DD156859A1 - HAKENOESE, PREFERABLY FOR REMOVING HEADER PARTS - Google Patents

Abstract

The invention relates to a Hakenoese, which is preferably used for pulling out of conductors as a safe, fast closing or looseable and less susceptible connection member between the traction cable and the conductor cable. The Hakenoese consists of two identical, mutually mirror-inverted arranged and interlocking in the closed position hooks, which are provided for receiving a hinge axis in the hook shank with a bearing eye. According to the invention, the inner edges of the hook shank and the hook breast of both hooks run parallel to one another, wherein the distance of the parallel inner edges corresponds to the diameter of the rope to be hammered.

Hook eye, preferably for pulling out of conductors

Field of application of the invention

The invention relates to a hook eye, which is preferably used for pulling out of conductors as a safe, fast schiießbsw, detachable and less susceptible to interference connecting element between a pull rope and the conductor.

Characteristic of the known technical solutions

In the construction of power transmission lines, it is known to connect the pull cable to the conductor by means of a vortex connector. Rope loops, pull stockings or the like are attached directly to the vertebral connector with a grub screw.

Due to the effects of weather and pollution, the connection of the pull cable to the conductor cable is often associated with considerable difficulties; '

As a link in the horizontal pulling loads already provided with a safety device tow hook (DD-WP 29 331) has been proposed. The securing device is intended to prevent the automatic unhooking of tensioned tension members from the load hook by a locking member locking under load locking the hook opening

 JCJachteil this solution is that in case of contamination

continuous proper functioning of the safety device is not guaranteed. The proposed tow hook can not be used as a link between a pull rope and the conductor in the Hoehspannungsfreileitungsbau because of the occurring high rope-breaking speed.

Sin further known load hooks (DB-AS 2 336 970) consists of two identical and mutually mirror-inverted hooks * Me hooks are each provided with a bearing eye in the hook shank _$ is guided by a hinge axis. The hook tips overlap in the closed position * The load hook has a pawl hinged to the hook on _f so that it can be locked in the closed position «

Kachteil this load hook is the need for the pawl, which is due to the crane hook-like design of the tow hook and the associated movable position of the embarked rope. The towing hook is unsuitable as a connecting link between the traction cable and the ladder cable when pulling out ropes in the Hoehspannungsfreileitungsbau ₉ because when passing the rope guide rollers unintentional opening of the pawl can not be excluded _e

Another pull hook (US-PS 3,638,283) consists of two S-shaped and mirror-image. Hook arranged to each other. These hooks are hinged together in their middle area. The tow hook can be locked by means of a force acting on the connecting shaft spring assembly _e

Disadvantage of this arrangement is the complicated structure of the lock «their safe function is not secured at high swirl velocities of the rope and dirt *

Object of the invention

-3- 228236 %

The aim of the invention is to reduce the time required for the installation of a detachable cable connection, especially when removing conductors in power transmission line construction «

Explanation of the essence of the invention

The invention has for its object to provide a connecting link for the detachable connection of cables in the overhead cable of power transmission lines. The connecting link should withstand the effects of the weather, the risk of contamination as well as the loads arising when passing pulleys u & d do not require any special safety arrangements such as pawls, circlips or the like for safe operation. The object is achieved by two identical hooks are arranged mirror images of each other. The overlapping in the closed position hooks are provided for receiving a hinge axis in the hook shaft with a bearing eye. According to the invention, the inner edges of the hook shaft and the hook breast parallel to each other »The distance between the parallel inner edges corresponds to the diameter of a rope to be driven«

embodiment

The invention will be explained in more detail below using an exemplary embodiment.

In the accompanying drawing shows

Fig. 1i is the front view of the hook eye according to the invention Fig. 2ι the front view of a hook

As can be seen from FIG. 1, the drawbar eye, which can be set as a fast closing or releasable connecting member between a pull rope and a conductor cable 4, consists of two identical hooks. These hooks are in a known manner

arranged mirror-inverted to one another, wherein in the closed position, the hook tips'.über overlap with the Hakenschäften -1. The hook shafts 1 are provided with a bearing eye through which a hinge axis 3 is guided. The inner edges of the hook shank 1 and the hooked breast 2 of both hooks (Fig. 2) are guided parallel to each other "Dei ¹ distance of the parallel inner edges _s d _e h" the inner width of the hook eye corresponds to the diameter of the rope to be taken 4 _e

After spreading the two hook parts, the cable loop 4 is inserted. "The hooks are compressed * At the following tensile stress, the cable 4 slides to the front part dex ⁴ hook loop so that an unintentional opening is excluded«. <
