Description

Technical Field

[0001] The invention relates to the technical field of anti-skid performance testing devices, in particular to an on-site anti-skid testing device for escalator tread panels. Background Art

[0002] Existing escalators are usually equipped with escalator treads at the entrance of the escalator. The escalator treads can be used for passengers to stand and walk, and have the function of bearing the weight of passengers and realizing personnel transportation. In order to avoid congestion caused by people staying at the entrance of the escalator, passengers need to pass the escalator treads as soon as possible to ensure the smooth operation of the escalator. The anti-slip performance of the escalator treads is particularly important. Escalator treads with poor anti-slip performance can easily cause passengers to slip and get injured when walking, affecting the safety of escalator use.

[0003] Before the escalator tread panels are installed on site, they need to be tested for anti-skid performance. Currently, the anti-skid performance test of escalator tread panels before installation is usually completed in the laboratory. The anti-skid performance test device used in the laboratory usually places the test sample on an inclined platform, and the tester walks on the test sample according to the beat until the tester loses balance, and the anti-skid performance of the test sample is obtained through the inclination data. However, after the escalator tread panels are put into use, as the use time accumulates, the surface of the escalator tread panels will show different degrees of wear, which will affect the anti-skid performance. Therefore, after the escalator tread panels are put into use, they need to be tested for anti-skid performance regularly so as to perform maintenance and update operations in time. When the anti-skid performance test of the escalator tread panels that have been put into use is carried out, it is usually necessary to dismantle the escalator tread panels at the site of use and bring them back to the laboratory for testing. The on-site disassembly and assembly is troublesome, and after the escalator tread panels are disassembled, it is necessary to strictly prevent pedestrians from stepping into the air, which makes it inconvenient to perform anti-skid tests on the escalator tread panels used on site.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance.

[0034] like Figures 1 to 5As shown, an on-site anti-skid testing device for escalator treads comprises a bracket 1, a tilting drive mechanism 2 and a stepping mechanism 3;

[0035] The stepping mechanism 3 includes a mounting plate 31, a first driving device 32, a pressure sensor 33, a test shoe 34 and an angle sensor 35, wherein the first driving device 32 is hinged to the mounting plate 31, one end of the pressure sensor 33 is fixedly connected to the output shaft of the first driving device 32, and the other end of the pressure sensor 33 is connected to the test shoe 34;

[0036] The bracket 1 is provided with a stepping hole 11 at a position below the stepping mechanism 3, and the stepping hole 11 allows the test shoe 34 to pass through and step on the escalator tread plate; the first driving device 32 drives the test shoe 34 to approach or move away from the stepping hole 11, so that the test shoe 34 steps on the surface of the escalator tread plate;

[0037] The tilting driving mechanism 2 is fixedly arranged on the bracket 1, and the driving end of the tilting driving mechanism 2 is transmission-connected with the mounting plate 31, and the tilting driving mechanism 2 is used to drive the mounting plate 31 to rotate relative to the bracket 1 to change the tilting angle of the first driving device 32;

[0038] The angle sensor 35 is fixedly disposed on the mounting plate 31 , and the angle sensor 35 is used to test the tilt angle of the first driving device 32 .

[0039] At present, it is difficult to directly test the anti-skid performance of the escalator tread panels on site. The on-site anti-skid testing device for escalator tread panels of the present invention is provided with the stepping mechanism 3. During the test, the bracket 1 is placed on the surface of the escalator tread panel to be tested on site. Since the bracket 1 is provided with the stepping opening 11 at the lower position corresponding to the stepping mechanism 3, the first driving device 32 drives the tested shoe 34 to approach or move away from the stepping opening 11, so that the tested shoe 34 passes through the stepping opening 11 and steps on the escalator tread panel to perform stepping motion.

[0040] When the test shoe 34 contacts the escalator tread, it fits with the escalator tread, simulating the movement of a person's foot stepping on the escalator tread. The test shoe 34 generates a friction force F due to the contact between the test shoe 34 and the escalator tread. 摩 (Along the escalator tread direction opposite to the sliding direction of the test shoe 34), the pressure sensor 33 can test the F of the test shoe 34 at different angles. 摩 The support force F of the escalator tread 支 The resultant force F 合 , the support force F of the escalator tread on the test shoe 34 支Vertical escalator tread upward, F 合 is the force value collected by the pressure sensor 33 .

