Abstract
Description
Technical Field
[0001] The utility model belongs to the field of construction engineering, in particular to a fixed jacking device for a concrete placing machine of a comprehensive building. Background Art
[0002] During the concrete pouring process of high-rise buildings, traditional concrete placing booms need to be hoisted to the working floor by a tower crane with the entire concrete placing boom and its support frame before pouring each floor. This is not only heavy and requires strict selection of tower cranes, but also damages the steel bars on the working floor. In addition, due to the vibration generated during the concrete pumping process, the bottom support frame may become unstable and collapse. Traditional concrete placing booms also need to reserve holes on each floor to install pump pipes, which increases construction costs and time. Therefore, it is urgent to provide a fixed lifting device that can increase the height of the concrete placing boom of a comprehensive building to increase its working height and working range.
[0003] Chinese patent CN209780229U discloses a jacking platform system integrated with a tower crane, including a steel formwork, a pylon, a steel platform truss, a support mechanism, a power mechanism, a tower crane base, a wall attachment mechanism and a horizontal diagonal brace. A steel formwork is installed on one side of the steel platform truss, and a pylon is installed on the other side of the steel platform truss. The steel platform truss includes a pylon beam, a graded truss and a Bailey frame. The graded truss is installed around the outside, and a Bailey frame is installed inside the graded truss. Four pylon beams are symmetrically installed at the bottom of the Bailey frame. The jacking platform of this patent adopts a large-tonnage, long-stroke bidirectional oil cylinder as the power system. Although the tower crane's separate climbing process is omitted, the lifting height is limited due to its excessive weight. Utility Model Content

[0031] like Figure 1-Figure 3 As shown, the three frame fastening devices are respectively the first frame fastening device 1, the second frame fastening device 2, and the third frame fastening device 3. The upper end of the first frame fastening device 1 is connected to the body segment adding device 10, and the lower end is connected to the second frame fastening device 2 and the first hydraulic device 4 through a pin. Specifically, the first frame fastening device 1 is three H-shaped clamping claws with grooves, namely the first clamping claw 1-1, the second clamping claw 1-2, and the third clamping claw 1-3. The first clamping claw 1-1 and the third clamping claw 1-3 are connected to the second frame fastening device 2 through a pin, and the second clamping claw 1-2 is connected to the upper part of the first hydraulic device 4 through a pin. A square notch is reserved at the lower part of the long arm of the second frame fastening device 2, and the second hydraulic device 5 adjusts the amplitude of the second frame fastening device 2 so that its shape can firmly hold the frame of the body segment 19 for fixing.
