Description

Technical Field

[0001] This application relates to the technical field of turnout opening measurement tools, and in particular to turnout opening measurement tools. Background Technology

[0002] A turnout is a critical track connection device in a railway track system, enabling vehicles to smoothly switch from one track to another. A turnout consists of a switch rail and a stock rail. The distance between the switch rail and the stock rail in a repulsive state, known as the turnout's opening distance, is crucial to train safety and efficiency. Therefore, during the operation of a railway track system, it is necessary to measure the turnout's opening distance to ensure it remains within the standard range.

[0003] In related technologies, workers typically use tools such as measuring tapes to manually measure the turnout's opening. During maintenance periods, the distance between the switch rail and the stock rail is read and calculated using a measuring tape to obtain the opening value. Then, the measured value is compared with the standard opening value in the documentation to determine whether it meets the requirements.

[0004] However, manual reading and calculation of turnout values ​​are prone to errors. This can prevent the timely detection of potential safety hazards in the turnout, leading to potential malfunctions during prolonged operation, impacting train efficiency, and reducing the reliability of the turnout. Furthermore, the need to measure and compare values ​​during maintenance reduces maintenance efficiency, lowers work time utilization, and consequently affects the overall efficiency of maintenance work. Utility Model Content

[0005] Therefore, it is necessary to provide a turnout opening measurement tool to address the problems of easy errors and low measurement efficiency when measuring the opening value.

[0006] A turnout opening measurement tool, comprising:

[0007] A measuring unit extends along a first direction and has an abutment end for abutting against a first track;

[0008] The detection unit is mounted on the measuring unit. The detection unit has a first end and a second end that are arranged opposite to each other along the first direction. The distance between the first end and the abutment end along the first direction is the minimum value of the open range, and the distance between the second end and the abutment end along the first direction is the maximum value of the open range. The detection unit is used to detect the position of the second track.

[0009] In one embodiment, the measuring unit includes a first scale line extending along a first direction, the first scale line being used to position the detection unit;

[0010] The detection unit includes a second scale line, which extends along a first direction and is disposed between the first scale lines. One end of the second scale line is disposed at the first end, and the other end of the second scale line is disposed at the second end.

[0011] The line widths of the first and second scale lines are different;

[0012] Alternatively, the lines of the first and second scale marks may be different.

[0013] Alternatively, the first and second scale lines may be different colors.

[0014] In one embodiment, the detection unit is configured to be movably disposed on the measuring unit along a first direction to change the distance between the detection unit and the contact end along the first direction.

[0015] In one embodiment, the detection unit and the measurement unit are configured to be fixed by magnetic attraction, and the detection unit can move relative to the measurement unit in a first direction by external force to overcome the magnetic attraction.

[0016] In one embodiment, the detection unit has a slot and is slidably fitted onto the outside of the measuring unit along a first direction to change the distance between the detection unit and the contact end along the first direction.

[0017] In one embodiment, the detection unit has a through hole that communicates with a slot;

[0018] The turnout opening measurement tool also includes a locking unit, which is inserted into the through hole to fix the detection unit to the measuring unit.

[0019] In one embodiment, the measuring unit includes an abutment portion having an abutment end, the thickness of which gradually decreases in the direction away from the abutment end.

[0020] In one embodiment, the turnout opening measurement tool includes multiple measurement units and multiple detection units, which are set in a one-to-one correspondence. The detection units are set on the corresponding measurement units, and at least two detection units are set at different positions on the corresponding measurement units.

[0021] In one embodiment, the measuring unit has a connecting end, and the connecting end and the abutting end are respectively disposed at both ends of the measuring unit, and the connecting end is provided with a connecting hole;

[0022] The turnout opening measurement tool also includes a fixed unit, and the connection holes of multiple measurement units are rotatably fitted onto the fixed unit.

[0023] In one embodiment, the end of the connector includes an arcuate structure.

