Balance cross arm described in the utility model, comprise cross-arm body, cross-arm body both sides are provided with symmetrical pull bar, pull bar is comprised of the first mounting panel connecting successively, the first screw rod, adjustable ring, the second screw rod, the second mounting panel, the first mounting panel is fixed on cross-arm body, the second mounting panel is fixed on shaft by anchor ear, and the first screw rod is connected with adjustable ring threaded one end, and the second screw rod is threaded with the adjustable ring other end; Cross-arm body middle part is fixed on shaft by U-shaped anchor ear, between cross-arm body and shaft, is provided with parallels, and parallels one end is fixed on the fixing hole place of cross-arm body, and the other end is fixed on cross-arm body arcuate socket place.
The first screw rod and the second screw rod are threaded with adjustable ring respectively, by rotating adjustable ring, can make the entire length of pull bar increase or shorten, thereby regulate the degree of balance of cross-arm body, when carrying out balancing, without unstick anchor ear with it, without cross-arm is sling, unclamp U-shaped anchor ear and parallels arcuate socket place bolt, after adjustment completes, locking again.Parallels arcuate socket can adapt to the angle adjustment in certain limit.
Described the first mounting panel and the first screw rod are welded and fixed, and the second mounting panel and the second screw rod are welded and fixed, and the second mounting panel is bolted on anchor ear.
Described anchor ear is positioned at cross-arm body below, and cross-arm body two ends are provided with porcelain vase.
Described anchor ear is positioned at cross-arm body top, and cross-arm body two ends are provided with link plate, by link plate, mount insulator.
Described cross-arm body along its length interval is furnished with handrail and pedal, handrail is distributed in cross-arm body upper surface, and pedal is symmetrically distributed in cross-arm body both sides, and operating personnel climb maintenance hand, can be by stepping down on pedal and advance with grasped handrail, climbing is convenient.
Described cross-arm body is comprised of girder and cant board, and its cross section is square, and cant board is welded on upper and lower girder both sides.
During use, cross-arm body is arranged on shaft by U-shaped anchor ear, by anchor ear, pull bar is fixed on shaft, when needs adjustment, by rotating respectively the adjustable ring of two lateral bracing struts, adjust its length, make cross-arm body balance, after having adjusted, by the bolted at U-shaped anchor ear and parallels place.
Compared with prior art, the beneficial effect the utlity model has is:
In the situation that this balance cross arm does not need to sling, cross-arm is carried out to balancing, regulate simply, greatly reduce intensity of workers, be convenient to the climbing of staff high-altitude, maintenance is convenient.
