Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a roller testing device. Background Technology

[0002] Guide shoes are sliding nylon blocks between the elevator guide rails and the car. They secure the car to the guide rails, allowing it to move only up and down. Each elevator car is equipped with four sets of guide shoes, installed on both sides of the upper beam and below the safety gear seat at the bottom of the car. Four sets of counterweight guide shoes are installed at the bottom and top of the counterweight beam. The guide shoes fixed to the car can move back and forth along the fixed guide rails installed on the building shaft walls, preventing the car from tilting or swaying during operation. Elevator guide shoes are divided into rolling guide shoes and sliding guide shoes. Rolling guide shoes, also known as roller guide shoes, use 3 or 6 wheels that are engaged with the guide rails. During elevator operation, the rollers are in direct contact with the guide rails. Therefore, the service life of the rollers directly affects the service life of the roller guide shoes and the safety performance of the elevator. Existing roller testing equipment generally tests the roller's ultimate service life by pressing the roller against the rotating wheel and rolling it for a long time. This testing method cannot effectively simulate the working conditions of the rollers and therefore cannot accurately test the service life of the rollers under real conditions. Therefore, a roller testing device is needed to detect the service life of the rollers. Utility Model Content

Detailed Implementation

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See Figures 1 to 3 This utility model provides a roller testing device, characterized in that it includes:

[0027] Rack 1;

[0028] A rotating mechanism 2 is disposed in the middle of the frame 1. The rotating mechanism 2 includes a test rotating wheel 201 and a rotating wheel drive device 202. The test rotating wheel 201 is connected to the rotating wheel drive device 202 in a transmission manner. The rotating wheel drive device 202 is used to drive the rotating wheel to rotate in both directions.

[0029] The test mechanism 3 is mounted on the frame 1. The test mechanism 3 includes a roller frame 301 and a test drive device 302. The roller frame 301 is used to mount the roller to be tested. The roller frame 301 is connected to the test drive device. The test drive device is used to drive the roller frame 301 to move relative to the roller.

[0030] Temperature detection mechanism 4 is mounted on the frame 1 and corresponds to the position of the roller frame 301. Temperature detection mechanism 4 is used to measure the temperature of the edge of the roller to be measured.

[0031] The controller 5 is electrically connected to the rotary drive device 202, the test drive device 302, and the temperature detection mechanism 4.

[0032] This utility model provides a roller testing device, characterized in that it includes: a frame 1, a rotating wheel mechanism 2, a testing mechanism 3, a temperature detection mechanism 4, and a controller 5. In use, the roller to be tested is mounted on the roller frame 301. The testing drive mechanism drives the roller frame 301 to move, causing the roller to be tested and the testing rotating wheel 201 to come into contact, forming a friction transmission pair. The rotation drive device drives the testing rotating wheel 201 to rotate in both directions, thereby driving the roller to be tested to rotate in both directions. This can simulate the forward and reverse rotation of the roller during the up and down movement of an elevator car, making the test more accurate. The temperature detection mechanism 4 is used to detect the temperature change of the roller under long-term operation during the test. It can also measure the service life of the roller under extreme conditions, and can keep the roller under test within a certain temperature range during testing, thereby eliminating the influence of temperature on the service life of the roller under test and making the test results more accurate.

[0033] In a further embodiment of this invention, the testing mechanism 3 further includes a guide rail 303, and the roller frame is disposed on the guide rail 303, and the roller frame can slide on the guide rail 303.

[0034] In this embodiment, the testing mechanism 3 further includes a guide rail 303. The testing drive device 302 can drive the roller frame to slide on the guide rail 303, which can make the movement of the roller frame 301 more stable. When the roller to be tested abuts against the rotating wheel, the guide rail 303 can restrict the roller frame 301 from moving to both sides, which can ensure that the roller frame 301 will not be biased, thereby ensuring testing accuracy and reducing safety hazards.

[0035] In a further embodiment of this invention, the test drive device 302 is a servo drive motor.

[0036] In this embodiment, the test drive device 302 is a servo drive motor, which can accurately control the movement stroke of the roller frame to ensure that the roller under test abuts against the test roller 201, thereby ensuring test accuracy.

