Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a container vehicle consisting of a vehicle having a frame and a container, in which the container is held on the vehicle frame, and the container is unloaded from the vehicle by using a loading/unloading device. as well as in a form that can be stacked on the vehicle again.

The importance of containers in transporting goods, cargo, and other goods is increasing year by year.

The advantage of using containers is that the loading and unloading of goods and cargo to be transported can be carried out without the need for a transport vehicle. That is, during loading and unloading work, the container is unloaded from the transport vehicle by the unloading device, so the transport vehicle, for example, the truck,
It becomes possible to use it for the purpose of cutting.

There are already many known examples of loading and unloading devices for unloading containers from a transport vehicle and stacking them on the transport vehicle again.

According to German Patent No. 1 650 545, a loading and unloading device of this type has two piston-cylinder units which are arranged on either side of the container and can be pivoted in a plane.

The upper ends of these units form a hinge, whereas one of the lower ends of each unit is supported immovably, and the other, for example, relative to the frame of a transport vehicle.
Slidably pivoted.

The lower ends of the piston, cylinder, and unit are pivotably supported by seven frames and abut against support rails that can be selectively locked to the frame.

Between the hinge and the center of the loading surface, removable support pipes are arranged on both sides so as to be pivotable transversely to the longitudinal direction of the vehicle.

These support rails, according to German Patent Application No. 1755352, can be designed and made to be pulled out telescopically, and at their outer ends are provided with:
A pivotable folding support is provided.

A container mounted on a transport vehicle is lowered by means of this crane-shaped device onto another vehicle, onto a frame, or directly onto the ground in a circular trajectory of movement. The container will then be located on the side of the transport vehicle. What about the loading movement? :, is performed in the opposite direction.

2 Loading and unloading devices of this type are 1 mechanically complex and therefore require considerable expense in their construction and maintenance.

To improve a type container car, simplify the structure of its loading/unloading device, and significantly facilitate loading/unloading of containers.

In order to solve this problem, according to the present invention, the loading and unloading device is provided with a frame structure that can be connected to the vehicle frame and is located at the unloading point of the container, and on the frame structure, It is possible to move the container by almost horizontal movement.

In contrast to known loading and unloading devices, the container according to the invention must initially only be moved horizontally to the unloading point during the unloading operation.

This container can, for example, be slid onto a skeletal structure placed beside a vehicle, such as a truck. In this case, support rails are arranged between the frame of the truck and the frame structure 1 and the container is pulled onto the frame structure or trestle, for example using a cable winch.

Note that loading the container from the frame structure onto the truck is performed in the reverse order. Therefore, only the frictional resistance of the container needs to be overcome during the unloading and loading process. Moreover, this frictional resistance can be reduced by taking measures such as, for example, rolling the container on rollers.

The frame structure for the container to be unloaded may be a separate cradle installed at the unloading point, or it may be a frame structure connected to the frame of the transport vehicle. The latter can either remain at the unloading point or be removed after the container has been lowered to the ground.

It is advantageous if the loading and unloading device is provided with a telescoping device which is rigidly connected to the vehicle frame.

In this case, the container remains locked and stationary on the frame-like telescoping member during driving. After the frame-shaped telescoping device has been mounted, it is possible to move the container outwards (so-called sexual movement) with the container. When the unloading point is reached, the container is supported from below so that the telescoping device can be retracted again and is ready for receiving and unloading another container.

It is also possible to design the frame-shaped telescoping device in such a way that it can be lowered along the frame of the transport vehicle. In that case, when the container is delivered in the direction towards the unloading point, the supported telescoping device is lowered until the container rests on the ground. that time,
The telescoping device is self-propelled and lifted into its starting position on the vehicle frame.

The telescoping unloading device according to the invention can be used on the side of a transport vehicle for unloading containers when the outward direction of the telescoping device is located transversely to the longitudinal axis of the vehicle frame. I can do it. When the telescoping device is swiveled so that its column direction is in the direction of the longitudinal axis of the vehicle frame, the containers can be unloaded directly behind the transport vehicle.

