Description

Technical Field

[0001] The utility model relates to the technical field of tower crane installation, in particular to a tower crane pre-buried base leveling mechanism. Background Art

[0002] Tower crane is a commonly used equipment in the construction field. The overall mass of the tower crane is large and the height is high. In order to enhance stability, the tower crane base needs to be installed on a concrete foundation. However, the precision of the concrete foundation is low, and its surface is difficult to be completely horizontal, which ultimately affects the verticality of the tower crane. Even a slight tilt of the tower crane will greatly affect its stability in use. The tower crane base in the prior art cannot be leveled without being installed. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a tower crane pre-embedded base leveling mechanism which is convenient for adjusting horizontality and improving the installation stability of the tower crane.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] During installation, the first embedded part is first embedded by pouring cement, and then the second embedded part and the base body are installed after solidification. After the base body is installed, the levelness of the base body is adjusted with the help of a spirit level. During adjustment, the upper end height of the second embedded column is adjusted separately by rotating the adjusting sleeve. After the base body is leveled, cement is poured to cast all the parts below the upper support seat of the second embedded part so that the second embedded part is buried in the cement. At this time, the base body is in a horizontal state, and finally the tower crane is installed on the base body.

[0007] Preferably, a plurality of anchor columns are provided at the bottom of the first embedded component, and the anchor columns make the installation of the first embedded component more stable.

[0008] Preferably, the top surface of the adjustment seat is configured as a support surface, and a wrench seat is fixedly provided at the lower end of the adjustment seat. The support surface is used to support the lower support seat, and the wrench seat can rotate the adjustment seat with the help of a wrench, which is more convenient to use.

[0009] Preferably, the second embedded part is a columnar structure, the cross section of the second embedded part is a rectangular structure, a plurality of pressure plates distributed vertically are fixed on the second embedded part, and reinforcing ribs are arranged between the top surface of the pressure plate and the four side surfaces of the second embedded part. After the second embedded part is embedded, the pressure plate is used to bear the pressure from top to bottom.

[0010] Preferably, the upper end of the upper support seat extends upward to form a docking post, and the bottom surface of the connecting seat is provided with a docking hole for plugging with the docking post. The docking post is inserted into the docking hole to form a plug-in connection, and then locked by bolts and nuts, so that the connection and positioning are more stable and reliable.
