Abstract
The invention discloses a composite metal pipe and honeycomb core anticreeper with external honeycomb core. A metal pipe component and a honeycomb core component are simultaneously arranged, namely the honeycomb core component is arranged on the metal pipe component in a sleeving manner, so that under the premise that the energy absorbing capability of the anticreeper is not reduced, the diameter varying amount of the metal pipe is effectively reduced by reasonably distributing the energy absorbing amount needed to bear by energy absorbing structures; therefore, the generating probability of phenomena, such as deformation and cracking, caused by a too large diameter varying amount of the metal pipe, is reduced; the defect that a structure with a single honeycomb core is poor in capability of bearing lateral loads is overcome; the reliability of equipment is improved, and the service life of the equipment is prolonged; the anticreeper is guaranteed to effectively complete the task of energy absorption; the life and property of passengers are protected.
Description
Technical field
The present invention relates to technical field of rail traffic, the metal tube that in particular a kind of honeycomb core is external-honeycomb core combined type anti-creeper.
Background technology
Along with developing rapidly of track traffic, train running speed is more and more faster, the operation speed per hour of present high speed train is more than 300km/h, high speed train is once the collision case such as to knock into the back will bring a large amount of personal casualty and property damage, while raising ACTIVE CONTROL reliability, passive security protection also more and more comes into one's own.Anti-creeper is that widespread use in field of track traffic a kind of has both and prevent from train from riding climbing the mechanical device with buffering energy-absorbing function, usually be made up of anti-creep structure and endergonic structure two parts, traditional anti-creeper uses as honeycomb core compression or metal tube reducing type anti-creeper are generally single form, once there is honeycomb core cracking, to topple or the fault such as metal tube flexing easily causes anti-creeper thoroughly to lose efficacy, thus losing the situation of energy-absorbing protective capacities, reliability cannot ensure.
The anti-creeper of single metal tube reducing type anti-creeper has following shortcoming: 1, reducing amount is large, reducing difficulty, in order to fully absorb the huge energy in train knockout process, metal pipe type anti-creeper requires harsh to version and manufactured materials, when metal tube material and radial dimension (comprise caliber and wall thickness, usually determined by installing space) timing, metal tube reducing type anti-creeper wants to improve energy absorption ability, usually only have and increase length and increase reducing amount two kinds of methods, and the length dimension of anti-creeper is subject to the restriction that train body two ends can utilize space usually, thus can only select to increase reducing amount, the such as existing metal tube reducing type anti-creeper used ON TRAINS, when metal tube is of a size of Φ 170 × 10(external diameter × wall thickness) time, reducing amount needs to reach more than 5mm could meet energy-absorbing requirement, huge reducing power often causes breaking of metal tube or flange, reducing is caused to be difficult to carry out, 2, because Conversion of Energy form is single, the kurtosis of initial energy-absorbing stage impact load is large, and steady energy-absorbing stage load fluctuation is large, and protected device vibration is large.
Single honeycomb core type anti-creeper has following shortcoming: 1, anti-bending strength is poor; In order to alleviate anti-creeper quality, the thin-walled foil closed assembly that honeycomb core self is often below 0.2mm for thickness forms, inside has a large amount of vestibule, side direction load-carrying capacity will much smaller than axis, under the lateral forces of clashing into initial time easily because of occur overflexing, fracture or topple and lost efficacy, the cell type anti-creeper of such as certain specification, under the lateral loading effect of 10KN, the cellular material in anti-creeper will tear phenomenon.2, the kurtosis of energy-absorbing starting stage impact load is large, and steady energy-absorbing stage load fluctuation is large.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art; the metal tube that the object of the present invention is to provide a kind of honeycomb core external-honeycomb core combined type anti-creeper; solve the reducing difficulty of single metal tube reducing type anti-creeper in prior art; the resistance to bending of single honeycomb core type anti-creeper is poor and kurtosis both because of initial energy-absorbing stage impact load is large; steady energy-absorbing stage load fluctuation is large, causes protected device to vibrate large defect.
