[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] <Overall Configuration> FIG. 1 is an external side view of a crane 100 with an electric hoist according to a first embodiment.

[0012] The electric hoist crane 100 is installed in a building. As shown in FIG. 1 , the electric hoist crane 100 includes a girder 10, a first traveling rail 11, an electric hoist 16, a crane saddle 20, a structure 40, and a recovery unit 60. In the following description, as shown in FIG. 1 , the direction in which the girder 10, which will be described in detail later, extends is referred to as the X direction. Furthermore, the direction in which the first traveling rail 11, which will be described in detail later, extends, and which intersects (is perpendicular to) the X direction, is referred to as the Y direction. The direction that intersects (is perpendicular to) the X direction and the Y direction is referred to as the Z direction.

[0013] <First traveling rail 11> The first traveling rail 11 is provided on a structural body such as a pillar of a building. The first traveling rail 11 is composed of a pair of first traveling rails 11a and 11b arranged opposite each other inside the building. The first traveling rails 11a and 11b extend parallel or approximately parallel to each other in the Y direction.

[0014] <Crane saddle 20> The crane saddle 20 is provided so as to be able to travel on the first traveling rail 11. Specifically, the crane saddle 20 is composed of a crane saddle 20a provided so as to be able to travel on the first traveling rail 11a, and a crane saddle 20b provided so as to be able to travel on the first traveling rail 11b.

[0015] That is, the pair of crane saddles 20a, 20b are arranged so as to be able to travel on the pair of first traveling rails 11a, 11b. This allows the crane saddle 20 to travel along the Y direction, which is the direction in which the first traveling rails 11 extend. The traveling operation of the crane saddle 20 is controlled by a traveling inverter device 12. The traveling inverter device 12 is provided on the girder 10, which will be described later.

[0016] The crane saddle 20a includes a saddle frame 21a and a first traveling mechanism 121a. The saddle frame 21a has a long side extending along the Y direction. The saddle frame 21a supports the first traveling mechanism 121a.

[0017] The first traveling mechanism 121a includes a driving wheel 25a and a driven wheel 26a mounted on the first traveling rail 11b, and an electric motor that rotates the driving wheel 25a. The driving wheel 25a is rotatably supported by an axle 27a near one end of the saddle frame 21a in the Y direction.

[0018] The running driven wheel 26a is rotatably supported via an axle 28a near the other end of the saddle frame 21a in the Y direction. In the following description, the side in the Y direction where the running driven wheel 26a is provided is referred to as the +Y side, and the side where the running drive wheel 25a is provided is referred to as the -Y side.

[0019] The crane saddle 20b includes a saddle frame 21b and a first traveling mechanism 121b. The saddle frame 21b has a long side extending along the Y direction. The saddle frame 21b supports the first traveling mechanism 121b.

[0020] The first traveling mechanism 121b has a traveling drive wheel 25b and a traveling driven wheel 26b installed on the first traveling rail 11b, and an electric motor (motor) that rotates and drives the traveling drive wheel 25b. The traveling drive wheel 25b is rotatably supported via an axle 27b near the end of the saddle frame 21b on the negative side in the Y direction. The traveling driven wheel 26b is rotatably supported via an axle 28b near the end of the saddle frame 21b on the positive side in the Y direction.

[0021] <Girder 10> The girder 10 extends in a direction intersecting the Y direction in which the first traveling rail 11 extends, i.e., in the X direction. The girder 10 is connected to the crane saddle 20a at one end in the X direction and to the crane saddle 20b at the other end in the X direction. Because the girder 10 is connected to the crane saddle 20, the girder 10 is arranged to be movable along the Y direction in which the first traveling rail 11 extends.

[0022] In the following description, the side of the X direction where the crane saddle 20a is provided is referred to as the positive X side, and the side where the crane saddle 20b is provided is referred to as the negative X side.

