Problems solved by technology

When the inspection vehicle moves along the direction of the bridge, the lifting trolley must be retracted, which brings a lot of inconvenience to the continuous inspection work. At the same time, the lifting trolley is located at the cantilever end on both sides, and the upper part shakes a lot when working on it, and the safety is also poor.

Abstract

The invention discloses a beam bottom inspection vehicle capable of passing through a pier. The beam bottom inspection vehicle comprises a portal frame, a middle truss and a side truss, wherein the middle truss and the side truss are arranged at the two sides of the portal frame. The middle truss is connected with the portal frame through a pin shaft; the upper portion of one end of the side trussis hinged to the portal frame through a pin shaft, and the whole side truss can rotate around the hinged hinge point. The lower portion of one end of the side truss is supported on the portal frame through a follow-up oil cylinder, the middle truss is obliquely pulled on the portal frame through an inhaul cable, and the other end of the side truss is obliquely pulled on the portal frame through astroke-adjustable inhaul cable. The problem of continuous work of the beam bottom inspection vehicle capable of passing through piers is well solved, and the inspection efficiency is also greatly improved; and meanwhile, a lifting trolley is reduced at the cantilever end, the cantilever end load is reduced, and the running safety of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of bridge inspection equipment, in particular to a beam bottom inspection vehicle capable of passing bridge piers. Background technique [0002] The bridge inspection vehicle is a special equipment for bridge inspection. The main form of the existing under-bridge inspection vehicle is a suspended walking inspection vehicle. The suspension type walking inspection vehicle under the bridge can be divided into two types: those that can pass the bridge pier and those that cannot pass the bridge pier. [0003] The traditional under-bridge suspension inspection vehicle that can pass through bridge piers must be equipped with lifting trolleys at both ends to fully inspect the inclined web of the bridge. When the inspection vehicle moves along the direction of the bridge, the lifting trolley must be retracted, which brings a lot of inconvenience to the continuous inspection work. At the same time, the lifting trolley...
