Description

Cargo fixing for pick-up trolleys

The present invention relates to a soft transport car with at least one loading platform for receiving a cargo which is pivotable about a pivot axis extending in the vehicle longitudinal direction in a transport position and a loading position, and at least one elongate charge-holding device for fixing the cargo on the loading platform, said the charge-holding device has at one end a holding element, which interacts releasably and positively with the load for fixing.

Such soft transport car are well known, for example from the document EP 0 617 169 B1. These are trolleys with rail chassis, which are designed to handle wide loads such as track and to transport switch parts. The loading platform provided for this purpose is pivotally mounted on the trolley frame, so that it can be pivoted from a horizontal loading position into an inclined transport position. In this inclined transport position, it is necessary to fix the cargo such as track and switch parts, etc., in particular to fix against slipping down.

For this purpose, elongated charge-holding devices are provided, which are on the one hand fixed to the loading platform and on the other hand cooperate, for example, hook-shaped holding elements with the load to produce the necessary fixation. Since the load can be different, it is necessary for each charging process to adapt these charge-holding devices according to the load.

In the charge fixation results in both the loading and unloading the problem that the loading platform must be entered. Since a fall protection for procedural reasons can not be realized with reasonable effort, there is therefore danger of falling for the active persons. In addition, the attachment and detachment of the individual holding elements of the charge-holding devices requires a large amount of labor.

Against this background, the object of the present invention is to develop the aforementioned soft transport car so that a simplification and relief is achieved in particular when solving the charge fixation during the unloading process on a construction site. Another object is to avoid the loading platform being loaded during unloading at the construction site.

The object underlying the invention is achieved in the aforementioned soft transport car in that the charge-holding device at its other end pivotally about a running in the car longitudinal direction

Pivot axis and displaceable in a direction perpendicular to the pivot axis (fixing direction) is attached to the loading platform. That is, in other words, that the charge-holding device is movably connected to the loading platform, so that a release of the fixation without going to the loading platform is possible by the charge-holding device in the fixing direction, that is displaced perpendicular to the pivot axis. Preferably, the entire charge-holding device is displaceable. The length of the charge-holding device is therefore not changed when fixing and releasing.

By this displacement, the holding element from the load, and the pivotal configuration then allows it, that the holding element moves by gravity down away from the load.

In a preferred embodiment, the other end of the charge holding device is connected to a drive unit for the displacement in the fixing direction.

Such a drive, such as a hydraulic cylinder, allows on the one hand the release of the fixation and on the other hand, the clamping and fixing of the holding element, so that the holding element cooperates positively with the load.

In a preferred embodiment, the drive unit has a running in the carriage longitudinal direction of the drive rod and a drive, wherein the drive rod is rotatable about a pivot axis which is parallel and offset from the drive rod. Preferably, the other end of the charge retainer is releasably attached to the drive rod.

This means in other words that the charge-holding device is displaceable over the drive rod in the fixing direction, wherein the position of the charge-holding device is variable to the drive rod. That is, the other end of the charge holding device is arbitrarily attachable along the drive rod extending in the carriage longitudinal direction. The advantage of this measure is the fact that the charge holding device can be mounted very flexible in the vehicle longitudinal direction.

In a preferred embodiment, the charge-holding device is designed so that the length between the two ends is adjustable. Preferably, the charge-holding device has a first rod-shaped element and a second rohrformiges element, wherein the first element is received in the second element displaceable and fixable. More preferably, the first element has a plurality of openings distributed in the longitudinal direction for receiving a locking element, and the second element has at least one opening for receiving the locking element, so that the first element on the second element in different positions on the locking element can be fixed. More preferably, the opening of the second element is designed as a slot, so that the locking element is displaceable within the slot, and a displaceable support member is provided which fixes the locking element in a selectable position within the slot at least in one direction. More preferably, the support element is designed as a rotary element, for example as an adjusting nut, which is displaceable by a thread on the second element in the longitudinal direction by turning. More preferably, the locking element is designed as a bolt which can be pushed through the slot and the opening in the first element.

By these various measures, the charge-holding device is adjustable in its longitudinal extent between the two ends, so that they can be preset parallel to the loading platform and transversely to the carriage longitudinal axis preferably in defined stages for securing. A fine adjustment of the longitudinal extent is then possible by means of the rotary member.

