Embodiment Construction

[0020] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0021] Such as Figure 1~4 As shown, the present invention mainly comprises upper support seat 7, lower support seat 8 and ratchet 30, and lower support seat 8 is provided with adjusting nut 11, and upper support seat 7 lower end is provided with adjusting screw rod 12, and adjusting screw rod 12 runs through lower support seat 8 And be screwed with adjusting nut 11. The end of the adjusting screw 12 is provided with a limit pin 13, and the limit pin 13 prevents the adjusting screw 12 from disengaging from the lower bracket seat 8. The relative distance between the upper bracket base 7 and the lower bracket base 8 is adjusted by adjusting the screw rod 12 and the adjustment nut 11 .

[0022] The front part of the upper end of the upper bracket seat 7 is connected to the first double-ended screw rod 21, the rear part of the upper end of the upper brac...

Abstract

The invention relates to an operation platform for replacing a flange screw of a steel tube tower, in particular to an operation platform for replacing the flange screw of the steel tube tower during the on-site overhauling of a power transmission line. The operation platform comprises an upper bracket holder, a lower bracket holder and a ratchet, wherein an adjusting nut is arranged in the lower bracket holder; an adjusting threaded rod is arranged at the lower end of the upper bracket holder, penetrates through the lower bracket holder, and is in threaded connection with the adjusting nut; the ratchet is arranged between a pressure plate and the upper bracket holder through bearings connected to the two ends of the ratchet; a stab plate is arranged on the middle part of the ratchet; a safety belt is connected to the stab plate; an upper beam penetrating through the upper bracket holder is arranged in the upper bracket holder; an upper jaw is connected to each of the two ends of the upper beam; a lower beam penetrating through the lower bracket holder is arranged in the lower bracket holder; and a lower jaw is connected to each of the two ends of the lower beam. The operation platform is lighter in self weight and convenient to adjust, is safely and reliably connected with a flange, and can be conveniently and quickly assembled and disassembled, the labor intensity of a worker is greatly reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an operation platform for replacing the flange screws of a steel pipe pole tower, in particular to an operation platform for replacing the flange screws of a steel pipe pole tower during on-site power transmission line maintenance. Background technique [0002] At present, when it is necessary to replace the flange screws of the steel pipe tower during the inspection and maintenance of the transmission line, two bamboo ladders are generally used to alternately bind the flanges on the flanges. Due to the heavy weight of the ladders, the operation is extremely inconvenient; Safety and reliability cannot be achieved, which greatly increases the labor intensity and operation risk of operators. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a safe, fast, time-saving and labor-saving working platform for replacing flange screws of steel pipe pole tow...
