Description

Technical Field

[0001] This utility model relates to the field of escalator technology, specifically an anti-deviation guide mechanism for escalator handrails. Background Technology

[0002] An escalator is a public transportation facility that is electrically driven and uses continuous steps as a transport carrier, circulating along a specific inclined track. It is commonly found in places with high traffic such as shopping malls, stations, and airports. It can automatically and continuously carry passengers up and down between different floors, and has the characteristics of efficient and convenient transportation of large numbers of people, effectively improving the efficiency of people's vertical movement within buildings. In order for the escalator handrail to move in a predetermined direction, an escalator handrail guiding mechanism is required.

[0003] An investigation revealed that a Chinese utility model patent (CN218024894U) discloses an automatic cleaning device for escalator handrails. The device includes a frame, a wiping belt conveyor and guide mechanism, and a handrail wiping mechanism. The handrail wiping mechanism comprises a base, a sliding seat, a left clamping arm, and a right clamping arm. The sliding seat is slidably connected to the base, which has a drive mechanism. The left and right clamping arms are slidably connected to the sliding seat. A first guide mechanism is provided between the left clamping arm and the base, and a second guide mechanism is provided between the right clamping arm and the base. The left clamping arm has a left elastic pressure block that conforms to the surface of the escalator handrail, and the right clamping arm has a right elastic pressure block that conforms to the surface of the escalator handrail. When the handrail wiping mechanism clamps the wiping belt to clean the escalator handrail, the combined movement of the left and right clamping arms unfolds the wiping belt and tightly adheres to the surface of the escalator handrail, preventing wrinkles in the wiping belt, avoiding cleaning dead spots, and improving the cleaning effect.

[0004] The aforementioned patents are not very convenient for users to use, and cannot provide a good anti-deviation effect for escalator handrails. This increases the likelihood of handrails derailing during operation, increases the probability of safety accidents, enhances the overall danger of escalators, affects normal operation during subsequent use, increases subsequent maintenance costs, and is detrimental to the long-term use of escalator handrail guide mechanisms.

[0005] Therefore, this utility model provides an anti-deviation guide mechanism for escalator handrails to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides a technical solution: an anti-deviation guide mechanism for escalator handrails, comprising a lower support frame 1, a clamping frame 2 fixedly connected to the top of the lower support frame 1, a fixing plate 3 fixedly connected to one side of the clamping frame 2, a glass handrail 4 fixedly connected to one side of the fixing plate 3, a movable handrail belt 5 movably connected to the top of the glass handrail 4, an extension plate 6 fixedly connected to one side of the lower support frame 1, a deviation detection device 7 fixedly connected to the top of the extension plate 6, a side frame 8 fixedly connected to the top of the lower support frame 1, and a side motor 9 fixedly connected to one side of the side frame 8.

[0029] The output shaft of the side motor 9 is fixedly connected to a rotating threaded column 10 via a coupling. A movable block 11 is movably connected to the outer wall of the rotating threaded column 10. A limit column 12 is movably connected to one side of the movable block 11. A linkage curved block 13 is fixedly connected to one side of the movable block 11. A guide plate 14 is fixedly connected to the bottom of the linkage curved block 13. A guide shaft 15 is fixedly connected inside the guide plate 14. A bearing 16 is fixedly connected to the outer wall of the guide shaft 15. This makes the escalator handrail guide mechanism more convenient to use and effectively provides a good anti-deviation effect for the escalator handrail, thereby reducing the phenomenon of handrail derailment during operation, reducing the probability of safety accidents, reducing the overall danger of the escalator, reducing the maintenance cost in subsequent work, and facilitating the long-term use of the escalator handrail guide mechanism.

[0030] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: an electric push rod 17 is fixedly connected inside the lower support frame 1, and the maximum height of the electric push rod 17 is less than the height of the lower support frame 1, so that the connecting parts of the electric push rod 17 can be quickly adjusted in position. A dust cleaning frame 18 is fixedly connected to the top of the electric push rod 17, and a dust cleaning motor 19 is fixedly connected to one side of the dust cleaning frame 18. The output shaft of the dust cleaning motor 19 is fixedly connected to a dust cleaning roller brush 20 through a coupling, which can perform dust cleaning treatment on the surface of the movable handrail belt 5.

[0031] The outer wall of the limiting column 12 is movably connected to one side of the movable block 11, and the length of the movable block 11 is equal to the length of the rotating threaded column 10, which allows the movable block 11 to move linearly with stability. The interior of the guide plate 14 is fixedly connected to the outer wall of the guide shaft 15, and there are six guide shafts 15, which can orient the position of the movable handrail belt 5. The inner wall of the bearing 16 is fixedly connected to the outer wall of the guide shaft 15, and the outer wall of the bearing 16 is movably connected to one side of the movable handrail belt 5, which reduces the friction with the movable handrail belt 5 during orientation.

[0032] like Figure 1-5 As shown, when a user needs to use an escalator handrail anti-deviation guide mechanism, when the movable handrail 5 moves on the outer wall of the glass handrail 4, the limiting of multiple guide shafts 15 and bearings 16 enables the movable handrail 5 to achieve a guiding effect. If the deviation detection device 7 detects a deviation in the transmission position of the movable handrail 5 during operation, the side motor 9 starts to work. The output shaft of the side motor 9 rotates, causing the rotating threaded column 10 to rotate. At this time, the movable block 11 will move. The movement of the movable block 11 drives the linkage block 13, guide plate 14, guide shaft 15 and bearing 16 to change position, thereby completing the correction of the position of the movable handrail 5. If the surface of the movable handrail 5 needs to be cleaned, the electric push rod 17 extends. The extension of the electric push rod 17 causes the cleaning roller brush 20 to contact the surface of the movable handrail 5. At the same time, the cleaning motor 19 will also work to make the cleaning roller brush 20 rotate to complete the brushing of the movable handrail 5.
