Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator landing door anti-falling object device. Background Technology

[0002] Elevator landing doors, also known as elevator hall doors, are door structures installed at the entrances and exits of each floor in the elevator shaft. They are key separating components between the elevator and the floor waiting area. They do not move synchronously with the elevator car, but are fixed at the elevator door on each floor. They only open in conjunction with the car door when the elevator car precisely stops at that floor, allowing passengers or goods to enter or exit. After the elevator car leaves, the landing door automatically closes, sealing the elevator shaft opening and forming a safety barrier.

[0003] An investigation revealed that a Chinese utility model patent, CN216763994U, discloses an elevator landing door anti-falling object safety system. This system includes a frame, guide rail, door hanger, door lock moving hook, door lock hook, and contact switch. The guide rail is mounted on the frame. Rollers are rotatably connected to the door hanger, engaging with the guide rail. The door lock hook and contact switch are fixed to the frame. The door lock moving hook is mounted on the door hanger. The contact switch has a protective shell with through holes corresponding to the contact points of the switch. The door lock moving hook has a door lock pin that is linked to it. The door hanger has an upper retaining hook and a lower retaining hook, extending from the door hanger and respectively surrounding the upper and lower sides of the guide rail. This utility model's elevator landing door anti-falling object safety system, through the protective shell and two retaining hook structures, ensures that the door hanger can effectively open and close during daily use, maintenance, and in the event of an accident, thereby ensuring the stable and safe operation of the elevator.

[0004] When used by users, the aforementioned patents have a single protective structure that is difficult to provide complete protection. They are mostly simple, single barriers that cannot fully cover the gaps and edges of the doors, leaving a lot of gaps. This makes it easy for small items and debris to fall through the gaps in the doors, thus failing to achieve effective multi-layer protection.

[0005] Therefore, there is a particular need for an elevator landing door anti-falling object device. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an elevator landing door anti-falling object device, including a device body 1, an mounting plate 2 fixedly connected to the side surface of the device body 1, and an anti-falling protection mechanism 3 installed on the side surface of the device body 1;

[0028] The fall protection mechanism 3 includes a limiting shaft 301, which is mounted on the main body 1. A snap-fit ​​baffle 302 is fixedly connected to the outer ring surface of the limiting shaft 301. A snap-fit ​​insertion shaft 303 is fixedly connected to one side of the snap-fit ​​baffle 302. A mating cylindrical insertion rod 306 is fixedly connected to one side of the main body 1. A mating collar 308 is fitted onto the outer ring surface of the mating cylindrical insertion rod 306. An upper fixing plate 305 is inserted into the side surface of the snap-fit ​​insertion shaft 303. One side of the upper fixing plate 305 is fixed... A docking collar 308 is fixedly connected to one side of the upper fixing plate 305, a docking plate 309 is fixedly connected to one side of the upper fixing plate 305, a first telescopic rod 310 is fixedly connected to the bottom surface of the docking plate 309, an anti-fall mounting base plate assembly 311 is fixedly connected to the bottom surface of the first telescopic rod 310, a limit guide plate 313 is fixedly connected to the bottom surface of the anti-fall mounting base plate assembly 311, a second telescopic rod 316 is fixedly connected to one side of the limit guide plate 313, and a reinforcing plate 317 is fixedly connected to one side of the second telescopic rod 316.

[0029] Furthermore, the precise matching structure of the snap-fit ​​opening 304 and the snap-fit ​​shaft 303 can solve the problems of easy misalignment of components and low assembly efficiency in the prior art. Moreover, this matching structure does not require additional calibration, which not only improves the assembly efficiency, but also prevents the upper fixed plate 305 from lateral displacement during elevator vibration through the tight fit, thus laying the foundation for the upper stability of the anti-fall protection mechanism 3.

[0030] Furthermore, the inner surface of the docking collar 308 is provided with a docking socket 307, and the docking socket 307 and the docking cylindrical plug 306 are structurally matched. The matching docking structure can make up for the defects of large gaps and poor stability in the component connection in the prior art. The complete matching of the docking socket 307 and the docking cylindrical plug 306 can eliminate the connection gap. At the same time, it forms a double fixation with the snap-fit ​​plug shaft 303, distributing the force of the upper fixing plate 305 to the docking collar 308 and the snap-fit ​​baffle 302, avoiding overload of a single connection point, and further enhancing the connection reliability between the upper fixing plate 305 and the device body 1.

