Abstract
Description
Technical Field
[0001] This application relates to the field of overhead contact line technology, and in particular to a test and adjustment device, which for the first time synchronizes the measurement and adjustment processes. Background Technology
[0002] The overhead contact system is a crucial component of electrified railways, continuously supplying power to high-speed electric locomotives (electric multiple units). The height difference, spacing, and positioning slope of various key components of the contact wire (catcher wire) adhere to strict standards. Inaccurate height difference detection or imprecise adjustment can lead to prolonged non-standard operation, potentially causing issues such as pantograph drilling, pantograph strikes, arcing, contact wire burns, or even network collapse (accidents).
[0003] Therefore, related technologies usually require the measurement of data such as elevation differences. However, the measurement of data such as elevation differences in related technologies usually requires multiple people to complete the measurement, which is a waste of manpower. Utility Model Content
[0004] Therefore, it is necessary to provide a measuring device to address the above technical problems, which allows one person to complete the measurement of data such as elevation difference, thus saving manpower.
[0005] This application provides a testing device, including a fixed base, a first elastic clamping wheel, a measuring rod, a second elastic clamping wheel, and a first indicating portion. The fixed base extends along a first direction, and the first elastic clamping wheel is provided at at least one end of the fixed base along the first direction, and the first elastic clamping wheel is used to press and fix it to a contact line. The measuring rod is disposed on the fixed base and is movable relative to the fixed base along the first direction and a second direction, respectively, the second direction being perpendicular to the thickness direction of the fixed base. The second elastic clamping wheel is disposed on the top of the measuring rod and is used to press and fix it to another contact line. The first indicating portion is disposed on the measuring rod, and the first indicating portion includes a plurality of first graduations spaced apart along the second direction.
[0006] In one embodiment, the detector further includes a sliding platform; the sliding platform is slidably connected to the fixed base along the first direction; the measuring rod is disposed on the sliding platform, the measuring rod is movable relative to the sliding platform along the second direction, and the measuring rod is rotatable relative to the sliding platform about an axis parallel to a third direction; the first direction, the second direction, and the third direction are perpendicular to each other.
[0007] In one embodiment, the tester further includes a clamp and an adjuster, the clamp being used to hold the test rod or other functional components; the clamp is detachably connected to the sliding platform via the adjuster.
[0008] In one embodiment, the adjusting member extends along the third direction and is threadedly connected to the clamp and the sliding platform, respectively.
[0009] In one embodiment, the detector further includes a slope meter disposed on the sliding platform.
[0010] In one embodiment, the slope meter includes an electrically connected slope meter body and an alarm module; the alarm module is used to issue an alarm signal when the slope measured by the slope meter body is equal to a preset value;
[0011] The fixed base has a first working surface on its top wall, and the sliding platform has a second working surface that is slidably connected to the first working surface. The slope is the angle between the line connecting the first measured point on the first working surface and the second measured point on the second working surface and the horizontal plane.
[0012] In one embodiment, the first elastic clamping wheel includes a first clamping wheel and a first elastic element; the first clamping wheel is connected to one end of the fixed base along the first direction via the first elastic element; the side wall of the first clamping wheel is recessed with a first annular groove, the first annular groove being arranged around the central axis of the first clamping wheel; and / or, the second elastic clamping wheel includes a second clamping wheel and a second elastic element; the second clamping wheel is connected to the top end of the measuring rod via the second elastic element; the side wall of the second clamping wheel is recessed with a second annular groove, the second annular groove being arranged around the central axis of the second clamping wheel.
[0013] In one embodiment, both the first elastic clamping wheel and the second elastic clamping wheel are omnidirectional wheels.
[0014] In one embodiment, the detector further includes a second indicator portion disposed on the fixed base; the second indicator portion includes a plurality of second scales spaced apart along a first direction.
[0015] In one embodiment, the tuner includes two first elastic clamping rollers; the two first elastic clamping rollers are respectively disposed at opposite ends of the fixed base along the first direction; and / or, the tuner includes two second indicating portions; the plurality of second scales include a first starting scale and a first ending scale; wherein the first starting scale of one second indicating portion points in the direction of the first ending scale, which is opposite to the direction of the first starting scale of the other second indicating portion pointing in the direction of the first ending scale, and both are parallel to the first direction.
