At present, 220, the transition joint of 110kV electric cable accessories product, in installation process, the push-and-pull of main employing manpower is aided with the nitrogen mode, be about to the end that the first end of indirect is inserted in the butt joint cable, the cavity inside to transition joint applies certain pressure nitrogen simultaneously, forms air film between transition joint inwall and cable, after two end cables connect, transition joint is withdrawn into cable butting position, two ends by manpower, protects.Because the transition joint internal diameter, causes very difficulty of push-and-pull process less than the outside diameter of cable, and the rubber electrodes of transition joint inwall is vulnerable to wearing and tearing, scratches in this process, thus the hidden danger of causing the accident.
The utility model content
Be to solve the deficiencies in the prior art, the purpose of this utility model provides a kind of predilation device of mechanization, and predilation is carried out in transition joint, simple in structure, safe and reliable, mechanization degree is high, simple to operation.
To achieve these goals, the utility model is to take following technical scheme to realize:
A kind of crosslinked cable transition joint predilation device, comprise Hydraulic Station, oil cylinder and push rod, store hydraulic oil in the described Hydraulic Station, move up and down by the described push rod of described hydraulic oil cylinder driving, it is characterized in that: on the described push rod successively socket support Hough tube, spreader cone, transition joint and pressure disc, the top of described push rod also is provided with dismountable jacking block.
Preferably, the top of described push rod is provided with and its axial perpendicular through hole, in the through hole of the described push rod of the dismountable insertion of described jacking block.
Preferably, described support Hough tube is made up of two semicircular arc covers that removably connect, and its two ends are respectively arranged with annular positioning groove.
Preferably, described spreader cone comprises conical outer surface and central through hole.
The utility model forces in the transition joint owing to adopt Hydraulic Station pulling push rod, and by the spreader cone guiding transition joint is enclosed within on the support Hough tube, and the internal diameter support of transition joint is big, realizes the predilation of transition joint; Then the transition joint of predilation is enclosed within butt joint cable one end, after cable connects mobile transition joint in place, and will support the Hough tube and extract from transition joint inside, the transition joint inwall is retracted to cable surface, easily finishes installation process.The utility model crosslinked cable transition joint predilation device, simple in structure, safe and reliable, mechanization degree is high, simple to operate, be highly suitable for 220, the on-the-spot predilation of the transition joint of 110kV crosslinked cable and installation, can effectively reduce set-up time and labour intensity, and reduce the product quality hidden danger that installation process is brought.

Embodiment
Below in conjunction with accompanying drawing the utility model specifically is described below:
As shown in Figure 1, a kind of 220,110Kv crosslinked cable transition joint predilation device comprises Hydraulic Station 1, oil cylinder 2, push rod 3, spreader cone 4, supports Hough tube 5, jacking block 6, pressure disc 11.
Store hydraulic oil in the Hydraulic Station 1, drive push rod 3 by oil cylinder 2 and move up and down, the top of push rod 3 is provided with and its axial perpendicular through hole (not shown), in the through hole of jacking block 6 dismountable insertion push rods 3.Spreader cone 4 comprises conical outer surface and central through hole.Support Hough tube 5 and be made up of two semicircular arc covers that removably connect, its two ends are respectively arranged with annular positioning groove 12, as shown in Figures 2 and 3.
Crosslinked cable transition joint predilation device of the present utility model at first starts Hydraulic Station 1 and protrudes upward the precalculated position by oil cylinder 2 driving push rods 3 in use, closes Hydraulic Station 1; Secondly, jacking block 6 is extracted from push rod 3, will be supported Hough tube 5, spreader cone 4 is set on the push rod 3 successively; Then, push rod 3 is inserted in transition joint 13, and pressure disc 11 is inserted in push rod 3 and is pressed in the upper surface of transition joint 13; At last, jacking block 6 is inserted push rods 3, and open Hydraulic Station 1, drive push rods 3 by oil cylinder 2 and move down, the jacking block 6 on the push rod 3 forces in pressure disc 11 and transition joint 13 is pressed down to be enclosed within supports on the Hough tube 5; After support Hough tube 5 upper end location notchs 12 expose product edge, stop Hydraulic Station 1.Jacking block 6 is extracted from push rod 3, taken off pressure disc 11, spreader cone 4 and transition joint 13 successively.At this moment, support the inside that Hough tube 5 has been positioned at transition joint 13, the internal diameter support of transition joint is big, finished predilation.
Through the transition joint after the expansion of the utility model predilation device, in use, at first, be set on the cable 10 being built-in with the transition joint 13 of supporting Hough tube 5; After connection is finished at the cable two ends, transition joint is withdrawn into cable butting position, two ends, protects.Use erecting tools will support Hough tube 5 then and take out, transition joint 13 internal diameters shrink the butt end of chucking cable 10, installation.
As shown in Figure 4, a kind of erecting tools is used in the utility model preferred embodiment, comprise hand-hydraulic station 7, fixedly snap ring 8 and push rod 9 movably, the end of push rod 9 be provided with and fixedly the snap ring 14 that be arranged in parallel of snap ring 8, wherein Hydraulic Station 7 can drive push rod 9 near or away from the direction of snap ring 8 on move.The cross section of snap ring 8 and snap ring 14 is semicircular ring, as shown in Figure 5.
During use, snap ring 8 is inserted in the draw-in groove that supports Hough tube 5 one ends, the snap ring 14 on the push rod 9 inserts in the draw-in groove that supports Hough tube 5 other ends; Start hand-hydraulic station 7, drive push rod 9 and drive snap ring 14, also promptly will support Hough tube 5 in the opposite direction and draw back, thereby break away from transition joint to direction motion away from snap ring 8, the transition joint inwall that taking-up is supported behind the Hough tube 5 shrinks in cable 10 surfaces, installation.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection range of the present utility model.
