An escalator step detachment detection device

Abstract

This invention discloses an escalator step detachment detection device, belonging to the field of step detachment detection technology. This escalator step detachment detection device includes a frame, with a protective translation component and a buffer protection component installed on the outer wall of the frame. Through hydraulic oil compression, a first sliding column drives a first moving block to slide, causing a sliding shell, a sliding plate, and a first baffle to slide simultaneously along a second slide rail. This provides ample space for elevator maintenance, facilitating repairs and reducing disassembly time. Hydraulic oil in the support plate pushes a second limit block to mechanically brake the power-off elevator, ensuring passenger safety. Workers can determine the repair location by observing the compression block in the receiving shell, reducing repair time. When the step collides with the second buffer plate, it rebounds, contacting and compressing the second baffle, compressing the spring and providing buffer protection for the step and elevator components.

The escalator step detachment detection device includes a frame, a protective translation component, and a buffer protection component. After the step falls off, the protective mechanism makes the step land stably on the buffer plate. Finally, the translation mechanism reduces the time spent by the staff for maintenance.

[0003] Chinese patent CN119100237A, authorized and published on December 10, 2024, discloses an escalator step loss detection device. It is installed in the escalator installation chamber through a multi-directional adjustment frame, and the multi-directional adjustment frame is provided with a height adjustment seat, an angle adjustment bracket and a cable winding hook.

[0011] Furthermore, the first sliding block forms a telescopic structure with the first sliding cylinder through the first buffer spring, and the first slider forms a telescopic structure with the second sliding cylinder through the first limiting spring.

[0012] Furthermore, the first limiting cylinder forms a telescopic structure with the sliding plate via a tension spring, the first moving block is slidably connected to the second slide rail via a first sliding column, and a connecting block is fixedly connected to the outer wall of the second baffle.

[0013] Furthermore, the second sliding block forms a telescopic structure with the limiting ring via the second buffer spring, the propulsion cylinder forms a telescopic structure with the limiting groove via the second limiting spring, and the support plate is fixedly connected to one end of the torsion spring.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) In this invention, when the step falls off and contacts and squeezes the second buffer plate, the hydraulic oil in the support plate is squeezed, and the hydraulic oil pushes the push rod to slide. The push rod drives the second moving block to slide synchronously. When the step collides with the second buffer plate, it rebounds and contacts and squeezes the second stop, causing the second stop to slide along the inner wall of the second moving block. The sliding of the second stop causes the compression spring to be squeezed, thus providing buffer protection for the step and elevator parts. (2) The sliding plate is protected by the tension spring to avoid damage to elevator parts. The hydraulic oil in the second groove pushes the first sliding column to slide through the hole. The first sliding column drives the first moving block to slide along the second slide rail. The sliding shell drives the sliding plate to slide. At this time, the sliding shell drives the first sliding rod to slide along the second sliding rod, so that the sliding shell, the sliding plate and the first baffle slide along the second slide rail at the same time, thereby leaving enough space for the staff to maintain the elevator, making maintenance convenient and reducing the time spent on disassembly.

[0017] (3) When the steps contact and squeeze the second buffer plate, the second buffer spring is squeezed to buffer the steps and prevent them from falling and being damaged. The hydraulic oil in the support plate pushes the second sliding column to slide. The second sliding column drives the second limit block to slide synchronously, so the second limit block locks the elevator running shaft and mechanically brakes the power-off elevator to fully brake the elevator and ensure the safety of passengers. The second push column squeezes the extrusion block out of the receiving shell. During maintenance, the staff can determine the maintenance position by observing the extrusion block in the receiving shell, reducing unnecessary disassembly and reducing maintenance time. When the steps contact and squeeze the extrusion plate, the second limit spring is squeezed to buffer and protect the steps, reducing damage to the steps. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0022] Please see Figure 1 - Figure 18This invention provides a technical solution: an escalator step detachment detection device, comprising a frame 1, a protective translation component and a buffer protection component disposed on the outer wall of the frame 1, the protective translation component including a protection mechanism and a translation mechanism, the protection mechanism including a first fixed plate 2 fixedly connected to the outer wall of the frame 1, a sliding shell 5 slidably connected to the outer wall of the first fixed plate 2, a sliding plate 6 slidably connected to the inner wall of the sliding shell 5, a first baffle 7 fixedly connected to the outer wall of the sliding plate 6, a first slide cylinder 12 fixedly connected to the inner wall of the sliding plate 6, a first channel 14 and a first slide groove 15 formed on the inner wall of the sliding plate 6, a first stop block 16 adapted to the first slide groove 15 disposed on the inner wall of the sliding plate 6, a first buffer spring 13 fixedly connected to the inner wall of the sliding plate 6, a first buffer plate 10 slidably connected to the inner wall of the sliding plate 6, a first sliding block 11 fixedly connected to the outer wall of the first buffer plate 10, and a first camera mounted on the outer wall of the sliding plate 6. 65. A second sliding cylinder 19 is fixedly connected to the inner wall of the sliding plate 6. A first limiting plate 17 is slidably connected to the inner wall of the sliding plate 6. A first slider 18 and a first limiting spring 20 are fixedly connected to the outer wall of the first limiting plate 17. A second sliding groove 22 is formed on the inner wall of the sliding plate 6. A first pushing block 21 adapted to the second sliding groove 22 is provided on the outer wall of the first buffer plate 10. A second channel 23 is formed on the inner walls of both the sliding plate 6 and the first baffle 7. The inner wall of the first baffle 7 slides... A telescopic rod 71 is connected, and a connecting block 70 is slidably connected to the outer wall of the telescopic rod 71. A first groove 25 is provided on the inner wall of the connecting block 70, and a first limiting block 26 adapted to the first groove 25 is provided on the inner wall of the connecting block 70. A first pushing column 24 is fixedly connected to the outer wall of the first limiting block 26. The first sliding block 11 forms a telescopic structure with the first sliding cylinder 12 through the first buffer spring 13. The first slider 18 forms a telescopic structure with the second sliding cylinder 19 through the first limiting spring 20.

