Description

Technical Field

[0001] The invention relates to the technical field of hoisting, in particular to a civil aircraft maintenance hoisting device. Background Art

[0002] With the development of the times, aircraft have been widely used in many fields. Aircraft generally refers to machines that achieve aerodynamic flight through the relative movement of the fuselage and the air. However, aircraft are assembled from a large number of parts. Often after a period of use, they need to be inspected and maintained. To repair or replace some parts, corresponding lifting equipment is needed to lift the parts for easy maintenance.

[0003] When repairing civil aircraft, it is necessary to hoist long rectangular parts. However, it is difficult to determine the center of gravity of long rectangular parts during hoisting, causing the parts to tilt toward the center of gravity during hoisting. The horizontality of the parts cannot be guaranteed, which can easily cause safety hazards. Summary of the invention

[0004] The purpose of the present invention is to provide a civil aircraft maintenance hoisting device to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution for civil aircraft maintenance hoisting equipment, the hoisting equipment includes a main frame, a fixing mechanism, an active trolley, a beam trolley, an electric hoist and a hoisting mechanism, the main frame is slidably connected to the fixing mechanism, the active trolley is firmly connected to the main frame, the active trolley is slidably connected to the fixing mechanism, the beam trolley is slidably connected to the main frame, the electric hoist is firmly connected to the beam trolley, the output end of the electric hoist is transmission-connected to the hoisting mechanism, and the hoisting mechanism is used to maintain the stability of the hoisting process.

[0006] The main frame is fixed on the wall to provide stable support for hoisting. During hoisting, the electric hoist is first moved to a suitable position for hoisting through the active trolley and the crossbeam trolley. The electric hoist is the main power component of the hoisting equipment, and the hoisting mechanism adopts double hooks for hoisting. When repairing civil aircraft, long strips of parts need to be hoisted, but it is difficult to determine the center of gravity of the long strips of parts during hoisting, causing the parts to tilt to one side of the center of gravity during hoisting. The horizontality of the parts cannot be guaranteed, which can easily cause safety hazards.

[0007] Furthermore, the lifting device mechanism includes a main beam, a force-bearing component and an adjusting component. The electric hoist is provided with a controller and a connecting part, the controller is used to control the action of the electric hoist, the main beam is provided with a hinged seat, the connecting part is hinged to the hinged seat, support frames are arranged at both ends of the main beam, the force-bearing component is rotatably connected to the support frame, the force-bearing component is used to judge the magnitude of the pulling force, the adjusting component is tightly connected to the support frame, and the adjusting component is used to adjust the horizontality of the parts.

[0008] The electric hoist is hinged to the hinge seat on the main beam through a connecting piece, which facilitates the disassembly and assembly of the lifting mechanism. The controller can control the rise and fall of the electric hoist, thereby driving the lifting mechanism to move up and down to lift the parts to be lifted. The support frame is used to provide an installation basis for the force-bearing components and the adjustment components. During lifting, if the center of gravity of the part is offset from the center of the main beam, the part will tilt to one side, and the tension on the force-bearing component close to the center of gravity of the part is greater than the tension on the other side. The force-bearing component can drive the adjustment component at the corresponding position to move according to the difference in tension, thereby adjusting the tilted parts to a horizontal state, thereby improving safety during lifting.

[0009] Furthermore, the force-bearing component includes a sleeve, an adjusting shaft, an arc-shaped slider, a tension spring, a pressure-regulating piston and a clamping block. The adjusting shaft is rotatably connected to the support frame, the sleeve is rotatably connected to the adjusting shaft, an arc-shaped slide groove, a liquid storage chamber and a through flow channel are provided in the adjusting shaft, the arc-shaped slider is slidably connected to the arc-shaped slider, one end of the tension spring is firmly connected to the arc-shaped slider, the other end of the tension spring is firmly connected to the inner wall of the arc-shaped slide groove, the pressure-regulating piston is firmly connected to the arc-shaped slider, the pressure-regulating piston is slidably connected to the liquid storage chamber, the liquid storage chamber is communicated with the through flow channel, hydraulic oil is filled in the liquid storage chamber, the through flow channel is communicated with the adjusting component, a steel wire rope is wound around the sleeve, a clamping groove is provided on the sleeve, the clamping block is firmly connected to the arc-shaped slider, and the clamping block is clamped in the clamping groove.

