Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a storage floor, and more particularly to improvement of a corridor used for operation and inspection of equipment valves in plant equipment and the like.

[Conventional technology]

Conventionally, a corridor for operation and inspection of equipment valves in plant equipment and the like has an integrated structure without distinguishing a main corridor and an auxiliary corridor, and has a structure in which a floor height of the corridor is changed as necessary. In other words, the corridor that is surrounded by various equipment is designed so that it is easy for workers to inspect it according to the height of the inspection port. I was dealing with it by changing the floor to make it higher.

[Problems to be solved by the device]

However, in the above-mentioned conventional corridor equipment, not only the corridors of different heights hinder the passage, but this structure also complicates the structure of this corridor, which causes problems in safety and cost. It was

The present invention focuses on the above-mentioned conventional problems, and an object thereof is to provide a storage floor that allows safe and easy operation and inspection of equipment valves and does not cause a passage obstacle.

[Means for Solving the Problems]

In order to achieve the above object, the storage floor according to the present invention has an auxiliary floor that is pivotally attached at one end to the handrail side of the main corridor and can be lifted and lowered between the main corridor floor surface and the handrail surface. The feeding end portion of the auxiliary floor is provided with a rotatably pivoted leg portion, and a hook is provided which can be engaged with the handrail of the main corridor by jumping up the auxiliary floor.

[Action]

According to the above configuration, the auxiliary floor can be stored in advance by using the hooks along the handrail surface of the main corridor, and at this time, there is no step in the main corridor. Therefore, the worker can pass through the passage without hindrance. Then, if necessary, remove the hook from the handrail, lower the auxiliary floor, and at the same time pull out the storage leg from the end of the auxiliary floor, and abut this leg on the floor surface of the main corridor. It will be installed higher than the floor. As a result, the worker can ride on the auxiliary floor and perform work such as inspection at a high place.

〔Example〕

Hereinafter, a specific embodiment of a storage floor according to the present invention will be described in detail with reference to the drawings.

1 to 3 show the storage floor of the embodiment. As shown in these figures, the main corridor 10 circulates a floor frame 14 on which a grating 12 constituting a floor surface is placed along a walking line, and two parallel handrails 16 are provided on one side edge of the floor frame 14. It is provided via 18. Such a main corridor 1
The storage floor 20 according to the embodiment is provided at a predetermined position of 0 so that the worker can ride and work at a position higher than the grating 12.

First, a gate-shaped fixed leg 22 that is erected parallel to the handrail surface is installed on the floor frame 14 directly below the handrail 16, and its upper beam is connected to and integrated with the lower handrail 16. The fixed leg 22 serves as an installation frame for the storage floor, and the grating 12 and an auxiliary floor 24 installed with a step are attached to the fixed leg 22. Therefore, one end side surface of the auxiliary floor 24 is connected to the inner surface of the fixed leg 22 at an upper position of the leg portion by a fixed pivot pin 26, and the auxiliary floor 24 can be elevated about the fixed pivot pin 26. There is. Therefore, the auxiliary floor 24 can take two positions at least above the grating 12 and parallel to it by the turning operation, and a position along the surface of the handrail 16. In this case, the fixed legs 22 are arranged so that the auxiliary floor 24 can be parallel to the surface of the handrail 16.
The upper beam side above the position of the fixed pivot pin 26 is bent backward so that the upper beam does not interfere with the turning of the auxiliary floor 24 and the leg portions of the auxiliary floor 24 and the fixed leg 22 can be flush with each other. I have to.

Further, leg portions 28 for supporting the space between the auxiliary floor 24 and the grating 12 are attached to the lower end surfaces of both ends of the auxiliary floor 24. The leg portion 28 is attached to the auxiliary floor 24 through a connecting pin 30 so that the leg portion 28 can be turned from a position parallel to the auxiliary floor 24 to a position orthogonal to the auxiliary floor 24. This connecting pin 30 is an auxiliary floor 24
It also serves as the takeout pin of the
Are projected from the side surface of the auxiliary floor 24. Also, the leg 2
8 can be accommodated in the auxiliary floor 24 when not in use, so that the lower end of the leg portion 28 has a fitting hole 3
2 is formed, and a leg fixing pin 34 is provided on the side surface of the leg 28 on the rotation locus of the fitting hole 32, and the leg fixing pin 34 is mounted in the fitting hole 32 when the housing 28 is housed. It is designed to be fixed and held.

In addition, an engaging hook 36 is provided on the tip side surface of the auxiliary floor 24 so that the auxiliary floor 24 can be connected and held by the handrail 16 during storage.
Is attached and the auxiliary floor 24 is lifted up to move the handrail 1
It can be engaged with the upper handrail 16 when it is arranged in parallel with the six surfaces. A side plate 38 is provided at the leading edge of the auxiliary floor 24.

It should be noted that the storage floor may be set to a height corresponding to one step of the stair-stepping plate, but if a height of two steps or more is required, a trap or the like may be provided on the auxiliary floor 24. This can be easily dealt with by pivotally attaching a simple trap to the tip edge of the auxiliary floor 24.

The operation of the storage floor configured in this way is as follows.
When the storage floor is pulled out, as shown in FIGS. 2 to 3, the auxiliary floor 24 is supported by a fixed pivot pin 26 that is a connecting portion with the fixed leg 22, and the tip side is held by a leg portion 28. Therefore, the auxiliary floor 24 is in a horizontal state as a whole,
A walkway at a position higher than the grating 12 is formed. Then, when the work on the auxiliary floor 24 is completed, the tip of the auxiliary floor 24 is lifted, the leg portion 28 is tilted to the rear surface side of the auxiliary floor 24, and the leg fixing pin 3 is inserted into the fitting hole 32.
Insert 4 and try to accommodate it. Then, the entire auxiliary floor 24 is lifted up around the fixed pivot pin 26,
The engaging hook 36 on the side surface of the handrail is engaged with and fixed to the upper handrail 16, and the storage floor is stored on the handrail 16 side. In such a case, the auxiliary floor 24 and the legs 28 are both stored in the same plane as the handrail 16 and are stored.
In this case, there are no obstacles such as the auxiliary floor 24. Therefore, the worker can walk the stepless grating 12 of the main corridor 10, and the safety is improved.

Thus, according to this embodiment, the auxiliary floor 2
4 can be turned upside down to form or store the auxiliary floor 24, and the walking safety and the simple structure of the walkway can be achieved. Further, there is also an advantage that the storage floor can be installed at an arbitrary place of the existing or newly installed main corridor 10 according to the purpose of use.

[Effect of device]

As described above, according to the present invention, the auxiliary floor can be arranged parallel to the handrail side, and when used, it can be pulled out to form the auxiliary floor at a position higher than the floor surface height of the main corridor. There is no need to make a step in the floor height of the corridor, and it is possible to secure the walking safety of the main corridor and it is possible to form a high corridor part without complicating the structure of the corridor. .
