Description

Technical Field

[0001] This utility model belongs to the technical field of tower crane bases, and in particular relates to a split-type tower crane base. Background Technology

[0002] With the rapid development of the modern construction industry, high-rise and super high-rise building projects are increasing. As the core lifting equipment on the construction site, tower cranes are responsible for lifting various construction materials such as steel bars, concrete, and steel pipes. Split tower crane bases, with their modular combination characteristics, have shown significant advantages in installation flexibility and material utilization, and have gradually become an important alternative to traditional integral bases. Therefore, a structurally reasonable and reliable split tower crane base is needed to adapt to tower crane equipment and ensure the safety and efficiency of the construction process.

[0003] However, existing tower crane bases are not convenient for the rapid assembly and disassembly of key components, making them difficult to install and disassemble, thus prolonging the installation and dismantling period and reducing construction flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide a split tower crane base. By setting up a quick-assembly and disassembly part, it solves the problem that existing tower crane bases are not convenient for quick assembly and disassembly of key components during use, which makes it difficult to disassemble and reassemble the tower crane base, thereby prolonging the installation and dismantling period and reducing construction flexibility.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a split-type tower crane base, comprising a base plate and further comprising: a support portion disposed on the base plate; a plurality of quick-assembly / disassembly portions arranged in a circular array above the base plate; a guide portion disposed on the base plate; each quick-assembly / disassembly portion includes a snap-fit ​​assembly disposed on the base plate; an insertion assembly disposed on the base plate; the snap-fit ​​assembly includes a hexagonal box disposed on the base plate, a sliding rod passing through the hexagonal box and slidably connected to the hexagonal box; a slider slidably connected to the inner wall of the hexagonal box, the slider having an elastic element disposed thereon; the sliding rod passing through and fixedly connected to the slider; the elastic element including a spring fixedly connected to the front side of the slider, the front side of the spring being fixedly connected to the inner wall of the hexagonal box.

[0007] Furthermore, the insertion assembly includes a slot formed on the support column, the inner wall of the slot being provided with an L-shaped rod, the inner wall of the slot contacting the L-shaped rod; a sliding rod passes through the L-shaped rod and contacts the inner wall. Furthermore, the support portion includes several support columns disposed on the top of the base plate, the sliding rod being slidably connected to the corresponding support column; the rear side of the hexagonal box is fixedly connected to the corresponding support column.

[0008] Furthermore, the guide portion includes a guide assembly disposed on a corresponding support column; and a connecting assembly, of which two connecting assemblies are provided and installed on the corresponding support column. The guide assembly includes a guide block fixedly connected to the top of the L-shaped rod, and a guide groove is formed on the top inner wall of the slot. The guide block is adapted to the guide groove, and the guide block is located in the guide groove and in contact with the inner wall.

[0009] Furthermore, the connecting assembly includes a connecting rod disposed on an L-shaped rod, through which two bolts pass, the outer walls of the two bolts contacting the inner wall of the connecting rod, and the outer walls of the two bolts being threaded with nuts. The corresponding bolts pass through the L-shaped rod, and the outer walls of the corresponding bolts contact the L-shaped rod. The connecting rod is used to connect two adjacent L-shaped rods of quick-release parts.

[0010] This utility model has the following beneficial effects:

[0011] 1. By setting up a quick-assembly and disassembly section, during operation, the sliding rod is first pulled to the side away from the support column, which drives the slider to compress the spring, causing one end of the sliding rod to disengage from the slot. Then, the L-shaped rod is inserted into the slot. After the guide block and guide groove are in place, the sliding rod is released. The spring rebounds and drives the sliding rod to reset through the slider and pass through the L-shaped rod, thus completing the fixation of the L-shaped rod. During disassembly, the sliding rod can be pulled in the opposite direction to remove the L-shaped rod. The significance of this is that through mechanical buckles and elastic reset structure, the key components of the tower crane base can be quickly assembled and disassembled, which greatly shortens the installation and disassembly period, solves the problem of the difficulty in disassembling and assembling traditional tower crane bases, and improves construction flexibility.

[0012] 2. By setting up a guide unit, during operation, as the L-shaped rod is inserted into the slot, the top guide block slides along the guide groove, providing precise guidance for the installation of the L-shaped rod and ensuring that the sliding rod and the through hole of the L-shaped rod are precisely aligned; after the L-shaped rods of multiple quick-assembly and disassembly parts are fixed, the adjacent L-shaped rods are attached to the connecting rod, bolts are inserted and nuts are tightened to realize the connection and fixation of adjacent supports. Its significance lies in ensuring the accuracy of component installation through the guide component, avoiding assembly deviations from affecting structural stability, and forming a whole load-bearing structure through the connecting component, ensuring the safety and stability of the tower crane during operation.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Then, place another support column 112 at the corresponding position on the top of the base plate 111, and similarly install the L-shaped rod 222 on it. Then, place the connecting rod 321 on the front side of the two L-shaped rods 222, align the reserved holes on them, insert the bolt 322 and tighten the nut 323. Similarly, fix the other connecting rod 321, thus completing the connection between the two L-shaped rods 222, that is, connecting the two support columns 112. The same process as above can complete the connection and fixation of these two support columns 112 and other support columns 112, thus completing the assembly of the four support columns 112 in the separated state. And through the above reverse process, their separation can be completed.
