Description

Technical Field

[0001] The utility model relates to the field of road and bridge detection, and particularly to a road and bridge flatness detection device. Background Technique

[0002] The flatness of the road surface refers to the deviation value of the longitudinal unevenness of the road surface. The flatness of the road surface is an important index in road surface evaluation and road construction acceptance, mainly reflecting the flatness of the longitudinal section profile curve of the road surface. When the longitudinal section profile curve of the road surface is relatively smooth, it means that the road surface is relatively flat, or the flatness is relatively good, otherwise it means that the flatness is relatively poor. The commonly used measurement methods include the fixed-length straightedge method, the section description method and the bump integration method.

[0003] After retrieval, in the prior art, there is a "road and bridge construction road surface flatness detection device" with the publication number of "CN215252184U". This device has protruding points on the surface of the bracket to facilitate the staff to observe whether the ground is flat. However, during the detection process, there may be little difference in local flatness, resulting in the staff being unable to clearly observe the flatness difference, which will affect the accuracy of the detection.

[0004] Therefore, a road and bridge flatness detection device is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a road and bridge flatness detection device to solve the above problems, improving the problem that the staff cannot clearly observe the flatness difference, which will affect the detection accuracy.

[0006] The utility model realizes the above purpose through the following technical solutions. A road and bridge flatness detection device includes: a bottom plate, and a plurality of bottom wheels are fixedly connected to the lower end of the bottom plate; a detection mechanism, and the detection mechanism is arranged above the bottom wheels; wherein, the detection mechanism includes a horizontal component fixedly connected to the upper end of the bottom plate, an indicating component is arranged inside the horizontal component, the indicating component is installed on the upper end of the bottom plate, and the lower end of the indicating component extends below the bottom plate.

[0007] Preferably, the horizontal component includes a plurality of liquid storage tubes fixedly connected to the upper end of the bottom plate. A communicating pipe is connected between one side of the liquid storage tubes, and the communicating pipe is fixedly connected to the surface of the adjacent liquid storage tubes. A plastic rod is arranged inside the liquid storage tubes, a plastic plate is ball-jointed at the upper end of the plastic rod, and an indicating plate is fixedly connected to the upper end of the plastic plate. In this device, a reference effect can be formed through the indicating plate, and the plastic plate can be kept as horizontal as possible. When detecting the bridge deck, even if the whole is inclined, it can be clearly observed.

[0008] Preferably, the indicating component includes a connecting shaft fixedly connected to the upper end of the bottom plate. A sliding frame is rotatably connected to the surface of the connecting shaft. A telescopic rod is fixedly connected to the lower end of the sliding frame. A right-angle frame is fixedly connected to the telescopic end of the telescopic rod. A roller is rotatably connected to the lower end of the right-angle frame. When a local inclination occurs, the roller can be attached to the road surface to drive the sliding frame to swing significantly.

[0009] Preferably, a ball joint seat is fixedly connected to the lower end of the plastic plate. The ball joint seat is ball-jointed with the upper end of the plastic rod. When the ball joint seat keeps the plastic rod being pushed by the internal hydraulic pressure of the liquid storage tube well, the ball joint seat can keep the plastic plate being supported relatively horizontally.

[0010] Preferably, a piston is fixedly connected to the lower end of the plastic rod. The piston is slidably connected to the inner wall of the liquid storage tube. When the liquid flows in the liquid storage tube, it will push the piston to cause the plastic rod to rise and fall.

[0011] Preferably, the indicating component further includes an indicating rod rotatably connected to the surface of the horizontal component. A cross bar is fixedly connected to the inner wall of the indicating rod. The inner wall of the sliding frame is slidably connected to the surface of the cross bar. The length of the sliding frame is greater than the lengths of the telescopic rod and the right-angle frame. When the right-angle frame is inclined under the action of the roller, it will cause the sliding frame to show an obvious offset.

[0012] Preferably, a spring is fixedly connected to the surface of the telescopic rod. The other end of the spring is fixedly connected to the telescopic end of the telescopic rod. The spring makes the right-angle frame drive the two rollers to always be attached to the ground.

