Description

Technical Field

[0001] This utility model belongs to the field of elevator landing door technology, and specifically relates to an elevator landing door and an anti-detachment structure. Background Technology

[0002] The existing elevator landing door guide rails lack a cleaning mechanism, leading to the accumulation of dust and debris over time. This increases the running resistance of the guide rails and may cause derailment. Furthermore, the lack of a reliable limiting structure between the guide rollers and the guide rails means that if the landing door panel is impacted, the guide rollers and guide rollers can easily detach from the guide rails, affecting the normal operation of the elevator. These defects mainly stem from the fact that traditional guide rail designs only consider mechanical guiding functions and have not optimized dustproof and anti-detachment structures. This results in changes in the friction coefficient after dust accumulation, causing the guide rollers to deviate from their running trajectory. Additionally, excessive gaps or insufficient limiting between the guide rollers and the guide rails fail to effectively constrain the lateral displacement of the landing door panel, making it prone to mechanical detachment upon impact.

[0003] Conventional solutions include regular manual cleaning of the guide rails, adding dust covers, or adjusting the gap between the guide rollers. However, manual cleaning is inefficient and difficult, dust covers may affect heat dissipation from the guide rails and increase maintenance complexity, and adjusting the gap between the guide rollers only alleviates some displacement issues and cannot fundamentally solve the risk of disengagement caused by impact. Furthermore, some improvement solutions attempt to reinforce the roller brackets or use elastic limiting components, but increased structural complexity may increase manufacturing costs, and elastic components are prone to aging and failure, resulting in insufficient long-term reliability. Therefore, we aim to design an elevator landing door with a novel structure to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an elevator landing door and an anti-detachment structure to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: an elevator landing door and anti-detachment structure, comprising: a landing door assembly, the upper end of which is movably connected to a guide rail assembly, the landing door assembly including a landing door body and a first hanging plate and a second hanging plate for suspending and installing the landing door body, the upper ends of the two landing door bodies being fixedly connected to the lower ends of the first hanging plate and the second hanging plate, respectively.

[0006] A cleaning component for cleaning the guide rail assembly is rotatably installed on the upper left and upper right sides of each of the first and second mounting plates. A guide wheel for guiding and limiting is rotatably installed on the lower left and lower right sides of each of the first and second mounting plates.

[0007] In a preferred embodiment, the cleaning component includes a gear ring for transmitting power. The gear ring is located on the side of the roller near the first and second hanging plates, and the diameter of the gear ring is larger than the diameter of the roller. The cleaning component rotates under the drive of the movement of the hanging wheel to clean the first and second guide rails, preventing debris from covering the upper side of the first and second guide rails and causing interference to the running of the hanging wheel, which could lead to the risk of it dislodging.

[0008] In a preferred embodiment, the roller is rotatably mounted on the side of the mounting plate 1 and the mounting plate 2 where the roller is mounted, and the outer wall of the roller is provided with a ring of bristles.

[0009] In a preferred embodiment, the landing door assembly further includes a hanging wheel. A hanging wheel for supporting the landing door body is rotatably installed on the upper left and upper right sides of the first and second hanging plates, respectively. A gear ring two is provided on one edge of the hanging wheel near the first and second hanging plates. The outer wall of the gear ring two is provided with a ring of teeth distributed in a circular structure. The gear ring two is connected to the gear ring one through the meshing of its teeth to form a power transmission.

[0010] In a preferred embodiment, the guide rail assembly includes a guide rail one and a guide rail two. The guide rail two is installed on the left front side of the guide rail one. The outer wall of the pulley is radially recessed inward to form an annular groove with an inwardly concave arc-shaped cross-section. The multiple pulleys are respectively connected to the guide rail one and the guide rail two through the annular groove.

[0011] In a preferred embodiment, the bristles located on the lower side of the roller rotate and abut against the upper side of guide rail one and guide rail two, and the width of the bristles is greater than the width of guide rail one and guide rail two.