[0016] In the technical solution of this application, when the adjustment device is used, the first direction can be parallel to the horizontal plane (or the rail surface), and the second direction is perpendicular to the horizontal plane (or the rail surface). Then, the first elastic clamping wheel is pressed and fixed on a contact line, and the measuring rod is moved relative to the fixed base along the first direction and / or the second direction, so that the second elastic clamping wheel on the measuring rod can press and fix on another contact line. In this way, the height difference between the two contact lines can be read through multiple first scales of the first indicator. When the adjustment process reaches the preset value, a tightening operation is performed. During this process, one person can operate the adjustment device to measure and adjust data such as height difference, which can save manpower and time and improve adjustment accuracy.

Detailed Implementation
[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0031] In related technologies, the measurement of data such as elevation differences is usually carried out in the following ways:
[0032] The first method involves using a contact wire measuring instrument to measure on the ground. However, this method cannot accurately determine the horizontal distance between the two contact wires in a single measurement; it requires repeatedly moving the measuring instrument along the rails to approximate the distance. Secondly, after the measurement is complete, a work vehicle drives under the equipment, and personnel on the vehicle adjust the measurement data against standards. A second measurement is then performed. Before the second measurement, the work vehicle must be moved away from under the equipment; otherwise, the second measurement is impossible. Additionally, personnel must protect the measuring personnel to prevent collisions. Therefore, this method requires at least three people (one on the work vehicle and two on the ground) to complete the measurement.
[0033] The second method involves manual measurement using a spirit level and measuring tape on the work vehicle. During measurement, one person holds the spirit level at a suitable horizontal distance, adjusting the height so that the bubble level is centered on the scale and maintaining this position. Another person uses the measuring tape to measure the height difference between the tape and the working surface of the higher contact wire. This method requires at least two people and demands high skill and close coordination. Furthermore, the repeated use of measuring tools throughout the process increases errors and reduces data reliability.
[0034] It is evident that both the first and second methods require multiple people to complete the measurement of data such as elevation differences, which is a waste of manpower.
[0035] Based on this, this application designs a measuring device that allows one person to measure data such as elevation difference, thus saving manpower.
[0036] Figure 1 A schematic diagram of the detector 10 in one embodiment of this application is shown. Figure 2 A schematic diagram of the structure of the fixed base 110, the first elastic clamping wheel 120 and the second indicator 130 in one embodiment of this application is shown.
[0037] Please refer to the following: Figure 1 and Figure 2 One embodiment of this application provides a tester 10, including a fixed base 110, a first elastic clamping wheel 120, a measuring rod 210, a second elastic clamping wheel 220, and a first indicator 230.
[0038] The fixed base 110 extends along the first direction F1, and at least one end of the fixed base 110 along the first direction F1 is provided with a first elastic pressing wheel 120, which is used to press and fix it to a contact line.
[0039] The measuring rod 210 is mounted on the fixed base 110 and is movable relative to the fixed base 110 along a first direction F1 and a second direction F2, respectively, with the second direction F2 perpendicular to the thickness direction of the fixed base 110. A second elastic clamping wheel 220 is mounted on the measuring rod 210 and is used to press and fix it to another contact line. A first indicating part 230 is mounted on the measuring rod 210 and includes a plurality of first graduations 231 spaced apart along the second direction F2.
[0040] The first elastic clamping wheel 120 refers to an elastic clamping wheel that is mounted on the fixed base 110 and can clamp and hold one of the contact lines.
[0041] The second elastic clamping wheel 220 refers to the elastic clamping wheel located at the top of the measuring rod 210 and capable of clamping and holding the other contact line.
[0042] It is understandable that the first direction F1 and the second direction F2 are perpendicular to each other.
[0043] When the adjuster 10 is in use, the first direction F1 can be made parallel to the horizontal plane, and the second direction F2 can be made perpendicular to the horizontal plane. Then, the first elastic clamping wheel 120 is pressed and fixed on a contact line, and the measuring rod 210 is moved relative to the fixed base 110 along the first direction F1 and / or the second direction F2, so that the second elastic clamping wheel 220 on the measuring rod 210 can press and fix on another contact line. In this way, the height difference between the two contact lines can be read through the multiple first scales 231 of the first indicator 230 (the height difference is the difference in height of the two contact lines in the second direction F2). During this process, one person can operate the adjuster 10 to measure and adjust the height difference and other data, which can save manpower.
[0044] In some embodiments, the center of the second elastic clamping roller 220 is located at an adjacent first scale 231, which is the zero scale.
[0045] In this way, the height of the contact line held and fixed by the second elastic clamping wheel 220 is aligned with the first scale 231, which is at zero. This makes it easier to directly read the first scale 231 corresponding to the height of the first elastic clamping wheel 120 on the fixed base 110, and thus more convenient to know the height difference between the two contact lines.
