Description

TECHNICAL FIELD

[0001] The utility model relates to guide rail flatness detection technical field especially relates to a crane guide rail flatness detection device. BACKGROUND

[0002] In the field of hoisting machinery, the guide rail flatness directly affects the stability, safety and load transmission efficiency of the crane operation. With the diversified development of industrial scenes, the specification requirements of different application scenes for the crane guide rail are significantly different, and the diversity of guide rail width, material and installation precision puts forward higher adaptability requirements for the detection device.

[0003] In the prior art, the crane guide rail flatness detection device mostly adopts fixed mechanical detection structure or single-specification roller type detection assembly. The fixed detection device is usually designed based on a specific guide rail width, and the displacement sensor or laser range finder on the rigid support is used to detect the guide rail surface at a fixed point. The mechanical structure relies on the pre-calibrated fixed reference, and the relative position of the equipment and the guide rail needs to be adjusted manually during detection, which is tedious and time-consuming. The roller type detection assembly transmits the displacement signal through the fixed width roller group in contact with the guide rail surface, and uses the mechanical linkage mechanism to convert the guide rail fluctuation into a pointer type instrument reading. Its technical principle relies on the rigid contact between the roller group and the guide rail, and is only suitable for guide rail detection with matching specifications.

[0004] However, the detection device in the prior art has significant defects. Since its mechanical structure is designed for a single-specification guide rail, it lacks self-adaptive adjustment mechanism and cannot be flexibly switched between guide rails of different widths (such as narrow tracks in the factory and wide tracks in the port). When different specifications of guide rails need to be detected, the operator needs to frequently replace the entire detection equipment or manually adjust the mechanical parameters of the fixed support, which not only leads to low detection efficiency, but also affects the accuracy of the detection results due to installation errors during equipment replacement. In addition, the provision of multiple sets of special detection equipment increases the equipment procurement cost and storage management difficulty of enterprises, seriously restricting the cross-scene adaptability and economy of crane guide rail detection. Therefore, a crane guide rail flatness detection device is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL
