Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of crane operation position detection and verification, and in particular to a crane operation position detection and verification device and method. Background Art
[0002] Cranes are common material handling equipment in corporate production. The position detection and positioning accuracy of cranes have a vital impact on the safety and automated operation of cranes. In particular, cranes with a high degree of automation need to scan the material shape data in the operating area and accurately locate and load and unload goods. The position detection function is particularly important in this case.
[0003] There are many forms of continuous position detection devices for crane translation mechanisms, but continuous position detection devices cannot verify their own detected position information. Therefore, it is necessary to introduce an independent position detection and verification device to verify and correct the continuous position detection information. When the continuous position information is detected to be inconsistent with the verification information or the error is large, an emergency processing signal should be issued. For example: the encoder installed on the center axis of the wheel and rotating with the wheel calculates the distance by recording the number of rotations. Since the crane runs on rails, the wheels may slip. Over time, the encoder distance measurement produces cumulative errors, resulting in large positioning deviations.
[0004] Through years of field practice and investigation and research, it is found that if a suitable distance is selected, a detection point is set at every certain position, and the position information is verified and corrected, the errors formed during operation can be discovered and eliminated in time; when the position detection device cannot detect the position normally, the position data often does not change or changes abnormally. When running to the detection point, the controller can judge that the deviation between the preset value and the current value is obviously too large, and it is concluded that the position detection system has a serious abnormality. According to the conventional method, a detection switch and a set of detection boards need to be set for each detection point. In order to avoid spatial interference, the detection switch and the detection board must be staggered. However, the operating distance of the crane is mostly tens or even hundreds of meters, and the installation height ranges from more than ten meters to tens of meters. Using this conventional method requires a large installation space, which increases the construction volume and the danger of installation. Summary of the invention

DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] Combine the following Figure 1 and Figure 2 A crane operation position detection and verification device according to an embodiment of the present invention is described, comprising:
[0033] The induction switch group is arranged on the crane, and the crane can drive the induction switch group to move along the length direction of the track beam. The induction switch group includes a first induction switch 100 and a second induction switch 200 which are arranged in sequence along the length direction of the track beam;
[0034] A detection plate 400 group, the detection plate 400 group is arranged opposite to the track beam in the vertical direction, the detection plate 400 group includes a plurality of detection plates 400 arranged along the length direction of the track beam, and the detection plate 400 is adapted to detect both the first induction switch 100 and the second induction switch 200;
[0035] The controller is electrically connected to the inductive switch group. It is understandable that the inductive switch group is a device for detecting and transmitting detection signals and is arranged on the crane to ensure the synchronous movement of the inductive switch group and the crane. The crane can freely slide back and forth along the length direction of the track beam. The inductive switch group is arranged on one side of the crane close to the installation position of the detection plate 400 to ensure that the inductive switch group always remains stable during the movement of the crane, thereby improving the accuracy of the detection.
[0036] The inductive switch group includes a first inductive switch 100 and a second inductive switch 200, and the first inductive switch 100 and the second inductive switch 200 are sequentially arranged along the length direction of the track beam. Figure 1 As described above, the first induction switch 100 is disposed on the right side of the second induction switch 200 .
[0037] Furthermore, the detection plate 400 group is arranged above the track beam, so that the detection plate 400 group is arranged opposite to the track beam in the vertical direction. The detection plate 400 group includes a plurality of detection plates 400 arranged along the length direction of the track beam, and each detection plate 400 is horizontally arranged above the track beam to ensure that the bottom detection surface of the detection plate 400 is opposite to the upper end surface of the track beam, that is, opposite to the plane where the first induction switch 100 and the second induction switch 200 are located. Each detection plate 400 is adapted to detect the first induction switch 100 and the second induction switch 200, and the height of the detection plate 400 is within the induction detection range of the first induction switch 100 and the second induction switch 200.
[0038] The first induction switch 100 and the second induction switch 200 are horizontally arranged on the crane and close to the track beam at the same height. The detection plate 400 is arranged above the track beam. The detection plates 400 have the same height and do not exceed the induction detection range of the first induction switch 100 and the second induction switch 200. The multiple detection plates 400 can be arranged at equal intervals or according to actual needs.
