Device and method for detecting center height of corrugated beam steel guardrail crossbeam

Abstract

The present invention relates to the technical field of highway engineering quality testing equipment, in particular to a corrugated beam steel guardrail crossbeam center height testing device, comprising: There are two groups, and they are slidingly arranged on the same surface of the base plate; the jaw driving part is connected with the two jaw components, and drives the two jaw components to approach or move away from each other at the same time; the horizontal rod is fixed on the other side of the base plate, and the laser rangefinder Set on a horizontal pole, the laser distance meter is used to measure the distance from its measuring point to the road surface. The base plate is fixed on the corrugated beam steel guardrail crossbeam by means of the two claw components arranged opposite to the base plate, and the claw driver simultaneously drives the two claw components to converge towards the center synchronously, and the laser rangefinder set on the horizontal bar , which improves the accuracy and efficiency of distance measurement. The invention also claims a detection method for the height of the center height of the crossbeam of the corrugated beam steel guardrail.

Description

technical field [0001] The invention relates to the technical field of highway engineering quality detection equipment, in particular to a device and method for detecting the center height of a corrugated beam steel guardrail crossbeam. Background technique [0002] The corrugated guardrail is a kind of combined corrugated plate movable steel guardrail at the opening of the highway central divider. The guardrail is composed of two corrugated steel guardrails and two columns fixedly clamped between them. Between two corrugated steel guardrails. When the vehicle collides with it, because the corrugated steel guardrail has good crashworthiness and energy absorption, it is not easy to be crashed, and at the same time, it can play a good role in protecting the vehicle and the passengers. In order to give full play to the safety guarantee function of the corrugated beam steel guardrail, the construction quality of the guardrail should be strictly guaranteed. Among them, the heigh...

Problems solved by technology

[0004] However, there are many errors in the above-mentioned measurement methods. On the one hand, because the beam is divided into two-wave beams and three-wave beams, the method of determining the center of the beam close to the naked eye cannot guarantee the accuracy of center confirmation. On the other hand, manual hand-held level measurement cannot Fully guarantee the level of the measurement and the verticality of the steel ruler. Errors in multiple links will cause a great impact on the final measurement results, and the accuracy of the construction quality inspection of the corrugated beam steel guardrail center cannot be guaranteed.
