[0034] First, move the device to the side of the climbing column, and make the left and right arc-shaped arms 3 on both sides of the climbing column, then start the electric screw 5 to rotate forward, the electric screw 5 rotates forward to drive the left and right arc-shaped arms 3 to move inward, the left and right arc-shaped arms 3 move inward and drive the left and right electric crawling wheels 4 to move inward, the left and right electric crawling wheels 4 move inward and contact the surface of the climbing column, the electric crawling wheels 4 are tightened on the climbing column, the staff then carry the tool into the manned frame 2, start the electric crawling wheel 4 to rotate, the electric crawling wheel 4 rotates to drive the arc-shaped arms 3 to move upward, the arc-shaped arms 3 move upward and drive the guide seat 1 to move upward, the guide seat 1 moves upward and drives the manned frame 2 to move upward, the manned frame 2 moves upward and drives the staff to move upward, the staff climbs along the height of the climbing column. The electric crawling wheel 4 stops driving the arc-shaped arm 3 to move upward, and the manned frame 2 also stops driving the staff to move upward, and the driving motor 10 is started to rotate forward to drive the bidirectional screw rod 9 to rotate forward, and the bidirectional screw rod 9 rotates forward to drive the left and right side movable plates 7 to move inward, and the left and right side movable plates 7 drive the left and right side arc-shaped clamping plates 8 to move inward, and the left and right side arc-shaped clamping plates 8 move inward and contact the surface of the climbing column, and the left and right side arc-shaped clamping plates 8 are clamped on the climbing column, and the arc-shaped clamping plates 8 fix the guide seat 1 on the climbing column through the movable plates 7 and the frame 6, and the arc-shaped clamping plates 8 further improve the stability of the device fixed on the climbing column, reduce the bearing capacity of the electric crawling wheel 4, and then turn off the electric crawling wheel 4. By closing the driving motor 10, the staff can start live working. When live working at different positions is required, the stepping motor 113 is started to rotate and drive the worm 114 to rotate. The rotation of the worm 114 drives the worm wheel 115 to rotate. The rotation of the worm wheel 115 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the first spur gear 111 and the second spur gear 122 to rotate. When the first spur gear 111 and the second spur gear 122 rotate forward, the first spur gear 111 rotates forward and drives the first movable rack 112 to move rightward. The first movable rack 112 moves rightward and drives the manned frame 2 to move rightward. The manned frame 2 drives the staff to move rightward. At the same time, the second spur gear 122 rotates forward and drives the second movable rack 121 to move leftward. The second movable rack 121 moves leftward and drives the staff to move rightward. The counterweight 12 moves to the left. Similarly, when the first spur gear 111 and the second spur gear 122 are reversed, the manned frame 2 drives the staff to move to the left and the counterweight 12 to move to the right. In this way, the counterweight 12 and the manned frame 2 move in opposite directions each time. When the manned frame 2 moves to the position where the operation is required, the stepper motor 113 is turned off, the counterweight 12 and the manned frame 2 stop moving, and the staff can continue the live operation. Due to the action of the counterweight 12, the force on the guide seat 1 can be balanced to prevent the manned frame 2 from being too heavy and causing one side of the guide seat 1 to be deformed by force, thereby ensuring the service life of the guide seat 1. When the live operation is completed, the stepper motor 113 is started to rotate, so that the counterweight 12 and the manned frame 2 move and reset, and the stepper motor 113 is turned off.The driving motor 10 is started to reverse and drive the bidirectional screw rod 9 to reverse. The bidirectional screw rod 9 reverses and drives the left and right movable plates 7 to move outward and reset. The movable plates 7 drive the left and right arc-shaped clamping plates 8 to move outward and reset. The arc-shaped clamping plates 8 reset and disengage from the climbing column. The arc-shaped clamping plates 8 stop clamping on the climbing column. Then the electric crawling wheel 4 is started to rotate in the opposite direction and drives the arc-shaped arm 3 to move downward and reset. The arc-shaped arm 3 drives the manned frame 2 to move downward and reset through the guide seat 1. The manned frame 2 drives the staff to move downward and reset. The staff gets off the manned frame 2, starts the electric screw rod 5 to reverse and drives the left and right arc-shaped arms 3 to move outward and reset. The arc-shaped arms 3 reset and drive the left and right electric crawling wheels 4 to move outward and reset. Then the device is transported to the designated position by the transport machine. In this way, through the action of the arc-shaped clamping plates 8, live operations can be performed more stably, reducing the load-bearing capacity of the electric crawling wheels 4, thereby improving the completeness of the operation of the operators.

