Detailed ways

The specific structure of the present invention will be described in detail below with reference to the accompanying drawings. the

Example

As shown in Figure 1-3, the power distribution cement pole live operating platform includes pinch head I 2 and pinch head II 3, pinch head I is connected with hydraulic motor 5 through screw 4, and hydraulic lifting rod 6 is connected to hydraulic motor. The head II is connected with the hydraulic lifting rod through a screw, the top of the hydraulic lifting rod is connected with the fixed frame 7, and the insulating plate 8 is fixed on the fixed frame; an insulating plate support 9 is arranged between the insulating plate and the fixed frame. the

The structure of the pinch head I and the pinch head II is the same, and the specific structure is that one end of the arc-shaped fixed plate I 201 and the arc-shaped fixed plate II 202 is respectively provided with a pulley I 203 and a pulley II 204, and the fixed plate I and the fixed plate The other end of II is fixed on the support plate 206 after being connected by movable shaft 205, and one end of support plate is provided with pulley 207; The circumference radius of described pulley I, pulley II and pulley is identical; There are hydraulic telescopic rods I 208 and hydraulic telescopic rods II 209 respectively on the sides, fixed holes I 210 and fixed holes II 211 are respectively arranged on the fixed plate I and the fixed plate II, and the fixed shaft I and the fixed shaft II respectively pass through the fixed holes I The fixed plate I and the fixed plate II are connected with the telescopic rod I and the telescopic rod II with the fixed hole II. the

The telescopic rod I and the telescopic rod II are connected with the leading screw. the

Before the operation, first install the climbing pole pinch head on the root of the concrete pole, and then pinch it on the concrete pole through the hydraulic system. The position of the working point is closer to the ground for the pinch head I. If you want to go up, the pinch head I will be stuck on the concrete rod through the hydraulic system, the pinch head II will be released, and the hydraulic lifting rod will be used to raise the pinch head II. It will rise to a certain position and stop rising. , the pinch head II is stuck on the concrete rod, at this time loosen the pinch head I, and use the hydraulic lifting lever to put up the pinch head I. When the pinch head I rises to a certain position, the concrete rod is blocked by the hydraulic system. Open the pinching head II, use the hydraulic lifting rod to raise the pinching head II, through the hydraulic system and the hydraulic lifting rod repeatedly, the operator of the insulating platform can be sent to the operating point. the

The concrete pole of the power distribution line uses the climbing pole to pinch the head and climbs up on the surface of the concrete pole. The concrete pole can be opened and closed through the hydraulic system, and the weight can be lifted by two people. When in use, according to the direction of the distribution line, The live working position selects the climbing direction of the machine, determines the size of the pinch head according to the diameter of the concrete rod, and uses the hydraulic lifting rod to move up and down with a stroke of 200 mm, and it is opened and closed for up and down. the
