Description

Easel truck

The invention relates to the handling of containers in ports and terminals, especially with the help of the so-called trestle truck system. In great detail, the invention relates to an easel truck, to which a portal body comprising essentially vertical support pillars and an upper body that connects them at the top and resting on what are the devices of Lifting necessary mounted to lift and hold containers, and on each side of the easel truck at the lower end of the support pillars there are wheels that transport the portal body, through which between both the front and rear support pillars Transversal lifting beams of the movable easel truck are arranged in the vertical direction as well as the necessary means for grabbing the containers.

An easel truck with these characteristics is known from DE 103 55 946 A.

The invention is thus to produce the movement and transport of the cargo with the help of the containers. Cargo goods are conveniently transported in containers from the dispatcher / manufacturer of the goods directly to the buyer / recipient without any intermediate stages. When the transport distances are long, the critical transport points are located at those points where the way of transporting the containers changes, such as in the ports, where large quantities of containers have to be unloaded, placed in intermediate storage and recharged to Another mode of transport. In the ports the objective is to achieve loading / unloading times as short as possible, because having the boats parked on the dock raises the costs and costs will be raised even more if the loading / unloading is delayed for some reason, thus causing the ship in the scheduled line service. If a ship has to unleash the lost time of its service line, it will have to use a higher and more economical travel speed, by means of which its fuel consumption and costs will be greater than those calculated. Thus, the loading and unloading of the ship must occur as soon as possible and without any additional delay or affectation.

To load and unload ships in the ports they use a port crane, which lifts the containers either directly from trailers pulled by a vehicle or under the crane, where they have been taken, for example, by a trestle truck or by A transport trolley. In the easel truck system, the easel truck or transport truck usually transports the port containers between the port crane and the storage area. The cranes of the containers on the other hand are devices of a large size, and due to their large size the process of moving them during these work rotations is difficult and slow. When containers move directly to a trailer or from a trailer, the port crane can handle only one container at a time. When an easel truck system is used, such solutions have already been developed, where the port crane can handle or lift two containers at the same time, so that the containers are placed in parallel while they are hoisted. When a ship is unloaded, the port crane leaves the containers side by side under the crane waiting for transport. Correspondingly, when loaded, the containers must be left exactly parallel under the crane, so that the port crane can pick them both up at once. Until now it has not been possible with the easel trucks, or correspondingly, with the transport trucks to handle two parallel containers at the same time, for which reason it has not been possible to fully benefit from the port cranes possibly to handle two containers.

The easel truck must have a structure that is as favorable as possible for development in another environment and in equipment that relates to the environment. In order to achieve that objective as well as other objectives arising from the description of the invention, the invention is mainly characterized in that the means for grasping the containers comprise two container separators, which are suspended from the lifting beams and are arranged in parallel in relation to the steering direction of the easel truck, and that the lifting devices for lifting and holding the containers comprise a common lifting mechanism, which is connected through the lifting ropes or other means of Lifting the lifting beams to handle the containers in parallel at the same time.

An easel truck according to the preamble of claim 1 is known from EP 20 48 106 A, which is an intermediate document according to Art. 54 (3) of the EPC.

The side transfer trolleys, of which the container separators are suspended so as to allow the difference in height, are mounted for the container separators to the lifting beams of the easel truck for movement along the beams hoisting The lateral transfer cards are equipped with actuators, which are used to separately transfer the lateral transfer trucks and the container separators suspended therefrom in order to separate the containers from each other and, correspondingly, move them closer to each other. other.

The lifting beams are adequately supported in the direction of the horizontal plane on the support pillars of the easel for movement in the vertical direction. The lifting beams are preferably supported by their two ends on the pillars that support the easel truck through sliding part structures that allow movement in the vertical direction.

The points where the lifting ropes are attached to the lifting beams are preferably arranged in the area of the ends of the lifting beams in order to allow handling of one container at a time.

The easel truck can be a stacking easel truck or a low transport truck equipped with longitudinally controlled container separators to handle containers of different sizes. The separators of the easel truck container can be twin separators, by means of which it is possible for the easel truck to handle four containers at the same time.

The invention provides significant advantages compared to the prior art. The main advantage of these advantages is, for example, the considerably better efficiency, because in the easel truck system according to the invention it is possible to transport and correspondingly stack two containers parallel to the storage area at the same time. The savings achieved especially in energy and value costs are significant. At the same time the storage density is increased, because it is not required to leave a driving lane now for the wheels of the easel truck between each container row, but instead between each second row of container. Other advantages and features of the invention subsequently arise from the following detailed description of the invention.

In the following, the invention will be described by way of example when referring to the figures in the final drawings.

Figure 1 is a complete view of one side of the easel truck according to the invention.

Figure 2 is a corresponding view of the front of the easel truck shown in Figure 1.

