Description

[Technical Field]

[0001] An embodiment of the present invention relates to a method for transporting equipment in a situation where lifting by a crane is not possible. [Background technology]

[0002] When transporting heavy objects such as electrical equipment or machinery, a crane is used to lift and move the object and set it at the desired location. However, when installing plant equipment or substation facilities indoors, it may not be possible to use a crane.

[0003] There is known a technique for jacking up equipment using screws for each equipment to be installed or for each equipment base that is installed at the installation location together with the equipment (for example, Patent Document 1). Designing screws for jacking up for each equipment and equipment base results in poor versatility and lengthens the design time required to install the screws. Furthermore, when installing equipment installed on an equipment base at an 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.

[0004] There is a need for a method for lifting an equipment base with equipment mounted thereon and transporting it to a designated installation location, regardless of whether a crane is available at each installation location of the equipment base. [Prior art documents] [Patent documents]

[0010] 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.

[0011] First, the configuration of members used to carry out the equipment transport method according to the embodiment will be described. 1(a) and 1(b) are schematic views illustrating a jack-up jig used in the equipment transport method according to the embodiment. As shown in Figures 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 Figure 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 the support part of the jack to abut against.

[0012] The pin 12 has a thickness that is sufficient to be inserted through the crane locking hole 26 of the lifting plate, is thinner 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 to and detached from the crane locking hole 26. An end plate 11 is provided at one end of the pin 12. The end plate 11 is large enough so that it will not come out of the crane locking hole 26. The end plate 11 and the pin 12 are formed, for example, from steel and are joined to each other by welding.

[0013] 2(a) and 2(b) are schematic views illustrating an equipment base used in the equipment transport method according to the embodiment. As shown in Figures 2(a) and 2(b), the equipment base 20 has an upper plate 21, a lower plate 22, short H-shaped steel 23, long H-shaped steel 24, and a hanging plate 25. In the equipment base 20, two long H-shaped steels 24 are provided to sandwich both ends of the two oppositely arranged short H-shaped steels 23. In a plan view, the four H-shaped steels 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 steels 23, 23, 24, 24 combined in a rectangular shape from above and below, and are joined to the four H-shaped steels 23, 23, 24, 24 by, for example, welding.

[0014] The lifting plate 25 is a plate-like member having a surface that is approximately perpendicular to the conveying surface on which the equipment base 20 is placed and conveyed. When the equipment base 20 with equipment mounted thereon is raised, the lifting plate 25 receives a force in the gravitational direction against the placing surface of the equipment base 20, and therefore is joined to the H-beam 24 by, for example, welding so as to have sufficient strength against the force in the gravitational direction.

[0015] The lifting plate 25 has a crane locking hole 26. The crane locking hole 26 is provided so as to penetrate the lifting plate 25 in a direction substantially parallel to the conveying surface, which is a plane substantially perpendicular to the direction of gravity. By providing the crane locking hole 26 so as to penetrate the lifting plate 25 in a direction substantially parallel to the conveying surface, the pin 12 of the jack-up jig 10 can be inserted substantially parallel to the conveying surface. Therefore, when the pin 12 is supported by a jack, the lifting plate 25 is supported with sufficient strength, and the equipment base 20 can be lifted.

[0016] The lifting plate 25 and the crane locking holes 26 are also used when the equipment base 20 is lifted by a crane and moved. In this case, the crane locking holes 26 are provided through the lifting plate 25 in a direction substantially parallel to the transport surface. Therefore, when a crane rope, wire, hook, or the like is locked in the crane locking holes 26, it is difficult for the rope, wire, hook, or the like to come loose and is locked with sufficient strength. Because the crane locking holes 26 are used to lock ropes, the diameter of the crane locking holes 26 is the same for multiple types of equipment bases. Therefore, the jack-up jig 10 inserted through the crane locking holes 26 can be commonly used for multiple types of equipment bases.

[0017] The upper plate 21, the lower plate 22 and the four hanging plates 25 are made of, for example, steel and have sufficient strength.

[0018] In this example, the equipment base 20 has two lifting plates 25 provided at two locations on each of the two H-beams 24. That is, in this example, the lifting plates 25 are provided at four locations. The arrangement and number of the lifting plates 25 are not limited to this and are appropriately set depending on the weight, floor area, etc. of the equipment and equipment base to be lifted.

