The end of the cantilever sleeve 3121 near the walking leg 21 is hingedly connected to the base 311 and the end of the cantilever sleeve 3121 forms the hinged end of the cantilever 312. Specifically, a second rotating shaft hole is formed at the hinged end of the cantilever sleeve 3121, and the rotating shaft is inserted into the first rotating shaft hole and the second rotating shaft hole at the same time to realize the hinged connection of the cantilever sleeve 3121 and the base 311.
The cantilever sleeve 3121 is hollow inside, having a receiving space.
The resilient member 3123 is located within the receiving space of the cantilever sleeve 3121. One end of the elastic member 3123 near the base 311 is fixedly connected to the inner wall of the cantilever tube 3121, and the other end is used to connect to the telescopic arm 3122, that is, the two ends of the elastic member 3123 are respectively connected to the cantilever tube 3121 and the telescopic arm 3122.
One end of the telescopic arm 3122 is connected to the elastic member 3123, and the other end extends in a direction away from the cantilever sleeve 3121, and the end constitutes an extended end of the cantilever 312.
The telescoping arm 3122 is connected to a spring member 3123 so that the telescoping arm 3122 can telescope or retract relative to the cantilever sleeve 3121. That is, when the elastic member 3123 is stretched, the telescopic arm 3122 moves away from the cantilever sleeve 3121, and when the elastic member 3123 is compressed, the telescopic arm 3122 moves toward the cantilever sleeve 3121. The robot arm 313 is fixed at the extended end of the telescopic arm 3122 for gripping a cross beam or a longitudinal beam at the top of the habitat cage 4.
Referring to fig. 4 and 5, the robot 313 includes a main hook 3131, a latch hook 3132, a pressing bar 3133, and a switch 3134.
The main hook 3131 has a first end and a second end. The second end is fixedly connected with the extension end of the telescopic arm 3122. In this embodiment, the main hook 3131 is arc-shaped, and its central angle is greater than 180 degrees.
A concave second end of the main hook 3131 is provided with a groove 3136, an opening of the groove 3136 faces to a center of a circle of the main hook 3131. In this embodiment, the concave surface of the main hook 3131 constitutes the inner peripheral surface of the main hook 3131, and the convex surface constitutes the outer peripheral surface of the main hook 3131.
The groove 3136 includes a first receiving portion and a second receiving portion that communicate with each other. The first receiving portion extends in a radial direction of the main hook 3131, and has an opening toward the center of the circle, which constitutes an opening of the groove 3136. The second receiving portion extends in a circumferential direction of the main hook 3131, and is close to an inner circumference of the main hook 3131 with a space therebetween in a radial direction.
The caliber of the end part of the second accommodating part close to the first accommodating part is smaller than that of the end part far away from the first accommodating part.
Specifically, in the present embodiment, the second housing part is inclined in a direction away from the first housing part toward the concave surface of the main hook 3131, that is, in reference to the view direction of fig. 4, when the main hook 3131 is in a horizontal state, the second housing part is inclined downward in a direction away from the first housing part.
The hinged end of the locking hook 3132 is hinged to the first end of the main hook 3131, the free end of the locking hook 3132 fits into the first accommodating portion of the groove 3136, so that the free end of the locking hook 3132 can be clamped into the first accommodating portion, the locking hook 3132 and the main hook 3131 are closed, and the cultivation cage 4 can be grasped. When latch hook 3132 is closed with main hook 3131, the concave surface of latch hook 3132 faces main hook 3131, and the concave surface of main hook 3131 faces latch hook 3132.
A concave surface of the free end of the locking hook 3132 is provided with a locking groove 3137, and an opening of the locking groove 3137 faces to a center of a circle where the locking hook 3132 is located.
The shape of the card slot 3137 may be set according to practice. Strut 3133 has a hinged end and a free end. In this embodiment, the pressing rod 3133 is arc-shaped, and its convex surface faces the concave surface of the locking hook 3132. In other embodiments, the strut 3133 may be linear.
