Description

Technical Field

[0001] This utility model relates to the field of deflection detection technology, and more specifically, to a deflection detection device that is easy to move. Background Technology

[0002] Deflection refers to the vertical deformation of a roadbed or pavement under a specified load. The amount of deflection caused by pavement rebound not only reflects the overall stiffness and strength of the roadbed and pavement structure, but also has a certain intrinsic relationship with the service condition of the pavement.

[0003] Existing municipal road deflection testing equipment typically requires manual operation by staff to raise and lower the deflection meter during testing. This process is time-consuming and labor-intensive, leading to reduced work efficiency. Furthermore, lowering the deflection meter before testing makes it difficult to inspect different locations on the road surface, causing inconvenience and poor testing results. In addition, most existing deflection testing equipment is manually raised and cannot be moved. The current method of using a manual dial indicator for reading is prone to inaccurate readings. Therefore, a more portable deflection testing device is needed to solve this problem. Utility Model Content

[0010] As a preferred embodiment of this utility model, the connecting rod has a screw hole on its side end, and the screw hole is locked by a locking screw.

A screw hole is opened at the side of the connecting rod 12 and locked by a locking screw 14. The ratio of the front end to the rear end of the deflectometer body 1 is 2:1. A pusher 24 is fixedly installed on the deflectometer body 1.

[0024] In this embodiment, during the deflection detection process, the side of the deflection meter body 1 is placed on the measuring point. The deflection is automatically recorded by the displacement sensor 15 by gently tapping the deflection meter body 1 with a finger. Finally, the road deflection detection value is calculated by the computer and displayed on the display 11, realizing automatic data display.

When the universal wheel 21 is needed to move, the bottom of the fixed seat 4 can be moved. During the detection process, the universal wheel 21 can be retracted to ensure stability. During the detection process, the side of the deflection meter body 1 is placed on the measuring point.
