SU19068A1 - Fixture for placing the core chains in valuable drawers - Google Patents

Description

On most ships, chain boxes for the core ropes are positioned with their longitudinal axis across the vessel, and the bridle for the chain is on the edge of the box, close to the center plane of the vessel, which makes it difficult for the core to work, because the chain lays all the time in one corner. a box that does not fill the whole area of it, and you have to stretch the chain through the box manually, at the risk of falling under the sinking rope In order to facilitate the work on the arrangement of the core chain, in the proposed arrangement for placing the core chains in the chain drawers, a hinged reinforced inclined chute is used, equipped with a counterweight and a fork at the upper end under the junction box, in which one chain link is strengthened and the rest of the chain is influenced by by its own weight, it rolls down the tray and, after filling it with the weight of the counterweight, outweighs it, overturns it and falls to the bottom of the box; in order to prevent the counterbalance from tilting in the opposite direction, the latter is supported by pins; in the form of execution, the fork can be made detachable from the tray, as well as detachable.

In FIG. 1 is a front view of the device; FIG. 2 is the same, top view; FIG. 3-cross section of the tray. To the wall of the chain box, which has a cable cutter, is hingedly mounted in an inclined position on the brackets 3, tray 1 with counterweight 2 and fork 4 located at the upper end of it, coming under the cutter. In order to prevent the counterweight from tilting in the opposite direction, there are pins 5 in the wall of the crate below. When the core is turned on, one of the chain links is inserted into fork 4 and, since the next link cannot pass through it, the chain is stalled, i.e. its rectilinear downward movement ceases, and the following chain links, getting slack, are loaded into the tray and, as a result of a bias, crawl down the tray.

Crawling to the box wall, the chain in the tray will have a slightly larger weight than the counterweight 2 of tray 1, as a result of which the tray overturns along with the fork, and the chain falls into the box along its length, and at the same time the chain link flies out of fork 4. After that with a fork under the influence of the counterweight returns to its original position.

Another link is inserted into fork 4, and the chain loading process continues.

For convenience, fork 4 can be made separate from the tray and the rope, pad, pull the link from the fork. When etching the core so that the chain does not break the fork with a fork, it is necessary to tilt the tray into the crate wall, for which a small recess can be made in the wall. Fork 4 can also be detachable for convenience, i.e. strengthen one wall on the hinges and take to the side.

The subject of the patent.

1. A device for placing the crust chains in chain boxes, characterized by the use of tray 1, hinged in an inclined position on the brackets 3, equipped with a counterweight 2 and fork 4 at the end of it, which is under the cutter, in order to strengthen one fork in the fork for one so that the rest of the chain, under the influence of its own weight, rolls down the tray and overturns it when the weight of the counterweight is outweighed.

2. Application of the pin 5 in the device described in paragraph 1, which prevents the counterweight from tilting in the opposite direction.

3. The form of the fork described in paragraph 1, characterized in that this latter is made detachable from the tray as well as detachable.
