The specific embodiment
As shown in Figure 1, a kind of urban rail transit vehicles conquassation formula energy-absorbing anti-creeper, comprise body, body is formed by connecting by energy absorption device and anti-creep device, fixing onboard by 2 welding of anti-creep termination 1 and anti-creep pipe or other anti-creep device that is formed by fixedly connecting by the car body adapter plate 4 that is enclosed within on the anti-creep pipe 2, connecting panel 5 is combined into one 2 balance blocks 6 of homonymy, the sliding guide mechanism of forming anti-creeper with the balance backplate 8 of other two sides be arranged on anti-creep pipe 2 around, be connected with between balance backplate 8 and the anti-creep termination 1 and adjust pull bar 9, the collision energy-absorbing anti-creeper is smoothly moved in the backplate groove of car body, adjust pull bar 9 and can pass through adjustable bolt pretension energy-absorbing anti-creeper, make bearing cap shim and car body crossbeam closely connected, also can adjust the squareness of energy-absorbing anti-creeper and car body, the other end of anti-creep pipe 2 is connected by the energy absorbing tube 3 usefulness bolt of flange 11 and energy absorption device, the other end of flange 11 is energy-absorbing connecting panels 10, and the other end of energy absorbing tube 3 is closely connected by adjusting energy-absorbing pad 7 and car body crossbeam; Described anti-creep termination 1 is the flute profile aluminum casting, the vertical force when bearing collision; Described anti-creep pipe 2 is square, is to be welded by 2 U templates; The material of described energy absorbing tube 3 is composite materials such as aluminum alloy, carbon steel and foamed aluminium; Described energy absorbing tube 3 be shaped as multiple shapes such as thin-walled hexagon honeycomb, square and circle, these thin-wall metals can have multiple arrangement mode, absorb requirement according to different-energy, can select the thin-wall metal of different structure form and thickness, fore-end at power-absorbing has guiding groove, to impel distortion, can be allowed to condition to have in the collision process and stablize the distortion that continues from appointed part.Energy-absorbing plate 12 is made up of energy-absorbing dividing plate 13 energy-absorbing gussets 14 respectively among Fig. 2, Fig. 3.The principle of work of energy absorption device: the thin-wall metal that adopts rule is as energy absorbing element, the thin-wall metal of rule can produce when being impacted stablely continue, orderly plastic deformation absorbs energy.
The beneficial effects of the utility model: energy-absorbing anti-creeper is made up of crushing type energy-absorbing device and anti-creep device two parts. Crushing type is to utilize pipe fitting to be subjected to axial compressive force conquassation distortion to absorb bump kinetic energy. This energy absorption device has the conquassation stabilization; crushing force is steady; simple in structure, be easy to the advantages such as replacing; vehicle is when bumping; bump kinetic energy can be absorbed in an orderly manner and converts to plastic deformation ability by energy absorption device; when train produces collision with 20～25km/h speed, can effectively protect passenger life safety, and guarantee that body construction does not produce plastic deformation. The anti-creep structure is the rectangular tube structure, by engaging tooth foremost, bears certain vertical force, and when preventing car body collision, a train head is cut the phenomenon of climbing up in another train, the possibility that the reduction accident takes place.
The simple replacement of those skilled in the art and replacing all are within this patent protection domain in this area.
