Pavement levelness detection device for road construction

Abstract

The invention discloses a road surface levelness detection device for road construction. The device comprises a main body, a detection mechanism and a control panel, supporting frames are fixed to thetwo ends of the bottom of the main body, an electric telescopic rod is fixed to the bottom of the main body, a pressure sensor is fixed to the bottom of a mounting plate, and a movable frame is slidably connected to the lower portion of a fixed frame; and the control panel is fixed to the top of the main body, and a mounting frame is fixed to the lower portion of the third spring. The road surface levelness detection device for road construction is provided with a pressure sensor, a base plate and a rotating roller, the rotating roller below the fixing frame makes contact with the ground whenthe main body is pushed, and vibration generated by rotation of the rotating roller attached to the road surface is reduced under the elastic action of a first spring; when a protrusion is encountered, the rotating roller drives the movable frame to contract to enable the base plate at the top of the movable frame to make contact with the pressure sensor below the fixed frame, the pressure sensortransmits signals to the control panel at the top of the body to prompt workers, and the detection speed is increased while precision is improved.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular to a road surface level detection device for road construction. Background technique [0002] With the continuous construction of highways in our country, the quality of highways is also constantly improving. The quality of highways will directly affect driving speed, safety and transportation costs. High-grade highways with good pavement can ensure high-speed, safe and comfortable driving. Driving can also save more transportation costs and give full play to the functions of high-grade roads. Therefore, it is necessary to measure whether there are protrusions or depressions on the road. Most of the existing road surface level detection devices generate vibration by pushing the detection vehicle and cooperating with the rotating roller. The road surface is tested, and the vibration generated by the detection vehicle while pushing will affect the detection accurac...

Problems solved by technology

[0003] The purpose of the present invention is to provide a road surface level detection device for road construction, to solve the problem that the detection accuracy of the existing road surface level detection device proposed in the above background technology is relatively poor, and it is inconvenient to measure the gravel and gravel on the front road surface at the same time. Dust is cleaned, and most of the bumps and depressions on the road are marked manually, which is troublesome to use, and after a long period of use, dirt and dust will adhere to the surface of the rotating roller, which will affect the measurement accuracy and poor practicability.
