Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to an airborne safety rope hanging rack lifting tool. Background Technique

[0002] The existing lifting tool for an airborne safety rope hanging rack is used to hang the hanging rack on the angle steel cross arm of an angle steel tower. The existing lifting tool includes a hook, a lifting rope and a hanging ring; among them, the hook can refer to the patent with the application number 2024104792662. The hook is installed on the upper side of the hanging rack. The lifting tool is a circular metal ring and is installed under the unmanned aerial vehicle through a lifting rope; when installing the hanging rack, the hook hooks the metal ring, and the unmanned aerial vehicle takes off. After hanging the hanging rack on the angle steel tower, the unmanned aerial vehicle moves downward, and the metal ring moves downward under the action of gravity and disengages from the hook, and then the unmanned aerial vehicle returns to the ground. Among them, the lifting rope of the existing lifting tool is generally made of materials such as nylon, and the texture is soft. After the unmanned aerial vehicle lifts the hanging rack, the lifting rope can twist freely, and the metal ring and the hanging rack are prone to rotate around the axis of the lifting rope in the air, and it often takes many times to successfully hang the hanging rack on the angle steel tower.

[0003] When it is necessary to remove the hanging rack from the angle steel tower, after the unmanned aerial vehicle flies above the hanging rack, it needs to move downward first to make the metal ring and the hook basically at the same height, and then the unmanned aerial vehicle moves horizontally, driving the metal ring to move horizontally towards the hook, so that the hook enters the metal ring. After the hook hooks the metal ring, the unmanned aerial vehicle lifts the hanging rack from the angle steel tower upward and brings the hanging rack to the ground. In actual operation, due to the high height of the hanging rack, it is difficult to observe clearly with the naked eye. After the metal ring of the lifting tool drops to the same height as the hook, it needs to move horizontally close to the hook to sleeved the hook. If the hook and the metal ring are not aligned, it needs to be tried many times, which increases the control difficulty of the unmanned aerial vehicle, and it is inconvenient for the metal ring to be connected to the hook in the air.

[0024] Next, through embodiments and in combination with the drawings, the technical solutions of the present invention will be further specifically described.

[0025] As Figures 1 to 6As shown in the figure, an airborne safety rope hanger includes: a chain 4, a collapsible sling ring 3, and a connecting mechanism 6; the sling ring 3 can be connected below the drone through the chain 4; the connecting mechanism 6 includes: a connecting column 61, a baffle 62, a stop post 63, a torsion spring, a hook plate 65, and two guide plates 64; the lower end of the connecting column 61 can be installed on the upper side of the hanger, and a downward-extending guide groove 611 is provided at the upper end of the connecting column 61; one end of the baffle 62 is hinged to one side of the guide groove 611, the stop post 63 is installed at the other end of the guide groove 611, the torsion spring is installed at the hinged end of the baffle 62, and the other end of the baffle 62 is pressed against the lower side of the stop post 63; the lower ends of the two guide plates 64 are respectively installed on the opposite sides of the upper end of the guide groove 611, and the upper ends of the two guide plates 64 are inclined outward; one end of the hook plate 65 is fixedly connected to the side of the connecting column 61, and the other end of the hook plate 65 is inclined downward for hooking the sling ring 3.

[0026] Through the above settings, first, the sling ring 3 is connected by the chain 4, and the sling ring 3 is not easy to rotate in the air, which is convenient for aligning with the hanger; second, after the sling ring 3 reaches above the connecting mechanism 6, the sling ring 3 can be connected to the connecting mechanism 6 by moving downward, improving the connection efficiency; third, the sling ring 3 is collapsible, which is convenient for storage, and the chain 4 is not easy to knot.

[0027] When the hanger of the present application is in use, on the ground, the upper end of the chain 4 is connected to the drone, the lower end of the chain 4 is connected to the sling ring 3, the connecting column 61 of the connecting mechanism 6 is vertically installed on the upper side of the hanger through fasteners, the hook plate 65 of the connecting mechanism 6 is manually hooked to the sling ring 3, and the drone lifts the hanger above the angle steel cross arm of the angle steel tower through the chain 4, the sling ring 3, and the connecting mechanism 6. The chain 4 can refer to the existing drive chain, which has a high tensile strength and can only bend in a plane and basically cannot twist, preventing the sling ring 3 and the hanger from rotating in the air, making it easier for the hanger to align with the angle steel cross arm. After the drone lowers the hanger, the hanger is placed on the angle steel cross arm. After the drone continues to move downward, the sling ring 3 and the connecting mechanism 6 are separated, and then the drone flies back to the ground.

[0028] The connecting mechanism 6 of the present application facilitates both the installation and disassembly of the hanging bracket. When disassembling the hanging bracket, the drone lifts the lifting ring 3 above the guide plate 64. After lowering the lifting ring 3, the lifting ring 3 slides into the guide groove 611 under the guiding action of the guide plate 64. And under the action of the gravity of the lifting ring 3, the baffle 62 is pushed to rotate downward. During the rotation of the baffle 62, the torsion spring twists. After the support rod 31 of the lifting ring 3 passes downward through the baffle 62, the torsion spring rebounds, and the baffle 62 rotates upward to contact the lower side of the stop post 63 again, completing the connection between the connecting mechanism 6 and the lifting ring 3. During the entire connection process, the drone only needs to fly downward once above the connecting mechanism 6 to connect the lifting ring 3 with the connecting mechanism 6, without horizontal movement, making the drone easier to control and the connection more efficient. After the lifting ring 3 is connected to the connecting mechanism 6, the drone flies upward. The drone lifts the lifting ring 3 through the chain 4. The stop post 63 prevents the baffle 62 from rotating upward. The support rod 31 of the lifting ring 3 lifts the hanging bracket upward through the baffle 62 and the connecting column 61. After the hanging bracket returns to the ground, the baffle 62 is manually rotated downward, and then the support rod 31 of the lifting ring 3 is removed from the guide groove 611.

