Description

  The present invention relates to a structure technology for a base for a stationary device, and more particularly, to a structure technology for a base for a stationary device that can jack up the stationary device.

Conventionally, stationary devices such as engine-driven heat pumps or engine generators are well known. At the bottom of these stationary devices, a stationary device base is provided. The base for stationary equipment is a lower structure that supports the stationary equipment on the foundation platform (ground).
For example, Patent Document 1 discloses an equipment floor intended for weight reduction and cost reduction as a base for stationary equipment.
Japanese Utility Model Publication No. 63-51995

  Stationary equipment needs to be installed horizontally on site. When the stationary device is installed at an angle, the package, which is the upper structure, is distorted, causing problems such as the open / close door provided in the device being opened freely or difficult to open / close. For this reason, the stationary equipment needs to be installed via a shim between the stationary equipment base and the foundation platform when the foundation platform on which the equipment is installed is inclined locally. A shim is a thin plate that is inserted between the stationary equipment base and the base platform in order to finely adjust the height of the stationary equipment. In other words, the stationary device may need to check the horizontal level of the device and set the horizontal level to insert a shim at the time of installation. In addition, in order to insert a shim, it is necessary to lift (float) the stationary device slightly from the base platform in order to insert a shim.

Conventionally, in the above-described horizontal leveling, the stationary device is lifted by a crane using a suspension fitting provided on the stationary device base, or is fixed using a nut and a jack bolt welded to the stationary device base. The work to lift the equipment was done. However, these operations are inferior in workability, and work man-hours are also spent.
Therefore, the problem to be solved is to improve the workability of the work of lifting the stationary device in the horizontal leveling at the time of installation of the stationary device.

  The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

  That is, according to the first aspect of the present invention, the stationary device base is provided at the lowermost portion of the stationary device and supports the stationary device on the ground, and includes at least one jack contact portion on the outer periphery.

  According to a second aspect of the present invention, in the stationary device base according to the first aspect, the stationary device base includes at least one hanging bracket member, and the jack abutting portion is provided on a lower surface of the hanging bracket member. .

  According to a third aspect of the present invention, in the base for a stationary apparatus according to the second aspect, the hanging bracket member is removable.

  As effects of the present invention, the following effects can be obtained.

  According to the first aspect of the present invention, it is possible to improve the workability of lifting the stationary device in the shim insertion work for leveling out when the stationary device is installed.

  According to the second aspect, in addition to the effect of the first aspect, the conventional hanging bracket has a jacking function, so that the component cost of the device can be reduced.

  According to the third aspect, in addition to the effects of the first and second aspects, since the hanging metal fitting that becomes a projection around the apparatus can be removed after the apparatus is installed, the safety of the apparatus can be improved. In addition, the hanging hardware can be reused.

Next, embodiments of the invention will be described.
FIG. 1 is a perspective view showing an overall configuration of a stationary generator according to an embodiment of the present invention, FIG. 2 is a perspective view showing a base, and FIG. 3 is a perspective view showing a hanging metal member. FIG. 4 is a perspective view showing an operation for jacking up the suspension member.

First, an engine-driven generator 1 will be briefly described as a stationary device that is an embodiment of the present invention with reference to FIG.
As shown in FIG. 1, the engine-driven generator 1 is a power generator that includes a fuel tank 14, a radiator 13, an engine 10, and a generator 11. The engine-driven generator 1 is configured by housing the devices 10, 11, 13, and 14 in a casing including a package 2 and a base 3 as a stationary device base.
The package 2 includes a side plate 4, an opening / closing door 5, and a top plate 6. The open / close door 5 is provided mainly for operating a control device (not shown) of the engine-driven generator 1 or for maintaining and inspecting the engine 10 and the generator 11.
The package 2 is provided with an exhaust tail pipe 8 and an air supply / exhaust hood 7. The exhaust tail pipe 8 is an outside outlet side of an exhaust pipe (not shown) for guiding the exhaust of the engine 10 to the outside of the engine driven generator 1. The supply / exhaust hood 7 is a hood for preventing rainwater from entering a ventilation / supply / exhaust port (not shown) that circulates in the package 2 and cools the radiator 13, the engine 10, and the generator 11.
Details of the base 3 will be described later.

