Description

Technical Field

[0001] The invention relates to a public transportation type escalator, in particular to a public transportation type escalator capable of preventing a luggage box from rolling down. Background Art

[0002] Public transportation escalators are commonly found in subways, airports, train stations, exhibition centers and other traffic-intensive places. Existing public transportation escalators do not have a fixing device for suitcases. In order to save effort in dragging suitcases, the rollers are designed to have as little friction as possible. As long as there is a slight external force, the suitcases will easily roll and fall and injure pedestrians, posing a safety hazard.

[0003] Although there are a few patented escalator technologies with the function of holding luggage in place in this field, there are the following problems: First, the ultimate effect achieved by this type of escalator is to prevent the luggage from falling further when it falls, but public transportation escalators have a large flow of people, the density of people on the escalator is high, and pedestrians generally do not have a vigilant mentality that may cause danger. At this time, whether the luggage falls one or two steps, it will cause the pedestrians on the next step to fall forward, and may even cause a chain of falls among the crowd; second, it is manually operated, and it is necessary to take the fixing device to tighten the luggage by yourself, while public transportation escalators have a large flow of people and the crowd moves quickly, and manual operation will greatly affect the efficiency of crowd transportation; third, it occupies the original standing space of the escalator, resulting in a decrease in the flow of people that can be transported.

[0024] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, in the description of the present invention, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0025] Reference Figures 1 to 6A public transportation escalator for preventing luggage from rolling down comprises steps, wherein the steps comprise a pedal 1, a kick plate 2, a support frame 3 and a guide wheel, an empty space below the pedal 1 is provided with an installation box 4, a drive controller 5 is provided in the installation box 4, a flattening and sinking mechanism and a sensor component, the pedal 1 is provided with a standing area, a roller fixing area and a foot-stepping sensor area, the roller fixing area is provided with a first opening 101 adapted to the flattening and sinking mechanism, the flattening and sinking mechanism is exposed to the surface of the pedal 1 through the first opening 101, and the sensor component is installed corresponding to the foot-stepping sensor area.

[0026] When the luggage carrier steps on the foot-stepping sensing area, the drive controller 5 receives the signal from the sensor component and controls the movement of the flattening and sinking mechanism, which sinks to form a storage space for the luggage rollers, thereby limiting the rolling of the rollers and preventing the luggage from falling. The foot-stepping sensor design does not require manual operation and does not affect the moving speed of the crowd. All equipment and components are arranged in the vacant space below the pedal 1, so as not to occupy the original standing space of the public transportation escalator and ensure the flow of people.

[0027] The flattening and sinking mechanism includes a rotating power source 6 (stepping motor) and a folding plate 7 with an L-shaped cross section. The lower long side end of the folding plate 7 is rotatably connected to the output end of the rotating power source 6. The rotating power source 6 controls the folding plate 7 to rotate and tilt downward to form a sunken space for accommodating the rollers of the luggage case. The L-shaped structural design of the folding plate 7 is: first, whether it is an upward escalator or a downward escalator, the inclined sunken space design can make the center of gravity of the luggage case as close to the inner side of the step as possible, further reducing the possibility of the luggage case falling; second, to make the top surface of the folding plate 7 smoothly connected with the pedal 1 when it is not tilted; third, to match the installation position of the stepping motor and the position of its output end.

[0028] Considering that if the folding plate 7 is only tilted downward to form an accommodating space, the folding plate 7 will be subjected to a relatively large pressure when the folding plate 7 is flipped upward to reset and simultaneously lifts the roller, and the roller may be stuck between the first opening 101 and the folding plate 7, therefore, the upper long side end of the folding plate 7 is rotatably connected to the first long side end of the pulling plate 8, and the second long side end of the pulling plate 8 is rotatably connected to the pedal 1. The pulling plate 8 assists the folding plate 7 in supporting the roller of the luggage case, and avoids the top of the folding plate 7 from being subjected to excessive force and breaking and deforming as much as possible, and also avoids the roller of the luggage case from being stuck.

[0029] The output end of the rotation power source 6 is provided with a coupling and a first rotating shaft 9, a second rotating shaft 10 is provided between the folding plate 7 and the pulling plate 8 to form a rotation connection, and pulling support rods 11 are provided on both sides of the folding plate 7, and the two ends of the pulling support rod 11 are respectively connected to the first rotating shaft 9 and the second rotating shaft 10 in rotation, and the folding plate 7 and the pulling support rod 11 are both relatively stationary with the first rotating shaft 9. The functions of the pulling support rod 11 are: first, when the folding plate 7 is turned down, it assists in pulling the folding action of the folding plate 7 and the pulling plate 8; second, when the folding plate 7 is not turned over, it serves as a supporting structure to enhance the strength of the folding structure.

