The invention relates to the technical field of coal mine shaft bottom roadway detection, in particular to a roadway shape measuring device. The forward servo motor drives the detection assembly to move towards the positive direction of the z-axis, the rolling wheel tightly presses the rough surface of the roadway, the telescopic arm assembly and the swing arm assembly swing in a combined mode, every time the telescopic arm assembly swings to a new angle position theta, the farthest edge of the rolling wheel tightly presses a new corresponding point of the rough surface of the roadway, and the telescopic arm assembly stretches out and draws back to a new position. The encoder is driven to rotate to a new angle position psi, and the system calculates the distance r between the corresponding point of the rough surface of the roadway and the axial lead of the roadway; the coordinates of the detection points on the rough surface of the roadway are (r, theta, z), the system continuously collects and stores the coo
