Abstract

The invention discloses a flatness detection device for road engineering construction, and relates to the technical field of road flatness detection devices. The whole frame is of a rectangular frame structure, a handle rod is welded and fixed to the bottom of the rear end of the frame through two Z-shaped supporting plates, two transverse supporting rods are symmetrically welded to the interior of the frame, and an electric control box is installed on the transverse supporting rod at the front end in a locking mode. A swing frame is rotatably mounted in the middle of the frame, and four longitudinally-supported six-edge positioning shafts are welded to supporting rods on the left side and the right side of the frame in a front-back symmetry mode. Two racks are symmetrically installed on the four hexagonal positioning shafts in a sliding mode, and two positioning holes are formed in the middle sections of the two racks at intervals. Through meshing power transmission of the two racks, the four swing rods and the swing frame can be synchronously driven to swing, open and close, and the problems that the swing rods and the five six-edge sliding shafts need to be subjected to swing, open and close step by step before and after use, and use is troublesome and inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of road smoothness detection devices, in particular to a road smoothness detection device for road engineering construction. Background technique [0002] Road roughness is the main indicator of road performance evaluation. It reflects the comfort and driving quality of the road surface. It is of great significance in the evaluation of road service performance. Road roughness detection requires a road engineering construction. [0003] Although the existing flatness detection device can shrink and deform to a certain extent, it is limited by the fact that there are few parts that can shrink, resulting in a small shrinkage limit, and the support still occupies a large area, which is not easy to carry and transfer, and there are many missing parts. Most of the parts cannot be linked and synchronously driven when they are unfolded, and they need to be manually unfolded step by step, which is troublesome and inc...
