DETAILED DESCRIPTION

[0028] The utility model will be further explained in detail below in combination with the drawings.

[0029] As shown in Figure 1 , Figure 2 , an asphalt pavement coring device comprises a support frame 1, a speed reducer 2, a driving mechanism 3, a coring barrel 4, a mounting plate 5, a protective cover 6 and a counterweight ring 7.

[0030] As shown in Figure 2 , Figure 3 , the support frame 1 is provided with universal wheels 11 at the bottom, and a handrail 12 is arranged at the upper end to facilitate the control of the support frame 1 to walk on the ground.

[0031] As shown in Figure 2 , Figure 3 , the speed reducer 2 is vertically slidably connected to the support frame 1, and the upper end of the speed reducer 2 is provided with an end seat 21, and a guide rod 22 is vertically arranged on the end seat 21 and penetrates the upper end of the support frame 1, and a spring 23 is arranged on the outer wall of the guide rod 22 between the end seat 21 and the support frame 1.

[0032] As shown in Figure 2 , Figure 3 , the driving mechanism 3 is used for controlling the vertical sliding of the speed reducer 2, and the driving mechanism 3 comprises a driving seat 31 and a roller 32, the driving seat 31 is arranged on the handrail 12, the handrail 12 is rotatably connected to the support frame 1, and the roller 32 is arranged on the driving seat 31 and used for abutting against the upper end face of the end seat 21 after the handrail 12 is turned over.

[0033] As shown in Figure 2 , Figure 3 , the support frame 1 is provided with a locking rod 13 for inserting the handrail 12 to fix the handrail 12 when the handrail 12 is pushed to drive the whole coring device to walk, thereby increasing the stability and convenience of the coring device when moving. At the same time, the handrail 12 is arranged in a turnover mode, which can conveniently walk on the ground through the support frame 1, and can also slide the speed reducer 2 by turning over, thereby realizing the dual-purpose of the handrail 12 and improving the practicability of the coring device.

[0034] As shown in Figure 2 , Figure 3As shown, the coring barrel 4 is arranged on the shaft of the speed reducer 2, and the lower end is open, and the mounting plate 5 is arranged on the lower end side wall of the speed reducer 2. The protective cover 6 is arranged on the mounting plate 5 in a flexible manner, and surrounds the coring barrel 4, and the counterweight ring 7 is arranged at the lower end of the protective cover 6 and is used to abut against the ground.

[0035] As shown in the drawings, Figure 2 , Figure 3 The protective cover 6 is embedded with a spiral elastic member 61, and the elastic member 61 is fixed to the mounting plate 5 and the counterweight ring 7. A pair of pull rods 71 are vertically arranged on the counterweight ring 7, and a pull ring 72 surrounding the speed reducer 2 is arranged between the upper ends of the pair of pull rods 71.

[0036] When core sampling is needed, the control handle 12 drives the support frame 1 to move on the ground, and when it moves to the vicinity of the position where core sampling is needed, the pull ring 72 is pulled to drive the pull rod 71 to move upward, at which time the pull rod 71 drives the counterweight ring 7 to move upward synchronously, so that the coring barrel 4 is exposed, then the position of the support frame 1 is adjusted to align the coring barrel 4 with the position where sampling is needed, and the pull ring 72 is released, so that the counterweight ring 7 slides downward and abuts against the ground.

[0037] Then the locking rod 13 is pulled to disengage from the handle 12, then the handle 12 is controlled to rotate, so that the rollers 32 on the handle 12 abut against the end seat 21 on the speed reducer 2, then the handle 12 is pressed to move downward, so that the handle 12 drives the end seat 21 and the speed reducer 2 to move downward, so that the coring barrel 4 gradually moves downward.

[0038] And when the coring barrel 4 moves downward, the protective cover always surrounds the coring barrel 4, so that the coring barrel 4 works in a closed environment, and as the coring barrel 4 descends, the protective cover can automatically deform to ensure that the coring barrel 4 smoothly samples.

[0039] Finally, the handle 12 is controlled to move upward, and under the action of the spring 23, the control end seat 21 and the speed reducer 2 move upward, so that the coring barrel 4 slides upward, and finally the core sample taken out is taken out in the coring barrel 4, that is, the coring operation of the asphalt pavement is completed.

[0040] By arranging the telescopic deformation type protective cover 6, the surrounding of the coring barrel 4 is protected during the coring process of the coring barrel 4, so as to prevent the slurry from splashing and polluting the ground, and also to avoid the slurry from polluting the clothes of the construction personnel, so as to achieve the effect of reducing the pollution to the surrounding environment.

[0041] As shown in the drawings, Figure 2 , Figure 3As shown, the support frame 1 has vertically sliding feet 14 on both sides for contacting the ground, and a screw 15 is vertically threaded onto the side wall of the support frame 1. The lower end of the screw 15 is rotatably connected to the upper end of the foot 14. Therefore, when drilling, the screw 15 is rotated to make the foot 14 contact the ground, thus supporting the support frame 1, increasing the stability of the support frame 1, and achieving accurate and stable core sampling.

[0042] like Figure 1 As shown, the side wall of the support frame 1 is provided with multiple sampling tubes 8 with open tops. The side wall of the sampling tube 8 is provided with a label 81, and the top end is provided with a hook 82 for engaging the support frame 1. Therefore, by setting multiple independent sampling tubes 8 and marking the core sample inside the sampling tube 8 with the label 81, stable and independent storage of the core sample can be achieved, which is convenient for later testing.
