[0025] The following describes the implementation methods of the present invention through specific specific embodiments, and those skilled in the art can fully understand other advantages and technical effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through different specific implementation methods, and the details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without deviating from the overall design concept of the invention. It should be noted that the following embodiments and the features in the embodiments can be combined with each other in the absence of conflict. The following exemplary embodiments of the present invention can be implemented in a variety of different forms and should not be interpreted as being limited to the specific embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides an elevator car top platform, including a car top plate 1, a car top footboard 2, a bolt assembly 3, a shock absorber mounting seat 4, a ventilation hole 5, a door machine mounting seat 6, a transverse C-shaped channel steel 7, a longitudinal C-shaped channel steel 8, a stop connector 9, a wiring trough cover plate 10, a wiring trough 11, a car top station mounting seat 12, a car top guardrail 13, a fan 14, a shock absorber 15 and a car top shield 16, and other components that need to be connected to the car top.

[0028] The transverse C-shaped channel steel 7 is fixed at the front and rear of the car top plate 1, and the direction of the transverse C-shaped channel steel 7 is parallel to the car door after being fixed; the longitudinal C-shaped channel steel 8 is fixed at both sides of the car top plate 1, and the direction of the transverse C-shaped channel steel 8 is perpendicular to the car door after being fixed; the transverse C-shaped channel steel 7 and the longitudinal C-shaped channel steel 8 are used as installation bases for components that need to be connected to the car top.

[0029] The car top plate 1 is a complete and undivided plate. A rivet nut hole is opened in the outermost flange of the car top plate 1. The rivet nut is pre-installed before leaving the factory. The car top footboard 2 can be connected and fixed with the bolt assembly 3 on site. The same interface can be connected to the car top footboard 2 or the car top shield 16. The two will not be configured at the same time. The shared interface reduces the workload of drawings. Figure 1 As shown in the enlarged view at point A in the middle, the car top panel flange on the side where the door machine is installed is lower than the car top panel flanges on both sides. When the span of the door machine installation arm changes, there is no need to consider whether the bolt head for installing the entrance and exit upper plate interferes with the door machine mounting seat, which reduces the design workload and improves manufacturing efficiency.

[0030] The transverse C-shaped channel steel 7, the longitudinal C-shaped channel steel 8 and the wiring trough 11 are all welded and fixed to specific positions of the car top plate 1. For example, in this embodiment, the longitudinal C-shaped channel steel 8 runs through the entire car top plate 1, and the transverse C-shaped channel steel 7 is located between the longitudinal C-shaped channel steels 8 on both sides. The wiring trough 11 is located between the front transverse C-shaped channel steel and the rear transverse C-shaped channel steel.

[0031] The shock absorber mounting seat 4 is respectively welded and fixed to the car top plate 1 and the longitudinal C-shaped channel steel 8. Any position of the C-shaped channel steel can be used in conjunction with the stop connector 9. When the specifications of the components to be connected to the car top, such as the door machine mounting seat 6, the car top station mounting seat 12 and the car top guardrail 13, are changed, the connection position can be changed through the slide groove without additional holes, which reduces the design workload and improves the manufacturing efficiency.

[0032] The stop connector 9 comprises bolts, washers and nuts that fix a square plate, and its function is that the stop connector 9 can slide to any position in the C-shaped channel steel, and can stop rotation when the nut is tightened, and fix the components connected to the car top.

[0033] A ventilation hole 5 is opened in the car top plate 1 below the shock absorber mounting seat 4 to meet the national standard requirements for the ventilation area in the car. The shock absorber mounting seat 4 also serves to connect the shock absorber, shield the ventilation hole from light, and prevent foreign objects from falling. The shock absorber mounting seat 4 is welded to the car top plate 1 and the longitudinal C-shaped channel steel 8 to enhance the strength of the car top.

[0034] The wiring trough 11 is welded on the car top plate 1, which serves as a reinforcing rib to improve the strength of the car top and hides the wiring to beautify the car top. The wiring trough cover plate 10 is bonded and fixed with a magnetic strip. When the wires are neatly bundled and put into the wiring trough, the wiring trough cover plate 10 is directly magnetically attracted to the wiring trough to prevent the cover plate 10 from shaking and reduce the installation workload.

[0035] like Figure 2 As shown, the car top shield 16 includes side panels and cover panels. The side panels are first fixed on the car top panels to form an enclosed wall, and the cover panels are fixed on the side panels. When people go up to the car top for inspection, they take out the three upper cover panels and stand on the car top to operate, which provides a safer operating space for maintenance. After the inspection is completed, first fix the cover panel away from the door machine with bolts, then press the flange of the middle cover panel under the first cover panel and tighten two bolts, then retreat to the floor station and tighten the last cover panel. The advantage of this design is that the sightseeing elevator can cover the car top components, which is more beautiful. The design of the cover panel reduces the number of fixings and is more convenient for inspection and operation, and the surrounding walls are safer.

[0036] Example 2

[0037] The elevator car top platform of this embodiment is generally similar to that of the embodiment 1. The difference is that the transverse C-shaped channel steel 7 runs through the entire car top plate 1, and the longitudinal C-shaped channel steel 8 is located between the transverse C-shaped channel steels 7 at the front and rear of the car top plate. The fan 14 is moved to the middle of the two front transverse C-shaped channel steels 7, and the longitudinal C-shaped channel steel 8 is shortened through the transverse C-shaped channel steel 7 to meet the demand for a wider span of the door machine. At the same time, the shock absorber 15 and the shock absorber mounting seat are installed on the longitudinal C-shaped channel steel 8 to reduce the number of components.

[0038] The present invention has been described in detail above through specific implementation modes and embodiments, but these do not constitute limitations of the present invention. Without departing from the principles of the present invention, those skilled in the art may also make many variations and improvements, which should also be regarded as the protection scope of the present invention.
