpower and improves work efficiency.

[0034] In this embodiment, the clamping assembly further includes a limiting groove 21 and a limiting rod 22. One side of the limiting groove 21 is opened below the clamping motor 17. One end of the limiting rod 22 is slidably connected to the limiting groove 21, and the other end of the limiting rod 22 is fixedly connected to the top of the clamping claw 18.

[0035] The limiting rod 22 can slide linearly in the limiting groove 21 to ensure that the direction of the clamping jaw 18 will not deflect.

[0036] In this embodiment, a test rod 10 is fixedly connected to one end of the Beckman beam 3, and a support column 4 is fixedly connected to the middle of the Beckman beam 3. The support column 4 allows the Beckman beam 3 to be stably tested on the ground;

[0038] The meter frame 11 can be lifted together when the Beckman beam 3 is lifted. When the Beckman beam 3 is placed on the ground, the support plate 12 at the bottom of the meter frame 11 will also fall to the ground. Then the staff will check whether the dial indicator 24 is reset. After the load truck leaves, the test rod 10 will squeeze the pointer of the dial indicator 24 to display the settlement value.

[0039] In this embodiment, one end of the main machine 1 is rotatably connected to a double-headed screw 6, one side of the main machine 1 is fixedly connected to a drive motor 7, the power output end of the drive motor 7 is transmission-connected to the double-headed screw 6, one end of the double-headed screw 6 is threadedly connected to a transverse slider 8, and one end of the transverse slider 8 is rotatably connected to the extension rod 5;

[0040] The driving motor 7 can drive the double-headed screw rod 6 to rotate through the gear in the middle of the double-headed screw rod 6, and adjust the positions of the lifting push rods 15 on both sides to align with the trucks with different vehicle widths.

[0041] In this embodiment: when testing, the extension rod 5 can align the distance between the two Beckmann beams 3 with the distance between the rear wheels of the truck, and place one end of the Beckmann beam 3 on the side of the rear wheel of the front truck. After one test is completed, after the truck moves forward, one end of the lifting push rod 15 moves downward and then starts the electromagnet 16. At this time, the electromagnet 16 adsorbs the adsorption boss 14 for alignment, and then the clamping motor 17 works to translate the clamping claw 18 inward and clamp it in the clamping groove 13 on one side of the Beckmann beam 3;

[0042] Then the lifting push rod 15 is retracted, the Beckmann beam 3 is lifted and driven forward by the electric drive roller under the main machine 1, so that multiple workers are not needed to carry the six-meter-long Beckmann beam 3. During work, only one worker is needed to remotely control and record experimental data at the rear side of the device, which saves manpower and improves work efficiency;

[0043] The limit rod 22 can slide linearly in the limit groove 21 to ensure that the direction of the clamping claw 18 will not deflect. The meter frame 11 can be lifted together when the Beckman beam 3 is lifted. When the Beckman beam 3 is placed on the ground, the support plate 12 at the bottom of the meter frame 11 will also fall on the ground. Then the staff will check whether the dial indicator 24 is reset. After the load vehicle leaves, the test rod 10 will squeeze the pointer of the dial indicator 24 to display the settlement value.

[0044] The driving motor 7 can drive the double-headed screw rod 6 to rotate through the gear in the middle of the double-headed screw rod 6, and adjust the positions of the lifting push rods 15 on both sides to align with the trucks with different vehicle widths.
