Description

Technical Field

[0001] This invention relates to the field of elevators, and more specifically to a multi-station elevator installation and testing mold. Background Technology

[0002] During the installation, commissioning, and acceptance of an elevator, it is necessary to measure the relative dimensions between many components to ensure the elevator's safe and stable operation. Examples include the distance between the landing sill and the car door sill; the distance between the car door blade and the landing sill; and the gap between the landing door and the door frame.

[0003] During the measurement process, difficulties in reading values ​​may arise due to limitations imposed by the measurement angle, surrounding environment, and component shape. This results in low installation efficiency and a cumbersome measurement process.

[0004] For example, under current conditions, measuring the gap between the landing door sill and the car door sill, and the gap between the landing door sill and the door knife, typically uses a 150mm steel ruler. However, due to limitations in the observation angle, insufficient ambient light, and the curvature of the measuring surface, readings are inconvenient and inefficient. When measuring the gap between the landing door and the door frame, a beveled feeler gauge is usually used. Similarly, the inconvenient observation angle also leads to inaccurate readings, and the friction between the metal beveled feeler gauge and the landing door surface easily causes scratches, affecting the protection of the finished product.

[0005] In addition to the above-mentioned problems, existing conventional measuring tools cannot be effectively positioned on relevant structural parts in the measurement of door knife spacing; multiple people need to work together to operate the measuring tools, provide lighting, and take readings, which leads to poor consistency of human judgment in multiple measurement results.

[0006] Meanwhile, in the measurement of the distance between floor sills, in addition to the above-mentioned problems, existing conventional measuring instruments are suspended due to the height difference between the sills, which affects the accuracy of the readings; the curvature of the edge of the sill structure affects the fit and positioning of the measuring instruments; and it is difficult and time-consuming to align the measurement and read the data. Summary of the Invention

[0007] The technical problem to be solved by this invention is how to provide a measurement tool that is easy to use in elevator installation, commissioning, and acceptance processes, applicable to multiple scenarios, and aimed at improving efficiency while ensuring measurement accuracy.

[0048] like Figures 1-2 As shown, the present invention provides an elevator multi-station installation and testing mold, comprising:

[0049] At least one detection reference plane;

[0050] The step surface that is parallel to the detection reference surface;

[0051] The elevator multi-station installation and testing mold is used to measure the gap distance between two objects being tested. The testing reference surface and the step surface are respectively abutted against the measured surfaces of the two objects being tested during measurement.

[0052] like Figures 1-5 As shown, the detection reference surface includes a first detection reference surface 1; the step surface includes a first step surface; the body of the elevator multi-station installation detection mold is a T-shaped plate; the first detection reference surface 1 is located at the lower edge of the T-shaped head; there are two sets of first step surfaces, namely the first set 4 and the second set 5, symmetrically distributed on both sides of the upper edge of the T-shaped head of the body. The first set 4 and the second set 5 are formed on multiple steps on both sides of the top, and the height of each step on both sides is uniform but not the same. The elevator multi-station installation detection mold is used to measure the gap distance between the landing sill 12 and the car door sill 11. During measurement, the first detection reference surface 1 and the first step surface are respectively in contact with the measured surfaces of the landing sill 12 and the car door sill 11.

[0053] like Figure 2 , Figure 6 , Figure 7 As shown, the detection reference surface of the present invention may further include a second detection reference surface 2 and a third detection reference surface 8; the step surface includes a second step surface 6; the second detection reference surface 2 is a protrusion provided on the vertical part of the T-shape; the third detection reference surface 8 is provided on the vertical part of the T-shape and is perpendicular to the second detection reference surface 2; the second step surface is symmetrically distributed at the end of the vertical part of the T-shape, and the step height on both sides is uniform.

[0054] The elevator multi-station installation and testing mold is used to measure the gap distance between the landing sill 12 and the car door knife 13. The second testing reference surface 2 and the second step surface 6 are respectively in contact with the measured surfaces of the landing sill 12 and the car door knife 13 during measurement; the third testing reference surface 8 is in contact with the upper surface of the landing sill 12 during measurement.

