Screw thread is fixedly connected with base center；Top is derotation screw thread, is fixedly connected with sleeve；The middle position of screw rod is uniformly distributed
There are 4 threaded holes；4 handlebars are uniformly mounted on screw rod；U-shaped frame is fixed on the outside of sleeve；Guide rod upper end is fixed on U
The lower end of shape frame.
Pedestal as described above is disc, and there is the threaded hole of a dextrorotation in disk middle, and there are two threaded hole two sides
The pilot hole of upper diameter 6mm, lower diameter 9mm are symmetrical, and guide rod is passed through from the hole, and disk surrounding is evenly distributed with
The hole of 4 diameter 56mm.
Guide rod as described above is the screwed cylindrical body in top, and guide rod lower part passes through the pilot hole of pedestal, on
Portion is fixedly connected by screw thread with U-shaped frame.
U-shaped frame as described above, unilateral side section are U-shaped, and opening width 96mm, respectively there are a U-shaped in side two sides
Opening, opening width 40mm；One circular hole is arranged at bottom, is fixedly connected with sleeve outside.
The utility model has the beneficial effect that compared with prior art
The utility model is suitable for the different push rods occasion different with height, can also increase cushion block in lower section when needed
To meet higher-height occasion, and the trunnion for locking push rod can be kept fixed by adjusting height, in actual use can
It is enough to remove or install within ten minutes a positioning pin, it greatly improves work efficiency, reduces the risk of equipment damage, protect
The repair quality of key equipment is demonstrate,proved.

In figure: 1, pedestal；2, spiral regulating device；3, handlebar；4, U-shaped frame；5, sleeve；6, guide rod.
Specific embodiment
A kind of height-adjustable fixation bracket is described in detail in the following with reference to the drawings and specific embodiments:
As shown in Figure 1, Figure 3, a kind of height-adjustable fixation bracket, including pedestal 1, spiral regulating device 2, handlebar
3, U-shaped frame 4, sleeve 5 and guide rod 6；Wherein, 2 lower part of spiral regulating device is dextrorotation screw thread, and top is derotation screw thread, intermediate
It is evenly distributed with 4 screw holes；Handlebar 3 is mounted on spiral regulating device 2 by 4 screw holes, for conveniently rotating spiral shell by hand
Tune regulating device 2.Pedestal 1 is the disk of 45mm diameter 180mm one high, and there is the threaded hole of a dextrorotation in disk middle, with
The lower thread of spiral regulating device 2 cooperates；There are two upper diameter 6mm, the pilot holes pair of lower diameter 9mm for threaded hole two sides
Claim distribution；Disk surrounding is evenly distributed with the hole of 4 diameter 56mm, for mitigating disk weight.Lead on the outside of U-shaped frame 4 and sleeve 5
Welded connecting is crossed, the top of internal screw thread and spiral regulating device 2 on sleeve 5 is threadedly engaged；Guide rod 6 is from pedestal
It is passed through in hole, top is connected through a screw thread with U-shaped frame.When adjusting height by handlebar 3, since guide rod 6 is to U-shaped
The restriction effect of the direction of rotation of frame 4, spiral regulating device 2 can only be such that U-shaped frame moves up and down without rotating movement.
As shown in Fig. 2, 4 section of U-shaped frame is U-shaped, opening width 96mm, respectively there are the opening of a U-shaped, opening width in two sides
40mm.Trunnion is placed in the opening of the 96mm of U-shaped frame 4, and there are cylindrical protrusions in trunnion two sides, is placed on two width and is
In the U-shaped opening of 40mmm.
As shown in Figure 4, Figure 5, a kind of height-adjustable when rotation spiral regulating device 2 (seen from above) clockwise
Fixation support height become smaller, until the screw thread of 2 lower part of spiral regulating device is all screwed into pedestal, 6 bottom of guide rod is not at this time
It can be more than the extreme lower position of pedestal, prevent damage guide rod 6；When rotation spiral regulating device 2 (seen from above) counterclockwise,
A kind of height-adjustable fixation support height becomes larger, until the step of 6 lower part of guide rod encounters the step in 1 pilot hole of pedestal
When stop, preventing the screw thread of spiral regulating device 2 from disengaging out of pedestal 1 and sleeve 5 screw hole completely.
As shown in figure 4, U-shaped frame 4 is in minimum position；As shown in figure 5, U-shaped frame 4 is in highest position；In design,
A kind of height-adjustable support bracket fastened height-adjustable range is 36mm.
A kind of height-adjustable support bracket fastened material is common stainless steel, and hardness is than locking push rod trunnion
The hardness of 630 stainless steel of material is low, therefore locking push rod trunnion will not be damaged in operating process.
The utility model is suitable for the locking push rod trunnion fixed pin of the CANDU6 type heavy water reactor push rod of Canada's design
Remove, not by practical operation when height influenced, and it is fixed, can remove or install within ten minutes and once position
Pin, greatly improves work efficiency, reduces the risk of equipment damage.