[0023] The girder 10 is provided with a traveling inverter device 12, a second traveling rail 13, and a structure 40. An electric hoist 16 is also provided on the girder 10 so as to be able to travel on the second traveling rail 13. That is, the structure 40 includes the electric hoist 16. The girder 10 is connected to the electric hoist 16.

[0024] <Second traveling rail 13> The second traveling rail 13 is a rail along which an electric hoist 16 (described later) travels, and is connected to the girder 10. The second traveling rail 13 is composed of second traveling rails 13a, 13b that are arranged opposite each other in a pair on the girder 10. The second traveling rails 13a, 13b extend parallel or approximately parallel to each other in the X direction.

[0025] <Traveling inverter device 12> The traveling inverter device 12 controls the movement of the crane saddle 20 described above. Specifically, the traveling inverter device 12 outputs drive signals that indicate the direction and amount of rotation of the electric motors of the first traveling mechanisms 121a, 121b, based on control signals output from the operation input device 3 of the electric hoist 16 described below. This causes the traveling drive wheels 25a, 25b to rotate, and the crane saddle 20 moves to the + side in the Y direction or the - side in the Y direction on the first traveling rail 11. As the crane saddle 20 moves, the girder 10 connected to the crane saddle 20 moves to the + side in the Y direction or the - side in the Y direction.

[0026] 1 shows the case where the traveling inverter device 12 is disposed on the wall surface on the +Y direction side of the girder 10. However, the traveling inverter device 12 is not limited to being disposed in the position shown in the figure, and may be disposed on the wall surface on the +Y direction side of the girder 10, for example.

[0027] <Structure 40> The structure 40 is provided on the above-described girder 10. The structure 40 includes the electric hoist 16, a walkway 51, and a handrail 52.

[0028] <Electric hoist 16> As described above, the electric hoist 16 is disposed on the girder 10. Therefore, the electric hoist 16 can move in the Y direction together with the girder 10 in response to movement of the girder 10 along the Y direction. In addition, the electric hoist 16 can move relatively in the X direction on the second traveling rail 13.

[0029] The electric hoist 16 includes a hoist 1, an operation input device 3, a crane hook 4, a hoist control unit 5, and a hoist frame 6. The hoist 1 is mounted on the hoist frame 6. The hoist 1 includes, for example, an electric motor, a reducer, and a drum around which a wire rope is wound. One end of the wire rope is provided with a crane hook 4 for suspending a load.

[0030] The hoist frame 6 supports second traveling mechanisms 2a and 2b that cause the electric hoist 16 to travel on the second traveling rail 13. The second traveling mechanism 2a has a traveling drive wheel 14a arranged on the second traveling rail 13a, a traveling drive wheel 14b arranged on the second traveling rail 13b, and an electric motor that rotationally drives the traveling drive wheels 14a and 14b.

[0031] The traveling drive wheels 14a, 14b are rotatably supported on the hoist frame 6 via an axle 17a on the negative side in the X direction. The traveling drive wheels 14a, 14b are rotationally driven by an electric motor mounted on the hoist frame 6.

[0032] The second traveling mechanism 2b has a traveling driven wheel 15a arranged on the second traveling rail 13a and a traveling driven wheel 15b arranged on the second traveling rail 13b. The traveling driven wheels 15a and 15b are rotatably supported on the hoist frame 6 via an axle 17b on the positive side in the X direction.

[0033] As a result, when the second running mechanisms 2a, 2b move on the second running rail 13, the hoist frame 6 supporting the second running mechanisms 2a, 2b and the hoist 1 mounted on the hoist frame 6 can move along the X direction.

[0034] The hoist control unit 5 controls the operation of the hoist 1 and the second traveling mechanisms 2a, 2b in response to an operator's operation of the operation input device 3. Specifically, the hoist control unit 5 outputs a drive signal that indicates the direction and amount of rotation of the electric motor of the first traveling mechanism 2a in response to the operation of the operation input device 3. This causes the traveling drive wheels 14a, 14b to rotate, and the electric hoist 16 moves on the second traveling rail 13 in the +X direction or the -X direction.

