Abstract
The invention relates to a subway train anti-climbing energy absorber, and belongs to the technical field of a railway vehicle collision protective device. The subway train anti-climbing energy absorber comprises an installing anti-climbing tooth and an installing base, wherein the installing base is arranged on an underframe end beam. The installing base is connected with the anti-climbing tooth via energy absorbing pipes and guide rods, induced holes are evenly distributed in the energy absorbing pipes, guide holes allowing the guide rods to penetrate through are left in the installing base, and guide pipes are installed in the guide holes. One ends of the guide rods are fixedly connected to the anti-climbing tooth, and the other ends of the guide rods penetrate through the guide pipes installed on the installing base. The guide rods and the guide pipes are used for guiding, and then the guiding performance is good. Compared with a traditional carbon steel anti-climbing device, a lightweight design is conducted on the anti-climbing energy absorbing structure, the subway train anti-climbing energy absorber is installed and welded by aluminum profiles, therefore, the weight is light, production and machining are simple, different anti-climbing crushing force values can be acquired by adjusting relevant parameters of the profiles, and therefore good adaptability is achieved for the design.
Description
Technical field
The present invention relates to a kind of subway train anti-creep energy absorber, belong to guideway vehicle collision protection equipment technology field.
Background technology
Along with track traffic continuous advancement in technology and development, the collision safety problem has become a focus of guideway vehicle design study as the important component part in the modern vehicle design; When crashing; special-purpose energy absorption device by being attached to a car front end or friction, fracture, the flexing of a car car body vulnerable part structure, collapse mode such as crumple with huge bump kinetic energy dissipation, and protect the complete of passenger life safety and railway car primary body structure to greatest extent.The railcar anti-creeper adopts carbon steel structure more at present, though the guiding energy-absorbing is better, weight is heavier, cost is higher, if anti-creeper adopts non-carbon steel structure weight lighter, but guidance quality is relatively poor.
Find by retrieval; the patent No. provides a kind of used for rail vehicle anti-creep energy absorption device for 201220561307.5 Chinese patent; effectively absorb Impact energy by the energy-absorbing body by the structure structure of outside jacket plates; play protection car body and personnel's effect; but there is complex structure in this device; improved manufacturing cost by baroque energy-absorbing material, simultaneously for reach design strength also be select for use the heavier I-beam section of weight and and steel plate, increased the overall weight of device.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the shortcoming of prior art, and a kind of subway train anti-creep energy absorber is provided, and has that good steering capability, weight are light, easy for installation, the very big cost of having saved of processing; The power of while anti-creeper is worth adjustable controlled, satisfies the requirement of different vehicle anti-creep greatly.
In order to solve above technical matters, the invention provides subway train anti-creep energy absorber, comprise anti-climbing tooth and the mount pad on the underframe end carriage are installed, between described mount pad and anti-climbing tooth, be connected with guide rod by energy absorbing tube, be evenly distributed with on the described energy absorbing tube and induce the hole, leave the guide hole that passes for described guide rod on the described mount pad, and at described guide hole conduit is installed; Described guide rod one end is fixedly connected on the described anti-climbing tooth, and the other end passes the conduit that is installed on the described mount pad.
Further technical scheme of the present invention, aforesaid subway train anti-creep energy absorber, described energy absorbing tube is square tube, described inducing on the rib that the hole is evenly distributed on described square tube, can make energy absorbing tube in collision process by designing requirement steady-state deformation longitudinally.
Aforesaid subway train anti-creep energy absorber, at least be furnished with four energy absorbing tubes between described mount pad and the anti-climbing tooth, described guide rod is installed between described four energy absorbing tubes, energy absorbing tube and guide rod form a kinematic pair freely, play guide function by guide rod, energy absorbing tube absorbs energy, when anti-climbing tooth moves near conduit, the energy absorbing tube distortion finishes, and climbs the car tendency this moment and produces, and guide rod can produce a vertical application force to conduit, but guide rod, conduit and underframe front end girder construction intensity are enough big, because the engagement of anti-climbing tooth can't have been climbed car body, finally play the effect of anti-creep simultaneously.
Further, aforesaid subway train anti-creep energy absorber, described conduit and described mount pad junction are connected and fixed by strengthening gusset.
The invention has the beneficial effects as follows: the present invention utilizes guide rod and conduit to lead, and steering capability is good; With respect to traditional carbon steel anti-creeper, this anti-creep endergonic structure has carried out light-weight design, adopts the aluminium section bar assembly welding to form, weight is lighter, production and processing is simple, can obtain different anti-creep conquassation power values by the correlation parameter of adjusting section bar, and design is had comformability preferably.

The specific embodiment
Embodiment 1
A kind of subway train anti-creep energy absorber that present embodiment provides, structure such as Fig. 1 are to shown in Figure 2, comprise anti-climbing tooth 1 and the mount pad on underframe end carriage 23 are installed, be connected with two guide rods 5 by six roots of sensation energy-absorbing square tube 4 between mount pad 3 and anti-climbing tooth 1, two guide rods 5 are installed between the six roots of sensation energy-absorbing square tube 4; Be evenly distributed with on four ribs of energy-absorbing square tube 4 and induce hole 6, leave the guide hole that passes for guide rod 5 on the mount pad 3, and at guide hole conduit 7 is installed, conduit 7 is fixed by reinforced rib 8 plates with the mount pad junction; Guide rod one end is fixedly connected on the anti-climbing tooth, and the other end passes the conduit that is installed on the mount pad.
The anti-climbing tooth of present embodiment is extruded aluminium section, mainly plays engagement; The energy-absorbing square tube is made up of the hollow extrudate, according to pressing the feedback distortion to absorb energy, can realize the not demand of syn-collision interfacial force easily by adjusting section material section and wall thickness simultaneously; Mount pad is the aluminium sheet structure; Guide rod is extruded aluminium section, and the guiding energy absorbing tube longitudinally is out of shape when being used for collision, avoids energy absorbing tube unstability in deformation process; Conduit is extruded aluminium section.Anti-climbing tooth, energy-absorbing square tube, mount pad and guide rod lump together through soldering group, carry out bolt by the bolt hole on the mount pad and underframe end carriage and are connected, and be convenient to whole device and change fast when crashing; Conduit is welded on the underframe end carriage.When being installed, the energy-absorbing anti-creep device only needs whole device propulsion bulb is got final product, and convenient and swift.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