A container vehicle having a loading/unloading device configured according to the present invention is used to unload a lightweight container, that is, a container with a conventional crane-type loading/unloading device that suspends the container, to a container suspension point, and then to place the container on the transport vehicle again. It can also be used for containers with a special lightweight structure that can be used.

In the container car according to the invention, since the containers are slid horizontally, the forces on the containers act only in the plane of the reinforced base frame, and no forces are exerted on their superstructure. do not have.

The invention will now be described in detail with reference to several exemplary embodiments illustrated in the accompanying drawings: FIG. 1 shows a truck +1+ with an elongated vehicle frame (2). ``In this case, it is possible to accommodate two containers (3) in the vehicle.

Each container (3) is mounted one after the other on the vehicle frame (2). Vehicle frame (21 includes each storyboard + (
One loading and unloading device (4) is provided for every 31.

In the case of FIG. 1, only the loading/unloading device (4) belonging to the front container is schematically shown, and when unloading the container, it is used from the side of the vehicle. The rear container (3) can also be unloaded by a similar unloading device, but the unloading then preferably takes place in the longitudinal direction of the vehicle.

In other words, in this case, the container is unloaded from the rear of the truck (1).

FIG. 6 shows a loading/unloading device for unloading containers from the side. This loading and unloading device (4) has a telescoping frame (5) which is rigidly connected transversely to the frame axis and to each other by cross beams (7). It consists of two molded rails (6), each with two molded rails (81 (9)). In this case, the latter molded rails (9) are Beam Q
O) are connected to each other by

While an intermediate molded rail (8) slides within a first molded rail (6) rigidly connected to said frame (5).

The second forming rail (9) slides within the intermediate forming rail (8).

The telescoping frame (5) can be folded in and out (retracted and extended) by means of a hydraulically actuated cylinder device. One end of the old cylinder device is
The other end of the cross beam (7) is connected to another cross beam (121), which itself connects the front ends of both molded rails (9) to each other.
is connected to.

Both forming rails (9) each have two mounting tables 031, and containers not shown in this figure are placed on these four mounting tables 03.

When the telescoping frame (5) is retracted.

The container is centered around its vertical axis, and is attached to the vehicle frame (2
1, and in this position it is locked by a locking member (not shown).

The individual movable profiled rails (81(9)) are further connected by further cross beams Q4) Q51, so that they each form a rigid frame. The four mounting tables OJ provided on the molding rail (9) are each connected to one elevating cylinder ae, and can be lifted and lowered by these cylinders.

Underneath the vehicle frame (2) in the area of the immovable molded rail (6) located in the front when viewed from the plane of the drawing in FIG. Flat 0′? ) is connected to a collapsible column α.

When unloading a container placed on a truck, first, the support column 08 is rotated toward the ground. In this case, the struts can be externally attached or extended laterally, as indicated by broken lines in FIG. The container is then unlocked from the vehicle frame (2) and the cylinder device 0υ is activated.

The container stationary on the mounting table Q31 is slid laterally when the telescoping frame (5) is moved.

The weight of the container acting downward is stopped by the support column α. When the telescoping frame (5) is fully extended, the container is located at the unloading point as shown in FIG.

Next, a lifting device Q consisting of a cylinder for the mounting table Q31
61 is protruded, the entire container is lifted slightly. At this time, in the container frame,
It is best to connect the pallet legs.

Thereby, in the next step, the lifting device (16) will be retracted slightly until the pallet legs Ql touch the ground and support the container. When the lifting device (16) is further retracted, the mounting table Q31 is separated from the container, so that the telescopic nib type frame (5) can move on its own.

Thereafter, the strut Q81 is also folded back and optionally retracted. The container car is now ready to accommodate another container. As shown in FIG. 2, it is also possible to provide stairs for loading containers.

The work of stacking the unloaded containers onto the truck again is
This is done in the reverse order as stated above.

That is, first, the prop 081 is brought out and erected on the ground, then the telescopic frame (5) is sent under the container (3), and finally the lifting device Q61 is activated to raise the container (3). ).

The container (3) is constructed by removing the g cash register 1 leg 0 and then retracting the telescopic frame (5).
It is then transported onto the second rack and locked there. Pillar a~
When folded and possibly retracted,
The container car becomes ready to travel.