[0039] Furthermore, the controller is electrically connected to the induction switch group, and the controller receives the detection signals of the first induction switch 100 and the second induction switch 200 respectively, obtains the position information of the detection plate 400, and performs verification, thereby realizing the detection and verification of the operating position of the crane. Specifically, when the crane drives the first induction switch 100 and the second induction switch 200 to move along the length direction of the track beam, the first induction switch 100 and the second induction switch 200 will successively sense and leave the detection plate 400. The controller determines the moving direction of the first induction switch 100 and the second induction switch 200, that is, the moving direction of the crane, according to the order of receiving the detection level signals of the first induction switch 100 and the second induction switch 200. The controller performs encoding processing according to the moving direction and in combination with the received detection level signals of the first induction switch 100 and the second induction switch 200 to realize the detection of the position of the detection plate 400. It is worth noting that the controller in this embodiment has a power-off saving function to realize the timely saving of the current detection position information.
[0040] According to a crane operation position detection and verification device according to an embodiment of the present invention, the induction switch group is installed on the crane through a fixing frame, the first induction switch 100 and the second induction switch 200 are arranged on the upper end surface of the fixing frame, and the induction end surfaces of the first induction switch 100 and the second induction switch 200 are located in the same horizontal plane. It can be understood that the induction switch group is installed on the crane through the fixing frame to ensure the stability of the induction switch group and prevent shaking during movement, which affects the accuracy of the detection result.
[0041] Specifically, Figure 1 and Figure 2 As shown, the fixing frame includes a longitudinal fixing plate 310 and a transverse fixing plate 320. The lower end of the longitudinal fixing plate 310 is fixed on the crane, and the transverse fixing plate 320 is arranged horizontally. The bottom side of the transverse fixing plate 320 is fixed to the upper end of the longitudinal fixing plate 310. The induction switch group is installed on the upper side of the transverse fixing plate 320, that is, the first induction switch 100 and the second induction switch 200 are installed on the upper end surface of the transverse fixing plate 320 to ensure stability. In order to ensure the accuracy of the detection, the detection end surfaces of the first induction switch 100 and the second induction switch 200 are located at the same horizontal height, that is, the vertical distance between the first induction switch 100 and the second induction switch 200 and the same detection plate 400 is ensured to be the same. It is worth noting that the size of the transverse fixing plate 320 needs to ensure that the installation spacing between the first induction switch 100 and the second induction switch 200 will not cause electromagnetic interference.
[0042] According to a crane operation position detection and verification device according to an embodiment of the present invention, the detection plate 400 is installed on a reserved installation foundation on one side of the crane operation track through a bracket group, and the detection plate 400 is arranged opposite to the sensing end faces of the first induction switch 100 and the second induction switch 200. It can be understood that the detection plate 400 is fixedly installed on the upper side of the track beam through the bracket group and is kept horizontally fixed so that the bottom side of the detection plate 400 is arranged opposite to the sensing end faces of the first induction switch 100 and the second induction switch 200. In this embodiment, the reserved installation foundation on one side of the crane operation track is a workshop column, which is used to support the top steel structure of the workshop. The detection plate 400 is fixedly installed on the workshop column through the bracket group to achieve stable installation in a limited space.
[0043] Specifically, the detection plate 400 is relatively fixed to the track beam, and the crane drives the first induction switch 100 and the second induction switch 200 to move on the track beam. When the first induction switch 100 and the second induction switch 200 move to the bottom of the detection plate 400, the first induction switch 100 and the second induction switch 200 are respectively inductively sensed by the detection plate 400 to achieve detection.
[0044] According to a crane operation position detection and verification device according to an embodiment of the present invention, the bracket group includes a first bracket 520 and a second bracket 510, the first bracket 520 is arranged horizontally, and the second bracket 510 is arranged vertically, one end of the first bracket 520 is connected to a reserved installation foundation on one side of the crane operation track, the other end of the first bracket 520 is connected to one end of the second bracket 510, and the other end of the second bracket 510 is connected to the detection plate 400. It can be understood that the bracket group includes a first bracket 520 arranged horizontally and a second bracket 510 arranged vertically. In this embodiment, one end of the first bracket 520 is fixed to a workshop column, the other end of the first bracket 520 is connected to the upper end of the second bracket 510, and the lower end of the second bracket 510 is fixedly connected to the detection plate 400, as shown in FIG. Figure 2 As shown, the plane where the detection plate 400 is located is perpendicular to the second bracket 510 and parallel to the first bracket 520, so that the detection plate 400 is fixed at a set height above the track beam.
[0045] According to a crane operation position detection and verification device according to an embodiment of the present invention, a first adjustment slot 521 arranged transversely is provided on the first bracket 520, a second adjustment slot 511 and a third adjustment slot 512 arranged longitudinally and parallelly are provided on the second bracket 510, and a first bolt 530 adapted to the second adjustment slot 511 and a second bolt 560 adapted to the third adjustment slot 512 are passed through the first adjustment slot 521. It can be understood that the first adjustment slot 521 arranged transversely is provided on the first bracket 520, that is, the first adjustment slot 521 is arranged along the length direction of the first bracket 520. The second adjustment slot 511 and the third adjustment slot 512 arranged longitudinally and parallelly are provided on the second bracket 510, that is, the second adjustment slot 511 and the third adjustment slot 512 are both arranged along the length direction of the second bracket 510 and are parallel.