[0024] The aforementioned turnout opening measurement tool has its detection unit and the contact end positioned along a first direction within the opening range. Using this structure, during use, the contact end is brought into contact with the first side, and then the relative position of the second side and the detection unit is compared. If the second side is within the range of the detection unit, the turnout opening meets the requirements; if the second side is outside the detection unit, the turnout opening does not meet the requirements. This design eliminates the need for personnel to read and calculate values; only positional comparison is required. This avoids errors during value reading, allowing personnel to promptly identify potential safety hazards, ensuring safety and efficiency, and improving the reliability of turnout operation. Furthermore, during maintenance, there is no need to measure specific values; direct comparison is sufficient. This reduces operational steps, improves turnout maintenance efficiency, increases work time utilization, and ultimately ensures overall maintenance efficiency. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

[0045] See Figure 1 and Figure 2 This application provides a turnout opening range measuring tool, which includes a measuring unit 10 and a detection unit 20. The measuring unit 10 extends along a first direction and has an abutment end 11 for abutting against a first track 100. The detection unit 20 is disposed on the measuring unit 10 and has a first end and a second end disposed opposite to each other along the first direction. The distance between the first end and the abutment end 11 along the first direction is the minimum value of the opening range, and the distance between the second end and the abutment end 11 along the first direction is the maximum value of the opening range. The detection unit 20 is used to detect the position of a second track 200. The X direction is the first direction. Specifically, the first track 100 has a first side surface 110 on the side closer to the second track 200, and the second track 200 has a second side surface 210 on the side closer to the first track 100.

[0046] Applying the technical solution of this application, the distance between the detection unit 20 and the contact end 11 along the first direction is set within the opening range. With this structure, during use, the contact end 11 abuts against the first side 110, and then the relative position of the second side 210 and the detection unit 20 is compared. If the second side 210 is within the range of the detection unit 20, the turnout opening meets the requirements; if the second side 210 is outside the detection unit 20, the turnout opening does not meet the requirements. This setup eliminates the need for personnel to read and calculate values; only position comparison is required. This avoids errors during value reading, allowing personnel to promptly identify safety hazards, ensuring safety and efficiency, and improving the reliability of turnout operation. Furthermore, during maintenance, there is no need to measure specific values; direct comparison is sufficient. This reduces operational steps, improves turnout maintenance efficiency, increases work time utilization, and ultimately ensures the overall efficiency of maintenance work.

[0047] In some embodiments, the first track 100 is a switch rail and the second track 200 is a base rail, or the first track 100 is a base rail and the second track 200 is a switch rail.

[0048] See Figure 3 In some embodiments, the measuring unit 10 is equipped with two detection units 20. Since, under certain operating conditions, the turnout also includes a third rail, which is another base rail, when the first rail 100 is a switch rail and the second rail 200 is a base rail, one detection unit 20 corresponds to the travel between the first rail 100 and the second rail 200, and the other detection unit 20 corresponds to the travel between the first rail 100 and the third rail. The same principle applies when the first rail 100 is a base rail and the second rail 200 is a switch rail, and will not be elaborated further here.

[0049] Specifically, the measuring unit 10 includes a first scale line 12 extending along a first direction, used to position the detection unit 20. The detection unit 20 includes a second scale line 21 extending along the first direction, positioned between the first scale lines 12, with one end of the second scale line 21 positioned at the first end and the other end at the second end. The first scale line 12 and the second scale line 21 may use different line widths, different line types, or different colors. With this structure, the operator can set the position of the detection unit 20 according to the value of the first scale line 12, such that the distance between one end of the second scale line 21 and the contact end 11 along the first direction is the minimum value of the open range, and the distance between the other end of the second scale line 21 and the contact end 11 along the first direction is the maximum value of the open range. This design facilitates the processing of the detection unit 20 by staff. Furthermore, the difference between the first scale line 12 and the second scale line 21 makes it easier for staff to distinguish between them, thus facilitating verification of whether the opening value meets requirements. This also reduces the risk of misreading and further improves detection efficiency.

[0050] In some embodiments, the measuring unit 10 body and the detection unit 20 body are different colors.

[0051] In actual operation, the opening stroke values ​​of different types of turnouts are usually different. In some embodiments, multiple detection units 20 can be set on the measuring unit 10. The multiple detection units 20 are distributed at intervals along the first direction on the measuring unit 10, that is, the distances between the multiple detection units 20 and the contact end 11 are different. In this way, the multiple detection units 20 on the measuring unit 10 can correspond to multiple turnouts with different opening stroke values. This setting can improve the versatility of the turnout opening stroke measuring tool.

[0052] In some embodiments, the second scale lines 21 of the plurality of detection units 20 on the measuring unit 10 use different line widths, or different line types, or different colors. This arrangement facilitates the differentiation of the plurality of detection units 20 by the operator.

[0053] In some embodiments, when multiple detection units 20 are set on the measuring unit 10 to correspond to multiple turnouts with different opening values, the operator can record the line width, line type or color corresponding to the turnouts with different opening values ​​on the measuring unit 10.

