[0001] The utility model relates to the technical field of shield machine construction, in particular to an anti-sway device for a segment crane. Background Art

[0002] During the construction of shield machines, segment hoisting and unloading operations are extremely critical. As an engineering operation equipment integrating excavation, soil discharge and lining, shield machines are widely used in urban underground tunnel construction, mountain crossing, underwater and other engineering projects. During the working process of shield machines, segments are the main components of tunnel lining. The efficiency and safety of their hoisting and unloading operations directly affect the progress and quality of the entire shield construction.

[0003] Since the segments are heavy, large in size and require high appearance quality, the transport platform needs to ensure good stability of the hoisting platform during transportation to reduce the shaking of the segments.

At this time, the solenoid valve 57 can be opened by the external controller. When the lifting platform 2 squeezes the tightening rod 58, the tightening rod 58 pushes the piston plate 59 to move upward, so that the hydraulic oil at the top of the hydraulic pipe 6 enters the interior of the hydraulic box 55 through the return pipe 56. In addition, when the transport platform 1 drives the lifting platform 2 to move, when the lifting platform 2 shakes during the transfer process, the auxiliary wheel 74 will be subjected to the lateral force from the lifting platform 2. This lateral force is transmitted to the tension spring 79 through the connecting frame 72 and the fixed shaft 75. The tension spring 79 generates a reverse pulling force on the connecting frame 72 through its elastic force, thereby offsetting the shaking of the lifting platform 2 and maintaining its stable state.
