Description

Technical Field

[0001] The invention relates to the technical field of equipment detection, and in particular to a device for measuring the verticality of an elevator guide rail. Background Art

[0002] The elevator guide rail is a device used to limit the elevator car to ensure that the elevator car can remain stable during travel. In order to ensure the stability of the elevator car during travel, the verticality of the elevator guide rail needs to be detected. The traditional elevator guide rail verticality measuring device uses the principle of vertical downward gravity and the effect of light emission in a straight line to measure, thereby obtaining data on the verticality of the guide rail. However, the existing mainstream elevator guide rails include T-type guide rails and groove-type guide rails, and the traditional measuring device has certain inconveniences in adaptation. In addition, during the measurement process, the measuring device needs to move along the extension direction of the elevator guide rail. The vibration generated during the process will also affect the measurement accuracy, resulting in errors in the measurement results. In this regard, the present application document proposes a device for measuring the verticality of an elevator guide rail, aiming to solve the above-mentioned problems. Summary of the invention

[0007] Specifically, the outer surfaces of the two groups of connected truncated tables are movably mounted with a front swing device and a rear swing device, respectively. When the rotating device as a whole rotates along the axis of the rotating shaft, the front swing device and the rear swing device will swing simultaneously with the rotating device as a whole.

[0008] Specifically, a limit spring is fixedly installed on one side of the top of the connecting frame, and the limit spring connects the two rotating devices.

[0009] Furthermore, when the device measures the T-shaped guide rail, a shorter limit spring is used. At this time, the limit spring is in a stretched state.

[0035] See also Figure 3-Figure 5 A limit spring 10 is fixedly installed on one side of the top of the connecting frame 412, and the limit spring 10 connects the two rotating devices 4.

[0036] See also Figure 3-Figure 5 When the device measures the T-type guide rail, a shorter rotating device 4 is used. At this time, the rotating device 4 is in a stretched state. The guide wheel 411 is pulled inward by the limit spring 10, thereby clamping the protruding part of the T-type guide rail. When the device measures the grooved guide rail, a longer rotating device 4 is used. At this time, the rotating device 4 is in a compressed state. The guide wheel 411 is pushed outward by the limit spring 10, thereby contacting the side wall of the grooved guide rail. The device can be used in T-type elevator guide rails and grooved elevator guide rails. When the verticality of the T-type elevator guide rail needs to be measured, When measuring, a shorter limit spring 10 is used. At this time, the limit spring 10 is in a stretched state. Through the pulling of the limit spring 10, the guide wheel 411 approaches the inside, thereby clamping the protruding part of the T-shaped guide rail. When it is necessary to measure the verticality of the groove-type elevator guide rail, a longer limit spring 10 is used. At this time, the limit spring 10 is in a compressed state. Through the pushing of the limit spring 10, the guide wheel 411 approaches the outside, thereby contacting the side wall of the groove-type guide rail, thereby achieving adaptation to two different types of elevator guide rails, thereby improving the scope of application and practicality of the device.

[0037] See also Figure 4-Figure 7 The front swing device 7a includes a swing long rod 71, which is sleeved on the outer side of the connecting truncated table 410. A connecting bracket 72 is fixedly installed on one end of the swing long rod 71. The front and rear sides of the inner wall of the connecting bracket 72 are provided with sliding grooves 73. The sliding grooves 73 cooperate with the recording device 8. The tail end of the swing long rod 71 contacts the arc-shaped limiting plate 6, thereby limiting the swing long rod 71.

[0038] See also Figure 6-Figure 7 The structure of the rear swing device 7b is the same as that of the front swing device 7a, and the front swing device 7a and the rear swing device 7b are at different heights, and the connecting bracket 72 in the front swing device 7a and the connecting bracket 72 in the rear swing device 7b correspond to each other in the vertical direction.

[0039] See also Figure 3 and Figure 6-Figure 9 The recording device 8 includes a sliding sleeve 81. Upper protrusions 82a and lower protrusions 82b are respectively arranged on both sides of the outer surface of the sliding sleeve 81 near the bottom and the middle. The number of the upper protrusions 82a and the lower protrusions 82b are two respectively. The upper protrusion 82a cooperates with the connecting bracket 72 in the front swing device 7a, and the lower protrusion 82b cooperates with the connecting bracket 72 in the rear swing device 7b. A supporting spring 83 is fixedly installed at the bottom of the inner cavity of the sliding sleeve 81. A recording pen 84 is arranged on the internal movable sleeve of the sliding sleeve 81. The bottom of the recording pen 84 is connected to the supporting spring 83, and the top of the recording pen 84 is in contact with the winding device 9. Under the action of the elastic force of the supporting spring 83, the top of the recording pen 84 is always in contact with the winding device 9.

