Description

The present invention relates to a crane device and an operation management system for the crane device.

Periodic inspections of crane equipment are required by law, but at the time of inspection, instructions for parts replacement and suggestions for improvement of usage are inspected, taking into account the consumption status of the components of the crane equipment, operation information, etc. Is doing to the operator. Since the manufacturer of the crane device has set a judgment standard for parts replacement, it is possible to make a clear judgment based on this judgment standard. On the other hand, regarding the improvement of the usage method, since it is necessary to analyze the operation information of the crane device, there is a tendency that individual differences (level differences) occur in the proposal contents depending on the knowledge and experience of the inspector.

In order to solve this problem, for example, the method described in Japanese Patent No. 6013974 (Patent Document 1) is known. In Patent Document 1, the remaining life of the crane device and its components is calculated from operation information and error information using remote communication, and for example, the cycle of inching (micro movement) operation is limited on the control device side. It regulates the operation of crane equipment such as control and control that reduces the operating speed of the crane equipment. By improving the control operation in this way, the parts replacement cycle can be extended, and the life of the crane device itself can be extended.

Japanese Patent No. 6013974

However, in Patent Document 1, although the life of the crane device is extended by restricting the control operation on the control device side, the proposal such as how to improve the usage method is not transmitted to the operator. Therefore, when the operator does not adopt the technique for regulating the control operation described in Patent Document 1 and operates a crane device having a short remaining life, the parts replacement cycle is extended by executing the same usage method as before. There may be problems such as not being able to contribute to improving the life of the crane equipment.

It is in the operation management system of the crane device provided with the display means for displaying at least one of the evaluated evaluation points and the total evaluation points.

The second feature of the present invention is a measuring means for measuring measurement values for predetermined evaluation items in the hoisting direction, traverse direction, and traveling direction of the crane device, and measurement values for each evaluation item from the measuring means. It is a crane device provided with a measurement item evaluation means for obtaining an evaluation point by comparing with a corresponding standard evaluation value and obtaining a total evaluation point from the evaluation points for each evaluation item in each of the hoisting direction, the traverse direction, and the traveling direction.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the following embodiments, and various modifications and applications are included in the technical concept of the present invention. Is also included in that range.

FIG. 1 shows the overall configuration of the inverter type crane device to which the present invention is applied, and FIG. 2 shows the configuration of the control unit of the inverter type crane device according to the embodiment of the present invention. The inverter type crane device used in the present embodiment is provided with a wire rope load measuring device, and is configured to be able to measure the load of the suspended load.

In FIG. 1, the inverter type crane device includes a crane hook 1, a wire rope 2, a hoisting induction motor 3, a hoisting drum 4, a traversing induction motor 5, a traversing wheel 6, a traversing girder 7, a traveling induction motor 8, and the like. It is composed of a traveling wheel 9, a traveling girder 10, a hoisting / traversing inverter control device 11, an operation input device 12 suspended from a cable, a traveling inverter control device 13, and the like. Further, the hoisting induction motor 3, the traverse induction motor 5, and the traveling induction motor 8 each have a built-in brake 14 for an induction motor (see FIG. 2).

In the inverter type crane device, the load attached to the crane hook 1 is wound / unwound by the hoisting drum 4 rotated by the hoisting induction motor 3 to wind up / down the wire rope 2 in the Y direction (Y direction, -Y direction). (Indicated by the arrow), that is, move the luggage up and down. Further, the traversing induction motor 5 rotates the traversing wheel 6 and moves in the X direction (indicated by arrows in the X direction and the −X direction) along the traversing girder 7. Further, the traveling induction motor 8 rotates the traveling wheel 9 and moves in the Z direction (indicated by arrows in the Z direction and the −Z direction) along the traveling girder 10.

As shown in FIG. 2, the hoisting / traversing inverter control device 11 includes a hoisting / traversing inverter control unit 15, a hoisting inverter 16, and a traversing inverter 17. Further, the traveling inverter control device 13 includes a traveling inverter control unit 18 and a traveling inverter 19. Further, the hoisting / traversing inverter control unit 15 and the traveling inverter control unit 18 are connected by a communication line 20.

The hoisting induction motor 3 and the traverse induction motor 5 are controlled by the hoisting / traversing inverter control unit 15 housed in the hoisting / traversing inverter control device 11. That is, when the operator inputs a predetermined instruction from the operation input device 12, the hoisting / traversing inverter control unit 15 controls the hoisting inverter 16 and the traversing inverter 17, so that the hoisting inverter 16 and the traversing inverter 16 are controlled. The control information necessary for control is given to 17.

