The invention relates to the technical field of elevators, in particular to a worm and gear type elevator. The device comprises a bottom plate, two supporting foot frames are fixedly connected to the bottom of the bottom plate, a top plate is arranged above the bottom plate, a lifting mechanism is arranged between the top plate and the bottom plate and used for driving the top plate to vertically move up and down, wheel frames are symmetrically arranged on the upper surface of the top plate in a sliding mode, and dragging wheels are rotationally connected into the wheel frames. A distance adjusting mechanism is arranged on one sides of the two wheel carriers. According to the worm and gear type elevator, in the process that a top plate vertically moves upwards, dovetail joints on the two sides of a T-shaped rod slide towards the lower positions along the inner walls of two sliding grooves correspondingly, two external plates are pushed to synchronously move in the direction away from the T-shaped rod, then the distance between two wheel frames is increased, the supporting face of a workpiece on two dragging wheels is enlarged, and the workpiece is more stable. And the two dragging wheels can convey plate-shaped workpieces upwards more stably.
本发明涉及升降机技术领域,具体地说,涉及一种蜗轮蜗杆式升降机。其包括底板,所述底板底部固定连接有两个支脚架,所述底板上方设置有顶板,所述顶板和底板之间设置有升降机构,所述升降机构用于带动顶板竖直上下移动,所述顶板上表面对称滑动设置有轮架,所述轮架内部转动连接有拖轮,两个所述轮架的一侧设置有调距机构。该蜗轮蜗杆式升降机,在顶板竖直向上移动的过程中,通过将T型杆两侧的燕尾榫分别沿两个滑槽内壁向低处滑动,推动两个外置板同步向远离T型杆的方向移动,进而使两个轮架的间距增大,扩大工件在两个拖轮上的支撑面,使两个拖轮能够更为稳定地向上输送板状工件。
