Abstract
Description
Technical Field
[0001] This utility model belongs to the field of turnout sleeper laying technology, and more specifically, it relates to a turnout sleeper positioning device. Background Technology
[0002] Turnout sleepers are special sleepers used on railway turnouts, mainly at the turnout traction point. They allow the turnout electrical switching rods to be placed inside the sleeper, which is beneficial for large-scale maintenance operations. When the quality of a turnout sleeper deteriorates due to long-term use, it needs to be replaced in a timely manner. When replacing a single turnout sleeper in a railway turnout area, maintaining the precise spatial position of adjacent turnout sleepers is crucial.
[0003] Existing methods primarily use lateral support devices to limit the lateral displacement of turnout sleepers. However, these methods lack effective constraints on vertical positional changes. During construction, due to track bed disturbances, rail lifting, and the placement of new turnout sleepers, adjacent sleepers are prone to unexpected subsidence or uplift, causing track level to exceed limits, disrupting the lateral levelness of the rails, and affecting train stability. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a turnout sleeper positioning device is provided, including a U-shaped seat, two clamping members, and an upper clamping member. The U-shaped seat is disposed between two adjacent turnout sleepers. The U-shaped seat has two upwardly bent portions, which correspond one-to-one with the opposite side walls of the two turnout sleepers. The upper edge of the bent portion is provided with a lower pressure plate that extends horizontally outward and abuts against the top surface of the turnout sleeper. The two clamping members are disposed inside the U-shaped seat and correspond one-to-one with the two bent portions. The clamping members pass through the bent portions and are threadedly connected to the bent portions to clamp the side walls of the turnout sleepers. The upper clamping member passes through the U-shaped seat in the vertical direction and has a push rod that extends horizontally to the bottom of the two turnout sleepers. The upper clamping member can drive the push rod to move upward and cooperate with the lower pressure plate to clamp the turnout sleeper.
[0006] In one possible implementation, the upper support includes a screw and an adjusting nut. The screw passes through the U-shaped seat in the vertical direction, and the push rod is connected to the lower end of the screw. The adjusting nut is threaded onto the upper outer periphery of the screw and located inside the U-shaped seat, for abutting against the inner bottom wall of the U-shaped seat.
[0007] In some embodiments, the U-shaped seat is provided with a limiting member that extends through the U-shaped seat and the top rod in the vertical direction, which is used to limit the relative rotation of the top rod and the U-shaped seat, and the adjusting nut can rotate to drive the screw to move upward.
[0008] In some embodiments, the limiting member includes a limiting rod and a limiting plate. The limiting rod passes through the U-shaped seat and the top rod in the vertical direction. The limiting plate is connected to the upper end of the limiting rod and is used to contact and cooperate with the inner bottom wall of the U-shaped seat.
[0009] In some embodiments, the limiting plate has a clearance hole running through it in the vertical direction, the adjusting nut is located in the clearance hole, and there are two limiting rods, which are located on both sides of the screw respectively.
[0010] In some embodiments, a U-shaped reinforcing member is provided below the limiting member, and the two ends of the U-shaped reinforcing member are respectively provided with receiving grooves for accommodating the lower parts of the two limiting rods. The inner bottom wall of the receiving groove is provided with a magnet for adsorbing the limiting rods.
[0011] In some embodiments, a lifting ring is rotatably connected to the outer peripheral edge of the limiting plate, and the lifting ring is capable of vertical swinging.
[0012] In some embodiments, a gasket is provided between the adjusting nut and the U-shaped seat.
[0013] In some embodiments, a reinforcing nut is threaded onto the upper outer circumference of the screw, located above the adjusting nut, for pressing the adjusting nut downwards.
[0014] In one possible implementation, a fixing nut is connected to the outer wall of the bent portion, and the fixing nut is threaded onto the outer periphery of the clamping member.
[0015] Compared with the prior art, the turnout sleeper positioning device provided in this embodiment first removes the four turnout sleeper positioning devices on this turnout sleeper. There are two turnout sleeper positioning devices on each of the two turnout sleepers adjacent to the turnout sleeper that needs to be replaced. The turnout sleeper is clamped and fixed by the lower pressure plate and the top rod, and the limit of the clamping and tightening parts restricts the horizontal and vertical displacement of the turnout sleeper, so as to ensure its stable position. This avoids the situation that replacing one turnout sleeper will affect the position of the adjacent turnout sleepers, and ensures the lateral levelness of the rail and the smoothness and stability of the train.

