Description

Technical Field

[0001] This utility model relates to the field of railway track maintenance technology, specifically to a track gauge adjustment tool. Background Technology

[0002] Adjusting track gauge is a common track operation in the engineering section. Under normal circumstances, in order to ensure that the track geometry meets the standards, it is necessary to adjust the track gauge at the locations where the gauge exceeds the standard.

[0003] The standard track gauge is 1435 mm. The existing track gauge adjustment method involves slightly loosening the bolts, moving the rail to change the track gauge, measuring the standard track gauge with a track gauge ruler, maintaining the amount of movement, adjusting the nylon seat, fasteners, etc., and then using a T-shaped bevel to tighten the front and rear bolts and fasteners at that point to lock the rail, thereby achieving the purpose of adjusting the track gauge.

[0004] However, in the above process, moving the rail usually requires using a crowbar to hold the bolts and move the rail. But the crowbar is heavy, and if it slips, the operator is at risk of being bumped or injured. Moreover, after moving the rail, the operator needs to exert continuous force to keep the gauge unchanged and then lock the rail. If the operator relaxes even slightly during this process, the gauge will change, which is not conducive to precise gauge adjustment.

[0005] Therefore, there is an urgent need for a gauge adjustment tool that can both improve gauge accuracy and eliminate safety risks. Utility Model Content

[0006] The purpose of this utility model is to provide a track gauge adjustment tool to overcome the problems existing in the prior art. This utility model can significantly improve the accuracy of track gauge and also eliminate the safety risks when using a crowbar to pry the rails.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a track gauge adjustment tool, including a support rod device, a clamping device connected to the support rod device, and a sleeve connected to the support rod device. The top of the sleeve is provided with a locking block for squeezing the rail and adjusting the rail to the standard track gauge. In some embodiments, the support rod device includes a first main rod, a second main rod connected to the middle of the first main rod, and the end of the second main rod away from the first main rod connected to a sleeve; In some embodiments, the angle between the first main rod and the second main rod is 90°; In some embodiments, the first main rod and the second main rod are made of metal; In some embodiments, the length of the first main rod is less than the length of the second main rod; In some embodiments, the sleeve is made of metal; In some embodiments, the sleeve is hexagonal in shape; In some embodiments, the interior of the sleeve is divided by a horizontal diagonal line, with half of the space being sealed off and the size of the other half of the space being adapted to the size of the bolt thread of the rail; In some embodiments, the shape of the card block is semi-circular; In some embodiments, the card block is made of metal.

[0008] The above technical solution has the following advantages or beneficial effects: This utility model provides a track gauge adjustment tool. First, by inserting the sleeve with the unsealed end aligned with the sleeper bolt threaded rod and ensuring the locking block is tangential to the bottom of the rail, the rail can be moved by forcefully twisting the first and second main rods. The single-sided adjustment range is 0–10 mm, and the overall adjustable track gauge range is -10 mm to 10 mm, fully meeting daily track gauge adjustment needs. Second, this utility model's track gauge adjustment tool is simple to operate, labor-saving, and efficient, effectively avoiding the safety risks of traditional pry bars slipping or slipping out of the hand. When adjusting to the standard track gauge, the sleeve is tightly locked between the rail and the bolt threaded rod, providing high stability and preventing slippage, reliably locking the track gauge and significantly improving adjustment accuracy and work quality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: In existing technologies, adjusting railway track gauge typically involves loosening bolts with a pry bar and then manually moving the rails. This process requires continuous external force to maintain the rail position, posing a risk of tool slippage and potential accidents. Furthermore, maintaining track gauge stability manually is difficult to control precisely, and operational errors can easily lead to deviations in the adjusted gauge.

[0017] To address these issues, researchers investigated the safety hazards and precision deficiencies of traditional tools. Analysis revealed that the lack of a reliable fixing mechanism in existing crowbars was the root cause of slippage and unstable force application. Therefore, the design approach shifted to developing tools with rigid support structures, using mechanical devices to replace manual force application and create a stable clamping effect during rail adjustment.

