Technical Field
[0001] The utility model relates to the technical field of transfer, in particular to a transfer sling. Background Art
[0002] As Figure 1 Shown in Summary of the Utility Model
[0003] The utility model provides a transfer sling to solve the deficiencies of the above-mentioned prior art, solve the problems of cumbersome transfer operation and potential safety hazards, and has strong practicability.
[0004] In order to achieve the purpose of the utility model, the following technology is proposed: s
[0005] A transfer sling includes a cross plate. A middle column is provided at the geometric center of the cross plate. A collar is provided on the middle column. The collar is hung on the hook of a traveling crane to facilitate the transfer operation of the shell.
[0006] A plurality of pull rods are provided on the cross plate. A middle plate is sleeved at the lower end of the pull rod. Support plates are circumferentially arranged on the outer periphery of the middle plate. A pair of guide holes are formed in the support plates. The length direction of the guide holes is parallel to the length direction of the support plates. Connecting screws are inserted into the guide holes. Upper moving plates are provided at the upper ends of each pair of connecting screws. Lower moving plates are provided at the lower ends of each pair of connecting screws. The lower moving plates are vertically arranged. The lower ends of the lower moving plates are bent inward to form hook plates. Rectangular holes are formed in the lower moving plates. A pair of convex parts are provided on the inner walls of the lower moving plates. Rotating pressing plates are rotatably provided on the convex parts. Waist-shaped holes are formed at the outer ends of the rotating pressing plates. A notch is formed at the outer end of the rotating pressing plate in an open manner. A through rod is inserted into the waist-shaped hole. An upper pulling plate is provided on the through rod. The upper pulling plate passes through the outer end of the support plate, and the upper end of the upper pulling plate is installed on the cross plate. The hook plate can move inward so that its lower end hooks on the lower wall of the upper flange. When lifting, the entire shell can be lifted. When the shell is lifted upward, the cross plate can pull the upper pulling plate to move upward first. When the upper pulling plate moves upward, it will act on the inner wall of the waist-shaped hole through the through rod, so that the inner end of the rotating pressing plate rotates downward, and then the inner end of the rotating pressing plate acts on the upper wall of the upper flange, thereby improving the safety during transfer.
[0007] Further, a limit nut is provided at the lower end of the pull rod to facilitate the control of the upward pulling distance.
[0008] Furthermore, a rotating head is installed at the inner end of the support plate. A rotating concave plate is rotatably provided at the upper end of the rotating head. An activity hole is provided on the rotating concave plate. A T-shaped plate is inserted through the activity hole. An inner top plate is provided at the inner end of the T-shaped plate. The inner top plate is located inside the rotating concave plate. A spring is provided at the outer end of the inner top plate. The outer end of the spring is provided on the outer end of the rotating concave plate. A vertical pulling plate is provided at the inner end of the upper moving plate. Through the provided rotating concave plate, the inner top plate provided therein can act on the vertical pulling plate, thereby preventing the hook plate from moving outwards, ensuring that the hooked section at the lower end of the hook plate can act on the lower wall of the upper flange, thus enhancing the safety during transfer. The setting of the spring enables the rotation of the rotating concave plate.
[0009] Furthermore, a holding rod is provided at the outer end of the rotating concave plate. The provided holding rod facilitates the rotation operation of the rotating concave plate.
[0010] Furthermore, a bayonet is provided on the outer wall of the vertical pulling plate. An inner clamping head is provided at the inner end of the inner top plate. The inner clamping head is inserted through the bayonet. The reliability of limiting the hook plate can be further enhanced through the inner clamping head.
[0011] The advantages of the above technical solution are as follows:
[0012] The utility model facilitates the lifting and transfer of the shell and also improves the safety during lifting and transfer. BRIEF DESCRIPTION OF THE DRAWINGS

Support plates 30 are arranged in a circumferential array on the outer circumference of the middle plate 3. A pair of guide holes 31 are formed in the support plate 30. The length direction of the guide hole 31 is parallel to the length direction of the support plate 30. Connecting screws 32 are inserted into the guide holes 31. Upper moving plates 33 are provided at the upper ends of each pair of connecting screws 32. Lower moving plates 34 are provided at the lower ends of each pair of connecting screws 32. The lower moving plate 34 is arranged vertically. A hook plate 6 is bent inward at the lower end of the lower moving plate 34. A rectangular hole 35 is formed in the lower moving plate 34. A pair of convex parts 36 are arranged on the inner wall of the lower moving plate 34. A rotating pressure plate 37 is rotatably arranged on the convex part 36. An oblong hole 38 is formed at the outer end of the rotating pressure plate 37. A notch is formed at the outer end of the rotating pressure plate 37 in an open manner. A through rod 24 is inserted into the oblong hole 38. An upper pulling plate 23 is arranged on the through rod 24. The upper pulling plate 23 passes through the outer end of the support plate 30, and the upper end of the upper pulling plate 23 is installed on the cross plate 2.
[0019] A rotating head 39 is installed at the inner end of the support plate 30. A rotating concave plate 40 is rotatably arranged at the upper end of the rotating head 39. A holding rod 43 is arranged at the outer end of the rotating concave plate 40. An activity hole 41 is formed in the rotating concave plate 40. A T-shaped plate 46 is inserted into the activity hole 41. An inner top plate 44 is arranged at the inner end of the T-shaped plate 46. The inner top plate 44 is located inside the rotating concave plate 40. A spring 45 is arranged at the outer end of the inner top plate 44. The outer end of the spring 45 is arranged on the outer end of the rotating concave plate 40. A vertical pulling plate 42 is arranged at the inner end of the upper moving plate 33. A bayonet is formed on the outer wall of the vertical pulling plate 42. An inner clamping head is arranged at the inner end of the inner top plate 44.
