Description

TECHNICAL FIELD The present invention relates to an erecting and tilting device for erecting or tilting a heavy article such as a switchboard.

When installing a switchboard inside a building, in order to avoid passing through the door of the building or contacting low beams, the switchboard should be laid down and placed on a trolley and manually lifted near the installation location. It is standing and installed. However, a switchboard weighs 250 kg or more, and a large switchboard weighs about 400 kg. Since switchboards are mainly installed inside building rooms, crane trucks and the like cannot enter. Therefore, even now, standing up and leaning down by about 5 to 6 workers are the mainstream.

In response to this, conventionally, there has been proposed a device for mechanically erecting a switchboard. In Patent Document 1 (Utility Model Registration No. 3111744), a carriage that loads and transports a switchboard on its side is equipped with a carriage fixing frame that vertically raises the carriage, and the carriage is lifted to an angle α by a vertical screw screw, and then A switchboard transport and installation container is disclosed that stands vertically with horizontal screws.

Patent Document 2 (Japanese Patent Application Laid-Open No. 2012-218941) discloses a board fixing base supported by a movable carriage, a winch for raising the board fixing base, and a winch for tilting the board fixing base. A first rope for pulling the board fixing base backward is connected to the board fixing base, a second rope for pulling the board fixing base forward is connected to the tilting winch, and the first and second windings are performed. A control board erector is disclosed which erects the reels by rotating them together.

Patent Document 3 (Japanese Patent No. 006353316) discloses an article erecting device in which an article is erected when a first shaft moves along a floor from the lower surface of the article to the upper surface of the article while the article is lying on its side. is disclosed. The first axle is towed by a winch.

However, in the technique described in Patent Document 1, the truck and the truck fixing frame are integral structures, and the length of the truck fixing frame must exceed the switchboard, so there is a problem that the total length becomes long. As a result, it is difficult to load it in a one-box vehicle and bring it to the work site, move indoors, and walk up stairs.

In the technique described in Patent Document 2, the movable carriage must be longer than the switchboard, and there is a problem that the total length becomes long. In addition, it is necessary to lift and place the switchboard on the inclined board fixing base, and if there are enough people who can do this, it can be erected manually.

The technique described in Patent Document 3 is compact if it is only the device, but the length of the base and the winch stand is added to the length of the switchboard during standing work, so the total length during work becomes long. There is In addition, although the standing work can be performed, the tilting work of the removal board cannot be performed. In addition, although a damper is provided to reduce the impact when the article stands up, it is configured to reduce the impact after it occurs, and it can be said that it is insufficient as a countermeasure.

In the present specification and drawings, elements having substantially the same functions and configurations are denoted by the same reference numerals to omit redundant description, and elements that are not directly related to the present invention are omitted from the drawings. do.

FIG. 1 is a diagram for explaining the configuration of an upright tilting device 100 according to this embodiment. The standing and tilting device 100 is composed of a carriage 200 and a lifting device 300 which are separate bodies.

The carriage 200 is composed of a short floorboard 210 and a long backboard 220 . The width of the floor board 210 and the back board 220 may be the same, and they are L-shaped as a whole. A plastic sliding material is attached to the surfaces of the floor plate 210 and the back plate (inner surface of the L-shape).

Wheels 214 are attached to the rear surface of the floor plate 210 . Wheels 222 and 224 are attached to the rear surface of the back plate 220 . The wheels 222 are attached to the corners of the floor plate 210 and the back plate 220 and are shared as wheels for the bottom plate and wheels for the back plate. The back plate 220 has locking blocks 230 .

The lifting device 300 includes a gate-shaped traction-side support 310 having two posts and two lifting-side supports 320, for a total of four posts. A space between the two lifting-side struts 320 serves as a frontage for the carriage 200 to enter, and the traction-side struts 310 serve as a rear wall. The rear wall is the floor plate 210 side (tilting origin side) when the carriage 200 is tilted. A box-shaped side surface composed of a gate-shaped traction-side strut 310 and two lifting-side struts 320 is connected by a brace 330 and a front and rear beam 332 . The lifting-side supports 320 are connected by flat (thin) left and right beams 334 along the floor surface.

