The invention provides a compression resistance cap in a dangerous chemical transport vehicle energy-absorbing device. The compression resistance cap comprises a cone-shaped cap body which is of a hollow structure, all surfaces of the cap body are each provided with a protective layer, and the end face of the end, with a larger external diameter, of the cap body is a plane. The protective layers are zinc-plating layers or bead weld nickel alloy layers, the taper value of the cap body is 75+/-5 degrees, the wall thickness of the cap body ranges from 3 mm to 4.5 mm, and the cap body is made of Q235 steel or Q236 steel. The inner wall of the cap body is provided with a reinforcing structure. According to the compression resistance cap in the dangerous chemical transport vehicle energy-absorbing device, the structural design is reasonable, and the assembled energy-absorbing device is good in overall energy-absorbing effect; the cone-shaped cap body is adopted, so that compared with the structure shaped like a rectangle and the like, the structural stability is good, and the compression requirement for an energy-absorbing tube during a collision can be better met. The protective layers are the zinc-plating layers or the bead weld nickel alloy layers, rusting of the cap body is effectively prevented, the friction coefficient of the surface of the cap body is increased, and therefore it is guaranteed that effective compression is conducted on the energy-absorbing tube in the collision process of the compression resistance cap.