[0023] In operation, when a passenger steps onto the escalator via the first fixed plate 2, the escalator steps are suddenly subjected to force. If a step detaches along the outer wall of the frame 1, the passenger will fall and suffer initial injury. The first camera 65 captures the step detachment and transmits the image information to the escalator power control system. The power control system analyzes and processes the signal, confirming the step detachment. Upon confirmation, it sends a control signal, triggering a safety relay to shut off the escalator power, preventing further injury to the passenger. After detachment, the step contacts and presses against the first buffer plate 10, causing it to slide along the inner wall of the sliding plate 6 towards the first buffer spring 13. The sliding plate 6 slides along the inner wall of the sliding shell 5. The sliding of the first buffer plate 10 drives the first push block 21 to slide synchronously along the second slide groove 22, allowing hydraulic oil in the second channel 23 to enter the telescopic rod 71. This pushes the first push column 24 along the inner wall of the connecting block 70, causing the first push column 24 to slide. The sliding of the first push column 24 then drives the first limit block 26. The elevator slides synchronously along the first groove 25, thereby engaging the first limit block 26 with the elevator shaft, mechanically braking the elevator in the event of a power outage, ensuring passenger safety. The sliding of the first buffer plate 10 drives the first sliding block 11 to slide synchronously along the inner wall of the first slide cylinder 12, compressing the first buffer spring 13, causing the steps to be cushioned when they fall onto the first buffer plate 10, thus protecting the steps and reducing damage. The first buffer plate 10 slides along the sliding plate 6, causing the hydraulic oil in the first channel 14 to push the first gear. Block 16 slides along the first slide groove 15. When the step contacts and presses the first limiting plate 17, the first limiting plate 17 slides along the inner wall of the sliding plate 6 toward the first limiting spring 20. The sliding of the first limiting plate 17 drives the first slider 18 to slide synchronously along the second slide cylinder 19. The first limiting spring 20 is compressed, so that the step pressing the first buffer plate 10 is buffered, thereby protecting the step. The first stop block 16 slides out to limit the step, preventing the step from rebounding and damaging the elevator shaft, thereby reducing maintenance costs.

[0024] The translation mechanism includes a tension spring 28 fixedly connected to the inner wall of the sliding shell 5; a first limiting groove 40 is provided on the inner wall of the sliding plate 6; a first limiting cylinder 27 adapted to the first limiting groove 40 is provided on the inner wall of the sliding shell 5; a first slide rail 29 is provided on the inner wall of the sliding shell 5; a second groove 30 and a hole 31 are provided on the inner wall of the sliding shell 5; a second pushing block 32 adapted to the second groove 30 is provided on the inner wall of the sliding shell 5; a first sliding rod 33 is fixedly connected to the outer wall of the sliding shell 5; a micro-hole 67 adapted to the hole 31 is provided on the inner wall of the first sliding rod 33; and a second sliding block 32 is slidably connected to the outer wall of the first sliding rod 33. The sliding rod 34 has a fixed post 9 fixedly connected to the outer wall of the first fixed plate 2. The fixed post 9 has a fixed post 8 fixedly connected to the outer wall of the second baffle 8. The inner wall of the second baffle 8 has a first channel 35. The inner wall of the fixed post 9 has a second channel 36. The inner wall of the first fixed plate 2 has a second slide rail 39. The outer wall of the sliding shell 5 has a first moving block 38 adapted to the second slide rail 39. The outer wall of the first moving block 38 has a first sliding post 37 adapted to the second channel 36. The first limiting cylinder 27 forms a telescopic structure with the sliding plate 6 through the tension spring 28. The outer wall of the second baffle 8 has a connecting block 70 fixedly connected to it.