[0012] In a preferred embodiment, the lower ends of both guide rail one and guide rail two are recessed upward to form a sliding groove. The lower sides of guide rail one and guide rail two are tactilely connected to two guide wheels. Limiting rings are provided on the guide wheels. The added limiting rings, together with the sliding grooves on the lower sides of guide rail one and guide rail two, can guide the operation of the entire landing door and provide a limiting effect on the lower side of the hanging plate, effectively preventing the hanging plate and the landing door body from detaching during long-term operation or impact.

[0013] In a preferred embodiment, the stop wheel includes a wheel body and a limiting ring. The side of the wheel body closest to the first and second hanging plates is rotatably connected to the first and second hanging plates. A limiting ring is provided in the middle of the outer wall of the wheel body. The diameter of the limiting ring is larger than the diameter of the wheel body. The width of the limiting ring is the same as the width of the slide groove, and the limiting ring is rotatably connected to the slide groove. The wheel body is rotatably connected to the lower side of the first and second guide rails.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by adding cleaning components to the first and second hanging plates, the rotating bristles will clean the debris on the first and second guide rails. Regardless of whether the first and second hanging plates move to the left or to the right, the cleaning components on both sides will clean the guide rails on the first and second guide rails on which the hanging wheel travels, effectively reducing the risk of debris covering the upper side of the first and second guide rails, which may cause interference and separation during the operation of the hanging wheel.

[0015] By setting up stop rollers and setting limit rings on the stop rollers, the added limit rings, together with the sliding grooves on the lower side of guide rail one and guide rail two, can guide the entire operation of the landing door and provide a limiting effect on the lower side of the hanging plate, effectively preventing the hanging plate and the landing door body from detaching during long-term operation or impact.

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.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: an elevator landing door and an anti-detachment structure, including: a landing door assembly 100, the upper end of the landing door assembly 100 being movably connected to a guide rail assembly 200, the landing door assembly 100 including a landing door body 110 and a first hanging plate 120 and a second hanging plate 130 for suspending and installing the landing door body 110, the upper ends of the two landing door bodies 110 being fixedly connected to the lower ends of the first hanging plate 120 and the second hanging plate 130 respectively;

[0025] A cleaning component 140 for cleaning the guide rail assembly 200 is rotatably installed on the upper left and upper right sides of the first mounting plate 120 and the second mounting plate 130, respectively. A guide wheel 160 for guiding and limiting is rotatably installed on the lower left and lower right sides of the first mounting plate 120 and the second mounting plate 130, respectively.

[0026] Please see Figures 1 to 4 The cleaning component 140 includes a gear ring 141 for transmitting power. The gear ring 141 is located on the side of the roller 143 near the first hanging plate 120 and the second hanging plate 130, and the diameter of the gear ring 141 is larger than the diameter of the roller 143. The cleaning component 140 is designed to rotate under the motion drive of the roller 150 to clean the first guide rail 210 and the second guide rail 220, so as to prevent debris from covering the upper side of the first guide rail 210 and the second guide rail 220, which would cause the roller 150 to be disturbed during operation and risk of disengagement.

[0027] The roller 143 is rotatably mounted on the side of the mounting plate 120 and the mounting plate 2130 where the roller 150 is mounted. A ring of bristles 142 is provided on the outer wall of the roller 143.

[0028] The landing door assembly 100 also includes a hanging wheel 150. A hanging wheel 150 for supporting the landing door body 110 is rotatably installed on the upper left and upper right sides of the first hanging plate 120 and the second hanging plate 130, respectively. A gear ring 2 is provided on the edge of the hanging wheel 150 near the first hanging plate 120 and the second hanging plate 130. A ring of teeth with a circular structure is provided on the outer wall of the gear ring 2. The gear ring 2 is connected to the gear ring 1 through the meshing of its teeth to form a power transmission.

[0029] The guide rail assembly 200 includes a first guide rail 210 and a second guide rail 220. The second guide rail 220 is installed on the left front side of the first guide rail 210. The outer wall of the pulley 150 is radially recessed to form an annular groove with an inwardly concave arc-shaped cross section. Multiple pulleys 150 are respectively connected to the first guide rail 210 and the second guide rail 220 through the annular groove.

