Description

[Detailed description of the invention] This invention mainly relates to a hanging device for hoisting heavy objects such as stones using a hoisting machine.

For example, when lifting stones with a hoisting machine, a certain chain with a hook at the tip is generally used, and this chain is suspended around the stone, and the middle part of the chain is hooked onto the hook. Furthermore, the free end of the chain is locked to a hook of a hoisting machine attached to a beam, etc., and in this state, the hoisting machine is hoisted to remove any slack in the chain hanging from the stone. While tightening the tension, the stone is being lifted up.

By the way, in the chain with a hook, even if the middle part of the chain is hooked on the hook, only the single link that makes up the chain cannot be hooked on the hook. The chain slides very poorly, so sometimes it is impossible to reliably tighten the slack in the chain suspended from the stone, and the stone is lifted, and during the lifting, the stone becomes loose in the chain. There were accidents such as falling off.

The present invention was devised in view of the above problems, and is a hanging device that can extremely easily tighten the slack in a chain hanging from a heavy object such as stone, and can safely lift said heavy object. This is what we are trying to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The hanging device according to the present invention will be explained below according to the embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a hanging tool main body formed with a support part 3 for a chain 2 on one side, and the width dimension P1 of this main body 1 is set to be greater than or equal to a plurality of links (3 links) of the chain 2, in other words, the above-mentioned The length is longer than the vertical interval between the plurality of links, and the insertion groove 4 of the chain 2 is provided in the width direction of the main body 1 on the other side of the hanging tool main body 1, so that the chain 2 is connected to the hooking part of the chain 2. ing.

The insertion groove 4 has one side opened outward in the width direction of the main body 1, and the groove width P2 on the opening side of the insertion groove 4 is set to the lateral interval R1 of the links 21 as a diagonal line. is larger than one side S of the virtual square and smaller than the lateral spacing R1 of the links 21, and
By making the groove width P2 on the groove bottom 41 side of the insertion groove 4 slightly larger than the lateral spacing R1 of the links 21, the chain 2 can slide smoothly in the insertion groove 4, and can also be ejected. This prevents the chain 2 from being accidentally removed from the insertion groove 4.

Furthermore, the groove bottoms 41 at both lengthwise ends of the insertion groove 4 are expanded outward from the main body 1 so that the chain 2 can slide more smoothly within the insertion groove 4.

Next, the support part 3 of the chain is formed with grooves 31 having a spacing slightly larger than the material diameter R2 of the link 21, and the link 21 of the chain 2 is inserted into the groove 31, and the support part The chain 2 is supported on the main body 1 by passing a headed pin 5 through the space between the chain 3 and the C-link 6 at the insertion end of the pin 5.

Note that C in the figure indicates stone.

The hanging device of the present invention, which has the above-mentioned structure, is mainly used when hoisting stone C with hoisting machine A, and is used in the following manner.

First, hang the chain 2 around the outer peripheral wall of the stone C, and
A plurality of links 21, 21, in the middle of the chain 2
... are inserted into the insertion groove 4 while being inclined with respect to the groove width direction of the insertion groove 4.

After that, the free end of the chain 2 is attached to the hook B of the hoisting machine A.
By locking the chain 2 and performing the hoisting operation of the hoisting machine A, the slack in the chain 2 suspended from the stone C is squeezed out through the insertion groove 4, and the stone C is strongly tightened by the chain 2. Then, the stone C is lifted up.

As explained above, the width of the main body of the hanging device is greater than or equal to the plurality of links of the chain, and the insertion groove through which the plurality of links of the chain can be inserted is provided in the width direction of the main body. Even if the chain comes into strong pressure contact with the bottom of the insertion groove when tightening, the pressure force is distributed to each of the links inserted into the insertion groove, so that the chain moves smoothly in the insertion groove. Moreover, since both lengthwise ends of the insertion groove are expanded outward, there is no risk of the chain getting caught in the corners at both ends of the insertion groove. As a whole, the chain can be securely tightened against the stone, and therefore lifting heavy objects such as stones can be carried out extremely safely compared to conventional chains with hooks.
