[0001] The utility model relates to the technical field of construction engineering unloading devices, in particular to a construction steel structure engineering cutting and unloading device. Background Art

[0002] Modern architecture is becoming more diverse, and the number of buildings that use steel structures as their main body is increasing. When the building steel structure adopts temporary support towers and segmented lifting construction technology, after the structure is assembled, the steel structure must be unloaded first before the temporary support tower can be removed, and the structural design is officially completed.

[0003] The existing cutting and unloading devices for building steel structure engineering usually cannot make the inclined steel structure evenly stressed, and cannot clamp the unloaded steel structure, which makes the steel structure easy to slip from the unloading device. Therefore, we propose a cutting and unloading device for building steel structure engineering. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the existing equipment that usually cannot make the inclined steel structure evenly stressed and cannot clamp the unloaded steel structure, which causes the steel structure to easily slide off the unloading device, and proposes a construction steel structure engineering cutting and unloading device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, a first transmission rod is fixedly connected to the output shaft of the first motor, the first transmission rod is rotatably connected to the base, and a forward-rotating screw and a reverse-rotating screw are fixedly sleeved on the first transmission rod.

[0008] Preferably, the lifting mechanism includes two sliders and four lifting rods, the sliders are slidably connected to the base, and the two sliders are respectively threadedly connected to the forward screw and the reverse screw, and the lifting rods are rotationally connected to the sliders and the lifting block.

[0009] Preferably, the tilting mechanism comprises a plurality of springs and a receiving frame, the springs are fixedly connected to the bottom inner wall of the annular groove, and the receiving frame is fixedly connected to the springs.

[0010] Preferably, the clamping mechanism comprises two clamping screws, two threaded sleeves and two anti-slide plates, the clamping screw fixed sleeve is arranged on the third transmission rod, the threaded sleeve is threadedly connected to the clamping screw, and the threaded sleeve is fixedly connected to the anti-slide plate.

[0012] Preferably, the receiving frame is fixedly connected to the square supporting block, and a fixing rod is fixedly connected between two lifting rods located on the same side.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] (1) In this solution, since multiple springs and receiving frames are provided, when the groove in the square support block contacts the inclined steel structure, the multiple springs and receiving frames can make the square support block fit the inclined steel structure more closely, so that the force on the square support block is more even.

[0015] (2) In this scheme, since a clamping screw, a screw sleeve and an anti-slide plate are provided, the threaded connection between the clamping screw and the screw sleeve drives the screw sleeve to move, and the screw sleeve drives the anti-slide plate to move.
