Ball screw and sliding screw mutually nested type synchronous lifting photoelectric mast

Abstract

A ball screw and sliding screw mutually nested type synchronous lifting photoelectric mast belongs to the field of photoelectric mechanical devices for lifting, and comprises a main driving part set, a nesting type screw driving part set and an outer sleeve part set. The main driving part set comprises a hand operated driving part and the like, the nesting type screw driving part set comprises a single-joint sliding screw pair, a nested screw set, a planetary gear reducer component, a thrust bearing and a connecting part set of the thrust bearing, and the outer sleeve part set comprises an outer sleeve, a long guide key structure of the outer sleeve and a sleeve ring set with functions of guiding, fixed connecting and limiting. Sleeves in multiple sections are lifted simultaneously through screws in multiple sections and maintained at the speed unchanged. The mast stopping at any position can be integrally locked by a single sliding screw. By means of the synchronous lifting photoelectric mast, integral friction force is reduced, traditional unstable locking devices such as friction plates and the like are omitted, structure is simplified, smoothness and bearing capacity are improved, and high-precision photoelectric detecting equipment can be stably driven by lower driving force moment. The long guide structure is capable of providing a directional high-precision platform for the photoelectric equipment.

Description

Technical field [0001] The invention belongs to the field of photoelectric mechanical devices used for lifting, and particularly relates to a mechanically driven mast type equipment that adopts a ball screw pair and a sliding screw pair to nest and lock at the same time. Background technique [0002] The photoelectric equipment used in the detection, warning, tracking and other fields in the prior art is often limited by the terrain. It is a development trend to use such photoelectric equipment to be elevated. However, the photoelectric equipment has extremely high requirements for the accuracy of the load-bearing platform. The load capacity and self-locking stability of the load-bearing platform are also very demanding. Traditional mechanical lifting masts generally adopt a rope-type structure without internal driving components. The driving components are all multi-section lifting rod structures with sliding screws or the multi-section lifting rod structure where all driving co...

AI Technical Summary

Problems solved by technology

The rope-drawn structure has the disadvantages of large fit clearance, difficult self-locking, unstable base, etc.

The structure in which all the driving parts are ball screws has disadvantages such as poor self-locking stability, friction disc-like locking mechanism is easy to wear and age, etc.

The structure in which all the driving parts are sliding screws has disadvantages such as large frictional resistance and weak load capacity.
