The guide mechanism 4 is installed between the mounting plate 2 and the contact plate 3, and guides the movement of the contact plate 3.
The number of the guide mechanisms 4 is two, and the two guide mechanisms 4 are staggered in the horizontal direction and the vertical direction.
The anti-climbing energy absorption devices are mounted at the end parts of the bodies of the railway vehicles, and when the vehicles collide, as shown in figures 2 to 5, the anti-climbing teeth of the anti-climbing energy absorption devices on the two bodies are in mutual contact.
The anti-climbing energy absorption devices on two collided vehicle bodies are set, one is a first anti-climbing energy absorption device A, and the other is a second anti-climbing energy absorption device B. Because the two guide mechanisms on the anti-creep energy-absorbing device are respectively arranged on the left and the right and staggered in the vertical direction, the two guide mechanisms on the same side are staggered in the vertical direction when the two anti-creep energy-absorbing devices are opposite.
Therefore, as shown in fig. 2, after the two anti-climbing and energy-absorbing devices contact the anti-climbing teeth, the contact plate 3 of the first anti-climbing and energy-absorbing device a retreats to the mounting plate 2, the energy-absorbing component 1 collapses and deforms, and the guide mechanism 4 of the second anti-climbing and energy-absorbing device B can intrude into the first anti-climbing and energy-absorbing device a.

In order to realize the guiding of the contact plate 3, the guiding mechanism 4 includes a guiding seat 41 and a guiding member 42.
The guide member 42 is slidably installed in a guide groove 43 provided in the guide holder 41, the guide holder 41 is coupled to the mounting plate 2, and the guide member 42 is coupled to the contact plate 3.
The guide 42 is a guide bar or a guide plate.
As shown in fig. 1, when the guide member 42 is a guide rod, one end of the guide rod extends out of the guide seat 41 and is fixedly connected to the contact plate 3 by the bolt 6, and a protrusion 44 provided at the other end of the guide rod abuts against a step 45 provided on an inner wall of the guide groove 43, in order to clamp and fix the energy absorbing member 1.
The contact plate 3 is pressed at one end of the energy-absorbing component 1, the energy-absorbing component 1 is propped against the mounting plate 2, the bolt 6 is gradually screwed, and the guide rod approaches the contact plate 3 and gradually extends out of the guide groove 43. The step 45 on the guide groove 43 limits the guide rod through the protrusion 44, preventing the guide rod from further extending, so that the fixedly mounted guide seat 41 pulls the contact plate 3 through the guide rod, and the contact plate 3 firmly presses the energy-absorbing component 1 on the mounting plate 2.
When the guide member 42 is a guide plate, which is not shown in the drawings, to clamp and fix the energy absorbing member 1, the guide plate is fixedly connected to the contact plate 3 as a single body and abuts against a step 45 provided on an inner wall of the guide groove 43.

As shown in fig. 1, when the guiding means 4 are located outside the energy absorbing part 1, two guiding means 4 are located on two opposite corners of the mounting plate 2; when the guiding means 4 are located inside the energy absorbing part 1, the two guiding means 4 are located at two diagonal positions of the cavity of the energy absorbing part 1.
As shown in fig. 1, to further increase the rigidity of the energy absorption element 1 between the contact plate 3 and the mounting plate 2, both guide means 4 bear against the side wall of the energy absorption element 1 on the respective side.
When the guide mechanisms 4 are positioned outside the energy-absorbing part 1, the guide mechanisms 4 are attached to the outer side wall of the energy-absorbing part 1, so that the two guide mechanisms 4 clamp the energy-absorbing part 1 to a certain extent, the energy-absorbing part 1 is firmer, and meanwhile, the two guide mechanisms 4 limit the energy-absorbing part 1 in the left and right directions, so that the collapse direction of the energy-absorbing part 1 is more accurate, and the force value stability is higher; when the guide mechanism 4 is positioned in the energy-absorbing component, the guide mechanism 4 is attached to the inner side wall of the energy-absorbing component 1, the illustration drawings are not shown, the energy-absorbing component 1 is supported, meanwhile, the energy-absorbing component 1 can be limited in the left and right directions, and the accuracy of the crumpling direction is improved.
