[0033] A road surface compression testing device includes a mobile frame 1 to move the entire device. A lifting assembly 2 is installed inside the mobile frame 1, and a coring assembly 3 is installed on the lifting assembly 2. The lifting assembly 2 is used to control the lifting of the coring assembly 3 to complete the coring operation.

[0034] The mobile frame 1 includes a frame body 11 and a universal wheel 12. The universal wheel 12 is installed on the bottom surface of the frame body 11.

The transmission box 21 is arranged on the top surface of the mobile frame 1, and the outer wall of the transmission box 21 passes through the rotationally connected handwheel shaft 22, the handwheel 23 is arranged on the outer side of the handwheel shaft 22, the inner side of the transmission box 21 is rotationally connected to the positioning shaft 24, the positioning shaft 24 and the handwheel shaft 22 are both mounted with the bevel gear 25, and the two bevel gears 25 are meshed for transmission, the support plates 26 are respectively arranged on the upper and lower sides of the mobile frame 1, the lifting shaft 27 is rotationally connected between the support plates 26, the top of the lifting shaft 27 passes through the support plate 26 and extends to the inside of the transmission box 21, the transmission wheels 28 are both mounted on the lifting shaft 27 and the positioning shaft 24, and the belts 29 are covered on the outer sides of the two transmission wheels 28. The worker shakes the hand wheel 23 to drive the positioning shaft 24 to rotate through the meshing transmission of the bevel gear 25, and then drives the lifting shaft 27 to rotate through the belt 29 of the transmission wheel 28, thereby realizing the up and down movement of the coring assembly 3 installed on the lifting shaft 27.

[0036] The coring assembly 3 includes a moving plate 31, a sliding plate 32, a motor box 33, a motor 34, a transmission shaft 35, and a coring drill bit 36. The moving plate 31 is arranged on one side of the motor box 33, and the moving plate 31 is installed at the output end of the lifting assembly 2, that is, it is rotatably connected with the lifting shaft 27. The sliding plates 32 are arranged on both sides of the motor box 33, and the other end of the sliding plate 32 is slidably connected with the moving frame 1. The motor 34 is installed on the top surface of the inner cavity of the motor box 33, and the output shaft of the motor 34 is connected to the transmission shaft 35. The transmission shaft 35 extends to the outside of the motor box 33 and is provided with the coring drill bit 36. The worker shakes the hand wheel 23, thereby rotating the lifting shaft 27. Under the limit of the sliding plate 32, the coring drill bit 36 ​​can only move up and down, thereby completing the coring operation. When coring, the motor 34 is started to drive the coring drill bit 36 ​​to rotate. At the same time, the worker shakes the hand wheel 23 to lower the coring drill bit 36 ​​to perform coring.

[0037] It also includes a water spray assembly 4, which is installed around the coring assembly 3 to reduce dust during the coring process and cool the coring drill bit 36.

[0038] The water spray assembly 4 includes a water tank 41, a water pump 42, a water spray ring 43, and a connecting rod 44. The water tank 41 is arranged inside the mobile frame 1, the water pump 42 is installed on one side of the water tank 41, the connecting rod 44 is arranged on one side of the support plate 26, and the water spray ring 43 is arranged on the other end of the connecting rod 44. The inner diameter of the water spray ring 43 is adapted to the core drill bit 36. The water spray ring 43 is a hollow structure, and a plurality of nozzles are arranged on the inner side wall and the bottom surface of the water spray ring 43. The input end of the water pump 42 and the water tank, and the output end of the water pump 42 and the water spray pipe are connected through pipes. The water pump 42 pumps the water in the water tank 41 to the water spray ring 43 for spraying. The core drill bit 36 ​​passes through the water spray ring 43, and the nozzle inside the water spray ring 43 directly sprays water on the surface of the core drill bit 36 ​​to cool it down. The nozzle on the bottom of the water spray ring 43 sprays water near the drill hole to cool the core drill bit 36 ​​in this area.

[0039] A lifting push rod is installed between the connecting rod 44 and the water spray ring 43. Driven by the lifting push rod, the position of the water spray ring 43 can be adjusted up and down, so that the water sprayed by the water spray ring 43 can be sprayed more onto the surface of the coring drill bit 36.

[0040] It also includes a dust suction component 5, which is installed around the core removal component 3 to reduce dust.

[0041] The dust suction assembly 5 includes a negative pressure fan 51 and a back-suction ring 52. The back-suction ring 52 is installed on the bottom surface of the motor box 33. The back-suction ring 52 is a hollow structure. The bottom surface of the back-suction ring 52 is provided with a plurality of back-suction holes. The negative pressure fan 51 is installed on the top surface of the motor box 33. The negative pressure fan 51 and the back-suction ring 52 are connected through a pipeline. The shape of the back-suction ring 52 is adapted to the bottom surface of the motor box 33. A window is provided on the top surface of the core drill bit 36, which is convenient for sucking the dust inside on the one hand and for taking out the drilled road surface on the other hand.

[0042] It also includes a braking support assembly 6, which is installed at the lower part of the mobile frame 1 to fix the entire equipment during the coring process.

[0043] The brake support assembly 6 includes a foot ring 61, a sliding shaft 62, a brake plate 63, a stopper 64, a brake plug 65, and a connecting plug 66. A brake groove is provided through the lower part of the mobile frame 1, and a pair of sliding shafts 62 are slidably connected in the brake groove. The foot ring 61 is provided on the top of the sliding shaft 62, and the brake plate 63 is provided on the bottom of the sliding shaft 62. The stopper 64 is provided in the middle of the brake groove, and the connecting plug 66 is provided on both sides of the stopper 64. The other end of the connecting plug 66 is fixedly connected to the inner side of the brake plug 65. The brake plug 65 is in a herringbone shape, and the two ends of the brake plug 65 point to the sliding shaft 62. There are 4 brake support assemblies 6 in total, which are respectively located at the four corners of the mobile frame 1. The bottom surface of the brake plate 63 is provided with a friction pad. When coring, the worker directly steps on the foot ring 61 until the brake plate 63 on the bottom surface contacts the ground and the friction pad is squeezed. When the equipment is moved, the friction pad and the bottom surface generate friction to limit movement. At this time, the foot ring 61 squeezes the brake plug 65, so that the brake plug 65 presses against the sliding shaft 62 to fix the sliding shaft 62 and prevent it from moving upward, resulting in brake failure.

[0044] When the present invention is used:

[0045] Push the device to the position to be coring, then step on the foot ring until the brake plate contacts the ground, and the preparation work is now complete.

[0046] Then the motor, the fan and the water pump are started, and the worker shakes the hand wheel to drive the coring drill bit to move downward to perform the coring operation; the fan drives the suction ring to absorb dust during the coring process; the water pump draws water from the water tank into the water spray ring and sprays it out to cool the coring drill bit.

[0047] When coring is completed, the worker shakes the hand wheel to disengage the coring drill bit from the road surface, and then removes the coring drill bit from the road surface.
