Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a protection device for the pedal of an escalator walkway. Background Art

[0002] An escalator walkway, also known as a moving sidewalk or an autowalk, is a conveying device used to help people move smoothly over a short horizontal or inclined distance. It is similar to an escalator but is usually horizontal or has only a slight inclination for gently conveying pedestrians. It is widely used in shopping malls, shopping centers, public transportation stations, exhibition centers, conference venues and other places.

[0003] When the existing escalator walkway is in use, its principle is similar to that of the conveyor belt of an assembly line. The difference is that the conveyor belt is replaced by a metal pedal to improve the heavy load bearing capacity of the escalator walkway by using the metal pedal.

[0004] Since the internal structure of the escalator walkway is relatively complex, an anti-detachment design is installed inside it. However, during long-term use of the metal pedal, frequent support of heavy objects will cause the pedal to sink and deform. At this time, the pedal does not fall off, so the escalator walkway will not stop, which will bring potential safety hazards to the use of the escalator walkway. Therefore, a protection device for the pedal of an escalator walkway is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a protection device for the pedal of an escalator walkway, aiming to improve the problem in the existing technology that the anti-detachment design of the escalator walkway will not stop the escalator walkway when the pedal sinks and deforms, thus leading to potential safety hazards.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a protection device for the pedal of an escalator walkway, including a pedal. One side below the pedal is provided with a side plate, and both the side plate and the pedal are installed in the pit for installing the escalator. One side of the side plate is fixedly connected with a support plate. The middle of the support plate is fixedly connected with a sleeve. A top rod is slidably connected to the inner top of the sleeve. The top of the top rod is fixedly connected with a support. The middle of the support is rotatably connected with a roller. The top of the roller is in contact with the bottom surface of the pedal. A spring is arranged at the bottom of the top rod, and the spring is at the inner bottom of the sleeve. One side in the middle of the outer wall of the top rod is fixedly connected with a side rod. The top and bottom of one side of the side rod are fixedly connected with top blocks. A support frame is arranged below the pedal. The top and bottom of the inner wall of the support frame are fixedly connected with contact switches, and the central axes of the top blocks and the contact switches coincide. A support component for supporting the support plate is installed on one side of the side plate.

[0007] As a further description of the above technical solution:

[0008] The support assembly includes a clamping frame. A bolt is threadedly connected to the top of the clamping frame, and a nut is threadedly connected to the bottom of the bolt, and the nut is located at the bottom of the clamping frame. The outer wall of the support plate is in the middle of the clamping frame, and the bolt penetrates through the support plate.

[0009] As a further description of the above technical solution:

[0010] A chute is provided in the middle of the sleeve, and the bottom of the ejector rod and the spring are both located in the chute.

[0011] As a further description of the above technical solution:

[0012] A limiting plate is fixedly connected to the bottom of the ejector rod, and the outer wall of the limiting plate is slidably connected to the inside of the chute.

[0013] As a further description of the above technical solution:

[0014] A clamping groove is provided in the middle of the clamping frame, and the outer wall of the support plate is in contact with the inner wall of the clamping groove.

[0015] As a further description of the above technical solution:

[0016] A plurality of grooves are provided on the outer wall of the pedal, and the roller is in contact with the inner wall of the groove.

[0017] As a further description of the above technical solution:

[0018] The support frame is arranged in a horizontal concave shape, and the side rod is located on the open side of the support frame.

[0019] As a further description of the above technical solution:

[0020] A plurality of top blocks are provided. A plurality of touch switches are fixedly connected to the top surface and the bottom surface of the inner wall of the support frame. A controller is fixedly connected to one side of the outer wall of the support frame.

[0032] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the specification of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1-6, an embodiment provided by the present utility model: an automatic sidewalk pedal protection device, including a pedal 1, a side plate 2 is arranged on one side below the pedal 1, and both the side plate 2 and the pedal 1 are installed in the pit for installing the escalator. A support plate 3 is fixedly connected to one side of the side plate 2, a sleeve 4 is fixedly connected to the middle of the support plate 3, a top rod 5 is slidably connected to the inner top of the sleeve 4, a support 8 is fixedly connected to the top of the top rod 5, a roller 9 is rotatably connected to the middle of the support 8, and the top of the roller 9 is in contact with the bottom surface of the pedal 1. A spring 7 is arranged at the bottom of the top rod 5, and the spring 7 is located at the inner bottom of the sleeve 4. A side rod 10 is fixedly connected to one side of the middle of the outer wall of the top rod 5, and top blocks 11 are fixedly connected to the top surface and the bottom surface of one side of the side rod 10. A support frame 12 is arranged below the pedal 1, and contact switches 13 are fixedly connected to the top surface and the bottom surface of the inner wall of the support frame 12, and the central axes of the top blocks 11 and the contact switches 13 coincide. A support component for supporting the support plate 3 is installed on one side of the side plate 2.

[0034] During use, after the installation of the automatic sidewalk is completed, the power cord of the power component of the automatic sidewalk is connected to the outgoing line switch at this time. When the pedal 1 contacts the roller 9, the pedal 1 will squeeze the roller 9, thereby compressing the spring 7 and making the side rod 10 located in the middle of the clamping frame 15. When there are protrusions or depressions on the pedal 1, the protrusion position will further press the roller 9 at this time, thereby driving the top rod 5 and the side rod 10 to move downward, so that the top block 11 at the bottom of the top rod 5 contacts the contact switch 13 at the inner bottom of the clamping frame 15, while the depression position will not compress the roller 9. At this time, the spring 7 can push out the top rod 5, and the top rod 5 will drive the side rod 10 to move upward. At this time, the top block 11 at the top of the side rod 10 will contact the contact switch 13 at the inner top of the clamping frame 15; when the top block 11 contacts the contact switch 13, the contact switch 13 can make the power cord in an open circuit state at this time, thereby stopping the power supply of the power cord to the power component of the automatic sidewalk, so that the automatic sidewalk can stop running after the pedal 1 is deformed, thereby improving the use safety of the automatic sidewalk.

