Outdoor building outer-layer lifter rack

Abstract

The invention discloses an outdoor building outer-layer lifter rack. A rack slide rail is fixedly installed on the lateral surface of the rack, at least one retractable arm is embedded into the rack slide rail through folding rotary knobs, and each retractable arm includes an outer rod; a spring is installed in each outer rod, and an inner rod is sleeved with each outer rod; the folding rotary knobs are fixedly installed on the tops of the outer rods; straight wheels are fixed to the bottoms of the inner rods. The folding rotary knobs are in spherical structures, and after the folding rotary knobs are embedded into the rack slide rail, movable universal joints are formed. Notches are reserved at the upper end of the rack slide rail, and the retractable arms can be folded at the notches. Since the springs are installed in the retractable arms, collision to an outer wall of a building is effectively reduced, and meanwhile, the lifter rack can adapt to different outer wall structures. Thestraight wheels are fixed to the bottoms of the inner rods through rotating pieces, and the rotating pieces rotate at right angles; when the straight wheels move normally, the rotation direction of the straight wheels is vertical, more convenience is provided for movement, and the friction resistance is decreased; when the straight wheels do not move for work, the straight wheels rotate to the horizontal level through the rotating pieces to achieve an effect of stabilizing a rack body; by folding the retractable arms when the retractable arms are not in use, the storage space is saved.

Description

technical field [0001] The invention relates to the technical field of elevator electrical equipment, in particular to an elevator frame on the outer layer of an outdoor building. Background technique [0002] In the installation and maintenance of outdoor air conditioners in high-rise residential buildings, as well as in the work of floor wall painting, insulation layer treatment, glass cleaning, etc., it is necessary to apply outdoor building elevators. The traditional outdoor building elevators fix ropes from the top floor and hang them down. The rack is easy to collide with the floor wall or floor glass during use, causing unnecessary losses. For avoiding this problem, the general processing all is to be tied on the elevator frame with a rope downstairs and pull outwards to prevent collision, which is bothersome and unsafe. Contents of the invention [0003] The object of the present invention is to provide an elevator frame for an outer layer of an outdoor building, ...

Problems solved by technology

[0002] In the installation and maintenance of outdoor air conditioners in high-rise residential buildings, as well as in the work of floor wall painting, insulation layer treatment, glass cleaning, etc., it is necessary to apply outdoor building elevators. The traditional outdoor building elevators fix ropes from the top floor and hang down. The rack is easy to collide with the floor wall or floor glass during use, causing unnecessary losses

In order to avoid this problem, the general solution is to tie a rope to the elevator frame downstairs to pull it out to prevent collisions, which is both troublesome and unsafe.
