Technical Field

[0001] The present invention belongs to the technical field of rail transit, and particularly relates to a mechanical adaptive regulation system for tracks under the dislocation of a cross-active fault tunnel. Background Art

[0002] It is inevitable for a tunnel to cross an active fault. For high-speed railway tunnels, the fault dislocation has an important impact on the tunnel and the facilities inside the tunnel. Since the deformation requirements for the track of high-speed rail are very high, relevant measures need to be adopted to realize the real-time adjustment of the deformation of the track structure when the tunnel crosses an active fault.

[0003] That is, at present, there is no effective measure for high-speed rail tracks under disturbance to enable the misaligned track after disturbance to be automatically reset, which thus causes potential safety risks for high-speed rail operation.

[0004] It can be seen that how to optimize the reset measure for high-speed rail tracks after being disturbed and misaligned, and thus improve the safety of high-speed rail operation, is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0007] In the first aspect, the gear transmission structure includes: a bevel gear and a disk with an arc-shaped tooth surface, one end of the disk is connected to the outer contour of the turntable; the bevel gear is coaxially sleeved on the push rod, and the bevel gear is drivingly connected to the disk.

[0008] In a first aspect, two ends of the push rod are correspondingly connected to the lining through a pair of pins, and the two ends of the push rod can rotate freely with respect to the corresponding pins.

[0009] In the first aspect, an inclined connecting rod is further included; one end of the inclined connecting rod intersects with one end of the transverse connecting rod located on the turntable and is connected to the turntable through the rotating bearing, and the other end of the inclined connecting rod is connected to an adjacent lining.

[0010] In the first aspect, the chute is crescent-shaped and arranged around the center of the turntable.

[0033] Embodiment 1:

[0034] As shown Figures 1-4 in the figure, Embodiment 1 of the present invention provides a mechanical adaptive regulation system for tracks under the dislocation of a cross-active fault tunnel. The adaptive regulation system is laid between the track slab and the lining; the adaptive regulation system includes: a turntable 6 provided between each section of the lining 1 and the track slab, the turntable 6 is rotatably connected to the lining 1, and an arc-shaped chute 601 is provided on the turntable 6 and arranged around the center of the turntable 6; a cross-link 10, one end of the cross-link 10 is connected to an adjacent lining 1, and the other end of the cross-link 10 is connected to the chute 601 of the turntable 6 through a rotating bearing 7; a push rod 5, both ends of the push rod 5 are correspondingly arranged on the lining 1, both ends of the push rod 5 are rotatable with respect to the connection ends with the lining 1, the push rod is a threaded rod, and a transmission nut threadedly connected to the threaded rod is arranged on the threaded rod, and the outer side of the transmission nut abuts against the track slab; 8; a gear transmission structure, the gear structure is connected between the push rod 5 and the turntable 6, the connection position of the gear transmission structure and the turntable 6 is located on the outer contour of the turntable 6, and the gear transmission structure is fixedly connected to the push rod 5.

[0035] Specifically, in Embodiment 1 of the present invention, adjacent pairs of linings 1 are connected by a cross-link 10, and one end of the cross-link 10 is slidably connected to the chute 601 of the turntable 6 through a rotating bearing. When the lining 1 is displaced, the turntable 6 is rotated based on the position of the previous undisturbed lining 1 by the cross-link 10, so that the gear transmission structure connected to the turntable 6 is driven, and then the push rod 5 is driven to rotate. By transmitting through the push rod and the transmission nut, the transmission nut remains stationary relative to the lining, so that the track slab does not rotate, and thus the technical effect of improving the running safety of high-speed trains is achieved.

[0036] In other words, after the fault is dislocated, the tunnel is deformed and the lining 1 is dislocated, driving the turntable 6 to move. Due to the constraint of the cross-link 10 (the cross-link 10 is fixed on the track slab of the previous section of the lining 1 and uses the previous section of the lining 1 as the reference lining 1, that is, the target object for callback), the turntable 6 rotates along the chute 601 and drives the transmission gear 4 to rotate. Through the connection and transmission action of the bevel gear 3, the push rod 5 is driven to rotate, so that the track slab is brought back by the transmission nut 8, and finally the track slab returns to the initial position, and the relative position of the track remains unchanged, so as to achieve the purpose of the safe operation of high-speed trains.

