Description

Technical Field

[0001] This utility model belongs to the field of road construction smoothness detection technology, specifically relating to a multifunctional road construction smoothness detection device. Background Technology

[0002] Road construction refers to the entire process of planning, designing, constructing, maintaining, and managing roads, as well as the engineering entities involved. Road surface smoothness refers to the deviation of the longitudinal unevenness of the road surface, which is an important indicator in road evaluation and road construction acceptance. It mainly reflects the smoothness of the longitudinal profile curve of the road surface. When the longitudinal profile curve of the road surface is relatively smooth, it indicates that the road surface is relatively smooth or has relatively good smoothness, and vice versa. A good road surface requires good smoothness. Therefore, after the road surface construction is completed, smoothness testing is required, which necessitates the use of smoothness testing devices.

[0003] For example, patent CN220116975U discloses a road construction flatness testing device, which includes a mobile frame. A testing component is provided on one side of the mobile frame. The testing component includes an electric telescopic rod, and a testing plate is fixedly connected to the output end of the electric telescopic rod.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model allows construction workers to activate the second motors on both sides of the upper part of the vehicle.

During this process, the workers can start the water pump, which, guided by the second connecting pipe, the first connecting pipe, and the telescopic hose, can transport water from the water tank to the outer pipe. Since the outer pipe is connected to the inner pipe through a connecting pipe, the water can be sprayed out from the spray heads located on opposite sides of the outer and inner pipes. This allows for simultaneous spraying and dust suppression on both the road section and the surrounding area cleaned by the cleaning components, reducing the amount of floating dust generated by the cleaning components and minimizing its impact on the environment. Subsequently, workers can replace or clean the cleaning components installed below the mounting plate using the screw grooves and bolt rods. It is portable and practical. Next, workers can activate the infrared ranging sensor and the data acquisition and analysis instrument. By pushing the mobile frame, the infrared ranging sensor measures the distance between the vehicle and the ground, transmitting the measured data to the data acquisition and analysis instrument for data collection and analysis, thereby determining whether the road is level.

[0019] Construction workers first use a mobile vehicle to move the entire device to the road to be inspected. Then, they start the first motor to rotate the transmission screw. At this time, the screw sleeve that interacts with the screw will carry the connecting frame and the lower frame below it to descend in coordination with the guide sleeve and guide rod until the two cleaning parts under the connecting plate at the bottom of the lower frame can fit against the road surface.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a multifunctional road construction flatness testing device, and its structural schematic diagram is shown below. Figures 1 to 4As shown, the device includes a mobile frame 1. A lifting mechanism 2 is installed on the upper and lower edges of one side of the mobile frame 1. The lifting mechanism 2 includes a lower frame 29, and a connecting plate 3 is fixed to the end of the lower frame 29.

Infrared ranging sensors 10 are installed on the lower end of the detection plate 9. The data acquisition and analysis instrument 7 and the infrared ranging sensors 10 are electrically connected. The lifting mechanism 2 includes a mounting box 21, which is fixed to the upper side of the mobile frame 1. An inner panel 2 is fixed to the upper part of the interior of the mounting box 21. 2. A first motor 23 is installed on one side above the inner panel 22. The output end of the first motor 23 is connected to a transmission screw 24. A screw sleeve 25 is screwed around one side of the transmission screw 24. A connecting frame 26 is fixed inside the screw sleeve 25. A guide sleeve 27 is fixed at the other end of the connecting frame 26. A guide rod 28 is fixed on one side below the inner panel 22 to guide the movement of the guide sleeve 27. Lower frames 29 are fixed on both sides of the lower end of the connecting frame 26. The construction personnel first use the mobile frame 1 to move the entire device to the road to be inspected. Then, the first motor 23 is started to make the transmission screw 24 rotate. At this time, the screw sleeve 25, which interacts with the screw, will carry the connecting frame 26 and the lower frame 29 below it to descend in coordination with the guide sleeve 27 and the guide rod 28 until the two cleaning parts 414 below the connecting plate 3 connected to the bottom of the lower frame 29 can fit against the road surface.

