Abstract

The invention relates to control houses on inland vessels, which are lowered at bridge crossings to the level of the deckhouse. It is the object of the invention, in the lowered state of the wheelhouse to allow the helmsman on the side of the deckhouse over the view on the back part of the waterway. The object is to make the lowering-stroke device kinematically so that when lowering and lifting the wheelhouse at the same time a querschiffs directed movement takes place. According to the invention, the object is achieved by arranging the stubs of the lowering-stroke device operating according to the known principle of the scissors, such that the one pair of parallel stanchions is rotatable and immovable on the deck and the wheelhouse and the other pair of parallel stanchions are rotatably and slidably mounted on the deck and the wheelhouse with the ends.

a. Title of the invention

Lowerable wheelhouse, especially for inland vessels with low fixed point height.

b. Field of application of the invention

The invention relates to wheelhouse on inland vessels, which are lowered at bridge passages to the level of the deckhouse.

c. Characteristic of the known technical solutions

Due to the need for maneuvering ships overview over the waterway is required for the arrangement of the wheelhouse depending on the length of the ship a minimum height above the water level.

To secure the bridge passage in inland vessels, a fixed point height is specified, which determines the maximum height above the water level.

In order to fulfill these conditions, barges are used on inland vessels whose height varies over the water level.

The known designs have the disadvantage that in the lowered state, the view from the wheelhouse is locked behind by the deckhouse behind it, whereby the security is limited in: control of the vehicle. In addition, it is from Na teiX that the lowering-lifting system and the control of the ship he required transmission elements such as cables, ropes and chains take up a place that goes beyond the space located between the wheelhouse and ship's deck.

d. Object of the invention

It is the object of the invention, in the lowered state of the control house the helmsman the view to the rear on the side of

Over deckhouse to allow without having to leave the wheelhouse. Another goal is to couple the required for committing the wheelhouse staircase with the lowering-stroke process of the wheelhouse and store it at the height of the deckhouse roof.

Explanation of the essence of the invention

In the currently known solutions, the movement of the wheelhouse when lowering and lifting is parallel to the midships level, so that it remains within the alignment line of the side walls of the deckhouse behind.

The task is to make the lowering-stroke device kinematically so that when lowering and lifting the wheelhouse at the same time a querschiffs directed movement takes place, so that the wheelhouse protrudes to a rear view required for the view on the side of the deckhouse.

According to the invention the object is achieved in that the supports of the known principle of the scissor lift lowering device are arranged such that the one pair of parallelliegender supports with the ends rotatably and immovably on the deck and the wheelhouse and the other pair parallelliegender Supports are rotatably mounted with the ends and slidably mounted in the transverse directions of the ship on the deck and the wheelhouse, it is advantageous to combine the inner pair of supports to a support element and form this for the accommodation of the transmission elements and as an emergency exit for the wheelhouse.

By said arrangement of the supports results in lowering and lifting the wheelhouse for the immovably mounted supports a rotational movement about their bases and thus for the head points a movement on a circular path, due to the connection with the wheelhouse and due to the kinematics of the slidably mounted supports is also given for all points of the wheelhouse.

Another inventive solution is that the required for committing the wheelhouse stairs at the upper end of the bracket, in which engages a mounted on the lower edge of the wheelhouse drive rod over which a locking piece is mounted.

When lifting the wheelhouse lying at the level of the deckhouse ladder is detected on the temples by zoom out on a circular path Mitnehmerstange, whereby the stairs brought into the upper end position and at the same time as a result of the transverse component of the movement on the circular path, the locking piece is pushed over the bracket.

Is at the initiation of Absenkvorganges the static friction between the deckhouse and ladder greater than the force acting at this point gravity of the ladder, the ladder remains in position until due to the movement on a circular arc the locking piece presses on the bracket, thereby overcoming the static friction and down the stairs is moved to the shelf in the area of the deckhouse roof.

embodiment

Reference to an embodiment, the invention will be explained in more detail.

The accompanying drawings show:

Figure 1: Front of the wheelhouse in top position Figure 2: Section A-A of FIG. 1st

Figure 3: top view, wheelhouse in the lowered state.

The wheelhouse 1 is supported by the pairs of parallel pillars 2 and 3, which are rotatably connected to each other about the same axis.

The pair of parallel pillars 2 are pivotally mounted at the lower ends in the bearings 4 on the deck and at the upper ends rotatably mounted in the bearings 5 on the wheelhouse.

The pair of parallelliegender supports 3 is slidably mounted at the lower ends in the mounted on deck guides 6 and at the upper ends rotatably mounted on the rails 7, which in turn are slidably supported in the rail bearings 8.

When lowering the wheelhouse 1, which is initiated by reducing the force on the tether. 1 ο, the support «pair 2 rotates about the bearings 4 on the deck, whereby the wheelhouse 1 übei the bearings 5 is lowered at the wheelhouse on a circular arc ,

234945 5

At the same time moves the pair of parallelliegender supports 3 with the lower ends in the guides 6 to the outside, which inevitably results in a horizontal movement between the wheelhouse 1 and the rails 7.

The lowering is completed by placing the wheelhouse on the stop pieces 9 on the deck.

When lifting the wheelhouse 1, which is initiated by tightening the tether 1o, e.g. by winds or working cylinder, the movements are carried out mutatis mutandis in the opposite direction until the stop of the running rail 7 to the boundary 12 below the wheelhouse.

The control elements 17 required for control and monitoring between the wheelhouse and machinery, are housed in the combined to form a support element pair of parallelliegender supports 2 such that the stress occurring by the lowering-stroke operation kept minimal v / ground.

When lowering the wheelhouse 1, the staircase 13 is inevitably moved downward over the bracket 14 located between the drive rod 15 and locking piece 14th

Before filing the staircase 13 on the roof of the deckhouse is displaced by the transverse component of the circular arc movement, the locking piece 16 from the area of action of the bracket 14 to the side and thus the wheelhouse 1 released for further downward movement along the front wall of the deckhouse.

When lifting the wheelhouse 1 is brought by inserting the drive rod 15 in the bracket 14 under relative rotation and displacement movement between these elements, the stairs 13 in their required to commit the wheelhouse position.
