SU18662A1 - Restraining (depreciation) device for the elimination of blows upon the entry of ships - Google Patents

Description

In the proposed device designed for protection (of an exclusive gate from a ship strike, a chain of enveloping blocks fastened at the ends of revolving levers in the plane of the side walls of the sluice, which are located one on each side of the sluice), is applied across the canal, while the ends of this chain are balanced by weights. In addition, additional chains are attached to these levers, thrown over the system of fixed blocks and one movable block with a load hanging on it that regulates the tension of the chains, which have their other ends attached Attached to the exit gate panel. This achieves an automatic, coordinated with the closing and opening of the exit gate, raising and lowering from the bottom of the lock a transversely stretched chain, designed to brake and delay the ship.

In the schematic drawing of FIG. 1 shows a longitudinal section of the airlock; FIG. 2 - its top view; FIG. 3-longitudinal section of the gateway with a modified device; FIG. 4 is a top view of this device.

Perpendicular to the axis of the gateway, chain D is located, slung over the blocks a n e, mounted on the ends of the levers P (Fig. 1 and 2), which are located one on each side of the gateway. Chain D ends with weights D intended to create equal weights, tension the chain and balance the weight of the levers P with all the details on them.

To drive 7a of the chain C to the proper operating position corresponding to the existing level and lowering it to the bottom of the sluice, the point t of the lever P is connected to the point n of the panel of the door at. additional chain c, thrown through the system of fixed blocks d and one movable block to the regulatory load o. The points of attachment of the additional chain with on the levers P and on the gate are chosen in such a way that when the gate is closed, the lever P occupies the highest position, and when the gate opens, the lowest.

With such a device, raising and lowering the chain C is associated with the rotation of the door leaf.

The modified device provides instead of one chain D two or more vertical chains interconnected and interconnected to work with chains D. These chains pass through a group of blocks a and h and are attached to weights T with the help of mobile, counterbalancing tension of these chains, blocks.

This achieves the ability to make the chains thinner, reduce the diameter of the blocks, and most importantly, when the vessel is piled, the entire brake load will not be applied at one point, but will be distributed to several points, which gives a greater guarantee of the safety and intactness of the vessel.

In a modified device, when it is installed in front of the lower gate of the sluice from the upstream, automatic operation is achieved by using floats with proper lifting force attached to the levers I, or the floats may be completely absent if the buoyancy of the levers is sufficient for this purpose. In this case, no additional chains are required, and due to floats or lever buoyancy, the chain C rises to its upper (working) position when water rises in the chamber and descends when water is lowered.

In order to facilitate the movement of the levers P along the side walls of the airlock, the end of the lever and its middle are provided with rollers rolling along guide rails fixed in the side walls. The narrow end of the rail J7-o6pa3Horo may be clogged during operation, and since cleaning its lower END is difficult, (7-shaped rails are replaced by ordinary ones, for which links are placed in the link D, located at the ends of the arms P and in the body of the block, than the tension of the chain C is eliminated by weights Γ, and the convergence of the ends of the long arms of the arms P. caused by this tension

When lifted, the lever P stops at the appropriate level, with the help of the hinged fingers H, turned in, depending on the change in the level of the water in the airlock. Additional chain, raise the lever P, bring it to the finger H and keeps it in this position until the gate is closed.

In order to reduce the length of the arms P, the proposed device has been modified in this way (Figs. 3 and 4) that the mechanisms for raising and lowering the chain obstacle C are located in the gateway part between the chain C and the exit gate. In addition, it

The modified device provides for the location of the levers P in the recesses of the cabinet part, which is achieved by protecting them from the vessel’s collapse when the latter leaves the lock. The elimination of the immersion of goods G in water is achieved by the fact that the blocks a are replaced by a system of blocks b and block g (Fig. 3) located at the end of the short lever P.

The subject of the patent.

1. A holding (depreciation) device for eliminating impacts when locking vessels, characterized by the use of a chain C stretched across the gateway, covering blocks of arms P and thrown over the ends with weights G through blocks in on the axes of rotation of arms P, or through blocks in the ends of the short arms of these levers and additional chains c, thrown through a system of fixed blocks d and movable, with a regulating load o, block k, attached at one end to the cloth of the exit gate, and the other to the lever P for the purposes of automatic wound with closing and opening of the exit gate, raising from the bottom of the lock to the desired height and re-lowering the chain C.

2.Video change of the device described in paragraph 1, characterized in that instead of one chain D two or a row are placed under each other located chains connected by vertical chains passing through the corresponding groups of blocks a and b and attached to the goods G using movable, balancing the tension of these chains, blocks — for the purposes of greater safety of the vessel with its shaft on the chain obstacle D.

3. Modification of the device described in paragraphs 1 and 2, when installed before the sluice gate leading to the lower bay, is used for the purpose of automatically raising and lowering the chain obstacle D. instead of additional chains with floats of proper lifting force fastened to levers P, or just the levers P, designed with sufficient buoyancy.

4. When characterized in and. Claims 1-3; Apparatus for facilitating the movement of the arms P along the side walls of the sluice, rolling along the guide rails of the rollers fastened in the side walls to the rollers fastened with the arms P.

5. When described in pp. 1-3 fixture application, for stopping the levers with a chain barrier at the appropriate level, of the folding fingers of H.

6. When described in pp. 1-3 of the application of a check, placed in the chain link and the body of the block, to eliminate the chain C caused by the tension by weights P to bring the ends of the long arms of the arms P. closer together.

7. Change as described in p. 1-3 devices, characterized in that in order to reduce the length of the arms P and protect them from being hit by the ship, the mechanisms for raising and lowering the chain barrier Ts are located in the part of the gateway between obstacle Ts and the exit gates, and the levers P are placed in the recesses of the cabinet part so that the panels of the open gate they are protected from contact with the exiting vessel.
