Abstract
The utility model discloses a grounding wire clamp in a power transmission line. The grounding wire clamp comprises a clamping mechanism including a bottom clamping portion and a top clamping portion. The bottom clamping portion comprises a pressing plate and a crank portion. The pressing plate is coordinately connected with the crank portion through a screw rod. The crank portion is connected with the top clamping portion in a fastening manner. The lower end portion of the screw rod is equipped with a connector connected with an insulating rod. The power transmission line can be compacted and fixed between the top clamping portion and the pressing plate of the bottom clamping portion. Therefore, a phenomenon of lost connection does not generate and work efficiency is substantially increased. The width of the top clamping portion and the width of the bottom clamping portion can be adjusted according to the diameter of the power transmission line. The grounding wire clamp is easy to use.
Description
Technical field
The utility model belongs to the transmission line construction technical field, is specifically related to a kind of power transmission line ground wire wire clamp.
Background technology
Transmission line stops power transmission, when overhauling line work, must articulate earth connection.The critical component of earth connection is wire clamp, and original earthing wire clip structure is in hook, a splayed clip to be arranged, and during use, utilizes the splayed clip to carry out clamping to electric wire.The clip of this structure articulates conveniently, but clamping property is poor, easily goes offline.In the process of using, even appear at a construction location need tens times repeat to articulate earth connection, operating efficiency is reduced greatly.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of clamping firm, the power transmission line ground wire wire clamp that is not easy to go offline.
The technical solution of the utility model is as follows: a kind of power transmission line ground wire wire clamp, has clamping body, it is characterized in that: described clamping body, have lower card-tight part and upper card-tight part, described lower card-tight part has pressing plate and crank throw section, the logical screw rod of pressing plate and crank throw section are connected, and crank throw section and upper card-tight part are fastenedly connected, and described screw rod bottom has the connector that is connected with insulating bar.
Described upper card-tight part has chute, and described crank throw section upper end has hold-down bolt, and hold-down bolt is fastenedly connected described upper card-tight part and crank throw section.
The beneficial effects of the utility model: because lower card-tight part of the present utility model has spiral hold-down mechanism, power transmission line can be pressed abd fixed between the pressing plate of upper card-tight part and lower card-tight part, lost line can not occur.Owing to not needing to repeat to articulate earth connection, facilitated construction, simultaneously, also greatly improved operating efficiency.The slide way mechanism that upper card-tight part arranges can be according to the thickness of transmission of electricity wire diameter, and the width of card-tight part in adjustment uses the utility model more convenient.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of power transmission line ground wire wire clamp, has clamping body, clamping body has lower card-tight part 1 and upper card-tight part 2, lower card-tight part 1 has pressing plate 3, screw rod 5 and crank throw section 4, pressing plate 3 is connected by screw rod 5 and crank throw section 4, and crank throw section 4 is fastenedly connected with upper card-tight part 2, and the bottom of screw rod 5 has the connector 6 that matches with insulating bar.Upper card-tight part 2 has chute 7, and the upper end of crank throw section 4 has hold-down bolt 8, and hold-down bolt 8 is fastenedly connected upper card-tight part 2 and crank throw section 4.
When transmission line stops power transmission, when overhauling line work, the connector 6 of insulating bar and power transmission line ground wire wire clamp is connected, simultaneously, width in adjustment in the card-tight part bayonet socket, the thickness of itself and wire diameter is complementary, and the height in adjustment between card-tight part and lower card-tight part is slightly larger than the wire diameter of power transmission line.Lift the power transmission line ground wire wire clamp with insulating bar, power transmission line is entered on the power transmission line ground wire wire clamp between card-tight part and lower card-tight part, rotating insulated bar makes card-tight part and lower card-tight part chucking power transmission line.Then, the connector 6 of insulating bar from the power transmission line ground wire wire clamp taken off.
Claims (2)
1. power transmission line ground wire wire clamp, has clamping body, it is characterized in that: described clamping body, have lower card-tight part and upper card-tight part, described lower card-tight part has pressing plate and crank throw section, the logical screw rod of pressing plate and crank throw section are connected, and crank throw section and upper card-tight part are fastenedly connected, and described screw rod bottom has the connector that is connected with insulating bar.
2. a kind of power transmission line ground wire wire clamp as claimed in claim 1, it is characterized in that: described upper card-tight part has chute, and the upper end of described crank throw section has hold-down bolt, and hold-down bolt is fastenedly connected described upper card-tight part and crank throw section.
