Description
Technical field
The utility model relates to the clamp device of a kind of space division rectifying column piston ring, belong to space division rectifying device technology neck
Territory.
Background technology
In air separation cooling box, rectifying column equipment plays a key effect in air separates, and this will ensure rectifying column inner body
The importance installed, in the piston ring installed, column plate, cylinder palpus mutually precision-fit together.But in prior art, rectifying column rises
The installation process of circle cannot effectively control the gap of piston ring and rectifying column cylinder, cause excesssive gap, easily produce welding
Deformation, if excesssive gap will affect the installation accuracy of column plate, ultimately results in the reduction of rectifying column rectification efficiency.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and provides a kind of simple in construction, and installation makes
With convenient, control the gap of cylinder and piston ring, reduce welding deformation, it is ensured that the installation flatness of column plate, improve in installation process
In quality, the clamp device of space division rectifying column piston ring of measure of precision.
The purpose of this utility model completes by following technical solution, the fastening dress of a kind of space division rectifying column piston ring
Put, described piston ring along space division rectifying column cylinder inboard wall arrange, described clamp device mainly by alignment pin, contiguous block,
Pivot pin, locking nut form with locking screw splice combinations, and described left and right two alignment pin is plugged in two contiguous blocks of left and right, and
Integral by being welded to connect；Left and right locking nut is threaded connection with locking screw joint, the left and right two that will connect
Locking nut is inserted in the contiguous block of left and right by respective groove ends, and is fixed with bearing pin, and described left and right two positions
Pin is plugged in corresponding two fabrication holes of piston ring respectively.
As preferably: be provided with on described bearing pin for split pin insertion in case the bearing pin that shotpin axle skids off when using stops
Push hole；Two ends distances of described left and right two alignment pin are by adjusting with the fabrication hole offered on piston ring apart from identical, in order to can make
Left and right two alignment pins insert in corresponding two fabrication holes, and can connect locking screw joint by left and right two and fasten, and make to rise
Circle is fully combined closely with tower body.
This utility model has simple in construction, easy to install, can improve work efficiency and guarantee essence that piston ring is installed
Evaporate the installation quality of tower, can guarantee that the reasonable clearance of piston ring and column plate, reduce the spies such as welding deformation, the rectification effect of raising column plate
Point.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail: shown in Fig. 1, described in the utility model a kind of empty
Dividing the clamp device of rectifying column piston ring, described piston ring 2 is arranged along cylinder 1 inwall of space division rectifying column, described fastening dress
Put mainly by alignment pin 3, contiguous block 4, pivot pin 6,9, locking nut 7,8 combine with locking screw joint 12,13, described
Left and right two alignment pins 3 are plugged in two contiguous blocks 4 of left and right, and integral by being welded to connect；Form a soldering opening 14, by a left side
Right locking nut 7,8 is threaded connection with locking screw joint 12,13, is passed through by left and right two locking nut 7,8 connected
Respective groove ends is inserted in left and right contiguous block 4, and is fixed with bearing pin 6,9, and described left and right two alignment pin 3 is inserted respectively
It is connected in corresponding two fabrication holes of piston ring 2.
Shown in figure, described bearing pin 6,9 is provided with and inserts for split pin 5 in case the pin that skids off when shotpin axle uses
Axle thrust hole；Two ends distances of described left and right two alignment pin 3 by adjusting with the fabrication hole offered on piston ring 2 apart from identical, with
Just left and right two alignment pins 3 can be made to insert in corresponding two fabrication holes, and locking screw joint 12,13 can be connected enter by left and right two
Row fastening, makes piston ring 2 fully combine closely with tower body 1.
This utility model can guarantee that piston ring installation quality, improves efficiency, overcomes the deficiency installing existence before, uses instrument
The locking screw joint on clamp device tightened by adjustable wrench, and the gap of piston ring Yu cylinder is transferred to minimum, and such piston ring is abundant
Combine closely with cylinder, it is simple to cylinder welds with piston ring, reduce welding deformation thus reach the installation that column plate can be smooth,
Improve the effect of rectifying column rectification.
Installation process of the present utility model is:
Inserting in contiguous block top-portion apertures by the alignment pin processed, employing is welded to connect integral；
The left and right locking nut processed is threaded connection with locking screw joint；
The locking nut groove ends connected is inserted in contiguous block, is then fixed with pivot pin；
Split pin is inserted pivot pin thrust hole prevents pivot pin from skidding off when using；
During operation, this device top steady pin two end size is regulated beforehand through nipple with piston ring fabrication hole size
Good, then clamp device is inserted in 2 fabrication holes of piston ring, after fasten by connecting locking screw joint, make piston ring
Fully combine closely with tower body.
