Abstract

The invention provides a power transmission line tower climbing manned chair along an anti-falling track, and relates to the technical field of power transmission line tower climbing, the power transmission line tower climbing manned chair comprises a steel rail, a tower climbing device is arranged on the surface of the steel rail, a manned device is arranged on the surface of the steel rail, a tower climbing rope is arranged between the tower climbing device and the manned device, an anti-falling device is fixed on the bottom surface of the manned device, and the anti-falling device comprises supporting plates; an anti-falling block is arranged between the supporting plates, a triggering block is arranged on the surface of the anti-falling block, a limiting block is fixed between the supporting plates, a fixing block is fixed between the supporting plates, and reset springs are fixed between the anti-falling block and the triggering block and between the anti-falling block and the fixing block respectively; and when the manned device drives the anti-falling device to fall rapidly, the anti-falling block cannot reset within a short time, so that the anti-falling block is clamped with a blocking groove, the design can realize timely emergency braking when the device falls rapidly, the anti-falling performance of the device is improved, and the anti-falling device has a simple structure, the effect is obvious, and the cost is reduced has improved the security performance of device.

Description

technical field [0001] The invention relates to the technical field of power transmission line climbing towers, in particular to a power transmission line climbing tower manned chair along a fall prevention track. 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%. Among them, 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 takes a lot of physical strength and time to clim...
