Abstract
The utility model is a kind of No. 17 hitch overhead hoist, and overhead hoist comprises dedicated lifting hook, chain hoof ring, round pin, spring cotter and steel rope; Dedicated lifting hook is connected with steel rope by chain hoof ring, round pin, spring cotter; Round pin is fixedly connected with dedicated lifting hook, and chain hoof ring is connected with round pin and steel rope; Spring cotter is arranged on round pin one end and plays retaining effect.This practical information solves the technical matters of low, the poor stability of production efficiency, and proposing a kind ofly provides a kind of special overhead hoist for No. 17 hitches, simply lightly, convenient, flexible, is easy to operation.
Description
Technical field
The utility model relates to a kind of No. 17 hitch overhead hoist.
Background technology
No. 17 hitches are mainly used in company's extension of 70 tonnes of freight train, are installed on the two ends of car body.For many years, my intra-company, to the installation process of No. 17 hitches, adopts steel rope 1 to be directly wrapped on hook body 2 always, realizes, as Fig. 1 with overhead traveling crane handling steel rope.After installation, suspension hook falls by overhead traveling crane, unreeve, and steel rope is pulled down from No. 17 draw gears by operating personal more with it.The shortcoming of present operation process is as follows:
1) production efficiency is low.Before No. 17 hoisting through couplers, need wirerope-winding with it the hook.Hitch is placed on the ground, hook neck and ground space limited, wirerope-winding is inconvenient; After installation, also need steel rope to pull down from No. 17 draw gears with it, efficiency is lower.
2) poor stability.Hitch center of gravity is in gib head position, and in lifting process, gib head down, and hook tail upwarps, and very easily occurs steel rope obscission, brings very large danger to personal safety.
Utility model content
In order to solve, production efficiency in background technology is low, the technical matters of poor stability, and the utility model proposes a kind ofly provides a kind of special overhead hoist for No. 17 hitches, simply lightly, convenient, flexible, is easy to operation.
Technical solution of the present utility model is: a kind of No. 17 hitch overhead hoist, and its special character is: described overhead hoist comprises dedicated lifting hook, chain hoof ring, round pin, spring cotter and steel rope; Described dedicated lifting hook is connected with steel rope by chain hoof ring, round pin, spring cotter; Described round pin is fixedly connected with dedicated lifting hook, and chain hoof ring is connected with round pin and steel rope; Spring cotter is arranged on round pin one end and plays retaining effect.
Above-mentioned overhead hoist also comprises packing ring, and described packing ring is arranged between spring cotter and suspension hook.
Above-mentioned chain hoof ring lugless joining shackle, chain link end connects suspension ring.
Above-mentioned dedicated lifting hook adopts thickness 25mm, and the sheet fabrication of Q235 material forms.
Above-mentioned chain hoof ring gauge lattice are 16mm × 28mm × 70mm, chain link specification is 16mm × 64mm, suspension ring specification is 16mm × 100mm × 200mm, hair round pin specification is 20mm × 85mm × 79mm, packing ring specification is M30, spring cotter specification is 5mm × 20mm.The beneficial effect of the utility model No. 17 hitch Special-purpose hanger shipping units is as follows:
(1) production efficiency is high.Before decreasing No. 17 hoisting through couplers, by wirerope-winding at hook with it and after installation, by the process that steel rope is pulled down with it from No. 17 draw gears, and this device uses by space constraint, flexibly simple to operate.
(2) safety is high.No. 17 its dedicated lifting hooks of hitch Special-purpose hanger shipping unit are directly hooked in No. 17 draw gear body openings, should not break off relations, safe and convenient to use.

Fig. 1 is the structural representation of the utility model prior art;
Fig. 2 is the plan sketch of the utility model overhead hoist;
Wherein: 1-hangs tooth; 2-suspension hook; 3-round pin; 4-spring cotter; 5-chain hoof ring; 6-is a chain of; 7-suspension ring.
Detailed description of the invention
The utility model is for No. 17 hitch composition structures and assembling procedure feature, and provide a kind of overhead hoist of No. 17 hitches, this device should meet following requirement:
1) consider the feature of this operation, 70t level vehicle day maintenance amount increases gradually, and No. 17 hitches assembling quantity also increase thereupon, therefore this overhead hoist need be easy to link up with and pull down, light structure, be easy to use flexible.
2), during handling hitch, for ensureing that the relative position of allocation and transportation device and coupler body does not change, this device and coupler body need have enough location.
3) consider that hitch sole mass is comparatively large, shape is special, and center-of-gravity position is not easily determined, therefore overhead hoist need have suitable length.
4) according to production actual conditions, Q235 sheet material, round pin, spring cotter type of attachment is adopted.
No. 17 hitch sole masies are comparatively large, and coupler head is heavier, and afterbody is comparatively light, and center-of-gravity position is not easily determined.
As Fig. 2, a kind of overhead hoist, this device comprises dedicated lifting hook, chain hoof ring 5, round pin 3, packing ring, spring cotter 4 and steel rope.Steel rope and dedicated lifting hook are linked together by chain hoof ring 5, round pin 3, packing ring, spring cotter 4.Spring cotter 4 is arranged on round pin 3 one end and plays retaining effect; Packing ring is arranged between spring cotter 4 and suspension hook, and effect separates spring cotter 4 and suspension hook, reduces friction.
The feature of dedicated lifting hook is: adopt thickness 25mm, the sheet fabrication of Q235 material forms, and its shape matching is special, and one end is provided with axis hole, is linked together by round pin, packing ring, spring cotter with chain hoof annulate shaft hole.
Chain hoof ring gauge lattice are 16mm × 28mm × 70mm TB/T895-1999;
Chain link specification is 16mm × 64mm;
Suspension ring specification is 16mm × 100mm × 200mm;
Hair round pin specification is 20mm × 85mm × 79mm TB/T56-93;
Packing ring specification is M30;
Lock cotter pin specification is 5mm × 20mm;
The using method of this overhead hoist is:
[1] steel rope is hung on overhead traveling crane hook by overhead traveling crane cooperation, overhead hoist is hung No. 17 hitch places to be installed.
[2] be in after suitable height until overhead hoist, the suspension hook hook of overhead hoist is entered in the coupler body hole of No. 17 hitches.
[3] overhead traveling crane slowly lifts by crane, and inject in hook tongue apertures by the tooth that hangs of overhead hoist, overhead traveling crane lifts by crane.
[4] after treating that hitch installs, crown block hook falls, and is unloaded by the suspension hook of overhead hoist from the coupler body hole of No. 17 hitches.
