Description

[Technical Field]

[0001] The present invention relates to an erecting and tilting device for erecting or tilting a heavy object such as a distribution board. [Background technology]

[0002] When installing a distribution board inside a building, to avoid people walking through building doors or coming into contact with low beams, the distribution board is placed in a tilted position on a cart and manually transported, and then manually erected and installed near the installation location. However, distribution boards weigh over 250 kg, and larger ones can weigh around 400 kg. Since distribution boards are mainly installed inside buildings, cranes and other vehicles cannot enter. For this reason, manual erection and tilting by around 5 to 6 workers is still the norm.

[0003] In response to this, devices for mechanically erecting switchboards have been proposed.Patent Document 1 (Utility Model Registration No. 3111744) discloses a container for transporting and installing switchboards, which includes a carrier that transports a switchboard sideways and is equipped with a cart fixing frame that erects the carrier vertically, and which uses a vertical screw to lift the carrier to an angle α, and then uses a horizontal screw to erect the carrier vertically.

[0004] Patent Document 2 (JP 2012-218941 A) discloses a control panel erecting device that includes a panel fixing base supported by a mobile carriage, an erecting winch for the panel fixing base, and a tilting winch for the panel fixing base, the erecting winch connecting a first rope to the panel fixing base that pulls the panel fixing base backward, and the tilting winch connecting a second rope to the panel fixing base that pulls the panel fixing base forward, and that erects the panel by rotating the first and second winding reels together.

[0005] Patent Document 3 (Patent Publication No. 006353316) discloses an article erecting device in which, when an article is lying on its side, a first shaft moves along the floor surface from the bottom to the top of the article, causing the article to stand up. The first shaft is pulled by a winch. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility Model Registration No. 3111744 [Patent Document 2] Japanese Patent Application Laid-Open No. 2012-218941 [Patent Document 3] Patent No. 006353316 (JP Patent Publication No. 2016-039765) U.S. Patent No. 9753461 Summary of the Invention [Problem to be solved by the invention]

[0007] However, with the technology described in Patent Document 1, the carriage and carriage fixing frame are an integrated structure, and the carriage fixing frame must be longer than the switchboard, which results in a problem of a long overall length, which makes it difficult to load into a minivan and bring to a work site, move indoors, or negotiate stairs.

[0008] The technology described in Patent Document 2 also has the problem that the mobile cart must be longer than the switchboard, resulting in a long overall length. Also, the switchboard must be lifted and placed on an inclined panel fixing stand, and if there are enough people to do this, it can be erected manually in the first place.

[0009] The technology described in Patent Document 3 is compact when it is just the device, but when erecting the equipment, the length of the base and winch stand are added to the length of the distribution board, resulting in a problem of a long overall length during the operation. Furthermore, while erection is possible, tilting of the removal board is not possible. Furthermore, although a damper is provided to absorb the impact when the item is erected, this is only configured to absorb the impact after it has occurred, and this is an insufficient solution.

[0010] Therefore, an object of the present invention is to provide an erection / tilt device that can be used for both erection and tilting, occupies little space during transportation and operation, and is small, lightweight, and easy to transport. [Means for solving the problem]

[0011] A typical configuration of the lifting and tilting device according to the present invention is composed of a separate carriage and lifting device. The carriage has a short floor board, a long back board, and a locking block attached to the back board. The lifting device has a lifting block rotatably connected to the locking block, a lifting side support that guides the lifting block in the up and down direction, and a lifting side It is characterized by having a towing side support pillar connected to the support pillar and positioned on the tilting origin side, a first rope body that lifts the lifting block, a first reducer that pulls the first rope body, a second rope body connected to the floor board, and a second reducer that pulls the second rope body toward the towing side support pillar.

[0012] Preferably, the first reducer and the second reducer include an input shaft that receives a driving input from the portable power tool, and do not include a motor.

[0013] Preferably, the floor and back panels of the carriage are fitted with skids. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide an erection / tilt device that can perform both erection and tilting, occupies a small space during transportation and operation, and is small, lightweight, and easy to transport. [Brief explanation of the drawings]

[0016] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0017] 1 is a diagram illustrating the configuration of an erection / tilting device 100 according to this embodiment. The erection / tilting device 100 is composed of a carriage 200 and a lifting device 300, which are separate bodies.

