Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a road surface flatness detection device. Background Technique

[0002] Road construction involves activities such as construction or repair on roads, including road surface paving, facility construction, and subgrade reinforcement, in order to improve the bearing capacity and stability of the road. After road construction, a detection device is usually used to detect the flatness of the road to ensure normal vehicle driving.

[0003] A road surface flatness detection device with the publication number of CN218373200U takes a detection vehicle as the main body. At both ends of the bottom side of the detection vehicle, rollers are symmetrically arranged. A driving motor is arranged between the rollers. A storage box is arranged at the top end of the side of the detection vehicle. An activity slot is opened at the middle position inside the detection vehicle. A limiting plate is fixed on the side of the activity slot. A top column is slidably installed in the limiting plate. An auxiliary wheel is fixed at the bottom end of the top column. One end of the top column is rotatably connected to a driving rod, and a driven rod is fixed at one end of the driving rod. This detection device drives the rollers to rotate through the driving motor, so that the detection vehicle moves on the road surface. At this time, when the auxiliary wheel moves on the uneven ground, it will open the sealing plate in a lifting manner, so that the dust falls on the uneven position, thus facilitating subsequent identification and repair.

[0004] There are still problems in the above-mentioned road surface flatness detection device. When the detection device is used, the auxiliary wheel cannot fully cover the road surface at the bottom side of the detection vehicle, so that it cannot detect the road that the auxiliary wheel has not passed through, resulting in omissions in the detection results of the detection device. Therefore, a road surface flatness detection device is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, when the detection devices on the market are used, the auxiliary wheel cannot fully cover the road surface at the bottom side of the detection vehicle, so that it cannot detect the road that the auxiliary wheel has not passed through, resulting in omissions in the detection results of the detection device. The utility model proposes a road surface flatness detection device.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A road surface flatness detection device described in the utility model includes a box body; a detection mechanism is arranged inside the box body, a fixing mechanism is arranged on the side of the box body, a sealing mechanism is arranged inside the detection mechanism, and a double-layer partition board is fixed inside the box body.

[0007] The detection mechanism includes a double-layer partition. A cavity is formed inside the double-layer partition. A hollow cylinder is slidably inserted inside the double-layer partition. A roller is fixed to the bottom end of the hollow cylinder, and the rollers are arranged staggeredly on the bottom side of the box body. A limiting plate is fixed on the circumferential surface of the hollow cylinder. A spring is fixedly connected between the limiting plate and the double-layer partition. Through holes are symmetrically formed on the circumferential surface of the hollow cylinder. The hollow cylinder is slidably inserted through the bottom side of the box body. The spring is sleeved on the hollow cylinder. The through holes are located on both sides of the cavity. The inside of the hollow cylinder is communicated with the inside of the cavity through the cooperation of the through holes. Through the staggeredly arranged hollow cylinders and rollers, the road surface covered by the box body is fully detected to prevent omission. At the same time, it can be marked with liquid paint, which is more eye-catching and not easy to erase.

[0008] The fixing mechanism includes a hollow cylinder. Fixing holes are formed on the circumferential surface of the top side of the hollow cylinder. A hopper is fixed to the side surface of the box body. The bottom end inside the hopper is communicated with the inside of the cavity. A fixing rod is slidably inserted inside the box body. The fixing rod is slidably inserted inside the fixing hole. One end of the fixing rod passes through the box body and is fixed with a rectangular plate, and the rectangular plate is buckled on the side surface of the box body. Round holes are formed on both sides of the double-layer partition. It is fixed through the cooperation of the fixing rod and the fixing hole, which is convenient for disassembly and installation and simple to use. At the same time, it can prevent the liquid paint from leaking during transportation.

