Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, specifically to a fine-tuning and positioning device for laying turnout sleepers on ballastless turnouts. Background Technology

[0002] In the installation of turnout sleepers, traditional sleepers are typically not used; instead, precast track slabs or integral track bed structures are employed. Ballastless track, using precast concrete structures instead of traditional sleepers, offers higher stability, durability, and precision, making it suitable for high-speed railways. Laying turnout sleepers in ballastless track eliminates the need for transition structures in the turnout area, enabling factory production and rapid on-site installation. During sleeper installation using ballastless track technology, the two rails are aligned with the starting point of the ballastless track, and the center position of each sleeper is accurately marked on the rails according to the design drawings. Using a pry bar or rubber mallet with a rubber sleeve, the sleepers are manually adjusted to the marked line position, ensuring the sleeper spacing matches the design drawings. Before the concrete pouring of the track bed slab in the turnout section, the positioned turnout sleepers require a first and second fine-tuning to ensure track accuracy and stability. Fine-tuning requires accurate positioning of the turnout sleeper spacing to ensure that the deviation is within the required range; excessive deviation directly affects the smoothness of the railway track.

[0003] Currently, the method for locating turnout sleeper spacing involves measuring the distance between adjacent sleepers sequentially using a measuring ruler. Firstly, this sleeper-by-sleep measurement method is prone to cumulative errors. Secondly, measuring adjacent sleepers requires multiple people working together, and different personnel may have differing opinions on the selection of reference points, necessitating constant communication and verification, leading to significant measurement errors and low work efficiency.

[0004] The purpose of this utility model is to provide a fine-tuning and positioning device for laying turnout sleepers in ballastless turnouts, so as to solve the problems of low efficiency, poor accuracy and difficulty in ensuring consistency of marking and measuring points mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a fine-tuning and positioning device for laying turnout sleepers on ballastless turnouts, including a first spacer and a second spacer. A first positioning hole is formed on the lower surface of the first spacer, extending axially along the first spacer and matching the head of the sleeper bolt. When the first positioning hole matches the head of the sleeper bolt, the central axis of the first positioning hole and the central axis of the sleeper bolt are on the same straight line. A first positioning mark is provided on the top surface of the first spacer, located on the straight line containing the central axis of the first positioning hole. The second distance measuring device includes a positioning component and a clamping component. A second positioning hole is provided on the bottom surface of the positioning component. The second positioning hole extends along the axial direction of the positioning component and matches the head of the turnout bolt. When the second positioning hole matches the head of the turnout bolt, the central axis of the second positioning hole and the central axis of the turnout bolt are on the same straight line. A second positioning mark is provided on the top surface of the positioning component. The second positioning mark is located on the straight line where the central axis of the second positioning hole is located. The clamping component is fixedly mounted on the positioning component. The clamping component is used to clamp one end of the turnout spacing measuring ruler, providing tension to the turnout spacing measuring ruler, and at the same time, making the second positioning mark located within the measurement reading area of ​​the turnout spacing measuring ruler.

[0006] Furthermore, the clamping component includes a bracket, a nut, and a clamping bolt. One end of the bracket is fixedly connected to the positioning component, and the other end of the bracket extends above the positioning component. The nut is fixedly connected to the other end of the bracket, and the axis of the nut is perpendicular to the top surface of the positioning component. The clamping bolt is threadedly connected to the nut, and the minimum length of the clamping bolt must be such that the bottom surface of the clamping bolt can abut against the top surface of the positioning component by rotating the clamping bolt.

[0007] Furthermore, a first threaded hole is provided on the side wall of the positioning component, and one end of the first threaded hole passes through the side wall of the second positioning hole and is connected to the second positioning hole; the ballastless turnout sleeper fine adjustment positioning device also includes a first positioning bolt, the first positioning bolt is threadedly connected to the first threaded hole, and the threaded end of the first positioning bolt passes through the side wall of the second positioning hole and abuts against the side wall of the sleeper bolt head.

[0008] Furthermore, the first spacer is a cylindrical structure, and the first positioning hole is a cylindrical structure.

[0009] Furthermore, the positioning component is a cylindrical structure, and the second positioning hole is also a cylindrical structure.

[0010] Furthermore, both the first positioning mark and the second positioning mark are cylindrical through holes. The central axis of the first positioning mark coincides with the central axis of the first spacer, and the central axis of the second positioning mark coincides with the central axis of the positioning component.

[0011] Furthermore, the support includes a top plate and a vertical plate. One end of the top plate is fixedly connected to one end of the vertical plate, and the other end of the top plate is connected to a nut. The other end of the vertical plate is fixedly mounted on the positioning component, so that the other end of the top plate is located above the positioning component.

[0012] Furthermore, a second threaded hole is also provided on the side wall of the positioning component opposite to the first threaded hole. One end of the second threaded hole passes through the side wall of the second positioning hole and is connected to the second positioning hole. The ballastless turnout sleeper fine adjustment positioning device also includes a second positioning bolt. The second positioning bolt is threadedly connected to the second threaded hole, and the threaded end of the second positioning bolt passes through the side wall of the second positioning hole and abuts against the side wall of the sleeper bolt head.