[0041] Unlike the laboratory test in which the tilt angle of the test sample is changed, the tilt angle of the escalator tread panel on site cannot be changed. The present invention sets the tilt drive mechanism 2 to change the tilt angle of the first drive device 32, so that the first drive device 32 rotates a certain angle relative to the escalator tread panel. When the first drive device 32 drives the test shoe 34 to step on the escalator tread panel in an inclined state, the test shoe 34 will generate a tilt pressure F inclined downward on the escalator tread panel. 斜 . Preset a tilt pressure F 斜 , this F 斜 represents the tilt pressure F exerted by the test shoe 34 on the escalator tread under normal conditions, such as when the weight of the person is 60 kg. 斜 , where the tilt pressure F 斜 The force value F collected by the pressure sensor 33 合 When the test shoe 34 steps on the escalator tread plate, the first driving device 32 drives the test shoe 34 to apply an inclined pressure F on the surface of the escalator tread plate. 斜 The tilt drive mechanism 2 drives the mounting plate 31 to rotate, so that the tilt angle of the first drive device 32 changes. The tilt drive mechanism 2 drives the first drive device 32 to rotate to a preset angle, and can also gradually increase the tilt angle of the first drive device 32 from 0°. At each tilt angle, the test shoe 34 can simulate the stepping motion of a person on the escalator tread panel at the scene under the drive of the first drive device 32, and judge whether the test shoe 34 slides on the escalator tread panel at the scene through the reading of the pressure sensor 33:

[0042] 1. No sliding: When the reading F of the pressure sensor 33 合 Can stably reach the preset F 斜 (For example, the tilt pressure applied to the escalator tread when the weight of a person is 60 kg), that is, the first driving device 32 drives the test shoe 34 to pressurize the surface of the escalator tread to reach F 斜 , it indicates that the friction between the test shoe 34 and the escalator tread is large enough to prevent the test shoe 34 from sliding on the escalator tread. At this time, it is determined that the test shoe 34 does not slide on the escalator tread;

[0043] 2. Sliding condition: When the reading F of the pressure sensor 33 合 Unable to reach the preset F 斜When the pressure is greater than F (e.g., the tilt pressure applied to the escalator tread when the weight of a person is 60 kg), or when the pressure is reached but cannot be maintained stably (i.e., the value cannot be increased or begins to fluctuate), the first driving device 32 drives the test shoe 34 to pressurize the surface of the escalator tread and cannot reach F. 斜 , it proves that the friction between the test shoe 34 and the escalator tread plate is insufficient to prevent the sliding of the test shoe 34. At this time, it is judged that the test shoe 34 will slide on the surface of the escalator tread plate, and the inclination angle of the first driving device 32 when sliding occurs is recorded, and this angle is the critical angle of slipping.

[0044] When evaluating the anti-slip performance, the larger the critical slip angle, the more stable the test shoe 34 can remain without slipping at a larger tilt angle. Therefore, the larger the critical slip angle, the better the anti-slip performance of the escalator tread test position.

[0045] The on-site anti-skid testing device for escalator treads can simulate the situation where people step on the on-site escalator treads, and can directly perform anti-skid testing on the escalator treads at the use site of the escalator treads. The test is convenient, and there is no need to disassemble and assemble the on-site escalator treads, and the safety hazards caused by disassembling the escalator treads are avoided. The technical problems of troublesome disassembly and assembly when performing anti-skid testing on the on-site escalator treads, poor safety after disassembling the escalator treads, and inconvenience in performing anti-skid testing on the on-site are solved.

[0046] In addition, due to the trampling habits of pedestrians, a certain position of the escalator tread panel may be relatively severely worn, while the other positions may be relatively less worn. By setting the bracket 1, when it is necessary to test the anti-skid performance of different positions of the on-site escalator tread panel, the bracket 1 can be directly moved to move the on-site anti-skid test device of the escalator tread panel to the position to be measured, which is convenient for measuring the anti-skid performance of different positions of the on-site escalator tread panel, and provides a more comprehensive test reference for subsequent maintenance. The sliding state can be obtained through the value of the pressure sensor 33, avoiding subtle sliding and other situations that are difficult for the human eye to observe, and the test accuracy is high.

[0047] To further explain, in the initial state before the test (such as Figure 1 As shown in the figure), the test shoe 34 is arranged horizontally, and the first driving device 32 is arranged vertically;

[0048] The stepping mechanism 3 also includes a pedaling angle adjustment component 36, which includes a servo 361 and a connecting frame 362. The servo 361 is fixedly arranged at one end of the angle sensor 35 away from the first driving device 32, and the output end of the servo 361 is connected to the connecting frame 362. The end of the connecting frame 362 away from the angle sensor 35 is fixedly connected to the test shoe 34.

