Description

An embodiment of the present invention relates to a method for transporting equipment in situations where lifting by crane is not possible.

When transporting heavy items such as electrical equipment or machinery, a crane is used to lift and move the item and set it up at the desired location. When installing plant equipment or substation facilities indoors, it may not be possible to use a crane.

Technology is known that uses screws to jack up the equipment to be installed or the equipment base that is installed at the installation location along with the equipment (see, for example, Patent Document 1). Designing jack-up screws for each piece of equipment and each equipment base results in limited versatility and lengthens the design time required to install the screws. Furthermore, when installing equipment mounted on an equipment base at its installation location, determining whether to install screws based on whether a crane can be used at the installation location complicates the design work for the equipment base, etc.

There is a need for a method to lift an equipment base loaded with equipment and transport it to the designated installation location, regardless of whether a crane is available at each installation location.

An embodiment of the present invention aims to provide an equipment transport method that uses a general-purpose jack to lift equipment and equipment bases and transport them to the desired installation location.

An embodiment of the present invention is an equipment transport method in which an installation including an equipment base provided with multiple lifting plates, each having multiple crane locking holes for locking to a crane when lifted by a crane, and equipment placed on the equipment base is placed on chill rollers and transported to a target installation location without using a crane. This equipment transport method involves preparing multiple jacking jigs, each having a pin that inserts into each of the multiple crane locking holes and an end plate joined to the pin so that it does not fall out of the multiple crane locking holes. The multiple jacking jigs are supported by multiple jacks positioned below the multiple jacking jigs that have inserted through the multiple crane locking holes, respectively. The installation is then lifted via the multiple jacking jigs, and transported to the installation location by chill rollers positioned between the lifted installation and the transport path along which the installation is transported.

According to this embodiment, an equipment transport method is realized in which a general-purpose jack is used to lift equipment and equipment bases and transport them to the desired installation location.

Hereinafter, embodiments will be described with reference to the drawings.
The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as those in reality. Furthermore, even when the same part is shown, the dimensions and ratios may be different depending on the drawing.
In the present specification and the drawings, elements similar to those described above with reference to the previous drawings are designated by the same reference numerals, and detailed descriptions thereof will be omitted as appropriate.
In the following description, viewing an object from above or below a plane that is substantially perpendicular to the direction of gravity may be referred to as planar view.

First, the configuration of members used to carry out the equipment transport method according to the embodiment will be described.
1A and 1B are schematic views illustrating a jack-up jig used in the equipment transport method according to the embodiment.
1(a) and 1(b), the jacking jig 10 is a pin 12 with an end plate 11. The pin 12 is inserted into a crane locking hole 26 in a lifting plate 25 of an equipment base 20, which will be described later in conjunction with FIG. 2. The pin 12 is a substantially cylindrical member, with a portion of the side surface of the cylinder chamfered, and the chamfered surface serves as a load surface 13. The load surface 13 is provided for abutting against the support part of the jack.

The pin 12 is long enough to be inserted through the crane locking hole 26 in the lifting plate, is narrower than the diameter of the crane locking hole 26 so that it can be inserted through the crane locking hole 26, and is thick enough to provide sufficient strength when jacked up. By making the pin 12 thinner than the diameter of the crane locking hole 26, the jacking jig 10 can be attached and detached to the crane locking hole 26. An end plate 11 is attached to one end of the pin 12. The end plate 11 is large enough so that it will not come loose from the crane locking hole 26. The end plate 11 and pin 12 are formed, for example, from steel and are joined to each other by welding.

2A and 2B are schematic views illustrating an equipment base used in the equipment transport method according to the embodiment.
2( a) and 2(b), the equipment base 20 has an upper plate 21, a lower plate 22, short H-shaped steel bars 23, long H-shaped steel bars 24, and a hanging plate 25. In the equipment base 20, two long H-shaped steel bars 24 are provided to sandwich both ends of the two oppositely arranged short H-shaped steel bars 23. In a plan view, the four H-shaped steel bars 23, 23, 24, 24 are combined in a rectangular shape and joined at their respective ends by, for example, welding. The upper plate 21 and the lower plate 22 sandwich the four H-shaped steel bars 23, 23, 24, 24 combined in a rectangular shape from above and below, and are joined to the four H-shaped steel bars 23, 23, 24, 24 by, for example, welding.