[0035] The operation input device 3 accepts operations by an operator to operate the crane with electric hoist 100. The operation input device 3 outputs a control signal to the hoist control unit 5 or the traveling inverter device 12 in accordance with the operation performed by the operator. The operations that can be controlled by the operation input device 3 include movement of the crane hook 4 and the suspended load along the Z direction, movement along the Y direction, and movement along the Z direction. In the Z direction, the side where the crane hook 4 approaches the hoist 1 is the +Z side, and the side where the crane hook 4 moves away from the hoist 1 is the -Z side.

[0036] The operation of the crane 100 with electric hoist in response to the operation input device 3 is as follows.

[0037] When the operator operates to move along the X direction, the operation input device 3 outputs a control signal to the hoisting machine control unit 5. Based on the input control signal, the hoisting machine control unit 5 causes the second traveling mechanisms 2a, 2b to travel on the second traveling rail 13 toward the +X side or the -X side in the X direction. As a result, the hoisting machine 1 moves together with the second traveling mechanisms 2a, 2b toward the +X side or the -X side in the X direction, and therefore the crane hook 4 and the suspended load move toward the +X side or the -X side in the X direction.

[0038] When the operator operates to move along the Y direction, the operation input device 3 outputs a control signal to the traveling inverter device 12. Based on the input control signal, the traveling inverter device 12 causes the first traveling mechanisms 121a, 121b of the crane saddle 20 to travel on the first traveling rails 11 toward the + side in the Y direction or the - side in the Y direction. As a result, the girder 10 connected to the crane saddle 20 and the electric hoist 16 arranged on the girder 10 move toward the + side in the Y direction or the - side in the Y direction. As a result, the crane hook 4 and the suspended load move toward the + side in the Y direction or the - side in the Y direction.

[0039] When the operator operates to move along the Z direction, the operation input device 3 outputs a control signal to the hoist control unit 5. The hoist control unit 5 drives the electric motor of the hoist 1 based on the input control signal. This causes the drum of the hoist 1 to rotate, and the wire hook attached to the drum is wound up or let out, so that the crane hook 4 and the suspended load move to the + side or - side in the Z direction. In other words, the load (suspended load) is moved up and down by the electric hoist 16.

[0040] 4, when an operator inputs a predetermined instruction from the operation input device 3, the traveling inverter control unit 34 stored in the traveling inverter device 12 controls the traveling inverter 35. The frequency, voltage, and current required for control are applied from the traveling inverter 35 to the traveling electric motors 47a, 47b, and at the same time, the traveling brakes 48a, 48b are controlled to be released, thereby moving the electric hoist 16 in the X direction and the −X direction along the girder 10.

[0041] Operation information for the electric hoist-equipped crane 100 in the X direction, −X direction, Z direction, and −Z direction is stored in the hoisting / traversing inverter control unit 31, and information for the Y direction and −Y direction is stored in the traveling inverter control unit 34. A cloud communication unit 37 is provided so that the operation information for the X direction, −X direction, Z direction, −Z direction, Y direction, and −Y direction can be acquired and edited at a remote location without the need to go to the locations where the hoisting / traversing inverter control unit 31 and the traveling inverter control unit 34 are installed.

[0042] The cloud communication unit 37 acquires information about operation in the X direction, −X direction, Z direction, and −Z direction from the hoisting / traversing inverter control unit 31. Furthermore, operation information about the Y direction and −Y direction is sent from the traveling inverter control unit 34 to the hoisting / traversing inverter control unit 31 via the communication path 36.

[0043] The cloud communication unit 37 also acquires operation information for the Y direction and the −Y direction from the hoisting / traversing inverter control unit 31. The cloud communication unit 37 transmits the operation information for the X direction, −X direction, Z direction, −Z direction, Y direction, and −Y direction to a cloud server 38, which is a computer, via the Internet communication network 42.

