The invention relates to the field of construction equipment vibration reduction design, in particular to a construction equipment rubber vibration isolation device. A plurality of rubber supports are fixedly arranged on a reinforced concrete main beam or a concrete mound arranged on the reinforced concrete main beam, the reinforced concrete main beam has sufficient strength and rigidity, a vibration device is fixedly erected on the rubber supports, the heights of the rubber supports are coincident, and the compression deformation amounts of the rubber supports are coincident. The rubber supports are small in occupied space and are easily installed on roofs and in floors; the rubber supports made of different materials and provided with different models can be selected according to parameters, physical properties, locating environments and the like of the vibration device; the construction equipment rubber vibration isolation device is suitable for vibration isolation of devices with high operation frequencies. The invention further relates to an installation method of the construction equipment rubber vibration isolation device, and the construction equipment rubber vibration isolation device on the floor face can be conveniently and rapidly installed.
