Description
Technical field
The utility model is the pipe leakage corrosion detector support roller of online detection pipeline metal loss degree, relates to measurement and the pipe-line system technical field of measuring magnetic variable, thickness linear dimension.
Background technique
All can there be corrosion to a certain degree in buried steel pipeline, the particularly service time steel pipe more of a specified duration of operation, for guaranteeing the buried pipeline security of operation, all wants regularly pipeline to be done online corrosion usually and detects.Corrosive pipeline detects and all uses interior detection mode at present, mainly is flux-leakage detection method.This Technology Need have magnet and steel brush with magnetic action in pipeline, could detect, and the magnetic property that will seek out, must be to uniform magnetic conduction be circumferentially arranged in the pipeline, this will guarantee that very heavy whole detector is equidistant with the inner-walls of duct maintenance.In fact very heavy detector causes detector bottom and inner-walls of duct distance little because the effect of gravity is certain to sink, and the top distance is big.And in the existing technology though support roller has been installed also, can play supporting role, this support roller still has some deficits, support roller often has the ineffective situation of rotating, particularly wheel collides wheel carrier sometimes when crossing weld seam, valve, threeway etc., and unnecessary damage takes place; And wheel compression and resilience entad is not steady, and obviously this is to influence the detector proper functioning.
The model utility content
The purpose of this utility model is a kind of online detection pipeline metal loss degree detecting quality height of design, reliable, durable pipe leakage corrosion detector support roller.
Structure of the present utility model is the same with prior art, comprise wheel 2, wheel shaft 20, wheel arm (1) 1, wheel arm (2) 3, spring shaft 16, major axis 33, protective sleeve 17, spring 13, support 12 etc., wheel 2 is fixed between wheel arm (1) 1, wheel arm (2) 3 tops through wheel shaft 20, the middle part of wheel arm (1) 1, wheel arm (2) 3 is rotationally connected by major axis 33 and two locking nuts 4, the root spring shaft 16 that respectively is rotationally connected, and spring shaft 16 passes the hole and the protective sleeve 17 cover upper spring 13 and the end caps 14 of support 12, again by locking nut 26 lockings.Its feature such as Fig. 1, Fig. 2, shown in Figure 3 are in the wheel 2 gear mechanism to be installed, and wheel 2 wheel arm (1) 1, the wheel of side on the lower side is equipped with anticollision mechanism on the arm (2) 3, and spring 13 is a belleville spring.
Wherein the gear mechanism (see figure 4)s of installing in the wheel 2 are by being followed successively by sleeve pipe (3) 25, copper packing (2) 35, bearing 21, copper packing (3) 36, sleeve pipe (1) 24, copper packing (3) 36, bearing 21, copper packing (2) 35, bearing cap 23 from left to right between its rotating shaft and hollow wheel, and wheel shaft 20 is the straight-through type forced filling oil cup 6 of holding head level with both hands, and the other end is the spiral shell button.
And straight-through type forced filling oil cup 6 be at the central shaft of axle to punching through to wheel 2 middle parts, and communicate, through to (1) 24 li of the sleeve pipe at middle part with radially hole.
Wherein take turns the anticollision mechanism of installing on arm (1) 1, the wheel arm (2) 3 and be wheel arm (1) 1 at wheel 2 places, wheel arm (2) 3 on the lower side direction one anti-collision block (1) 10, anti-collision block (2) 11 respectively are installed.Collision block (1) 10, anti-collision block (2) the 11st, by with add steel plate casting all-in-one-piece polyurethane material and make outer end circle, inner end side rectangular, be fixed on the outside of wheel arm (1) 1, wheel arm (2) 3 by adding steel plate and bolt, nut.It is in order to prevent that wheel 2 and support 12 from bumping against, promptly to 2 position-limiting actions of wheel.
But because of the polyester material softer; in order not make anti-collision block (1) 10, anti-collision block (2) 11 excessive pressurizeds; anti-collision block (1) 10, anti-collision block (2) 11 are added the protection limit stoper in addition; promptly also open screw on the arm (1) 1 and be screwed into a hexagon head bolt 8 that is rotary with hexagon nut 9, regulate the length that hexagon head bolts 8 stretch out with hexagon nut 9 top-right wheel of anti-collision block (1) 10.
Wheel arm (1) 1, wheel arm (2) the 3rd, " " " shape plate; be connected with spring shaft 16 hinges by the hole; the spring shaft 16 of joint is a prong; wheel arm (1) 1, wheel arm (2) 3 insert in the prong, the hole on wheel arm (1) 1, the wheel arm (2) 3 is relative with two holes on spring shaft 16 prongs, and penetrates minor axis 29 after being inserted in a wear-resistant sleeve (1) 28; minor axis 29 1 ends have cap; the other end has the spiral shell button, overlap a plain washer 27, and are fastening by locking nut 26.
Support 12 vertical sections are substantially
Shape, other has two set square triangles that the left side and the upper surface plate of support 12 are connected, and the upper surface plate of support 12 middle part is a mounting base.
The structure that wheel arm (1) 1, wheel arm (2) 3 middle parts and major axis 33 are rotationally connected is: thick in the centre, two ends thin and have among the major axis 33 of spiral shell button between thick section, overcoat wear-resistant sleeve (2) 30, and at the two ends of wear-resistant sleeve (2) 30 each twists solid packing rings (3) 32 by fluting awl end Cock screw 31, interior side contacts with two-wheeled arm (1) 1, wheel arm (2) 3, after two-wheeled arm (1) 1, wheel arm (2) 3 were passed in the two ends of major axis 33, each overlapped a plain washer 5 and twists solid by locking nut 4.
Locking nut 4 wherein and locking nut 26 are non-metallic insert; Bearing 21 is the dustproof deep groove ball bearing of one side.
Structure so, after 4-12 supporting wheel evenly is installed on the detector, wheel 2 since the effect of belleville spring 13 be pressed on the inwall of pipeline, and certain support force arranged, detector is supported on the center of pipeline, keeps the equidistant of detector and inner-walls of duct, to guarantee to detect quality.Can be as for support force according to the weight of detector, by the appropriate design decision of two belleville springs 13.Simultaneously, when support roller is crossed weld seam, valve etc., be equivalent to wheel 2 to be subjected to pipeline power radially, wheel 2 moves to die, wheel arm (1) 1, wheel arm (2) 3 serve as that axle rotates with major axis 33, make belleville spring 13 pressurizeds on the spring shaft 16, still can keep the equidistant of detector and inner-walls of duct; Cross weld seam as one of them support roller, only this supporting wheel is subjected to pipeline power radially, because the acting in conjunction of other supporting wheel also can keep the equidistant of detector and inner-walls of duct, does not still influence the detection quality of detector.
Therefore this supporting wheel is reasonable in design, and is reliable, durable, detector can be supported on the center of pipeline, keeps the equidistant of detector and inner-walls of duct, to guarantee to detect quality.Thereby this support roller makes detector improve the detection quality reliably.