The lifting plate 25 is a plate-shaped member with a surface that is approximately perpendicular to the transport surface on which the equipment base 20 is placed and transported. When lifting the equipment base 20 with equipment mounted on it, the lifting plate 25 is subjected to a force in the direction of gravity against the loading surface of the equipment base 20. Therefore, the lifting plate 25 is joined to the H-beam 24, for example by welding, to ensure sufficient strength against the force in the direction of gravity.

A crane locking hole 26 is opened in the lifting plate 25. The crane locking hole 26 is provided through the lifting plate 25 in a direction approximately parallel to the conveying surface, which is a plane approximately perpendicular to the direction of gravity. By providing the crane locking hole 26 through the lifting plate 25 in a direction approximately parallel to the conveying surface, the pin 12 of the jack-up jig 10 can be inserted approximately parallel to the conveying surface. Therefore, when the pin 12 is supported by a jack, the lifting plate 25 is supported with sufficient strength, allowing the equipment base 20 to be raised.

The lifting plate 25 and crane locking holes 26 are also used when lifting the equipment base 20 with a crane and moving the equipment base. In this case, the crane locking holes 26 are provided through the lifting plate 25 in a direction approximately parallel to the transport surface. Therefore, when a crane rope, wire, hook, etc. is locked in the crane locking holes 26, it is difficult for them to come loose and they are locked with sufficient strength. Because the crane locking holes 26 are used to lock ropes, etc., their diameters are the same for multiple types of equipment bases. Therefore, the jack-up jig 10 inserted through the crane locking holes 26 can be used for multiple types of equipment bases.

The upper plate 21, lower plate 22 and four hanging plates 25 are made of, for example, steel and are sufficiently strong.

In this example, the equipment base 20 has two lifting plates 25 attached to each of the two H-beams 24. In other words, in this example, four lifting plates 25 are attached. The arrangement and number of lifting plates 25 are not limited to this and can be appropriately determined depending on the weight and floor area of the equipment and equipment base to be lifted, etc.

As will be described later in relation to Figure 3, the equipment 30 is placed on the equipment base 20. The equipment base 20 is transported with the equipment 30 placed on it, and is then installed at the desired installation location. In other words, the equipment base 20 is an installation object integrated with the equipment 30, and, for example, the equipment 30 is mounted on the equipment base 20 at the factory where it is manufactured and then shipped.

In the above example, the equipment base 20 is rectangular in plan view, but is not limited to this and can have any appropriate shape depending on the shape of the bottom of the equipment 30 to be mounted and the number of equipment to be mounted. The number of hanging plates 25 and the positions at which the hanging plates 25 are provided are set appropriately depending on the shape of the equipment base 20 in plan view, the weight of the equipment to be mounted, and the arrangement of the equipment.

3(a) and 3(b) are schematic diagrams illustrating installations in which equipment is mounted on the equipment bases of FIGS. 2(a) and 2(b).
3(a) and 3(b), the equipment 30 is mounted on the equipment base 20, and the equipment 30 is fixed to the equipment base 20 with, for example, bolts and nuts. The equipment 30 and the equipment base 20 on which the equipment 30 is mounted are collectively referred to as the installed object 40.

In addition to the components described above, chill rollers are also used to carry out the equipment transport method according to the embodiment. The chill rollers are provided between the object 40 to be installed and the transport path along which the object 40 is lifted and transported, and transport the object 40 to the desired installation position.

In addition to the components mentioned above, a jack is also used to carry out the equipment transport method according to the embodiment. The jack supports the jack-up jig 10 inserted into the crane locking hole 26 of the lifting plate 25, and jacks up the installed object 40. Specific examples of their use will be described in detail in the explanation of the equipment transport method according to the embodiment.

A device transport method according to an embodiment will be described.
4 to 6 are schematic diagrams for explaining the equipment transport method according to the embodiment.
First, the installation 40 consisting of the equipment base 20 and the equipment 30 is assembled, for example, in a factory that manufactures the equipment, and then transported to a construction site where the installation 40 is to be installed.

