Description

Technical Field

[0002] In recent years, with the high-quality development of high-end equipment manufacturing industry, the automation and intelligence of cranes have become increasingly higher, and the requirements for the structural accuracy of cranes, especially the track accuracy that has an important impact on the running accuracy of large and small vehicles, have become more stringent; GB / T10183.1-2018 and ISO12488-1:2012 and other standards clearly stipulate that when the crane trolley and trolley tracks use flat-top tracks, they are divided into different tolerance levels (1, 2, 3, and 4) according to the total mileage of the entire life cycle of the lifting equipment. The deflection of the top surface of the track needs to be controlled within different quality requirements such as 4‰, 6‰, 9‰, and 12‰. If the quality control requirements are not met during production or installation, the running accuracy and running stability of the crane operating mechanism will be seriously affected during use, and the service life of the equipment will be reduced;

[0003] Currently, the commonly used detection tool is the bubble level, which only needs to be placed on the plane to be detected to observe the bubble offset and read the scale to measure the inclination; however, the existing track body is generally I-shaped, and the top surface is not a complete plane, but chamfers are provided on both sides of the top, which results in a narrow width of the flat top surface, which is not conducive to the placement of a bubble level with higher accuracy and longer length. In addition, if the artificially placed bubble level is not perpendicular to the track, it will also affect the measurement accuracy. Utility Model Content

If there are many track specifications for detection and the width difference is not too large, then the spacing between the two vertical plate portions 102 can be slightly greater than the widest track width. The plate surface of one of the vertical plate portions 102 is provided with a threaded hole adapted to be threaded with a positioning screw 5. The height of the threaded hole needs to be such that when the flat plate portion 101 contacts the top surface of the track, the positioning screw 5 can be screwed to contact the web of the I-shaped track; as needed, the inner and outer ends of the positioning screw 5 are respectively installed with a top plate and a screwing handle 6, the screwing handle 6 is convenient for manual screwing, and the top plate can increase the contact area of ​​the positioning screw 5 to ensure stable and accurate contact positioning;
