And danger appears in order to prevent canoe from freely swinging on the folding and unfolding arm configuration, and the utility model also is provided with passive type and subtracts swinging mechanism, and details are as follows for its structure:
As shown in Figure 5, it is the structural representation that laterally subtracts swinging mechanism 75, it comprises one first damping oil cylinder 751, this first damping oil cylinder 751 has one first cylinder body 7511, this first cylinder body 7511 and one first adapter plate 7512 articulate, 7512 of this first adapter plates are fixed on the jib 21, make this first cylinder body 7511 to rotate relative to jib 21.Be provided with a first piston 7513 in this first cylinder body 7511, this first piston 7513 is divided into two hydraulic cavities with first cylinder body 7511, all is full of fluid in these two hydraulic cavities, and is interconnected by one first by pass valve 7514.A first piston bar 7515 stretches through in this first cylinder body 7511, and captive joint with this first piston 7513, all stretch out outside this first cylinder body 7511 at the two ends of this first piston bar 7515, and wherein an end is articulated on the teeter device 711 by first hinge 7516.Butt has one first damping spring 752 respectively between the corresponding end of two ends of first piston bar 7515 and first cylinder body 7511.
As shown in Figure 6, it is the structural representation that vertically subtracts swinging mechanism 72, it comprises one second damping oil cylinder 721, this second damping oil cylinder 721 has one second cylinder body 7211, this second cylinder body 7211 and one second adapter plate 7212 articulate, 7212 of this second adapter plates are fixed on the teeter device 711, make this second cylinder body 7211 to rotate relative to teeter device 711.Be provided with one second piston 7213 in this second cylinder body 7211, this second piston 7213 is divided into two hydraulic cavities with second cylinder body 7211, all is full of fluid in these two hydraulic cavities, and is interconnected by one second by pass valve 7214.One second piston rod 7215 stretches through in this second cylinder body 7211, and captive joint with this second piston 7213, all stretch out outside this second cylinder body 7211 at the two ends of this second piston rod 7215, and wherein an end is articulated on the longitudinal oscillation device 712 by second hinge 7216.Butt has one second damping spring 722 respectively between the corresponding end of two ends of second piston rod 7215 and second cylinder body 7211.
It is of the present utility model that to subtract the pendulum process as follows:
As shown in Figure 5, when teeter device 711 is done to rotate counterclockwise with respect to the 5th sections 215 of jib 21, the distance that first piston bar 7515 is articulated between the end on the teeter device 711 and first adapter plate 7512 shortens, distance between the other end of first piston bar 7515 and first adapter plate 7512 is elongated, the length of two first damping springs 752 is also corresponding to change, make that first damping spring 752 of left is compressed among the figure, and the first right-hand damping spring 752 is elongated among the figure, the direction of the restoring force of two the first damping springs 752 just in time sense of motion with teeter device 711 is opposite, can play a shock proof effect.Meanwhile, first piston bar 7515 drives first piston 7513 toward right-hand motion, make pressure balance no longer in two hydraulic cavities, in order to keep hydro-cushion, two interior fluid of hydraulic cavities must reflux by this first by pass valve 7514, because the shock damping action of first by pass valve 7514 has consumed the energy of teeter, the teeter amplitude that can decay plays the effect that subtracts pendulum.When teeter device 711 clockwise rotates with respect to jib 21, same reason, first damping spring 752 still has shock proof effect, and first damping oil cylinder 751 also can be reached the effect of decay teeter.
Again as shown in Figure 6, when longitudinal oscillation device 712 clockwise rotates with respect to teeter device 711, the distance that second piston rod 7215 is articulated between the end on the longitudinal oscillation device 712 and second adapter plate 7212 shortens, distance between the other end of first piston bar 7515 and second adapter plate 7212 is elongated, the length of two second damping springs 722 is also corresponding to change, make that second damping spring 722 of top is compressed among the figure, and second damping spring 722 of below is elongated among the figure, the direction of the restoring force of two the second damping springs 722 just in time sense of motion with teeter device 711 is opposite, can play a shock proof effect.Meanwhile, second piston rod 7215 drives second piston 7213 toward the top motion, make pressure balance no longer in two hydraulic cavities, in order to keep hydro-cushion, two interior fluid of hydraulic cavities must reflux by this second by pass valve 7214, because the shock damping action of second by pass valve 7214 has consumed the energy of longitudinal oscillation, the longitudinal oscillation amplitude that can decay plays the effect that subtracts pendulum.Certainly, when longitudinal oscillation device 712 rotates counterclockwise with respect to teeter device 711, same reason, second damping spring 722 still has shock proof effect, and second damping oil cylinder 721 also can be reached the effect of decay teeter, detailed process is similar, just will not give unnecessary details.
As shown in the above, the utility model by damping spring the shock resistance effect and the power consumption effect of damping oil cylinder, the swing of the boats and ships degree ground that has the greatest impact is reduced, with smoothly and finish safely the folding and unfolding safeguard work personnel of canoe and the safety of equipment.And, laterally subtracting swinging mechanism and vertically subtract swinging mechanism and be installed on orthogonal two planes, the oscillating motion that can decay and pass on arbitrarily angled has further improved and has subtracted the pendulum effect.
