A kind of portable power construction earthing device
 
Technical field
The present invention relates to the specific purpose tool that uses in a kind of electric power overhaul and the work progress, specifically is a kind of portable power construction earthing device.
Background technology
Earth connection is when unexpectedly voltage occurring on equipment that has had a power failure and circuit, guarantees the important tool of staff's safety.Portable short circuit earthing device is a kind of temporary grounding device commonly used in electric power overhaul and the work progress, its effect is when circuit and power transformation construction, be used to prevent that equipment, circuit from sending a telegram here, closing on electrified body suddenly and producing electrostatic induction and get an electric shock, perhaps drain residual charge during false switching, to guarantee the personal safety of staff in maintenance process.
Existing portable short circuit earthing device mainly is made up of insulating bar, ground connection head, the ground connection head adopts the fine aluminum alloy die cast, the intensity height, make the unsuitable oxidation in surface through surface treatment again, hook stick is refined into color tube with import epoxy resin, good insulation preformance, intensity height, in light weight, in bright gay color, smooth in appearance.At present the ground connection head mainly contains three kinds: the plain end screw formula, round mouth is spiral and the dual spring compression type.These three kinds of ground connection heads exist following shortcoming: 1. the plain end screw formula is puted forth effort when compressing along with spiral owing to the contact position place in screwing process gradually, and lead easily is shifted, and causes clamping place poor reliability; 2. dual spring compression type and spiral when blocking lead all exists and can't compress lead, causes contact-making surface not enough easily, and short circuit current is not up to standard, easily glimmers; 3. owing to the direction of ground connection head is fixed, can not operate by any direction, can't satisfy the multidirectional operational requirements of switch cubicle, in practice process, often take place because operator orientation of living in and electric wire are not in vertical position, thinking stablely when catching on electric wire when hand-held 2 meters long earthing device, is the unusual difficult work of part; 4. because changing, direction of operating cause effective insulation distance not enough; 5. 220kv and above supertension line ground connection are installed especially difficulty, and potential safety hazard is very serious.
For solving the problem of above existence, be necessary to develop a kind of ground connection head of can universal operation and can compress automatically, can save the activity duration like this, reduce operating personnel's labour intensity, full guarantee operating personnel's personal safety.
Summary of the invention
Technical problem to be solved by this invention provides a kind of can the operation in any direction, and the universal earth connection of the portable hydraulic that compresses automatically.
Portable power of the present invention construction earthing device comprises insulating bar and ground connection two parts, adopts universal joint to be connected between described ground connection head and the insulating bar.
Above-mentioned universal joint comprises the ballhead that is fixed on the insulating bar top, a ground connection bottom is provided with the hemisphere draw-in groove with the ballhead coupling, ballhead is installed in the hemisphere draw-in groove and can be provided with the screw that penetrates the hemisphere draw-in groove and be used for fixing ballhead on the ground connection head corresponding with hemisphere draw-in groove position therein along unwrapping wire rotation arbitrarily.
As improvement of the present invention, described ground connection head comprises the shank that is connected with insulating bar, the fixedly bayonet socket that crosses out by the shank top, and the movable bayonet socket that is oppositely arranged with fixing bayonet socket, and an end of this activity bayonet socket is slidingly arranged in shank; Be provided with hydraulic actuator in movable bayonet socket bottom, the shank of the urceolus of this hydraulic actuator and ground connection head is fixed, and hydraulic stem is connected with movable bayonet socket bottom, on the hydraulic handle of the insulating bar bottom that the hydraulic oil pipe of hydraulic actuator is connected to.
As a further improvement on the present invention, be provided with a groove on the clamping face of fixedly bayonet socket and movable bayonet socket, be provided with a holding piece of being made by elastomeric material on groove, holding piece is connected with the clamping face of bayonet socket by spring.
Shank at the ground connection head is provided with the retractable member that can regulate length, can regulate the active length of ground connection head, makes device have versatility.
The present invention is by adopting universal joint to be connected between ground connection head and the insulating bar, can be grounded the arbitrarily angled variation of head, during use by the operator according to the position judgment of self and electric wire and adjust the angle of ground connection head, tighten the screws gets final product when being adjusted to proper angle, realized the enterprising line operate of any direction, by using hydraulic system, solved prior art by displacement that manpower rotates or spring compression causes and the problem that can't compress.In addition, on the clamping face of bayonet socket, groove is set, the holding piece of being made by elastomeric material is installed on groove.When not stressed at ordinary times, holding piece is a straightened condition, and when hanging on the line, along with hydraulic pressure compresses, holding piece is compacted, makes spring compression, and the effect by spring and groove makes the holding piece both sides intermediate recess that raises up, thereby packs tightly lead, prevents that lead from skidding off.
