ABSTRACT:
TITLE OF THE INVENTION
Method for Installing and Removing Automatic Lift-Type Mobile Facility, Method of Automatic Lift-Type Power Generation, and Automatic Lift-Type Mobile Facility
BACKGROUND OF THE INVENTION
The present invention relates to a method for installing and removing an automatic lift-type mobile facility adapted to be used for the automatic lifting and lowering operation of a mobile facility which is designed to be mobile for installation at a desired location to accomplish a desired task, an automatic lift-type electric power generation method when said mobile facility is an electric power generation equipment unit, and an automatic lift-type mobile facility which is directly applied for the embodiment of the foregoing.
Mobile power generation equipment has been used in such applications as a power supply on construction sites, a temporary power supply for the duration before normal power supply is available, or an emergency power supply under circumstances where the normal power supply is suspended unexpectedly or expectedly according to a predetermined schedule.
For example, mobile power generation equipment has been used as a means of private power generation for such facilities as fire prevention facilities, public communication systems, flight control systems, medical institutes, nuclear reactors where power failure even for a minimum length of time is permitted for their social responsibilities. In these applications, normal power supply is switched to emergency power supply when a power failure occurs and then switched back when the normal power supply is resumed.
However, in order to maintain the normal performance of the emergency power supply mentioned above, periodical inspection of the emergency power supply and servicing for adjustment and repair of affected parts and functions are necessary, which inevitably interrupts the availability of the emergency power supply since such servicing work, requiring an overhaul of the emergency power supply equipment, may require a minimum of one day and a maximum of 10 days. During such suspended use of the emergency power supply equipment due to servicing, mobile power generation equipment is used as the substitute for said emergency power supply equipment.
For installing said mobile power generation equipment at a desired location demanding a power supply, mobile power generation equipment is loaded onto a carrying vehicle such as a standard motor-truck, large lorry, or trailer in accordance with the weight and size of said equipment. When loading the mobile power generation equipment onto such a carrying vehicle at the storage or shipping plant, slinging work with necessary slinging materials must be performed by slinging operators and then a mobile crane which is a load handling system must be operated by a crane operator.
After loading the equipment onto a carrying vehicle, the vehicle is driven by a driver to transport the mobile power generation equipment, to a desired location of use. Then the mobile power generation equipment is installed at said location by stinging the equipment with slinging materials and with slinging operators in attendance and unloading said equipment by the use of a crane operated by an operator.
In the same manner, when removing the mobile power generation equipment from said desired location of use, slinging work with necessary slinging materials must be performed by slinging operators and then a mobile crane must be operated by a crane operator to load said equipment onto a carrying vehicle such as a standard motor-truck, large lorry, or trailer. After that said equipment is transported to said storage plant on the carrying vehicle.
In addition to the examples described above, a mobile power-supply vehicle D provided with power generation equipment and a vehicle as an integrated unit, which falls under a special vehicle category, as shown in
FIG. 9
has been used.
FIG. 9
is an internal view of a conventional mobile power-supply vehicle, with (a) and (b) being top view and side view respectively.
The mobile power-supply vehicle D comprises a driver's cab d

provided on a truck body d which transports said power generation equipment, and a power generation section

D which is loaded integrally on the load-carrying platform d

and generates electric power. The power generation section

D includes a cubicle

D which is a housing, prime mover equipment
4
D which supplies prime mover for electric power supply, and electric power equipment
5
D which generates electricity by using the prime mover supplied by the prime mover equipment
4
D and supplies electricity as demanded.
The mobile power-supply vehicle D does not require procedures such as the loading or unloading of any item at a desired location of use of the system. Installation of the power generation section

D is completed by parking the mobile power-supply vehicle D itself in place.
The description above is related to mobile power generation equipment, however, other mobile facilities such as test equipment including a liquid rheostat, containers or other casing mechanism, mobile zoo or amusement, mobile swimming pool or hot spring, mobile shops, and other types of mobile structures, mobile displays at trade shows or the like have been loaded, transported, unloaded, installed, and removed in the same way, supported by slinging work with necessary slinging materials, with slinging operators in attendance and a mobile crane or other type of load handling system operated by a crane operator as well.
There are some cases where said mobile facility and carrying vehicle are integrated, for example, truck campers.
In the use of a conventional mobile power generation equipment unit, however, a load handling system as, well as slinging materials are necessary, which has created a problem in that the size of the system becomes extremely large. In addition, further problems in connection with the necessity of having a crane operator and slinging operators in addition to the driver of the carrying vehicle. In particular, it is becoming increasingly difficult to secure a crane operator since the operator has to possess an operating license.
When a crane is used, the operation runs the risk of endangering operators as well as equipment and facilities on the operation site due to the risk of a crane toppling or a load falling off the crane. Furthermore, if the carrying vehicle should break down on its way to the desired location of use and a new vehicle should be dispatched to the point of breakdown, a crane must also be dispatched for extra unloading and loading procedures.
With the size of mobile power generation equipment unit having been increased, the carrying vehicle must also be larger. As a result, the roads and the route to be taken by the vehicle for transportation are limited, or in the worst case the transportation plan itself becomes difficult to accomplish. In the same way, with the size of mobile power generation equipment unit having been increased, the operation area must become proportionally larger and the ground must be cured sufficiently to be firm enough to support the whole system.
Furthermore, when a large mobile power generation equipment unit is specified for installation, problems arise in that it is very hard to secure said mobile power generation equipment unit itself since the number of large systems is limited and the transportation distance becomes extremely long in connection with the difficulty in securing such system. In addition to these problems, when a crane is used, the operation runs the risk of endangering operators as well as equipment and facilities on the operation site. So it is impossible to install such mobile facilities at a place where no crane operation is permitted.
The problems mentioned above are related to mobile power generation equipment, however, the same type of problems apply to other mobile facilities. For example, mobile facilities with outriggers provided at four corners of a container are divided into two types. One is with outriggers attached to the co