[0046] Furthermore, the first bolt 530 passes through the first adjustment slot 521 and the second adjustment slot 511 in sequence and then tightens the first nut 540, and the second bolt 560 passes through the first adjustment slot 521 and the third adjustment slot 512 in sequence and then tightens the second nut, so as to realize the connection between the first bracket 520 and the second bracket 510, and then realize the fixation of the detection plate 400. By adjusting the position of the first bolt 530 and the second bolt 560 in the first adjustment slot 521, the horizontal position of the detection plate 400 is adjusted; by adjusting the position of the first bolt 530 in the second adjustment slot 511 and the position of the second bolt 560 in the third adjustment slot 512 at the same time, the vertical height of the detection plate 400 is adjusted, so as to ensure that each detection plate 400 is on the same height plane and horizontal straight line, and improve the accuracy of detection.
[0047] It is worth mentioning that in order to ensure the tightness of the first bolt 530 and the first nut 540, a first washer 550 is sleeved on the first bolt 530, and in order to ensure the tightness of the second bolt 560 and the second nut, a second washer is sleeved on the second bolt 560 to ensure the stability of the connection between the first bracket 520 and the second bracket 510.
[0048] According to a crane operation position detection and verification device according to an embodiment of the present invention, the first induction switch 100 and the second induction switch 200 are both non-contact induction switches. It can be understood that by adopting non-contact induction switches, the sensitivity and accuracy of the detection process are increased, space is saved, and the position of the detection board 400 is conveniently arranged.
[0049] The following is a description of a crane operating position detection and verification method provided by an embodiment of the present invention. The crane operating position detection and verification method described below and the crane operating position detection and verification device described above can refer to each other.
[0050] like Figure 3 and Figure 4As shown, the embodiment of the present invention also provides a crane operation position detection and verification device method, comprising the following steps:
[0051] The position information of each detection plate 400 is input into the controller in advance, and the position coding information is initialized in the crane starting position controller;
[0052] The driving crane drives the induction switch group to move to the detection position corresponding to the detection plate 400 along the length direction of the track beam;
[0053] The controller collects the detection level signals output by the first induction switch 100 and the second induction switch 200 in real time, and then calculates the position encoder information of the detected detection board 400 according to the order of the level signals and the position encoding information before the level signals change;
[0054] The position information of the detection plate 400 pre-input into the controller is verified with the position information of the crane detected by the continuous position detection element of the crane to obtain the verification result and make corrections.
[0055] It is worth noting that the detection element of the crane is an encoder installed on the central axis of the crane wheel and rotates with the wheel, which records the number of rotations of the wheel in real time, thereby realizing the detection of the continuous position of the crane. The detection element can also use a barcode position detection component to realize the continuous position detection of the crane and obtain the position information of the crane.
[0056] That is to say, by pre-inputting the position information of each detection plate 400 into the controller as a verification standard, when the first sensing switch 100 and the second sensing switch 200 detect the detection plate 400, a detection level signal is sent to the controller, and the controller issues a verification instruction to compare and verify the detected distance information of the detection plate 400 with the moving distance detected by the detection element of the crane, and obtain the verification result and make corrections.
[0057] The detection and verification method according to an embodiment of the present invention further includes the following steps:
[0058] The controller judges the verification result and the error range and outputs the processing instruction.
[0059] The embodiment of the present invention provides a crane operation position detection and verification device method, and the specific steps are as follows:
[0060] It should be noted that in this embodiment, the sensing level signal of the first sensing switch 100 is set to sensing signal 1, the sensing level signal of the second sensing switch 200 is set to sensing signal 2, the direction from the first end to the second end of the track beam is the direction of increasing position, and the direction from the second end to the first end of the track beam is the direction of decreasing position.
