Description

Pontoon lifting lock The invention relates to a pontoon lifting lock with one in its raised position at the height and connection position of the transfer platform carriageway, Sliding or the like. Mechanically lockable pontoon.

There are already pontoon lifting locks are known where im Pontoon firmly embedded guide tubes from the ground; Vein lock protruding from the top Include columns, with their in their upper part by reducing the diameter formed shoulders in slots of the guide tubes sliding locking rails then be able to work together if this is dependent on the ascending pontoon step in the area of the shoulders. The locking position of the pontoon with the Columns correspond to the height and connection position to the track connection of the transfer platform, Helling or the like. Facilities of this type require even with heavily dimensioned columns high-pressure-resistant materials in order to be proportionate to the ones given to intercept the pontoon Small circular ring areas of the column shoulders absorb the loads that occur to be able to. But even if the given, especially with smaller boats Should suffice shoulder surfaces, the locking and support device is due the easy solvability and vulnerability of the parts to be machined with great precision not reliable enough for a robust, carefree operation. These shortcomings have a more sensitive and heavier effect, especially when moving in and out Ships out.

According to the invention, these disadvantages are avoided -that Supporting parts attached to the flanks of the pontoon with pillars or the like of the side walls the lock cooperate in such a way that @ aß the supporting parts below the top layer of the pontoon laterally outside the area of these pillars or are in guiding engagement with these, in or above the upper stroke position of the pontoon, however, get perpendicularly over the pillars, so that the pontoon means its supporting parts after draining water from the sluice or letting in water in the pontoon sits on these pillars in the lifting position.

The advantages achieved by the device according to the invention exist that the mechanical equipment required for a hoist is based on the The simplest basis has been brought about that the work process is absolutely safe and secure the simplest imaginable and that with this pontoon + lifting lock opposite the hitherto known hoists the lowest material and cost expenditure has been achieved is.

In the drawing, an embodiment is shown, namely Fig. I shows a longitudinal section of the lift lock with the raised position Pontoon, Fig. 2 the longitudinal section according to Fig. I with the pontoon lowered, Fig. 3 a Floor plan of the lift lock, Fig. 4, guided through the middle of the lift lock Cross-section with the pontoon lowered in a raised position.

A floating pontoon b is housed in the lock room a (Fig. I to 4). The loads to be expected are on the inner longitudinal side walls of the lock room as well as the static and other technical requirements accordingly strong trained support pillars c attached or built. These support pillars can be used as fixed if necessary, also removable vertical supports or as from the Swivel supports that can be swiveled out from the wall or other supports that can be moved sideways be trained.

For lowering the pontoon b onto the supporting pillars c of the lock walls is the floating pontoon on its outer side walls with attached or built-in support parts d, the dimensions of which are adapted to the gaps between the pillars c are.

The lift lock works as follows: Should an incoming Ship. z. B. od a submarine. Like., Lifted out of the water and on a horizontal The floating pontoon is in its lowest position. Then, after the water level has been equalized, the sluice gate f is opened and the ship drives into the lock over the pontoon. The lock gate is closed again. By pumping out the swimming pool. the pontoon rises with the ship to the intended draft of the pontoon out of the water. Meanwhile the water level was in the lifting lock by the required height, with the maximum load up to about Iocm, lifted under the sole of the transfer table, so that the lower edge the supporting parts d on the side walls of the pontoon high enough above the upper edge the pillar c is on the side walls of the lift lock. Unless as vertical Supports fixed piers c and No swivel supports from the wall or other lateral supports Slidable supports are built in, the pontoon is on the usual machine Travel with the ship now by the pillar width c to the front edge of the transfer table g pulled and locked with this so that it is only in the vertical direction can move.

In this highest swimming position, the pontoon is either lowered the water level in the sluice lowered or evenly by opening slides flooded and thus sits on the side support pillars c, so that a rigid and stable roadway to the adjoining transfer table is made.

Should a ship be brought into the water from the horizontal slipway, so the pontoon rests initially in the separated state on the support pillars c and forms a rigid and stable roadway that is locked at the head end. The submarine or The ship is transported on the trolley from the slipway via the transfer platform to the Pontoon b driven. The lock on the head side is released. With upscale The water level in the lifting lock rises pontoon b by pumping out the floating tank from the supporting pillars c and is made mechanically, provided solid vertical supports the wall and no laterally movable supports are built in to support the Pillar width c withdrawn so that it can sink freely next to the support pillars c can. Now it is lowered to the lowest level by evenly flooding it, so that the ship floats.

In the meantime the water level in the lift lock a. until Water level compensation lowered in the known way. The lock gate is opened and the submarine or ship can exit the pontoon lift lock.

If the pontoon b is to be lowered without loading, the floating box becomes of the pontoon b is filled with water by opening the slide and thereby lowered. Electrical blockages and float arrangements in the pontoon's floating box b ensure that there is a sudden sagging or diving out or one-sided Diving in and out of the pontoon and thus corners in the guides do not occur can.

The pontoon b has one both in length and width swimming box divided into several compartments, which eats so that it eats the weight of the respective ships to be transported including their own weight of the pontoon by buoyancy, fully compensated.

P ATE NTANSPRf'CHE: i. Pontoon lifting lock with one in its raised position in: Height of a sliding cockpit: ahn, slipway or the like that can be connected to this; Pontoon, characterized in that on the flanks of the pontoon (b) attached support parts (d) with pillars or the like. (c) the side walls of the lock (a) cooperate in such a way that the supporting parts below the uppermost layer of the pontoon or the position at the level of the transfer platform are laterally outside the area of these pillars or in guiding engagement with them, in or above the upper hoof position of the pontoon (b), however, reach vertically over the pillars, so that the pontoon can be placed on these pillars by means of its supporting parts by draining water from the lock or letting water into the pontoon. 2. pontoon helicopter according to claim I, characterized in that the pillars (c) designed as a fixed vertical extension of the side walls of the lock (a) are and that the pontoon (b) after reaching its uppermost end position by itself known means with the production of the direct connection to the transfer table (Slipway) drawn to this around the width of the pillar and locked in this position will. 3. pontoon lift lock according to claim I, characterized in that on stalls the pillar swivel supports or side-sliding supports can be used.
