Description
One, technical field
The present invention relates to a kind of bonded structure of steel rail of the uninterrupted contact along a plane, more particularly, relate to the various vehicles that orbit, for example train, tram, urban light rail train etc. in the process of travelling, can be all the time along the bonded structure of steel rail of a plane linear uniform motion.
Two, background technology
The transverse joint that existing bonded structure of steel rail is kept somewhere between connected two one steel rails is fixed according to the swell value design of single rail maximum under the normal temperature state.The function of this connectivity transverse joint is that the swell value that track is formed by warm-up movement can be with the form in-fighting along its length of single rail, thereby the amplitude of guaranteeing track deformation is zero, this link technique defective the most intuitively then is, along the direction of speed, the excircle of wheel being in contact with one another between two one steel rails is interrupted.Under the effect that does not have other external force, when fastening bolt links together two one steel rails by inside and outside clamping plate, the interactional power equal and opposite in direction of clamping plate and rail, two ends are vertical mutually with the inclined-plane of rail contact both sides up and down with clamping plate for direction, connected two one steel rails and clamping plate longitudinally are in parastate, and structure is along laterally having possessed the spring function identical with the rail other parts.But, this phenomenon not as much as to say in the structure along horizontal interactional power, also in the vertical direction has satisfied the essential condition that makes its total maintenance inactive state, because structure with the interactional process of wheel in, the gravity that the load-bearing end of rail imposes on clamping plate straight down, and another one steel rail end to the holding power of clamping plate with interactional inclined-plane is vertical between the two, gravity points to two different directions respectively with holding power, therefore these two power is also non-vanishing with joint efforts, that is to say that two clamping plates of the prior art does not have the function of equivalent transmission gravity between two one steel rails in fact.So, when wheel during in the coupling part by two one steel rails, the reaction force that structure constitutes gravity, be that two of rail ends are unaided respectively in the different time in opposite directions in the structure, at one time in, two ends that are connected rail are along the size of the direction acting of gravity and inequality, perhaps more precisely, in the process of gravity acting, the last position of load-bearing end of rail and the first position of non-bearing end of rail be not on identical level height.
Above-mentioned phenomenon explanation, in this ancient design scheme, gravity and holding power, basic just not according to the equilibrium of forces principle, equal and opposite in direction, direction act on same the straight line on the contrary.Hence one can see that, tradition discontinuous bonded structure of steel rail existing technological deficiency is that not merely wheel and rail contacting in the longitudinal direction be interrupted, and, along the direction of speed, the contact of this discontinuity also can't maintain on the identical level height.Effect of impact moment that to be exactly wheel contact with another one steel rail end ladder in the process of motion forms.And the safety of this bump by many times to the speed of a motor vehicle, power consumption, noise, vibrations and train operation, stability, all many-sided negative effects that constitutes such as comfortableness are attributed to the discontinuity contact simply, obviously are wrong.
And above-mentioned non-equilibrium stressed design defect also is prevalent in " vertically uninterrupted contact bonded structure of steel rail " and other still adopts clamping plate to connect, in nearly all prior art.Therefore, only on the surface of structure, formed the supporting part that can uninterruptedly contact with wheel, and can't make load-bearing ingredients different in the structure at suffered gravity or be not subjected to always to be maintained at the same horizontal plane under the situation of gravity, any type of, be intended to address the aforementioned drawbacks and the effort of paying, all be futile.
Three, summary of the invention
Purpose of the present invention, exactly in order to solve above-mentioned discontinuity contact and the non-equilibrium two kinds of stressed design defect that prior art exists simultaneously, a kind of novelty is provided, the coefficient bonded structure of steel rail of multiple spot power, this syndeton in the vertical direction can be stressed with wheel balance, can contact incessantly along a plane all the time with wheel in the longitudinal direction, eliminate two kinds of factors that effect of impact forms, also just fundamentally eliminate the various drawbacks that form by above-mentioned defective simultaneously.
