Description

Technical Field

[0001] This utility model relates to an elevator inspection guardrail, belonging to the field of elevator inspection technology. Background Technology

[0002] Elevator maintenance barriers are protective devices used during elevator maintenance. Temporary barriers (usually ≥1.2 meters high) must be erected around the work area during elevator maintenance, and "No Entry" or "Under Maintenance" warning signs must be displayed to prevent personnel from accidentally entering dangerous areas. The barriers must be sturdy and reliable; movable metal barriers are recommended. The barriers should be installed before maintenance begins, covering dangerous areas such as elevator shaft openings and landing doors. After maintenance, all tools must be confirmed to have been removed before the barriers can be removed and elevator operation resumed. If maintenance is carried out in a public area, additional personnel must be on duty or multiple isolation zones must be set up. When maintaining escalators, the barriers should simultaneously block the upper and lower entrances and the area around the maintenance cover.

[0003] Elevator inspection railings are temporary devices placed at elevator entrances to prevent unauthorized personnel from entering during maintenance. Due to varying elevator widths, the length of these railings is often insufficient to effectively protect the elevator entrance, making it difficult to adjust them appropriately and reducing their protective performance. Furthermore, the railings are not easily secured after placement, making them susceptible to being knocked over and losing their protective function, thus affecting their usability. Additionally, existing railings are bulky and difficult to store and preserve after use. Utility Model Content

[0026] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0027] like Figure 1-4 As shown, the elevator maintenance guardrail includes:

[0028] A protective plate 1 is provided, with a sleeve 2 fixedly installed on its side wall. A guide rod 4 is movably sleeved inside the sleeve 2. The guide rod 4 is fixedly connected to a baffle 6 via a pull rod 5. The baffle 6 is in close contact with the back of the protective plate 1. Both the baffle 6 and the side wall of the protective plate 1 are equipped with connecting seats 9. The connecting seats 9 are rotatably connected to the end of a support rod 10. The side wall of the protective plate 1 is provided with a first limiting plate 14, which is in close contact with the surface of the protective plate 1. The side wall of the baffle 6 is provided with a second limiting plate 17, which is in close contact with the surface of the baffle 6. Both the first limiting plate 14 and the second limiting plate 17 are located above the support rod 10.

[0029] The protective plate 1 has two sleeves 2 arranged vertically on its back. Each sleeve 2 has a guide rod 4 slidably connected inside, and the surface of the sleeve 2 has evenly distributed slots 3. The baffle 6 is arranged between the two sleeves 2. The side end of the baffle 6 is fixedly connected to the connecting block 7. The connecting block 7 is threadedly connected to the screw 8 inside, and the end of the screw 8 is distributed correspondingly to the slots 3. The connecting seat 9 is threadedly connected to the bolt 12 inside. The end of the support rod 10 has multiple positioning holes 11 arranged in a circle, and the bolt 12 is distributed correspondingly to the positioning holes 11.

[0030] In this technical solution, the movement of the pull rod 5 and the baffle 6 is achieved by the cooperation of the sleeve 2 and the guide rod 4. When the width of the protective plate 1 is less than the width of the maintenance elevator, the baffle 6 is moved out by pulling the pull rod 5 for width adjustment. After the adjustment is completed, the screw 8 on the connecting block 7 is tightened to move it into the slot 3, thereby achieving locking and fixing of the protective plate 1 and the baffle 6 after relative movement.

[0031] Furthermore, after moving and fixing the baffle 6, rotate the support rod 10 so that it is tilted and set at the bottom of the protective plate 1 and the baffle 6. At this time, tighten the bolt 12 to move it into the corresponding positioning hole 11. At this time, the support rod 10 is limited so that a certain angle is formed between the protective plate 1 and the support rod 10. At this time, the support rod 10 is supported on the ground so that the protective plate 1 and the baffle 6 overlap at the edge of the elevator entrance.

[0032] Two fixing blocks 13 are fixedly connected to the side wall of the protective plate 1. The two fixing blocks 13 are symmetrically arranged on both sides of the first limiting plate 14. The lower fixing block 13 has a U-shaped cross-section. The end of the first limiting plate 14 is fixedly connected to the connecting rod 15. The connecting rod 15 is inserted through the two fixing blocks 13. The width of the first limiting plate 14 is smaller than the width of the groove opened in the lower fixing block 13. A magnet 16 is embedded in the end of the first limiting plate 14, and the magnet 16 is attracted and adhered to the surface of the protective plate 1.

[0033] In this technical solution, when the first limiting plate 14 is rotated, the first limiting plate 14 causes the connecting rod 15 to rotate within the fixed block 13. When the first limiting plate 14 is perpendicular to the protective plate 1, the first limiting plate 14 moves down into the groove of the fixed block 13, thus limiting the first limiting plate 14 and attaching it to one side wall of the elevator entrance.

[0034] The second limiting plate 17 is rotatably connected to the surface of the baffle 6, and the side end of the second limiting plate 17 is connected to the baffle 6 through a torsion spring 18; a number of evenly distributed suction cups 19 are fixedly connected to the side walls of the first limiting plate 14 and the second limiting plate 17, and the second limiting plate 17 is correspondingly arranged on one side of the first limiting plate 14; a rotating rod 20 is rotatably connected to the surface of the baffle 6, and one end of the rotating rod 20 is in contact with the second limiting plate 17.

[0035] In this technical solution, rotating the rotating rod 20 causes the torsion spring 18 to drive the second limiting plate 17 to rotate and contact the other side wall of the elevator entrance. It is then fixed by suction cup 19 adhering to both side walls of the elevator entrance, ensuring that the maintenance railing does not tip over during use. After use, the first limiting plate 14 can be adsorbed by the magnet 16 and stored. The second limiting plate 17 is rotated and restricted by the rotating rod 20, thus achieving storage and facilitating preservation after use.

[0036] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