[0010] The force-bearing components at both ends of the main beam are connected to the lifting parts through the wire rope wound on the sleeve. When the part deflects to one side during lifting, it indicates that the force-bearing component on the deflected side is close to the center of gravity of the part, that is, the wire rope on this side is subjected to greater tension than that on the other side. In the initial state, the adjusting shaft does not rotate, and the sleeve located on the outside of the adjusting shaft will deflect to the same side under the action of the wire rope tension, thereby driving the arc-shaped slider connected to the clamping block to slide along the arc-shaped slide groove to one side, the tension spring is stretched under force, and the pressure-regulating piston slides along the liquid storage chamber driven by the arc-shaped slider, thereby pressing the hydraulic oil in the liquid storage chamber into the through flow channel, thereby driving the adjusting component to move. The greater the angle of deflection of the part to one side, the greater the angle of deflection of the sleeve on this side on the adjusting shaft, and the more hydraulic oil is pressed into the through flow channel.

[0011] Furthermore, the liquid storage chamber is arc-shaped, and the shape of the pressure regulating piston matches the shape of the liquid storage chamber.

[0012] The arc-shaped liquid storage chamber matches the arc-shaped slide groove, thereby ensuring that the pressure regulating piston can move smoothly in the liquid storage chamber driven by the arc-shaped slide block.

[0013] Furthermore, the adjustment component includes a protective shell, a first piston, a second piston, an iron core, a repelling magnet and a liquid distribution disk. The liquid distribution disk is tightly connected to the support frame, the liquid distribution disk is rotatably connected to the rotating shaft of the adjustment shaft, the inner cavity of the liquid distribution disk is connected to the through flow channel, the protective shell is tightly connected to the support frame, a guide groove is provided in the protective shell, the guide groove is connected to the liquid distribution disk pipeline, the first piston is slidably connected to the guide groove, the iron core is tightly connected to the first piston, a coil is wound around the protective shell, the iron core is inserted into the coil to form an electromagnet, the facing surfaces of the electromagnet and the repelling magnet are the same magnetic poles, the repelling magnet is tightly connected to the second piston, and the second piston is slidably connected to the guide groove.

[0014] Because the greater the angle of deflection of the part to one side, the greater the angle of deflection of the sleeve on this side on the adjusting shaft, the more hydraulic oil is pressed into the through flow channel, and the more hydraulic oil flows into the guide groove through the distribution plate. The longer the distance the first piston moves along the guide groove to the other side, the longer the distance the iron core is inserted into the coil, and the greater the magnetic force of the electromagnet composed of the coil and the iron core. According to the principle of like repels like, the greater the repulsive force on the repelling magnet, the longer the distance the second piston moves along the guide groove.

[0015] Furthermore, hydraulic oil is filled on one side of the guide groove close to the second piston. The sling mechanism also includes a transmission assembly. The guide groove is connected to the transmission assembly, and the transmission assembly is used to drive the adjustment shaft to rotate.

[0016] The greater the angle at which the part deflects to one side, the longer the distance the second piston moves along the guide groove, the more hydraulic oil is pressed into the transmission assembly, and the greater the angle at which the adjusting shaft rotates. The direction in which the adjusting shaft rotates is opposite to the direction in which the wire rope is pulled, which drives the shaft sleeve on the side close to the center of gravity of the part to reel in the wire rope, thereby shortening the length of the wire rope on the deflected side of the part and adjusting the deflected part to a horizontal state.

[0017] Furthermore, the transmission assembly includes a fixed seat, a rack and a return spring, a transmission cavity is provided in the fixed seat, the rack is slidably connected to the transmission cavity, one end of the return spring is fastened to the rack, and the other end of the return spring is fastened to the inner wall of the transmission cavity, and a gear is provided at one end of the adjustment shaft close to the transmission assembly, the gear is meshed with the rack, and the gear is located in the transmission cavity; In the initial state: the rack is located at the bottom end of the transmission cavity; During adjustment: the rack moves upward along the transmission cavity.

