Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a horizontal wheel installation structure. Background Technique

[0002] The trolley running mechanism of a bridge crane usually adopts double-flange vertical wheels. The function of the wheel flange is to guide and bear the horizontal lateral force during skewed operation; in actual operation, due to various reasons, especially for cranes with a large span, it is relatively easy to have skewed operation, resulting in serious wear between the wheels and the track. It is necessary to install horizontal guide wheels. Usually, the guide wheels on the trolley end beam are installed at the end of the end beam, which increases the length of the end beam and reduces the utilization space of the workshop.

[0003] In a crane horizontal wheel anti-drop protection installation structure disclosed in the utility model patent application publication specification CN215666670U of China, although the horizontal wheel anti-drop protection installation structure of this utility model can support and hold the horizontal wheel when the horizontal wheel falls off the wheel shaft, prevent the horizontal wheel from falling to the ground, avoid safety accidents, and can give an audible and visual alarm in time after the horizontal wheel falls off, which is beneficial to timely discovery and maintenance, and is designed with an operation notch for convenient maintenance to improve the maintenance efficiency. However, due to the fixed position of the horizontal wheel, the gap between the horizontal wheel and the track cannot be adjusted, so it is impossible to ensure that the gap between the horizontal wheel and the track is in a good matching relationship. Moreover, this horizontal wheel assembly structure can only be installed on the end beam with one track specification, and the applicable range is small. It is not convenient to adjust the position of the horizontal wheel, and at the same time, it cannot be applied to different end beams, having the disadvantage of poor applicability.