The hinged end of the pressing rod 3133 is fixedly connected with the hinged end of the locking hook 3132, and is hinged with the first end of the main hook 3131. A free end of the pressing lever 3133 has a space from a free end of the locking hook 3132. Specifically, the hinged end of the pressing rod 3133 and the hinged end of the locking hook 3132 are both fixedly connected to a rotating shaft, and the rotating shaft is hinged to the hinged end of the main hook 3131.
The pressing rod 3133 and the locking hook 3132 are sequentially arranged along the axial direction of the rotating shaft, that is, the plane where the pressing rod 3133 is located and the plane where the locking hook 3132 is located are sequentially arranged along the axial direction of the rotating shaft, so that, when the locking hook 3132 can be clamped in the groove 3136 by rotating, the pressing rod 3133 and the main hook 3131 have a gap in the axial direction of the rotating shaft and cannot be clamped in the groove 3136.
Therefore, rotation of either one of the pressing rod 3133 and the locking hook 3132 can drive the other one to rotate, that is, when the pressing rod 3133 is forced to rotate, the locking hook 3132 also rotates; when the latch hook 3132 is forced to rotate, the pressing rod 3133 also rotates.
When the pressing lever 3133 and the locking hook 3132 are not subjected to an external force and hang down only due to gravity, the pressing lever 3133 is located between the locking hook 3132 and the main hook 3131, that is, the pressing lever 3133 is closer to the recess 3136 in a circumferential direction of the main hook 3131. Referring to the view direction of fig. 4, the pressing bar 3133 is located at the right side of the locking hook 3132, and the groove 3136 is located at the right side of the pressing bar 3133. When the pressing rod 3133 is rotated upward by an external force, the locking hook 3132 is rotated upward until the locking hook 3132 is locked in the groove 3136.
In this embodiment, an included angle between the pressing rod 3133 and the locking hook 3132 is smaller than 90 degrees. In other embodiments, the included angle between the pressing rod 3133 and the locking hook 3132 may also be set according to the actual situation.
A switch 3134 is disposed at the groove 3136 to lock or unlock the latch hook 3132 located in the groove 3136. Specifically, the switch 3134 includes a stopper portion and a passing portion. The passing portion is adjacent to the first accommodating portion and is movable in the first accommodating portion and the second accommodating portion. The limiting part is far away from the first accommodating part, and the limiting part is limited in the second accommodating part by the second accommodating part. Specifically, spacing portion and passing portion are the step form, and spacing portion outwards surpasss the passing portion, and makes the passing portion can get into first portion of holding through the second portion of holding, and spacing portion can only be located the second portion of holding.
The passing portion is fitted with the locking groove 3137 of the locking hook 3132, and the passing portion is clamped in the locking groove 3137, so that the locking hook 3132 is locked.
The switch 3134 is disposed in the second receiving portion in a tilted manner, so that the main hook 3131 is positioned in the second receiving portion even though it is horizontally disposed.
Further, the position-limiting portion of the switch 3134 is a step-shaped large end, so that the switch 3134 is further ensured to be located in the second accommodating portion due to the gravity of the switch 3134.
The operation principle of the robot arm 313 is as follows:
referring to fig. 4, when the manipulator 313 is in a horizontal state, the latch 3132 is suspended below the main hook 3131 by gravity, and the switch 3134 is located in the second receiving portion by gravity. When the manipulator 313 tilts with the rising of the extending end of the telescopic arm 3122, specifically referring to fig. 5, the switch 3134 moves to the first accommodating portion due to gravity, and at this time, when the latch hook 3132 is located in the first accommodating portion, the switch 3134 and the latch slot 3137 of the latch hook 3132 can be snapped to lock the latch hook 3132.
The pulling member 314 is used to pull the cantilever 312. Specifically, one end of the pulling element 314 is fixed above the base 311, and the other end is fixedly connected to the middle of the cantilever 312. In this embodiment, one end of the pulling member 314 is fixedly connected to the walking leg 21 and is located above the base 311. The other end of the pull 314 is connected to the end of the cantilever sleeve 3121 near the telescoping arm 3122.
