During use, first insulation is transmitted the endless rope pulley 11 of one end through slip-off preventing circulating transfer coaster of rope, then two terminations of transmitting rope of insulating are linked together, form circulating transfer rope.Operating personnel carries slip-off preventing circulating transfer coaster and arrives job position on shaft tower, pulls link 1, and the U-shaped chute 7 of sealing up a door on one 5 slides along wire guide pulley wheels drift bolt 6, seals up a door 1 at upward sliding in chute 18 of sealing up a door, and seals up a door one 5 to open completely.Staff tangles the annulus on link 1 with the hook of insulating bar front end, insulating bar guiding line direction is enumerated, the opening of slip-off preventing circulating transfer coaster is made to aim at wire, wire slides on wire guide pulley wheels 4 along conductor slide plate 8, staff presses down insulating bar, downforce is delivered on link 1 along insulating bar, seal up a door 1 in slide downward in chute 18 of sealing up a door, blocking magnet 10 enters in the U-shaped through slot 16 of apparatus for suspension base, contact with locking iron plate 12, seal up a door 1 close.Wire guide pulley wheels 4 can roll on wire, service position on arrival wire under the pulling of circulating transfer rope.
After the installation of slip-off preventing circulating transfer coaster, the personnel protection rope of an one side mounting band coaster of the crossbeam 30 of surface personnel in the rope ladder head of band self-locking device, and untie the supratrochlear circulating transfer rope socket of slip-off preventing circulating transfer, one end small slide of circulating transfer rope is hooked in enhancing ring 29, pull the other end of circulating transfer rope, rope ladder is raised rising, when being with the rope ladder head of self-locking device to be about to be close to lead location, surface personnel rotates rope ladder, front coupling beam 21 on rope ladder head and rear coupling beam 102 are avoided with wire, and make the open side of wire between rear main support 28 and rear assistant support 101.Surface personnel continues to promote rope ladder, makes the opening between rear main support 28 and rear assistant support 101 a little more than wire and goes back to rope ladder.Surface personnel's relaxation cycle transmission rope, wire enters in the opening between rear main support 28 and rear assistant support 101, when conductive contact is to during from bolt plate 26, will backs down, and enter within bolt plate from bolt plate.Wire enters into after in bolt plate completely, sets back under the effect of hyoplastron case spring elastic force from bolt plate, by the closure of openings between rear main support 28 and rear assistant support 101.Surface personnel continues relaxation cycle transmission rope, and rear cabling wheel 103 drops on wire, the rope ladder head installation of band self-locking device.
After the rope ladder head installation of self-locking device; one end system of personnel protection rope on the crossbeam 30 be arranged in the rope ladder head of band self-locking device hangs on the rear braces of climbing rope ladder personal security band by surface personnel; the other end of personnel protection rope penetrates in the left draw-in groove 53 climbed rope ladder person catching device; walk around pulley 48, pass in right draw-in groove 52.Then, dead spring hyoplastron 44, by hang over be fixed on column foot place sling on, trip spring hyoplastron 44, the closed sealing of hook.When climbing soft ladder busywork personnel and upwards climbing along rope ladder, under tower, staff strains the personnel protection rope passed from right draw-in groove, and personnel protection rope, under the effect of pulling force, slides along left draw-in groove 53, pulley 48, right draw-in groove 52.The frictional force produced with clamp 50 both sides contact-making surface when personnel protection rope slides, drives clamp 50 to rotate clockwise, and make left draw-in groove 53 and the change of right draw-in groove 52 draw-in groove greatly, rope passes through smoothly.When climbing rope ladder personnel happen suddenly accidental falling in the process of climbing; human bady gravitational drives rope to run back along wearing; clamp 50 rotates counterclockwise immediately under the effect of safety pin spring 58; left draw-in groove 53 and right draw-in groove 52 draw-in groove are diminished; 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 no longer slides, and personnel are hung not in tenesmus by personnel protection rope.
After climbing rope ladder staff service work terminating on wire, when returning to ground along the rope ladder in the rope ladder head of band self-locking device, control the surface personnel climbing rope ladder person catching device, right draw-in groove 52 position on the right side of the main link plate of right hand palm when held 45, thumb pulls column spinner 54 clockwise, left draw-in groove 53 and right draw-in groove 52 draw-in groove is made to become large, left hand helps personnel protection rope, personnel protection rope is along with the decline of climbing rope ladder personnel, along right draw-in groove 52, pulley 48, left draw-in groove 53 slides counterclockwise, when climbing rope ladder personnel happen suddenly accidental falling in the process of lower rope ladder, the personnel controlling to climb rope ladder person catching device unclamp column spinner rapidly, clamp 50 is rotated counterclockwise immediately in the effect of safety pin spring 58, left draw-in groove 53 and right draw-in groove 52 draw-in groove are diminished, the left and right arcuation projection of clamp 50 rapidly by personnel protection wire clips extremely in left draw-in groove 53 and right draw-in groove 52, personnel protection rope no longer slides, personnel are hung by personnel protection rope and no longer drop.
Climb rope ladder staff behind ground, on shaft tower, staff catches on draw ring 25 with the crotch of insulating bar front end, press down insulating bar, from bolt plate 26 under the effect of bolt plate stay cord 32 pulling force, from bolt plate drift bolt 27 to be the rotation of axial self-locking hyoplastron dop 24 place, when touching steel ball 35 from bolt plate 26 top steel plate, common spring 36 shrinks, and steel ball is retracted in bolt plate dop 24.After bolt plate 26 top steel plate slips over steel ball 35, steel ball 35 stretches out under the elastic force effect of common spring 36, on shaft tower, staff lifts insulating bar, the crotch of insulating bar front end and draw ring 25 are thrown off, from bolt plate 26 top, steel plate is blocked by steel ball 35, and the opening between main support and assistant support is opened.Surface personnel pulls circulating transfer rope, and rope ladder rises, and rotate rope ladder, wire is deviate from from opening part between rear main support and rear assistant support, and relaxation cycle transmission rope, falls to ground by rope ladder.
After rope ladder head with self-locking device falls to ground, surface personnel unsnaps the small slide in enhancing ring 29, two of circulating transfer rope terminations are connected together, on tower, staff tangles link 1 with insulating bar, upwards provoke link, blocking magnet 10 is separated with locking iron plate 12 under the effect of pulling force, seals up a door one 5 to open.Mobile insulating bar makes wire go out to skid off along conductor slide plate 8 from apparatus for suspension 9 right openings, and regain slip-off preventing circulating transfer coaster, carry lower tower, return to ground, service work completes.
Operating personnel, by slip-off preventing circulating transfer coaster, the rope ladder head of band self-locking device and combinationally using of climbing rope ladder person catching device, safely, completes service work smoothly.
