Abstract
Description
Technical Field
[0001] This application relates to the field of overhead crane technology, and in particular to overhead crane equipment. Background Technology
[0002] A gantry crane, also known as an overhead crane, is a piece of equipment used for moving and lifting heavy objects. It can be used for loading and unloading cargo and bulk materials in outdoor freight yards and material yards. Typically, a gantry crane consists of a large metal structure, including a boom, a rotating and lifting arm, and lifting machinery such as steel cables, chains, or electric ropes. It is usually operated using an electric or hydraulic system.
[0003] As a type of gantry crane, magnetic cranes rely on the electromagnetic field released by electromagnets to couple with the microscopic magnetic effect formed by the internal electron movement of metal objects such as iron blocks, thereby achieving the attraction between the electromagnets and the metal objects and realizing the handling and transfer of metal objects. This method is highly efficient, fast, and has good flexibility.
[0004] However, since metal objects such as iron blocks are often heavy, the electromagnet may not fully attract them. This can result in situations where the metal object is not attracted when the electromagnet is lifted, leading to airlift operations, which affects handling efficiency. In some cases, the metal object may be moved without being firmly attracted by the electromagnet, causing it to fall and resulting in a safety accident. Summary of the Invention
[0005] Therefore, it is necessary to provide a gantry crane to address the aforementioned technical problems, thereby improving the conveying efficiency and safety of the gantry crane.
[0006] A gantry crane device includes: a gantry crane body; an electromagnetic component fixedly connected to the gantry crane body, which, when energized, can attract a workpiece to be lifted, the workpiece to be lifted including a mating surface for connecting to the electromagnetic component, the electromagnetic component including an adsorption surface for attracting the workpiece to be lifted, and an installation groove on the electromagnetic component; and a detection component installed in the installation groove, which is used to detect the adsorption strength of the adsorption surface to the mating surface and / or the gap between the adsorption surface and the mating surface.
[0007] In one embodiment, the detection component includes a placement member and a detection unit. The placement member is installed in a mounting groove and has a placement slot. The detection unit can be installed in the placement slot and can detect the adsorption strength of the adsorption surface on the bonding surface and / or the gap between the adsorption surface and the bonding surface.
[0008] In one embodiment, the housing is movably mounted in the mounting slot, and the overhead crane also includes a transmission assembly connected to the housing, which is capable of driving the housing to move in the mounting slot under the action of an external force.
[0009] In one embodiment, the transmission assembly includes a transmission member and a rotating member, the rotating member being rotatably connected to the transmission member, and the receiving member being provided with a first limiting groove. The transmission member is configured to be installed in the first limiting groove, and the rotating member is configured to rotate under the action of an external force, thereby causing the transmission member to move in the first limiting groove and causing the receiving member to move in the mounting groove.
[0010] In one embodiment, the transmission assembly further includes a locking unit connected to the rotating member for preventing the rotating member from rotating.
[0011] In one embodiment, the locking unit includes a fixing member and a locking member. The fixing member is fixedly connected to the electromagnetic member, and the locking member is connected to the fixing member, with a locking cavity formed between the locking member and the fixing member. The rotating member can be fixed in the locking cavity.
[0012] In one embodiment, the overhead crane further includes a reset member, one end of which is connected to the receiving member and the other end of which is connected to the mounting slot. The reset member is used to restore the position of the receiving member in the mounting slot.
[0013] In one embodiment, the detection component includes a limiting member connected to the receiving member, and the electromagnetic member is provided with a second limiting groove, the limiting member being configured to move in the second limiting groove.
[0014] In one embodiment, the receiving element has a first opening facing the mating surface, and the adsorption surface has a second opening facing the receiving element. The first opening is connected to the second opening, so that the detection unit can detect the adsorption strength of the adsorption surface on the mating surface and / or the gap between the adsorption surface and the mating surface without obstruction.
[0015] In one embodiment, the overhead crane further includes a cleaning component connected to the electromagnetic element and disposed within a second opening, the cleaning component being used to clean the detection unit.
[0016] The aforementioned gantry crane equipment, by installing a detection component inside the electromagnetic component, can detect the adsorption strength of the adsorption surface and / or the gap between the adsorption surface and the adsorption surface in real time. Based on the adsorption strength and the gap, it can determine whether to transport the equipment. This helps to avoid air transport, improve the handling efficiency of the gantry crane equipment, reduce the possibility of the lifting item falling during the handling process, and improve the safety of the gantry crane equipment.

