Description

Technical Field

[0001] The utility model relates to an elevator car roof, in particular to a riveted car roof structure. Background Art

[0002] To enhance its structural strength and deformation resistance, elevator car roofs are designed with multiple reinforcing ribs installed on the roof panel. These ribs are crisscrossed and interconnected, providing overall reinforcement for the roof panel. To achieve this connection between the ribs and between the ribs and the roof panel, manufacturers must weld the ribs together. However, as manufacturers increase their demands for ease of assembly and environmental friendliness, the traditional assembly method of directly welding individual parts into shape no longer meets their production needs. Therefore, a new elevator car roof structure is needed that reduces the amount of welding required by operators during assembly. Utility Model Content

[0003] The purpose of the utility model is to provide a press-riveted car roof structure, which can reduce the welding operations during the assembly process of the elevator car roof.

[0004] The technical solution of the utility model is as follows: a riveted car roof structure, including a car roof plate, a mounting opening being provided in the middle of the car roof plate, a first reinforcing rib being provided at the bottom of the car roof plate, located on the outside of both ends of the mounting opening, a plurality of second reinforcing ribs being arranged side by side between the first reinforcing ribs on both sides, both ends of the first reinforcing rib and the second reinforcing rib extending to the car roof plate outside the mounting opening and fixedly connected to the car roof plate, a third reinforcing rib being connected between the first reinforcing rib and the second reinforcing rib, and between adjacent second reinforcing ribs, the tops of the second and third reinforcing ribs being connected with a cover plate located in the mounting opening, and the cover plate being riveted to the second and third reinforcing ribs, respectively.

[0005] In the aforementioned riveted car roof structure, there are multiple cover plates, and each cover plate is connected to the second reinforcing rib and multiple third reinforcing ribs at the same time.

The upper end of the front mounting plate extends to the top of the car roof panel through a bent portion and is bolted to the car roof panel. The bent portion is located at the interval between the first mounting strips on both sides.

[0008] In the aforementioned riveted car roof structure, multiple L-shaped limit plates are detachably connected around the bottom of the car roof panel. The multiple limit plates are enclosed together to form an annular limit frame, and the side walls of the limit frame are in contact with the first and second reinforcement ribs.

[0009] Compared with the prior art, the present invention has the following features:

[0010] (1) The present invention defines the structure of the first and second reinforcing ribs so that the first and second reinforcing ribs can be fixedly connected to the car roof plate and provide support for the third reinforcing rib and the cover plate. On this basis, by defining the coordination between the third reinforcing rib and the cover plate, the cover plate can limit the third reinforcing rib after riveting, so that the third reinforcing rib and the second reinforcing rib maintain a fixed position after being spliced together, and then the third reinforcing rib is used to reinforce the first and second reinforcing ribs, thereby improving the overall structural strength and stability of the car roof.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0018] Example. The riveted car roof structure is composed of Figure 1As shown, it includes a car top plate 1, a mounting opening 2 is provided in the middle of the car top plate 1, and a first reinforcing rib 3 is provided at the bottom of the car top plate 1, which is located on the outside of both ends of the mounting opening 2. The edge of the first reinforcing rib 3 is flush with the mounting opening 2, and a number of second reinforcing ribs 4 are arranged side by side between the first reinforcing ribs 3 on both sides. Both ends of the first reinforcing rib 3 and the second reinforcing rib 4 extend to the car top plate 1 outside the mounting opening 2 and are fixedly connected to the car top plate 1, and third reinforcing ribs 5 are connected between the first reinforcing rib 3 and the second reinforcing rib 4, as well as between adjacent second reinforcing ribs 4. The third reinforcing rib 5 and the first reinforcing rib 3 and the second reinforcing rib 4 are arranged perpendicular to each other, and the tops of the second reinforcing ribs 4 and the third reinforcing ribs 5 are connected to a cover plate 6 located in the mounting opening 2, and the edges of the cover plate 6 are in contact with the side walls of the mounting opening 2, and the cover plate 6 is riveted to the second reinforcing rib 4 and the third reinforcing rib 5 respectively.

[0019] There are multiple cover plates 6, each of which is connected to the second reinforcing rib 4 and multiple third reinforcing ribs 5 at the same time. Operation ports for wiring or installation and maintenance can be set on the cover plates 6 as needed, and the outside of some operation ports is detachably connected to an operation panel.

[0020] The top of the car top plate 1 is respectively provided with a first mounting strip 7 located on the left and right sides of the mounting opening 2 and a second mounting strip 8 located at one end of the mounting opening 2. The side walls of the mounting strip are flush with the edges of the mounting opening 2. The middle part of the first mounting strip 7 is connected to the car top plate 1 and the first reinforcing rib 3 by bolts, and the two ends of the first mounting strip 7 are connected to the car top plate 1 and the second reinforcing rib 4 by bolts. The second mounting strip 8, the car top plate 1 and the second reinforcing rib 4 are connected to each other by bolts.

[0021] The car roof panel 1 can be formed by welding a plurality of sub-panels together after being assembled, or can be formed by connecting and fixing a plurality of sub-panels together through the cooperation of the first reinforcing ribs 3 and the second reinforcing ribs 4 after being assembled.

[0022] The car top panel 1 is provided with a front mounting plate 9 at one end away from the second mounting strip 8.
