DETAILED DESCRIPTION

[0015] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Embodiment 1

[0016] A vertical lifting device for a reel assembly spraying, comprising a lifting part 1 and a buckle part 2, such as Figure 1 As shown, when the buckle part 2 is assembled with the lifting part 1, the reel assembly 3 can be lifted. A lifting hole 4 connected to a lifting device is formed at the center of the lifting part 1. A lifting device such as a crane can be used to pass the hook through the lifting hole 4 for lifting operations.

[0017] A plurality of laterally extending suspension arm structures 5 are provided around the lifting part 1, and the suspension arm structures 5 are evenly distributed around the circumference. Figure 2 As shown, the lifting part 1 includes a first beam plate 10 and a second beam plate 11. The first beam plate 10 and the second beam plate 11 are staggered and fixedly arranged in a cross shape. The two beam plates are cross-welded to form four suspension arm structures 5, and the two beam plates are arranged in a vertical plate shape. The plate surface of the beam plate is placed vertically to improve the longitudinal bearing capacity of the lifting part 1 and effectively improve the strength. Figure 2As shown, the first beam plate 10 and the second beam plate 11 form four laterally extending suspension arm structures 5. The surrounding suspension arm structures 5 are formed into a vertical plate shape. In order to avoid the beam plate from twisting and bending under gravity during the hoisting process, the two suspension arm structures 5 are reinforced and fixed. Specifically, a right-angle rib plate 12 is provided at the root where the first beam plate 10 and the second beam plate 11 intersect. Figure 2 As shown, the distal ends of two adjacent suspension arm structures 5 are reinforced and fixed by a support rod 13; the middle of the first beam plate 10 is convex upward to form a triangular plate, and a through waist-shaped hanging hole 4 is provided at the convex part of the middle of the first beam plate 10. In this way, the four suspension arm structures 5 are welded and fixed by a right-angle rib plate 12 at the center position, and the support rod 13 is provided at the distal end, so that the two adjacent suspension arm structures 5 can form a stable triangular structure, avoid the suspension arm structure 5 from deviating in the horizontal direction, and improve the overall firmness.

[0018] Furthermore, the suspension arm structure 5 is provided with a suspension point 6 that matches the buckle part 2; specifically, the upper edges of the ends of the first beam plate 10 and the second beam plate 11 are both provided with a groove-shaped suspension point 6, such as Figure 2 As shown, a groove-shaped suspension point 6 is formed at the end of the suspension arm, and at least one suspension point 6 is radially arranged at the end of the suspension arm structure 5. In this embodiment, only one suspension point 6 is exemplarily formed at the end of the suspension arm, and multiple suspension points 6 can be arranged in an array for the buckle part 2 to be suspended, so that it can be suitable for fixing workpiece flange plates 9 of different diameters.

