Embodiment
Accompanying drawing is a kind of most preferred embodiment of steel pipe scaffold Special grounding device, new to this practicality below in conjunction with the accompanying drawings
The further details of explanation of type.
A kind of steel pipe scaffold Special grounding device, including ground wire 2.Described one end of ground wire 2 is electrically connected with ground connection
Pincers 1, the described other end of ground wire 2 is electrically connected with drop bar 3.Described ground connection pincers 1 include jaw 1a and handle 1b, handle
1b is surrounded by electro-insulating rubber, avoid worker install earthing or grounding means when electric shock phenomenon generation.Set on the inside of described jaw 1a
There is zigzag puncture 1c, when ground connection pincers 1 are stuck on the frame pipe of scaffold, puncturing 1c can increase between ground connection pincers 1 and frame pipe
Frictional force, prevent ground connection pincers 1 use during come off.Described jaw 1a is provided with connecting shaft 1d, institute with handle 1b junctions
The connecting shaft outer sheath stated is equipped with torsion spring 1e.Torsion spring (Torsion Spring) is the best of variant spring, by single torsion spring to double
Torsion spring abnormity torsion spring, or even the deformation of various torsion bars, obtain and be molded according to design, two external parts are respectively protruding into two to torsion spring 1e up and down
In handle 1b, jaw 1a is kept to be in normally off.Described jaw 1a is used for the frame pipe for being connected to steel pipe scaffold.
The described lower end of drop bar 3 is provided with tapered portion 3a, and the described bottom of drop bar 3 is inserted in soil by tapered portion 3a
Portion, it is provided with inside the first chute 3a1, the first described chute 3a1 on described drop bar 3 and is provided with positioned at tapered portion 3a top
Lower magnet ring 3b, the top on described drop bar 3 positioned at the first chute 3a1 are provided with the second chute 3a2, the second described chute
Upper magnetic ring 3c is provided with inside 3a2, the described upper end of drop bar 3 is provided with the water tank 3d concordant with the upper surface of drop bar 3, described water
Case 3d upper ends are provided with plus water plug 3e, and plane is to having under spring strut 3d1, described water tank 3d on described water tank 3d inside
Plane is provided with plane on weeper 3d2, described upper magnetic ring 3c and is provided with the push rod 3c1 that discharges water upwards, and described discharges water on push rod 3c1
End is provided with circular cone 3c2, and thrust spring 3f, described circular cone are provided between described circular cone 3c2 and spring strut 3d1
3c2 is inside weeper 3d2.Upper magnetic ring 3c upper plane is back taper, inboard between circular cone 3c2 and weeper 3d2
Mating surface be along the inclined-plane inclined axially outward of drop bar 3, the upper planes of described lower magnet ring 3b and upper magnetic ring 3c lower planes
Magnetic pole is identical.The most strong part of magnetic is magnetic pole on magnet.Magnetic field around magnet be present, the interaction between magnet is exactly with magnetic
Field is as medium.No matter how small one magnet is two magnetic poles, and the magnet that can freely rotate in the horizontal plane is static
When always magnetic pole point to south, another magnetic pole points to the north, and energized south is called the South Pole (S poles), points to being called for north
The arctic (N poles).Between the phenomenon that like pole is mutually exclusive, opposite pole attracts each other is presented.On lower magnet ring 3b plane with it is upper
The magnetic pole of magnet ring 3c lower planes is identical, and when magnet ring 3b is moved up instantly, because like pole is mutually exclusive, upper magnetic ring 3c also can
With moving up.
Ground connection refers to the outer conductive part of the neutral point of power system and electric device, the exposed conductive part of electrical equipment and device
Lease making is connected by conductor with the earth, can be divided into working earthing, lightning protection and protective grounding.Described one end of ground wire 2 point
Upper and lower two solder joints point is welded on the outside of jaw 1a, and the described other end of ground wire 2 is fixed on drop bar 3 on second chute 3a2
Side.It is grounded pincers 1 to be connected on the frame pipe of scaffold, ground connection pincers 1 are connected by ground wire 2 with drop bar 3, constitute one completely
Protective grounding circuit.Protective grounding is in order to prevent equipment from jeopardizing ground connection set by personal safety because insulation damages are powered, such as
Metal shell, steel reinforced concrete pole and the metal shaft tower of power equipment.Protective grounding is simply in the case of apparatus insulated damage
Just have electric current to flow through, its value can be in interior variation in a big way.
In use, first by the tapered portion 3a of drop bar 3 down, inserting below ground certain depth, then ground connection pincers 1 are stuck in
On scaffold frame pipe, each steel pipe scaffold respectively will arrange that a steel pipe scaffold is special on two frame pipes of diagonal
Use earthing or grounding means.The structure of steel pipe scaffold is not destroyed while function is grounded, it is ensured that the intensity of scaffold, improve
Scaffold it is safe to use, better than existing three kinds of scaffold earthing modes.The ground connection side of ground steel pipe scaffold at present
Formula has three kinds：1st, independent grounding is not done, using contact of the steel pipe with ground, is grounded as support body.2nd, wound form, due on support body
There is no special earth point, so ground wire can only be wrapped on frame pipe.3rd, welding or bolt connection, after being punched on frame pipe.
Problems be present in these three earthing modes：The support body of independent grounding is not done, and because support body foundation soil is different, grounding resistance is not
The requirement of Regulations can be met；Wound form ground connection is insecure, and grounding resistance also is difficult to meet to require；Welding or bolt connection,
Grounding resistance disclosure satisfy that requirement, but the vibrations in drill process can destroy the stability of support body, and hole also has a strong impact on frame
The intensity of pipe.
When drop bar 3 inserts underground, the lower magnet ring 3b upward slidings in the first chute 3a1 of ground dragging, due to lower magnetic
Plane is identical with the magnetic pole of upper magnetic ring 3c phase planes on ring 3b, and lower magnet ring 3b, which is moved up, can promote upper magnetic ring 3c to move upwards, opens
Circular cone 3c2.Water droplet flows downward along the push rod 3c1 that discharges water, because upper magnetic ring 3c upper flat shape is back taper, it is ensured that water
Drop can flow after being left to upper magnetic ring 3c along under the plane phase of drop bar 3, improve the earthing effect of this patent.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Above-mentioned embodiment, in art those of ordinary skill's possessed knowledge, this reality can also not departed from
With on the premise of new objective, various changes can be made.
