Abstract
The utility model relates to a movable lifting ladder. Three sections of ladder racks which are in sleeve joint with each other are connected with a fixed plate with a circular arc-shaped angle on a bottom plate. One side of the first ladder rack is provided with a lifting gear driven coaxially with a winding drum. One end of a lifting steel cable is fixed with the winding drum, and the other end of the lifting steel cable in turn goes around the pulley of the first ladder rack, the pulley of the second ladder rack and the pulley of the third ladder rack, and is fixed on the lower end of the third ladder rack. The height and the angle of the movable lifting ladder can be adjustable, and the movable lifting ladder can be moved safely and reliably.
Description
The utility model relates to a kind of companion ladder.
A kind of companion ladder that is socket-connected and constituted by two joint ladders is arranged at present, and it is simple in structure, but poor stability is dangerous.
The purpose of this utility model provides a kind of good stability packaged type companion ladder.
The purpose of this utility model is achieved in that to be fixed with in the bottom side of base plate and is criss-cross stationary pipes, in an end inner chamber of every stationary pipes, all be socketed with the telescopic pipe that to do slip, and fixed by the holding screw on the stationary pipes, be provided with the castor lift adjustment bolt caster wheel that is hinged at an end of each root telescopic pipe, two circular arc fixed angle plates that are provided with angle adjustment holes are individually fixed in the upside of base plate, the three-section ladder frame of work chair is installed, a two-section ladder frame and a joint ladder socket-connect successively, on every joint ladder, be provided with pulley and crossbeam, the lower end, both sides of one joint ladder joins with connecting cylinder respectively, connecting cylinder joins with angle adjustment plate again, angle adjustment plate and circular arc fixed angle plate fix, side at a joint ladder is installed the lifter wheel that has handle, lifter wheel and reel crankshaft drive, installation sleeve is connected to the anti-fall self-lock pin of self-locking spring above lifter wheel, anti-fall self-lock pin can be meshed with lifter wheel, one end of lifting wire rope and the steel rope attachment point on the reel fix, the other end is walked around the pulley on the joint ladder successively, pulley on pulley on the two-section ladder frame and the three-section ladder frame, steel rope attachment point last and three-section ladder frame lower end fixes, and is provided with limited block down in the lower end of each ladder.
Because adopt such scheme, ladder height and angle can be adjusted arbitrarily, and be safe and reliable, good stability, conveniently moving.
Below in conjunction with drawings and Examples the utility model is done further narration.
