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
The present invention relates to a kind of synchronization lifting supporting leg.
Background technology
At present, because the Emergency communication vehicle purchase cost is expensive and management maintenance work is loaded down with trivial details, usage quantity is limited, can not satisfy precipitate disaster, accident, of short duration big assembly needs are built a station fast and cut to emergency communication demand such as build a station fast.A kind of emergency communication mobile base station that can replace Emergency communication vehicle is fully all being sought by each manufacturer; Many new products though come out of the stove, for the product supporting leg, they have numerous shortcomings:
1. supporting leg is after rising to arbitrary height, and the auto-lock function shortcoming easily takes place to lower slider and displacement, can not work by the arbitrary height position stability in lifting process;
2. order lifting between every joint arm, or adopt by the joint manual bolt, rising or falling speed is slow;
3. supporting leg erect-position spacing is little, a little less than the wind loading rating of base station;
4. supporting leg can not be hidden, and influences transition transportation and the outward appearance concordance of base station;
5. support leg functions is single, can only lifting, and terrain clearance height when descending fully, the base station resistance to overturning is poor.
6. cost height, complicated operating process;
7. maintenance is difficult, strongly professional;
8. regional environment for use narrow range, steadiness difference etc.
