The invention discloses a spiral gear lifting platform which comprises a supporting seat, a gear set and a lifting platform body. The supporting seat is composed of two side plates and two gear clamping plates, the two gear clamping plates are vertically fixed between the two side plates in parallel, the space clamped by the two gear clamping plates is a gear box, and a gear shaft hole and a gear long hole are formed in the center of each gear clamping plate from bottom to top; the gear set is composed of a circular gear and a spiral gear, the circular gear is arranged in the gear shaft holes through a rotating shaft, the spiral gear is arranged in the gear long holes through a lifting shaft, the spiral gear is always pressed on the circular gear under the action of gravity, a descending rocker arm is arranged on the rotating shaft, and an ascending rocker arm is arranged on the lifting shaft; and the lifting platform body is composed of two lifting plates and a panel, the lifting plates and the gear clamping plates are equal in width, the lifting plates are arranged at the outer sides of the gear clamping plates, the bottom ends of the lifting plates are arranged on the lifting shaft through mounting holes, and the panel is fixed to the top ends of the lifting plates. By means of the spiral gear lifting platform, the height of the lifting platform body is fixed without a brake device, and the trouble of operating the brake device back and forth is avoided.
本发明是一种螺旋齿轮升降台,包括支撑座、齿轮组和升降台;支撑座由两个侧板和两个齿轮夹板组成,两个齿轮夹板平行竖直的固定在两个侧板的中间,两个齿轮夹板所夹的空间为齿轮箱,齿轮夹板的中央由下而上开有齿轮轴孔和齿轮长孔;齿轮组由圆形齿轮和螺旋齿轮组成,圆形齿轮通过转轴设于齿轮轴孔内,螺旋齿轮通过升降轴设于齿轮长孔内,螺旋齿轮在重力作用下始终压在圆形齿轮上,转轴上设有下降摇臂,升降轴上设有上升摇臂;升降台由两个升降板和一个面板组成,升降板和齿轮夹板等宽,其设于齿轮夹板的外侧,升降板的底端通过安装孔设于升降轴上,面板固定在升降板的顶端。本发明无需制动装置来固定升降台的高度,避免了来回操作制动装置的麻烦。