[0018] When the force-bearing component is subjected to the pulling force of the part on the wire rope, in the initial state, because the rack is at the bottom end of the transmission cavity, and the gear on the adjusting shaft is meshed with the rack, the rack limits the gear, and the gear cannot rotate clockwise, so the adjusting shaft cannot be driven to rotate clockwise; when the adjusting component is in motion, under the force transmission of the hydraulic oil, the rack will be pushed to move up along the transmission cavity, the reset spring will be compressed, and the gear will rotate counterclockwise, thereby driving the adjusting shaft to rotate, thereby driving the sleeve on the side close to the center of gravity of the part to reel in the wire rope, thereby shortening the length of the wire rope on the deflected side of the part. The tension on the force-bearing component on the side away from the center of gravity of the part is smaller and cannot overcome the elastic force of the tension spring. The length of the wire rope on this side remains unchanged, so that the deflected part is adjusted to a horizontal state; and because the greater the angle of deflection of the part to one side, the longer the distance the second piston moves along the guide groove, the more hydraulic oil is pressed into the transmission component, the longer the distance the rack moves up along the transmission cavity, and the longer the length of the wire rope that the sleeve on the side close to the center of gravity of the part can be wound. That is, the winding length of the wire rope is automatically adjusted according to the deflection angle of the part, thereby maintaining the horizontal state of the part during the lifting process.

[0019] Furthermore, a connecting beam is provided on the main frame, and a beam trolley is slidably connected to the connecting beam. The beam trolley is used to drive the electric hoist to move left and right. The fixing mechanism includes an upper fixed beam and a lower fixed beam. The main frame is slidably connected to the upper fixed beam and the lower fixed beam. The active trolley is slidably connected to the lower fixed beam, and the active trolley is used to drive the main frame to move forward and backward along the upper fixed beam and the lower fixed beam.

[0020] The connecting beam is used to provide a moving track for the beam trolley. The upper fixed beam and the lower fixed beam of the fixing mechanism are used to be fixed on the corresponding wall to provide a stable working environment for the entire device. The active trolley cooperates with the beam trolley to drive the electric hoist to move forward, backward, left and right, thereby meeting the lifting needs of different positions.

[0021] Compared with the prior art, the present invention has the following beneficial effects: When the adjusting component is in action, under the force transmission of the hydraulic oil, the rack is pushed to move up along the transmission cavity, the reset spring is compressed, the gear rotates counterclockwise, and then drives the adjusting shaft to rotate, thereby driving the sleeve on the side close to the center of gravity of the part to reel in the wire rope, thereby shortening the length of the wire rope on the deflected side of the part, while the tension of the force-bearing component on the side away from the center of gravity of the part is smaller and cannot overcome the elastic force of the tension spring. The length of the wire rope on this side remains unchanged, so that the deflected part is adjusted to a horizontal state; and because the greater the angle of deflection of the part to one side, the longer the distance the second piston moves along the guide groove, the more hydraulic oil is pressed into the transmission component, the longer the distance the rack moves up along the transmission cavity, and the longer the length of the wire rope reeled by the sleeve on the side close to the center of gravity of the part, that is, the reeling length of the wire rope is automatically adjusted according to the deflection angle of the part, and the horizontal state of the part during the lifting process is maintained.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example: Figure 1-Figure 9 As shown, the present invention provides a technical solution for civil aircraft maintenance hoisting equipment, the hoisting equipment includes a main frame 1, a fixing mechanism 2, an active trolley 3, a beam trolley 4, an electric hoist 5 and a hoisting device mechanism 6, the main frame 1 is slidably connected to the fixing mechanism 2, the active trolley 3 is firmly connected to the main frame 1, the active trolley 3 is slidably connected to the fixing mechanism 2, the beam trolley 4 is slidably connected to the main frame 1, the electric hoist 5 is firmly connected to the beam trolley 4, the output end of the electric hoist 5 is transmission-connected to the hoisting device mechanism 6, and the hoisting device mechanism 6 is used to maintain the stability of the hoisting process.

