Problems solved by technology

However, once the main cable 2 is removed, the deflector wheel 6 cannot be refurbished due to the lack of a driving device.
Therefore, stopping the operation of the elevator for a long time to replace the deflector wheel 6 itself has become the main reason for significantly increasing the cost and reducing the quality of service
[0013] The groove shape measuring device of the prior art sheave does not take into account that the main cable 2 can be effectively refurbished without removing the main cable 2 from the drive cable pulley, and does not consider the deflector even if there is no drive device. Wheels can also be refurbished

Abstract

The invention provides a processing device for an elevator steel cable groove which can renovate and process the steel cable groove used for driving a steel cable wheel in a short time, and can prevent the service quality of the elevator from decreasing. The invention is provided with a mounting part (8) which is demountably arranged on a fixing rack (5) of the elevator, a processing part (9) which is arranged at the opposite position of the steel cable groove part of a main steel cable (2) being used for suspension hanging the case of the elevator and being positioned inside the steel cable groove (4a) of a driving steel cable wheel (4), and a movable bearing part (13) which is arranged on the mounting part and used for bearing the processing part and which can move along the rotating axle direction and the radius direction of the driving steel cable wheel. The processing part is provided with a rotary grinding wheel (10) which is used for grinding and processing the steel cable groove. The rotary axle (16) of grinding wheel forms an angle of about 30 degrees with a tangent (17) starting from the processing point of the driving steel cable wheel.

Description

technical field [0001] The present invention relates to an elevator cable groove machining device and a machining method thereof for efficiently refurbishing a cable groove formed on a driving sheave or a deflector sheave of an elevator winch. Background technique [0002] Fig. 14~17 has shown existing elevator wire groove processing device, and Fig. 14 is the general configuration diagram of elevator configuration, and Fig. 15 is the schematic configuration diagram of the driving cable pulley of elevator winch, and Fig. Figure 17 is a schematic configuration diagram showing the state in which the processing has been completed. [0003] Among Fig. 14, 1 is the suspension box of elevator, and 2 is the main steel cable of suspension suspension box 1, and one end of main steel cable is fixed on the suspension box 1. 3 is counterweight, is fixed on the other end of main steel cable 2. 4 is the driving cable wheel of the elevator winch arranged in the machine room, etc., and th...
