Description

Technical Field

[0001] This utility model relates to the field of support erection, and in particular to a prefabricated support for tower cranes. Background Technology

[0002] Existing tower crane supports use round tubes as the main building material, and their overall structure is formed by welding these round tubes together. Starting from the bottom of the support, the round tubes are sequentially welded upwards to the top, forming a complete support structure. In this structural design, all connections between the round tubes are fixed by welding, and welding is an ongoing process throughout the entire tower crane support erection process, whether for horizontal or vertical tube combinations.

[0003] Existing tower-building machine supports rely heavily on welding, resulting in low production efficiency and long production cycles due to the numerous welding points. Furthermore, post-weld processes such as quality inspection and grinding further increase production time and costs, making it difficult to meet the demands of large-scale production. Extensive welding not only consumes a large amount of welding materials but also increases production costs due to the maintenance and replacement of welding equipment. Moreover, the extensive welding work exposes operators to hazardous environments for extended periods, posing significant safety risks. Additionally, existing tower-building machine supports use round pipes as the primary structural material. The need for expansion joints to connect the lateral formwork of the beams, coupled with the round pipe material, necessitates welding these joints to the supports. This welding method is difficult and results in unstable installations, and the expansion joints are also difficult to reuse. Utility Model Content

[0004] This utility model provides an assembled support for tower building machines, which solves the problems of low production efficiency, high production cost, and high safety risks caused by using a large number of round tubes as the main building material for tower building machine supports and connecting them by welding. The expansion joints are difficult to install by welding them to the round tubes, resulting in unstable installation. At the same time, the expansion joints are difficult to reuse.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an assembled support for a tower-building machine, including a main support and a side support. The main support includes multiple vertical tube arrays, each vertical tube array including four vertical tubes.

[0011] In a preferred embodiment, the adjusting screw includes two U-shaped frames, each with a threaded sleeve, and a bidirectional screw is provided between the two U-shaped frames, with the bidirectional screw connected to the threaded sleeves of the two U-shaped frames respectively.

[0012] In the preferred embodiment, one of the U-shaped frames is connected to the horizontal square tube, and the other U-shaped frame is connected to the vertical square tube.

[0013] In the preferred embodiment, the telescopic mechanism includes a U-shaped bracket, with both sides of the U-shaped bracket connected to a vertical square tube. A sliding I-beam is provided on the U-shaped bracket, and a pin seat is provided on the I-beam. A telescopic cylinder is provided on the U-shaped bracket, with one end of the telescopic cylinder connected to the pin seat, and one end of the I-beam having a receiving end.

[0014] In the preferred embodiment, a second truss is provided on the side support, the second truss has the same structure as the truss, the main support has the same structure as the side support, and multiple connecting square tubes are provided between the main support and the side support.

The vertical tubes 301, horizontal tubes 4, and connecting square tubes 7 are all square tube structures, allowing for rapid assembly. The two ends of the adjusting screws 6 are U-shaped frames 601, which can also be quickly connected to the vertical tubes 301 and horizontal tubes 4, greatly saving the assembly time of the entire device.

[0029] The two vertical square tube arrays 3 are connected by a connecting node 5, which includes four inner square tubes 501. The connecting node 5 is connected to the horizontal square tubes 4 via support plates 504, which also allows for rapid assembly and saves construction time.

This avoids the problems of long production cycles, difficulty in meeting large-scale production needs, high consumption of welding materials, high production costs, and high safety risks caused by a large number of welding points.

[0030] The overall structure uses square tubing. The U-shaped bracket 801 of the telescopic mechanism 8 can abut against the vertical square tube 301, which is also a square tubing structure, so that the telescopic mechanism 8 can be installed quickly and stably. The installation method is firm and avoids the phenomenon of the telescopic mechanism 8 being connected to the bracket by welding. The U-shaped bracket 801 is connected to the vertical square tube 301 by bolts, so that the telescopic mechanism 8 can be quickly disassembled after use and can be reused.

[0031] In a preferred embodiment, the main support 1 includes multiple base plates 9, on which multiple trusses 10 are mounted. Each truss 10 has multiple protruding tubes 1001 connected to a vertical square tube 301.
