Description

Technical Field

[0001] The utility model relates to the technical field of steel measurement, in particular to a steel length measuring instrument. Background Art

[0002] After the rail welding base completes the rail welding, it is necessary to measure the length of the rail and spray the length data of the rail on the rail to facilitate subsequent railway rail replacement operations.

[0003] Currently, the rail welding base mainly relies on manual methods for long rail measurement. However, since a complete rail is composed of multiple short rails welded together, during the welding process, the short rails need to be cut or repaired by welding, which will cause a large error between the overall length of the complete rail and the sum of the lengths of the multiple short rails; and after welding, the rail is relatively long, with an overall length of up to 500 meters. Simply relying on manual measurement, the accuracy is very low.

[0004] Moreover, during the manual measurement process, it is necessary to mark the scale of the ruler in advance, accurately stop one end of the rail at the origin of the ruler, and record the scale of the ruler corresponding to the other end of the rail by manual reading to obtain the length of the complete rail; however, the rail is usually controlled to start and stop through a roller table line. If a 500-meter-long and approximately 30-ton rail is to be accurately parked at the origin of the ruler through the roller table line, it requires the control personnel to adjust it multiple times to barely align the end of the rail with the origin of the ruler, resulting in a very low efficiency in the length measurement process.

[0037] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0038] This embodiment provides a steel length measuring instrument, which at least includes a preset track, two induction components, and a fixed laser component.

[0039] The preset track is parallel to the steel rail to be measured, ensuring that the induction components and the laser components installed on the preset track can normally detect the steel rail to be measured.

[0040] In some implementation manners, the preset track can be a complete track, and all the induction components and the fixed laser components are arranged on the same track, so as to measure the steel rail to be measured.

[0041] In some implementation manners, the preset track can also include multiple sub-rails. Different sub-rails are respectively arranged at both ends of the steel rail to be measured, and each sub-rail is provided with an induction component and a fixed laser component, only detecting the end regions of the steel rail to be measured, so as to reduce the length of the preset track and save costs.

[0042] In this embodiment, the preset track includes a first sub-rail 4 and a second sub-rail. One induction component is slidably connected to the first sub-rail 4, and the other induction component is slidably connected to the second sub-rail. The first sub-rail 4 and the second sub-rail are respectively located at the left and right ends of the steel rail to be measured, and a fixed distance is always maintained between the first sub-rail 4 and the second sub-rail, so as to facilitate the induction components on the first sub-rail 4 and the second sub-rail to perform laser detection on the left and right ends of the steel rail to be measured.

[0043] In some implementation manners, the first sub-rail 4 and the second sub-rail can be on the same axis, and the first sub-rail 4 and the second sub-rail are on the same side of the steel rail to be measured, so that the induction components and the fixed laser components can measure the steel rail to be measured from the same side of the steel rail to be measured.

[0044] In some implementation manners, the first sub-rail 4 and the second sub-rail are distributed on different sides of the steel rail to be measured, which is equivalent to measuring the steel rail to be measured from different sides of the steel rail to be measured, and can also achieve the purpose of high-precision measurement.

[0045] In this embodiment, the first sub-rail 4 and the second sub-rail are distributed on different sides of the steel rail to be measured.

[0046] The induction components are used to detect the end positions of the steel rail to be measured. The two induction components are slidably connected to the preset rails, and there is a first fixed distance between the two induction components before measurement.

[0047] It should be noted that the distance between the two induction components before measurement is fixed and known. During measurement, the movement of each induction component on its corresponding preset rail can be controlled, so as to measure the distance between each induction component from its position before measurement to the end of the steel rail to be measured. Through the distances detected by each induction component and the first fixed distance between the two induction components before measurement, the length of the steel rail to be measured can be calculated.

[0048] In some embodiments, the induction component may refer to a first laser sensor 6, and the distance between it and the end of the steel rail to be measured is measured by a first laser sensor 6.

[0049] In this embodiment, the induction component includes two first laser sensors 6. The two first laser sensors 6 move synchronously, and there is a fixed distance between the two first laser sensors 6, and this fixed distance can be relatively small. As Figure 1 shown, Figure 1 the longitudinal double lines in refer to the laser beams emitted by the two first laser sensors 6. In each measurement, the measurement results of the two first laser sensors 6 can be calibrated with each other. If the time points of signal change of the two first laser sensors 6 differ greatly during the movement, an alarm prompt can be given; if the time points of signal change of the two first laser sensors 6 during the movement coincide with the fixed distance between the two first laser sensors 6, it means that the measurement is normal.

[0050] Under the condition of normal measurement, the two first laser sensors 6 in the same induction component detect simultaneously, record the moving duration of the two first laser sensors 6 in the same induction component, calculate the average value of the two moving durations, and use the value calculated according to the average value and the moving speed as the moving distance of this induction component, so as to improve the accuracy and reliability of the measurement result.