[0033] See Figure 1 and Figure 2 , Figure 1 and Figure 2 A schematic diagram of a gantry crane device according to an embodiment of this application is shown. The gantry crane device 100 provided in one embodiment of this application includes a gantry crane body 10, an electromagnetic component 20, and a detection assembly 30.
[0034] The gantry crane body 10 is the supporting structure of the gantry crane equipment 100, used to realize the load-bearing and movement of the gantry crane equipment 100. Optionally, the gantry crane body 10 may include a gantry crane longitudinal beam, which carries the workpiece to be lifted and moves it in different directions to move the workpiece to a preset position.
[0035] The electromagnetic component 20, such as an electromagnet, generates electromagnetic force using the principle of electromagnetic induction. After the current is turned on, the electromagnetic component 20 can firmly attract the object to be lifted, thereby realizing the transportation of the object. The electromagnetic component 20 is fixedly connected to the gantry crane body 10, and the electromagnetic component 20 can move with the gantry crane body 10 to lift the object to be lifted to the preset position.
[0036] Feasibly, the gantry crane body 10 includes a plurality of electromagnetic components 20, which are spaced apart at the bottom of the gantry crane body 10. This improves the overall attraction force of the electromagnetic components 20 and makes the gantry crane 100 suitable for lifting objects of different sizes, thus improving the applicability of the gantry crane 100. Preferably, the plurality of electromagnetic components 20 are equidistantly distributed at the bottom of the gantry crane body 10.
[0037] The electromagnetic component 20 is provided with a mounting groove 21, and the detection component 30 is installed in the mounting groove 21. The electromagnetic component includes an adsorption surface 24 for adsorbing the part to be lifted, and the part to be lifted includes a mating surface for connecting the electromagnetic component. The detection component 30 is used to detect the adsorption strength of the adsorption surface 24 to the mating surface and / or the gap between the adsorption surface 24 and the mating surface. The mounting groove 21 provides a receiving space for the detection component 30, which facilitates the installation of the detection component 30 and the detection of the connection between the electromagnetic component 20 and the part to be lifted. It reduces the possibility that the detection component 30 will detach from the electromagnetic component 20 when the electromagnetic component 20 moves, and improves the overall reliability of the overhead crane 100.
[0038] By installing a detection component 303 inside the electromagnetic component 20, the detection component 303 can detect the adsorption strength of the adsorption surface 24 to the mating surface and / or the gap between the adsorption surface 24 and the mating surface in real time. Based on the adsorption strength and the gap, it can be determined whether to transport the equipment. This helps to avoid air transport, improve the transport efficiency of the overhead crane 100, reduce the possibility of the lifting parts falling during transport, and improve the safety of the overhead crane 100.
[0039] In some embodiments, see Figure 2 and Figure 3 The detection component 30 includes a housing 31 and a detection unit 32. The housing 31 is installed in the mounting groove 21 and has a housing groove 311. The detection unit 32 can be installed in the housing groove 311 and can detect the connection between the electromagnetic component 20 and the lifting component to be lifted.
[0040] The mounting slot 311 provides installation space for the detection unit 32. Preferably, the mounting component 31 is movably installed in the mounting slot. The movement of the mounting component 31 relative to the mounting slot 21 facilitates the installation, replacement, and storage of the detection unit 32. It should be noted that the overhead crane 100 can select different detection units 32 according to requirements, thereby achieving different tests for the electromagnetic component 20 and the component to be hoisted. In other embodiments, the detection unit 32 can be directly installed in the mounting slot 21 without the need for the mounting component 31.
[0041] In the embodiments disclosed in this application, combined with Figure 5 The detection unit 32 includes a first sensor 321 and a second sensor 322. The first sensor 321 is a magnetic induction recognition sensor, which is a device that can convert various magnetic fields and their changes into electrical signals. When the electromagnetic component 20 begins to attract the object to be lifted, the first sensor 321 detects the change in the magnetic field generated by the electromagnetic component 20. This change in the magnetic field causes the magnetic probe inside the first sensor 321 to generate an electrical signal, thereby achieving a preliminary test of the attraction strength between the attraction surface 24 of the electromagnetic component 20 and the contact surface of the object to be lifted. Then, when the electromagnetic component 20 and the object to be lifted come into contact, the change in the electrical signal transmitted by the first sensor 321 further determines the attraction strength between the attraction surface 24 of the electromagnetic component 20 and the contact surface of the object to be lifted, judging whether the electromagnetic component 20 is tightly attracted to the object to be lifted, and thus judging whether there is a risk of the object to be lifted falling during the transfer process with the electromagnetic component 20.
