Lower detection and inspection instrument for high-speed railway vehicle

Abstract

The invention relates to an instrument for inspecting the bottom of a high-speed railway vehicle, in particular to a lower detection and inspection instrument for the high-speed railway vehicle. The instrument comprises a detection and inspection instrument main body, a convex mirror with a mirror seat is arranged above the detection and inspection instrument main body, a searchlight is connectedwith the upper surface of the detection and inspection instrument main body, outside of the convex mirror, through a rotating mechanism, first cavities are symmetrically arranged at the lower part inthe detection and inspection instrument main body; a telescopic mechanism is arranged in each first cavity; the longitudinal parts of T-shaped sliding rods of the telescopic mechanisms are in slidingfit with the cavities; the transverse parts of the T-shaped sliding rods are arranged outside the first cavities in parallel with the upper surface of the detection and inspection main body; the two ends of the transverse parts, away from the end surface of the detection and inspection main body, are both provided with a sliding mechanism for detecting the sliding of the detection and inspection main body. According to the invention, the instruments solves the problems of difficult operation by using a hand-held handle and a long detection and maintenance time period when a prior lower detection and inspection instrument for the high-speed railway vehicle is in use.

Description

technical field [0001] The invention relates to an instrument for inspecting the bottom of a high-speed rail, in particular to an under-vehicle detection and inspection instrument for a high-speed rail. Background technique [0002] The under-vehicle detection and inspection instrument of the high-speed rail is an instrument for checking whether the chassis of the high-speed rail is damaged or has some potential safety hazards. It is widely used in the inspection and maintenance of the chassis of the high-speed rail by staff. [0003] A commonly used simple inspection device is an inspection mirror, which consists of a convex mirror, a handle and a searchlight. The user holds the device and probes the convex mirror part into the bottom of the high-speed rail, and inspects it by reflecting the high-speed rail chassis through the glass mirror or stainless steel mirror. Obviously, due to the long high-speed rail, the narrow chassis and track of the high-speed rail, the device ...

AI Technical Summary

Problems solved by technology

[0004] Based on the above problems, the present invention provides an under-vehicle detection and inspection instrument for high-speed rail, which solves the problems that the existing under-vehicle detection and inspection instrument for high-speed rail is difficult to operate with a handle and the inspection and maintenance period is long.