[0019] As will be described later with reference to Fig. 3, the equipment 30 is placed on the equipment base 20. The equipment base 20 is transported with the equipment 30 placed thereon and is then installed at a desired installation location. In other words, the equipment base 20 is an installation object integrated with the equipment 30, and the equipment 30 is mounted on the equipment base 20 at the factory where the equipment 30 is manufactured and then shipped.

[0020] In the above example, the equipment base 20 is rectangular in plan view, but is not limited to this and may 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 appropriately set 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.

[0021] 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 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.

[0022] In addition to the components described above, chill rollers are used to carry out the equipment transport method according to the embodiment. The chill rollers are provided between the object 40 and the transport path along which the object 40 is lifted and transported, and transport the object 40 to the desired installation position.

[0023] In addition to the components described above, a jack is 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 installation object 40. Specific examples of their use will be described in detail in the explanation of the equipment transport method according to the embodiment.

[0024] A device transport method according to an embodiment will be described. 4 to 6 are schematic diagrams for explaining the device 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.

[0025] As shown in FIG. 4 , the installation object 40 is moved from a parked vehicle to a transport path at the construction site. An auxiliary member G1 is arranged on the transport path to provide a 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 member G1. The auxiliary member G1 is, for example, a steel member 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 member G1 may be omitted. When the installation object 40 is lowered 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 member G1.

[0026] 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 provided on the same H-beam 24 from opposite sides of the lifting plates 25, but this is not limitative and they may of course be inserted from the same side.

[0027] Jacks 50 are respectively placed below the pins inserted into the four crane locking holes 26. The four pins inserted into the crane locking holes 26 are placed so that the load surface 13 faces the jack 50 above the jack 50. There is no restriction on the type of jack 50 that can be used. It may be a hydraulic jack, a mechanical jack, or the like.

[0028] As shown in Figure 6, the support parts of all jacks 50 are raised upward until they abut against the load surfaces 13 of the pins 12, and the support parts are further raised after abutment. The jacking is continued until the chill rollers 60 can be placed between the object 40 to be installed and the auxiliary member G1. After the chill rollers 60 have been placed between the object 40 to be installed and the auxiliary member G1, the support parts of the jacks 50 are lowered and the jacks 50 are removed. The object 40 to be installed is transported to the desired installation location by the chill rollers 60.

[0029] Thereafter, the object 40 transported to the installation site is lowered to the predetermined installation site using the jack 50, in the same manner 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 engaging hole 26 after the object 40 is placed on the chill roller 60, and may be used for installing another object.

[0030] 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.

[0031] By inserting the pin 12 of the jack-up jig 10 into the crane locking hole 26, the pin 12 can be supported by the support portion of the jack 50 in a direction substantially perpendicular to the direction in which the support portion of the jack 50 moves.

[0032] Therefore, the installation object 40 can be jacked up stably and the chill roller 60 can be arranged between the installation object 40 and the conveying path.

[0033] In this way, the installation object 40 can be lifted using the jack 50, the jack-up jig, and the lifting plate 25, so that even at a construction site where a crane cannot be placed, installation objects including heavy objects can be transported to the designated installation location.

[0034] Whether or not crane transportation is possible, as long as a lifting plate 25 is provided 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.

[0035] A general-purpose jack 50 can be used. The jack-up jig 10 can be used to jack up an object before transport, and then transported together with the object 40 to be jacked down at the installation site. This eliminates the need to prepare dedicated screws, jacks, etc. for each object, improving productivity at construction sites, etc.

[0036] The pin 12 of the jacking jig 10 is provided with a load surface 13, which is a flat surface that abuts against the support portion of the jack 50. This allows the pin 12 to stably abut against the support portion of the jack 50, allowing heavy objects to be lifted safely.

[0037] The jacking jig 10 has an end plate 11 attached to one end of the pin 12. The end plate 11 prevents the jacking 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.

[0038] In this way, it is possible to realize a method for transporting equipment by using a general-purpose jack to lift the equipment or equipment base and transport it to a desired installation location.

[0039] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
