Car reaches job position on shaft tower, pulls link 1, and the U-shaped chute 7 sealed up a door on one 5 slides along wire guide pulley wheels drift bolt 6, seals up a door
1 in chute 18 of sealing up a door upward sliding, sealing up a door one 5 fully opens.Staff is tangled with the hook of insulating bar front end
Annulus on link 1, insulating bar guiding line direction is enumerated, and makes the opening of slip-off preventing circulating transfer coaster be directed at wire,
Wire slides on wire guide pulley wheels 4 along conductor slide plate 8, and staff pushes insulating bar, pushes mechanical compliance and insulating bar
Be delivered on link 1, seal up a door 1 in chute 18 of sealing up a door slide downward, blocking magnet 10 enters into the U-shaped insertion of apparatus for suspension base
In groove 16, contact with locking iron plate 12, one 5 closings of sealing up a door.Wire guide pulley wheels 4 can roll on wire, in circulating transfer rope
Pull operating position on lower arrival wire.
After slip-off preventing circulating transfer coaster installation, crossbeam in the rope ladder head with self-locking device for the surface personnel
One personnel protection rope with coaster of 30 side mounting, and untie slip-off preventing circulating transfer supratrochlear circulating transfer rope and connect
Head, one end small slide of circulating transfer rope is hooked in enhancing ring 29, pulls the other end of circulating transfer rope, and rope ladder is raised
Rise, when the rope ladder head with self-locking device will be close to lead location, surface personnel rotates rope ladder, makes on rope ladder head
Front coupling beam 21 and rear coupling beam 102 avoid with wire, and make the opening that wire is located between rear main support 28 and rear assistant support 101
Side.Surface personnel continues to lift up rope ladder, so that the opening between rear main support 28 and rear assistant support 101 is slightly above wire and turn
Ease back ladder.Surface personnel's relaxation cycle transmission rope, wire enters into the opening between rear main support 28 and rear assistant support 101
Interior, when conductive contact is to during from bolt plate 26, will back down from bolt plate, enter within bolt plate.Wire is completely into arriving
After from bolt plate, set back in the presence of hyoplastron case spring elastic force from bolt plate, by rear main support 28 and rear pair
Closure of openings between support 101.Surface personnel continues relaxation cycle transmission rope, after walk line wheel 103 and drop on wire,
Rope ladder head installation with self-locking device.
After rope ladder head installation with self-locking device, surface personnel will be arranged in the rope ladder head with self-locking device
Crossbeam 30 on personnel protection rope one end system hang over climbing rope ladder personal security band rear braces on, personnel protection rope another
End penetrates in the left draw-in groove 53 climbing rope ladder person catching device, bypasses pulley 48, passes in right draw-in groove 52.Then, press
Lower spring hyoplastron 44, will hang on the sling being fixed at column foot, trip spring hyoplastron 44, hook closure sealing.When climbing
Step on soft ladder busywork personnel along rope ladder climb upwards when, the personnel protection rope that passes from right draw-in groove of staff's tension, the person under tower
Protection rope, in the presence of pulling force, slides along left draw-in groove 53, pulley 48, right draw-in groove 52.Personnel protection rope slide when and clamp
The frictional force that 50 both sides contact surfaces produce, drives clamp 50 to rotate clockwise, and makes left draw-in groove 53 and right draw-in groove 52 draw-in groove become big, rope
Rope passes through.When climb rope ladder personnel climbing during happen suddenly accidental falling when, human bady gravitational drive rope along wear to
Adverse movement, clamp 50 rotates counterclockwise in the presence of safety pin spring 58 immediately, so that left draw-in groove 53 and right draw-in groove 52 draw-in groove is become
Little, the left and right arcuation projection of clamp 50 rapidly by stuck for rope in left draw-in groove 53 and right draw-in groove 52, personnel protection rope is no longer sliding
Dynamic, personnel are hung not in tenesmus by personnel protection rope.
Climb rope ladder staff after service work terminates on wire, the rope ladder along in the rope ladder head with self-locking device returns
When going back to ground, control the surface personnel climbing rope ladder person catching device, the right draw-in groove in the main link plate of right hand palm when held 45 right side
52 positions, thumb pulls column spinner 54 clockwise, makes left draw-in groove 53 and right draw-in groove 52 draw-in groove become big, left hand helps personnel protection
Rope, personnel protection rope, with the decline of climbing rope ladder personnel, slides counterclockwise along right draw-in groove 52, pulley 48, left draw-in groove 53, when
Climbing rope ladder personnel happen suddenly during lower rope ladder accidental falling when, control the personnel climbing the personal catching device of rope ladder loose rapidly
Open column spinner, clamp 50, in the effect rotate counterclockwise immediately of safety pin spring 58, makes left draw-in groove 53 and right draw-in groove 52 draw-in groove diminish,
The left and right arcuation projection of clamp 50 rapidly by stuck for personnel protection rope in left draw-in groove 53 and right draw-in groove 52, personnel protection rope is no longer
Slide, personnel are hung by personnel protection rope and no longer drop.
Climb rope ladder staff down to after ground, on shaft tower, staff is caught on the crotch of insulating bar front end and draws
Ring 25, pushes insulating bar, from bolt plate 26 under bolt plate drawstring 32 pulling force effect, with from bolt plate drift bolt 27 as axle
Rotate to from bolt plate dop 24, when touching steel ball 35 from bolt plate 26 top steel plate, common spring 36 is shunk, steel ball
It is retracted to from bolt plate dop 24.Slip over after steel ball 35 from bolt plate 26 top steel plate, steel ball 35 is in the bullet of common spring 36
Stretch out under power effect, on shaft tower, staff lifts insulating bar, so that the crotch of insulating bar front end and draw ring 25 is disengaged,
Blocked from bolt plate 26 top steel plate by steel ball 35, the opening between main support and assistant support is opened.Surface personnel pulls
Circulating transfer rope, rope ladder rises, and rotates rope ladder, deviates from, relaxation cycle at wire opening between rear main support and rear assistant support
Transmission rope, rope ladder is fallen to ground.
Rope ladder head with self-locking device falls to behind ground, the small slide that surface personnel unsnaps in enhancing ring 29, will
Two terminations of circulating transfer rope are connected together, and on tower, staff tangles link 1 with insulating bar, provokes extension upwards
Ring, blocking magnet 10 is separated with locking iron plate 12 in the presence of pulling force, seals up a door and one 5 opens.Mobile insulating bar makes wire
Go out to skid off from apparatus for suspension 9 right openings along conductor slide plate 8, withdraw slip-off preventing circulating transfer coaster, carry lower tower, return to ground,
Service work completes.
Operating personnel passes through slip-off preventing circulating transfer coaster, the rope ladder head with self-locking device and climbs rope ladder person catching device
Be applied in combination, safety, smoothly complete service work.
