Description

Technical Field

[0001] The utility model relates to the field of road surface detection, in particular to a positioning structure for road surface flatness detection. Background Art

[0002] The positioning structure for road surface flatness detection is a structure for detecting and positioning the detection device. Before the detection device detects the road surface flatness, the detection device needs to be installed vertically and parallelly so that the detection device can detect the road surface flatness. Therefore, the positioning structure is an indispensable part of road surface flatness detection, and the detection device can be accurately installed and used vertically and parallelly. When using the existing positioning structure for road surface flatness detection, it is generally necessary to manually adjust the installation position to a vertical and parallel state after the structure is placed. However, manual adjustment is cumbersome, and it is impossible to quickly find the vertical and parallel position to position the detection device, which is inconvenient for road surface flatness detection. In addition, after finding the vertical and parallel position, it is necessary to lock the position. When used in different positions of the structure, repeated locking and disassembly are required, which also makes it impossible to quickly position and fix it for use. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 3 As shown, a positioning structure for road surface flatness detection includes a main mounting plate 1, a fixing ring 2 is fixedly installed at the center of the main mounting plate 1, a rotating sphere 3 is movably installed on the inner side of the fixing ring 2, a suspension rod 4 is welded to the bottom of the rotating sphere 3, a detection mounting head 5 is fixedly installed on the lower end of the suspension rod 4, a support frame 6 is fixedly installed on the upper end of the main mounting plate 1, an internal thread ring 7 is fixedly installed on the upper end of the support frame 6, a lifting screw 8 is installed on the internal thread of the internal thread ring 7, a rotating handle 9 is welded on the upper end of the lifting screw 8, a positioning pressing plate 10 is movably installed on the lower end of the lifting screw 8, an extension connecting frame 11 is fixedly installed on the four corners of the main mounting plate 1, a support rod 13 is fixedly installed on the lower end of the extension connecting frame 11, and a supporting foot pad 14 is movably installed on the lower end of the support rod 13.

[0019] In this embodiment, the rotating sphere 3 is arranged concentrically with the fixing ring 2 and rotates around the inside thereof. The rotating sphere 3 penetrates the fixing ring 2 , and the fixing ring 2 plays the role of movably mounting the rotating sphere 3 .

[0020] In this embodiment, the lifting screw 8 passes through the internal thread ring 7 , and the rotating handle 9 is located above the lifting screw 8 . The lifting screw 8 is driven by the rotating handle 9 to rotate and rise and fall in the internal thread ring 7 .

[0021] In this embodiment, the bottom surface of the positioning pressure plate 10 is designed as an arc-shaped structure. The positioning pressure plate 10 is located above the rotating sphere 3. The positioning pressure plate 10 is used to press the rotating sphere 3 for positioning.

[0022] In this embodiment, the center of the suspension rod 4 is vertically arranged with the center of the circle of the fixing ring 2 , and the suspension rod 4 and the detection mounting head 5 are both located below the main body mounting plate 1 .

[0023] In this embodiment, the extension connecting frame 11 is sleeved on the outside of the main mounting plate 1, and an adjustment slot 12 is opened inside the extension connecting frame 11. A screw runs through the inside of the adjustment slot 12, and the screw is threadedly connected to the main mounting plate 1. The screw plays the role of locking and fixing the extension connecting frame 11. Before the screw is tightened, the extension connecting frame 11 moves around the screw through the adjustment slot 12 to achieve the effect of position adjustment.

[0024] It should be noted that the utility model is a positioning structure for detecting the flatness of a road surface. When in use, four supporting foot pads 14 are placed at the detection position to fix the entire structure. When the detection position is tilted, the main mounting plate 1 is also tilted. The influence of gravity is used to keep the suspension rod 4 vertically downward, thereby driving the rotating sphere 3 to rotate inside the fixed ring 2. Therefore, when the positioning structure is placed at any angle, the rotation of the rotating sphere 3 can be used to make the suspension rod 4 vertically downward. After the suspension rod 4 is vertical, the lifting screw 8 is driven to rotate by rotating the handle 9. The lifting screw 8 moves up and down through the threaded connection with the internal threaded ring 7. Therefore, the lifting screw 8 drives the positioning pressure plate 10 at the lower end to squeeze downward on the top of the rotating sphere 3, and the rotating sphere 3 and the suspension rod 4 are pressed and positioned. Then the detection device is installed on the detection mounting head 5 at the lower end of the suspension rod 4 for use to achieve vertical and parallel positioning before flatness detection.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
