Working principle: when the hoisting tool for rudder tests is used, as shown in fig. 1-10, firstly, according to the specification of rudder blades, two first screws 3 are rotated to adjust the distance between the first left sleeve plate 1 and the second left sleeve plate 4 and the distance between the first right sleeve plate 2 and the second right sleeve plate 5, at this time, two matched second screws 8 are far away from each other, the matched two second screws 8 still can rotate synchronously through a concave-convex matching structure, along with the position adjustment of the first left sleeve plate 1 and the second left sleeve plate 4 and the first right sleeve plate 2 and the second right sleeve plate 5, the transmission column 91 can be in the transmission sleeve 92, the transmission sleeve 92 can be driven to rotate by driving the guide post 93 to slide in the guide groove 94, and then the second screws 8 are driven to rotate in the adjusting groove 7, so that the movable block 101 and the adjusting seat 102 move towards the outer end and are influenced by the pitch of the second screws 8, the moving blocks 101 and the adjusting seats 102 at the outer ends move faster, so that the plurality of moving blocks 101 and the adjusting seats 102 can be distributed at equal intervals while the distance between the moving blocks is increased, further, along with the moving of the moving blocks 101 and the adjusting seats 102, the adjusting seats 102 can synchronously move inwards when moving in cooperation with the guiding of the adjusting blocks 103, because the width of the rudder blade which is longer in most cases is increased, and then the position of the adjusting seats 102 is synchronously changed at the moment, the distance between the two adjacent adjusting seats 102 is shortened, the upper auxiliary hanging strip 11 can still protect the wider rudder blade when the auxiliary hanging strip 11 is installed subsequently, the plurality of adjusting seats 102 can still keep the same horizontal position after moving through the adapting design of the lengths and the inclination angles of the plurality of adjusting blocks 103, the installation and the stable use of the upper auxiliary hanging strip 11 are facilitated, after the adjustment is completed, the first left sleeve plate 1 and the second left sleeve plate 4 are sleeved at the side edge position with wider rudder blade, the first right sleeve plate 2 and the second right sleeve plate 5 are sleeved at the side edge position with narrower rudder blade, then the upper auxiliary hanging strip 11 is fixed on the adjustment seat 102 through pins, and the first right sleeve plate 2 and the second right sleeve plate 5 are connected with the first left sleeve plate 1 and the second left sleeve plate 4;
Further, the movement of the adjusting seat 102 drives the mounting seat 12 to move through the rod piece, so as to drive the lower fixed auxiliary hanging strip 13 and the lower movable auxiliary hanging strip 15 to adjust positions, including transverse and longitudinal adjustment, and when the mounting seat 12 at the left side position transversely moves, as the toothed roller 14 is mounted in the mounting seat 12 in a damping manner, the friction force is large, at the moment, the toothed bar 184 can be driven to move towards the inner side through the gear 185, the inclined plane of the positioning rod 187 is stressed to stretch out and draw back in cooperation with the spring 186, the inclined plane enters different positioning grooves 188 to change positions, then a steel wire rope on a lifting tool such as a gantry crane is connected with the lifting lug 6, one end with a narrow rudder blade is lifted, in this process, the first left sleeve plate 1 and the second left sleeve plate 4 can be gradually folded over, so that the contact plate 182 contacts the ground and bears gravity, the contact plate 182 drives the movable strip 183 to move in the toothed bar 184, the toothed bar 14 is driven to rotate by meshing with the gear 185, the auxiliary toothed bar 14 and the lower movable auxiliary hanging strip 15 are meshed with the positioning rod 187, the rudder blade is not meshed with the lower movable blade 15, and the rudder blade is not contacted with the lower movable blade 15, and the rudder blade is further fixed to the position of the rudder blade is protected, and the rudder blade is not contacted with the lower than the fixed to the rudder blade 13 is protected by the lower blade, and the lower movable blade is covered by the movable blade 15;
When dismantling, manual pulling up locating lever 187, contact plate 182 drives movable strip 183 under the action of elasticity telescopic link 181 and resets this moment, and the follow-up continuous use of being convenient for avoids blockking down the dismantlement of movable auxiliary hanging strip 15 simultaneously, to the dismantlement of movable auxiliary hanging strip 15 down, can with first left sleeve plate 1, first right sleeve plate 2, left sleeve plate 4 of second and the right sleeve plate 5 of second split completely, take out from rudder blade tip again for lower movable auxiliary hanging strip 15 and lower fixed auxiliary hanging strip 13 dislocation split back reset again.
