Abstract

The invention relates to a folding and stretching device for particular ship ramps, which consist of articulated sections and be operated by Seilzuege. To reduce the effort a folding and stretching device is to be created, which consists essentially of already provided on the ramp for other purposes functional elements. According to the invention, the ship facing the section of the ramp has a herausklappbares from the roadway and pivotable about the hinge axis between the sections surface part, which is connected by hydraulic cylinders with the aeuszeren ramp section and the free end formed by the Betetigungsseilen the ramp Seilzuege with the inner ramp section is.

Title of the invention

Palt and stretching device for ramps

Field of application of the invention

The invention relates to a FaIt- and stretching device for folded in a vertical stowage ramps, especially for ships

Characteristic of the known technical solutions

Folding and stretching devices for sections composed of folding around a hinge axis ramps are known in various designs. They comprise either cantilevers formed by extending the side members of a ramp section beyond the axis of the joint and cables with their own drive arranged between them and the other ramps (eg DD-AP 87991) or from both in the region of the joint axis Sections attacking lever systems that are actuated by hydraulic cylinders (eg DD-AP 133693) · All these solutions have in common that for the FaIt- and stretching process special attachments (cantilevers, Habe! System) with corresponding Antriebsele elements are required, the an increased effort

Object of the invention .

The object of the invention is to reduce the expense of folding and stretching a ramp.

Dar le gum κ of the essence of the invention

The object of the invention is to provide a FaIt- and stretching device with extensive use of existing from articulated sections and means of winches driven by winches operated ramp already for other purposes existing components and drive elements »

The achievement of this object provides that the inner, the ship facing section of the ramp releasably locked with it, herausklappbares from the road surface and pivotable about the hinge axis between the two sections surface part, with the outer section by adjusting an angle between connected to the Fahrbahnebenen both sections hydraulic cylinder and its remote from the hinge axis end with the inner section by further formed from the ropes of the existing cables for operating the cables further cables is connected «

An advantageous embodiment of the invention is that the cables for operating the ramp and the formed between the fold-out surface element and the inner section of a single continuous rope.

The invention will be explained in more detail using an exemplary embodiment. In the accompanying drawing show:

Fig. 1j is a plan view of the ramp in operating position

The hinged to a ship 1 ramp consists in a known manner of an inner section 2 and an outer section 3 which are pivotally connected to each other about a hinge axis 4. The ramp is suspended by cables operating on the inner section 3 and serving to actuate the cables, and those arranged on the ship 1,

• not shown winches are driven. The inner section 2 has a hinged about the hinge axis 4, from the road plane fold-out surface part 5t which is locked in the folded state by Verriegele ~ e in directions 6 with the inner section 5 »The surface part 5 is connected to the outer section 2 by a for Setting an inclination angle between the lanes of the sections 2 and 3 provided hydraulic cylinder 7 connected. Between inner section 2 and applied by the hinge axis 4 end of the surface part 5 are cables 8; 8 ¹ arranged, which are formed from the over pulleys 9 »9 'from the cables 4 and 4 * here continued ropes. In the exemplary embodiment, the cables 8; 4 and 4 ^f ; 8 * of a single rope passing through in that order, the ends of which lead to the driving winches. This ensures that working at unequal. Winches a rope compensation between the cables can be done on both sides of the ramp, so that a torsional stress of the ramp parts is avoided. However, with sufficiently synchronous winches, the cooperating cables 8; 4 and 8 ¹ ; 4 'consist of separate ropes.

In the operating position of the ramp, the surface part 5 is folded into the plane of the inner section 2 and locked with this. With the winches driven by the winches 4; 4 * the ramp is brought into a vertical position, so that their inner section 2 abuts provided on the ship 1 abutments and can be fixed with locks, also not shown, After loosening the locks 6 of the surface part 5 is by unwinding the ropes of the drive winches the outer section 3 pivoted about the hinge axis 4 down. To initiate the pivoting operation of the outer section 3 , the outer section 5 is expediently angled away from the inner section 2 so far with the hydraulic cylinder 7 that the line of action of its center of gravity lies outside the joint axis 4

 If the folded ramp is to be moved from the stowage position into the

are brought to the operating position, the surface part 5 is first pivoted to the hydraulic cylinder 7 it »such a position that the acting on the surface part 5 cables 8; 8 · can cause a sufficient torque about the hinge axis 4, so that by winding the ropes on the winches, the outer section 3 about the hinge axis 4- can be pivoted upward until the surface part 5 collapses into the road plane of the inner section 2. After locking the surface part 5 with the inner section 2 and releasing the locks of the inner section 2 on the ship 1, the ramp is now lowered by unwinding the ropes from the winches in the operating position «

The invention FaIt- and stretching device consists essentially of the ramp already provided for other functions components and requires no additional attachments and drive units, whereby the effort compared to the known solutions is significantly lower »
