Abstract
The utility model relates to an inner hydraulic joint for an electric power conducting wire. The existing inner hydraulic connection method is that a compression joint component part is arranged in a metal pipe body, and the two end ports of a metal joint are compressed into cones to make the metal joint to form a double head cone pipe body. A hydraulic notch is arranged on the pipe body, and a hydraulic push arm is extended into the pipe body to carry out hydraulic pressure. But the device is limited by the hydraulic notch and the push arm, so the hydraulic distance is short, and the device is not suitable for the connection of the conducting wire with a major diameter. The pipe body of the hydraulic joint is made into a single head cone, and a cone clamp is designed to clamp the single head cone. The utility model uses a hydraulic jack to directly carry out hydraulic pressure at the back end of the clamp. The utility model has the advantages of long hydraulic pressure distance, simple manufacture technology and low cost.
Description
The utility model relates to a kind of electrical lead hydraulic connecting device, specifically refers to hydraulic joint in a kind of electrical lead.
Existing electrical lead hydraulic joint (number of patent application: 98230550.8) be in the metal body, to preset parts such as aluminium pawl, steel folder, push-plate, again the metal joint two ends be pressed into cone, form double end cone body, on body, offer the push arm notch.When carrying out the electrical lead connection, lead is inserted the joint two-port, put in notch with the hydraulic pressure push arm then and carry out hydraulic pressure, though this in hydraulic joint more laborsaving than external hydraulic method, save time, but this joint also has weak point: 1, this joint will be preset at aluminium pawl, steel folder, push-plate in the body earlier, two-port with the metal body is pressed into cone shape again, manufacturing process complexity, the corresponding height of cost; 2, run into the bigger electrical lead of diameter and connect, corresponding metal body bore is big, and the hydraulic pressure required distance is long, and the hydraulic pressure notch is along with prolongation, and the distance of this double end cone hydraulic pressure is subjected to the restriction of hydraulic pressure notch and hydraulic pressure push arm, can not satisfy the needs of real work.
The purpose of this utility model is to provide that a kind of manufacturing process is simple, cost is low, the hydraulic pressure distance, can carry out the hydraulic joint that the major diameter electrical lead connects.
The utility model adopts following technical scheme, and a port of hydraulic joint body is processed into cone shape, and the another port is isometrical body, on the isometrical body screw thread is arranged, and aluminium pawl, steel folder are housed in the body.
Design anchor clamps again, the front end of anchor clamps is made into cone shape, adapt with electrical lead hydraulic joint cone, installing hydraulic means (or jack) in anchor clamps rear end is put into the anchor clamps front end with hydraulic joint, and lead inserts from the cone port, hydraulic means promotes push-plate extruded aluminium pawl, steel folder, clamping wire, the joint with two single head cones is screwed in together with tube connector then, reaches electrical lead hydraulic pressure and connects purpose.
Because this electrical lead hydraulic joint adopts the single head cone, do not need aluminium pawl, steel folder are preset in the body, when needing to connect, aluminium pawl, steel are folded up into temporarily and carry out hydraulic pressure and get final product, so the manufacture craft of hydraulic joint is simple, cost is low; Withstand on the anchor clamps with hydraulic jack aluminium pawl, steel folder are directly carried out hydraulic pressure, the restriction of not managed body fluid indent mouth and hydraulic pressure push arm, hydraulic pressure is long apart from height, the hydraulic pressure of suitable major diameter body joint.
Below in conjunction with accompanying drawing utility model is further described:
Fig. 1 is an electrical lead hydraulic joint structural representation.
Fig. 2 is two electrical lead hydraulic joint connection diagrams.
Fig. 3 is a hydraulic means master pseudosection.
Fig. 4 is a hydraulic means mansion TV structure schematic diagram.
With reference to Fig. 1, Fig. 2, one port of the body 2 of electrical lead hydraulic joint is processed into cone, the another port is isometrical body, on its isometrical body screw thread 7 is arranged, when electrical lead hydraulic pressure connects, with aluminium pawl 4, steel folder 5, put into body 2, electrical lead 1 is from cone port insertion tube body 2, and the front end of lead 1 is peelled off the aluminium thigh and exposed steel core 6, steel folder 5 is clamped steel core 6, aluminium pawl 4 is the semicircle wedge shape, near the inwall of body 2 and block lead 1 and steel folder 5, because body 2 ports are cone, when aluminium pawl 4, when steel folder 5 is squeezed, the aluminium pawl, the reach of steel folder, wire bushing 3 parts are extruded outside the body 2, and the aluminium tooth on the aluminium pawl 4 holds on to lead 1 and steel folder 5, steel folder 5 is tightly clamped steel core 6, make aluminium pawl 4, steel folder 5, lead 1 becomes an integral body, then the body 2 usefulness tube connectors 8 of two single head cones is tightened, and reaches the connection purpose.
With reference to Fig. 3, Fig. 4, hydraulic means are by anchor clamps 11, and hydraulic jack 12 is formed, the front port of anchor clamps 11 is a cone, adapt with hydraulic joint body 2 cone ports, the rear end of anchor clamps 11 is isometrical bodys, and the two-port center is on same axis, hydraulic jack 12 devices are in the rear end of anchor clamps 11, when needing hydraulic pressure to connect, the body 2 of putting into lead 1 is put into the front end cone of anchor clamps 11, close with cone lid 15, bolt is by screw 13 locking cone lids 15, shake rocking arm 14, push rod 10 protracts, and promotes push-plate 9 extruded aluminium pawls 4, steel folder 5, carrying out hydraulic pressure connects, after hydraulic pressure was finished, the counter again arm 14 of swaggering withdrawed from push-plate 9, unclamp cone lid 15, take out conical tube 2.
This hydraulic joint manufacture craft is simple, and cost is low, and hydraulic jack can be fixed on the anchor clamps 11, also can adorn usefulness temporarily, and the operation of going out is convenient, can be used for the metal splicing sleeve, the strain insulator pipe.