[0018] The cart 200 is composed of a short floor plate 210 and a long back plate 220. The floor plate 210 and back plate 220 may have the same width, and are generally L-shaped. Plastic sliding members are attached to the surfaces of the floor plate 210 and back plate (the inner surfaces of the L shape).

[0019] Wheels 214 are attached to the underside of the floor board 210. Wheels 222 and 224 are attached to the underside of the back board 220. Wheels 222 are attached to the corners of the floor board 210 and back board 220 and are used both for the bottom board and the back board. The back board 220 has a locking block 230.

[0020] The lifting device 300 has a two-pillar gate-shaped traction-side support 310 and two lift-side support 320, for a total of four pillars. The space between the two lift-side support 320 forms the entrance for the carriage 200, and the traction-side support 310 forms the rear wall. The rear wall is the side of the floorboard 210 (the side from which the carriage 200 tilts) when tilting. The box-shaped sides formed by the gate-shaped traction-side support 310 and the two lift-side support 320 are connected by braces 330 and front and rear beams 332. The lift-side support 320 are connected to each other by flat (thin) left and right beams 334 that run along the floor surface.

[0021] The lifting-side columns 320 are hollow rectangular pieces, and slits 322 that open in the vertical direction are formed on the inner surfaces that face each other. A lifting block 324 is disposed inside the lifting-side columns 320, and the inner surface of the lifting-side columns 320 guides the lifting block 324 in the vertical direction.

[0022] A first reducer 340 is attached to the pulling-side support 310. The first reducer 340 pulls a chain 346, which is an example of a first rope, via a gear shaft 344. The chain 346 is diverted downward by a sprocket 328 disposed at the inner upper end of the lifting-side support 320, and lifts the lifting block 324. The first reducer 340 has an input shaft 342 to which driving force is input from a portable power tool such as an electric drill driver (hereinafter referred to as power tool 20).

[0023] A protective device such as an acrylic cover may be attached to the side of the lifting device 300. This will prevent the chain from coming into contact with the worker if it breaks, and will prevent the worker's hands or clothing from getting caught in the chain.

[0024] Furthermore, a winch 350 as an example of a second reduction gear is attached to one of the towing-side columns 310, and a wire 356 as an example of a second rope body is stretched between the winch 350 and a hook 354 provided on the other column. A movable pulley 358 is attached to the wire 356, and the wire 356 is connected to a U-shaped metal fitting 216 on the floor plate 210 of the cart. Therefore, the winch 350 can tow the wire 356 toward the towing-side column 310, or slacken and reel out the wire 356. Like the first reduction gear 340, the winch 350 also has an input shaft 352 to which driving power is input from the power tool 20.

[0025] The lifting device 300 can be stored and transported disassembled into individual components (pillars and beams), and then assembled and used at the work site. In a prototype in which each component was made of steel, the assembled weight was approximately 250 kg, the total height was 1600 mm, and the width was 1040 mm. Note that further weight reduction can be achieved by using aluminum alloy instead of steel for all or part of each component.

[0026] Next, the steps for erecting a distribution board will be described with reference to Figures 2 to 8. As shown in Figure 2, first, the cart 200 is laid on its side with the back panel 220 facing the ground. Then, the distribution board 10 is placed on the back panel 220 of the cart 200. This work can be done outdoors, so the distribution board 10 can be placed using a crane (not shown) or the like. Here, a sliding member is attached to the surface of the back panel 220, making it easy to shift the distribution board 10 and adjust its position.

[0027] 3, the cart 200 is moved by the wheels 222, 224, and is inserted between the two lift-side supports 320, with the floor board 210 at the head. It is preferable to fasten the cart 200 and the switchboard 10 with a belt 12 to prevent them from slipping.

[0028] 4, the carriage 200 is advanced until the hole 326 of the lifting block 324 is aligned with the hole 232 of the locking block 230, and then the pipe 360 ​​is inserted. This rotatably connects the locking block 230 and the lifting block 324. In this embodiment, the blocks 230 and 324 are connected using the pipe 360, but they may also be rotatably connected using a chain and hook, etc.

