Description

Technical Field

[0001] This utility model relates to a road deflection detection device, specifically a highway testing device for road deflection detection, belonging to the field of road deflection detection technology. Background Technology

[0002] Road deflection testing is a technical method for assessing the load-bearing capacity and structural health of a road. It is mainly used to detect the degree of vertical deformation of the road surface under vehicle load. Currently, some deflection testing devices are mainly made of stainless steel or alloy materials and are divided into two or three sections.

[0003] Chinese Patent Publication CN217818556U discloses a highway testing device for road surface deflection detection. By pulling the handle, the second connecting frame and the slider slide within the groove provided in the first connecting frame, allowing the second connecting frame to unfold and merge with the first connecting frame. Then, the first connecting frame and the third connecting frame are installed and merged through the first opening, the second opening, and the threaded bolt.

[0004] The aforementioned patent uses the cooperation of a slider and a groove to slide the first connecting frame and the second connecting frame together. In practical applications, it has been found that if the manufacturing precision is insufficient, the gap may be too large or too small. If it is too large, it may loosen and affect the accuracy of the test results. If it is too small, it may cause the device to slide unsmoothly and increase the difficulty of use.

[0005] Furthermore, while the aforementioned patents offer advantages in terms of ease of assembly and disassembly, their structures are relatively complex, and there is room for improvement in terms of optimized storage. Therefore, this paper proposes a highway testing device for detecting pavement deflection. Utility Model Content

The frame includes a connecting frame A and a connecting frame B, both of which are fixed with a level. A vertical rod is threadedly connected to the top surface of the left end of the connecting frame A, and a frustum is fixed to the upper end of the vertical rod.

[0008] The measuring component includes a bracket, the bracket includes a chassis, a column is fixed to the top surface of the chassis, the measuring component also includes a movable seat slidably connected to the column, a first fixed block and a second fixed block are threadedly connected to the movable seat, a dial indicator is slidably connected to the movable seat, and the position of the second fixed block corresponds to the dial indicator.

[0009] A connecting assembly is provided between the connecting frame A and the connecting frame B. The connecting assembly includes a threaded sleeve fixed to the right end of the connecting frame A, and the connecting assembly also includes a first threaded rod fixed to the left end of the connecting frame B. The first threaded rod and the threaded sleeve are threadedly connected.

[0010] The connecting frame A and connecting frame B are provided with a support and storage assembly.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0024] Please see Figures 1-4 The present invention proposes the following implementation scheme: a highway test and inspection device for road surface deflection detection, including a frame 1 and a measuring component 4. The frame 1 includes a connecting frame A101 and a connecting frame B102. A level 103 is fixed on both the connecting frame A101 and the connecting frame B102. The level 103 can be used to determine the horizontal state of the connecting frame A101 and the connecting frame B102.

[0025] A vertical rod 104 is threadedly connected to the top surface of the left end of the connecting bracket A101. A frustum 105 is fixed to the upper end of the vertical rod 104. The vertical rod 104 and the frustum 105 are used to cooperate with the dial indicator 405 to provide a suitable testing height for the dial indicator 405.

[0026] Please refer to this carefully. Figure 1 and Figure 2The measuring component 4 includes a bracket 401, which includes a chassis 4011. A column 4012 is fixed on the top surface of the chassis 4011. The measuring component 4 also includes a movable seat 402 that is slidably connected to the column 4012. A first fixing block 403 and a second fixing block 404 are threadedly connected to the movable seat 402.

[0027] The movable seat 402 can be fixed by rotating the first fixing block 403, thereby adjusting the height of the movable seat 402. The dial indicator 405 can be fixed by the second fixing block 404, thereby adjusting the height of the dial indicator 405. The dial indicator 405 is slidably connected to the movable seat 402, and the position of the second fixing block 404 corresponds to that of the dial indicator 405.

[0028] Please refer to this carefully. Figure 1 and Figure 3 A connecting component 2 is provided between the connecting frame A101 and the connecting frame B102. The connecting component 2 includes a threaded sleeve 201 fixed to the right end of the connecting frame A101. The connecting component 2 also includes a first threaded rod 202 fixed to the left end of the connecting frame B102. The first threaded rod 202 and the threaded sleeve 201 are threadedly connected.

[0029] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 The connecting frame A101 and the connecting frame B102 are provided with a support and storage component 3. The support and storage component 3 includes a support threaded hole 307 opened at the bottom of the connecting frame A101 and the connecting frame B102. A second threaded rod 301 is internally threaded in the support threaded hole 307. A fixing post 302 is fixed at the lower end of the second threaded rod 301.

[0030] The lower end of the fixed column 302 is threadedly connected to a third threaded rod 303. By rotating the third threaded rod 303, the height of the connecting frame A101 or the connecting frame B102 can be adjusted, and the connecting frame A101 and the connecting frame B102 can be kept in a horizontal state in conjunction with the level 103.

[0031] The lower end of the third threaded rod 303 is rotatably connected to a base plate 304. An anti-slip pad 308 is fixed on the bottom surface of the base plate 304. The outer contour of the anti-slip pad 308 is cylindrical. The anti-slip pad 308 can improve the anti-slip effect. A threaded hole 305 is opened on the connecting frame A101, and an insertion hole 306 is opened on the connecting frame B102. The inner diameter of the insertion hole 306 is larger than the outer diameter of the second threaded rod 301.

[0032] Working principle: In use, the connecting frame A101 and connecting frame B102 are first connected by threaded sleeve 201 and first threaded rod 202. The threaded connection provides higher fixation stability and is more convenient for installation and disassembly. Then, the second threaded rod 301 is screwed into the support threaded hole 307. The connecting frame A101 and connecting frame B102 are supported by the second threaded rod 301, fixed column 302, third threaded rod 303 and base plate 304. Then, the height of the moving seat 402 is adjusted by the first fixed block 403. After the adjustment is completed, the position of dial indicator 405 is adjusted by the second fixed block 404.

[0033] When the device needs to be stored after testing, first rotate the fixing post 302. The fixing post 302 will drive the second threaded rod 301 to rotate out of the support threaded hole 307. Then, stack the connecting frame A101 and the connecting frame B102 together. When the second threaded rod 301 moves through the insertion hole 306 to the position of the storage threaded hole 305, the fixing post 302 can be rotated to screw the second threaded rod 301 into the storage threaded hole 305, thereby realizing the storage of the connecting frame A101, the connecting frame B102, the second threaded rod 301, the fixing post 302, the third threaded rod 303, and the base plate 304, improving the convenience of storage.
