Abstract
The invention relates to a worm and gear elevator which comprises a shell. A worm and gear mechanism is arranged in the shell, a worm gear is supported in the shell by a bearing, threads are arranged on an inner ring of the worm gear, a lead screw is penetratingly connected with the inner ring of the worm gear, external threads of the lead screw are matched with the internal threads of the worm gear, an anti-rotation pipe which is mounted on the shell sleeves the bottom of the lead screw, an anti-rotation check block is fixedly mounted at the bottom of the lead screw via screws, extends out of the anti-rotation pipe and is connected with a slide groove in the anti-rotation pipe, travel switches are respectively arranged at the upper end and the lower end of the slide groove, and the anti-rotation check block can be in contact with position switches which are the travel switches or can be separated from the position switches. The worm and gear elevator has the advantages that an anti-rotation slider at an end of the lead screw is used as the travel check block, so that the worm and gear elevator has an anti-rotation function and a travel control function, a component can be saved, and the structure can be simplified.
Description
Technical field