[0040] See also Figure 1-Figure 11The winding device 9 includes a mounting plate 91, and a power roller 92 is fixedly installed at the bottom of the mounting plate 91 near the two ends. The outer surface of the power roller 92 is sleeved with a recording paper 93. A pad 94 is fixedly installed at the middle position of the bottom of the mounting plate 91. The recording paper 93 is in contact with the pad 94, and the top of the recording pen 84 is in contact with the recording paper 93. When the front swing device 7a and the rear swing device 7b swing under the drive of the rotating device 4, the recording device 8 will be driven to swing as a whole, so that the recording pen 84 leaves a mark on the surface of the recording paper 93. In the process of measuring the elevator guide rail, the bottom of the support seat 5 is in contact with the bottom of the elevator guide rail. When it is pulled by manual pulling or traction equipment, the device can move along the extension direction of the elevator guide rail. In this process, when the elevator guide rail is bent or offset, which affects the verticality, it will cause the elevator guide rail and the guide wheel to be in contact with each other during the passing of the rotating device 4. The force at the contact position 411 increases, thereby pushing the guide wheel 411, causing the rotating device 4 to rotate as a whole along the axis of the rotating shaft 41, thereby driving the swing long rod 71 to rotate synchronously. In this process, the upper protrusion 82a cooperates with the connecting bracket 72 in the front swing device 7a, and the lower protrusion 82b cooperates with the connecting bracket 72 in the rear swing device 7b, so that the connecting bracket 72 drives the recording pen 84 to swing and leave a mark on the surface of the recording paper 93. The greater the degree of bending or displacement of the elevator guide rail, the greater the amplitude of the overall rotation of the rotating device 4, and the greater the length of the mark left by the recording pen 84 on the surface of the recording paper 93. The user can judge the position and degree of bending or displacement of the elevator guide rail through the mark position and mark length on the surface of the recording paper 93, and determine whether the elevator guide rail is qualified. The entire use process is simpler and the operation is more convenient, which further improves the practicality of the device.

[0041] Since the device is provided with rotating devices 4 on both sides of the strip hole 2, when the device detects the elevator guide rail and passes through a bent or offset position, the front rotating device 4 will first swing in the forward direction, and when the rear rotating device 4 passes again, the rear rotating device 4 will swing in the reverse direction again. The two rotating devices 4 swing twice in different directions, which will cause the recording pen 84 to leave two different marks of equal length and symmetrical to each other on the surface of the recording paper 93. When the user checks the surface of the recording paper 93, the irregular and asymmetrical marks left on the surface of the recording paper 93 by the vibration of the device can be effectively eliminated through this rule, thereby avoiding measurement errors caused by vibration and improving the measurement accuracy of the device.

[0042] Due to the elastic force of the limit spring 10 itself, the stability of the structure of the rotating device 4 can be effectively maintained by pulling or pushing the connecting frame 412, thereby preventing the rotating long arm Ⅰ43a and the rotating long arm Ⅱ43b from rotating when the rotating device 4 passes through the bending or offset part of the guide rail, thereby reducing the overall rotation amplitude of the rotating device 4, causing the recording pen 84 to be unable to leave marks on the surface of the recording paper 93 normally, thereby improving the stability of the device during operation.

[0043] The method of use of the present invention is as follows:

[0044] Before use, first determine the type of elevator guide rail to be tested. If it is a T-type elevator guide rail, use a shorter limit spring 10. At this time, the limit spring 10 is in a stretched state. Through the pulling of the limit spring 10, the guide wheel 411 moves closer to the inside, thereby clamping the protruding part of the T-type guide rail. If it is a groove-type elevator guide rail, use a longer limit spring 10. At this time, the limit spring 10 is in a compressed state. Through the pushing of the limit spring 10, the guide wheel 411 moves closer to the outside, thereby contacting the side wall of the groove-type guide rail. At the same time, the bottom of the support seat 5 contacts the bottom of the elevator guide rail, thereby completing the assembly of the device and the elevator guide rail.

[0045] During use, first start the power roller 92 to drive the recording paper 93 to move, confirm that the recording pen 84 can leave a clear mark on the surface of the recording paper 93, and then drive the device to move at a uniform speed along the extension direction of the elevator guide rail by manual pulling or pulling with a traction device. When the elevator guide rail is bent or offset, which affects the verticality, the force at the contact position between the elevator guide rail and the guide wheel 411 will increase during the passage of the rotating device 4, thereby pushing the guide wheel 411, causing the rotating device 4 to rotate along the axis of the rotating shaft 41 as a whole, thereby driving the swinging long rod 71 to rotate synchronously. During this process, the connecting bracket 72 drives the recording pen 84 to swing and leave a mark on the surface of the recording paper 93. The greater the degree of bending or offset of the elevator guide rail, the greater the amplitude of the overall rotation of the rotating device 4, and the greater the length of the mark left by the recording pen 84 on the surface of the recording paper 93. The user can judge whether the elevator guide rail is out of order by the mark position and mark length on the surface of the recording paper 93. The position and degree of bending or deviation are determined to determine whether the elevator guide rail is qualified. When passing through the bending or deviation position, the front rotating device 4 will first swing in the forward direction. When the rear rotating device 4 passes again, the rear rotating device 4 will swing in the reverse direction again. The two rotating devices 4 swing twice in different directions, which will cause the recording pen 84 to leave two different marks of equal length and symmetrical to each other on the surface of the recording paper 93. When the user checks the surface of the recording paper 93, the regularity can be used to effectively eliminate the irregular and asymmetrical marks left on the surface of the recording paper 93 due to vibration of the device. The elastic force of the limit spring 10 itself will pull or push the connecting frame 412, which can effectively maintain the stability of the structure of the rotating device 4, and eliminate the problem that when the rotating device 4 passes through the bending or deviation of the guide rail, the rotating long arm Ⅰ43a and the rotating long arm Ⅱ43b rotate, thereby reducing the overall rotation amplitude of the rotating device 4, causing the recording pen 84 to fail to leave marks on the surface of the recording paper 93 normally.
