Description

System for load handling
The invention relates to a system for load handling, which system includes several load platforms, such as RoRo, terminal, industrial cassettes and/or like, and one or several pulling devices, being separate or equipped with a lifting transportation rear part or coupled with a lifting transportation carriage, or AGV- devices. The system is meant for discharging of load, such as containers or like in a ship at a container port or like onto load platforms, in order to discharge the load furthermore from the load platforms when being transported to a discharging station for further handling of the load and furthermore to load the empty load platforms when being transported to a loading station in order to reload empty load platforms for reloading of a ship that is going to leave the container port or like.
In the purpose described above e.g. in ports or industrial environments it is nowadays due to cost savings known to use diesel operated pulling devices, either being equipped with a built-in lifting transportation rear part, the devices being steerable manually or automatically like so called AGV (Automatic
Guided Vehicle) -devices, or devices to be coupled with separate lifting transportation carriages by a so called fifth wheel arrangement. This kind of lifting transportation devices have typically hydrostatically operated actuators for the lifting of load existing on the lifting transportation rear part or carriage. The actuators being used typically comprise actuator organs in connection with wheel assemblies of the lifting transportation rear part or carriage and/or on the principle shown in figure Ib in connection with an articulation assembly in the fifth wheel arrangement of a separate pulling device, such as hydraulic cylinder arrangements in order to alter a ground clearance of the lifting transportation rear part or carriage. The load platforms for their part have so called lower tunnels, in which the lifting transportation rear part or carriage can be driven when being lowered. The height of the tunnel in the load platform depends on the type of the cassette being used at any given time, whereby the tunnel height of cassettes being used particularly in maritime operations, is minimized. In figure 2a is shown a typical load platform, the dimensions of which vary depending of its operational purpose typically within the following limits:
- Ll: 2133 mm - 2700 mm,
- L2: 2359 mm - 3000 mm,
- a: 50° - 60° and - h: 703 mm - 1000 mm.
On the other hand, as shown in figure 2b, it is also naturally possible to utilize a load platform equipped with wheels .
Nowadays environmental hazards are still involved with the arrangements described above due to operations based on diesel, in addition to which the energy store of the pulling device must always be dimensioned particularly with a view to lifting and transportation measures of the load to be handled at any given time. This is why when a pulling device, being equipped with a lifting transportation rear part or coupled with a lifting transportation carriage, moves without a load, it has continuously an extra amount of mass along. So, an energy capacity, which this kind of a lifting transportation device is carrying continuously, must be dimensioned with a view to a total energy consumption of the device's operating period at any given time, which would require nowadays, if being carried out electrically, a set of accumulators of disproportionately large size. It is an aim of a system according to the present invention to achieve a decisive improvement in the problems described above and thus to raise essentially the level of prior art. In order to carry out this aim, the system according to the invention is mainly characterized by that a load platform belonging to the system is equipped with an energy store, such as a set of accumulators, a super condensator assembly and/or like, being dimensioned particularly with a view to operations to be carried out by a pulling device, being separate or equipped with a lifting transportation rear part or carriage, or an AGV-device, loaded with the load platform, particularly in order to enable an electrically or electro-hydraulically operated lifting transportation equipment.
As the most important advantages of the system according to the invention may be mentioned simplicity and efficiency of constructions enabled by the same as well as of its use, whereby environmental hazards and energy consumption can be significantly decreased and load handling e.g. in port or terminal use etc can be made much more efficient. Thanks to the system according to the invention it is first of all possible to make a lifting transportation equipment electrically or electro-hydraulically operated without a need for solutions operated by combustion engines. Thanks to the invention, it is furthermore possible to minimize energy consumption of a lifting transportation equipment being moved without a load, because the invention enables producing the pulling device advantageously with a set of accumulators and/or a super condensator assembly, being dimensioned only with a view to driving power transmission that is needed when the device moves without load. Other advantageous embodiments of the system according to the invention have been presented in the dependent claims related thereto.
In the following description the invention is being illustrated in detail with reference to the appended drawings , whereby
in figure 1 is shown an advantageous operating principle of the system according to the invention when being exploited particularly in a container port or like,
in figures 2a and 2b are shown first of all a typical load platform to be used in the system according to the invention and on the other hand, as an alternative to the above, a load platform equipped with wheels,
in figure 3 are shown an advantageous pulling device, equipped with a lifting transportation rear part, and a load platform, being used in the system according to the invention.
