[0048] REFERENCE Figure 1 and Figure 2 As shown in the drawings, a dynamic monitoring data processing system for the relative height of a trolley track includes:

[0049] The emission module 100 includes a fixed first mounting member 110 and an emission unit 120, the first mounting member 110 is connected with the trolley and slides along one of the trolley tracks, i.e. along the first trolley track 310;

[0050] The receiving module 200 includes a second mounting member 210 fixedly connected with the crown block and sliding along another crown block track, i.e., sliding along a second crown block track 320;

[0051] The transmitting unit 120 is oppositely arranged with the receiving unit 220; the transmitting unit 210 is configured to transmit a laser signal, and the receiving unit 220 is configured to receive and record the laser signal;

[0052] The data processing module 600 is communicatively connected with the receiving unit 220 and configured to calculate a height difference h between the crown block tracks according to a position of the laser signal;

[0053] The calibration module 700 is configured to measure a static height difference s between the crown block tracks and send the static height difference s to the data processing module 600; and a calculation formula of the height difference h is h = cos β · (x - d · tan α) - h'

[0054] In the formula, d is a distance between the crown block tracks, i.e., a distance between the first crown block track 310 and the second crown block track 320, x is a displacement of the laser signal on the receiving unit 220, α is an angle of the transmitting module 100 relative to the crown block track (i.e., the first crown block track 310), β is an angle of the receiving module 200 relative to the crown block track (i.e., the second crown block track 320), and h' is a calibration value.

[0055] A calculation formula of the calibration value h' is h' = a - s, where a is an initial height difference calculated by the data processing module 600 according to position data of the laser signal when the crown block is in a static state.

[0056] Specifically, the transmitting module 100 and the receiving module 200 can move with the crown block, and scanning and monitoring of the entire track can be realized by measuring attitude data of the transmitting module 100 and the receiving module 200, while real-time and dynamic reference monitoring are satisfied.

[0057] In some embodiments of the present application, referring to Figure 5 As shown in the figure, the calibration module 700 includes a static height difference measuring unit 710 and a track horizontal position calibration unit; the static height difference measuring unit 710 includes range finders 711 symmetrically fixed on both sides of the crown block track and a reflecting device 712 located below the range finders; and the track horizontal position calibration unit includes a plurality of groups of symmetrically distributed encoders 720, and the distance between the encoders 720 in each group is equal along a direction parallel to the crown block track.

[0058] In some embodiments of the present application, the distance measuring device 711 is a laser distance measuring device, and the distance between the reflection devices 712 is equal to the distance between the laser emitting points of the distance measuring device 711.

[0059] Specifically, two distance measuring devices 711 are fixedly installed on both sides of the first and second trolley tracks 310 and 320, i.e., they are stationary relative to the respective tracks. The number of the reflection devices 712 is also two, which are respectively located below the respective distance measuring devices 711. As shown in Figure 5 As shown, two equal-height columns are fixedly arranged on the ground below the trolley tracks, and the reflection devices 712 are fixedly arranged on the top surfaces of the columns; as the reference points, the distance between the centers of the cross sections of the two columns is equal to the distance between the laser emitting points of the two distance measuring devices 711. In use, when the distance measuring device 711 is just located directly above the reflection device 712, the laser beams emitted by the distance measuring device 711 can be simultaneously irradiated on the respective reflection devices 712, so as to collect and calculate the static height difference s between the first and second trolley tracks 310 and 320. For the arrangement of the encoders 720, the same number of encoders 720 are arranged on the first and second trolley tracks 310 and 320, and the positions of the encoders 720 are one-to-one corresponding. On one trolley track, the distance between the adjacent two encoders 720 is not less than 20 m or 50 m.

