Problems solved by technology

The existing method of detecting the rebound deflection value of the Beckman beam mainly has the following problems: at the beginning of each road section test, the loading vehicle needs to be parked on the testing road section, and after the L1 value is measured, the loading vehicle moves forward for a certain distance. After a certain distance, you still have to stop on the test road section, that is to say, the whole measurement process is a static measurement process, which leads to the existing deflection value measurement method can only be used in road conditions where there are no other vehicles running, such as When measuring the deflection value of the road, it is necessary to close the road in advance, which greatly affects the traffic and cannot be applied to the road conditions that have been opened and used by other vehicles

Abstract

The invention relates to a deflection beam for measuring deflection value and a road deflection value measuring device. The deflection beam includes a beam body, and the beam body is provided with outriggers that are outside the range of influence of the corresponding deflection during use. Corresponding to the measuring rod whose length corresponding to the left wheel and / or the right wheel extends along the front-to-rear direction, the measuring rod is provided with at least three displacement measurement components arranged at equal intervals along the front-to-rear direction, and each displacement measurement component is respectively a position The front end displacement measuring part, the rear end displacement measuring part and the middle displacement measuring part between the head end displacement measuring part and the tail end displacement measuring part. The invention provides a deflection beam capable of measuring the road deflection value during the running process of a loading vehicle and a road deflection value measuring device using the deflection beam.

Description

technical field [0001] The invention relates to a deflection beam for measuring deflection in the field of road deflection measurement and a road deflection measuring device using the deflection beam. Background technique [0002] The deflection value refers to the deformation of the roadbed / pavement before and after the load acts on the roadbed / pavement, and the calculation unit is 1 / 100 mm. [0003] Rebound deflection refers to the vertical rebound deformation value produced by the subgrade and road surface wheel gap position under the specified standard axle load B22-100. The Beckman beam is a common device for measuring the rebound deflection value. The Beckman beam is made of aluminum alloy and includes a beam body and a support for supporting the beam body. The beam body on the front side of the support is called the forearm , the beam body on the rear side of the support is called the rear arm, usually the length ratio of the forearm to the rear arm is 2:1, the end o...
