Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and more specifically, to a safety guardrail suitable for the entrance and exit platforms of escalators. Background Technology

[0002] Escalators are fixed, electrically driven devices that rely on their circulating steps to transport passengers upwards or downwards. At their entrances and exits, there are specially reserved mounting slots where key components for the escalator's operation are installed, such as the motor and speed reducer that power the steps, components ensuring smooth step rotation, and electrical control elements that manage the entire system. The mounting slots are then covered with metal plates for insulation and protection.

[0003] When escalators connect floors, guardrails must be installed on both sides of the entrance and exit to prevent users from accidentally falling from the side. Currently, since metal plates are installed at the entrances and exits, the common method for installing guardrails is to install them on top of the metal plates, using connectors to penetrate the metal plates and connect them to the steel beam structure in the mounting groove below. However, this installation method has many problems in practice. During installation, the connectors must penetrate the metal plate, which is very difficult, requiring precise drilling and careful alignment. This is time-consuming and labor-intensive, and even slight errors can easily lead to installation deviations, affecting subsequent use. Moreover, during escalator maintenance and repair, the guardrails greatly hinder the work, making it difficult for maintenance personnel to easily access the parts that need repair. If the guardrails themselves need replacement or maintenance, the metal plates must be disassembled and reassembled, making the entire process cumbersome and inconvenient, increasing maintenance costs and time.

[0023] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0024] Please refer to Figures 1-4 This application provides a safety guardrail suitable for escalator entrance and exit platforms, comprising: a guardrail body; a connecting bracket 5, including a connecting plate 501 and a guide member 502, wherein the connecting plate 501 is disposed at the bottom of the guardrail body, the guide member 502 is inclinedly disposed at the bottom of the connecting plate 501, and the end of the guide member 502 away from the connecting plate 501 extends to the outside of the side of the connecting plate 501; an embedded plate 6 for pre-embedding in the outer wall of the escalator entrance and exit platform, which is detachably engaged with the end of the guide member 502 away from the connecting plate 501; wherein, when the embedded plate 6 and the guide member 502 are connected, the connecting plate 501 and the embedded plate 6 form an angled space; and an angled connector 7 disposed in the angled space for connecting the connecting plate 501 and the embedded plate 6, and both the connecting plate 501 and the embedded plate 6 are detachably engaged with the angled connector 7.

[0025] The safety guardrail involved in this application has a convenient and effective installation process in practical application. First, the installation position of the guardrail must be accurately determined, and the embedded plate 6 is pre-embedded into the outer wall of the escalator entrance / exit platform, which is the outer wall of the floor slab. Next, using angle connectors 7, the embedded plate 6 is securely connected to the connecting bracket 5. Based on this, the safety guardrail is installed on the upper side of the connecting plate 501 of the connecting bracket 5. This design cleverly creates an installation point on the outer wall of the floor slab for the guardrail installation. Compared to traditional installation methods, its advantages are obvious. On the one hand, it completely avoids the tedious and error-prone operation of drilling holes in the metal plate, reducing installation difficulty and the risk of error; on the other hand, since the guardrail is not installed on top of the metal plate, subsequent maintenance and repair work on the escalator will not be obstructed by the guardrail. Furthermore, when the guardrail itself needs repair or replacement, it can be carried out smoothly without interference from external factors, effectively improving overall practicality.

[0026] In a preferred embodiment, the guardrail includes two parallel and spaced-apart railing posts 1, a transparent glass plate 2 is provided between the two railing posts 1, and a handrail 3 is connected to the upper side of the two railing posts 1.

[0027] Each of the above-mentioned railing posts 1 is provided with the above-mentioned connecting bracket 5, the above-mentioned embedded plate 6 and the above-mentioned angle connector 7 on its bottom side.

[0028] In the above embodiment, two parallel and spaced railing posts 1 are combined with transparent glass panels 2 and handrails 3, which are structurally stable and provide comprehensive protection. They can effectively prevent users from falling from the side without affecting their view. The handrails 3 can also provide passengers with additional gripping support points, enhancing the safety of use.

[0029] In a preferred embodiment, the top of the railing post 1 is provided with an inclined mounting member 4, and the inclined direction of the mounting member 4 is the same as the inclined direction of the guide member 502. The handrail 3 is provided at the end of the mounting member 4 away from the railing post 1.

[0030] In the above embodiment, the handrail 3 is inclined towards the inside of the transparent glass panel 2 to facilitate gripping. Mounting members 4 are provided at the top of both railing posts 1 to improve the stability of the handle 3.

[0031] In a preferred embodiment, any of the above-mentioned railing posts 1 and their connected connecting plates 501 and angle connectors 7 are detachably connected by bolts.

[0032] The aforementioned angle connector 7 and the aforementioned embedded plate 6 are detachably connected by another set of bolts.

[0033] In the above embodiments, any railing post 1 and its connected connecting plate 501 and angle connector 7 are detachably connected by bolt groups. During installation, this facilitates precise alignment and rapid assembly of each component, effectively improving installation efficiency and reducing installation difficulty.

[0034] In a preferred embodiment, there are two guide members 502, which are respectively disposed at both ends of the connecting plate 501.

[0035] In the above embodiment, two guide members 502 are distributed at both ends of the connecting plate 501, which can guide the installation of the guardrail more accurately and stably, so that the guardrail can be precisely matched with the surrounding structure during the assembly process, ensuring the accuracy of the overall installation, reducing installation errors, and effectively improving installation efficiency.

[0036] As a preferred embodiment, the structure formed by the connecting plate 501 and the two guide members 502 is an integrally formed structure.

[0037] In the above embodiments, the integral molding structure has strong integrity and is less prone to guide failure or structural damage caused by loosening or breakage at the connection, thereby enhancing the guardrail's ability to resist external impacts and extending its service life.

[0038] As a preferred implementation method, the aforementioned embedded plate 6 is made of galvanized steel plate.

[0039] In the above embodiments, the galvanized steel sheet possesses excellent corrosion resistance. In relatively humid environments such as escalator entrances and exits, with frequent personnel traffic and potential exposure to various moisture and chemicals, it effectively resists rust, maintains structural strength over a long period, ensures a stable connection between the embedded plate 6 and the connectors, and extends its service life. Secondly, the presence of the galvanized layer increases the surface hardness of the steel sheet, making it more wear-resistant and reducing surface damage caused by friction and collisions during daily use, further ensuring the integrity of the embedded plate 6.

[0040] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The terms "upper," "lower," "left," "right," "inner," "outer," and "side," etc., are merely for reference to the direction in the accompanying drawings or the usual placement of the product during use. They are only for clearly describing this application and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limitations on this application.