FIG. 4 shows a side view of another unloading device (4a). This loading/unloading device is also constructed of a telescoping frame (5a) as in the previous embodiment. The telescoping frame (5a) again consists of six pairs of molded rails (6a) (8aX9a). The forming rail (6a) is rigidly connected to the vehicle, while the other forming rails (8a) and (9a) are telescopically movable and self-propelled, as described above.

However, this telescoping frame (5a) U is different from that in the previous embodiment, and the vehicle frame (2(
is located below. When driving, the container (3
)'s bottom (4 parts) are connected to the vehicle frame (2).
It is placed on top of the book.

This container is locked by a locking member (43).

At the bottom of the container (4I), as in the container (3) already occupying the sexual position on the right side of FIG.
A lifting device (through which a lifting device (491) which can be raised and lowered is engaged) has a loading table (451) (the fence is also in this case fixed to the molded rail (9a)).

When unloading this container (3) from the container car,
As in the previous embodiment, the side posts (not shown in this figure) are first rotated outwardly to unlock the container by the locking member 143.

Next, the mounting table (four of which can be retracted) located at the rear of the telescopic frame (5a) when viewed in the external direction.
It is located below the lower limit of the vehicle frame (2). In this state, the telescopic frame (5
When a) is moved, the container, which is still connected to the molded rail (9a), is carried away via the mounting table (49) in front of it.To support this carrying movement, the horizontal beam (42 A roller (40) supporting the bottom (4υ) of the container can be provided at the bottom of the container.

The telescoping frame (5a) is moved until the rear mounting table (451) reaches the outside of the frame and the container (3) is still on the horizontal platform (4). Immediately, the rear mounting table (4'5) is lifted up by the lifting device (44) and brought into engagement with the bottom (41) of the container again.

- The telescoping frame (5a) is then completely erected. This elevating device (44J) is connected to hydraulically operated support legs (4?) that are lowered until they reach the ground when the telescopic frame (5a) is moved, so that the container (3) The total weight is on this support leg (4
7) Act on.

The bottom (41) of the container (3) is provided with a supporting leg (48). The distance between the lower end of the supporting leg (41) and the bottom (41) provided by the supporting leg (rail) is determined by the telescopic frame (5a). The support legs are rigidly connected to the container, but alternatively short support legs may be connected to the container after the container has moved. .

By the way, the mounting table (49 is a hydraulic cylinder type lifting device (
When lowered by the telescope, a supporting leg (marked 4 or another supporting leg) will protrude from the top of the telescopic frame (5a) further below the lower surface of the frame.

The entire telescoping frame (5a) is then allowed to lower. For this purpose, the inner molded rail (6a) in the telescoping frame (5a) is guided by two guiding ξ-ibs (49) which can be lowered to the ground by means of a hydraulic cylinder 60). These hydraulic cylinder sides are fixed to a horizontal beam (421).

In FIG. 4, two positions in one guide pipe are shown. In this case, the solid line indicates:
The lowered guide pipe, shown in broken lines, is connected to the crossbeam (6a) via its saucer foot I5]).
is a recessed guide, ove, which is crimped onto the vehicle frame (2).

When the guide/ξ Eve (49) is lowered to the ground, the support leg (47) attached to the molded rail (9a) can be retracted by the lifting device (hydraulic cylinder) (4'41), so that the tele The entire scope frame (5a) is lowered.The weight of the container (3) is
) and thus the forming rail (6a) acts on the container (
3), the telescoping frame (5a) lowers uniformly to the ground.

In this way, the telescopic frame (5a) becomes capable of retracting the bottom of the stationary container. Then, when the hydraulic cylinder 6 is actuated, the entire telescoping frame (5a) returns to the vehicle frame (2) shown in FIG.
is lifted into the starting position below.

Telescopic frame (5a) All vehicle frames 12
The advantage obtained by the arrangement under the + is that the entire telescoping frame (5a) only has to be lowered very slightly in order to lower the container (3) to the ground.

