Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electrical equipment moving device that is used when there is a restriction on the installation location of the electrical equipment and a heavy electrical equipment is moved to the installation location.

[Conventional technology]

Generally, with heavy electrical equipment such as underground switches, it may be extremely difficult to move the equipment due to the conditions of the location where it is installed. However, it is necessary to move the electrical equipment to a predetermined installation location.

As a conventional moving device for electrical equipment,
For example, there is a mobile device disclosed in Japanese Utility Model Application Publication No. 56-15213.

Next, this moving device will be explained with reference to FIG.

Mounts 2 are attached to the front and rear of the bottom of the electrical equipment 1, bosses 3 are fixed to both ends of each mount 2, and support rods 4 are screwed to the bosses 3, respectively.

Furthermore, disk-shaped support seats 5 are welded to the lower surface of the pedestal 2 adjacent to the support rods 4, respectively. On the other hand, a pair of support plates 8 are attached to the base 7, and a roller-shaped wheel 6 is rotatably supported by both support plates 8.

Then, a bolt is installed in the center of each mounting seat 5, and the bolt is guided downward through the base 7. A nut is screwed onto the drawn-out bolt from below to tighten it, and then the bolt 9 is tightened. It is fastened to the mounting seat 5 via the base 7, and the base 7 is attached to each mounting seat 5, respectively.

Then, in the state shown in FIG. 1, after moving the electrical equipment 1 to a predetermined position, the support rod 4 is rotated and lowered to bring its tip into contact with the floor, and by further rotation, the pedestal 2 is moved. Floating to the top, wheel 6
is removed from the floor surface, and the electrical equipment 1 can be fixed.

Here, when changing the direction of the wheel 6,
With the wheel lifted off the floor, loosen the nut at the center of the wheel 6 and remove the bolt 9.
After rotating the base 7 by a predetermined angle with respect to the mounting seat 5,
The base 7 is fixed to the mounting seat 5 with bolts 9 and the nuts.

[Problem that the invention attempts to solve]

However, according to the conventional moving device, when moving and fixing the electric device 1, it is necessary to operate the bolt 9 and the nut from below the pedestal 2, which is extremely inefficient.

Furthermore, move the electrical equipment 1 forward, backward, left and right, and diagonally.
Although it is possible to move in any direction,
When the electric device 1 cannot be moved in the rotational direction and the direction of movement of the electric device 1 is changed, it is necessary to change the direction of the wheels 6 each time.

Furthermore, since the direction of the wheels 6 must be changed, it is necessary to attach the base 7 to the disk-shaped mounting seat 5, which has the disadvantage of increasing the installation space.
Conventional mobile devices have the disadvantage that they are difficult to apply to limited installation locations such as underground locations.

[Means for solving problems]

This invention was made with the above points in mind, and includes a pedestal attached to the bottom of an electrical device, and a support plate mounted on the top surface of the pedestal at a position distant from the bottom mounting surface of the electrical device. a support plate that is applied from above to the support plate mounting surface; and a support plate that is attached to the lower surface of the support plate, and the length from the lower surface of the support plate to the lowest surface is the distance between the support plate mounting surface and the lower end of the pedestal. a plurality of casters that are longer than the length of the support plate and can be freely changed in direction; a nut provided on the lower side of the mounting surface of the mount; and a nut extending from above the support plate and passing through the support plate and the support plate mounting surface. The apparatus for moving electrical equipment includes a bolt that is inserted and screwed into the nut to removably fix the support plate to the pedestal.

[Effect]

Therefore, according to this invention, the electrical equipment can be moved and fixed by operating the bolts from above, resulting in extremely good workability.

Furthermore, since casters that can freely change direction are used, the direction can be changed freely, and a large space is not required.

〔Example〕

Next, this invention will be explained in detail with reference to the drawings from FIG. 2 onwards showing an embodiment thereof.

First, FIGS. 2 to 4 showing one embodiment will be explained.

In these drawings, 10 is an electrical device such as an underground switch, 11 is a bottom plate of the electrical device 10, and 12 is an inverted U-shaped cross section that is long in the front-rear direction and is attached to the bottom surface of the bottom plate 11 with a fixing bolt 13 from above. 2
The front and rear ends thereof are each formed in such a length that they protrude forward and backward from the front and rear edges of the bottom plate 11.
A support plate mounting surface is formed on the upper surface of the protrusion from the bottom plate 11 of both mounts 12, that is, on the upper surface of a position spaced apart from the bottom of the electrical device 10.

14 is a support plate applied from above to the mounting surface, and each support plate 14 is connected to the support plate 14 and both mounts 1.
Install bolts 1 from above into the bolt holes of 2 and 2 respectively.
5 and is fixed by tightening it to a nut 16 fixed to the lower side of the mounting surface.

