Problems solved by technology

[0002] The traditional optical cable erection is to use a set of fixed pulleys to adjust the sag of the optical cable. During the operation, multiple people are required to cooperate and pull the rope hard. After repeated adjustments, the required sag can be achieved. The operation is complicated, time-consuming and laborious. The work efficiency is low, the labor intensity of the operators is high, and it is limited by the working environment of the construction site; although the lever hoist is used to adjust the sag of the optical cable, although it saves labor, because the lever hoist is relatively heavy and the volume is large, it is difficult for transportation and construction. cause great inconvenience
[0003] At present, the wire tensioner commonly used in overhead line tightening tools is easy to operate, but this type of wire tensioner is equipped with a wire gripper, and the wire gripper is used to clamp the wire and adjust the wire tension, which is easy to cause damage to the optical cable and is not suitable for Optical cable erection tight line

Embodiment 1

[0017] Depend on Figure 1 to Figure 2 It can be seen that the present invention includes a connecting frame 2 and a sheave 4 arranged thereon, the left end of the connecting frame 2 is provided with a fixed hook 1, the side of the connecting frame 2 is provided with a wrench 5, and the wrench 5 adopts a ratchet type wrench. A wire rope 3 is wound on the sheave 4, and the free end of the wire rope 3 is fixed with a traction hook 7, which is hooked with the pre-twisted wire tension clamp 6, and the right end of the connecting frame 2 is provided with a fixed hanging ring 9, The steel wire rope 3 is provided with a movable pulley 8, and the movable pulley 8 is located between the traction hook 7 and the fixed link 9; a rope cover 10 connected with the fixed hook 1 is also provided, and the rope cover 10 is a piece with two free ends. Ring of wire rope.

[0018] The movable pulley 8 is provided with an anti-off safety hook, and the traction hook 7 is an anti-off safety hook. Usi...

Embodiment 2

[0023] The difference between embodiment 2 and embodiment 1 is: when in use, hang the traction hook 6 on the fixed hanging ring 9, hang the pre-twisted wire tension clamp 6 on the hook of the movable pulley, and utilize the principle of labor-saving of the movable pulley, Reduce labor intensity and improve work efficiency.

[0024] For general optical cable line adjustment operations, Embodiment 1 can meet the requirements of use. When the optical cable to be adjusted is long and has a large traction force, Embodiment 2 is more suitable.

[0025] The invention is light in weight, small in size, easy to carry, has no damage to the optical cable, and is especially suitable for the fluidity of the optical cable erection and the diversity of the working environment.

Abstract

The invention discloses an optical cable tightener, and relates to the technical field of overhead line regulation devices. The optical cable tightener comprises a connecting frame and a rope sheave arranged on the connecting frame, a fixation hook is arranged at the left end of the connecting frame, a wrench is arranged on the side portion of the connecting portion, a steel rope winds the rope sheave, and a traction hook is fixed to the free end of the steel rope to be connected with a preformed armor rod strain clamp in a clamped mode. The optical cable tightener has the advantages of being simple in structure, light in weight, small in size, convenient to carry and use, free of damage to an optical cable, capable of regulating the sag degree of the optical cable to meet a required standard with time and labor saved, reducing labor intensity, improving working efficiency, and being suitable for mobility of optical cable erection and the diversity of operation environments.
