Disclosed is a pallet fork mechanism matched with an electric power engineering construction repair and recovery vehicle. The pallet fork mechanism mainly comprises two outer pallet fork slides which are arranged on a pallet fork fixing plate in a parallel mode; the inner side of each outer pallet fork slide is provided with a plurality of bearing rolling sleeves which pass through a bearing fixing shaft; a middle pallet fork slide is closely next to the inner side of the corresponding outer pallet fork slide and sleeves the bearing rolling sleeves through below sliding grooves to move in an extensible mode; an inner pallet fork slide is closely next to the inner side of the corresponding middle pallet fork slide; one lateral side of each inner slide, which is adjacent to the corresponding middle pallet fork slide, is provided with a plurality of bearing rolling sleeves which pass through the bearing fixing shaft; sliding grooves formed below one side of each middle pallet fork slide sleeve the bearing rolling sleeves to move in an extensible mode. According to the pallet fork mechanism matched with the electric power engineering construction repair and recovery vehicle, the structure is simple, the use is safe and reliable, and electric power devices such as transformers can be placed and safely fixed conveniently to be rapidly conveyed to the accident site through the repair and recovery vehicle for accident repair and electric power device replacement.
