Description

Technical Field

[0001] The utility model relates to the technical field of crane beam equipment, in particular to a connecting device for a steel crane beam and a walkway plate. Background Art

[0002] In the industrial workshop of the factory, there are crane beams for lifting and hoisting equipment or goods. In order to allow people to access the crane, a walkway board for accessing the crane beam will be installed. The walkway board must be connected to the crane beam on site after the crane beam is installed. In the prior art, the connection between the walkway board and the crane beam is generally welding or bolting, and the installation process requires on-site operation. Since on-site operations are required and the factory building is relatively large, the operation time of personnel is relatively long. In order to ensure the reliability and safety of the connection and fixation of the walkway board; when using a welded structure, in order to ensure a good welding effect and ensure the safety and reliability of the welding part, the metal surface of the welding part needs to be cleaned before welding, and protective materials such as rust and coating need to be removed. Pretreatment work such as pretreatment to ensure that the welding area is dry and clean, and when welding, it is necessary to strictly control appropriate welding parameters and select appropriate welding materials. When bolted structures are used for connection, it is necessary to process the bolt connection holes in advance. Bolt connections are generally 200 or 300 mm per bolt, which requires a lot of bolts. A factory building of dozens or hundreds of meters requires a lot of bolts and the installation workload is large. The labor intensity of the operator is high and the work efficiency is low. In addition, there will be a protruding small nut in the bolt connection, which will cause unsafe factors that crane users are prone to tripping at high altitudes. High-altitude operations are inconvenient, the working hours are long, and there are more safety hazards. Utility Model Content

The vertical movement of the clamping plate 4 is achieved by the axial movement of the connecting nut 5 on the stud 3 to achieve the clamping and loosening of the walkway plate 2 and the crane beam 1. The stud 3 is welded to the bottom of the walkway plate 2 before installation.

[0037] Example 3

[0038] Different from the second embodiment, the locking mechanism 3 adopts an independent detachable structure, and the locking mechanism of the detachable structure is used to achieve the clamping and loosening of the walkway plate 2 and the crane beam 1.

[0040] The locking mechanism 3 of the detachable structure includes an upper horizontal connecting plate 31, a lower horizontal connecting plate 32, a vertical connecting plate 33, a locking stud 35, a connecting nut 34, and a clamping plate 36. The upper end of the vertical connecting plate 33 is connected to one end of the upper horizontal connecting plate 31, and the lower end of the vertical connecting plate 33 is connected to one end of the lower horizontal connecting plate 32.
