Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a casing structure for storing heavy objects, which is suitable for use in the casing of a control panel or a switchboard in which heavy objects such as transformers are housed.

[Prior art]

Switchboards and control panels that handle relatively large currents are housed within a designated casing. Various instruments and operation switches are placed on the front panel of the casing, and heavy items such as transformers are stored inside the casing. It is becoming more and more common. When moving this type of switchboard, etc., it is normal to either strongly reinforce the casing and move it with heavy items stored inside, or to remove the heavy items inside before moving. It was hot.

[Problem that the invention attempts to solve]

However, reinforcing the casing and temporarily removing heavy objects had the disadvantage of being uneconomical. There is also a method in which the heavy object inside the switchboard is lifted and the casing of the switchboard is supported by this heavy object, and the casing and the heavy object are lifted at the same time. This resulted in the problem of increased costs.

This invention was made in view of the above-mentioned circumstances, and relates to a casing structure for storing heavy objects that can be manufactured at low cost and is extremely easy to move.

[Means for solving problems]

In order to solve the above-mentioned problems, this idea
A casing for storing a heavy object inside the casing, a movable support member provided inside the casing so as to be movable up and down; a rod extending upward from the top of the movable support member and penetrating the upper surface of the casing so as to be movable up and down; A connecting member extending downward from the lower part of the movable support member and connecting to the upper part of the heavy object is provided.

[Effect]

With the above-described configuration, when the rod is lifted, the weight of the casing and the heavy object are applied only to the movable support member.

〔Example〕

Embodiments of this invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing the configuration of a switchboard that is an embodiment of this invention, and FIG.
-A line arrow view.

In these figures, 1 is a rectangular parallelepiped-shaped casing body, and a heavy object 2 such as a transformer is housed inside. 4, 4, ... are each the casing body 1
It is a rod that passes through the upper surface of the movable support member 5 so as to be vertically movable, and has a ring-shaped upper part and a lower end joined to the upper part of the movable support members 5, 5. The movable support members 5, 5 are members having a U-shaped cross section extending in the horizontal direction, and are configured to be vertically movable together with the rods 4, 4.... 6, 6... are locking members that penetrate the rods 4, 4... in the horizontal direction, and the vertical movement stroke length of the rod 4 and the movable support member 5 is the same as the upper end surface of the movable support member 5 and the locking member 6. It is equal to the distance from the bottom surface of . Further, L-shaped rods 8, 8, . . . extending downward are joined to the lower part of the movable support member 5. 10, 10... are arms for lifting that are joined to the upper surface of the heavy object 2, and the upper part is formed in a ring shape, and the above-mentioned rods 8, 8...
The lower end of the arm 10 is inserted into the upper part of the arm 10, 10.... Further, a horizontally protruding mounting portion is provided at the lower end of the heavy object 2, and this mounting portion is tightened to the bottom surface of the casing body 1 with bolts 11 and nuts 12. Note that the heavy object 2 and the casing body may be tightened by welding a nut to the bottom back surface of the casing body 1 and tightening a bolt passing through the mounting portion from above to this nut (so-called back nut method). Since the back nut method is generally superior in terms of workability, etc., the back nut method is mainly used except in special cases.

The states shown in FIGS. 1 and 2 show the configuration of the same embodiment in a stationary state. In this state, the movable support member 5 is supported by the support plates 9, 9 in a free state.
does not carry any weight.

Next, the case of lifting will be explained.
When lifting, first loosen the bolts 11 and nuts 12 so that the heavy object 2 can be moved upward. Next, the wires 15, 15 are placed over the tops of the rods 4, 4, and the rods 4, 4 are lifted upward. When the rods 4, 4 move upward, the weight of the heavy object 2 is applied to the movable support member 5 via the rods 8, 8..., the heavy object 2 is lifted, and the rods 4, 4... are moved upward. As the movable support member 5 is lifted up, the upper end surface of the movable support member 5 comes into contact with the upper surface of the casing body 1, whereby the casing body 1 is supported by the upper end surface of the movable support member 5 and lifted. In this case, the casing body 1 and the heavy object 2
The respective weights are applied only to the movable support member 5, and the weight of the heavy object 2 is applied to the casing body 1,
The weight of the casing body 1 is not applied to the heavy object 2, and therefore the casing body 1
Both of the heavy object 2 have sufficient strength to withstand their own weight, and no special reinforcement is required.

[Effect of idea]

As explained above, according to this invention, in a casing that stores a heavy object therein, a movable support member is provided inside the casing so as to be movable up and down, and a movable support member that extends upwardly from the upper part of the movable support member is attached to the casing. The rod is provided with a rod that penetrates the upper surface so as to be able to move up and down, and a connecting member that extends downward from the lower part of the movable support member and connects to the upper part of the heavy object, so that when the rod is lifted, the casing and the heavy object can be Both weights are applied to the movable support member, and as a result, both the casing and the heavy object have sufficient strength to withstand their own weight, and no special reinforcement or the like is required. Therefore,
It can be manufactured at extremely low cost. Furthermore, since there is no need to carry out heavy objects inside when lifting, there is an advantage that movement is extremely easy.
