Technical Field
[0001] The utility model belongs to the technical field of wing hoisting tools, in particular to a wing disassembly and assembly hoist. Background Art
[0002] The wings of large UAVs are usually fixed and transferred using transfer racks or slings during disassembly and assembly. However, since tool boxes and parts racks are often placed on the ground at the disassembly and assembly site, it is not convenient to move and set up the transfer rack on the ground. Therefore, in many disassembly and assembly sites, a lifting device installed on the top of the frame is used to lift and transfer the wings through a sling. However, most existing slings are made of soft ropes, which make it difficult to maintain the balance and stability of the wings during lifting. Utility Model Content
[0003] In order to solve the deficiencies of the prior art, the utility model provides a wing disassembly and assembly lifting device, which can effectively ensure the balance and stability of the wing during the lifting process.
[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:
[0005] A wing disassembly and assembly lifting device comprises a connecting piece, the middle part of which is used for connecting the lifting equipment.
[0006] A directional slide is provided below one end of the connecting piece, and its length direction is perpendicular to the line connecting the two ends of the connecting piece; a movable slide is provided below the other end of the connecting piece, and a connecting shaft is provided above the middle part. The movable slide is swingably arranged around the axis, and the connecting shaft is movable along the direction of the line connecting the two ends of the connecting piece.
[0007] A pair of clamping claws are respectively slidably arranged on the directional slideway and the movable slideway, and hook plates are arranged at the lower ends of the two clamping claws on the opposite sides.
[0008] The beneficial effects of the utility model are as follows: the present solution utilizes the claws of a rigid structure to connect the wing, which can improve the stability of the connection to the wing; by moving the connecting shaft along the direction of the connecting line at both ends of the connecting piece, the force position of the wing can be adjusted more accurately to ensure the balance of the wing; and in order to adapt to the curvature of the wing, the movable slide can be rotated around the connecting shaft to adjust the clamping position between the claws set on the movable slide and the wing, thereby improving the connection stability of the sling to the wing, and being able to adapt to wings of different lengths and curvatures.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0016] like Figure 1 Figure 3 As shown, a wing disassembly and assembly lifting device includes: a connecting member 1, the middle part of which is used to connect the lifting equipment.
[0017] A directional slide 2 is provided below one end of the connecting member 1, and its length direction is perpendicular to the line connecting the two ends of the connecting member 1; a movable slide 3 is provided below the other end of the connecting member 1, and a connecting shaft 31 is provided above the middle part. The movable slide 3 is swingably arranged around the axis, and the connecting shaft 31 is movable along the direction of the line connecting the two ends of the connecting member 1.
[0018] A pair of claws 4 are slidably disposed on each of the directional slideway 2 and the movable slideway 3 , and hook plates 41 are disposed at the lower ends of the two claws 4 disposed in pairs on opposite sides.
[0019] Specifically, the connecting member 1 is a flat plate or a frame structure, the middle of which is connected to the cable of the lifting equipment through a set lifting ear or lifting hole; first, the claws 4 are moved to the two ends of the corresponding directional slide 2 or movable slide 3, so that there is enough size between the hook plates 41 to pass through the two sides of the wing; the lifting device is moved to the top of the wing by using the lifting equipment, and the connection direction of the two ends of the connecting member 1 is consistent with the length direction of the wing, and the directional slide 2 and the movable slide 3 are respectively facing the two ends of the wing. The directions of the directional slide 2 and the movable slide 3 can be reversed for use, which has stronger practicality; the claws 4 set in pairs on the directional slide 2 and the movable slide 3 are respectively passed through the two sides of the wing, so that the hook plate 41 is located below the wing ; Then move the paired claws 4 toward the middle, insert the hook plate 41 into the bottom of the wing, and use the hook plate 41 to support the bottom of the wing to fix the wing; in the process of connecting the sling to the wing, move the sling along the length direction of the wing to preliminarily adjust the force position of the wing, and move the connecting shaft 31 along the connecting line direction of the two ends of the connecting member 1 to more accurately adjust the force position of the wing, so as to ensure the balance of the wing; and in order to adapt to the curvature of the wing, the movable slide 3 can be rotated around the connecting shaft 31 to adjust the clamping position between the claws 4 set on the movable slide 3 and the wing, thereby improving the connection stability of the sling to the wing, and can adapt to wings of different lengths and curvatures.