Next, the base 3 as a stationary apparatus base will be described in detail with reference to FIG.
As shown in FIG. 2, the base 3 includes a base frame 25 that forms the outer peripheral four sides, and a plurality of beams 26 that are interposed in the short direction of the base frame 25 (the parallel direction of the short members 25 a). In the present embodiment, the base frame 25 is formed of a C-shaped rope, and the beam 26 is formed of a square pipe.
The base 3 includes a fuel tank mounting table 24, a radiator mounting table 23, an engine mounting table 20, and a generator mounting table 21 for mounting the fuel tank 14, the radiator 13, the engine 10, and the generator 11. ing.
Further, the base 3 includes at least one hanging member 30 around the base frame 25. A plurality of suspension metal members 30 are provided on the longitudinal member 25b constituting the base frame 25 (two in this embodiment).

Here, the hanging bracket member 30 will be described in detail with reference to FIG.
As shown in FIG. 3, the hanging metal member 30 is configured by a substantially rectangular plate made of metal. The hanging metal member 30 is formed with a hook hole 31 and a jacking notch 32.
The hook hole 31 is formed at substantially the center of the hanging metal member 30 and is sized so that a general-purpose hook can be sufficiently inserted.
The jack notch 32 is cut out at the lower surface of the portion protruding from the outer periphery of the base 3 in the state of being attached to the base 3. The jack abutting portion 33 is formed in the horizontal direction at the jack abutting notch 32. Furthermore, the space formed by the jacking notch 32 and the ground is large enough to insert the raising / lowering claw 41 (FIG. 4) of the jack 40. The hook hole 31 and the jacking notch 32 are attached so as to protrude outward from the outer end of the base frame 25b. Therefore, the hook or jack 40 does not interfere with the base 3 during the lifting operation.

Further, the suspension fitting member 30 is fixed to the suspension fitting member support member 36 at two locations by bolts 34 and nuts 35. That is, the hanging bracket member 30 is configured to be detachable from the hanging bracket member support member 36.
The suspension member 30 is formed with a thickness of 10 mm or more in this embodiment and has sufficient strength.

Next, the jack-up operation of the engine-driven generator 1 will be described in detail with reference to FIG.
The engine-driven generator 1 needs to lift (float) the suspension bracket member 30 slightly from the base platform (ground) in order to insert a shim that corrects the tilt when leveling at the time of field installation. It is. In this embodiment, the lifting operation is performed by jacking up using a jack. A jack is a device that is placed under an object to support or lift the object. Lifting with a jack is called jack-up.
As shown in FIG. 4, the jack 40 jacks up the engine-driven generator 1 by raising and lowering (jacking) the lifting claws 41 in contact with the jack abutting portion 33 of the hanging metal member 30. The jacks 40 range from small to large, and from mechanical to liquid actuated, and the type of the jack 40 of this embodiment is not particularly limited.
On the other hand, in loading and unloading the engine-driven generator 1 onto a truck bed or the like, a crane hook is hooked on the hook hole 31 of the hanging bracket member 30 so that the engine-driven generator 1 can be operated with a crane as in the past. Can be lifted.

With such a configuration, it is possible to improve the workability of lifting (jacking) the engine-driven generator 1 in the horizontal leveling when the engine-driven generator 1 is installed.
In addition, since the jack abutting portion 33 is formed on the hanging metal member 30, the hanging metal member 30 has both functions of the hanging metal member 30 and the jack abutting portion 33, and the parts cost can be reduced.
Furthermore, since the hanging bracket member 30 which becomes a protrusion around the device after installation can be removed, it is possible to prevent an operator from catching his / her foot on the hanging bracket member 30. That is, the safety of the engine-driven generator 1 can be improved.
Further, the hanging bracket member 30 can be reused every time the engine-driven generator 1 is installed.
