Abstract
The invention provides an electric power construction grounding device. A grounding end and an insulating operation rod are connected through a universal joint, any angle change of the grounding end can be realized, an operator is enabled to judge and adjust the angel of the grounding end in the usage process according to the positions of himself and an electric wire, and when the grounding end is adjusted to a suitable angle, the operation is completed just by tightening a screw, so that the operation in any direction is available; in addition, a hydraulic system is used, so that the problem of displacement or unavailable pressing caused by manual rotation or spring pressing in the prior art is solved. Furthermore, a groove is formed in a clamping surface of a bayonet, and a clamped sheet made of an elastic material is installed in the groove. In a usual force free case, the clamped sheet is in a flat state, and when the clamped sheet is hung on a line, the clamped sheet is tightly pressed with the effect of hydraulic pressing, a spring is pressed, and two ends of the clamped sheet go up and the middle part go down under the effects of the spring and the groove, so that a conductive wire is wrapped tightly, and the conductive wire is prevented from sliding out.

Technical field
The present invention relates to the specific purpose tool field used in electric power overhaul and work progress, more specifically, relate to a kind of power construction earthing device.
Background technology
When earth connection is to unexpectedly there is voltage on the equipment had a power failure and circuit, ensure the important tool of worker safety.Portable short-circuit earthing device is a kind of temporary earthing device conventional in electric power overhaul and work progress, its effect is when circuit and Substation construction, for preventing equipment, circuit is sent a telegram here suddenly, close on electrified body produces electrostatic induction and getting an electric shock, or drain residual charge during false switching, to guarantee the personal safety of staff in maintenance process.
Existing Portable short-circuit earthing device is primarily of insulating bar, grounding head composition, grounding head adopts fine aluminum alloy die cast, intensity is high, through surface treatment, surface should not be oxidized again, hook stick import epoxy resin is refined into color tube, good insulation preformance, intensity is high, lightweight, in bright gay color, smooth in appearance.Current grounding head mainly contains three kinds: the spiral and dual spring compression type of plain end screw type, round mouth.These three kinds of grounding heads also exist following shortcoming: 1. plain end screw type is in screwing operations, and because contact position place puts forth effort gradually along with during spiral compression, wire is easily shifted, and causes clamping place poor reliability; 2. dual spring compression type and spiral when blocking wire, all also exists and cannot compress wire, and easily cause contact-making surface inadequate, short circuit current is not up to standard, easily glimmers; 3. because the direction of grounding head is fixing, can not operate by any direction, the multidirectional operational requirements of switch cubicle cannot be met, it is not in vertical position that orientation and electric wire residing for operator often occur in practice process, when hand-held 2 meters of long earthing device think stable catch on electric wire time, be the abnormal difficult work of part; 4. because direction of operating change causes effective insulation distance inadequate; 5. 220kv and above supertension line ground connection install especially difficulty, and potential safety hazard is very serious.
Summary of the invention
The invention provides one can operate in any direction, and the power construction earthing device of automatic impaction.
In order to reach above-mentioned technique effect, technical scheme of the present invention is as follows:
A kind of power construction earthing device, comprise insulating bar and grounding head two parts, described grounding head is connected with adopting universal joint between insulating bar.
Further, universal joint comprises the ballhead being fixed on insulating bar top, grounding head bottom is provided with the hemisphere draw-in groove mated with ballhead, ballhead to be arranged in hemisphere draw-in groove and can to rotate along any direction wherein, the grounding head corresponding with hemisphere draw-in groove position is provided with penetrate hemisphere draw-in groove and for the screw of fixing ballhead.
Further, grounding head comprises the shank be connected with insulating bar, the fixing bayonet socket crossed out by shank top, and the movable bayonet be oppositely arranged with fixing bayonet socket, and one end of this movable bayonet is slidably arranged in shank; Be provided with hydraulic actuator in movable bayonet bottom, the urceolus of this hydraulic actuator and the shank of grounding head are fixed, and hydraulic stem is connected with bottom movable bayonet, in the hydraulic handle of the insulating bar bottom that the hydraulic oil pipe of hydraulic actuator is connected to.
Further, the clamping face of fixing bayonet socket and movable bayonet is provided with a groove, and groove is provided with a holding piece be made up of elastomeric material, and holding piece is connected with the clamping face of bayonet socket by spring.
Further, the retractable member that can regulate length is provided with at the shank of grounding head.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
The present invention by adopting universal joint to be connected between grounding head with insulating bar, the arbitrarily angled change of head can be grounded, the angle of grounding head is adjusted by operator according to the position judgment of self and electric wire during use, the tighten the screws when being adjusted to proper angle, achieve the enterprising line operate of any direction, by using hydraulic system, solve the displacement that prior art is rotated by manpower or spring compression causes and the problem that cannot compress.In addition, the clamping face of bayonet socket arranges groove, groove is installed the holding piece be made up of elastomeric material.Time not stressed at ordinary times, holding piece is straightened condition, and when hanging on the line, along with hydraulic compression, holding piece is compacted, makes spring compression, by the effect of spring and groove, holding piece both sides is raised up intermediate recess, thus packs tightly wire, prevent wire from skidding off.
