Description

A TRANSPORTABLE WORK SHOP SYSTEM The present invention relates to a transportable work shop system comprising a flat rack bed and loading elements connected to or forming part of said flat rack bed for loading and unloading said flat rack bed on and off a mobile carrier, and a plurality of fixation elements provided on or in said flat rack bed and being configured for releasably fixation of a plurality of work shop units to an upper surface of said flat rack bed. BACKGROUOND OF THE INVENTIONRepair and maintenance of a larger mechanical construction are today often carried out either by transporting mechanical construction to a special repair and maintenance shop or transporting mechanical tools needed to the cite of larger mechanical construction. When a larger mechanical construction has, for instance, workable wheels but cannot otherwise move by its own motion, it may be possible to tow the mechanical construction to a repair shop. However, if the wheels are non-workable or the mechanical construction cannot move on its own motion for other reasons, simply due to being a fix construction, repair is often a prolonged process as the root of failure often not is know prior to having dismantled a number of parts and elements during fault finding process.  During a fault finding process, the mechanic may or may not have the correct tools in his tool box to find the fault. Further, mechanics trained to carry out different specialised repair or maintenance operations are often needed and each of the mechanics has their own tools for their specialized area.  Thus, in case of a break-down of a larger mechanic construction where towing to a workshop is not possible or feasible, the mechanics will have to go to the larger mechanical structure. At the site, the mechanics will – due to their a priori lack of knowledge about what is a cause of a mall function – quite often find themselves in a situation where they are lacking one or more tools for completing the operation. When this happens, the mechanics will have to acquire the missing tool, which obviously prolongs the repair time.  OBJECTS OF THE INVENTIONIt is an object of the present invention to provide repairment and / or maintenance in a more versatile manner. It is an object of the present invention to provide a more effective repairment and / or maintenance. It is a further object of the invention to provide an alternative to the prior art.

The body may be a floor on which different tools either are or can be attached to. In preferred embodiments, the body and tools are connected to each other so that the unit form a unitary element in the sense the body and the tools can be moved as a single element.  Many tools requires electrical power, and to provide such electrical power, the work shop system has an electrical power supply 20. The electrical power supply is typically equipped with power take outs (sockets) for different types of plugs, e.g. to allow for easy connection of different tools. Repair of a device, such as a vehicle, quite often involves lifting of parts being heavier than what a human can lift. To provide a possibility to perform lifting of heavy parts, the work shop system comprising a crane 16. In the embodiments shown in Fig. 2A and 2B, the crane 16 is a crane being rotatable around a vertical axis (perpendicular the plane of the flat rack bed 2), and being extendable / retractable by hydraulic operated telescopic members in vertical direction and in the direction of the boom. The hydraulic is typically electrically driven by an electrically powered hydraulic pump, and is powered by the electrical power supply 20. The hydraulic pump is typically comprised in the transportable work shop. In preferred embodiments, the power supply 20 is an electrical generator driven by a combustion engine. Such a combustion engine is also part of the work shop system and the electrical generator and combustion engine may form a work shop unit. The electrical generator is typically configured to provide an alternating electrical power at a voltage between 110 and 400 volts, such as between 220-250 volts. The current provide by the power supply 20 typically between 10 and 150 amps and the electrical generator is typically configured to provide the power at a frequency of 50 Hz or 60 Hz. By an electrical generator configured in this manner, the most commonly used electrical power needs may be covered. In preferred embodiments, the loading elements 3 comprising a number of parts of the work shop system.

