Description

A kind of earth connection
Technical field
The present invention relates to ultra-high-tension power transmission line inspection and maintenance technical field, be specifically related to a kind of earth connection.
Background technology
Earth connection is high-voltage grounding wire particularly, is the important tool in order to ensure staff when unexpectedly there is voltage on the equipment had a power failure and circuit, is to close on for preventing the use ensureing safety when electrified body produces electrostatic induction electric shock or false switching.
In the prior art, the earth connection of use all adopts hook to be connected with insulating bar is affixed, or is directly that hook is one-body molded with bar, forms insulating bar at outer layer covers one deck insulating material of bar, and the earth connection of these structures is all generally in fixing linear.When strain rod tower and traditional electric pole electrical verification ground connection, staff due to health be in quite high tower top position, then the hook of the earth connection of this fixed structure is suspended on power transmission line, because the position of getting on is different at every turn, so when tower top operation, mode and the direction of its hook all can change to some extent, but the hook of earth connection is but constant all the time, so hang up very inconvenient, usually need staff to lean to one side or the action such as to be moved in high-altitude, there is great potential safety hazard.In addition, the earth connection of this fixed structure due to the flexibility of hook cannot be changed, also make hook hang firm not, easily fall down because of wind or shake.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, a kind of earth connection is provided, with being suspended on power transmission line of solving that earth connection in prior art can easily be not firm.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: a kind of earth connection, comprise insulating bar, hook and ground lead, one end conduction of described ground lead is fixedly connected on hook, described hook is arranged on the top of insulating bar, the top of described hook and insulating bar is hinged by connecting pin, positioner is provided with between hook and the top of insulating bar, described positioner is made up of the retaining groove at insulating bar top and the scalable jacking block be arranged on bottom hook, Compress Spring is provided with between described scalable jacking block and hook bottom groove, scalable jacking block presses fixing by Compress Spring and retaining groove.
Better technique effect is played: further technical scheme is one end connection insulating bar and the hook of above-mentioned connecting pin, and the other end fixes positioner for making the present invention.
Further technical scheme is two ends connection insulating bar and the hook of above-mentioned connecting pin, and positioner is fixed at middle part.
Further technical scheme is above-mentioned positioner is be made up of the scalable jacking block of the retaining groove and insulating bar top that are arranged on hook bottom, be provided with Compress Spring between described scalable jacking block and insulating bar top groove, scalable jacking block presses fixing by Compress Spring and retaining groove mutually.
Further technical scheme is that above-mentioned retaining groove has two or more, comprises two, is evenly distributed in around described connecting pin.
Further technical scheme is that above-mentioned retaining groove has five, and centerlines is each other 45 degree.
Compared with prior art, the invention has the beneficial effects as follows: hook has rotating function, thus make worker when using earth connection, do not need to lean to one side or the action of movement, because hook can do the rotation of multiple angles, and left or the different angles that turn right, as 90 degree, the angle place of 45 degree or 0 degree is fixed automatically, such user can need according to it selection hook being made to many grades of rotational angles in use in advance, therefore improve Personal Safety, improve suspension efficiency, hang more convenient simultaneously, hang reliable in action, improve sprung mass, be specially adapted in the common employing of power supply department, there is good promotion prospect.