[0030] The bristles 142 located on the lower side of the roller 143 rotate and abut against the upper side of the guide rail 1 210 and the guide rail 2 220, and the width of the bristles 142 is greater than the width of the guide rail 1 210 and the guide rail 2 220.

[0031] As the first embodiment of this utility model, by adding a cleaning component 140 to the first hanging plate 120 and the second hanging plate 130, in actual use, when the first hanging plate 120 and the second hanging plate 130 are running, the hanging wheel 150 on them rolls with the first guide rail 210 and the second guide rail 220. At this time, the hanging wheel 150 is in a rotating state. Since the outer wall of the gear ring 2 is provided with a ring of teeth distributed in a circular structure, the gear ring 2 is connected to the gear ring 1 through the meshing of its teeth to form a power transmission. In addition, the outer wall of the roller 143 is provided with a ring of bristles 142. When the hanging wheel 150 rotates, it will drive the gear ring 141 to rotate, thereby driving the roller 143 located on the outer wall of the roller 143 to rotate. The brush bristles 142 rotate, and because the brush bristles 142 on the lower side of the roller 143 rotate and abut against the upper side of the guide rail 1 210 and the guide rail 2 220, the width of the brush bristles 142 is greater than the width of the guide rail 1 210 and the guide rail 2 220. The rotating brush bristles 142 will clean the debris on the guide rail 1 210 and the guide rail 2 220. Regardless of whether the hanging plate 1 120 and the hanging plate 2 130 move to the left or to the right, the cleaning parts 140 on both sides will clean the guide rail 1 210 and the guide rail 2 220 on which the roller 150 travels. This effectively reduces the risk of debris covering the upper side of the guide rail 1 210 and the guide rail 2 220, which could interfere with the operation of the roller 150 and cause it to fall off.

[0032] Please see Figures 2 to 4 The lower ends of guide rail 1 210 and guide rail 2 220 are both recessed upward to form a groove 221. The lower sides of guide rail 1 210 and guide rail 2 220 are both rolledly connected to two stop wheels 160. A limit ring 161 is set on the stop wheel 160. The added limit ring 161, together with the groove 221 on the lower side of guide rail 1 210 and guide rail 2 220, can guide the operation of the entire landing door and provide a limiting effect on the lower side of the hanging plate, effectively preventing the hanging plate and the landing door body 110 from detaching during long-term operation or impact.

[0033] The stop wheel 160 includes a wheel body 162 and a limiting ring 161. The side of the wheel body 162 closest to the first hanging plate 120 and the second hanging plate 130 is rotatably connected to the first hanging plate 120 and the second hanging plate 130. The limiting ring 161 is provided in the middle of the outer wall of the wheel body 162. The diameter of the limiting ring 161 is larger than the diameter of the wheel body 162. The width of the limiting ring 161 is the same as the width of the slide groove 221, and the limiting ring 161 is tumbledly connected to the slide groove 221. The wheel body 162 is tumbledly connected to the lower side of the first guide rail 210 and the second guide rail 220.

[0034] As a second embodiment of this utility model, based on the first embodiment described above, by setting a stop wheel 160 and setting a limiting ring 161 on the stop wheel 160, since the lower sides of the guide rail 1 210 and the guide rail 220 are both rolledly connected to the two stop wheels 160, and the width of the limiting ring 161 is the same as the width of the slide groove 221, the limiting ring 161 is rolledly connected to the slide groove 221, and the wheel body 162 is rolledly connected to the lower side of the guide rail 1 210 and the guide rail 220, the added limiting ring 161, together with the slide groove 221 on the lower side of the guide rail 1 210 and the guide rail 220, can guide the entire operation of the landing door and provide a limiting effect on the lower side of the hanging plate, effectively preventing the hanging plate and the landing door body 110 from detaching during long-term operation or impact.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