The objective of the invention is to reach: the travel bonded structure of steel rail of usefulness of a kind of rail vehicle by following technical proposal, by rail, inner splint, the securing member of external splint and various connection usefulness is formed, it is characterized in that, the middle part at above-mentioned rail two ends and above-mentioned two clamping plate inboard have in opposite directions formed the bossing of both wings side direction respectively and in order to hold the sideslip groove of above-mentioned bossing; And on above-mentioned interior (or outer) top of clamping plate and the same side at above-mentioned rail both ends, also formed the bossing of central load-bearing respectively and in order to hold above-mentioned bossing recess, thereby, formed both wings lateral protrusions part and the sideslip groove is stressed with wheel balance, the bossing of the end face of rail and clamping plate and wheel uninterruptedly contact along a plane all the time bonded structure of steel rail along the different directions of gravity and speed.

Five, the specific embodiment
See also Fig. 1, the improved rail that adopts in the label 1 expression first embodiment of the invention, the inner splint that the above-mentioned rail of connection that adopts in the label 2 expression first embodiment of the invention is used, the external splint that the above-mentioned rail of connection that adopts in the label 5 expression first embodiment of the invention is used, in addition, connect the securing member snap bolt 4 of usefulness in addition, spring pad 3 and hex nut 6, but these parts are all same as the prior art, do not change.What need further specify is, Fig. 1 reflected is the situation that on interior (or outside) clamping plate in structure the bossing of central load-bearing is set, forms recess on the same side at top, rail two ends, if bossing all is set on two clamping plates, and on two sides at rail both ends, all form recess, so, the planform of above-mentioned two clamping plates is then identical, does not also just have inside and outside having divided in application process.
As shown in figures 1 and 3, the middle part at above-mentioned rail 1 two ends has formed respectively along its length and can break away that groove cooperatively interacts with clamping plate, and length is L, and width is t, highly be the bossing of the both wings side direction of h; And the top at above-mentioned rail 1 two ends, also having formed length respectively on the same side that inner splint is installed is l, width is the recess of T, in order to hold the central load-bearing bossing of above-mentioned clamping plate.The planform in the cross section of above-mentioned rail both wings lateral protrusions part and two ends recess as shown in Figure 5.
As Fig. 1, Fig. 2 and shown in Figure 4, above-mentioned inner splint 2 and external splint 5 middle part in opposite directions are parallel to the length direction of former clamping plate inner groovy, and having formed width respectively is t, highly is h, and the inboard chute of connectivity is in order to hold the both wings lateral protrusions part of above-mentioned rail; And on the end face of above-mentioned inner splint 2, also having gone up and having formed length is B, and width is central load-bearing bossing T, that can cooperatively interact with above-mentioned rail two ends recess.The planform in the cross section of above-mentioned two clamping plate sideslip grooves and inner splint central authorities load-bearing bossing as shown in Figure 5.
Fig. 5 is the cross-sectional drawing of two one steel rail joining parts among first embodiment of bonded structure of steel rail of the present invention, the syntagmatic in the expression structure between each parts.As seen from Figure 5, when fastening bolt linked together two one steel rails by inside and outside clamping plate, the bossing of above-mentioned rail both wings side direction was contained in above-mentioned clamping plate with the opposite direction of level, in two sideslip grooves in opposite directions; The central load-bearing bossing of above-mentioned inner splint then is close to the recess at above-mentioned rail both ends, and the end face of its bossing flushes with the end face of rail.
As seen from Figure 1, though bonded structure of steel rail of the present invention is at connected two one steel rails, and between the bossing of the recess of rail and clamping plate, still leave and to make displacement energy that track forms by warm-up movement dilatation seams with the form in-fighting along its length of single rail, but, the transverse joint of connectivity has been eliminated in the tradition syndeton, and, form in the most effective scope of extruding or friction in wheel flanges and track, the bossing of inner splint has replaced that the intersegmental rail that has broken and the recess of rail, thereby wheel supported by the bossing of rail and clamping plate in advancing all the time.Though above-mentioned technical characterictic is identical with prior art, the purpose that reaches is also identical, but, owing to act on the size and Orientation difference of the power in the structure, effect and effect that above-mentioned identical technical characterictic can reach are completely different, and this difference has possessed substantial improvement, rather than conspicuous.