[0055] like Figure 8 , Figure 9 As shown, the detection reference surface of the present invention may further include a fourth detection reference surface 3; the stepped surface includes a third stepped surface 7; the fourth detection reference surface is disposed on the front side of the body of the elevator multi-station installation detection mold; there are two sets of the third stepped surface, distributed on both sides of the T-shaped head on the back of the body, and the step height on each side is uniform. The elevator multi-station installation detection mold is used to measure the gap distance between the landing door 14 and the door frame 15. The fourth detection reference surface 3 and the third stepped surface 7 are respectively in contact with the measured surfaces of the landing door 14 and the door frame 15 during measurement.

[0056] Preferably, the highest step in the third step surface 7 is set on the same horizontal plane as the third detection reference surface 8.

[0057] Preferably, the material of this invention is PLA (polylactide), which is 3D printed. With the popularization of 3D printing technology, its unique characteristics of high printing precision and environmental friendliness make it applicable in elevator installation, commissioning, and acceptance processes. Conventional PAL materials can be used to manufacture measuring tools that do not require high pressure. It also provides some protection for the exterior finish of elevator products.

[0058] The measurement steps using the elevator multi-station installation and testing mold of the present invention are as follows:

[0059] 1. Steps for measuring the gap between the landing sill and the car door sill:

[0060] When using it, place the first detection reference surface 1 of the measuring tool firmly against the car door sill 11, such as... Figure 3 As shown;

[0061] While ensuring that the first detection reference surface 1 is in close contact with the car door sill 11, the stepped measuring surface 4 is slowly brought into contact with the landing sill 12 from top to bottom. Figure 4 As shown, the gap between the landing sill 12 and the car door sill 11 can be quickly obtained.

[0062] According to industry consensus, the dimension range of the first step surface, group 4, is 30mm to 35mm, meaning each step difference is 1mm. The clearance standards between the landing sill 12 and the car door sill 11 vary among different elevator brands. The measurement range of the second step surface, group 5, can be customized to quickly check whether the standard requirements are met. For example... Figure 5 As shown.

[0063] 2. Steps for measuring the gap between the landing sill 12 and the car door knife 13:

[0064] In use, place the third detection reference surface 8 flat on the surface of the landing sill 12, and move the measuring tool towards the waiting hall so that the second detection reference surface 2 is in close contact with the other side of the landing sill. For example... Figure 6 As shown;

[0065] Move the measuring tool left and right until the measuring surface 6 contacts the door knife 13 of the car door. Figure 7 As shown;

[0066] According to industry consensus, the gap between the landing sill 12 and the car door blade 13 should not be less than 5 mm, and is usually between 7 mm and 9 mm. Therefore, the step-shaped dimension range of the second step surface 6 is selected to be between 7 and 9 mm, which allows for quick measurement of whether the door blade dimension is qualified. At the same time, the step range can be defined according to different standards to meet various acceptance requirements.

[0067] 3. Steps for measuring the gap between the landing door and the door frame:

[0068] In use, place the fourth detection reference surface 3 flat on the surface of the door 14 and slide it towards the gap in the door frame 15 so that the measuring surface 7 is inserted into the gap. Figure 8 As shown.

[0069] When the measuring surface 7 rests against the door frame 15, the stepped scale indicates the gap between the door 14 and the door frame 15. Figure 9 As shown.

[0070] Compared with existing technologies, this invention proposes for the first time a measuring tool applicable to various elevator installation and maintenance scenarios, including measuring the gap between the landing sill and car door sill, the gap between the landing sill and car door blade, and the gap between the landing door and door frame. The measuring tool utilizes 3D printing technology and can be customized to the required dimensions according to the different requirements of various elevators to meet the needs of on-site measurements during installation and maintenance.