[0021] Turnout sleepers are special sleepers used on railway turnouts. Several sleepers are spaced along the rails, with their extension direction perpendicular to the rails. Each sleeper has an H-beam at its bottom, and wooden blocks are placed between the H-beam and the sleeper. These wooden blocks are spaced along the length of the sleeper, with gaps between adjacent blocks. Turnout sleepers are mainly used at the turnout traction point, allowing the turnout electrical switching rods to be placed inside, which facilitates maintenance work. When the quality of a sleeper deteriorates due to long-term use, it needs to be replaced promptly. Maintaining the precise spatial position of adjacent sleepers is crucial when replacing a single sleeper in a railway turnout area.
[0022] Existing methods primarily use lateral support devices to limit the lateral displacement of turnout sleepers. However, these methods lack effective constraints on vertical positional changes. During construction, due to track bed disturbances, rail lifting, and the placement of new turnout sleepers, adjacent sleepers are prone to unexpected subsidence or uplift, causing track level to exceed limits, disrupting the lateral levelness of the rails, and affecting train stability.
[0023] Please see Figures 1 to 5 The present invention provides a switch rest positioning device. The switch rest positioning device includes a U-shaped seat 10, two clamping members 20, and an upper clamping member 30. The U-shaped seat 10 is disposed between two adjacent switch rests 1. The U-shaped seat 10 has two upwardly bent portions 11, each corresponding to one of the opposite side walls of the two switch rests 1. The upper edge of each bent portion 11 has a lower pressure plate 12 extending horizontally outward and used to abut against the top surface of the switch rest 1. The two clamping members 20 are disposed within the U-shaped seat 10 and correspond to the two bent portions 11. The clamping members 20 penetrate the bent portions 11 and are threadedly connected to them, used to clamp the side walls of the switch rest 1. The upper clamping member 30 penetrates the U-shaped seat 10 in a vertical direction and has a push rod 31 extending horizontally to the bottom of the two switch rests 1. The upper clamping member 30 can drive the push rod 31 upward and cooperate with the lower pressure plate 12 to clamp the switch rest 1.
[0024] Furthermore, the clamping element 20 is a bolt.
[0025] Furthermore, a turnout positioning device is provided between every two adjacent turnout sleepers 1.
[0026] Furthermore, two turnout sleeper positioning devices are provided at intervals along the length of turnout sleeper 1, and are respectively located near both ends of turnout sleeper 1.
[0027] Furthermore, each turnout sleeper 1 has an H-beam 2 at its bottom, and a wooden block 3 is placed between the H-beam 2 and the turnout sleeper 1. Several wooden blocks 3 are spaced apart along the length of the turnout sleeper 1, and there is a gap between two adjacent wooden blocks 3. The top rod 31 is inserted into the bottom of the turnout sleeper 1, that is, it is located in the gap between two adjacent wooden blocks 3.
[0028] This application provides a turnout sleeper positioning device. In actual use, the U-shaped seat 10 spans two turnout sleepers 1, and together with the lower pressure plate 12 (vertical downward pressure), the clamping member 20 (horizontal lateral pressure), and the upper lifting member 30 (vertical upward lifting force), it forms a constraint, completely restricting the displacement freedom of the turnout sleeper 1. Compared with traditional single-point fixing devices, it eliminates the risks of longitudinal sliding, lateral displacement, and vertical lifting of the turnout sleeper 1 during construction, and is especially suitable for the stringent requirements of high-speed railways for track smoothness.
[0029] The lower pressure plate 12 of the bent part 11 contacts the top surface of the turnout sleeper 1 to disperse local pressure; the tightening part 20 achieves stepless adjustment through threaded advancement to adapt to turnout sleepers 1 of different widths; the top rod 31 of the upper lifting part 30 extends into the bottom of the turnout sleeper 1 to compensate for the difference in installation surface height caused by uneven settlement of the track bed and improve the versatility of the device.
[0030] Furthermore, the turnout sleeper positioning device can ensure that all turnout sleepers 1 are connected as a whole during normal use, preventing any turnout sleeper 1 from shifting position in a long-term vibration environment and ensuring its stability.
[0031] When it is necessary to replace a turnout sleeper 1, first remove the four turnout sleeper positioning devices on this turnout sleeper 1. There are two turnout sleeper positioning devices on each of the two turnout sleepers 1 adjacent to the turnout sleeper 1 that needs to be replaced. The lower pressure plate 12 and the top rod 31 clamp and fix the turnout sleeper 1 in conjunction with the limiting of the top clamping member 20 to restrict the horizontal and vertical displacement of the turnout sleeper 1, so as to ensure its stable position and avoid the situation that replacing a turnout sleeper 1 will affect the position of the adjacent turnout sleepers 1, thus ensuring the lateral levelness of the rail and the smoothness and stability of the train.
