Description

Technical Field

[0001] The invention relates to the technical field of railway transportation equipment, in particular to an automatic adjustment device for the settlement of a railway fastener bearing rail groove. Background Art

[0002] Railway tracks directly support the wheels and guide trains. Track geometry must closely align with the geometry of rolling stock wheelsets, making track geometry control crucial for ensuring train safety. Furthermore, with increasing train speeds and the application of high-speed rail technology, strict control of track geometry is also essential to maintain smooth and comfortable operation.

[0003] However, the impact of line foundation settlement on the geometric stability of the track is very significant. If local subsidence, uneven settlement and other problems occur during the operation of the line, it will cause further track unevenness, accelerate the deterioration of the track line condition, shorten the maintenance cycle of the track line, increase the maintenance cost of the track line, and in serious cases it is very likely to threaten driving safety.

[0004] In terms of maintaining the geometric shape of the track, the fastener rail groove is the part of the sleeper (track bed) structure that directly fixes the rail. Its function is to constrain the geometric position of the rail and withstand the impact load of the train. Generally speaking, it is very difficult to adjust the settlement value of the line foundation (roadbed, bridge and tunnel) after the construction is completed. The current common method is to manually test the settlement value and then use pads of different thicknesses to adjust the height of the fastener rail groove. The adjustment value is equal to the elevation drop of the rail caused by the foundation settlement. For areas with poor geology, transition sections and other areas with large uneven settlement, the manual method requires replacing the height adjustment pads of the corresponding elevation for each fastener rail groove part. The workload is large, and it is difficult to deal with the defects in time under conditions of intensive traffic. Therefore, it is considered to design an automatic adjustment device for the settlement of railway fastener rail grooves to more efficiently solve the shortcomings of the existing technology.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This railway fastener rail groove settlement automatic adjustment device utilizes an elastic support mechanism consisting of a spring, an elastic diagonal rod mechanism, and a horizontal guide buffer mechanism. When the device body is subjected to a downward impact, the impact acts on the internal top plate, which squeezes downward. The elastic support mechanism buffers and offsets the impact load on the device body, thereby effectively buffering the wheel-rail impact and providing a certain degree of elasticity for the track as a whole. At the same time, the triangular structure of the structure effectively maintains its stability, allowing the force applied to the device body to be evenly distributed by the structure, ensuring the long-term use of the structure and the device body.

[0018] 2. This railway fastener rail groove settlement automatic adjustment device is provided with an elastic adjustment mechanism, a transverse elastic reset mechanism, a vertical movable block, and a horizontal movable block. When a train passes over the rails, a downward force is generated and transmitted to the roadbed by the rails, the vertical movable block, the horizontal movable block, the elastic adjustment mechanism, and the device body. At this time, the two oblique sides of the vertical movable block are tightly fitted with the oblique sides of the horizontal movable block, so that the device body moves together with the rails. If the roadbed or roadbed settles, the device body will also settle. At this time, the rails will exert an upward pulling force on the rail groove due to the constraint of the long rail bar, thereby driving the oblique sides of the vertical movable block connected to it to separate from the horizontal movable block. Under the reverse force of the transverse elastic reset mechanism, it helps to push it to maintain its initial position, so that the rails can continue to maintain their initial state. At the same time, when the vertical movable block is relatively lifted, the elastic adjustment mechanism and the transverse elastic reset mechanism rebound and reset, further helping to push the rails to return to their initial state, thereby forming an initial mechanical equilibrium system. When the train wheels pass by, if the roadbed does not sink, the various parts will not move, the overall height of the device will remain unchanged, and the downward force transmitted will not change the relative position of the device body and the roadbed; if the roadbed sinks, the above adjustment process will be repeated again. The setting of this structure can effectively prevent the device body from sinking, and at the same time offset the settlement. At the same time, the coordination of multiple structures can achieve the effect of automatic adjustment of settlement, which can play a good role in maintaining the track shape and position, and reduce the frequency of replacement of height adjustment pads.