[0044] Cloud server 38 stores operation information for the X direction, −X direction, Z direction, −Z direction, Y direction, and −Y direction, and transmits the information from server 38 to display terminal 41 when a request is received from display terminal 41. The operation information includes the movement speed and operation time of electric hoist-equipped crane 100 in the X direction, −X direction, Y direction, and −Y direction.

[0045] Here, the information to be displayed on the display terminal 41 may be transmitted directly from the communication unit 37 to the display terminal 41 using short-range communication such as Bluetooth or Wi-Fi, without going through the Internet communication network 42. Examples of the display terminal 41 include a tablet terminal, a mobile phone (smartphone), a PC, etc.

[0046] The hoisting / traversing inverter device 31, the traveling inverter device 12, the cloud server 38, and the display terminal 41 may each be configured with hardware and software that includes a processing device such as a processor and a memory unit that stores programs, and the processing device reads and executes the programs to realize various functions.

[0047] <Walkway 51> The walkway 51 is a passageway that workers walk on when performing maintenance, inspection, etc. on the electric hoist 16. The walkway 51 is arranged along the side wall surface of the girder 10. Therefore, the walkway 51 extends along the X direction. In the Y direction, the walkway 51 only needs to have a width that allows workers to pass through. Note that the example shown in Figure 1 shows a case where the walkway 51 is provided on the side wall surface on the negative side in the Y direction of the girder 10.

[0048] <Handrail 52> The handrail 52 is provided on the walkway 51 to prevent workers from falling, etc. The handrail 52 is provided along the X direction in the Y direction (width direction of the walkway 51) on the side of the walkway 51 that is not in contact with the girder 10 (i.e., the negative side in the Y direction).

[0049] The handrail 52 has multiple support posts 521 and a beam 522. The multiple support posts 521 extend from the upper surface (the surface on the positive side in the Z direction) of the walkway 51 to the positive side in the Z direction. The multiple support posts 521 are arranged at predetermined intervals along the X direction near the end of the walkway 51 on the negative side in the Y direction. The beam 522 extends in the X direction and is fixed to bridge over the upper ends (the ends on the positive side in the Z direction) of each of the multiple support posts 521. The length from the surface on the positive side in the Z direction of the walkway 51 to the beam 522, i.e., the height of the handrail 52 in the Z direction, is, for example, 90 cm or more. A collection unit 60, which will be described in detail below, is provided on the handrail 52.

[0050] <Collection unit 60> The collection unit 60 is fixed to the handrail 52, which is the structure 40. The collection unit 60 collects CO contained in the atmosphere around the electric hoist crane 100. ２ As shown in Fig. 1, the plurality of collection units 60 are provided in a range R1 along the X direction in which the handrail 52 extends. Note that the plurality of collection units 60 are not limited to being provided over the entire range R1 shown in Fig. 1, but may be provided in a part of the range R1. Alternatively, one collection unit 60 may be provided in the range R1 of the handrail 52.

[0051] The range R1 to which the recovery unit 60 is fixed is a rectangular surface with its long sides aligned in the X direction and its short sides aligned in the Z direction, intersecting (orthogonal to) the Y direction. Therefore, the range R1 is located on the flow path of the airflow generated when the crane saddle 20 travels on the first traveling rail 11 and the electric hoist crane 100 moves along the Y direction. In other words, the recovery unit 60 is disposed on the flow path of the airflow generated by the travel of the crane saddle 20.

[0052] 1, the collection unit 60 is disposed on the negative side in the Y direction with respect to the walkway 51 and the handrail 52, that is, on the outside of the walkway 51 and the handrail 52. As described above, the collection unit 60 disposed on the handrail 52 collects CO ２ Adsorbent 50 and CO ２ and a case 63 that detachably supports the adsorbent 50 .