In a preferred embodiment, the first element is rotatable about its longitudinal axis. This measure makes it possible that the holding element of the charge holding device can also be fixed to a strut of the loading platform, for example, when no load must be fixed.

In a preferred development, a plurality of charge-holding devices are provided distributed in the vehicle longitudinal direction.

In a preferred embodiment, a stop element is provided on the loading platform, which supports the charge-holding device in a lower pivot position.

That is, in other words, that the abutment member on the loading platform serves to hold and support the cargo holding device after releasing the fixation and the swinging motion caused by the weight downward in a lower position.

It is understood that the features mentioned above and those yet to be explained not only in the particular combination, but also in other combinations or alone, without departing from the scope of the present invention.

Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings. Showing:

Fig. 5 is a schematic representation of a charge-holding device according to an alternative embodiment.

In FIGS. 1 a to 1 h, a rail vehicle, in particular a soft transport vehicle, is shown schematically in a front view and is designated by the reference numeral 10. The rail vehicle 10 has a chassis 12 and a chassis 14, which will not be discussed further on these assemblies. On the chassis 14, a loading platform 16 is pivotally mounted about a pivot axis extending in the longitudinal direction of the car, wherein the pivoting movement via a drive 18, for example in the form of hydraulic cylinders takes place. The loading platform 16 is adjustable between a transport position and a loading position, wherein the transport position in Fig. 1 a is shown and extends obliquely with respect to the horizontal.

Thus, cargo such as track or switch parts etc. can be transported, which would be too wide for horizontal storage for rail transport.

In Fig. 1 a as a load 22, a switch part 24 is shown schematically, which rests on the loading platform 16 and preferably via a plurality of charge-holding devices 30 is fixed in order to prevent slippage of the cargo from the loading platform.

For this purpose, a charge-holding device 30 has a retaining element 32 provided at one end of an elongated element 31, which is preferably designed as a hook element 33 and cooperates with a part 34 of the soft part 24 in a form-fitting manner.

At the opposite end of the charge-holding device 30, an adjusting element 36 is provided, which is fixed to the loading platform 16. The adjusting element 36 makes it possible to displace the holding element 33 in the longitudinal direction of the charge holding device. In other words, that means that the distance between the adjusting element 36 and the holding element 32 is adjustable. This adjustability allows the adaptation of the spatial position of the holding element to different loads.

In Fig. 1 b, the rail vehicle 10 is shown with the loading platform 16 in a horizontal position. This horizontal position is used for loading and unloading of the load 22, where it can be clearly seen that the load protrudes laterally far beyond the permissible width of the wagon. Therefore, in this position of the loading platform a regular transport is not allowed.

In Fig. 1 b, the load 22 is still fixed on the support member 32, so that a discharge is not yet possible. For this purpose, the fixation of the retaining element 32 is achieved by the retaining element 32 is displaced in the x direction to the left, which is clearly visible in Fig. 1 c. The holding member 32 has been released from the positive connection with the part 34 of the switch part 24, so that it, as shown in Fig. 1 d, due to gravity falls down and abuts a support member 35.

Referring now to Figs. 1 b to d, the charge-holding device 30 and in particular the holding member 32 has two movements executed, namely on the one hand a translational movement in the x-direction to the left from the positive connection and a pivoting movement about an axis S1 , which runs in the carriage longitudinal direction. The adjusting element 36 is thus mounted pivotally about the axis S1 on the loading platform 16.

In the next step, which can be seen in Fig. 1 e, the holding member 32 which is rotatably mounted on the element 31 in the adjusting element 36, rotated by 180 °, so that the holding element now points down.

In the next step, which is shown in Fig. 1f, the holding element 32 and thus also the element 31 is translationally displaced in the x direction to the right to to bring it into positive engagement with a corresponding component on the loading platform 16. In this position, the entire charge-holding device 30 is fixedly fixed to the loading platform 16. In Fig. 1 g and 1 h, the rail vehicle 10 is shown in a discharged state, in Fig. 1 h, the loading platform 16 has been brought back into the transport position and the charge-holding device 30 is further fixed to the loading platform 16. Regular transport of the rail vehicle is now possible in this position of the loading platform 16.

