A self-alignment laser device for a jack

Abstract

The invention discloses a self-straightening alignment laser device for a jack. The self-straightening alignment laser device comprises a diode laser pen and a clamping mechanism which is used for clamping the diode laser pen, wherein the clamping mechanism is connected with a converting seat through a double-shaft transposition mechanism; the bottom of the clamping mechanism is also connected with a spherical structure which can enables the clamping mechanism always be vertical to the horizontal surface in the double-shaft transposition mechanism; the self-straightening alignment laser device is mounted at the top of the jack through the converting seat; the spherical structure at the bottom of the diode laser pen clamping mechanism can be used for making the clamping mechanism rotate freely so that the light of the diode laser pen can be kept to be vertical to the horizontal surface all the time, and thus the accuracy of location and alignment is guaranteed; the self-straightening alignment laser device is mounted on the head of the jack so that light spots which are formed when an airplane is irradiated by the light of the laser pen are transferred to the inside of a jacking recess of the airplane, i.e., the head of the jack is in plumb bob alignment to the jacking recess of the airplane, thus the problem that a human-eye collimation alignment method wastes time and labor and is unsafe is solved, the jacking time is saved, and the safety in jacking is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aircraft weighing, and relates to an aircraft ground jacking jack, an aircraft weighing system and a center of gravity testing system, in particular to a self-aligning laser device for jacks. Background technique [0002] Accurate, fast, safe, stable and smooth use of jacks to jack up the aircraft is very important in the ground support of the aircraft. Similarly, the combination of jacks and sensors to accurately measure the weight and center of gravity of the aircraft is essential to ensure the safe flight of the aircraft. necessary. [0003] During the process of lifting the aircraft with a jack, or combining the jack with the sensor to weigh the aircraft, due to the large size and heavy weight of the aircraft jack, it is very difficult to move and align the jacks on the aircraft, especially the head of the jack. Or when the head of the sensor installed on the top of the jack is in alignment with the ...
