Technical Field

[0001] This utility model relates to the technical field of elevator component measuring tools, specifically to a measuring tool for the plumbness of elevator components. Background Technology

[0002] When installing components such as elevator guide rails, their plumbness is measured. Currently, the traditional plumb line method is mainly used to measure plumbness. This involves attaching a magnet to one end of a plumb line on the elevator guide rail, pulling the plumb line downwards to the desired position, waiting for the plumb line to stabilize, and then using a ruler to measure the distance L1 between the plumb line and the side wall of the elevator guide rail. Finally, this method is used to measure different distances at different points along different sections, and the error between these distances is used to characterize the plumbness. This traditional method heavily relies on the operator's experience, eyesight, and control over the plumb line. Furthermore, the plumb line is easily shaken when measured with a ruler, leading to inconvenience and affecting measurement accuracy and efficiency. In addition, existing measuring tools are relatively limited in function; when measuring whether components with inclines meet the standards, additional measuring tools are required for further inspection.

[0020] This utility model provides a tool for measuring the plumbness of elevator components, referring to... Figure 1The measuring tool for the plumbness of elevator components includes a measuring ruler 1, which is made of transparent material for easy observation of the internal structure. The measuring ruler 1 includes a one-piece horizontal ruler 11 and a vertical ruler 12, which are L-shaped, facilitating the simultaneous measurement of deviations in both the horizontal and vertical directions.

[0021] Reference Figure 1 and Figure 2 A vertical ruler 12 has an I-shaped groove at its end away from the horizontal ruler 11, extending along the length of the vertical ruler 12 away from the horizontal ruler 11. An I-shaped magnetic strip 2, adapted to the groove, is inserted into the groove. The magnetic strip 2 is flush with the outer wall of the vertical ruler 12 on the side away from the horizontal ruler 11, ensuring the flatness of the vertical ruler 12. A secondary injection of adhesive is applied to the opening of the I-shaped groove along the length of the vertical ruler 12 away from the horizontal ruler 11, fixing the magnetic strip 2 to the vertical ruler 12 and preventing it from detaching from the groove. The magnetic strip 2 allows the measuring tool to be firmly attached to metal components of the elevator, such as guide rails and door frames, facilitating single-person measurement.

[0022] Reference Figure 2 and Figure 3 The spirit level 11 has a liquid cavity 14 inside, which contains a colored liquid, such as red or blue, for easy observation and identification. The liquid does not completely fill the cavity 14, leaving space for air bubbles to facilitate observation of the liquid level. Both sides of the spirit level 11 have viewing openings 13, through which the position and state of the liquid can be observed to determine the verticality of the measured component on the corresponding side.

[0023] Reference Figures 2 to 4 A baffle 32 is provided at the opening of the liquid chamber 14 to block the opening of the liquid chamber 14 and is fixedly connected to the level 11 by secondary glue injection to ensure airtightness. An adjustment assembly 3 is provided inside the liquid chamber 14 to adjust the tilt of the liquid level to adapt to different measurement scenarios. The adjustment assembly 3 includes an adjustment rocker 31, which is rotatably mounted in the middle position inside the liquid chamber 14. The adjustment rocker 31 divides the liquid chamber 14 into a first chamber and a second chamber that are not interconnected, with the liquid level located in the first chamber.

[0024] Reference Figures 2 to 5A protrusion 34 is integrally formed on the side of the baffle 32 near the second chamber, and a semi-cylindrical groove 35 is provided on the side of the protrusion 34 near the adjusting rocker 31. A rotating column 36 is fixedly provided on the side of the adjusting rocker 31 near the protrusion 34. The rotating column 36 is rotatably inserted into the semi-cylindrical groove 35 to form a rotatable connection, allowing the adjusting rocker 31 to rotate flexibly. Both ends of the adjusting rocker 31 are secondary injection molded with rubber tongues 37. The rubber tongues 37 are tightly abutted against the cavity wall of the liquid cavity 14 and are in an elastic compression state. Within the adjustment range of the adjusting rocker 31, the rubber tongues 37 are tightly abutted against the wall of the liquid cavity 14 to maintain a seal. At the same time, sealing grooves are provided on both sides of the adjusting rocker 31, and a rubber strip 38 is provided in each sealing groove. The rubber strip 38 is tightly abutted against the cavity wall of the liquid cavity 14 to form a seal, effectively preventing liquid leakage.

[0025] Reference Figures 2 to 5 Two adjusting screws 33 are threadedly installed on the baffle 32. The two adjusting screws 33 pass through the baffle 32 and are located in the second chamber, respectively abutting against the two sides of the adjusting rocker plate 31. By rotating the adjusting screws 33 with a portable Allen wrench, the tilt angle of the adjusting rocker plate 31 can be changed, thereby adjusting the reference position of the level liquid. This allows it to be used in different measurement scenarios. For example, after the reference value of the level liquid tilt is adjusted in advance, the magnetic strip 2 is attached to the part being measured. If the level liquid is horizontal, then the tilt of the corresponding part is qualified.

[0026] The fluoroscopic port 13 has scale lines 4 on both sides of the horizontal liquid where it is tilted, which are used to observe the tilt of the horizontal liquid and make the measurement results more accurate. Users can also calculate the tilt of the measured part based on the values ​​of the scale lines 4 on both sides.

[0027] The implementation principle of a measuring tool for the plumbness of elevator components according to an embodiment of this application is as follows: In use, a vertical ruler 12 is attached to the elevator component to be measured via a magnetic strip 2, and the position of the horizontal liquid is observed through the two viewing ports 13. If the horizontal liquid is not at the reference position of the scale line 4, it indicates that the component has a plumbness deviation. The scale line 4 can quantify the deviation value, facilitating recording and adjustment. The reference position of the horizontal liquid can be adjusted by the adjusting component 3 to adapt to different measurement requirements. Thus, the technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model; for those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
