Description
Technical field
The utility model relates to a kind of automatic sealing somersault coaster.
Background technology
When on transmission line, using soft ladder busywork, all need to realize articulating and removing between rope ladder and the lead by special use somersault coaster.Increasing along with a large amount of rope ladder work such as inter-phase spacer installation in recent years, the application of somersault coaster on transmission line is increased.Because existing somersault coaster does not possess enclosing function, comes off easily in operation process, bring many unsafe factors, and increased the workload that repeats to install, reduce efficiency.How better to solve the problem that in somersault coaster suspension process, comes off, become the problem that the power transmission lines overhauling worker must face.
The utility model content
The purpose of this utility model provides a kind of can overall process sealing in operation process, the coaster of having avoided tumbling in the operation process comes off, and influences the automatic sealing somersault coaster of job safety and operating efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic sealing somersault coaster, and load hook below is connected with fixed pulley, and described load hook is " for a long time " font; The openend of load hook is provided with and seals arm-tie, seals arm-tie and is provided with and is used to seal the up and down switching adjustment hole of arm-tie, seals arm-tie by opening and closing adjustment hole and being located at load and linking up with 2 positive stops on the openend arm and slide up and down and cooperate; Seal to be provided with between the top of arm-tie and the positive stop and be used to seal the self-sealing extension spring of arm-tie; The top of load hook is provided with the direction control ring near a side of support arm, and the lower end of sealing arm-tie is provided with the lanyard ring.
Above-mentioned automatic sealing somersault coaster, the described arm-tie upper end of sealing is provided with and is used for manually drawing back the draw ring that seals arm-tie.
Above-mentioned automatic sealing somersault coaster, the backplate of described fixed pulley is shaped as hexagon.
The beneficial effects of the utility model are: adopt " for a long time " font load hook, the somersault coaster is hung on the lead easily.
Adopt the openend of load hook to be provided with and seal arm-tie, seal arm-tie by opening and closing adjustment hole and being located at load and linking up with 2 positive stops on the openend arm and slide up and down and cooperate; Seal to be provided with between the top of arm-tie and the positive stop and be used to seal the self-sealing extension spring of arm-tie; The top of load hook is provided with the direction control ring near a side of support arm, and the lower end of sealing arm-tie is provided with the lanyard ring.The rope of colligation be can utilize, lifting, gradient control, hanging wire and the dismounting of somersault coaster realized in the lower end of sealing arm-tie; By the cooperation of rope and extension spring, realize the automatic blocking that the somersault coaster seals and open;
Employing is sealed arm-tie upper end and is provided with draw ring, during operation, only needs provoke draw ring with action bars near the shaft tower body, and installation and the dismounting of coaster on lead can realize tumbling.
Adopt hexagon pulley backplate can reduce the frictional force of rope to greatest extent.
The use that the utility model has solved the somersault coaster is in the difficult problem of unprotect state for a long time, avoids the suspension process to suffer the somersault coaster and comes off, for the operation field that uses the somersault coaster provides safety guarantee.Realized that the sliding whole process of somersault is sealed in the operation process, improved operational security and operating efficiency.The inter-phase spacer that can be widely used in transmission line is installed, stockbridge damper is installed, power failure is repaired in lead, charged repairing lead and the equal potential working.
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.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Embodiment
As Fig. 1, shown in Figure 2, a kind of automatic sealing somersault coaster, load is linked up with 5 belows and is connected with fixed pulley 8, described load hook is " for a long time " font, the openend of load hook is provided with and seals arm-tie 3, sealing arm-tie is provided with and is used to seal the up and down switching adjustment hole 9 of arm-tie, seal arm-tie by opening and closing adjustment hole and being located at load and linking up with 2 positive stops 4 on the openend arm and slide up and down and cooperate, seal to be provided with between the top of arm-tie and the positive stop and be used to seal the self-sealing extension spring 2 of arm-tie, the top of load hook is provided with direction control ring 6 near a side of support arm, and the lower end of sealing arm-tie is provided with lanyard ring 7.
Sealing arm-tie upper end is provided with and is used for manually drawing back the draw ring 1 that seals arm-tie.During operation, only need provoke draw ring with action bars near the shaft tower body, installation and the dismounting of coaster on lead can realize tumbling.The backplate of fixed pulley 8 is shaped as hexagon.
As shown in Figure 3: during use, the ground handling personnel earlier threw lead 10 with rope, rope one end were passed the lanyard ring 7 that seals arm-tie 3 lower ends, direction control ring 6 and sagging naturally, and rope and lanyard ring 7 tying-ups are fixed; The pulling rope promotes end 11, seal arm-tie 3 just under action of gravity, by opening and closing upwards slip and spacing of adjustment hole 9 through positive stop 4, extension spring 2 stretches, when the somersault coaster is promoted to lead 10 positions, spur rope direction control end 12 simultaneously, make the somersault coaster be skewed, light tow promotes end 11, the type load hook 5 of somersault coaster " for a long time " word just is suspended on the lead 10 automatically, and payout promotes end 11 and rope direction control end 12, makes the somersault coaster be nature and hangs vertical configuration, seal arm-tie 3 and under the effect of extension spring 2, reset, be i.e. automatic sealing.Utilize the fixed pulley 8 of below, carry out the suspension and the dismounting of operation rope ladder support.
Method for dismounting is opposite with installation method, promptly spur rope direction control end 12 earlier, make the somersault coaster be skewed, sealing arm-tie 3 upwards slides under the effect of rope pull, make to seal and open, light tow promotes end 11, after the somersault coaster breaks away from lead 10, payout promotes end 11 simultaneously, makes the somersault coaster fall to getting final product naturally from lead 10.
If during operation, only need provoke draw ring 1 with action bars near the shaft tower body, the installation and removal of coaster on lead 10 can realize tumbling.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
