Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
Example 1. The quick replacing device for the rudder suspension arm comprises a cross beam 1, wherein the bottom of the cross beam 1 is supported by a support frame 2, connecting joints 3 are distributed on the cross beam 1 along the length direction, and the number and the positions of the connecting joints 3 correspond to those of the suspension arm 5 on a stabilizer 4; the cross beam 1 can be leveled by stretching and retracting the support frame 2 in the vertical direction.
The support frame 2 comprises a tripod 21, a sliding sleeve 22 is arranged at the top end of the tripod 21, a lead screw 23 is connected in a sliding manner in the sliding sleeve 22, and a rod body of the lead screw 23 is in threaded connection with a hand wheel 24; the hand wheel 24 is arranged at the top of the sliding sleeve 22, and the sliding sleeve 22 limits the freedom degree in the vertical sliding direction; the top of the screw rod 23 is connected with the bottom of the beam 1 through a connecting seat 25.
