Description

Technical Field

[0001] The utility model relates to the technical field of road construction inspection, in particular to a device for inspecting the hardening degree of a road surface during road construction. Background Art

[0002] During road construction, in order to lay asphalt later, it is generally necessary to flatten and compact the dirt road surface. Only when the dirt road surface reaches a certain hardness can asphalt be laid. The existing dirt road surface hardening degree test is generally done manually by tapping with a chisel. The workers' arms will ache after tapping the road surface for a long time, which increases the workload. Therefore, a device that can assist manual pavement hardness testing is needed.

[0003] The prior art discloses a device for testing the degree of hardening of a road surface during road construction. This device performs a hardening degree detection operation by having a detection cone block move downward under the action of its own gravity to hammer the road surface. This makes the road surface detection operation simpler and more convenient, helps to detect the road surface more quickly, and effectively improves the road surface detection efficiency.

[0004] However, this device still has some defects. In actual use, the inspection cone block of this device is fixed on the positioning frame, and only fixed points can be inspected at a time. When other points need to be inspected, the inspection device needs to be moved continuously. Frequent movement of the inspection device will consume more time, resulting in a long cycle for the entire inspection process.

[0005] Therefore, it is necessary to provide a road construction pavement hardening degree inspection device to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a road construction pavement hardening degree inspection device that can realize the inspection device to move left and right in an area, thereby eliminating the need to frequently move the inspection device, thereby improving the inspection efficiency.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A device for inspecting the degree of hardening of a road surface during road construction comprises: a mobile vehicle and an adjusting component, wherein the adjusting component is arranged at the upper end of the mobile vehicle, the adjusting component comprises: a fixed frame, a threaded rod is arranged at the inner end of the fixed frame, a driving motor is arranged at one end of the threaded rod, and an inspection component is arranged on the threaded rod, the inspection component comprises: a moving seat, a hydraulic cylinder is fixedly arranged at the upper end of the moving seat, the output end of the hydraulic cylinder is connected to a lower pressure plate, fixed rods are arranged at both ends of the lower pressure plate, and an inspection hammer is arranged at the center of the lower pressure plate.

[0012] Preferably, a positioning hole is provided at the bottom of the fixing frame, and a threaded hole is provided on the moving block, and the fixing frame is fixed to the moving block by a pre-tightening bolt.

[0013] Preferably, the mobile vehicle further comprises: fixing bolts, which are symmetrically arranged at the four corners of the mobile vehicle, and a support block is arranged at the lower end of the fixing bolt. The utility model has the following beneficial effects:

[0014] (1) The utility model can realize the left and right movement of the inspection component by using multiple parts in the adjustment component. The inspection component can be quickly and accurately moved to the designated test point through the adjustment component, which reduces the time and labor intensity required for manual movement of the equipment, thereby speeding up the entire inspection process.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-4As shown, the road construction pavement hardening degree inspection device provided by the utility model includes: a mobile vehicle 100 and an adjustment component 200, the adjustment component 200 is arranged at the upper end of the mobile vehicle 100, the adjustment component 200 includes: a fixed frame 201, a threaded rod 203 is arranged at the inner end of the fixed frame 201, a driving motor 202 is arranged at one end of the threaded rod 203, and an inspection component 300 is arranged on the threaded rod 203, and the inspection component 300 includes: a moving seat 302, a hydraulic cylinder 301 is fixedly arranged at the upper end of the moving seat 302, and the hydraulic cylinder 301 outputs The ends are connected to the lower pressure plate 305, and fixing rods 308 are set at both ends of the lower pressure plate 305. The fixing rods 308 are connected to the limit plates 307, and an inspection hammer 306 is set at the center of the lower pressure plate 305. In actual use, the staff drives the mobile vehicle 100 to the inspection area through the handle 101, and then fixes the mobile vehicle 100. When the mobile vehicle 100 is fixed, the hydraulic cylinder 301 is started, and the piston rod inside the hydraulic cylinder 301 is connected to the connecting block 309. The telescopic action of the piston drives the lower pressure plate 305 to move up and down through the connecting block 309. The connecting block 309 is connected to the lower pressure plate 305 by positioning bolts. Since the inspection hammer 306 is fixedly installed at the lower end of the lower pressure plate 305, the inspection hammer 306 moves downward. When one point inspection is completed, the drive motor 202 is controlled. Through the drive of the drive motor 202, the threaded rod 203 is rotated, thereby controlling the movable seat 302 on the threaded rod 203 to move left and right. Through the left and right movement of the movable seat 302, the inspection component 300 moves left and right as a whole. When it moves to another inspection point, the drive is stopped and then a second inspection is performed on it.

[0027] By cooperating with multiple parts within the set adjustment component 200, the inspection component 300 can be moved left and right. The inspection component 300 can be quickly and accurately moved to the designated test point through the adjustment component 200, reducing the time and labor intensity required for manual movement of the equipment, thereby speeding up the entire inspection process. At the same time, through the precise control of the threaded rod 203, it can be ensured that the position of each inspection remains consistent, reducing errors caused by human factors and improving the accuracy and reliability of the inspection results.