[0009] The sealing mechanism includes a round hole. A sealing groove is formed on the circumferential surface inside the round hole. A sealing ring is fixed inside the sealing groove. The sealing ring is slidably sleeved on the hollow cylinder, and the sealing ring is in close fit with the surface of the hollow cylinder. Directional wheels are fixed at the four corners of the bottom side of the box body. A push rod is fixed at one end of the top side of the box body. The sealing ring can prevent the liquid paint from leaking during the detection process and improve the detection accuracy of the device.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Through the structural design of a road surface flatness detection device of the present utility model, by setting a detection mechanism, the cavity inside the double-layer partition is filled with liquid paint, and the rollers are arranged staggeredly on the bottom side of the box body. At this time, the rollers will pass through the road surface covered by the box body. If there are uneven places on the road surface, at this time, the rollers will drive the hollow cylinder to lift and move, so that the through holes are moved to the inside of the cavity, making the inside of the hollow cylinder communicate with the inside of the cavity, and enabling the liquid paint inside to be transported to the inside of the hollow cylinder. At this time, the liquid paint is discharged from the bottom side of the hollow cylinder to mark the uneven places on the road surface, which is convenient for subsequent repair, and solves the problem of inaccurate detection results of the existing detection device.

[0012] 2. Through the structural design of a road surface flatness detection device, with the structure of the fixing mechanism, the hopper can replenish liquid pigment into the inner side of the cavity, and at the same time, the remaining amount of the liquid pigment inside can be directly observed. When storing or operating the detection device, insert the fixing rod into the inner side of the box body, and make the fixing rod sequentially penetrate into the fixing holes on the circumferential surfaces of each hollow cylinder. At this time, the position of the hollow cylinder is fixed, preventing the liquid pigment from leaking from the bottom side of the hollow cylinder, making the detection device more convenient to use.

A roller 8 is fixed at the bottom end of the hollow cylinder 4, and the rollers 8 are arranged in a staggered manner on the bottom side of the box body 1. A limiting plate 5 is fixed on the circumferential surface of the hollow cylinder 4. A spring 6 is fixedly connected between the limiting plate 5 and the double-layer partition 2. Through holes 7 are symmetrically formed on the circumferential surface of the hollow cylinder 4. The hollow cylinder 4 is slidably inserted through the bottom side of the box body 1. The spring 6 is sleeved on the hollow cylinder 4. The through holes 7 are located on both sides of the cavity 3. The inside of the hollow cylinder 4 is communicated with the inside of the cavity 3 through the cooperation of the through holes 7; When working, when encountering the problem that the existing detection device is prone to omission, through the structure of the detection mechanism, the cavity 3 inside the double-layer partition 2 is filled with liquid pigment. The rollers 8 are arranged in a staggered manner on the bottom side of the box body 1. At this time, the rollers 8 will pass through the road surface covered by the box body 1. If there are uneven places on the road surface, at this time, the rollers 8 will drive the hollow cylinder 4 to move up and down, so that the through holes 7 are moved to the inside of the cavity 3, making the inside of the hollow cylinder 4 communicate with the inside of the cavity 3, and enabling the liquid pigment inside to be transported to the inside of the hollow cylinder 4. At this time, the liquid pigment is discharged from the bottom side of the hollow cylinder 4 to mark the uneven places on the road surface, facilitating subsequent repair.

[0023] Please refer to Figure 3 As shown in the figure, the fixing mechanism includes the hollow cylinder 4. Fixing holes 11 are formed on the circumferential surface of the top side of the hollow cylinder 4. A hopper 12 is fixed on the side surface of the box body 1. The bottom end inside the hopper 12 is communicated with the inside of the cavity 3. A fixing rod 9 is slidably inserted inside the box body 1. The fixing rod 9 is slidably inserted inside the fixing holes 11. One end of the fixing rod 9 passes through the box body 1 and is fixed with a rectangular plate 10, and the rectangular plate 10 is buckled on the side surface of the box body 1. Circular holes 201 are formed on both sides of the double-layer partition 2; When working, when encountering the problem that the liquid pigment inside the detection device is prone to leakage, through the structure of the fixing mechanism, the liquid pigment can be replenished into the cavity 3 through the hopper 12, and at the same time, the remaining amount of the liquid pigment inside can be directly observed. When storing or operating the detection device, the fixing rod 9 is inserted inside the box body 1, so that the fixing rod 9 is sequentially inserted inside the fixing holes 11 on the circumferential surface of each hollow cylinder 4. At this time, the position of the hollow cylinder 4 is fixed, preventing the liquid pigment from leaking from the bottom side of the hollow cylinder 4 and making the detection device more convenient to use.

