Description
Technical field
This utility model relates to a kind of tightener for stringing.
Background technology
Tightener, is again ratchet tightener, uses as tension wire in overhead transmission line cable laying operation.First the steel wire rope on tightener or galvanized iron wire are unclamped during use, and be fixed on cross-arm, clamp wire with clamping pliers, then pull special wrench.Due to the anti-reverse effect of ratchet, gradually steel wire rope or galvanized iron wire are wound on ratchet roller, make wire tighten up.The wire tightened up is fixed on the insulator.The most first unclamp ratchet, make steel wire rope or galvanized iron wire unclamp, then unclamp clamping pliers, finally steel wire rope or galvanized iron wire are wound on the cylinder of ratchet.Tightener application: the plant equipment of the infrastructural projects such as building, highway, bridge, metallurgy, mine, side slope tunnel, hoistway improvement protection.
Tightener classification has: tiger head tightener, bent tooth tightener, iron wire tightener, double-hook wire grip, Multifunctional tightener, triangle tightener and Japanese tension disk.Multifunctional tightener: it includes clamp part and stringing part, is characterized in that its stringing part, on axis in addition to equipped with a ratchet, is also equipped with a gear wheel and the commutation hook engaged with gear wheel.Tiger head tightener: tighten up steel strand wires iron wire for transmission line of electricity, communication line.First the steel wire rope on tightener or galvanized iron wire are unclamped when tightener uses, and be fixed on cross-arm, clamp wire with clamping pliers, then pull special wrench.
Inconvenience installed by current existing tightener when high-altitude stringing, and stringing effect is bad, and during operation, rocking arm can only rotate toward a direction, it is impossible to enough toward revolution, in-convenience in use.
Utility model content
It is effective that the technical problems to be solved in the utility model is to provide a kind of stringing, easy to adjust, and leicht fallen D/A during use can not result in, with rollback rocking arm, the tightener for stringing that electric wire unclamps.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of tightener for stringing, including mobile jib, holding part, pulley and rocking arm, the concave setting in described holding part two ends, described mobile jib is hinged with holding part, fixing screw it is provided with on described mobile jib, described pulley is located in holding part, described pulley is flexibly connected with holding part, described rocking arm is located at holding part side, described rocking arm front end is provided with U-shaped part, it is provided with the first ratchet mechanism in described U-shaped part, described holding part opposite side is provided with the second ratchet mechanism, described pulley is in transmission connection with the first ratchet mechanism and the second ratchet mechanism respectively.
As preferably, described U-shaped part welds with rocking arm.
As preferably, described pulley middle part surface camber is arranged.
As preferably, described rocking arm is provided with through hole.
As preferably, described fixing screw length is more than 6cm.
The beneficial effects of the utility model are: the mobile jib of setting is arranged on cross-arm by regulation screw, keep to produce movement when using, easy to operate；The second ratchet mechanism arranged is prevented from pulley and reverses during the tensioning of electric wire, leicht fallen D/A when keeping using；The first ratchet mechanism arranged makes rocking arm can will not drive pulley rotation with rollback, does not results in electric wire and unclamps, keeps easy to adjust.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of tightener for stringing of this utility model.
Detailed description of the invention
As shown in Figure 1, a kind of tightener for stringing, including mobile jib 1, holding part 2, pulley 3 and Rocker arm 4, the concave setting in described holding part 2 two ends, described mobile jib 1 is hinged with holding part 2, fixing screw 5 it is provided with on described mobile jib 1, described pulley 3 is located in holding part 2, described pulley 3 is flexibly connected with holding part 2, described Rocker arm 4 is located at holding part 2 side, described Rocker arm 4 front end is provided with U-shaped part 6, the first ratchet mechanism 7 it is provided with in described U-shaped part 6, described holding part 2 opposite side is provided with the second ratchet mechanism 8, described pulley 3 is in transmission connection with the first ratchet mechanism 7 and the second ratchet mechanism 8 respectively.
Described U-shaped part 6 welds with Rocker arm 4, keeps U-shaped part Stability Analysis of Structures reliable.
Described pulley 3 middle part surface camber is arranged, and facilitates electric wire to be arranged on pulley 3.
It is provided with through hole 9 on described Rocker arm 4, by through hole 9, tightener cannot be hung not using.
Described fixing screw 5 length is more than 6cm, is conveniently fixed on cross-arm by mobile jib 1 in use.
The beneficial effects of the utility model are: the mobile jib of setting is arranged on cross-arm by regulation screw, keep to produce movement when using, easy to operate；The second ratchet mechanism arranged is prevented from pulley and reverses during the tensioning of electric wire, leicht fallen D/A when keeping using；The first ratchet mechanism arranged makes rocking arm can will not drive pulley rotation with rollback, does not results in electric wire and unclamps, keeps easy to adjust.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
