Description

Technical Field

[0001] The invention relates to the field of vertical elevators, in particular to an elevator guide rail precision calibration device. Background Art

[0002] During the installation of an elevator, the installation of the elevator guide rail is an important part of the elevator installation, and its installation quality directly affects the safety of the elevator operation. During the installation and calibration of the elevator guide rail, the elevator guide rail needs to be fixed vertically along the elevator shaft, and the other guide rails installed based on the bottom guide rail must be in the same straight line as the bottom guide rail to ensure that there is no shaking or abnormal noise during the operation of the elevator. The existing elevator guide rail installation and calibration methods are mostly to calibrate the installed multi-section guide rails through the vertical line calibration method, or to use laser calibration equipment, such as a high-efficiency elevator guide rail installation precision calibration equipment in application number CN202210526001.4.

[0003] Hollow rails are a type of guide rail commonly used in elevators. Standard hollow rails are transported from the manufacturer to the installation site. During the transportation process, it is possible that the guide surface of the hollow rail may be deformed inwards, which is not easy to detect. That is, the flatness of the guide surface of the hollow rail changes. At present, the functions of vertical line calibration equipment or laser calibration equipment are relatively simple. They cannot overcome the problem of flatness detection of the guide surface of hollow rails and cannot confirm whether every position on the guide surface meets the flatness requirements. It is easy for installers to use guide rails with flatness defects as standard guide rails. Once the elevator is assembled and found to be unstable, it is very cumbersome to replace the guide rails.

[0004] Therefore, it is necessary to check the flatness of the guide rail surface during the early guide rail installation and calibration process. Summary of the invention

[0026] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

The upper clamping block 1 21 and the upper clamping block 22 are both rotatably connected with a transverse roller 25 and a longitudinal roller 26. The second fastening member 23 is used to limit the transverse roller 25 and the longitudinal roller 26 to fit on the guide rail; the driving assembly 24 is used to drive the upper clamping block 1 21 and the upper clamping block 22 to slide on the guide rail;

[0030] The lower clamp block 12 and the lower clamp block 1 are respectively fixed with a level meter 31 and a laser emitter 32. After the first fastening member 13 locks and fixes the lower clamp block 11 and the lower clamp block 12 on the two guide rail surfaces of the guide rail, the installer can use the level meter 31 to detect whether the surface of the lower clamp block 11 is horizontal; the upper clamp block 21 is fixedly connected with a display board 27 with a scale corresponding to the laser emitter 32;

[0031] Different from the prior art, in this embodiment, the upper clamp block 1 21 and the upper clamp block 2 22 are provided with a second laser emitter 33 and a third laser emitter 34 respectively irradiating the two guide rail surfaces of the guide rail, the second laser emitter 33 and the third laser emitter 34 are respectively fixed at the bottom of the upper clamp block 1 21 and the upper clamp block 2 22, and obliquely emit linear laser light to the guide rail surface, and the upper clamp block 1 21 is fixedly connected with a second display board 35 and a third display board 36 respectively corresponding to the second laser emitter 33 and the third laser emitter 34;

[0032] It also includes a light reflection component 1 37, which is used to reflect the light irradiated by the laser emitter 2 33 to the corresponding guide rail surface and reflected to the display board 2 35; specifically, the light reflection component 1 37 includes a reflector 1 371 and a reflector 2 372 arranged below the upper clamping block 1 21, and a mounting frame 1 for mounting the reflector 1 371 and the reflector 2 372 is arranged at the bottom of the upper clamping block 1 21, and the reflector 1 371 reflects the light to the reflector 2 372, and the reflector 2 372 reflects the light to the display board 2 35;

[0033] It also includes a light reflection component 2 38, which is used to reflect the light irradiated by the laser emitter 3 34 to the corresponding guide rail surface and reflected to the display board 3 36; specifically, the light reflection component 2 38 includes a reflector 3 381, a reflector 4 382 and a reflector 5 383 arranged below the upper clamp block 22, and a mounting frame 2 for mounting the reflector 3 381, the reflector 4 382 and the reflector 5 383 is arranged at the bottom of the upper clamp block 22, the reflector 3 381 is used to reflect the light reflected from the guide rail surface so that the light is longitudinally emitted along the longitudinal direction parallel to the longitudinal roller 26, the reflector 4 382 is used to reflect the longitudinally emitted light so that the light is laterally emitted to the other side of the guide rail, and the reflector 5 383 is used to reflect the laterally emitted light so that the light is emitted to the display board 3 36;

[0034] When in use: fit the lower clamp block 11 and the lower clamp block 2 12 in the right angles on both sides of the guide rail respectively, and lock and fix the lower clamp block 11 and the lower clamp block 2 12 close to each other on the two guide rail surfaces through the first fastening member 13. At this time, use the level meter 31 to detect whether the surface where the lower clamp block 11 is located is horizontal. When the plane where the lower clamp block 11 is located is a non-horizontal plane, it means that this section of the guide rail is in a non-vertical state. This section of the guide rail can be adjusted to a vertical state according to the level meter 31 and fixed in the elevator shaft. Then place the upper clamp block 1 21 and the upper clamp block 22 on both sides of the guide rail, and the upper clamp block 1 21 is located above the lower clamp block 11, and the upper clamp block 22 is located above the lower clamp block 2 12. During the placement process, the laser emitter 1 32 can be started to emit laser light to illuminate the display board 1 27, wherein the display board 1 27 is a circular translucent white plastic plate with multiple rings and direction scales. Place the upper clamp block 1 21 and the upper clamp block 22 on the After the two sides of the guide rail are in contact, the longitudinal roller 72 and the drive shaft 73 rotatably connected to the second angle iron 7 can be respectively fitted with the surface of the guide rail, and compared with the scale on the display plate 27, when the laser is irradiated at the center point of the scale, the upper clamp block 1 21 and the upper clamp block 22 are mutually limited and locked through the second fastening component 23. At this time, the transverse roller 71 and the longitudinal roller 72 are both in contact with the surface of the guide rail, and then the upper clamp block 1 21 and the upper clamp block 22 are driven by the driving component 24 to slide upward along the surface of the guide rail.

[0035] During the sliding process, the position of the laser display point on the display board 1 27 within the scale can be monitored to determine whether other guide rails installed based on this guide rail have problems such as tilting or misalignment, and the upper clamp block 1 21 and the upper clamp block 2 22 can be stopped at any position of the guide rail, so that the staff can calibrate and adjust the guide rail according to the laser display point on the display board 1 27; at the same time, during the sliding process, it can also be observed whether the laser display lines of the display board 2 35 and the display board 3 36 are straight lines to determine whether there is a problem with the flatness of the guide rail surface. When the flatness of the guide rail surface is standard, the laser display lines on the display board 2 35 and the display board 3 36 are straight lines. This calibration device not only calibrates the installation accuracy of the hollow rail, but also takes into account the detection of the flatness of the guide rail surface. The detection is completed by the installation workers, and there is no need to configure special personnel and special detection equipment, and the installation cost of the guide rail is controllable.
