Description
Technical Field
The utility model belongs to the technical field of check out test set, concretely relates to highway wave form roof beam steel guardrail crossbeam center height detection device.
Background
The corrugated beam steel guardrail is a traffic safety facility product for protecting and isolating an expressway, is necessary guarantee for safe driving of the expressway, plays a role in preventing vehicles from driving out of lanes, reducing the injury degree of drivers and protecting roadside objects, and provides safety guarantee for safe and efficient driving of the expressway vehicles. In order to fully play the safety guarantee role of the corrugated beam steel guardrail, the construction quality is strictly ensured in guardrail installation, and the important thing is that the central height of a cross beam meets the requirements of design and specification.
The conventional wave beam steel guardrail beam center height detection equipment is roughly divided into two types. One method is that the combination of a horizontal ruler and a steel ruler is simply adopted for detection, the horizontal ruler is adopted to lead out the central point of the beam, then the steel ruler is used for measuring the height of the beam, the detection is completed by two persons, one person operates and places the horizontal ruler, and the other person operates and uses the steel ruler to measure the distance from the center of the beam to the road surface, so that the method is time-consuming and labor-consuming to a great extent, and errors caused by manual operation are larger; particularly, in an actual detection field, because the two wave surfaces of the wave-shaped beam are in arc line transition, the common horizontal ruler is square, the horizontal ruler cannot be accurately placed at the center of the beam during detection, and in this case, errors are inevitable. And the horizontal ruler and the steel ruler are only used for measurement in a way that testers cooperate with each other to hold the horizontal ruler and the steel ruler in a hand-held mode, and the horizontal ruler and the steel ruler cannot be well fixed, so that the horizontal ruler and the vertical ruler cannot be completely guaranteed, the fact that the horizontal ruler and the steel ruler do not shake in the measurement process is difficult to guarantee, and the measurement result is affected by the change of any link.
The other type is an adjustable height steel frame with a base, a transverse frame is used for positioning, and a vertical frame is used for measuring, but the adjustable height steel frame is not suitable for a detection field, on one hand, the height of the transverse frame needs to be continuously adjusted, time is consumed, a horizontal device is generally arranged on the base, even if the base is horizontal in use, the horizontal of the transverse frame is difficult to ensure, and a large monitoring error can be caused; on the other hand, in order to ensure the level of the cross frame as much as possible, the equipment needs to be assembled on site during each measurement, the cross frame needs to be disassembled after the measurement is finished, the operation is complicated, and the efficiency is low.
In a word, the existing method and device for detecting the central height of the corrugated beam steel guardrail beam in the actual engineering have larger defects and defects, and the comprehensive improvement and perfection are imminent.