[0025] In use, after the step falls onto the first buffer plate 10 and stabilizes, the sliding plate 6 slides along the first slide rail 29 towards the step, causing the first limiting cylinder 27 to slide synchronously along the first limiting groove 40. At this time, the tension spring 28 is stretched to protect the sliding plate 6 from sliding along the inner wall of the sliding shell 5, preventing damage to parts. The sliding plate 6 drives the second push block 32 to slide synchronously along the second groove 30 towards the step. The sliding of the second push block 32 causes the hydraulic oil in the second groove 30 to be squeezed through the hole 31 into the micro-hole 67. The hydraulic oil passes through the first channel 35 in the second baffle 8 and pushes the first sliding column 37 to slide along the second channel 36 in the fixed column 9 towards the first moving block 38. The sliding of the first sliding column 37 drives the first... The moving block 38 slides synchronously along the second slide rail 39, thereby driving the sliding shell 5 to slide synchronously along the outer wall of the first fixed plate 2. The sliding shell 5 drives the sliding plate 6 to slide. At this time, the sliding shell 5 drives the first slide rod 33 to slide along the inner wall of the second slide rod 34 towards the sliding shell 5, so that the sliding shell 5, the sliding plate 6 and the first baffle 7 slide along the second slide rail 39. At this time, the sliding plate 6 slides along the sliding shell 5 towards the step. The sliding plate 6 drives the first baffle 7 to move synchronously, so that one end of the telescopic rod 71 slides along the inner wall of the first baffle 7 and the other end of the telescopic rod 71 slides along the inner wall of the connecting block 70, thereby leaving sufficient space for staff to maintain the elevator, facilitating maintenance and reducing the time spent on disassembly.

[0026] The buffer protection assembly includes a buffer mechanism and a protection mechanism. The buffer mechanism includes a fixing block 3 fixedly connected to the outer wall of the frame 1. A second fixing plate 4 and a support plate 41 are fixedly connected to the outer wall of the fixing block 3. A limit ring 46 is fixedly connected to the inner wall of the support plate 41. A first through hole 47 and a second limit groove 48 are provided on the inner wall of the support plate 41. A second sliding post 49 adapted to the second limit groove 48 is provided on the inner wall of the support plate 41. A second limit is fixedly connected to the outer wall of one end of the second sliding post 49. A fixed shaft 72 is fixedly connected to the inner wall of the support plate 41, and a protrusion 74 is rotatably connected to the outer wall of the fixed shaft 72. A rotating cylinder 73 is fixedly connected to the outer wall of the protrusion 74, and a torsion spring 75 is fixedly connected to the inner wall of the rotating cylinder 73. A second buffer plate 42 is slidably connected to the inner wall of the support plate 41. A guide rail 68 is provided on the inner wall of the support plate 41, and a pressing block 58 adapted to the guide rail 68 is provided on the inner wall of the support plate 41. A receiving shell 59 is installed on the outer wall of the support plate 41. The outer wall of the second buffer plate 42 is provided with a second push column 43 adapted to the guide rail 68. The outer wall of the second buffer plate 42 is provided with a second sliding block 44 adapted to the limiting ring 46. A second buffer spring 45 is fixedly connected to the outer wall of the second buffer plate 42. A limiting baffle 60 is fixedly connected to the outer wall of the support plate 41. A second camera 66 is fixedly connected to the outer wall of the limiting baffle 60. A limiting groove 61 and a second limiting spring 64 are fixedly connected to the inner wall of the limiting baffle 60. The device is dynamically connected to an extrusion plate 62. An extension cylinder 63 adapted to a limiting groove 61 is provided on the outer wall of the extrusion plate 62. The second sliding block 44 forms a telescopic structure with the limiting ring 46 through the second buffer spring 45. The extension cylinder 63 forms a telescopic structure with the limiting groove 61 through the second limiting spring 64. The support plate 41 is fixedly connected to one end of the torsion spring 75. The extrusion block 58 is slidably connected to the support plate 41 through the second extension column 43. The second limiting block 50 is slidably connected to the support plate 41 through the second sliding column 49.

