Abstract
The utility model relates to a safety apparatus used for electric power construction. In order to overcome a technology problem of a grounding rod used during a current electric power construction process, the utility model provides an electric power grounding rod which comprises a metal rod. The grounding rod is characterized in that a rod body of a lower portion of the metal rod is provided with a screw thread; a top of the metal rod is provided with a handle; the handle and the metal rod body form a T shape; a wire wrapping wheel is arranged below the handle; the metal rod passes through a center shaft hole of the wire wrapping wheel and is fixed to the wire wrapping wheel through bearings of two ends of the wire wrapping wheel shaft hole; the wire wrapping wheel can freely rotate about the metal rod. The structure of the electric power grounding rod is reasonable and usage is convenient. The electric power grounding rod can be widely used in electric power construction.
Description
Technical field
The utility model relates to a kind of power construction safety device, is specifically related to one rod power ground.
Background technology
In the operation of electric operating power cut construction, must use earth connection after three-phase electricity ground connection, to construct, to prevent that in work progress, energising suddenly causes loss of life or personal injury.The way adopting is at present on three-phase line, to hang up short circuit hook, and short circuit hook adopts the electric conductors such as metal to support, and short circuit hook lower end fixed insulation rod carries out hook operation with convenient construction personnel, and short circuit hook is connected with earth rod by wire.The iron that the earth rod using is at present diameter 16MM, long 60CM, when ground connection, adopts the instruments such as iron hammer that its violence is followed closely in underground.The problem so producing is: 1, after operation, very difficult during by underground taking-up earth rod; 2, between earth rod and short circuit hook, have longer wire to be connected, in process short circuit hook being separated with earth rod and close up, wire is easily wound in one, is difficult for launching and drawing in, causes larger puzzlement to construction.
Summary of the invention
The technical problem existing for overcoming the earth rod that uses in current power construction process, the utility model provides a kind of and facilitates that earth rod is fixed, separation and wire are difficult for the rod power ground that occurs to be wound around.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: one is rod power ground, comprise a metal bar, it is characterized in that: the barred body of described metal bar bottom is threaded, the top of metal bar is provided with handle, and handle and metal barred body are T font, are provided with a reel below handle, metal bar passes the central shaft hole of reel and fixes by bearing and the reel at reel axis hole two ends, and reel can rotate freely around metal bar.
Further, the top of described reel is provided with a hanging ring, and hanging ring diameter is greater than reel top end plate diameter, between hanging ring and reel top end plate, fixes by former.
Further, fix a circle body at hanging ring outer ledge, reel stopping bar can move by easy on and off through circle body, and the top of reel stopping bar is provided with hook, and reel stopping bar can hang on handle by this hook.
After this said structure of rod employing power ground, by earth rod and the earth is fixed and the handle that only need rotate its top during by underground taking-up can be realized, having overcome existing earth rod needs the fixing technical problem of violence, can effectively prevent the infringement that violence causes earth rod when fixing simultaneously.On earth rod, increase reel and can prevent that wire from occurring being wound around agglomerating phenomenon in the time of unwrapping wire and take-up, it has effectively increased efficiency of construction.Bar structure is reasonable, easy to use power ground for this, can be widely used in power construction.
Brief description of the drawings
Accompanying drawing 1 is the utility model use status architecture schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, one is rod power ground, comprise a metal bar 1, the barred body of metal bar bottom is threaded 2, the top of metal bar is provided with handle 3, and handle 3 is T font with metal barred body, is provided with a reel 4 below handle, metal bar is fixed with reel through the central shaft hole of reel and by the bearing 5 at reel axis hole two ends, and reel 4 can rotate freely around metal bar 1.
Adopt after said structure, wire 6 is wrapped on reel 4, in the time that earth rod is fixed on large ground by needs, metal bar 1 slowly can be crept in soil by rotating handles 3, complete when overhauling, need to take out metal bar time, oppositely turning handle 3 can be screwed out metal bar 1 by the earth clock, and this structure efficiently solves traditional earth rod needs violence to fix, take out difficult technical problem.
As shown in Figure 1, when fixing after metal bar 1, because reel 4 can rotate freely around metal bar 1, therefore wire 6 can launch smoothly, rotates backward reel in the time of needs take-up.
As shown in Figure 1, one end of wire 6 and metal bar 1 are fixing, and the other end of wire and short circuit hook 7 are fixing, and short circuit hook 7 is fixing with insulating rod 8.When use, hand-held insulating rod 8 pulls wire 6 to launch, and short circuit hook 7 is hung on transmission line and can prevent that in maintenance process, unexpected power transmission causes casualties.
For convenience of short circuit hook 7 fixing with earth rod in the time not using, as shown in Figure 1, the top of reel 4 is provided with a hanging ring 9, and hanging ring 9 diameters are greater than reel top end plate diameter, pass through former 10 and fix between hanging ring 9 and reel top end plate.After wire 6 is closed on reel 4, short circuit hook 7 is hung on hanging ring 9.
Further, for freely rotating of restriction reel 4, as shown in Figure 1, fix a circle body 11 at hanging ring 9 outer ledges, reel stopping bar 12 can move by easy on and off through circle body, and the top of reel stopping bar 12 is provided with hook 13.After reel stopping bar hangs on handle 3 by this hook 13, the rotation of reel 4 is restricted, when by reel stopping bar 12 by handle 3 on separate after, reel 4 can be realized and rotating freely.
