Hoist-transportating machine rail span, linearity automated detection method

Abstract

The invention relates to an automatic detection method for the span and straightness of a hoisting and transporting machinery track, comprising the following steps: step 1, setting a prism between the tracks as a common reference point; step 2, setting up a Total station, set up a measuring point prism on the track that can move along the track; step 3, make the measuring point prism move along the track from the head end C to the tail end E, and the total station measures and records the prism on the track trolley by tracking The three-dimensional coordinates (xa, ya, za) of the running track point of the prism; at the same time refer to the height difference hc of the public reference point record point and the total station; Step 4, erect the total station and the measuring point prism on the head end of another track B D, record the three-dimensional coordinates (xb, yb, zb) of the running track point of the prism on the track dolly; simultaneously refer to the height difference hd of the public datum point record point and the total station; step 5, calculate the straightness and levelness of the track respectively, The span and height difference of the same section of the track between the two tracks.

Description

technical field [0001] The invention relates to the automatic detection of the rails of gantry-type and bridge-type lifting and transporting machinery, in particular to a detection method for the geometric quantity of the rails. Background technique [0002] With the development of science and technology, industrial production continues to develop in the direction of continuity, scale and automation. Lifting and transporting machinery is widely used in the transportation of raw materials, semi-finished products, and finished products in industrial production, as well as the replacement and maintenance of equipment, and is an important equipment for enterprises. The gantry and bridge crane transport machinery track installed in the industrial plant or on the ground in soft ground, its foundation and surroundings are affected by static load or dynamic load, and uneven settlement or displacement is prone to occur after long-term load operation. The track will be deformed to va...

Problems solved by technology

In addition to the review of the measurement data, the inspection of the calculation results, and the review of the result report, it takes 12 people to spend nearly 8 hours to complete a 300m long track measurement work (data sampling is carried out at intervals of 3 meters)

With the deepening of safety management in enterprises, the safety management of high-altitude operations is further strengthened, requiring high-altitude workers not to be out of the effective protection of seat belts, while traditional driving track measurement is a labor-intensive high-altitude measurement work that requires a lot of investment Manpower and time, especially the span and straightness of the track, must be fastened to the safety belt during the measurement process and step over the high-altitude safety fence to measure separately, which not only disperses the workers, but also causes great hidden dangers to the safe operation of the measurement
