A bridge deck flatness detection device

Abstract

The invention relates to a bridge deck roughness detection device. The problem that the marking at fixed length cannot be performed since the wheel track is tedious in marking when monitoring the flatness can be effectively solved. The technical scheme is as follows: the detection device comprises a flat car body, and a paint box is fixedly arranged on a flat plate, and the paint box is connectedwith a line-drawing device; a marking device located at the rear side of the line drawing device is arranged on the flat plate; the marking device comprises a disk arranged at the center of an upper end surface of the flat plate, the rotation of the wheels of the flat car can drive the disk to intermittently rotate, and bulges and push rods are arranged on the outer edge of the disk; a transversesecond support plate is arranged at the front side of each push rod, the left and right locations of the second support plate are adjustable, an outer end of each second support plate is connected with a vertical and horizontal rotating plate, the rotating plate can rotate and reset, and the rotating plate is connected with an inclined brush; the push rods can move left and right in a reciprocating way, and push the rotating plate to rotate in the reciprocating way, so that the brush can brush the ground along a left-right direction. The roughness detection in most engineering can be satisfied, the convenience is provided, and the accuracy of the detection data is ensured.

Description

technical field [0001] The invention relates to the field of bridge construction detection, in particular to a bridge surface flatness detection device. Background technique [0002] Pavement roughness mainly reflects the smoothness of the profile curve of the pavement profile. Except for special needs, the wheel track (80-100cm from the lane line) on the side of the roadway should be used as the standard position for continuous measurement. [0003] According to the "Pavement Flatness Test Regulations and Technical Standards for Flatness Detectors": [0004] The calibration of the responsive flatness detector is as follows: [0005] (1) More than five road sections are generally selected for calibration, and the road conditions should be different; theoretically speaking, the longer the length of the road, the better, generally hoped to be between 150m and 250m. [0006] (2) Before calibration, the road surface should be cleaned up, usually with a broom to clean the road...
