In the traditional manufacturing process of escalator components, each component is inspected, especially the handrail belt.
[0003] Traditional escalator handrail testing simply involves stretching the handrail for inspection, which cannot fully simulate the application environment of the handrail. This results in low testing accuracy and limited testing functionality, reducing the safety factor of the handrail during escalator use. Summary of the Invention
[0004] 1. Technical problems to be solved The purpose of this application is to provide a handrail detection device for escalators, in order to solve the problem that the traditional process of handrail detection for escalators simply involves stretching the handrail for testing, which cannot fully simulate the application environment of the handrail, resulting in low detection accuracy and limited detection function, thus reducing the safety factor of the handrail during the use of escalators.
[0005] The present application provides a handrail detection device for escalators, which adopts the following technical solution: An escalator handrail detection device includes a handrail simulation platform. The handrail simulation platform includes a base, and a guide rail for supporting the handrail belt is provided above the base. Two support plates are provided on the inner side of the guide rail. One side of the support plate is fixed to the top of the base by a fixing bracket. The inner side of the handrail belt is snapped onto the outer surface of the middle part of the guide rail. A detection component mounting bracket is provided between the two support plates. A differential speed detection component, a tension detection component, a displacement clearance detection component, a folding detection component, and a drive component are installed on the detection component mounting bracket.
[0006] The differential detection assembly includes a differential detection wheel, which abuts against the middle outer surface of the armrest belt. The differential detection wheel is located at one end of a rotating shaft, and a speed detection gear is located at the other end of the rotating shaft. A speed detector is located on one side of the speed detection gear. The middle outer surface of the rotating shaft is rotatably mounted inside the middle inner wall of the connecting frame, and the speed detector is mounted on one side of the connecting frame via a fixing bracket.
[0007] The tension detection assembly includes a tension wheel that abuts against the outer surface of the middle part of the handrail belt. The tension wheel is rotatably mounted on one end of the telescopic inner rod of the telescopic rod via a rotating frame. One end of the telescopic outer tube of the telescopic rod is mounted on one side of the detection assembly mounting frame via a fixing frame. A spring is provided on the inner wall of the telescopic rod. One end of the spring is located on one side of a pressure sensor. The pressure sensor is located at one end of the inner wall of the telescopic outer tube of the telescopic rod. The other end of the spring is located at one end of the telescopic inner rod of the telescopic rod.
[0008] The displacement gap detection assembly includes a detection block inserted into the inner side of the handrail belt. The detection block is disposed at one end of the swing rod. The inner wall of the middle part of the swing rod is rotatably disposed on the outer surface of the middle part of the support shaft. The two ends of the support shaft are disposed on one side of the detection assembly mounting frame through fixing brackets. The other end of the swing rod is provided with a sliding frame. A sliding rod is slidably disposed on the inner wall of the middle part of the sliding frame. The two ends of the sliding rod are disposed on both sides of the inner wall of the displacement frame. Two distance sensors are provided at both ends of the displacement frame. The two distance sensors are disposed on both sides of the detection assembly mounting frame through fixing brackets.
[0009] The folding detection component includes two push claws, the inner sides of which abut against the edges of both sides of the handrail belt. The two push claws are located at one end of two electric push rods, and the other ends of the two electric push rods are located on both sides of the detection component mounting frame via a fixing plate.
[0010] The drive assembly includes a drive wheel, the outer surface of the middle part of which abuts against the inner side of the handrail belt, and the drive wheel is located at one end of the output shaft of the second motor.
