Abstract
The utility model provides a draught fan turning clamping tool and relates to a coupling-type power transmission device, which is characterized in that: the base body shape of the draught fan turning clamping tool comprises a pipe-shaped axle clasping clamping body which is formed by two half-pipe shape pipe plates which are buckled, wherein, a force applying handle is fixed at the outer side of one half-pipe shape pipe plate. The draught fan turning clamping tool comprises the pipe-shaped axle clasping clamping body which is formed by two the half-pipe shape pipe plates which are buckled, wherein, the force applying handle is fixed at the outer side of one half-pipe shape pipe plate. When in turning, the clamping tool is fixed on the short section of a shaft coupling device in an aligning way, the clamping tool auto-locks and clamps when in turning by the force applying handle and the clamping tool rotates in a circulating way around the shaft coupling device when in returning, thereby being capable of achieving the turning purpose by repeated operation; the dismounting workload can be effectively reduced, the damage to a draught fan is reduced and the operation is convenient.
Description
Technical field
A kind of blower fan jiggering jig relates to a kind of device of coupler type transfer motion power.
Background technique
At sulfuric acid production system, SO
2The wind conveyer of flue gas is the heart equipment of whole system, is mainly bearing the conveying task of flue gas.In actual production process, blower fan is except conventional maintenance maintenance, and the fan unit turner that also must carry out behind the system shutdown (no matter why reason is stopped) is done.Because stop for a long time, cause SO
2Sour mud on the wind conveyer casing inner wall of flue gas, the impeller sinks, and deposits to bottom of shell and piles up, and causes the sour mud on the impeller inhomogeneous on the one hand, polarization when causing fan operation, and amplitude increases; Cause SO on the other hand
2The wind conveyer impeller of flue gas can't be started or move by sour mud jam.Under the normal condition, must carry out jiggering as long as blower fan stops, even to guarantee the sour mud on the draught fan impeller, impeller is not by sour mud jam.But the SO of band fluid coupling
2The wind conveyer moment of torsion of flue gas is bigger, and general jiggering spanner can't coil at all.Sulfate system SO
2The wind conveyer of flue gas is not usually owing to carry out jiggering for a long time, clean out casing inner acid mud (impeller, inwall) even lay down blower fan import pipe nipple, yet still can't coil, the joint of the coupling between fluid coupling and the blower fan need be removed, processing corresponding mold could be to SO
2The wind conveyer of flue gas carries out jiggering.So not only can increase miantainers' disassemble and assemble work amount, the more important thing is the coaxality that when assembling, must adjust fluid coupling and blower fan.So long-term, fan is caused than macrolesion.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively reduce the disassemble and assemble work amount, reduces the blower fan damage, easy to operate blower fan jiggering jig.
The purpose of this utility model is achieved through the following technical solutions.
A kind of blower fan jiggering jig is characterized in that its base shape comprises by two make-ups and connects the tubulose seize card body that the halfpipe tube sheet that forms forms, is fixed with an effort handle outside the halfpipe tube sheet therein.
A kind of blower fan jiggering jig of the present utility model is characterized in that the tubular plate of halfpipe that two make-ups form, and connects by the fixedly tongue piece make-up that is arranged on the tubular edges of boards of halfpipe with bolt.
A kind of blower fan jiggering jig of the present utility model is characterized in that the described tubular plate of halfpipe that is fixed with effort handle, and line vertically divides three sections short tube couplings of the section of slitting, radially be divided into middle segment length, two ends; Segment length's tube coupling in the middle of it is movable seize card body, and section short tube joint in two ends is fixedly connected with second half tubular bulb crab bolt of make-up, forms fixedly seize card body; Movable seize card body connects with fixing seize card body rotation by the rotational support arm.
A kind of blower fan jiggering jig of the present utility model, it is characterized in that also being provided with the spacing pin of an application of force handle at the fixedly seize card body end that is fixed with the rotational support arm, be provided with the spacing curved bar of an application of force on rotating handle, the pin that the curved bar tail end is provided with slide opening and limit pin hole is slidingly connected.
A kind of blower fan jiggering jig of the present utility model is characterized in that two make-ups connect tubulose seize card body the inner of the halfpipe tube sheet formation that forms with rubber sheet gasket.
A kind of blower fan jiggering jig of the present utility model, the tubulose seize card body that the halfpipe tube sheet that is formed by two make-ups connections forms, a halfpipe tube sheet outside therein is fixed with an effort handle.The jig counterpart is fixed on the coupling pipe nipple during jiggering, and by effort handle, self-locking chucking when jiggering around the coupling rotation of circling round, repeats the purpose that this operation can reach jiggering during rollback.Can effectively reduce the disassemble and assemble work amount, reduce the blower fan damage, easy to operate.
