Hand-push type multifunction laser contact net detection instrument

Abstract

The present invention provides a hand-propelled multifunctional laser contact network detection apparatus. It is composed of car wheel, car body, pushing bar, measurement aiming head and data processor. The described measurement aiming head also includes laser distance sensor, camera head and beam splitter prism, and the data processor includes control circuit, liquid crystal display, keyboard and power supply. Besides, said invention also provides their connection mode and the working principle of said detection apparatus.

Description

technical field [0001] The invention relates to a detection device for a geometric parameter of an electrified railway catenary. Background technique [0002] At present, there are three types of detection equipment for the geometric parameters of the electrified railway catenary. 1) The contact type insulating rod is matched with a scale, and the suspension measurement method is adopted. This method is greatly affected by the environment and has poor measurement accuracy. 2) Hand-held laser catenary detector, due to the heavy weight of the instrument and the high labor intensity of the workers, optical sighting is used for aiming, which is difficult to aim, slow in measurement speed, and low in automation. 3) The catenary parameter detection vehicle is installed on a standard train body with a measuring bow. The measuring bow is in contact with the catenary line during the running of the train, and the pull-out value and guide height of the catenary are measured through the...

[0002] At present, there are three types of detection equipment for the geometric parameters of the electrified railway catenary. 1) contact-type insulating rods, with scales, adopt the suspension measurement method, which is greatly affected by the environment and has poor measurement accuracy.

2) Hand-held laser catenary detector, due to the heavy weight of the instrument and the high labor intensity of the workers, optical aiming is used for aiming, which is difficult to aim, slow in measurement speed, and low in automation

3) The catenary parameter detection vehicle is installed on a standard train body with a measuring bow. The measuring bow is in contact with the catenary line during the running of the train, and the pull-out value and guide height of the catenary are measured through the built-in displacement sensor of the measuring bow. It is suitable for It is not suitable for routine inspection and maintenance of electrified railway power supply sections and construction inspections of construction units for irregular inspections of intra-office lines