[0011] By adopting the above technical solution, the handrail is installed on the handrail simulation platform. The contact between the differential speed detection wheel and the handrail allows the handrail to drive the differential speed detection wheel to rotate during operation. Then, through the cooperation of the speed detection gear and the speed detector, the rotational speed of the differential speed detection wheel can be detected in real time, thereby accurately obtaining the operating speed information of the handrail and realizing the detection of the speed difference between the handrail and the main body of the escalator. This avoids safety hazards caused by excessive speed difference and improves the accuracy of differential speed detection. The tensioning wheel in the tensioning detection component contacts the handrail and, under the action of the spring, maintains constant contact with the handrail. The pressure sensor can detect the deformation pressure of the spring, thus reflecting the tension of the handrail and realizing real-time detection of the handrail tension. The detection block in the displacement gap detection component is inserted into the inside of the handrail. The displacement of the handrail will drive the swing rod to swing through the detection block, causing the swing rod to move through the sliding frame and thus the sliding rod to move... The displacement frame moves, and the distance sensor can detect the displacement of the displacement frame, thereby indirectly obtaining the displacement gap information of the handrail belt. This enables the detection of the displacement of the handrail belt during operation. The electric push rod in the folding detection component can drive the push claw to push the two edges of the handrail belt, simulating the folding situation that may occur during use, thus detecting the anti-folding performance of the handrail belt. The drive wheel in the drive component abuts against the inner side of the handrail belt, and under the drive of the second motor, it can drive the handrail belt to run, simulating the actual running state of the handrail belt on the escalator, providing a dynamic detection environment for other detection components. Through the differential speed detection component, tension detection component, displacement gap detection component, folding detection component, and drive component, the handrail belt can be detected from multiple dimensions such as differential speed, tension, displacement gap, and folding performance. This can simulate the running state of the handrail belt in actual application environment, effectively improving the detection accuracy of the handrail belt.
[0012] Preferably, a threaded rod is threaded to the inner wall of one end of the connecting frame, and one end of the threaded rod is located at one end of the output shaft of the first motor. The first motor is mounted on one side of the detection component mounting frame via a fixing plate.
[0013] By adopting the above technical solution, the threaded rod, in conjunction with the first motor, can drive the connecting frame to move, thereby causing the connecting frame to move the differential detection wheel. This adjusts the contact force between the differential detection wheel and the handrail belt, ensuring that the handrail belt can stably drive the differential detection wheel during operation. Simultaneously, the connecting frame can move the differential detection wheel away from the handrail belt, increasing the gap between the handrail belt and the differential detection wheel. This facilitates the installation of the handrail belt on the guide rail, avoiding the influence of the differential detection wheel when installing the handrail belt onto the guide rail.
[0014] Preferably, the outer surface of the middle part of the connecting frame is slidably disposed within the inner wall of the middle part of the limiting frame, and one side of the limiting frame is disposed on one side of the detection component mounting frame through a fixing bracket.
[0015] By adopting the above technical solution, the limiting frame can restrict the sliding direction of the connecting frame, prevent the connecting frame from deviating or shaking during movement, ensure the stability of the contact between the differential detection wheel and the handrail belt, thereby ensuring the accuracy of speed detection and improving the stability of the differential detection component operation.
[0016] Preferably, the support shaft is located at the middle of the swing rod near one end of the detection block.
[0017] By adopting the above technical solution, the support shaft is located in the middle of the swing rod near one end of the detection block. By using the lever principle, the small displacement change of the detection block can be amplified by the sliding frame at the other end of the swing rod, making it easier for the distance sensor to capture the displacement change information, improving the detection sensitivity of the displacement gap detection component. Furthermore, by setting the support shaft close to the detection block, the center of gravity of the swing rod can be adjusted, avoiding the situation where the swing rod swings arbitrarily with a top-heavy weight.
[0018] Preferably, two positioning rods are provided on both sides of the displacement frame via a fixing plate, and the outer surface of the middle part of the two positioning rods is slidably disposed within the inner wall of the middle part of the two positioning frames. The two positioning frames are disposed on one side of the detection component mounting frame via a fixing bracket.
[0019] By adopting the above technical solution, the positioning rod and the positioning frame work together to restrict the movement direction of the displacement frame, prevent the displacement frame from shifting under the action of the sliding frame, ensure the accuracy of the distance sensor in detecting the displacement of the displacement frame, and improve the detection accuracy of the displacement gap detection component.