The two sides are fixedly connected with a bearing seat 16, and a slide groove 23 is provided on the upper surface of each bearing seat 16. Slide blocks 24 are slidably connected on both sides of the inner part of the slide groove 23. The upper surface of the slide block 24 is fixedly connected with a horizontal movable block 22. The two horizontal movable blocks 22 are distributed on both sides of the vertical movable block 21. The inclined surfaces of the two horizontal movable blocks 22 cooperate with the inclined surfaces of the vertical movable block 21. The lower surface of the vertical movable block 21 is fixedly connected with a moving rod 20, and the outer surface of the moving rod 20 is slidably connected with a fixed sleeve rod 19. The lower end of the fixed sleeve rod 19 is fixedly connected to the inner lower surface of the slide groove 23. An elastic adjustment mechanism is installed inside the fixed sleeve rod 19 and at the lower end of the moving rod 20. A lateral elastic reset mechanism is arranged between the two horizontal movable blocks 22 on both sides of the same vertical movable block 21.

[0027] The lateral elastic reset mechanism is composed of a carrying frame 13, an elastic column 14, a spring 2 15, etc., and a slot 18 is provided at both ends of the outer side of the horizontal movable block 22. Both sides of the horizontal movable block 22 are fitted with a plate 12, and the opposite side of the plate 12 is fixedly connected to the carrying frame 13. The inner end of the carrying frame 13 is fixedly connected to the elastic column 14, and the outer surface of the elastic column 14 is sleeved with the spring 2 15. The end of the spring 2 15 is fixedly connected to the inner end of the carrying frame 13, and the other side of the plate 12 is fixedly connected to an L-shaped block 17. The outer surface of the L-shaped block 17 is engaged with the inner wall of the slot 18.

[0028] The elastic adjustment mechanism is composed of an elastic column 26 and a spring 3 27. The inner lower surface of the fixed sleeve rod 19 is fixedly connected to the elastic column 26, and the outer surface of the elastic column 26 is sleeved with the spring 3 27. One end of the spring 3 27 is fixedly connected to the inner lower surface of the fixed sleeve rod 19, the upper end of the elastic column 26 is fixedly connected to the lower end of the movable rod 20, and the other end of the spring 3 27 is fixedly connected to the lower end of the elastic column 26.

[0029] When the line foundation sinks, the device body 1 will move downward as a whole, and the rail 2 will remain in its original position due to the limitation of the long rail. At this time, the rail 2 drives the vertical movable block 21 to move upward relative to the device body 1, and the two side oblique edges of the vertical movable block 21 fit with the oblique edges of the horizontal movable block 22. In the process of the vertical movable block 21 moving upward, the horizontal movable blocks 22 on both sides are squeezed toward the vertical movable block 21, and the slider 24 provided on the lower surface of the horizontal movable block 22 slides inward in the slide groove 23 opened inside the bearing seat 16. Since the L-shaped block 17 connected to the outside of the support plate 12 is clamped in the inside of the clamping groove 18 opened on the horizontal movable block 22, the opposite side of the support plate 12 is connected to the bearing frame 13, and the bearing The opposite ends of the carrier frame 13 are connected to the elastic column 14 and the spring 2 15. When the horizontal movable block 22 moves inward, the elastic column 14 and the spring 2 15 provide a certain pulling force. At the same time, the fixed sleeve rod 19 and the movable rod 20 arranged between the vertical movable block 21 and the slide groove 23 move relative to each other, and the elastic column 2 26 and the spring 3 27 arranged inside the fixed sleeve rod 19 and the movable rod 20 squeeze each other, generating an upward force on the rail 2, the vertical movable block 21, the horizontal movable block 22, the fixed sleeve rod 19, and the movable rod 20. At this time, the oblique sides of the vertical movable block 21 are tightly fitted with the oblique sides of the horizontal movable block 22, thereby transmitting the force on the rail 2 to the device body 1, and finally to the roadbed. While the rail 2 recovers its deformation upward, it drives the oblique side of the vertical movable block 21 connected to it to separate from the horizontal movable block 22. Under the reverse action of spring two 15, it assists in pushing it upward, so that the rail 2 can maintain its initial state and still have load-bearing capacity. At the same time, when the vertical movable block 21 is detached, it drives the moving rod 20 to move relatively upward in the fixed sleeve rod 19. At the same time, spring three 27 assists in pushing the moving rod 20 to move relatively upward, thereby further assisting in pushing the rail 2 to restore its initial state, thereby forming an initial mechanical balance system. At this time, the displacement of the track geometry caused by the automatic adjustment of the rail groove is small, which can minimize the impact on train operation.

