Abstract

The utility model provides an element gripping device for replacing a lifting appliance of a remote-control crane in a hot chamber. The device comprises a mechanical lifting appliance (1), a lifting hook (2) and a steel wire rope sleeve (6), wherein the lifting hook (2) is hung on the mechanical lifting appliance (1); the steel wire rope sleeve (6) is hung on the lifting hook (2); and the lower end of the steel wire rope sleeve (6) is fastened on an element (5). Shown by results, the element gripping device provided by the utility model is capable of replacing primary and secondary electric lifting appliances of the remote-control crane to complete the lifting of the element and meet the production requirement. The element gripping device has the advantages of simple structure, convenience in operation, low failure rate and cost and the like.

Description

In a kind of hot cell, substitute the element grabbing device of remote control crane suspender

Technical field

The utility model belongs to small-sized spentnuclear fuel post-processing technology field, is specifically related to substitute in a kind of hot cell the element grabbing device of remote control crane suspender.

Background technology

In the element disintegration process of some spent fuel element post-processing, need in disintegration hot cell, adopt the major and minor electric lifting tool of remote control crane to realize respectively the crawl of the upper and lower termination of element.The situation that there will be one of major and minor electric lifting tool or whole faults in the hoisting process of element, now needs the artificial dismounting of suspender to clean decontamination to hot cell, and maintenance cycle is longer, affects manufacturing schedule.Therefore, in order to guarantee the continuous operation of process system, need a kind of substitute technology of research badly, the normal lifting of element is disintegrated when realizing electric lifting tool fault.The electric lifting tool of fault can row maintenance again after system orderly shutdown.

Summary of the invention

The purpose of this utility model is the defect that overcomes prior art, solves when the major and minor electric lifting tool of hot indoor remote control crane was when lifting spent fuel element lost efficacy, and a kind of easy device of alternative electric lifting tool is provided.

The technical solution of the utility model is, substitutes the element grabbing device of remote control crane suspender in a kind of hot cell, comprises mechanical suspender, suspension hook and steel wire loop, and mechanical suspender is hung suspension hook, and suspension hook is hung steel wire loop, and steel wire loop lower end is fastened on element.

Described steel wire loop comprises lifting rope sling and fastening rope sling from top to bottom successively, and the upper end of lifting rope sling is for being connected with suspension hook, and lower end connects fastening rope sling, and fastening rope is locked and lies in top or the bottom of element.

Described hoisting rope puts and is provided with dead ring.

Described fastening rope puts friction sleeve is set.

The beneficial effects of the utility model are: by using this device, element is lifted, result shows to substitute the lifting that the major and minor electric lifting tool of remote control crane completes element, meets production requirement.That this element grabbing device has is simple in structure, easy to operate, fault rate and low cost and other advantages.

Accompanying drawing explanation

Fig. 1 is former element grabbing device structural representation.

Fig. 2 is element grabbing device schematic diagram.

When Fig. 3 gets element for hanging, steel wire loop is used schematic diagram.

Fig. 4 is the a-quadrant partial schematic diagram of Fig. 3.

Fig. 5 is the B region partial schematic diagram of Fig. 3.

In figure, 1, mechanical suspender; 2, suspension hook; 3, electric coupler; 4, electric lifting tool; 5, element; 6 steel wire loops, 7-lifts rope sling, the fastening rope sling of 8-, 10-friction sleeve, 11-dead ring.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

Former element grabbing device structure, as shown in 1, comprises the mechanical suspender 1, suspension hook 2, electric coupler 3, the electric lifting tool 4 that connect successively, and after electric coupler 3 energisings, electric lifting tool 4 gripping elements 5, realize the function that lifts spent fuel element.

The technical solution of the utility model is, in a kind of hot cell, substitute the element grabbing device of remote control crane suspender, as shown in Figure 1, comprise mechanical suspender 1, suspension hook 2 and steel wire loop 6, electric coupler 3 and electric lifting tool 4 on former element grabbing device do not re-use, but because dismounting is complicated, can dismantle; Machinery suspender 1 is hung suspension hook 2, and suspension hook 2 is hung steel wire loop 6, and steel wire loop 6 lower ends are fastened on element 5.

Steel wire loop 6 comprises lifting rope sling 7 and fastening rope sling 8 from top to bottom successively, and the upper end of lifting rope sling 7 is for being connected with suspension hook 2, and lower end connects fastening rope sling 8, and fastening rope sling 8 tightly lies in top or the bottom of element 5; When lifting rope sling 7 upwards hangs tight solid rope sling 8, by the self-tightening effect of rope sling, fastening rope sling 8 is fastened with top or the bottom of element 5, realizes it is captured to function; When with manipulator control lifting rope sling 7, fastening rope sling 8 being nested into behind the top of element, the mechanical suspender 1 that hoists, fastening rope sling 8 is fastened the top of element 5, as shown in Figure 3; Along with the hoisting of mechanical suspender 1, element 5 is promoted to and shears hot cell again, keep flat on steel linear; Then with manipulator, decline, make tightly to tie up to the element 5 fastening rope slings 8 in top and unclamp, and be displaced downwardly to the bottom appointed part of element 5, recurrence rises mechanical suspender 1, fastening rope sling 8 is fastened the bottom of element 5, then along with the hoisting of mechanical suspender 1, element 5 is promoted in disintegrating machine.On lifting rope sling 7, be provided with dead ring 11, for fastening with suspension hook 2.On fastening rope sling 8, friction sleeve 10 is set, for increasing the friction force that hangs rope sling while getting element 5.

Above embodiment of the present utility model is explained in detail, above-mentioned embodiment is only optimum embodiment of the present utility model, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make various variations.
