Description

Technical Field

[0001] This utility model relates to the field of escalator maintenance technology, specifically to an escalator auxiliary maintenance device. Background Technology

[0002] Escalator maintenance is crucial for ensuring the safe and efficient operation of escalators. It involves multiple aspects such as daily inspections, regular maintenance, and troubleshooting. By cleaning, lubricating, and replacing parts, it reduces equipment wear, extends the escalator's lifespan, and lowers replacement costs.

[0003] The common method for cleaning escalators involves cleaning staff moving up and down the escalator while continuously wiping the sides with cleaning equipment. This method is relatively labor-intensive. A patent (application number: 202020365596.6, titled "An Escalator Auxiliary Maintenance Device") primarily targets the cleaning of glass escalators, significantly reducing labor costs. However, this patent has limitations: its side cleaning structure cannot be extended or adjusted, limiting its application to cleaning glass escalators in shopping malls. Metal escalators used in public environments like subway stations have wider sides, making this structure unsuitable and reducing the overall practicality of the equipment. Furthermore, the scraping method used for cleaning also limits its cleaning capabilities. Utility Model Content

[0004] The purpose of this invention is to provide an escalator auxiliary maintenance device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fixed frame is included, telescopic frames are installed on both sides of the fixed frame, a fixed plate is installed at the bottom of the telescopic frame, a triangular plate is fixed at the bottom of the fixed plate, a side frame is fixed inside the triangular plate, the side frame has an open structure inside and a central rotating shaft is rotatably connected inside, a soft brush roller is fixed on the central rotating shaft, and a side wheel is fixed at the upper end of the central rotating shaft.

[0006] Preferably, a telescopic plate is fixed to one side of the telescopic frame, and a slot is provided on the side wall of the fixed frame at a position corresponding to the telescopic plate.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: it includes a fixed frame 1, telescopic frames 2 installed on both sides of the fixed frame 1, a fixed plate 3 installed at the bottom of the telescopic frame 2, a triangular plate 4 fixed at the bottom of the fixed plate 3, a side frame 5 fixed inside the triangular plate 4, the side frame 5 has an open structure inside and is rotatably connected to a central rotating shaft 52, a soft brush roller 53 fixed on the central rotating shaft 52, a side wheel 51 fixed at the upper end of the central rotating shaft 52, an installation groove 23 opened at the bottom of the telescopic frame 2, the upper end of the fixed plate 3 inserted into the installation groove 23, a side locking bolt 6 for locking the fixed plate 3 is provided on the outside of the telescopic frame 2, a fixed groove 11 is installed at the bottom of the fixed frame 1, and an anti-slip pad is provided in the fixed groove 11.

[0019] A telescopic plate 22 is fixed to one side of the telescopic frame 2. A slot is provided on the side wall of the fixed frame 1 at a position corresponding to the telescopic plate 22. The end of the telescopic plate 22 is slidably connected to the slot. A top locking bolt 7 is provided at the upper end of the fixed frame 1 to lock the telescopic plate 22. A guide block is fixed to the outside of the fixed frame 1. A limiting frame 21 adapted to the guide block is fixed to the outside of the telescopic frame 2. The limiting frame 21 is slidably connected to the guide block. The telescopic plate 22 is located in the fixed frame 1 with its upper and lower parts staggered. The top locking bolt 7 is located on the upper end of the fixed frame 1 near the slot opening. The guide block is located on the side wall of the fixed frame 1 with its upper and lower parts distributed. The telescopic plate 22 is pulled to slide in the slot, realizing the telescopic extension and retraction of the telescopic frame 2. After the extension and retraction reaches the designated position, the top locking bolt 7 is used to fix the telescopic plate 22 and the telescopic frame 2.

[0020] The central rotating shaft 52 is divided into upper and lower sections, and the bottom bevel gear 54 and the end bevel gear 55 are fixed at the connection of the upper and lower sections respectively. A transmission bevel gear 56 is rotatably connected inside the side frame 5 and between the bottom bevel gear 54 and the end bevel gear 55. The transmission bevel gear 56 meshes with the bottom bevel gear 54 and the end bevel gear 55.

[0021] Working principle: First, the fixing plate 3 is inserted into the mounting slot 23 and locked in place using the side locking bolts 6. This fixes the side frame 5 to both sides of the bottom of the fixing frame 1. Then, the fixing frame 1 is installed onto the escalator handrail, so that the handrail is inserted into the fixing slot 11. By pressing down by hand, the fixing frame 1 and the handrail move synchronously. The distance between the side frame 5 and the escalator side wall can be adjusted by the telescopic adjustment of the telescopic frame 2, ensuring that the side wheel 51 abuts against the escalator side wall. Therefore, when the fixing frame 1 and the handrail slide synchronously, the transmission of the side wheel 51 can drive the central rotating shaft 52. The rotation drives the soft brush roller 53 to rotate, wiping the side wall of the escalator. During this process, the transmission of the bottom bevel gear 54, the end bevel gear 55 and the drive bevel gear 56 makes the upper and lower sections of the central rotating shaft 52 rotate in opposite directions, preventing the soft brush roller 53 from rolling on the side wall of the escalator and losing its wiping effect. This allows for better rotation and wiping, ensuring better cleaning. At the same time, by extending and retracting the telescopic frame 2, the distance between the two side frames 5 can be changed, allowing for wiping of narrower glass escalators as well as wider metal escalators, improving the practicality of the equipment.
