A compact screw jack

Abstract

The invention provides a compact spiral elevator which comprises a connecting base. A supporting column is arranged at the center of the upper surface of the connecting base; a spiral track screws theouter side of the supporting column; the outer side diameter of the spiral track is 800mm; the spiral track is uniformly connected to the supporting column through a connecting rod; the upper and lower ends of the spiral track are connected to a driving wheel through a bearing; teeth are uniformly arranged on the outer side of the driving wheel; the space of the elevator can be reduced by means of the spiral track, so that the compact spiral elevator is more conveniently mounted; the connecting structure of a connecting chain is structured that a chain plate is connected to a chain plate through a pin roll without mounting a chain; the device directly drives the specially made chain plate by means of the driving wheel, so that the risk of oil contamination is structurally avoided. The compact spiral elevator is simple in structure and convenient to mount, and not only can the space of the elevator be effectively reduced, but also can avoid oil stain of the chains from polluting the environment effectively.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a compact spiral elevator. Background technique [0002] The elevator has become an indispensable tool in the production and life, and some places need to use the spiral elevator, but the existing spiral elevator uses a special plastic chain plate on the side bending chain, and drives the operation by driving the side bending chain. Therefore, due to the minimum turning radius of the side-bending chain and the style of the installed chain plate, the minimum outer diameter of the whole machine needs to be 1200mm. In addition, the oil on the chain does not meet the cleanliness requirements of special customers to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a compact screw elevator with simple structure and convenient installation, which can not only effectively r...
