Self-locking rod lifting bracket

Abstract

The self-locking joint rod lifting support is an electric lifting support formed by combining a plurality of lifting support rods. When motors synchronously drive screw rods in lifting support rods torotate, the screw rods in each lifting support rod is meshed with nuts which are connected with the lower portion of each lifting joint rod one by one, and the nuts are enabled to drive the respective lifting joint rods to run on the respective screw rods; and when buckling tongue holes at the lower ends of the lifting joint rods of all the sections are lifted and unfolded in place, the top of the lifting joint rod arranged at the outer side end of the respective lifting joint rod hoops a buckling tongue in a sleeve, then the lifting joint rods are inserted into the buckling tongue holes in the lower ends of the lifting joint rods on the inner side layer under the elastic pressing effect of spring rings on the back of the lifting joint rods, the automatic interlocking is connected to theadjacent up-and-down two-section lifting joint rods, and then the lifting joint rods continuously connected with the outer side end; at the moment, a plurality of lifting support rods can synchronously ascend and descend in a node-by-section manner and can be combined to form a line-shaped, a parallel line-shaped, a delta-shaped, a #-shaped and other types of electric lifting supports.

Description

Technical field [0001] The invention relates to a self-locking joint rod lifting bracket, specifically: an electric lifting bracket composed of several lifting bracket rods. When the motor drives the lead screws of each lifting bracket rod to rotate through the gear, the lead screws in the corresponding lifting bracket rods drive their respective lifting joint rods to move up and down vertically. When each lifting joint rod is raised to its position, After being connected with the lower end of each section of the lifting joint rods automatically lock, continue to rise, as the several lifting bracket rods rise synchronously section by section, which promotes the overall rise of the lifting bracket. Background technique [0002] The current elevator technology is mainly based on wire rope hoisting, so it is necessary to manually set up a huge lifting bracket first, and the elevator can only rely on the lifting bracket to carry. Nowadays, the lifting brackets of all types of elevato...

AI Technical Summary

Problems solved by technology

[0002] The current elevator technology is mainly based on wire rope hoisting, so it is necessary to manually erect a huge lifting bracket first, and the elevator can only rely on the lifting bracket for transportation. Nowadays, the lifting brackets of various types of elevators are suitable for large loads and super heights. There is a certain degree of difficulty in erection, which highlights various shortcomings of the current lifting support technology

[0003] 1. After the wire rope hoisting structure is used for a long time, the wire rope is easy to elongate, become thinner or knotted, and there is often a danger of breaking the rope; and when the lifting is in place, it will gradually slide down, resulting in poor long-term positioning.

[0004] 2. Manually erecting the lifting support has low efficiency, high cost and poor safety

[0005] 3. The huge lifting bracket has poor adaptability to complex occasions, difficult processing, high manufacturing cost, and unfavorable intelligent control