The elevation-side support pillar 320 is a hollow square member, and slits 322 that open vertically are formed on the inner surfaces facing each other. A lift block 324 is arranged in the lift-side column 320, and the inner surface of the lift-side column 320 guides the lift block 324 in the vertical direction.

A first reduction gear 340 is attached to the traction-side strut 310 . The first speed reducer 340 pulls a chain 346 as an example of a first cable via a gear shaft 344 . The chain 346 is turned downward by a sprocket 328 arranged at the inner upper end of the elevation-side column 320 to lift the elevation block 324 . The first speed reducer 340 has an input shaft 342 driven by a portable power tool such as an electric drill driver (hereinafter referred to as the power tool 20).

A protection device such as an acrylic cover may be attached to the side surface of the lifting device 300 . As a result, when the chain breaks, it is possible to prevent contact with the operator, and prevent the operator's hands and clothes from being caught in the chain.

In addition, a winch 350 as an example of a second speed reducer is attached to one of the towing-side struts 310, and a wire as an example of a second cord is attached between a hook 354 provided on the other column. 356 is handed over. A movable pulley 358 is attached to the wire 356 and connects to the U-shaped fitting 216 of the floor plate 210 of the truck. Therefore, the winch 350 can pull the wire 356 toward the traction-side strut 310 or loosen it and let it out. The winch 350 also has an input shaft 352 to which driving input from the power tool 20 is applied, similar to the first speed reducer 340 .

The lifting device 300 can be disassembled into parts (pillars and beams), stored and transported, assembled at a work site, and used. A prototype made of steel for each member had a weight of about 250 kg after assembly, a total height of 1600 mm, and a width of 1040 mm. Further weight reduction can be achieved by using an aluminum alloy instead of steel for all or part of each member.

Next, referring to FIGS. 2 to 8, the setup for erecting the switchboard will be described. As shown in FIG. 2, first, the truck 200 is laid down with the back plate 220 facing the ground. Then, the switchboard 10 is placed on the back plate 220 of the truck 200 . Since this work can be performed outdoors, the switchboard 10 can be placed using a crane (not shown) or the like. By attaching a sliding member to the surface of the back plate 220, it is easy to shift the switchboard 10 to adjust its position.

Then, as shown in FIG. 3, the carriage 200 is driven by the wheels 222 and 224 and entered between the two lifting-side supports 320 with the floor board 210 as the head. It is preferable that the truck 200 and the switchboard 10 are fastened with a belt 12 so as not to shift.

As shown in FIG. 4, once the carriage 200 is advanced to align the hole 326 of the lifting block 324 with the hole 232 of the locking block 230, the pipe 360 is inserted. Thereby, the locking block 230 and the lifting block 324 are rotatably connected. In this embodiment, the blocks 230 and 324 are connected to the pipe 360, but they may be rotatably connected using a chain and a hook.

Next, as shown in FIG. 5, the switchboard 10 starts to stand up. First, the movable pulley 358 towed by the winch 350 is connected to the U-shaped fitting 216 of the floor plate 210 of the truck. Then, the driving force is input from the input shaft 342 to the first reduction gear 340 by the power tool 20 to pull the two chains 346 through the gear shaft 344 . Then, the sprocket 328 changes the pulling direction of the chain 346 upward from the lateral direction from the traction-side strut 310 to the lifting-side strut 320 and pulls up the lifting block 324 . Then, since the elevating block 324 and the locking block 230 are connected, the back plate 220 of the truck 200 is lifted, and the upper part of the switchboard 10 is lifted obliquely. It should be noted that the position of the locking block 230 must be on the upper side of the switchboard 10 relative to the center of gravity of the switchboard 10 .