[0013] Furthermore, there are multiple first distance measuring devices, all of which have the same structure, and there are two second distance measuring devices, both of which have the same structure.

[0014] This utility model has the following advantages over the prior art:

[0015] 1. This utility model ensures that the measurement reference point is accurately and consistently positioned and marked on the top center line of the spacer by precisely matching the positioning holes at the bottom of the first and second spacers with the head of the turnout bolt, and by having corresponding positioning marks on the top.

[0016] 2. This utility model securely fixes one end of the measuring ruler with the clamping component on the second distancer, making it precisely aligned with the positioning mark and maintaining a perpendicular state. This effectively prevents measurement errors caused by the measuring ruler being skewed, having insufficient or uneven tension.

[0017] 3. This utility model uses the full-length measurement method. The measuring ruler is fixed at both ends of the measurement section using the clamping components on the second distancer, and the first distancer is used for accurate positioning in the middle of the measurement section. The usage of this utility model is essentially a direct point-to-point measurement across multiple turnout sleepers, rather than accumulating the measurements one sleeper at a time. This completely avoids the cumulative error caused by moving the measuring ruler multiple times and superimposing the readings. At the same time, it simplifies the operation process, makes it easier to operate, and effectively improves the measurement accuracy and efficiency. Attached Figure Description

[0029] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] like Figures 1 to 5As shown, this utility model embodiment provides a fine-tuning and positioning device for laying turnout sleepers on ballastless turnouts, including a first spacer 1 and a second spacer 2. A first positioning hole 11 is formed on the lower bottom surface of the first spacer 1, extending axially along the first spacer 1. The first positioning hole 11 matches the head of the turnout sleeper bolt, such that when the first positioning hole 11 matches the head of the turnout sleeper bolt, the central axis of the first positioning hole 11 and the central axis of the turnout sleeper bolt are on the same straight line. A first positioning mark 12 is formed on the top surface of the first spacer 1, located on the straight line where the central axis of the first positioning hole 11 lies. The second spacer 2 includes a positioning component 3 and a clamping component 4. A second positioning hole 31 is formed on the lower bottom surface of the positioning component 3, extending axially along the positioning component 3. The second positioning hole 31 matches the head of the turnout sleeper bolt, such that when the second positioning hole 31 matches the head of the turnout sleeper bolt, the central axis of the second positioning hole 31 and the central axis of the turnout sleeper bolt are on the same straight line. A second positioning mark 32 is provided on the top surface of the positioning component 3, and the second positioning mark 32 is located on the straight line where the central axis of the second positioning hole 31 is located. The clamping component 4 is fixedly installed on the positioning component 3. The clamping component 4 is used to clamp one end of the turnout sleeper spacing measuring ruler, provide tension to the turnout sleeper spacing measuring ruler, and at the same time make the second positioning mark 32 located in the measurement reading area of ​​the turnout sleeper spacing measuring ruler.

[0031] In this embodiment, the positioning holes at the bottom of the first distance measuring device 1 and the second distance measuring device 2 are matched with the heads of the turnout bolts, and the positioning marks on the top of the first distance measuring device 1 and the second distance measuring device 2 correspond to the center positions of the corresponding turnout bolt heads. The positioning marks can be recorded and the scale of the measuring ruler can be used to ensure that the measurement reference point is accurately and consistently positioned and marked on the top center line of the distance measuring device, thereby improving measurement accuracy and work efficiency.

[0032] like Figure 1As shown, the clamping component 4 includes a bracket 41, a nut 42, and a clamping bolt 43. One end of the bracket 41 is fixedly connected to the positioning component 3, and the other end of the bracket 41 extends above the positioning component 3. The nut 42 is fixedly connected to the other end of the bracket 41, and the axis of the nut 42 is perpendicular to the top surface of the positioning component 3. The clamping bolt 43 is threadedly connected to the nut, and the minimum length of the clamping bolt 43 must be sufficient to allow the bottom surface of the clamping bolt 43 to abut against the top surface of the positioning component 3 by rotating the clamping bolt 43. In this embodiment, the bracket 41 includes a top plate 44 and a vertical plate 45. One end of the top plate 44 is fixedly connected to one end of the vertical plate 45, and the other end of the top plate 44 is connected to the nut 42. The other end of the vertical plate 45 is fixedly mounted on the positioning component 3, so that the other end of the top plate 44 is located above the positioning component. By tightening the clamping bolt 43, its bottom end moves downward and finally presses against the measuring scale placed on the top surface of the positioning component 3, firmly fixing it to the top surface of the positioning component 3, preventing the measuring scale from sliding, tilting or shifting during the measurement process, and achieving high-precision and high-efficiency measurement.

