Abstract
The invention provides a wood sleeper elastic strip fastener used for a meter-gage railway. The wood sleeper elastic strip fastener comprises elastic strips (5), locknuts (6), T-type bolts (7), gauge blocks (8) and a backing plate below a rail (9), wherein the backing plate below the rail (9) is composed of a rubber backing plate and a composite backing plate, the wood sleeper elastic strip fastener is connected with a connecting piece used for connecting a wood sleeper and the wood sleeper elastic strip fastener, the connecting piece comprises a backing plate below a plate (1), an iron backing plate (2), heavy-duty spring washers (3) and screw spikes (4), the backing plate below the plate (1) is arranged below the iron backing plate (2), and the heavy-duty spring washers (3) are arranged between the screw spikes (4) and the iron backing plate (2). The elastic strip fastener is an elastic split fastener and firm in linkage, can ensure that the steel rail is stressed reasonably and provides elasticity for a rail system, so that positioning on the steel rail through the fastener is reliable, and the fastener is convenient to replace, can play a role in insulation and has the advantages of reducing repairing and maintaining cost and the like.
Description
Technical field
the present invention relates to a kind of wooden sleeper elastic bar fastener for rice rail, belong to technical field of traffic transportation.
Background technology
Each was all breaking into railway construction both at home and abroad energetically in recent years, but 1000 millimeters of gauge meter gage railway systems of the most of employing of many countries, for catering to domestic and international market, separately because Chinese II type sleeper is features large according to heavy-haul line bearing load, that number of repetition is many, adopt fatigue reliability to design, at experience and technical elements comparative maturity.So the ad hoc metering rail of size II type wooden sleeper with reference to Chinese II type wooden sleeper.
In existing Chinese II type sleeper, railway spike is directly fixed on concrete sleeper and can not pulls down, and can only change II type sleeper during railway spike damage parts, and this is to cause that maintenance cost is high, inconvenient operation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of wooden sleeper elastic bar fastener for rice rail is provided.
Wooden sleeper elastic bar fastener for rice rail of the present invention, comprise spring (5), locknut (6), T-shaped bolt (7), track gauge block (8) and railway rail pad (9), described railway rail pad (9) is comprised of rubber mat plate and compound backing plate, on described wooden sleeper elastic bar fastener, be connected with the connector for connected wood sleeper and wooden sleeper elastic bar fastener, described connector comprises plate lower bolster (1), iron chair (2), heavy-duty spring packing ring (3) and screw spike (4), described plate lower bolster (1) is located at iron chair (2) below, described heavy-duty spring packing ring (3) is located between screw spike (4) and iron chair (2).
Described screw spike (4) has four.
Wooden sleeper elastic bar fastener for rice rail of the present invention, has following technique effect:
1) fastening with four screw spikes between iron chair and sleeper, compare with conventional spike, connect more firm;
2) iron chair Main Function is to spread pressure in the larger area of sleeper, in order to avoid sleeper is damaged by pressure.Backing plate is provided with the Gui Di slope of 1:40, to guarantee rail reasonable stress;
3) at the bottom of Rail and between iron chair, establish rubber mat plate, to reduce impact shock, and provide the elasticity of rail system.Bear the effect of vertical force, lateral force and longitudinal force from rail.Resilient sleeper-bearing under rail, has in length and breadth to shoulder block and rib platform, and when bearing the lateral force that rail transmits, unlikely railway rail pad is scurried out.
4) this elastic bar fastener is elasticity separated rail fastening, connects firmly, can guarantee rail reasonable stress, and the elasticity of rail system is provided, and makes fastener reliable to the location of rail, is convenient to change, and can play the advantages such as insulating effect and maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structure of the wooden sleeper elastic bar fastener for rice rail of the present invention and uses view.
Wherein, 1 is plate lower bolster, and 2 is iron chair, and 3 is heavy spring washer, and 4 is screw spike, and 5 is spring, and 6 is locknut, and 7 is T-shaped bolt, and 8 is track gauge block, and 9 is railway rail pad, and 10 is sleeper, and 11 is rail.
The specific embodiment
As shown in Figure 1, wooden sleeper elastic bar fastener for rice rail of the present invention, comprise spring (5), locknut (6), T-shaped bolt (7), track gauge block (8) and railway rail pad (9), described railway rail pad (9) is comprised of rubber mat plate and compound backing plate, on described wooden sleeper elastic bar fastener, be connected with the connector for connected wood sleeper and wooden sleeper elastic bar fastener, described connector comprises plate lower bolster (1), iron chair (2), heavy-duty spring packing ring (3) and screw spike (4), described plate lower bolster (1) is located at iron chair (2) below, described heavy-duty spring packing ring (3) is located between screw spike (4) and iron chair (2).
Described screw spike (4) has four.
Product technology parameter is as follows:
1, the longitudinal anti-creep resistance of single elastic bar fastener is not less than 10kN/m;
2, roll adjustment amount-12 ~+8mm; Adjustment rank is 2mm;
3, spring is withheld by T-shaped bolt, twists solid moment approximately 120 Nm;
4, the quiet rigidity of fastener node is 80 ~ 110kN/mm.
It is 1000mm that wooden sleeper elastic bar fastener of the present invention is applicable to gauge, radius R >=250m curve track and rectilinear orbit.Meet driving demand: overall trip speed is 90km/h requirement, the heavy 22t of axle.
When practical application, the iron chair (2) that rail (11) is fixed on to the wooden sleeper of meter rail by T-shaped bolt (7) and locknut (6), spring (5), track gauge block (8), railway rail pad (9) is upper, fastening with screw spike between iron chair (2) and sleeper (10).Its structure is applicable to UIC54 rail.
Claims (2)
1. the wooden sleeper elastic bar fastener for rice rail, it is characterized in that, comprise spring (5), locknut (6), T-shaped bolt (7), track gauge block (8) and railway rail pad (9), described railway rail pad (9) is comprised of rubber mat plate and compound backing plate, on described wooden sleeper elastic bar fastener, be connected with the connector for connected wood sleeper and wooden sleeper elastic bar fastener, described connector comprises plate lower bolster (1), iron chair (2), heavy-duty spring packing ring (3) and screw spike (4), described plate lower bolster (1) is located at iron chair (2) below, described heavy-duty spring packing ring (3) is located between screw spike (4) and iron chair (2).