Then, the hoisting inverter 16 and the traversing inverter 17 apply the frequencies, voltages, and currents required for the hoisting induction motor 3 and the traversing induction motor 5, and simultaneously open and control the induction motor brake 14. As a result, in the case of the hoisting drum 4, the load attached to the crane hook 1 is moved in the Y direction without falling, and in the case of the traversing wheel 6, it is used for traversing along the traversing girder 7. The wheel 6 is moved in the X direction.

Similarly, in the traveling induction motor 8 attached to the traveling wheel 9, when the operator inputs a predetermined instruction from the operation input device 12, the traveling inverter control unit 18 stored in the traveling inverter control device 13 causes the traveling inverter. By controlling 19 and applying the frequency, voltage, and current required for the traveling induction motor 8 to the traveling induction motor 8 and simultaneously opening and controlling the induction motor brake 14, the traveling wheel 9 is operated along the traveling girder 10. Move in the Z direction.

The above is a description of a normal crane device, and then a description of an embodiment of the present invention will be described. In the present embodiment, apart from the above-mentioned communication line 20, the hoisting / traversing inverter control unit 15 and the traveling inverter control unit 18 are connected by a communication line 21 for operation evaluation. Further, the hoisting / traversing inverter control device 11 is provided with a communication unit 22, and the communication unit 22 is connected to the hoisting / traversing inverter control unit 15 by a communication line 21 for operation evaluation.

The communication unit 22 is connected to the cloud network CLD by wireless communication, and the cloud network CLD is also connected to the display terminal 23 provided with the communication unit by wireless communication. Therefore, the communication unit 22 and the display terminal 23 are set in an environment in which they can access each other via the cloud network CLD. As the display terminal 23, a portable tablet terminal or a personal computer (PC) can be used. The display terminal 23 may be provided in the crane device.

Next, the operation evaluation control unit 24, which is a characteristic portion of the present embodiment, will be described with reference to FIG. In FIG. 3, the hoisting / traversing inverter control unit 15 includes an operation evaluation control unit 24. The operation evaluation control unit 24 actually expresses the function executed by the microcomputer constituting the hoisting / traversing inverter control unit 15 as a functional block. That is, the microcomputer executes various control functions by a control program, and this control function is regarded as a functional block. However, the operation evaluation control unit 24 may be independently provided in the crane device.

The operation evaluation control unit 24 includes an operation data input unit 25, and the operation data input unit 25 has at least a brake signal (Bsig), a motor current signal (Msig), and a switch signal (Ssig) of the operation input device 12. ), Power signal (Vsig), and load signal (Lsig) are input. Needless to say, it is possible to input an input signal other than these input signals.

The operation data input from the operation data input unit 25 can be used as necessary for the start frequency measurement unit 26, the load time rate measurement unit 27, the inching measurement unit 28, the power cutoff frequency measurement unit 29 during operation, and the load factor measurement unit 30. The necessary evaluation items are measured by the respective measuring units 26 to 30. These measurement operations are performed by a microcomputer control program. Each of the measured evaluation items is sequentially stored in the measurement item storage unit 31 with the passage of time. The measurement item storage unit 31 can store the measurement item using, for example, the RAM area of the microcomputer.

Each evaluation item stored in the measurement item storage unit 31 is evaluated by the measurement item evaluation unit 32, and this evaluation will be described later. When the evaluation is completed by the measurement item evaluation unit 32, the evaluation result is sent to the cloud network CLD by wireless communication, and further sent to the display terminal 23 by wireless communication. The display terminal 23 can be viewed by the operator, and the evaluation result can prompt the operator to improve the method of using the crane device, and the operator's driving skill can be improved.

Next, a specific example of the evaluation method of the operation evaluation control unit 24 will be described. In addition, in evaluating the operation of the crane device, various evaluation items are given for the operating direction (winding direction, traverse direction, traveling direction) of the crane device, but an example of the hoisting direction will be described below. .. Of course, the evaluation items may differ in the traverse direction and the traveling direction, but the driving evaluation can be performed by the same method as the method described below.

