Abstract
Description
Technical Field
[0001] This utility model belongs to the field of elevator testing equipment technology, and in particular relates to an intelligent laser testing ruler for the verticality of elevator guide rails that can be tested in segments. Background Technology
[0002] In the field of elevator installation and maintenance, guide rail verticality is a core indicator for ensuring the safety and stability of elevator operation. Excessive deviation in guide rail verticality can lead to car sluggishness, abnormal noises, and even structural wear, and in severe cases, may cause safety accidents. Therefore, extremely high requirements are placed on the accuracy and efficiency of its detection.
[0003] In traditional inspection methods, when a deviation in the perpendicularity of the guide rail is detected, manual marking is often used, such as marking the guide rail surface with chalk or markers. This method has significant drawbacks: firstly, manual marking relies on the experience and judgment of the inspectors, which can easily lead to deviations between the marked position and the actual deviation point due to subjective errors, and it is difficult to quantify the deviation angle; secondly, the environment inside the elevator shaft is complex, dimly lit, and confined, making manual marking inconvenient and inefficient. Furthermore, the markings are easily blurred by dust and moisture, causing significant problems for subsequent calibration work.
[0004] While some existing automated testing equipment can detect verticality deviations in real time, there are still functional deficiencies or incompleteness in the deviation marking process. Most devices can only display the deviation value through data display and lack a synchronous marking mechanism. Testing personnel must return to the deviation location to mark it after recording the data, increasing repetitive work. The few devices that do have marking functions mostly use single-color scratches or marks, which cannot distinguish between different degrees of offset angles, making it difficult for calibration personnel to quickly identify the deviation level and affecting adjustment efficiency.
[0005] To address the aforementioned issues and achieve integrated and intelligent detection and marking, it is essential to integrate precise and efficient spray marking functions into verticality detection equipment. By linking with the detection system, the corresponding type of marking powder can be automatically sprayed when a deviation is detected, clearly indicating the location and angle level of the deviation, thus providing an intuitive and reliable basis for subsequent calibration work.

This facilitates quick location and maintenance adjustments by subsequent personnel, improving work efficiency. This device can adapt to the detection needs of elevator guide rails of different specifications, possessing strong practicality and versatility. Attached Figure Description

[0035] Reference Figures 1-5 A segmented intelligent laser measuring ruler for the verticality of elevator guide rail 1 includes:
[0036] Cover plate 2 is used to be installed at one end of elevator guide rail 1;
[0037] Movable seat 4, a movable plate 21 is slidably disposed on one side of the movable seat 4, a laser offset detection device is disposed on one side of the movable plate 21, and a driving device 37 is disposed on one side of the movable seat 4 for driving the movement of the movable plate 21.
[0038] The side wall of the movable seat 4 is symmetrically equipped with connecting plates 38, and the connecting plates 38 are rotatably equipped with spraying components 26 for spraying the verticality offset position of the elevator guide rail 1.
[0039] When the movable plate 21 moves, it drives the connecting plate 38 to rotate.
[0040] This device is positioned and installed at one end of the elevator guide rail 1 via the cover plate 2; the movable plate 21 on the movable seat 4 can drive the laser offset detection device to move, and the detection position can be adjusted in conjunction with the drive device 37; in conjunction with the spraying component 26, the verticality of the elevator guide rail 1 can be detected in segments and the offset position can be accurately marked, providing an integrated solution for the verticality detection and correction of the elevator guide rail 1.
[0041] As a preferred example of this application, the driving device 37 includes a baffle 24 and a second motor 17. The second motor 17 is mounted on the movable seat 4. The baffle 24 is mounted on one side of the movable plate 21. A first rack 19 is provided on one side of the movable plate 21. A first gear 18 is connected to the driving end of the second motor 17.

