Description

An elevator wrapping belt testing device Technical Field

[0001] This utility model belongs to the technical field of elevator testing equipment, specifically relating to an elevator covering belt testing device. Background Technology

[0002] As a new type of transmission medium, elevator-coated steel belts are gradually replacing traditional steel wire ropes in elevator lifting systems, offering advantages such as low noise, light weight, long lifespan, and constant tension. However, in actual operation, the coated belts are susceptible to problems such as wear of the pulley system, abnormal tension, and localized bending, leading to defects such as surface damage, coating peeling, broken wires, and cracks, which in turn affect the stability and safety of elevator operation.

[0003] Therefore, it is necessary to design a testing device for the performance of the coating tape. Summary of the Invention

[0004] The purpose of this invention is to provide an elevator wrapping belt testing device for testing the performance of elevator wrapping belts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] An elevator wrapping belt testing device includes a frame, and a drive module, a support module, and a tensioning module that are detachably mounted on the frame.

[0007] The drive module is fixedly connected to the frame by bolts and is used to drive the elevator wrapping belt to move; the support module is arranged on the running path of the wrapping belt and is used to guide and support the running of the wrapping belt; the tensioning module is installed at the end of the running path of the wrapping belt and is used to adjust the tension of the wrapping belt.

[0008] In this application, by modularizing the functional components, the installation position and quantity of each module can be adjusted according to specific test requirements and the specifications of the wrapping tape to meet different test requirements. This approach is convenient to assemble, highly efficient, and versatile. The device boasts advantages such as compact structure, modular functionality, stable operation, and compatibility with multiple specifications of wrapping tape. It can be widely used for defect identification, operational status simulation, and life testing of elevator wrapping tapes, meeting the needs for dynamic detection, tension adjustment, and defect identification of wrapping tapes.

[0009] In a further optimization, the drive module is detachably connected to the frame via a mounting base. The drive module includes a drive wheel, a drive shaft, a coupling, and a drive motor. The drive motor is fixed on the mounting base, and the output shaft of the drive motor is connected to the drive shaft via a coupling. The drive wheel is fixedly sleeved on the drive shaft.

[0010] In a further optimization, the end of the drive shaft that is close to the coupling and not covered by the drive wheel is fitted with a drive shaft bearing. The outer ring of the drive shaft bearing is fixedly connected to the mounting bracket. The mounting bracket is detachably connected to the platform. Bearing baffles are provided at both ends of the drive shaft bearing.

[0011] Further optimization involves the support module comprising multiple roller assemblies evenly distributed along the length of the platform.

[0012] Each roller assembly includes a roller, a support shaft, a support shaft bearing, and a support shaft mounting base; one end of the support shaft mounting base is detachably connected to the frame, and the other end of the support shaft mounting base is fixedly connected to the support shaft, with the roller rotatably connected to the support shaft via the support shaft bearing.

[0013] The end of the support shaft is provided with a support shaft retaining ring, and the end of the support shaft near the support shaft mounting seat is fitted with a support shaft sleeve. The support roller is located between the support shaft retaining ring and the support shaft sleeve.

[0014] The support module guides and supports the wrapping belt, preventing it from bouncing or shifting.

[0018] By designing a linear slide, the tensioning wheel can be moved back and forth to adjust the tension of the covering belt, thus enabling the testing of the covering belt's performance under different tensions.

[0019] Further optimization involves a steel rectangular structure with multiple standardized screw holes for assembling drive and support modules, as well as guide rail interfaces for installing tensioning modules.

[0020] This test bench boasts high rigidity and excellent modular compatibility, serving as a standardized testing platform that supports various testing modules and additional components. With multiple installation stations, corresponding functional modules can be assembled according to specific needs, making it highly practical.

[0021] Further optimization involves using a servo motor as the drive motor, which allows for speed adjustment and setting of operating modes via a host computer to adapt to various test conditions.

[0022] Further optimization involves providing connectors or mounting holes on the platform for mounting an industrial camera, a tension sensor detection module, and an image processing system module.

[0023] In addition, the test bench can be expanded with the following functional modules: 1. Equipped with a high-speed industrial camera and image processing system for online identification and recording of defects such as cracks, delamination, and scratches during the operation of the covering tape. 2. Configured with a tension sensor and load module to achieve dynamic feedback of tension force and support closed-loop control algorithm testing. 3. Interface with an elevator drive simulation system or digital twin platform to achieve multi-scenario working condition simulation.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation

[0032] The specific embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] As shown in Figures 1-4, an elevator wrapping belt testing device includes a stand 100, and a drive module 200, a support module 300, and a tensioning module 400 that are detachably mounted on the stand 100.

[0034] In this embodiment, as shown in FIG2, the drive module 200 is mounted on one end of the stand and includes a drive motor 109, a coupling 107, a drive shaft 103, a drive shaft bearing 104, a drive shaft retaining ring 102, and a drive wheel 101. The drive motor is in servo control mode, and its output shaft is connected to the drive shaft 103 through the coupling.

