Abstract

The utility model relates to a duplex type round link chain or a wire rope sling, in particular to a duplex type end ring or a hook type round link chain sling, which comprises an end ring, a hook. a round link chain, and so on. The end ring is composed of an inner ring and an outer ring which are formed by bending two round steels, the inner ring is embedded into the outer ring and the both rings are connected into a whole, so as to form a duplex type structure with the section presenting between a 8 shape or a long circle, and the shape of the duplex type structure can be a long circle, a circularity or a pear shape; the hook is formed by folding a round steel twice and then bending into the hook shapes which are connected into a whole, so as to form the duplex type structure with the section presenting between the 8 shape or the long circle, a circular hole is formed at the bending position for being connected with the round link chain, and the head of the hook is smoothly transited to ensure hooking to be convenient. When in use, the end ring (or the hook) of the duplex type structure is only required to be connected with the round link chain or a wire rope into a whole through welding a transition loop or a shackle. The end ring (or the hook) round link chain sling has the advantages that the force performance is good, the bearing capacity is high, the manufacturing cost is low, the manufacturing cycle is short, and the slings with various types can be manufactured according to the operating requirements.

Description

Compound end ring or hook type round-link chain Current Collector Sleave

Technical field

The utility model relates to a kind of Current Collector Sleave that is used for round-link chain, specifically a kind of compound end ring or hook type round-link chain Current Collector Sleave.

Background technology

In existing round-link chain Current Collector Sleave technology, during for large-scale crane or extra heavy, special suspended object, adopt the end ring of conventional structure or the round-link chain Current Collector Sleave that suspension hook is made then to be difficult to satisfy the handling requirement, mainly show as: 1. not only weight is big, cost is high, the manufacturing cycle is long for the end ring of forging conventional structure or suspension hook, and is difficult to be connected with round-link chain is supporting; 2. not only intensity is low for the end ring of weldering system conventional structure or suspension hook, and ruptures from welding junction easily.

Summary of the invention

The purpose of this utility model provides a kind of compound end ring or hook type round-link chain Current Collector Sleave, and it has the round-link chain or the wire rope sling tool of novel structure, dependable performance and low cost of manufacture, is particularly useful for the handling of large-scale crane or extra heavy and special suspended object.

Technical solution adopted in the utility model is: compound end ring or hook type round-link chain Current Collector Sleave comprise end ring or suspension hook, transition rings or shackle and round-link chain; End ring is made up of interior ring and outer shroud that two round steel respectively bend, and interior ring embeds outer shroud and connects as one, and forms the cross section in view of 8 words and oblong duplex, and its form has Long Circle, circle and pyriform; The hook-shaped that suspension hook is bent into after by a round steel two-fold connects as one, and forms the cross section in view of 8 words and oblong duplex, and its bending part is provided with circular hole, gib head place rounding off.

The beneficial effects of the utility model are: because auspicious ring and suspension hook all form the cross section in view of 8 words and oblong duplex, improve 75% than prismatic circular configuration intensity.The utility model has improved the stressing conditions of end ring (or suspension hook) from structure, have that stressed effect is good, load-carrying capacity is big, short being convenient to and the supporting advantage such as be connected of round-link chain of in light weight, low cost of manufacture and manufacturing cycle, and can make the Current Collector Sleave of various ways by operating needs.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Among Fig. 7: 1 compound end ring, 2 compound suspension hooks, 3 transition rings or shackle, 4 round-link chains.

Compound end ring mainly is divided into microscler, circle and pyriform by form, sees Fig. 1～Fig. 3; Mainly be divided into top ring (also claiming main ring), lower loop (also claiming suspension ring) and adapter ring (also claiming transition rings) by purposes, top ring is used for driving to be hung, and lower loop is used for suspended object to be hitched, and adapter ring is used for end ring or suspension hook is connected with round-link chain.Compound suspension hook is divided into wide oral hook and slot hook by mouth of hook size, mainly determines according to the suspended object suspension centre.The utility model is a kind of compound end ring or suspension hook for mainly hanging the round-link chain Current Collector Sleave of auxiliary, and can make multiple mode such as 1～4 limb by lifting requirements, and figure seven is one of the compound main ring of single limb, hook type round-link chain Current Collector Sleave.

This compound end ring or suspension hook are by being welded behind the low-carbon alloy round steel hot bending, and wherein, the interior ring of compound end ring and outer shroud interface also are provided with two-sided V-type welding cut and are arranged in the left-right symmetric middle part, and its form has Long Circle, circle and pyriform.Advantage such as the utlity model has that stressed good, the load-carrying capacity of compact conformation is big, low cost of manufacture and manufacturing cycle are short, and can make the Current Collector Sleave of various ways by operating needs.

Claims