[0013] The beneficial effects of the present utility model are:

[0014] 1. The above road and bridge flatness detection device can, under the action of the detection mechanism, detect the uneven areas on the road surface locally, achieve the ability to move on a flat road surface, and when encountering an inclined road surface, at this time, it can be shown on the indicator board through the indicating rod, and the flatness difference can be magnified, so that the staff can observe it clearly, ensuring the detection effect;

[0015] 2. When detecting on the road surface, when there is a local flatness difference, the telescopic rod and the spring can be used to keep the roller attached to the ground. At the same time, with the cooperation of the sliding frame and the indicating rod, the smaller flatness difference can be magnified and shown at the indicator board, which is convenient for construction workers to observe.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-5 shown, a road and bridge flatness detection device includes: a bottom plate 1, and a plurality of bottom wheels 2 are fixedly connected to the lower end of the bottom plate 1; a detection mechanism 3, and the detection mechanism 3 is arranged above the bottom wheels 2; wherein, the detection mechanism 3 includes a horizontal component 31 fixedly connected to the upper end of the bottom plate 1, an indicator component 32 is arranged inside the horizontal component 31, the indicator component 32 is installed on the upper end of the bottom plate 1, and the lower end of the indicator component 32 extends below the bottom plate 1;

[0024] As Figure 1 , Figure 2 and Figure 3 shown, the horizontal component 31 includes a plurality of liquid storage pipes 311 fixedly connected to the upper end of the bottom plate 1, a connecting pipe 312 is connected between the liquid storage pipes 311 on one side, the connecting pipe 312 is fixedly connected to the surface of the adjacent liquid storage pipes 311, a plastic rod 314 is arranged inside the liquid storage pipes 311, a plastic plate 316 is ball-jointed to the upper end of the plastic rod 314, an indicator plate 317 is fixedly connected to the upper end of the plastic plate 316, a ball hinge seat 315 is fixedly connected to the lower end of the plastic plate 316, the ball hinge seat 315 is ball-jointed to the upper end of the plastic rod 314, a piston 313 is fixedly connected to the lower end of the plastic rod 314, and the piston 313 is slidably connected to the inner wall of the liquid storage pipe 311;

[0025] During use, the bottom plate 1 is pushed to drive the horizontal component 31 to move as a whole. At this time, if there is a tilt, the liquid inside the side liquid storage tube 311 will keep the two pistons 313 at a relatively horizontal height under the action of gravity, and then, under the auxiliary action of the hydraulic pressure, the plastic plate 316 will be kept relatively horizontal through the plastic rod 314. If the flatness of the indicator component 32 and the horizontal component 31 is the same, the position indicated by the indicator rod 324 at the roller 327 should remain unchanged. At the same time, if there is a local unevenness, the indicator rod 324 will be significantly offset at the roller 327, which is convenient for the operator to check;

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the indicating assembly 32 includes a connecting shaft 321 fixedly connected to the upper end of the bottom plate 1, a sliding frame 323 is rotatably connected to the surface of the connecting shaft 321, a telescopic rod 322 is fixedly connected to the lower end of the sliding frame 323, a right angle frame 326 is fixedly connected to the telescopic end of the telescopic rod 322, a roller 327 is rotatably connected to the lower end of the right angle frame 326, and the indicating assembly 32 also includes an indicating rod 324 rotatably connected to the surface of the horizontal assembly 31, a cross bar 325 is fixedly connected to the inner wall of the indicating rod 324, the inner wall of the sliding frame 323 is slidably connected to the surface of the cross bar 325, a spring 328 is fixedly connected to the surface of the telescopic rod 322, and the other end of the spring 328 is fixedly connected to the telescopic end of the telescopic rod 322;

[0027] When the roller 327 moves, the spring 328 cooperates with the telescopic rod 322, so that the right-angle frame 326 drives the two rollers 327 to fit the ground, and local areas become uneven. At this time, the rollers 327 at the front and rear ends fit the ground, causing the sliding frame 323 to deviate. At the same time, the cross bar 325 is moved, causing the indicator rod 324 to deviate significantly at the indicator plate 317, making it easier for the operator to observe the defective area of ​​the road surface.

[0028] When the utility model is in use, during the operation, the bottom plate 1 drives the whole horizontal component 31 to move. Under the action of gravity, the liquid inside the liquid storage pipe 311 will keep a relatively horizontal effect through the plastic rod 314 and the plastic plate 316. Then, the indicating rod 324 indicates that the position at the roller 327 should remain unchanged. If there is a local uneven situation, when the roller 327 moves along, through the cooperation of the spring 328 and the telescopic rod 322, the right-angle frame 326 drives the two rollers 327 to fit the ground. When there is unevenness in the local area, at this time, the front and rear rollers 327 are in contact with the ground, the sliding frame 323 is displaced, and at the same time, the dialing cross bar 325 moves, and the indicating rod 324 has an obvious displacement at the indicating board 317, which will cause an obvious displacement of the indicating rod 324 at the roller 327, facilitating the operator to check.

[0029] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
