Fixed connection, the second bolt can directly with first after after fishplate bar, second fishplate bar screw thread coordinate, nut can also be aided with to be fixed
Connection.
The cross level angle plate is provided with some with the one-to-one threading hole 11a of screwed hole, and each threading hole is along cross level angle plate length
Direction is equally spaced, and each screwed hole is equally spaced along vertical angle plate length direction.Can rationally be ensured safety distance, and effectively utilize sky
Between.
Fishplate bar is arranged vertically after fishplate bar and second after fishplate bar, first before fishplate bar, second before described first, fishplate bar before first
With second before fishplate bar be affixed, fishplate bar is followed by being affixed with second after first.
Preceding half hoop is docked with rear half hoop, forms the anchor ear of a class ring-type, and anchor ear can be fixed on utility poles, so as to real
The fixation of existing galvanized angle iron, on galvanized angle iron, each screwed hole can be used for connection arrester (will be kept away by screw, bolt etc.
Thunder device is fixed, and screw, bolt etc. are connected with screwed hole), each threading hole can be used for fixing arrester lead.Whole zinc-plated angle
The position of iron can be adjusted, rationally to be avoided to the other structures on electric pole.When adjusting galvanized angle iron, locking screw is unclamped
Nail, allow galvanized angle iron be moved to needed for behind position, then with lock-screw compress galvanized angle iron (vertical angle plate).
Embodiment 2：The basic structure of the present embodiment is with embodiment with embodiment 1, its difference, such as Fig. 4 extremely
Shown in Fig. 6, the lock-screw number is two, and lock-screw axis is perpendicular to vertical angle plate.
If the inner ring surface of the anchor ear is provided with dry contact bar 5, contact rod axis are vertical, and each contact bar is circumferentially equal along anchor ear
Even distribution, contact bar number are at least 6.Carry out contacting the requirement for reducing the anchor ear accuracy of manufacture using bar and electric pole is contacted
(if anchor ear directly contacts connection with electric pole, needs anchor ear size and electric pole matching degree higher, but this is to be difficult in practice
Reach because electric pole surface is inherently not necessarily regular, it has a projection and sunk part, and using contact bar come
Contacted with electric pole, then contact bar can be allowed to avoid the projection on electric pole surface, so as to after anchor ear is pinned, firmly compress
Electric pole, realize and firm be effectively connected).
Fishplate bar is provided with defrosting cylinder body 6 before described second, is provided with defrosting cylinder body and is slidingly sealed cooperation with defrosting cylinder body
Defrosting piston 61, defrosting piston is by the defrosting air cavity 6b that defrosting cylinder interior is separated into defrosting oil pocket 6a and is in communication with the outside, solution
Frozen oil intracavitary is provided with returning spring 62, returning spring one end connection defrosting piston, returning spring other end connection defrosting cylinder body, solution
Freeze on piston and be provided through the piston rod 63 of defrosting air cavity；Hemizonid is provided with internal oil channel 71 afterwards, some and the first semi-ring slides
Seal the defrosting bar 72 coordinated and some and defrosting bar reels spring 73 correspondingly, defrosting bar one end is for contact wire
Top pressure end, the locating rod other end is that the bar that is in internal oil channel is inner, reels spring and is in internal oil channel, reels spring one end
The bar of the corresponding locating rod of connection is inner, and hemizonid after the spring other end of putting away sports equipment connection, internal oil channel is connected by oil pipe and defrosting oil pocket
Logical, the first bolt includes stud section 34a and head 34b, and fishplate bar is in after head and first between fishplate bar, in stud section before first
Provided with the platen 341 for pressing perpendicular piston rod, platen and stud section are coaxially connected, are filled in defrosting oil pocket, oil pipe and internal oil channel
Full hydraulic oil.

Touch panel is in disk form, and spacing contact plate and piston rod are coaxially arranged, and spacing contact plate is provided with bullet towards the surface of platen side
Property pad, it is spacing contact board diameter be more than diameter of piston rod.Platen is no longer directly pressed to piston rod, but pressure is acted on
It on cushion on spacing contact plate, can effectively increase contact area, both avoid rigid friction, reduce spacing contact plate etc.
The possibility of structural damage, and piston rod is protected (if platen direct friction piston rod, piston rod easily snap off,
After having cushion, equivalent to having buffering and protection, piston rod is just not easily broken).In addition, spacing contact plate is also one
Position limiting structure, after spacing contact plate contacts defrosting cylinder body, platen can not continue to push piston rod into defrosting cylinder body, so as to
The excessive pushing piston bar of platen can be prevented, so as to which the structures such as the cylinder body that thaws, returning spring are effectively protected.
The defrosting piston glide direction is replied parallel to the first bolt axis, piston rod parallel to the first bolt axis
Axle of spring is between platen and defrosting oil pocket parallel to the first bolt axis, defrosting air cavity
The defrosting bar glide direction is horizontal, and the axis of any defrosting bar intersects with anchor ear axis, the defrosting bar number
Mesh is 2 to 8.
In the present embodiment, when needing to dismantle of the invention, if under ice and snow weather, hold between anchor ear inner ring surface and electric pole
Easily freeze and (have ice cube, ice sheet), the ice cube outside anchor ear, it is easy to regard to that can break into pieces, and the ice cube within anchor ear inner ring surface, then
More difficult removal, so just it is unfavorable for the dismounting of the present invention.In the present embodiment, it is necessary to when dismantling the present invention, if anchor ear inner ring surface
Freezed between electric pole, then the first bolt of turn first, the first bolt can be made towards defrosting cylinder body before the first bolt is unloaded
It is mobile, after the first bolt band dynamic pressure disk presses spacing contact plate, drive piston rod, defrosting piston to move, one in defrosting oil pocket
Section hydraulic oil enters internal oil channel through oil pipe, and so as to which the bar that thaws is displaced outwardly, reels spring elongation, defrosting bar enters anchor ear and electricity
Space between line bar, ice cube therebetween is extruded, crushes ice cube, then can screwed out, unload the first bolt, now
Easily anchor ear can be allowed to be separated with electric pole.And in the case where reeling spring effect, each structure at defrosting cylinder body can automatically reset.