[0046] During the process of the first elastic clamping roller 120 pressing against the contact line 20, the first elastic element 122 is compressed along the second direction F2, so that the center of the first clamping roller 121 is at the same height as the top surface of the fixed base 110. The height of the top surface of the fixed base 110 can be easily read by the first indicator 230. Therefore, it is convenient to read the height of the contact line 20 pressed and fixed by the first elastic clamping roller 120.
[0047] In some embodiments, please refer to Figure 3 The first elastic pressing wheel 120 may include a first pressing wheel 121 and a first elastic element 122. The side wall of the first pressing wheel 121 is recessed with a first annular groove 1211. The first annular groove 1211 is arranged around the central axis of the first pressing wheel 121. The first pressing wheel 121 is connected to one end of the fixed base 110 along the first direction F1 through the first elastic element 122.
[0048] In this way, the first elastic element 122 can be compressed, so that the first pressing wheel 121 is pressed and fixed to the corresponding contact line 20 under the action of the elastic restoring force of the first elastic element 122, and the contact line 20 can be arranged to pass through the first annular wheel groove 1211 (the setting of the pressing wheel should meet the requirement that the center line of the wheel groove, the center line of the contact line and the 0mm scale line coincide), thereby improving the stability and reliability of the first elastic pressing wheel 120 pressing and fixing to the corresponding contact line.
[0049] In some embodiments, the second elastic clamping wheel 220 includes a second clamping wheel 221 and a second elastic element 222. The second clamping wheel 221 is connected to one end of the measuring rod 210 through the second elastic element 222. The side wall of the second clamping wheel 221 is recessed with a second annular groove (not shown in the figure), and the second annular groove is arranged around the central axis of the second clamping wheel 221.
[0050] In this way, the second elastic element 222 can be compressed, so that the second pressing wheel 221 is pressed and fixed to the corresponding contact line under the action of the elastic restoring force of the second elastic element 222, and the contact line can be passed through the second annular wheel groove, thereby improving the stability and reliability of the second elastic pressing wheel 220 pressing and fixing to the corresponding contact line.
[0051] During the process of the second elastic clamping wheel 220 pressing against the contact line 20, the second elastic element 222 is compressed along the second direction F2, so that the center of the second clamping wheel 221 is at the same height as the first scale 231 which is zero, making it easy to read the height of the contact line 20 pressed and fixed by the second elastic clamping wheel 220 through the first indicator 230.
[0052] In some embodiments, the first elastic clamping wheel 120 and the second elastic clamping wheel 220 are both omnidirectional wheels.
[0053] In actual operation, the angles of the first elastic clamping wheel 120 and the second elastic clamping wheel 220 can be adjusted according to the extension direction of the contact line so that the first elastic clamping wheel 120 and the second elastic clamping wheel 220 can better press and fix the corresponding contact line. For example, one contact line can be set through the first annular groove 1211 of the first elastic clamping wheel 120, so that the first elastic clamping wheel 120 can be better pressed and fixed on the corresponding contact line; similarly, another contact line can be set through the second annular groove of the second elastic clamping wheel 220, so that the second elastic clamping wheel 220 can be better pressed and fixed on the corresponding contact line.
[0054] In some embodiments, the detector 10 further includes a sliding platform 400, which is slidably connected to the fixed base 110 along a first direction F1. A measuring rod 210 is disposed on the sliding platform 400, and the measuring rod 210 is movable relative to the sliding platform 400 along a second direction F2, and the measuring rod 210 is rotatable relative to the sliding platform 400 about an axis parallel to a third direction F3. The first direction F1, the second direction F2, and the third direction F3 are all perpendicular to each other.
