The invention discloses a suspension rail platform with a support. The suspension rail platform comprises a platform assembly, supporting mechanisms, a plurality of driven wheel assemblies, a connecting rod assembly and a slewing bearing mechanism. The top of the platform assembly is provided with the driven wheel assemblies which are in rolling connection with a suspension rail. The supporting mechanisms comprises the left supporting mechanism, the right supporting mechanism, the upper supporting mechanism and the lower supporting mechanism, and the left supporting mechanism and the right supporting mechanism are rotationally connected to the platform assembly. The lower supporting mechanism is rotationally connected to the bottom of the platform assembly, the upper supporting mechanism is fixed to the lower supporting mechanism, each supporting mechanism can stretch and retract in the axial direction, and then supporting of the platform assembly is achieved. According to the suspension rail platform with the support, a supporting platform, a rock drilling rig, an anchor rod drilling machine or a digging working arm and other working mechanisms can be assembled, the working environment as stable as the ground can be achieved, parallel operation of the suspension rail platform and roadway lower tunneling equipment is achieved, the stability of equipment operation on the platform is guaranteed, construction safety is guaranteed, and the construction efficiency is obviously improved.
