Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to elevators, and more particularly to a work floor apparatus for installing an elevator.

[Prior art]

When installing an elevator, it is common practice to use the elevator floor as a work floor. In addition, there is a method in which a working floor is attached to an upper beam at the top of the car frame that supports the car floor, and the work floor is used for installation.

FIG. 1 is a perspective view illustrating a conventional method of installing an elevator using a work floor. Guide rails 2A and 2B are attached to the hoistway wall (not shown) via brackets LA and IB.
is supported and erected. A car floor 4 supported by a car frame 3 is arranged inside the guide rails 2A, 2B. An upper beam 5 crosses over the upper part of the car frame 3, and a working floor 6 is placed above the upper beam 5, which is strong enough to allow workers to work on the upper beam 5. . A notched groove is provided in the center of the work floor 6, and a lifting wire rope 7 suspends the upper beam 5 through this notched groove.

Conventional elevator advance work equipment that uses such a work floor 6 has the disadvantage that the work floor 6 must be manufactured separately depending on the dimensions of the hoistway and the shape of the elevator, resulting in high manufacturing costs. Ta. Furthermore, since the number of parts increases, there is a drawback that a great deal of effort is required for storage and management.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a work floor device for installing an elevator that has a highly versatile work floor that can be used for any hoistway size and elevator shape.

[Summary of the invention]

The present invention achieves the above object by providing a work floor with a structure that is expandable and retractable in the longitudinal direction of the elevator hoistway.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings, using the same reference numerals for the same parts as in the conventional example. FIG. 2 is a perspective view showing an embodiment of the elevator installation work floor device of the present invention. Guide rail 2A is attached to the hoistway wall (not shown) via brackets LA and IB'.

2B is supported and erected. This guide rail 2A, 2
A car floor 4 supported by a car frame 3 is arranged inside B. An upper beam 5 is provided with thorns on the upper part of the car frame 3, and above the upper beam 5, a main frame is installed that is strong enough to allow workers to work on the upper beam 5 and is designed to fit the minimum dimensions of an elevator. A work floor 6 is arranged. A notched groove is provided in the center of the work floor 6, and a lifting wire rope 7 suspends the upper beam 5 through the entire notched groove.

In this embodiment, an auxiliary work floor 8 is attached to the end of the main work floor 6 in the longitudinal direction of the hoistway, which is movable in the longitudinal direction of the hoistway and has a strength that allows workers to work thereon. This work floor 8 has brackets 9 that can be expanded and contracted in the longitudinal direction of the hoistway.
It is attached to and supported by bolts 15.

A support 10 is erected on the bracket 9, and a handrail 11 is supported by the support 10. A handrail bracket 12 is interposed in the middle of the handrail 11 to make the handrail 11 extendable and retractable in the longitudinal direction of the hoistway. are connected.

The main work floor 6, the auxiliary work floor 8, and the bracket 9 are supported by a bracket 14 having an L-shaped cross section as shown in FIG. 3, and the end of this bracket 14 is fastened to the upper beam 5. ing. The main work floor 6 is attached to a bracket 14 with attachment bolts 16.

Next, the operation of this embodiment will be explained. The main working floor 6 is manufactured to fit the smallest elevator shape, and the auxiliary working floor 8 and brackets 9 are normally attached to the main working floor 6.
The working floor consists of only the main working floor 6, which is the smallest in size. By the way, when the dimensions of the hoistway and the shape of the elevator become larger, the auxiliary work floor 8 and the brackets 9 are extended in the longitudinal direction of the hoistway according to the required dimensions, and a work floor of an appropriate size is connected to the main work floor 6 and the auxiliary work floor. The floor consists of 8 and 8 floors. At this time, the handrail 11 expands and contracts depending on the size of the work floor.

According to this embodiment, since the working floor is composed of the main working floor 6 and the expandable auxiliary working floor 8, the dimensions of the working floor can be adjusted regardless of the dimensions of the hoistway and the shape of the elevator. There is an effect that can be used by adapting.

Therefore, there is no need to manufacture a work floor every time depending on the dimensions of the hoistway and the shape of the elevator, which has the effect of significantly reducing the production cost. Furthermore, since the number of parts is small and the work floor can be standardized, there is also the effect of greatly reducing the labor involved in storing and managing parts.

〔Effect of the invention〕

As described above, according to the work floor device for elevator installation of the present invention, by making the work floor expandable and able to change its dimensions, it can be applied to any hoistway size and elevator shape. It is possible to provide a highly versatile work floor device for installing elevators.