[0055] When the tester 10 is in use, the height of the second elastic clamping wheel 220 on the test rod 210 relative to the fixed base 110 can be set according to the required height difference between the two contact lines 20. Specifically, the first scale 231 of the plurality of first scales 231 of the first indicator 230 corresponding to this height can be aligned with the height of the center of the first elastic clamping wheel 120 on the fixed base 110. The center position of the second elastic clamping wheel 220 is set at the first scale of the plurality of first scales 231 of the first indicator 230, which is the zero mark. At position 231, the first elastic clamping wheel 120 can be pressed and fixed onto a contact line, and then the sliding platform 400 can be moved relative to the fixed base 110 along the first direction F1 to the corresponding position (this corresponding position can be determined according to the required distance between the two contact lines along the first direction F1, such as 500mm, 800mm, etc.), thereby causing the measuring rod 210 to rotate relative to the sliding platform 400 about an axis parallel to the third direction F3, thereby allowing the second elastic clamping wheel 220 on the measuring rod 210 to be pressed and fixed onto another contact line. If the angle between the measuring rod 210 and the fixed base 110 is greater than 90 degrees, it indicates that the distance between the two contact wires in the second direction F2 is too large. The distance between the two contact wires in the second direction F2 needs to be reduced. This can be done by simultaneously reducing the distance between the two contact wires in the second direction F2 and reducing the angle between the measuring rod 210 and the fixed base 110 until the angle between the measuring rod 210 and the fixed base 110 is 90 degrees. Similarly, if the angle between the measuring rod 210 and the fixed base 110 is less than 90 degrees, it indicates that the distance between the two contact wires is too large. If the distance between the two contact wires in the second direction F2 is too small, the distance between the two contact wires in the second direction F2 can be increased while the angle between the measuring rod 210 and the fixed base 110 is increased until the angle between the measuring rod 210 and the fixed base 110 is 90 degrees. In this way, the detection and adjustment of the height difference between the two contact wires can be carried out simultaneously using the detector 10. This can save manpower and reduce the number of detections and adjustments, thereby improving the adjustment efficiency of the detector 10 in adjusting the height difference between the two contact wires.
[0056] In some embodiments, in conjunction with reference Figure 1 and Figure 4 The detector 10 also includes a positioning bolt 500, which is threaded to the sliding platform 400 and can abut against the fixed base 110 in the second direction F2.
[0057] After the sliding platform 400 is moved relative to the fixed base 110 along the first direction F1 to the corresponding position, the sliding platform 400 can be positioned at the corresponding position by the positioning bolt 500, thereby improving the ease of use and reliability of the tester 10.
[0058] It can be, such as Figure 5As shown, the measuring rod 210 is detachably connected to the sliding platform 400 via an adjusting member 600. For example, the adjusting member 600 extends along a third direction F3 and is threadedly connected to both the measuring rod 210 and the sliding platform 400. The measuring rod 210 has a threaded elongated hole 211 that matches the adjusting member 600 and extends along a second direction F2. Thus, the adjusting member 600 can be loosened, allowing the measuring rod 210 to move relative to the sliding platform 400 along the second direction F2, or the measuring rod 210 to rotate relative to the sliding platform 400 about an axis parallel to the third direction F3.
[0059] Alternatively, the tester 10 may also include a clamp 700, which is used to hold the test rod 210 (e.g., Figure 6 As shown, the clamp 700 is detachably connected to the sliding platform 400 via an adjusting member 600. This allows the adjusting member 600 to be loosened, enabling the measuring rod 210 and the clamp 700 to move relative to the sliding platform 400 along the second direction F2, and also allowing the measuring rod 210 and the clamp 700 to rotate relative to the sliding platform 400 about an axis parallel to the third direction F3. Specifically, the adjusting member 600 extends along the third direction F3 and is threadedly connected to both the clamp 700 and the sliding platform 400. The adjusting member 600 can also be threadedly connected to the measuring rod 210.
[0060] The clamp 700 can be a mechanical gripper or a pneumatic finger (or a limiting elastic pin), and no specific restrictions are made here.
[0061] Regardless of the method used, the flexibility of the measuring rod 210 in detecting and adjusting elevation differences can be improved, thereby enhancing the ease of use and efficiency of the adjustment device 10.
[0062] In some embodiments, the fixed base 110 is provided with a guide rail 111, and the sliding platform 400 includes a slider, which is slidably disposed in the guide rail 111 along a first direction F1.
[0063] The sliding platform 400 is provided with a reading window 401 for partially exposing the second indicator 130. During the process of sliding the sliding platform 400 along the first direction F1, certain second scales 131 of the second indicator 130 can be read at any time through the reading window 401, thereby making it easier to know the displacement of the sliding platform 400 and the measuring rod along the first direction F1.
[0064] In some embodiments, the detector 10 further includes a slope meter 300, which is disposed on the sliding platform 400.
[0065] like Figure 7As shown, when it is necessary to measure the slope, the inclinometer 300 can be clamped onto the sliding platform 400. The inclinometer 300 can be used to measure the levelness of the fixed base 110, thereby keeping the fixed base 110 level and improving the accuracy of the height difference data between the two contact lines.
[0066] In some embodiments, the slope meter 300 includes an electrically connected slope meter body (not shown) and an alarm module (not shown). The slope meter body and the alarm module are integrated into one unit, featuring a lightweight and miniaturized design. The alarm module is used to issue an alarm signal when the slope measured by the slope meter body equals a preset value. The slope is the angle of the fixed base 110 relative to the horizontal plane.
