Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a spring performance testing device. Background Technology
[0002] Elevators, as indispensable vertical transportation tools in modern buildings, are of paramount importance for safety. The brake spring, as the core component of the elevator brake, plays a crucial role in providing braking force and ensuring reliable braking. In actual operation, elevator brake springs face complex and variable working environments. Different temperatures, humidity levels, and dust concentrations significantly affect the spring's material properties. For example, high temperatures reduce the spring's elastic modulus, weakening its elastic force; high humidity can cause spring corrosion, shortening its lifespan; and the presence of dust can interfere with the spring's normal expansion and contraction, affecting braking effectiveness.
[0003] Currently, most existing brake spring performance testing devices on the market can only conduct tests under a single ambient temperature and pressure environment, which cannot realistically simulate the complex operating conditions of elevators in actual operation. This makes it difficult for the test results to comprehensively and accurately reflect the performance of brake springs in actual use, and thus cannot provide reliable data support for the safe operation of elevators.
[0004] Therefore, designing a testing device and its components for testing the performance of elevator brake springs that can simulate various working conditions is of great practical significance and market demand. Utility Model Content
[0005] The main purpose of this invention is to provide a spring performance testing device, which aims to solve the problem that existing spring performance testing devices cannot test the performance of springs under actual complex working conditions.
[0006] To achieve the above objectives, this utility model proposes a spring performance testing device for testing the elastic modulus of springs under different working conditions, comprising:
[0007] Testing room;
[0008] The operating condition adjustment mechanism includes a temperature adjustment mechanism, a humidity adjustment mechanism, and a dust concentration adjustment mechanism, wherein the temperature adjustment mechanism, humidity adjustment mechanism, and dust concentration adjustment mechanism may be selectively located in the detection chamber;
[0009] A spring testing machine, at least partially located within the testing chamber, is used to measure the elastic modulus of a spring; and,
[0010] A control device is electrically connected to the spring testing machine and the working condition adjustment mechanism, and is used to control the start and stop of the spring testing machine and the working condition adjustment mechanism, and to acquire the operating data of the spring testing machine and the working condition adjustment mechanism.
[0011] In one embodiment, the spring performance testing device further includes a testing mechanism, which includes a temperature sensor, a humidity sensor, and a dust concentration sensor. The temperature sensor, humidity sensor, and dust concentration sensor are selectively located in the testing chamber corresponding to the working condition adjustment mechanism.
[0012] In one embodiment, the temperature regulating mechanism includes:
[0013] A heater is used to increase the temperature inside the detection chamber; and / or,

[0015] In one embodiment, the humidity control mechanism includes a humidifier for controlling the humidity in the detection room.
[0016] In one embodiment, the detection chamber is equipped with a humidity control mechanism;
[0017] The spring performance testing device also includes:
[0018] A water storage tank is located below the testing chamber; and,
[0019] A drain pipe connects the water storage tank and the testing chamber, and is used to guide the water in the testing chamber to the water storage tank.
[0020] In one embodiment, the dust concentration regulating mechanism includes:
[0021] A dust box for storing dust, the dust box having an opening; and,
[0022] An exhaust fan, wherein the air inlet of the exhaust fan is connected to the opening via an air duct, and the air outlet of the exhaust fan is directed toward the spring testing machine.
[0023] In one embodiment, the dust concentration regulating mechanism further includes a baffle, one side of which is positioned opposite the air outlet of the exhaust fan. The baffle and the air outlet of the exhaust fan are respectively located on both sides of the length of the spring testing machine to limit the diffusion range of dust.
[0024] In one embodiment, at least a portion of the baffle is inclined toward the direction of the exhaust port of the exhaust fan to form an extension toward the center of the spring testing machine.
[0025] In one embodiment, the spring performance testing apparatus further includes a display device, which is electrically connected to the control device and is used to display the operating data of the spring testing machine and the working condition adjustment mechanism acquired by the control device.
[0026] In one embodiment, the material of the testing chamber includes one of polycarbonate and plexiglass.
[0027] The technical solution of this utility model, by setting the working condition adjustment mechanism in the testing chamber, specifically including a temperature adjustment mechanism, a humidity adjustment mechanism, and a dust concentration adjustment mechanism, allows for the selective placement of these mechanisms within the testing chamber. This simulates various complex working environments for the spring, enabling the testing of spring performance under different temperature, humidity, and dust concentration conditions. Furthermore, by setting the control device, remote control of the spring testing machine and the working condition adjustment mechanism is achieved, facilitating the testing process.

