Embodiment approach 1

[0030] figure 1 The repairing device of the elevator of this Embodiment 1 is shown schematically. In this state, the rope is removed from the sheave 1 of the elevator. However, as will be described later, there is no problem even if there is a rope. The sheave 1 is called the driving sheave, deflector pulley or pulley of the traction machine of the elevator or the hoisting machine. As we all know, a plurality of rope grooves, that is, sheave grooves 20, are formed on the circumferential surface. The tank 20 is wound and rotated on an axis extending in a direction perpendicular to the paper surface.

[0031] The repair device for repairing the sheave groove 20 is constituted to include: a repair agent injection machine 6, which is configured to be able to inject repair agent 7 in the sheave groove 20 installed on a driving machine (not shown in the figure); a shape sensor 4, which faces The bottom 2 of the sheave groove 20 is equipped with a shape obtaining surface; a cleani...

Embodiment approach 2

[0055] In the first embodiment described above, it was assumed that the rope 11 was removed from the sheave 1 for repair, but in this embodiment, the sheave groove 20 is repaired while the rope 11 is being wound. Figure 8 Described below.

[0056] In this embodiment, the repairing device of the sheave groove 20 is arranged on the side of the sheave 1 where the rope 11 is not wound so as not to come into contact with the rope 11 . With such a configuration, even in the state where the rope 11 is wound around the sheave 1 , the sheave groove can be repaired while removing dirt or oil discharged from the rope 11 .

[0057] In the control device 8, by linking the elevator with the control mechanism of the repairing device, the time period for repairing the sheave groove can be controlled according to the operating conditions of the elevator.

[0058] That is, since the repairing agent is injected while rotating the sheave, even if the rope is wound, the sheave groove can be repa...

Embodiment approach 3

[0069] In the above-mentioned second embodiment, it is assumed that the rope 11 is wound on the sheave 1 having a drive mechanism to perform repairs, but in this embodiment, as Figure 9 shown, compared to Figure 8 In the shown embodiment 2, the above-mentioned sheave 1 is set as the driving sheave 1a, and the driven sheave 1b is added, and the driven sheave 1b with the rope 11 wound around the two sheaves 1a and 1b is Make repairs.

[0070] In this embodiment, the repairing device for the sheave groove is arranged on the side of the driven sheave 1b where the rope 11 is not wound, so that the shape sensor 4 and the injection machine 6 constituting the repairing device do not come into contact with the rope 11 . Then, the driven sheave 1b is rotated by rotating the driving sheave 1a in a state where the rope 11 is wound, so that the driven sheave 1b can be rotated to a position to be repaired.

[0071] exist Figure 9 In , it is described that the signal of the amount of r...

Abstract

Provided is an elevator repairing device that completes repair in a short period of time without repairing by way of plating, wherein a three-dimensional printer is formed from: a storage device for storing set shape data for a sheave groove; a shape sensor for measuring the shape of the sheave groove; an injection machine for projecting a repairing agent into the sheave groove; and a control device that compares the set shape data in the storage device and data measured by the shape sensor, and controls the amount of the repairing agent injected from the injection machine.

Description

technical field [0001] The invention relates to an elevator repairing device, in particular to a wear repairing device for a sheave groove of an elevator. Background technique [0002] The grooves of the sheave (hereinafter referred to as sheave grooves.) are worn due to slippage between the elevator ropes (ropes) and the sheave for raising and lowering the elevator car by means of the ropes. In this sheave, a plurality of sheave grooves are formed, and wear may concentrate on a specific sheave groove and cause a wear step difference from other sheave grooves. When this wear step occurs, the fluctuation of the tension of the rope increases, which may deviate from the tension of the rope assumed in the design. [0003] Regarding this problem, in order to eliminate the wear level difference, the recutting of the grooves has conventionally been performed on site, but the following problems have arisen in the recutting of the grooves. [0004] ·It is necessary to remove the ro...
