Description

Technical Field

[0001] The utility model relates to the technical field of boom length measurement, in particular to an end mounting structure of a telescopic boom length measuring instrument. Background Art

[0002] When measuring the telescopic length of the telescopic arm of an aerial work vehicle, a length measuring instrument is often used, such as the WTC / J type length measuring angle instrument of the Weite. The measuring instrument body of the device is set on the fixed arm, such as Figure 1 , 2 As shown, a measuring line is wound around the measuring instrument body, one end of which is connected to the end of the telescopic arm. The telescopic arm drives the measuring line to move, and the extension length of the telescopic arm is determined by detecting the displacement of the measuring line. At present, the measuring line is fixed on the telescopic arm in various forms, and the fixing structure may have the risk of falling off, resulting in the need to frequently fix the measuring line again. After fixing, it is not easy to disassemble, and it is not convenient for replacement and maintenance. Summary of the invention