[0037] In some possible implementation manners, the gear transmission structure includes: a bevel gear 3 and a wheel disc with an arc-shaped tooth surface, one end of the wheel disc is connected to the outer contour of the turntable 6; the bevel gear 3 is coaxially sleeved on the push rod 5, and the bevel gear 3 is in transmission connection with the wheel disc.

[0038] In the implementation manner of the above embodiment, for the gear transmission structure, it transmits power through the bevel gear 3 and the disk with an arc-shaped tooth surface. The conical surface of the bevel gear 3 forms a transmission fit with the arc surface of the arc-shaped tooth surface, thereby making the transmission method more matching and stable.

[0039] In some possible implementation manners, both ends of the push rod 5 are correspondingly connected to the lining 1 through a pair of pins 2, and the two ends of the push rod 5 can rotate freely with respect to the corresponding pins 2.

[0040] This is to limit the position of the push rod 5 through a pair of pins 2 and provide a free rotation environment for the push rod 5 through the pins 2.

[0041] In some possible implementation manners, the reset device further includes an inclined connecting rod 9; one end of the inclined connecting rod 9 intersects with one end of the cross connecting rod 10 on the turntable 6 and is connected to the turntable 6 through a rotating bearing 7, and the other end of the inclined connecting rod 9 is connected to an adjacent lining 1.

[0042] By providing the inclined connecting rod 9, the connection stability between two adjacent linings 1 is enhanced. The inclined connecting rod 9, the cross connecting rod 10, and the lining 1 form a triangle, thereby making the connection more stable.

[0043] In some possible implementation manners, the chute 601 is crescent-shaped and arranged around the center of the turntable 6.

[0044] The crescent shape is arranged in an arc around the center of the turntable 6.

[0045] In some possible implementation manners, the thread of the first section is set with a gradually changing pitch.

[0046] In this way, the callback speed of the lining 1 can be accelerated through the change of the gradually changing pitch.

[0047] In some possible implementation manners, the chute 601 is a straight line shape obliquely arranged on the turntable 6; the cross connecting rod 10 is composed of a pair of hinged connecting rods, and a transmission bearing is arranged at the hinged position; the transmission bearing is arranged in the chute 601 and can slide along the chute 601.

[0048] Furthermore, the starting end of the straight chute 601 is located at the center of the turntable 6, and the end of the chute 601 is located at the edge of the turntable 6.

[0049] In the above technical solution, after the fault dislocation occurs, the tunnel is deformed, the lining 1 is dislocated, driving the turntable 6 to move. Due to the restraint of the telescopic cross-link 10 (the telescopic cross-link 10 is fixed on the track slab of the previous lining 1, and the previous lining 1 is used as the reference lining 1, that is, the target object for callback, and the length of the cross-link 10 can be selected according to the position of the rotating bearing 7), the turntable 6 rotates around the rotating bearing 7 and drives the transmission gear 4 to rotate. Through the connection and transmission of the bevel gear 3, the push rod 5 rotates, and thus the track slab is brought back by the transmission nut 8. Since the compensation function generated during the rotation process is non-linear, according to the transmission ratio calculation of the mechanical structure, the theoretical solution of the variable pitch on the push rod 5 can be obtained to ensure that the final track slab returns to the initial position during the real-time adjustment process, and the relative position of the track remains unchanged, so as to achieve the purpose of the safe operation of high-speed railways.

[0050] In some possible embodiments, a slider is further prominently provided at the axial center position of the transmission bearing, and the slider is adapted to the chute 601.

[0051] This enables the bearing not to interfere with the chute 601 during rotation, thereby affecting the rotation efficiency of the bearing.

[0053] The present invention provides a track self-adaptive reset system under the dislocation of a cross-active fault tunnel. The reset system includes the above-mentioned track mechanical self-adaptive regulation system under the dislocation of a cross-active fault tunnel. By means of the reset device, it is achieved that: after the fault dislocation occurs, the tunnel is deformed, the lining 1 is dislocated, driving the turntable 6 to move. Due to the restraint of the cross-link 10 (the cross-link 10 is fixed on the track slab of the previous lining 1, and the previous lining 1 is used as the reference lining 1, that is, the target object for callback), the turntable 6 rotates along the chute 601 and drives the transmission gear 4 to rotate. Through the connection and transmission of the bevel gear 3, the push rod 5 rotates, and thus the track slab is brought back by the transmission nut 8. Finally, the track slab returns to the initial position, and the relative position of the track remains unchanged, so as to achieve the purpose of the safe operation of high-speed railways.
