Abstract
Description
Technical Field
[0001] The utility model relates to an elevator car roof, belonging to the technical field of elevators. Background Art
[0002] An elevator is a permanent transport device that serves specific floors within a building, with its car running on at least two rigid tracks perpendicular to the horizontal plane or inclined at an angle of less than 15° to the vertical. Modern elevators primarily consist of a traction system (winch), guide rails, counterweight, safety devices (such as speed limiters, safety clamps, and buffers), a signal control system, a car, and landing doors. These components are installed in the building's hoistway and machine room, respectively. A wire rope friction drive is typically used. The wire rope passes over a traction sheave, with each end connected to the car and counterweight. An electric motor drives the traction sheave to raise and lower the car.
[0003] Generally speaking, the car roof layout structure of traditional elevators is composed of one or more car roof panels. The car roof panels are made of bent plates with reinforcing ribs welded in the middle to ensure overall strength, which makes the overall car roof structure heavier and increases the load on the traction system.

[0025] Please refer to Figures 1 to 2 An elevator car roof is arranged on the top of a car 10. The elevator car roof includes a car roof frame structure 20 and a car roof main body 30, which are used to block and support the top of the car 10.
[0026] The car top frame structure 20 is mounted on the inner wall of the top of the car 10. A support plane 21 is formed within the car top frame structure 20, extending toward the axis of the car 10. In this embodiment, the car top frame structure 20 is a quadrilateral support frame formed by four angle steel support bars. The ends of the four angle steel support bars are welded and fixed in sequence, and the support plane 21 is formed within the car top frame structure 20. Of course, in other embodiments, the car top frame structure 20 can also be formed by another number of L-shaped support bars, such as three or five, and the number can be set as needed and is not specifically limited here.
[0027] Please refer to Figure 3In another embodiment, the car roof frame structure 20 is arranged on the upper surface of the top of the car 10, and the projection of the supporting plane 21 in the vertical direction falls on the upper surface of the car wall of the car 10, which is convenient for the installation and fixation of the car roof frame structure 20. When the car roof main body 30 is arranged in the car roof frame structure 20, the edge of the car roof main body 30 is overlapped on the top of the car 10 through the car roof frame structure 20, which is beneficial to improve the supporting strength of the car roof.
[0028] Please refer to Figures 1 to 2 The car top main body 30 is installed within the car top frame structure 20, with its bottom edge abutting the support plane 21 to seal the top of the car 10. The shape of the car top main body 30 matches the shape of the support plane 21 within the car top frame structure 20. The car top main body 30 is placed on the car top frame structure 20 and overlaps the support plane 21 to achieve a seal on the top of the car 10. The car top main body 30 is made of a non-combustible, non-toxic, high-strength material that meets the stress requirements of the car top, such as glass fiber reinforced plastic. Its density is lower than that of metal, which can effectively reduce the weight of the car top, facilitate the lightweight design of the car 10, and reduce the energy consumption of the elevator.
[0029] In one embodiment, the car top main body 30 is a rectangular plate. The car top frame structure 20 is also a square frame. When the car top main body 30 is arranged within the car top frame structure 20, the upper surfaces of the two are flush with each other and are also flush with the upper surface of the car 10. This forms a flat top that facilitates the arrangement and installation of other equipment or accessories on the car top, making more efficient use of the space on the top of the entire car 10. At the same time, the entire car top surface can be made highly flat, making it easier for car top operators to work.
[0030] In one embodiment, a plurality of through holes 31 are formed in the rectangular plate at intervals along its length or width. While meeting strength requirements, the rectangular plate is configured to have a plurality of hollow through holes 31 formed therein, which can effectively reduce the overall weight of the car 10. The through holes 31 can be rectangular or circular, and their number can be set according to the strength requirements of the car roof. Generally speaking, the denser the number of through holes 31 and the smaller the through holes 31, the higher the strength. Furthermore, in other embodiments, an opening is provided on the side of the through hole 31 facing the interior of the car 10, and a transparent member is provided at the opening for sealing, so that a lighting fixture can be installed in the through hole 31, achieving illumination while concealing the lighting fixture.
[0031] In one embodiment, the rectangular plate has a thickness of at least 4 mm. Based on conventional material properties, it has been verified that when multiple elevator car roofs are assembled to seal the top of the car 10, setting the rectangular plate with the through-holes 31 formed therein to be at least 4 mm thick ensures that the car roof meets the strength requirements for supporting workers working on the car roof, thereby minimizing the weight of the car 10 while still meeting the supporting function.
[0032] In one embodiment, an anti-slip structure 32 is provided on the outer surface of the car top main body 30. When working on the car top, car top workers generally stand on the car top main body 30. Therefore, providing the anti-slip structure 32 on the outer surface of the car top main body 30 can effectively prevent car top workers from slipping on the car top, reducing operational risks.
[0033] In one embodiment, the anti-slip structure 32 is either an uneven pattern or spray-coated raised particles. The pattern can be dot-shaped, fish-scale, or grid-like. Raised particles are typically applied to the upper surface of the car top body 30 via spraying or coating, thereby preventing slipping and corrosion. Commonly used particles include sand, aluminum alloy, and mineral particles.
[0034] In one embodiment, the car roof frame structure 20 includes a connecting section fixedly connected to the inner wall of the car 10 and a supporting section extending from the connecting section toward the axis of the car 10. The connecting section and the supporting section are arranged perpendicular to each other and are integrally formed. The connecting section is attached to the inner wall of the car 10 and welded, or fixed to the inner wall of the car 10 via a connecting member, thereby supporting and fixing the car roof main body 30.
[0035] In one embodiment, a plurality of elevator car roofs are provided and arranged horizontally on top of the car 10, with the connecting sections between adjacent car roof frame structures 20 being fixedly connected. By providing multiple elevator car roofs to seal the top of the car 10, the connecting sections of the car roof frame structures 20 are utilized to enhance the support strength of the central portion of the car roof, thereby preventing the central portion from collapsing due to insufficient strength, which could result from being stepped on by workers.
[0036] The present application avoids the need to set reinforcing ribs by arranging a car top frame structure on the inner wall of the car top and forming a supporting plane inside the car top frame structure to support the car top main body, thereby simplifying the overall structure of the car top, reducing the overall weight of the car top, and helping to reduce the load on the traction system.
[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
