Abstract
The utility model relates to a special hoisting tool for a nuclear waste bucket, which comprises a hoisting frame, a cross beam which is connected with the hoisting frame, a hook claw which can move on the cross beam, a self-locking mechanism which is positioned between the hoisting frame and the cross beam and a lubricating mechanism of a moving part, wherein the hoisting frame is composed of two connecting rods which are hinged into a Y shape and a trolley; the other end of each of the two connecting rods is hinged on the trolley; road wheels of the trolley are arranged between an upper and a lower level tracks of the cross beam; the hook claw is hinged on the trolley. The hoisting tool can open and close the hook claw by means of self gravity and lifting force. While the utility model hoists the nuclear waste bucket, the hoisting tool firstly goes down, the self-locking mechanism is released until the hoisting tool touches the upper edge of the nuclear waste bucket, the hoisting tool moves up, and the connecting rods of the hoisting frame retract inward under the action of the lifting force, thus the trolley on the cross beam moves inwards and the hook claw tightly clamps and hoists the waste bucket.
Description
Technical field
The utility model belongs to hoisting appliance, specifically a kind of nuclear waste barrel special hanger.
Background technology
Top cover is arranged at the top of nuclear waste container, and periphery is provided with the lifting groove, during the lifting nuclear waste container is to allow hook extend into the lifting groove of container from both sides, so must use special hanger.Present nuclear waste barrel special hanger adopts the electric screw open-and-close mechanism to drive hook mostly, and controls the opening and closing state of hook, the electronic lubricated fuel loading system of the lubricated employing of each movable parts by self-locking mechanism.This suspender not only structure is huge, complicated, and has brought difficulty to the operation of system under the nuclear environment.For now, the maximum hoisting weight of the nuclear waste container special hanger that uses only is 5 tons now, also do not see the report that relevant large-tonnage nuke rubbish holds special-purpose device suspender, the lifting problem that how to solve the large-tonnage nuclear waste container also is one of current problem that needs research.
Summary of the invention
The purpose of this utility model provides a kind of nuclear waste barrel special hanger that relies on suspender self gravitation and lifting hoisting force can make the hook opening and closing.
The technical solution that realizes above-mentioned purpose is: the nuclear waste barrel special hanger that is provided comprise suspension bracket, with suspension bracket bonded assembly crossbeam, can be at hook mobile on this crossbeam, self-locking mechanism between suspension bracket and crossbeam and the lubricating structure of movable parts.Special feature of the present utility model is: said suspension bracket is made up of two connecting rods that are hinged to " people " font and dolly, and the other end of said two connecting rods is hinged on the dolly; The road wheel of said dolly places between the upper and lower horizontal rail of aforementioned crossbeam, and said hook is hinged on the dolly.Unsettled and when not working by hoist cable when this suspender, self-locking mechanism guarantees that hook is in and opens station.During lifting, suspender is descending, run into the upper edge of nuclear waste barrel after, self-locking mechanism discharges; Suspender is up then, and under the effect of hoisting force, the suspension bracket connecting rod inwardly bounces back, and then the dolly on the crossbeam is moved to the inside, and hook clamps and promote trash receptacle.Self-locking mechanism can lock the dolly stroke in setting stroke, thereby the side direction gripping power of pawl to trash receptacle angled in restriction.
Compared with prior art, of the present utility model simple in structure, need not use electric device or other engine installation, the opening and closing of hook are to finish voluntarily in the process of lifting, so simple to operate, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the lubrication system of each rotating axis component among Fig. 1.
Fig. 3 is the cross-section structure of Fig. 1 center member.
The specific embodiment
As shown in Figure 1: suspension bracket 1 is made up of 11,12 and two dollies 13,14 of two connecting rods, and hoist cable parts 2 are connected in the hinged place of connecting rod 11,12; The body of dolly 13,14 is a spider, and two jiaos of its lower end are equipped with road wheel 13a, 13b respectively, and its upper end is hinged with the other end of connecting rod.Road wheel 13a, the 13b of dolly places between the last horizontal rail 31 and lower horizontal track 32 of crossbeam 3, and hook 4 is hinged on the outer end of dolly body.One end of self-locking mechanism 5 links to each other with connecting rod 14, and the guide positioning plate 51 of self-locking mechanism is fixed on the crossbeam 3, and this a part of structure is same as the prior art.In order to keep suspension bracket balance and stable, also hinged auxiliary connecting rod 6 constitutes a parallel-crank mechanism between connecting rod 11 and crossbeam 3.As previously mentioned, suspender is to keep descending under the open state at hook, after running into the top cover upper edge of nuclear waste barrel, self-locking mechanism 5 discharges, and suspender is up then, under the effect of hoisting force, two connecting rods 11,12 of suspension bracket 1 inwardly bounce back, drive dolly 13,14 and move to the inside, hook 4 stretches in the lifting groove of nuclear waste barrel, and then clamps and promote trash receptacle.After trash receptacle is transported to assigned address and lands, loosen hoist cable, self-locking mechanism 5 discharges, and outwards opens at the effect lower link 11,12 of suspender from gravity, forces dolly 13,14 outside motions and loosens trash receptacle.
As shown in Figure 2: the movable parts lubricating structure of present embodiment is made up of with the lubricating cup 74 that is built in this axle sleeve 72 the double helix guide groove 73 that is located on fortune parts axle sleeve 72 inner hole surface, the lower end of lubricating cup 74 communicates with aforesaid double helix guide groove 73, and numbering 71 is the rotating shaft in the axle sleeve 72 among the figure.Adopt this lubricating structure not only further to simplify the structure, simple to operate, and have self-lubricating function, and prevent the corrosion of movable parts, guarantee suspender work safe against all possibilities under nuclear environment.
Fig. 3 has provided the structure of present embodiment employing deep beam, is respectively equipped with the tool steel backing plate 33,34 through Quenching Treatment on horizontal rail 31 on the crossbeam 3 and lower horizontal track 32, in order to improve the ability to bear of orbital plane to contact stress.The hanger structure material that adopts this composite structure to solve the large-tonnage nuclear waste container had both required good welding performance, requirement can be born the technical difficulty of tens of tons of contact stress again, is the lifting needs of 20 tons nuclear waste container thereby satisfied maximum weight.
