Technical Field

[0001] The present invention relates to the technical field of road construction, and in particular to road surface detection equipment and a construction method thereof for highway engineering. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbeds, pavements, bridges, culverts, tunnels, drainage systems, safety and protection facilities, greenery, and traffic monitoring facilities, as well as buildings, workshops, and other service facilities used for construction, maintenance, and monitoring.

[0003] During highway construction, multiple road surface inspections are required. Thickness testing is one of these inspection processes. Most road pavement thickness measurement equipment only has sampling capabilities, requiring subsequent centralized measurement. This prevents integrated sampling and measurement, hindering work efficiency. Summary of the Invention

[0007] a hanger, positionally adjustable and mounted on the movable base, the hanger having a first end and a second end opposite to each other;

[0008] a drilling machine, mounted liftably on the first end of the hanger;

[0009] The cam is secured to the bottom of the drilling rod and is adapted to engage the drill bit and engage with the guide wheel so that the drill bit can be engaged with the guide wheel and the guide wheel can be engaged with the drill bit.

[0010] Furthermore, the probe rod is provided with scale lines, and the scale lines are arranged along the vertical direction.

[0011] Furthermore, the movable base is provided with a first slide groove, and the hanger includes:

Screws are rotatably installed on the two ear plates, and the screws are arranged in the same direction as the first slide groove. The column is provided with a threaded hole, and the screw is screwed into the threaded hole of the column.

[0016] Furthermore, the movable base is equipped with a motor for driving the screw.

[0017] Furthermore, the drilling machine is mounted on the supporting plate in a liftable manner via an electric hydraulic push rod.

[0018] Furthermore, second sliding grooves are formed on opposite sides of the two support rods, and the second sliding grooves are arranged in the vertical direction. The two ends of the support beam are respectively slid into the second sliding grooves of the two support rods, and the support rods are equipped with driving parts for pushing the support beam.

[0019] Furthermore, a block for abutting against the upper portion of the movable base is formed on the exterior of the positioning sleeve.

[0020] Furthermore, the locking mechanism includes:

[0021] The cylinder is fixed on the outside of the positioning sleeve;

[0028] Adjusting the position of the hanger so that the probe rod of the detection device is aligned with the vertical through hole;

[0029] Lowering the support beam of the detection device so that the probe rod passes through the vertical through-hole and extends into the detection hole, and the movable base is supported on the positioning sleeve;

After the road surface detection equipment for highway engineering of the present invention is moved into place, the road surface is first sampled by drilling holes, and then the road surface thickness is measured by drilling holes, thereby avoiding step-by-step measurement and improving the efficiency of road surface thickness measurement.

[0041] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Reference Figures 1 to 5 As shown, the present invention provides a road surface detection device for highway engineering, including: a mobile base 1, a hanger 2, a drilling machine 3, and a depth measuring device 4.

[0044] The movable base is rectangular. A plurality of rollers are mounted on the bottom of the movable base. The plurality of rollers are spaced apart along the circumference of the movable base. In some embodiments, the rollers are equipped with brakes to lock the rollers.

[0045] The movable base 1 is provided with a vertical through hole 10. The vertical through hole is arranged in the middle of the movable base.

[0046] The hanger 2 is adjustably mounted on the movable base 1. The hanger 2 has a first end and a second end opposite to each other.

[0047] The drilling machine 3 is mounted on the first end of the hanger 2 in a liftable manner.

[0048] The depth sounding device 4 includes a support beam 41 , a probe rod 42 and a positioning sleeve 43 .

[0049] Specifically, a support beam 41 is movably mounted on the second end of the hanger 2. A borehole rod 42 is vertically mounted on the support beam 41. A positioning sleeve 43 is movably mounted on the exterior of the borehole rod 42. The positioning sleeve 43 has a through-hole. A driven wheel 44 is rotatably mounted within the through-hole. One side of the driven wheel 44 extends into the positioning sleeve 43 and presses against the borehole rod 42. The positioning sleeve 43 is equipped with a locking mechanism 45 for locking the driven wheel 44.

[0050] After drilling machine 3 cores the surface to be tested to form a probe hole, the position of hanger 2 on mobile base 1 is adjusted so that the probe rod 42 is aligned with the vertical through-hole 10. Support beam 41 is lowered to allow the probe rod 42 to pass through the vertical through-hole and into the probe hole, with mobile base 1 supported by positioning sleeve 43. After the probe rod 42 reaches the bottom of the probe hole, locking mechanism 45 locks driven wheel 44, locking positioning sleeve 43 to the probe rod 42.

[0051] The road surface detection equipment for highway engineering of the present invention adjusts the position of a hanger on a mobile base and then uses a drilling machine to drill a vertical hole in the ground to form a detection hole. Then, by adjusting the position of the hanger on the mobile base, a probe rod of a depth measuring device is passed through the vertical hole to detect the detection hole. Finally, the distance between the bottom end of the probe rod and the positioning sleeve is calculated and the distance between the positioning sleeve and the ground is subtracted to obtain the depth of the detection hole as the thickness value of the road surface to be measured. After the road surface detection equipment of the present invention is moved into position, the road surface is first sampled by drilling a hole, and then the road surface thickness is measured by drilling a hole, thereby avoiding step-by-step measurement and improving the efficiency of road surface thickness measurement.

