Description

Gate lock for ship lifts. For gate locks on ship lifts have always had strong fluctuations in the water level of the upstream and downstream water - '. iche Difficulties caused. You have seen the fluctuations in the water level so far compensated by the fact that, as in Fig. z of the drawing in longitudinal section and. in Fig. 2 in cross section -, - y is illustrated schematically, the seal on Trough t by means of the shield attached to this: 2 placed further down and a correspondingly large counter-shield (position shield) 4 is attached to section 3 Has.

This auxiliary device has the following disadvantages: The area of the posture sign, against which the trough sealing rubber lies, must be processed very precisely and to protect of the rubber are covered with cladding sheets. Furthermore, the trough becomes r when it is at open trough gate 5 and maintenance gate 6 (both in the locked position in Fig. r shown) is coupled to the line 3, by a strong water pressure of pulled the trigger. This pressure must therefore by a correspondingly large counterforce to be overcome. Creating such a strong back pressure is special if the sealing shield 2 is still extended downwards, difficult to carry out. The exact production of the shields covered with cladding sheets is difficult and expensive. It has now been proposed to record when the water level changes significantly To cope with the fluctuations in water, put a chamber lock in front of the elevator's position. This is probably Jii way out, but a very expensive one. The operation a ship lift with pre-locks is unfavorable. The attitude of the same i1i # i, -eii \\ a: standing in the pre-lock is #difficult and should (1-_irch a special Pvlinl) iverl: take place.

According to the invention, the disadvantages mentioned above should pass through a double version of the maintenance gate lx should be removed, and that should be Gate consist of an upper and a lower part. The top part of the gate is at the bottom Part of this is attached to the posture in different directions in the direction of the wing. The lower Part of the maintenance gate is fixed during the lock operation and only then becomes moves when it matters, we - :; release fluctuations in the water level (los balance. Smaller fluctuations can @hirch aniorcinung a short. Trog-, ii-: litungsschilles To be taken into account. Since this movement of the attitude gate through e one side Pressure (going on water is made difficult, you can remove this pressure in a short time Separation from (lein posture gate also slidable in the 1-I.ülienriclitung Attach the auxiliary gate and then the Rauni between your lower posture gate and the Fill Ililfstor finitely water.

Inn Ahli.3 of the drawing is an exemplary embodiment of the invention in a vertical longitudinal section through the door lock on the underwater of a Schiitsliebewerks illustrated.

The trough i is on. your illustrated. Exit end finitely provided with a short seal c: child 2 and a gate 5 that can be moved in the height direction. In the exit position of the trough, the sealing shield 2 rests against the lower part 7 (loose on the post 3 in the H). The upper part 6 is also different in the direction of height at the lower part.> L: ar. In Abh.3 the upper part 6 (los holding gates un l da: trough gate 5. In alligehol: ener position; illustrated. On the trough side of the holding gate, according to the illustrated example, an auxiliary gate 8 can be moved in the vertical direction at a few distance from the gate arranged. the space 9 between your Haltungstor and your Hilfstor 8 is connected to the. channel or watercourse Ti 'through a line io, which can be closed by means of slide ii. another lockable slider 12 by line 13 leads from the space 9 by the pump sump 1q located under the ship's trough. The mode of operation of this gate lock is as follows: With normal or slightly fluctuating water level, the lower part 7 of the maintenance gate (Ab :). 3) is fixed. In the case of locks, only the trough gate 5 and the upper part 6 of the maintenance gate are moved. The sealing shield 2 is able to take into account slight fluctuations in the water level. If there are larger fluctuations, the lower part? of the attitude gate in attitude 3. This shift is expediently independent of the lock operation.

Uni the one-sided water pressure on the lower part; of the attitude gate to eliminate and thereby facilitate its movement, can (read auxiliary gate 8 gehol: en and by opening the valve i r by means of the line io water in the room 9 be left. If the lower part 7 of the maintenance gate is nicely adjusted, it closes one the slide i i and opens the Schiel-er 1a. The water then runs out from 9 14, whereupon (read auxiliary gate 8 ”leather is lowered.

This gate lock can. for both upstream and downstream water Find use. The movement device of the gates 6, 7 and 8 is arbitrary.