Referring to Fig. 2, the mechanism for displacement and rotation of the charge retainer 30 will be explained below. 2, the rear side of the loading platform 16 can be seen in a longitudinal view. Evident are two identically constructed charge-holding devices 30, which are provided spaced apart in the vehicle longitudinal direction.

As already mentioned, the charge-holding device 30 has an adjusting element 36, which comprises a hooking element 38. The adjusting element 36 and the hooking element 38 can be firmly connected to one another, for example by welding, or alternatively can also be connected to one another in an articulated manner, which will be explained with reference to FIG. 5. The suspension element 38 is hook-shaped and serves to be hooked preferably in a form-fitting manner in a rod 40. The rod 40 extends, as can be seen in Fig. 2, in the carriage longitudinal direction, wherein it may be provided over the entire length of the loading platform 16 or only in sections. It is also conceivable that several such rods 40 are provided along the loading platform.

About the suspension element 38, the charge-holding device 30 is thus pivotally held about the longitudinal axis of the rod 40. Furthermore, the suspension element 38 also allows a displacement of the cargo holding device 30 in the vehicle longitudinal direction.

The rod 40 is in turn attached to a rod 42 arranged parallel thereto, the rod 42 being in turn rotatable about the axis S1 at the loading platform. Form 16 is fixed. Corresponding fixing straps are shown schematically in FIG. 2 and identified by the reference numeral 44.

About a drive, not shown, for example in the form of a hydraulic cylinder, the rod 42 can be rotated so that the parallel rod 40 performs a pivoting movement. The two Fig. 1 b and 1 d illustrate this pivotal movement of the rod 40 very clearly. As a result of this pivoting movement, the charge-holding device 30 undergoes a translational movement, which is used for releasing and fixing the holding element 32. The scope of this translational movement is adjusted so that the holding member 32 can completely solve.

In Fig. 2 can still be seen that the holding member 32 cooperates with a corresponding element 46 of the loading platform to fix the charge-holding device 30 to the loading platform 16.

In order to be able to adapt the charge holding device 30, in particular the position of the holding element 32, to different loads, the adjusting element 36 has an adjusting mechanism which makes it possible to adjust the spacing of the holding element 32 to the hanging element 38.

Preferably, this adjusting mechanism is constructed in two stages. On the one hand, the length can be set in predefined stages via a locking element 50. On the other hand, in a second stage, a fine adjustment is possible, which takes place via an adjusting nut 52.

In the present embodiment, the adjusting element 36 is tubular and receives the element 31, preferably a bar-shaped element 54, on one end of which the holding element 32 is attached. The rod-shaped element 54 can be displaced in the tubular locking element 50 in the longitudinal direction. In the rod-shaped element 54 are preferably provided perpendicular to the longitudinal axis of the element 54 holes, which are indicated in Fig. 2 by the reference numeral 58 and can be seen as black dots. These holes 58 define the predetermined positions of the first stage of the adjustment. The locking element 50 is designed so that it can be plugged through a corresponding opening in the adjusting element 36 and corresponding holes in the element 54 in order to achieve a locking of the two elements.

Instead of a bore, a slot 56 is provided in the adjusting element 36, so that the locking element 50 is displaceable in the inserted state within the slot.

With the help of the adjusting nut 52, the locking element 50 can now be brought within the slot in the desired position, so that a fine adjustment is possible.

In Fig. 4, the charge-holding device 30 is shown again more clearly, in particular, the two mutually parallel rods 40, 42 and the hooking element 38 are clearly visible.

In Fig. 5 an alternative embodiment of the adjusting element 36 is shown and designated by the reference numeral 36 '. The difference to the above-described adjusting element is that the hooking element 38 is not fixed but hingedly connected to the adjusting element 36 '. The suspension element 38 can be rotated about an axis S2 which is perpendicular to the longitudinal axis of the element 54, to some extent. The possible range of rotation can be seen in the upper illustration in FIG. 5 as a dashed outline of the element 54.

This articulated connection allows the parallel alignment with the payload, for example, to the thresholds of a switch, even if the payload was stored twisted at a certain angle in the loading plane. This may be necessary depending on the shape of the payload in order to maintain the permissible carriage loading profile. Furthermore, irrespective of the orientation of the adjusting element, a continuous transmission of force to the charge holding device on the carriage is achieved.