[0052] As a preferred embodiment, see Figure 2As shown, the mobile base 1 is provided with a first chute. In this embodiment, the first chute is provided on two opposite sides of the mobile base. The hanger 2 includes a load-bearing plate 21, a column 22 and two support rods 23.

[0053] A support plate 21 is positioned above one end of the base 1. A column 22 is connected to the support plate 21. The lower end of the column 22 slides into a first chute. Two support rods 23 are positioned opposite each other. The support rods 23 are connected to one end of the support plate 21. The ends of the support beam 41 are mounted on the two support rods 23 in a manner that allows them to be raised and lowered.

[0054] Continue reading Figure 2 As shown, the movable base 1 is formed with two lugs 11. The lugs 11 are disposed at opposite ends of the first chute. Screws 12 are rotatably mounted on the lugs 11. The screws 12 are disposed in the same direction as the first chute. A threaded hole is formed in the column 22. The screws 12 are screwed into the threaded holes in the column 22.

[0055] In this embodiment, the mobile base 1 is equipped with a motor 13 for driving a screw 12. Specifically, the motor's output shaft is coaxially connected to the screw. The forward and reverse rotation of the motor drives the screw, which in turn moves the column along the length of the first chute to adjust the position of the hanger on the mobile base.

[0056] See Figure 3 In this embodiment, the drilling machine 3 is mounted on the supporting plate 21 in a liftable manner via an electric hydraulic push rod 31. Specifically, two electric hydraulic push rods are mounted on the bottom of the supporting plate. The electric hydraulic push rods are arranged vertically. The fixed ends of the electric hydraulic push rods are connected to the supporting plate, and a connecting rod is connected between the telescopic ends of the two electric hydraulic push rods. The drilling machine is mounted on the connecting rod. The drilling machine is positioned downward and is located in the middle of the connecting rod.

[0057] Recombination Figure 2 As shown, the support rod and the column are respectively arranged at both ends of the bearing plate. After the exploration rod is aligned with the vertical through hole, the bottom end of the support rod is placed on the upper part of the mobile base.

[0058] Second chutes are formed on opposite sides of the two support rods 23. The second chutes are arranged in a vertical direction. The two ends of the support beam 41 are slidably mounted in the second chutes of the two support rods 23. The support rods 23 are equipped with a drive member. The drive member is used to push the support beam 41.

[0059] In this embodiment, the outer diameter of the positioning sleeve is larger than the size of the vertical through hole. Preferably, a clamping block 431 is formed on the outside of the positioning sleeve 43. The clamping block 431 is used to abut against the upper part of the mobile base 1.

[0060] Specifically, clamping blocks are formed at opposite ends of the positioning sleeve.

[0061] See Figures 4 to 6 The locking mechanism 45 includes: a cylinder 451 and a pressure plate 452.

[0062] The air cylinder 451 is fixedly mounted on the outside of the positioning sleeve 43. The pressing plate 452 is connected to the piston rod of the air cylinder 451. After the piston rod is extended, the pressing plate 452 presses against the roller to lock the driven wheel 44.

[0063] In this embodiment, the driven wheel is a gear. A rack is formed on the side wall of the probe rod. The rack is arranged along the axial direction of the probe rod. The driven wheel meshes with the rack of the probe rod.

[0064] The side of the pressing plate away from the cylinder is formed with an anti-skid tooth pattern. After the piston rod of the cylinder is extended, the anti-skid tooth pattern of the pressing plate engages with the side of the driven wheel away from the rack to lock the driven wheel.

[0065] In this embodiment, the probe rod 42 is provided with scale lines, and the scale lines are arranged along the vertical direction.

[0066] The present invention provides a construction method of a road surface detection device for a highway project, comprising the following steps:

[0067] S1: Move the mobile base 1 to the road surface to be tested, so that the vertical through-hole 10 of the mobile base 1 is aligned with the detection point of the road surface to be tested;

[0068] S2: Adjust the position of the hanger 2 so that the drilling machine 3 is aligned with the vertical through-hole 10 .

[0069] S3: lowering the drilling machine 3 so as to allow the drilling machine 3 to pass through the vertical through-hole 10 and drill a core hole in the road surface at the detection point to form a detection hole.

[0070] S4: Lift the drilling machine 3 to move the drilling machine 3 back to above the vertical through-hole 10 .

[0071] S5: Adjust the position of the hanger 2 so that the probe rod 42 of the detection device is aligned with the vertical through hole 10.

[0072] S6: Lower the support beam 41 of the detection device so that the probe rod 42 passes through the vertical through hole and extends into the detection hole, and the movable base 1 is supported on the positioning sleeve 43.

[0073] S7 : After the probe rod 42 reaches the bottom of the detection hole, the locking mechanism 45 locks the driven wheel 44 of the detection device, so that the positioning sleeve 43 is locked to the probe rod 42 .

[0074] S8: Lift the support beam 41 so that the exploration rod 42 retreats to above the vertical through hole 10.

[0075] S9: Observe the distance from the bottom end of the probe rod 42 to the positioning sleeve 43 to calculate the thickness of the road surface to be measured.

[0076] In this embodiment, the distance h from the upper surface of the mobile base to the upper surface of the road surface to be measured is known. The distance H from the bottom end of the probe rod 42 to the positioning sleeve 43 can be directly read from the scale. Therefore, the depth of the probe hole H1 = Hh, and the depth of the probe hole is equal to the thickness of the road surface to be measured (theoretically, the drilling depth of the drilling machine is adapted to the thickness of the road surface to be measured).
