The concept in the described direction such as horizontal, vertical, longitudinal, is all benchmark with rail herein, and respectively with the horizontal, vertical of rail and longitudinally corresponding, wherein said rail longitudinal direction, is the bearing of trend of rail; Rail is vertical, vertical namely at the bottom of Rail; Laterally, namely rail web midship section is vertical for rail.

The comprehensive lateral stiffness of Track Anti beat spacing device refers to that it is when rail head is subject to the horizontal force along rail transverse direction in the present invention, and horizontal force and the ratio of the lateral displacement at rail head place, be also called for short the lateral stiffness of Track Anti beat spacing device.The lateral displacement of rail head comprises the transverse translation of rail and rail around the deflection of rail longitudinal direction, containing the contribution of fastener deflection stiffness, therefore as without refering in particular to, no longer in addition deflection stiffness being discussed.The elastic deformation of rail own is ignored in addition.

On current subway and light rail market, the most frequently used high resiliency fastener has Cologne egg, pioneer's fastener.The vertical Static stiffness of Cologne egg within the scope of 0 ~ 15kN is 8-14kN/mm, and the rail head lateral displacement of single fastener under vertical 40kN and horizontal 20kN acts on simultaneously is 2.6 ~ 4mm, and calculating comprehensive lateral stiffness is 5-7kN/mm; The vertical Static stiffness 5kN/mm of pioneer's fastener, vertical dynamic stiffness is 6kN/mm, and lateral stiffness is 9 ~ 12kN/mm, and calculating the rail head lateral displacement of single fastener under vertical 40kN and horizontal 20kN load act on simultaneously is 1.6 ~ 2.2mm.These two kinds of fasteners wheel track in the use procedure of China's city underground there occurs recurrent inordinate wear, and it is its main cause that inventor analyzes lateral stiffness too low.

The vertical Static stiffness scope of the general fastener of China's subway solid concrete roabed is 30 ~ 40kN/mm, and lateral static stiffness scope is 20 ~ 60kN/mm, inordinate wear does not occur.Therefore, if lateral stiffness is greater than 15kN/mm, under horizontal 20kN effect, rail head lateral shift is less than 1.3mm, substantially can meet the instructions for use of subway and light rail.

If the lateral stiffness of fastener is not enough and can not change fastener or improve the lateral stiffness of fastener, the pull back device that the present invention can be taked to advise increases the lateral stiffness of fastener.Although the tensile strength of current rail distance rod is enough, bending rigidity wretched insufficiency is the object that can not reach bending resistance.Calculated example is as follows: the rail distance rod diameter of standard is 32mm at present, even if join a pull bar for 60 rail for the every contacting piece of every bar circuit, suppose that the anti-beat ability of 2/3 is provided by pull bar, the spacing inside circuit two one steel rail between the flange of rail is approximately 1350mm, and rail head horizontal force height gets 161mm according to standard, size is 14kN, this moment of flexure will make pull bar bend, and rail head deflects, and the lateral deflection of rail head is approximately 22mm, far beyond safety value, cause derailing.When being in fact used as rail distance rod, only every 3 ~ 5 contacting pieces join a pull bar.That is, the bending resistance that the density of current rail distance rod and thickness provide is nowhere near, at least low 67 times from demand!

If adopt bending resistance binding beam, following standard should be met: during with fastener synergy, under adjacent two fasteners longitudinal middle rail head of rail bears the condition of the lateral force of 20KN, the lateral displacement of rail head is less than 1.3mm, or the comprehensive lateral stiffness of rail head is not less than 15kN/mm.If how much more scarce the lateral stiffness of fastener is than above-mentioned value, bending resistance binding beam just should fill how many.Such as: if the lateral stiffness of Cologne egg is 5kN/mm, the lateral stiffness that bending resistance binding beam converts rail head should be just 10kN/mm, namely under the effect of 20kN proof force, when fastener does not provide rigidity, because the lateral shift that bending resistance binding beam bends the rail head caused should be 2mm.In order to save material, should hollow beam be made, just (82cm can be not less than as long as do not reduce along the second moment of area I that rail is vertical ⁴).Long 1800mm and specification is the rectangular steel pipe of 80 × 40 × 5, weight is 15.5kg, if adopt the H profile steel of equal length 80 × 80 × 3.8 × 5.2, the every root of weight is still about 15.5kg, but obtainable second moment of area is larger such as!

