Abstract

The invention provides a traction wheel with the displacement deviation capable of being reduced. The traction wheel comprises a wheel body, a wiring device and a laser pen. The wiring device is tangent to wheel body. The laser pen is simultaneously tangent to the wiring device and the wheel body and is fixedly provided with a mini level. The wiring device comprises a housing, a chassis, a lockingblock, a winding drum and a toothed disc. The chassis and the locking block are fixedly arranged on the traction wheel. The winding drum is used for winding a lead wire. The toothed disc sleeves thewinding drum. The toothed disc and the drum are coaxial and rotate synchronously. The locking block comprises a knob and a limiting part. The knob is provided with a positioning rod and a locking partpenetrating through the positioning rod. The locking part is provided with a toothed part which meshes with the toothed disc. When the knob is rotated to enable the toothed disc to mesh with the locking part, the locking part is stopped by the limiting part, a guide wheel is precisely positioned, the displacement deviation of the traction wheel is reduced, positions can be simply determined, operation is facilitated, and less equipment is used.

Description

technical field

[0001] The invention relates to the field of traction elevators, in particular to a traction sheave that reduces the displacement deviation of the traction sheave. Background technique

[0002] When the traction sheave is installed, the installation displacement needs to be corrected. The correcting steps are: fix a horizontal iron wire above the traction machine, hang two vertical lines from this horizontal iron wire to align with the car frame on the wooden floor Then calculate the pitch circle diameter of the traction sheave according to the center of the traction rope, then hang another plumb line at the corresponding position on the horizontal iron wire, and finally use these standard lines to install the guide wheel Correcting the position, the steps are relatively complicated, and two people are required to coordinate the positioning of the standard line, and in the process of using the vertical line, the horizontal iron wire is easy to shift due to th...
