Problems solved by technology
In this invention, double cylinders are installed for simultaneous jacking. Although the center of gravity of the jacking can be evenly dispersed, there is still the problem that the jacking cylinder is easily deformed by the lateral force, and the jacking cylinder is not easy to maintain and replace.

The invention relates to the technical field of tower cranes, and discloses a tower crane three-oil-cylinder jacking device which comprises a jacking outer sleeve frame, a jacking supporting device and jacking oil cylinders, the three jacking oil cylinders are arranged on the two opposite sides of the jacking outer sleeve frame, and the three jacking oil cylinders are located at the three vertex positions of an isosceles triangle; the two jacking oil cylinders located on the same side are arranged corresponding to the stand columns of the rectangular frame, and the tops of cylinder bodies of the two jacking oil cylinders are fixed to the stand columns through fixing blocks and first hoops. The single jacking oil cylinder located on the other side is fixed to a cross beam of the jacking outer sleeve frame. The cross beam at least comprises a bottom beam and a top beam, a bearing piece is arranged on the bottom beam, a through hole is formed in the bearing piece, the top beam is disconnected from the corresponding position of the single jacking oil cylinder so that the single jacking oil cylinder can smoothly penetrate to the position above the top beam, and the single jacking oil cylinder and the top beam are fixed through a second clamp. The problem of deformation of the jacking oil cylinder is effectively solved, the jacking oil cylinder is more convenient to disassemble and assemble, and later maintenance and replacement are facilitated.
Description
technical field [0001] The invention relates to the technical field of tower cranes, in particular to a three-cylinder jacking device for tower cranes. Background technique [0002] With the continuous progress of society, large-scale real estate is constantly being built, and the tower crane industry is also booming. Tower crane, also known as tower crane, is a piece of equipment used to lift steel bars, wooden corrugated, concrete, steel pipes and other raw materials used in construction. [0003] In the prior art, in common tower cranes, the climbing device generally adopts a single jacking oil cylinder design. For example, a Chinese utility model patent with a publication number of CN213923820U discloses a climbing device for a tower crane with a jacking and anti-falling function, which includes: a standard section, the outer wall of the standard section is slidably connected to the top plate of the climbing frame, and the outer wall at the bottom of the top plate of th...
