Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and in particular to an automatic unhooking mechanism for a transporting unmanned aerial vehicle and its application. Background Art

[0002] In high-altitude lifting, delivery and horizontal docking equipment, the hook is a key component connecting the crane and the heavy object, and is responsible for vertical transportation and hanging of heavy objects.

[0003] In the prior art, in order to prevent the rope suspended on the hook body from slipping, it is necessary to manually hold the rope when hanging it until the hook body is deflected by force, and when unhooking, the rope itself needs to slide out of the horizontal hook body. However, the hoisting rope has a certain toughness and is not easy to deform and bend, so it is easy to press against the inner wall of the hook body when there is no force, resulting in the phenomenon that it cannot fall off.

[0004] In order to automatically disengage the hook from the rope after the lifting is completed without the need for human intervention and unhooking, and to solve the problem of automatic unhooking during high-altitude delivery, we proposed an automatic unhooking mechanism and application for transport drones.

[0011] As a preferred solution of the automatic uncoupling mechanism for the transport drone described in the present invention, wherein: a sliding shaft is provided on the end of the third connecting rod away from the installation point; a sliding groove is provided on the second connecting rod, and the sliding groove tends to gradually approach the edge of the second connecting rod on one side close to the third connecting rod from top to bottom; the sliding shaft and the sliding groove are movably matched.

[0012] As a preferred solution of the automatic uncoupling mechanism for the carrier drone described in the present invention, a connecting column is provided at the end of the second connecting rod away from the positioning point, the sliding shaft and the connecting column are inclined and inclined in the same direction as the sliding groove; a first elastic member is provided between the connecting column and the sliding shaft.

[0026] Example 1

[0027] Reference Figure 1 , which is the first embodiment of the present invention, provides an automatic unhooking mechanism for a transport drone.

[0028] Specifically, the hanging assembly 100 includes a hook body 101; and

[0029] When the goods need to be hung, the hook body 101 is in a nearly horizontal state;

[0030] When the cargo needs to be unloaded, the hook body 101 rotates from a nearly horizontal state to a nearly vertical state.

[0031] The hook body 101 is used for lifting the cargo for transportation in cooperation with a lifting ring or a rope when the cargo is delivered from a high altitude.

[0032] By controlling the rotation of the hook body 101, when the hook body 101 is in a nearly horizontal state, it is convenient to hang the goods, and compared with the existing technology, it does not require too much human intervention; when the goods are transported to the designated location, the hook body 101 will become nearly vertical, and automatically unhook, avoiding the problem that the rope will be hung on the hook body 101 and cannot fall off. Through this setting, automation is improved and the manual operation process is greatly reduced.

[0033] Example 2

[0034] Reference Figure 1 to Figure 3 , which is the second embodiment of the present invention, is based on the previous embodiment, but differs in that an anti-slip concave surface 101a is provided on the hook body 101, and a first connecting rod 101b is further provided on the side wall of the hook body 101; a positioning point 101b-1 is provided on the first connecting rod 101b; the distance from the positioning point 101b-1 to the farthest edge of the hook body 101 is greater than the distance from the positioning point 101b-1 to the end of the first connecting rod 101b farthest from the hook body 101.

[0035] The anti-slip concave surface 101a has a certain depth, and when the ring or rope hanging on the goods is placed, it will slip; Figure 1 As shown, the positioning point 101b-1 is eccentrically arranged on the first connecting rod 101b.

[0036] When loading goods, the hook body 101 is close to a horizontal state, but not an absolutely horizontal state, and a certain deflection angle is allowed. Of course, in this setting, the hook body 101 is slightly tilted downward to facilitate scraping the lifting ring.

[0037] Preferably, the first connecting rod 101b is movably connected to the second connecting rod 102 via a positioning point 101b - 1 , and a connecting point 102a is provided between the center position of the second connecting rod 102 and the positioning point 101b - 1 .

[0038] Preferably, the second connecting rod 102 is movably connected to the frame 103 via a connection point 102a, a lifting ring 103a is provided on the frame 103, and a monitor 103b is also installed on the frame 103.

[0039] The second connecting rod 102 is movably connected to the frame 103 through the connecting point 102a, and the first connecting rod 101b is connected to the second connecting rod 102 through the positioning point 101b-1. In the normal state, that is, when the hook body 101 is close to the horizontal state, the second connecting rod 102 is set to be in a certain skewed state, not a completely vertical state.

[0040] The frame 103 is preferably symmetrically arranged outside the hook body 101 and integrally connected at the upper position; the frame 103 is preferably arranged in a triangular arch shape, and of course the frame 103 includes but is not limited to square, trapezoidal and other shapes.

[0041] The provision of the lifting ring 103a facilitates connection with some transport equipment.