[0030] The elastic support mechanism includes a spring 10, an elastic oblique rod mechanism and a horizontal guide buffer mechanism. Springs 10 are fixedly connected to both sides of the lower surface of the top plate 5. The lower end of the spring 10 is fixedly connected to the upper surface of the bottom plate 7. One end of a set of elastic oblique rod mechanisms is connected to both sides of the lower surface of the top plate 5, and the other end of the elastic oblique rod mechanism is connected to the horizontal guide buffer mechanism. The horizontal guide buffer mechanism is horizontally arranged on the upper surface of the bottom plate 7.

[0031] The elastic diagonal rod mechanism includes a connecting sleeve 33, an elastic column 4 30, a spring 5 31 and a connecting sleeve rod 34, etc. The horizontal guide buffer mechanism is composed of an elastic column 3 29, a spring 4 28, a limit plate 35, etc. The lower surface of the top plate 5 is fixedly connected to a hinge seat 6 on both sides, and the hinge seat 6 is hinged inside the connecting sleeve 33. The interior of the connecting sleeve 33 is slidably connected to the connecting sleeve rod 34. The upper surface of the bottom plate 7 is fixedly connected to the side plate 9 on both sides, and the opposite side of the side plate 9 is slidably connected to the hinge seat 2 8. The lower surface of the hinge seat 2 8 is slidably connected to the upper surface of the bottom plate 7, and the interior of the hinge seat 2 8 is hinged to the outer end of the connecting sleeve rod 34. One end of the interior is fixedly connected to an elastic column 4 30, and the outer surface of the elastic column 4 30 is sleeved with a spring 5 31. One end of the spring 5 31 is fixedly connected to the interior of the connecting sleeve 33, and the other ends of the elastic column 4 30 and the spring 5 31 are fixedly connected to the upper end of the connecting sleeve rod 34. One side of the hinge seat 2 8 is fixedly connected to the limit plate 35. Both sides of the inner lower surface of the device body 1 are fixedly connected to the fixed block 11. The limit plate 35 and the opposite side of the fixed block 11 are fixedly connected to the elastic column 3 29. The outer surface of the elastic column 3 29 is sleeved with a spring 4 28. The two ends of the spring 4 28 are respectively fixedly connected to the limit plate 35 and the opposite side of the fixed block 11. When the device body 1 When the device body 1 is bent by downward pressure, the downward pressure exerted on the top plate 5 provided inside the device body 1 acts on the top plate 5 provided therein, and the top plate 5 generates downward squeezing force. Since hinged seats 16 are provided on both sides of the lower surface of the top plate 5, the hinged seat 16 is hinged to the connecting sleeve 33, and the connecting sleeve 33 is slidably connected to the connecting sleeve rod 34. The connecting sleeve rod 34 is hinged to the hinged seat 28, and both sides of the hinged seat 28 are slidably connected to the side plates 9. At the same time, the hinged seat 28 is slidably connected to the bottom plate 7 provided on the lower surface of the side plates 9. At the same time, the connecting sleeve 33 and the connection 2 are connected by the spring column 4 and the spring 5 31. When the top plate 5 moves downward, the hinged seat 16 is driven to move downward, and the hinged seat 16 is hinged to the side plates 9. The connecting sleeve 33 and the connecting sleeve rod 34 are driven to move at an angle to both sides. The movement of the connecting sleeve rod 34 drives the hinge seat 2 8 to move to both sides. The hinge seat 2 8 slides inside the U-shaped frame formed by the side block and the bottom block, and at the same time squeezes the spring four 28 and the elastic column three 29, so that the spring four 28 and the elastic column three 29 are deformed. At the same time, the connecting sleeve 33 and the connecting sleeve rod 34 squeeze the elastic column four 30 and the spring five 31 against each other, so that the spring five 31 and the elastic column four 30 are deformed. At the same time, the spring one 10 connected between the top plate 5 and the bottom plate 7 is deformed, thereby offsetting the downward pressure of the device body 1 and avoiding the device body 1 from breaking.

