Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended for a fuel cell power plant or the like, and when a plant equipment consisting of a collective assembly of a plurality of units is installed on site, it is attached to each unit to support the carrying-in and installation work. Support jig for doing.

[0002]

2. Description of the Related Art First, FIG. 6 shows the configuration of a fuel cell power plant described above as an example of plant equipment. In the figure, 1 is a fuel cell unit, 2 is a fuel reforming unit,
3 and 4 are auxiliary units of the fuel reforming unit 2, 5 is a DC / AC conversion inverter unit, and 6 is a control panel unit, and these units (consisting of columns and bottoms standing at the four corners and an underframe on the ceiling side) A structure in which devices are housed in a case in which a peripheral surface of a rigid frame is covered with panels is combined as shown to construct a fuel cell power plant. Moreover, the size and weight of each unit in such a configuration varies depending on the capacity of the power plant, and the output is 500 KW.
In a class plant, each unit is around 3 m high and weighs a few tons.

By the way, the above-mentioned fuel cell power plant is often installed and used in a building (basement) such as an office building for private power generation, but these buildings do not have crane equipment unlike a factory. In most cases. Therefore, in order to bring the power plant assembled in the factory to the site and install it, after mounting each unit on a trailer etc. and transporting it to the site, a roller cart for transportation,
Tools such as rollers, jacks, and fixed hoists assembled on-site are used to manually move to the installation position in the building, and a wooden auxiliary frame (slipper) is temporarily installed to prevent the unit from falling over. The current situation is that they are carried in and installed.

[0004]

However, the carrying-in method using a roller or the like is inefficient in work, and a large number of workers need time and labor to carry in and install plant equipment. As a result, there is a strong demand for improvement measures to safely and efficiently carry in the installation and installation of equipment.

The present invention has been made in view of the above points, and it is an object of the present invention to use a small number of support jigs in the right places when installing plant equipment consisting of a collective assembly of a plurality of units. The purpose of this is to provide a support jig for installation of plant equipment that enables efficient loading and unloading of units.

[0006]

In order to achieve the above object, the support jig of the present invention is constructed as follows. (1) One jig is equipped with at least two or more of wire lifting hook, side pulling hook, jack claw pedestal, moving roller mounting pedestal, and fall prevention arm. Therefore, concretely, it is recommended to divide the support jig into the following types according to use and function.

A) As a support jig for jack operation and wire lifting, a mounting plate for bolting to a bottom underframe of a unit, a jack claw pedestal, and a wire hanging hoisting that also serves as a support arm of the pedestal. Line up hooks. b) As a support jig for roller movement and fall prevention, a fall prevention arm is connected to a mounting plate that is bolted to the bottom frame of the unit, and a movement roller attachment base is provided at the bottom of the tip of the fall prevention arm. .

C) In the support jig of the above item b), a lifting hook for hanging a wire is provided on the upper surface of the fall prevention arm. d) As a support jig for roller movement and fall prevention, a horizontal pulling prevention arm that is bolted to the bottom base frame of the unit is provided with horizontal pulling hooks and mounting bases for the moving rollers at the bottoms at the left and right ends.

Further, as a support jig used when raising and lowering a unit case between adjacent units, there is the following structure. (2) It consists of a mounting bracket that is bolted to the upper edge of the unit, and a jack claw cradle that is connected to the side of the unit. The jack installed on the adjacent unit allows the unit to be raised and lowered. To do.

(3) Between adjacent units having different height dimensions, a mounting member with a bolt washer for fixing to the upper surface of a tall unit and a pair of the bolt washer to be fixed to the upper surface of a short unit. And a suspension bolt spanning between the bolt washers, and a screw operation of the suspension bolt allows a short unit to be pulled up and down.

[0011]

[Function] By adopting the above-mentioned various support jigs in the right places and mounting the jigs selected according to the work content to the plant equipment unit, the unit can be carried in and installed at the installation site as follows. Work can be carried out safely and efficiently. Here, by attaching the support jigs in the item (1) -a) to the four corners of the bottom underframe of the unit, the wire can be lifted and lowered, and the jack operation can be performed. Also,
By using the jig of item b) or d), the unit that is prone to fall can be supported in a stable posture to move the rollers on the floor surface of the installation site, and the jig of item c) can be used for the lifting hook. By attaching the unit, the wire of the unit can be lifted up, and with the jig in the item d), the wire can be pulled horizontally.

On the other hand, when another unit is installed next to the previously installed unit without a gap, depending on the arrangement condition of the units, the existing units adjacent to the unit interfere and the jack is used from the base side. Although it may not be possible, the support jig of (2) or (3) can be used under such conditions to lift or lower the unit by operating the jack or hanging bolt from the top of the unit. Is possible.

Embodiments of the present invention will be described below with reference to the drawings. Example 1 FIGS. 1 (a) and 1 (b) show a support jig (a type of jig is provided with a function corresponding to two applications of jack operation and wire lifting according to claim 2 of the present invention). The jig # 1 is welded to a mounting plate 7, a lifting hook 8 having a wire hooking hole 8a which is welded to the mounting plate 7 and protrudes at a right angle, and a tip lower surface thereof. It is composed of a jack claw support 9, and when used, the mounting plate 7 is a unit (reference numeral 1 shown in FIG. 6) as shown in FIG.
~ 6 units) bottom side underframe (channel steel) 1
Fasten with bolts 11 at the four corners of the 0 circumference.

By using this support jig, the claw 12a of the jack 12 installed on the foundation surface can be hooked on the claw receiving base 9 of the jig # 1 to raise and lower the unit by jacking as shown in the figure. Hole 8a for lifting hook 8
The wire of the unit can be lifted by hanging the wire 13 on. The movement of the unit is carried out by directly attaching the moving roller (direction changeable caster) to the bottom frame 10 of the unit with the unit being jacked up as described above, and rolling the moving roller on the floor surface. I shall.

Embodiment 2 FIGS. 2 (a) and 2 (b) are support jigs having functions corresponding to three uses of falling prevention, moving rollers and wire hoisting according to claims 3 and 4 of the present invention. (The type of jig is represented by # 2), and the jig # 2 is a mounting plate 7, a U-channel steel fall prevention arm 14 welded to the mounting plate 7, and a tip of the arm 14. Moving roller mounting base 15 and arm 14 provided on the bottom of the side
And a lifting hook 8 provided on the upper surface side of the. Incidentally, 14a is a reinforcing rib of the arm 14.

The jig # 2 having such a structure has a bottom side underframe 10 for a unit (a narrow unit 4 or 5 among the units shown in FIG. 6 which is easy to tip over) as shown in FIG.
The jig is fastened with bolts 11 so that the fall prevention arms 14 project forward and backward at the four corners of the circumference of the base 15.
A moving roller 16 with a handle is attached to the lower surface of the unit, and the unit is moved on the floor in this state. In addition, the wire 13 can be hung on the lifting hook 8 to lift the unit, if necessary in order to proceed with the work.

Embodiment 3 FIGS. 3 (a) and 3 (b) show support jigs (with different types of jigs) equipped with functions for preventing fall and corresponding to the application of the moving roller according to claim 5 of the present invention. # 3
