Description

A trolley used for track detection of hoisting machinery

technical field

The invention relates to the detection technology of the hoisting machinery track, in particular to a trolley used for the detection of the hoisting machinery track.

Background technique

In modern industrial production, logistics and other fields, hoisting machinery is playing an increasingly important role. The normal operation of hoisting machinery is directly related to the normal production, work efficiency and benefits of the enterprise, and the society has higher and higher requirements for hoisting machinery. Most of the hoisting machinery runs on the track, and the working condition of the track directly determines the stability and safety of the hoisting machinery. Especially when the track condition is very poor, the wheel rim of the hoisting machinery touches the side of the track, and generates a horizontal lateral thrust, resulting in "rail gnawing". "Rail gnawing" will cause great damage to the wheels and tracks of the hoisting machinery, and may burn out the motor or twist the drive shaft, causing a lot of working noise and vibration. Especially serious "rail gnawing" will even damage the structure of the house, and suddenly derail in the middle of the situation, causing major safety accidents.

The requirements of the national standard for the hoisting machinery track mainly include the straightness of the single track, the span and height difference of the same section of the double track. The traditional method is mainly to use steel tape measure, spirit level and feeler gauge to complete the work, which requires many inspectors to climb up to work, the inspection intensity is high, the risk is high, and the measurement results are read out manually, the accuracy is relatively low, and the efficiency is low. . In the face of modern and increasingly large lifting machinery and equipment, traditional methods can no longer meet the inspection requirements and are gradually being eliminated.

Aiming at the current inspection status of the hoisting machinery track, some scholars at home and abroad have proposed new methods, and the trolley running on the hoisting machinery track is an important device for detecting the installation of the target reflector. The literature "Journal of Shanghai University of Science and Technology" "Development of Crane Rail Inspection Robot" and patent CN103776373A "A Crane Rail Inspection Device" each proposed a trolley running on the hoisting machinery rail, but both of them have complex structure of the trolley , unstable operation and other shortcomings.