The pulling member 314 has elasticity, and when it is under tension, the pulling member 314 pulls the cantilever 312 to prevent the cantilever 312 from rotating downward. In this embodiment, the cantilever 312 is horizontal when the pulling element 314 is under tension.
Illustratively, the pull 314 is a cord having elasticity.
Further, the pulling member 314 can also erect the cantilever 312 on the side of the walking leg 21 when the grasping mechanism 31 is not operating.
The anti-sway principle of the anti-sway device will be explained by taking the example that the lifting device 2 lifts the cultivation cage 4 below the sea surface as follows:
when the cage 4 is not lifted to the sea, the gripping mechanisms 31 are in the initial state, i.e. the suspension arms 312 extend horizontally.
The lifting device 2 is lifted slowly, and when the cultivation box 4 is lifted to exceed the deck and the cultivation box 4 contacts the manipulator 313, the cultivation box 4 first contacts the compression bar 3133. When the breeding cage 4 continues to ascend, the breeding cage 4 applies an upward acting force to the pressing rod 3133, so that the pressing rod 3133 rotates from bottom to top, the locking hook 3132 rotates along with the pressing rod, until the breeding cage 4 is in contact with the main hook 3131, and the locking hook 3132 rotates to be located in the groove 3136, so that the manipulator 313 automatically grasps the breeding cage 4. That is, the four corners of the cultivation cage 4 are connected with a grabbing mechanism 31, so that the cultivation cage 4 has two acting forces in opposite directions in the length direction and the width direction.
Meanwhile, as the manipulator 313 is raised, the switch 3134 moves to the first accommodating portion of the groove 3136 under the action of gravity and is clamped in the clamping groove 3137 at the end of the locking hook 3132, so that the main hook 3131 and the locking hook 3132 are locked together, the locking hook 3132 is prevented from being unhooked, and the use safety of the anti-sway device is ensured.
As the habitat cage 4 continues to be raised, the cantilever sleeve 3121 is rotated up around the base 311. Meanwhile, the telescopic arm 3122 connected with the manipulator 313 is outwards slid under the action force of the breeding cage 4, and gives a pulling force to the connecting piece to extend the connecting piece, and the connecting piece simultaneously gives a reaction force to the breeding cage 4, so that the manipulator 313 can tightly grasp and automatically centralize the breeding cage 4, and the breeding cage 4 is prevented from shaking in the horizontal direction during ascending, descending and translation.
After the lifting device 2 lifts the cultivation cage 4 to a preset height, the lifting operation is stopped, and the cultivation cage 4 is lifted.
When the lifting device 2 is to be brought below the habitat cage 4 to the deck and below the sea surface:
the breeding cage 4 descends, and the telescopic arm 3122 drives the manipulator 313 to retract along the inner cavity of the cantilever sleeve 3121. The four cantilevers 312 of the gripping devices 31 return to the initial horizontal position as the cage 4 descends. At this time, the switch 3134 moves to the second receiving portion of the groove 3136 under the action of gravity, the locking hook 3132 automatically disengages from the main hook 3131 under the action of its own gravity, and the locking between the locking hook 3132 and the main hook 3131 is released, so that the cage 4 and the manipulator 313 automatically fall off.
When all work is completed, the corresponding boom 312 may be vertically fixed to the leg of the vehicle by the pulling member 314.
According to the technical scheme, the invention has the advantages and positive effects that:
the anti-shaking device comprises at least four grabbing mechanisms, the culture cage is grabbed by the mechanical arms of the grabbing mechanisms and is grabbed together, and the shaking of the culture cage in the horizontal direction is limited, so that the stability of the culture cage in the lifting, lowering or translation process is ensured, the position accuracy of the culture cage in the lifting process to the deck of the net cage and the position accuracy of the culture cage in the lowering process to the culture space are improved, and the operation efficiency and the operation safety of the whole culture platform are improved.