FIG. 4 shows the evaluation items in the hoisting direction of the crane device, the distribution of the evaluation points to the evaluation items, and the results of scoring from the measured values in the actual operation. The measured values are measured by the respective measuring units 26 to 30 shown in FIG. 3, and the scoring is evaluated by the measurement item evaluation unit 32 shown in FIG.

The evaluation items in the hoisting direction are start frequency (times / h), load time rate (% ED), inching (times / h), number of power cutoffs during operation (times / h), and load factor (K). .. Then, for each evaluation item, a standard evaluation point from 10 points to 20 points is set in increments of 2 points, and an evaluation standard range as a reference for comparison is set for each standard evaluation point.

For example, in terms of starting frequency (times / h), an evaluation standard range of "0 to 400" for 20 points, an evaluation standard range of "401 to 450" for 18 points, and "451 to" for 16 points. Evaluation standard range of "500", evaluation standard range of "501 to 550" for 14 points, evaluation standard range of "551 to 600" for 12 points, evaluation standard of "601 to 660" for 10 points The range is set. Therefore, the score is determined by which evaluation reference range the measured value belongs to. Since the other evaluation items are as shown in FIG. 4, the description thereof will be omitted.

Here, as described above, by setting the evaluation items individually for the traverse direction and the traveling direction in addition to the hoisting direction, it is possible to carry out the evaluation more realistically. Further, the evaluation items and points shown in FIG. 4 are examples, and it is desirable to determine the setting of another evaluation item, the increase / decrease in the number of evaluation items, the distribution of points, etc. according to the crane device. Further, the evaluation standard range may be changed later.

Next, a measurement method for each evaluation item shown in FIG. 4 will be described. The measurement method described below is an example, and may be measured by another measurement method.

First, the starting frequency (times / h) is the number of times the hoisting induction motor 3 is operated per hour, and is counted as one when the induction motor brake 14 is released and braked again. As shown in FIG. 5, the total count value in one minute is stored in the storage area for 60 pieces (corresponding to one hour) every minute.

For example, in FIG. 5 (t1), the total count value after the first 1 minute has elapsed is stored, in (t2), the total count value after the next 1 minute has elapsed, and in (t3), the next 1 minute has elapsed. After that, the total count value is stored, in (t4), the total count value after 58 minutes have passed, and in (t5), the total count value after the next 1 minute has passed, and this operation is repeated thereafter. become.

This storage area is a storage means such as a ring buffer, and when the start frequency is saved, the oldest measured value is overwritten with a new measured value, so that the latest 60-minute start frequency (measured value) is obtained. Can be memorized. The starting frequency (times / h) can be obtained by adding all the measured values for these 60 pieces. Up to this point, the processing is executed by the start frequency measuring unit 26 and the measurement item storage unit 31.

Returning to FIG. 4, since the starting frequency (times / h) this time is "452 times / h", it is determined to which range of the evaluation reference range set by the starting frequency belongs. This time, since it belongs to the range of "451 to 500", the evaluation point is determined to be "16". The determination of the evaluation point is a process executed by the measurement item evaluation unit 32.

Next, a method for measuring the load time rate (% ED) will be described. The load time rate (% ED) is the ratio of the time when the hoisting induction motor 3 is energized per hour, that is, the ratio of the operating time per hour, and the load time ratio (% ED) is also the start frequency (times / time / time). Similar to h), the load time rate (% ED) can be obtained by saving in the form shown in FIG. 5 and executing the operation shown in the following “Equation 1”.

For example, the measured value of the load time rate (% ED) this time is "33".

Then, returning to FIG. 4, since the load time rate (% ED) this time is "33 (% ED)", it is determined to which range of the evaluation reference range set by the load time rate belongs. This time, since it belongs to the range of "0 to 40", the evaluation point is determined to be "20". The determination of the evaluation point is a process executed by the measurement item evaluation unit 32.

The above-mentioned starting frequency and load time rate are the specifications of the crane equipment specified by each crane equipment manufacturer, and are set as evaluation items for confirming whether or not the crane equipment is used beyond the specifications. There is.

Next, a method of measuring inching will be described. Here, inching is a sizing operation, and the crane device tends to use inching frequently when lifting a suspended load or when landing. Excessive inching causes great damage to the components of the electromagnetic contactor, the relay contact, and the brake 14 for the induction motor, which causes an adverse effect such as shortening the life of the parts. Therefore, evaluation of inching is also important.

