Abstract
The rolling stock top of slowing down is installed on the rail, and the wheel of process is carried out braking deceleration.It is the dynamic equilibrium cone valve of feature that the present invention has with the water conservancy diversion platform, the guide cylinder spiracle adopts the internal channel form, be provided with lining between the cylinder body sliding surface, adjustment mechanism of buffer stop hydraulic efficiency gear and guide cylinder carriage captive joint can be prevented from dash take off And through simple just adjust can the conversion hydraulic efficiency gear and guide cylinder between relative height, make this device can be common to rail inboard or outside installation.
Description
The present invention is come by British patent's 1328086 disclosed those class car retardation top development.This deceleration top is fixed on the rail, and when the car speed through the top of slowing down was higher than specified value, the top of slowing down made car retardation to wheel brake activation merit.
In known deceleration roof construction, fluid pressure dynamic characteristics instability in the pressure valve modulated pressure device causing the braking force instability of deceleration top to wheel, causes the decline of specified braking work, or when car speed is higher moment the braking force superelevation, jeopardize traffic safety.Known in addition deceleration top design height immobilizes, can not be general in the rail medial and lateral.Sliding oil cylinder contacts with the guide cylinder direct friction, influences other part wear-out life.Do not have between piston rod and the guide cylinder and captive joint, hydraulic efficiency gear might be deviate from guide cylinder.Spiracle is located at lower end, the guide cylinder outside, contamination and plugging easily.
At the above-mentioned defective of prior art, task of the present invention is: design a kind of stable hydraulic braking characteristic that has, reliable operation, the life-span is longer, clean attractive in appearance, rail medial and lateral general-duty car retardation top.
The foregoing invention task is solved by the technical characterictic of claim 1-7.
The present invention increases the water conservancy diversion platform outside the taper valve face circumference of known pressure valve, constitute the feature of dynamic equilibrium cone valve, thereby improves the dynamic hydraulic characteristic of the fluid of the taper valve face of flowing through when valve is opened, and makes the top of slowing down obtain good pressure regulation braking effect.Owing to adopt adjustment mechanism of buffer stop, prevented that not only hydraulic efficiency gear accident in the guide cylinder from deviating from, and, adapted to the needs that install and use two kinds of positions, rail medial and lateral with this through the simple relative height that just can change hydraulic efficiency gear of adjusting.The feature of claim 5 provides protection to the cleaning of guide cylinder spiracle.Claim 6 and 7 feature have been improved the sliding capability of oil cylinder, have reduced the frictional loss of cylinder body.
In conjunction with the accompanying drawings invention is described further with the following examples:
Fig. 1: the front view on the top of slowing down.
Fig. 2: the view of dynamic balance valve.
Fig. 3: the cutaway view of guide cylinder.
Fig. 4: the adjustment mechanism of buffer stop when being used for the rail inboard.
Fig. 5: the adjustment mechanism of buffer stop when being used for the rail outside.
(4) are dynamic balance valves among the figure, and its head taper valve face (see figure 2) and valve seat 5 are closely connected, and valve seat (5) endoporus leads to oil cylinder epicoele (A).The extendible portion of valve (4) conical suface is connected with water conservancy diversion platform (6) planar annular, forms the plane of action of dynamic balance valve (4) jointly.Water conservancy diversion platform (6) is perpendicular to the axis of valve (4), and the same valve seat of this platform (6) (5) lower surface forms a gap when valve (4) is closed, is communicated with hoel of piston crown (13).When wheel with greater than predetermined speed during through sliding oil cylinder (1) top, the high pressure oil of oil cylinder epicoele (A) is pushed dynamic balance valve (4) downwards open, valve seat endoporus and hoel of piston crown (13) are connected in space between conical suface and the same valve seat of water conservancy diversion platform (6) (5) bottom surface, (A) chamber fluid flows to (B) chamber, produces braking work thereby consume the wheel energy.Water conservancy diversion platform (6) produces the flow force compensation effect to pressure oil simultaneously, improves the dynamic characteristics that hydraulic pressure is adjusted, and makes the top of slowing down produce the stable braking work that continues and acts on wheel.
Fig. 4 and Fig. 5 show a kind of embodiment of adjustment mechanism of buffer stop.The red seat (10) that ends that is positioned at guide cylinder (2) bottom is connected with piston rod (7) by pivot pin (12).Open a hole in guide cylinder (2) sidewall relevant position, insert and end towards adjusting pin (11), this adjusting pin end is positioned at the only top on red seat (10) peripheral annular plane, plays position-limiting action to ending red seat (10).Be thus connected fixingly between deceleration top hydraulic efficiency gear and the guide cylinder carriage, after the top of slowing down is to the wheel decelerates work done, avoided hydraulic efficiency gear to recoil in the guide cylinder (2) or other are improperly deviate from, guaranteed device security work.
Only being positioned at, ending towards the end of adjusting pin (11) of red seat (10) planar annular top has one section half-cylindrical breach (14) (see figure 4).Make breach (14) upwards when rotating adjusting pin, rely on the face of cylinder of adjusting pin spacing, can be fixed on lower position ending red seat to ending red seat (10).In contrast, make breach (14) downward when rotating adjusting pin, (see figure 5) then relies on the breach plane (14) of adjusting pin spacing to ending red seat (10), ends red seat and can be fixed on higher position.By rotating adjusting pin (11) And at adjusting disk (15) that ends red seat (10) upper and lower surface filling some and adjustment backing plate (16), can be according to the different needs that is installed on the rail inboard or the outside, at any time adjust Gao Du And is fixed up between deceleration top hydraulic efficiency gear and the guide cylinder carriage, having realized slowing down withstands on rail medial and lateral general-duty purpose.
As shown in Figure 3, on the inwall of guide cylinder (2), have air channel (17).On the casing wall between guide cylinder installation bracket (3) and two bolt blocks of rail bonded assembly, have spiracle (8), be communicated with air channel (17).When hydraulic efficiency gear came and went slip, the gas of guide cylinder (2) bottom passed in and out thus.Arrange the position of spiracle (8) like this, help passing in and out the cleaning of air, be difficult for being stopped up, also help beautifying of outward appearance by dirt.
By the lining (9) that sliding oil cylinder (1) outside face is provided with between the slidingsurface that guide cylinder (2) inside face is formed or twice are made by composite material, thereby in sliding oil cylinder (1) and guide cylinder (2) slide relative process, replace oil cylinder and the friction of leading between the casing wall with the cliding friction between oil cylinder and the lining, thereby reduced the main wearing and tearing And of part in addition and simplified the processing technology of part slidingsurface in addition relatively, to bringing benefit in cost-cutting and the service life that prolongs this device.Select for use soft abrasion resistant composite material to make lining simultaneously and also improved the sliding capability of oil cylinder (1), improved the sensitivity of this device work.