[0018] Therefore, this application proposes a track gauge adjustment tool including a support rod device and a clamping device, wherein the support rod device is connected to the clamping device for pressing the rail to achieve track gauge adjustment.

[0019] Figure 1 This is a schematic diagram of the structure of a track gauge adjustment tool according to some embodiments of this specification. Figure 2 This is a top view of a track gauge adjustment tool according to some embodiments of this specification. The track gauge adjustment tool includes a support rod device and a clamping device. The support rod device is connected to the clamping device and is used to press the rail and adjust the rail to the standard track gauge. In some embodiments, the support rod device refers to a rod-shaped structure that provides rigid support, specifically a combination of main rods made of metal, used to transmit mechanical forces. The support rod device includes a first main rod 1 and a second main rod 2. The first main rod 1 refers to the main structure constituting the support rod device, and its length can be adjusted according to actual operational needs. The second main rod 2 refers to an auxiliary support structure that forms a connection with the first main rod 1. Specifically, it can be fixed to the middle of the first main rod 1 by welding or bolting, used to provide lateral support force and distribute the force. In some embodiments, the angle between the first main rod 1 and the second main rod 2 is 90°. A 90° angle means that the first main rod 1 and the second main rod 2 form a right-angle connection. This can be achieved by welding, bolting, or integral molding, which can enhance the overall rigidity of the support rod device and prevent deformation during force application. The first main rod 1 and the second main rod 2 form a support frame through a right-angle connection. During operation, the operator applies force to the support rod device, causing the clamping device to exert a squeezing effect on the rail. Due to the right-angle connection structure of the two main rods, the support rod device can form a stable force transmission path when subjected to force, avoiding deviation in the force direction due to angular deviation, thereby ensuring the accuracy of the rail movement trajectory. In some embodiments, the first main rod 1 and the second main rod 2 are made of metal, specifically steel, aluminum alloy or titanium alloy. The metal material can withstand the large mechanical stress generated during the gauge adjustment process. In some embodiments, the first main rod 1 and the second main rod 2 are cylindrical metal rods; In some embodiments, the length of the first main rod 1 may be 600 mm, and the diameter of the first main rod 1 may be 30 mm; In some embodiments, the length of the second main rod 2 may be 750 mm, and the diameter of the second main rod 2 may be 30 mm; Specifically, the first main rod 1, as the main load-bearing component, forms a cross structure with the second main rod 2 connected in the middle, enabling the support rod device to apply longitudinal and lateral forces simultaneously during operation. During the gauge adjustment process, the connection point between the second main rod 2 and the first main rod 1 serves as a fulcrum, transmitting the operating force to the clamping device through the lever principle, thereby stably squeezing the rail. This structure avoids the risk of deformation caused by uneven force on a single rod, and at the same time, the synergistic effect of the two rods enhances the overall rigidity, ensuring that the rail does not shift during adjustment. Compared with existing technologies, existing crowbars rely on a single rod structure to move the rail, which is prone to slippage or deformation due to concentrated force. However, this solution, through the cross connection design of the first main rod 1 and the second main rod 2, forms a stable support frame, which not only reduces the risk of slippage during operation, but also reduces the need for continuous force application by the operator through the synergistic effect of the two rods. Through the above technical solution, this utility model can improve the stability of the track gauge adjustment tool, avoid safety hazards caused by tool slippage, and achieve a more uniform force distribution through the double rod structure, ensuring that the rail remains in a fixed position during the adjustment process, thereby improving the accuracy of track gauge adjustment and work efficiency.