[0020] Preferably, Figure 1 As shown, the connecting member 1 is a rectangular frame structure, which can ensure sufficient supporting strength while reducing the overall weight of the sling.
[0021] Preferably, Figure 1 As shown, a pressure plate 5 is provided below the middle of the connecting member 1, and the top of the pressure plate 5 is connected to the connecting member 1 via an elastic member 51. When the wing is hoisted, the pressure plate 5 is pressed against the top surface of the wing, and the wing is pressed against the hook plate 41 by this structure to prevent the wing from sliding.
[0022] Preferably, Figure 3 , Figure 4 As shown, the ends of the hook plates 41 are rotatably connected to support plates 42, which are inclined toward the top of the claws 4. An elastic plate 43 is provided between the bottom surface of the support plate 42 and the top surface of the hook plate 41. When the wing is hoisted, the support plate 42 contacts the bottom surface of the wing, and the elastic plate 43 is in a compressed state. By providing the support plate 42 and the elastic plate 43, the impact between the hoist and the wing can be reduced, thereby providing better protection for the wing.
[0023] Preferably, Figure 1 , Figure 3 and Figure 4As shown, the directional slide 2 and the movable slide 3 are both rectangular tube structures. The bottom surface of the rectangular tube is provided with a strip hole along the length direction. The upper end of the clamping claw 4 passes through the strip hole and is slidably arranged inside the rectangular tube. An adjusting screw 61 is arranged in parallel inside the rectangular tube, and its two ends have screws with opposite rotation directions. The screws at both ends of the adjusting screw 61 respectively pass through the upper ends of the paired clamping claws 4. By rotating the adjusting screw 61, the two paired clamping claws 4 can be controlled to move synchronously to the middle or both ends of the rectangular tube, so as to quickly connect or release the wing.
[0024] Further preferably, Figure 4 As shown, a driving motor 62 is provided in the middle of the rectangular tube, a worm 63 is coaxially provided on its main shaft, and a worm wheel 64 meshing with the worm 63 is coaxially provided on the adjusting screw 61. The driving motor 62 can drive the adjusting screw 61 to rotate, thereby achieving the purpose of automatically controlling the opening and closing of the claw 4.
[0025] Preferably, Figure 2 As shown, a pair of oppositely arranged slide grooves 11 are provided at one end of the connecting member 1 where the movable slide 3 is provided, with a gap between the pair of slide grooves 11, and the length direction of the slide grooves 11 is consistent with the direction of the line between the two ends of the connecting member 1, and a disc 32 is coaxially provided in the middle section of the connecting shaft 31, passing through the slide grooves 11 on both sides of the connecting shaft 31, and the edges of the disc 32 are slidably arranged in the slide grooves 11 on both sides, thus not only meeting the requirement of the connecting shaft 31 moving along the line direction between the two ends of the connecting member 1, but also meeting the requirement of the movable slide 3 rotating around the connecting shaft 31.
[0026] Further preferably, Figure 1 As shown, a pressure ring 33 is provided on the sliding sleeve of the connecting shaft 31, and a pressure spring 34 is provided between the upper part of the pressure ring 33 and the top of the connecting shaft 31. The pressure spring 34 is sleeved on the connecting shaft 31, and the pressure ring 33 is located above the entity of the slide groove 11. The pressure spring 34 is used to press the pressure ring 33 against the slide groove 11, which can fix the movement of the directional slide 2 in two directions, thereby improving the stability of the wing positioning.
[0027] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
