Description

Technical Field

[0001] The utility model relates to the technical field of hoisting machines, in particular to an electric cross-arm hoisting machine. Background Art

[0002] The power crossarm hoist is a device specially used for lifting power crossarms. The power crossarm is a supporting device installed on the line pole for fixing the insulating porcelain bottle. According to different power transmission requirements, the power crossarm has various specifications. The common ones are straight crossarms, whose size is L63*6*180, and the weight of a set of power crossarms is about 25kg. The size of the head crossarm is L75*8*180, and the weight of a set of crossarms is about 65kg. When installing the crossarm, the following two methods are generally used: when the installer climbs the pole, he carries the crossarm on his shoulder to the top of the pole and assembles it before installing it; when the installer climbs the pole first, he carries the crossarm on his shoulder to the top of the pole and assembles it before installing it. Climb to the top of the pole, use ropes to pull the crossarm to the top of the pole for assembly before installation. It is difficult for installers to use leverage when operating on the pole. Long-term installation work causes injuries to the waist, legs and other joints of the workers. After a certain age, due to decreased physical strength and other reasons, experienced installers are no longer competent for the job. This will bring a great burden to individuals and families, and companies also need to train new people. However, many young people are unwilling to accept this working model. Our national power grid system is actively developing and improving, and a large number of installers are needed. Traditional installation methods are difficult to attract new forces.

[0003] Existing lifting machines, such as the prior art with application number CN201920449786.3, include a base, a vertical pole, a support seat, a hinge hole, a capstan, a movable line, a rotating shaft, a reduction motor, a battery pack, a cross arm, a pulley and a threading port, etc. Since pulleys are installed at both ends of the cross arm, it is more labor-saving to retract and release the movable line, and the movable line is used to lift the electric cross arm through the hook pulley. The friction force of the movable line during lifting is small, and the entire lifting process is relatively labor-saving. It can effectively increase the weight range of the lifting electric cross arm, and is suitable for the installation and use of most electric cross arms.

[0004] However, the prior art can only be hoisted in the same position and direction, which reduces the practicality. In addition, the prior art is not convenient for fixing and clamping the power cross arm, which reduces the convenience. Utility Model Content