[0029] Next, as shown in FIG. 5 , the process of erecting the switchboard 10 begins. First, the movable pulley 358, which is pulled by the winch 350, is connected to the U-shaped bracket 216 on the floor plate 210 of the cart. Then, the power tool 20 inputs driving force from the input shaft 342 to the first reducer 340, which pulls the two chains 346 via the gear shaft 344. The chain 346 then changes its pulling direction from the lateral direction from the pulling-side support 310 to the lifting-side support 320 to an upward direction by the sprocket 328, lifting the lifting block 324. Since the lifting block 324 and the locking block 230 are connected, the back plate 220 of the cart 200 is lifted, and the upper part of the switchboard 10 is lifted at an angle. Note that the position of the locking block 230 needs to be closer to the upper part of the switchboard 10 than the center of gravity of the switchboard 10.

[0030] As shown in FIG. 6 , as the first reducer 340 winds up the chain 346, the switchboard 10 continues to rise. Since the wire 356 is connected to the U-shaped bracket 216 of the platform 210 of the cart, the platform 210 cannot approach the floor. The lifting block 324 is then raised until the center of gravity of the switchboard 10 and the cart 200 moves closer to the platform 210 than the wheels 222, and the first reducer 340 is stopped. At this point, the switchboard 10 is suspended at an angle by the pipe 360 ​​and the wire 356. Depending on the gear ratio of the first reducer 340 and the winch 350, the chain 346 and the wire 356 can support the weight of the switchboard 10 even when the power tools 20 are removed from the input shafts 342 and 352.

[0031] 7, the input shaft 352 of the winch 350 is rotated by the power tool 20 to pay out and loosen the wire 356. This causes the floorboard 210 to descend toward the floor, and the switchboard 10 is erected. In this way, the switchboard 10 can be erected gradually, so that no impact occurs when erecting, and it will not fall to the other side due to the force.

[0032] 8, once the switchboard 10 is erected, the movable pulley 358 is removed from the U-shaped metal fitting 216. Furthermore, the pipe 360 ​​is pulled out to release the connection between the lifting block 324 and the locking block 230. This frees the cart 200, allowing it to be removed from the lifting device 300.

[0033] 9 and 10 are diagrams illustrating the steps for installing the switchboard 10. The switchboard 10 is fixedly installed on rails 30 installed on the floor. Existing switchboards 10 are lined up on the rails 30, and a new switchboard 10 is installed on the vacant rail 30 next to them.

[0034] 9, the distribution board 10 is moved to the installation location by a cart 200, but the new distribution board 10 and the existing distribution board 10 have protrusions such as switches, making it difficult to move them too close. It is also difficult to move the cart 200 carrying the very heavy distribution board 10 along the rails 30 without any gaps.

[0035] Therefore, in this embodiment, a transfer table 400 is used to move the switchboard 10 from the carriage 200 to the rails 30. The transfer table 400 has a sliding member attached to the upper surface of a floor panel 410. In addition, height adjustment bolts 420 are attached to all four sides of the transfer table 400.

[0036] 10, with the floor plate 210 of the carriage, the transfer table 400, and the rails 30 lined up without any gaps, the switchboard 10 is pushed or pulled to move it onto the rails 30. This completes the installation of the switchboard 10.

[0037] When removing the switchboard 10, the above steps can be performed in reverse order to tilt the switchboard 10 onto its side. That is, after pulling the wire 356 to lift the floor board 210 of the cart 200, the chain 346 is let out to lower the pipe 360, thereby gradually tilting the switchboard 10.

[0038] As described above, the erection / tilting device of the present invention allows a small number of people to safely and efficiently erect and install a distribution board, or remove and lay it on its side to transport it. Furthermore, because the structure is simple, no special training is required, and the device has the advantages of being easy to install and use. Furthermore, because the bodies of the cart 200 and the lifting device 300 are constructed from pillars and braces, the overall weight can be reduced.

[0039] Furthermore, since the distribution board 10 is not suspended from above but stands up by lifting the pipe 360, the height of the entire device can be made low and compact, and it can be applied to any existing distribution board room height.

[0040] Furthermore, since the cart 200 and the lifting device 300 are separate and can be easily disassembled and assembled, they can be loaded into a minivan and brought to a work site, and two people can move them indoors and up stairs.

[0041] In the above embodiment, a distribution board is used as an example of an article that can be raised or tilted, but the present invention is not limited to distribution boards. It can also be used for various articles (e.g., tanks, containers, etc.) that can be carried into a building on their side and then raised up inside the room.

[0042] While 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 clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.
