Abstract
The utility model discloses a lever pressure head mechanism for a vehicle hook buffer of a loading and unloading press machine of a railway vehicle, which is arranged on a machine body of a loading and unloading press machine. The utility model is composed of a hydraulic oil cylinder, a lever matched with the hydraulic oil cylinder, a priority valve rod for fixing the level, a pressure head matched with the pressure point of a heavy arm of the lever, pressure plates on both sides of the pressure head, and two front iron stopping baffle plates, wherein the pressure plates on both sides of the pressure head are fixedly connected with a back plate of the pressure head into one body; the two iron stopping baffle plates are arranged on both sides of the front end of a hook sleeve of a vehicle hook buffer, and block both sides and the lower end part of the hook sleeve of the buffer of the vehicle hook. The lever pressure head mechanism changes a lever mechanism with two plates. The lever pressure head mechanism has advantages that the lever pressure head mechanism is firm and can not be damaged, and the pressure plates on both sides of the pressure head are comparatively thin, and can be easily inserted in a gap; moreover, the vertical surfaces contact a sub plate completely, the sliding move does not exist, the born pressure is large and the safety is high.
Description
Technical field
The lever pressure heads mechanism of the railway vehicle coupler energy disperser loading and unloading press that the utility model uses when relating to a kind of rolling stock department maintenance vehicle.
Background technology
A kind of machine that railway vehicle coupler energy disperser loading and unloading press often uses when being rolling stock department maintenance vehicle, it is generally by the traveling chassis, fuselage placed on it, Ke Zhuandong lifting mechanism not, hydraulic power unit, electric system, left/right movement devices etc. are partly formed, and its core is the leverage of coupler draft gear, leverage of the prior art is by hydraulic ram, two levers, the fulcrum pin axle that two levers are through is together formed, the back slave plate of the weighing arm pressure point compression coupler draft gear during use on the lever, thereby compression buffer, the shortcoming of its existence is: because the thickness of two levers is restricted, surpass thickness and then insert not advance in the slit and can't work, cause the weighing arm pressure point of lever often to damage; Lever is when the back slave plate of compression buffer, and the weighing arm pressure point is to be that rotate in the center of circle with the fulcrum pin axle, so the weighing arm pressure point is a sliding process with contacting of back slave plate.Tens tons gravity pressure but also is to slide on the weighing arm pressure point, so the weighing arm pressure point often damages, or bursts apart and flies out, and is very dangerous, causes whole two levers to be scrapped, and can't work.
Summary of the invention
The technical problems to be solved in the utility model provides the lever pressure heads mechanism of a kind of long service life, the non-damageable railway vehicle coupler energy disperser loading and unloading of lever press.
The technical scheme in the invention for solving the above technical problem is: the lever pressure heads mechanism of railway vehicle coupler energy disperser loading and unloading press, it is located on the fuselage of loading and unloading press, the lever that it matches by hydraulic ram, with hydraulic ram, the fulcrum pin axle of truck dead lever, the pressure head, pressure head two side guides and two front iron retaining baffles that match with the gravity arm of lever pressure point constitute, the back plate of pressure head two side guides and pressure head fixes as one, two front iron retaining baffles are located at the both sides of hook case of car coupler buffer front end, and block the both sides and the bottom of hook case of car coupler buffer.
The technological advance that the utility model is obtained is: lever pressure heads mechanism of the present utility model is thick strong, not fragile, and the pressure heads mechanism biside plate can insert very smoothly and exerts pressure in the slit, in the whole process of exerting pressure two side guides of pressure head with by the slave plate of compression buffer, it is the whole contact of facade, do not have sliding phenomenon, contact surface is big, and is firm not fragile.This lever pressure heads mechanism has changed the leverage of two plates in the past, and its advantage is firm and do not damage; Two side guides of pressure head and thicker back slave plate have been welded into " ㄈ " type, and two side guides are thinner, be easy to insert in the slit, and facade are that integral body contacts with slave plate, and fricton-tight to bear pressure big, safe and reliable.

The specific embodiment
Shown in Fig. 1-6, the lever pressure heads mechanism of railway vehicle coupler energy disperser loading and unloading press, it is located on the fuselage of loading and unloading press, the lever that it matches by hydraulic ram, with hydraulic ram, the fulcrum pin axle of truck dead lever, the pressure head, pressure head two side guides and two front iron retaining baffles that match with the gravity arm of lever pressure point constitute, the back plate of pressure head two side guides and pressure head fixes as one, two front iron retaining baffles are located at the both sides of hook case of car coupler buffer front end, and block the both sides and the bottom of hook case of car coupler buffer.Like this, when the lever pressure heads mechanism was exerted pressure to coupler draft gear, two facades of two side guides of pressure head were two facades and slave plate plane contact with contacting of slave plate of back, there is not sliding phenomenon, and pressure head can be moved in chute by slide shaft, and this new construction is firm, and is not fragile.Its principle of work is as follows: when needs unload the coupler draft gear of changing vehicle, with railway vehicle coupler energy disperser loading and unloading press, the electronic bottom of walking to coupler draft gear, fuselage is risen by lifting mechanism, but left-right rotation, by a left side, move right and align, and with in pressure heads mechanism two side guides insertion coupler draft gear and the vehicle towed beam, coupler draft gear and hitch rhampotheca are located in lever pressure head and front apron and end between the iron, start press, oil cylinder promotes lever through fulcrum pin axle, the weighing arm pressure point is pressed to pressure head, and two side guides of pressure head are pressed to slave plate behind the hitch, and pressure head can be with slide shaft together to front slide, because two are ended the rhampotheca that iron baffle plate and buting iron have blocked whole hitch, cause energy disperser to be compressed, at this moment coupler draft gear just can fall in vehicle towed beam easily, finishes the purpose that unloads coupler draft gear.When loading onto coupler draft gear, in contrast, after earlier whole coupler draft gear being fitted together, winch in the middle of the position of putting into the lever pressure heads mechanism, the loading and unloading press that carries coupler draft gear is walked to the draw beam bottom of vehicle.Start press through oil cylinder, piston rod, lever, fulcrum, weighing arm pressure point compression pressure head, two side guides of pressure head are pressed to the back slave plate, cause whole energy disperser to be compressed.Rise fuselage and whole lever pressure heads mechanism and align, and with pack into the draw beam inside of vehicle of complete coupler draft gear.Alleviate oil cylinder, the spring in the energy disperser unclamps, and back slave plate, preceding slave plate have been stuck within the draw beam.Lever pressure heads mechanism and fuselage fall, and the coupler draft gear press is left lower vehicle.Finished the work of unloading and loading onto of coupler draft gear.
