Description

Technical Field

[0001] The utility model relates to the technical field of jacking machines, in particular to a jacking machine base structure. Background Art

[0002] The jacking machine of the standard section of the tower crane is a key part of the tower crane, which is used to adjust the height of the tower crane. It mainly relies on the hydraulic system and the electric motor to complete the jacking work. During the jacking process, the motor provides power to drive the reducer to operate. The reducer reduces the output speed of the motor and transmits the torque to the hydraulic pump. The hydraulic pump converts electrical energy into hydraulic energy and delivers high-pressure oil to the hydraulic cylinder. The hydraulic cylinder uses the flow and pressure of the oil to achieve jacking. When the high-pressure oil enters the hydraulic cylinder, the piston moves upward under the action of the force, thereby achieving the jacking of the tower crane.

[0003] After searching, a Chinese patent with publication number CN207226920U discloses a tower crane lifting mechanism. As the platform assembly is far away from the position to be installed of the standard section in the vertical direction, after the newly added standard section is lifted onto the platform assembly, it is necessary to lift the newly added standard section to the height of the position to be installed by a secondary lifting through the lifting and traction beam installed above, and then transport the newly added standard section to the upper layer of the original standard section by the trolley on the lifting and traction beam for connection. The secondary lifting is not only complicated to operate, but also requires the operator to keep the newly added standard section stable and align it when installing the new standard section, which makes the installation difficult. Therefore, a traction frame is used to guide the newly added standard section to move to the top of the original standard section at the bottom of the lifting frame and align it to the position. Compared with lifting, it has a more stable effect and reduces the difficulty of installation operation for the operator.

[0004] There are still some shortcomings in the use of the above-mentioned jacking machine. The jacking machine base is one of the important components of the jacking machine. It is the bottom structure that supports the entire jacking machine and the upper jacking load. The traditional jacking machine base only supports the jacking machine and the upper load, and cannot realize the overall movement of the jacking object driven by the base. It has low versatility and slow lifting speed. Utility Model Content
