Abstract
The utility model discloses an internally piloting formula auto -lock ladder head, including left pole setting (8) and right pole setting (9), left side pole setting (8) and right pole setting (9) top -down are provided with pulley (1) in pairs, the buckle, coaster hanging hole (3) and bottom hanging hole (10), connect left pole setting (8) respectively for both ends between coaster hanging hole (3) and bottom hanging hole (10), carriage release lever (6) and dead lever (7) of the right side pole setting (9), be connected with rope couple (5) on carriage release lever (6), be provided with auto -lock locking plate (2) on coaster hanging hole (3), auto -lock locking plate (2) are terminal articulated with transfer line (4), transfer line (4) are terminal to link to each other with carriage release lever (6), connect through spring (11) between carriage release lever (6) and dead lever (7). The utility model provides a during the rope ladder unable automatic insurable problem of closing and opening that realizes of ladder head about among the live working, reduced the operating risk, optimized operation procedure, operation personnel's safety has been protected to whole journey.
Description
Technical field
The utility model relates to a kind of live line working device, changes insulator, repairs the hanging ladder ladder head of lead wire and earth wire etc. especially for hot line maintenance medium potential.
Background technology
In Equipotential live working; it is one of operational method commonly used in live line working that operating personnel enters equipotential by climbing rope ladder; during operation; need first wire to be linked into terraced head opening; after terraced head suspension is good; after equal potential working personnel enter equipotential, (when operating personnel climbs up terraced head) can manual-lock safeties; this operating process (closedown safeties) cannot realize in the upper and lower rope ladder process of operating personnel; cause climbing operating personnel safeguard protection inadequate, easily occur the danger of accidental falling.In view of the foregoing, be necessary to design a device, effectively overcome above technical problem.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of internal control type self-locking ladder head; operating personnel climbs in the whole process of operation industry and realizes opening and closing automatically of terraced head opening; improve operational security and reliability, omnidistance available protecting operating personnel safety.
The technical solution of the utility model is: a kind of internal control type self-locking ladder head, comprise left vertical rod and right vertical rod, left vertical rod and right vertical rod are provided with pulley from top to bottom in pairs, buckle, coaster hanging hole and bottom hanging hole, for two ends respectively connected left vertical rod, the carriage release lever of right vertical rod and fixed lever between coaster hanging hole and bottom hanging hole, carriage release lever is connected with hanger with rope, coaster hanging hole is provided with self-locking locking plate, self-locking locking plate end and drive link hinged, drive link end is connected with carriage release lever, connects between carriage release lever and fixed lever through spring.
Described self-locking locking plate is flexibly connected by the inner face of connecting bolt with coaster hanging hole, and the end of self-locking locking plate and drive link hinged through rivet.Self-locking locking plate can rotate around the inner face of coaster hanging hole, and the sweep on self-locking locking plate top can block the buckle in vertical rod, realizes self-locking safety.The end of self-locking locking plate and drive link interact, and are moved up and down thus the rotation of self-locking locking plate of practising by drive link.
Described left vertical rod and right vertical rod are hollow pipe, and spring is positioned at pipe, and spring is positioned to manage avoids vertical rod periphery to occur unnecessary component on the one hand, produces unnecessary contact danger, another aspect also better appearance.
Buckle is as the frame member coordinated with self-locking locking plate, and it is arranged on left and right rod end usually, for the pulley yoke of fixed block, also can consider to be arranged on separately in the vertical rod of left and right.
The utility model is by the hollow vertical rod of terraced head self, two springs are respectively loaded onto in bar, lower spring end is fixed on the fixed lever two ends of terraced head, upper end is fixed on carriage release lever two ends, carriage release lever is connected with hanger with rope and drive link, drive link is hinged with self-locking locking plate on the end face of coaster hanging hole, forms connecting rod.When tying up to rope on hanger with rope and upwards play hanging ladder head and rope ladder, due to the self gravitation effect of object, by the spring in the vertical rod of stretching left and right, drive carriage release lever upward sliding, thus drive link is pushed upwardly, now drive link heads on the end of self-locking locking plate, causes self-locking locking plate to rotate, depart from buckle, thus open self-locking safety device.
When rope ladder and terraced head hang over after on wire, hanger with rope is no longer stressed, and under spring force, pull carriage release lever to move down, drive link also moves down, and drives self-locking locking plate to rotate and blocks buckle, thus close terraced head opening, reach the object of self-lock protection.
Meanwhile, the utility model respectively establishes two coaster hanging holes on terraced head both sides, hangs coaster when being convenient to install personal safety protector and operation.
Compared with the prior art, when can solve upper and lower rope ladder in live line working, ladder head cannot realize insuring the problem of closing and opening the utility model automatically, reduces operating risk, optimizes work flow, the whole process protection safety of operating personnel.

Embodiment
As shown in Fig. 1 ~ Fig. 7, a kind of internal control type self-locking ladder head, comprise left vertical rod 8 and right vertical rod 9, left vertical rod 8 and right vertical rod 9 are provided with pulley 1 from top to bottom in pairs, buckle, coaster hanging hole 3 and bottom hanging hole 10, for two ends respectively connected left vertical rod 8, the carriage release lever 6 of right vertical rod 9 and fixed lever 7 between coaster hanging hole 3 and bottom hanging hole 10, carriage release lever 6 is connected with hanger with rope 5, coaster hanging hole 3 is provided with self-locking locking plate 2, self-locking locking plate 2 end and drive link 4 hinged, drive link 4 end is connected with carriage release lever 6, connects between carriage release lever 6 and fixed lever 7 through spring 11.Self-locking locking plate 2 is flexibly connected with the inner face of coaster hanging hole 3 by connecting bolt 12, and the end of self-locking locking plate 2 and drive link 4 hinged through rivet 13.Left vertical rod 8 and right vertical rod 9 are hollow pipe, and spring 11 is positioned at pipe.Buckle, as the frame member coordinated with self-locking locking plate 2, is arranged on left and right rod end, for the pulley yoke of fixed block 1.
During use, rope ladder is hung on terraced head bottom hanging hole 10, fasten at hanger with rope 5 with the rope that height is aerial, then by personal safety protector rope bolt in coaster hanging hole 3; Pull rope, terraced head is hung lead location, rotate rope ladder, hang on wire by terraced head, unclamp rope, self-locking locking plate 2 blocks the buckle of terraced head opening automatically.After equipotential personnel have fastened autoprotection, enter equipotential along rope ladder.During dismounting, treat that pull rope, self-locking is opened to ground under equipotential personnel, rotate rope ladder, rope ladder and terraced head are put to ground.This device should be noted following main points when using:
Prevent rope from mutually beating strand when 1, using, avoid affecting equal potential working human users;
2, should direction be had an optimistic view of when rotating rope ladder, rotating, during taking-up also roughly the same;
