Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, and more specifically to the technical field of a hoisting sling. Background Art

[0002] The docking water seal of the ship lift lock head seal frame bears the function of sealing and preventing water leakage when the ship chamber is connected to the outside water area. It is one of the key equipment for the safe operation of the ship lift. The water seal is vulcanized into one body by rubber segments, and the whole is U-shaped and the cross-section is curled into a C shape and installed in the docking seal frame of the upper and lower lock head working doors. The water seal is driven to act by the pushing and retracting of the seal frame, so as to achieve the function of docking and sealing the ship chamber and the lock head to prevent water leakage.

[0003] When replacing the existing C-shaped water seal of the ship lift lock head seal frame, only a sling is directly used for hoisting. After hoisting to the replacement position, the water seal is temporarily positioned by a fixture. Since the C-shaped water seal is made of rubber and is generally soft and does not have rigidity, it is easy to deform during the hoisting process. Moreover, the C-shaped water seal is a large-volume component. If deformation is found during the hoisting process, it will increase the difficulty of the overall hoisting process. On this basis, a pre-installation tooling is developed to assist the hoisting and fixing of the C-shaped water seal. The existing hoisting sling does not match well with the pre-installation tooling, and situations such as low hoisting stability are likely to occur. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting sling in order to solve the above technical problems.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0020] In one embodiment, a connection ring is arranged at the top end of the connection frame, and the connection ring is detachably connected to the suspension point plates at both ends through a shackle.

[0021] In one embodiment, a hoisting connection member is respectively arranged on the front and back sides of the left and right ends at the top of the truss. The hoisting ropes are two, one of which is connected to the two hoisting connection members on the outer sides of both ends, and the other is connected to the two hoisting connection members on the inner sides of both ends.