Inching (times / h) can be determined by measuring the number of starts in a short time. In the present embodiment, for example, as shown in FIG. 6, when the time from once braking by the brake to the next release is less than 1 second, the number of inchings is counted as one time. The number of inchings is obtained by totaling the number of inchings per minute, storing in the form shown in FIG. 5, and adding all 60 pieces of data to obtain the number of inchings. For example, the number of inchings this time is "182".

Then, returning to FIG. 4, since the current inching (times / h) is "182 (times / h)", it is determined to which range of the evaluation reference range set by the inching belongs. This time, since it belongs to the range of "181 to 200", the evaluation point is determined to be "10". The determination of the evaluation point is a process executed by the measurement item evaluation unit 32.

Next, a method for measuring the number of times the power is cut off during operation will be described. Here, if the power is cut off during operation, the swing of the suspended load may increase and the safety may be impaired, and the components of the brake 14 for the induction motor may be damaged, so that the life of the components may be shortened. It causes such an adverse effect. Even if the power supply to the crane device is cut off due to a momentary power failure or the like without instructing the operation input device 12 to shut off the power supply, the power supply to the hoisting / traversing inverter control unit 15 and the traveling inverter control unit 18 is cut off. Is given in the same manner as the instruction from the operation input device 12.

Regarding the number of power cutoffs (times / h) during operation, for example, while the induction motor brake 14 is released, a power cutoff instruction comes from the operation input device 12 to the hoisting / traversing inverter control unit 15 and the traveling inverter control unit 18. And count as one time. The number of power cuts during operation is calculated by totaling the number of power cuts during operation for one minute, and the number of power cuts during operation is calculated by saving in the form shown in FIG. 5 and adding all 60 data. Desired. For example, the number of times the power is cut off during the operation this time is "8".

Here, when the power supply is cut off, if the power supply to the hoisting / traversing inverter control unit 15 and the traveling inverter control unit 18 is immediately cut off, the control program does not function and the number of times the power supply is cut off cannot be counted. There is a fear.

However, in a general crane device, a driving power source for a microcomputer is generated and supplied via a smoothing capacitor mounted on a traversing inverter control unit 15 and a traveling inverter control unit 18, so that the power supply is cut off. However, the control program can be sufficiently functioned by the discharge time of the smoothing capacitor, and the time for counting the number of power cutoffs is guaranteed.

Then, returning to FIG. 4, since the number of power cutoffs (times / h) this time is "8 (times / h)", which range of the evaluation reference range set by the number of power cutoffs during operation belongs to. Judged. Since it belongs to the range of "7 to 8" this time, the evaluation score is determined to be "12". The determination of the evaluation point is a process executed by the measurement item evaluation unit 32.

Next, a method for measuring the load factor (K) will be described. The load factor can be calculated by the following "Equation 2".

Here, P1, P2, P3 ... Are the ratios of the load to the rated overload, and t1, t2, t3 ... Are the ratios of the usage time in each load to the total usage time.

For example, in a crane device with a rated overload of 1 ton, when the outward path is a 0.2 t hanger to carry a 0.4 t hanger and the return path is no load (0.2 t hanger) to return to the original position. When the load rating (K) is calculated using "Equation 2", it becomes the following "Equation 3".

Here, "0.2" is the mass of the hanging tool, "0.4" is the mass of the suspended load, and "0.5" is the ratio of the time related to the outward route and the return route. For example, the load factor (K) this time is about "0.48".

When calculating on the control program, for example, the mass of the suspended load is measured by the current value, and the measured load is no load (0% to 10%), light load (11% to 25%), medium load ( It is classified into 26% to 50%), heavy load (51% to 75%), super heavy load (76% to 100%), and overload (101% or more), and the operating time for each classified load is measured. The load factor (K) can be obtained by obtaining the operating time for one minute, storing the data in the form shown in FIG. 5, and calculating the data for 60 pieces using (Equation 2).

Then, returning to FIG. 4, since the load factor (K) this time is "0.48", it is determined which range of the evaluation reference range set by the load factor (K) belongs to. This time, since it belongs to the range of "0 to 0.65", the evaluation point is determined to be "20". The determination of the evaluation point is a process executed by the measurement item evaluation unit 32.

Then, the measurement item evaluation unit 32 totals the evaluation points of each evaluation item in the hoisting direction to obtain a comprehensive evaluation point. As shown in FIG. 4, the total evaluation point in the winding direction this time is "78". Similarly, evaluation points and comprehensive evaluation points are required for each evaluation item in the traverse direction and the traveling direction. As shown in FIG. 7, the overall evaluation point in the traverse direction is "85", and the overall evaluation point in the traveling direction is "92".

