The invention belongs to the technical field of vibration sensors of gas turbines, and particularly relates to a vibration sensor support for a gas turbine. The support balance weight is added to change the gravity center position, the inherent frequency of the support is reduced, and it is avoided that vibration value collection is interfered due to the fact that resonance is generated due to the fact that the inherent frequency is the same as the driving frequency of a gas turbine case. Two bolt holes are formed in a lug base plate and a fastening metal plate, the fastening metal plate is installed on the other side of a casing flange, fastening bolts are used for connecting the fastening metal plate with the bolt holes in the upper end of the lug base plate, the vibration sensor support is tensioned, and axial swing vibration of the support is effectively reduced. A cooling flow channel in the support is designed, cooling gas is introduced from a support connector and cools a vibration sensor probe through