[0051] On the other hand, the two first laser sensors 6 in the same induction component detect simultaneously and move synchronously, so that the measurement task can still be continued by the other laser sensor when one of the laser sensors fails, improving the measurement efficiency.

[0052] Furthermore, in order to ensure that the two first laser sensors 6 can move synchronously, as Figure 2As shown, in this embodiment, a movable support 5 is further provided. The bottom end of the movable support 5 is slidably connected to a preset track. The movable support 5 extends upward from the bottom end to form a platform-like structure, and the platform-like structure is used to simultaneously install two first laser sensors 6 so that the two first laser sensors 6 move synchronously.

[0053] It should be noted that the first sub-track 4 can be an existing linear module. The linear module uses a motor to drive a belt through a pulley, and the movement of the belt drives the first laser sensor 6 on the movable support 5 to move along the guide rail. In addition, the linear module can also drive the first laser sensor 6 on the movable support 5 to move through other transmission mechanisms such as screws. The transmission mechanism is an existing technology, and its internal structure will not be described in detail here, as long as it can drive the first laser sensor 6 to move on the first sub-track 4.

[0054] Similarly, the moving manner of the second sub-track driving the first laser sensor 6 is the same, and the linear module is an existing device, and its internal structure and principle will not be repeated here.

[0055] A fixed laser component is provided between the two induction components. The fixed laser component is fixed on the preset track and is used to detect whether the rail to be measured is in place.

[0056] In some embodiments, the fixed laser component can be realized by a second laser sensor 7 to detect whether the rail to be measured is in place.

[0057] As Figure 1 shown, in this embodiment, the fixed laser component can be realized by at least two second laser sensors 7 together to detect whether the rail to be measured is in place. Among them, the second laser sensor 7 and the first laser sensor 6 are at the same height to ensure that the emitted laser can reach the surface of the rail to be measured; there is a second fixed distance between the two second laser sensors 7. In this embodiment, in order to make the device structure more compact, one of the second laser sensors 7 is fixed on the first sub-track 4, and the other second laser sensor 7 is fixed on the second sub-track.

[0058] Furthermore, in order to protect all the sensors on the sub-track, as Figure 2 、 Figure 3 shown, a first outer machine 3 is provided outside the first sub-track 4. At this time, the first outer machine 3 houses the first laser sensor 6 and the second laser sensor 7, and both the first laser sensor 6 and the second laser sensor 7 are arranged on the first sub-track 4, but only the first laser sensor 6 can reciprocate along the first sub-track 4. A first detection port is provided on the first outer machine 3 opposite to the first laser sensor 6 and the second laser sensor 7, and the first detection port is in a long strip shape to facilitate the movement measurement of the first laser sensor 6.

[0059] Similarly, the second sub-track housing is provided with a second external machine 9, and a second detection port is also provided at a position on the second external machine 9 opposite to the first laser sensor 6 and the second laser sensor 7, the purpose of which is to protect the first laser sensor 6 and the second laser sensor 7 on the second sub-track.

[0060] Since the distance between the first sub-track 4 and the second sub-track is fixed, the distance between the two can be approximated as the length of the rail to be measured, which is equivalent to the first sub-track 4 and the second sub-track being located at both ends of the rail to be measured respectively.

[0061] Similarly, there is a third fixed distance between the first external machine 3 and the second external machine 9, and the third fixed distance is similar to the length of the rail to be measured, so that the first external machine 3 and the second external machine 9 are fixed at both ends of the rail to be measured, and when the rail to be measured is in place, the end of the rail can be measured by the first laser sensor 6.

[0062] Since the first sub-track 4 and the second sub-track can be located on the same side or different sides of the rail to be measured, the first external machine 3 and the second external machine 9 can also be distributed on the same side of the rail to be measured, or the first external machine 3 and the second external machine 9 are distributed on different sides of the rail to be measured.

[0063] As Figure 1 shown, Figure 1 the longitudinal single line in the figure represents the laser emitted by the second laser sensor 7; this embodiment has two second laser sensors 7, the second laser sensors 7 cannot move, and the distance between the two second laser sensors 7 is also known. When the two second laser sensors 7 simultaneously detect the presence of the rail to be measured, the first laser sensor 6 is activated to move the first laser sensor 6 to achieve the purpose of measuring the length of the rail to be measured.

[0064] It should be noted that the detection principle of the second laser sensor 7 in this embodiment is the same as that of the first laser sensor 6, both of which determine whether the laser emitted by the laser sensor is reflected by an obstacle through the laser reflection principle, and determine whether there is an obstacle in front of the laser sensor by whether the reflected laser can be received, which will not be described in detail here.

