Abstract

A chain, wherein the extent of bending of the chain is stably restricted by a simple structure and wherein fixed members are automatically locked and unlocked.  A chain formed by connecting plate members to each other is provided with a slackening conveying device having drive sprockets and interlocked sprockets which are arranged at intervals determined so that the intervals between conveying pins of the chain are reduced, and the slackening conveying applies slack to the tension of the chain at corners of the chain.  The plate members each have a connecting pin and a slit into which the connecting pin is slidably inserted.  Each slit comprises a large width section and a small width section.  The plate members are fixed to each other when the connecting pins slide in the longitudinal direction of the slits and fit in the small width sections.  When the tension between the plate members is slackened by the slackening conveying device to cause the connecting pins to slide in the opposite longitudinal direction and fit in the large width sections, the fixation between the plate members is removed to allow the plate members to bend freely.

Description

Chain and chain transport device

The present invention relates to a chain and a chain transport device used for sling and horizontal transport for lifting a transported object.

Chains are used in applications such as slings for lifting conveyed objects and horizontal conveyance.

However, the conventional chain has a problem in that when the conveyed object is lifted, the chain is kinked and the conveyed object rotates and becomes entangled, so that a safe operation cannot be performed.

Therefore, for example, Patent Document 1 below proposes a kinking prevention tool for a sling cord that prevents kinking by providing a spacer between two sling cords that lift a heavy object vertically and fixing the sling interval. Yes.

However, in the method described in Patent Document 1, since the sling interval cannot be made very wide, the problem is that the two sling cords rotate together to cause kinking and the heavy object rotates. was there.

Patent Document 2 below proposes a sling that can regulate the degree of chain bending to a predetermined amount or less by providing a plurality of block bodies on the upper surface of the chain sling.
However, the sling described in Patent Document 2 has a complicated structure including a plurality of block bodies on the upper surface of the chain sling, and since the cross section of the block body is rectangular, the corner of the block body is bent when the sling is bent. Since the blocks are in contact with each other, the wear of the block body is severe, and the degree of bending of the chain cannot be stably regulated.

In order to solve the above problems, the inventor is a rope in which a plurality of outer layer members are connected as described in Patent Document 3 below, and has a polygonal or circular hollow shape in a cross section of the outer layer member. An inner layer member and a slide shaft member are disposed in the hollow portion, and the outer layer member and / or the inner layer member are constituted by a frame made of a hard material and a net attached to the frame, and the inner layer member Has a structure in which a plurality of hard members are connected and fixed to the slide shaft member, and is slidable in the longitudinal direction of the outer layer member, and a connecting portion between the hard members and a connecting portion between the outer layer members are provided. A rope has been proposed which, while being freely bent when matched, is not bent more than a certain range when the connecting portion between the hard members and the connecting portion between the outer layer members are shifted.

However, the rope described in Patent Document 3 is difficult to apply to the sling that lifts the conveyed product because it is necessary to manually perform the operation of shifting the connecting portion between the hard members and the connecting portion between the outer layer members. There was a problem.