[0026] The main frame 1 is fixed on the wall to provide stable support for hoisting. During hoisting, the electric hoist 5 is first moved to a suitable position for hoisting through the active trolley 3 and the beam trolley 4. The electric hoist 5 is the main power component of the hoisting equipment, and the hoisting mechanism 6 adopts double hooks for hoisting. When repairing civil aircraft, long strips of parts need to be hoisted, but it is difficult to determine the center of gravity of the long strips of parts during hoisting, causing the parts to tilt to one side of the center of gravity during hoisting. The horizontality of the parts cannot be guaranteed, which can easily cause safety hazards.

[0027] The hoist mechanism 6 includes a main beam 61, a force-bearing component 62 and an adjusting component 63. The electric hoist 5 is provided with a controller 51 and a connecting member 52. The controller 51 is used to control the action of the electric hoist 5. The main beam 61 is provided with a hinge seat 611. The connecting member 52 is hinged to the hinge seat 611. Support frames 612 are arranged at both ends of the main beam 61. The force-bearing component 62 is rotatably connected to the support frame 612. The force-bearing component 62 is used to determine the size of the pulling force. The adjusting component 63 is tightly connected to the support frame 612. The adjusting component 63 is used to adjust the horizontality of the parts.

[0028] The electric hoist 5 is hinged to the hinge seat 611 on the main beam 61 through the connecting piece 52, so as to facilitate the disassembly and assembly of the lifting device mechanism 6. The controller 51 can control the lifting and lowering of the electric hoist 5, thereby driving the lifting device mechanism 6 to move up and down, and lifting the parts to be lifted. The support frame 612 is used to provide an installation basis for the force-bearing component 62 and the adjustment component 63. During lifting, if the center of gravity of the part is offset from the center of the main beam, the part will tilt to one side, and the tension on the force-bearing component 62 close to the center of gravity of the part is greater than the tension on the other side. The force-bearing component 62 can drive the adjustment component 63 at the corresponding position to move according to the difference in tension, thereby adjusting the tilted part to a horizontal state, thereby improving safety during lifting.

[0029] The force-bearing component 62 includes a sleeve 621, an adjusting shaft 622, an arc-shaped slider 623, a tension spring 624, a pressure-regulating piston 625 and a clamping block 626. The adjusting shaft 622 is rotatably connected to the support frame 612, the sleeve 621 is rotatably connected to the adjusting shaft 622, an arc-shaped slide groove 6221, a liquid storage cavity 6222 and a through flow channel 6223 are provided in the adjusting shaft 622, the arc-shaped slider 623 is slidably connected to the arc-shaped slide groove 6221, one end of the tension spring 624 is fastened to the arc-shaped slider 623, and the other end of the tension spring 624 is fastened to the arc-shaped slider 623. One end is tightly connected to the inner wall of the arc-shaped slide groove 6221, the pressure-regulating piston 625 is tightly connected to the arc-shaped slider 623, the pressure-regulating piston 625 is slidingly connected to the liquid storage chamber 6222, the liquid storage chamber 6222 is connected to the through flow channel 6223, hydraulic oil is filled in the liquid storage chamber 6222, the through flow channel 6223 is connected to the adjusting component 63, a steel wire rope 627 is wound around the shaft sleeve 621, a clamping groove 6211 is provided on the shaft sleeve 621, a clamping block 626 is tightly connected to the arc-shaped slider 623, and the clamping block 626 is clamped in the clamping groove 6211.

[0030] The force-bearing components 62 at both ends of the main beam 61 are connected to the hoisting parts through the wire rope 627 wound on the sleeve 621. When the part deflects to one side during lifting, it indicates that the force-bearing component 62 on the deflected side is close to the center of gravity of the part, that is, the tension on the wire rope 627 on this side is greater than that on the other side. In the initial state, the adjustment shaft 622 does not rotate, and the sleeve 621 located outside the adjustment shaft 622 will deflect to the same side under the tension of the wire rope 627, thereby driving the arc connected to the block 626. The slider 623 slides to one side along the arc-shaped slide groove 6221, the tension spring 624 is stretched by force, and the pressure-regulating piston 625 slides along the liquid storage chamber 6222 driven by the arc-shaped slider 623, thereby pressing the hydraulic oil in the liquid storage chamber 6222 into the through flow channel 6223, thereby driving the adjustment component 63 to move, and the greater the angle of deflection of the part to one side, the greater the angle of deflection of the sleeve 621 on this side on the adjustment shaft 622, and the more hydraulic oil is pressed into the through flow channel 6223.

