The invention discloses an intelligent electromechanical heating device for disassembling a cleat insulator. The device comprises rail walking wheels, two electric heating plates, an electric controlbox and a water tank. A U-shaped supporting plate is arranged on the rail walking wheels, the rail walking wheels are connected with the U-shaped supporting plate through a rotation shaft, and the water tank is arranged on the upper end face of the U-shaped supporting plate; a support and a fixing block are further arranged on the U-shaped supporting plate, the control box is fixed to the support,and a screw is arranged on the fixing block; a bearing is fixedly installed at one end of the screw, the bearings are fixed to vertical plates, and the screw penetrates through the fixing block; a thread hole corresponding to the screw is formed in the fixing block, the lower ends of the vertical plates are fixedly connected with the electric heating plates, and the two electric heating plates are arranged on the two sides edges of the U-shaped supporting plate respectively. According to the device, in limited time of a maintenance site, an ineffective steel rail insulation cementation connector is quickly disassembled, cleaned and assembled, the efficiency is improved, the material and labor cost is reduced, and the device is more reasonable and safer.
