[0021] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] In the related art, when workers are troubleshooting the electrolytic aluminum multifunctional overhead crane, mechanical crushing accidents are prone to occur on the crane's track, resulting in poor safety.
[0023] For the above situation, please see Figure 1 The present application proposes a crane 1 for an electrolysis workshop, comprising a main body 10, a first switch 20 and a first indicator 30. The electrolysis workshop can be divided into multiple working areas, and all electrolysis work in each working area is completed by a crane 1, so that the production of the electrolysis workshop can proceed in an orderly manner. The crane 1 can be used for shelling, adding alumina to the electrolytic cell, transporting electrolytic anodes, and transporting other heavy objects.
[0024] The main body 10 includes a transport member 11 and a circuit board, wherein the transport member 11 is electrically connected to the circuit board, and the circuit board is used to access an external power source. Specifically, the transport member 11 is used to carry and transport heavy objects, and the circuit board provides power for the movement of the transport member 11, wherein the external power source may be a factory-specific power source or a battery, etc.
[0025] The first switch 20 is connected to the circuit board, and the first switch 20 is used to control the on and off of the circuit board and the power supply, so the first switch 20 can disconnect the power supply of the main body 10, so that the transport member 11 on the main body 10 suspends operation; the first indicator 30 is electrically connected to the circuit board, and the first indicator 30 is used to indicate the start and stop of the transport member 11. When the transport member 11 is in an unpaused state, the first indicator 30 sends a first indication signal, and when the transport member 11 is in a closed state, the first indicator 30 can send a second indication signal.
[0026] Specifically, the control switch of the overhead crane 1 is generally arranged inside the workshop and is located at a position that is convenient for the staff to operate. The overhead crane 1 is generally in an on state. When the overhead crane 1 is needed for transportation, the movement direction of the overhead crane 1 can be further controlled. When the overhead crane 1 is not needed, the overhead crane 1 can be suspended at the original position. If a certain overhead crane 1 fails, the staff needs to go to the running track of the overhead crane 1 for inspection. At this time, the staff can turn off the corresponding first switch 20 at the running track, so that the corresponding transport member 11 is powered off to prevent the transport member 11 from moving suddenly.
[0027] It should be noted that, generally, a plurality of overhead cranes 1 are arranged in the electrolysis workshop, and each overhead crane 1 can move synchronously or individually. In the embodiment of the present application, a first switch 20 is arranged specifically for cutting off the power supply to the transport member 11. When an overhead crane 1 is performing troubleshooting, the first switch 20 can be closed so that the corresponding transport member 11 can be in a completely power-off state, thereby avoiding the synchronous movement of the transport member 11 with other transport members 11, that is, avoiding the sudden movement of the transport member 11, thereby improving the safety performance of the overhead crane 1 during maintenance; at the same time, the embodiment of the present application also provides a first indicator 30, so as to prompt the staff of the current start / stop status of the transport member 11, thereby further improving the safety performance of the overhead crane 1 during maintenance.
[0028] In some embodiments of the present application, the first indicator 30 may include an indicator light. When the transport member 11 is in a started state, that is, the first switch 20 is not closed and the transport member 11 is not powered off, the indicator light may light up green. When the transport member 11 is in a closed state, that is, the first switch 20 is closed and the transport member 11 is powered off, the indicator light may light up red to provide visual prompt information to the staff.
[0029] Alternatively, the first indicator 30 may include a buzzer. When the transport member 11 is in the start-up state, that is, the first switch 20 is not closed and the transport member 11 is not powered off, the buzzer does not sound. When the transport member 11 is in the shut-down state, that is, the first switch 20 is closed and the transport member 11 is powered off, the buzzer emits a prompt sound to provide auditory prompt information to the staff.
[0030] Alternatively, the first indicator 30 may include an indicator light and a buzzer. When the transport member 11 is in the start-up state, that is, the first switch 20 is not closed and the transport member 11 is not powered off, the indicator light is green and the buzzer is silent. When the transport member 11 is in the shut-down state, that is, the first switch 20 is closed and the transport member 11 is powered off, the indicator light is red and the buzzer sounds a prompt, so as to provide prompt information to the staff by combining vision and hearing.