[0020] Figure 3 This is a left view of a gauge adjustment tool according to some embodiments of this specification. The gauge adjustment tool includes a support rod device and a clamping device. The support rod device is connected to the clamping device and is used to press the rail and adjust the rail to a standard gauge. In some embodiments, the clamping device includes a sleeve 3, which is connected to the end of the second main rod 2 away from the first main rod 1, and a locking block 4 is provided on the top of the sleeve 3; the clamping device refers to the clamping component that contacts the rail and is used to firmly clamp the rail to prevent displacement; the sleeve 3 refers to the tubular component that wraps around the bolt thread rod of the rail and is used to form a geometric fit with the bolt; the locking block 4 refers to the limiting component provided on the top of the sleeve 3 and is used to prevent the sleeve 3 from separating from the bolt. In some embodiments, the sleeve 3 is made of metal, which can be formed by forging or casting. Its function is to utilize the hardness and wear resistance of metal to enhance the wear resistance of the sleeve 3 when in contact with the rail, and extend the service life of the tool. After the sleeve 3 is made of metal, it can withstand greater compressive force during the adjustment of the gauge, avoiding deformation or damage caused by insufficient material strength. When the rail is compressed to the standard gauge, the metal sleeve 3 transmits the force through the matching structure with the rail bolt screw, ensuring the accuracy and reliability of the adjustment action, while reducing the risk of slippage caused by tool deformation. In some embodiments, the sleeve 3 is hexagonal in shape, which means that the sleeve 3 has a structure with six symmetrical interior angles. Specifically, it can be achieved by using a hexagonal hole structure. The six interior angles form a uniformly distributed contact surface. By increasing the contact area between the inner wall of the sleeve 3 and the bolt head, the sleeve 3 enhances the wrapping of the bolt, thereby preventing slippage when torque is applied. This utility model provides sufficient structural strength through metal material and hexagonal shape. In some embodiments, the length of the sleeve 3 may be 80 mm, and the wall thickness of the sleeve 3 may be 8 mm; In some embodiments, the interior of the sleeve 3 is divided by a horizontal diagonal, with one half of the space being sealed off and the other half being sized to match the bolt rod of the rail. The horizontal diagonal divides the interior of the sleeve 3 into two symmetrical regions along its cross-section. This can be achieved by creating a partition structure on the inner wall of the sleeve 3 or by casting the dividing region. This division clearly defines the spatial distribution of the sealed and fitted regions, allowing the sleeve 3 to be precisely fitted onto the rail bolt rod and limiting lateral displacement. The sealing means that a portion of the interior space of the sleeve 3 is completely filled or sealed by solid material. This can be achieved by welding a metal plate or casting a one-piece sealed structure. This design prevents the tool from shifting or sliding during use. The size matching means that the internal shape of the unsealed area of ​​the sleeve 3 matches the shape of the rail bolt rod. This can be achieved by using an internal hexagonal, polygonal, or threaded cavity structure. This matching ensures that the sleeve 3 and the bolt rod fit tightly together to transmit torque. Specifically, after the inside of the sleeve 3 is divided into two areas by a horizontal diagonal, the blocking area can restrict the displacement of the sleeve 3 in the non-working direction during operation, while the fitting area precisely matches the bolt screw. When the tool applies force, the blocking area provides rigid support, and the fitting area transmits torque to the bolt screw through shape matching, thereby preventing relative slippage between the sleeve 3 and the bolt during the adjustment of the track gauge. In some embodiments, the interior space of the sleeve 3 is divided into two isosceles trapezoids by a horizontal diagonal. The length of the diagonal can be 25 mm, the length of the upper base of the isosceles trapezoid can be 25 mm, and the length of the lower base can be 50 mm. In some embodiments, the shape of the locking block 4 is semi-circular, the long side of the locking block 4 is connected to the sleeve 3, and the locking block 4 fits the surface of the rail with a semi-circular structure, forming a stable contact surface when the rail is squeezed, thus preventing the tool from slipping off. In some embodiments, the locking block 4 is made of metal. The locking block 4 refers to the component fixed to the top of the sleeve 3, which is used to contact the rail and transmit the compressive force. Specifically, it can be made of stainless steel or alloy steel. The metal material can withstand the high load during the extrusion process and avoid deformation or breakage due to insufficient material strength. The metal material refers to a material with high hardness, wear resistance and impact resistance. Specifically, it can be processed by forging or casting. The metal locking block 4 can maintain shape stability for a long time and reduce the risk of contact surface failure due to wear. Specifically, when the locking block 4 is made of metal, during the gauge adjustment process, when the sleeve 3 is engaged with the bolt screw of the rail, the locking block 4 forms a stable contact with the rail surface through its semi-circular structure. The compressive strength of the metal material ensures that the compressive force is evenly transmitted to the rail, avoiding slippage or loosening caused by material deformation. When locking the rail, the rigid support of the metal locking block 4 can reduce the need for continuous force application by the operator, thereby reducing adjustment errors caused by fatigue. In some embodiments, the thickness of the card block 4 may be 25 mm, and the radius of the card block 4 may be 30 mm; Specifically, the support rod device forms a stable force transmission path through rigid connection. The sleeve 3 in the clamping device is sleeved on the bolt thread of the rail to form a geometric constraint. The locking block 4 cooperates with the sleeve 3 to limit axial displacement. During operation, the support rod device applies force to cause the rail to move laterally. The cooperation between the sleeve 3 and the bolt thread ensures that the direction of force application is controllable. The locking block 4 prevents the sleeve 3 from disengaging from the bolt thread during the application of force. The structure of this utility model ensures that the rail is always in a controlled state during the adjustment process without the need for continuous manual force application. Compared with existing technologies, this solution eliminates the safety hazard of pry bar slippage by combining rigid support structure and geometric constraint device. The precise cooperation between sleeve 3 and bolt screw replaces the temporary locking method of pry bar. The limiting design of locking block 4 eliminates the need for manual clamping during the force application process, thereby achieving a dual improvement in the stability of force application direction and clamping reliability. Through the above technical solution, this utility model effectively solves the technical problems of high risk of slippage of traditional tools and unstable manual force application. The clamping device and the rail bolt screw form a reliable geometric constraint, and the support rod device provides a stable mechanical force transmission path, so that the track gauge adjustment process does not require continuous manual intervention, which not only ensures the safety of operation, but also improves the precision control capability of track gauge adjustment.

