Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a passenger conhair boarding and alighting device that is easy to process.

[Conventional technology]

FIG. 5 is a sectional view of a main part of a conventional passenger conveyor boarding and alighting device disclosed in, for example, Japanese Utility Model Application Publication No. 54-85692. In the same figure, the truss (■) is attached to a mechanical part (not shown) of the passenger conveyor, and is made strong with a thick L-shaped angle. Reference numeral 2 denotes jack bolts screwed into the upper part of the truss 1 as a support base, and a large number of jack bolts are arranged in parallel along the periphery of the landing area. 3 is a lock nut attached to the jack bolt 2; 4 is a platform floor plate supported by each jack bolt 2 as a support; 5 is an edge plate that surrounds the platform floor plate 4 and forms a border with the building floor. It is fixed to the truss 1 via a metal fitting 6.

In the passenger conveyor boarding and alighting device configured as described above, the boarding and alighting floor board 4 is installed in the following manner. First, the jack bolt 2 is screwed into a tapped hole provided in the truss 1, and adjusted so that its head is close to the upper end of the edge plate 5.

Next, place the platform floor plate 4 on the jack bolts 2,
Examine its flatness and stability. In other words, the platform floor plate 4
When the surface of the floor board 4 does not match the upper end of the edge plate 5, and when the heights of the jack bolts 2 are unstable due to unevenness, the landing floor plate 4 is removed and the height of the jack bolts 2 is readjusted. Then, again, the boarding area floor plate 4
Place it on jack bolt 2 and check the flatness and stability again.

By repeating such a procedure, the installation of the landing floor plate 4 is completed.

[Problem that the invention seeks to solve]

Conventional passenger conveyor boarding and alighting devices are constructed as described above, so it is necessary to machine screw holes in the thick truss for screwing in a large number of jack bolts, which makes machining extremely difficult. There are some problems.

The passenger conveyor boarding and alighting device according to the present invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a passenger conveyor boarding and alighting device that is easy to process.

[Means for solving problems]

In the passenger conveyor boarding and alighting device according to the present invention, a metal fitting thinner than the truss is fixed to the upper part of the truss, a threaded hole is formed in this metal fitting, and a jack bolt for supporting the boarding and alighting area floor board is attached to the metal fitting. .

[Effect]

In the passenger conveyor boarding and alighting device according to the present invention, a relatively thin metal fitting fixed to the upper part of a truss is provided with a tapped hole,
Since the jack bolts are screwed into these screw holes, the thinner wall thickness facilitates the machining work to provide a large number of tapped holes for screwing the jack bolts.

[Embodiments of the invention]

FIG. 1 is a sectional view of a main part showing an embodiment of a passenger conveyor boarding and alighting device according to the present invention, and the same parts as in FIG. 5 are indicated using the same symbols. In the figure, reference numeral 7 denotes a two-shaped metal fitting, which is made of a material that is sufficiently thin relative to the truss 1 and thick enough to provide sufficient strength to support the platform floor plate 4. One side of this metal fitting 7 is fixed to the upper surface of the truss 1, and a tapped hole is provided on the other side, into which the jack bolt 2 is screwed.

In the passenger conveyor boarding and alighting device configured in this way, the truss 1
Since the wall thickness of the metal fitting 7 is thinner than the wall thickness of the metal fitting 7, it becomes easier to form the counterbore.

Since the number of screw holes is large, the ease of machining greatly reduces the number of manufacturing steps, resulting in cost reduction.

FIG. 2 is a view corresponding to FIG. 1 showing the case where the jack bolt 2 is screwed upward from the bottom into the tapped hole formed in the metal fitting 7. In this case, there is a limit to reducing the height dimension due to the bending process of the metal fitting 7, but by screwing the jack bolt 2 upward, the dimension from the top surface of the truss 1 to the platform floor plate 4 can be reduced. It can be set as low as possible.

FIG. 3 shows a case where a U-shaped metal fitting 8 is used in place of the double-shaped metal fitting 7 shown in FIGS. 1 and 2, and the same effect can be obtained in this case as well. .

FIG. 4 is a side view of the passenger conveyor boarding and alighting device shown in FIG. 3, viewed from the edge plate 5 side. In FIG. 4, a window 9 for operating a spanner to turn the jack bolt 2 is provided in the part of the metal fitting 8 facing the jack bolt 2. In this case, the landing floor plate 4 is removed. It becomes possible to operate the jack bolt 2 from the side with a wrench without having to do so.

〔Effect of the invention〕

As explained above, according to the present invention, it is easy to drill holes for screwing in bolts.
This will greatly reduce the number of processing steps and reduce costs.

[Brief explanation of drawings]

FIG. 1 is a cross-sectional view of essential parts showing one embodiment of a passenger conveyor boarding and alighting device according to the present invention, FIGS. 2 to 4 are cross-sectional views and side views of main parts showing other embodiments, and FIG. 5 is a conventional one. FIG. 2 is a cross-sectional view of a main part showing a boarding and alighting device for a passenger conveyor. 1 is a truss, 2 is a jack bolt, 3 is a lock nut,
4 is the boarding area floorboard, 7 is the metal fittings. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.

Claims (1)

[Claims] In a boarding and alighting device that is provided at the entrance/exit portion of a running path of a passenger conveyor and supports a boarding and alighting floor plate through a jack bolt on the upper part of the truss, the boarding and alighting board is provided with a wall thickness of the truss that is thinner than that of the truss and the boarding and alighting area floor plate is attached to the truss. A method for boarding and disembarking a passenger conveyor, characterized in that a metal fitting made of a material with sufficient thickness for support is fixed, a screw hole for screwing in a jack bolt is provided in the metal fitting, and the jack bolt is screwed into the metal fitting. field equipment.