[0032] Before replacing a switch sleeper 1, mark (draw lines or predict the distance between this switch sleeper 1 and the adjacent switch sleeper 1) the position of this switch sleeper 1 to facilitate the alignment and installation of the new switch sleeper 1. After replacing a switch sleeper 1, install the corresponding switch sleeper positioning devices on both sides of this switch sleeper 1. First, adjust the corresponding clamping parts 20 to push the switch sleeper 1 for a slight position adjustment. After the adjustment is completed, make the four clamping parts 20 clamp the two sides of this switch sleeper 1. Then, adjust the upper clamping part 30 to clamp and fix the switch sleeper 1 through the lower pressure plate 12 and the top rod 31 to maintain its positional stability.
[0033] Compared with the prior art, the turnout sleeper positioning device provided in this embodiment first removes the four turnout sleeper positioning devices on the turnout sleeper 1. There are two turnout sleeper positioning devices on each of the two turnout sleepers 1 adjacent to the turnout sleeper 1 that needs to be replaced. The turnout sleeper 1 is clamped and fixed by the lower pressure plate 12 and the top rod 31, and the clamping member 20 limits the horizontal and vertical displacement of the turnout sleeper 1, so as to ensure its stable position. This avoids the situation that replacing one turnout sleeper 1 will affect the position of the adjacent turnout sleepers 1, and ensures the lateral levelness of the rail and the smoothness and stability of the train.
[0034] In one possible implementation, the aforementioned upper top member 30 adopts as follows: Figures 1 to 4 The structure shown is described in the following document. Figures 1 to 4 The upper top part 30 includes a screw 32 and an adjusting nut 33. The screw 32 passes through the U-shaped seat 10 in the vertical direction, and the top rod 31 is connected to the lower end of the screw 32. The adjusting nut 33 is threaded on the upper outer periphery of the screw 32 and located inside the U-shaped seat 10, and is used to abut against the inner bottom wall of the U-shaped seat 10.
[0035] Specifically, the screw 32 and adjusting nut 33 mechanism provides high fine-tuning capability. By rotating the adjusting nut 33, the screw 32 is driven to rise and fall, precisely controlling the lifting force of the top rod 31 on the fork bolster 1, ensuring the clamping and fixing of the fork bolster 1; the self-locking characteristic of the threaded pair prevents the lifting force from attenuating under vibration environment, ensuring long-term positioning stability.
[0036] The adjusting nut 33 directly abuts against the inner bottom wall of the U-shaped seat 10, which evenly transmits the lifting reaction force to the overall structure of the U-shaped seat 10, avoiding deformation caused by local stress concentration and extending the service life of the device.
[0037] In use, adjust the top rod 31 so that its two ends are inserted into the bottom of the two adjacent turnout sleepers 1 respectively. Hold the top rod 31 to restrict its rotation, and rotate the adjusting nut 33 so that it abuts against the inner bottom wall of the U-shaped seat 10 (the lower pressure plate 12 abuts against the top wall of the turnout sleeper 1). At the same time, the top rod 31 abuts against the bottom wall of the turnout sleeper 1 to achieve quick clamping and fixing of the turnout sleeper 1.
[0038] In some embodiments, see Figures 1 to 3 The U-shaped seat 10 is provided with a limiting member 40 that runs through the U-shaped seat 10 and the top rod 31 in the vertical direction, which is used to limit the relative rotation of the top rod 31 and the U-shaped seat 10. The adjusting nut 33 can rotate to drive the screw 32 to move upward.
[0039] Specifically, the push rod 31 and the limiting member 40 are in sliding engagement. The limiting member 40 forcibly restricts the circumferential freedom of the push rod 31 and the U-shaped seat 10, eliminating the risk of the push rod 31 rotating with it when the adjusting nut 33 rotates. Rotating the adjusting nut 33 can directly drive the screw 32 to rise, without the need for additional manual fixing of the push rod 31, simplifying the construction steps and reducing the intensity of manual labor.
[0040] In some embodiments, see Figures 1 to 3 The limiting member 40 includes a limiting rod 41 and a limiting plate 42. The limiting rod 41 passes through the U-shaped seat 10 and the top rod 31 in the vertical direction. The limiting plate 42 is connected to the upper end of the limiting rod 41 and is used to contact and cooperate with the inner bottom wall of the U-shaped seat 10.
[0041] Specifically, the limiting plate 42 is used to restrict the limiting rod 41 from moving downward and disengaging from the top rod 31. The limiting rod 41 passes through the U-shaped seat 10 and forms a two-point constraint with the top rod 31 to resist lateral load.
[0042] The limit rod 41 can be pulled upwards and disassembled and replaced independently, avoiding the scrapping of the entire device due to partial damage and reducing maintenance costs.
[0043] In use, the push rod 31 is pressed against the bottom wall of the fork bolster 1, and the adjusting nut 33 is pre-tightened. After the adjusting nut 33 is pressed against the inner bottom wall of the U-shaped seat 10, the push rod 31 is loosened. The adjusting nut 33 is rotated with force using an external tool. Under the limit of the limit rod 41, the push rod 31 moves upward and presses against the bottom wall of the fork bolster 1, and the lower pressure plate 12 moves downward and presses against the top wall of the fork bolster 1.
