Description

Technical Field

[0001] This utility model relates to the technical field of H-section crane beams, specifically to an auxiliary positioning device for installing H-section crane beams. Background Technology

[0002] H-section crane beams are a common type of crane beam. The cross-sectional shape of an H-shaped crane beam resembles an "I" shape, but the width and thickness of the upper and lower flanges are usually equal. The thickness of the web in the middle is the same as that of a standard steel plate, while the width of the web depends on the required load. This cross-sectional shape has a large moment of inertia, effectively resisting bending moments, while the presence of flanges increases the torsional resistance of the section.

[0003] In current technology, when installing steel beams at high altitudes, operators need to hold the beam while using bolts and nuts to install it in the desired position. However, before installing the bolts, operators need to manually align the holes on the steel beam with the holes at the desired positions. After alignment, they need to hold the beam and then use bolts and nuts to install it in the desired position. Because the steel beam is heavy, it is easy for the beam to shift while aligning and tightening the nuts. Therefore, it is particularly important to improve the existing installation device and design a new H-section crane beam installation auxiliary positioning device to solve the above-mentioned technical defects and improve the practicality of the overall installation device. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary positioning device for the installation of H-shaped cross-section crane beams. Through the design of a fixing block, a limiting block, and a positioning groove, the crane beam is displaced, allowing the positioning rod to be inserted into the positioning groove and positioned with the installation steel beam. This initial connection between the crane beam and the installation steel beam frees the operator's hands. Rotating the bolts moves the fixing block, inserting it into the fixing groove and limiting its connection with the crane beam. This allows the connecting plate to also be limited in its connection with the crane beam. Rotating the inner and outer nuts moves the device towards one end of the connecting frame, allowing the limiting block to contact the crane beam. This connects the connecting groove to the top of the crane beam, further limiting its position. This makes the crane beam more stable and precise during high-altitude installation, thus solving the problems mentioned in the background art.