[0027] In use, when passengers ride the elevator to an angled position, the number of passengers increases and the weight increases. If a step detaches from the second fixed plate 4 at this time, a passenger falls and suffers initial injury. The second camera 66 captures the step detachment and transmits the image information to the escalator power control system. The escalator power control system analyzes and processes the signal. After confirming the step detachment, it sends a control signal to trigger the safety relay, shutting off the elevator power to protect passengers and prevent the elevator from continuing to run and causing secondary injury. When the step contacts and presses against the second buffer plate 42, the second buffer plate 42 slides along the inner wall of the support plate 41 towards the limit ring 46. The sliding of the second buffer plate 42 drives the second sliding block 44 to move synchronously along the limit ring 46. The sliding action compresses the second buffer spring 45, cushioning the steps and preventing them from falling and causing damage. A rotating drum 73 and a torsion spring 75 are connected; one end of the torsion spring 75 is fixedly connected to the support plate 41, and the other end is fixedly connected to the rotating drum 73. The torsion spring 75 exerts a lateral opening force, causing the rotating drum 73 to rotate about the axis of the fixed shaft 72. This causes the side of the rotating drum 73 in contact with the second limiting block 50 to press against the second limiting block 50, thus counteracting the weight of the hydraulic oil and preventing the second limiting block 50 from popping out when there is no malfunction. The second sliding block 44 slides along the limiting ring 46, pressing the hydraulic oil in the support plate 41 along the first through hole 47 towards the second limiting groove 48, causing the second sliding column 49 to move along the second limiting groove 48 towards... The second limiting block 50 slides in the direction of the second sliding column 49, which drives the second limiting block 50 to slide synchronously. The sliding of the second limiting block 50 pushes the rotating drum 73. The rotating drum 73 rotates, causing the protrusion 74 to rotate along the inner wall of the support plate 41 about the axis of the fixed shaft 72. The torsion spring 75 is compressed, thereby the second limiting block 50 engages the elevator running shaft, mechanically braking the elevator in the event of a power outage, ensuring passenger safety. Due to the instantaneous impact force generated by the step falling onto the surface of the second buffer plate 42, the second buffer plate 42 slides, thereby driving the second push column 43 to slide rapidly along the guide rail 68 towards the extrusion block 58. This causes the second push column 43 to push the extrusion block 58 out of the guide rail 68, thus extruding the extrusion block 58. When step 58 falls into receiving shell 59, the broken step slides along support plate 41 towards pressing plate 62. Since the weight of the step itself is less than the instantaneous impact force of the falling step, the sliding of the step along support plate 41 prevents the pressing block 58 from being squeezed out of guide rail 68. Simultaneously, hydraulic oil in chamber 76 is pushed towards frame 1 along the second through hole 51 on support plate 41. During maintenance, staff can determine the maintenance location by observing the pressing block 58 in receiving shell 59, reducing unnecessary disassembly and maintenance time. The step slides along the second fixing plate 4 fixed to fixing block 3. When the step contacts and presses the pressing plate 62, the pressing plate 62 slides along limiting baffle 60 towards second limiting spring 64.The sliding of the extrusion plate 62 causes the propulsion cylinder 63 to slide along the limiting groove 61, compressing the second limiting spring 64 and providing buffer protection for the steps, reducing damage to the steps.

[0028] The protective mechanism includes a protective shell 52 installed on the inner wall of the second fixed plate 4. The inner walls of the second fixed plate 4 and the support plate 41 are both provided with second through holes 51. The inner wall of the support plate 41 is provided with a cavity 76. A second moving block 53 is slidably connected to the inner wall of the protective shell 52. A push rod 69 adapted to the second through hole 51 is provided on the outer wall of the second moving block 53. A second stop block 56 is slidably connected to the inner wall of the second moving block 53. A limiting groove 57 is provided on the inner wall of the second stop block 56. A second limiting cylinder 54 adapted to the limiting groove 57 is provided on the inner wall of the second moving block 53. A compression spring 55 is fixedly connected to the inner wall of the second moving block 53. The push rod 69 is slidably connected to the protective shell 52 through the second moving block 53. The second stop block 56 and the second limiting cylinder 54 form a telescopic structure through the compression spring 55.

[0029] In use, the step detaches and contacts and presses against the second buffer plate 42. The second buffer plate 42 slides, causing the second sliding block 44 to slide along the limiting ring 46. At this time, the hydraulic oil in the cavity 76 on the support plate 41 is squeezed and enters the second through hole 51 on the support plate 41. Then, the hydraulic oil passes through the second through hole 51 in the second fixed plate 4 and pushes the push rod 69 to slide along the inner wall of the protective shell 52 towards the second moving block 53. The push rod 69 slides, causing the second moving block 53 to slide synchronously along the inner wall of the protective shell 52. When the step collides with the second buffer plate 42, it rebounds and contacts and presses against the second stop block 56, causing the second stop block 56 to slide along the inner wall of the second moving block 53. The second limiting cylinder 54 slides synchronously along the limiting groove 57. The sliding of the second stop block 56 causes the compression spring 55 to be compressed, thus providing buffer protection for the step and elevator parts.
