First embodiment
Referring to fig. 1 to 3, a C-arm swiveling apparatus provided by an embodiment of the present application includes a C-arm 100 and a mounting base 200 for mounting the C-arm, wherein two side surfaces of the C-arm 100 are respectively provided with an arc-shaped track 110, and the C-arm 100 is configured to rotate around an axis of the C-arm 100 relative to the mounting base 200. The mount pad 200 includes arm support 220 and the axial support bearing 210 that sets up in pairs, and arm support 220 passes through axial support bearing 210 and moves along C shape arm 100, specifically, the axial support bearing rotates to be connected on the arm support, the axis of the directional C shape arm 100 of center pin of axial support bearing 210, and side laminating arc track 110, axial support bearing 210 can roll along the arc track 110 of both sides face respectively.
It should be noted that, in this embodiment, the surface of the C-shaped arm 100 is divided into an inner wall, an outer wall and two side surfaces, the inner wall and the outer wall are both curved surfaces and are parallel to the axis of the C-shaped arm, the side surfaces are planes, and the planes where the side surfaces are located are perpendicular or nearly perpendicular to the axis of the C-shaped arm; accordingly, in the present embodiment, "axis" refers to a straight line around which the C-arm 100 rotates, and "central axis" refers to a symmetrical axis passing through the center of rotation, similar to the axial direction in a cylinder; in this embodiment, the middle of the side surface of the C-arm 100 is recessed inward to form a groove-shaped structure, which is called a revolving groove, the bottom surface of the revolving groove is the arc-shaped track 110, and the side surface of the arc-shaped track 110 in this application is substantially the side surface of the revolving groove.
In the embodiment of the present application, the axial support bearing 210 is in the shape of a circular truncated cone having a radius r1 First end surface 211 and a radius r2 Second end face 212 of height h, and r1＜r2(ii) a The central axis of the axial support bearing 210 is directed toward the axis of the C-arm 100, and the lateral surface of the axial support bearing 210 is rolled along the arc-shaped track 110. The first end surface 211 is at a distance R from the axis of the C-arm 1001 Second end face 212 is spaced from the axis of C-arm 100 by a distance R2And R is1＜R2. The vertex angle of the cone corresponding to the axial support bearing 210 is 2 α, tan α ═ r2-r1) H is used as the reference value. In particular, the "distance from the first end surface 211 to the axis of the C-arm 100" means the distance from the center of the first end surface to the axis of the C-arm 100, and similarly, the "distance from the second end surface 212 to the axis of the C-arm 100" means the distance from the center of the second end surface to the axis of the C-arm 100.
When the C-arm 100 is rotated about the axis of the C-arm 100 relative to the mount 200, the central axis of the axial support bearing 210 is directed toward the axis of the C-arm 100 to ensure that the axial support bearing 210 rolls with the rotation of the C-arm 100 without interfering with the rotation of the C-arm 100.
When the circular truncated cone-shaped axial support bearing 210 rolls on the arc-shaped track 110, the linear velocities of the side surfaces of the axial support bearing 210 at different positions from the central axis are different, the linear velocity at a position close to the central axis is large, and the linear velocity at a position far from the central axis is small, that is, in the axial support bearing 210, the linear velocity of a part with a small radius is large, and the linear velocity of a part with a large radius is small. When the axial support bearing 210 rolls, the part with the small radius is close to the axis, and the part with the large radius is far away from the axis (see fig. 3); this arrangement can greatly reduce or even avoid the sliding friction between the axial support bearing 210 and the arc-shaped rail 110, and reduce the maintenance cost of the C-arm 100. Illustratively, r in the present embodiment1/r2＝R1/R2At this time, sliding friction is not generated between the axial support bearing 210 and the arc rail 110, so that it is possible to minimizeThe maintenance and service costs of the C-arm 100 ensure the useful life of the C-arm 100.