[0037] Currently, most existing brake spring performance testing devices on the market can only conduct tests under a single ambient temperature and pressure environment, which cannot realistically simulate the complex operating conditions of elevators in actual operation. This makes it difficult for the test results to comprehensively and accurately reflect the performance of brake springs in actual use, and thus cannot provide reliable data support for the safe operation of elevators.
[0038] Therefore, designing a testing device and its components for testing the performance of elevator brake springs that can simulate various working conditions is of great practical significance and market demand.
[0039] The main purpose of this invention is to provide a spring performance testing device, which aims to solve the problem that existing spring performance testing devices cannot test the performance of springs under actual complex working conditions.
[0040] To achieve the above objectives, please refer to Figure 1This utility model proposes a spring performance testing device 100 for testing the elastic modulus of a spring 200 under different working conditions. The spring performance testing device 100 includes a testing chamber 1, a working condition adjustment mechanism, a spring testing machine 5, and a control device 6. The working condition adjustment mechanism includes a temperature adjustment mechanism 2, a humidity adjustment mechanism 3, and a dust concentration adjustment mechanism 4, which can be selectively located within the testing chamber 1. The spring testing machine 5 is at least partially located within the testing chamber 1 and is used to measure the elastic modulus of the spring 200. The control device 6 is electrically connected to the spring testing machine 5 and the working condition adjustment mechanism and is used to control the start and stop of the spring testing machine 5 and the working condition adjustment mechanism, as well as to acquire the operating data of the spring testing machine 5 and the working condition adjustment mechanism.
[0041] The technical solution of this utility model, by setting the working condition adjustment mechanism in the testing chamber 1, specifically includes a temperature adjustment mechanism 2, a humidity adjustment mechanism 3, and a dust concentration adjustment mechanism 4. By selectively setting the temperature adjustment mechanism 2, humidity adjustment mechanism 3, and dust concentration adjustment mechanism 4 in the testing chamber 1, various complex working environments of the spring 200 can be simulated to achieve the testing of the spring 200's performance under different temperature, humidity, and dust concentration conditions. Furthermore, by setting the control device 6, remote control of the spring testing machine 5 and the working condition adjustment mechanism can be realized, facilitating the conduct of tests. At the same time, the operating data of the spring testing machine 5 and the working condition adjustment mechanism can be acquired in real time, thereby providing a more intuitive understanding of the spring 200's test performance under different working conditions.
[0042] It is understood that the temperature regulating mechanism 2 is used to regulate the temperature inside the detection chamber 1, the humidity regulating mechanism 3 is used to regulate the humidity inside the detection chamber 1, and the dust concentration regulating mechanism 4 is used to regulate the dust concentration inside the detection chamber 1.
[0043] It is also understood that the optional setting of the temperature regulation mechanism 2, humidity regulation mechanism 3 and dust concentration regulation mechanism 4 means that this solution does not limit the number and type of operating condition adjustment mechanisms, and they can be installed according to actual needs. For example, if the tester only wants to test the performance of spring 200 under different temperature conditions, then only the temperature regulation mechanism 2 needs to be installed in the test chamber. If the tester needs to test the performance of spring 200 under different temperature and humidity conditions, then both the temperature regulation mechanism 2 and the humidity regulation mechanism 3 need to be installed in the test chamber.
[0044] It should be noted that the spring testing machine 5 is existing technology and generally consists of a positioning device, a force application device, a force sensor, and a displacement sensor. The limiting device is used to position the spring 200, the force application device is used to apply external force to the spring 200 so that the spring 200 is compressed or stretched, the force sensor is used to measure the external force on the spring 200, and the displacement sensor is used to measure the deformation of the spring 200. It also includes a calculation module to obtain the elastic modulus of the spring 200 by calculating the data obtained from the force sensor and the displacement sensor. In one embodiment, the force application device of the spring testing machine 5 is located outside the testing chamber 1, and the force application rod of the force application device extends into the testing chamber 1 to act on the spring 200.
