Description

A kind of transmission tower cross-arm
Technical field
This utility model relates to a kind of transmission tower 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 tower cross-arm structural strength is the highest, installs inconvenience during use, and cable is mounted above the phenomenon that stress is excessive and ruptures easily occur.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, easy for installation, has good anti seismic efficiency, it is possible to effectively prevent cable stress excessive and the transmission tower cross-arm broken.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of transmission tower cross-arm, including cross-arm body, U-bolt, motion bar and base plate, the L-shaped setting in described cross-arm body cross section, installing hole and lower installing hole it is provided with on described cross-arm body, it is additionally provided with fixed plate on described cross-arm body, described U-bolt is located in installing hole, it is provided with nut on described U-bolt, described U-bolt is connected by nut and cross-arm body are fixing, described motion bar is located at below cross-arm body, the V-shaped setting of described motion bar, described base plate is located at below motion bar, described motion bar is hinged with cross-arm body and base plate respectively.
As preferably, described fixed plate is welded with cross-arm body, keeps Stability Analysis of Structures reliable.
As preferably, described fixed plate undulate is arranged, and increases structural strength, has good anti seismic efficiency.
As preferably, insulator, convenient installation electric wire are installed below described base plate.
As preferably, inside described U-bolt, it is provided with rubber blanket, keeps installation compact, prevent from causing when mounted structural damage.
The beneficial effects of the utility model are: the U-bolt of setting keeps cross-arm body construction compact, easy for installation, the L-shaped setting in cross-arm body cross section can strengthen structural strength effectively, when fixed plate keeps installing, stability is high, motion bar is hinged with cross-arm body and base plate respectively can keep the insulator on base plate to move when stress so that electric wire is difficult to be broken by external force.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model a kind of transmission tower cross-arm.
Detailed description of the invention
As shown in Figure 1, a kind of transmission tower cross-arm, including cross-arm body 1, U-bolt 2, motion bar 3 and base plate 4, the L-shaped setting in described cross-arm body 1 cross section, installing hole 5 and lower installing hole 6 it is provided with on described cross-arm body 1, it is additionally provided with fixed plate 7 on described cross-arm body 1, described U-bolt 2 is located in installing hole 5, it is provided with nut 8 on described U-bolt 2, described U-bolt 2 is connected by nut 8 is fixing with cross-arm body 1, described motion bar 3 is located at below cross-arm body 1, the described V-shaped setting of motion bar 3, described base plate 4 is located at below motion bar 3, described motion bar 3 is hinged with cross-arm body 1 and base plate 4 respectively.
Described fixed plate 7 is welded with cross-arm body 1.
Described fixed plate 7 undulate is arranged.
Below described base plate 4, insulator 9 is installed.
It is provided with rubber blanket 10 inside described U-bolt 2.
The beneficial effects of the utility model are: the U-bolt of setting keeps cross-arm body construction compact, easy for installation, the L-shaped setting in cross-arm body cross section can strengthen structural strength effectively, when fixed plate keeps installing, stability is high, motion bar is hinged with cross-arm body and base plate respectively can keep the insulator on base plate to move when stress so that electric wire is difficult to be broken by external force.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