[0065] During measurement, each induction component can move in the first direction or the second direction along its corresponding preset track, where the first direction is the direction away from the fixed laser component, and the second direction is the direction towards the fixed laser component. Specifically:

[0066] This embodiment can measure the lengths of rails to be measured with different lengths. When the rail to be measured with an unknown length moves along the roller path line to the area where the two induction components are located, the following situations may occur:

[0067] I. Neither of the two induction components is blocked by the rail to be measured (such as Figure 4 the scene shown);

[0068] II. One of the induction components is blocked by the rail under test while the other induction component is not blocked by the rail under test (as shown in the scenario of Figure 5 );

[0069] III. The situation where both induction components are blocked by the rail under test occurs (as shown in the scenario of Figure 6 ).

[0070] In this embodiment, the direction of controlling the movement of the induction component will also be different in different situations. Specifically:

[0071] When the first laser sensor 6 of any induction component detects an obstacle, determine this induction component as the first induction component 1, and control the first induction component 1 to start from its current initial position and perform axial movement along the first direction, where the first direction is the direction away from the second laser sensor 7;

[0072] When the first laser sensor 6 of any induction component does not detect an obstacle, determine this induction component as the second induction component 2, and control the second induction component 2 to start from its current initial position and perform axial movement along the second direction, where the second direction is the direction close to the second laser sensor 7.

[0073] Combined with the attached drawings, in Figure 5 the first direction is the direction of the right arrow in the figure, and the second direction is the direction of the left arrow in the figure.

[0074] In this embodiment, when any induction component starts to move, start the timing operation, and monitor the change of the induction signal output by the induction component during the movement in real time; when the induction signal output by the induction component changes at a certain position during the movement, from outputting the first signal to outputting the second signal, or from outputting the second signal to outputting the first signal, it means that the induction component moves to the position facing the end of the rail under test. At this time, according to the timing time, count the movement duration of this induction component, and the movement distance of this induction component can be calculated by combining the preset movement speed.

[0075] With the cooperation of the two induction components, calculate the movement distance of the first induction component 1 according to the movement duration of the first induction component 1 and the preset movement speed to obtain the first movement distance;

[0076] Calculate the movement distance of the second induction component 2 according to the movement duration of the second induction component 2 and the movement speed to obtain the second movement distance;

[0077] Calculate the length of the rail under test according to the first movement distance, the second movement distance and the fixed distance.

[0078] It should be noted that the calculation of the length of the rail to be measured is performed in the controller, and the calculation process can be completed through existing distance calculation formulas, which have been disclosed in the prior art and will not be described in detail here.

[0079] The controller is connected to each first laser sensor 6 and each second laser sensor 7, and is used to control the working states of each first laser sensor 6 and each second laser sensor 7, receive the detection signals of each first laser sensor 6, receive the detection signals of each second laser sensor 7, output the length of the rail to be measured, etc.

[0080] Furthermore, the rail length measuring instrument of this embodiment further includes:

[0081] A scanner 8 is installed on the first outer machine 3. As shown in Figure 2 、 Figure 3 , the scanning port of the scanner 8 faces outward towards the rail to be measured, and is used to scan the barcodes on the rail to be measured when the rail to be measured passes by.

[0082] Specifically, the scanner 8 is connected to the controller. The controller controls the working state of the scanner 8, and sends the scanned information to the controller for management. If the scanner 8 scans a valid code, the scan result will be compared with the previously obtained result to determine the information of the current rail to be measured; if there is no such result previously, it will be stored and managed; when the laser sensor cannot sense the rail, the barcode scanning module stops scanning.

[0083] Furthermore, the rail length measuring instrument of this embodiment further includes:

[0084] A painting device (not marked in the figure), which is connected to the controller and can move along the axis direction of the rail to be measured, and is used to perform specified information painting on the rail to be measured after receiving the length information of the rail to be measured. The specified information includes the length, rail type, working edge, etc. of the rail to be measured.

[0085] It should be noted that the painting device can adopt a manual control method or an automatic inkjet printer to implement the painting operation; the painting device receives the length information of the rail to be measured in real time through a network interface, generates corresponding painting instructions according to the length information, the model of the rail to be measured, etc., and the automatic inkjet printer sprays the length information, the model of the rail to be measured, etc. on the specified position of the rail to be measured after receiving the painting instructions. In addition, the painting device can automatically switch the painting content according to the information of different rails to be measured, improving the work efficiency.

[0086] Furthermore, the rail length measuring instrument of this embodiment further includes:

[0087] Anomaly alarm, which alarms the anomalies occurring in the whole system, including real-time alarming for abnormal bar code data collected, abnormal length information measured, abnormal device operation, etc.
