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

Embodiment Construction
[0024] Figure 1 to Figure 5 Among them, a gear 12 is set under the screw 7 of the lifting bracket rod of the self-locking joint rod lifting bracket, and a section of the lower end of the screw 7 is a non-threaded part 9, and the rest are threaded parts 8. The inner diameters of the screw 7 are respectively Each joint support pipe 1.2.3.4.5 and two bushings 6 are vertically covered with each other. And the outer ends of the leading screw 7 are respectively fitted together with the lifting joint rods 13.14. The upper end of 15.16 is processed with a circlip groove 28.29, and the circlip ring 26.27 can be buckled into the circlip groove 28.29. Except for the outermost lifting joint rod 13, the outer ends of the lower parts of the other lifting joint rods 14.15.16.17 are each processed for one section. Interlock groove 20, except the outermost two layers of lifting joint rods 13.14, the outer diameter surface of the lower end of each other lifting joint rods 15.16. There is a c...

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 inner screw of each lifting bracket rod to rotate through the gear, the corresponding screw in each lifting bracket rod drives its respective lifting joint rod to run vertically up and down one by one. It continues to rise after being connected with each section of the lifting section rods at the lower end by automatic locking, and as several lifting support rods rise synchronously section by section, the overall rise of the lifting support is promoted. Background technique [0002] The current elevator technology is mainly based on wire rope hoisting, so it is necessary to manually erect a huge lifting bracket, 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 s...