[0044] In some embodiments, see Figures 1 to 3 The limiting plate 42 has a clearance hole 421 extending through it in the vertical direction. The adjusting nut 33 is located inside the clearance hole 421. There are two limiting rods 41, which are located on both sides of the screw 32 respectively.
[0045] Specifically, the clearance hole 421 allows the adjusting nut 33 to be nested inside the limiting plate 42, and the inner diameter of the clearance hole 421 is much larger than the maximum outer diameter of the adjusting nut 33, that is, the adjusting nut 33 and the limiting plate 42 do not interfere with each other, thus solving the interference problem caused by the narrow internal cavity of the U-shaped seat 10; the double limiting rods 41 are symmetrically distributed on both sides of the screw 32 to form a force couple balance, which counteracts the bending moment caused by the eccentric load and prevents the screw 32 from bending.
[0046] In some embodiments, see Figures 1 to 3 and Figure 5 Below the limiting member 40 is a U-shaped reinforcing member 50. At both ends of the U-shaped reinforcing member 50 are receiving grooves 51 for accommodating the lower parts of the two limiting rods 41. On the inner bottom wall of the receiving groove 51 are magnets 52 for adsorbing the limiting rods 41.
[0047] Specifically, the U-shaped reinforcing member 50 is a columnar rod bent into a U-shape, which wraps around the lower part of the two limiting rods 41, making the limiting member 40 and the U-shaped reinforcing member 50 a whole, forming a local stiffness enhancement area, and preventing the lower part of the two limiting rods 41 from bending due to insufficient strength; the magnet 52 is attracted to the bottom of the limiting rod 41, which not only facilitates installation, but also prevents the limiting rod 41 from falling out of the receiving groove 51.
[0048] Magnetic fastening replaces bolt connections, enabling tool-free assembly and disassembly of the U-shaped reinforcement 50.
[0049] In some embodiments, see Figure 2 and Figure 3 The outer periphery of the limiting plate 42 is rotatably connected to a lifting ring 43, which can swing vertically.
[0050] Specifically, the lifting ring 43 allows the operator to apply force while standing upright to lift the limiting plate 42 (traditional designs require squatting to remove it), reducing labor intensity and facilitating the removal of the limiting component 40 from the U-shaped seat 10.
[0051] In some embodiments, see Figure 4 A washer 60 is provided between the adjusting nut 33 and the U-shaped seat 10.
[0052] Specifically, the washer 60 is placed between the adjusting nut 33 and the U-shaped seat 10 to reduce the frictional torque when the thread rotates, making the adjustment easier.
[0053] In some embodiments, see Figures 2 to 4 The upper outer circumference of the screw 32 is threaded with a reinforcing nut 70 located above the adjusting nut 33, which is used to tighten the adjusting nut 33 downwards.
[0054] Specifically, the reinforcing nut 70 tightens the adjusting nut 33 downwards, creating mechanical redundancy to resist vibration-induced loosening. Under high-frequency vibration conditions of the train, the double-nut structure can reduce the possibility of the adjusting nut 33 loosening due to vibration, significantly improving the reliability of the device.
[0055] In one possible implementation, the aforementioned bent portion 11 adopts the following... Figures 2 to 4 The structure shown is described in the following document. Figures 2 to 4 A fixing nut 80 is connected to the outer wall of the bent part 11, and the fixing nut 80 is threaded onto the outer periphery of the tightening member 20.
[0056] Specifically, the fixing nut 80 is welded externally to the outside of the bend 11, so that the threaded pair of the clamping member 20 is kept away from the ballast dust.
[0057] Furthermore, the setting of the fixed nut 80 avoids directly machining threads on the bent part 11 during the processing, reducing the processing difficulty.
[0058] It should be noted that the limiting component 40 and the U-shaped reinforcing component 50 are reusable components. In actual use, after installing one turnout sleeper positioning device, the limiting component 40 and the U-shaped reinforcing component 50 can be used for the installation of the next turnout sleeper positioning device. After all the turnout sleeper positioning devices are installed, the limiting component 40 and the U-shaped reinforcing component 50 can be removed and stored. When disassembling the turnout sleeper positioning device, the limiting component 40 and the U-shaped reinforcing component 50 are installed again. That is, multiple turnout sleeper positioning devices share a set of limiting components 40 and U-shaped reinforcing components 50. Figure 1 The two turnout sleeper positioning devices shown are, in one state where the limit member 40 and U-shaped reinforcement 50 have been used, and in the other state where the limit member 40 and U-shaped reinforcement 50 are being used.
[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
