Description

Technical Field

[0001] The invention relates to the field of vertical elevators, in particular to a device for detecting the verticality of an elevator guide rail. Background Art

[0002] During elevator installation, the installation of elevator guide rails is an important part of elevator installation. Elevator guide rails are symmetrically installed on both sides of the car or counterweight, and their installation quality directly affects the safety of elevator operation.

[0003] During the installation process, calibration can ensure that the other guide rails installed based on the bottom guide rail are in the same vertical line as the bottom guide rail, that is, the verticality is consistent, ensuring that no large shaking or abnormal noise will occur during the operation of the elevator.

[0004] The method of installing and calibrating elevator guide rails is mostly to use two suspended plumb bobs to calibrate the guide rails on both sides of the car or the counterweight by different installers. The detection speed is fast, but the plumb line connected to the plumb bob is easily affected by the wind force in the hoistway, resulting in low detection efficiency. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an elevator guide rail verticality detection device, which can be used by different inspection personnel to simultaneously inspect the guide rails on both sides of the car or both sides of the counterweight, and is less affected by wind and has higher detection efficiency.

[0006] An elevator guide rail verticality detection device comprises a detection mechanism 1 for detecting a guide rail 1 and a detection mechanism 2 for detecting a guide rail 2;

[0007] The detection mechanism 1 includes a lower clamping platform 1 and an upper clamping platform 1. The lower clamping platform 1 is provided with a level, a laser emitter 1 and a laser reflector 2. The lasers emitted by the laser emitter 1 and the laser reflector 2 are perpendicular to each other and are located in the same vertical plane. The upper clamping platform 1 is provided with a display board 1 with a scale corresponding to the laser emitter 1.

[0008] The second detection mechanism comprises a second lower clamping platform and a second upper clamping platform. The second lower clamping platform is provided with a reflector for reflecting the laser emitted by the second laser reflector vertically. The second upper clamping platform is provided with a display board with scales corresponding to the second laser reflector.

[0009] Preferably, the display board 1 is arranged on the upper surface of the upper clamping platform 1, and a through light hole 1 is arranged on the upper clamping platform 1 at a position corresponding to the display board 1; the display board 2 is arranged on the upper surface of the upper clamping platform 2, and a through light hole 2 is arranged on the upper clamping platform 2 at a position corresponding to the display board 2.

[0010] Preferably, the lower clamping table 1, the upper clamping table 1, the lower clamping table 2, and the upper clamping table 2 each include two clamping blocks and guide rods. The two clamping blocks are slidably mounted on the guide rods, and a locking structure for connecting the two clamping blocks is further included.

[0011] Preferably, the locking structure is a bolt fastener.

[0012] Preferably, a mirror frame 1 is connected below the upper clamping table 1. A beam splitter 1 is arranged on the mirror frame 1. The beam splitter 1 divides the light emitted by the laser emitter 1 into a vertical refracted light beam directed towards the exposure plate 1 and a horizontal reflected light beam directed towards the upper clamping table 2.

[0013] An exposure plate frame 1 is connected below the upper clamping table 2. A graduated exposure plate 3 facing the beam splitter 1 is arranged on the exposure plate frame 1.

[0014] Preferably, a mirror frame 2 is connected below the upper clamping table 2. A beam splitter 2 is arranged on the mirror frame 2. The beam splitter 2 divides the laser light reflected by the mirror 1 into a vertical refracted light beam directed towards the exposure plate 2 and a horizontal reflected light beam directed towards the upper clamping table 1.

[0015] An exposure plate frame 2 is connected to the clamping table 1. A graduated exposure plate 4 facing the beam splitter 2 is arranged on the exposure plate frame 2.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1: In the present invention, different inspectors can simultaneously inspect the guide rails on both sides of the car or the counterweight. The influence of wind on the inspection is small, and the inspection efficiency is higher.

[0018] 2: When the guide rails on both sides of the car or the counterweight are measured by different installers, when an installer judges the verticality of his own guide rail, he can also judge the verticality of the guide rail measured by the other party, preventing misjudgment by himself or the other party, that is, preventing misjudgment of the verticality of the guide rail, and improving the calibration quality.

[0020] Figure 2 is a schematic diagram of the structures of the lower clamping table 1, the upper clamping table 1, the lower clamping table 2, and the upper clamping table 2.

[0021] Figure 3 is a schematic diagram of the use of the second verticality detection device. DETAILED DESCRIPTION OF THE INVENTION

[0022] The present invention will be further described below with reference to the accompanying drawings through specific embodiments.

[0023] Embodiment 1: As Figure 1 shown, an elevator guide rail verticality detection device is used to detect the guide rail 01 and the guide rail 02 distributed on both sides of the car or the counterweight. It includes a detection mechanism 1 for detecting the guide rail 01 and a detection mechanism 2 for detecting the guide rail 02.