[0031] The liquid storage chamber 6222 is arc-shaped, and the shape of the pressure regulating piston 625 matches the shape of the liquid storage chamber 6222 .

[0032] The arc-shaped liquid storage chamber 6222 matches the arc-shaped slide groove 6221 , thereby ensuring that the pressure regulating piston 625 can move smoothly in the liquid storage chamber 6222 driven by the arc-shaped slide block 623 .

[0033] The regulating assembly 63 includes a protective shell 631, a first piston 632, a second piston 633, an iron core 634, a repelling magnet 635 and a liquid distribution plate 636. The liquid distribution plate 636 is tightly connected to the support frame 612, and the liquid distribution plate 636 is rotatably connected to the rotating shaft of the regulating shaft 622. The inner cavity of the liquid distribution plate 636 is connected to the through flow channel 6223. The protective shell 631 is tightly connected to the support frame 612. A guide groove 6311 is provided in the protective shell 631. The guide groove 6311 is provided in the protective shell 631. The groove 6311 is connected to the pipeline of the liquid distribution plate 636, the first piston 632 is slidably connected to the guide groove 6311, the iron core 634 is firmly connected to the first piston 632, a coil 637 is wound around the protective shell 631, the iron core 634 is inserted into the coil 637 to form an electromagnet, the facing surfaces of the electromagnet and the repelling magnet 635 are the same magnetic poles, the repelling magnet 635 is firmly connected to the second piston 633, and the second piston 633 is slidably connected to the guide groove 6311.

[0034] Because the greater the angle of deflection of the part to one side, the greater the angle of deflection of the sleeve 621 on this side on the adjusting shaft 622, the more hydraulic oil is pressed into the through flow channel 6223, and the more hydraulic oil flows into the guide groove 6311 through the distribution plate 636. The longer the distance the first piston 632 moves along the guide groove 6311 to the other side, the longer the distance the iron core 634 is inserted into the coil 637, and the greater the magnetic force of the electromagnet composed of the coil 637 and the iron core 634. According to the principle of like charges repel each other, the greater the repulsive force on the repelling magnet 635, and the longer the distance the second piston moves along the guide groove 6311.

[0035] Hydraulic oil is filled in the guide groove 6311 on one side close to the second piston 633 . The sling mechanism 6 further includes a transmission assembly 64 . The guide groove 6311 is connected to the transmission assembly 64 . The transmission assembly 64 is used to drive the adjustment shaft 622 to rotate.

[0036] The greater the angle of deflection of the part to one side, the longer the distance the second piston moves along the guide groove 6311, the more hydraulic oil is pressed into the transmission assembly 64, and the greater the angle of rotation of the adjusting shaft 622. The direction of rotation of the adjusting shaft 622 is opposite to the direction of the tension applied to the wire rope 627, which drives the shaft sleeve 621 on the side close to the center of gravity of the part to reel in the wire rope 627, thereby shortening the length of the wire rope 627 on the deflected side of the part, so that the deflected part is adjusted to a horizontal state.

[0037] The transmission assembly 64 includes a fixed seat 641, a rack 642 and a return spring 643. A transmission cavity 6411 is provided in the fixed seat 641. The rack 642 is slidably connected to the transmission cavity 6411. One end of the return spring 643 is fastened to the rack 642. The other end of the return spring 643 is fastened to the inner wall of the transmission cavity 6411. A gear 6224 is provided at one end of the adjustment shaft 622 close to the transmission assembly 64. The gear 6224 is meshed with the rack 642. The gear 6224 is located in the transmission cavity 6411. In the initial state: the rack 642 is located at the bottom end of the transmission cavity 6411; During adjustment: the rack 642 moves upward along the transmission cavity 6411.

