Background technology
The maintenance of current power enterprise is most of to be had been carried out standardizing, the maintenance procedure that has standard, the maintenance item for having standard
Mesh, high pressure add people's device to need to dismantle manhole cover before overhauling, and existing manhole cover method for dismounting step is：（1）Will with 2 M24 bolts
Manhole door provision for disengagement is fixed on manhole collar, and provision for disengagement is connected with manhole cover with 1 M24 bolt, and with suitable hand
Cucurbit branch device for hoisting is drawn, assists to remove manhole cover；（2）Remove the stud and pressing plate of fixed manhole cover；（3）Unclamp manhole
Lid, pushes it into hydroecium, then must take appropriate protection in order to avoid damaging manhole cover, rotate attaching/detaching apparatus in the counterclockwise direction
Screw rod exited, always rotation go down until manhole cover and attaching/detaching apparatus are adjacent to；（4）Stretch out one's hand manhole cover edge in hydroecium
Any one direction is rotated by 90 °, and reserves gap, to take out manhole cover from oval mouth；
（5）Manhole cover carefully is exited through manhole with chain block, manhole cover is pulled down from device.But disassembly process needs
Substantial amounts of manpower is wanted, and needs the effect by electric hoist, operation is difficult, task is heavy and heavy workload.
The content of the invention
In order to solve the above-mentioned technical problem the utility model provides a kind of manhole cover tool special for dismounting, time saving and energy saving, behaviour
Make easy.
The technical solution of the utility model is：A kind of manhole cover tool special for dismounting, including fixed arm, dismantling screw, shifting
Dynamic screw rod, revolving part, the fixed arm are bolted on manhole cover periphery, the dismantling screw nose threads and manhole cover
The bolt at middle part matches, and the instrument manhole cover is linked together by dismantling screw, the mobile screw passes through fixed arm
On mounting hole realize it is detachable by mobile screw with dismantling screw with the connection of revolving part, dismantling screw, the revolving part
Link together, the fixed arm is fixed together with revolving part by pin, the revolving part under the action of mobile screw, with
Selling can be rotated for axis.
Further, the revolving part top is provided with handle to scheme.
Further, the revolving part is hollow structure to scheme.
Further, the mobile screw can carry out the length adjustment of dismantling screw by screwing, unscrewing to scheme.
The utility model has the advantages that：The utility model is by the length adjustment of dismantling screw by manhole cover push-in or drawing
Manhole, realizes that revolving part rotation drives manhole cover to rotate, instrument is light, easy to operate, greatly by moving left and right for mobile screw
It is big to save manpower and materials, shorten the repair time, improve work efficiency.