[0035] Refer to Figure 1 and Figure 4 , the support component includes a clamping frame 15, a bolt 16 is threadedly connected to the top of the clamping frame 15, a nut 17 is threadedly connected to the bottom of the bolt 16, and the nut 17 is located at the bottom of the clamping frame 15. The outer wall of the support plate 3 is located in the middle of the clamping frame 15, and the bolt 16 passes through the support plate 3. A slot 18 is opened in the middle of the clamping frame 15, and the outer wall of the support plate 3 is in contact with the inner wall of the slot 18.

[0036] When the pedal 1 is deformed and causes the moving walkway to stop running, since the moving walkway will stop when the roller 9 contacts the deformed position of the pedal 1, the deformed position can be stopped at the roller 9. Therefore, during maintenance, the deformed pedal 1 can be quickly determined, thus eliminating the troubleshooting process and improving the efficiency of repairing and replacing the pedal 1. And after removing the bolt 16 and the nut 17, the pull-out support plate 3 can be separated from the side plate 2 at this time, and the roller 9 and the side rod 10 can be removed together. At this time, the blocking of the roller 9 on the deformed pedal 1 can be cancelled, which is beneficial to removing the deformed pedal 1. When the replacement of the pedal 1 is completed, the support plate 3 is inserted into the card slot 18 on the card frame 15 at this time, and finally the bolt 16 is installed to complete the loading and unloading of the support plate 3, which is beneficial to the later loading and unloading of the support plate 3 and the pedal 1.

[0037] Refer to Figure 1 、 Figure 5 and Figure 6 , a chute 19 is provided in the middle of the sleeve 4, and the bottom of the ejector rod 5 and the spring 7 are both located in the chute 19. The bottom of the ejector rod 5 is fixedly connected with a limit plate 6, and the outer wall of the limit plate 6 is slidably connected to the inside of the chute 19.

[0038] The chute 19 can provide an installation space for the spring 7 and the ejector rod 5, and the limit plate 6 can prevent the ejector rod 5 from separating from the sleeve 4.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , a plurality of grooves are provided on the outer wall of the pedal 1, and the roller 9 is in contact with the inner wall of the groove. The support frame 12 is arranged in a horizontal concave shape, and the side rod 10 is located on the opening side of the support frame 12. A plurality of top blocks 11 and rollers 9 are provided. The top surface and the bottom surface of the inner wall of the support frame 12 are fixedly connected with a plurality of contact switches 13, and one side of the outer wall of the support frame 12 is fixedly connected with a controller 14. The contact switches 13 are electrically connected to the controller 14, and the controller 14 is electrically connected to the power assembly for driving the pedal 1 to operate.

[0040] By pressing the roller 9 against the groove on the pedal 1, the phenomenon that the roller 9 is misaligned during rolling can be avoided, so the phenomenon that the contact switch 13 gives a false alarm and causes the moving walkway to stop by mistake can be avoided. By providing a plurality of contact switches, top blocks 11 and rollers 9, the contact points between the roller 9 and the pedal 1 can be increased, so multi-point detection of the pedal 1 can be realized, and the safety hazard caused by the deformation of some positions not being detected can be avoided.

[0041] Working principle: When in use, first install the moving walkway in the pit, and fix the clamping frame 15 and the side plate 2 to the inner bottom of the moving walkway. At the same time, electrically connect the power component used by the moving walkway to the controller 14, and connect the power cord of the power component to the contact switch 13. When power enters the power component, the moving walkway can operate. At this time, the spring 7 can push out the ejector rod 5, so that the roller 9 presses tightly on the pedal 1. When there is a depression on the surface of the pedal 1, the depression will not squeeze the roller 9 at this time. At this time, the spring 7 can push out the ejector rod 5. At this time, the ejector rod 5 will drive the side rod 10 to move upward, and finally make the ejector block 11 on the top surface of the side rod 10 squeeze the contact switch 13 on the inner top of the clamping frame 15. At this time, the contact switch can make the power cord in an open circuit state. Therefore, the power supply to the power component of the moving walkway can be stopped, and at this time, the moving walkway can be stopped from operating. When there is a protrusion on the pedal 1, at this time, the pedal 1 will squeeze the roller 9 to drive the ejector rod 5 into the sleeve 4. At this time, the ejector rod 5 will drive the side rod 10 to move downward, and the ejector block 11 at the bottom of the side rod 10 can squeeze the contact switch 13 on the inner bottom of the clamping frame 15. At this time, the outgoing line switch makes the power cord in an open circuit state to stop the moving walkway from operating. At this time, the contact switch 13 can transmit a signal to the controller 14, and the controller 14 can also interrupt the power component to stop the moving walkway from operating. Therefore, the moving walkway can be stopped when the pedal 1 is deformed, and the moving walkway can be stopped when the roller 9 contacts the deformed position of the pedal 1. Therefore, the deformed position is at the roller 9. At this time, the pedal 1 at the corresponding position can be repaired and replaced. Therefore, it is beneficial to find the fault position in the later stage.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