The existing gauge connecting rod quality of diameter 32mm, long 1800mm is about 11.3kg, far can not meet the instructions for use of bending resistance, although same length and the rectangular steel pipe weight that specification is 80 × 40 × 5 slightly increase, but owing to selecting bending resistance section bar in bending resistance, bending resistant section moment of inertia improves greatly, can meet the requirement of track lateral stiffness.As can be seen here, existing gauge connecting rod is not considered bending resistance completely and is improved the demand of system lateral stiffness in design and selection process, only consider the needs of tension, therefore simple spacing function can only be realized, with in Track Anti beat spacing device of the present invention to the difference requiring essence of bending resistance binding beam, the final object realized is also incomplete same.In Track Anti beat spacing device of the present invention, bending resistance binding beam needs the instructions for use simultaneously meeting tension and bending resistance, therefore the present invention can not only realize the basic function of spacing, raising system lateral stiffness can also be played, alleviate or overcome that horizontal sliding between rail lateral stiffness deficiency causes under External Force Acting wheel track is comparatively large thus horizontal rollings of the train caused strengthens, comfort level reduces, the problems such as quickening of wearing and tearing, and there is the defects such as extraordinary wave mill under given conditions, be conducive to the application life of improving rail, improve safety and the comfortableness of driving simultaneously.

Track Anti beat spacing device of the present invention, by arranging bending resistance binding beam and clamp assemblies, clamp assemblies is utilized to coordinate with steel rail web or rail wing plate, bending moment is born with the bending resistance binding beam with stronger bending rigidity, while raising rail lateral stiffness, effectively can offset the external world and disturb the bending moment that masterpiece produces the flange of rail for rail head of rail phase, what therefore can effectively control in the rail course of work is shimmy, it is more outstanding that it prevents rail from crossing the advantage of quick-wearing, and effect is more obvious.In addition, because Track Anti beat spacing device of the present invention can significantly increase fastener vibrating isolation system mass of vibration by arranging the technological means such as counterweight or spacing support member, therefore it effectively reduces the intrinsic frequency of rail fastening vibrating isolation system under can be implemented in and not changing the flexible prerequisite of fastener, reduce rail vibration amplitude, improve the vibration isolating effect of fastener vibrating isolation system, effectively can improve comfortableness during train travel, especially after adopting sound absorption material or sound absorption construction in counterweight or spacing support member, the present invention can also realize good anti-acoustic capability, it goes for existing various fastener system.In sum, Track Anti beat spacing device of the present invention has simple and compact for structure, and orbit space utilization rate is high, vibration and noise reducing superior performance, economical and practical, and the plurality of advantages such as applicability is strong, market application foreground is very wide.

Embodiment one

As shown in Figure 1, ballastless bed for short sleeper, short sleeper 2 is fixed on railway roadbed 100, and rail 1 is erected at above short sleeper 2.Existing spacing connecting rod comprises the connecting rod 98 be arranged between two parallel one steel rails 1, and connecting rod 98 two ends arrange bayonet socket 99, and bayonet socket 99 is locked respectively at the flange of rail place of two one steel rails 1.Connecting rod 98 in existing spacing connecting rod is substantially for tension design, and less consideration moment of flexure, so existing spacing connecting rod tension is strong, bending resistance is weak, therefore this spacing connecting rod can ensure the gauge of the flange of rail, but can not limit the vibration displacement that rail head produces due to moment of flexure.Bayonet socket due to this spacing bracket is the flange of rail place being locked at rail bottom, and rail has certain height, when the railhead part of rail is stressed, larger bending moment can be produced relative to the flange of rail, therefore rail still can produce shimmy,, even there is ripple mill phenomenon in this shimmy wearing and tearing exacerbating rail further.In summary, although existing spacing connecting rod can well control gauge, it does not possess the ability alleviating rail abrasion substantially, fully cannot meet instructions for use.

As Fig. 2, Track Anti beat spacing device of the present invention shown in Fig. 3, be made up of bending resistance binding beam 4 and clamp assemblies, under bending resistance binding beam 4 is positioned at rail, and between adjacent fastener 6, clamp assemblies arranges two groups, the position of corresponding rail is arranged on the two ends of bending resistance binding beam 4 respectively, the two ends of bending resistance binding beam 4 are connected with two parallel one steel rails 1 respectively by clamp assemblies, often organize clamp assemblies and comprise two blocks of mutual corresponding anti-balance cocks 5, two blocks of anti-balance cocks 5 with group are clamped in the both side surface of same rail 1 web of the rail respectively, all anti-balance cocks 5 are all weldingly fixed on bending resistance binding beam 4.Wherein, bending resistance binding beam 4 is made up of channel-section steel, and anti-balance cock 5 is made up of cast steel material.Anti-balance cock 5 is identical with steel rail web surface profile shape with the surface profile of steel rail web contact site, and with web of the rail surfaces mate.

During use, Track Anti beat spacing device of the present invention is set on rail 1 in advance, then by utilizing fastener 6 to be fixed on short sleeper 2 by rail 1, forms overall track structure together with railway roadbed 100.Because the lateral stiffness of Track Anti beat spacing device of the present invention is comparatively large, effectively can limit transverse vibrational displacement during rail work, prevent rail spacing from changing excessive, therefore spacing effect is very reliable.The bending resistance binding beam 4 made due to Track Anti beat spacing device middle slot steel of the present invention again has very high bending rigidity, anti-balance cock 5 is clamped in the web of the rail both sides of rail 1, its structural strength is larger, stressed more reasonable, can bear the moment that the stressed phase of rail head produces the flange of rail, prevent rail 1 from deflecting, alleviate rail 1 work in shimmy, and not fragile, the comfortableness of train driving is better, its performance preventing rail 1 from occurring to wear and tear is more superior, and application life is also longer.

