A crane track measuring device

Abstract

The invention discloses a crane railway measuring device which comprises a trolley used for walking on a railway, a laser receiving screen, a video device, an on-trolley controller, a distance measuring device and a power supply, wherein the laser receiving screen, the video device, the trolley controller, the distance measuring device and the power supply are fixed on the trolley. The laser receiving screen is a semi-transparent screen and is erected on a base plate, and the video device is located behind the back portion of the laser receiving screen and faces toward the laser receiving screen. According to the crane railway measuring device, light-spot coordinates corresponding to different distance locations of the railway are recorded, change of height deviation and horizontal deviation of different locations of the railway, span and high-low difference of a left railway and a right railway and other parameters can be detected, a curve graph is drawn, and therefore the detection goal is achieved. Due to the fact that the whole detection process can be remotely controlled in a wireless mode, detection and measurement can be conveniently achieved on a crane elevated railway.

Description

technical field [0001] The invention belongs to the technical field of special equipment detection, and relates to the detection of crane rail installation tolerance and related parameter changes during use, especially the measurement of the height deviation and horizontal deviation of the crane rail, and the measurement of the span difference and height difference between left and right rails. Background technique [0002] As a special equipment, cranes have strict requirements on installation tolerance and track position tolerance in the standard "GB / T10183-2005". This requires detection of crane rail installation tolerances and changes in related parameters during use, especially the height deviation, level deviation, and span and height differences of the left and right rails. However, the rails of cranes are often installed at high altitudes. In the past, it was very difficult to inspect the rails erected in the high altitudes. It was difficult to set up inspection equi...

AI Technical Summary

Problems solved by technology

However, the rails of cranes are often set up at high altitudes. In the past, it was very difficult to detect the rails erected in the high altitudes. It was difficult to set up inspection equipment, the labor intensity was high, the inspection efficiency was relatively low, and there was a danger of the inspection personnel falling.