In FIG. 5, a further unloading device (4b) is shown. This loading/unloading device (4b) is connected to the vehicle frame (2
), it has two horizontal beams 521 extending laterally and rigidly connected to the frame (2), and during driving, the container (not shown in the figure) is attached to these horizontal beams. placed on top. A locking member (not shown) is provided for locking the container.

The front ends of both horizontal beams are connected to extension beams that can be rotated freely relative to the plane of the vehicle frame. Each of the extension beams 63 has two mounting tables 6a at its free end, and within each of these mounting tables 64), a lifting device (cylinder) 159 is provided.

Integrated right.

During running, the extension sill 5■ is rotated under the container placed on the side beam, and at that position is locked to the frame by the locking member 6e or locked to each other. be done.

To unload the container: - Swivel the extension beam 53) into the extension of the horizontal beam 5; In this case, the extension burr (5
The free ends of 3) can still be connected by a cross beam, not shown.

As mentioned in the above embodiments, the vehicle is still supported by lateral struts, which are not shown here but correspond to the aforementioned struts 08.

Thus supporting leg 5? ) can advance from the lifting device r5 and reach the ground, so that the externally rotated extension beam 153) forms an immovable platform for the container to be unloaded. This container is then unlocked and
For example, by using a cable winch, the container center is pulled onto the extension beam 153) until it is supported by the support legs 6ηr.

It is also possible to arrange rollers on the back side of the container. In that case, the rollers are connected to the horizontal beam 52 and the extension beam (
), the frictional resistance required to move to the unloading location can be kept to a low level.

For final unloading, ``As shown in the first embodiment, lift the container using the lifting device -651 using the opening of the loading table (54), and then place the support legs on the container. By attaching it, the container can be easily unloaded.

In this case, by subsequently folding the support base (54) further inward, the extension bar G moat can be swiveled back into its starting position.

In addition, in order to increase the length of these extension beams, it is also possible, for example, to configure them as two telescopic rods each consisting of two molded rails.

FIG. 6 shows a loading/unloading device (4
C) is shown. In this case, the container (3) is supported by a horizontal beam (6υ) on the vehicle frame (2) of the container car, and is locked by a locking member (6υ).

A frame structure (63) is installed at the desired installation position of the container to be unloaded. The frame structure is connected to the frame structure (6
3) is connected to the end facing. In order to reduce frictional resistance during sliding, this container (3) is equipped with a 6D horizontal beam.
A roller (65) abutting the top is disposed.

A cable winch (661) is further coupled to the cross beam (6I).The cable (6) is wound around a deflection roller provided at the outer edge of the set structure.
It is then hung at the bottom of the container at the sign @Yu.

Unlock the container (3) and install the cable winch @Oi.
When actuated, the container (3) is pulled onto the framework @9 via the rollers, the transverse beam [F]υ and the guide bar. Note that the container (3) can also be locked here again.

Once the cable (6η) has been removed and the guide beam has been removed, the next container can be loaded into this container car.In order to load the container from the frame structure (6) into the container car, the cable @ The winch is hung on the container on the side facing the field, and the container is pulled onto the crossbar υ via the guide beam.In this case, the container can be locked with a locking member for removal.

In the loading and unloading devices described so far, it has been assumed that containers are loaded and unloaded from the side of the container car, but the container car loading and unloading device according to the present invention loads and unloads containers from the rear of the container car. It is also possible to rearrange the location as appropriate so that loading and unloading can be carried out from there. Such a structure is
Usually used for rear containers (Figure 1). This is because it is often impossible with existing vehicles to unload containers from the rear from the side.

With the container car according to the invention, lightweight containers can be unloaded and reloaded onto the container car in a simple manner. The energy required in this case is relatively low, since the transport of the containers from the container car to the unloading point takes place primarily by horizontal sliding movements.

Horizontal movement of the container can be carried out hydraulically or by means of a simple cable winch. It should be noted that this second possibility, namely the use of a cable winch, can also be applied to the telescoping frame according to the embodiments described. In this case, the cable of the winch must be appropriately wound and guided around a plurality of deflection rollers in order to enable the telescoping frame to move and move itself (pull-in and pull-out).