As shown in Fig. 1B, the engagement element 3a comprising a through-going opening (illustrated by an elliptic figure). Upon loading and unloading of the work shop system, a crane located on the mobile carrier hooks into the through-going opening and lifts the first end 11 while either pushing the work shop system backward (in the direction of the second end 12 of the flat rack bed) during unloading, or dragging the work shop system forward (opposite direction) during loading.  In the embodiment illustrated in Fig. 1A, the engagement element 3a including the upright post 24 is positioned outside the perimeter of the flat rack bed 2. In preferred embodiments, the engagement element 3a, including if present an upright post 24, is positioned inside the perimeter of the flat rack bed. At the underside of the flat rack bed 2, two parallel runners 3b are positioned. The runners 3b extend from the first end 11 towards the second end 12 of the flat rack bed 2. During loading and unloading these runners 3b cooperates with corresponding rollers provided typically at a rear end of the mobile carrier so that when the work shop system is loaded or unloaded, the runners 3b contact the rollers, which rotate when the work shop system is moved. When the work shop system is located on the ground, an underside of the runners 3b contact the ground. As the work shop system typically is loaded and unloaded in with gradually increased or decreased inclination, the second end 12 will most often be the first and last point of contact between the flat rack bed 2 and the ground. To ease movement of the work shop system a pair of rollers 3c are arranged at the underside of flat rack bed 2 at the second end 12 which rollers 3c greatly reduced the friction between the ground and the work shop system.  In preferred embodiment, a plurality, such as all, of fixation elements 4 each comprises a threaded bore provided in the flat rack bed 2. These threaded bores are configured for bolting a work shop unit onto the flat rack bed. In the embodiment illustrated in Fig. 2B, the threated bores are arranged in lines extending across the width of the flat rack bed 2. However, other arrangements of the threaded bores may be used. The threaded bores typically extend from the upper surface and into the flat rack bed 2 so as to allow for receipt of a threaded bolt in the threaded bore from the upper surface for fixation of one or more of work shop units 5 to the upper surface of the flat rack bed. By using threaded bolt and bores, the work shop units may be removed or placed in a different position simply by releasing the bolts.  In addition or as alternative to threaded bores, a plurality, such as all, of said fixation elements 4 each comprises a through going non-threaded bore extending from said upper surface to a lower position of said flat rack bed. By this, a work shop unit can be fixated to the flat rack bed 2 by bolt going through the flat rack bed 2. Thus, such through going bores are configured to cooperate with a bolt and a nut placed at the underside of the flat rack bed 2 for fixation of one or more of work shop units 5 to the upper surface. Cooperate with a bolt and nut typically refers to that a bolt may go through the bore and that the bore is provided in a material allowing for fastening the nut and bolt without severely deforming the flat rack bed 2. In addition or as alternatively to threaded bores and / or through going non-threaded bores, one or more such as all of the fixation elements 4 comprising a tie-down bracket. Such tie-down brackets are in particular useful for fixation of work shop units or other elements by one or more straps.  In preferred embodiments, the work shop system is dimensioned so that the flat rack bed 2 has a width between 2.0 and 4.0 meters, such as between 2.5 and 3.0 meters and a length between 12.0 and 5.0 meters, such as between 10.0 and 6 meters. Here length refers to the longer of the horizontal directions of the flat rack bed. It if furthermore preferred that the flat rack bed 2 has a rectangular shape as view from an above position (a view as in Fig. 2B).

