Description

Power line construction cord holder

Technical field

The utility model relates to a kind of power line construction cord holders, belong to technical field of electric power construction.

Background technique

Cord holder is also referred to as ratchet tightener, is to be used as to further used in conducting wire in overhead transmission line laying construction.Make Used time, first wirerope or galvanized iron wire on cord holder unclamped, and was fixed on cross-arm, clamps conducting wire with clamping pliers, then pulls Dynamic special spanner.Since the anti-reverse of pawl acts on, gradually wirerope or galvanized iron wire are wound on ratchet roller, receive conducting wire Tightly.Conducting wire tightening is fixed on the insulator.Then pawl is first unclamped, wirerope or galvanized iron wire is unclamped, unclamps again folder Line tweezer is finally wound on wirerope or galvanized iron wire on the roller of ratchet.

Application No. is CN201520593282.0 utility model patents to disclose a kind of electric power first-aid cord holder, the patent institute The technical solution of record does not have self-locking function, and manual operation rotating handle realizes the function of stringing, low efficiency, labor intensity Greatly, especially in high altitude operation.

Utility model content

The utility model is achieved through the following technical solutions:

I.e. a kind of power line construction cord holder, including shell, housing forward end are fixed with fixed plate, enclosure interior peace Equipped with rotating roller, rope is wound in rotating roller, one end of rope is fixed in rotating roller, and the other end of rope is hingedly mounted on In fixed plate, rope is around pulley setting, and before pulley is mounted in U-shaped folder plate, the front end of preceding U-shaped folder plate is hingedly equipped with front hanging Hook, housing rear end are fixedly installed with swingle, and the end of swingle is hinged with rear U-shaped folder plate, and it is hingedly hinged to pass through rear U-shaped folder plate Extension bar is equipped with aft hook on hinge bar, passes through shell and is equipped with shaft, rotating roller is fixedly mounted in shaft, also solid in shaft Dingan County is equipped with a worm gear, is fixed with L-type mounting plate on shell, and servo motor, servo electricity are fixedly installed on L-type mounting plate Machine has worm screw by shaft coupling connection, and worm and wheel is meshed, and the angle of spiral of worm screw is rubbed less than the equivalent of the field of conjugate action Angle is wiped, one end of worm screw supports by L-type mounting plate, and the other end of worm screw is by the bearing mounting base branch that is fixed on L-type mounting plate Support.

Servo motor controls the steering of the revolving speed of rotating roller by worm and gear rotating mechanism, provides not only work effect Rate, greatly reduces the labor intensity of operator, and has reliable self-locking function, improves safety coefficient.

Further preferably, the rope is wirerope.

Further preferably, handle is fixed on the upper surface of the shell.

Compared with prior art, beneficial effect possessed by the utility model is:

Specific embodiment

Below against attached drawing, specific embodiment of the present utility model is described in further detail.

A kind of power line construction cord holder as shown in Figure 1 and Figure 2, including shell 1, it is fixed on the upper surface of shell 1 Equipped with handle 19,1 front end of shell is fixed with fixed plate 5, and rotating roller 2 is equipped with inside shell 1, rope is wound in rotating roller 2 Rope 4, one end of rope 4 are fixed in rotating roller 2, and the other end of rope 4 is hingedly mounted in fixed plate 5, and rope 4 is around cunning 7 setting of wheel, before pulley 7 is mounted in U-shaped folder plate 6, the front end of preceding U-shaped folder plate 6 is hingedly equipped with front hook 8, and 1 rear end of shell is fixed Swingle 9 is installed, the end of swingle 9 is hinged with rear U-shaped folder plate 10, it is hinged with hinge bar 11 across rear U-shaped folder plate 10, Aft hook 12 is installed on hinge bar 11, shell 1 is passed through and is equipped with shaft 18, rotating roller 2 is fixedly mounted in shaft 18, shaft 18 On be also fixedly installed with a worm gear 3, L-type mounting plate 13 is fixed on shell 1, is fixedly installed with and watches on L type mounting plate 13 Motor 17 is taken, servo motor 17 has worm screw 14 by the connection of shaft coupling 16, and worm screw 14 is meshed with worm gear 3, and the spiral shell of worm screw 14 Spin line lift angle is less than the equivalent friction angle of the field of conjugate action, and one end of worm screw 14 supports by L-type mounting plate 13, the other end of worm screw 14 by The bearing mounting base 15 being fixed on L-type mounting plate 13 supports.
