RU234707U1 - Combined connecting element for cable structures - Google Patents

Abstract

The utility model relates to equipment that includes cable elements that are pivotally connected to other equipment units that perform the function of protecting the cable from mechanical damage at the bending point and eliminating dangerous gaps in the hinge pair. The combined connecting element for cable structures includes a thimble 1, branches with a threaded hole 3 and with a smooth hole 6, with a protective partition 4 and a threaded pin 2. The device operates as follows. The cable is threaded into a channel, placed in the groove of the thimble and secured in the form of a loop. The branches are mated in a hinged connection with the mating element, which is closed by means of a threaded pin, thereby ensuring the fixation of the cable in a position that does not allow the formation of gaps that are dangerous for users.

Description

The utility model relates to equipment that includes cable elements that are pivotally connected to other equipment units, performing the function of protecting the cable from mechanical damage at the bending point and eliminating dangerous gaps in the hinge pair.

The problem solved by the utility model is as follows.

Often the cause of destruction of cable elements are sharp-edged parts located at the bending point, when using a thimble as a structural element of a cable loop. An example of such a configuration is the use of cables with rigging brackets.

A rigging clamp (https://zaglushka.ru/takelazhnaya-skoba-s-plastinoi-bezopasnosti-vypolnena-iz-nerzhaveyushchei-stali-m04-3110) is known, used in cable devices for connecting a cable with a structural element. The clamp is equipped with a protective partition that eliminates the gap in the hinged connection. The second known device is a thimble (https://zaglushka.ru/metallicheskii-koush-iz-ocinkovannoi-stali-dlya-kanata-diametrom-22-mm-s04-1022), which forms a cable loop that protects cable elements from fractures.

The combination of these technical solutions, as the closest to the declared technical essence and the achieved result, are accepted as its prototypes.

The disadvantages of these technical solutions include the fact that, due to the sharp edges of the bracket, the rope is destroyed during operation, and the thimble has an opening that is dangerous for users.

According to the utility model, a thimble with a closed aperture, branches of a rigging loop with smooth and threaded holes for installing a pin that closes the hinge joint are formed in a single metal casting. The thimble groove at the bottom of the loop is closed by a protective partition that forms a channel through which the cable passes. The size of the partition is significantly increased compared to the prototype, it does not have sharp edges that can damage the cable. In the part facing the hinge, the partition is limited by a curvilinear surface that repeats the surface of the mating element of the hinge pair to achieve a minimum gap at the mating point.

The declared set of essential features ensures the achievement of a technical result, which consists in the fact that simple design means ensure the possibility of safe operation of structures with articulated cable connections and protection of cables from mechanical damage.

The essence of the utility model is explained by drawings.

where 1 is a thimble, 2 is a threaded pin, 3 is a branch with a threaded hole, 4 is a protective partition, 5 is a channel for a cable, 6 is a branch with a smooth hole.

The combined connecting element for cable structures includes a thimble 1, branches with a smooth hole 6 and with a threaded hole 3, with a protective partition 4, a threaded pin 2 and a channel for the cable 5.

The device works as follows.

The cable is threaded through the channel and placed in the groove of the thimble and secured in the form of a loop. The branches are connected in a hinged joint with the counterpart, which is closed by means of a threaded pin, thereby ensuring that the cable is fixed in a position that does not allow the formation of gaps that are dangerous for users.

Claims (1)

A connecting element, which is a combination of a thimble with a closed opening and a rigging bracket with a protective partition repeating the curvature of the mating element of the hinge joint, made as a single unit in the form of a metal casting, providing protection for the suspension cable element at the bending point and eliminating a dangerous gap at the joint of the hinge pair.
