Embodiment Construction

[0024] Such as figure 1 As shown, the power transmission line disclosed in this embodiment descends the tower buffer seat along the anti-fall rail, and it includes a seat main body 1, face wheels 2, side wheels 3 and a drop buffer device 4.

[0025] Such as figure 1 , figure 2 As shown, the seat main body 1 includes a top plate 11 , a bottom plate 12 , and a side plate 13 . A pair of base plates 12 are connected under the top plate by side plates, and there is a gap between the two base plates, which is used for the web of the anti-falling track to pass through. The gap between the side panels is for the flanges of the fall arrest rail to pass through. The top plate 11 is an I-shaped plate; its abdomen is provided with a through groove, and the two sides of the through groove are provided with ear plates 14 to connect with the external anti-falling device; one end is provided with a mounting groove 15, and the mounting groove is a U-shaped opening. Groove, the outer end o...

Abstract

The invention discloses a tower buffer seat for a power transmission line along a fall prevention track, which includes a seat main body, a face wheel, a side wheel and a lowering buffer device; the seat main body includes a top plate, a bottom plate, and a side plate, and a pair of bottom plates are connected to the Under the top plate, one end of the top plate is provided with a mounting groove; the face wheel is connected to the outer end of the mounting groove, and the side wheel is assembled in the end of the side plate; the descending buffer device includes a friction pad, which is assembled at the inner end of the mounting groove, and the friction pad can relatively prevent The surface of the drop track moves to adjust the friction. When in use, it is stuck on the anti-fall track, and the friction pad is not in contact with the anti-fall track. Then it is carried to the tower by the external tower climbing robot. After the operation is completed, it needs to be controlled by the external tower climbing robot. The track is in contact, and the friction is adjusted by adjusting the contact tightness. Adjust the friction to offset its own gravity and the gravity of the tower climbing robot, and then give the seat body an initial downward velocity to descend at a constant speed without additional external power to descend the tower.

Description

technical field [0001] The invention belongs to the field of equipment for lifting and lowering towers on transmission lines, in particular to a buffer seat for lowering towers along transmission lines along anti-falling tracks. Background technique [0002] Transmission lines are mainly composed of conductors, insulators, towers, lightning conductors and grounding devices. Towers mainly play a supporting role. Transmission line towers are divided into iron towers and concrete towers according to materials. Iron towers account for more than 80% of transmission lines, especially 500kV and above lines currently account for 100%. [0003] In line operation and maintenance, electric shock and falling from high altitude are the two main factors that endanger personal safety. With the rapid development of power grid construction, the height of the iron tower is getting higher and higher, and the average height of the UHV line is more than 70 meters. When climbing the tower, it ta...