[0054] In some embodiments, the detection unit 20 is configured to be movably disposed on the measuring unit 10 along a first direction to change the distance between the detection unit 20 and the contact end 11 along the first direction. With this configuration, when detecting multiple turnouts with different opening values, one detection unit 20 and one measuring unit 10 can meet the requirements, reducing the cost of turnout opening measurement tools. Workers can quickly adjust the position of the detection unit 20 as needed without changing other tools, improving the efficiency of on-site inspection operations.

[0055] See Figure 4 In another embodiment, the detection unit 20 and the measuring unit 10 are configured to be fixed by magnetic attraction. The detection unit 20 can move relative to the measuring unit 10 along a first direction by external force overcoming the magnetic attraction. With this configuration, magnetic attraction enables rapid positioning and stepless adjustment of the detection unit 20. The operator can easily move the detection unit 20, while the detection unit 20 provides sufficient holding force after being fixed by attraction to prevent displacement of the detection unit 20 due to accidental contact or changes in the position of the measuring tool during the measurement process, thus ensuring the stability of the measurement.

[0056] In some embodiments, the measuring unit 10 is provided with a plurality of magnetically fixed detection units 20 to correspond to different types of turnouts. This arrangement can reduce the number of times the detection units 20 need to be moved, thereby further improving maintenance efficiency.

[0057] See Figure 5 The detection unit 20 has a slot 22 and is slidably fitted onto the outside of the measuring unit 10 along a first direction to change the distance between the detection unit 20 and the abutment end 11 along the first direction. This arrangement facilitates the assembly of the detection unit 20 and ensures the stability and straightness of the detection unit 20 during sliding, thereby improving the positioning accuracy.

[0058] In some embodiments, the measuring unit 10 is provided with a plurality of detection units 20 to correspond to different types of turnouts. This arrangement can reduce the number of times the sliding detection unit 20 is used, thereby further improving maintenance efficiency.

[0059] See Figure 6 The detection unit 20 has a through hole 23, which communicates with the slot 22. The turnout opening measuring tool also includes a locking unit 30, which passes through the through hole 23 to fix the detection unit 20 onto the measuring unit 10. With this configuration, when the detection unit 20 slides to the target position, tightening the locking unit 30 in the through hole 23 generates a locking force, fixing the detection unit 20 onto the measuring unit 10 and preventing displacement during subsequent measurements, thus ensuring the reliability of the measurement reference.

[0060] In some embodiments, the locking unit 30 is a bolt or a set screw.

[0061] See Figure 7 The measuring unit 10 includes an abutment portion 13, which has an abutment end 11. The thickness of the abutment portion 13 gradually decreases in the direction away from the abutment end 11. With this configuration, when the abutment end 11 abuts against the first side surface 110, the abutment portion 13 has greater structural strength, preventing the abutment portion 13 from bending and deforming due to force, thus ensuring the stability of the reference.

[0062] See Figure 8 In another embodiment, the turnout opening measurement tool includes multiple measuring units 10 and multiple detection units 20, with each measuring unit 10 and detection unit 20 configured in a one-to-one correspondence. The detection units 20 are positioned on corresponding measuring units 10, with at least two detection units 20 positioned at different locations on the corresponding measuring units 10. This configuration allows the turnout opening measurement tool to measure different types of turnouts, improving detection efficiency and effectively avoiding errors caused by frequently consulting drawings or memorizing different opening values, thus ensuring the accuracy of the detection.

[0063] In some embodiments, multiple detection units 20 are configured one-to-one with multiple types of turnouts, and the corresponding turnout names are marked on the measurement units 10 fixed to the detection units 20.

[0064] Specifically, the measuring unit 10 has a connecting end 14, with the connecting end 14 and the abutment end 11 respectively located at both ends of the measuring unit 10. The connecting end 14 is provided with a connecting hole 15. The turnout opening measuring tool also includes a fixing unit 40, on which the connecting holes 15 of the multiple measuring units 10 are rotatably fitted. This arrangement facilitates the storage of the measuring tool, making it convenient for staff to carry and store. Simultaneously, it facilitates use by staff, who can rotate the measuring unit 10 to the required angle.

[0065] In some embodiments, the fixing unit 40 includes a first stop 41, a fixing rod 42, and a second stop 43. The first stop 41 and the second stop 43 are respectively fixed at both ends of the fixing rod 42, and a plurality of measuring units 10 are rotatably disposed on the fixing rod 42.

[0066] The end of the connecting end 14 includes an arc-shaped structure 141. This design prevents the measuring unit 10 from causing injury to workers during rotation, thus ensuring the health of the workers.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
