Abstract
The utility model provides a force transmission pin-type double-layer tie plate structure for a railway switch, which comprises a railroad rail spacing iron seat which is allocated on a tie plate and a switch sleeper bolt which is allocated on both sides of the tie plate, wherein the tie plate is formed by an upper plate, a lower plate and an elastic cushion layer which is clamped between the upper plate and the lower plate, a force transmission pin shaft is arranged under the upper plate, the lower plate is provided with a pin shaft hole which is matched with the force transmission pin shaft, the pin shaft hole is eccentrically arranged relative to the central line between two switch sleeper bolt holes, and a switch sleeper bolt hole which is allocated by the upper plate is a transverse growing round hole. The force transmission pin-type double-layer tie plate structure can achieve the inward and great adjustment of track space through rotating the lower plate in 180 degrees in a horizontal direction, and can satisfy the adjusted requirement of the railway switch to the track space. The utility model has the advantages of low force-bearing point of a switch sleeper bolt, transverse force, rigid transmission and excellent track space stability, which can effectively improve the force condition of the switch sleeper bolt, can utilize a rubber spacer under a plate to effectively absorb vertical vibration, and protect the foundation under rails.
Description
Technical field
The utility model relates to railway turnout base plate, is specifically related to a kind of power transmission pin formula two-layer pad plated construction.
Background technology
Existing railway turnout base plate is the one-board structure, and the adjustment of gauge mainly realizes that by replacing track gauge block of different size between rail and iron seat adjusting precision is ± 2mm that maximum adjustment amount is 6mm.In the process of railway operation, because gauge situation bigger than normal can appear in the abrasion of rail inboard; On the other hand, when producing than mistake, also can make the gauge deviation excessive,, can't satisfy the requirement that track switch is adjusted gauge to the inside on a large scale if only rely on track gauge block adjustment when initial laying or in concreting process.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of and is convenient to realize that track switch adjusts the power transmission pin formula two-layer pad plated construction of gauge to the inside on a large scale.
The technical scheme that realizes above-mentioned purpose is: a kind of power transmission pin formula two-layer pad plated construction, include rail limiting iron seat that is disposed at above the backing plate and the turnout sleeper bolt that is disposed at the backing plate both sides, its described backing plate is made up of upper plate, lower plate and the elastic layer that is folded in therebetween, be provided with the power transmission bearing pin below the upper plate, lower plate is provided with the pin shaft hole that matches with the power transmission bearing pin, and this pin shaft hole becomes eccentric with respect to center line between two turnout sleeper bolt holes and is provided with; The turnout sleeper bolt hole that its upper plate disposed is horizontal slotted hole.
The utility model adopts the eccentric double-deck backing plate power transmission pin assembly structure that is provided with of lower plate pin shaft hole, and the upper plate effect is consistent with existing switch bed plate, be to rail spare spacing be connected, and bear suffered power of rail spare or moment.Lower plate mainly is spacing by the turnout sleeper bolt pair to whole fastener system, and the power that upper plate is subjected to is passed to the turnout sleeper bolt pair.When using the track gauge block adjustment not reach the gauge adjustment when requiring, by with lower plate horizontal direction Rotate 180 °, during centerline offset 5mm between power transmission pin shaft hole and two turnout sleeper bolt holes, can realize that gauge inwardly once adjusts 5mm, use together in conjunction with the different size track gauge block, can reach gauge and inwardly adjust 11mm, outwards adjust 4mm, the adjustment amount of precision ± 1mm.
The lateral force that rail is subjected to is passed to lower plate by upper plate power transmission pin, passes to turnout sleeper bolt by lower plate again.This structure reduces the turnout sleeper bolt stress point, can effectively improve the force-bearing situation of turnout sleeper bolt and nylon sleeve.Simultaneously because lateral stressed rigid of transmission can make the gauge variation reduce to minimum.
The vertical force that rail is subjected to after the rubber pad placed under-neath rail buffering, is directly passed to rubber spacer under the plate by upper plate, can effectively absorb vertical vibration, the protection sub rail foundation.
Description of drawings
Fig. 1 is this power transmission pin formula two-layer pad plated construction master sectional view;
Fig. 2 is this backing structure vertical view.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, this power transmission pin formula two-layer pad plated construction includes rail limiting iron seat 1 that is disposed at above the backing plate and the turnout sleeper bolt 2 that is disposed at the backing plate both sides, its backing plate is made up of upper plate 3, lower plate 4 and the elastic layer 5 that is folded in therebetween, be provided with power transmission bearing pin 6 below the upper plate 3, lower plate 4 is provided with the pin shaft hole that matches with the power transmission bearing pin, and this pin shaft hole becomes eccentric with respect to center line between two turnout sleeper bolt holes and is provided with.The turnout sleeper bolt hole that upper plate 3 is disposed is horizontal slotted hole.
When the utility model was specifically implemented, power transmission bearing pin 6 can be one-body molded with upper plate 3, also can adopt processing back assembly welding all-in-one-piece production technology respectively.
Claims (1)
1, a kind of power transmission pin formula two-layer pad plated construction, include rail limiting iron seat (1) that is disposed at above the backing plate and the turnout sleeper bolt (2) that is disposed at the backing plate both sides, it is characterized in that: described backing plate is made up of upper plate (3), lower plate (4) and the elastic layer (5) that is folded in therebetween, be provided with power transmission bearing pin (6) below the upper plate (3), lower plate (4) is provided with the pin shaft hole that matches with the power transmission bearing pin, and this pin shaft hole becomes eccentric with respect to center line between two turnout sleeper bolt holes and is provided with; The turnout sleeper bolt hole that its upper plate disposed is horizontal slotted hole.
