34 can drive the regulating rod 35 to leave the winding roll 21, since second iron hoop 43 can be adsorbed by the magnetite 37, because
This, the regulating rod 35 can drive the engagement plate 41 to be touched, and the rubber wheel 42 leaves the volume with the steel ball 36
Drum 21, and the cable 22 is wound on the winding roll 21；
During for electrical plug, some is selected for after electric installation, being powered to corresponding coil 32, the coil 32 can make institute after being powered
It states iron axis 31 to generate magnetism and adsorb first iron hoop 33 towards the direction of the iron axis 31, so as to drive the trolley shoe 34
It is slided towards the direction of the baffle 14, since the engagement plate 41 and the Coupling Shaft 19 can axially slip, institute
Stating trolley shoe 34 can drive the regulating rod 35, engagement plate 41 and the rubber wheel 42 to be slided towards the direction of the winding roll 21
It is dynamic, after the rubber wheel 42 clamps winding roll 21, remove the plug board 23 and start the electricity favourable turn 18, the electricity
Favourable turn 18 can drive the Coupling Shaft 19 to rotate, and be fixed since the engagement plate 41 is circumferential with the Coupling Shaft 19
, therefore, the Coupling Shaft 19 can drive the engagement plate 41, rubber wheel 42 to be rotated with the winding roll 21 and to the electricity
Cable 22 carries out payoff operation, after the cable 22 is adjusted to appropriate length, stops the electricity favourable turn 18, is simultaneously stopped to described
The energization of coil 32, at this point, using the plug board 23 and the plug grafting of electrified maintained equipment, so as to complete for being electrically connected
It connects, at the same time, the trolley shoe 34 is biased in the spring element 38 towards the direction for leaving the baffle 14, the trolley shoe
It slides in 34 directions that the regulating rod 35, engagement plate 41 and the rubber wheel 42 can be driven to leave the winding roll 21；
After power supply, the plug board 23 and the plug of electrified maintained equipment are pulled away first, then by the coil 32
It being powered, the coil 32 can make the iron axis 31 generate magnetism and be adsorbed described 33 towards the direction of the iron axis 31 after being powered,
So as to which the regulating rod 35, engagement plate 41 and the rubber wheel 42 be driven to be slided towards the direction of the winding roll 21, work as institute
It states after rubber wheel 42 clamps the winding roll 21, starts the electricity favourable turn 18, the electricity favourable turn 18 can drive the Coupling Shaft 19
It rotates backward, the Coupling Shaft 19 can drive engagement plate 41, the rubber wheel 42 to be rotated backward with the winding roll 21 and right
The cable 22 carries out take-up operation, after the cable 22 recycles in place, stops the electricity favourable turn 18, is simultaneously stopped to described
The energization of coil 32, at this point, the plug board 23 is suspended in the clamping frame 17, and the trolley shoe 34 is in the elastic force
Part 38 by towards leave the baffle 14 direction bias, the trolley shoe 34 can drive the regulating rod 35, engagement plate 41 with
And the rubber wheel 42 leaves the direction slip of the winding roll 21.
The beneficial effects of the invention are as follows：In original state, coil is not powered on apparatus of the present invention, and trolley shoe is in spring element
The direction bias of baffle is left under effect, trolley shoe can drive regulating rod to leave winding roll, since the second iron hoop can be by magnetite
Absorption, regulating rod can drive engagement plate to be touched with steel ball, and rubber wheel leaves winding roll, therefore, in some non-selected confession
During electric installation, electricity favourable turn can not drive winding roll to carry out unwrapping wire；
When needing to power to electrified maintained equipment, some is selected for after electric installation, being powered to corresponding coil, coil leads to
Iron axis can be made to generate magnetic after electricity and adsorb the first iron hoop towards the direction of iron axis, so as to which trolley shoe be driven to be slided towards the direction of baffle
It is dynamic, since engagement plate and Coupling Shaft can axially slip, trolley shoe can drive regulating rod, engagement plate and rubber
Rubber tire is slided towards the direction of winding roll, after rubber wheel clamps winding roll, is removed plug board and is started electric favourable turn, and electricity favourable turn can band
Turn spindle rotates, and due to engagement plate with Coupling Shaft be circumferentially it is fixed, Coupling Shaft can drive engagement disk
Plate, rubber wheel are rotated with winding roll and carry out payoff operation to cable, after cable is adjusted to appropriate length, stop electricity favourable turn,
The energization to coil is simultaneously stopped, at this point, using the plug board and the plug grafting of electrified maintained equipment, so as to complete to supply
Electrical connection, at the same time, for trolley shoe in spring element by towards the direction bias for leaving baffle, trolley shoe can drive regulating rod, engagement
It slides in the direction that plate and rubber wheel leave winding roll；
After power supply, the plug board and the plug of electrified maintained equipment are pulled away first, then coil is powered, coil
Iron axis can be made to generate magnetic after energization and will be adsorbed towards the direction of iron axis, so as to drive regulating rod, engagement plate and rubber wheel
It is slided towards the direction of winding roll, after rubber wheel clamps winding roll, starts electricity favourable turn, electricity favourable turn can drive Coupling Shaft reversely to turn
Dynamic, Coupling Shaft can drive engagement plate, rubber wheel to be rotated backward with winding roll and carry out take-up operation to cable, when cable recycles
After in place, stop electricity favourable turn, be simultaneously stopped the energization to coil, at this point, plug board is suspended in clamping frame, and trolley shoe exists
For spring element by towards the direction bias for leaving baffle, trolley shoe can drive regulating rod, engagement plate and rubber wheel to leave winding roll
Direction slide；
Apparatus of the present invention will not interfere other to supply Denso after some is selected for electric installation during take-up and unwrapping wire is carried out
It puts, and cable length can arbitrarily be adjusted according to use demand, therefore, different distance can be met and multigroup electrified safeguard sets
Standby connection requirement of powering simultaneously, and cable can be retracted into described matrix after use, thus prevent cable skin long
Time is exposed extraneous and cause to be damaged, and greatly improves service life.
The above, the specific embodiment only invented, but invent protection domain be not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should all be covered within the protection domain of invention.Therefore, the protection domain of invention
It should be determined by the scope of protection defined in the claims.