Reference numeral 17 denotes a mounting seat having a U-shaped cross section fixed by welding to both sides of both mounts 12 on the lower surface of the support plate 14, and 18 a ball caster fixed to the lower surface of each mounting seat 17, which can freely change direction. ,
The length from the lower surface of the present invention 14 to the lowest surface of the ball 19 of the ball caster 18 is slightly longer than the length between the lower surface of the support plate 14, that is, the mounting surface and the lower end of the pedestal 12. Note that the support plate 14, the mounting seat 17, and the pole caster 18 constitute a truck 20 of the moving device.

When moving the electrical device 10 installed on the floor, the cart 20 is placed at the front and rear ends of the pedestal 12, and the mounting bolts 15 are inserted into the respective bolt holes of the support plate 14 and the pedestal 12 from above. and screw it into the nut 16 on the lower side of the mounting surface of the frame 12,
Tighten the mounting bolt 15.

At this initial stage of tightening, there is a gap between the mounting surface of the pedestal 12 and the lower surface of the support plate 14;
As the mounting bolts 15 are tightened, the gap narrows, and the pedestal 12 tightens between the mounting bolts 15 and the support plate 14.
The electrical equipment 10 is lifted off the floor and supported by each ball caster 18 of both carts 20, and is in the state shown in FIGS. 2 to 4. Here, since the ball caster 18 is freely changeable in direction, the electric device 10 can be moved in any direction.

Further, when installing the electrical device 10 that has been moved to a predetermined position, when the mounting bolt 15 is loosened, the pedestal 12 moves downward due to the weight of the electrical device 10, and the pedestal 12 comes into contact with the floor surface. Then, the mounting bolts 15 are removed, the trolley 20 is removed, the pedestal 12 is fixed to the floor with foundation bolts, etc., and the electrical equipment 10 is fixed.

Therefore, according to the embodiment, by using the ball casters 18 as the wheels of the trolley 20, it is possible to move the electrical equipment 10 in any direction, and unlike the conventional case, the direction of the wheels is changed every time the direction of movement is changed. There is no need to change the position, and it is possible to move in narrow, limited places such as underground, and to make fine adjustments at the installation position, and it can be moved extremely easily by a small number of people.

Furthermore, the electrical equipment 10 can be lifted off the floor at the same time as the trolley 20 is attached to the electrical equipment 10 using the mounting bolts 15, and when the trolley 20 is attached or removed, the mounting bolts 15 are tightened or loosened from above. Therefore, workability is improved and the carriage 20 can be easily attached and detached.

Furthermore, by using the ball caster 18, the trolley 20 can be made compact, and a large amount of space is not required for attaching and removing the trolley 20, so that it can be used even when there are restrictions on the installation location.

Here, by attaching a large number of ball casters 18 to the cart 20, it is possible to make the cart 20 less susceptible to the effects of unevenness on the floor surface.

Next, the drawings from FIG. 5 onwards showing other embodiments will be explained.

In this embodiment, the electrical equipment is raised considerably from the floor, making it easier to operate the electrical equipment. In these drawings, the same symbols as above indicate the same or corresponding items, and the differences are as follows: The pedestal 21 of the electrical equipment 10' is formed into a frame shape using an angle, and the support plate 14 of the trolley 20 is attached between the opposing lower sides 21' of the pedestal 21.

That is, auxiliary angles 22 are welded to both ends of the opposing lower sides 21' of the pedestal 21 to form a horizontal mounting surface, and the support plate 14 is mounted on the mounting surface using mounting bolts 15 and nuts 16. Note that the length from the bottom surface of the support plate 14 to the bottom surface of the ball 19 of the ball caster 18 is the same as that of the mount 2.
1 to the mounting surface of the auxiliary angle 22.

Further, the nut 16 is integrally provided with a shaft for preventing rotation on its side surface, and the nut 16 is guided to the lower surface of the auxiliary angle 22 using the shaft, and is screwed into the mounting bolt 15. here,
The nut 16 may be fixed to the lower surface of the auxiliary angle 22.

Therefore, as described above, the trolley 20 can be easily attached to and removed from the electrical equipment 10'.
This not only improves work efficiency, but also allows the electric device 10' to be moved in any direction, and provides the same effects as described above.

In the above embodiment, the ball caster 18 is attached to the support plate 14 to constitute the truck 20, but a flexible caster may be used instead of the ball caster 18.

Furthermore, the shape of the pedestal in this invention is
It goes without saying that the cross section is not limited to the inverted U-shaped cross section of the second embodiment and the angular frame shape of the second embodiment, but that other shapes may also be used. The surface may be located at a position distant from the bottom of the electrical device, and the position of the mounting surface is not limited.

[Effect of idea]

As described above, according to the electrical equipment moving device of this invention, the electrical equipment 1, 10' can be moved and fixed by operating from above the mounting bolt 15, so that the workability is extremely good.

Furthermore, since casters that can change direction are used, the electrical equipment can be moved in any direction, and even if there are restrictions on the installation location, it can be accommodated sufficiently and does not require a large space.
