Abstract

A cable safe puncture awl grounding device comprises a hydraulic cylinder, a puncture awl, a cable fixing fitting, and a grounding device. The hydraulic cylinder is double-acting hydraulic cylinder. A choke is connected to a double-acting hydraulic pump through an oil pipe. The fixing fitting has an adjusting device and a cable mounting and fixing device. The puncture movement and the repositioning movement are completed through a double-acting hydraulic system to increase repositioning force, shorten hydraulic cylinder and reduce product self weight. The cable mounting and fixing device is employed to reinforce device positioning on a cable, and be convenient for worker operation. A puncture awl guide device is increased to be stably and reliably puncture the puncture awl into the cable, maintain normal operation of a cylinder piston, and improve device service life. A pin type stroke adjusting device is employed to shorten operation time and improve working efficiency.

Description

Cable security thorn tapered joint ground device
Technical field
The utility model relates to cuts a kind of device that changes indispensability in the cable line construction, the cable security thorn tapered joint ground device that particularly a kind of bidirectional hydraulic drives
Background technology
Existing cutting changes in the cable line construction, is manually with sledgehammer the thorn awl of tape insulation bar to be squeezed into cable in the past, makes thorn awl point and cable conductor short circuit, with the cable artificial ground.After no abnormal phenomenon, change construction just can cut.
Chinese patent ZL99244025.4 has reported a kind of " cable security earthing device, ", and the patentee is Beijing Power Supply Engineering Corp..This patent makes cable thorn tapered joint ground, easy to operate, efficient, the safety of this device by parts such as hydraulic jacks.But this device remains in some shortcomings, and for example, the original device hydraulic cylinder adopts the spring return, owing to be subjected to structural limitations, big elastic spring can not be set, piston return difficulty etc.
Summary of the invention
The purpose of this utility model provides a kind of cable security thorn tapered joint ground device, and this device makes the thorn awl stablize, thrust reliably cable, guarantees the operate as normal of oil cylinder piston, in the useful life of improving equipment, increases work efficiency.
For achieving the above object, the utility model by the following technical solutions:
This cable security thorn tapered joint ground device, it comprises: hydraulic jack, thorn awl, cable be gold utensil, earthing device fixedly, and it is characterized in that: described hydraulic jack adopts double acting hydraulic cylinder, and oil nozzle is connected with the double acting hydraulic pump by oil pipe; Fixedly gold utensil is provided with adjusting device, and cable clamping fixture.
Described gold utensil adjusting device comprises: be positioned at the adjustable plate on the arm-tie, have on the adjustable plate for the pin-and-hole of regulating usefulness, an end of adjustable plate is by the base of screw, nut connection gold utensil, and the other end of adjustable plate connects the V-clevis of gold utensil with latch
The utility model has the advantages that:
1, owing to adopted the double acting oil hydraulic system, thrusts action and finish by oil hydraulic system, increased returning place force, shortened hydraulic cylinder, alleviate the deadweight of product with revert action.
2, owing to adopt cable clamping fixture, strengthen the location of device on cable, made things convenient for the workman to operate.
3, increased thorn awl guider, made the thorn awl stablize, thrust cable reliably, and guaranteed the normal running of oil cylinder piston, the useful life of improving equipment.
4, adopt the stroke adjusting device (press the diameter of cable, regulate the latch position) of bolt-type, shorten the operating time, increase work efficiency.
5, adopted insulation property oil pipe preferably, operated safer.
Description of drawings
Fig. 1: be front view of the present utility model
Fig. 2: be the vertical view of Fig. 1
Among Fig. 1, Fig. 2,1 is oil cylinder, and 2 is oil nozzle, and 5 is piston, and 10 is the cylinder seat, and 3,6,9 is back-up ring among the figure, and 4,7,8 is sealing ring.
29 are the thorn awl, and the thorn awl adopts prismatic awl point, is convenient to thrust cable, and thorn body and function taper shape is easy to rotate from cable and extracts.There is a screw at the cone rear portion, and in order to connection earth connection 11, the thorn awl adopts bolt-type to be connected with hydraulic cylinder piston, can eliminate torque suffered when stinging the bore spine cable, connection, easy accessibility.
On the cylinder seat, connect and fix the arm-tie 19 of two symmetries with screw 28, in order to adapt to the cable grounding construction of different size, be connected with adjustable plate 22 on the arm-tie, have on the adjustable plate for the pin-and-hole of regulating usefulness, one end of adjustable plate is by screw 26, nut 25, and packing ring 24, spring washer 23 connects the base 27 of gold utensil, the other end of adjustable plate connects the V-clevis of gold utensil with latch 20, deviate from for preventing latch, the other end of latch is connected with latch jam plate 33 and latch rivet 34, among the figure, 31,32 is respectively key chain loop, key chain, this chain are connected (being provided with for preventing that latch from losing) with pin 20, the other end of this chain is connected on the bearing pin 15.
The front portion of V-clevis is a guide pad 12, is lined with lining in the guide pad, and the thorn awl is positioned at lining, makes the thorn awl stablize, thrust reliably cable.
Be provided with cable clamping fixture on the arm-tie in the V-clevis outside, this device comprises: press cable handle 13, and handle cam 14, this presses the cable handle to be connected with spring straight pin 18 with the handle cam, and 16 for preventing a shaft block ring that skids off.When needing to clamp, turning handle, handle drives the cam displacement, compresses V-clevis, and cable is compressed.
This device adopts double loop superhigh pressure insulation rubber tube (market is on sale), can be used for 220 kilovolts and following cable and cuts and change construction.
Method of operation: cable fixedly gold utensil with cable fixing after, control manual double acting oil pump, utilize hydraulic pressure mechanism that the taper earth rod is stung cable insulation until cable conductor, make between through-flow conductor and the metallic sheath and form short circuit, and external earth connection on instrument makes cable conductor ground connection stably, reliably and safely.
