Description
Technical field
The utility model relates to a kind of rope ladder support, especially relates to a kind of circuit homework automatic blocking rope ladder support.
Background technology
Since 1 or nine the May 4th years were carried out live line working, when on transmission line wire, using soft ladder busywork, the rope ladder support adopts direct hanging type always, the rope ladder support is in and does not have the state that seals in the rope ladder process up and down, after 2005 " State Grid Corporation of China's electric power safety working regulation " revised, when rules require to be used soft ladder busywork, rope ladder head sealed effective sealing in the operation process.Yet at present, domestic rope ladder support needs the operating personnel to carry out manual latch and seals after being hooked on the overhead wire, and after operation finished, the opening of manually pulling pin had again so both increased the danger of personnel's operations, had reduced operating efficiency again, wasted time and energy.The external rope ladder support that does not also have effective closing function.With the effect that realizes that the rope ladder support is in the automatic blocking guard mode all the time, can opens automatically in the entire job process when work finishes dismounting.
The utility model content
The purpose of this utility model is to provide a kind of rope ladder support of can realizing to be in the automatic blocking guard mode all the time in the entire job process, to finish in work and can open automatically when removing, and improves the circuit homework automatic blocking rope ladder support of operational security and operating efficiency.
For achieving the above object, the utility model is by the following technical solutions:
A kind of circuit homework automatic blocking rope ladder support of the present utility model, the rope ladder support that is used to be connected rope ladder that comprises the N type support that is used for the hook hangers ceases to be busy, is connected as a single entity with N type support.2 overhead wire porch at described N type support are provided with automatic sealing device.
Described automatic sealing device is made up of L type closing arm, transmission line stretcher, back-moving spring, drive link, backguy transmission arm, L type closing arm cooperates with N type support hinge, an arm end of L type closing arm is interrupted to contact with the inboard of N type carrier openings arm and cooperates, another arm end of L type closing arm is connected with an end of transmission line stretcher, the other end of transmission line stretcher be located at the backguy transmission arm that L type closing arm below is fixedly connected on the drive link and be connected, the transmission line stretcher is sleeved in the spool that is fixed on the rack rod.The two ends of drive link cooperate with the two stands vertical rod activity of N type support by bearing, and the backguy transmission arm is by being fixed on the position block location on the rack rod.One end of back-moving spring is connected with the backguy transmission arm, and the other end of back-moving spring is connected on the rack rod of backguy transmission arm top; The middle part of drive link is provided with downward-sloping lanyard ring with respect to the opposite side of backguy transmission arm; The bottom of N type support U type support bar is provided with and the corresponding locating ring of lanyard ring.
Above-mentioned circuit homework automatic blocking rope ladder support, the top of 2 rack rods of described N type support is respectively equipped with insulating bar link, P.P's safeguard protection ring, and described rope ladder support is provided with and the fixing jump ring of insulating bar link corresponding insulation bar.
Above-mentioned circuit homework automatic blocking rope ladder support, the horizon bar of described N type support pulley upper end is provided with and is used to control the brake gear that pulley slides; Described brake gear is made up of brake lever, brake shoes, rotary screw, rotary screw and horizon bar threaded engagement, and brake lever is fixedlyed connected with the upper end of rotary screw, and brake shoes places between horizon bar and the pulley and with the lower end of rotary screw fixedlys connected; The section configuration of the shape of described brake shoes and the circumferential recess of pulley is corresponding.
Because the utility model adopts technique scheme, has following beneficial effect:
Adopt automatic sealing device, rope ladder hangs in back, the work and before removing and need not auxiliary operation, can remain the automatic sealing state, prevent the staff work on the rope ladder or in upper and lower rope ladder process because rope ladder lateral force inequality, make the one end hitch point perk of rope ladder support, cause that the rope ladder support comes off from lead, cause staff high-altitude falling accident.When rope ladder hangs and removes, can open sealing easily, be convenient to install and remove, and on the rope ladder support, work or up and down in the process, seal automatic blocking, greatly improve fail safe.Manually seal thereby broken away from can only rely on the staff to climb just to carry out rope ladder to the rope ladder top in the past, before the following rope ladder just the situation of sealing the risk work of opening.
Adopt the hand-operated brake device can make hanging rope ladder and personnel and on the rope ladder support, during operation, prevent that the rope ladder support from sliding convenient working; Employing is provided with link, jump ring on rack rod, fixed insulation bar that can be stable efficiently solves the generation that insulating bar is placed inconvenience and fallen the insulating bar phenomenon.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