As shown in FIG. 6, as the hoisting of the chain 346 by the first speed reducer 340 progresses, the switchboard 10 progresses to stand up. Since the wires 356 are connected to the U-shaped fittings 216 of the floorboard 210 of the truck, the floorboard 210 cannot approach the floor. When the elevating block 324 is further raised to move the center of gravity of the switchboard 10 and the truck 200 to the side of the floor plate 210 rather than the wheels 222, the first reduction gear 340 is stopped. At this time, the switchboard 10 is obliquely suspended by the pipe 360 and the wire 356 . Depending on the gear ratios of the first speed reducer 340 and the winch 350 , the load of the switchboard 10 can be supported by the chain 346 and the wire 356 even when the power tool 20 is removed from the input shafts 342 and 352 .

Then, as shown in FIG. 7, the input shaft 352 of the winch 350 is rotated by the power tool 20 to let out and loosen the wire 356 . Then, the floor plate 210 descends toward the floor, and the switchboard 10 stands up. Since the switchboard 10 can be gradually erected in this manner, no impact is generated when the switchboard 10 is erected, and the switchboard 10 does not fall to the opposite side due to momentum.

As shown in FIG. 8, when the switchboard 10 is erected, the movable pulley 358 is removed from the U-shaped fitting 216 . Also, the pipe 360 is pulled out to release the connection between the lifting block 324 and the locking block 230 . Then, the cart 200 becomes free and can be separated from the lifting device 300. - 特許庁

9 and 10 are diagrams for explaining the setup for installing the switchboard 10. FIG. It is assumed that the switchboard 10 is fixedly installed on rails 30 installed on the floor. The existing switchboards 10 are lined up on the rail 30, and the new switchboard 10 is installed on the empty rail 30 next to it.

As shown in FIG. 9, the switchboard 10 is moved to the installation location by a truck 200, but the newly installed switchboard 10 and the existing switchboard 10 have protrusions such as switches, so they cannot be brought very close. It is also difficult to move the truck 200 carrying the very heavy switchboard 10 along the rails 30 without gaps.

Therefore, in this embodiment, a remounting base 400 that moves the switchboard 10 from the carriage 200 to the rail 30 is used. The transfer table 400 has a sliding member attached to the upper surface of the floor panel 410 . Height adjusting bolts 420 are attached to four sides of the transfer table 400 .

Then, as shown in FIG. 10, the switchboard 10 is pushed and pulled to move it onto the rails 30 while the floor plate 210 of the truck, the transfer table 400 and the rails 30 are arranged without gaps. This completes the installation of the switchboard 10 .

When the switchboard 10 is to be removed, the switchboard 10 can be tilted sideways by performing the above steps in reverse order. That is, after pulling the wire 356 to lift the floor plate 210 of the truck 200, the chain 346 is let out to lower the pipe 360, whereby the switchboard 10 can be gradually tilted.

As described above, according to the erecting and tilting device of the present invention, the work of erecting and installing a switchboard, removing the switchboard, laying it down and carrying it out can be carried out safely and with good quality by a small number of people. Moreover, since the structure is simple, special training is not required, and it is easy to install and handle. In addition, since the body of the carriage 200 and the lifting device 300 is composed of columns and braces, the overall weight can be reduced.

Moreover, since the structure is such that the switchboard 10 stands up by lifting the pipe 360 instead of the switchboard 10 being suspended from above, the overall height of the device can be reduced and the size can be reduced. can also be applied.

In addition, since the cart 200 and the lifting device 300 are separate units and can be easily disassembled and assembled, they can be loaded onto a one-box truck and brought to the work site, and two people can move indoors and walk up stairs. It is possible.

In the above embodiment, the switchboard is used as an example of an article to be raised and tilted, but the present invention is not limited to the switchboard. It can also be used for various articles (eg, tanks, containers, etc.) that are carried into a building on its side and erected indoors.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is obvious that a person skilled in the art can conceive of various modifications or modifications within the scope described in the claims, and these also belong to the technical scope of the present invention. Understood.
