Abstract
The invention discloses a submerged shearing device which comprises an upper supporting plate (1), a lower supporting plate (6), a supporting frame (4), a shearing rack (8), a motor (9), a transmission device (10), a worm (11), a camera device (3) and an illuminating device (5), wherein the upper supporting plate (1) and the lower supporting plate (6) are rigidly connected through the supporting frame (4) and supported on a lower base through supporting legs (13); a funnel (2) is arranged on the upper supporting plate (1) through a hole; a shearing rack (8) is arranged right below the funnel (2), the shearing rack (8) is fixed on the lower supporting plate (6), the shearing rack (8) is connected with a transmission device (10), and the transmission device (10) is connected with a motor (9); the lower supporting plate (6) is provided with a hole and a lower funnel (12). The invention has simple structure and small volume, and realizes the shearing operation of the components, especially the pipeline, under liquid.
Description
Technical field
The present invention relates to the nuclear reactor field of engineering technology, electronic shear under particularly a kind of reactor liquid.
Background technology
After reactor operation a period of time, some parts such as the fingerstall pipe of reactor core inside need to change.And the replacing of these parts need be at direct control under the liquid.Lack the replacing that special-purpose cutting implement is used for these parts in the present domestic reactor field.And the cutting implement that market is often seen, their volumes are bigger, be suitable for mostly operating on the ground, and this cutting implement are used to shear bigger parts relatively.Can't be suitable for for parts tiny in the reactor, can not satisfy the needs of reactor pit inside simultaneously.This cutting implement that is used for the reactor field does not still have report on open source literature at present.
Summary of the invention
The present invention has overcome deficiency of the prior art, provide a kind of simple in structure, volume is less, realize under the liquid the parts especially subsurface shearing device of pipeline shearing manipulation.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of subsurface shearing device, comprise upper backup pad, lower supporting plate, bracing frame, shearing stand, motor, gearing, worm screw, camera head, lighting device, upper backup pad and lower supporting plate are rigidly connected by bracing frame, are supported on the lower base by supporting leg; Funnel is installed in perforate on the upper backup pad; The shearing stand is set under the funnel, shears stand and be fixed on the lower supporting plate, shear stand and be connected with motor with gearing, gearing; Funnel is down installed in perforate on the lower supporting plate;
Handling for convenience, the present invention is all right: on the described upper support frame hanger is housed.Described camera head and lighting device are fixed on lower supporting plate or the upper backup pad by support.
Compared with prior art, the invention has the beneficial effects as follows: this device cooperates with shearing the simple of stand by funnel, can realize thin, little parts are sheared, and is simple in structure, by camera head, lighting device supervisory work, shearing manipulation good reliability.
Description of drawings
The structural representation of Fig. 1 device
1 upper backup pad, 2 funnels, 3 camera heads, 4 bracing frames, 5 lighting devices, 6 lower supporting plates, 7 hangers, 8 are sheared stands, 9 motors, 10 gearings, 11 worm screws, 12 times funnels, 13 supporting legs, 14 shear knives
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
The upper backup pad 1 and the lower supporting plate 6 of this device connect into rigid structure by bracing frame 4, and are supported on the lower base by supporting leg 13.Hanger 7 is housed on the upper backup pad 1, is used for the handling mobile device.Funnel 2 is installed in perforate on the upper backup pad 1, is provided with under the funnel 2 to shear stand 8, and funnel 2 imports the shear knife 14 of shearing stand 8 with the part that is sheared, and makes to be sheared part and to be placed on correct clipped position.Motor 9 under the liquid, gearing 10 are housed on the lower supporting plate 6, shear stand 8, motor 9 drives shear knife 14 motions of shearing in the stand 8 by the worm screw 11 of gearing 10, realizes shearing manipulation.
Perforate is equipped with down funnel 12 on the lower supporting plate 6, can remove by following funnel 12 after the shearing part finishes.Following funnel 12 can be provided with special-purpose reservoir vessel under it, the part that following funnel 12 will be sheared end slips into special-purpose reservoir vessel.