[0019] Furthermore, the buckle portion 2 includes a claw portion 7 and a hook portion 8. Figure 3As shown, the clamping claw portion 7 is buckled on the edge of the workpiece flange plate 9, and a hook portion 8 is arranged on the upper side of the clamping claw portion 7. Specifically, the clamping claw of the buckling portion 2 is in an inverted F shape, and the clamping claw includes a vertical plate 14, an upper clamping rod 15, and a lower clamping rod 16. An upper clamping rod 15 and a lower clamping rod 16 are vertically fixed on one side of the vertical plate 14, and the workpiece flange plate 9 is clamped by the upper clamping rod 15 and the lower clamping rod 16. It can be understood that the spacing between the upper clamping rod 15 and the lower clamping rod 16 is processed in advance according to the workpiece of the reel assembly 3 to be processed, so that the spacing between the upper clamping rod 15 and the lower clamping rod 16 matches the thickness of the workpiece flange plate 9, and the upper clamping rod 15 can also be designed as a movable adjustable structure, so that it can be adjusted accordingly for workpiece flange plates 9 of different thicknesses, so that the lateral opening formed by the upper clamping rod 15 and the lower clamping rod 16 can be easily inserted into the workpiece flange plate 9, and A certain small gap is maintained with the surface of the workpiece flange plate 9 to avoid the workpiece flange plate 9 from forming a large relative movement with respect to the claw part 7; it can be formed to be easy to take and place and can be clamped on the workpiece flange plate 9 for lifting; further, the upper end of the vertical plate 14 is connected with a hook part 8, and the hook part 8 has a U-shaped opening 17 with an opening facing downward. After the claw part 7 is clamped on the edge of the workpiece flange plate 9, the lifting part 1 is dropped close to the workpiece flange plate 9, and each hook part 8 is correspondingly hung at the hanging point 6; the plane where the hook part 8 is located is perpendicular to the plane where the claw is located; so that when the U-shaped opening 17 is hung on the hanging point 6, the vertical plate 14 is attached to the side wall of the beam plate, and the mutual attachment between the two can provide a certain lateral stability to avoid shaking during the lifting process, and under the action of the gravity of the workpiece, the buckle part 2 can be firmly buckled with the lifting part 1 and will not fall. When in use, each hook part 8 is hung on the hanging point 6, and multiple claw parts 7 are distributed around the edge of the workpiece flange to form a connection point of the balanced lifting drum assembly 3.

[0020] Specifically, the lifting part 1 has two cross-shaped beams, the ends of the two beams form four groove-shaped hanging points 6, and the intersection of the cross beams forms a hanging hole 4 connected to the hook; the lower part of the buckle part 2 has a sideways protruding claw that is engaged with the reel, and the upper part of the buckle part 2 has a U-shaped hook with an opening facing downward, and the four buckle parts 2 are hung on the hanging point 6 through the U-shaped hook; when working, first install the buckle part 2 and the workpiece, and clamp the claw of the device buckle part 2 on the workpiece flange plate 9. In the next step, all four buckle parts 2 are correspondingly installed in the workpiece flange plate 9, and the mutual spacing is manually adjusted to ensure that they are roughly evenly divided, and then the buckle parts 2 are installed. In the next step, the lifting device hooks the lifting hole 4 with the crane hook, and the hook groove hanging point 6 of the lifting device is buckled with the U-shaped hook of the buckle part 2. The crane directly rises to complete the vertical lifting of the reel assembly 3 and perform the spraying operation. The device is suitable for vertical lifting of mooring drum spraying in the shipbuilding industry, with strong versatility, safety and reliability, and low production cost. The tooling can make the surface of the drum assembly 3 exposed, which is convenient for painting and other operations, and solves the problem of inadequate shot peening and painting on the surface of the drum assembly 3. Embodiment 2

[0021] In the aforementioned embodiment, under the action of gravity of the reel assembly 3, the buckle part 2 and the lifting part 1 can be fixed in a suspended form. However, on the one hand, it is not easy to control the center position of the reel assembly 3 to coincide with the center position of the lifting part 1 when the lifting part 1 and the buckle part 2 are installed and connected to each other, so that the center of gravity is easily deviated after hanging, causing certain risks to the lifting; secondly, since the upper center of the reel assembly 3 and the center of the lifting part 1 deviate from each other, the mutual engagement between the buckle part 2 and the suspension point 6 will also be affected, and it is often necessary to go through multiple adjustments before it can be hung in place, resulting in reduced efficiency; thirdly, in the process of lifting the reel assembly 3, only through the clamping of the claw part and the suspension of the hook part 8, during the lifting and transfer process of the reel assembly 3, it is easy for the claw part to be detached from the workpiece flange plate 9 due to collision and other reasons, causing danger.

[0022] As an improvement, Figure 4 As shown, it also includes a workpiece centering structure 18 for positioning the central tube of the reel workpiece. When in use, the blocking arm 21 in the workpiece centering structure 18 can be inserted and expanded from the upper end of the inner tube 24 of the reel assembly 3, so that the center of the reel assembly 3 and the lifting part 1 can overlap with each other.