[0038] When the force-bearing component 62 is subjected to the pulling force of the part on the wire rope 627, in the initial state, because the rack 642 is at the bottom end of the transmission chamber 6411, and the gear 6224 on the adjusting shaft 622 is meshed with the rack 642, the rack 642 limits the gear 6224, and the gear 6224 cannot rotate clockwise, so the adjusting shaft 622 cannot be driven to rotate clockwise; and when the adjusting component 63 is actuated, under the force transmission of the hydraulic oil, the rack 642 is pushed to move up along the transmission chamber 6411, the return spring 643 is compressed, and the gear 6224 rotates counterclockwise, thereby driving the adjusting shaft 622 to rotate, thereby driving the sleeve 621 on the side close to the center of gravity of the part to reel in the wire rope 627, thereby shortening the part. The length of the wire rope 627 on the deflected side of the part is reduced, while the tension on the force-bearing component 62 far from the center of gravity of the part is small and cannot overcome the elastic force of the tension spring 624. The length of the wire rope 627 on this side remains unchanged, so that the deflected part is adjusted to a horizontal state; and because the greater the angle of deflection of the part to one side, the longer the distance the second piston moves along the guide groove 6311, the more hydraulic oil is pressed into the transmission component 64, and the longer the distance the rack 642 moves up along the transmission cavity 6411, and the longer the length of the wire rope 627 that can be reeled in by the sleeve 621 on the side close to the center of gravity of the part, that is, the reeling length of the wire rope 627 is automatically adjusted according to the deflection angle of the part, thereby maintaining the horizontal state of the part during the lifting process.

[0039] A connecting beam 11 is provided on the main frame 1, and the beam trolley 4 is slidably connected to the connecting beam 11. The beam trolley 4 is used to drive the electric hoist 5 to move left and right. The fixing mechanism 2 includes an upper fixed beam 21 and a lower fixed beam 22. The main frame 1 is slidably connected to the upper fixed beam 21 and the lower fixed beam 22. The active trolley 3 is slidably connected to the lower fixed beam 22. The active trolley 3 is used to drive the main frame 1 to move forward and backward along the upper fixed beam 21 and the lower fixed beam 22.

[0040] The connecting beam 11 is used to provide a moving track for the beam trolley 4. The upper fixed beam 21 and the lower fixed beam 22 of the fixing mechanism 2 are used to be fixed on the corresponding wall to provide a stable working environment for the entire device. The active trolley 3 cooperates with the beam trolley 4 to drive the electric hoist 5 to move forward, backward, left and right, thereby meeting the lifting requirements at different positions.

[0041] The working principle of the present invention is as follows: when the part deflects to one side during lifting, it indicates that the force-bearing component 62 on the deflected side is close to the center of gravity of the part, that is, the tension on the wire rope 627 on this side is greater than that on the other side. In the initial state, the adjusting shaft 622 does not rotate, and the sleeve 621 located on the outer side of the adjusting shaft 622 will deflect to the same side under the action of the tension of the wire rope 627, thereby driving the arc-shaped sliding block 623 connected to the clamping block 626 to slide along the arc-shaped sliding groove 6221 to one side, and the tension spring 624 is stretched by force. The pressure regulating piston 625 slides along the liquid storage chamber 6222 under the drive of the arc-shaped sliding block 623, thereby pressing the hydraulic oil in the liquid storage chamber 6222 into the through flow channel 6223, thereby driving the adjusting component 63 to move. The greater the angle of deflection of the part to one side, the greater the angle of deflection of the sleeve 621 on this side on the adjusting shaft 622, and the pressure regulating piston 625 is pressed. The more hydraulic oil flows into the through flow channel 6223, the more hydraulic oil flows into the guide groove 6311 through the distribution plate 636, the longer the distance the first piston 632 moves to the other side along the guide groove 6311, the longer the distance the iron core 634 is inserted into the coil 637, the greater the magnetic force of the electromagnet composed of the coil 637 and the iron core 634, and according to the principle of like charges repel each other, the greater the repulsive force exerted on the repelling magnet 635, and the longer the distance the second piston moves along the guide groove 6311. Under the force transmission of the hydraulic oil, the rack 642 will be pushed to move upward along the transmission cavity 6411, the return spring 643 will be compressed, and the gear 6224 will rotate counterclockwise, thereby driving the adjusting shaft 622 to rotate, thereby driving the sleeve 621 on the side close to the center of gravity of the part to reel in the wire rope 627, thereby shortening the length of the wire rope 627 on the deflected side of the part.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