[0028] Second embodiment:

[0029] like Figure 4-5 As shown, sliders are provided at both ends of the lower pressure plate 305, and a guide plate 303 is provided at the lower end of the movable seat 302. The guide plates 303 are symmetrically arranged, and the lower pressure plate 305 slides up and down in the limit groove 304 provided on the guide plate 303. In actual use, when the lower pressure plate 305 moves downward, the lower pressure plate 305 moves up and down within the range of the limit groove 304 provided on the guide plate 303 through the sliders provided at both ends.

[0030] By setting up the lower pressure plate 305 in coordination with the guide plate 303, in actual use, the guide plate 303 can not only ensure that the inspection hammer 306 moves along a predetermined vertical path, reducing errors caused by oblique forces or offsets, thereby improving the accuracy of detection, but also provide stable support for the inspection hammer 306, so that it will not swing or deviate when moving downward, thereby ensuring the operational stability of the equipment.

[0031] Third embodiment:

[0032] like Figure 3-4 As shown, a support rod 204 is provided at the upper end of the fixed frame 201, and the support rod 204 is symmetrically arranged, and the support rod 204 passes through the movable seat 302. In actual use, when the movable seat 302 moves left and right on the threaded rod 203, the support rod 204 passing through the movable seat 302 can increase the overall rigidity of the structure, reduce shaking or deviation during the movement, and ensure that the movable seat 302 moves smoothly along a predetermined path. At the same time, the support rod 204 can serve as a guide to reduce the direct friction between the threaded rod 203 and the movable seat 302, thereby extending the service life of the threaded rod 203 and the movable seat 302.

[0033] Fourth embodiment:

[0034] like Figure 2 , Figure 6 As shown, a moving assembly 400 is also provided at the lower end of the fixed frame 201, and the moving assembly 400 includes: a fixed seat 401, a slot is provided on the fixed seat 401, an adjusting rod 402 is provided in the slot, a moving block 404 is sleeved on the adjusting rod 402, a slot is provided on the moving block 404, and the slot has the same diameter as the fixed frame 201. In actual use, when it is necessary to inspect the longitudinal point, the staff starts the motor on the placement frame 104 to rotate the adjusting rod 402 in the fixed seat 401, and the rotation of the adjusting rod 402 drives the internal moving block 404 to move in the fixed seat 401, and the movement of the moving block 404 drives the fixed frame 201 to move in the slot provided in the fixed seat 401.

[0035] By using the mobile component 400 in conjunction with the adjustment component 200, it is possible to easily reach different locations for inspection, which is suitable for road hardening degree inspection of various sizes and shapes. The operator can quickly adjust the position of the inspection component 300 to improve work efficiency, reduce the time and energy consumed by frequent movement of large equipment, and achieve a more detailed inspection grid to ensure that every part of the road surface is inspected, avoid missed inspections, and improve the reliability of the overall inspection.

[0036] Fifth embodiment:

[0037] like Figure 6As shown, a positioning hole is provided at the bottom of the fixing frame 201, and a threaded hole is provided on the moving block 404. The fixing frame 201 is fixed to the moving block 404 by a pre-tightening bolt 403. In actual use, the fixing frame 201 is first placed in the slot on the moving block 404 so that the holes of the two are aligned, and then it is fixed by the pre-tightening bolt 403.

[0038] By providing a notch on the moving block 404 and using the pre-tightening bolt 403, quick installation and disassembly of the fixing frame 201 is achieved, which facilitates subsequent maintenance of the device on the fixing frame 201 by the staff. At the same time, by using the pre-tightening bolt 403, the stability of the fixing frame 201 and the moving block 404 can be enhanced.

[0039] Sixth embodiment:

[0040] like Figure 1-2 As shown, the mobile vehicle 100 also includes: a fixing bolt 102, which is symmetrically arranged at the four corners of the mobile vehicle 100, and a support block is arranged at the lower end of the fixing bolt 102. In actual use, when the staff moves the mobile vehicle 100 to the area that needs to be inspected, the staff rotates the fixing bolt 102. Through the rotation of the fixing bolt 102, the fixing block under the fixing bolt 102 is tightly against the ground, ensuring that during the inspection process, the mobile vehicle 100 is prevented from moving and affecting the inspection.

[0041] Working principle: The staff drives the mobile vehicle 100 to the inspection area through the handle 101, and then fixes the mobile vehicle 100. When the mobile vehicle 100 is fixed, power is supplied through the power supply box 103, and the hydraulic cylinder 301 is started, so that the lower pressure plate 305 moves downward, and the inspection hammer 306 moves downward. When the inspection of a point is completed, the driving motor 202 is controlled at this time. Through the drive of the driving motor 202, the threaded rod 203 is rotated, thereby controlling the moving seat 302 on the threaded rod 203 to move left and right. Through the left and right movement of the moving seat 302, the inspection component 300 moves left and right as a whole. When it moves to another inspection point, the drive is stopped, and then a second inspection is performed on it. When it is necessary to inspect the longitudinal point, the staff starts the motor on the placement frame 104 to make the adjusting rod 402 rotate in the fixed seat 401. Through the rotation of the adjusting rod 402, the fixed frame 201 is driven to move in the slot provided in the fixed seat 401.

[0042] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
