Abstract

The utility model provides an X-ray online checking device used for checking the thickness of a cable insulation layer, comprising an X-ray transmitter and a radial receiver which are arranged at two sides of the cable. A transmitter head is fixedly matched with the receiver, and the transmitter head can slide along a straight line which is vertical to the cable axes, and then a dynamic surveying to the thickness without loss to the cable continuous manufacturing can be carried out. The utility model solves the hidden trouble to quality that an eccentricity of the cable cannot be timely detected in the manufacturing process to lead the cable scrap or the using accidents.

Description

The online cable insulation measuring thickness device of X-ray

Technical field

The utility model relates to a kind of X-ray on-line detector that circular bar-shaped manufacture of materials detects that is used for, and produces the thickness of insulating layer on-line measuring device continuously in particular for cable.

Background technology

Now, China cable market is very huge, very many cable manufacturers are arranged, but many production equipments are monopolized by external, the checkout equipment that comprises cable insulation Thickness Measurement by Microwave or eccentric quality, generally speaking, the production principle process of crosslinked cable is such, three extruding machines are by an extrusion moulding of mould (three-layer co-extruded), the back is by reaching the stainless steel pipes more than 60 meters, under the effect of high temperature (about 250 degree) and high pressure (about 20 atmospheric pressure) and crosslinking chemical, form, most at present production units adopts empirical range estimation detection means to the check of three-layer co-extruded degree of eccentricity, technical appraisement department is detected for the sampling section the main means of eccentricity detecting of three layers of integument of crosslinked cable at present, and these all are destructive methods, are not fit to dynamic online detection.

The negative effect that the off-centre of cable insulation is brought: each layer thickness deviation of cable product integument forms the serviceable life that off-centre (being commonly called as the oblique supercilious look) directly influences cable, what situation was serious will produce puncture, not only can cause suitable accident, more cause each field to cause a large amount of indirect economic loss because of having a power failure.

Because the product whole process of production can't can both rely on range estimation to carry out parameter constantly and mould is corrected, finally be difficult to avoid problem, when discovered, produce and finish, like that a large amount of final results of scrapping have been inevitable, and also will spend great amount of manpower and material resources to the recycling of waste product.

The utility model content:

The utility model provides the online cable of a kind of X-ray continuous production testing device, thereby solved in the production run dynamic thickness measuring and found that in time the eccentric cable of avoiding of cable scraps or the hidden danger of quality of use accident.

The utility model is achieved in that a kind of online cable detecting device, comprises X-ray transmitter and ray receiver, is respectively in the both sides of cable, and transmitter and receiver are secure fit.

Its improvement can also be: the emission head can be along the linear slide perpendicular to cable axis.

Its improvement can also be: the propelling of linear slide is that leading screw advances.

Its improvement can also be: also comprise the straight line transverse-moving mechanism, the straight line transverse-moving mechanism is surveyed the headstock by electromagnet one end power-on boot and is produced straight line back and forth movement from left to right along the straight line track.

By above-mentioned improvement, the X-ray line from emitting head to accepting head, the centre penetrates the insulation course of cable, because decay and the X-ray of X-ray in insulation course has positive correlation at the insulation course penetration range, by measuring the opto-electronic conversion of accepting the X-ray flux on the head, just can measure the thickness or the degree of eccentricity of insulation course effectively, because pick-up unit and quantity-produced cable are contactless state, do not influence production run, the off-centre of any insulation course all will in time obtain reflection simultaneously, significantly reduce the quantity of defective cable, produced huge economic benefit.

Embodiment

Below in conjunction with accompanying drawing the utility model is made more detailed description.

The utility model is achieved in that a kind of online cable detecting device as shown in Figure 1 to Figure 3, comprises that X-ray transmitter 4 and ray accept 1, is respectively in the both sides of cable 6, a transmitter 4 and accept 1 and be secure fit by web joint 3.Transmitter 4 can be along the linear slide perpendicular to cable axis.The propelling of linear slide is that leading screw 2 advances.The straight line transverse-moving mechanism is surveyed the headstock by electromagnet one end power-on boot and is produced straight line back and forth movement from left to right along the straight line track.

The X-ray line from transmitter 4 to accepting 1, the centre penetrates the insulation course of cable 6, because decay and the X-ray of X-ray in insulation course has positive correlation at the insulation course penetration range, by measure accepting the opto-electronic conversion of the X-ray flux on 1, just can measure the thickness or the degree of eccentricity of insulation course effectively.

Claims

1. online cable insulation measuring thickness device of X-ray, it is characterized in that: comprise X-ray transmitter and ray receiver, be respectively in the both sides of cable, transmitter and receiver are secure fit.
