The transmission cross arm is compact in structure and stable and reliable in installation, and has a good shakeproof effect; and installation of a wire is facilitated.
Description
Technical field
The present invention relates to a kind of transmission of electricity cross-arm.
Background technology
The angle bar that electric pole top is laterally fixed, has porcelain vase above, is used for supporting trolley wire.The effect of cross-arm: cross-arm is ingredient important in shaft tower, its effect is used to install insulator and gold utensil, to support wire, lightning conducter, and is allowed to the safe distance certain by regulation holding.Can be divided into by purposes: straight line cross-arm；Buck arm；Strain cross arm.Can be divided into by material: iron cross arm；Porcelain pole arm；Composite insulation cross-arm.
Straight line cross-arm: only consider in the case of normally not breaking, bear vertical load and the horizontal loading of wire；Strain cross arm: bear outside wire vertically and horizontally loading, also by poor for the pulling force that bears wire；Buck arm: in addition to the vertically and horizontally loading bearing wire, also will bear bigger unilateral wire tension.According to the stressing conditions of cross-arm, the angle pole of straight line pole or less than 15 is used single cross-arm, and corner angle pole more than 15 degree, tension-resistant rod, terminal pole, branch's bar all use pair cross-arm.Cross-arm is typically mounted at masthead 300mm, and straight line cross-arm should be contained in power side, and angle pole, terminal pole, the cross-arm of branch's bar should be contained in bracing wire side.
Current existing transmission of electricity cross-arm mounting stability is the highest, easily causes structural damage when producing vibration, causes installing inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of compact conformation, installs reliable and stable, has good shockproof effect, facilitates the transmission of electricity cross-arm of the installation of electric wire.
For solving the problems referred to above, the present invention adopts the following technical scheme that a kind of transmission of electricity cross-arm, including cross bar, montant, pitman and anchor ear, described cross bar is located on montant, it is provided with connector in the middle part of described cross bar, described cross bar is connected by connector and montant are fixing, described pitman two ends are respectively arranged with the first stationary fixture and the second stationary fixture, described pitman is connected with cross bar by the first stationary fixture, described pitman is connected with montant by the second stationary fixture, in the middle part of described pitman, spring is installed, described anchor ear is located at bottom montant, it is provided with rubber ring in described anchor ear, it is provided with wire clamp on described cross bar, first pulley and the second pulley are installed in described wire clamp.
As preferably, described pitman is hinged with the first stationary fixture and the second stationary fixture respectively.
As preferably, the described first concave setting of pulley surface.
As preferably, described wire clamp is fixing with cross bar to be connected.
As preferably, described cross bar is insulation cross bar.
The invention have the benefit that the cross bar of setting is connected by connector and montant are fixing, keep compact conformation；Being provided with rubber ring in the anchor ear arranged can keep compact conformation when mounted reliable；Mounting head spring in the middle part of the pitman arranged, it is possible to eliminating the relative movement between cross bar and montant when there are vibrations, keeping good shockproof effect；Being provided with the first pulley on the wire clamp arranged and the second pulley facilitates power transmission line to be arranged on pulley, effectively protection power transmission line will not damage.

Described pitman 3 is hinged with the first stationary fixture 6 and the second stationary fixture 7 respectively, and holding pitman 3 can be movable.
The described first concave setting in pulley 11 surface, the first pulley 11 convenient transmission of electricity coil holder is above.
Described wire clamp 10 is fixing with cross bar 1 to be connected, and keeps Stability Analysis of Structures reliable.
Described cross bar 1 is insulation cross bar, it is possible to keep insulation effect good.
The invention have the benefit that the cross bar of setting is connected by connector and montant are fixing, keep compact conformation；Being provided with rubber ring in the anchor ear arranged can keep compact conformation when mounted reliable；Mounting head spring in the middle part of the pitman arranged, it is possible to eliminating the relative movement between cross bar and montant when there are vibrations, keeping good shockproof effect；Being provided with the first pulley on the wire clamp arranged and the second pulley facilitates power transmission line to be arranged on pulley, effectively protection power transmission line will not damage.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any change expected without creative work or replacement, all should contain within protection scope of the present invention.