In the figures of the drawings, the general reference number 10 indicates an easel truck. The easel truck 10 comprises a portal body 11, to which the essentially vertical support pillars 13a, 13b, 14a, 14b belong, and the upper body 15 that connects them at the top. On each side of the easel truck 10 at the lower end of the support pillars 13a, 13b, 14a, 14b, are the wheels 12 that support the body of the portal 11. The operator cabin of the easel truck 10 is indicated by reference number 29 in the figures. As illustrated in the drawing figures, especially in Figure 2, the basic features of the easel truck 10 are preserved in the structure of the easel truck according to the invention, but the body of the portal 11 of the forklift easel 10 according to the invention becomes essentially wider than the prior art solutions such that between the pillars supporting the body 13a, 13b, 14a, 14b, it has been possible to adjust them in two parallel container separators 16 , 16a, 16b, by means of which it is possible with the easel truck 10 to handle the parallel containers at the same time. The figures in the drawing show the so-called low transport truck, but it is very obvious that a structure similar to the high stacking trucks can also be applied.

A lifting mechanism 18 is mounted to the upper body 15 of the body of the portal 11 of the trestle truck 10, which is shown completely schematically and is connected, for example, by ropes 28a, 28b to the transverse lifting beams 20, which are located between the front and the corresponding rear support pillars 13a, 13b, 14a, 14b, and of which the container separators 16, 16a, 16b are suspended. Figure 2 shows only the front lifting beam 20 located between the front support pillars 13a, 13b, but it is obvious that a similar lifting beam 20 is also mounted between the front support pillars. In the solution according to the invention, two container separators 16a, 16b are mounted to rest on the lifting beams 20 in parallel in relation to the steering direction of the easel truck 10, and these container separators move thus in the height direction (raised and lowered) with the help of a common lifting mechanism 18.

The lifting beams 20 thus extend in the transverse direction of the easel truck 10, and in order to support them horizontally there are sliding structures 27a, 27b or corresponding guides arranged between the lifting beams 20 and the supporting pillars 13a, 13b, 14a, 14b, whereby the lifting beams 20 get their required guidance from said support pillars 13a, 13b, 14a, 14b. The structures of the sliding devices 27a, 27b, or other such structures are used in relation to both the front support pillars 13a, 13b, and the rear support 14b. It may also be advantageous to use structures with sliding elements 27a only on one side of the easel truck 10, while on the other side of the support of the lifting beams 20 on the support pillars 13b, 14b, they may be more free in the lateral direction Especially when heavy loads are lifted, any bending of the structures will thus not cause any clogging between the lifting beams 20 and the supporting pillars 13a, 13b, 14a, 14b. Each lifting beam 20 is connected by lifting ropes 28a, 28b to the lifting mechanism 18 resting on the upper body 15 and with the help of which the lifting movement is carried out. It is advantageous to arrange the attachment points of the lifting ropes 28a, 28b to the lifting beams 20 near the ends of the lifting beams 20, by means of which it is possible for the easel truck 10 to handle only one container a the time The lifting mechanism is not described in greater detail in this context and can be, for example, a structure and operation of those described in the previous FL Patent 107142.

The lateral transfer trucks 17a, 17b are mounted for parallel container separators 16a, 16b on transverse lifting beams 20, such that there are two of them both in the front and rear lifting beam

20. The lateral transfer trucks 17a, 17b are mounted to rest on the lifting beams 20 such that they can be moved in the transverse direction of the easel truck 10. The lateral transfer trucks 17a, 17b are equipped with actuators, for example, with hydraulic cylinders 19a, 19b shown in Figure 2 or with the corresponding equipment. Actuators of other types can also be used, and an electric impeller (for example, a combination of an electric motor and a transmission chain) can be mentioned as a possible solution. The container separators 16a, 16b are suspended from the side transfer trucks 17a, 17b with the aid of suitable suspension means 24a, 24b, for example, with the help of suitable chains and guides or other such such that the container separators 16a, 16b can move in the vertical direction in relation to each other. By this, when parallel containers 1, 2 are handled, they do not need to be at the same height, as the figures in the drawing clearly show. If the adjacent containers 1, 2 are at different height as shown in the figures (for example 8 'and 91/2') then when the containers are collected the container separator 16a, it will first hit the highest container 1, by means from this it would be possible to lower the container separator 16b to an additional one in order to grab the lower container 2. The suspension means 24a, 24b allow this to a certain limit.

Thus, the lateral transfer trucks 17a, 17b, can be moved in the transverse direction along the lifting beams 20 with the help of their actuators 19a, 19b. With the help of said lateral transfer cards 17a, 17b it is possible to separate adjacent containers 1, 2 from each other when required.

In the figures of the drawing, the reference marks 25, 26, 25a, 25b indicate the lifting shafts of the container separators 16, 16a, 16b, with which the containers 1, 2 are gripped in the upper corners of the containers . Container separators 16, 16a, 16b are controlled longitudinally so that they can be used to handle at least the 20 ‘, 45’ containers in use today. Containers located in parallel do not need to be of equal length, but the easel truck 10 can be used for handling parallel to one of 20 'and 45' containers at the same time. Although the figures are not shown, as container separators 16, 16a, 16b it is also possible to use the so-called twin separators, which are equipped with middle handles in addition to the lifting handles located at the ends. With one of such twin separators it is possible to simultaneously lift and move two 20 'containers located one behind the other, by means of which the easel truck 10 according to the invention when equipped with such container separators can handle Four 20 'containers on a trip.

In the foregoing, the invention was described by way of example with reference to the figures in the final drawings. However, the invention is limited to the examples shown in the figures, but the different embodiments of the invention may vary within the scope of the inventive idea defined in the final claims.
