Description

Technical Field

[0001] This utility model relates to the field of track erection technology; more specifically, it relates to an auxiliary positioning device for track erection. Background Technology

[0002] Track erection is a complex and crucial engineering operation. First, precise measurement and planning are required to determine parameters such as track location, gradient, and spacing. Next, a stable supporting structure, such as bridge piers, abutments, or roadbed, is constructed. Then, track sleepers are laid on the supporting structure according to the designed spacing, and the rails are precisely installed onto the sleepers and securely connected with fasteners. Finally, track testing and inspection are conducted to ensure that the track flatness, gauge, and other specifications meet standards, guaranteeing the safe and stable operation of trains.

[0003] Track erection auxiliary positioning device is a specialized tool for improving construction accuracy. This device typically consists of a high-precision measuring instrument, an adjustable positioning bracket, and an intelligent calibration system, enabling rapid determination of the track centerline, gauge, and elevation. Through real-time monitoring using laser rangefinders and electronic levels, it assists workers in precisely adjusting the positions of sleepers and rails, ensuring that track geometry meets design requirements. The device is structurally robust, easy to operate, effectively reduces human error, and improves erection efficiency and track laying quality. It is widely used in railway, subway, and other track engineering construction.

[0004] Currently, existing positioning devices often suffer from several drawbacks. Since most existing tracks are pre-assembled and transported to the construction site for installation, positioning is crucial to prevent misalignment. However, most existing devices lack height adjustment capabilities, making it difficult to connect tracks with significant height differences, thus reducing the device's practicality. Furthermore, the lack of angle adjustment means the top of the device may not fully align with the bottom of the track, potentially causing track wobbling during installation and hindering welding. Therefore, an auxiliary positioning device for track installation is urgently needed to address these issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an auxiliary positioning device for track erection to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an auxiliary positioning device for track erection, comprising: a support base, wherein the outer surfaces of both ends of the upper end of the support base are provided with adjustment structures, and the upper end of the adjustment structure is provided with a fitting structure, and the upper end of the fitting structure is provided with a rail; the adjustment structure includes a support box, a rotating rod, a first gear, a second gear, a threaded rod, a first moving rod, a support rod, a collar, a moving groove, a second moving rod, a spring, a pulling rod, a first positioning hole, a second positioning hole, and a locking groove; the fitting structure includes a receiving plate, a motor, a third gear, a hinge base, a hinge rod, a fourth gear, and a connecting plate.

[0007] Preferably, the support box is provided in two sets, and the lower ends of both sets of support boxes are fixedly connected to the outer surfaces of the upper ends of the support base. The interior of the outer surfaces of the two sets of support boxes on opposite sides is connected to a rotating rod via bearings. One end of the rotating rod is fixedly connected to a first gear, and a second gear is meshed with the outer surface of one side of the first gear. A threaded rod is fixedly connected to the upper outer surface of the second gear, and a first movable rod is sleeved on the outer surface of the threaded rod. Support rods are fixedly connected to the outer surface of the upper end of the support box, and multiple sets of support rods are provided. A collar is fixedly connected to the upper end of each set of support rods. The interior of the outer surfaces of the opposite sides of the two sets of support boxes is open... The device includes a movable groove, with a second movable rod engaged inside the groove. A spring is fitted on the outer surface of the second movable rod, and a pull rod is fitted on the outer surface of one end of the second movable rod. A first positioning hole is formed inside the inner wall surface of one end of the movable groove, and a second positioning hole is formed inside the inner wall surface of the other end of the movable groove. A turntable is fixedly connected to the outer surface of the other end of the rotating rod, and a locking groove is formed on the outer side of the turntable. Multiple sets of locking grooves are provided. This design allows the first gear to drive the second gear to rotate by rotating the rotating rod, thereby causing the threaded rod to rotate, which in turn causes the first movable rod to move upward or downward on the outer surface of the threaded rod.

[0008] Preferably, the outer surface of the first moving rod is provided with a sliding groove, and multiple sets of sliding grooves are provided. The inner wall surface of the collar is fixedly connected with a slider, and the outer dimensions of the slider and the inner dimensions of the sliding groove are adapted to each other. This design allows the sliding groove to move synchronously with the outer surface of the slider when the first moving rod moves on the outer surface of the threaded rod.

