Description

The invention relates to a trolley, can be overcome with the sails on ships. Dolly vehicles are used, for example, on naval ships for the transport of materials.

From the DE 10 2013 003 432 B3 For example, a trolley is known which has an elongated load-receiving body and four rad leg modules attached thereto. Each Radbeinmodul has four star-shaped arms arranged over wheels. Two of the four Radbeinmodule are arranged in front and form a front Radbeinmodul pair. The remaining two Radbeinmodule are arranged at the rear and form a rear Radbeinmodul pair. The front and rear camber modules each include a height adjustment gear to maintain the load receiving body at a same height when overcoming a slurry.

From the EP 2 210 793 A2 is another trolley known, which consists of a first car part with a first load-receiving body and a second car part with a second load-receiving body. The first carriage part is connected via a hinge connection with the second carriage part. To overcome a Sülle folds the first and the second carriage part successively up and back, the cargo is moved from one to the other load-carrying body.

The invention is based on the DE 10 2013 003 432 B3 the task is to create a trolley that can easily overcome sinking and maneuver easily in narrow aisles.

This object is achieved by a trolley with the features of claim 1.

The advantages of the invention are that the trolley is easy to handle and is very flexible and can be moved in all directions. This allows the trolley to maneuver well even in narrow aisles, without the trolley needs to be pushed back and forth in a curve. As a result, even longer transport routes can be covered quickly and safely.

The trolley has an elongate load-carrying body and at least 5 Radbein modules attached thereto. Many wheel leg modules ensure good load distribution and stability. This allows high loads.

The single rad leg module includes a bottom side horizontal beam having a first end and a second end and a leg portion having a first end and a second end such that the leg portion is centrally located on the horizontal beam with its first end. As a result, the shape of the Radbeinmoduls is defined in principle. The free ends that define a triangle are assigned certain functions.

Thus, a first wheel is disposed at the first end of the horizontal carrier and a second wheel at the second end of the horizontal carrier. This two wheel per Radbeinmodul arrangement gives a stable ride. Only with large obstacles it comes to a desired buckling.

Furthermore, the leg part is articulated at its second end to the load-receiving body via a pivot bearing, such that the rad leg module can exert pivotal movements in both directions of rotation starting from a driving position towards obstacle folding positions. In an obstacle folding position, the wheels are lifted off the ground. For example, even if the wheels of two adjacent Radbeinmodulen are lifted, the trolley moves safely and stably thanks to its other Radbeinmodule whose wheels are supported on the ground.

The pivoting movement of the Radbeinmoduls toward one of the obstacle Einklappstellungen takes place against the force of a preloaded spring. The force of the preloaded spring stabilizes the driving position. Further, the force of the preloaded spring causes the Radbeinmodul can automatically fold back from one of the obstacle Einklappstellungen in the driving position. Therefore, no drive for the pivoting movement of the Radbeinmoduls necessary.

The leg part has a compression and rebound device, which is provided with a damper. Here, the compression and rebound device acts in relation to the driving position in a vertical direction. Without the compression and rebound device, the wheel facing the obstacle would raise the load-bearing body too much at the beginning of the pivotal movement. Thanks to the rebound and rebound, the load-bearing body maintains its height during the pivoting movement to overcome obstacles.

The first and the second wheel are each supported in a wheel receptacle which is rotatable about a vertical axis. This allows the wheels to align freely in any direction, providing high maneuverability.

According to one embodiment of the invention, the rad leg modules are so on Load receiving body arranged that seen in the longitudinal direction two laterally arranged Radbeinmodule alternate with a single, centrally located Radbeinmodul. This causes a camber module to swing into an obstacle retracted position without colliding with a longitudinally adjacent camber module. As a result, many Radbeinmodule can be arranged closely behind one another, whereby a good load distribution is made possible.

The pivotal movement of the Radbeinmoduls towards one of the obstacle Einklappstellungen takes place, as stated above, against the force of a preloaded spring. According to a related, cost-effective embodiment, two prestressed springs each engage the leg part and clamping points on the load-receiving body, wherein the clamping points on the load-receiving body relative to the longitudinal axis of the leg part in the driving position are mirror images of each other.

According to a further embodiment of the invention, the first wheel and the second wheel on a rubber tires. This ensures a vibration-free transport.

According to a further embodiment of the invention, the first wheel and the second wheel are provided with an obstacle protection. This prevents tilting with the obstacle and causes a jerk-free pivoting movement up to one of the Obsteinseinappappstellungen.

According to a further embodiment of the invention, the load-receiving body is divided into a lower part and a load-carrying upper part displaceable thereon in the longitudinal direction. With the shifting of the load-carrying upper part, the center of gravity shifts. Thus, the center of gravity can be adjusted in an obstacle crossing with respect to the supporting Radbeinmodule, which additionally increases the stability.

