The invention relates to the technical field of elevators, in particular to a tightness-adjustable gear and rack elevator which comprises vertically and symmetrically arranged C-shaped steel, a lifting seat is vertically arranged on one side of the upper portion of the C-shaped steel, mounting frames are transversely arranged at the four corners of the side, close to the C-shaped steel, of the lifting seat, and rotating shafts are transversely and symmetrically inserted into the mounting frames; rollers and guide wheels coaxially sleeve the ends close to the rotating shafts, the rollers are inserted into the C-shaped steel, the peripheries of the guide wheels abut against the outer wall of the C-shaped steel, bearing seats symmetrically sleeve the peripheral surfaces of the rotating shafts, sliding seats are arranged at the bottoms of the bearing seats, and guide rails are symmetrically inserted into the bottoms of the sliding seats in a sliding mode. The guide rails are fixed to the two sides of the mounting frame respectively. Tightness can be adjusted, the distance can be adjusted in real time according to the abrasion condition, independent adjustment can be achieved according to the idler wheels with different abrasion degrees and gaps between the guide wheels, the replacement or maintenance frequency is reduced, and the maintenance cost is reduced.

    本发明涉及提升机技术领域,具体涉及一种松紧可调的齿轮齿条提升机,包括竖向对称设置的C型钢,所述C型钢上部一侧竖向设有提升座,所述提升座靠近C型钢一侧四角均横向设有安装架,所述安装架均横向对称插设有转轴,所述转轴靠近一端均分别同轴套设有滚轮以及导向轮,所述滚轮均插设于C型钢内部,所述导向轮外周均与C型钢外壁相抵,所述转轴外周面均对称套设有轴承座,所述轴承座底部均设有滑座,所述滑座底部均对称滑动插设有导轨,所述导轨均分别固定于安装架两侧。本发明可调节松紧,并且可以根据磨损情况实时调节间距,还能根据不同磨损程度的滚轮以及导向轮的间隙得到单独调节,减少更换或者维修次数,降低维保成本。
