Description
Technical field
The utility model is related to a kind of clutch bolt top pressure to clamp, and belongs to the technical field of engineering goods structure；Specifically
Belong to nuclear power station and the special less important work work used when the connection clutch Bolt dismantling operation of water pump and motor is repaired
The technical field of lamps structure.
Background technology
At present in nuclear power station dismounting breakdown maintenance motor, water pump, it is required for first dismantling clutch.Clutch, it is custom
Claim, professional call is shaft coupling and flange, for the connection of plant equipment；Generally, the chain that shaft coupling is used between rotating machinery
Connect, such as the connection between driving machinery motor and dragged mechanical water pump etc., one of its mode is connected using shaft coupling,
Rotary shaft between two equipment is rigidly connected, the rotation of other equipment is driven；Shaft coupling also known as shaft coupling, be for
Connection recruits two axles (driving shaft and driven shaft) in different institutions to be allowed to rotate with the machine components of transmitting torque jointly, plays linking
Effect.In the power transmission of high-speed overload, some shaft couplings also have the work of buffering, vibration damping and raising axle system dynamic property
With.Shaft coupling is made up of two parts, and driving shaft and driven shaft are connected respectively, and general power is mostly by means of shaft coupling and working machine
It is connected.
Because of the gap between motor, the connection clutch of water pump closely, both sides locational space is narrow and small, and conventional tool dismounting is leaned on
The method of bolt is exactly sideling to be struck with copper rod, swung with hand hammer and pounded on backgear, and because gap is small, amplitude of fluctuation is small, and angle is not
Easily grasp, it is easy to strike bad bolt screw thread.More particularly in pump housing equipment moist or with corrosive gas workplace,
Because the shock-absorption rubber sleeve long-term ageing corrosion or corrosion of connecting bolt are sticked, dismounting difficulty is big.Sometimes cannot dismantle really only
Have carries out destructive separation of disintegrating to bolt by complete equipment dismounting to workshop, brings larger difficulty to maintenance work, seriously
Influence the maintenance duration of machine and normal operation production；Clutch dismounting due to troublesome poeration, inefficiency, never phase
The tool special for dismounting of pass.

Because in order to ensure motor, vibration amplitude is small in the course of the work, shaft coupling clutch bolt gland motor side one
As be designed to flat mouth countersunk head type, be installed in place insertion bolt band top nut fastening it is firm after, bolt countersunk head surface and clutch
Inner side does not have any ledge in approximately the same plane, cause demounting bolt this when it cannot be set about, that is, any work
Tool is not all used.When dismantling this bolt only way be exactly from pump housing side come loose clamp nut carry out side position tap move back it
Go out.
Use the technical solution of the utility model and cover and cooperate to solve dismounting motor coupler set and water pump coupler
The bolt job execution difficulty for constituting clutch does technical matters solution, and the deboost work that it uses for reference clamp is former
Reason, is held by hand clencher being pressed, and the grasping active force of hand is delivered to the top push rod of pressure top pincers, and outwards do reversely
Motion.That is, this active force will need the bolt of dismounting to be pushed to return to the direction of insertion, it is loosened or is exited, realize
Dismounting purpose.Traditional dismounting operation technique is the method improve, the screw thread of screw rod will not be destroyed, it is ensured that its screw thread is intact, side
Just dress is returned to be continuing with.The pressure top is clamped it and uses in extensive range, is related to and for the dismounting of the equipment such as nuclear power and civilian pump class
Clutch bolt maintains operation, simple using the tool operation, easy to operate, dismounts fast and flexible, with flexible tune
Whole spacing is adapted to different type pump housing clutch Bolt dismantling, is convenient to the maintenance of equipment, time saving and energy saving, long service life, into
