Description

Technical Field

[0001] The invention relates to the technical field of asphalt flatness control, in particular to a detection device for measuring flatness during asphalt construction. Background Art

[0002] During the asphalt construction process of road engineering, asphalt flatness is one of the important main control items of the road, and the flatness quality control is particularly important. Asphalt paving is a linear project with a long length and a large workload. In addition, the flatness of asphalt must be measured during the paving process before the asphalt is completely hardened, and the unqualified positions must be re-rolled in time. If ordinary rulers and feeler gauges are used for measurement and control, the surveyor needs to squat down to measure the flatness. The measurement length is huge, and the surveyor needs to squat down and stand up many times, back and forth. The toxicity of asphalt and the high temperature of asphalt will cause great discomfort to people, and even asphalt poisoning, so the flatness control is often lax, resulting in unqualified, and if the asphalt hardens after the temperature drops, it will not be able to be rolled flat. Summary of the invention

[0026] In the present invention, a preferred implementation is: after the asphalt paving of the road surface is completed, the construction personnel can adjust the height of the support bracket to adapt to the height of the construction personnel, so that when the subsequent construction personnel measure the flatness of the asphalt road surface, the construction personnel can easily push and pull the measuring ruler 1, and prevent the construction personnel from squatting to measure the flatness of the asphalt and breathing the toxic gas emitted by the heating of the asphalt, which affects the life safety of the construction personnel. By pushing and pulling the measuring ruler 1, the displacement sensor 2 in the measuring ruler 1 measures the flatness of the asphalt road surface, thereby facilitating the subsequent construction personnel to measure. The displacement sensor 2 can measure the flatness change value up and down. When encountering an uneven road surface, the roller is notified to roll in time before the temperature has not completely dropped to the point where rolling is impossible.

[0027] Further, the support bracket includes: a support rod 4 rotatably disposed on the top of the measuring ruler 1 and a telescopic rod 3 rotatably disposed between the support rod 4 and the measuring ruler 1, and the height of the support rod 4 can be adjusted by adjusting the length of the telescopic rod 3. Preferably, the length of the telescopic rod 3 can be adjusted so that the support rod 4 and the measuring ruler 1 are at different angles, so that the height of the support rod 4 is adjustable, which is convenient for construction workers to use.

[0028] Furthermore, a first ear plate is formed on the measuring ruler 1, and a second ear plate is formed on the support rod 4 corresponding to the first ear plate. By setting a pin in the first ear plate and the second ear plate, the support rod 4 can be rotatably set on the measuring ruler 1.

[0029] Furthermore, a third ear plate is formed on the measuring ruler 1, and a fourth ear plate is formed on the telescopic rod 3 corresponding to the third ear plate. By setting a pin in the third ear plate and the fourth ear plate, the telescopic rod 3 can be rotatably set on the measuring ruler 1.

[0030] Furthermore, a hand-held handle 5 is provided on the top of the support rod 4. The construction personnel can pull or push the support bracket through the hand-held handle 5.

[0034] Furthermore, the width of the contact end is smaller than the width of the mounting groove. By making the width of the contact end smaller than the width of the mounting groove, the displacement sensor 2 is prevented from being stuck in the mounting groove.

[0035] Furthermore, both ends of the contact end are chamfered, so as to prevent the displacement sensor 2 from being stuck in the installation groove.

[0036] The following is an explanation of the use of a detection device for measuring flatness during asphalt construction according to the present invention.

[0037] After the asphalt paving of the road is completed, the construction workers can adjust the height of the support bracket to adapt to the height of the construction workers, so that when the subsequent construction workers measure the flatness of the asphalt road surface, the construction workers can easily push and pull the measuring ruler 1, and prevent the construction workers from squatting to measure the flatness of the asphalt and breathing the toxic gas emitted by the heating of the asphalt, which affects the life safety of the construction workers. By pushing and pulling the measuring ruler 1, the displacement sensor 2 in the measuring ruler 1 measures the flatness of the asphalt road surface, thereby facilitating the subsequent construction workers to measure. The displacement sensor 2 can measure the flatness change value up and down. When the road surface is uneven, the data is transmitted to the display through the displacement sensor 2, and the display issues an early warning. The construction workers promptly notify the roller to roll before the temperature has not completely dropped to the point where rolling is impossible.