[0020] Preferably, a rotating roller is rotatably disposed on the inner wall of the push claw near the inner side of the handrail belt. The axial direction of the rotating roller is perpendicular to the running direction of the handrail belt at the push claw, and the outer surface of the middle part of the rotating roller abuts against the outer surface of the middle part of the handrail belt.
[0021] By adopting the above technical solution, the rotating roller can transform the sliding friction between the push claw and the handrail belt into rolling friction, reducing the friction between the push claw and the handrail belt, so that the handrail belt can operate stably between the two push claws, and avoid the smoothness of the handrail belt operation being affected by the push claw.
[0022] Preferably, the second motor is mounted on one end of the hydraulic rod via a fixing bracket, and the other end of the hydraulic rod is mounted on one side of the detection component mounting bracket via a fixing plate.
[0023] By adopting the above technical solution, the hydraulic rod drives the drive wheel to move through the second motor, and the position of the drive wheel is adjusted so that the handrail belt can have enough space to be installed on the guide rail, thus avoiding the influence of the position of the drive wheel when installing the handrail belt.
[0024] Preferably, a notch is provided on one side of the guide rail, and two guide wheels are provided at the end of the notch on one side of the guide rail. The two guide wheels are respectively located on both sides of the drive wheel. The outer surface of the middle part of the two guide wheels abuts against the outer surface of the middle part of the handrail belt. One end of the guide wheel is rotatably disposed on one end of the rotating rod, and the other end of the rotating rod is disposed on one side of the detection component mounting bracket through a fixing bracket.
[0025] By adopting the above technical solution, the opening of the notch on one side of the guide rail provides sufficient space for the drive component to drive the handrail belt to operate. The setting of the guide wheel can cooperate with the drive wheel to guide and support the operation of the handrail belt, so that after the handrail belt is separated from the guide rail through the notch, it can be smoothly locked back onto the guide rail, ensuring the stability of the handrail belt during operation.
[0026] Preferably, the outer surface of the differential detection wheel is provided with an anti-slip pad, and the outer surface of the differential detection wheel is provided with an array of multiple positioning teeth, which are inserted into the inner wall of the anti-slip pad.
[0027] By adopting the above technical solution, the anti-slip pad can increase the friction between the differential detection wheel and the handrail belt, preventing the differential detection wheel from slipping during the rotation of the handrail belt. The positioning teeth can enhance the connection stability between the anti-slip pad and the differential detection wheel, preventing the anti-slip pad from slipping on the outer surface of the middle of the differential detection wheel, ensuring the accuracy of the speed information transmitted by the speed detection gear, and improving the reliability of the differential detection component.
[0028] Preferably, a data processing control host is provided on the top of the base, and the data processing control host is electrically connected to the speed detector, the first motor, the pressure sensor, the distance sensor, the second motor and the hydraulic rod.
[0029] By adopting the above technical solution, the data processing control host can integrate and process the data from detection elements such as speed detectors, pressure sensors, and distance sensors, and control actuators such as the first motor, the second motor, and hydraulic rods. This enables automated operation of the detection process and intelligent data analysis, improving detection efficiency and data processing accuracy, and facilitating the timely detection of problems with the handrail belt.
[0030] 2. Beneficial effects In summary, this application includes at least one of the following beneficial technical effects: 1. This invention provides a handrail detection device for escalators. The handrail belt is supported by a guide rail on a handrail simulation platform, simulating its actual installation environment. A second motor in the drive assembly drives a drive wheel, which in turn drives the handrail belt along the guide rail, simulating the actual operating state. The differential speed detection wheel of the differential speed detection assembly rotates with the handrail belt. A speed detection gear and a speed detector work together to detect the speed and obtain differential speed information. The tension detection wheel of the tensioning assembly abuts against the handrail belt under the action of a spring. A pressure sensor detects the spring deformation pressure to reflect the tension of the handrail belt. The detection block of the displacement gap detection assembly moves with the displacement of the handrail belt, causing a swing rod to swing and a displacement frame to move. A distance sensor detects the distance between the displacement frame and the displacement frame, thus reflecting the displacement of the handrail belt. The electric push rod of the folding detection assembly drives a push claw to push the edge of the handrail belt to detect its anti-folding performance. This device can completely simulate the operating environment of the handrail, simultaneously detecting the tension, differential speed, gap, and state of the handrail belt under operating conditions. This solves the problems of low detection accuracy and limited functionality in traditional methods, improving the safety factor of handrail belt use.
