Background

The sleeper is an important part of a railway track system, in particular to a ballast track, and not only supports a steel rail, transfers huge pressure transferred by the steel rail to a track bed, but also maintains the position of the steel rail, and has enough longitudinal and transverse resistance of the track bed. If the longitudinal and transverse resistances of the sleeper track bed are insufficient, the rail often crawls, the line deforms and is unstable, and the rail expansion runway occurs in serious conditions, so that the driving safety is influenced.

In the prior art, there are various ways to increase the longitudinal and transverse track bed resistance of a sleeper in a ballast track, for example, one way is to increase the width of the track bed and pile up ballast shoulders, but the construction cost is greatly increased due to the increase of the width of a roadbed and the use amount of the ballast. The other mode is that the ground anchor pull rod is installed on the side face of the steel rail to prevent the transverse movement of the steel rail from being unstable, but the ground anchor pull rod can influence the tamping operation of the railway ballast, the pull rod needs to be detached when the railway ballast is tamped, the tamping operation is completed and then the ground anchor pull rod is installed again, the process is complicated, and the maintenance workload is increased. In addition, the mode of increasing the longitudinal and transverse track bed resistance of the sleeper is to add an anticreeper at the bottom of the steel rail, but the anticreeper in the prior art has poor stability, limited action area and poor use effect.

As can be seen from the above, the method for increasing the longitudinal and transverse track bed resistance of the sleeper in the prior art has the disadvantages as described above, and therefore how to provide a better sleeper track bed resistance reinforcing device is a problem to be solved in the art.

Detailed Description

In order to make the technical solution and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, the utility model provides a device is strengthened to sleeper railway roadbed resistance includes: the transverse ballast blocking plate 4, the longitudinal ballast blocking plate 3, the fixing part 1 and the locking device 2 are arranged in the vertical direction;

the transverse ballast blocking plate 4 and the longitudinal ballast blocking plate 3 are perpendicular to each other and are fixedly connected;

the fixing part 1 is positioned at the top of the transverse ballast retaining plate 4, and the fixing part 1 comprises a short connecting plate 11 and a long connecting plate 12;

wherein, the first end of short circuit board 11 is fixed at the front end at 4 tops of horizontal fender tiny fragments of stone, and the first end of long fishplate bar 12 is fixed at the rear end at 4 tops of horizontal fender tiny fragments of stone, etc. board 11 and long fishplate bar 12 are all around the surface at sleeper 100, and the second end of short circuit board 11 meets with the second end of long fishplate bar 12 to through 2 fixed connection of locking device.

The technical scheme of the utility model in, through cup jointing connecting portion 1 and fixing on sleeper 100 for horizontal fender tiny fragments of stone, coal, etc. board 4 and vertical fender tiny fragments of stone, coal, etc. board 3 are located the railway ballast of sleeper 100 below, thereby can not influence the tamping car and carry out the tamping operation, and then need not extra maintenance work load. Because horizontal fender tiny fragments of stone, coal, etc. board 4 and vertical fender tiny fragments of stone, coal, etc. board 3 are perpendicular and fixed connection each other, so horizontal fender tiny fragments of stone, coal, etc. board 4 can increase the horizontal resistance that has the tiny fragments of stone, coal, etc. railway roadbed, vertical fender tiny fragments of stone, coal, etc. board 3 can increase the longitudinal resistance that has the tiny fragments of stone, coal, etc. railway roadbed resistance strengthens the device and possesses the function that increases vertical and horizontal railway roadbed resistance simultaneously, and horizontal fender tiny fragments of stone, coal, etc. board and vertical fender tiny fragments of stone, coal, etc. board direct and railway ballast bed contact, make fender tiny fragments of stone, coal, etc. area and atress area increase, further increased the vertical horizontal railway roadbed resistance of railway sleeper.

The technical scheme of the utility model in, can use multiple implementation method to realize foretell sleeper railway roadbed resistance and strengthen the device. The technical solution of the present invention will be described in detail below by taking one of the implementation modes as an example.

For example, in an embodiment of the present invention, as shown in fig. 2 and 3, the inner surface of the elongated connecting plate 12 may be provided with first saw-toothed structures 13 with spaced latch teeth and spaced latch grooves; the outer surface of the short connecting plate 11 can be provided with a second sawtooth-shaped structure 14 matched with the first sawtooth-shaped structure 13 on the long connecting plate 12, and the first sawtooth-shaped structure 13 and the second sawtooth-shaped structure 14 are clamped and fixed.

The technical scheme of the utility model among, through set up first cockscomb structure 13 on long fishplate bar 12's internal surface to not only can realize the fixed connection of long fishplate bar and short fishplate bar, can also increase the frictional resistance between long fishplate bar 12's internal surface and the sleeper 100, thereby it is more firm to make to be connected between fixed part 1 and the sleeper 100. In addition, as the service life increases, when looseness occurs between the fixing portion 1 and the sleeper 100, the whole sleeper track bed resistance reinforcing device does not need to be removed for replacement or repair. Because first sawtooth structure 13 and second sawtooth structure 14 are the matching joint to can make long fishplate bar and short circuit board chucking again through the second end of the reverse pulling long fishplate bar 12 and the second end of short fishplate bar 11 (for example, can upwards stimulate the second end of short fishplate bar, the second end of the long fishplate bar of pulling downwards), thereby can only through the joint position of adjusting long fishplate bar and short fishplate bar, just can realize the fastening connection between fixed part and the sleeper again, easy and simple to handle and prolonged whole sleeper railway roadbed resistance reinforcing means's life.

Furthermore, as an example, in a preferred embodiment of the present invention, as shown in fig. 4, the locking device 2 may include: a connecting portion 21, a fastening bolt, and a nut;
