Abstract
The utility model relates to a new railway switch sleeper, mainly comprising concrete switch sleepers (1), steel frogs (2) and rails (3) which are arranged on the concrete switch sleepers (1), backing plates (4) which are arranged between concrete switch sleepers (1) and steel frogs (2) and rails (3); connecting holes (5) on the backing plates (4). The utility model is characterized in that a concrete switch sleeper (1) is spliced by two or three slab sleepers (6) and is shaped non-shoulder; a slab sleeper (6) has at least one lateral inner hole (7) at one end of the rail; the steel bar (8) whose length is longer than the slab sleeper (6) is arranged in the inner hole (7); every two slab sleepers (6) are connected by the steel plate (8) which is arranged on the steel bar (9) through the holes at the two ends.
Description
The utility model relates to railway sleeper, especially belongs to switch sleeper.
As everyone knows, the sleeper that is adopted on the railway has three kinds at present: a kind of is sleeper, and its deficiency is to need a large amount of timber, does not meet the Policy Conditions of the relevant environmental protection of country, and rots easily, and maintenance is also big; Another kind adopts that concrete is integral prefabricated to form, though this kind sleeper has solved the problem of not using timber, owing to be integral prefabricated forming, make train cause the middle part hogging moment of switch tie excessive under steam, thereby influence its application life, and its body weight, specification many (reaching tens of kinds), give make, transportation, installation, replacing bring many difficulties, and labour intensity and maintenance are also very big; Though also have a kind of short switch tie of radial type splicing of once attempting to adopt, because its connected mode is horizontal, railway roadbed stress can not be improved, still there is the excessive problem of middle part hogging moment of switch tie, so do not applied.
The purpose of this utility model is to provide the no hogging moment in a kind of switch tie middle part, long service life, few, the easy manufacturing of manufacturing specification, transportation, the novel railway switch tie of installation, replacing.
The purpose of this utility model is achieved in that and mainly comprises the concrete sleeper plate, be installed in railway frog and rail on the concrete sleeper plate, be connected backing plate between concrete sleeper plate and railway frog and the rail, connect the novel railway switch ties such as connecting hole on the backing plate, be on the switch tie, for making switch tie middle part hogging moment little, long service life, easily make, transportation, installation, change, employing is spliced its concrete sleeper plate and for there not being " shoulder " shape by 2 or 3 pillow plate, the pillow plate has at least an end proximal head place that one lateral bore is arranged, reinforcing bar is housed in the endoporus, reinforcing bar is longer than the width of pillow plate, steel plate by be arranged at hole on its two ends be contained on the reinforcing bar will be per two rest the head on plates and couple together.
For guaranteeing the distance between the track, can regulate by the position that is provided with of the connecting hole on steel plate or buckle and the pillow plate.
This novel railway switch tie middle part hogging moment is little, long service life, manufacturing specification few (only 6 kinds of specifications), easily make, transportation, installation, replacing, labour intensity is little, maintenance is little, locomotive operation is steady.
Description of drawings is as follows:
Fig. 1 is the structural representation of novel railway switch tie
Fig. 2 is a structural representation by two sections splicings for the novel railway switch tie
Fig. 3 is a structural representation by three sections splicings for the novel railway switch tie
Be described in further detail as follows below in conjunction with accompanying drawing:
Mainly comprise concrete sleeper plate (1), be installed in railway frog (2) and rail (3) on the concrete sleeper plate (1), be connected backing plate (4) between concrete sleeper plate (1) and railway frog (2) and the rail (3), connect the connecting hole novel railway switch ties such as (5) on the backing plate (4), be on the switch tie, for making switch tie middle part hogging moment little, long service life, easily make, transportation, installation, change, employing is that length each concrete sleeper plate (1) in 2.6 meters～3.4 meters sections of railway switch and coupling part concrete sleeper plate (1) is spliced by 2 blocks of pillow plates (6) at narrow place, turnout, and the length of every block of pillow plate (6) is 1/2nd of every concrete sleeper plate of its section (1) total length.In this section, every block of pillow plate (6) only has an end to be embedded with a lateral bore (7) from the end, and reinforcing bar (8) is housed in the endoporus (7), and both belong to secure fit.And owing to length difference, so the pre-buried distance of vertical endoporus (7) from the end is 30～50 millimeters at every concrete sleeper plate of this section (1).The length that pillow plate (6) is stretched out at reinforcing bar (8) two ends is 20～25 millimeters, steel plate (9) by be embedded in hole (10) on its two ends be fixedly hinged reinforcing bar (8) go up will be per two rest the head on plates (6) and couple together.
The length that at wide place, turnout is railway frog and guard rail part concrete sleeper plate (1) is in 3.6 meters～4.8 meters sections, every concrete sleeper plate (1) is spliced by 3 blocks of pillow plates (6), and the length of every block of pillow plate (6) is 1/3rd of every required concrete sleeper plate (1) total length.In this section, every block of pillow plate (6) at every concrete sleeper plate (1) two ends only has an end to be embedded with a lateral bore (7) from the end, and middle pillow plate (6) two ends all are embedded with lateral bore (7) far from the end.Equally, reinforcing bar (8) is housed in the endoporus (7), both belong to secure fit.And owing to length difference, so the pre-buried distance of vertical endoporus (7) from the end is 30～50 millimeters at every concrete sleeper plate of this section (1).The length that pillow plate (6) is stretched out at reinforcing bar (8) two ends is 20～25 millimeters, steel plate (9) by be embedded in hole (10) on its two ends be fixedly hinged reinforcing bar (8) go up will be per two rest the head on plates (6) and couple together.Adopting bolt to be connected between rail (3) or railway frog (2) and pillow plate (6) is connected on the backing plate (4).Every root is nothing " shoulder " shape by the concrete sleeper plate (1) that pillow plate (6) splices.For guaranteeing the distance between the track, regulate with the set position of resting the head on the connecting hole (12) on the plate (6) by steel plate (9) or buckle (11).Note,, then just can't change again in case this set positions is good.