[0023] Specifically, Figure 5 , 6As shown, the workpiece centering structure 18 includes a driving disk 19 and a centering slider 20. The centering slider 20 is slidably connected and arranged at the lower side of the suspension arm structure 5. The centering slider 20 extends downward and is provided with a blocking arm 21. Both sides of the suspension arm are provided with slide rails 25 for the centering slider 20 to move, so that the centering slider 20 can slide and change its position along the direction of the suspension arm structure 5 when sliding on the slide rails 25; the driving disk 19 is rotatably arranged on the lifting part 1, and a notch groove 26 for installing the driving disk 19 is provided at the intersection of the two beams. The driving disc 19 is coaxially arranged with the longitudinal axis of the lifting part 1, and a sleeve 27 is arranged in the central axis direction of the lifting part 1. A rotating shaft 28 is arranged in the center of the driving disc 19, so that the rotating shaft 28 is rotatably installed in the sleeve 27, so that the driving disc 19 can rotate freely. In actual use, a power mechanism (not shown in the figure) for controlling the rotation of the driving disc 19 can be added. The driving disc 19 can be controlled to rotate by a structure in which an electric motor and a reduction mechanism cooperate, or a combination of a worm gear can be used to manually control the rotation of the driving disc 19. Figure 5 As shown, the driving disc 19 is provided with a flat thread 22 on the side facing the centering slider 20. When the driving disc 19 rotates, the flat thread 22 rotates accordingly. The movement of each centering slider 20 around is controlled by the flat thread 22, so that the rotation of the driving disc 19 can simultaneously drive each centering slider 20 to slide along the suspension arm structure 5, so that the blocking arms 21 around can be simultaneously contracted or expanded, and then stuck on the inner cylinder 24 to realize the concentric positioning of the winding drum assembly 3 and the lifting part 1. Specifically, the centering slider 20 is provided with a rack 23 that forms a threaded match with the flat thread 22 on one side of the driving disc 19, as shown in FIG. Figure 6 As shown, the tooth profile of the rack 23 forms an arc shape, so that each tooth on the rack 23 can mesh with the plane thread 22; the rack 23 is installed on the upper end surface of the centering slider 20, so that the rack 23 and the plane thread 22 are threadedly matched. It can be understood that the four centering sliders 20 are matched with the same plane thread 22 at the same time, so when the driving disk 19 rotates, the four centering sliders 20 can be controlled to slide.

[0024] In actual use, each snap part 2 is first fixed to the workpiece flange plate 9 by the device claw part 7, and then the lifting part 1 is moved to the top of the reel assembly 3, the spacing of the blocking arms 21 is reduced in advance, and the lifting part 1 is controlled to move downward so that the blocking arms 21 are inserted into the inner cylinder 24 of the reel assembly 3, and then the expansion of each blocking arm 21 is controlled by the power mechanism. During the expansion process, the centering and fixing of the reel assembly 3 and the lifting part 1 can be achieved. It can be understood that it is not advisable to expand the blocking arms 21 and clamp them on the inner wall of the inner cylinder 24. A certain gap can be appropriately retained to allow the reel assembly 3 and the lifting part to be aligned with each other. The relative offset of the reel assembly 3 and the lifting part 1 can be controlled within a smaller range; after the centering of the reel assembly 3 and the lifting part 1 is completed, the snap part 2 can be rotated to the corresponding hanging point 6 when the lifting part 1 is rotated, and then the lifting part 1 can be lifted upward, that is, the snap part 2 can be snapped into the hanging point 6. In actual use, since the present embodiment increases the centering and positioning of the reel assembly 3, even if a collision occurs during movement, the relative movement of the reel assembly 3 is limited by the workpiece centering structure 18, so that the snap part 2 is not easy to fall off, thereby improving safety and improving the accuracy and efficiency of the workpiece installation process.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
