Synchronously lifted supporting leg

Abstract

The invention relates to a synchronously lifted supporting leg, which comprises first to [n]th arms sleeved in sequence from outside to inside, and n is not less than 3; the bottom of the first arm is connected with a bottom plate placed on the ground; each arm is inserted with a screw rod; the screw rod is sleeved with a nut; the nut is connected with the bottom of the second arm; the screw rod is connected with a driver for driving the screw rod to rotate; a plurality of chain wheels are mounted at the upper end of the [i]th arm, and i is not less than 2; each chain wheel is wound with a chain; and the two ends of the chain are connected with the bottoms of the [i-1]th arm and [i+1]th arm respectively. When the [i]th arm is moved up, the chain wheel at the upper end of the [i]th arm is moved up at the same time so that the [i+1]th arm is pulled by the chain to move up. The synchronously lifted supporting leg provided by the invention has the advantages that: the stability of a base station is improved by using high-intensity industrial section; the arms are synchronously moved, so that the lifting time is shortened; and the working state height of the base station is reduced in a multilevel lifting manner, thereby improving safety.

Description

technical field [0001] The invention relates to a synchronous lifting leg. Background technique [0002] At present, due to the high procurement cost of emergency communication vehicles and the cumbersome management and maintenance work, the number of use is limited, which cannot meet the emergency communication needs of sudden natural disasters, emergencies, and short-term large-scale gatherings that require rapid station establishment and rapid transition. All manufacturers are looking for an emergency communication mobile base station that can completely replace emergency communication vehicles; although many new products have been released, they have many shortcomings for the product legs: [0003] 1. After the outrigger rises to any height, the self-locking function is lacking, and it is easy to slide down and shift, and cannot work stably at any height during the lifting process; [0004] 2. Sequential lifting between each section of the arm, or use manual pins one by...

[0003] 1. After the outrigger rises to any height, the self-locking function is lacking, and it is easy to slide down and shift, and cannot work stably at any height during the lifting process;

[0004] 2. Sequential lifting between each section of the arm, or use manual pins one by one, the lifting speed is slow;

[0005] 3. The distance between the outriggers is small, and the wind resistance of the base station is weak;

[0006] 4. The outriggers cannot be hidden, which will a