[0035] The drive motor 109 is fixed on the mounting base 108, and the output shaft of the drive motor 109 is connected to the drive shaft 103 through a coupling. The drive wheel 101 is fixedly sleeved on the drive shaft 103.

[0036] The end of the drive shaft 103 is provided with a drive shaft retaining ring 102. A drive shaft bearing 104 is fitted onto the end near the coupling and not covered by the drive wheel 101. The outer ring of the drive shaft bearing 104 is fixedly connected to the mounting bracket 105. The entire drive module 200 is fixed to the frame 100 via the mounting bracket 105 and the mounting base 108. The drive shaft bearing 104 is fixed inside the bearing baffle 106. The drive shaft bearing 104 serves as a limiting support to prevent radial and axial sway. The drive shaft drives the drive wheel to rotate, thereby pulling the covering belt along a set path.

[0037] The stand adopts a rectangular steel structure and is equipped with multiple sets of universal holes and grooves to support modules of different specifications and adjust their installation positions.

[0038] The covering belt enters the support module area from the drive wheel. The support module 300 includes multiple roller assemblies evenly distributed along the length of the platform 100. As shown in Figure 3, each roller assembly includes a roller 1, a support shaft 2, a support shaft bearing 4, and a support shaft mounting seat 6. One end of the support shaft mounting seat 6 is detachably connected to the platform, and the other end of the support shaft mounting seat 6 is fixedly connected to the support shaft 2. The roller 1 is rotatably connected to the support shaft 2 through the support shaft bearing 4.

[0039] A support shaft retaining ring 3 is provided at the end of the support shaft 2, and a support shaft sleeve 5 is fitted onto the end of the support shaft 2 near the support shaft mounting seat 6 for limiting its position. The support roller 1 is located between the support shaft retaining ring 3 and the support shaft sleeve 5.

[0040] Each set of roller assemblies is mounted on the support shaft mounting base 6, allowing for adjustment of the lateral distribution and roller angle according to the width and curvature of the wrapping tape, thus achieving precise guidance of the wrapping tape's running trajectory. Multiple rollers are evenly distributed along the running direction, forming a flexible guide rail channel to ensure that the wrapping tape stably conforms to the running surface and prevents it from jumping or deviating.

[0041] As shown in Figure 4, the tensioning module 400 is located at the end of the wrapping belt path. The tensioning module includes a supporting linear slide 201, a tensioning wheel mounting seat 202, a tensioning wheel 203, and a tensioning wheel support shaft 205.

[0042] The linear slide 201 is detachably connected to the frame. The slider of the linear slide 201 is fixedly connected to the tension wheel mounting seat 202. The tension wheel support shaft 205 is fixedly connected to the tension wheel mounting seat 202. The tension wheel 203 is rotatably connected to the tension wheel support shaft 205 through the tension wheel bearing 204. A tension wheel support shaft retaining ring 206 is provided at the end of the tension wheel support shaft 205. A tension wheel sleeve 207 is sleeved on one end of the tension wheel support shaft 205 near the tension wheel mounting seat 202. The tension wheel 203 is located between the tension wheel support shaft retaining ring 206 and the tension wheel sleeve 207.

[0043] The linear slide is electrically or manually driven for displacement adjustment. By changing the front and rear positions of the tensioning wheel, the tension of the covering belt can be set and fine-tuned. A controllable tension section is formed between the tensioning wheel and the drive wheel to meet the simulation requirements of the covering belt's operating tension under different working conditions. Lateral movement of the tensioning wheel 203 is prevented by setting the tensioning wheel bearing 204, the tensioning wheel support shaft retaining ring 206, and the tensioning wheel sleeve 207.

[0044] In actual use, operators can adjust the position of the support rollers and the stroke of the tensioning slide according to the type of covering tape, so that the device can be matched with covering tape of different sizes.

[0045] In other embodiments, the test bench can be further equipped with other functional modules, such as a high-speed industrial camera and image processing system, for online identification and recording of defects such as cracks, delamination, and scratches during the operation of the covering tape. A tension sensor and load module are configured to provide dynamic feedback on tension force and support closed-loop control algorithm testing. This enables dynamic operation testing, allowing the covering tape to run continuously in the drive-support-tension-identification process, achieving complete defect capture and performance testing. Furthermore, it can interface with an elevator drive simulation system or a digital twin platform to achieve multi-scenario working condition simulation.

[0046] This device is particularly suitable for elevator manufacturers to conduct comprehensive performance testing on their wrapped belt products before they leave the factory. It is also suitable for research institutions to conduct material fatigue analysis and tension control algorithm development. It has the advantages of flexible structure, high detection accuracy, and expandable functions.

[0047] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