[0053] <CO ２ Adsorbent 50> CO ２ The adsorbent 50 is housed in a case 53 and fixed to a handrail 52. ２ The adsorbent 50 is a filter-like material in which powdered or granular adsorbent material is sealed in a breathable pack, and absorbs CO contained in the surrounding air. ２ It absorbs and stores (adsorbs)

[0054] CO ２ One example of the adsorbent material for the adsorbent 50 is a material that performs physical adsorption using zeolite or activated carbon, which are currently mainstream materials for recovering and separating carbon dioxide. Other examples of adsorbent materials include those that perform chemical adsorption and absorption using amine-supported inorganic porous bodies, supported activated carbon, etc., and chemical absorption carbonate systems such as Ca looping. However, CO ２ The adsorption substance and adsorption method of the adsorbent 50 are not limited to those described above.

[0055] <CO ２ Calculation of the adsorption amount of the adsorbent 50> On the display terminal 41, ２ Adsorption amount 50 CO ２ The adsorption rate and amount are displayed. If the next inspection date for either or both of the annual inspection and monthly inspection is approaching, the remaining number of days for adsorption and an icon to warn the user may be displayed on the tab.

[0056] Also, the previous CO ２ The implementation date of the adsorbent replacement and the predicted date of the next replacement are updated when the replacement is performed. The replacement completion date is displayed as the date saved in the cloud server 38 when the check box is pressed at the time of replacement. ２ The capacity rate of the adsorption amount is reset to 0%.

[0057] CO２ CO by the adsorbent 50 ２ The adsorption amount of CO2 is calculated by the formula: ２ Adsorption amount (gCO ２ / unit) = installation volume (m ３ )×adsorbent density (kg / m ３ ) × adsorption rate (gCO2 / kg / h) × operating time (h).

[0058] Installation volume (m ３ ) and adsorbent density (kg / m ３ ) is a CO mounted on the electric hoist crane 100 ２ The installation volume of the adsorbent 50 and the CO ２ The density value of the adsorbent 50 is input and stored in the calculation item field at any time, and the input value is called up and used during calculation.

[0059] The adsorption rate (gCO2 / kg / h) and operating time (h) are calculated using the movement speeds and operating time in the X direction, -X direction, Y direction, and -Y direction of the crane 100 with electric hoisting machine, which are transmitted by the cloud server 38 when a request is received from the display terminal 41. ２ CO by the adsorbent 50 ２ Calculate the amount of adsorption.

[0060] According to the above-described first embodiment, the following effects can be obtained.

[0061] The crane 100 with an electric hoist comprises a structure 40 including an electric hoist 16 for moving a load up and down, a girder 10 on which the structure 40 is provided, and a CO 2 trap fixed to the structure 40. ２ The recovery unit 60 recovers CO contained in the surrounding atmosphere. ２ Absorbs and stores CO ２ The adsorbent 50 is included. This allows the CO 2 present in the atmosphere around the electric hoist crane 100 to be absorbed. ２ can be adsorbed.

[0062] <CO ２ Adsorbent 50 replacement service > CO ２ The adsorbent 50 is replaced by the user of the electric hoist crane 100 and the CO ２ The CO ２When the adsorption rate is reached, ２ An alert is displayed on a display terminal 41 owned by the exchanger of the adsorbent 50, and the adsorbent 50 is exchanged.

[0063] CO ２ The amount of the adsorbent 50 used is determined by the user of the electric hoist crane 100 and the CO ２ The CO displayed on the display terminal 41 for the period agreed upon in advance by the exchanger of the adsorbent 50 ２ The user is charged based on the amount of CO adsorption. ２ The charge based on the amount of adsorption is ２ Adsorption amount (gCO ２ / unit) and usage cost (¥ / gCO ２ ) and CO ２ The user of the electric hoist crane 100 is notified by the company that replaces the adsorbent 50.

[0064] Alternatively, a subscription system may be introduced, where the amount is a fixed amount every month or for any agreed period. In this case, multiple fee plans are set up for users to choose from. ２ The frequency of replacement of the adsorbent 50 and the CO ２ Adsorption rate and CO ２ The fee is set based on the installed volume of the adsorbent 50. ２ The cost includes the cost of the adsorbent 50 parts, shipping, replacement costs, and technical support costs for inquiries, making it possible for users to make predictable and affordable expenses.

