Description

Technical Field

The position of the second anti-skid roller 3 can be achieved through the distance adjusting device 9, so that it is close to or far away from the center of the anti-fall ring 1, thereby achieving the distance between the second anti-skid roller 3 and the other first anti-skid rollers 2, which is convenient for adapting to the thickness of the pole at different positions. Generally, the diameter of the pole decreases from bottom to top. By adjusting the position of the second anti-skid roller 3, it can be ensured that the plurality of first anti-skid rollers 2 and the second anti-skid wheels clamp the pole for protection. It should be noted that during the climbing process, the plurality of first anti-skid rollers 2 and the second anti-skid wheels roll on the pole, which will not affect the upward movement of the anti-fall ring 1.

[0039] like Figure 1-4 As shown, in this embodiment, as a preference, the anti-falling assembly 7 includes a first arc-shaped clamping plate 701 and a second arc-shaped clamping plate 702;

[0040] The first arc-shaped clamping plate 701 is arranged on the first handle bar 4 through the first connecting rod 703, and the first connecting rod 703 is arranged obliquely. The upper end of the first connecting rod 703 is connected obliquely upward to the first handle bar 4 and is located on the side of the first handle bar 4 close to the anti-fall ring 1, and the lower end of the first connecting rod 703 is connected obliquely downward to the outer side wall of the first arc-shaped clamping plate 701. The second arc-shaped clamping plate 702 is arranged on the second handle bar 5 through the second connecting rod 704, and the upper end of the second connecting rod 704 is connected obliquely upward to the second handle bar 5 and is located on the side of the second handle bar 5 close to the anti-fall ring 1, and the lower end of the second connecting rod 704 is connected obliquely downward to the outer side wall of the second arc-shaped clamping plate 702. The first arc-shaped clamping plate 701 and the second arc-shaped clamping plate 702 are arranged opposite to each other. When the anti-fall ring 1 is sleeved on the electric pole, the electric pole is located between the first arc-shaped clamping plate 701 and the second arc-shaped clamping plate 702.

When climbing the pole, grab the first handle bar 4 and the second handle bar 5 with both hands, and climb up with your feet buckled. At this time, both hands will apply downward pulling force to the first handle bar 4 and the second handle bar 5, so that the first arc-shaped clamping plate 701 and the second arc-shaped clamping plate 702 clamp the pole, so that the body can move upward, and the clamping and loosening operations are repeated. With the foot buckle, you can continue to climb upward. If the foot buckle slips or other things happen, your hands or the safety belt will apply a downward pulling force to the first handle bar 4 and the second handle bar 5, so that the first arc-shaped clamping plate 701 and the second arc-shaped clamping plate 702 clamp the pole to achieve the purpose of preventing falling. When working at high altitude, your hands are free, and the second anti-skid roller 3 is adjusted by the distance adjustment device 9, so that multiple first anti-skid rollers 2 and second anti-skid rollers 3 tightly clamp the pole. Since the two ends of the safety belt are respectively hung on the safety belt hanging rings 6 on the first handle bar 4 and the second handle bar 5, when the foot buckle suddenly slides down, the safety belt becomes straight and tightened, and a downward pulling force is generated on the first handle bar 4 and the second handle bar 5, so that the first arc-shaped clamping plate 701 and the second arc-shaped clamping plate 702 clamp the pole, and at the same time, multiple first anti-skid rollers 2 and second anti-skid rollers 3 also tightly clamp the pole, achieving double protection. The double insurance design can ensure that the staff is hung and avoid injuries caused by falling from a height.
