Description

Technical Field

[0001] The invention belongs to the technical field of mechanical structure design, and in particular relates to a three-dimensional adjustable circular waveguide support structure. Background Art

[0002] In the electron cyclotron resonance heating system, the high-power millimeter wave output by the microwave source needs to be transmitted to the transmitting antenna via a transmission line. The transmission line of the electron cyclotron system is formed by the docking combination of a circular straight waveguide with a length of several hundred millimeters, one meter or even two meters and some other transmission components, and its total length is generally tens of meters or even hundreds of meters. The electron cyclotron system has very high requirements for the collimation of the transmission line, requiring that the axial deviation of the hundred-meter transmission line must not be greater than 0.1 degrees. During the docking installation process, the inclination and offset of the waveguide will excite high-order heterogeneous modes in the transmission line, thereby causing large microwave transmission losses. In severe cases, it may even cause the transmission line to spark, resulting in the failure of the electron cyclotron system to operate normally. Therefore, it is necessary to design a support structure for a circular waveguide that can not only meet the support and fixation requirements of the waveguide, but also meet the precise adjustment requirements of the waveguide placement height, placement angle and left and right offset to ensure the collimation of the long-distance waveguide installation.

[0003] The existing waveguide support structure uses four screws to support the four feet of the support module to adjust the height of the support. The adjustment actions required by the support structure are very cumbersome, and the support cannot achieve a good levelness. In addition, it is also impossible to adjust the left and right and rotation angles. For short-distance transmission systems, the use of this support structure in electronic cyclotron systems has not brought much impact. With the substantial increase in the microwave transmission distance of the current electronic cyclotron system, the problems brought by this support structure, such as long adjustment time, poor adjustment accuracy, and few adjustment dimensions, have become prominent, and it is unable to meet the requirements of the installation alignment system of the 100-meter transmission system. Summary of the invention

[0004] In view of the above problems, the present invention provides a three-dimensionally adjustable circular waveguide tube support to solve the problem that the prior art cannot accurately adjust the position of the waveguide components in the transmission line of the electron cyclotron system in a flexible and precise manner; the present invention has the universal applicability of a support structure with a small adjustment range, and can not only be used for the support of the circular waveguide tube in this case, but can also be used for the adjustable support of components with any curvature and any plane through appropriate improvements.

[0041] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1 to 15 As shown, the present invention provides a three-dimensional adjustable circular waveguide support structure, comprising: an upper clamp 1, a lower clamp 2, a clamp support platform 3, a locking screw 4, a locking nut 5, a support adjustment screw 6, and a support base 7;

[0043] The upper clamp 1 is an arc structure processed in one piece, and a small horizontal platform is extended from the two ends of the arc section, and an upper clamp Φ9 through hole 8 is respectively provided on the two ends of the horizontal platform. The lower clamp 2 is a combined structure of two sections welded together, and the upper half section is an arc section with the same structural size as the upper clamp 1, and a lower clamp M8 threaded hole 9 is provided on its extended horizontal platform; the lower half section is a long strip section with radial sliding strip holes 10 at both ends. The standard M8 screw passes through the upper clamp Φ9 through hole 8, docks with the lower clamp M8 threaded hole 9, and presses to fix the supported circular corrugated tube. The arc size of the arc section of the upper clamp 1 and the lower clamp 2 is determined according to the outer diameter size of the circular waveguide to be supported. The inner surface of the arc section of the upper clamp 1 and the lower clamp 2 can be glued with a rubber pad of moderate thickness, which is used to buffer the pressure on the circular waveguide when the upper clamp 1 and the lower clamp 2 are pressed, to avoid damage to the outer wall of the waveguide due to hard metal contact, and to electrically isolate the entire transmission line from the support system.

[0044] The clamp support platform 3 is an integrally processed T-shaped structure. The upper part of the T-shaped structure is a long strip with M8 threaded holes 11 of the clamp support platform at both ends; the lower part is a solid cylindrical section with an annular guide locking groove 12 on the outer wall of the solid cylindrical section. The standard M8 screw passes through the radial sliding strip hole 10 of the lower clamp 2 and docks with the M8 threaded hole 11 of the clamp support platform. The compression nut plays a role in supporting and fixing the upper clamp 1 and the lower clamp 2. When the clamp support platform 3 is docked with the bracket adjustment screw 6, the radial sliding strip hole 10 of the clamp support platform 3 can realize the adjustment of the bracket in the left and right directions. The left and right travel adjustment range of the bracket in the case of the present invention is 1 cm.

[0045] The bracket adjustment screw 6 is an integrally processed hollow composite cylindrical structure with a smooth inner wall. The upper half is an outer hexagonal hollow cylindrical section with six bracket adjustment screw M6 threaded holes 13 on the side, and the lower half is a hollow cylindrical section with a threaded outer wall. Fig.16As shown, the T-shaped cylindrical section of the clamp support platform 3 is inserted into the cavity of the bracket adjustment screw 6, and the clamp support platform 3 can rotate 360 ​​degrees in the cavity of the bracket adjustment screw 6, thereby driving the upper clamp 1 and the lower clamp 2 to rotate. The threaded section on the outer surface of the locking screw 4 is connected with the bracket adjustment screw M6 threaded hole 13 on the side of the outer hexagonal hollow cylindrical section of the bracket adjustment screw 6. After the locking screw 4 is screwed inward until its end top reaches the bottom of the guide locking groove 12 in the clamp support platform 3, it can be used to fix and lock the clamp support platform 3 to prevent it from rotating.

[0046] The bracket base 7 is a hollow inverted T-shaped structure with an integrally processed inner wall having a threaded structure. The upper half of the inverted T-shaped structure is a cylindrical section, and the lower half is a long strip section. Fig.16 As shown, the external thread 14 of the bracket adjustment screw 6 is butted with the internal thread 15 of the bracket base 7. The locking screw 4 serves as a handle to drive the supporting telescopic screw 6 to rotate in the bracket base 7, so as to realize the lifting and lowering of the bracket adjustment screw 6 relative to the bracket base 7, thereby playing a role in adjusting the height of the circular waveguide bracket. The bracket height adjustment stroke in the case of the present invention is 3 cm. The bracket base 7 has Φ9 through holes 16 at both ends of the long strip section, and the entire bracket structure can be fixed to the standard profile by standard M8 screws. The locking nut 5 is an external hexagonal nut structure, and its internal thread is butted with the external thread 14 of the bracket adjustment screw 6. When the bracket height is determined, the locking nut 5 is rotated to the upper end surface of the bracket base 7 to lock the bracket height.
