Description

Adjustable cable hoop

technical field

The utility model relates to an adjustable optical cable hoop, which belongs to the field of electric power engineering.

Background technique

When erecting the optical cable, the optical cable hoop and the sling are usually used to pull the optical cable to support the optical cable. During the erection process, the end of the sling is usually hooked on the hoop, and the hooked sling cannot be Adjust the tightness of the fiber optic cable, which cannot adapt to different working conditions, environments and cable properties. It is easy to cause the fiber optic cable to be too loose or too tight, which affects the safety of use and the service life of the fiber optic cable. Moreover, the ends of adjacent fiber optic cables are usually closed It is hung on the respective hoops, and the fastening installation direction of the hoops is parallel to the direction of the optical cable. There are many hoops to install, and the operation is cumbersome.

Utility model content

The technical problem to be solved by the utility model is to provide an adjustable optical cable hoop which has a reasonable structure, can adjust the tightness of the optical cable, and improves the erection efficiency and quality.

The adjustable optical cable hoop described in the utility model includes two oppositely installed hoop plates, one end of the hoop plate is symmetrically provided with a mounting plate, the mounting plate is located outside the joint of the two hoop plates, and brackets are respectively arranged on the mounting plate, The rotating shaft is installed horizontally on the bracket, and the ratchet is installed on the rotating shaft. The ratchet, the active swing lever and the non-return pawl are respectively installed on the corresponding ratchet. One end of the active swing lever is connected to the rotating shaft, and the other end is installed on the connecting frame through the rotating shaft. Installed on the bracket, the ratchet is hinged with the active swing rod through the rotating shaft, the non-return ratchet is hinged with the mounting plate, a coil spring is arranged between the non-return ratchet and the mounting plate, and a handle is installed at one end of the rotating shaft.

A symmetrical mounting plate is arranged at one end of the hoop plate, and the mounting plate is located outside the joint of the two hoop plates. This structure can fasten the ends of the two optical cables to the same hoop at the same time. The direction of the buckle of the hoop The direction perpendicular to the optical cable can reduce the number of hoops installed and save space; the mounting plate is connected to the ratchet mechanism through a bracket. When in use, wrap the sling around the rotating shaft and turn the handle so that the rotating shaft can only rotate in one direction , for tensioning or loosening, when the operation in the opposite direction is required, move the non-return pawl to make the non-return pawl leave the non-return position to realize the reverse rotation of the rotating shaft, so as to facilitate the operation of tensioning or loosening the sling Loose, improve erection quality and use safety.

The wear-resistant layer is fastened inside the hoop plate, and the wear-resistant layer is set as a rubber layer distributed with hemispherical protrusions. Strengthen the fastening strength of the hoop to avoid the rotation of the hoop caused by uneven force applied to the optical cables on both sides.

The beneficial effects of the utility model are:

The structure is compact and reasonable, which is convenient for adjusting the tightness of the optical cable, improving the quality and efficiency of erection, and the setting of the ratchet mechanism is convenient for adjusting and positioning the optical cable at the fixed position, with low cost and convenient operation.

In the figure: 1, bolt 2, hoop plate 3, sling 4, ratchet 5, connecting frame 6, rotating shaft 7, handle 8, bracket 9, non-return pawl 10, wear-resistant layer 11, pawl 12, active Fork 13, mounting plate.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1 and Figure 2, the adjustable optical cable hoop described in the utility model includes two hoop plates 2 installed by bolts 1, and one end of the hoop plate 2 is symmetrically provided with a mounting plate 13, and the mounting plate 13 is located on the two sides. On the outside of the joint of the hoop plate 2, a bracket 8 is respectively arranged on the mounting plate 13, a rotating shaft 6 is installed horizontally on the bracket 8, a ratchet 4 is installed on the rotating shaft 6, and a ratchet 11, an active swing bar 12 and a stopper are respectively installed on the corresponding ratchet 4. Back ratchet 9, one end of active pendulum 12 is connected with rotating shaft 6, and the other end is installed on connecting frame 5 through rotating shaft, and connecting frame 5 is installed on bracket 8, and ratchet 4 is hinged with active pendulum 12 through rotating shaft, and non-return ratchet The pawl 9 is hinged with the mounting plate 2, a coil spring is arranged between the non-return ratchet 9 and the mounting plate 13, and a handle 7 is installed at one end of the rotating shaft 6. A wear-resistant layer 10 is fastened inside the hoop plate 2, and the wear-resistant layer 10 is set as a rubber layer distributed with hemispherical protrusions.

During use, the sling 3 is wound on the rotating shaft 6, and the handle 7 is turned, so that the rotating shaft 6 can only rotate in one direction, as shown in Fig. When operating in the opposite direction, toggle the non-return pawl 9 so that the non-return pawl 9 leaves the non-return position to realize the reverse rotation of the rotating shaft. After the adjustment is completed, the non-return pawl 9 returns to the The initial non-return state is positioned so as to facilitate the operation of tensioning or loosening the suspension rope 3 .
