Speed-limiting falling prevention inspection ladder
The invention discloses a speed-limiting falling prevention inspection ladder. The speed-limiting falling prevention inspection ladder comprises a first vertical ladder rod, a second vertical ladder rod and a plurality of pedal cross rods, wherein the first vertical ladder rod and the second vertical ladder rod are mutually parallel; the pedal cross rods are connected and arranged between the first vertical ladder rod and the second vertical ladder rod; a saw-toothed track chute is axially arranged on the front side of the first vertical ladder rod; a plurality of speed-limiting tensioning wheels are arranged in the saw-toothed track chute; a wire cable is connected to the axle of each speed-limiting tensioning wheel; and a buckle is connected to the tail end of each wire cable. By adopting the above structure, once a climbing person slips, the wire cables quickly slide down and pull the speed-limiting tensioning wheels, and owing to accelerated pulling of the wire cables, the speed-limiting tensioning wheels are triggered to automatically brake and get fixed in the saw-toothed track chute, so that the climbing person is prevented from continually slipping, and accordingly, the security of the climbing person is improved.