[0067] Specifically, the top wall of the fixed base 110 has a first working surface, and the sliding platform 400 has a second working surface that is slidably connected to the first working surface. The slope is the angle between the line connecting the first measured point on the first working surface and the second measured point on the second working surface and the horizontal plane.
[0068] The alarm module can be an alarm light or an alarm horn; no specific restrictions are imposed here.
[0069] Preset values can be set as needed. For example, if the fixed base 110 is to be kept horizontal, the preset value can be set to zero. During the process of adjusting the height difference between the two contact lines, when the guide rail 111 is adjusted to a horizontal state, the alarm module will issue an alarm signal to remind the staff that the fixed base 110 has been adjusted to the correct position.
[0070] It is understandable that when the fixed base 110 and the guide rail 111 are adjusted to a horizontal state, the guide rail 111 is parallel to the first direction F1 and also parallel to the horizontal plane.
[0071] For example, the preset value can be set according to the required slope of the contact line. Typically, the first elastic clamping wheel 120 at one end of the fixed base 110 is pressed and fixed to the contact line, and the sliding platform 400 is extended along the positioner corresponding to the contact line. In this way, the sliding platform 400 can be moved along the extension direction of the positioner so that the sliding platform 400 abuts against the end of the positioner away from the contact line. Then, the positioning slope of the contact line can be adjusted by the positioner. When the slope of the contact line reaches the preset value, the alarm module will issue an alarm signal to remind the staff that the contact line has been adjusted to the required slope.
[0072] In some embodiments, the detector 10 further includes a second indicator 130 disposed on the fixed base 110, the second indicator 130 including a plurality of second scales 131 spaced apart along the first direction F1.
[0073] Thus, when adjusting the position of the measuring rod 210 relative to the fixed base 110 along the first direction F1, the measuring rod 210 can be adjusted to the corresponding position more conveniently and accurately through the multiple second scales 131 of the second indicator 130.
[0074] In some embodiments, the detector 10 includes two first elastic clamping rollers 120, which are respectively disposed at opposite ends of the fixed base 110 along the first direction F1.
[0075] The fixed base 110 is provided with first elastic clamping wheels 120 at both ends. The two first elastic clamping wheels 120 can be used to fasten the same contact line respectively, thereby changing the measuring rod 210 into a gap measuring instrument (i.e., adjustment measurement of small height difference or even horizontal position). The measuring rod 210 is moved back and forth within the measurement range of the second indicator 130. When the measuring rod 210 is in different positions along the first direction F1, the first scale 231 of the first indicator 230 is read respectively, thereby judging and checking the straightness of the contact line.
[0076] Specifically, the measuring range of the first indicator 230 is 600 mm, and the measuring range of the second indicator 130 is 1000 mm.
[0077] This allows for better fulfillment of the inspection and adjustment needs of multiple contact wires in the overhead contact system, thus broadening the application scope of the inspection and adjustment device 10.
[0078] In some embodiments, the detector 10 includes two second indicator sections 130, and a plurality of second scales 131 including a first start scale and a first end scale; wherein the first start scale of one second indicator section 130 points in the direction of the first end scale, which is opposite to the direction of the first start scale of the other second indicator section 130 pointing in the direction of the first end scale, and both are parallel to the first direction F1.
[0079] The first starting mark is the second mark 131 that starts from the plurality of second marks 131 on the second indicator 130.
[0080] The first termination mark is the second mark 131 that terminates among the plurality of second marks 131 of the second indicator 130.
[0081] Optionally, the two first elastic clamping rollers 120 are symmetrically arranged with reference to a reference plane perpendicular to the first direction F1, and the two second indicator parts 130 are symmetrically arranged with reference to the reference plane.
[0082] Thus, the fixed base 110 is provided with a first elastic clamping wheel 120 and a first starting scale of a second indicator 130 at both ends, which makes it convenient to select the corresponding first starting scale nearby and improves the reading convenience of the second indicator 130.
[0083] In some embodiments, the center of the first elastic clamping roller 120 is located at an adjacent second scale 131, which is the zero scale.
[0084] Normally, the first second mark 131 among the plurality of second marks 131 of the second indicator 130 is the zero mark.
[0085] The center of the first elastic clamping roller 120 is located at the zero mark, which helps to improve the levelness of the contact line held and fixed by the first elastic clamping roller 120, thereby improving the measurement accuracy of the height difference between the two contact lines.
[0086] 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.