When the comprehensive evaluation points in the hoisting direction, the traverse direction, and the traveling direction are obtained, the measurement item evaluation unit 32 further obtains the overall comprehensive evaluation points for the crane device as a whole. This overall overall evaluation point is obtained as an average value obtained by adding the overall evaluation points in the hoisting direction, the traversing direction, and the traveling direction. The overall overall evaluation score this time is "85". The table showing the overall evaluation score in the hoisting direction, traverse direction, and traveling direction and the overall overall evaluation score shown in FIG. 7 is sent to the display terminal 23 as necessary. Is displayed on the display screen. As a result, the operator can know the operation evaluation of the entire crane device and the operation evaluation of the individual drive systems in the hoisting direction, the traversing direction, and the traveling direction. The evaluation points may be displayed as symbols instead of numerical values.

Further, the measurement item evaluation unit 32 is configured to create the operation evaluation shown in FIG. In FIG. 8, the measured value and the evaluation point are displayed for each evaluation item, and the relative evaluation comparing the current evaluation points with respect to the highest reference evaluation point is obtained and displayed. This makes it easier to understand the operations that need to be improved in the driving operation. For example, with respect to inching, since the relative evaluation is "10/20", it is possible to urge the operator that it is necessary to reduce the number of inching operations.

In this way, as shown in FIGS. 7 and 8, the measurement item evaluation unit 32 evaluates by comparing the measured values for each evaluation item from the respective measurement units 20 to 30 with the corresponding standard evaluation values. The points are obtained, the comprehensive evaluation points are obtained from the evaluation points for each evaluation item for each of the hoisting direction, the traversing direction, and the traveling direction, and at least one of the evaluation points and the comprehensive evaluation points is displayed on the display terminal. Of course, it goes without saying that the tables shown in FIGS. 7 and 8 can be displayed as they are.

Further, for example, by saving the measured values corresponding to each evaluation item every hour, a graph (starting frequency) as shown in FIG. 9 can be created and displayed. This graph can graph not only the start frequency but also the load time rate, the number of inchings, the number of power cutoffs, and the load factor. According to this, it becomes possible to clarify and supply the operator with information prompting the improvement of the driving operation such as which time zone the driving should be improved.

Here, the information related to the operation evaluation in FIG. 9 is stored in the hoisting / traversing inverter control unit 15 and the traveling inverter control unit 18, and further calculated and displayed, but the past data is sequentially saved. As the amount of data becomes enormous, as shown in Fig. 2, at least the measured values, evaluation points, and overall evaluation points are sent to the cloud server and stored by using the cloud network CLD. May be. Furthermore, it is also possible to send only the measured values and calculate and display the evaluation points and the overall evaluation points on the server.

That is, the hoisting / traversing inverter control unit 15 sends measurement data (measured values) and calculation data (evaluation points and comprehensive evaluation points) in the hoisting direction, traversing direction, and traveling direction to the communication unit 22, and the communication unit 22 sends them. The measured measurement data and calculation data that have been received are transmitted to the cloud network CLD. The cloud server stores measurement data and calculation data for the past month at 1-hour intervals.

Then, the stored measurement data and calculation data are displayed on the display screen of the display terminal 23 as shown in FIGS. 7, 8 and 9. The display of FIGS. 7, 8 and 9 is arbitrary, and the display terminal 23 can select and display a necessary table or graph.

Here, the communication unit 22 is not arranged only in the hoisting / traversing inverter control device 11, but as shown in FIG. 10, the communication unit 22A is arranged in the hoisting / traversing inverter control device 11 to control the traveling inverter. The communication unit 22B may be arranged in the device 18. The communication units 22A and 22B are connected to the cloud network CLD by wireless communication as in FIG. 2.

According to the present embodiment, it is possible to clearly propose information for urging the operator to improve the driving method. Further, when the operator uses another crane device, he / she learns the information for promoting the improvement of the operating method, so that the safety and efficiency of the operating operation can be improved. Furthermore, visualization (graphing) of information (measured values) related to operation evaluation clarifies the time zone in which operation is concentrated, so work efficiency can be improved by adding equipment or changing work processes. ..

For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Further, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment.
