Description

Transmission line iron tower cross arm

Technical Field

The utility model relates to the technical field of cross arm support, in particular to a cross arm of an iron tower of a power transmission line.

Background

The cross arm is an angle iron for transversely fixing the top of the telegraph pole, the porcelain insulator is arranged on the cross arm and used for supporting the overhead electric wire, the cross arm is an important component part in the pole tower, and the cross arm is used for installing insulators and hardware fittings to support the lead wires and the lightning conductor and keep a certain safety distance according to the regulations.

At present, most of cross arms for iron towers are fixed through a plurality of bolts, the bolts are easy to rust along with the time lapse or long-term wind and sun exposure, the phenomenon that the cross arms drop from high altitude is likely to be caused, and certain potential safety hazards exist.

Disclosure of Invention

The utility model aims to solve the defects in the prior art and provides a cross arm of a power transmission line iron tower.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a transmission line iron tower cross arm, includes the cross arm body, the top of cross arm body is provided with the support body, the catch has been cup jointed at the middle part of cross arm body, and this catch can laminate each other with the iron tower, the tip of catch is provided with the connecting rod, the one end of connecting rod runs through in the cross arm body, and the tip of connecting rod is provided with wears to insert the pole, the surface of wearing to insert the pole is equipped with the screw thread, the middle part of wearing to insert the pole is provided with the bolt, the bolt is threaded connection each other with wearing to insert the pole, and one side of bolt laminates each other with one side of cross arm body, the top of bolt is provided with protection machanism, protection machanism is located the lateral wall of support body.

As a preferable technical scheme of the utility model, the protection mechanism comprises an arc-shaped baffle cover, the baffle cover is positioned right above the bolt, a transverse plate is fixedly arranged in the baffle cover, and the transverse plate is made of stainless steel.

As a preferable technical scheme of the utility model, a baffle plate is fixedly arranged in the middle of the bottom end of the transverse plate, the size of the baffle plate is larger than that of the bolt, and overflow grooves are formed in two sides of the top of the baffle plate.

Compared with the prior art, the utility model has the beneficial effects that: the upper portion of catch and the junction of bolt is through setting up fender cover, baffle, and this fender cover is the arc shape, and the size of baffle is greater than the size of bolt, so can effectually block the rainwater when rainy day to accomplish the loss of rainwater through the overflow launder on the baffle, effectually reduced rainwater and bolt direct contact, thereby avoided the bolt to rust, improved later stage's security.
