Description

Technical Field

[0001] The present invention relates to the technical field of highway engineering construction, and specifically provides a device for detecting the thickness of highway engineering construction. Background Technique

[0002] As the most fundamental and extensive transportation infrastructure, highways are the main support for connecting various other transportation modes and giving full play to the overall efficiency of the comprehensive transportation network, and play an irreplaceable role in the comprehensive transportation system. In highway pavement engineering, the thickness of each layer is closely related to the overall strength of the road. Only when the thickness is ensured can the strength of each layer and the whole of the road surface be guaranteed.

[0003] The existing methods for detecting the thickness of highway engineering construction mainly include ground-penetrating radar detection method and coring method. Among them, the coring method mainly drills holes in the road surface, takes samples, and then detects the thickness of the core samples. Some core samples also need to be moved to the laboratory for further detection. After the coring mechanism of the existing thickness detection device finishes drilling, either the core sample remains in the drill barrel and is not easy to take out, and it is necessary to knock on the outside of the drill barrel to make the core sample fall, or after the drill barrel leaves the hole, the worker still needs to manually clamp and take out the core sample and measure it with a steel ruler, and the operation is relatively cumbersome, the detection efficiency is relatively low, and the core samples are easy to be confused during storage; and the cooling water left during drilling enters the hole, affecting the subsequent filling of the hole.

[0033] In the following description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. The term "connection" only indicates the connection between devices and has no special meaning.

[0034] In addition, the technical fields and installation manners involved in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

A plurality of storage frames 443 are sequentially arranged on the storage component 4. A scale is arranged on the storage frame 443, and the plurality of storage frames 443 reciprocate by a lead screw nut structure;

[0036] The displacement distance of the two lifting parts 12 on the base 11 is the same as the distance between the clamping center of the clamping component 3 and the axis of the drilling component 2. When the lifting part 12 provided with the drilling component 2 is located in the middle of the base 11, the lifting part 12 provided with the clamping component 3 is located at one end of the base 11, and the clamping component 3 is located above the storage component 4. When the lifting part 12 provided with the drilling component 2 slides towards the other end of the base 11, the lifting part 12 provided with the clamping component 3 is located in the middle of the base 11. After drilling, through the sliding connection between the lifting part 12 and the base 11, the clamping component 3 can be located above the drill hole, which is convenient for clamping the core sample. Moving the two lifting parts 12 again can reset the clamping component 3, making the clamping component 3 located above the storage component 4, which is convenient for placing the core sample into the storage component 4 for the next measurement and detection.

The fixed ends of the lifting cylinders 422 are fixedly connected to the housing 421, and the movable ends of the lifting cylinders 422 pass through the housing 421. A lifting disc is arranged at the movable ends of the lifting cylinders 422. A plurality of storage frames 443 are arranged on the storage rack 44, which can store multiple core samples and compare the thicknesses of multiple core samples. The storage frames 443 correspond to the lifting cylinders 422. A lifting window 441 is opened at the bottom of the storage frame 443. The lifting disc can move upward through the lifting window 441. The diameter of the lifting window 441 is smaller than the diameter of the core sample. When placing the core sample on the clamping component 3, the lifting cylinders 422 can be started to smoothly receive the core sample and avoid damage to the core sample. Four observation windows are equally spaced circumferentially on the storage frame 443, and a scale is arranged on one side of the observation window, which can directly understand the thicknesses at different positions in the circumferential direction of the core sample and facilitate subsequent calculation of the core sample thickness.

