Abstract
The utility model provides a worm wheel lead screw elevator which comprises a machine body. The inside of the machine body is provided with a worm wheel, a worm and a lead screw, wherein the bottom end of the lead screw is provided with slide blocks, the worm wheel is meshed with the worm, the worm wheel is connected with the machine body in a rotating mode through a bearing, the outside of the bearing is provided with a bearing cap, the lead screw and the worm wheel are connected through threads, a guide sleeve is arranged between the lead screw and the bearing cap, the lead screw outside the machine body is provided with a shell body, and the shell body is fixedly connected with the machine body, the shell body is provided with an elongated slot, the elongated slot portion on the shell body is provided with two supports, and the insides of the supports are respectively provided with an approach switch. The worm drives the worm wheel to rotate, the worm wheel drives the lead screw to move up and down through trapezoidal threads, the slide blocks at the lower end of the lead screw contact the approach switches to send signals for stopping, and therefore the worm wheel lead screw elevator has the advantages of being simple in structure, convenient to maintain, long in service life, stable in working, safe and reliable in performance and the like.
Description
Technical field
The utility model belongs to the lifter apparatus field, especially relates to a kind of Worm gear feed screw lift.
Background technique
In the manufacture process of steel pipe, need to use screw lift to exchange the nearly switch of corner connection and control, in existing technology, the complicated structure of screw lift, assembling difficulty is large, has the technical problems such as screw mandrel is fragile, job insecurity.
Summary of the invention
Problem to be solved in the utility model provides a kind of long working life, working stability, the reliable Worm gear feed screw lift of performance safety, is particluarly suitable for using in the angle modulation approach switch mounting mechanism of steel tube factory.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Worm gear feed screw lift, comprise body, be provided with worm gear in the described body, worm screw and screw mandrel, the bottom of described screw mandrel is provided with slide block, described worm gear and worm meshing, described worm gear is connected by bearing rotary with body, and described bearing is provided with bearing cap outward, and described screw mandrel and worm gear are threaded connection, be provided with guide sleeve between described screw mandrel and the bearing cap, described extra-organismal screw mandrel is provided with housing, and described housing is fixedly connected with body, and described housing is provided with an elongated slot, elongated slot place on the described housing is provided with two supports, respectively is provided with an approach switch in the described support.
Further, described slide block is convex.
Further, the screw thread that links to each other with described screw mandrel of described worm gear is trapezoidal thread.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, worm screw drives the worm gear rotation, and worm gear drives screw mandrel by trapezoidal thread and moves up and down, and the slide block touching approach switch of screw mandrel lower end sends the signal newspaper and stops; Have simple in structure, easy to maintenance, the advantage such as long working life, working stability, performance safety are reliable.