Track Anti beat spacing device of the present invention not only has all functions of common spacing connecting rod, can also bear larger yaw moment simultaneously, solves the difficult problem crossing quick-wearing that rail beat causes, is conducive to the application life of significantly improving rail.In addition, compared with existing common spacing connecting rod, Track Anti beat spacing device longer service life of the present invention, maintaining cost is lower, and cost performance is higher, and market application foreground is very wide.

It is pointed out that the concept in the described direction such as horizontal, vertical, longitudinal herein, is all benchmark with rail, and respectively with the horizontal, vertical of rail and longitudinally corresponding, wherein said rail longitudinal direction, is the bearing of trend of rail; Rail is vertical, vertical namely at the bottom of Rail; Laterally, namely rail web midship section is vertical for rail.All like this later in all embodiments, no longer repeat specification.In addition, except the channel-section steel mentioned, described bending resistance binding beam can also adopt the solid profiles such as sheet metal, metal bar, H profile steel or i iron, or adopts hollow metal pipe material, the round steel pipe that such as local, two ends flattens, can also utilize the techniques such as welding to make box-shaped or other structures.Certainly, glass fiber reinforced plastic, concrete or engineering plastics also can be utilized to make bending resistance binding beam, as long as enough along the bending rigidity of bending resistance binding beam axis, and meet the requirement in space, instructions for use of the present invention can be met.

As shown in Figure 4, directly to contact with clamp assemblies and bending resistance binding beam to prevent rail and produce noise and unexpected wearing and tearing, between anti-balance cock 5 and the web of the rail of rail 1, set up cushion pad 7, cushion pad 41 under rail is set between rail 1 and bending resistance binding beam 4.Under cushion pad 7 and rail, cushion pad 41 is made by elastomeric material, is specially elastomeric material and makes.Under cushion pad 7 and rail, cushion pad 41 can effective filter high-frequency stress wave, damped vibration energy, and therefore, the vibration and noise reducing performance of having set up the Track Anti beat spacing device of the present invention of cushion pad 41 under cushion pad and rail is better.It is to be noted, described elastomeric material is except the ordinary elasticity materials such as rubber, elastic polyurethane or resilient foam material, elastomeric material described in the present invention also comprises visco-elastic damping material and composite elastic material, the cushion that such as high-damping polyurethane is made, the rubber pad etc. with fabric enhancement Layer.Under certain formation cushion pad 7 and rail, the elastomeric material of cushion pad 41 also should have certain abrasion resistance.

It should be noted that in addition, Track Anti beat spacing device of the present invention all can be arranged in space between each sleeper, also can arrange compartment of terrain in the space according to actual needs between adjacent sleeper, certainly can also only arrange at the local segment of track circuit, in the application can according to the quantity of actual demand choice for use of track circuit and the density of layout.In general, determine that the principle of Track Anti beat spacing device density of setting of the present invention or quantity is, when rail head of rail bears the lateral force of 20kN, should ensure that the lateral displacement of rail head of rail is no more than 1.3mm.Space between described adjacent sleeper is identical with the space meaning between adjacent fastener.This feature is equally applicable to other technologies scheme of the present invention, illustrates in the lump, no longer repeated description at this.

Emphasize a bit, bending resistance binding beam in the present invention, the requirement of tension and bending resistance will be taken into account when design and selection simultaneously, following standard should be met: during with fastener synergy, under adjacent two fasteners longitudinal middle rail head of rail bears the condition of the lateral force of 20KN, the lateral displacement of rail head is less than 1.3mm, or the comprehensive lateral stiffness of rail head is at least not less than 15kN/mm.If how much more scarce the lateral stiffness of fastener is than above-mentioned value, bending resistance binding beam just should fill how many.For Cologne eggs fastener, comprehensive lateral stiffness to meet rail head reaches 15kN/mm, if the lateral stiffness contribution of Cologne egg is 5kN/mm, the lateral stiffness that bending resistance binding beam converts rail head just should be at least 10kN/mm, namely under the effect of 20kN proof force, when fastener does not provide rigidity, because the lateral shift that bending resistance binding beam bends the rail head caused should be not more than 2mm.Through calculating, the bending resistance binding beam adopted should ensure that the second moment of area I along rail is vertical is not less than 820000mm ⁴.Pioneer's fastener lateral stiffness is larger, with the use of the second moment of area I of bending resistance binding beam certainly can be slightly smaller.If wish that lateral stiffness is larger, also can be more greatly.Above-mentioned bending resistance binding beam design and select in principle and points for attention illustrate in the lump at this, no longer repeated description in Examples hereinafter.
