Abstract
The invention discloses a slave plate structure for a railway good train coupler buffering device, which comprises a slave plate body and an abrasion plate, wherein the slave plate body is arranged in a coupler tail frame of the coupler buffering device; and the abrasion plate is arranged on one side of the slave plate body, and a main abrasion surface of the abrasion plate is contacted with the coupler tail frame. Because the abrasion coefficient of the abrasion plate is lower, abrasion is only generated on the abrasion plate, and the coupler tail frame has no abrasion basically. Therefore, the condition that the coupler tail frame needs to be welded due to transfinite abrasion cannot occur, and the problem of cracks due to improper welding of the couple tail frame is solved. When the abrasion of the abrasion plate exceeds the limit, only the abrasion plate needs to be replaced, and both the slave plate body and the coupler tail frame can be continuously used so as to save overhaul cost.
Description
Technical field
The present invention relates to lorry coupler buffering device, be specifically related to a kind of be used for lorry coupler buffering device from plate structure.
Background technology
Coupler buffering device is the vitals of railway vehicle, mainly is made up of hitch, hook tail frame, draft key, slave plate, energy disperser.In the vehicle operating process, the tractive force between vehicle is delivered to car body by hitch, draft key, hook tail frame, energy disperser, slave plate successively.Wherein, hook tail frame is the frame-type part of slave plate, energy disperser being installed and being born vehicle towed power and impulsive force, and the quality of its mode of operation is directly connected to safety of railway transportation.
But the supporting slave plate of 13 (13A, 13B) type hook tail frame of China's lorry dress usefulness adopts the Forging Technology manufacturing at present, has the bigger problem of abrasion between slave plate and the hook tail frame, particularly:
In vehicle operating, because the uncertainty of operating condition can make slave plate and hook tail frame produce relative friction force in the contact site.The slave plate that dress uses on the existing vehicle all is a forged steel pieces, can produce the friction of steel to steel between slave plate and the hook tail frame, is prone to cause the abrasion of slave plate and hook tail frame and surpasses limit value.When the abrasion of slave plate and hook tail frame are transfinited, need carry out repair welding to hook tail frame; After hook tail frame repair welding is handled, if repair welding improper meeting causing repair welding crackle.This is prone to cause fracture by fatigue in the utilization of hook tail frame, and causes train separation accident.In addition, in car inspection and maintenance, need to the part wear and tear serious slave plate, hook tail frame is changed, cost is than higher from economic angle.
For guaranteeing railway speed-raising truck, heavily stressed further developing, guarantee safety of railway transportation, must solve this type of accessory crack problem.
Summary of the invention
In view of this, the present invention provide a kind of be used for lorry coupler buffering device from plate structure, the repair welding crackle and the fatigue life that can solve after the hook tail frame abrasion are reduced the fracture accident that causes, also can reduce the cost of overhaul simultaneously.
For solving above technical matters, provided by the invention be used for lorry coupler buffering device from plate structure, comprising:, be arranged in the hook tail frame of coupler buffering device from plate body; Wearing plate is installed in a said side from plate body, and its main wearing surface can contact with said hook tail frame; Also comprise mount pad, be fixed on said from plate body; Said wearing plate is installed on the said mount pad.
Preferably, said mount pad is connected through screw between the plate body with said.
Preferably, said mount pad is provided with T-shape boss longitudinally, and said wearing plate is provided with T-shape groove longitudinally; Through cooperating of said T-shape boss and said T-shape groove, said wearing plate is installed on the said mount pad.
Preferably, said mount pad and said wearing plate are provided with dowel hole, are used for the installing and locating pin, prevent that said wearing plate from vertically moving.
Preferably, be respectively arranged with guiding surface between two of said wearing plate vertical sides and the said main wearing surface.
Preferably, said wearing plate is provided with the abrasion platform with the side that said hook tail frame contacts; The contact surface of said abrasion platform and said hook tail frame forms said main wearing surface.
Preferably, the friction coefficient of said wearing plate is 0.14～0.20.
Preferably, said wearing plate is that oil-containing nylon is processed.
Compared with prior art, the present invention provide lorry coupler buffering device from plate structure, increase wearing plate from plate body; Thus, the repair welding crackle and the fatigue life that solve after hook tail frame wears and tears are reduced the fracture accident that causes, reduce the cost of overhaul simultaneously.Particularly:
On the one hand, the wearing plate of oil-containing nylon material or other non-metallic materials has the low characteristics of friction coefficient, can effectively reduce or eliminate the abrasion of slave plate to hook tail frame.Abrasion only are created in wearing plate, and hook tail frame does not have abrasion basically, and hook tail frame can not occur transfinites because of abrasion and need the situation of repair welding, and this has also just eliminated crackle and repair welding position fatigue reliability reduction problem that hook tail frame occurs because of repair welding is improper.
On the other hand, wearing plate has advantages such as cost is low, replacing is convenient, can reduce the cost of overhaul effectively.Abrasion only occur in wearing plate, when the wearing plate abrasion are transfinited, only need to change wearing plate, and all can continue to use from plate body, hook tail frame; This had both practiced thrift accessory, had reduced the maintenance cost of labor again.
