Description

Technical Field

[0001] The utility model relates to the technical field of walkway plate processing, in particular to a walkway plate splicing fixture. Background Art

[0002] As an operating platform for construction machinery vehicles, the walkway is mainly arranged on the crane frame, located on both sides of the crane chassis, and plays a role in bearing and protecting the vehicle, while facilitating the walking and operation of operators. Since pedestrians or related components are needed above the walkway, the walkway is required to have a certain strength and maintain its surface flatness to make the operation safer and more reliable.

[0003] When existing walkways are spliced ​​and installed, a hook is usually used to hook the side light installation hole on the side of the walkway, and then the walkway is vertically hoisted onto the sub-frame and one side of the walkway is made to contact the sub-frame. After one side of the walkway is in contact with the sub-frame, the height of the hook is lowered to slowly adjust the walkway to a horizontal position. However, due to the different lengths of existing walkways, the distance of the hooks needs to be frequently adjusted during hoisting, and the stability is poor during the hoisting process, posing a safety hazard.

[0004] Based on this, we propose a walkway splicing fixture. Utility Model Content
