Abstract
The utility model discloses a guard seat, the structure of which is a long strip shape. An end head block wall is arranged on two ends. The section plane of the long strip comprises a first long straight border, a second long straight border, a first short straight border, a second short straight border, a third short straight border and a first circular arc, wherein, the upper end of the first long straight border is intersected with the front end of the first short straight border. The back end of the first short straight border is intersected with one end of the first circular arc. The other end of the first circular arc is intersected with the upper end of the second short straight border. The lower end of the second short straight border is intersected with the back end of the third short straight border. The front end of the third short straight border is intersected with the back end of the second long straight border. The first long straight border is not intersected with the second long straight border. The lower end of the first long straight border and the front end of the second long straight border are respectively intersected with two ends of a curve line, furthermore, the lowest point of the curve line is lower than the intersection point between the prolonging lines of the first long straight border and the third short straight border. The change of the shape of the guard seat increases the stress area, thereby obviously prolonging the life span of the guard seat.
Description
Affiliated technical field
The utility model belongs to the railway field of components, particularly relates to the apron block field of use between concrete sleeper and gauge apron.
Background technology
In recent years, along with developing rapidly of national economy, also very urgent as the development of the aortic railway traffic cause of economy.In order to satisfy the needs of national economic development and living standards of the people, on the one hand, the speed of passenger train operation significantly improves, on the other hand, goods train also improves the traction quality constantly, therefore, line construction is bearing from the dual-pressure of speed-raising passenger vehicle with the weightening finish lorry, and line construction and relevant spare and accessory parts all need further to improve to strengthen.II type, IIIA type sleeper are down with apron block such as Fig. 1, Fig. 2, shown in Figure 3 at present.Apron block 1 structure is a strip, and its two ends respectively are provided with termination shelves wall 11, and the cross section of strip is surrounded by first long straight flange 12, second long straight flange 13, first short straight flange 14, the second short straight flange 15, circular arc 16.Angle between the first long straight flange 12 and the second long straight flange 13 is greater than 90.Apron block 1 is set level with sleeper shoulder block 8 closely connected, and gauge apron 5 rear ends 51 must fall in the circular arc 16 of apron block 1, front end 52 keeps closely connected with the flange of rail, and spring 4 passes bolt 6 and withholds on gauge apron 5, by nut 2 lockings that are provided with pad 3.High speed, high-quality train operation needs can not have been adapted to apron block under this II type, the IIIA type sleeper, mainly be because: when a, high-speed overload, when make a concerted effort increasing of lateral force that concrete sleeper shoulder block place is subjected to and gravity and shoulder block place lifting surface area are constant, be subjected to bigger pressure, thereby the concrete sleeper shoulder block often breaks; B, for a long time, a lot of producers use material not improve along with field requirement and improve, cause apron block resistance to compression, impact strength not enough, the constant compression permanent deformation is bigger, particularly tractive force and centrifugal force are all bigger on sharp radius curve, often have by the phenomenon of conquassation, change, keep in repair the waste great amount of manpower and material resources.
Summary of the invention
The utility model is intended to provide a kind of security performance good apron block at above-mentioned the deficiencies in the prior art part.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of apron block, structure is a strip, its two ends respectively are provided with termination shelves wall, the cross section of strip comprises the first long straight flange, the second long straight flange, the first short straight flange, the second short straight flange, the 3rd short straight flange, first circular arc, the front end of the upper end of the first long straight flange and the first short straight flange intersects, the rear end of the first short straight flange and an end of first circular arc intersect, intersect the upper end of the other end of first circular arc and the second short straight flange, intersect the rear end of the lower end of the second short straight flange and the 3rd short straight flange, intersect the front end of the 3rd short straight flange and the rear end of the second long straight flange, the first long straight flange and the second long straight flange are non-intersect, the front end of the lower end of the first long straight flange and the second long straight flange intersects with the two ends of a curve respectively, and the minimum point of curve is lower than the joining of the first long straight flange extended line and the 3rd short straight flange extended line.
Be linked with the 4th short straight flange between the front end of the upper end of the first long straight flange described in the utility model and the first short straight flange, its extended line meets at the second long straight flange.
Curve described in the utility model is the 5th short straight flange.
The front end of the rear end of the second long straight flange described in the utility model and the 3rd short straight flange is linked with second circular arc.
The described in the utility model the 3rd short straight flange is a three-arc.
It is described in the utility model that to intersect or connect all be level and smooth intersecting or level and smooth the connection.
Advantage of the present utility model is: curve is set, and when train operation, the lateral force that concrete sleeper shoulder block place is subjected to can be decomposed into the power of all directions, and power is little and be not easy to produce stress and concentrate, and obviously prolong application life; The minimum point of curve is lower than the joining of the first long straight flange extended line and the 3rd short straight flange extended line, the component of the lateral force that the pairing face of apron block first straight flange produces when only being subjected to train operation, pairing of the second long straight flange, the 3rd pairing of short straight flange, the pairing face of curve have all decomposed lateral force, increased its lifting surface area, pressure suffered on each face is little, pressure is little, apron block obviously prolongs application life, and also little to the pressure at concrete sleeper shoulder block place, the possibility of bursting apart in the shoulder block place is also little; Be provided with the same component of having shared lateral force of the 4th short straight flange, increased lifting surface area; Be provided with second circular arc component of having shared lateral force too, increased lifting surface area; Be provided with the three-arc component of having shared lateral force too, increased lifting surface area; The minimum point of curve is lower than the joining of the first long straight flange extended line and the 3rd short straight flange extended line, and apron block can be located voluntarily; The 3rd short straight flange, the 4th short straight flange, first circular arc, second circular arc, three-arc are set all to be helped apron block and locatees voluntarily; Described to intersect or connect all be level and smooth intersecting or level and smooth the connection, can not cause stress to concentrate, and required precision is too not high, low cost of manufacture; The model of apron block can be provided with different sizes as required; This apron block can be applied in the many abominable places of circuit, natural conditions of mountain area small radius, can also use the location that increases in speed increase in vehicle, weight; Improve the job stability of whole rail structure, guaranteed traffic safety; Has tangible social effect.
