[0025] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0026] See Figures 1 to 7 As shown, this utility model embodiment provides a top plate structure for a heavy-duty, ultra-wide elevator, including a top plate connector 3, a splicing connector 4, and at least two top plate assemblies 1.

[0027] The top plate structure of this utility model adopts a left-right splicing method to ensure uniform distribution of the load and reduce the production cost of the top plate.

[0028] Specifically, the top plate assembly 1 includes at least two top plate units 2, and a plurality of top plate units 2 are arranged and connected along their width direction to form the top plate assembly 1. The plurality of top plate units 2 are connected by the top plate connector 3. The top plate connector 3 includes a first support wall 31, one side of the first support wall 31 is bent away from the top plate unit 2 to form a second support wall 32, and the first support wall 31 is connected to the plurality of top plate units 2 by a first fastener 33.

[0029] Multiple top plate components 1 are arranged and spliced ​​along their length, and two adjacent top plate components 1 are connected by the splicing connector 4.

[0030] The top plate structure of this utility model includes a top plate connector 3, a splicing connector 4, and at least two top plate assemblies 1. Each top plate assembly 1 includes at least two individual top plate units 2. Multiple top plate units 2 are arranged and connected along their width to form the top plate assembly 1. Multiple top plate assemblies 1 are also arranged and spliced ​​along their length. Two adjacent top plate assemblies 1 are connected by the splicing connector 4. Firstly, standardized top plate units 2 are used for splicing, eliminating limitations on the maximum machined length. Secondly, the modular structure facilitates transportation and on-site assembly, requiring only the top plate connector 3 and the splicing connector 4 for assembly. Finally, the top plate connector 3 includes a first support wall 31. One side of the first support wall 31 is bent away from the top plate unit 2 to form a second support wall 32. The first support wall 31 is connected to multiple top plate units 2 by a first fastener 33, ensuring uniform distribution of dynamic load on the top plate and avoiding localized stress concentration problems that may exist in traditional arrangement methods.

[0031] It should be noted that the above-mentioned top plate connector 3 can be made of reinforcing angle steel. In specific implementation, an angled pressure plate can be used to press down the bent edge of each top plate unit 2, and then the bolts can be tightened to fix it to the reinforcing angle steel.

[0032] In some embodiments, the first support wall 31 is arranged parallel to the width direction of the top plate assembly 1. The first support wall 31 is provided with a plurality of first fastening holes 34. The positions of the first fastening holes 34 correspond one-to-one with the positions of the top plate unit 2. The first fasteners 34 pass through the top plate unit 2 and the first support wall 31 in sequence, and fix the top plate unit 2 and the first support wall 31 in a fixed connection.

[0033] The first support wall 31 is positioned parallel to the width direction of the top plate assembly 1, and together with the equidistant distribution of multiple first fastening holes 34, forms a grid-like stress structure. Each fastening point transmits the local load of the top plate unit laterally to the adjacent top plate unit 2 through the first support wall 31, avoiding stress concentration and achieving a load-sharing effect.

[0034] The length of the top plate assembly 1 is L, and its width is W, where L:W = 1:(2-5). It should be noted that the length-to-width ratio of the top plate assembly 1 creates a continuous beam effect in the length direction. Through the longitudinal connection of the first support wall 31, the weight load distribution capacity of the elevator car top plate is significantly improved when maintenance personnel stand on the elevator car top plate for maintenance.

[0035] In some embodiments, the splicing connector 4 includes a light-shielding plate 41 and two mutually symmetrical decorative plates 42;

[0036] Two mutually symmetrical decorative panels 42 are disposed between two top plate assemblies 1. Each decorative panel 42 has a plurality of second fastening holes 44 arranged in a straight line. The second fasteners 44 pass through the top plate assembly 1 and the second fastening holes 43 in sequence to fasten the decorative panels 42 and the top plate assembly 1. The light-shielding plate 41 is disposed at the bottom of the two decorative panels 42 to cover the gap at the bottom of the two decorative panels 42.

[0037] First, the decorative panel 42 is bolted to the two side top panel assemblies 1 via linearly arranged second fastening holes 43, forming a continuous constraint band. This design binds adjacent top panel assemblies 1 together at the joint, significantly improving the interface's shear resistance and preventing misalignment and deformation of the joint due to dynamic loads. Second, the dense arrangement of multiple second fasteners 44 allows concentrated loads in the joint area, such as those borne by maintenance personnel, to be diffused through the decorative panel to the individual top panels on both sides, avoiding localized stress concentration that could lead to top panel deformation.

[0038] Preferably, the decorative panel 42 includes a first connecting plate 45, the two sides of the first connecting plate 45 are bent toward the top plate unit 2 to form a second connecting plate 46, and the second connecting plate 46 is parallel to the top plate unit 2.

[0039] In some embodiments, the top plate assembly 1 is provided with a reinforcing channel steel 5 on the bottom side near another adjacent top plate assembly 1.

[0040] Preferably, the top plate unit 2 is composed of a decorative panel layer 21, a silane adhesive layer 22, a fixing layer 23, and functional layers of various components from bottom to top, and the functional layers of various components 24 include a crossflow fan, a lighting component, and a door machine mounting groove.

[0041] Specifically, the lighting assembly 24 includes a light-transmitting plate 26, a downlight 27, and a lampshade 28.

[0042] Accordingly, this utility model embodiment also provides a high-load, ultra-wide elevator, including the aforementioned top plate structure.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
