JPH0769562A - Aligning device for balance weight guide rail - Google Patents

Abstract

PURPOSE:To provide an aligning device for a balance weight guide rail, capable of shortening an installation prohibiting zone generated when a car frame and a balance weight pass each other. CONSTITUTION:Position restriction members 11a and 11b coupled respectively to balance weight guide rails 6 are laid at both sides of the travel locus of a balance weight 5. In addition, arms 12 are provided for fastening the members 11a and 11b to a car frame 2. According to this construction, a pitch between the support fixtures of the balance weight guide rails 6 can be made uniform, thereby enabling an alignment work to be undertaken with high accuracy.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centering device for a guide rail for a counterweight, which drives a car frame with a position regulating member attached to the guide rail for a counterweight to perform centering of the guide rail for the counterweight. Regarding

[0002]

2. Description of the Related Art FIG. 3 is a plan view showing a conventional centering device for counterweight guide rails.

Generally, in an elevator, a car frame 2 that moves up and down in the hoistway 1, a car frame guide rail 3 that guides the car frame 2, and a support metal fitting that fixes the car frame guide rail 3 to the hoistway wall 1a. 4, a counterweight 5 suspended from the car frame 2 in a slipping manner through a rope (not shown), a counterweight guide rail 6 for guiding the counterweight 5, and a counterweight guide rail 6 for the hoistway wall. A support metal fitting 7 fixed to 1a is provided.

The centering device 8 for centering the above-mentioned counterweight guide rails 6 has separable position regulating members 8a and 8b which engage with the pair of counterweight guide rails 6, respectively. There is.

Conventionally, a car frame guide rail 3 and a counterweight guide rail 6 are temporarily installed in the hoistway 1, and a car frame 2 and a counterweight 5 are installed first.
After the car frame 2 and the counterweight 5 are driven, the car frame guide rail 3 is centered, and then the counterweight guide rail 6 is centered. That is, after the position regulating bodies 8a and 8b are attached to the counterweight guide rail 6 to make them correlate with each other, the centering device 8 is aligned with the marking line 2a marked on the car frame 2, and the car frame is in this state. 2 is driven to center the counterweight guide rail 6.

[0006]

By the way, in the above-mentioned conventional centering device for the counterweight guide rail for counterweight, since this centering device interferes with the movement trajectory of the counterweight, each of them is suspended in a sliding manner. I had to remove it when the hanging basket frame and the counterweight passed each other in the middle of the hoistway. For this reason, the centering device cannot be mounted over a relatively long section of the total length of the counterweight, so that the pitch between the support metal fittings of the guide rail for the counterweight becomes unbalanced and the centering with high accuracy is performed. There was a problem that it was difficult to put out.

The present invention has been made in view of the above problems, and an object thereof is to center a guide rail for a counterweight that can shorten an unmountable section that occurs when the car frame and the counterweight pass each other. To provide a device.

[0008]

In order to achieve the above object, the present invention has a position regulating body which engages with a pair of guide rails for a counterweight of an elevator, and the counterweight is driven by driving a car frame. In a centering device for a counterweight for a counterweight for centering a guide rail, the position regulating bodies are arranged on both sides of the moving path of the counterweight, and the position regulating body is fixed to the car frame. It is configured to have members.

[0009]

Since the present invention is configured as described above, the position regulating members which engage with the guide rails for the counterweight are arranged on both sides of the moving path of the counterweight and are fixed to the car frame by the arm members. Has been done. As a result, when the car frame is driven to center the counterweight guide rails, the position regulating body does not interfere with the moving path of the counterweight, so when the counterweight and the car frame pass each other. The unmountable section of the centering device that occurs,
Only the guide shoe portions provided on the upper and lower portions of the counterweight can be used. Therefore, the non-mountable section can be shortened as compared with the conventional case in which the entire length of the counterweight is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a centering device for a counterweight guide rail according to the present invention will be described below with reference to the drawings. Figure 1
1 is a perspective view showing an embodiment of a centering device for a counterweight guide rail of the present invention, and FIG. 2 is a plan view of the centering device of FIG. The same components as those shown in FIG. 3 described above are designated by the same reference numerals. That is, 1 is the hoistway,
2 is a car frame, 3 is a car frame guide rail, 5 is a counterweight, and 6 is a counterweight guide rail.

In general, an elevator is, as shown in FIG.
Guide shoes 5a and 5b are provided on the upper and lower parts of the counterweight 5 so as to slide on the counterweight guide rails 6.

The centering device 10 of this embodiment is shown in FIG.
As also shown in FIG. 3, disengageable position regulating bodies 11a and 11b that engage with the counterweight guide rail 6 are arranged on both sides of the moving path of the counterweight 5, and the position regulating bodies 11a and 11b are arranged in the car. An arm member 12 fixed to the frame 2 is provided. The arm member 12 is slidable in the depth direction of the hoistway 1.

In this embodiment, the position regulating body 11
When engaging a and 11b with the counterweight guide rail 6, the arm member 12 is slid in the depth direction of the hoistway 1 with the dividable position restricting body 11a removed, and the counterweight guide rail 6 of the counterweight 6 is removed. The position restricting body 11b is opposed to the top surface and one side surface, then the position restricting body 11a is attached, and the position restricting body 11a is opposed to the other side surface of the counterweight guide rail 6. In this state, the car frame 2 is driven to center the counterweight guide rail 6. And
When the counterweight 5 and the car frame 2 pass each other, the guide shoes 5a, 5b interfere with the position regulating bodies 11a, 11b. The car frame 2 is driven, and then the position regulating bodies 11a and 11b are engaged again with the counterweight guide rail 6 to continue the centering.

In the embodiment thus constructed, the unmountable section of the centering device 10 which occurs when the counterweight 5 and the car frame 2 pass each other is provided with guide shoes 5a provided on the upper and lower parts of the counterweight 5, respectively. Only the portion 5b can be provided, and therefore, the unmountable section can be shortened as compared with the conventional case in which the balance weight 5 extends over the entire length.

[0015]

Since the present invention is configured as described above, it is possible to shorten the unmountable section of the centering device which occurs when the car frame and the counterweight pass each other, thereby making it possible to reduce the counterweight guide rail. The pitch between the support metal fittings can be made uniform, and therefore, there is an effect that centering can be performed with high accuracy.
