Abstract
The utility model relates to a deformation unit for an electric locomotive which consists of an upper support plate, an endergonic steel tube, a bush and a lower support plate, wherein, the upper support plate is a T-shaped support plate, is arranged on the upper end inside the endergonic steel tube and fixed through a welding mode; the bush is arranged on the lower end inside the endergonic steel tube and extended into a locating hole of the lower support plate, namely, the bush, an inner hole of the endergonic steel tube and the locating hole of the lower support plate are in connection of interference fit; a deformation unit device is arranged on a coupler tank on a high power locomotive. The key function of the deformation unit device is that: when the locomotive makes an emergent brake or has an accident, the deformation unit device can absorb massive energy of impact or collision, and can effectively prevent important components of the locomotive such as a coupler, a brake beam, an underframe, etc. from being damaged caused by the impact or the collision.
Description
Technical field
The utility model relates to a kind of use for electric locomotive deformation unit.
Background technology
What China used the deformation unit device the earliest is on the subway city rail vehicle of import; but what adopt is expanding deformation unit device, impacts or the important spare part of collision energy protection subway city rail vehicle and the vibrations of buffering vehicle by the dilatating and deformable absorption of expansion steel pipe.But locomotive carry out emergency braking or situation about meeting accident under the important spare part of locomotive is sustained damage.
Summary of the invention
This uses later-model purpose to be to overcome above-mentioned deficiency, and a kind of high strength, high-ductility, employing axisymmetric buckling mode of texturing use for electric locomotive deformation unit are provided.
The technical solution of the utility model is: a kind of use for electric locomotive deformation unit, deformation unit is by upper backup pad, the energy-absorbing steel pipe, lining and lower supporting plate four parts are formed, its upper backup pad is a T shape stay bearing plate, fix on upper backup pad places in the energy-absorbing steel pipe and by welding manner, lining places the interior lower end of energy-absorbing steel pipe and extends the lower supporting plate knock hole, be that lining is that interference fit is connected with energy-absorbing steel tube inner hole and lower supporting plate knock hole, then carry out spot welding in the bottom of energy-absorbing steel pipe and the binding site on lower supporting plate plane, the energy-absorbing steel pipe connects with the mode of upper backup pad by welding, the upper deformation district that should guarantee the energy-absorbing steel pipe when welding can not produce overheated or distortion, in order to avoid the mechanical characteristics of energy-absorbing steel pipe is affected because of welding; Carry out under emergency braking or the something unexpected happened at locomotive; impact that is subjected to when the locomotive coupler place or collision energy surpass under the ceiling capacity situation that coupler draft gear can bear the energy-absorbing steel pipe of deformation unit to begin the axisymmetric buckling distortion and absorbs bigger impact energy, but the important spare part on the actv. protection locomotive car body.
The radical function of deformation unit device is under impact of rolling stock hypervelocity or accident condition, produces action to absorb big energy, reaches rolling stock is implemented the unexpected purpose of protecting.This deformation unit is a disposable product, produces should change immediately after action is out of shape; Capacity can reach several times, ten several times and even higher of locomotive buffer capacity, has very high capacity, to adapt to hypervelocity and accident conditions; Safety during for the guarantee routine, the deformation unit device only bears pressure, does not bear pulling force.
Hitch case on high-power locomotive is equipped with the deformation unit device; its key role is to work as locomotive under the situation of carrying out emergency braking or meeting accident; can absorb a large amount of impacts or collision energy, actv. protects locomotive important spare part such as hitch, brake beam, underframe etc. because of impacting or collision does not sustain damage.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is a plan structure scheme drawing of the present utility model;
Among the figure: 1-upper backup pad, 2-energy-absorbing copper pipe, 3-lining, 4-lower supporting plate.
The specific embodiment
Referring to Fig. 1, a kind of use for electric locomotive deformation unit, deformation unit is made up of upper backup pad 1, energy-absorbing steel pipe 2, lining 3 and lower supporting plate 4 four parts, its upper backup pad 1 is a T shape stay bearing plate, on upper backup pad 1 places in the energy-absorbing steel pipe 2, end is fixed by welding manner, lining 3 places energy-absorbing steel pipe 2 interior lower ends and extends lower supporting plate 4 knock holees, be that lining 3 is that interference fit is connected with energy-absorbing steel pipe 2 endoporus and lower supporting plate 4 knock holees, and carry out spot welding at energy-absorbing steel pipe 2 with the joint portion on lower supporting plate 4 planes and fix.
