A sliding hole 509 is opened on one side of the fixing block 505;

[0023] The pavement core drill has three rows of pulleys, and the three rows of pulleys just abut on the three ramps, which can assist the pavement core drill to get on and off the vehicle, reduce the labor intensity of personnel and the number of required personnel. The positions of the middle ramp 3 and the side ramp 4 can be fixed through the fixing component 5 to prevent them from shifting during the handling process and increase the reliability.

[0024] Please refer to Figures 1 to 3, at least one mounting hole 2 is provided on the upper surface of the mounting frame 1. The mounting frame 1 is fixedly installed with the middle inclined path 3 and the side inclined path 4 through the mounting holes 2. The rotating shaft 501 is fixedly connected to the outer side of the side inclined path 4. The gear ring 502 is rotatably connected to the surface of the rotating shaft 501. The connecting rod 503 is fixedly connected to the bottom of the gear ring 502. The positioning wheel 504 is fixedly connected to one end of the connecting rod 503. The fixing block 505 is fixedly connected to the outer side of the side inclined path 4. The top end of the first spring 506 is fixedly connected to the inner wall of the fixing block 505. The limiting block 507 is fixedly connected to the bottom end of the first spring 506. The convex block 508 is fixedly connected to one side of the limiting block 507. A rack that matches the tooth groove model of the gear ring 502 is provided at the bottom of the limiting block 507. The limiting block 507 is engaged with the gear ring 502 through the bottom rack. The top ends of the middle inclined path 3 and the side inclined path 4 are provided with a vehicle bottom plate 8. The positioning wheel 504 is in contact with the bottom of the vehicle bottom plate 8;

[0025] Lap the upper ends of the middle inclined path 3 and the side inclined path 4 on the vehicle bottom plate 8, and at the same time make the buffer plate 6 abut against the ground. Then, pull up the convex block 508 to drive the limiting block 507 to move upward, so that the distance between the limiting block 507 and the gear ring 502 increases, and the engagement relationship is disconnected. Then, the connecting rod 503 can be rotated to make one end of the positioning wheel 504 in contact with the bottom of the vehicle bottom plate 8. Then, release the convex block 508, and the positions of the middle inclined path 3 and the side inclined path 4 can be fixed to prevent them from shifting during the handling process.

[0026] Please refer to Figure 1 and Figure 4 , buffer plates 6 are fixedly connected to the bottom ends of the middle inclined path 3 and the side inclined path 4. A buffer assembly 7 is arranged inside the buffer plate 6. The buffer assembly 7 includes a groove 701, a second spring 702, a force-receiving block 703, a sliding groove 704, and a sliding block 705. A groove 701 is provided on the upper surface of the buffer plate 6. The inner bottom of the groove 701 is fixedly connected to the second spring 702. The top end of the second spring 702 is fixedly connected to the force-receiving block 703. Sliding grooves 704 are provided on both inner walls of the groove 701. Both ends of the bottom of the force-receiving block 703 are fixedly connected to the sliding blocks 705, and the sliding blocks 705 are located inside the sliding grooves 704. Both sides of the force-receiving block 703 are inclined surfaces;

[0027] When the pulley of the pavement core drill passes through the buffer plate 6, first, the pulley presses the force-receiving block 703, causing the force-receiving block 703 to move downward and compressing the second spring 702 to deform. The sliding of the sliding block 705 in the sliding groove 704 can achieve a damping effect. Combining with the compression deformation of the second spring 702 can absorb the impact force and achieve a buffer effect to further protect the pavement core drill.

[0028] In the present utility model, the working principle of the device is as follows:

[0029] During use, the pavement coring machine is placed on the vehicle floor 8. The upper ends of the middle ramp 3 and the side ramp 4 are lapped on the vehicle floor 8. At the same time, the buffer plate 6 is abutted against the ground. Then, the lug 508 is pulled upward, driving the limit block 507 to move upward, compressing the first spring 506, increasing the distance between the limit block 507 and the gear ring 502, and disconnecting the engagement relationship. Then, the connecting rod 503 can be rotated so that one end of the positioning wheel 504 fits against the bottom of the vehicle floor 8. Then, the lug 508 is released, and the first spring 506 is reset due to the action of force, causing the limit block 507 to move downward and engage with the gear ring 502, which can fix the positions of the middle ramp 3 and the side ramp 4 and prevent them from shifting during transportation. The pavement coring machine has three rows of pulleys, and the three rows of pulleys just abut against the three ramps, which can assist the pavement coring machine to get on and off the vehicle, reducing the labor intensity of personnel and the number of required personnel;

[0030] When the pavement coring machine moves from the ramp to the ground, when the pulley of the pavement coring machine passes through the buffer plate 6, first, the pulley squeezes the force-receiving block 703, causing the force-receiving block 703 to move downward and compressing the second spring 702 to deform. The sliding of the slider 705 in the chute 704 can achieve a damping effect, and the compression deformation of the second spring 702 can absorb the impact force, achieving a buffering effect and further protecting the pavement coring machine.
