Abstract

A system and method for adjustably positioning elevator guide rail. The system includes: an adjustment device arranged on a moving platform and having a clamping portion and a powering portion, the clamping portion being arranged to be capable of clamping an elevator guide rail to be installed through a power output from the powering portion and moving in a first, a second and/or a third directions, and the moving platform being capable of moving up and down in the first direction; a detection device arranged to detect current movement characteristics of the clamping portion when the elevator guide rail is not clamped or has been clamped by the clamping portion; and a control device connected to the detection device and the adjustment device, and arranged to adjust the position of the clamping portion in place by controlling the powering portion according to the movement characteristics.

First claim

What is claimed:

1. A system for adjustably positioning elevator guide rail, comprising:
an adjustment device configured to be arranged on a moving platform and having a clamping portion and a powering portion, the clamping portion being arranged to be capable of clamping an elevator guide rail to be installed through a power output from the powering portion, the powering portion configured to move the clamping portion in a second direction and a third direction, and the moving platform being capable of moving up and down in a first direction;
a detection device arranged to detect current movement characteristics of the clamping portion when the elevator guide rail is not clamped or has been clamped by the clamping portion;
a control device connected to the detection device and the adjustment device, and arranged to adjust the position of the clamping portion in place by controlling the powering portion according to the movement characteristics so that the clamped elevator guide rail can be positioned and installed at a target position;
a support device, which is installed on the moving platform and connected to the adjustment device so that the adjustment device is arranged on the moving platform, and which is arranged to abut against at least one side of an elevator hoistway along the second direction at an installation area of the elevator guide rail;
a connection device arranged between the support device and the adjustment device to enable the adjustment device to move relative to the support device in the first direction and the third direction, wherein the adjustment device is located vertically above the support device.

2. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the support device comprises at least one bracket, and the support device is installed on the moving platform through the bracket.

3. The system for adjustably positioning elevator guide rail according to claim 2 , wherein the bracket has an assembly portion arranged to be detachably installed on the moving platform.

4. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the support device comprises:
a body;
one or more moving portions connected to the body and arranged on at least one side of the body; and
an actuation portion arranged to enable at least a part of the moving portions to move relative to the body in the second direction, so as to adjust a length of the support device in the second direction and make the support device abut against at least one side of the elevator hoistway.

5. The system for adjustably positioning elevator guide rail according to claim 4 , wherein the support device comprises two moving portions, which are symmetrically arranged on both sides of the body.

6. The system for adjustably positioning elevator guide rail according to claim 4 , wherein the actuation portion comprises a driving member installed on the moving portions to provide power to the moving portions.

7. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the support device and the adjustment device are both arranged substantially along the second direction.

8. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the adjustment device comprises a body and one or more moving portions, the moving portions are connected to the body and arranged on at least one side of the body, and the clamping portion is connected to the moving portions.

9. The system for adjustably positioning elevator guide rail according to claim 8 , wherein the adjustment device comprises two moving portions, which are symmetrically arranged on both sides of the body.

10. The system for adjustably positioning elevator guide rail according to claim 8 , wherein the powering portion comprises a first driving member installed on the moving portions to provide power to the moving portions, and a second driving member installed on the clamping portion to provide power to the clamping portion.

11. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the detection device comprises at least one position sensor, and the movement characteristics comprise positions of the clamping portion in the first direction, the second direction and/or the third direction detected by the position sensor.

12. The system for adjustably positioning elevator guide rail according to claim 11 , wherein the position sensor is arranged on the adjustment device and/or the clamped elevator guide rail, data of the positions comprises distances between the clamping portion and a reference located in an elevator hoistway in the first direction, the second direction and/or the third direction, and the control device is arranged to control the powering portion to adjust the position of the clamping portion in place by comparing the distances with corresponding distances between the detected target position and the reference in the first direction, the second direction and/or the third direction.

13. The system for adjustably positioning elevator guide rail according to claim 12 , wherein the reference comprises a reference line arranged in the elevator hoistway.

14. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the control device is connected to the detection device and/or the adjustment device in a wireless manner, and the control device comprises a mobile terminal.

15. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the system for adjustably positioning elevator guide rail further comprises a display device connected to the control device and arranged to display data related to the movement characteristics and/or provide human-computer interaction operations which comprise inputting or modifying data related to the target position.

16. The system for adjustably positioning elevator guide rail according to claim 1 , wherein the moving platform is an elevator car.

17. A method for installing and adjusting elevator guide rail, comprising the steps of:
arranging the system for adjustably positioning elevator guide rail according to claim 1 on the moving platform, and making the moving platform run to an installation area of the elevator guide rail;
using the detection device to detect current movement characteristics of the clamping portion when the elevator guide rail is not clamped or has been clamped by the clamping portion; and
adjusting the position of the clamping portion in place by controlling the powering portion of the adjustment device using the control device according to the detected movement characteristics so that the clamped elevator guide rail can be positioned and installed at a target position.

18. The method for adjustably positioning elevator guide rail according to claim 17 , further comprising the step of abutting the support device against at least one side of the elevator hoistway along the second direction at the installation area when the system for adjustably positioning elevator guide rail is provided with the support device, before using the detection device for detection.