By Fig. 1 or Fig. 5 as can be known, in bonded structure of steel rail of the present invention, wheel imposes on its gravity, it is the holding power (or pulling force) that partly forms when two ends interact up and down by rail both wings lateral protrusions with clamping plate sideslip groove, transmit mutually between two one steel rails along the vertical direction of these two power, be with the substantial difference of prior art, in structure of the present invention, the direction of gravity and holding power (or pulling force) is always pointed to the object of being pressed or being supported perpendicular to seating surface, they are all on same straight line.Like this, no matter the particle of action of gravity is on the central load-bearing bossing of clamping plate, still act on the rail at these bossing two ends, the bossing of both wings side direction can both be at one time in sideslip groove by clamping plate, gravity is passed to equally the other parts of structure, and in the scope that the particle two ends equate, obtain the holding power of equivalent, thereby make real having possessed load-bearing and transmitted the function of gravity of clamping plate among the present invention along opposite direction.
By Fig. 1 or Fig. 5 also as can be known, only in the process that gravity is got involved, interactional relation just can take place with the sideslip groove of clamping plate in the both wings lateral protrusions of rail part in opposite directions, thereby interior at one time formation equivalent holding power, and, the wheel effect gives the gravity of structure big more, structure is also just big more to the reaction force that gravity constitutes, when the constant magnitude of gravity was constant, the size of reaction force was also invariable, and gravity fails, structure also disappears immediately to the reaction force that gravity constitutes, can determine thus, at any time, act on gravity on the optional position and holding power (or pulling force) in the structure, its size and Orientation all is constant, their equal and opposite in direction, direction is opposite, balances each other.Therefore, syndeton of the present invention is at suffered gravity or be not subjected under the situation of gravity, connected two one steel rails and inside and outside clamping plate still can move in the process of expanding with heat and contract with cold in the other direction, but in the vertical direction can only remain static, be that in the vertical direction does not have acceleration, thereby make wheel in the process of advancing, can be all the time be in contact with one another incessantly along supporting parts different in a horizontal plane and the structure.And structure middle clamp plate and rail remain unchanged along the size and Orientation of horizontal interactional power, with gravity interactional relation do not take place.Like this, interactional power is on level and vertical two different directions in the structure, satisfied the essential condition that makes ingredients different in the structure always keep inactive state simultaneously, fundamentally eliminate discontinuity contact and non-equilibrium stressed design defect in the prior art, reached the final purpose that the present invention will reach.
See also Fig. 6 to Fig. 8 below, these several figure have represented the second embodiment of the present invention.In this embodiment, except the structure of rail 1 ' and inner splint 2 ' and first embodiment different, the structure of all the other members all with embodiment 1 in identical, and play a part identical.
As Fig. 6 and shown in Figure 8, rail 1 ' among the embodiment 2 except form at the top at two ends recess with the bossing that holds inner splint 2 ', also on above-mentioned bossing, formed boss rank D, in the recess of above-mentioned rail both ends, formed the concave station rank C that holds and cooperatively interact with above-mentioned boss rank D, during connection, the bottom surface of above-mentioned boss rank D is pressed on the end face of above-mentioned concave station rank C.As shown in Figure 7 and Figure 8.
