Problems solved by technology
This method often occurs during the installation of large tower cranes. Although the installer does not need to hold it with his hands to reduce injuries, tower crane installation is a dangerous high-altitude operation. The installer pulls the hemp rope in the sky To support the pin shaft, it is difficult to align the pin shaft with the center line of the pin hole, which increases the difficulty of driving the pin shaft; in addition, the hemp rope covers the pin shaft, and the pin shaft itself is relatively smooth. It is easy to slip and fall, causing safety accidents

The invention discloses a hinge pin assembling aid for a tower crane. A first end of a supporting plate (1) is fixedly connected with a main body structure of the tower crane and is positioned below a hinge pin hole; and when a hinge pin is placed on the supporting plate (1), the center line of the hinge pin and a center hole of the hinge hole are positioned on the same straight line. Round steel bars (2) are respectively welded to two sides of the inner wall of the supporting plate (1), the hinge pin is supported on the two steel bars (2), so that a gap is formed between the hinge pin and the supporting plate (1), and a safe distance is reserved. The hinge pin assembling aid for the tower crane is provided with a semi-cylindrical support body which supports the hinge pin, the center line of the hinge pin is aligned with the center line of the hinge pin hole, the semi-cylindrical support body has a protecting function in hinge pin assembling and disassembling processes, so that an assembling worker is safe, and potential safety hazards are effectively avoided. In addition, the hinge pin assembling aid has the characteristics of simple structural form and convenience in production, machining, assembly and disassembly.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a pin auxiliary installation device of a tower crane. Background technique [0002] Due to the increase in lifting performance and main structure size of tower cranes, the size and weight of the connecting pins between the structural parts also increase, and the installation difficulty of the pins increases. During the installation process of the tower crane, the installer needs to hold the pin shaft to the pin hole first. Because the weight of the pin shaft is too heavy, it often encounters dozens or even hundreds of kilograms, and the installer cannot hold the pin shaft at all; It is a high-altitude operation, and the pin shaft and the pin hole of the main structure cannot be driven in if the pin hole is not aligned; sometimes in the process of pinning the pin shaft, the pin shaft is not fixed and easy to slip, resulting in safety accidents. [0003] In the exist...
