Deflection measuring device for road detection

Abstract

The invention discloses a deflection measuring device for road detection. The deflection measuring device comprises a base, rotating discs are fixed at the front end and the rear end of the base, moving mechanisms are fixedly mounted at the lower ends of the rotating discs, limiting mechanisms for limiting the rotating discs are arranged on the base, a threaded rod is rotatably connected to the upper end of the base, and the threaded rod is parallel to the base. An adjusting wheel is fixedly connected to the middle of the threaded rod, threads opposite in screwing direction are arranged on the threaded rod on the two sides of the adjusting wheel, the two threads are in threaded connection with threaded sleeves, fixing plates used for fixing the Beckman beam are arranged at the two ends of the threaded rod, the fixing plates and the threaded sleeves are rotationally connected through connecting rods, and a graduated scale is further arranged on the upper surface of the base and parallel to the threaded rod. According to the deflection measuring device for road detection, rollers are arranged, so that detection personnel directly pushes the base to advance conveniently, compared with a traditional carrying mode of carrying by shoulders and hands, more physical strength is saved, and damage to the deflection measuring tool in the transportation process can be effectively reduced.

Description

Technical field[0001]The present invention relates to the field of highway detection, and more particularly to a curved measuring device for highway detection.Background technique[0002]The curved test is based on the control test of the roadbed construction such as the highway, bridge tunnel. By the comparative test and related analysis of the roadbed for different sections and different soils, the FWD detection subgrade is proposed. Control indicator.[0003]The steps of the Beckmann beam method are as follows: In the test section arrangement, the measuring point is generally arranged on the trajectory of the driving lane, 20m per lane, with a white paint or chalk, and record the mesh mileage, position. If the situation is special, the test point can be properly encrypted according to the specific situation. When there is condition, you can use two benders at the left and right two-wheeled belt simultaneous measurement. Determination with "advancement unloading method", the rear whee...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the Beckman beam is relatively long and inconvenient to move during the road detection in the prior art, and it is easy to cause damage to the Beckman beam during the transportation process, and proposes a road detection The advanced deflection measuring device can facilitate transportation and reduce the difficulty of placement