[0021] The structure and working principle of this utility model will be further explained below: The purpose of this utility model is to provide a track gauge adjustment tool. When using this device, the unsealed half of the inner sleeve 3 of the tool is aligned with the sleeper bolt thread and inserted. At this time, the tool's locking block 4 is tangent to the bottom of the rail. By forcefully twisting the first main rod 1 and the second main rod 2 of the tool, the rail is squeezed and moved. The moving distance is in the range of 0-10 mm. The track gauge adjustment range on both the inner and outer sides is -10 mm to 10 mm, which can fully meet the needs of daily adjustment of rail gap size.

[0022] This utility model of track gauge adjustment tool simplifies and facilitates track gap adjustment, improves work efficiency, and avoids the risks of slipping out of the hand when using a crowbar or slipping when prying the fulcrum. When the first main rod 1 and the second main rod 2 are twisted forcefully to drive the sleeve 3 and the locking block 4 to press the rail to the standard track gauge, the sleeve 3 is locked between the rail and the bolt screw, making it difficult to slip out. At this time, the track gauge can be stably locked, and the accuracy of track gauge adjustment is greatly improved, significantly improving work efficiency and quality. It can also eliminate the safety risks when using a crowbar to pry the rail.

[0023] This utility model track gauge adjustment tool has a simple structure, is lightweight and convenient to use, saves time and effort, and is low in cost. It changes the way track gap adjustment is performed, improves work efficiency, and eliminates the original work risks. It can be widely used by track maintenance personnel and track maintenance workers.

[0024] This utility model is made from recycled materials, which saves costs and has a simple structure. It can replace the crowbar used in the original operation, reducing the number of people working to two. Compared with the existing technology, it improves work efficiency and avoids the risk of slipping when using a crowbar or when the fulcrum is pried off. The accuracy of adjusting the track gauge is greatly improved.