[0009] Preferably, a limiting ring is fixedly connected to the outer surface of one end of the second moving rod, and the two ends of the spring abut against the surface of one side of the limiting ring and the inner wall surface of the pulling rod, respectively. This design allows the pulling rod to automatically reset after moving on the outer surface of one end of the second moving rod.

[0010] Preferably, the external dimensions of one end of the pull rod are adapted to the internal dimensions of the first positioning hole and the second positioning hole, and the external dimensions of the pull rod are adapted to the internal dimensions of the engaging groove. This design allows the outer surface of one end of the pull rod to be inserted into the interior of the first positioning hole and the second positioning hole.

[0011] Preferably, the receiving plate is provided in two sets, and the two sets of receiving plates are respectively fixedly connected to the outer surface of the upper end of the two sets of first moving rods. A motor is installed on the outer surface of the two sets of receiving plates on the side away from each other, and a third gear is fixedly connected to the output end of the motor.

A connecting plate is fixedly connected to the outer surface of the upper end of the hinge rod, and a rail is attached to the outer surface of the upper end of the connecting plate. The third gear and the fourth gear are meshed together. This design allows the output end of the motor to drive the third gear to rotate when the motor is started, and the third gear meshes and drives the fourth gear to rotate, thereby causing the hinge rod to rotate synchronously.

[0012] The technical effects and advantages of this utility model are as follows: By rotating the rotating rod, the rotating rod drives the first gear to rotate, and the first gear meshes and drives the second gear to rotate, thereby causing the threaded rod at the upper end of the second gear to rotate. This causes the first moving rod on the outer surface of the threaded rod to move up or down. Thus, the extension height of the first moving rod can be adjusted according to the difference in height between the rails, which facilitates the splicing and connection between rails and improves the practicality of the device to a certain extent.

[0013] By starting the motor, the output end of the motor drives the third gear to rotate, which in turn drives the fourth gear to rotate. The fourth gear then drives the hinge rod to rotate, which in turn drives the connecting plate to rotate. This allows the outer surface of the upper part of the connecting plate to fit against the bottom of the rail, thus preventing the rail from shaking during installation. This also facilitates welding between rails. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The track erection involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1, as Figures 1-4As shown, this embodiment proposes an auxiliary positioning device for track erection, including: a support base 1, with adjustment structures 2 provided on the outer surfaces of both ends of the upper end of the support base 1, and a fitting structure 3 provided on the upper end of the adjustment structure 2, and a rail 4 provided on the upper end of the fitting structure 3; the adjustment structure 2 includes a support box 21, a rotating rod 22, a first gear 23, a second gear 24, a threaded rod 25, a first moving rod 26, a support rod 27, a collar 28, a moving groove 29, a second moving rod 210, a spring 211, a pulling rod 212, a first positioning hole 213, and a second positioning hole 214. The support box 21 has two positioning holes 214 and engaging grooves 215. Two sets of support boxes 21 are provided, and the lower ends of both sets of support boxes 21 are fixedly connected to the outer surfaces of the upper ends of the support base 1. The inner surfaces of the two sets of support boxes 21, which are far apart from each other, are each connected to a rotating rod 22 by a bearing. One end of the rotating rod 22 is fixedly connected to a first gear 23, and a second gear 24 is meshed with the outer surface of one side of the first gear 23. A threaded rod 25 is fixedly connected to the outer surface of the upper end of the second gear 24, and a first moving rod 26 is sleeved on the outer surface of the threaded rod 25. The upper end of the support box 21... Support rods 27 are fixedly connected to the outer surface of the support box 21, and multiple sets of support rods 27 are provided. A collar 28 is fixedly connected to the upper end of each set of support rods 27. A movable groove 29 is opened inside the outer surface of one end of each of the two sets of support boxes 21, which are located away from each other. A second movable rod 210 is engaged inside the movable groove 29. A spring 211 is sleeved on the outer surface of the second movable rod 210. A pulling rod 212 is sleeved on the outer surface of one end of the second movable rod 210. A first positioning hole 213 is opened inside the inner wall surface of one end of the movable groove 29. The inner wall of the other end of the movable groove 29... The inner surface of the surface is provided with a second positioning hole 214. The outer surface of the other end of the rotating rod 22 is fixedly connected to a turntable, and the outer side of the turntable is provided with a locking groove 215. Multiple sets of locking grooves 215 are provided. The outer surface of the first moving rod 26 is provided with a sliding groove, and multiple sets of sliding grooves are provided. The inner surface of the inner wall of the collar 28 is fixedly connected with a slider, and the outer size of the slider and the inner size of the sliding groove are matched. This design allows the sliding groove to move on the outer surface of the slider, thereby avoiding the first moving rod 26 from deflecting when it moves on the outer surface of the threaded rod 25.