[0033] like Figure 2 As shown, the positioning component 3 has a first threaded hole on its side wall, one end of which passes through the side wall of the second positioning hole 31 and communicates with it. The positioning component 3 also includes a first positioning bolt 51, which is threadedly connected to the threaded hole, and the threaded end of the first positioning bolt 51 passes through the side wall of the second positioning hole 31 and abuts against the side wall of the turnout sleeper bolt head. In this embodiment, a second threaded hole is also provided on the side wall of the positioning component 3 opposite to the first threaded hole, one end of which passes through the side wall of the second positioning hole 31 and communicates with it. The turnout sleeper fine-tuning positioning device for ballastless turnouts also includes a second positioning bolt 52, which is threadedly connected to the second threaded hole, and the threaded end of the second positioning bolt 52 passes through the side wall of the second positioning hole 31 and abuts against the side wall of the turnout sleeper bolt head. By tightening the first positioning bolt 51 and the second positioning bolt 52, the positioning component 3 is firmly held in place by the bolt's clamping force, eliminating any relative displacement or shaking between the second spacer 2 and the bolt. During the measurement process, lateral forces may be generated by tightening the measuring ruler, personnel operation, or environmental vibration. The clamping force formed by the bolts on both sides can effectively resist these external interferences and prevent the device from sliding, rotating, or tilting relative to the turnout bolt during measurement.

[0034] like Figure 4 As shown, the first spacer 1 is a cylindrical structure, and the first positioning hole 11 is a cylindrical structure. Figure 1As shown, the positioning component 3 has a cylindrical structure, and the second positioning hole 31 has a cylindrical structure. In this embodiment, both the first positioning mark 12 and the second positioning mark 32 are cylindrical through holes. The central axis of the first positioning mark 12 coincides with the central axis of the first distancer 1, and the central axis of the second positioning mark 32 coincides with the central axis of the positioning component 3. The first distancer 1, the positioning component 3, the first positioning hole 11, the second positioning hole 31, the first positioning mark 12, and the second positioning mark 32 all adopt a cylindrical structure. This structure is widely used and easy to process, which can effectively reduce the manufacturing cost of the device. The cylindrical structure of the first positioning hole 11 and the second positioning hole 31 also allows the first distancer 1 and the second distancer 2 to be adapted to the head of the forklift bolt from any direction, avoiding angle adjustment during installation and effectively improving the efficiency of measurement work.

[0035] In this embodiment, there are multiple first distance measuring devices 1, all of which have the same structure. There are two second distance measuring devices 2, both of which have the same structure. The measurement is performed using the full-length measurement method. At both ends of the measurement section, the clamping components on the second distance measuring devices 2 are used to fix the measuring ruler. At the middle of the measurement section, the first distance measuring devices 1 are used for accurate positioning. The usage method in this embodiment is essentially a direct point-to-point measurement across multiple turnout sleepers, rather than accumulating the measurements one sleeper at a time. This completely avoids the cumulative error caused by moving the measuring ruler multiple times and superimposing the readings. At the same time, it simplifies the operation process, facilitates single-person operation, and effectively improves the measurement accuracy and efficiency.

[0036] In this embodiment, the process of using the ballastless turnout sleeper fine-tuning and positioning device is as follows:

[0037] When two second distance measuring devices 2 are used simultaneously, one person can complete the measurement independently:

[0038] Step 1: Determine the start and end points of the section to be measured. Install the second spacer 2 on the head of the turnout bolt at the start and end points and tighten the first positioning bolt 51 and the second positioning bolt 52. Install the first spacer 1 on the head of all turnout bolts between the start and end points.

[0039] Step 2: By rotating the clamping bolt 43 on the second distancer 2 at the starting point, fix the starting end of the measuring ruler to the upper surface of the positioning component 3, and ensure that the second positioning mark 32 is located within the measurement reading area of ​​the fork sleeper spacing measuring ruler.

[0040] Step 3: Tighten the measuring ruler at the end of the measuring section, and fix the measuring ruler on the upper surface of the positioning component 3 by rotating the clamping bolt 43 on the second distancer 2 at that position. Then, the reading can be recorded according to the scale of the measuring ruler corresponding to the positioning marks on all distancers.

[0041] When using only one second rangefinder 2, two people can work together to complete the measurement:

[0042] Step 1: Determine the start and end points of the section to be measured. Install the second spacer 2 on the head of the turnout bolt at the start point and tighten the first positioning bolt 51 and the second positioning bolt 52. Install the first spacer 1 on the head of all turnout bolts at the end point and between the start and end points.

[0043] Step 2: By rotating the clamping bolt 43 on the second distancer 2 at the starting point, fix the starting end of the measuring ruler to the upper surface of the positioning component 3, and ensure that the second positioning mark 32 is located within the measurement reading area of ​​the fork sleeper spacing measuring ruler.

[0044] Step 3: At the end of the measurement section, one person is responsible for pulling the measuring ruler taut, while another person reads and records the value of the measuring ruler according to the positioning mark on the distance measuring device.