As shown in FIG. 4, the installation object 40 is moved from a parked vehicle to the transport path at the construction site. Auxiliary members G1 are placed on the transport path to provide space between the installation surface G2 on which the installation object 40 is to be placed and the installation object 40 so that a jack can be inserted. The installation object 40 is then lowered onto the auxiliary members G1. The auxiliary members G1 are, for example, steel members with a width shorter than the length of the short H-beam 23 of the equipment base 20. If the distance between the installation surface G2 and the jack-up jig 10 inserted into the lifting plate 25 is longer than the shortest length of the jack, the auxiliary members G1 may be omitted. When lowering the installation object 40 from the vehicle to the transport path, for example, the height of the vehicle's loading platform is adjusted to the height of the transport path, and then the installation object 40 is moved onto the auxiliary members G1.

As shown in Figure 5, the pins 12 of the jack-up jig 10 are inserted into the crane locking holes 26 of the four lifting plates 25. In this example, the pins 12 are inserted into the crane locking holes 26 of adjacent lifting plates 25 on the same H-beam 24 from opposite sides of the lifting plates 25, but this is not a limitation and they may of course be inserted from the same side.

A jack 50 is placed below each of the pins inserted into the four crane engagement holes 26. The four pins inserted into the crane engagement holes 26 are positioned so that the load surface 13 faces the jack 50 above it. Any type of jack 50 can be used. It can be a hydraulic jack, a mechanical jack, or the like.

As shown in Figure 6, the support parts of all jacks 50 are raised upward until they contact the load surfaces 13 of the pins 12, and then the support parts are further raised after contact. The jacking continues until the chill rollers 60 can be placed between the object 40 and the auxiliary member G1. After the chill rollers 60 are placed between the object 40 and the auxiliary member, the support parts of the jacks 50 are lowered and the jacks 50 are removed. The object 40 is transported to the desired installation location by the chill rollers 60.

Then, the object 40 transported to the installation site is lowered to the designated installation site using the jack 50, as described above. After the object 40 is installed, the jack 50 is removed, and the jack-up jig 10 is detached from the lifting plate 25. Note that the jack-up jig 10 may be removed from the crane engagement hole 26 after the object 40 is placed on the chill roller 60, and used for installing another object.

The effects of the equipment transport method according to the embodiment will be described.
In the equipment transport method according to the embodiment, the equipment base 20 of the installation object 40 has a lifting plate 25. The lifting plate 25 is lifted by a crane, and in order to ensure the joint strength with the H-beam 24 against a load in the direction of gravity, crane locking holes 26 are opened in the lifting plate 25 in a direction substantially parallel to the transport path of the equipment base 20. Therefore, the pin 12 of the jack-up jig 10 can be inserted through the crane locking holes 26 so as to be substantially parallel to the placement surface.

By inserting the pin 12 of the jack-up jig 10 into the crane engagement hole 26, the pin 12 can be supported on the support portion of the jack 50 in a direction approximately perpendicular to the direction in which the support portion of the jack 50 moves.

This allows the installation object 40 to be jacked up stably and the chill roller 60 to be positioned between the installation object 40 and the conveying path.

In this way, the installation object 40 can be lifted using the jack 50, jack-up jig, and lifting plate 25, so even at construction sites where a crane cannot be placed, installation objects, including heavy items, can be transported to the designated installation location.

Whether or not crane transport is possible, by providing a lifting plate 25 on the equipment base 20, there is no need to provide jacking means such as screws for each equipment base depending on the equipment installation site and equipment base.

A general-purpose jack 50 can be used. The jack-up jig 10 can be used to jack up the object before transport, then transported together with the object 40 and used to jack down the object 40 at the installation site. This eliminates the need to prepare dedicated screws, jacks, etc. for each object, improving productivity at construction sites, etc.

The pin 12 of the jack-up jig 10 has a flat load surface 13 that abuts against the support portion of the jack 50. This allows it to stably abut against the support portion of the jack 50, allowing heavy objects to be lifted safely.

The jack-up jig 10 has an end plate 11 attached to one end of the pin 12. The end plate 11 prevents the jack-up jig 10 from falling out of the crane locking hole 26 when the pin 12 is inserted into the crane locking hole 26. This makes it possible to implement the equipment transport method according to the embodiment with high productivity.

In this way, a method of transporting equipment can be realized that uses a general-purpose jack to lift equipment and equipment bases and transport them to the desired installation location.
