A telescopic lifting device and its control method

Abstract

The invention relates to a telescopic lifting device comprising a base, a driving device, a telescopic rotation transmission device and a lifting column. The driving device is fixed to the base and comprises a driving motor and a controller which are in signal connection; the lifting column is connected with the driving motor through the telescopic rotation transmission device; the lower portion of the lifting column is fixedly connected to the base; and the upper portion of the lifting column is connected with the telescopic rotation transmission device. The telescopic lifting device has the beneficial effects that each segment of telescopic structure is provided with a thread screw-in pipe and a telescopic pipe; the telescopic pipes are controlled to rotate through the driving motor; then by means of the transmission between the telescopic pipes, the thread screw-in pipes are driven to stretch or shorten in the screw-in direction of threads; and by means of overall design, use is convenient, operation is convenient and fast, effects caused by the using environment are small in use, and the telescopic lifting device can be stretched long.

Description

technical field [0001] The invention belongs to the technical field of telescopic machinery, and in particular relates to a telescopic lifting device and a control method thereof. Background technique [0002] Straight-line long objects such as sticks, sticks, rods, piles, and columns are objects that people often encounter in daily life. In daily life, it is often necessary to adjust the length of straight-line long objects according to different needs. The length or height of a columnar object is a problem that people often face. Similarly, the strength and stretchability of a straight long object are also issues that people care about; When using it to play a supporting role, there is an urgent need for a flexible and easy-to-operate telescopic support device. [0003] In the application of general sticks, rods, rods, piles, and columns, it is necessary to determine the length or height of the sticks, rods, rods, piles, and columns to facilitate installation in the appli...

AI Technical Summary

Problems solved by technology

[0003] In the application of general sticks, rods, rods, piles, and columns, it is necessary to determine the length or height of the sticks, rods, rods, piles, and columns to facilitate installation in the applied structure. Once it is longer than expected, it will be broken Or the way of sawing off, and once it is shorter than expected, it will be lengthened and raised, which will cause inconvenience during use

In the prior art, tools such as jacks are usually used to support objects, but the use of jacks is inconvenient, and the use environment is easily restricted, which brings a lot of troubles to users
