Abstract

The utility model provides a stress cone push-and-pull frock, including C shape cassette, the joint has two semi-circular fixtures in the cassette, fixtures constitute circularly. Before the cable conductor wire core is connected, the stress cone is sleeved on the cable long-end insulating wire core to be connected with the cable conductor; then the clamping seat and the clamping apparatus are assembled and clamped on the oblique shoulder at one side of the stress cone, and finally a force application tool such as a lever block or an electric block is used for applying force to the clamping seat, so that the stress cone is uniformly pulled, the stress cone moves to a process position to one side at a constant speed, manpower is saved, and installation time is saved.

Description

Stress cone push-and-pull tool

Technical Field

The utility model relates to a power cable technical field specifically is a stress cone push-and-pull frock.

Background

In recent years, the cable manufacturing technology in China has been developed greatly, but the development of high-voltage cable accessories is relatively delayed, and researches show that the problem of cable accessory faults is that the probability of occurrence of power system faults accounts for more than half of the probability of occurrence of power system faults. The cable accessory comprises a cable terminal and a connector, wherein in order to connect the conductor with other conductors or electrical equipment, the metal shielding sheath and the insulation are required to be cut off and stripped in the manufacturing process of the related cable terminal, and a bare cable line needs to be provided with a fine stress cone so as to solve the problem of axial stress concentration at the cable connector when the cable is electrified.

The prefabricated cable intermediate joint meets the requirement of the stress cone on the insulating holding force (interface pressure) of the cable through the elastic recovery of the silicon rubber body. Because the holding force is very big, the stress cone moves the degree of difficulty on cable insulation core big, is difficult to remove the stress cone to the position of technological requirement.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problem that a stress cone on a traditional cable is difficult to move is solved.

The utility model provides a stress cone push-and-pull frock, including C shape cassette, the joint has two semi-circular fixtures in the cassette, fixtures constitute circularly.

Before the cable conductor wire core is connected, the stress cone is sleeved on the cable long-end insulating wire core to be connected with the cable conductor; then the clamping seat and the clamping apparatus are assembled and clamped on the oblique shoulder at one side of the stress cone, and finally a force application tool such as a lever block or an electric block is used for applying force to the clamping seat, so that the stress cone is uniformly pulled, the stress cone moves to a process position to one side at a constant speed, manpower is saved, and installation time is saved.

Furthermore, the clamping seat is provided with a concave table, the excircle of the clamping apparatus is provided with a convex ring, the clamping apparatus is clamped with the concave table, and the convex ring is clamped with the end part of the clamping seat. So set up, the cassette is more firm with the fixture joint, and during the cassette atress, be difficult for droing.

Furthermore, two lifting lugs are arranged on the clamping seat. The lifting lug is used for fixing the soft rope or the chain, so that the clamping seat is stressed conveniently.

Further, the lifting lugs are symmetrically arranged relative to the clamping seat opening. So set up, cassette atress is even.

Furthermore, an annular clamping groove is formed in the middle of the lifting lug. So set up, the flexible rope or the chain on the lug are difficult for droing.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a front view of the present invention;

FIG. 3 is a schematic view of the structure of the present invention mounted on a stress cone;

in the figure: 1. a card holder; 2, clamping a tool; 3. lifting lugs; 11. a concave platform; 21. a convex ring; 31. a clamping groove.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the utility model relates to a stress cone push-and-pull frock, including C shape cassette 1, the joint has two semi-circular fixture 2 in the cassette 1, fixture 2 constitutes circularly. The clamping seat 1 is provided with a concave platform 11, the excircle of the clamping device 2 is provided with a convex ring 21, the clamping device 2 is clamped with the concave platform 11, and the convex ring 21 is clamped with the end part of the clamping seat 1. So set up,

cassette

1 and 2 joints of fixture are more firm, and during the cassette 1 atress, be difficult for droing.

As shown in fig. 2, two lifting lugs 3 are arranged on the clamping seat 1, and the lifting lugs 3 are used for fixing a chain (a soft rope can also be used), so that the clamping seat 1 is convenient to bear force; the middle position of the lifting lug 3 is provided with an annular clamping groove 31, so that the chain on the lifting lug 3 is not easy to fall off; the lifting lugs 3 are symmetrically arranged relative to the opening of the clamping seat 1, so that the clamping seat 1 is stressed uniformly.

As shown in fig. 3, before the cable conductor core is connected, a stress cone is sleeved on the cable long-end insulated core to connect the cable conductor; then the clamping seat 1 and the clamping device 2 are assembled and clamped on an inclined shoulder at one side of the stress cone, one end of the chain is fixed on the lifting lug 3, the other end of the chain is connected to a lifting hook of the lever block or the electric block, finally the lever block or the electric block is started, the chain is tightened, force is applied to the clamping seat 1, and therefore the stress cone is uniformly pulled, the stress cone moves to a technological position to one side at a constant speed, manpower is saved, and installation time is saved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