[0024] The detection mechanism 1 includes a lower clamping table 11 and an upper clamping table 12. A level 13, a laser emitter 14 and a laser reflector 2 are provided on the lower clamping table 11. The laser emission direction of the laser emitter 14 is vertical. The laser emitter 14 and the laser reflector 2 are located in the same vertical plane and the laser emission directions are perpendicular to each other, so that the lasers emitted by the laser emitter 14 and the laser reflector 2 are perpendicular to each other and located in the same vertical plane. An illuminated scale plate 16 corresponding to the laser emitter 14 is provided on the upper clamping table 12;

[0025] The detection mechanism 2 includes a lower clamping table 21 and an upper clamping table 22. A reflecting mirror 23 for reflecting the laser emitted by the laser reflector 2 into a vertical direction and a level 20 are provided on the lower clamping table 21. An illuminated scale plate 24 corresponding to the laser reflector 2 is provided on the upper clamping table 22.

[0026] During use, the lower clamping table 11 is clamped and fixed on the two guide rail surfaces of the lowermost guide rail 01, and at the same time, the level 13 is used to ensure that the lower clamping table 11 is horizontal. Similarly, the lower clamping table 21 is clamped and fixed on the two guide rail surfaces of the lowermost guide rail 02, and the level 20 is used to ensure that the lower clamping table 21 is horizontal; the upper clamping table 12 is clamped and fixed on the to-be-determined guide rail 01 above the lowermost guide rail 01, and the upper clamping table 22 is clamped and fixed on the to-be-determined guide rail 02 above the lowermost guide rail 02; the laser emitter 14 and the laser reflector 2 are turned on. The vertical laser emitted by the laser emitter 14 irradiates the illuminated scale plate 16, and the horizontal laser emitted by the laser reflector 2 is reflected vertically by the reflecting mirror 23 and then irradiates the illuminated scale plate 24. The installer determines whether the guide rails on both sides of the car or the counterweight meet the verticality requirements by observing the imaging conditions of the illuminated scale plate 16 and the illuminated scale plate 24. Only when the lasers meet the position requirements on both the illuminated scale plate 16 and the illuminated scale plate 24 does it mean that the guide rails on both sides of the car or the counterweight meet the installation requirements.

[0027] This verticality detection device can be used by different inspectors to detect the guide rails on both sides of the car or the counterweight at the same time. Moreover, the verticality detection device is less affected by the wind force in the hoistway and has higher detection efficiency.

[0028] As Figure 2As described above, the structures of the lower clamping table 11, the upper clamping table 12, the lower clamping table 21, and the upper clamping table 22 are the same, and each includes two clamping blocks 11-1 and a guide rod 11-2. The two clamping blocks 11-1 are slidably mounted on the guide rod 11-2, and further includes a locking structure 11-3 connecting the two clamping blocks 11-1. The locking structure 11-3 can specifically be a bolt fastener.

[0029] For the convenience of observing the development situation, preferably, as Figure 1 shown, the developing plate 16 is disposed on the upper surface of the upper clamping table 12, and a through light-transmitting hole 121 is provided at a position corresponding to the developing plate 16 on the upper clamping table 12; the developing plate 24 is disposed on the upper surface of the upper clamping table 22, and a through light-transmitting hole 221 is provided at a position corresponding to the developing plate 24 on the upper clamping table 22.

[0030] As Figure 3 shown, preferably, a mirror frame 17 is connected below the upper clamping table 12, and a beam splitter 18 is provided on the mirror frame 17. The beam splitter 18 divides the light emitted by the laser emitter 14 into a vertical refracted light beam directed at the developing plate 16 and a horizontal reflected light beam directed at the upper clamping table 22; a developing plate frame 25 is connected below the upper clamping table 22, and a calibrated developing plate 26 facing the beam splitter 18 is provided on the developing plate frame 25.

[0031] Meanwhile, a mirror frame 27 is connected below the upper clamping table 22, and a beam splitter 28 is provided on the mirror frame 27. The beam splitter 28 divides the laser reflected by the first mirror 23 into a vertical refracted light beam directed at the developing plate 24 and a horizontal reflected light beam directed at the upper clamping table 12; a developing plate frame 19 is connected to the clamping table 12, and a calibrated developing plate 10 facing the beam splitter 28 is provided on the developing plate frame 19. The developing plate frame 25 allows the laser reflected by the beam splitter 28 to pass through. For this reason, the developing plate frame 25 is provided with a light passing hole, which is not shown in the drawings.

[0032] The advantage of this is that when the guide rails on both sides of the car or the counterweight are measured by different installers, when the installer judges the verticality of his own guide rail, he can also judge the verticality of the guide rail measured by the other party, preventing misjudgment by himself or the other party, that is, preventing misjudgment of the verticality of the guide rail, and improving the calibration quality.

[0033] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope of the present invention. The technical content for which the present invention requests protection has been fully recorded in the claims.