[0024] Please refer to Figure 4As shown, the sealing mechanism includes a round hole 201. A sealing groove 13 is formed on the inner circumferential surface of the round hole 201. A sealing ring 14 is fixed in the sealing groove 13.

Four corners of the bottom side of the box body 1 are fixed with directional wheels 15, and one end of the top side of the box body 1 is fixed with a push rod 16. During operation, when there is a problem that the liquid pigment inside the detection device leaks and affects the accuracy of the detection result, by the structure of the sealing mechanism, the push rod 16 is pushed, so that the box body 1 moves on the road surface in cooperation with the directional wheels 15, thereby detecting the flatness of the road surface passed by. When the road surface is flat, the sealing ring 14 is in close fit with the surface of the hollow cylinder 4 to prevent the liquid pigment from leaking. If the road surface is uneven, the through hole 7 on the surface of the hollow cylinder 4 moves to the inside of the sealing ring 14, thereby making a mark to prevent the detection result from being inaccurate due to pigment leakage during the detection process.

[0025] Please refer to Figure 5 As shown, a cylinder body 17 is evenly inserted and installed inside the double-layer partition 2. The cylinder body 17 is slidably inserted through the bottom side of the box body 1. During operation, when there is a problem that the hollow cylinder 4 is not convenient to clean, by the structure of the cylinder body 17, the two ends of its inner side are communicated. At this time, water can be filled into the top side of the cylinder body 17 to wash the inside of the cylinder body 17, thereby facilitating the regular maintenance of the detection device and prolonging the service life of the device.

[0026] Working principle: Road construction involves activities such as construction or repair on roads, including pavement laying, facility construction, and subgrade reinforcement, in order to improve the bearing capacity and stability of the road. After road construction, a detection device is usually used to detect the flatness of the road to ensure normal vehicle driving. When the existing detection device is in use, the auxiliary wheels cannot fully cover the bottom side of the detection vehicle, so it cannot detect the road that the auxiliary wheels do not pass through, resulting in omissions in the detection results of the detection device. To solve this problem, by setting up a detection mechanism and a fixing mechanism, the box body 1 is placed on the detection road surface, the rectangular plate 10 is pulled to extract the fixing rod 9, thus releasing the fixation of the hollow cylinder 4. The inner cavity 3 of the double-layer partition 2 is filled with liquid pigment. The push rod 16 is pushed, so that the box body 1 moves on the road surface in cooperation with the directional wheels 15. The rollers 8 are arranged in a staggered manner on the bottom side of the box body 1. At this time, the rollers 8 will pass through the road surface covered by the box body 1, thereby detecting the flatness of the road surface passed by them. When the road surface is flat, the sealing ring 14 is closely attached to the surface of the hollow cylinder 4 to prevent liquid pigment leakage. If there are unevenness on the road surface, at this time, the roller 8 will drive the hollow cylinder 4 to move up and down, so that the through hole 7 is moved to the inside of the cavity 3, making the hollow cylinder 4 communicate with the inside of the cavity 3, and the liquid pigment inside is transported to the inside of the hollow cylinder 4. At this time, the liquid pigment is discharged from the bottom side of the hollow cylinder 4 to mark the unevenness on the road surface, facilitating subsequent repair. After the detection is completed, the fixing rod 9 is inserted back into the side of the box body 1 and inserted and installed inside each fixing hole 11 to fix the position of the hollow cylinder 4 for the next detection use, solving the problem of inaccurate detection results of the existing detection device.