[0042] The second sensor 322 is an infrared sensor, which uses the physical properties of infrared light for measurement. Through the second sensor 322, the gap between the adsorption surface 24 of the electromagnetic component 20 and the mating surface of the lifting component can be measured, identifying any abnormalities in the connection between the electromagnetic component 20 and the lifting component. Furthermore, using the detection results of the second sensor 322, it can be determined whether there are gaps at the connection between the electromagnetic component 20 and the lifting component, i.e., whether the connection between the electromagnetic component 20 and the lifting component is tight.
[0043] By comprehensively analyzing the detection results of the first sensor 321 and the second sensor 322, it is determined whether the gantry crane component should be moved, thereby improving the handling efficiency and safety of the gantry crane equipment 100. It should be noted that the specific types of the first sensor 321 and the second sensor 322 can be selected according to the corresponding detection requirements.
[0044] Feasibly, the second sensor 322 is connected to the first sensor 321, allowing the second sensor 322 and the first sensor 321 to be installed as a single unit, simplifying the installation process of the detection unit 32 and improving the installation efficiency of the detection unit 32. See, for example... Figure 5 and Figure 6The first sensor 321 is provided with a first hook 3211, and the second sensor 322 is provided with a second hook 3221. The first hook 3211 is connected to the second hook 3221, thereby realizing the connection between the second sensor 322 and the first sensor 321.
[0045] In some embodiments, see Figure 3 The overhead crane 100 also includes a transmission assembly 40, which is connected to the housing 31. The transmission assembly 40 can drive the housing 31 to move in the mounting slot 21 along the first direction S1 under the action of external force. The transmission assembly 40 facilitates the movement of the housing 31, thereby making it easier to install, remove, or replace the detection unit 32.
[0046] Further, see Figure 3 The transmission assembly 40 includes a transmission member 41 and a rotating member 42. The rotating member 42 is rotatably connected to the transmission member 41. The housing member 31 is also provided with a first limiting groove 312 extending along a second direction S2. The transmission member 41 is configured to be installed in the first limiting groove 312. The rotating member 42 is configured to rotate under the action of an external force, causing the transmission member 41 to move along the second direction S2 in the first limiting groove 312 and causing the housing member 31 to move along the first direction S1 in the mounting groove 21. The first direction S1 and the second direction S2 intersect each other. By converting the rotation of the rotating member 42 into linear motion of the transmission member 41 and the housing member 31, the housing member 31 is moved out of the mounting groove 21 to complete the installation or removal of the detection unit 32.
[0047] Specifically, in this embodiment, the rotating member 42 includes a connecting portion 421, a connecting portion 422, and a force-applying portion 423. The connecting portion 421 is rotatably connected to the transmission member 41 to transmit power. The connecting portion 422 passes through the electromagnetic member 20, with one end fixedly connected to the connecting portion 421 and the other end fixedly connected to the force-applying portion 423. By applying force to the force-applying portion 423, the rotation of the connecting portion 421 is facilitated, thereby enabling the movement of the housing member 31. It is understood that the connecting portion 421, the connecting portion 422, and the force-applying portion 423 can be provided individually or as a single unit.
[0048] In some embodiments, see Figure 3 and Figure 4 The transmission assembly 40 also includes a locking unit 43, which is connected to the rotating member 42 and is used to prevent the rotating member 42 from rotating. By locking the rotating member 42 with the locking unit 43, the housing member 31 can be stably installed in the mounting groove 21 when the electromagnetic member 20 moves, thereby ensuring that the detection unit 32 is stably installed in the housing groove 311. This prevents the rotation of the rotating member 42 from affecting the detection results of the detection unit 32 and ensures the safety of the overhead crane 100 during use.
