Description

Be used to promote the trip gear in cobalt 60 gamma irradiation sources

The utility model belongs to mechanical field, is meant a kind of trip gear that is used to promote cobalt 60 gamma irradiation sources especially.

At present field of food, modifying plastics and other a lot of aspect, utilize cobalt 60 as the existing history for many years of irradiation bomb, especially having been widely used aspect food fresh keeping, sterilization and the chemical industry.

In the irradiation production run, normally irradiation bomb cobalt 60 gamma sources are placed the source frame at present, the source frame moves up and down along guided way, and irradiation bomb cobalt 60 is stored in the bottom of well when flat; When the needs product irradiation, utilize the source frame to elevate the irradiation bomb cobalt 60 that places the well bottom from the well bottom, so that the product around it is carried out irradiation processing, after irradiation is finished, utilize the source frame irradiation bomb cobalt 60 to be put back into the bottom of well again.

Because irradiation bomb dosage is very big, safe operation is exactly primary requirement, therefore the irradiation bomb jacking system is provided with a series of safety interlocking mechanism, wherein accident forced landing mechanism is exactly important one, its requirement is: stop or when stuck when elevator system hinders for some reason, can there be a device that the source frame is put back to the shaft bottom, to guarantee safety.

At present in the irradiation production run, the structure that forced landing mechanism adopts usually is, quick coupling structure, this structure is with the fixing principle of steel ball, very heavy because of source frame and irradiation bomb weight, so worn steel ball is very fast, will change once general one or two years, as untimely replacing, major accident stuck or that the source frame comes off then can appear.

At above problem, the purpose of this utility model is, a kind of trip gear that is used to promote cobalt 60 gamma irradiation sources is provided, and it has simple in structure, easy to operate and safe and reliable advantage.

A kind of trip gear that is used to promote cobalt 60 gamma irradiation sources of the utility model, it is characterized in that, comprising having: a hanger, door-shape like, these hanger two ends are respectively chutes, affixed one tabular projection below in the middle of hanger has a hole on an end of hanger, this hanger is by a wire rope hanging support; One hook, this hook have a hook cross bar, link up with cross bar certainly and are extended with a hook pole to oblique below, at an end of hook pole one hook head are arranged, and this hook is linked up with on the tabular projection that spool is articulated on the hanger with one; One column, this column pass hole on the hanger and lean a end at the hook cross bar of hook; One weight has a slide opening in the centre of this weight, and this weight is by a wire rope hanging support; A pair of slide rail, this slide rail is fixed at two ends up and down; One source frame is framework, and the both sides of this source frame have runner block respectively, and this runner block cooperates with slide rail.

Wherein this slide rail is to be a wire rope.

Wherein this slide rail is to be arranged in parallel.

For further specifying structure of the present utility model and feature, below in conjunction with embodiment and accompanying drawing the utility model is made a detailed description, wherein:

Fig. 1 is a structural representation of the present utility model.

See also shown in Figure 1, a kind of trip gear that is used to promote cobalt 60 gamma irradiation sources of the utility model, comprising having:

One hanger 10, door-shape like, these hanger 10 two ends are respectively chutes 102, the slide rail of chatting after this chute 102 can supply passes through, affixed one tabular projection 101 below hanger 10 centres, have a hole 103 on an end of hanger 10, the weight of chatting after this hole 103 can supply 13 places, and this hanger 10 is by a wire rope 14 hanging supports;

One hook 11, this hook has a hook cross bar 112, be extended with a hook pole 113 from hook cross bar 112 to oblique below, end hook pole 113 has a hook head 114, on these hook 11 usefulness one hook axle 111 tabular projections 101 that are articulated on the hanger 10, there is a distance at the center of this hook head 114 with the center of hook axle 111, and this hook 11 is used for the source frame 16 chatted after the hanging support;

One column 12, this column 12 pass hole 103 on the hanger 10 and lean a end at the hook cross bar 112 of hook 11;

One weight 13 has a slide opening 131 in the centre of this weight 13, the slide rail of chatting after this slide opening 131 supplies 15 places, and this weight is by a wire rope 141 hanging supports;

A pair of slide rail 15, this slide rail is fixed at two ends about in the of 15, and this slide rail is to be a wire rope (but not as limit), and this slide rail 15 is to be arranged in parallel;

One source frame 16 is a framework, built-in irradiation bomb cobalt 60 (not shown), and the both sides of this source frame 16 have runner block 161 respectively, and this runner block cooperates with slide rail 15, and these source frame 16 hanging supports are on the hook head 114 of hook 11.

The course of work of the present utility model is:

One irradiation bomb well 3 is arranged below in radiation chamber 2, and the two ends of slide rail 15 (this slide rail 15 is a wire rope) that the utility model are used to promote the trip gear in cobalt 60 gamma irradiation sources are fixed on top in the radiation chamber 2 and the below in the irradiation bomb well 3.One lifting gear 1 (for prior art) is installed in the top, roof of radiation chamber 2, the hole that the wire rope 14 that this lifting gear 1 connects passes radiation chamber 2 tops is connected with hanger 10, and can drive the irradiation bomb upper and lower displacement, the hole that the wire rope 141 of this hanging support weight 13 passes radiation chamber 2 tops is articulated on the radiation chamber 2.During product in needing irradiation radiation chamber 2, start lifting gear 1 with irradiation bomb from proposing in the irradiation bomb well 3 to radiation chamber 2, so that product is carried out irradiation; After intact to product irradiation, restart lifting gear 1, irradiation bomb is put into irradiation bomb well 3.When irradiation bomb above irradiation bomb well 3, in the time of can not putting into irradiation bomb well 3 because of the fault of mechanical fault or lifting gear 1, then the wire rope 141 that is articulated on the radiation chamber 2 can be unclamped, this moment, weight 13 freely fell, and bump column 12, effect because of lever, the hook cross bar 112 of column 12 pushing tows hook 11 is to lower swing, and make hook 11 hook head 114 to opposite side, to top offset, and disengaging source frame 16, the source frame of making falls in the irradiation bomb well 3, thereby guarantees the safe in utilization of irradiation bomb.After fault is got rid of, only need hanger 10 is put into irradiation bomb well 3, can use the long handle instrument again with 16 hanging supports of source frame on hook head 114, and can carry out the irradiation operation again.

The utility model compared with prior art has: simple in structure, easy to operate and safe and reliable Advantage.
