In the utility model, the 500 kV grounding line fixing holder possesses the advantages as following: the grounding line is wound on the roller (2) and can be expanded in sequence when in use, and no knotting or winding happens; after usage, the grounding line (9) can be wound up by the crank (4), and the grounding line (9) is not inclined to be scattered, which is easy to carry and dispose; the structure is simple; the usage is convenient; and a certain meaning is provided for enhancing the safety and normalization of the 500 kV line maintenance, improving construction conditions and raising work efficiency.

Description

500kV earth connection fixed mount

Technical field

The utility model relates to a kind of electrical apparatus, promptly a kind of 500kV earth connection fixed mount.

Background technology

Safeguarding in the installation process of 500kV circuit in order to guarantee safety, must at first be assembled ground wire, packs up ground wire when operation is accomplished again.In the past, this ground wire does not have special-purpose splendid attire instrument, can only deposit through coiling, and carries inconvenience, puts at randomly, ties a knot easily during use, twines, and disturbs carrying out smoothly of upkeep operation often.

Summary of the invention

The purpose of the utility model provide a kind of 500kV of making circuit ground wire easy to carry, avoid knotting and winding, fixed mount flexibly easy to use when putting attractive in appearance, operation.

Above-mentioned purpose is realized by following technical scheme: develop a kind of 500kV earth connection fixed mount; Be characterized in: said fixed mount has two relative insulation barriers to connect into door-shaped frame through crossbeam; Other has a rotating shaft to be installed on two insulation barriers; In the rotating shaft between two insulation barriers roller is housed, is provided with terminals in the outside of a side insulation barrier, an end of the outside rotating shaft of another insulation barrier is equipped with crank.

Said crank is made up of link arm and handle, and link arm is connected in rotating shaft one end, and handle,, is provided with and the handle snap close of clamping mutually above the insulation barrier of the rotating shaft other end in link arm upper end through the hinge of shipping and reselling on another market.

Opening one side of said two formed portals of insulation barrier is equipped with braces.

Between said braces and the insulation barrier for removably connecting.

The beneficial effect of the utility model is: earth connection is coiled on the roller, can launch successively during use, can not tie a knot or twine; Using up can be through crank with the ground wire rolling, is difficult at randomly, is easy to carry and puts; For the fail safe and the standardization that strengthen 500kV line upkeep work; Improve execution conditions, increase work efficiency, all have certain meaning.

Visible among the figure: insulation barrier 1, roller 2, rotating shaft 3, crank 4, crossbeam 5, snap close 6, earth terminal 7, bearing 8, ground wire 9, link arm 10, handle 11 ships and resell on another market 12, braces 13.

Embodiment

First kind of embodiment: like Fig. 1, shown in 2; This 500kV earth connection fixed mount is formed door-shaped frame by two relative insulation barriers 1 through crossbeam 5; Rotating shaft 3 is through between horizontal two insulation barriers 1 that are contained in framework of bearing; There is a roller 2 to be connected in the outside of rotating shaft 3 between framework, crank 4 is housed, earth terminal 7 is housed at the opposite side of framework at an end of the outside of framework rotating shaft 3.Visible in conjunction with Fig. 3, ground wire 9 is coiled in the outside of roller 2, and one of ground wire 9 is terminated at earth terminal 7.Like this, ground wire 9 can be not at random, is convenient to deposit.During work, the workman is at first with earth terminal 7 ground connection, and portable again crossbeam 5 can carry out unwrapping wire limit, limit and climb wire pole tower, carries out upkeep operation.Can certainly crossbeam 5 be articulated in people's waist, the operation that both hands can be freely.

In conjunction with Fig. 3,4 visible, crank 4 is by link arm 10, handle 11 and ship and resell on another market and 12 form, the handle 11 pin 12 rotation half cycles that can rotate.As shown in Figure 3, handle 11 changes in the framework outside, can shake roller 2, coils the operation of ground wire 9.As shown in Figure 4, on an insulation barrier 1, be provided with a snap close 6, in order to take up space less, handle 11 not the time spent can be flapped toward the framework inboard, be stuck in snap close 6 the insides.The structure of this snap close 6 can have multiple, and what this example was introduced is two indent Elastic clamping plates of erectting relatively, the clamping plate external diameter less than handle 11 suitable for reading; When handle 11 was depressed, clamping plate are compelled to be opened, and handle gets into rear plate and leans on elastic recoil; Clamping lever 11, the time spent reverse operating gets final product.

Second kind of embodiment: like Fig. 5, shown in 6, this 500kV earth connection fixed mount is identical with big of the structure of precedent, and opening one side of the door-shaped frame that is just become at two insulation barriers 1 has increased a braces 13 that has soft rope to process.Be preferably dismountable between braces 13 and the insulation barrier 1 and be connected, but for example grafting of self-locking etc.This braces 13 both had been convenient to portable, was convenient to again bear, and was very easy to use.

The third embodiment: as shown in Figure 7, the crank handle 11 of this 500kV earth connection fixed mount is shorter, and the snap close 6 that cooperates with it is located at above the insulation barrier of homonymy, and the time spent is not stuck in snap close 6 the insides and gets final product crank.When fixed mount framework broad, adopt this handle 11 relatively flexibly, structure is also compact.