[0060] In some embodiments of the present application, as shown in Figure 3 The first and second mounting members 110 and 210 have the same structure. Taking the first mounting member 110 as an example, the first mounting member 110 comprises a first mounting cavity 111 and a first connecting portion 112. The emitting unit 120 is located in the first mounting cavity 111, and the first mounting cavity 111 is provided with an emitting end face 113 facing the receiving module 200. The first connecting portion 112 is located at the bottom of the first mounting cavity 111, and is in contact with and slides relative to the first trolley track 310.

[0061] Specifically, as shown in Figure 1 The first mounting member 110 can be made of a density board or a metal plate, and if the metal plate is used, it must be subjected to anti-corrosion treatment. The first mounting member 110 is further provided with a first light shielding plate 114 for shielding and protecting the emitting end face 113. The end face of the first mounting member 110 is an inverted trapezoidal structure, in which the first connecting portion 112 is located at the upper base of the trapezoidal structure, specifically a long-strip-shaped groove structure formed along the first trolley track 310. The width of the long-strip-shaped groove structure is not less than the width of the first trolley track 310, i.e., it is slightly greater than the width of the first trolley track 310.

[0062] During assembly, the first connecting part 112 is fastened onto the first overhead crane track 310. Furthermore, a wear-resistant layer is fixedly laid inside the groove structure of the first connecting part 112. This wear-resistant layer can be made of a wear-resistant canvas or similar material to increase the friction between the first connecting part 112 and the first overhead crane track 310.

[0063] The transmitting end face 113, which is a constituent plane of the first mounting cavity 111, is perpendicular to the top surface of the first crane track 310. That is, the transmitting end face 113 is a vertical surface facing the receiving module 200; the laser emission port of the transmitting unit 120 is located on the transmitting end face 113.

[0064] In addition, the first light-shielding plate 114 is arranged around the periphery of the emitting end face 113, and the length of its upper baffle is greater than the length of its lower baffle, which can effectively block strong light and avoid the influence of the external environment on the laser signal.

[0065] The emitting end face 113 is provided with a first wiping part 115, which rotates relative to a point on the emitting end face 113 to clean the laser signal emission port and prevent the emission intensity of the laser signal from being affected.

[0066] In some embodiments of the present invention, reference is made to... Figure 4 As shown, the transmitting unit 120 includes a laser 121, an optical fiber 122, and an optical fiber collimator 123; the two ends of the optical fiber 122 are respectively connected to the laser 121 and the optical fiber collimator 123; the laser is a point laser; the optical fiber collimator 123 is integrated into the transmitting end face 113, and the laser 121 and the optical fiber 122 are disposed in the first mounting cavity 111.

[0067] Specifically, the fiber collimator 123 is fixedly located at the center of the transmitting end face 113. During use, the laser emitted by the laser 121 is conducted through the optical fiber 122 and enters the fiber collimator 123 at the center of the transmitting end face 133 of the transmitting module 100, directing the laser towards the receiving module 200.

[0068] In some embodiments of the present invention, as described above, referring to Figure 2 As shown, the second mounting component 210 has the same structure as the first mounting component 110. Specifically, it includes a second mounting cavity 211 and a second connecting portion 212. The second mounting cavity 211 is provided with a receiving end face 213, which is disposed opposite to the transmitting end face 113. The second connecting portion 212 is fastened to the second trolley track 320.

[0069] The receiving unit 220 is provided with a photoelectric detection unit 221, which is in communication connection with a data processing module 600; the photoelectric detection unit 221 is integrated on the receiving end surface 213, and specifically, the photoelectric detection unit 221 adopts a two-dimensional PSD screen.

[0070] Similarly, the periphery of the receiving end surface 213 is provided with a second light shielding plate 214, so as to avoid the interference of sunlight and reflected light on the measurement results.

[0071] Similarly, the receiving end surface 213 is also provided with a second wiping part 215, which is in sliding connection with the receiving end surface 213; the length of the second wiping part 215 is not less than the vertical width of the two-dimensional PSD screen, so as to clean the two-dimensional PSD screen in time and avoid affecting the reception of the laser signal.