The invention relates to a system for load handling, which system includes several load platforms 1, such as RoRo, terminal, industrial cassettes and/or like, and one or several pulling devices, being separate or equipped with a lifting transportation rear part 2a or coupled with a lifting transportation carriage 2a, or AGV-devices. The system is meant for discharging of load, such as containers or like in a ship at a container port or like, onto load platforms, in order to discharge the load furthermore from the load platforms when being transported to a discharging station I for further handling of the load and furthermore to load the empty load platforms when being transported to a loading station II in order to reload empty load platforms for reloading of a ship that is going to leave the container port or like. A load platform 1 belonging to the system is equipped with an energy store 3, such as a set of accumulators, a super condensator assembly and/or like, being dimensioned particularly with a view to operations to be carried out by a pulling device 2, being separate or equipped with a lifting transportation rear part or carriage 2a, or an AGV-device 2, loaded with the load platform 1, particularly in order to enable an electrically or electro-hydraulically operated lifting transportation equipment.
As an advantageous embodiment of the system according t the invention, the pulling device 2, being separate or equipped with a lifting transportation rear part 2a, is equipped with a basic energy store 4, such as a set of accumulators, a super condensator assembly and/or like, dimensioned particularly with a view to driving power transmission for moving without load, thanks to which particularly energy consumption of an unloaded pulling device can be decreased significantly when compared to present solutions.
The load platform 1 and the lifting transportation rear part or carriage 2a are as a further advantageous embodiment with reference to figure 3 provided with coupling means 5 in order to couple the load platform's 1 energy store 3, such as a set of accumulators, a super condensator assembly and/or like, electrically with a power transmission arrangement of the lifting transportation rear part or carriage 2a, being controlled advantageously for example from the pulling device's cabin, and/or in order to transmit energy between the same and the basic energy store 4 of the pulling device for example for charging of the basic energy store or for a corresponding purpose.
Furthermore particularly with reference to figure 1, the discharging station I, loading station II and/or some other handling station for the load platform is /are provided with a charging assembly 6; 6a at least for charging of the energy store 3 in the load platform 1, such as a conductor assembly 6a through contact surfaces 6b in the load platform. In this context it is furthermore advantageous to get also the charging of the basic energy store 4 of the pulling device 2 to get coupled simultaneously when the pulling device or the lifting transportation carriage coupled therewith is being coupled with the charging assembly 6; 6a existing in the discharging station I and/or in the loading station II. It is also possible to include in the system a charging station of its own for the pulling device, where the pulling device can be charged when the electric charge of its basic energy store is decreased below an allowed limit.
Thus, for example an automatic AGV-device 2 as shown in figure 3 or in the other hand a pulling device 2, equipped with a cabin as shown in figure 2b, is provided advantageously with monitoring means for monitoring of the status of the basic energy store 4 and the energy store 3 in the lifting transportation rear part or carriage 2a.
Furthermore as an advantageous embodiment particularly with reference to figure 3, the coupling means 5 are arranged by couplers that get coupled automatically between the load platform 1 and the lifting transportation rear part or carriage 2a, which couplers couple together the electric circuits of the basic energy store 4 and the energy store 3 when the loading platform is placed on the lifting transportation rear part, carriage or AGV-device. In this context, it is furthermore possible to arrange the load platform 1 and the lifting transportation rear part, carriage 2a or AGV-device to get coupled with each other by suitable e.g. inductive or capacitive arrangements that get coupled electrically in a non-contacting manner.
As a further advantageous embodiment, the energy store, such as a set of accumulators, a super condensator assembly and/or like, in the load platform is dimensioned at least with a view to operations related to moving of a loaded load platform between handling stations, equipped with charging assemblies 6. On the other hand, the basic energy store 4, such as a set of accumulators, a super condensator assembly and/or like of a manual pulling device 2 or of an AGV-device 2 is dimensioned at least with a view to energy consumption between handling stations, equipped with charging assemblies 6, when being unloaded.
It is clear that the invention is not limited to the embodiments shown or described above, but instead it can be modified within limits of the ground idea of the invention according to the operating purposes and embodiments at any given time within the scope of protection of the enclosed claims. So, it is first of all clear that the system according to the invention can be exploited for intermediate storing and further processing of products in environments concerning e.g. steel, paper or concrete industry, whereby there may be more discharging stations, loading stations and/or separate charging stations than shown in the appended drawings. Depending on the place of utilization, the load to be handled at any given time varies typically from about 30 tons up to 150 tons, which is why in a system according to the invention it is naturally possible to exploit very many kinds of techniques in carrying out the energy stores.
