Abstract
The utility model relates to a gamma ray pipeline detector, which is composed of a support seat, a ratchet wheel, a detent, a chain wheel, a chain bar, a hanging seat, a lead cover, a basal seat, a gamma source fixed cover, a rubber pad, etc. The utility model is characterized in that the lead cover is sheathed and connected to the basal seat, the hanging seat and the support seat are respectively fixed at the corresponding point of the surface of the lead cover, the ratchet wheel, the detent and the chain wheel are connected with the support seat, one end of the chain bar is connected with the chain wheel, the other end is connected with the hanging seat by using a hanging hook, the rubber pad is connected with the inner wall of the gamma source fixed cover, the point site of the edge of the gamma source fixed cover is connected with the lead cover, and the corresponding point site of the other side is connected with the lead cover by using a screw bolt and a wing nut. The utility model has the advantages of simple structure and convenient operation, and the harm to an operator is reduced.
Description
The utility model is to belong to be used for metallic conduit girth joint defect-detecting equipment.
At present, domestic metallic conduit seam inspection, especially field work, use gamma ray, though light, laborsaving, do not need power supply, simple to operate, because the protection difficulty has to use heavy X-ray production apparatus to be finished.It is for the gamma ray machine, and radiation radius is little, and directionality is strong, and radiation protection is easier relatively, operating personnel is injured less.But it is extremely difficult that X-ray machine is operated in pipeline inspection, and the chemical engineering industry pipeline is erected at the high-altitude mostly, and the X-ray machine of fixing tens kilogram weights is the time-consuming hard work again of part at assigned address, assigned direction.
The purpose of this utility model is to make a kind of gamma ray pipe detection device, is applicable to that the ray film making of pipe welding port detects, and can reduce the injury that ray leaks and brings to the testing staff greatly, improves the labour productivity of flaw detection operation.
The utility model mainly is made up of bearing 1, ratchet 2, ratchet 3, sprocket wheel 4, chain 5, hanging seat 6, plumbous cover 7, base 8, γ source fixed cover 9, rubber cushion 10, bolt 11, wing nut 12, as shown in the figure; It is characterized in that: plumbous cover 7 covers are associated on the base 8, hanging seat 6, bearing 1 are separately fixed at the surperficial corresponding position of plumbous cover 7, ratchet 2, ratchet 3, sprocket wheel 4 connect with bearing 1, chain 5 one ends connect with sprocket wheel 4, the other end connects with hanging seat 6 with linking up with, rubber cushion 10 connects with γ source fixed cover 9 inwalls, fixed cover 9 marginal point places in γ source connect with plumbous cover 7, and the another side corresponding point position connects with plumbous cover 7 with bolt 11, wing nut 12, forms the gamma ray pipe detection device.
The course of work of the present utility model: base 8 of the present utility model is to be stuck on the metallic conduit that is detected, and as shown in the figure, its dotted line is a tested pipeline; Plumbous cover 7 enclosures are on base 8, and its hanging seat 6, bearing 1 are symmetrically distributed, and connection is solid to be covered on 7 surfaces and the base 8 at lead.When needs detected weld seam, base 8 was stuck on the tested pipeline, connected with hanging seat with two chain 5 one ends, and the other end sprocket wheel top with being fixed on bearing 1 connects, and rotating sprocket 4 can tighten base 8 and pipeline, and tightens with ratchet 2, ratchet 3.Open γ source fixed cover 9, the γ source is placed in the plumbous cover, connect, can detect a flaw with bolt 11, wing nut fixing seal.
The utility model compared with prior art, this apparatus structure is simple, and is easy to operate, can make the flaw detection personnel in pipeline ray film making work, do not re-use heavy X-ray machine, is subjected to radiohazard again less.And the gamma ray inspection head side of adding awl prevents that only how many weighs plumbous cover altogether, and it is simply fixing, with two chains lockings, this device can be fixed on the tested pipeline.The protective lead cover is confined to ray in the tapered square tube, and useless ray is absorbed by the lead cover mostly, and useful ray is directed and focuses on the film direction, can make full use of ray, shortens the transillumination time, improves the flaw detection operating efficiency.Because the effect of plumbous cover, x radiation x reduces greatly, has reduced the injury to the flaw detection personnel.Use this device, in the pipe welding port flaw detection, promptly be subjected to the radiation of ray less, can break away from heavy manual labor again, increase work efficiency.
Description of drawings:
Figure is a structural representation of the present utility model.
Embodiment of the present utility model:
The utility model is made up of bearing 1, ratchet 2, ratchet 3, sprocket wheel 4, chain 5, hanging seat 6, plumbous cover 7, base 8, γ source fixed cover 9, rubber cushion 10, bolt 11, wing nut 12, as shown in the figure.Wherein bolt 11, wing nut 12, chain 5 are for selecting part for use; The 7 usefulness stereotype side's of the making tapers of plumbous cover; Ratchet 2, ratchet 3 usefulness steel are made; Bearing 1, hanging seat 6, base 8, γ source fixed cover 9 usefulness steel plates are made wherein base 8 sides of being taper.
Lead cover 7 covers are associated on the base 8, and two hanging seats 6, bearing 1 correspondences connect firmly on lead cover 7, base 8, and sprocket wheel 4, ratchet 2, ratchet 3 connect with bearing 1, and chain 5 one ends connect with hanging seat 6, and an end connects with sprocket wheel 4.A bit connect with lead cover 7 on the edge of γ source fixed cover 9, another point connects with plumbous cover 7 with bolt 11, wing nut 12, forms the gamma ray detection device.