In addition, in the embodiment of the present application, since the axial supporting bearing 210 is in the shape of a circular truncated cone, in order to make the side surface of the axial supporting bearing 210 fit the arc-shaped rail 110, the vertex angle of the cone corresponding to the axial supporting bearing 210 must be a specific angle so that the side surface of the axial supporting bearing 210 fits the arc-shaped rail 110, and when the vertex angle of the cone corresponding to the axial supporting bearing is 2 α and tan α ═ r (r ═ r), the vertex angle of the cone corresponding to the axial supporting bearing is 2 α2-r1) When the axial support bearing 210 is in contact with the arc rail 110, the side surface of the axial support bearing 210 can be completely attached to the arc rail 110, and the included angle value between the central axis of the axial support bearing 210 and the arc rail 110 is alpha; the value of the included angle α between the central axis of the axial support bearing 210 and the arc rail 110 can be achieved by tilting the axial support bearing 210 or tilting the arc rail 110. Illustratively, in this embodiment, the arc-shaped track 110 is inclined at an angle α with respect to the central axis of the axial support bearing 210, and the central axis of the axial support bearing 210 is disposed perpendicularly with respect to the axis of the C-arm 100 (see fig. 4).
In addition, in the embodiment of the present application, the mounting base 200 further includes a radial positioning bearing 230, and the radial positioning bearing 230 is cylindrical, is disposed in the rotary groove, and can roll along the side surface of the rotary groove; the central axis of the radial positioning bearing 230 is perpendicular to the central axis of the axial support bearing 210, with a gap between the axial support bearing 210 and the radial positioning bearing 230 (see fig. 1).
The radial positioning bearing 230 provided in the swivel groove can fix the position of the C-arm 100 in its radial direction so that the C-arm 100 does not shake in its radial direction (the radial direction of the C-arm 100 means a direction passing through the axis of the C-arm 100 in a radial plane, similar to the radial direction in a cylinder); while the radial direction positioning bearing 230 can roll along the side of the rotation groove, the radial direction positioning bearing 230 can roll at the same angular velocity without hindering the rotation of the C-shaped arm 100 when the C-shaped arm 100 rotates. The central axis of the radial positioning bearing 230 is perpendicular to the central axis of the axial supporting bearing 210 with a gap therebetween, which ensures that the axial supporting bearing 210 and the radial positioning bearing 230 will not affect each other during rolling. By the combined action of the axial support bearing 210 and the radial positioning bearing 230, the C-arm 100 can be constrained in the axial and radial directions, so as not to shake while rotating.
In the embodiment of the present application, the arm support 220 is provided with a fixing seat 221, and the axial support bearing 210 and the radial positioning bearing 230 are respectively rotatably connected to the fixing seat 221. It should be noted that the axial support bearing 210 and the radial positioning bearing 230 in the embodiment of the present application are configured to match with the fixing bases 221, and each fixing base 221 is rotatably connected with the axial support bearing 210 and the radial positioning bearing 230, so that the fixing bases 221 and the radial positioning bearings 230 are also disposed on two sides of the C-shaped arm 100 in pairs. The fixing seat 221 can fix the positions of the axial support bearing 210 and the radial positioning bearing 230 on the arm support 220 without causing the axial support bearing 210 to shake and also without hindering the rotation of the axial support bearing 210 (see fig. 1 and 2).
The arm support 220 can support the weight of the C-shaped arm 100, so that the C-shaped arm slewing device is more stable; the axial support bearing 210 is rotatably coupled to the fixing base 221 of the arm support 220, so that the C-arm 100 can rotate relative to the mounting base 200 even if the mounting base 200 is fixed.
The DSA equipment is prepared by loading the X-ray emitting device and the X-ray receiving device on the two ends of the C-shaped arm slewing device in the first embodiment, and setting r1Is 41.2092mm, r2Is 42mm, R1Is 938mm, R2956mm, h is 18 mm. The DSA equipment has long service life and low maintenance cost; the lubricating agent is rarely used for lubricating and maintaining the equipment, so that the pollution to the DSA equipment is reduced, and the subsequent use is facilitated.