[0049] Furthermore, the locking unit 43 includes a fixing member 431 and a locking member 432. The fixing member 431 is fixedly connected to the electromagnetic member 20, and the locking member 432 is connected to the fixing member 431, with a locking cavity 433 formed between the locking member 432 and the fixing member 431. The rotating member 42 can be fixed in the locking cavity 433. In other embodiments, the locking unit 43 can also be locked by the rotating member 42, such as a locking groove or a buckle.
[0050] It should be noted that in the embodiments disclosed in this application, the locking member 432 needs to both lock the rotating member 42 and enable the rotating member 42 to be unlocked in order to complete the rotation of the rotating member 42, thereby realizing the control of the movement process of the placement member 31.
[0051] Feasibly, the fixing member 431 is provided with a locking groove 4311, and the locking member 432 includes a stop part 4321 and an elastic part 4322. One end of the elastic part 4322 is fixedly connected to the locking groove 4311, and the other end is fixedly connected to the stop part 4321. When the rotating member 42 is driven to rotate by an external force, the rotating member 42 will squeeze the stop part 4321, causing the elastic part 4322 to contract, so that the rotating member 42 can leave the locking cavity 433 and rotate further, so that the placement member 31 can move in the mounting groove 21.
[0052] Specifically, in this embodiment, see [reference] Figure 4 The two inner sides of the fixing member 431 are provided with two engaging grooves 4311, the two locking members 432 are provided with two opposite parts, the two stop parts 4321 are provided with opposite parts, and the two elastic parts 4322 are respectively fixedly connected to the two engaging grooves 4311. Thus, under the action of external force, the rotating member 42 can more easily move the two stop parts 4321 to complete the unlocking process.
[0053] Preferably, the end face of the stop portion 4321 away from the engagement groove 4311 is configured as an arc surface. The arc surface makes the edges of the stop portion 4321 smooth, making it easier for the stop portion 4321 to move when the rotating member 42 presses against it, and reducing the possibility of damage to the rotating member 42, thus enabling the long-term use of the transmission assembly 40.
[0054] In some embodiments, see Figure 3 The overhead crane 100 also includes a reset member 50, one end of which is connected to the receiving member 31 and the other end is connected to the mounting groove 21. The reset member 50 is used to restore the position of the receiving member 31 in the mounting groove 21.
[0055] Optionally, the reset member 50 is a spring. With the reset member 50, when an external force is applied to move the housing 31, the housing 31 will stretch the reset member 50. The reset member 50, in order to restore its deformation, will generate a tensile force acting on the housing 31. After the external force is removed, the reset member 50 will cause the housing 31 to return to its initial position. Furthermore, the reset member 50 makes it difficult for the housing 31 to leave the mounting slot 21, ensuring the installation stability of the housing 31 and enabling the overhead crane 100 to operate normally and stably for a long period.
[0056] Specifically, see Figure 3 and Figure 5 The housing 31 has a connecting part 422 and a receiving groove 314. One end of the reset member 50 is fixedly connected to the connecting part 422 and the reset member 50 is installed in the receiving groove 314. To facilitate the connection between the electromagnetic component 20 and the reset member 50 and to avoid the reset member 50 being affected by the electromagnetic component 20, a connecting part 60 is also provided between the reset member 50 and the electromagnetic component 20. That is, the other end of the reset member 50 is fixedly connected to the connecting part 60. The connecting part 60 is disposed in the mounting groove 21 and fixedly connected to the electromagnetic component 20. This arrangement makes full use of the space of the housing 31, has a simple and reliable structure, and improves the overall compactness of the overhead crane 100.
[0057] Further, see Figure 2 and Figure 3 The detection component 30 includes a limiting member 33, which is connected to the housing member 31. A second limiting groove 22 is provided on the side wall of the mounting groove 21 of the electromagnetic component 20. The limiting member 33 is configured to move in the second limiting groove 22 along the first direction S1.
[0058] The setting of the limiting member 33 and the second limiting groove 22 restricts the movement direction of the placement member 31, which facilitates the drive of the placement member 31 by the transmission unit, avoids the irregular movement of the placement member 31 from affecting the installation of the detection unit 32, and improves the assembly efficiency of the detection component 30.
[0059] Feasibly, the limiting member 33 is slidably connected to the second limiting groove 22 to ensure the smooth operation of the transmission process. Furthermore, the setting of the second limiting groove 22 restricts the movement stroke of the limiting member 33, effectively preventing the placement member 31 from dislodging from the mounting groove 21.
