As shown in figure 5, unloading screw device for the automatic lock suitable for high-voltage tube bus fitting a kind of in the embodiment of the present invention
Operation schematic diagram；The working principle that a kind of automatic lock suitable for high-voltage tube bus fitting unloads screw device is as follows:
When work, whole device is moved to by working position by external equipment first, at this point, high-voltage tube bus to be removed
The panel 51 of 4 fitting 5 is between the nut fixes sleeve 31 and the bolt fixes sleeve 242；Determined by external
Position equipment (vision positionings such as binocular vision or spatial digitizer equipment) will be between nut fixes sleeve and nut to be removed
Positional relationship positioning, all nuts to be removed are stuck in the nut groove of each nut fixes sleeve；
Then, single chip machine controlling circuit controls first motor by driving circuit and rotates clockwise, and drives the lead screw suitable
Hour hands rotation, and then the entire Bolt dismantling component is driven to move preset distance to fitting panel direction along the sliding rail
X (can also pass through external positioning device dynamic measurement moving distance), make bolt fixes sleeve front end and fitting wait tear open
Unloading bolt 52 and being in contact (has multiple bolts 52 to be removed, each bolt to be removed is in fitting panel on a fitting panel
Another side is all corresponding with a nut to be removed)；At this point, single chip machine controlling circuit is inverse by driving circuit the second motor of control
Hour hands rotation, and then drive all bolt fixes sleeves to rotate clockwise simultaneously by the transmission of gear set, while single-chip microcontroller
Control circuit controls first motor by driving circuit and continues to rotate clockwise, with drive the entire Bolt dismantling component along
The sliding rail is mobile to fitting panel direction, and all bolts 52 to be removed are stuck in the bolt indentation of each bolt fixes sleeve
It is interior；
When all bolts 52 to be removed stick into the bolt indentation, the rotating torque of the second motor will increase rapidly
Greatly, when the rotating torque of the second motor feedback received when single chip machine controlling circuit is more than or equal to preset Resistance Value,
It controls the second motor to rotate clockwise, and then drives all bolt fixes sleeves to turn counterclockwise simultaneously by the transmission of gear set
It is dynamic, while first motor stops operating, and is disassembled with being bolted sleeve for bolt 52 to be removed；In the process of disassembly
In, the propulsive thrust for being dismantled separation between bolt 52 to be removed and fitting panel 51 mutually is push edge by entire Bolt dismantling component
Sliding rail is mobile towards fitting panel opposite direction, and until bolt 52 to be removed is detached from fitting panel 51 completely, disassembly is finished.
Due to disassembly during, four bolts to be removed be it is symmetrical, so the torsion generated in disassembly process
It can cancel out each other, not will cause the shaking of device；Torque endurance is analyzed below:
Four bolts are locked simultaneously unload during, can mutually be used as the reversed arm of other side between bolt, counteracting by tightening or
Demounting bolt and the opposing torque generated；
Mechanics Calculation is as follows:
When four bolt fixes sleeves work at the same time, each bolt fixes sleeve can generate one clockwise big
The small countertorque for M, the distance of common center point O of the point of force application of each bolt fixes sleeve apart from all bolt fixes sleeves
For d, force analysis figure is as shown in Figure 6:
Since the fixation of each bolt fixes sleeve is set on bolt to be removed, under the restriction effect of bolt to be removed,
Each bolt fixes sleeve generates a torsion F respectively around each bolt to be removed1, F2, F3And F4, and each torsion is with right
The axle center for the bolt fixes sleeve answered obtains each bolt fixes sleeve by symmetry according to torque M equilibrium equation for rotation center
Force bearing formulae it is as follows:
M1=F1×d
M2=F2×d
M3=F3×d
M4=F4×d
M1=M3
M2=M4
As can be seen from the above equation, the central axis of each bolt fixes sleeve is not influenced completely by countertorque at this time.
The beneficial effects of the present invention are: technical solution proposed by the invention can carry out four bolts on fitting panel
Lock unloads simultaneously, and efficiency is higher, and unloads the torsion between bolt by lock for four during lock unloads and cancel out each other, and locks increasing
It ensure that the stability of device operation process under the premise of unloading torque, while there is magnet in nut side, it is ensured that be removed
Nut is nonvoluntary to be fallen, and is caused safety accident, is improved operating efficiency and operational safety.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
