Description
Technical Field
The utility model relates to an urban rail contact net system technical field, in particular to quick earthing device of rigidity contact net busbar.
Background
In the power failure maintenance process of a rigid contact network system in the subway industry, a grounding wire is connected with a contact network through a fixed bus grounding hanging ring, each rigid contact network anchor section is provided with one bus grounding hanging ring based on the influence of construction cost factors, and when the contact network is required to stop power to hang the grounding wire, operation operators hang the grounding wire on the fixed grounding hanging ring, so that the method is single, the limitation is high, the operation time and labor are wasted, and the emergency repair is inconvenient. Especially in the emergency repair process, the emergency repair recovery time efficiency is greatly reduced, and the emergency repair is not facilitated.
The traditional rigid contact net grounding wire mainly comprises a grounding shoe, a wire end clamp, an insulating rod, a plurality of strands of bare annealed copper wires, a power connection end clamp and the like. The wire end clamp is a clamp connected to the grounding net or the grounding end, and a wire to be grounded is clamped in the wire clamp by spring pressure through the spring tongue piece, so that the grounding wire is reliably connected with the wire; the short circuit line is a plurality of strands of bare annealed copper wires for grounding, and a heat-shrinkable silicone rubber sleeve is sleeved outside and fastened with a wire end clamp and a grounding end clamp of the lead respectively by screws; the grounding operating rod is an insulating handle arranged on a wire end clamp and used for hanging and assembling and disassembling the wire clamp. The tongue-shaped compression type grounding wire is convenient to use and wide in application. However, the ground wire is unstable in connection due to the self structure of the ground wire when hung on a suspended vertical wire or in strong wind, so that the wire is easy to slip off from a wire clamp, the operation risk of maintainers is increased, and the production requirement can not be well met.
Disclosure of Invention
In order to overcome the not enough of above-mentioned prior art, the utility model aims to provide a quick earthing device of rigidity contact net busbar, the device can realize that the rigidity contact net does not rely on the earth clamp to realize quick ground connection function, has saved the cost expense of ground connection link when setting up the rigidity contact net, under emergency such as salvagees, can accomplish fast and test electric ground connection, improves the flexibility and the convenience that the ground wire connects to hang greatly, improves and overhauls and salvagees efficiency.
A quick grounding device for a busbar of a rigid contact network comprises a limiting bolt 1, a clamping block 2, a limiting slideway 3, a lifting adjusting screw rod 4 and an insulating rod connector 5;
spacing slide 3 sets up at C type mould inboard, set up fixture block 2 on the spacing slide 3, 2 bottoms of fixture block set up lift adjusting screw 4, and lift adjusting screw 4 passes C type mould bottom and is connected with insulator spindle connector 5, and C type mould top position sets up spacing bolt 1.
The limiting slide 3 and the C-shaped die are of an integrated structure.
The insulating rod connector 5 is connected with the insulating rod.
And a bottom hole is formed in the side surface of the C-shaped die and communicated with a bolt-connected grounding wire.
The utility model has the advantages that:
the device improves the suitability and the convenience of traditional earth connection fastener, simultaneously, and operation operating personnel can realize under emergent condition that the earth connection need not to look for the ground connection link and install with the busbar fast in fault point both sides, can hang the usefulness promptly when the earth connection is hung, demolish the convenience, can optimize the old-fashioned flow of rigidity contact net electricity testing ground connection, can improve the operating efficiency again.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1: a quick grounding device for a busbar of a rigid contact network comprises a limiting bolt 1, a clamping block 2, a limiting slideway 3, a lifting adjusting screw rod 4 and an insulating rod connector 5;
spacing slide 3 sets up at C type mould inboard, set up fixture block 2 on the spacing slide 3, 2 bottoms of fixture block set up lift adjusting screw 4, and lift adjusting screw 4 passes C type mould bottom and is connected with insulator spindle connector 5, and C type mould top position sets up spacing bolt 1, prevents that C type mould from turning to drop when rotating insulator spindle connector 5.
The limiting slide 3 and the C-shaped die are of an integrated structure.
The limiting bolt 1 plays a role in fixing and is installed on the busbar to prevent the die from falling off when rotating.
The clamping block 2 prevents the clamping block 2 from turning when the lifting adjusting screw rod 4 rotates.
The limiting slide rail 3 is combined with the clamping block 2 for use, and the clamping block 2 is prevented from turning when lifted.
The insulating rod connector 5 is connected with the insulating rod.
And a bottom hole is formed in the side surface of the C-shaped die and communicated with a bolt-connected grounding wire.
The utility model discloses realize that the earth connection need not to utilize the ground connection link to install with the busbar fast in the fault point both sides, can hang promptly when the earth connection is hung and use, demolish the convenience, improved the convenience greatly. The utility model discloses need not to set up busbar ground connection link, practiced thrift the construction cost in the construction installation. The utility model discloses hang the usefulness promptly when realizing that the ground wire connects to hang, do not rely on the quick ground connection function that ground clip realized quick ground connection.
The utility model discloses a theory of operation:
the utility model discloses in, 5 lift adjusting screw 4 of lift adjusting screw 4 clockwise turning insulator spindle connector rises, and the tight busbar of fixture block 2 clamp, 5 lift adjusting screw 4 of anticlockwise turning insulator spindle connector descend, and the busbar is loosened to fixture block 2.