[0047] A plurality of the clamping members 43 are arranged at intervals. A plurality of limiting grooves 4211 are arranged at intervals at the upper end of the housing 421. The limiting grooves 4211 correspond to the clamping members 43. A plurality of limiting windows 442 are formed in the middle of the storage rack 44. The limiting windows 442 correspond to the clamping members 43. The clamping members 43 pass through the limiting windows 442 formed in the storage rack 44 and are inserted into the limiting grooves 4211. The clamping member 43 includes a limiting plate 431 and a limiting spring 432. The limiting groove 4211 is slidably connected to the lower end of the limiting plate 431. Two limiting plates 431 are provided and symmetrically arranged. The two limiting plates 431 are telescopically and slidably connected through a sleeve and a connecting rod. The limiting spring 432 is arranged between the two limiting plates 431. The limiting spring 432 is sleeved outside the sleeve and the connecting rod. The upper end of the limiting plate 431 passes through the limiting window 442 and is slidably connected to the limiting window 442. Limiting strips 4311 are arranged on the opposite sides of the two limiting plates 431. The lower surface of the limiting strip 4311 abuts against or separates from the upper surface of the storage rack 44.

[0048] When the storage rack 44 is clamped to the lifting member 42, the limiting strip 4311 is located above the storage rack 44 and the lower surface thereof contacts the upper surface of the storage rack 44, so that the storage rack 44 can be fixed on the lifting member 42. When the two limiting plates 431 move towards the middle of the storage rack 44, the storage rack 44 can be disassembled and can be moved as a whole, which is convenient for the next inspection. At the same time, the order of the core samples is prevented from being confused, and a new storage rack 44 can be placed to continue the next sampling measurement, improving the construction efficiency. The lifting cylinder 422 can have various driving modes such as electric, pneumatic and hydraulic.

[0049] When a highway engineering construction thickness detection device is in use, first push the detection device to a suitable position, then rotate the support member 15 so that the positioning piece contacts the ground to fix the position of the detection device. Start the piston cylinder 185 corresponding to the drilling component 2 to make the corresponding spline sleeve 187 cooperate with the mating gear 183, and then start the drive motor 184 to drive the corresponding lead screw 125 to rotate, so that the drill cylinder 21 contacts the ground. Then start the drilling motor 22 and continue to operate the drive motor 184 at the same time to make the drill cylinder 21 penetrate into the ground. Judge the drilling depth according to the scale on the corresponding slide bar 121. After reaching the appropriate depth, reverse the operation of the drive motor 184 to make the drill cylinder 21 leave the ground, turn off the drilling motor 22, and the piston cylinder 185 corresponding to the drill cylinder 21 acts in the reverse direction, so that the spline sleeve 187 corresponding to the drill cylinder 21 disengages from the mating gear 183. Then start the telescopic rod 16 to move the lifting part 12 towards the pusher 14, and at the same time make the clamping component 3 located above the core sample. Start the piston cylinder 185 corresponding to the clamping component 3, and start the drive motor 184 again to make the chuck 32 penetrate into the drill hole. Then start the telescopic cylinder 33 to clamp the core sample. At the same time, start the vacuum pump 52 to extract the sewage in the drill hole. Reverse the operation of the drive motor 184 to make the clamping component 3 rise. Start the axial flow fan 62, stretch the air duct 63, and rotate the elbow 64 to blow air on the drill hole and the core sample, so that the clamping component 3 rises to a certain position. Act in the reverse direction on the telescopic rod 16 to reset the lifting part 12. Start the storage motor 414 to move the position of the storage rack 44. Sequentially start the corresponding lifting cylinders 422, and start the drive motor 184 again to make the core sample fall on the lifting plate. Lower the lifting plate, and place the core sample in the corresponding storage box 443 according to the sampling order. After the drive motor 184 makes the clamping component 3 rise and reset, the corresponding piston cylinder 185 acts in the reverse direction, so that the spline sleeve 187 corresponding to the clamping component 3 disengages from the mating gear 183. Observe the thickness of the core sample and record multiple groups of data. Then move the device to the next sampling point and repeat the above actions. When the storage box 443 is full, move two limit plates 431 towards the middle of the storage rack 44, disassemble the storage rack 44, place a new storage rack 44, and continue the sampling detection.
