Abstract

The utility model discloses a hook supplement-device for optical cables, mainly composed of a U-shaped frame and an extension rod. The utility model is characterized in that a pair of torsion springs, a pair of tension springs and a pair of retractors are arranged on the U-shaped frame; when the optical cable needs to be supplemented with the optical hook, the optical hook can be put in the U-shaped frame, and the torsion springs at the bottom of the U-shaped frame are used for blocking the optical hook and the retractors on both ends of the U-shaped frame are used for pulling the optical hook, and then the extension rod can be hung on an overhead steel stranded wire and the optical cable. The supplement-device has the advantages that the design is reasonable, the operation is convenient and the use method is easy to master. The supplement-device is a kind of new skill worthy to be popularized.

Description

A kind of Optical hanger is augmented device

A kind of Optical hanger is augmented device, belongs to the device of telecommunications aerial fiber cable hook.

The telecommunications aerial fiber cable is optical cable fixedly to be suspended on the overhead steel strand by orderly arrangement with numerous Optical hanger, because behind the fiber cable laying be permanent use.By the influence of long-time wearing and tearing and external force, the intensity of hook can go down to some extent, and has the part hook to come off, and causes the direct intensity that influences optical cable itself, safeguards the hook of augmenting that the staff of optical cable will be regular for this reason, and is unblocked with the assurance telecommunications.Up to the present, this work all adopts " optical cable coaster " or " flexible pole-climbing " to finish.But state in the use two kinds the device work process in have many drawbacks, at first be to use the optical cable coaster, when laying optical cable, because on the steel strand wire without any annex, coaster can pass through smoothly, but situation is just different in maintenance work, the one, because overworked the fixedly hook of optical cable on the steel strand wire, coaster can not slide smoothly; The 2nd, both made and exempted to slide by force also and must unavoidably other hook be bumped or be shifted: three are to use the optical cable coaster to increase the operation of work, lose time and the labour.Next uses scalable cat ladder; The one, cat ladder also has 3 meters long after shortening, must have lorry to transport to the working site during use; The 2nd, it is long that the cat ladder elongation can reach 4-5 rice, wants 3 people it could be erected during work at least.

The purpose of this utility model is that a kind of Optical hanger of design is augmented device, to solve problems of the prior art.

The utility model is achieved like this, a kind of Optical hanger is augmented device, mainly is made up of U type frame and extension bar, it is characterized in that: U type frame is provided with a pair of torsion spring and a pair of extension spring and a pair of drag hook.

Torsion spring described in the utility model is arranged on the bottom of U type frame, and a pair of extension spring is arranged on the two ends crect ear of U type frame.

A pair of drag hook described in the utility model is fixed on the top of U type frame crect ear, and an end of extension spring is attached thereto, and the other end is connected with crect ear.

It is reasonable in design that a kind of Optical hanger is augmented device, simple in structure, makes easily, and execute-in-place is convenient, economizes on the use of funds, equipment, is a kind of equipment of augmenting of desirable communications optical cable.

Accompanying drawing has provided a kind of Optical hanger and has augmented device.

Fig. 1 augments the front view of device for a kind of Optical hanger.

Fig. 2 augments the vertical view of device for a kind of Optical hanger.

Part detail: 1-U type frame 2-extension bar 3-torsion spring 4-extension spring

5-crect ear 6-drag hook

Below in conjunction with accompanying drawing a kind of Optical hanger being augmented device is further described.

In view of easy to process, U type frame and the extension bar of augmenting device are designed to two bodies, U type frame and the connected mode of extension bar can adopt welding or be threaded all can, U type frame and extension bar all adopt the round steel of Φ 10 to process.A pair of crect ear on the U type frame processes and is welded on the middle part in U type frame two outsides with the round steel of Φ 3.Drag hook one end opening is installed in the top of crect ear, an end of extension spring is connected the middle part of hook, be welded with on the bottom extension bar that the other end is connected on the crect ear, a pair of torsion spring is fixed on U type frame two links in order to the lengthening extension bar, can during execute-in-place Optical hanger be placed in the U type frame according to existing operational circumstances lengthening extension bar.And two long handles of Optical hanger, two torsion springs with U type frame bottom are blocked, again drag hook is held, connect extension bar, hang on overhead steel strand and the optical cable and get final product, it is easy to use that this augments device, using method and should grasping, and cost very low be a kind of new technology that is worthy to be popularized.Very high using value is arranged.
