Problems solved by technology

[0002] Usually, the door and car of the elevator are suspended in the elevator shaft by multiple ropes. If the tension of the door driving rope of the hanging door drops, failures such as the door being unable to open and close will occur.
In addition, if there is a deviation in the main ropes that hang the car, the ride experience of the elevator will deteriorate
In addition, the main rope itself or the pulleys that are wound around the main rope and driven cause friction loss, and replacement work is required for these parts.

Embodiment 1

[0025] figure 1 It is a figure which shows the outline|summary of the main rope tension measuring device of the elevator concerning Example 1 of this embodiment. This figure (a) is a perspective view, and this figure (b) is a side view of this figure (a).

[0026] The main rope tension measuring device 100 involved in this embodiment is a device for measuring the main rope tension in the main rope tension applying device 20, such as figure 1 As shown in (b), it includes a camera 11, a lower frame 9 supporting the camera 11, an upper frame 12, and a personal computer (hereinafter referred to as a personal computer) 40, and the image data of an image captured by the camera 11 is sent to the personal computer 40. , and the personal computer 40 performs predetermined processing based on the transmitted image data. The personal computer 40 performs image processing on the captured image and displays it on its own monitor, which will be described later, and also has a remote opera...

Embodiment 2

[0036] image 3 It is a figure which shows the outline|summary of the main rope tension measuring device 100 of the elevator concerning Example 2, Figure 4 is its top view. image 3 and in Example 1 figure 1(b) corresponding. Since it is the same as the first embodiment except for the mounting structure of the camera 11 , the same reference numerals are assigned to the same components, and overlapping descriptions will be omitted.

[0037] In the second embodiment, the lower bracket 9 in the first embodiment is omitted, and the upper bracket 12 is held by the rod 7, which is an example of a cantilever bracket 18 adopting a cantilever structure. One end of the cantilever bracket 18 includes a clamping portion 19 for grasping and fixing the rod 7 , and the other end side supports the camera 11 .

[0038] In addition, a scale 14 for measuring the length of the tension spring 4 is provided on the upper surface of the elevator shaft structure main body 2 in parallel with the r...

Embodiment 3

[0043] Figure 5 It is a figure which shows the schematic structure of the bracket used in the main rope tension measuring device 100 of the elevator concerning Example 3, Image 6 is to use Figure 5 The schematic diagram of the main rope tension measuring device 100 of the elevator of the frame shown.

[0044] Figure 5 (a) is a top view of the bracket, Figure 5 (b) is a sectional view showing the stent structure. Figure 5 In (a), the bracket 20 includes: two plate-shaped first and second body parts 27a, 27b; first and second magnet parts 25a, 25a, and 25b; and the connecting shaft 28 is connected to the other end side of each main body part 27a, 27b so that each main body part 27a, 27b can rotate and slide. The first and second magnet parts 25a, 25b are also attached to the respective main body parts 27a, 27b so as to be rotatable by 360 degrees via the first and second shaft members 26a, 26b.

[0045] Since the first and second body parts 27a, 27b are connected so ...

Abstract

A main rope tension measurement device and a main rope tension adjustment method may efficiently measure tension of a main rope, in which a main rope end is installed to a top part of a hoistway via a tension spring. A main rope tension measurement device for measuring tension of plural main ropes (30) in which, main rope ends (3) are installed to a top part of a hoistway (1) of an elevator via tension springs (4), as length of the tension springs, comprises: a camera (11) for imaging the tension springs (4); brackets (9, 12) for supporting the camera (11) so that the plural tension springs (4) are in a field angle, and a focus is adjusted; and a personal computer (40) for imaging the plural tension springs (4) by the camera (11) when a car (21) of the elevator is moved to an intermediate part of the hoistway (1), and acquiring the imaged images.

Description

technical field [0001] The invention relates to a main rope tension measuring device for measuring the main rope tension of an elevator and a main rope tension adjusting method using the main rope tension measuring device. Background technique [0002] Usually, the doors and the car of the elevator are suspended in the elevator shaft by a plurality of ropes. If the tension of the door driving rope of the hanging door drops, failures such as the door being unable to open and close will occur. In addition, if a deviation occurs in the main ropes suspending the car, the ride quality of the elevator will deteriorate. In addition, frictional loss occurs in the main rope itself or the pulleys that are wound around the main rope and driven, and it is necessary to replace these components. Therefore, a maintenance worker regularly goes to the site and checks the tension of the main rope and the door driving rope. [0003] As a general method of checking the tension of the rope, th...