[0061] S1, input the actual position information of each detection plate 400 into the controller in advance as a verification reference;
[0062] S2, when the crane is located at the first end of the track beam, that is, the initial position, the detection value of the controller is initialized and set, and the initial detection value A=0, the position increase signal F=0, the position decrease signal B=0, and the detection plate 400 in place signal M=0;
[0063] S3, driving the crane to move from the first end to the second end of the track beam, that is, in the direction of increasing position, when the first induction switch 100 has not moved to the bottom of the detection plate 400, the first induction switch 100 and the second induction switch 200 do not send out a detection level signal, and at this time, the signal data in the controller do not change;
[0064] S4, when the first induction switch 100 moves to the bottom of the detection plate 400, and the second induction switch 200 does not move to the bottom of the detection plate 400, the controller generates a position increase signal F=1, a position decrease signal B=0, a detection plate 400 in-position signal M=0, and a detection value A=0;
[0065] S5, when the first induction switch 100 moves to the bottom of the detection plate 400, the second induction switch 200 just moves to the bottom of the detection plate 400, that is, the moment when the detection level signal of the second induction switch 200 changes, the controller generates a detection value A=1, a detection plate 400 in-position signal M=1, a position increase signal F=0, and a position decrease signal B=0;
[0066] S6, when the first induction switch 100 and the second induction switch 200 are both located below the detection plate 400, the first induction switch 100 and the second induction switch 200 both output detection level signals, and the controller generates a detection value A=1, a detection plate 400 in-position signal M=1, a position increase signal F=0, and a position decrease signal B=0;
[0067] S7, when the first induction switch 100 leaves the detection plate 400, its detection level signal disappears. At this time, the second induction switch 200 is still under the detection plate 400, and the controller generates a detection value A=2, a detection plate 400 in-position signal M=0, a position increase signal F=0, and a position decrease signal B=0;
[0068] S8, after the first induction switch 100 leaves the bottom of the detection plate 400, the second induction switch 200 leaves the bottom of the detection plate 400, and the controller generates a detection value A=x+2a (where x is the detection value of a certain area, and a is a natural number), the detection plate 400 is in position signal M=0, the position increase signal F=0, and the position decrease signal B=0; in this embodiment, a=1;
[0069] S9, when the crane is located at the second end of the track beam, that is, the end position, the detection value of the controller is initialized and set to the initial detection value A=0, the position increase signal F=0, the position decrease signal B=0, and the detection plate 400 in place signal M=0;
[0070] S10, driving the crane to move from the second end to the first end of the track beam, that is, in the direction of decreasing position, when the second induction switch 200 has not moved below the detection plate 400, the second induction switch 200 and the first induction switch 100 do not send out a detection level signal, and at this time, the signal data in the controller do not change;
[0071] S11, when the second induction switch 200 moves to the bottom of the detection plate 400, and the first induction switch 100 does not move to the bottom of the detection plate 400, the controller generates a position increase signal F=0, a position decrease signal B=1, a detection plate 400 in-position signal M=0, and a detection value A=y (y is the detection value of a certain area);
[0072] S12, when the second induction switch 200 moves to the bottom of the detection plate 400, the first induction switch 100 just moves to the bottom of the detection plate 400, that is, the moment when the detection level signal of the first induction switch 100 changes, the controller generates a detection value A=y-1, a detection plate 400 in-position signal M=1, a position increase signal F=0, and a position decrease signal B=0;
[0073] S13, when the first induction switch 100 and the second induction switch 200 are both located below the detection plate 400, the first induction switch 100 and the second induction switch 200 both output detection level signals, and the controller generates a detection value A=y-1, a detection plate 400 in-position signal M=1, a position increase signal F=0, and a position decrease signal B=0;
[0074] S14, when the second induction switch 200 leaves the detection plate 400, its detection level signal disappears. At this time, the first induction switch 100 is still below the detection plate 400, and the controller generates a detection value A=y-2, a detection plate 400 in-position signal M=0, a position increase signal F=0, and a position decrease signal B=0;
[0075] S15, after the second induction switch 200 leaves the detection plate 400, the first induction switch 100 leaves the detection plate 400, and the controller generates a detection value A=y-2, a detection plate 400 in-position signal M=0, a position increase signal F=0, and a position decrease signal B=0;
[0076] S16. According to the above detection step rules, when the first induction switch 100 and the second induction switch 200 enter the nth (n is a continuous natural number starting from 1) detection plate 400, the controller generates a detection value A=(2×n-1); the non-detection area value A=(2×n-2) in front of the nth detection plate 400;
[0077] S17. After the controller calculates the position of the detection plate 400 according to the above detection step rules, it verifies the preset actual position information of each detection plate 400 with the currently received detection position information. If the error is within a reasonable range, the error correction is performed so that there is no significant data deviation when the detection position information runs between two detection plates 400; if the error exceeds the reasonable range, an alarm message is issued to indicate that the position detection system is abnormal. Among them, if the error is less than 0.1L (L is the average spacing between adjacent detection plates 400) and greater than S (the length of the detection plate 400), the crane position is corrected according to the preset information; if the error exceeds the above range, an alarm message is issued to indicate that the position detection system is abnormal.
