X-ray inspection detects unwheeling
Technical field
The present invention relates to a kind of X ray detector device specialized equipment, relate in particular to the unwheeling that a kind of x-ray inspection detects usefulness.
Background technology
Unwheeling at present is column or planer-type support body mostly, the unwheeling of this structure is used widely in the ray industry, though can satisfy the height stroke of client's needs, but the unwheeling overall height is excessive, neither attractive in appearance also inconvenient, particularly when needs mobile unwheeling at any time, can bring a lot of inconvenience.Jitter phenomenon can occur in addition in X-ray tube or image amplifier lifting process, influence detects effect.
Summary of the invention
Detect the problem that unwheeling exists at existing x-ray inspection, the invention provides a kind of requirement that can satisfy the client to the height stroke, and can overcome X-ray tube or the jitter phenomenon of image amplifier in lifting process, can cooperate X-ray tube to use the also unwheeling that can cooperate image amplifier to detect.
Addressing the above problem the technical scheme of being taked is:
A kind of x-ray inspection detects unwheeling, it is characterized in that: constitute frame main body by two inner columns (6) and two outer columns (7), leading screw (1), chain (2), screw (3), pulley (5) constitutes the elevating drive mechanism of unwheeling, two outer columns (7) are fixed on the movable pedestal (13), the lower end of two inner columns (6) is fixedly connected by screw (3), motor (4) is fixed on the movable pedestal (13), an end that is fixed on the inboard chain (2) of inner column (6) bottom is connected with lifter slide (11), the other end is connected with inner column (6), pulley (5) is fixed on the inner column (6) by stand column and beam (19), the runner (17) of base (13) is furnished with locking device (18), positioning and guiding wheel (8) and positioning and guiding wheel (9) are fixed on the inboard of inner column (6) bottom, positioning and guiding wheel (10) is fixed on the stand column and beam (19), positioning and guiding wheel (12) is fixed on the lifter slide (11), positioning and guiding wheel (16) is fixed on the upper end of outer column (7) lateral surface, Y-axis whirligig (14) is fixedlyed connected with the support front end of lifter slide (11) by turning axle (20), X-axis whirligig (15) is made up of inside and outside two-layer circle, the Rolling bearing (23) that inner layer ring (22) is rotated relative to outer circle (21) is housed between the two-layer circle, and outer circle (21) links together with Y-axis whirligig (14).
Beneficial effect of the present invention: the present invention adopts the two-layer double-deck elevating mechanism that can relative motion of inner column and outer column, and it is little to take up an area of the space, and landing is flexible, and running is stable, and the unwheeling overall height reduces, and is very convenient in mobile handling process; The travelling block principle is adopted in unwheeling, has improved the rising or falling speed that ray tube or image strengthen greatly, thereby shortens sense cycle; Adopt multipoint positioning, the leading screw chain is the kind of drive simultaneously, the many places locating wheel makes the lifting that elevating mechanism can be stable, has reduced the jitter phenomenon of unwheeling ray tube or image amplifier in lifting process greatly; Adopt two place's rotating mechanisms, but make X-ray tube X-axis, Y direction in unwheeling rotate 360 °, make things convenient for the user in use to select proper angle to detect; When detection workpiece height was big, the adaptability of this mechanism was strong, is fit to the needs of various higher detected parts, and elevating mechanism can carry the X-ray tube or the image amplifier of various models.

Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
A kind of x-ray inspection detects unwheeling, as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and shown in Figure 8, constitute frame main body by two inner columns 6 and two outer columns 7, leading screw 1, chain 2, screw 3, pulley 5 constitutes the elevating drive mechanism of unwheeling, two outer columns 7 are fixed on the movable pedestal 13, the lower end of two inner columns 6 is fixedly connected by screw 3, motor 4 is fixed on the movable pedestal 13, under the effect of motor 4, leading screw 1 begins rotation, by with screw 3 screw the realization lifting action because screw 3 is fixed together with inner column 6, the rising of screw 3 just is equivalent to the rising of inner column 6.Has relative motion relation between inner column 6 and the outer column 7, because it is motionless that outer column 7 is fixed in base, so inner column 6 is directly being taken turns by positioning and guiding under 8,9,10,16 prerequisites of locating with outer column 7, by the rotation of leading screw 1, inner column 6 does relative motion with outer column 7.Adopt the two-layer double-layer lifting system that can relative motion of this inner column and outer column, it is little to make the present invention take up an area of the space, landing is flexible, running is stable, and the unwheeling overall height reduces, and the stroke that raises if desired is 6m, the column of old-fashioned unwheeling will be higher than 6m, and the present invention is owing to be inside and outside two-layer column, and the outer column of unwheeling and inner column respectively reach the stroke that just can satisfy 6m about 3.5m, and be very convenient in mobile handling process.An end that is fixed on the inboard chain 2 of inner column 6 bottoms is connected with lifter slide 11, and the other end is connected with inner column 6, and so the lifting by inner column 6 just can drive moving of lifter slide 11, thereby drives the lifting of X-ray tube or image amplifier.Pulley 5 is fixed on the inner column 6 by stand column and beam 19, and when inner column 6 rose, pulley 5 rose, thereby drives chain 2 transmissions, and the chain 2 that is used for connecting lifter slide 11 has been realized the principle of travelling block by the guiding of pulley 5.Because the travelling block principle is adopted in unwheeling, improved the rising or falling speed that ray tube or image strengthen greatly, thereby sense cycle is shortened.In order to satisfy the requirement of client's mobile unwheeling at any time, the present invention on can arbitrarily angled mobile base 13, arrives the frame overall fixed when being fit to the detection position, and the runner 17 of this base is furnished with locking device 18, plays positioning action, prevents that unwheeling oneself is mobile.In addition in the lifting process of lifter slide 11, at inner column 6 and the outer column 7 easy positions that the direction skew takes place many places have been installed and have guaranteed that all directions play the positioning and guiding wheel of positioning and guiding effect, guarantee the positioning and guiding effect of all directions, thereby reduced ray tube or the image amplifier jitter phenomenon in lifting process, improved detection effect and accuracy of detection.Wherein, positioning and guiding wheel 8 is fixed on the inboard of inner column 6 bottoms, and wheel outer ring and outer column 7 medial surfaces are tangent; Positioning and guiding wheel 9 is fixed on the inboard of inner column 6 bottoms, and wheel outer ring and outer column 7 inner planes are tangent; Positioning and guiding wheel 10 is fixed on the stand column and beam 19, and the interior channel-section steel outerplanar of wheel outer ring and stand column and beam is tangent; Positioning and guiding wheel 12 is fixed on the lifter slide 11, and the interior channel-section steel inner plane of wheel outer ring and lifter slide 11 is tangent, and positioning and guiding wheel 16 is fixed on the upper end of outer column 7 lateral surfaces, and wheel outer ring and inner column 6 lateral surfaces are tangent.Y-axis whirligig 14 rotates by fixing also can the realization of the turning axle 20 and the support front end of lifter slide 11, the skin circle 21 and the Y-axis whirligig 14 of X-axis whirligig 15 weld together, X-axis whirligig 15 is made up of inside and outside two-layer circle, Rolling bearing 23 is housed between the two-layer circle, after installing X-ray tube, rotate by manually making inner layer ring 22 enclose 21 relative to skin, thus the rotation of realization ray tube.The present invention adopts two place's rotating mechanisms, but makes X-ray tube X-axis, Y direction in unwheeling rotate 360 °, makes things convenient for the user in use to select proper angle to detect.
