Abstract
A self-lubricating switch slide plate comprises slide plates provided with limit iron seats. The limit iron seats on each slide plate are disposed on the slide plate in bilateral symmetry. A lubricating component is fixed on the top of each slide plate between the limit iron seats. The self-lubricating switch slide plate is placed on switches for lines to be switched, and rails are placed on the self-lubricating switch slide plate. Before line switching, the switch is pulled, and the rail is adjusted to the required position easily by the aid of lubricant in cavities on the slide plates with the tightly attached lubricating components below the rail. The self-lubricating switch slide plate guarantees running safety and meets the service requirement for switch setting for heavy load materials. A lubricating coating is generated, so that increased setting resistance of the switch caused by rusting of the surface of the slide plate is solved effectively. The self-lubricating switch slide plate is applicable to the field of switches for railways for transporting heavy load materials such as coal and sand.
Description
Technical field
The utility model relates to a kind of railway track facility, relates in particular to a kind of railway track track switch that is applied to transport the heavily loaded materials such as coal and sandstone and uses the turnout baseplate with self-lubricating function.
Background technology
Track switch is the vitals that on railway track, circuit switched is used, and its normal operation is the basic guarantee of whole traffic safety.And manage to reduce the conversion resistance force of track switch, the operational reliability that improves track switch is the target that domestic and international railway interests makes great efforts always.While changing due to track switch, the frictional force between point tongue and turnout baseplate is an important component part of conversion power, and manages to reduce this frictional force, is to reduce one of effective ways of changing power.
And lower method generally adopted of technology now arranged at present, be to be coated with oil lubrication between tongue and turnout baseplate, reduce the conversion resistance force of tongue, yet this lubricating system has all weak points, as Climatic issues, lubricated not comprehensively, need a large amount of manpower and materials etc., in order to overcome between tongue and slide plate the weak point that is coated with oil lubrication method, in recent decades the railway interests of a lot of countries all in development without oiling, reliability is high, performance is good turnout baseplate.
And the self-lubricating turnout baseplate of external development roughly can be divided into two types:
1. the first type is to replace traditional sliding friction with rolling friction, and the sliding bed platform on turnout baseplate is designed to the special construction with ball, makes tongue complete conversion with the rolling form;
2. the second type is to adopt the material with self-lubricating property to make the sliding bed of a track switch platform, then welding, to spray, to inlay, the method such as bonding is fixed on turnout baseplate, makes the self-lubricating turnout baseplate without oiling.
Yet the track switch of above-mentioned these two kinds of methods and existing painting lubrication oil formula all is not suitable for the railway track of the heavily loaded materials such as transportation coal and sandstone, and its reason is as follows:
The freight volume of coal and sandstone is very large, and the oiling track switch of using at present is easy to the stone of sticky glutinous coal and sandstone the inside, materials such as quartz sand for braking, causes the track switch conversion bad.And ballast is clipped between tongue and stock rail and also can makes track switch not change to put in place, easily cause train to slide down, in addition, along with adapting to heavily loaded needs, the point tongue own wt can be heavier, make switch convert resistance excessive, the sliding bed of the contacted track switch of common turnout baseplate and tongue face platform adopts general steel plate or cast iron to make, its coefficient of kinetic friction can change according to the difference of slide plate surface lubrication state between 0.2～0.3, just adopt at last rolling friction to replace the way of traditional sliding friction also can't meet the demand of the track switch conversion under fully loaded transportation condition, if and the transportation area rainy day is more, especially when plum rain season, the phenomenon that turnout baseplate gets rusty happens occasionally.Same, just adopt at last " material with self-lubricating property is made the sliding bed of a track switch platform; again welding, to spray, to inlay, the method such as bonding is fixed on turnout baseplate; make the self-lubricating turnout baseplate without oiling " this way is also not all right, because the slide plate surface can produce corrosion, friction factor can further increase, result also can cause switch convert resistance to increase, conversion resistance force increases can extend track switch conversion time, the haulage vehicle travelled on respective lines is caused to potential danger, and because of conversion resistance force, to increase the fault cause of common occurrence.
In addition, if use the old-fashioned mode of lubrication oil to carry out track switch lubricating, not only to drop into a large amount of manpower and materials, and can cause that the excessive meeting of turnout baseplate oil surface causes the dirty of surface, brings larger environment pollution to scene.
In sum, but the turnout baseplate that now needs a kind of novel self-lubricating, can solve wasting time and energy and with serious pollution defect of old-fashioned painting oil lubrication, also can solve the demand of the track switch conversion of the heavily loaded material of reply, and can also tackle the slide plate surface and can produce the problem that switch convert resistance that corrosion causes increases.
The utility model content
In order to address the above problem, but the utility model provides a kind of turnout baseplate of self-lubricating, turnout baseplate structure by redesign, can effectively carry out self-lubricating, can also tackle extra-duty heavy loading object truck when preventing the corrosion problem, bearing capacity that can also the balance turnout baseplate when reducing switch convert resistance, concrete structure of the present utility model is as described below:
But a kind of turnout baseplate of self-lubricating, comprise the slide plate that is provided with the limiting iron seat, it is characterized in that:
Limiting iron seat on described slide plate is being arranged on slide plate of bilateral symmetry formula, on the plate face of the slide plate between the limiting iron seat, is fixedly installed lubrication assembly.
