Description

Technical Field

[0001] The utility model belongs to the technical field of tower cranes and relates to a variable pre-buried foundation structure of a tower crane. Background Art

[0002] The building structure requires different lifting performance at different construction stages, and the required tower crane types are also different. If a larger tower crane is selected, the overall construction cost will increase a lot; if a smaller tower crane is selected, it will be difficult to meet the construction requirements of a certain construction stage.

[0003] The existing construction experience is to directly select a larger tower crane or make two tower crane foundations, and install different types of tower cranes according to the on-site construction requirements, which makes the construction more complicated and greatly increases the construction cost. Therefore, we propose a variable tower crane embedded foundation structure. Utility Model Content

[0007] The installation assembly includes two installation frames, both of which are arranged at the bottom of the casting box, and two installation columns are fixed on the two installation frames. Fixing rods are fixed between the four installation columns, reinforcing ribs are fixed between the four fixing rods, and installation holes are opened on the four installation columns.

[0008] With the above structure, the mounting column 1 cooperates with the fixing rod to support the tower crane, making it convenient to fix and install the tower crane.

[0009] The expansion component includes two connecting columns 1, two connecting columns 2 and four mounting columns 2. The two connecting columns 1 are respectively slidably set inside the mounting holes at corresponding positions. Two sliding holes 1 are provided on the connecting columns 2. The two connecting columns 1 are slidably set inside the corresponding sliding holes 1. Sliding holes 2 are provided above the four mounting columns 2. The mounting columns 2 are slidably set on the connecting columns 2 through the sliding holes 2. Screw holes are provided on the mounting columns 2 and the connecting columns 2. The mounting columns 2 and the connecting columns 2 are fixedly connected by bolts.

[0010] By adopting the above structure, the connecting column one is inserted into the sliding hole one, and then the connecting column two is sleeved on the two connecting columns one, and then the installation column two is sleeved on the connecting column two. After the installation column two is adjusted to a suitable position, the installation column two and the connecting column two are fixedly connected by bolts. By adjusting the positions of the installation column two and the connecting column two, the installation column two provides an installation position for tower cranes of different models.

[0011] The counterweight assembly includes an installation box, which is fixed above the casting box. A number of counterweight blocks 1 and a number of counterweight blocks 2 are arranged inside the installation box. Some of the counterweight blocks 1 have a limiting groove 1, and some of the counterweight blocks 1 are arranged above the connecting column 1 through a set of limiting grooves. Some of the counterweight blocks 1 are combined and connected by bolts, and some of the counterweight blocks 2 have a limiting groove 2. The counterweight blocks 2 are set above two connecting columns 2 through the limiting groove 2. A number of cover plates are arranged above the installation box.

[0012] With the above structure, the counterweight block 1 and the counterweight block 2 cooperate to not only limit the connection column 1 and the connection column 2, but also balance the connection column 1 and the connection column 2 to improve the stability of the installation column 2.

[0013] Compared with the prior art, this variable tower crane embedded foundation structure has the following advantages:

[0014] Through the coordination of the installation assembly, the expansion assembly and the counterweight assembly, the connecting column one is inserted into the sliding hole one, and then the connecting column two is set on the two connecting column ones, and then the installing column two is set on the connecting column two. By adjusting the positions of the installing column two and the connecting column two, the installing column two can provide installation positions for tower cranes of different models. The counterweight block one and the counterweight block two are placed in the installation box, the connecting column one and the connecting column two are limited and counterweighted, and the cover plate is fixed on the installation box. The installing column two can provide an installation base for tower cranes of different models, thereby reducing construction costs. BRIEF DESCRIPTION OF THE DRAWINGS
