Embodiment 1

[0027] Such as Figure 1 to Figure 5 As shown, the aerial work platform includes two clamping devices, the upper ends of the two clamping devices are connected and fixed by connecting rods 22, and the two ends of the connecting rods 22 are respectively fixed on the inverted U-shaped booms 2 of the clamping devices. The wire clamping device includes an inverted U-shaped boom 2, an upper pulley 3 powered by a motor 1, a lower pulley 4 and a fixed frame 6, the fixed frame 6 is narrow at the top and wide at the bottom, and the bottom of the fixed frame 6 of the two clamping devices A base 24 is connected between the ends, and a tool box and the like can be set on the base 24 . A guardrail 17 is arranged between the middle parts of the fixing frames 6 of the two clamping devices. One end of the guardrail 17 is hinged on the fixing frame 6 on one side, and the other end is detachably fixed on the other fixing frame 6 .

Abstract

The invention discloses an aerial operation platform for a single transmission conductor. The aerial operation platform comprises a conductor clamping device, wherein the conductor clamping device comprises an inverted U-shaped lazy arm (2), a fixing frame (6), a plurality of upper pulleys (3) and at least one lower pulley (4); one side of the fixing frame (6) is fixedly connected with one side ofthe inverted U-shaped lazy arm (2); the fixing frame (6) is fixedly connected with the plurality of upper pulleys (3) through a center shaft and a bearing; the center shaft is driven through a motor;the lower part of the fixing frame (6) is connected with a U-shaped support plate (8); the U-shaped support plate (8) is fixedly connected with one or more lower pulleys (4) through a center shaft IIand the bearing; and a first bolt (9) is arranged at the bottom of the U-shaped support plate (8). The aerial operation platform disclosed by the invention is simple in structure and convenient and safe to use, can be fixed on the conductor and can easily brake.

Description

technical field [0001] The invention belongs to the technical field of wire aerial work equipment, and in particular relates to an aerial work platform for a single power transmission wire. Background technique [0002] When the existing single wire aerial work platform used on the conductor of the transmission line works in environments with different pole heights such as some mountainous lines and individual plain lines, a section of rope is usually tied on the aerial work platform, and one end of the rope is located at On the pole tower, the sliding speed of the wire block is controlled by the manual pulling of the rope by the staff on the pole tower. This kind of control method is not easy to control the speed of the block, and the staff of the tower is time-consuming and laborious. When the height difference between the towers is large, the sliding speed of the block is difficult to control, which affects the personal safety of the operators and also brings hidden dange...
