Description

Technical Field

[0001] The utility model relates to the technical field of cross arm installation, in particular to a cross arm installation support labor-saving device. Background Art

[0002] Crossarms are mainly used to install electrical equipment on poles. As the line runs for a long time, the crossarms will gradually rust. Rusted crossarms need to be replaced to prevent damage to the electrical equipment installed on the crossarms. The traditional method of installing crossarms requires two workers to climb the pole. The workers pull the crossarms onto the poles through the transfer rope, adjust their standing positions and use safety belts to lift the crossarms to the designated position for assembly. In this installation method, workers generally use their arms and shoulders to support the crossarms, which increases the bearing capacity of the thighs, knees and waist, and is a great test of physical strength. At the same time, due to the consumption of physical strength, work efficiency is low, and there are certain safety hazards such as the crossarm falling due to lack of physical strength.

[0003] The invention patent with the publication number CN113756645A discloses a convenient tool for installing a crossarm, which includes a fastening assembly, an adjustment assembly and a bearing assembly. The adjustment assembly includes a support and a connecting rod, and the support is arranged on the side of the fastening assembly, and the support is connected to the fastening assembly through the connecting rod; the bearing assembly includes a bearing frame and a limiter, and the bearing frame is arranged at one end of the support away from the fastening assembly, and the limiter is arranged inside the bearing frame. The fastening assembly cooperates with the adjustment assembly to quickly hold the pole tightly, and use the horizontal detection observation instrument to check whether the crossarm is in a horizontal position, and use the adjustment assembly to level the crossarm, and install a fixed clamp to complete the operation. After the inspection is correct, the convenient installation tool can be removed, which frees up manpower to support the crossarm and greatly improves the work efficiency of the crossarm installation.

[0004] The above-mentioned convenient crossarm installation tool needs to operate the fastening components during installation and disassembly, and the process of operating the fastening components is relatively cumbersome and not simple enough, especially the convenient crossarm installation tool needs to be stably fixed on the pole, and there are many types of poles, and the tightening and adjustment of the above-mentioned fastening components is often inconvenient.
