This invention relates to the field of track slab measurement, and discloses a portable track slab flatness measuring device and method. The device includes a track base, a track web at the upper end of the track base, and a track head at the upper end of the track web. Two sets of splicing clamping assemblies are provided on both sides of the upper end of the track head. One set of splicing clamping assemblies has a connecting plate at its upper end, and a laser detector at its upper end. The other set of splicing clamping assemblies has a connecting plate at its upper end, and a laser emitter at its upper end. Both sets of splicing clamping assemblies have electric wheels at their bottoms. The track base, track web, and track head are integrally formed. In this invention, the splicing clamping assemblies adopt a symmetrical clamping structure, eliminating the need to push them in from the end face of the track slab. They can be directly clamped and fixed at any position on the track head, solving the problem of limited installation position in existing devices. This facilitates accurate detection of local defects in the track slab and significantly improves detection flexibility.
