Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and more specifically, to a height positioning tool for rapid positioning of escalator rails. Background Technology

[0002] In the production of escalators (automatic escalators) for rail transit, the rail clamping plate (also known as the "guide rail clamping plate" or "rail clamping device") is a key component to ensure the stable operation of the escalator step chain or tread. During installation, the rail clamping plate needs to firmly press the guide rail onto the escalator's supporting structure (such as a truss) to prevent displacement of the guide rail due to long-term vibration or load impact. At the same time, it must be ensured that the straightness and parallelism of the guide rail meet the operational requirements.

[0003] With the rapid development of the manufacturing industry, higher requirements have been placed on the assembly quality of escalator guide rails, and rail clamping technology is also facing new challenges. Due to the large length and heavy weight of escalator guide rails, problems such as poor assembly accuracy are prone to occur during installation. Current rail clamping technologies to address this issue mainly include: ① using laser measurement and CNC positioning technology to ensure that the straightness and parallelism of the guide rails are controlled within ±0.5mm; ② using integrated sensors to monitor the rail clamping preload in real time to prevent over-tightening or loosening. However, the application of new technologies undoubtedly increases operating and production costs, necessitating the development of a high-precision positioning fixture for rapid positioning of escalator rail clamps. This fixture should be low-cost, have high installation accuracy, and be easy to manufacture. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a tooling for positioning the height of escalator rails. It is simple to manufacture and has high assembly accuracy. It can not only solve the problems of stress relaxation and inaccurate parallelism control in traditional bolt tightening, but also effectively reduce production costs and provide convenient and fast multi-directional positioning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tooling for positioning the height of escalator rails includes a reference positioning component, adjustable locking components, and guide stabilizing components. Two adjustable locking components are fixed to both sides of the reference positioning component, with the adjustable locking components close to both ends of the reference positioning component. Two guide stabilizing components are fixed to both ends of the reference positioning component. A level is set on the top surface of the reference positioning component. The side of the reference positioning component is provided with grid scale lines. Each adjustable locking component includes a first elastic steel sheet and a second elastic steel sheet, which are fixed to the reference positioning component at intervals.

[0007] Furthermore, the reference positioning component is made of aluminum alloy.

[0008] Furthermore, the bottom surface of the reference positioning component is provided with an anti-slip rubber pad, which is located between the bottom surface of the reference positioning component and the guide rail mounting surface.

[0009] Furthermore, the reference positioning component is precision machined using CNC machining.

[0010] Furthermore, the first elastic steel sheet and the second elastic steel sheet are respectively provided with opening slots, and the reference positioning member passes through the opening slots and is welded and fixed to the first elastic steel sheet and the second elastic steel sheet through the opening slots.

[0011] Furthermore, the first elastic steel sheet is located between the guide stabilizer and the second elastic steel sheet, and the gap between the guide stabilizer and the first elastic steel sheet is smaller than the gap between the first elastic steel sheet and the second elastic steel sheet.

[0012] Furthermore, the adjustable locking element is manufactured using a laser cutting process.

[0013] Furthermore, a limiting groove is provided in the middle of the guide stabilizer, and the reference positioning component passes through the limiting groove and is welded and fixed to the guide stabilizer through the limiting groove.

[0014] Furthermore, the guide stabilizer has reinforcing ribs on its front side, which are located on both sides of the limiting groove.

[0015] Furthermore, the guide stabilizer is made of Q235 steel plate through shearing and bending.

[0023] The tooling for positioning the height of escalator rails according to this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figure 1 This utility model discloses a tooling for positioning the height of escalator rails, including a reference positioning component 1, adjustable locking components 2, and guide stabilizing components 3. Two adjustable locking components 2 are respectively fixed to both sides of the reference positioning component 1, with the adjustable locking components 2 close to both ends of the reference positioning component 1. Two guide stabilizing components 3 are respectively fixed to both ends of the reference positioning component 1. A level 4 is disposed on the top surface of the reference positioning component 1. The level 4 is used to adjust the levelness of the guide rail during installation.

[0025] Please see Figure 2 The reference positioning component 1 is made of aluminum alloy and is precision machined using CNC (Computer Numerical Control). The side of the reference positioning component 1 features grid lines for easy and quick alignment during installation. An anti-slip rubber pad 11 is located on the bottom surface of the reference positioning component 1 between the bottom surface of the reference positioning component 1 and the guide rail mounting surface. The anti-slip rubber pad 11 enhances the friction between the bottom surface of the reference positioning component 1 and the guide rail mounting surface, preventing tooling displacement during construction. The reference positioning component 1, in conjunction with the level 4, ensures that the guide rail installation height error is ≤ ±1mm and the levelness deviation is ≤ 0.5°.

[0026] Please see Figure 1 and Figure 3 The adjustable locking element 2 is manufactured using laser cutting technology. Each adjustable locking element 2 includes a first elastic steel sheet 21 and a second elastic steel sheet 22, which are fixed to the reference positioning element 1 at intervals. The first elastic steel sheet 21 and the second elastic steel sheet 22 are each provided with an opening slot. The reference positioning element 1 passes through the opening slot and is welded and fixed to the first elastic steel sheet 21 and the second elastic steel sheet 22 through the opening slot. The first elastic steel sheet 21 is located between the guide stabilizing element 3 and the second elastic steel sheet 22, and the interval between the guide stabilizing element 3 and the first elastic steel sheet 21 is smaller than the interval between the first elastic steel sheet 21 and the second elastic steel sheet 22.

[0027] Please see Figure 1 and Figure 4The guide stabilizer 3 is made of Q235 steel plate, which is sheared and bent into one piece, resulting in a lightweight and high-strength structure. A limiting groove 31 is provided in the middle of the guide stabilizer 3, through which the reference positioning component 1 passes and is welded to the guide stabilizer 3. Reinforcing ribs 32 are provided on the front of the guide stabilizer 3, located on both sides of the limiting groove 31, effectively dispersing stress during the rail pressing process. The guide stabilizer 3 adopts a lightweight, high-strength structure, ensuring strength while reducing weight and improving construction convenience.

[0028] Using a tooling fixture to position the escalator rail height, place the reference positioning component 1 on the guide rail mounting surface. Use the anti-slip rubber pad 11 to enhance the friction between the bottom surface of the reference positioning component 1 and the guide rail mounting surface to prevent displacement. Initially calibrate the position using grid lines to ensure accurate alignment with the guide rail. Insert the guide stabilizing component 3 into the guide rail and adjust the level to ensure the guide rail is level. Insert the adjustable locking component 2 into the guide rail and adjust the locking mechanism to complete the guide rail fixing.

[0029] In summary, this utility model is a tooling for positioning the height of escalator rails. The reference positioning component 1 is precision machined by CNC, the adjustable locking component 2 is made by laser cutting, and the guide stabilizing component 3 is integrally formed by cutting and bending Q235 steel plate. It has a simple structure, is easy to disassemble and assemble, adapts to the installation requirements of guide rails of different specifications, improves installation efficiency, and enhances stability.