[0060] In some embodiments, see Figure 5 and Figure 7The housing 31 has a first opening 315 facing the mating surface and is positioned between the detection unit 32 and the electromagnetic component 20. The electromagnetic component 20 has a second opening 23 facing the housing and is positioned between the lifting component to be lifted and the housing 31. The first opening 315 can communicate with the second opening 23, meaning that the housing 31 and the electromagnetic component 20 are open on the side closer to the lifting component to be lifted. This arrangement allows the detection unit 32 to detect the adsorption strength of the adsorption surface 24 to the mating surface and / or the gap between the adsorption surface 24 and the mating surface without obstruction. In other words, the signal from the detection unit 32 can directly reach the lifting component to be lifted, reducing the obstruction of the signal from the housing 31 and the electromagnetic component 20, thus obtaining more accurate detection results.
[0061] Feasibly, since the second sensor 322 is usually small in size, a magnetic suction member 3221 is provided on the end face of the second sensor 322 away from the first opening 315. The magnetic suction member 3221 is connected to the housing member 31 to further fix the second sensor 322, so as to prevent the second sensor 322 from falling off due to the large size of the first opening 315, and to ensure the normal use of the second sensor 322.
[0062] In some embodiments, see Figures 7 to 9 The overhead crane 100 also includes a cleaning component 70, which is connected to the electromagnetic component 20 and disposed within the second opening 23. The cleaning component 70 is used to clean the detection unit 32. Due to the arrangement of the first opening 315 and the second opening 23, after a period of use, dust or metal shavings may accumulate on the detection unit 32, affecting its detection accuracy. The cleaning component 70 can clean the dust or metal shavings on the detection unit 32, reducing the impact of contaminants on the detection results.
[0063] Specifically, in this embodiment, the cleaning component 70 includes a first driving member 71 and a cleaning member 72. The first driving member 71 is connected to the electromagnetic member 20 and can drive the cleaning member 72 to rotate. The cleaning member 72 is connected to the detection unit 32 and is used to clean the detection unit 32. Optionally, the first driving member 71 is a motor, and the cleaning member 72 is a cleaning roller with soft bristles on its surface.
[0064] To facilitate cleaning of various positions of the detection unit 32, the cleaning assembly also includes an adjustment unit 73, which includes a second drive member 731 and an adjustment member. The adjustment member is connected to the cleaning member 72 and the electromagnetic member 20. The second drive member 731 is connected to the adjustment member and can drive the adjustment member to rotate, thereby adjusting the position of the cleaning member 72.
[0065] Feasibly, the adjusting component includes a screw sleeve 733 and a screw 732. One end of the screw 732 is connected to the second driving component 731, and the other end is connected to the electromagnetic component 20 through a bearing. The screw sleeve 733 is threadedly connected to the screw 732 and connected to the cleaning component 72. Under the drive of the second driving component 731, the screw 732 will rotate, causing the position of the screw sleeve 733 to change, thereby changing the position of the cleaning component 72, so as to achieve cleaning of different positions of the detection unit 32.
[0066] In the embodiments disclosed in this application, the cleaning component 72 extends along a first direction S1, with one end connected to a second driving component 731 and the other end connected to a screw sleeve 733. The screw 732 extends along a third direction S3, with one end connected to the second driving component 731 and the other end rotatably connected to the electromagnetic component 20. The second driving component 731 is connected to the electromagnetic component 20 along the third direction S3, and the first driving component 71 is connected to the electromagnetic component 20 along the first direction S1. To achieve uniform movement at both ends of the cleaning component 72, the electromagnetic component 20 is provided with a sliding groove 231 along the third direction S3, and the first driving component 71 is slidably connected to the sliding groove 231. The first direction S1, the second direction S2, and the third direction S3 intersect each other; preferably, the first direction S1, the second direction S2, and the third direction S3 are perpendicular to each other.
[0067] Combination Figure 8 and Figure 10 To ensure that the first driving member 71 slides along the third direction S3, the first driving member 71 is also provided with a locking part 711, and a locking groove 231 is also provided in the sliding groove 231. The locking part 711 is engaged with the locking groove 231, so that the cleaning member 72 can move evenly along the third direction S3 under the drive of the second driving member 731, and complete the effective cleaning of the detection unit 32. In other embodiments, the cleaning member 72 extends along the third direction S3, and the screw 732 extends along the first direction S1.
