Abstract
In a chain sheave/chain-rope system wherein an end of a chain is connected to an end of a rope via a splice member, guide members are provided on the splice member for cooperation with guide members within a hawsehole that precedes the chain sheave. As a result of this cooperation, the splice member and the chain attached thereto are brought into the correct position for engagement prior to their entry onto the chain sheave.
Claims5
An assembly on a chain sheave/chain-rope system wherein an end of a chain is connected to an end of a rope in a splice member adapted to travel over a chain sheave with opposing sheave flanges by lying within a recess or pocket of the sheave formed by chain engaging studs, the splice member comprising a sleeve socket for receiving the rope end and a half-link of chain, from which the end link of the chain is suspended, characterized by guide members on the splice member which cooperate with guide members in a hawsehole preceding the chain sheave, by means of which the end link of the chain is brought into the correct postion for engagement prior to entering the chain sheave, the splice member having four protruding pins spaced 90.degree. apart around the sleeve socket, two diametrically opposed pins being disposed in the same plane as the half-link of chain, the assembly being so constructed that during passage of the splice member about a chain sheave, one pair of diametrically opposed pins will ride on the sheave flanges whereas one pin of the other pair of pins passes into the groove between studs of the chain sheave, the sleeve socket thus lying within a pocket of the chain sheave, the pins in one of the pairs being longer than the pins in the other pair and the longer pins acting as said guide members.
An assembly on a chain sheave/chain-rope system wherein an end of a chain is connected to an end of a rope in a splice member adapted to travel over a chain sheave by lying within a recess or pocket of the sheave, the splice member comprising a sleeve socket for receiving the rope end and a half-link of chain, from which the end link of the chain is suspended, characterized by guide members on the splice member which cooperate with guide members in a hawsehole preceding the chain sheave, by means of which the end link of the chain is brought into the correct position for engagement prior to entering the chain sheave, the guide member being arranged within the hawsehole for cooperation with guide members disposed on the splice member, such that the end link of the chain, which hangs from the chain half-link disposed on the splice member, is brought into the correct position for engagement prior to the chain's entry onto the chain sheave, said guide members being in the form of two diametrically opposed grooves extending along the interior walls of the hawsehole in the direction of cable passage, with guide ramps leading up to the respective guide grooves.
