A guide-type anti-climbing energy-absorbing device based on hydraulic shearing includes an energy-absorbing tube, an anti-climbing portion, a first connecting portion, a plurality of partition plates, and two guide plates. The anti-climbing portion and the first connecting portion are respectively provided at two ends of the energy-absorbing tube. The partition plates are sequentially arranged inside the energy-absorbing tube along an axial direction to divide the interior of the energy-absorbing tube into a plurality of first energy-absorbing cavities, each filled with a first honeycomb body. The two guide plates are symmetrically arranged in the energy-absorbing tube along a vertical direction of the energy-absorbing tube. Each guide plate is arranged obliquely and includes a connecting end connected to the anti-climbing portion and a free end passing through the partition plates in sequence to extend outside the first connecting portion.