[0031] 2. This invention provides a handrail detection device for escalators. By setting up a threaded rod, a first motor, and a hydraulic rod, when installing the handrail belt, the first motor drives the threaded rod to rotate, causing the connecting frame to move the differential detection wheel away from the handrail belt. The hydraulic rod drives the drive wheel to move away from the inner side of the handrail belt, increasing the installation space of the handrail belt and preventing the differential detection wheel and drive wheel from obstructing the installation of the handrail belt. This allows the operator to more smoothly snap the handrail belt onto the guide rail.
[0032] 3. This invention provides a handrail detection device for escalators. By integrating detection data from a speed detector, pressure sensor, etc., through a data processing control host, it simultaneously controls actuators such as a first motor, a second motor, and a hydraulic rod, realizing automated adjustment and intelligent data analysis of the detection process. This improves the flexibility, efficiency, and accuracy of data processing, and facilitates the rapid detection of problems with the handrail. Attached Figure Description

The hydraulic rod 803 drives the second motor 802 to move, causing the second motor 802 to drive the drive wheel 801 to move towards the detection component mounting bracket 2. The drive wheel 801 moves inward toward the inside of the handrail belt 3, thus making the drive wheel 801 tightly abut against the inside of the handrail belt 3. The first motor 407 drives the threaded rod 406 to rotate, causing the connecting bracket 405 to drive the differential detection wheel 401 to move closer to the handrail belt 3, so that the differential detection wheel 401 tightly abuts against the outer surface of the middle part of the handrail belt 3 through the anti-slip pad 12, completing the installation of the handrail belt 3. The second motor 802 works, driving the drive wheel 801 to rotate, causing the drive wheel 801 to drive the handrail belt 3 to run. During the operation of the handrail belt 3, the differential detection wheel 401 of the differential detection assembly 4 rotates with the handrail belt 3, and the rotating shaft 402 drives the speed detection gear 403 to rotate, and the speed detector 40... 4. The rotational speed detection gear 403 detects the rotational speed information and transmits it to the data processing control host 10 to detect the running speed of the handrail belt 3 and the difference between it and the drive speed. The tension wheel 501 of the tension detection component 5 abuts against the handrail belt 3 under the action of the spring 503. The tension change of the handrail belt 3 will cause the spring 503 to deform. The pressure sensor 504 detects the pressure change and transmits the data to detect the tension of the handrail belt 3 during operation. The detection block 601 of the displacement clearance detection component 6 drives the swing rod 602 to swing with the displacement of the handrail belt 3. The swing of the swing rod 602 can cause the sliding frame 604 to drive the sliding rod 605 to move, so that the sliding rod 605 drives the displacement frame 606 to move linearly. Distance sensor Device 607 detects the displacement change of displacement frame 606 and transmits data, thereby detecting the displacement of handrail belt 3. The two electric push rods 702 of the flip detection component 7 work independently, pushing a single push claw 701 to push one edge of the handrail belt 3, which can detect the anti-flipping performance of the handrail belt 3. The two electric push rods 702 work synchronously, causing the two push claws 701 to push the edges of both sides of the handrail belt 3, which can simulate the lifting action of the handrail belt 3 and detect the anti-flipping and anti-lifting performance of the handrail belt 3. The data processing control host 10 integrates and analyzes the data transmitted by each component, and completes the multi-dimensional automated detection of the handrail belt 3 under the simulated actual operation of the handrail belt 3.
