Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and more specifically, to a compact elevator landing door device. Background Technology

[0002] With the rapid development of society, elevators have become an indispensable part of daily travel for the public, and people's requirements for elevator quality are constantly increasing. The landing door system is a core component that serves as the first line of defense for people entering the elevator.

[0003] The elevator market has matured, with numerous brands and fierce competition. In the current economic environment, cost reduction and efficiency improvement have become crucial for companies to enhance their competitiveness. Currently, in elevator landing door systems, such as... Figure 3 As shown, the limiting structure located below the guide rail adopts a "limiting wheel + stop" form. This structure requires a set of limiting wheel assemblies to be installed on both the left and right sides of each door panel, resulting in a large number of parts and higher costs. After long-term operation, the limiting wheels are prone to wear and noise, affecting user experience and product quality. Secondly, the material usage of the landing door base plate itself is relatively high, further increasing manufacturing costs and resulting in a high overall cost of current elevator landing door devices.

[0004] Elevator landing door devices are a critical component used in large quantities and are a key area for optimization and upgrading. Therefore, there is an urgent need to develop a low-cost, quiet, and impact-resistant compact elevator landing door device to save costs and enhance the overall structural strength and stability.

The bottom of the base plate is flat and vertically installed against the inner wall of the top of the elevator landing door. The cross-section of the bottom edge of the base plate extending away from the wall forms a semi-Ω shape, and a guide rail is provided on the upwardly protruding part of the Ω shape; a door hanger assembly, including a sliding part and a door hanger part, with rollers provided on the sliding part. The rollers are in contact with the guide rail so that the door hanger assembly can move horizontally along the guide rail; and a guide shoe assembly, which is connected to the door hanger assembly. The guide shoe assembly is fixedly connected to the bottom plate and is set parallel to the bottom plate. The guide shoe assembly includes a hook-shaped guide shoe plate with an upwardly curved cross section. The rope wheel assembly includes a rope wheel and a linkage rope. There are two rope wheels. The rope wheels are installed at the bottom position of the bottom plate near the bottom plate and at both ends near the two ends of the bottom plate in the direction of extension. The linkage rope is wound around the rope wheel and passes through it, and can pull the door hanging plate assembly to move horizontally along the guide rail. The bottom plate extends to the hook-shaped inner side of the guide shoe plate at the Ω-shaped end of the guide rail, and cooperates with the guide shoe plate to limit the door hanging plate assembly and prevent the door hanging plate assembly from falling upward.

[0007] According to an embodiment of the present invention, the guide shoe assembly may further include: a guide shoe, which is U-shaped and disposed within the hook shape of the guide shoe plate, for separating the guide shoe plate and the bottom plate to buffer vibration impact.

[0008] Furthermore, the guide shoe is detachably installed inside the hook shape of the guide shoe plate, making it easy to replace after wear.

[0009] According to an embodiment of this utility model, the guide shoe can be made of non-metallic wear-resistant material, and the guide shoe plate can be made of metallic material.

[0010] According to an embodiment of the present invention, the door hanging part may have a hanging plate, and the hanging plate is provided with an anti-detachment hook. The anti-detachment hook is vertically arranged on the left and right sides of the hanging plate, protruding downwards and extending to the inner side of the Ω-shaped recess at the bottom edge of the base plate, so as to prevent the door hanging plate assembly from falling off or detaching from the guide rail.

[0011] According to an embodiment of this utility model, there may be two door hanging components, which can be opened or closed relative to each other after being pulled and linked by the rope wheel assembly.

[0012] According to an embodiment of the present invention, the two door hanging panel assemblies can be a left door hanging panel assembly and a right door hanging panel assembly, the door hanging part of the left door hanging panel assembly includes a left layer door hanging panel, and the door hanging part of the right door hanging panel assembly includes a right layer door hanging panel. The left layer door hanging panel and the right layer door hanging panel can be opened and closed relative to each other.

[0013] According to an embodiment of the present invention, the compact elevator landing door device may further include: a door lock assembly, which includes a lock hook and a landing door lock, respectively fixed to the left and right landing door hanging plates to achieve the function of locking the landing door to prevent the landing door from opening.

[0014] According to an embodiment of the present invention, the door lock assembly may further include: a contact switch and a contact switch bracket, wherein the contact switch bracket is connected to a connection point provided on the top of the base plate to further reinforce the strength of the base plate and enhance the strength and stability of the overall structure.

[0015] According to an embodiment of the present invention, the compact elevator landing door device may further include: a counterweight assembly for realizing the forced door closing function, the counterweight assembly being connected to the door hanger via a counterweight pulley.

[0016] Compared with the prior art, the technical solution provided by the embodiments of this utility model can achieve at least the following beneficial effects:

[0017] The compact elevator landing door device of this utility model adopts a single guide shoe, which replaces the existing landing door device with two sets of "limiting wheels + blocks" below the guide rail. The technical solution of this utility model is simple to manufacture, easy to install, uses fewer parts, and has a lower cost.

[0018] The landing door device of this utility model adopts a guide shoe design, which has the advantages of being simple to manufacture, easy to install, requiring fewer units, and having lower costs. Secondly, the reduced height of the base plate saves material costs, resulting in a more compact overall structure and better impact resistance. The addition of a connection point between the contact switch bracket and the top of the base plate further strengthens the base plate, enhancing the overall structural strength and stability.

[0019] According to the compact elevator landing door device of this utility model, the limiting wheel device is eliminated, and more space can be freed up below the hanging plate for arranging the counterweight assembly. After the counterweight assembly, which originally needed to be arranged above the hanging plate, is moved to below the hanging plate, the height of the base plate is also reduced, making the overall structure more compact and the impact resistance better. At the same time, the base plate, which uses the most material, saves materials and reduces costs due to the reduction in height.

[0020] According to the compact elevator landing door device of this utility model, the height of the base plate is reduced, the structure is more compact, and the contact switch bracket is not only fixed on the guide rail, but also has an additional connection point between the contact switch bracket and the top of the base plate, which further strengthens the base plate and enhances the strength and stability of the overall structure.