[0030] The sensor assembly includes a support column 15 and a sensor 13. The support column 15 is installed inside the installation box 4. A sliding portion is provided on the upper part of the support column 15. The sliding portion is sleeved with a spring 14. The sliding portion is slidably engaged with a pedal board 12. The top of the spring 14 supports the bottom of the pedal board 12. The reason why the structure that triggers the sensor 13 is set as the pedal board 12 in this embodiment is that: first, the pedal area is large enough, and there is no need to search for it specifically when the crowd density is extremely high; second, it is set as the pedal board 1 to facilitate control of it being flush with the pedal 1.

[0031] The drive controller 5 is provided with a delay module. The foot pedal 12 is pressed down to trigger the sensor 13. The drive controller 5 receives the signal and then controls the flattening and sinking mechanism to sink and start the delay module. Since the running speed of the escalator is fixed, the time for each step from the starting point to the end point is also fixed. This time is used as the setting time of the delay module. After the set delay time, the drive controller 5 controls the flattening and sinking mechanism to flatten and reset, and the suitcase carrier can easily and smoothly pull away the suitcase.

[0032] The foot pedal 12 includes a horizontal plate portion 1201 and a connecting portion 1202. The pedal 1 is provided with a second opening 102 adapted to the horizontal plate portion 1201. The horizontal plate portion 1201 is exposed to the surface of the pedal 1 through the second opening 102. The support column 15 is provided with a bracket. The sensor 13 is a photoelectric sensor 13. The bracket is provided with the photoelectric sensor 13. The connecting portion 1202 is provided with a signal sheet 1203. When the horizontal plate portion 1201 is pressed down, the signal sheet 1203 passes through the sensing area of ​​the photoelectric sensor 13, and the photoelectric sensor 13 sends a signal to the drive controller 5. The component design has the advantage of convenient assembly. The sensor component can be assembled as a whole first, and then directly installed in the installation box 4, without first installing the sensor 13 at a certain position of the installation box 4 or the pedal 1, and then installing the support column 15 and other components, and at the same time, it is necessary to specially calibrate whether the signal sheet 1203 passes through the sensing area of ​​the photoelectric sensor 13.

[0033] The top surface of the pedal 1 is provided with an anti-skid pad 17, and the anti-skid pad 17 is provided with a notch corresponding to the roller fixing area, and the anti-skid pad 17 covers a part of the folding plate 7. Figure 5 As shown, the anti-skid pad 17 covering a portion of the folding plate 7 has a certain effect of preventing the roller that has entered the recessed space from escaping.

[0034] The anti-skid pad 17 is provided with anti-skid patterns, and the patterns of the anti-skid pad 17 corresponding to the standing area are different from the patterns corresponding to the foot-stepping sensing area, so as to indicate the position of the foot-stepping sensing area.

[0035] It should be noted that even if a pedestrian who is not carrying a suitcase accidentally steps on the foot-operated sensing area, it will not affect the pedestrian's riding on the escalator, because the lifting stroke of the foot-operated plate 12 is extremely small, and its only purpose is to trigger the photoelectric sensor 13. The lifting difference will basically not affect the pedestrian's standing. The flattening and sinking mechanism is arranged near the inner side of the step, the sinking depth is shallow, and the stepping area is not large, which basically does not affect the pedestrian's standing.

[0036] The anti-skid pad 17 is made of an elastically deformable material, such as rubber, etc. Since the anti-skid pad 17 of this embodiment also has the function of preventing the roller from escaping from the sunken space, the part of the anti-skid pad 17 covering the folding plate 7 is frequently impacted by external forces. The use of an elastically deformable material does not affect the roller-blocking function of the anti-skid pad 17, and at the same time has the advantage of being less prone to deformation than hard materials.

[0037] The top surfaces of the folding plate 7 and the pulling plate 8 are provided with anti-skid strips 17, which not only have an anti-skid effect but also reduce the height difference between the folding plate 7 and the pulling plate 8 and other parts.

[0038] This embodiment also includes other equipment or components such as trusses, guide rails, handrails, and drive devices, which are conventional structural designs in the field and are not the innovation of this embodiment, and are not described in detail here. The above implementation methods cannot limit the protection scope of the invention. The equal modifications and changes made by personnel in the professional and technical field without departing from the overall concept of the invention are still within the scope of the invention.
