Description

Title of the invention

Device for securing cargo in box-shaped transport containers

Field of application of the invention

The invention relates to a device for protecting the load, in particular of compact, rollable or non-rollable loading units, against unintentional displacement by acceleration forces within box-shaped transport vessels.

The load securing system is applicable to rail vehicles, in particular railroad mail cars and railway freight wagons, as well as to commercial vehicles, containers, cargo ships and aircraft.

Characteristic of the known technical solutions General cargo items in means of transport are secured against acceleration forces by pre-nailing of plowing blocks and / or by bracing with steel wire, chains or also with textile straps. Furthermore, it is known that remaining cavities are filled in holds with air bags to gently transport the load.

In US Pat. Nos. 3,433,179, 3,782,295, 3,799,070 and 4,079,677, load locks are described as crossbars that are journalled on perforated sidewall rails.

Ana dan US Patents 3606 842 and 3754 516 are known rhombenf örmige spreading mechanisms for the fixation of general cargo in land vehicles. In.den US Patents 3680 491, 3762 341, 3837 296, 4089 273 and 4222 696 and in the West German patents 2051 085 ₉ 2115 913, 2633 864, 2649 981, 2656 190 and 2752 635 and in the East German Patent 85 575 transverse wall segments are described, which are arranged between the transport units and locked in various ways.

From US-patent 3984 118 a system of U-shaped brackets for fixing pallets, in.Nutzkraftwagen.bekannt. German Federal Republic Patent Nos. 2,212,417, 2,111,336 and 2,340,315 describe, in particular in the floor, retractable clamping devices for the fixation of transport containers in land vehicles and aircraft.

Furthermore, in rail vehicles in the transverse direction diagonally tensioned locking chains are known.

Object of the invention

The aim of the invention is

to create an easy-to-use device for Transportschutζ for compact loading units;

- To allow by appropriate training and arrangement of the load securing the gentle transport of cargo units in rooms, with fixed Y / änder and also in the range of openable wall parts (side wall doors, sliding walls o, ä ");

- To provide a load securing that hardly restricts the clear load compartment dimensions of a transport vessel and is housed in light use so that loading work is not hindered and persons are not endangered;

- To provide a cargo securing, which is captively mounted on the transport vessel.

Explanation of the essence of the invention

The invention is based on the technical object of providing a universal fuse for the damage-free transponder.

port of loading units in vehicles, in particular railroad cars, and. in railway freight wagons, in order to avoid the laughing parts of known devices of this type.

The known devices have the disadvantages that items can not be so connected to your transport vessel to avoid loss completely, that they are a hindrance in the carriage of loose cargo, for example, when creating stacks of parcels, and that ea are mechanically complex constructions with great maintenance costs.

The simple means of destroying general cargo such as plow blocks, binding wires, - chains or textilgurte are associated with high cost of materials, because the funds themselves are mostly not reusable and können.weil damage to the transport vessel often caused by hail. The simple means cause high manual effort during use and are not always reliable.

The known diagonal tensioned chains to limit a cargo space can not be so tense depending on the type of closure that they limit the cargo exactly in place. However, this requirement must be raised many times to prevent damage to other cargo, or to ensure the puncture of equipment of the vehicles.

The stated object is achieved in that compact loading units are fixed with a Hubschranke in each hold. The invention is characterized by the following features

- The Hubschranke can move in the vertical direction and can be designed so that it limits the space at any desired height.

- dia vertical movement can be initiated at the barrier at any point.

- By dia peculiarity of the puncture, the Hubschranke can be used not only to limit the space with fast end walls, but also to secure light door openings and holds with larger openable wall surfaces.

- The Hubschranke can be designed so that loading units are gently protected against displacement.

According to the invention, the advantages are achieved by:

- a guide and roller arranged on both sides or a suitable sliding element (ζ · Β · pin, sliding shoe)}

- A mechanism for parallel guidance and mass balance for the Hub jank j

- a slight bend of the leadership »

The Hollen are mounted in the axial direction at both ends of the preferably consisting of a box tube barrier. The roller guide is realized by rail-shaped vertically arranged angle profiles. The mass balancing mechanism consists of two parallel eccentric cranks, a single shaft and one or more tension springs. The GIeichlaufweHe connects the pivot point © of the two cranks torsion-free, which synchronous movement is enforced.

At any point of the GIechlaufwelle one or more - preferably two - lever arms are attached. At the sides of the lever arms engages each a tension spring. In the interaction between tension springs and levers, a torque is generated at the continuous shaft, which compensates for the torque arising from the intrinsic masses of the barrier and the sliding crank components. In the upper position lever and line of action, the tension springs form an approximately right angle,. When the barrier is lowered, the concurrent movement will result

lever the tension springs increasingly strained. In accordance with the invention, the effective lever length is shortened at the same time. It is thus achieved that the torque does not increase to the same extent with increasing spring force in accordance with the spring characteristic. By adjusting the Sinflußgrößen spring stroke, Faderhärts, lever length, lever working angle and torque from the intrinsic masses of the barrier and the thrust crank parts ensures that the device has a balanced mass balance in all positions,

.Ausführungsbeispiel

The invention will be explained in more detail using an exemplary embodiment. The embodiment preferably relates to the application of the invention in the clear door space of a sidewall sliding door to a covered railway freight wagon of conventional design.

Show it:

Fig. 1: the isometric view of the Hubschranke, Pig. FIG. 2 is a sectional view taken along the line A - A in FIG

FIG. 1, FIG. 3. A plan of a covered railway freight wagon with compact loading units loaded longitudinally and transversely in the door space.

In Figure 1, the Hubschranke 1 is shown isometrically. The receiving pockets 10 are attached to the inner edges of the door pillars. In the receiving pocketη 10 is the Hubscnranke 1, at both ends of which are the rollers 11. Above the receiving pockets 10, the roller guides 9 are fixed to the inner edges of the door pillars. The push rods 2 are rigidly connected to the Hubscnranke 1. About the pin joints, the push rods 2 and the connecting rods 3 are coupled. The connecting rods 3 are rigidly fastened to the torsionally stiff synchronizing shaft 6. The GIelauflaufwelie 6 is rotatably mounted in the fixed point bearings 5, which are attached to the longitudinal upper chords of the freight car. Y / e he he are on the synchronizing shaft 6 two lever 7 rigidly attached. In the holes

at the ends of the lever 7, the tension springs are 8. eingehangen. Between the tension springs 8 and the fixed points 16 can be attached to a setting device ΊJ, Fig. 1, 2, for example, a commercially available turnbuckle can be used.

Dia use of the device according to the invention takes place in the illustrated example, Figure 3, as follows. After loading the two holds next to the doors, the transversely arranged lifting barriers 1 are brought into the lower end position. Subsequently, the load units are loaded in the door compartment transverse to the vehicle longitudinal axis and the Hubschranke closed at the door. Afterwards, the doors can be closed.

The device according to the invention ensures that the loading units can not tilt during transport, in particular in the case of impulses and transverse accelerations in routes, or that they can become jammed and jammed in one another or on the sliding doors. The application of the invention allows the full use of the door space as a cargo space, especially in cross-loading units.

* Due to the nature of the suspension of the stroke barrier 1, Fig. 2, and the roller guides 9 and the balanced mass balance, the device can be easily handled by an operator.