[0032] Among them, notches are provided on both sides of the lower surface of the rail 2, and the rail pads 3 are movably connected inside the notches. Fixed bases 25 are fitted on both sides of the rail 2, and honeycomb holes 32 are evenly provided inside the rail pads 3. Fixing bolts 4 are movably installed on both sides of the fixed base 25. The lower surface of the fixed base 25 fits with the upper surface of the fixing bolts 4. When the train passes over the rail 2, an impact will be generated and act on the rail pads 3 set on the lower surface of the rail 2. The honeycomb holes 32 opened on the rail pads 3 disperse the impact, which can achieve a certain vibration reduction and noise reduction effect.

[0033] Working principle: when in use, first, when the device body 1 is impacted by the wheel-rail, the impact on the device body 1 acts on the top plate 5 set inside it, and the top plate 5 generates an extrusion force downward. Since the hinge seat 1 6 is set on both sides of the lower surface of the top plate 5, the hinge seat 1 6 is hinged to the connecting sleeve 33, and the connecting sleeve 33 and the connecting sleeve rod 34 are slidingly connected. The connecting sleeve rod 34 is hinged to the hinge seat 2 8, and the two sides of the hinge seat 2 8 are slidingly connected to the side plates 9. At the same time, the hinge seat 2 8 is slidingly connected to the bottom plate 7 set on the lower surface of the side plate 9. At the same time, the connecting sleeve 33 and the connection 2 are connected by the spring column 4 and the spring 5 31. When the top plate 5 moves downward, it drives the hinge seat 1 6 to move downward, and the hinge seat 1 6 drives The connecting sleeve 33 and the connecting sleeve rod 34 move at an angle to both sides, and the movement of the connecting sleeve rod 34 drives the hinge seat 2 8 to move to both sides. The hinge seat 2 8 slides inside the U-shaped frame formed by the side block and the bottom block, and at the same time squeezes the spring 4 28 and the elastic column 3 29, so that the spring 4 28 and the elastic column 3 29 are deformed. At the same time, the connecting sleeve 33 and the connecting sleeve rod 34 squeeze the elastic column 4 30 and the spring 5 31 against each other, so that the spring 5 31 and the elastic column 4 30 are deformed. At the same time, the spring 10 connected between the top plate 5 and the bottom plate 7 is deformed, thereby offsetting the impact load on the device body 1, thereby having a better buffering effect on the wheel-rail impact and providing a certain elasticity for the track as a whole.

[0034] When a train passes over the rail 2, a downward force is generated and transmitted to the roadbed by the rail 2, the vertical movable block 21, the horizontal movable block 22, the fixed sleeve rod 19, the movable rod 20 and the device body 1. At this time, the oblique sides of the vertical movable block 21 fit tightly with the oblique sides of the horizontal movable block 22, thereby transmitting the force exerted on the rail 2 to the device body 1 and finally to the roadbed. If the track bed or roadbed sinks, the rail 2 will produce elastic bending deformation downward along with the device body 1, but the rail 2 is constrained by the long rail bar, which will generate a large upward elastic force. When the rail 2 is in its original position, it will drive the oblique side of the vertical movable block 21 connected to it to separate from the horizontal movable block 22. Under the reverse force of the spring 2 15, it will assist in pushing it to maintain its original absolute position, so that the rail 2 can maintain its initial state on a macro scale. At the same time, when the vertical movable block 21 is separated, it drives the moving rod 20 to move upward in the fixed sleeve rod 19. At the same time, the spring 3 27 assists in pushing the moving rod 20 upward, thereby further assisting in pushing the rail 2 to restore its initial state, thereby forming an initial mechanical balance system. When the train wheels pass again, if the track bed does not sink, the various parts will not move, the overall height of the device remains unchanged, and the downward force transmitted does not change the relative position of the device body 1 and the track bed; if the track bed sinks, the above-mentioned adjustment process and the setting of this structure are repeated again.

[0035] When a train passes over the rail 2, an impact is generated, and the impact acts on the rail pad 3 provided on the lower surface of the rail 2. The honeycomb holes 32 provided on the rail pad 3 disperse the impact. At the same time, the rail pad 3 is not in complete contact with the ground, so the impact is blocked, which can achieve a certain vibration reduction and noise reduction effect.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
