Abstract

The utility model relates to a medical X-ray inspection arm frame which is composed of a column, a base, a C-shaped bearing frame, X-ray sources arranged at both ends of the C-shaped bearing frame, and an imaging device. The medical X-ray inspection arm frame is characterized in that the column forms a C shape and a circular arc shape. Two circular arc-shaped tracks are arranged on the column. A bracket which can move along the circular path on the column is arranged on the column. The bracket is connected with a supporting shaft. The C-shaped bearing frame is arranged on the supporting shaft and can rotate around the supporting shaft. Simultaneously the C-shaped bearing frame can move along the column following the bracket. The utility model has simple structure. The C-shaped bearing frame can be conveniently adjusted to obtain an optimal image which is required by curative treatment or diagnosis.

One embodiment further specifies below in conjunction with this utility model:

Column 6 is curved to weld after the C word circular arc by channel-section steel and steel plate and makes, and makes steel plate be wider than channel-section steel, and two edges of plate is exposed the arc-shaped rail 18 that channel-section steel forms two projectioies, and column 6 is contained on the base 20 by support 29.On the inwall of carriage 1, be provided with 12 rollers 2 by wheel shaft 23, roller 2 adopts rolling bearing, wherein have 8 rollers to lean against on the both sides of protruding arc-

shaped rail

18,4 rollers lean against on the both sides of column 6 in addition, and roller 2 can roll on the arc-shaped rail 18 and on the both sides of column 6.The wheel shaft 23 of roller 2 is an eccentric shaft, i.e. shaft shoulder 23a and shaft shoulder 23b disalignment, and roller 2 is contained on the shaft shoulder 23a, and shaft shoulder 23b is provided with screw thread, and shaft shoulder 23b passes after the cradle walls fixing by nut 28.When being sleeved on carriage 1 on the column 6, earlier the distance of 2 of every pair rollers is transferred to greater than the distance between column 6 both sides and greater than the width of two arc-shaped rails 18, after the cover bracket 1, rotate shaft shoulder 23b, each roller is leaned against on the column 6 and arc-shaped rail on, screw nut 28 then.Top and root at column 6 are respectively established a

pulley

4 and 19 by pulley base 5, steel wire rope 3 walk around pulley 4 and its two ends, 19 back respectively with base 20 on the output shaft of decelerator 21 and the top of carriage 1 link to each other, carriage is fixed on the column 6.One motor 22 that links to each other with decelerator 21 is housed on base, starter motor 22, carriage 1 can move reposefully at its circular path of column 6 upper edges.Bolster 13 links to each other with carriage 1 by pedestal 7, and bolster 13 stretches to the center of circle of column.C shape carrier also curves C word circular arc by channel-section steel and steel plate and connects and make, and C shape carrier 9 is made two parts respectively, and links to each other by axle sleeve 8.C shape carrier 9 is equipped with a back-up ring 15 after being contained on the bolster 13 by axle sleeve 8 on bolster, 13 of axle sleeve 8 and bolsters are equipped with a pair of rolling bearing 17, can rotate around bolster 13 to guarantee C shape carrier 9.In C shape carrier 9, be provided with reinforcement 27, to prevent 9 distortion of C shape carrier, simultaneously also can pass through reinforcement 27 counterweights, the x-ray source 16 at C shape carrier 9 and two ends thereof and the common center of gravity of imager 10 are overlapped basically on the axis of bolster 13, rotate around bolster 13 to make things convenient for manual adjustments C shape carrier 9.Also can set weight, the x-ray source 16 at C shape carrier 9 and two ends thereof and the common center of gravity of imager 10 are overlapped substantially on the axis of bolster 13 by two ends at C shape carrier.After required irradiating angle mixes up, rotate around fulcrum 13 for preventing C shape carrier 9, axle sleeve 8 radially run through the bolt 26 that there is blind hole 30 on a top, a briquetting 24 that is connected with spring 25 is housed in the blind hole 30, briquetting 24 is pressed on the bolster 13.The degree that compresses of briquetting 24 can be regulated by bolt 26.Axle head at bolster 13 is equipped with a graduated disc 12 by screw 14, and a pointer 11 is housed on C shape carrier.Can be carved with scale with the position of expression carriage 1 on column 6 at column 6.