[0049] In the initial state before the test, the test shoe 34 is set horizontally and the first drive device 32 is set vertically. When the tilt drive mechanism 2 drives the first drive device 32 to rotate to a larger preset angle, the test shoe 34 will also follow the first drive device 32 to rotate to a corresponding angle. After rotating to a certain angle, the angle between the test shoe 34 and the escalator tread is the original tilt angle. At this time, when the first drive device 32 drives the test shoe 34 to step on the surface of the escalator tread, since the original tilt angle between the test shoe 34 and the escalator tread is large (such as Figure 6 As shown in the figure, the test shoe 34 may fall onto the escalator tread panel with the heel of the shoe as the contact point. Under the driving pressure of the first driving device 32, it may directly fall onto the surface of the escalator tread panel with a smaller contact point, which may easily cause abnormal sliding, thereby affecting the test accuracy.

[0050] By setting the stepping angle adjustment assembly 36, the steering engine 361 drives the connecting frame 362 to rotate, so that the angle between the test shoe 34 and the escalator tread plate is reduced. At this time, the steering engine 361 of the stepping angle adjustment assembly can correct the inclination angle of the test shoe 34 (such as Figure 7 The figure shows the stepping angle after correction), the angle at which the steering gear 361 drives the connecting frame 362 to rotate is the correction angle, and the stepping angle of the test shoe 34 on the escalator tread panel after correction = the original tilt angle - the correction angle. The correction of the original tilt angle of the test shoe 34 by the stepping angle adjustment component 36 can eliminate the abnormal sliding situation that occurs during the stepping process, so that no matter how large the preset angle of the first driving device 32 is rotated, the stepping angle of the test shoe 34 is basically the same each time, ensuring the consistency of the test. The stepping angle is preferably 3°. In addition, in the laboratory anti-skid test device, when the tester directly steps on the inclined platform, as the tilt angle of the inclined platform gradually increases, the psychological reaction of the tester usually drives him to step as close to the tilt angle of the inclined platform as possible when stepping, that is, he usually steps on the test sample at a smaller angle. The on-site anti-skid test device for escalator tread panels corrects the stepping angle, so that the test shoe 34 is close to the stepping angle that the real tester naturally adapts to when stepping, effectively improving the test accuracy.

[0051] Specifically, the first driving device 32 is an electric cylinder, which has strong driving stability and high driving accuracy.

[0052] Specifically, the first driving device 32 and the pressure sensor 33 are arranged perpendicularly, and the pressure sensor 33 can measure the tilt angle of the first driving device 32 , which is the angle between the first driving device 32 and a vertical plane.

[0053] To further explain, the stepping mechanism 3 further includes a supporting gasket 37 , and the end of the connecting frame 362 away from the angle sensor 35 is fixedly connected with the supporting gasket 37 , and the supporting gasket 37 is detachably connected to the test shoe 34 .

[0054] By providing the support gasket 37, the support gasket 37 is detachably connected to the test shoe 34, and the tilt pressure during the test can be transmitted through the support gasket 37. As the number of tests accumulates, the test shoe 34 may be damaged. The detachable connection between the support gasket 37 and the test shoe 34 can facilitate replacement and maintenance of the test shoe 34, thereby extending the service life of the escalator tread panel on-site anti-slip test device.

[0055] Specifically, a rotating shaft 311 is provided on the surface of the mounting plate 31, and a first hinge seat 321 is provided at the end of the first driving device 32 away from the test shoe 34. The first hinge seat 321 is provided with a through hole matching the rotating shaft 311, and the rotating shaft 311 is inserted into the through hole and hinged to the first hinge seat 321.

[0056] By arranging a rotating shaft 311 on the surface of the mounting plate 31, the rotating shaft 311 is inserted into the through hole and hinged to the first hinge seat 321, so that the first driving device 32 is hinged to the mounting plate 31, and when the friction between the test shoe 34 and the escalator tread is insufficient to prevent the test shoe 34 from sliding, the test shoe 34 can slide.

[0057] Specifically, the bracket 1 is a support frame composed of a plurality of profiles. The bracket 1 is provided with an escape opening 12 at one end thereof corresponding to the test shoe 34 away from the first driving device 32 , and the escape opening 12 is for the test shoe 34 to pass through when sliding.

[0058] By configuring the bracket 1 as a support frame composed of multiple profiles, the support stability is strong, and the bracket 1 is provided with the avoidance opening 12. When the test shoe 34 slides, the test shoe 34 slides toward the avoidance opening 12, thereby preventing the test shoe 34 from colliding with the bracket 1 when sliding.

[0059] Preferably, a foot pedal 13 is provided at the bottom of the bracket 1 , and the foot pedal 13 is symmetrically arranged on two side surfaces of the bracket 1 .

[0060] During the test process, the driving force of the first driving device 32 on the test shoe 34 will cause the bracket 1 to have an upward lifting reaction force, and this reaction force will deteriorate the stability of the test process.

[0061] By providing the foot pedal 13, during the test, the tester steps on the foot pedal 13 to offset the reaction force of the first driving device 32 on the bracket 1, thereby improving the stability of the device during the test and ensuring the test accuracy.

