Technical Field

[0001] The present application relates to the technical field of tower crane structures, and in particular to a cable-type stabilization system for cranes. Background Art

[0002] Recently, in the installation and construction of wind power engineering equipment, large-tonnage crawler cranes have been gradually replaced by tower cranes; large tower cranes have high installation efficiency, fast transfer, and are safe and reliable. This is also a type of installation equipment that is more recognized by the wind power industry; wind power equipment installation generally requires a very short construction period, which requires not only high installation and disassembly efficiency of the lifting equipment itself, but also to overcome many safety and reliability issues. Among them, the stability of the tower body is self-evident. When the lifting tonnage is large, the tower body is prone to tilt. At this time, it is necessary to add a connecting structure between the middle section of the tower body and the wind power tower, which greatly increases the difficulty of lifting construction and makes it difficult to achieve rapid installation and disassembly. This application makes improvements to this. Summary of the invention

[0003] The purpose of the present application is to provide a cable-type stabilization system for a crane, which eliminates the additional reinforced connection structure between the tower body and the wind turbine tower, and adopts a cable structure to pull the top of the tower body from multiple directions. During hoisting, the tower body's own rigidity, the bottom support rod group and the cable trinity maintain the stability of the tower body, and the reliability and safety are significantly improved. At the same time, the on-site construction does not involve an additional reinforced connection structure between the tower body and the wind turbine tower, and the installation and disassembly are relatively convenient, and the hoisting task can be completed within a relatively short construction period.

[0004] In order to solve the technical problems in the prior art that the installation and disassembly of the tower body in wind power hoisting operations is laborious and the stability is not strong, the present application provides a cable-type stabilization system for a crane, which includes a tower body, a cable sleeve, cables and a plurality of foundation blocks; the plurality of the foundation blocks are respectively arranged around the tower body, and a support rod group is arranged between the tower body and the foundation blocks; the cable sleeve is sleeved on the tower body, and the cables are respectively connected between the plurality of the foundation blocks and the cable sleeve.

[0007] Furthermore, the present application provides a cable-type stabilization system for a crane, wherein the tensioning mechanism includes a tensioning motor and a winding disk, the tensioning motor is installed on a foundation block through a base, the winding disk is sleeved on the output shaft of the tensioning motor, and the cable is wound around the winding disk.

[0008] Furthermore, the present application provides a cable-type stabilization system for a crane, wherein a ratchet disc is provided on the side of the winding disc away from the tensioning motor to limit the winding disc from loosening.

[0009] Furthermore, the present application provides a cable-type stabilization system for a crane, wherein the cable sleeve extends a plurality of extension arms in a direction away from the tower body, and the pulley is installed at the end of each extension arm.

[0010] Furthermore, the present application provides a cable-type stabilization system for a crane, wherein the support rod group suspends the tower body.

[0011] Furthermore, the present application provides a cable-type stabilization system for a crane, wherein the support rod group includes an automatic leveling hydraulic cylinder, a horizontal support beam and a diagonal support rod, the automatic leveling hydraulic cylinder is installed on a foundation pad, the outer end of the horizontal support beam is fixed to the piston rod end of the automatic leveling hydraulic cylinder, and the inner end is hinged to the bottom of the tower body, the outer end of the horizontal support beam is welded and fixed to a hinge plate, the outer end of the diagonal support rod is hinged to the hinge plate, and the inner end is diagonally supported on the tower body and hinged to the tower body.

[0012] Compared with the cranes in the prior art, the present application has the following advantages: the present application innovatively adds a pulley cable structure, which cooperates with the inclination sensors arranged at the four corners of the tower body. When a slight tilt in a certain direction is sensed, the corresponding tensioning motor is instructed to wind the cable to maintain the stability of the tower body, thereby significantly improving the reliability and safety. At the same time, on-site construction does not involve additional reinforced connection structures between the tower body and the wind turbine tower, and installation and disassembly are relatively convenient, so the lifting task can be completed within a shorter construction period.
