Description

Cable joint tensioning and reinforcing device

Technical Field

The utility model belongs to the technical field of cable joint reinforcement, and particularly relates to a cable joint tensioning and reinforcing device.

Background

The cable is electric energy or signal transmission equipment composed of several or several groups of wires, and because the length of a single cable is limited, in the actual use process, all the sections of cables are often required to be connected into a whole to form a continuous line, all the sections of cables are directly connected by using cable joints, the cable joints are used for locking and fixing incoming and outgoing wires, the waterproof, dustproof and vibration-proof functions are achieved, and the cable joints are also positions where the cables are easy to break and loose cores occur, so that the cable joints are required to be reinforced to improve the connection stability of all the sections of cables in order to ensure the normal work of the whole cable.

In the existing cable connection process of each section, one mode is to strengthen the connection stability of the cable connector, so that the connection stability of each section of cable connector is higher, and the other mode is to use the existing universal connector for cable connection and strengthen the cable connector through an independent strengthening device. The patent of application number 201821313498.7 discloses a screw reinforced middle joint protection shell of a high-voltage cable, as shown in fig. 5, two reinforcing sleeves at two ends of the middle joint protection shell of the high-voltage cable are connected and fixed through screws and bolts, in the aforesaid patent, the reinforcing sleeves need to be sleeved on a cable body to slide so as to conveniently adjust the positions of the reinforcing sleeves and enable the screws to penetrate through the reinforcing sleeves to connect, on the other hand, the reinforcing sleeves need to play a role in reinforcing the cable joint, and a large friction force must be provided between the reinforcing sleeves and the cable body so that the reinforcing sleeves can be tightly sleeved with the cable body, but the difficulty of sliding the reinforcing sleeves on the cable body has a contradictory relation with the magnitude of the friction force between the reinforcing sleeves and the cable body, so that the reinforcing sleeves are difficult in practical operation

Therefore, it is necessary to provide a cable joint tightening and reinforcing device, so that the connection between the reinforcing device and the cable body is tighter, the reinforcing effect is improved, the disassembly is convenient, and the repeated use or replacement is convenient.

Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in fig. 1-3, the cable joint tensioning and reinforcing device comprises a hoop 1, a first connecting surface 2, a second connecting surface 3 and a connecting chain 4, wherein the hoop 1 is positioned at two ends of a cable joint 6 and is tightly held by a cable body 7, one end of one valve of the hoop 1 is fixedly provided with the first connecting surface 2, one end of the other valve of the hoop 1 is fixedly provided with the second connecting surface 3, the first connecting surface 2 and the second connecting surface 3 are positioned at one end, close to the cable joint 6, of the hoop 1 and are perpendicular to the axis of the hoop 1, a through hole 5 is formed in the first connecting surface 2, and two ends of the connecting chain 4 respectively penetrate through the through hole 5 in the first connecting surface 2 of the through hole 5 at two ends of the cable joint 6 and are connected with the first connecting surface 2; the number of the through holes 5 is 2; the two halves of the anchor ear 1 are locked by 4 bolts, and the 4 bolts are distributed on two sides of the anchor ear 1, and each side is provided with 2 bolts. After two sections of cables are connected through the cable connector 6, the anchor ear 1 is used for holding the cable bodies 7 at two ends of the cable connector 6, then the anchor ear 1 is moved, as one end of one anchor ear 1 is fixedly provided with the first connecting surface 2, two ends of the connecting chain 4 respectively penetrate through the through holes 5 on the first connecting surface 2 of the through holes 5 at two ends of the cable connector 6 and are connected with the first connecting surface 2, the anchor ear 1 is moved to enlarge the distance between the anchor ears 1 at two ends of the cable connector 6, so that the connecting chain 4 is in a tensioning state, when the connecting chain 4 is in a tensioning state, the anchor ear 1 is not moved, the anchor ear 1 is used for locking and fastening the two anchor ears of the anchor ear 1 by bolts, so that the anchor ear 1 holds the cable bodies 7, at the moment, the anchor ear 1 and the cable bodies 7 have larger friction force, meanwhile, the anchor ear 1 is tensioned by the connecting chain, the first connecting surface 2 is relatively close to the distance from the cable connector 6, the tensioning effect of the connecting chain 4 is not easy to deform the cable bodies 7, and the anchor ear 1 is not easy to deform the two sections of the cable connector 6 to receive the tensioning force of the connecting chain 4, so that the anchor ear 1 is strengthened by the anchor ear 4, and the reinforcing effect on the cable connector is improved. In the pulling process of the cable, the connection part of the cable connector 6 and the cable body 7 may have a bending state, when the bending direction of the connection part of the cable connector 6 and the cable body 7 faces the direction of the connecting chain 4 (as shown in fig. 4), the first connecting surface 2 slides along the connecting chain 4 according to the actual bending state of the cable so as to adapt to the bending state of the cable, and meanwhile, the connecting chain 4 can also bend so as to adapt to the bending state of the connection part of the cable connector 6 and the cable body 7, so that the probability that the connecting chain 4 is deformed and damaged due to radial force when the bending state of the connection part of the cable connector 6 and the cable body 7 occurs is reduced. After the cable pulling work is completed, the joint of the cable connector 6 and the cable body 7 is straightened, the connecting chain 4 returns to a tensioning state again, the cable connector 6 is tensioned, and the breaking probability of the cable connector is reduced.

The working process of the utility model comprises the following steps: after two sections cable junction department are connected, use the staple bolt to hold the cable body at cable junction both ends respectively, the staple bolt has not held tightly the cable body this moment, can hold the staple bolt of cable body through sliding, change the distance between the staple bolt at cable junction both ends, when the distance between the staple bolt makes the link be strained, stop sliding the staple bolt, and use the bolt to lock the two petals of staple bolt, the rethread fastening bolt makes the staple bolt hold tightly the cable body, through the tensioning effect of link at this moment, can take up the cable junction, play the reinforcement effect.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the utility model as defined by the appended claims.
