Abstract
The design's invention belongs to a kind of automatic releasing device, comprise three staggered form suspension hooks (1) and grab lift heavy thing, by the restraint release weight of unhook plate (10) to suspension hook (1), gland (2), axle (3), back of the body cap M30 × 1.5(4), dottle pin (5), dottle pin (6), fixed head (7), plug (8), back of the body cap M24(9), the support of breaking off relations of suspension ring axle (11), back of the body cap (12), hanging sleeve (13), suspension ring (14), hanging sleeve (15), axle (16) composition and rotational structure.Operate by experiment, ensure that the using function of product.
Description
Technical field
Patent of the present invention is a kind of mechanical part, particularly a kind of spent fuel storage rack fall-down test automatic releasing device.
Background technology
It is significant that autonomous Design meets CAP1400 weary storage screen work that is international and national legislation requirement.Because spent fuel storage rack is antidetonation I kind equipment, its design should meet holding structure integrality and execution security function ability under seismic (seismal effect.Require in standard examination outline annex: the main security function comprising the spentnuclear fuel pond of lining and screen work be various environmental load and abnormal load and irradiated fuel assembly drops or during regularly load and unload spentnuclear fuel the produced shock that drops of other weight effect under, make the shape that irradiated fuel assembly maintenance is safe.Because seismic response analysis relates to collision between storing fuel assembly and screen work storage chamber and Coupling effect of seepage rock deformation, fall to analyze to relate to and fall collision between fuel assembly and screen work and structure, material large deformation, calculating has strong nonlinearity, needs to be aided with verification experimental verification.By carrying out fall-down test to spent fuel storage rack testpieces, test figure can be provided for storage screen work assembly falls analysis, to verify that storage screen work assembly falls rationality and the validity of analytical approach.Carry out the related work of the part manufacture of spent fuel storage rack fall-down test and fall-down test for this reason, both at home and abroad can for reference and reference without detailed data.
Summary of the invention
The object of the invention is to simulate the situation of the produced shock that drops that irradiated fuel assembly drops or regularly loads and unloads other weight during spentnuclear fuel, the automatic releasing device of design invention.
The technical scheme that the design's invention technical solution problem adopts is: a kind of automatic releasing device, comprises axle, spacer, fixed head, roll sleeve, suspension hook, suspension ring etc., it is characterized in that transferring angle by suspension ring, changes the angle of suspension hook, lifting object is come off.
The design's beneficial effect of the invention is: this reality designs invention, does not need to use other electric equipments, and simple manual operation can realize weight and fall behavior, guarantees effectively carrying out of fall-down test.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is the front view of releasing means.
Fig. 1: 1-suspension hook; 2-gland; 3-axle; 4-carries on the back cap M30 × 1.5; 5-dottle pin; 6-dottle pin; 7-fixed head; 8-plug; 9-carries on the back cap M24; 10-unhook plate; 11-suspension ring axle; 12-carries on the back cap M27 × 1.5; 13-hanging sleeve; 14-suspension ring; 15-hanging sleeve; 16-axle.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of automatic releasing device, by weight hanging on suspension hook 1, lifted, relieve the constraint to suspension hook 1 by unhook plate 10, three intersections close real suspension hook opened with certain angle, and weight is come off.The hanging of gland 2, axle 3, back of the body cap 4, dottle pin 5, dottle pin 6, fixed head 7, plug 8, back of the body cap M249, suspension ring axle 11, back of the body cap 12, hanging sleeve 13, suspension ring 14, hanging sleeve 15, axle 16 and rotational structure.
Claims (1)