Among first embodiment in the present invention, the suffered wheel of clamping plate bossing imposes on its gravity, be directly passed to adjacent rail both wings lateral protrusions part by the sideslip groove, can be owing to still leave between two one steel rails for the expand with heat and contract with cold dilatation seams of usefulness of track, therefore, when wheel is pressed over the vertical direction of certain one steel rail end and clamping plate bossing, the size of the suffered gravity of two one steel rails in the structure, two one steel rails still exist faint difference to the size of the reaction force of gravity formation in other words.And in second embodiment of the invention, because the boss rank of clamping plate can be pressed on the end faces above-mentioned rail both ends, two concave station rank simultaneously, thereby eliminated the deficiency among the embodiment 1, like this, the acting in conjunction of multiple spot power makes gravity and the holding power in the structure can be in the absolute equilibrium state all the time, and has strengthened the abampere total head of structure load bearing stength to greatest extent.
In addition, the recess at top, rail two ends among the present invention can only be formed on the track inboard near wheel flanges, also can be formed on the inside and outside both sides of structure simultaneously, and the bossing of central load-bearing all is set on inside and outside two clamping plates, to adapt to different technical needs; All right middle part and two clamping plates inboard in opposite directions at above-mentioned rail two ends, form both wings lateral protrusions portion and the sideslip groove that cooperatively interacts respectively, any transformation then needn't be carried out in the top of rail and clamping plate, thereby form another kind of more simple, the steel syndeton of force balance discontinuous contact, and can receive and the essentially identical technique effect of above-mentioned two schemes.And, bonded structure of steel rail of the present invention also can be only with the form of structure itself separately as a kind of product (being the length that the total length of product only is slightly larger than clamping plate), still with fusing mode on straight track to another kind of prior art, be that modern seamless track (or claiming superlong steel rail) is transformed, like this, both can eliminate the lengthwise movement and in subrange, causing significantly of swell value that this track forms by warm-up movement, irregular track deformation is to the restriction and the influence of the speed of a motor vehicle and traffic safety formation, can maximally utilise existing rail facility again, avoid the waste of resource.
In addition, the size of Reference numeral reflection of the present invention should be selected according to the model of rail and clamping plate, and the length 2L of rail both wings lateral protrusions part should be greater than the length of clamping plate, to strengthen the elastic strength at rail both ends itself; And the height of above-mentioned clamping plate sideslip groove also should equal or be slightly larger than the height of rail both wings lateral protrusions part, so that install and use and reduce between the two friction factor.To rail commonly used and the clamping plate that are complementary with it, general length L can be in 400～500 millimeters scope, and width t can be in 15～20 millimeters scope, and height h can be in 40～60 millimeters scope; And the length B of the length l of top, rail two ends recess and clamping plate central authorities load-bearing bossing also should cooperatively interact, and B should be more than or equal to 2l, so that reserve the gap between two one steel rails.For rail commonly used and the clamping plate that are complementary with it, general length l is in 60～80 millimeters scope, and B is in 120～160 millimeters scope, and width T is in 15～30 millimeters scope.In addition, rail two ends concave station rank C in the second embodiment of the present invention and the height h ' of clamping plate boss rank D can be in 20～25 millimeters scopes, and width t ' is in 5～10 millimeters scope.
In sum, because bonded structure of steel rail of the present invention is ensureing that fully former design scheme middle clamp plate and rail are interactional, under all constant situation of the size and Orientation of power, also according to the equilibrium of forces principle, with gravity and holding power equal and opposite in direction, direction acts on same the straight line on the contrary, thereby make that different load-bearing ingredients is in contact with one another incessantly along a plane and wheel all the time in the structure, and the displacement that track is formed by warm-up movement, form in-fighting along its length that still can single rail, the restriction and the influence that the speed of a motor vehicle and traffic safety are constituted from the structure of track or deformation itself have been eliminated, and real the reaching or realized all the time of the traveling process that finally makes rail vehicle along the perfect condition of a smooth plane linear uniform motion, therefore it is faster train operation to be got, safer, more steadily comfortable, energy-conserving and environment-protective.Simultaneously; because the present invention has only improved the structure of end of rail and clamping plate; original roadbed, sleeper, electrified facility; even the heavy rail that has even just come into operation on straight track recent years can utilize in transformation again; so; help energy conservation and protection environment, house of correction needs small investment, can save substantial contribution.
