Problems solved by technology
However, the sample line will be removed after the guide rail installation is completed because the sample line will interfere with the elevator components installed later
Since then, the linearity of the guide rail cannot be accurately measured, and it is very difficult to analyze, adjust and check the cause of the elevator ride comfort problem caused by the poor linearity of the guide rail.

Embodiment Construction
[0017] The tooling of the present invention can re-stake out and inspect the guide rail 7 of the elevator in use, and is applicable to each stage of elevator installation, use, maintenance, and transformation. It provides accurate basis and great convenience for the cause analysis, adjustment and inspection of the elevator ride comfort problem caused by the poor linearity of the guide rail 7.
[0018] Such as figure 1 As shown, the tooling of the present invention includes an upper stakeout tooling 3, a lower sample line fixing tool 5 and a detection tooling 4; the upper stakeout tooling 3 is fixed on the top rail 7 of the shaft 6; the lower sample line fixing tool 5 is fixed on the bottom rail of the shaft 6 7; the detection tool 4 is located between the upper stakeout tool 3 and the lower sample line fixing tool 5, and is used to measure the size of the guide rail 7 in each part.
[0019] Such as figure 2 As shown, the upper lofting tool 3 is composed of a main body panel...

The invention discloses a tool for lofting and checking an available elevator guide rail and a using method thereof. The tool comprises an upper lofting tool, a lower line transect fixing tool and a detection tool, wherein the upper lofting tool is fixed on a guide rail at the top of a shaft well; the lower line transect fixing tool is fixed on aguide rail at the bottom of the shaft well; and the detection tool is positioned between the upper lofting tool and the lower line transect fixing tool and is used for measuring the sizes of the guide rail on each part. The tool is suitable for various stages of mounting, use, maintenance and transformation of an elevator, overcomes the defects that the guide rails of the available elevator are not renewedly lofted, checked and measured by using the traditional process, can be used for renewedly lofting and checking the guide rails of the available elevator, and accurately measures the linearity of the guide rails of the available elevator. The tool is easy to operate and convenient to assemble; and the reason of bad elevator riding comfort caused by the poor linearity of the guide rails is analyzed, adjusted and checked, so that an accurate evidence and the great convenience are provided.
Description
technical field [0001] The invention belongs to the field of elevator installation and maintenance, and specifically refers to a tool for performing lofting (piano wire setting) and inspection on the guide rail 7 of the elevator in use; accurately measuring the linearity of the guide rail of the elevator in use and its use method. Background technique [0002] The installation size (linearity) of the elevator guide rail directly affects the ride comfort of the elevator and the service life of elevator guide shoes and other components. In the installation stage of the elevator guide rail, the method of setting out the line (setting the piano line) will be adopted, and the linearity of the guide rail will be adjusted and checked based on the position of the sample line. This method is currently recognized as the most accurate method for setting and checking the linearity of guide rails. However, since the sample line will interfere with the elevator components installed later...