Embodiments of the invention are explained below with reference to the drawings. Showing:

1a a trolley, with the Süllen can be overcome on ships, in perspective view;

1b the in 1a shown dolly, in side view;

1c the in 1a shown dolly, in front view;

2a a Radbeinmodul of in 1a shown trolley, in perspective view;

2 B this in 2a shown Radbeinmodul, in side view;

3 a structure of a Radbeinmoduls, as a schematic diagram.

The 1a . 1b and 1c show in different views a dolly 1 , which can be used to overcome sinking on ships. The dolly 1 initially has an elongate load-carrying body 10 on. On the load-carrying body are eight Radbeinmodule 20 attached. To overcome a puddle, the Radbeinmodule can 20 give away and fold back.

As 1a and 1b best show are the Radbeinmodule 20 such on the load-receiving body 10 arranged, that with respect to the longitudinal direction two laterally arranged Radbeinmodule 20 with a single, centrally located Radbeinmodul 20 alternate. As a result, many Radbeinmodule can be arranged closely behind one another, without colliding during pivoting with an adjacent, not pivoted Radbeinmodul.

The 2a and 2 B show in different views the single Radbeinmodul 20 ,

The functioning gives the 3 again. The Radbeinmodul 20 comprises a bottom-side horizontal support 30 with a first end 31 and a second end 32 and a leg part 40 with a first end 41 and a second end 42 , such that the leg part 40 with his first end 41 centered on the horizontal beam 30 is arranged. As a result, in principle, the shape of the Radbeinmoduls 20 Are defined. The free ends that define a triangle are assigned certain functions. So is the first end 31 of the horizontal carrier 30 a first bike 33 and at the second end 32 of the horizontal carrier 30 is a second bike 36 arranged. This two wheel per Radbeinmodul arrangement gives a stable ride. Only with large obstacles it comes to a desired buckling.

Furthermore, the leg part 40 at its second end 42 on the load-carrying body 10 over a pivot bearing 43 hinged. The Radbeinmodul 20 can exercise pivotal movements in both directions, starting from a driving position F towards obstacle Einklappstellungen H. In an obstacle folding position H, the wheels are lifted off the ground. Even if the wheels of a Radbeinmoduls 20 or the wheels of two adjacent cradle modules 20 are lifted, the trolley drives 1 thanks to his other wheel leg modules 20 safe and stable.

The pivoting movement of the Radbeinmoduls 20 towards one of the Hemmeinseinklappstellungen H takes place, generally speaking, against the force of a preloaded spring. Described in more detail, two biased springs grip 51 and 53 each on the leg part 40 and clamping points 52 and 54 on the load-carrying body 10 at, with the clamping points 52 and 54 on the load-carrying body 10 relative to the longitudinal axis of the leg part 40 lie in the driving position F mirror images of each other. The feathers 51 and 53 stabilize the driving position F and fold the Radbeinmodul automatically back from one of the obstacle retracting H in the driving position F. Therefore, no drive for the pivoting movement of the Radbeinmoduls 20 necessary.

The leg part 40 has a compression and rebound device 45 on, which is provided with a damper and which acts relative to the driving position F in a vertical direction. Without the compression and rebound device, the wheel facing the obstacle would raise the load-bearing body too much at the beginning of the pivotal movement. Thanks to the rebound and rebound mechanism 45 retains the load-carrying body 10 during the pivoting movement to overcome obstacles height.

The first bike 33 and the second wheel 36 are each in a wheel 34 respectively. 37 held, which is rotatable about a vertical axis. This will allow the wheels 33 and 36 align freely in any direction, thereby achieving high maneuverability. The wheel pictures 34 respectively. 37 could additionally be provided with a spring-damper unit, especially if rigid wheels are used.

The first bike 33 and the second wheel 36 have a rubber tire. A rubber tire dampens and springs equally.

The procedure for crossing a slurry S is as follows: preceded by the transport carriage moving to the left. The wheel 33 bumps against the hull S. As the transport cart moves on, the wheel leg module pivots 20 to the right into the obstacle folding position H. The remaining, not pivoted Radbeinmodule 20 are sufficient to ensure that the load is transported safely on the trolley. Has the rad leg module 20 overcome the slurry S, it works to the left in the driving position F back.

The first bike 33 and the second wheel 36 may additionally be provided with an obstacle protection.

Likewise, the load-carrying body could 10 be divided into a lower part and a longitudinally displaceable thereto load-carrying upper part to adjust the center of gravity in an obstacle crossing can.
