Semi-automatic and portable nondestructive detection equipment and detection method for bearing capacity of movable handrail

Abstract

The invention provides a semi-automatic and portable nondestructive detection device and method for the bearing capacity of a movable handrail, and the device comprises a pedestal platform, a main support, an auxiliary support, a horizontal force loading device, a contact device, and a data collection and processing device. By controlling the device detection height through a hydraulic oil cylinder, a servo hydraulic oil cylinder carries out horizontal force grading loading and works in cooperation with a base, the auxiliary support, the contact device and the data collecting and processing device, the bearing capacity of horizontal handrails of a bridge sidewalk and a pedestrian overpass can be detected, the bearing capacity of handrails of upstairs and downstairs of the pedestrian overpass can be detected, single-point loading detection and two-point loading detection can be carried out, and the whole instrument is convenient to move, has little influence on traffic, is relatively simple in structure, and can realize semi-automatic detection.

Description

technical field [0001] The invention belongs to the technical field of railing bearing capacity detection, and in particular relates to a horizontal thrust bearing capacity detection device and detection method of bridge sidewalk railings or pedestrian bridge guardrails. Background technique [0002] With the rapid development of urban construction and road connectivity, more and more small and medium-sized bridges and pedestrian bridges have been put into the urban road network, making pedestrian travel more convenient. The construction of small and medium-sized bridge sidewalks and urban pedestrian bridges has good traffic and social benefits for increasing the speed of vehicle circulation, realizing the separation of people and vehicles, and improving the quality of urban walking. Therefore, the correct detection and evaluation of the safety status of bridge pedestrian railings and pedestrian bridge railings to ensure the safety of pedestrians is crucial to improving the ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are not many researches on the bearing capacity detection devices of bridge railings in China. On-site railings detect heavy objects (mostly heavy vehicles) at the back as the rear support reaction force, which affects traffic, moves clumsily, and requires multiple people to assist and work together, which is inefficient.