[0072] In some embodiments of the present application, the first mounting member 110 and the second mounting member 210 are both fixedly provided with a pose measurement unit 500, which is in communication connection with the data processing module 600, and is used for measuring the deflection angles alpha and beta; the pose measurement unit 500 adopts a micro gyroscope and an acceleration sensor, wherein the micro gyroscope mainly measures rotational related parameters, and the acceleration sensor mainly measures translational related parameters, and has the characteristics of low cost, low power consumption, small size and high stability.

[0073] In some embodiments of the present application, the communication mode of the data processing module 600 can be in communication connection with the receiving unit 220, the calibration module 700 and the pose measurement unit 500 through a wireless communication module or an electrically connected mode such as a cable.

[0074] In some embodiments of the present application, referring to FIG. Figure 4 As shown in the figure, for the mounting mode of the transmitting module 100 and the receiving module 200 and the crown block, specifically, the first mounting member 110 and the second mounting member 210 are both hinged to the crown block through a hinge. Therefore, during the operation of the crown block, the transmitting module 100 and the receiving module 200 will change the pose.

[0075] In some embodiments of the present application, the top of the first mounting member 110 and the second mounting member 210 are connected with the crown block through spring pressing plates 400, specifically, one end of the spring pressing plate 400 is fixedly connected with the crown block, and the other end is in abutment with the top of the first mounting member 110 and the second mounting member 210; accordingly, the top of the first mounting member 110 and the second mounting member 210 are provided with fixing members (not shown in the figure) for limiting the spring pressing plate 400. The spring pressing plate 400 applies pressure to the first mounting member 110 and the second mounting member 210, preventing them from falling off the first crown block rail 310 and the second crown block rail 320.

[0076] In some embodiments of the present application, the receiving unit 220 and the transmitting unit 120 are connected with the power supply module of the crown block, that is, the receiving unit 220 and the transmitting unit 120 are powered by the power supply module of the crown block, and at the same time, the first wiping part 115 on the first mounting member 110 and the second wiping part 215 on the second mounting member 210 can also be powered.

[0077] In some embodiments of the present application, the monitoring method of the dynamic monitoring data processing system comprises the following steps:

[0078] S1, install and adjust the positions of the transmitting module 100 and the receiving module 200, and the photoelectric detection unit 221 records the initial position C of the laser signal;

[0079] Specifically, after the transmitting module 100 and the receiving module 200 are fixed with the crown block through the hinge, the first connecting part 112 of the transmitting module 100 is buckled on the first crown block rail 310, and the second connecting part 212 of the receiving module is buckled on the second crown block rail 320; then a certain pressure is applied to the transmitting module 100 and the receiving module 200 by using spring pressing plates 400 respectively, to prevent them from falling off the crown block rail.

[0080] After the transmitting module 100 and the receiving module 200 are powered on, the crown block is in a stationary state at this time, the transmitting module 100 transmits laser, the photoelectric detection unit 221 of the receiving module 200 receives the laser signal, and then the hinge and the spring pressing plate 400 are adjusted, so that the laser emitted by the optical fiber collimator 123 photographs the center position of the photoelectric detection unit 221, that is, the initial position C, as shown in Figure 3 .

[0081] S2, the calibration unit 700 measures the static height difference s of the crown block rail and sends it to the data processing module 600; the data processing module 600 calculates the initial height difference a;

[0082] Specifically, after the crane rail is zeroed, the crane is stopped at a fixed position, the range finder 711 is made stationary above the reflecting device 712, the static height difference s of the crane rail is measured, and then the static height difference s is sent to the data processing module 600.

[0083] The data processing unit 600 calculates the initial height difference a of the crane rail according to the initial position C when the crane is static.

[0084] S3, start the crane to drive the transmitting module 100 and the receiving module 200 to slide along the crane rail, while the attitude measurement unit 500 and the receiving unit 220 collect data; the rail horizontal position calibration unit collects the position information of the crane rail and sends it to the data processing module 600.