[0031] In some embodiments of the present application, the first switch 20 includes a pull-rope switch, which is a purely mechanical travel protection switch that is not affected by external signals or electromagnetic interference. When an emergency occurs, the pull-rope switch can be pulled anywhere along the running track of the transport member 11 to send a stop signal to the transport member 11, thereby protecting people and equipment. Because the pull-rope switch has the characteristics of a travel switch and a micro switch, and also has sensing performance, and the pull-rope switch has the characteristics of reliable switch action, stable performance, fast frequency response, long service life, and strong anti-interference ability.
[0032] For further information, please see Figure 1 In some embodiments of the present application, the pull-rope switch is arranged on the side of the main body 10. Specifically, when the transport member 11 carries or lifts heavy objects, the force on the transport member 11 extends vertically. The pull-rope switch is located on the side of the main body 10, which can reduce the interference between the pull-rope switch and the transport member 11, thereby preventing the transport member 11 from getting entangled with the pull-rope switch during operation.
[0033] After the pull-rope switch is pulled, the display state of the first indicator 30 changes. The pull-rope switch is arranged adjacent to the first indicator 30, so that the first indicator 30 next to the pull-rope switch can be observed immediately, which is convenient for the staff to timely check the indication information of the first indicator 30. When the transport member 11 fails, the staff can judge whether the transport member 11 is closed according to the information of the first indicator 30, and the staff can also judge whether there is anyone on the running track of the overhead travelling vehicle 1 according to the indication information of the first indicator 30, so that the staff will not blindly go to the running track of the overhead travelling vehicle 1, thereby reducing the occurrence of accidents and ensuring the safety of maintenance personnel.
[0034] See also Figure 2 In some embodiments of the present application, the main body 10 also includes a guide rail assembly 12, the guide rail assembly 12 extends along the first direction L1, the transport member 11 is slidingly connected to the guide rail assembly 12 along the first direction L1, and the first indicator 30 is arranged on the side of the guide rail assembly 12.
[0035] It is easy to understand that the transport member 11 can move along the first direction L1 on the guide rail assembly 12 to transport items. When a certain overhead crane 1 is performing troubleshooting, the staff can disconnect the power supply of the transport member 11 through the corresponding first switch 20. At this time, the first indicator member 30 sends an indication signal. The first indicator member 30 is located on the side of the guide rail assembly 12 to facilitate the staff's viewing and reduce the obstruction of the first indicator member 30 by the transport member.
[0036] Please continue to see Figure 2 In some embodiments of the present application, the guide rail assembly 12 includes two mutually parallel first guide rails 121, and the main body 10 also includes a connecting beam 13, which is arranged between the two first guide rails 121, and the connecting beam 13 extends along the second direction L2, and the second direction L2 is perpendicular to the first direction L1. The arrangement of the connecting beam 13 can improve the strength of the main body 10, thereby enhancing the strength of the overhead crane 1 and improving the transportation efficiency of the overhead crane 1. Among them, the first indicator 30 is arranged on a side of one first guide rail 121 away from the other first guide rail 121, that is, the first indicator 30 is arranged on the side of one of the first guide rails 121, so as to facilitate the staff to check and reduce the shielding of the first indicator 30 by the conveying member.
[0037] For further information, please see Figure 2 In some embodiments of the present application, a plurality of first indicator members 30 are provided, and the plurality of first indicator members 30 are spaced apart on the first guide rail 121, so that the number of the first indicator members 30 is increased, so that the staff can more easily see the indication information of the first indicator members 30, thereby ensuring the safety of the maintenance personnel.
[0038] Alternatively, in some embodiments of the present application, a plurality of first indicator members 30 are provided, and a plurality of first indicator members 30 are provided on opposite sides of the guide rail assembly 12, thereby enabling the first indicator members 30 to more clearly display the working status of the conveying member, which is convenient for the staff to check.
[0039] In some embodiments of the present application, the overhead travelling crane 1 further includes a second indicator (not shown in the figure), which is connected to the first switch 20 and is used to indicate the opening and closing of the first switch 20. Taking the second indicator as a light bulb as an example, if the first switch 20 is turned on or off, the second indicator will display different light colors; if there is a problem with the first switch 20, the second indicator will not light up, and the setting of the second indicator can reduce the troubleshooting time of the first switch 20.
