Description

Technical Field

[0001] The present invention belongs to the technical field of railway tracks, and more specifically, relates to an anti-climbing device for a railway track system. Background Art

[0002] When the rail is bent by the dynamic load of the locomotive, the rail section rotates, the rail top is shortened, and the rail bottom is elongated. If the rail is not firmly connected to the sleeper, the rail will bend when subjected to the vehicle axle load. The rotation of the rail section in front of the wheel causes the rail bottom to slide on the pad along the driving direction, causing creeping. Creeping is one of the important reasons for track damage. It can cause the sleeper position to be skewed, the spacing to be incorrect, and the track joints to be uneven, which is very destructive to the line. Rail creep not only causes joint diseases in the joint sleepers, but also the displacement of other sleepers causes changes in the geometric dimensions of the line.

[0003] The traditional measures to prevent track creeping are to strengthen the buckling pressure of the middle fasteners of the track and the clamping force of the joint clamps, and use anti-climbing equipment consisting of anti-climbing devices and anti-climbing supports to jointly resist rail creeping. Gauge rods or rail supports can also be installed. However, the anti-climbing devices of general railway tracks all use a pin-through method to fix the rails. Wedge nails are driven into the ground at the connection between the rails and the sleepers to achieve the effect of fixing the tracks. However, this method requires the wedge nails to be driven into a deeper soil layer to fix the tracks, which consumes more manpower and resources to fix the rails. At the same time, the inserted wedge nails cannot restrain each other. During long-term use, the wedge nails will become loose under long-term vibration conditions, resulting in a short service life of the wedge nails fixing the rails. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1As shown, the railway track system includes a track plate 1, a plurality of sleepers 2 laid on the track plate 1, and two rails 3 laid on the sleepers 2, with the extension direction of the track as the longitudinal direction, and the direction perpendicular to the longitudinal direction in a plane parallel to the track surface as the transverse direction. Specifically, the sleepers 2 are arranged transversely and are provided in plurality, and the plurality of sleepers 2 are arranged longitudinally and equidistantly on the upper surface of the track plate 1, and the rails 3 are arranged longitudinally and are provided in plurality, and the two rails 3 are respectively provided on the transverse sides of the upper surface of the sleepers 2.

[0025] like Figures 1 to 4 As shown, a preferred embodiment of the present invention is an anti-climbing device for a railway track system, which includes at least one pair of anti-climbing devices 4 arranged in a laterally symmetrical manner, the anti-climbing device 4 includes an anti-climbing base 41 and a force transmission pad 42, the anti-climbing base 41 is arranged at the bottom of the rail 3 and is located between two adjacent sleepers 2, the longitudinal side end surfaces of the anti-climbing base 41 are respectively fitted and abutted against the longitudinal end surfaces of the two adjacent sleepers 2, the force transmission pad 42 is connected to the upper end of the anti-climbing base 41, and the force transmission pad 42 is symmetrically fitted on the side surfaces and bottom of the rail 3. Therefore, the anti-climbing device of the present invention changes the traditional wedge-shaped nail method to fix a small section of the rail 3 between the sleepers 2. Through the setting of the anti-climbing device 4, the entire anti-climbing base 41 is inserted between two adjacent sleepers 2, thereby increasing the overall supporting capacity of the rail 3, and the contact surface between the sleeper 2 and the anti-climbing base 41 is adapted (fitted against each other). At the same time, through the setting of the force transmission pad 42, the force-bearing area of ​​the rail 3 is increased, and the overall friction of the rail 3 is improved, thereby effectively reducing the possibility of longitudinal movement of the rail 3 and greatly improving the stability of the rail 3.

[0026] Based on the above embodiment, the anti-climbing device also includes at least one pair of fixers 5 arranged in a transverse symmetrical manner, and the fixers 5 correspond one-to-one to the anti-climbing devices 4. The fixers 5 include a fixing rod 51, a clamping rod 52 and a connecting column 53. The fixing rod 51 is a rectangular rod, and the fixing rod 51 is placed longitudinally and is located on the outside of the two adjacent sleepers 2. The clamping rods 52 are provided with two and are respectively vertically connected to the longitudinal ends of the fixing rod 51. The two clamping rods 52 are respectively fitted and abutted against the other longitudinal end surface of the two adjacent sleepers 2 away from the anti-climbing base 41. The connecting column 53 is vertically connected to the middle part of the fixing rod 51, and the transverse end surface of the anti-climbing base 41 is provided with a welding hole 43 connected to the end of the connecting column 53. Therefore, by setting the fixing device 5 and the welding hole 43 on the anti-climber 4, the fixing device 5 is matched with the anti-climber 4, and while the anti-climber 4 fixes the rail 3, the fixer 5 further fixes the sleeper 2 and the rail 3, so that the sleeper 2 and the rail 3 are entangled with each other during the operation of the train, thereby increasing the restriction on the track, and no loosening will occur during long-term use, thereby improving the service life of the overall anti-climber device.