[0031] Furthermore, a movable limiting ring 312 is fixedly connected to the upper surface of the anti-fall mounting base plate assembly 311, and the movable limiting ring 312 and the docking plate 309 are matched in size. The matching structure between the movable limiting ring 312 and the docking plate 309 can solve the problem of easy shaking and insufficient stability of the protective components after height adjustment in the prior art.

[0032] Furthermore, limiting insertion plates 315 are inserted into both sides of the limiting guide plate 313, and the limiting insertion plates 315 and the limiting guide plate 313 are connected. The insertion structure of the limiting insertion plates 315 and the limiting guide plate 313 can solve the problem in the prior art that the coverage range of the limiting guide plate 313 is fixed and cannot be adapted to different width doors. The insertion depth of the limiting insertion plates 315 can be flexibly adjusted according to the width of the door, extending the lateral coverage range of the limiting guide plate 313. At the same time, the insertion structure can enhance the overall rigidity of the limiting guide plate 313, prevent the guide plate from bending due to the increase in span, and ensure the stable support effect of the limiting guide plate 313 on the second telescopic rod 316 and the protective plate.

[0033] Furthermore, the side surface of the limiting guide plate 313 is provided with a guiding opening 314, and the size of the guiding opening 314 and the limiting plug-in plate 315 are matched. The matching structure between the guiding opening 314 and the limiting plug-in plate 315 can solve the problems of difficult disassembly and assembly and low maintenance efficiency of the limiting plug-in plate 315 in the prior art. Its guiding opening 314 can provide precise insertion guidance for the limiting plug-in plate 315, making the insertion and removal process smoother. Disassembly and assembly can be completed quickly without the aid of tools, which not only simplifies the maintenance process, but also reduces component wear. At the same time, the tight size match can prevent the limiting plug-in plate 315 from falling out on its own during use, ensuring structural stability.

[0034] Furthermore, the reinforcing plate 317 is connected to the limiting guide plate 313 via the second telescopic rod 316, and the reinforcing plate 317 is symmetrically arranged with the vertical center line of the elevator protective plate 318 preventing the landing door from falling as the axis of symmetry. The symmetrical reinforcing plate 317 structure can solve the problems of uneven stress and easy deformation of the protective plate in the prior art. The symmetrically arranged reinforcing plate 317 can evenly transfer the stress of the protective plate to the second telescopic rods 316 on both sides, avoiding deformation of the protective plate due to excessive local stress. At the same time, the symmetrical structure can ensure that the protective plate always remains horizontal when adjusted laterally, preventing new gaps from being generated due to tilting, and ensuring complete coverage of the landing door gap.

[0035] Furthermore, the upper surface of the mounting plate 2 is provided with multiple mounting openings 4. The multiple mounting openings 4 can solve the problems of single-point fixing and easy loosening due to vibration in the prior art. Multiple mounting openings 4 can achieve multi-point fixing, distributing the weight and force of the main body 1 of the device to multiple points, enhancing the connection between the device and the door frame. At the same time, it can adapt to the fixing hole distribution of different specifications of door frames, eliminating the need for additional on-site drilling, further simplifying the installation process, and avoiding the risk of device falling off due to single-point fixing failure.

[0036] Furthermore, a fall-prevention elevator protection plate 318 is fixedly connected to one side of the reinforcing plate 317, and the fall-prevention elevator protection plate 318 is connected to the second telescopic rod 316 through the reinforcing plate 317. The reinforcing plate 317 can solve the problem of easy breakage and protection failure of the protection plate in the prior art when the protection plate is directly connected. The reinforcing plate 317 can increase the connection area between the protection plate and the second telescopic rod 316, and evenly transfer the impact force borne by the protection plate to the telescopic rod. At the same time, the rigid structure of the reinforcing plate 317 itself can support the protection plate to keep it flat, and prevent the protection plate from deforming due to long-term obstruction of debris or collision, so as to ensure that the protection effect is always stable.

