Detailed Description

Other advantages and capabilities of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification by describing specific embodiments of the present invention with reference to the attached drawings. In the following description, specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced or applied in different embodiments, and the details may be based on different viewpoints and applications, and may be widely spread and replaced by those skilled in the art without departing from the spirit of the present invention.

Example 1

As shown in fig. 1, the elevator car roof provided by this embodiment includes:

the lower layer ceiling framework 1 and the upper layer car top framework 2 are fixedly connected, and the lower layer ceiling framework 1 and the upper layer car top framework 2 are fixedly connected with a car wall 5 of an elevator car;

the lower layer of ceiling framework 1 is provided with at least one ceiling opening (not shown in the figure), the upper layer of ceiling framework 2 is provided with at least one ceiling opening (not shown in the figure), the projections of the ceiling opening and the ceiling opening in the vertical direction are provided with an overlapping area, and the space of the overlapping area can be passed by maintenance personnel;

the elevator car roof also comprises a decoration part 3, wherein the decoration part 3 is fixed on the lower layer ceiling framework 1 in an openable mode and covers the opening hole of the ceiling;

the elevator car top further comprises a car top cover plate 4, wherein the car top cover plate 4 is fixed on the upper-layer car top frame 2 in an openable mode and covers the car top opening.

And the car top cover plate 4 is positioned at the upper part of the upper-layer car top frame 2 after being opened. The car roof cover plate is opened in a translation or turnover mode.

The decorative member 3 includes, but is not limited to, a lighting panel, a decorative panel, a light guide plate, or the like. The trim part 3 is fixed to the lower ceiling frame 1 at ordinary times and is detachable when required for maintenance. The decoration part 3 can also be clamped on the lower layer ceiling framework 1 through a clamp spring and can be pulled open to be removed when needing to be overhauled. The decoration part 3 can be fixed with the lower layer ceiling framework 1 through bolts, bolts and other modes, and can be detached and taken down after the fixing part is required to be overhauled. After removing decoration part 3 on the furred ceiling frame 1 of lower floor, expose the furred ceiling trompil, staff's accessible furred ceiling trompil opens cab apron 4, exposes the sedan-chair top trompil, can overhaul the part in sedan-chair top and the elevator well. The car roof cover plate 4 can be opened, fixed and detached to move in modes of clamp springs, bolts and the like.

Example 2

As shown in fig. 2, in the embodiment 1, the decorative member 3 is fixed to the lower ceiling frame 1 in a hinged manner, and can be turned downward along the lower ceiling frame 1.

During the disassembly of the trim part 3, there is a possibility that the trim part will fall if it is mishandled. During normal use, the elevator will also deviate from its original position due to vibrations and the like. Generally, the decorative part 3 is added with a device for preventing falling off, such as a clamping piece, a lifting rope and the like. But when dismantling the maintenance, need take off anti-drop's device, if do not have the recovery after the maintenance completion and can have the potential safety hazard. And thus may be attached to the lower ceiling framework 1 by hinges 6 at one side of the trim part 3 and by latches, bolts or other means at the other end.