[0027] Exemplarily, the clamping rod 52 is provided with a fitting surface 54 that fits against the longitudinal end surface of the sleeper 2, thereby increasing the force bearing area of ​​the clamping rod 52 and the sleeper 2 and ensuring the clamping force of the clamping rod 52 on the sleeper 2. To prevent the fitting surface 54 from slipping, the fitting surface 54 is provided with concave and convex patterns.

[0028] For example, one end of the clamping rod 52 is connected to a cylinder 55, the longitudinal end of the fixing rod 51 is provided with a circular hole 56 slidably connected to the cylinder 55, and the fixing rod 51 is provided with a limiting member for fixing the telescopic length of the cylinder 55. Due to the adaptation of the circular hole 56 and the cylinder 55, the fixing device 5 can adjust the distance between the two clamping rods 52 according to the distance between different sleepers 2 during use, so as to fix the sleepers 2 to adapt to the spacing between sleepers 2 of different specifications, thereby improving the application range of the anti-climbing device. In this embodiment, the limiting member is preferably a screw 57, and the fixing rod 51 is provided with a threaded hole 58 connected to the screw 57, and the end of the screw 57 passes through the threaded hole 58 and is pressed against the outer circumference of the cylinder 55; to prevent the screw 57 from loosening, the head of the screw 57 faces the lateral end surface of the sleeper 2, and after the fixer 5 is installed, the head of the screw 57 is against the lateral end surface of the sleeper 2; in addition, to prevent the head of the screw 57 from causing pressure damage to the fixing rod 51 when the screw 57 is tightened, a pad 59 is provided between the head of the screw 57 and the fixing rod 51.

[0029] Exemplarily, the area between two adjacent sleepers 2 is taken as a section. Except for the section with the anti-climber 4 and the fixer 5, the remaining sections are all provided with fixing blocks 6. The longitudinal side end faces of the fixing blocks 6 are respectively fitted against the longitudinal end faces of the two adjacent sleepers 2. In this embodiment, in order to save costs, the fixing blocks 6 are only provided in several continuous sections on both sides of the longitudinal direction close to the anti-climber 4 section. Thus, through the provision of the fixing blocks 6, multiple sleepers 2 on a section of track can be fixed at the same time, so that the anti-climber 4 section and several continuous sections on both sides of the longitudinal direction constitute regional reinforcement, share the load of the anti-climber 4 and the fixer 5 when they are working, further increase the restriction force on the track, and improve the service life of the overall anti-climber device.

[0030] Exemplarily, the longitudinal cross-section of the anti-climbing base 41 is an inverted trapezoid, and the longitudinal cross-section of the sleeper 2 is a regular trapezoid.

[0031] Exemplarily, a vibration-damping pad 44 is provided between the longitudinal end surface of the anti-climbing base 41 and the longitudinal end surface of the sleeper 2 to achieve vibration reduction treatment of the rail 3. Specifically, the vibration-damping pad 44 is bonded to the longitudinal end surface of the anti-climbing base 41.

[0032] Exemplarily, to facilitate the installation of the anti-climbing device 4, the anti-climbing base 41, the force transmission pad 42 and the rail 3 are fixedly connected by bolts 45. Specifically, at least one pair of first fixing holes are symmetrically provided on both sides of the force transmission pad 42, at least one pair of second fixing holes are symmetrically provided on both sides of the rail 3, and at least one pair of threaded holes are symmetrically provided on both sides of the anti-climbing base 41. The first fixing hole, the second fixing hole and the threaded hole are adapted to communicate with each other in sequence, and the bolt 45 passes through the first fixing hole, the second fixing hole and the threaded hole in sequence to be fixedly connected. Furthermore, to prevent the bolt 45 from loosening, an anti-slip pad 46 is provided between the head of the bolt 45 and the force transmission pad 42.

[0033] Exemplarily, the anti-climbing base 41 and the force transmission pad 42 are integrally formed.

[0034] Exemplarily, an elastic pad 7 is provided at the connection between the steel rail 3 and the sleeper 2, and the steel rail 3, the sleeper 2 and the elastic pad are fixed together by connecting components (such as spiral spikes, fasteners, etc.). Therefore, the provision of the elastic pad 7, on the one hand, reduces the degree of hard impact between the sleeper 2 and the steel rail 3 when the train passes over the steel rail 3, and protects the sleeper 2 and the steel rail 3 to a certain extent; on the other hand, it reduces the relative displacement of the steel rail 3 when the train passes over the steel rail 3, so that the possibility of the steel rail 3 being deviated will be smaller than when the elastic pad is not added, and the degree of deviation of the steel rail 3 is curbed from the source.

[0035] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
