after the heavy object reaches the installation position, the other end of the rope 24 is loosened, the arc-shaped gravity check plate 251 swings downwards under the action of self gravity, and the first check latch teeth 2511 and the second check latch teeth 2521 engage the rope 24 instantly to achieve the purpose of locking the rope 24;
the blocking plate 253 is rotated and slides towards the direction far away from the arc-shaped gravity check plate 251, after the blocking opening 2532 is aligned with the blocking plate clamping column 27, the blocking plate 253 is pushed towards the arc-shaped gravity check plate 251, the blocking opening 2532 is sleeved on the blocking plate clamping column 27, the blocking nut 28 is screwed, and the side blocking of the rope 24 is completed.
D, after the heavy object is unloaded, loosening the baffle nut 28, pushing the baffle 253 to enable the clamping opening 2532 to leave the baffle clamping column 27, pulling the unlocking wrench 2512 to enable the arc-shaped gravity check plate 251 to swing upwards and to be away from the rope clamping plate 252, enabling the rope to slide freely in the rope channel, enabling the rope 24 to pass through one end of the rope channel to fall to the bottom surface, and continuing the tying operation;
and e, after the construction is finished, detaching the rope self-locking pulley 2 from the chain link type self-locking fixture 1, and unlocking the chain link type self-locking fixture 1 from the electric wire rod 9.
From the above, the overhead hoist for operation on the outside wire electrical pole provided by the invention has the following beneficial effects:
the invention provides an operation lifting device on an outside electrician pole, which can be fixedly hung on a telegraph pole to match outside electricians to perform construction operation on the pole, and can finish lifting of materials and equipment.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention.