The second gear 30 is mounted on one end of the spraying assembly 26.
[0042] The second motor 17 drives the movable plate 21 to move smoothly through the meshing of the first gear 18 and the first rack 19, thereby realizing the position adjustment of the laser offset detection device.
[0043] As a preferred example of this application, the spraying assembly 26 includes a spraying tank body 8, an inner cylinder 27, and a rotating shaft 28. The spraying tank body 8 has an internal cavity. The rotating shaft 28 is rotatably disposed in the cavity, and one end of the rotating shaft 28 movably passes through the spraying tank body 8 and is fixedly connected to a disc 29. The disc 29 is fixedly connected to a second gear 30. The inner cylinder 27 is disposed in the cavity. The top of the rotating shaft 28 is fixedly connected to the inner cylinder 27. A plurality of powder storage tanks 31 are disposed inside the inner cylinder 27. A plurality of connecting holes 34 are disposed on the inner cylinder 27. The connecting holes 34 are connected to the corresponding powder storage tanks 31. A spray nozzle 36 is disposed on the top of the spraying tank body 8. The spray nozzle 36 is connected to the corresponding connecting hole 34 through a micro spraying pump. The spraying tank body 8 is fixed on a connecting plate 38.
[0044] It should be noted that the micro spraying pump needs to be used in conjunction with a laser offset detection device and equipped with a control processor. The laser offset detection device sends the detection signal to the control processor, and the control processor controls the micro spraying pump to spray markings. The signal processing and transmission is a well-known technology and will not be described in detail here.
[0045] The rotating shaft 28 drives the built-in cylinder 27 to rotate, which can switch the correspondence between different powder storage tanks 31 and the connection hole 34; the powder in the corresponding powder storage tank 31 is sprayed out through the nozzle 36 by the spray pump to mark the offset position; the spray tank body 8 is fixed to the connecting plate 38 to ensure that the spraying component 26 moves synchronously with the connecting plate 38, and to ensure that the marked position is consistent with the detected offset position.
[0046] The built-in cylinder 27 is provided with a plurality of powder storage tanks 31, and the powder storage tanks 31 contain powders of different colors.
[0047] By using powders of different colors, it is possible to visually distinguish different degrees of vertical deviation of the elevator guide rail 1 (such as slight deviation, moderate deviation, severe deviation, etc.), which makes it easier for subsequent maintenance personnel to quickly identify the degree of deviation and improve maintenance efficiency.
[0048] As a preferred example of this application, the surface of the inner cylinder 27 is fitted with a rubber elastic retaining pin 32, and the inner wall of the spray can body 8 is provided with a groove 33, and the elastic retaining pin 32 fits into the groove 33.
[0049] When switching the state of the powder storage tank 31, the elastic retaining pin 32 is engaged in the groove 33 to fix the position of the inner cylinder 27, preventing it from rotating unexpectedly due to vibration or other factors, ensuring the precise correspondence between the powder storage tank 31 and the connection hole 34, and ensuring the accuracy of the spray marking.
[0050] As a preferred example of this application, a clamping assembly is symmetrically installed on one side of the movable seat 4. The clamping assembly is used to slide the movable seat 4 onto the elevator guide rail 1. The clamping assembly includes a clamping groove 5 formed on the movable seat 4. A clamping plate 6 is provided in the clamping groove 5. The clamping plate 6 is slidably connected to the clamping groove 5 through a limiting rod. A spring 7 is spirally provided on the limiting rod. The two ends of the spring 7 are respectively connected to the inner wall of the clamping groove 5 and the clamping plate 6.
[0051] Spring 7 pushes clamping plate 6 with elastic force, so that clamping plate 6 fits tightly against elevator guide rail 1, and the movable seat 4 is stably clamped on elevator guide rail 1; the limiting rod restricts the movement direction of clamping plate 6 to ensure clamping stability; at the same time, the elasticity of spring 7 can adapt to different specifications of elevator guide rail 1 within a certain range, thus improving the versatility of the lifting device.
[0052] As a preferred example of this application, the clamping plate 6 is rotatably provided with a guide wheel 9 on the side near the elevator guide rail 1, and the guide wheel 9 is in contact with the elevator guide rail 1 under the elastic force of the spring 7.
[0053] Under the action of spring 7, guide wheel 9 is in contact with elevator guide rail 1, which converts the sliding friction of movable seat 4 when it moves along elevator guide rail 1 into rolling friction, reduces the moving resistance, and makes the movable seat 4 move more smoothly; at the same time, guide wheel 9 plays a guiding role, ensuring that movable seat 4 moves in a straight line along elevator guide rail 1, and improving the positional accuracy of segment detection.
[0054] As a preferred example of this application, the laser offset detection device includes a transmitter 3 and a plurality of receivers. The transmitter 3 of the laser offset detection device is fixedly disposed on one side of the cover plate 2. The laser offset detection device is provided with a plurality of receivers, including a left receiver 14, a middle receiver 15, and a right receiver 16. In the initial state, the middle receiver 15 corresponds to the laser emitted by the transmitter 3. The receivers are fixedly disposed on the mounting box 13, and the mounting box 13 is fixed on the movable seat 4.
[0055] The laser emitted by transmitter 3 is initially aligned with receiver 15, indicating that the verticality of elevator guide rail 1 is normal. When elevator guide rail 1 deviates, the laser will be directed to left receiver 14 or right receiver 16. By observing the position of the receiver receiving the signal, the direction and approximate amount of deviation of elevator guide rail 1 can be determined, thus realizing the segmented detection and judgment of the verticality of elevator guide rail 1.
[0056] As a preferred example of this application, a first motor 11 is installed on the side wall of the movable seat 4, and the drive shaft of the first motor 11 is connected to a drive wheel 10, which is in contact with the elevator guide rail 1.
[0057] The first motor 11 drives the drive wheel 10 to rotate. The drive wheel 10 comes into contact with the elevator guide rail 1 and generates friction, which drives the movable seat 4 to move automatically along the elevator guide rail 1 without manual pushing. This achieves automated segmented detection of the verticality of the elevator guide rail 1, improving detection efficiency and consistency of the detection process.
[0058] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