[0065] <Effects of the First Embodiment> Since an electric motor is used for the electric hoist 16 and the crane saddle 20 to travel, the operation of the crane 100 with an electric hoist itself does not require CO2. ２ However, when electricity is supplied to the motor, CO is emitted at the power plant that supplies the electricity. ２ Therefore, the electric hoist crane 100 indirectly emits CO ２ It can also be said that

[0066] In the first embodiment, as described above, the CO ２ The amount of adsorption is displayed on the display terminal 41.２ The CO ２ The adsorbent 50 can be replaced. This allows the CO generated by the operation of the electric motor, i.e., the operation of the electric hoist crane 100, to be reduced. ２ This will reduce emissions, which will contribute to carbon neutrality and help curb global warming.

[0067] As described above, the crane 100 with an electric hoist of the first embodiment includes a pair of crane saddles 20a, 20b arranged to be able to travel on a pair of traveling rails (first traveling rails 11a, 11b), a girder 10 connecting the pair of crane saddles 20a, 20b, a lateral rail (second traveling rails 13a, 13b) arranged on the girder 10 in a direction substantially perpendicular to the traveling rails (first traveling rails 11a, 11b), an electric hoist 16 arranged to be able to travel laterally on the lateral rail (second traveling rails 13a, 13b), and a CO 2 trapping mechanism 16 fixed to a structure 40 provided on the crane 100 and contained in the surrounding atmosphere. ２ By directly absorbing and storing CO ２ CO2 recovery ２ The CO absorber 50 and the CO absorber 50 are pre-learned using the operation information of the crane 100. ２ Based on the adsorption amount estimation formula, ２ CO of the adsorbent 50 ２ and a learning device 70 (see FIG. 5) that estimates the amount of adsorption.

[0068] An example of the configuration of the learning device 70 is shown in FIG.

[0069] As shown in FIG. 5, the learning device 70 ２ a learning data storage unit 71 that stores learning data necessary for learning the adsorption amount estimation formula; and a CO ２ The adsorption amount estimation formula is learned and calculated. ２ Based on the adsorption amount estimation formula, ２ A learning calculation unit 72 that outputs the adsorption amount, and a CO ２ and a learning result storage unit 73 that stores the amount of adsorption.

[0070] Here, the structure 40 is configured to include a walkway 51 and a handrail 52. ２ The adsorbent 50 is fixed to a walkway 51 or a handrail 52. The learning device 70 calculates the CO ２ Estimate the amount of adsorption.

[0071] The learning device 70 is provided, for example, in the travel control unit (travel inverter control unit 34) of the crane saddles 20a, 20b.

[0072] The learning device 70 ２ The installation volume of the adsorbent 50 and the CO ２ The density of the adsorbent 50 and the CO ２ The adsorption rate of the adsorbent 50 and the operating time of the crane 100 are used to calculate the CO ２ The learning device 70 estimates the amount of CO ２ The adsorption speed of the adsorbent 50 is calculated by using the rotation speed of the electric hoist 16, the diameter of the driving wheel, and the reduction ratio of the reduction gear. ２ The learning device 70 estimates the operating time of the crane 100 based on the CO ２ The time is estimated from the rotation time of the electric hoist 16 for each moving speed of the adsorbent 50.

[0073] The crane 100 is ２ The crane 100 has a display unit that displays the amount of suction. The display unit is provided in, for example, at least one of the input device 3 that accepts operations for operating the crane 100, the travel control unit (travel inverter control unit 34) of the crane saddles 20a, 20b, and the traverse control unit (hoisting / traverse inverter control unit 31) of the electric hoisting machine 16.

[0074] The inspection assistance system for the crane 100 with an electric hoist has a server 38 that communicates with the crane 100 and has a learning device 70. The crane 100 transmits operation information of the crane 100 to the server 38, and the learning device 70 of the server 38 uses the operation information to ２ Estimate the amount of adsorption.