[0045] Furthermore, the spring performance testing device 100 also includes a detection mechanism 7, which includes a temperature sensor 71, a humidity sensor 72, and a dust concentration sensor 73. These sensors are selectively located within the testing chamber 1, corresponding to the operating condition adjustment mechanism. It is understood that the detection mechanism 7 is configured in a one-to-one correspondence with the operating condition adjustment mechanism. For example, when a temperature adjustment mechanism is installed in the testing chamber 1, a corresponding temperature sensor 71 must also be installed to obtain the temperature within the testing chamber 1 in real time. Similarly, when both a temperature adjustment mechanism and a humidity adjustment mechanism are installed in the testing chamber 1, corresponding temperature sensors 71 and humidity sensors 72 must be installed to obtain the temperature and humidity within the testing chamber 1 in real time. This configuration allows for real-time acquisition of the specific operating conditions within the testing chamber 1, facilitating the control of the operating condition adjustment mechanism to adjust the operating conditions to the target value, thereby enabling quantitative analysis of the test results.
[0046] In one embodiment of this utility model, the temperature regulating mechanism 2 includes a heater 21, which is used to increase the temperature inside the detection chamber 1. In another embodiment, the temperature regulating mechanism 2 includes a fan 22, which lowers the temperature inside the detection chamber 1 by exchanging air inside and outside the chamber. Either of these two solutions can be chosen, or both can be used simultaneously; this solution does not impose specific limitations. By setting the temperature regulating mechanism 2 as a heater 21 and / or a fan 22, the temperature inside the detection chamber 1 can be controlled in a simple structural form, facilitating subsequent remote control.
[0047] In one embodiment of this utility model, the humidity regulating mechanism 3 includes a humidifier 31 for controlling the humidity inside the detection chamber 1. By setting the humidity regulating mechanism 3 as a humidifier 31, the humidity inside the detection chamber 1 can be controlled in a simple structural form, facilitating subsequent remote control.
[0048] To prevent excessive humidity from causing water accumulation in the testing chamber 1 and affecting the test, a humidity regulating mechanism 3 is installed in the testing chamber 1. The spring performance testing device 100 also includes a water storage tank 8 and a drain pipe 9. The water storage tank 8 is located below the testing chamber 1; the drain pipe 9 connects the water storage tank 8 and the testing chamber 1 to guide water in the testing chamber 1 to the water storage tank 8. This arrangement, by guiding water from the testing chamber 1 to the water storage tank 8, can reduce the impact of water accumulation on the test to a certain extent and improve the accuracy of the test. It is understood that a drain outlet is provided at the bottom of the water storage tank 8 to facilitate the drainage of accumulated water. It is worth mentioning that any device within the testing chamber 1 can be equipped with a drain pipe 9 to facilitate the drainage of accumulated water.
[0049] In one embodiment of this utility model, the dust concentration regulating mechanism 4 includes a dust box 41 and an exhaust fan 42. The dust box 41 is used to store dust and has an opening. The air inlet of the exhaust fan 42 is connected to the opening through an air duct, and the air outlet of the exhaust fan 42 is directed towards the spring testing machine 5. By configuring the dust concentration regulating mechanism 4 as a dust box 41 and an exhaust fan 42, the dust concentration in the testing chamber 1 can be controlled in a simple structural form, facilitating subsequent remote control.
[0050] Furthermore, the dust concentration adjustment mechanism 4 also includes a baffle a, one side of which is positioned opposite the air outlet of the exhaust fan 42. The baffle a and the air outlet of the exhaust fan 42 are respectively located on opposite sides of the length of the spring testing machine 5, used to limit the diffusion range of dust. This arrangement can accelerate the diffusion of dust near the spring testing machine 5, allowing the spring 200 to come into contact with the dust as quickly as possible, so that the working conditions in the testing chamber 1 can meet the standards as soon as possible, thus improving testing efficiency.
[0051] Furthermore, at least a portion of the baffle a is inclined toward the air outlet of the exhaust fan 42 to form an extension toward the center of the spring testing machine 5. This arrangement further restricts the spread of dust, allowing the spring 200 to come into contact with the dust more quickly, thereby further improving testing efficiency.
[0052] To facilitate the observation of test data by the tester, the spring performance testing device 100 also includes a display device b, which is electrically connected to the control device 6 and is used to display the operating data of the spring testing machine 5 and the working condition adjustment mechanism acquired by the control device 6. By setting up the display device b, the tester can more intuitively understand the test data, facilitate real-time control of the test, and promptly detect abnormalities during the test process.
[0053] To ensure the safety and observability of the testing apparatus, the material of the testing chamber 1 includes either polycarbonate or plexiglass. Both polycarbonate and plexiglass are high-strength, transparent materials with a certain degree of corrosion resistance, facilitating direct observation of the testing process while ensuring testing safety, thereby preventing injuries caused by the spring 200 breaking.
[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