[0028] The cleaning mechanism 4 includes a sweeping component 41, which is installed below the connecting plate 3. The sweeping component 41 includes a second motor 411, which is located on both sides of the upper center of the connecting plate 3. The output ends of the two second motors 411 are connected to transmission rods 412, and the ends of the two transmission rods 412 are connected to a mounting plate 413. A sweeping component 414 is installed at the bottom of the mounting plate 413, and screw grooves 415 are provided on both sides of the mounting plate 413 and the sweeping component 414. A bolt rod 416 is screwed into the middle of the screw groove 415. The sweeping component 41 is symmetrically distributed along the central axis of the connecting plate 3. A dust suppression component is installed on the inner and outer sides of the connecting plate 3 and on the upper side of the mobile frame 1. 42. The dust suppression component 42 includes an inner tube 421, which is disposed on the inner wall of the connecting plate 3. An outer tube 422 is disposed on the outer side of the connecting plate 3. Fixing sleeves 423 are provided around the inner tube 421 and the outer tube 422 respectively. A connecting pipe 424 is connected to the opposite sides of the inner tube 421 and the outer tube 422 on the same side. A telescopic hose 425 is connected to the upper side of one side of the outer tube 422. Spray heads 426 are provided on different sides of the inner tube 421 and the outer tube 422 respectively. The spray heads 426 are evenly distributed along the opposite sides of the inner tube 421 and the outer tube 422, and the spray angle of the spray heads 426 is downward. A first connecting pipe 42 is connected to the upper side of the mobile frame 1. 7. A water pump 428 is connected to the end of the first connecting pipe 427, and a second connecting pipe 429 is connected to the other end of the water pump 428. The telescopic hose 425 is connected to the first connecting pipe 427. When the construction personnel start the second motors 411 on both sides above, the corresponding transmission rods 412 can drive the mounting plate 413 and the sweeping parts 414 installed below it to sweep the road surface. During this process, the personnel start the water pump 428, which, guided by the second connecting pipe 429, the first connecting pipe 427 and the telescopic hose 425, can transport the water in the water tank 5 to the outer pipe 422. Since the outer pipe 422 is connected to the inner pipe 421 through the connecting pipe 424, the water can flow along the outer pipe 422. Sprays are emitted from the spray head 426, which is located opposite to the inner tube 421. This allows for simultaneous spraying and dust suppression on both the road section and the surrounding area cleaned by the sweeping component 414. This reduces the amount of floating dust generated by the sweeping component 414, which can negatively impact the environment and personnel. Subsequently, personnel can replace or clean the sweeping component 414 installed below the mounting plate 413 using the screw groove 415 and bolt rod 416. It is portable and practical. Next, personnel can activate the infrared ranging sensor 10 and the data acquisition and analysis instrument 7. Personnel push the mobile frame 1, and the infrared ranging sensor 10 measures the distance between itself and the ground. The measured data is then transmitted to the data acquisition and analysis instrument 7 for data collection and analysis, thereby determining whether the road is level.

[0029] Working principle: Construction personnel first move the entire device to the road to be inspected using a mobile frame 1. Then, they start the first motor 23 to rotate the transmission screw 24. At this time, the screw sleeve 25, which interacts with the screw, will lower the connecting frame 26 and its lower frame 29, guided by the guide sleeve 27 and guide rod 28, until the two cleaning components 414 below the connecting plate 3 connected to the bottom of the lower frame 29 can fit against the road surface. Next, the construction personnel start the second motors 411 on both sides above. Under the transmission of the corresponding transmission rod 412, the mounting plate 413 and the cleaning components 414 installed below it can perform cleaning operations on the road surface. During this process, the personnel start the water pump 428, which, guided by the second connecting pipe 429, the first connecting pipe 427, and the telescopic hose 425, can transport water from the water tank 5 to the outer mounting pipe 422. Furthermore, due to the outer... The outer pipe 422 is connected to the inner pipe 421 via the connecting pipe 424, so the water can be sprayed out through the spray heads 426 located on opposite sides of the outer pipe 422 and the inner pipe 421. This allows for simultaneous spraying and dust suppression of the road cleaning section and the surrounding area of ​​the sweeping component 414, reducing the amount of floating dust caused by the sweeping component 414 and thus minimizing its impact on personnel and the environment. Subsequently, personnel can replace or clean the sweeping component 414 installed below the mounting plate 413 using the screw groove 415 and bolt rod 416. It is portable and practical. Next, personnel can activate the infrared ranging sensor 10 and the data acquisition and analysis instrument 7, and push the mobile frame 1. The infrared ranging sensor 10 measures the distance between itself and the ground, and transmits the measured data to the data acquisition and analysis instrument 7 for data collection and analysis, thereby determining whether the road is level.
