Abstract

The utility model discloses a movable flaw detector support for a pipeline, comprising a bracket whose upper end is provided with an arc shaped slipway, and the slipway is provided with a roller bracket with a roller; the bracket is also provided with two reels, and each reel is provided with a steel cable; the bracket is provided with a worm shaft and two worm wheels which are engaged with the worm shaft; the worm shaft is fixedly provided with a clamping plate whose lower end is provided with a rotary wheel. The bracket is also provided with four wheels which can roll along the circumferential direction of the outer surface of a pipe and four wheels which move along the longitudinal direction of the pipe. The utility model can be used by matching with an x-ray generator, an x-ray receiver and an imaging system to directly observe welding seams.

Description

Movable flaw detector support for pipeline

The utility model belongs to Handling device, relates to a kind of packaged type pipeline defectoscope carriage.

Radiographic inspection is to detect a kind of basic means of pipe weld, and at present, radiographic inspection mainly contains two kinds, a kind of is that ray generator is fixed on the pipe outside with a simple support, sensitive film is attached to the pipe opposite side relative with ray generator, sends ray with ray generator then, make the film exposure, like this, detect a weld seam, many films also will be changed simultaneously in the position that will repeatedly align generator, so not only troublesome poeration, and cost is also high.Another kind method is that ray generator is placed on tube interior, creep in pipe by cover propulsion system, each bar weld seam is all carried out circumferential exposure, such way one is limited by caliber, the 2nd, by foreign object in pipe ray generator is blocked easily, cost is also still very high simultaneously.In addition, the angle of beam and crack planes has relation in the gamma ray material testing, when the direction of beam is substantially parallel with crack planes, manifesting of crackle with very clear, and the angle of the two just is difficult to find during greater than 15 °, and the direction that existing ray detection method produces ray is changeless, so be easy to cause the omission of crackle, and crackle is the dangerous defects of maximum in the weld seam, is not fill to be permitted to occur crackle in the weld seam.

The purpose of this utility model is to overcome defective of the prior art, provide a kind of and can carry out fast pipe weld, accurately, continuous probe, and the packaged type pipeline defectoscope carriage that can be used with camera system.

The utility model is achieved in that it has a support, the upper end of support is connected with the slideway of an arc, a rolling wheel support that has roller that can move along slideway is installed on slideway, on support, also has two lines wheels, on each line wheel, steel cable is arranged all; A worm shaft and two worm gears that mesh with worm shaft also are installed on support, are fixed with clamping plate on worm-wheel shaft, the clamping plate lower end is equipped with runner.

The utility model has the advantages that simple in structure, can make beam translation-angle, detection speed fast.

Fig. 4 is the B-B cut-open view of the utility model Fig. 3.

Describe in detail below in conjunction with accompanying drawing:

The utility model has a support 8, be fixed with a camber slideway 10 in the upper end of support 8, a support 11 that has roller is arranged on slideway, the ray generator 1 that is used for sending ray can be installed on rolling wheel support 11, also roller 3 is installed in support 8 upper ends by rotating shaft 2, roller 3 can vertically move at outer tube surface, is connected with a ray receptacle 9 during use in the support lower end.Four rolling 5 also is installed on support 8, and this four rolling can circumferentially roll along pipe.A worm shaft 12 also is installed on support 8, also be fixed on the support 8 with the worm gear 13 of worm shaft 12 engagements, be fixed with clamping plate 14 on the worm-wheel shaft, clamping plate 14 lower ends and wheel shaft 4 ' be fixed together, can drive clamping plate 14 when worm gear 13 rotates rotates, and by clamping plate 14 and wheel shaft 4 ' drive wheel 4 liftings, two line wheels 6 also are installed on support 8, on each line wheel 6, all be wound with steel cable 7, during use the wire rope other end walked around pipe to be measured and be fixed on the support upper end, it is fixed carriage and pipe, with axle 12, the wheel shaft of line wheel 6 and wheel shaft 4 ' be connected with corresponding motor respectively.Circumferential when mobile when needs, wheel 5 is rotated, package unit will circumferentially move along outer tube surface; Rotatable worm shaft 12 when need vertically move, and, force wheel 5 to break away from tube surfaces by worm gear 13, clamping plate 14 and wheel shaft 4 ' drive wheel 4 declines, can vertically move along pipe then.

Claims

1, a kind of packaged type pipeline defectoscope carriage comprises support, it is characterized in that: the slideway of an arc is arranged in the upper end of support, a rolling wheel support that has roller is arranged on slideway; On support, also have two line wheels, on each line wheel, steel cable is arranged all; A worm shaft and two worm gears that mesh with worm shaft are installed on support; On worm-wheel shaft, be fixed with clamping plate, the clamping plate lower end is equipped with runner.

2, according to claim 1, it is characterized in that: four wheel and four wheels that vertically move along pipe that circumferentially roll along outer tube surface are arranged on support.