[0037] Furthermore, the reinforcing plate 317 is connected to the limiting guide plate 313 via the second telescopic rod 316, and there are multiple second telescopic rods 316. The multiple second telescopic rods 316 structure can solve the problems of single-point control and easy tilting of the protective plate in the prior art.

[0038] Working principle: When a user needs to use an elevator landing door anti-falling object device, the operator first aligns the main body 1 of the device with the preset installation position of the elevator landing door. The initial positioning is achieved by fixing the mounting plate 2 to the side surface of the main body 1. Using the mounting opening 4 through the upper surface of the mounting plate 2, bolts and other fasteners are inserted and tightened to firmly fix the main body 1 to the elevator landing door frame, thus completing the installation foundation of the main body 1. Take the upper fixing plate 305 in the anti-falling protection mechanism 3, align the snap-fit ​​opening 304 on its side surface with the snap-fit ​​insertion shaft 303 on the side of the snap-fit ​​baffle 302 connected by the limiting shaft 301 on the main body 1, and insert it to complete the initial docking between the upper fixing plate 305 and the snap-fit ​​baffle 302.

[0039] Synchronously adjust the docking collar 308 fixedly connected to one side of the upper fixed plate 305, so that the docking socket 307 on the inner ring surface of the docking collar 308 is precisely aligned with the docking cylindrical plug 306 fixedly connected to one side of the device body 1. Fit the docking collar 308 into the docking cylindrical plug 306 and lock it in place, so as to achieve double fixation of the upper fixed plate 305 and the device body 1, and complete the upper assembly of the anti-fall protection mechanism 3. Using the docking plate 309 fixedly connected to one side of the upper fixed plate 305, extend the first telescopic rod 310 fixedly connected to the bottom surface of the docking plate 309 downward, so that the anti-fall mounting base plate assembly 311 connected to the bottom of the first telescopic rod 310 is moved to the preset height. Adjust the movable limiting plug 312 fixedly connected to the upper surface of the anti-fall mounting base plate assembly 311 to ensure that the docking plate 309 passes through the movable limiting plug 312 and the two are tightly fitted, so as to complete the height positioning and stable reinforcement of the anti-fall mounting base plate assembly 311. On both sides of the limiting guide plate 313 fixedly connected to the bottom surface of the anti-fall mounting base plate assembly 311.

[0040] Through the guide opening 314 on the side surface of the limiting guide plate 313, the limiting plug plate 315 is inserted into the limiting guide plate 313. The insertion depth of the limiting plug plate 315 is adjusted according to the width of the elevator landing door to expand the lateral coverage of the limiting guide plate 313 and reinforce its structure. The second telescopic rod 316 fixedly connected to one side of the limiting guide plate 313 is activated, causing the second telescopic rod 316 to extend towards the gap of the elevator landing door, driving the reinforcing plate 317 connected to one side of the second telescopic rod 316 to move synchronously until the anti-falling door elevator protection plate 318 fixedly connected to one side of the reinforcing plate 317 completely covers the gap of the elevator landing door. Since the reinforcing plate 317 is symmetrical about the vertical centerline of the anti-falling door elevator protection plate 318, the reinforcement plate 317 is used as the reference. The device is symmetrically configured to ensure that the reinforcing plates 317 on both sides and the second telescopic rod 316 are adjusted synchronously to keep the anti-falling elevator door guard plate 318 horizontal and evenly stressed. This completes the assembly of the entire device and activates its protective function. During operation, the anti-falling elevator door guard plate 318 continuously blocks debris from falling, while the first telescopic rod 310 and the second telescopic rod 316 maintain the stability of the protective structure. If maintenance is required, the above steps can be reversed. The limiting plug plate 315 can be removed through the guide opening 314, the first telescopic rod 310 and the second telescopic rod 316 can be retracted, and the docking collar 308 and the snap-fit ​​shaft 303 can be disassembled to complete the component inspection or replacement. After inspection, the device can be reassembled according to the above procedure to restore its protective function.