[0042] The monitor 103b is mainly used to detect the status of the goods. When the goods arrive at the designated location or are placed, the cylinder 106 is started through the integrated control system, thereby automatically completing the unhooking action.

[0043] Preferably, a mounting point 101b - 2 is provided on one end of the first connecting rod 101b away from the hook body 101 , and the first connecting rod 101b is movably connected to the third connecting rod 104 via the mounting point 101b - 2 .

[0044] Preferably, a sliding shaft 104a is provided on the end of the third connecting rod 104 away from the installation point 101b-2; a sliding groove 102b is provided on the second connecting rod 102, and the sliding groove 102b tends to gradually approach the edge of the side of the second connecting rod 102 close to the third connecting rod 104 from top to bottom; the sliding shaft 104a and the sliding groove 102b are movably matched.

[0045] The third connecting rod 104 is arranged obliquely, and when the hook body 101 is in a nearly horizontal state, the angle formed by the third connecting rod 104 and the first connecting rod 101 b is an acute angle.

[0046] like Figure 2 As shown, the slide groove 102b is arranged inclined.

[0047] Preferably, a connecting column 102c is provided on the end of the second connecting rod 102 away from the positioning point 101b-1, and the sliding shaft 104a and the connecting column 102c are inclined and inclined in the same direction as the sliding groove 102b; a first elastic member 102c-1 is provided between the connecting column 102c and the sliding shaft 104a.

[0048] When the sliding shaft 104a moves in the sliding groove 102b, the sliding shaft 104a and the connecting column 102c are in an inclined state, and the inclined direction is consistent with the sliding groove 102b, and both are inclined in the same direction.

[0049] like Figure 3As shown, the diameters of the connecting column 102c and the end of the sliding shaft 104a are slightly larger to prevent the first elastic member 102c-1 from loosening and also to prevent the connecting column 102c from falling off from the sliding groove 102b.

[0050] The first elastic member 102c-1 is preferably a tension spring.

[0051] Preferably, a second elastic member 105 is provided between the third connecting rod 104 and the frame 103 .

[0052] Preferably, the second elastic member 105 is a spring.

[0053] Preferably, a cylinder 106 is also provided on the second connecting rod 102, and the cylinder 106 is located on one side of the end of the slide groove 102b, and the cylinder 106 maintains a parallel position with the inclination direction of the slide groove 102b; a limit plate 106a is provided at the output end of the cylinder 106, and the limit plate 106a is in contact with the outer wall of the sliding shaft 104a.

[0054] The cylinder 106 is located at one side of the bottom of the slide slot 102b, and is arranged so that the moving track of the output end of the cylinder 106 is parallel to the moving track of the slide shaft 104a; when the hook body 101 is in a nearly horizontal state, the slide shaft 102b is located at the bottom of the slide slot 102b, and the first elastic member 102c-1 and the second elastic member 105 are in a relaxed state. In order to prevent them from being compressed, the limit plate 106a on one side of the cylinder 106 presses against the slide shaft 104a from the upper outer wall to prevent it from moving; and when it is necessary to unhook, the monitoring plate 106a is pressed against the slide shaft 104a from the upper outer wall to prevent it from moving. After the detector 103b detects that the goods are placed, the cylinder 106 is started, the limit plate 106a will move, and the limit on the sliding shaft 104a will be cancelled. The first elastic member 102c-1 and the second elastic member 105 will be reset, so that the sliding shaft 104a moves to the other end of the sliding groove 102b. Correspondingly, the third connecting rod 104 will also move, thereby driving the first connecting rod 101b, so that the hook body 101 will rotate and make it close to the vertical state, so that the rope on the goods can be directly detached.

[0055] In summary, by setting the first connecting rod 101b and the second connecting rod 102 to be movably connected, when the cylinder 106 is started, the first connecting rod 101b will rotate around the second connecting rod 102, so that the hook body 101 is erected, which facilitates the automatic unhooking of the transported goods. In this process, manual intervention is greatly reduced.

[0056] Example 3

[0057] Reference Figure 1 to Figure 3, which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference is that after the cargo is transported to the designated position, the cylinder 106 is started to move the limit plate 106a, and the sliding shaft 104a moves from one end of the slide groove 102b to the other end, and the third connecting rod 104 drives the first connecting rod 101b to rotate, thereby realizing the cargo unhooking action.

[0058] By setting the cylinder 106 to start, when carrying goods, the limit plate 106a on the cylinder 106 presses against the sliding shaft 104a to ensure stable transportation of the goods. When the designated position is reached and the goods need to be unloaded, the restriction is released by starting the cylinder 106, so that the hook body 101 will flip over and automatically achieve the detachment of the goods.
