Produce vibrations, cause barral of a gun repeatedly to touch with flow distribution baffle, steam generator flow distribution baffle can be caused damage, shadow simultaneously
Ring damage equipment self.
Summary of the invention
It is an object of the invention to provide a kind of steam generator secondary side the first gripper shoe lower surface hydrodynamic cleaning to guide
Device, connects rigidity after solving the reduction of existing body refuse sluice gun structure of gun barrel size not enough, so that steam generator cannot be adapted to
First gripper shoe lower surface rinsing requirement.
Technical scheme is as follows: a kind of steam generator secondary side the first gripper shoe lower surface hydrodynamic cleaning guides
Device, this device includes guide rail, fixing seat, sliding seat and long bolt, and wherein, guide rail is the rectangle that upper end has grooved tracks
Structure, its right side front forms hook structure；It is fixed with fixing seat on the left of guide rail under rear end, and has screw thread on fixing seat
Hole；Sliding seat on the right side of fixing seat snaps in one section of chute below guide rail；Long bolt sequentially passes through slip on the right side of sliding seat
Seat and fixing seat, and utilize the hook being fixed on sliding seat to compress the end on the right side of long bolt, the screw thread knot on the left of long bolt
Structure matches with fixing seat；By rotating long bolt, sliding seat can be driven to move along guide rail relative to fixing seat.
Described long bolt stretches out and is additionally provided with tight split nut on the thread segment on the left of fixing seat.
The end that described long bolt stretches out on the left of fixing seat is fixed with hex nut.
It is provided with stop screw at described guide rail right side front hook.
It is installed with fixing seat by soket head cap screw A below right-hand member on the left of described guide rail.
Described hook is fixed on sliding seat by soket head cap screw B.
Have unthreaded hole on described sliding seat, and be provided with counterbore.
Described long bolt is paralleled with guide rail.
On described guide rail, slide block is installed.
The remarkable result of the present invention is: a kind of steam generator secondary side the first gripper shoe lower surface of the present invention
Hydrodynamic cleaning guider, uses guide rail structure that body refuse sluice gun gun barrel is supported and is guided, and ensures that sluice gun gun barrel is firm
Property and functional stabilization, it is ensured that not havinging skew during body refuse sluice gun stepping, nozzle can be correctly aligned between pipe, improves the
The flush efficiency of one gripper shoe lower surface and accuracy.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is described in further detail by specific embodiment.
As shown in Figure 1 and Figure 2, a kind of steam generator secondary side the first gripper shoe lower surface hydrodynamic cleaning guider, bag
Including guide rail 6, fixing seat 4, sliding seat 7 and long bolt 2, wherein, guide rail 6 generally upper end has the rectangle knot of grooved tracks
Structure, its right side front forms hook structure, and is provided with stop screw 11, it is to avoid be arranged on the slide block 10 in the track of guide rail upper end
Skid off guide rail 6；Being installed with fixing seat 4 by soket head cap screw A5 below rear end on the left of guide rail 6, fixing seat 4 is in parallel conductive
Screwed hole is had on the direction of rail 6；It is positioned in one section of chute that the sliding seat 7 on the right side of fixing seat 4 snaps in below guide rail 6, is sliding
Have unthreaded hole with the fixing seat 4 same axis of screwed hole of centre on dynamic seat 7, and counterbore is set；Long bolt 2 depends on the right side of sliding seat 7