[0085] Specifically, the data collection period is t, for example, t is 5ms, that is, every 5ms, the attitude measurement unit 500 and the receiving unit 220 synchronously collect data.

[0086] The attitude measurement unit 500 measures the deflection angle a of the transmitting module 100 relative to the first crane rail 310 and the deflection angle β of the receiving module 200 relative to the second crane rail 320; in this embodiment, the measurement of the attitude measurement unit 500 is realized by six micro gyroscopes and two accelerometers, and each deflection angle is measured by spherical polar coordinates and plane rectangular coordinates.

[0087] Specifically, the micro gyroscope on the attitude measurement unit 500 is used to measure the angular acceleration of the transmitting module 100 and the receiving module 200, and after twice integration, the deflection angle a and the deflection angle β are obtained.

[0088] The data collected by the receiving unit 220 is the moving position D of the laser signal on the photoelectric detection unit 221.

[0089] With the operation of the crane, the encoder 720 feeds back the position of the crane running on the rail in real time, that is, the position of the transmitting module 100 and the receiving module 200 on the rail can be sent to the data processing module 600.

[0090] S4, the data processing module calculates the height difference h of the crane rail according to the data in step S2.

[0091] Specifically, it includes the following steps:

[0092] S41, after the running of the head sheave, the data processing module 600 calculates the displacement x of the laser signal on the photoelectric detection unit 221, and the displacement x is the distance between the horizontal line where the initial position C is located and the horizontal line where the moving position D is located, that is, the horizontal displacement of the laser signal on the photoelectric detection unit 221 is ignored.

[0093] S42, the data processing module 600 calculates the calibration value h' = a-s according to the initial height difference a in step S2 and the received static height difference s.

[0094] S43, the data processing module 600 reads the calibration value h' and calculates the height difference h using the formula h = cos β · (x-d·tan α)-h', that is, the height difference h in step S32 is corrected by using the calibration value h' and then output.

[0095] In the actual working process, since there are problems of zero drift and error accumulation, the data needs to be calibrated. Although the data drift exists in three different sensors, since the embodiment focuses on the height difference of the two sides of the head sheave track, all errors can be expressed in the height difference during calibration, and therefore the height difference between the calibrated height difference and the standard value is defined as h', that is, the calibration value. When the second head sheave track 320 is higher than the first head sheave track 310, the calibration value h' is negative, and when the first head sheave track 310 is higher than the second head sheave track 320, the calibration value h' is positive.

[0096] S44, the data processing module 600 draws and outputs the relationship curve diagram of the height difference h and the period t; in this embodiment, the data processing module 600 also has a data transmission function, and can upload the relationship curve diagram of the height difference h and the period t to the cloud or the upper computer in real time, so that the operation personnel can determine the maintenance time of the head sheave track according to the curve diagram.

[0097] The technical scheme of the present application has the following technical effects compared with the prior art:

[0098] The present application can meet the needs of dynamic reference online monitoring, that is, it can meet the real-time and dynamic reference monitoring problems at the same time. Since the device monitors not the absolute height but the relative height difference of the two sides of the guide rail, the transmitting unit and the receiving unit can record the height difference of the track in real time by changing the light spot.

[0099] Meanwhile, the static height difference of the crown block track is collected by the calibration module, and the calibration value is calculated according to the initial height difference obtained by the receiving module, so that the height difference is calibrated, and the error caused by drift is overcome. The application does not need manual intervention, saves detection cost, avoids personnel safety accidents, and guarantees work efficiency. The transmitting module and the receiving module can move with the crown block, and the posture data of the transmitting module and the receiving module are measured, so that the whole track is scanned and monitored, especially in the lifting process, the stress deformation of the track under heavy load can be well monitored.

[0100] In the description of the above-described embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0101] The above merely describes specific implementations of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