[0068] When the overhead crane 100 disclosed in this application is in use, an external force is applied to the rotating member 42, first causing the surface of the rotating member 42 to contact the two stop portions 4321. Further application of external force causes the rotating member 42 to compress the two stop portions 4321 and the elastic portion 4322 into the engagement groove 4311, causing the two stop portions 4321 to move in opposite directions, releasing the lock on the rotating member 42. Further application of external force causes the rotating member 42 to perform an arc motion, driving the transmission member 41 to move in the second limiting groove 22 along the second direction S2, and driving the receiving member 31 to move in the mounting groove 21 along the first direction S1. The receiving member 31 is stretched and retracted along the first direction S1. When part of the housing 31 moves out of the mounting groove 21, the first hook 3211 and the second hook 3221 are hooked together, so that the first sensor 321 and the second sensor 322 are connected. Then, the first sensor 321 and the second sensor 322 are placed in the housing groove 311 and pushed into the housing groove 311. Then, the fixing of the rotating member 42 is released at a uniform speed. Under the action of the reset member 50, the reset member 50 retracts and drives the housing 31 to reset, so that the housing 31 and the detection unit 32 move to the preset installation position in the mounting groove 21.
[0069] After the detection component 30 moves to the preset installation position, due to the setting of the first opening 315 and the second opening 23, the first sensor 321 and the second sensor 322 are located above the mating surface of the lifting component to be lifted. Furthermore, when the electromagnetic component 20 begins to attract the lifting component to be lifted, the movement of the electromagnetic component 20 and the lifting component to be lifted will first generate a change in the magnetic field. This change in the magnetic field will cause the magnetic probe inside the first sensor 321 to generate an electrical signal, thereby realizing the detection of the attraction strength of the attraction surface 24 of the electromagnetic component 20 to the mating surface of the lifting component to be lifted. Then, when the electromagnetic component 20 and the lifting component to be lifted come into contact, the first sensor 321 determines whether the attraction surface 24 of the electromagnetic component 20 is tightly attracted to the mating surface of the lifting component to be lifted by the change in the magnetic field electrical signal, and thus determines whether there is a risk of the lifting component to be lifted falling during the transfer process by the electromagnetic component 20.
[0070] Next, the second sensor 322 measures the gap between the adsorption surface 24 of the electromagnetic component 20 and the mating surface of the lifting component to be lifted, finds the abnormal connection between the electromagnetic component 20 and the lifting component to be lifted, detects whether there is a gap at the connection between the electromagnetic component 20 and the lifting component to be lifted, and transmits the signal. By comprehensively analyzing the detection results of the first sensor 321 and the second sensor 322, it is determined whether the lifting component should be moved.
[0071] After the first sensor 321 and the second sensor 322 have been used for a period of time, in order to ensure the detection accuracy of the first sensor 321 and the second sensor 322, the first drive component 71 and the second drive component 731 are turned on. The output shaft of the first drive component 71 drives the cleaning component 72 to rotate. When the cleaning component 72 rotates, it sweeps away dust or metal shavings and other contaminants at the bottom of the first sensor 321 and the second sensor 322 through the soft brush on its surface. The second drive component 731 drives the screw 732 to rotate. The screw 732 drives the screw sleeve 733 to move through the transmission of the surface thread, thereby adjusting the cleaning position of the cleaning component 72 and achieving a more complete cleaning of the first sensor 321 and the second sensor 322.
[0072] The overhead crane 100 in this application has the advantages of accurate and reliable detection results and ease of use. By setting detection units 32, such as the first sensor 321 and the second sensor 322, inside the electromagnetic component 20, the detection units 32 detect the connection between the electromagnetic component 20 and the component to be lifted from different angles, such as the adsorption strength of the adsorption surface 24 to the mating surface and the gap between the adsorption surface 24 and the mating surface. This enables accurate detection and analysis of the connection between the electromagnetic component 20 and the component to be lifted, thereby obtaining corresponding judgment instructions based on the actual situation. This reduces the possibility of the component to be lifted not being adsorbed or not being adsorbed tightly, reduces the mechanical energy consumption of repeated operation of the overhead crane 100, improves the lifting efficiency, and at the same time reduces the possibility of safety accidents.
