[0002] Tower cranes are the most commonly used lifting equipment on construction sites. Also known as "tower cranes," they are constructed by extending (height) sections (referred to as "standard sections") to lift construction materials such as steel bars, timber, concrete, and steel pipes. Tower cranes are an indispensable piece of equipment on construction sites.

[0003] Patent No. CN203022020U provides a steel structure frame tower crane foundation. This patent solves the shortcomings of the main concrete foundation unit, transition concrete foundation unit, and end concrete foundation unit requiring special molds during the cast-in-place concrete process, and requiring a large number of molds to be made. At the same time, it also solves the substantial technical problems of occupying too much cargo space during supply and transportation, excessive total weight, and high freight costs caused by the need for high load-bearing capacity for long-distance transportation. It has the advantages of novel structure, high safety performance, convenient disassembly and assembly, and convenient transportation.

[0004] However, when using this patent for fixed connection, the deviation between the position of the base unit and the expected position affects the fixation of the structure and increases the workload; at the same time, during transportation, due to the large number of bolts and other parts, they are prone to loss and damage. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a steel structure frame tower crane foundation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel structure frame tower crane foundation, comprising a main body, a fixing mechanism and a storage mechanism, wherein the main body includes a main concrete foundation unit, the outer wall of the main concrete foundation unit is connected to a transition concrete foundation unit, and one end of the transition concrete foundation unit is connected to an end concrete foundation unit;

[0007] The fixing mechanism includes a fixing plate connected to the outer wall of the main concrete foundation unit, a support plate connecting two adjacent fixing plates, a connecting groove provided inside the transition concrete foundation unit, the end concrete foundation unit and the fixing plate, a connecting rod connected to the inner wall of the connecting groove, a buckle connected to the inner wall of the connecting rod, and threaded holes provided inside the transition concrete foundation unit, the end concrete foundation unit and the fixing plate, with bolts connected to the inner wall of the threaded holes.

[0008] Preferably, the storage mechanism includes a storage groove located inside the end concrete foundation unit, a storage plate connected to the inner wall of the storage groove, a slider located on one side of the storage plate inside the end concrete foundation unit, a spring connected between the slider and the end concrete foundation unit, and a push plate connected to the inner wall of the spring.

[0009] Preferably, the inner wall of the connecting groove fits into the outer wall of the connecting rod.

[0010] Preferably, the connecting rod is provided with a "T"-shaped slot, and the outer wall of the buckle fits into the inner wall of the "T"-shaped slot.

[0011] Preferably, the inner wall of the threaded hole is provided with an internal thread, the outer wall of the bolt shank is provided with an external thread, and the internal thread of the threaded hole and the external thread of the bolt are matched.

[0012] Preferably, the storage plate and the storage slot are connected by a rotating shaft.

[0013] Preferably, one end of the storage plate has a slot inside the storage plate, and the inner wall of the slot fits with the outer wall of the slider.

[0014] Preferably, one end of the slider is an inclined surface, the inner wall of the slider has a square structure, and one end of the push plate is in contact with one end of the inner wall of the slider.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention uses a fixed plate and a connecting rod to attach the transition concrete foundation unit to the main concrete foundation unit along two parallel and adjacent fixed plates. The end concrete foundation unit is placed at one end of the transition concrete foundation unit. The connecting rod is passed sequentially through the connecting groove in the end concrete foundation unit, the transition concrete foundation unit, and the fixed plate. The connecting rod is fixed by snapping against the inner wall of the connecting rod, thereby completing the pre-fixation of the tower crane foundation. This facilitates pre-fixation when fixing the tower crane foundation, avoiding the impact of positional deviation of the foundation unit on the connection.

[0017] This invention uses a push plate. Pushing the push plate causes the slider to move until it moves out of the slot of the storage plate, opening the storage plate. Bolts and other parts are then placed into the storage slot. Rotating the storage plate causes it to contact the slider, which in turn moves the slider until it contacts the slot of the storage plate. The slider is then pulled into the slot by the elastic force generated by the spring deformation, thus fixing the storage plate in place. This facilitates the storage of small parts such as bolts during transportation, preventing loss and damage during the process. Attached Figure Description
