Abstract

The utility model relates to a power conducting wire hydraulic connection device. The usual hydraulic connection is that the outer part of a metal connecting tube is extruded a plurality of times to be deformed to impact a conducting wire, so the power needed by compression joint is large, the time is long, and the equipment is bulky. The hydraulic joint of the utility model is provided with a hydraulic push disk in a tube body, and a push arm notch is arranged on a shell body. A push arm is extended in the push arm notch to carry out interpolation and extrusion, and the component in a joint tube is connected with the conducting wire in an impaction mode. Because the joint tube is not deformed, the needed power is small, the time is short, and the equipment is correspondingly light. The utility model can be widely used on the connecting tube and the anti-tension tube.

Description

A kind of electrical lead hydraulic joint

The utility model relates to a kind of jockey of electrical lead, specifically refers to a kind of electrical lead hydraulic joint.

Usually the connection of the hydraulic pressure of electric power overhead lead is that the joint of two leads is put into metal joint pipe two-port, uses hydraulic test repeatedly to push in metal joint pipe outside then, makes it distortion, compresses lead, reaches the connection purpose.But the mode of this external hydraulic has following shortcoming: 1. will be with the crimp of metal joint pipe, and required strength is big and will push repeatedly, and the crimping time is long, inefficiency.2. the hydraulic test heaviness can reach several tons of weights, and is not portable, cost height, inconvenience when going out operation.

The purpose of this utility model be to provide a kind of hydraulic pressure laborsaving, save time, hydraulic test is light and handy, the electrical lead hydraulic joint that cost is low.

The utility model adopts following technical scheme, and the hydraulic pressure push-plate is set in the electrical lead hydraulic joint, and offers a push arm notch on the joint body.

Design a kind of hydraulic means that is used for above-mentioned hydraulic joint again, this hydraulic means comprises oil pump, petroleum pipeline, the push arm device, its push arm device is by left and right push arm, left and right push rod, and housing is formed, left and right push arm, push rod device is in housing, and an end of push arm stretches out outside the housing, during use push arm is put in the push arm notch of above-mentioned hydraulic joint, promote the hydraulic pressure push-plate and push, make hydraulic joint pipe inner part compress lead and reach the connection purpose to both sides.

Because the utility model uses in the hydraulic pressure and pushes away device, when making hydraulic pressure, will the crimp of metal joint pipe, required hydraulic pressure strength greatly reduces, and the hydraulic pressure time is short, and corresponding hydraulic test is also very light and handy, and about about 20 kilograms, cost reduces.

Below in conjunction with accompanying drawing utility model is elaborated.

Fig. 1 is an electrical lead hydraulic joint hydraulic pressure pre-structure schematic diagram.

Fig. 2 is a structural representation behind the electrical lead hydraulic joint hydraulic pressure.

Fig. 3 is the utility model hydraulic means stereogram.

Fig. 4 is the utility model device push arm device cutaway view.

With reference to Fig. 1, Fig. 2, device aluminium pawl 9 in the body 10 of electrical lead hydraulic joint, steel folder 8, push-plate 7 parts such as grade, again body 10 two ends are pressed and be cone, middle one section level, be convenient to hydraulic pressure push-plate 7 and move, in the inner chamber 6 of body 10, hydraulic pressure push-plate 7 is set, on the housing of body 10, offer push arm notch 11, sheath 1 is housed in the body 10, aluminium pawl 9, steel folder 8, lead 2 is inserted by the two-port of body 10, steel core 3 is exposed in the front end aluminium lamination strip off of lead 2, steel folder 8 is clamped steel core 3, and the aluminium pawl is caught lead 2 and steel folder B, when left push arm 4, right push arm 5 is subjected to hydraulic drive when both sides are pushed, hydraulic pressure push-plate 7 extruding steel folders 8, aluminium pawl 9 because the two ends of body 10 are cone, forces the inner conical surface of aluminium pawl 9 lead pipe bodies 10 to advance, lead 2 parts are released to port, sheath 1 part is released port, and lead aluminium thigh and steel folder 8 are tightly bitten by the aluminium tooth on the aluminium pawl 9, and steel core 3 is tightly bitten by the steel tooth on the steel folder 8, make lead 2, aluminium pawl 9, steel presss from both sides 8 crimping becomes an integral body, reaches the connection purpose.

With reference to Fig. 3, Fig. 4, the hydraulic means that is used for above-mentioned hydraulic joint comprises oil pump 20, petroleum pipeline 17, push arm device 13, petroleum pipeline 17 connects oil pump 20 and push arm device 13, and its push arm device 13 is by a left side,

right push arm

4,5, a left side,

right push rod

15,16, housing 21 is formed, a left side,

right push arm

4,5,

push rod

15,16 all are contained in outside the housing 21 left side, right push arm 4, an end of 5 is outside shell nozzle 22 stretches out housing 21, on housing 21, open an oil-in 14, when carrying out hydraulic pressure, with

push arm

4,5 put in the hydraulic pressure notch 11, shake handle 18, oil is compressed into the push arm device from oil-in 14, promote a left side, right push rod promotes Left-wing Federation's plate 12, right yoke plate 23 then to two side shiftings, thereby make

push arm

4,5 to both sides extruding hydraulic pressure push-plate 7, make hydraulic joint pipe inner part compress lead 2, reach the connection purpose, at this moment, tighten by-pass valve control 19, can keep hydraulic pressure, after the successful connection, unclamp control valve 19, oil returns oil pump 20 from push arm device 13, push arm 4, but 5 hand-resets.

Left side push arm 4, push rod 15, Left-wing Federation's plate 12 can be welded into integral body, right push arm 5, push rod 16 also can become whole with right yoke plate 23.

The utility model is simple in structure, and is easy to make, and material is not had specific (special) requirements, can be widely used in splicing sleeve, the strain insulator pipe.

Claims

1, a kind of electrical lead hydraulic joint comprises body, it is characterized in that in the inner chamber (6) of body (10) hydraulic pressure push-plate (7) being set, and offers push arm notch (11) on the housing of body (10).
