Description

Easily hang earth clamp of tearing open

Technical Field

The utility model relates to an earth connection fastener technical field, concretely relates to easily hang earth connection fastener of tearing open.

Background

When high-voltage line maintenance work is carried out, in order to ensure personnel safety, a line to be maintained needs to be reliably grounded; the existing grounding wire clamps comprise two types, one type is an aluminum plate opening lapping type grounding wire head, and the defects of the existing grounding wire clamp is that the connection is not firm, the existing grounding wire clamp is easy to fall off, so that the grounding wire protection of an operator is lost, and in addition, the grounding wire needs to be wound and bound for reliable installation during installation, so that the safety regulation is violated; the other type is a clamp type grounding wire head, the grounding wire head needs to be aligned and repeatedly and forcibly pulled during installation, and needs to be greatly pulled to be separated during removal, so that time and labor are wasted, and certain safety risk is brought to operating personnel.

Detailed Description

Example 1, as shown: a grounding wire clamp easy to hang and detach comprises a U-shaped wire clamp (1), wherein a groove (2) is formed in the inner surface of the U-shaped wire clamp (1), a blocking piece (3) is movably hinged to the middle position inside the groove (2), the middle of the blocking piece (3) is movably hinged to one end of each of two telescopic springs (4), the other end of each of the two telescopic springs (4) is hinged to the inside of the groove (2), and the hinged positions of the two telescopic springs are located above and below the blocking piece (3) respectively; the outer surface arc top position of U type wire clamp (1) is equipped with pull ring (5) through threaded connection, uses when pull ring (5) are used for taking off the ground wire.

Furthermore, when the two telescopic springs (4) are movably hinged with the middle of the separation blade (3), one of the two telescopic springs is located on the front face of the separation blade (3), the other of the two telescopic springs is located on the back face of the separation blade (3), when the grounding wire clamp is disassembled and assembled, one telescopic spring (4) can stretch, the other telescopic spring (4) can contract, and the two telescopic springs (4) cannot influence each other in the hinged mode when working.

Furthermore, the hook head of the U-shaped wire clamp (1) is designed to be arc-shaped, a main wire can be easily clamped into the U-shaped wire clamp (1) when the ground wire is hung, the wiring bolts (6) are arranged on the outer side of the hook handle of the U-shaped wire clamp (1), the two wiring bolts (6) are arranged on the upper and lower positions of the stroke, and the ground wire can be better fixed on the U-shaped wire clamp (1) through the design of the two wiring bolts (6).

Furthermore, U-shaped line clamp (1), separation blade (3) and pull ring (5) are aluminum alloy material, and aluminum alloy material is light and handy and durable, can not corrode, has prolonged this earth connection fastener's life.

The utility model discloses a use method and theory of operation: on the line maintenance site, a rope is tied on a pull ring of the ground wire clamp, the other end of the rope is tied on a safety belt of an operator, the ground wire is fixedly connected by utilizing two wiring bolts, then the operator climbs a power line tower, and after the ground wire reaches the top of the tower, a clamping opening of a U-shaped wire clamp is upwards hooked from the lower side of a power transmission line when the operator holds the ground wire, a separation blade moves towards the inside of the U-shaped wire clamp under the pressure action of the power transmission line, after the power transmission line is positioned and moved to enter an area defined by the U-shaped wire clamp and the separation blade, the separation blade resets under the action of a telescopic spring, the ground wire is loosened at the moment, and the hanging of the ground wire is completed; after line maintenance is finished and when the ground wire needs to be disconnected, an operator only needs to pull the rope upwards to separate the ground wire clamp from the power transmission line; the utility model discloses when overhauing to the circuit more than 110kV very much, under the condition that appurtenance (can't deliver higher high altitude with the earth connection fastener if the insulator spindle) can't be used, the operation personnel need carry out hanging of earth connection in the high altitude and tear the during operation open, adopt the utility model discloses labour saving and time saving safe and reliable
