[0002] Tower cranes are commonly used lifting equipment in construction companies. They are mainly used to lift building materials such as steel bars, concrete, and steel pipes. The metal structure of a tower crane consists of a jib, tower body, turntable, support, counterweight boom, base frame, and tower top. The base frame is an important component of the tower crane. It is the load-bearing foundation of the entire tower crane and its function is to transfer the weight of the entire tower crane to the ground. Usually, the base of a tower crane is a fixed structure, and it can only be matched with a fixed model of tower crane in use.

[0003] An existing technology, patent application number 202321129258.2, describes an assembled tower crane base, including a base and a clamping seat. Four sets of clamping seats are evenly spaced on the outer wall of the base. Each clamping seat has an adjusting rail inside, with one end extending to the outside of the clamping seat. A support seat is installed at the end of each adjusting rail away from the clamping seat, and a ground spike is installed at the bottom of each support seat. A column is installed at the top of each adjusting rail, and two sets of support sleeves are installed on the outer wall of each column. This design not only allows for free sliding adjustment and assembly of the tower crane base, facilitating control and adjustment at different spacings and positions, and enabling adjustable support for different types of tower cranes, but also improves the stability of the structural connection and the convenience of assembling and fixing the tower crane base. However, the lower fixing surface of the tower crane is only fixed on one side, resulting in relatively poor stability of the tower crane column installed on the lower base. Utility Model Content

[0006] Furthermore, the first limiting hole is configured as an arc-shaped groove, and the lower end of the stable support slides through the first limiting hole.

[0007] Furthermore, the stabilizing support plate has a first positioning hole inside, and the first positioning plate has a second positioning hole inside.

[0008] Furthermore, the stable support plate is provided with a third limiting hole inside, and the upper wall of the stable support is provided with a second limiting hole.

[0009] Furthermore, the outer sides of both ends of the transverse limiting plate are provided with positioning sleeves, the lower end of the positioning sleeve is provided with a locking bracket, and the upper side of the positioning sleeve is provided with a locking bolt.

[0010] Furthermore, the locking bracket is configured as an L-shaped bracket, and one end of the locking bracket is engaged with the limiting groove on the lower outer wall of the stable support.

The lower end of the tower crane column is inserted into the mounting groove on the upper part of the stable support through a stable support plate, so that the lower end forms a multi-faceted surrounding fixation, which increases the installation support area between the tower crane column and the lower base, which is conducive to improving the stability of the tower crane column installed on the lower base. Moreover, the stable support plate and the stable support are laterally inserted and limited by a transverse limiting plate, which can improve the stability of the installation and fixation between the stable support plate and the stable support, thereby facilitating the improvement of the stability of the installation and fixation between the tower crane column and the stable support.

[0013] 2. This utility model utilizes a positioning sleeve that slides on the outer sides of both ends of the transverse limiting plate. A locking bracket is provided at the lower end of the positioning sleeve. One end of the locking bracket engages with the limiting groove on the lower outer wall of the stable support. This allows the transverse limiting plate to be fixed to the outside of the lower base using the locking bracket and the positioning sleeve, thereby improving the stability of the stable support plate and the stable support and the lower base during installation.