The tail end of the pull wire 145 passes around the guide wheel 147 and is fixedly connected to the rear side of the bottom of the fixed plate 134.

[0037] When the device moves to the specified position, the buffer ball 132 contacts the ground, the buffer ball 132 is limited, the buffer ball 132 limits the movable rod 131, the manned frame 2 is lowered to drive the fixed seat 13 to move downward, the fixed seat 13 moves downward to compress the buffer spring 133, and then the electric crawling wheel 4 drives the arc arm 3 to move upward, the manned frame 2 drives the staff to move upward, the manned frame 2 moves upward to drive the fixed seat 13 to move upward, the fixed seat 13 first resets the buffer spring 133, and then the fixed seat 13 drives the movable rod 131 to move upward through the buffer spring 133, the movable rod 131 drives the buffer ball 132 to move upward, the buffer ball 132 moves upward and breaks contact with the ground, when the staff After the live working is completed, the manned frame 2 moves downward, driving the staff to move downward and reset. The manned frame 2 moves downward, driving the fixed seat 13 to move downward. The fixed seat 13 moves downward, driving the movable rod 131 to move downward through the buffer spring 133. The movable rod 131 drives the buffer ball 132 to move downward. The buffer ball 132 moves downward and contacts the ground. The buffer ball 132 stops moving downward. The buffer ball 132 causes the movable rod 131 to stop moving downward. The fixed seat 13 continues to move downward to compress the buffer spring 133. The buffer spring 133 can buffer the downward movement of the manned frame 2. In this way, the manned frame 2 can be prevented from moving downward and violently contacting the ground to cause damage, thereby ensuring the safety of the manned frame 2.

[0038] When the manned frame 2 is placed at the specified position, the manned frame 2 drives the rotating rod 141 to move downward through the mounting plate 14, and the rotating rod 141 moves downward to drive the baffle 142 to move downward. At the same time, the manned frame 2 also drives the wire wheel 147 to move downward through the fixing block 146. Since the buffer ball 132 is limited by contact with the ground, the movable rod 131 is limited, and the movable rod 131 limits the fixing plate 134. The fixing plate 134 limits the pull wire 145, and the wire wheel 147 moves downward to squeeze the pull wire 145, so that the pull wire 145 moves downward to drive the winding wheel 144 to rotate forward, and the forward rotation of the winding wheel 144 drives the rotating rod 141 to rotate forward, the winding spring 143 is compressed, and the rotating rod 141 rotates forward to drive the baffle 142 to swing downward 180 degrees and retract, and then the staff can enter the manned frame 2 for subsequent live operations, and when the manned frame 2 moves upward to drive the staff to move upward, the manned The frame 2 drives the baffle 142 to move upward through the mounting plate 14 and the rotating rod 141. At the same time, the manned frame 2 also drives the wire wheel 147 to move upward through the fixing block 146. The wire wheel 147 moves upward and stops to tighten the pull wire 145, and the pull wire 145 is relaxed. Due to the action of the coil spring 143, the rotating rod 141 reverses and drives the winding wheel 144 to reverse. The winding wheel 144 reverses and rewinds the pull wire 145 to reset. The rotating rod 141 reverses and drives the baffle 142 to swing upward 180 degrees to reset. The baffle 142 is reset to the rear side of the staff, and then when the staff performs live work, the baffle 142 can block and protect the rear of the staff. When the live work is completed, the manned frame 2 moves downward to reset, and the rotating rod 141 drives the baffle 142 to swing downward 180 degrees to reset again.

The arc-shaped clamping plates 8 on the left and right sides are clamped on the climbing column by the friction blocks 15, and the friction blocks 15 can increase the friction between the arc-shaped clamping plates 8 and the climbing column. When the arc-shaped clamping plates 8 on the left and right sides move outward to reset, the arc-shaped clamping plates 8 on the left and right sides drive the friction blocks 15 on the left and right sides to move outward to reset. In this way, the arc-shaped clamping plates 8 can be clamped on the climbing column more stably, thereby improving the clamping effect of the arc-shaped clamping plates 8.

[0042] When the worker enters the manned frame 2, the worker contacts the insulating pad 16, and the insulating pad 16 can prevent the current from contacting the worker, so as to prevent the worker from being electrocuted and causing dangerous accidents, thereby ensuring the safety of the worker's operation.
