Description

Lifting / lowering device, loading system and related method

Technical area

The present invention relates to the technical field of loading liquid media, in particular liquid Verladegut, for example of gasoline fuels or diesel fuels.

State of the art

The loading of loading material into transport kettles, in particular into rail-bound boiler or bulk goods wagons, usually takes place via a downpipe connected to a joint scissor device, in particular via a telescopic tube with an outer travel tube. This arise in the downpipe associated with resting Domkonus by lowering the

Transporting vessel movements in the system, whereby the lowering of the transporting vessel is conditioned, inter alia, by the increasing degree of loading, that is to say by the growing filling state of the transporting vessel.

Presentation of the present invention: object, solution, advantages

Based on the disadvantages and inadequacies set out above, and in appreciation of the state of the art outlined above, the present invention is based on the object, when resting on the storage and / or transport case downpipe, especially in resting on the dome of the storage and / or transport device Domkonus the downpipe to be able to bring about an independent compensation or an independent compensation for resulting from the sinking of the storage and / or transport device movements in the electric drive system. This object is achieved by a lifting / lowering device or lever device with the features specified in claim 1 and by a method having the features specified in claim 9. Advantageous Ausges- and expedient developments of the present invention are characterized in the respective subclaims.

The present invention is based on the principle that in case of resting on the storage and / or transport case downpipe, especially in resting on the dome of the storage and / or transport device Domkonus of the downpipe, caused by lowering of the storage and / or transport device movements in System be compensated by at least one freely movable Verladearm independently or compensated.

The lifting / lowering device or lever device according to the invention and the method according to the invention are provided, for example, for the connection to a downpipe of a so-called TOP SPOT system.

A significant advantage of the present invention is that when loading the aforementioned media, for example gasoline fuel and / or diesel fuel, in a standing on a scale tank car, a constant value is created on the balance, which can be compensated by taring. The inventive lever mechanism for independent tracking of the system ensures that only borrowed the (weight) force or the (weight) pressure of Verladearms rests on the dome of the tank car.

Another essential advantage of the present invention is that the billing based on the mass or the weight of the loaded medium, for example the loaded gasoline and / or diesel fuel, eliminating the effect of the varying contact force or the varying Bearing pressure of Domkonus can be done on the transport tank. The present invention further relates to a system for loading liquid loading material, in particular gasoline fuel and / or diesel fuel, in at least one storage and / or transport device, in particular in at least one transport tank at least one, for

Example railbound, boiler or bulk material wagon, comprising at least one, in particular connected to at least one articulated scissor device, downpipe.

This system has at least one freely movable Verladearm with preferably a plurality of tubes which are movably connected to each other via swivel joints.

The loading arm is associated with the downpipe for filling the tank, which is for example part of a railway car, wherein the downpipe as

Telescope tube may be formed with at least one outer tube and at least one inner tube. The outer tube can be displaceably mounted axially displaceably on the inner tube and displaceable by means of at least one adjusting device.

Finally, the present invention relates to the use of at least one lifting / lowering device according to the kind set out above and / or at least one system according to the kind set out above and / or a method according to the above-mentioned type when loading liquid loading material, in particular gasoline fuel and / or diesel fuel, in at least one storage and / or transport device, in particular in at least one, for example, rail-bound, boiler or bulk material wagon.

Best way to carry out the present invention

FIGS. 1A to 1C show an exemplary embodiment of a system 100 arranged above a tank car 200 to be filled, in the form of a loading installation for loading of loading material, namely liquid media (gasoline and diesel fuels).

The loading system has a joint scissor device

- with a joint scissors for horizontal movement and

- with a joint scissor for vertical movement.

A telescopic tube 40 (compare FIGS

Fig. 3C) connected to the outside traversing. The telescopic tube 40 is a system that can be moved by a tube-in-tube construction by means of electric screw jacks. The guides are made by means of bushes, for example made of polytetrafluoroethylene (= PTFE, trade name: Teflon), with appropriate guide ratios.

The bottom of the telescopic tube 40 is centrally fixed via a tube, at the end of the running nut of the screw jack ensures the movement. The (weight) force with which the mandrel cone assigned to the telescopic tube 40 presses on the transporting vessel 200 depends inter alia on the degree of loading, that is to say on the filling state of the transporting vessel 200.

For this reason, arising in the dome of the transport vessel 200 Domkonus the downpipe 40 resulting from the sinking of the tank car movements in the electric drive system by at least one freely movable Verladearm automatically compensated or compensated.

While the drives for the pivoting movements are performed without self-locking, the axis C (see Fig. 2) is designed for safety reasons with self-locking. The axis C remains in each approached position, even if the brake is open on the engine.

The attachment of the lifting cylinder H (see Fig. 2) on the axis C via a movable suspension A, whereby the lifting cylinder H is completely relieved when placing. The suspension A is queried via preferably three proximity initiators S1, S2, S3, so that the discharge of the lifting cylinder H is maintained by a drop in the tank car.

By means of the proximity initiators S1, S2, S3, the following positions P1, P2, P3 are interrogated:

P1: first position of the suspension A, with which the loading arm is lifted;

P2: second position in which the lifting cylinder H is relieved; From this point, it is possible, for example, to continue driving defined via the rotary encoder;

P3: third position of the maximum relief of the lifting cylinder H. Until the damping of this proximity switch, the lifting cylinder H can be driven. If this is no longer damped, but a loading continues to be carried out, a decrease in the Verladearms can take place up to the position P2. Then it is tracked again to position P3. This takes place until the loading process is completed. The lifting cylinder H then extends and the proximity initiator in position P1 is steamed. The normal travel position has been reached.

Advantageously, all drives are equipped with limit switches / proximity switches S1, S2, S3. Optionally, an approximation initiator can be arranged in each case such that damping takes place via at least one flag on the rotary joint.

In addition, the drives are equipped with (in each case) at least one absolute rotary encoder in order to signal the exact position to the controller at any time.

For the respective movement of the first axis A of the three-axis control and the second axis B of the three-axis control, the speed is about ten degrees per second; the third axis C of the three-axis control moves at a speed of about six degrees per second.