The compressor is typically electrically driven and is connected to the electrical generator disclosed above.  In preferred embodiments, one of the work shop units 5 comprises a locker 21 for storing containers, such as jerrycans, configured for holding fuel.  Preferably, at least some of the work shop units 5 are configured for fixation to flat rack bed 2 by being bolted onto said bed by one or more bolts. Such a fixation may be provided by the work shop units 5 have fittings connected to or forming part of a floor member of the work shop units 5 through which fittings bolts can extend.  It may be useful to survey, such as monitor the functioning or operation of the work shop system. To accomplish this, the transportable work shop may comprise an electronic surveillance unit configured to receive data from:tools of one or more of the work shop units and / orthe electrical power supply 20 and / orthe crane 16.  The data received may typically represent fault codes or state(s) of operation codes. The fault codes may be displayed on a display readable by a human. The fault codes may be numbers, letters or a combination thereof. Alternatively or in combination an explanation of the fault code and, preferably, precautionary actions to take (if necessary) may be displayed. A state of operation may e.g. be a temperature, pressure and / or electrical power consumption.  It may also be useful to provide a wireless communication between the electronic surveillance unit and a central surveillance unit being located remote from the work shop unit. To accomplish this, the electronic surveillance unit is configured to wireless communication with an central surveillance entity, such as to transmit to the central surveillance unit fault codes and / or state(s) of operations codes. In preferred embodiment, the wireless transmission is via GSM. The wireless transmission may be a secure transmission, e.g. by use of VPN. The communication between the electronic surveillance unit and the central surveillance entity may be bi-directional, so that the central surveillance entity may respond to e.g. an error code by transmitting to the electronic surveillance unit correctional measures to be carried out. The central surveillance unit is an electronic unit, and is preferably configured for transmission with a plurality of transportable work shop systems.  It is often preferred to configured the transportable work shop for being operable down to an ambient temperature of minus 32oC, preferably down to an ambient temperature of minus 40oC. This is preferably accomplished by selecting materials for the construction of the transportable work shop being capable of handling load and stresses during operation at the ambient temperature without breaking by designed use. In addition, the electronics and electrical components are also selected to be operable at the low ambient temperature.  It may also be advantageous to harvest electrical energy e.g. during transport of the work shop and store the harvested electrical energy for use by tools or equipment of work shop. To this, the work shop may comprise an electrical storage and solar panel(s) arranged to charge the electrical storage. In combination with or alternatively to solar panels, the power supply of the work shop may be connected to said electrical storage. The electrical storage may be a battery such as a Lithium-ion battery.  During use of the transportable work shop, the work shop is typically resting on a surface. During such use, one or more relatively heavy components, such as engines, may be broad onboard work shop which may cause a tilt of the work shop. A risk of such tilting may be increased during use of the crane 16 as a hoisting of a component involves a pick-up position outside a perimeter of the flat rack bed 2 and hoisting the component to a position inside the transportable work shop. A pick-up position outside the perimeter of the flat rack bed 2 may shift the center of gravity of the transportable work shop to an extend resulting an undesired tilting of the transportable work shop. To at least mitigate tilting of the transportable work shop, the transportable work shop may comprising at least one supporting device 17. In preferred embodiments, the transportable work shop has two supporting devices 17. Such a supporting device is configured to support said transportable work shop. Typically, such a support is provided by the supporting device is connected with the transportable work shop is has an element which can be engaged to extend towards and abut a surface on which the transportable work shop is resting. The point at which the element abuts may advantageously be a position outside the perimeter of the flat rack bed 2. The supporting device(s) 17 is typically engaged during operation of the crane 16, e.g. to counter act a shift in center of gravity during use of the crane 16.  The surface on which the transportable work shop is resting during use is not necessarily a flat and level surface, it may be inclined and have holes and peaks. As it is generally preferred that the flat rack bed 2 is horizontally oriented, the supporting device(s) 17 may be configured to at least partly level said transportable work shop, so that the flat rack bed 2 becomes more horizontally orientated, such as horizontally orientated, compared to a situation without the levelling function of the support device(s) 17. The levelling is typically provided by the supporting devices raises e.g. a corner or a side of the flat rack bed 2.  In embodiments where the supporting device(s) 17 abuts a surface on which the transportable work shop is resting in one or more positions outside the perimeter of the flat rack bed 2, the supporting device(s) 17 is configured to be arranged in a parking position where of the supporting device 17 does not extend horizontally outside the flat rack bed 2. If the transportable work shop is provided with more than one supporting device 17, it is generally preferred that all supporting device do not extend beyond the perimeter of the transportable work shop. That the supporting device(s) 17 does not extend the perimeter has the advantage that foot print of the transportable work shop is not increased by the supporting device(s) 17 when positioned in the parking position.  Reference is made to Fig. 3A-3D illustrating a preferred embodiment of a transportable work shop, where the transportable work shop comprises two supporting devices 17.