[0037] In a further embodiment of this embodiment, the roller frame 301 includes a positioning shaft 304 and a fixing member 305. The upper part of the positioning shaft 304 is provided with a mounting part 306. The fixing member 305 is detachably connected to the positioning shaft 304. The lower surface of the fixing member 305 cooperates with the mounting part 306 to form a mounting groove 307.

[0038] In this embodiment, the roller frame 301 includes a positioning shaft 304 and a fixing member 305. In use, the fixing member 305 is first removed from the positioning shaft 304, then the center hole of the roller to be tested is fitted into the mounting part 306, the fixing member 305 is installed on the top of the positioning shaft 304, and then the fixing member 305 is fixedly connected to the positioning shaft 304 using fasteners. The lower surface of the fixing member 305 cooperates with the mounting part 306 to form a mounting groove 307. The mounting groove 307 can limit the position of the roller to be tested, ensuring that the roller to be tested can abut against the test roller, improving the convenience of operation. The mounting groove 307 can also limit the movement of the roller to be tested, preventing the roller to be tested from detaching from the roller frame 301 during the test, which can reduce safety hazards.

[0039] In a further embodiment of this invention, the temperature detection mechanism 4 includes a detection bracket 401 and a temperature sensor 402. The detection bracket 401 is disposed on the frame 1, and the temperature sensor 402 is disposed on the detection bracket 401.

[0040] In this embodiment, the temperature detection mechanism 4 includes a detection bracket 401 and a temperature sensor 402. The temperature sensor 402 is disposed on the detection bracket 401. When the roller to be tested abuts against the test wheel 201, the temperature sensor 402 is fixed above the roller to be tested by the detection bracket 401 to ensure the detection accuracy of the temperature sensor 402.

[0041] In a further embodiment of this invention, the temperature sensor 402 is a laser temperature sensor 402.

[0042] In this embodiment, the temperature sensor 402 is a laser temperature sensor 402. During testing, the laser beam emitted by the laser temperature sensor 402 is directed toward the edge of the roller to be tested, forming a detection point. The detection point is located close to the position that contacts the test roller 201, ensuring the accuracy of the measured temperature.

[0043] In a further embodiment of this invention, the rotary drive mechanism is fixed to the lower part of the frame 1, the rotary wheel is disposed on the upper part of the frame 1, and the rotary drive mechanism passes through the frame 1 and is connected to the rotary wheel via a transmission.

[0044] In this embodiment, the rotary drive mechanism is fixed to the lower part of the frame 1, which can avoid interference between the rotary drive mechanism and the testing mechanism 3 and the temperature detection mechanism 4, thereby reducing safety hazards and improving operational convenience.

[0045] In a further embodiment of this invention, the rotary drive mechanism is a drive motor.

[0046] In this embodiment, the rotating wheel drive mechanism is a drive motor, which can accurately control the forward and reverse rotation of the rotating wheel, thereby more accurately simulating the working condition of the roller and improving the detection accuracy.

[0047] In a further embodiment of this example, there are four testing mechanisms 3 and four temperature detection mechanisms 4. The four testing mechanisms 3 are evenly distributed on the frame 1, and the four temperature detection mechanisms 4 are evenly distributed on the frame 1.

[0048] In this embodiment, the frame 1 has 4 workstations, and the 4 testing mechanisms 3 and 4 temperature detection mechanisms 4 are arranged on the 4 workstations, so that the testing equipment can test 4 rollers to be tested at one time, thereby improving the testing efficiency.

[0049] In a further embodiment of this example, the controller 5 is a programmable controller 5.

[0050] In this embodiment, the controller 5 is a programmable logic controller (PLC). The PLC can control and record the working state of the rotary drive device 202 and the test drive device 302. It can also receive and record the temperature signal emitted by the temperature sensor 402. The test drive device 302 is a servo drive motor. When the servo drive motor drives the roller frame 301 to move, when the roller under test comes into contact with the test rotary wheel 201, the electrical signal fed back by the servo drive motor will change due to the change in resistance. The controller 5 will control the servo drive motor to stop running according to the received change in electrical signal, so that the roller under test stops pressing the test rotary wheel 201 after it comes into contact with the test rotary wheel 201, avoiding the deformation of the roller under test and ensuring the test accuracy.