[0021] A limiting ring is fixedly connected to the outer surface of one end of the second moving rod 210. The two ends of the spring 211 abut against the surface of one side of the limiting ring and the inner wall surface of the pulling rod 212, respectively. The external dimensions of one end of the pulling rod 212 are adapted to the internal dimensions of the first positioning hole 213 and the second positioning hole 214, and the external dimensions of the pulling rod 212 are adapted to the internal dimensions of the engaging groove 215. This design allows the pulling rod 212 to automatically return to its original position after moving along the outer surface of one end of the second moving rod 210, thus enabling the pulling rod to... One end of the rod 212 is inserted into the first positioning hole 213 or the second positioning hole 214, which makes the rod 212 more stable when it is inserted into the first positioning hole 213 or the second positioning hole 214. At the same time, this design allows the outer surface of the rod 212 to engage with the engagement groove 215 when it is inserted into the first positioning hole 213, thereby positioning the position of the rotating rod 22 after rotation, and thus positioning the position of the first moving rod 26 on the outer surface of the threaded rod 25.

[0022] The rotating rod 22, the first gear 23, the second gear 24, the threaded rod 25, and the first moving rod 26 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0023] Example 2, as Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: the bonding structure 3 includes a receiving plate 31, a motor 32, a third gear 33, a hinge seat 34, a hinge rod 35, a fourth gear 36, and a connecting plate 37. Two sets of receiving plates 31 are provided, and the two sets of receiving plates 31 are respectively fixedly connected to the outer surfaces of the upper ends of the two sets of first moving rods 26. Motors 32 are installed on the outer surfaces of the two sets of receiving plates 31 on opposite sides, and the output end of the motor 32 is fixedly connected to the third gear 33. Hinges 34 are fixedly connected to the outer surfaces on both sides of the upper end of the receiving plate 31, and a hinge rod 35 is hingedly connected inside the hinge seat 34. A fourth gear 36 is fixedly connected to the outer surface of one end of the hinge rod 35. The outer surface of the upper end of the four gears 36 and the hinge rod 35 is fixedly connected to the connecting plate 37, and the outer surface of the upper end of the connecting plate 37 is attached to the rail 4. The third gear 33 and the fourth gear 36 are meshed together. This design starts the motor 32, so that the output end of the motor 32 drives the third gear 33 to rotate, and the third gear 33 meshes and drives the fourth gear 36 to rotate. The fourth gear 36 drives the hinge rod 35 to rotate, so that the hinge rod 35 drives the connecting plate 37 to rotate. This allows the outer surface of the upper end of the connecting plate 37 to be attached to the bottom of the rail 4, thereby avoiding instability when the rail 4 is placed on the outer surface of the connecting plate 37.

[0024] Motor 32 is a product that can be purchased directly on the market. Its principle, connection method and control method are existing technologies that are well known to those skilled in the art, so they will not be described in detail here.

[0025] Working principle: When the device is in use, starting the motor 32 causes the output end of the motor 32 to drive the third gear 33 to rotate, which in turn drives the fourth gear 36 to rotate. The fourth gear 36 then drives the hinge rod 35 to rotate, which in turn drives the connecting plate 37 to rotate. This allows the outer surface of the upper end of the connecting plate 37 to fit against the bottom of the rail 4. Next, rotating the rotating rod 22 causes the rotating rod 22 to drive the first gear 23 to rotate, which in turn drives the second gear 24 to rotate. This causes the threaded rod 2 at the upper end of the second gear 24 to rotate. 5. Rotation causes the first moving rod 26 on the outer surface of the threaded rod 25 to move upward or downward. At the same time, the groove on the outer surface of the first moving rod 26 moves on the outer surface of the slider on the inner wall surface of the collar 28, thereby preventing the first moving rod 26 from deviating when moving on the outer surface of the threaded rod 25. This ensures that the first moving rod 26 can move stably on the outer surface of the threaded rod 25. The extension height of the first moving rod 26 can be adjusted according to the drop between the rails 4. Subsequently, multiple sets of rails 4 can be connected and welded together, and the rails 4 can be prevented from shaking. The above is the complete working principle of this utility model.

[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