[0062] Preferably, the foot pedal 13 can be a foldable foot pedal 13, which is convenient for carrying the escalator tread panel on-site anti-slip testing device. The foot pedal 13 can be folded during transportation to avoid collision of the protruding foot pedal 13 during transportation.

[0063] Further, the tilt drive mechanism 2 includes a second drive device 21 and a fixing plate 22, the fixing plate 22 is fixedly arranged on the bracket 1, one end of the second drive device 21 is hinged to the bracket 1, the other end of the second drive device 21 is connected to a ball head 211, and a ball joint seat 312 is provided on the surface of the mounting plate 31, and the ball head 211 is hinged in the ball joint seat 312;

[0064] A curved guide rail 221 is disposed on one side of the fixing plate 22 close to the mounting plate 31 , and a pulley 313 is disposed on one side of the mounting plate 31 close to the fixing plate 22 . The pulley 313 is slidably disposed on the curved guide rail 221 .

[0065] By arranging the arc guide rail 221 on the fixing plate 22, when the second driving device 21 drives the mounting plate 31 to move, the pulley 313 drives the mounting plate 31 to slide along the arc guide rail 221, thereby realizing the rotation of the mounting plate 31, so that the first driving device 32 also rotates relative to the bracket 1, thereby changing the tilt angle of the first driving device 32. By arranging the ball joint seat 312 on the surface of the mounting plate 31, and connecting the ball head 211 to the second driving device 21, the ball head 211 is hinged in the ball joint seat 312, and can adapt to the tilt angle of the mounting plate 31. The second driving device 21 is hinged with the bracket 1. When the mounting plate 31 rotates, the second driving device 21 can also adaptively rotate a certain angle, so that the rotation of the mounting plate 31 is smooth.

[0066] Specifically, the second driving device 21 is an electric cylinder, and the output shaft of the second driving device 21 is connected to the ball head 211, so the driving stability is strong and the driving precision is high.

[0067] Preferably, a support pin 222 is provided on a side of the fixing plate 22 close to the mounting plate 31 , and the support pin 222 is arranged on a side of the first driving device 32 away from the avoidance opening 12 , and a side wall of the first driving device 32 abuts against the support pin 222 .

[0068] By setting the support pin 222, the support pin 222 plays a role of supporting the first driving device 32, and cooperates with the tilting driving mechanism 2 to realize the rotation of the first driving device 32, and makes the test shoe 34 only slide toward one side of the avoidance opening 12. When the test shoe 34 is not in contact with the escalator tread panel, the first driving device 32 lightly leans against the support pin 222 and abuts against the support pin 222.

[0069] Specifically, the bracket 1 is provided with a second hinge seat 14 , and one end of the second driving device 21 away from the mounting plate 31 is hinged to the second hinge seat 14 .

[0070] By providing the second hinge seat 14, the second drive device 21 is hinged to the bracket 1. When the mounting plate 31 rotates, the second drive device 21 can also adaptively rotate a certain angle. Specifically, the second hinge seat 14 can be connected to the second drive device 21 through a pin.

[0071] To further explain, the escalator tread on-site anti-slip testing device also includes a controller 4 and a display screen 5 . The controller 4 and the display screen 5 are respectively fixedly disposed on the bracket 1 , and the controller 4 is connected to the display screen 5 .

[0072] By providing the controller 4 and the display screen 5, the escalator tread on-site anti-skid testing device can be operated and controlled, and the anti-skid test results can be conveniently viewed.

[0073] Specifically, the first drive device 32, the pressure sensor 33, the angle sensor 35, the steering gear 361 and the second drive device 21 are electrically connected to the controller 4 respectively, and the controller 4 controls the operation of the first drive device 32 and the steering gear 361, thereby controlling the stepping motion of the test shoe 34 and adjusting the stepping angle; the controller 4 controls the operation of the second drive device 21 to control the second drive device 21 to drive the mounting plate 31 to rotate to a preset angle. The controller 4 can also obtain the signals transmitted by the pressure sensor 33 and the angle sensor 35, and evaluate the anti-slip performance of the escalator tread plate through the measured data.

[0074] It should be noted that the controller 4 can also be connected to a handheld terminal such as a tablet computer, a mobile phone, etc. In order to ensure the stability of the device, when the tester steps on the foot pedal 13 with both feet, it is difficult to observe the sliding state of the test shoe 34 and the test result of the display screen 5. By connecting the controller 4 to the handheld terminal, the tester can view the test result through the handheld terminal with both feet on the foot pedal 13, and there is no need for multiple testers to go to the site to perform test operations (for example, one tester steps on the foot pedal 13, and another tester performs test control and views the test results).

[0075] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