[0029] As an implementation, the chain 4 includes a chain body 41 and a connecting member 42. The lower end of the chain body 41 is connected to the lifting ring 3, and the upper end of the chain body 41 is provided with the connecting member 42. A connecting hole 421 is provided on the connecting member 42; the hoisting device further includes a disengaging mechanism 5. The disengaging mechanism 5 includes a fixing member 51, a pin shaft 52, and a driving mechanism 53. The fixing member 51 and the driving mechanism 53 can both be installed on the lower side of the drone. A groove 511 is provided on the lower side of the fixing member 51. At least a part of the connecting member 42 is arranged in the groove 511. The pin shaft 52 passes through the connecting hole 421 of the connecting member 42. The driving mechanism 53 can be remotely controlled to drive the axial movement of the pin shaft 52.

[0030] Through the above settings, the drone is connected to the chain 4 through the disengaging mechanism 5; the drone can be separated from the chain 4 in the air, facilitating the drone to get out of trouble.

[0031] Furthermore, a sliding groove 512 is provided on the fixing member 51. The pin shaft 52 is slidably connected in the sliding groove 512. The driving mechanism 53 includes a servo motor 531, a rotating rod 532, and a pull rod 533. One end of the rotating rod 532 is installed on the output shaft of the servo motor 531. One end of the pull rod 533 is hinged to the rotating rod 532, and the other end of the pull rod 533 is hinged to the pin shaft 52.

[0032] Initially, as Figure 2 , the connecting member 42 is located in the groove 511. The pin shaft 52 horizontally passes through the connecting hole 421 of the connecting member 42. The left and right sides of the groove 511 are basically in contact with the connecting member 42, preventing the connecting member 42 from moving left and right in the groove 511, thereby preventing the connecting member 42 from disengaging from the pin shaft 52 and ensuring the connection between the drone and the chain 4; as Figure 3, one end of the pin shaft 52 protrudes from the surface of the fixing member 51 and is hinged to one end of the pull rod 533. The end of the pull rod 533 far from the pin shaft 52 is hinged to the lower end of the rotating rod 532, and the upper end of the rotating rod 532 is installed on the output shaft of the steering gear 531. When the lifting ring 3 is stuck on the angle steel tower, the UAV cannot return to the ground normally. When the ground operator remotely controls the steering gear 531 to drive the lower end of the rotating rod 532 to move away from the fixing member 51, the pin shaft 52 gradually opens the notch of the groove 511, the pin shaft 52 is pulled out of the connecting hole 421 of the connecting member 42, the connecting member 42 moves downward from the groove 511, and the separating mechanism 5 is separated from the chain 4, so that the UAV can return to the ground normally and prevent the UAV from crashing due to running out of power. Subsequently, the operator can climb the tower to remove the lifting ring 3 stuck on the angle steel tower. After the operator reinstalls the connecting member 42 into the groove 511, when the steering gear 531 drives the lower end of the rotating rod 532 to move towards the fixing member 51, the pin shaft 52 gradually closes the notch of the groove 511, the pin shaft 52 is inserted back into the connecting hole 421 of the connecting member 42, and the UAV is reconnected to the chain 4.

[0033] Further, the chain body 41 is set as a plastic drag chain. The chain 4 further includes a load-bearing rope 43. The load-bearing rope 43 is arranged inside the chain body 41 and extends along the axial direction of the chain body 41. One end of the load-bearing rope 43 is connected to the connecting member 42, and the other end of the load-bearing rope 43 is connected to the lower end of the chain body 41 to reduce the force on the chain body 41.

[0034] Through the above settings, it is convenient to reduce the weight of the lifting tool so as to reduce the load of the UAV.

[0035] In this application, the drag chain can be purchased on the market. The load-bearing rope 43 can pass through it inside. It has good anti-torsion performance. The material of the drag chain is plastic material, which is beneficial to reducing the weight of the lifting tool. The load-bearing rope 43 can specifically adopt a nylon rope, which has a high tensile strength. When the chain 4 lifts the hanging rack, the load-bearing rope 43 is tightened and basically bears all the weight of the hanging rack to prevent the drag chain from being damaged.

[0036] Further, the lifting ring 3 includes: a support rod 31 and two connecting rods 32; the support rod 31 can cooperate with the connecting mechanism 6 of the hanging rack; the lower ends of the two connecting rods 32 are respectively hinged to both ends of the support rod 31, the upper ends of the two connecting rods 32 abut against each other and are provided with through holes 321. A stud 7 is fixedly connected to the lower end of the chain body 41. The stud 7 passes through the through hole 321, and a nut 8 is threadedly connected to the stud 7 to lock the upper ends of the connecting rods 32 on the stud 7.

[0037] Through the above settings, the lifting ring 3 can be folded, which is convenient for storage.

[0038] Further, the middle part of the support rod 31 bulges downward to form a V-shaped structure.

[0039] With the above settings, after the lifting ring 3 lifts the connecting mechanism 6, the connecting mechanism 6 can automatically slide to the middle of the support rod 31, increasing the stability of the hanging rack in the air.

[0040] Furthermore, the connecting mechanism 6 further includes a prominent eyeball 66, and the prominent eyeball 66 is fixedly connected to the upper end of the guide plate 64.

[0041] With the above settings, it is convenient for the operator to visually observe the position of the upper end of the guide plate 64, so that when the lifting ring 3 moves downward, it can accurately slide into the guide groove 611 under the action of the guide plate 64.

[0042] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of this utility model.
