Abstract

The invention provides an automatic pole climbing device and an electric maintenance vehicle, and relates to the technical field of electric power safety. The automatic pole climbing device comprises an operation platform, a first frame and a second frame, and the operation platform is fixed to the first frame; the first frame comprises a supporting assembly, an electric cylinder is arranged between the first frame and the supporting assembly, and the electric cylinder is used for pushing the supporting assembly to slide along linear guide rails; the automatic pole climbing device further comprises a linkage rod, one end of the linkage rod is hinged to the supporting assembly, the other end of the linkage rod is hinged to one end of a connecting rod, the middle portion of the connecting rod is fixed to the second frame through a rotating shaft, and the other end of the connecting rod is hinged to the end, far away from a driven friction wheel, of a U-shaped frame; and when the supporting assembly slides along the guide rails, the linkage rod enables the U-shaped frame to slide in the reverse direction. According to the automatic pole climbing device, a driving friction wheel and the driven friction wheel can simultaneously clamp an electric pole, uniform and symmetrical friction is provided, the pole climbing process is stable, operation is easy and convenient, and safety is high.

Description

technical field [0001] The invention relates to the technical field of electric power safety, in particular to an automatic pole climbing device and an electric power maintenance vehicle. Background technique [0002] The current climbing pole devices are roughly divided into two types: alternating type and roller type. Among them, the alternating type climbing pole device uses at least two parts that can clamp the electric pole, and achieves the purpose of lifting by clamping different pole heights of the electric pole in turn. , its advantage is that it is less affected by the diameter change of the pole when lifting, so it is suitable for various equal or non-equal diameter poles, but the disadvantage is that the speed is slow and the efficiency is low. The roller-type pole climbing device uses at least two sets of oppositely installed rollers to clamp the pole, and uses manpower or electricity to drive the rollers to rotate to achieve the purpose of lifting.

[0002] The current climbing pole devices are roughly divided into two types: alternating type and roller type. Among them, the alternating type climbing pole device uses at least two parts that can clamp the electric pole, and achieves the purpose of lifting by clamping different pole heights of the electric pole in turn. , its advantage is that it is less affected by the change of pole diameter when lifting, so it is suitable for various equal or non-equal diameter poles, but the disadvantage is slow speed and low efficiency

The roller-type pole climbing device uses at least two sets of oppositely installed rollers to clamp the pole, and uses manpower or electricity to drive the rollers to rotate to achieve the purpose of lifting. The advantages are fast speed and labor-saving, and the disadvantage is that it is greatly affected by the diameter change of the pole.

Since the pole is generally thicker at the bottom and thinner at the top, when the roller-type pole climbing device climbs to the upper part of the pole, the problem of slippage will occur due to the smaller diameter of the pole

[0003] In the prior art, the roller-type pole climbing device generally adopts the adjustment of the wheelbase between the driven wheel and the driving wheel to adapt to the influence caused by the diameter change of the pole during the lifting process, but the existing adjustment method is cumbersome to operate and poor in safety

[0004] For the operation and safety problems of the above-mentioned roller-type boarding device, no effective solution has been proposed yet.
