DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0030] In view of the problems existing in the prior art, an embodiment of the present invention provides a hanging cutting device based on a drone, such as Figure 1 As shown, the suspended cutting device based on the drone includes a drone body 1, the bottom wall of the drone body 1 is provided with two placement racks for supporting the drone body 1 to be placed on a platform, and a cutting mechanism 2 provided on the bottom plate of the drone body 1, the cutting mechanism 2 is used to cut the cutting piece, not limited to the cutting of metal plates, iron houses and metal frames.

[0031] In one example, Figure 2 As shown, the cutting mechanism 2 includes a storage box 21 for storing batteries and an inert gas source (not limited to nitrogen), the storage box 21 is fixedly arranged on the bottom plate of the drone body 1, and a support tube 22 is connected to the bottom plate of the storage box 21, and the lower end of the support tube 22 is arranged higher than the lower end surface of the placement frame, so that the drone body 1 can be parked stably on the platform and the drone body 1 can be prevented from tilting when parked. A laser assembly 23 is movably arranged in the support tube 22, and a first drive assembly 24 and a second drive assembly 25 for connecting the first drive assembly 24 and the laser assembly 23 are arranged in the support tube 22. When working, the first drive assembly 24 drives the combination of the second drive assembly 25 and the laser assembly 23 to move in the support tube 22, and the second drive assembly 25 drives the laser assembly 23 to move relative to the first drive assembly 24. The above-mentioned structure can achieve the effect of dual-channel movement.

[0032] In this embodiment, the first drive component 24 carries the laser component 23 downward to make the first movement, and at the same time, the second drive component 25 carries the laser component 23 to make the second movement relative to the first drive component 24. It is worth noting that the first movement and the second movement are carried out simultaneously. The first movement and the second movement can not only make the laser component 23 move quickly to the outside of the support tube 22, but also extend the distance between the laser component 23 and the drone body 1 during cutting, thereby protecting the drone body 1 during cutting.

[0033] In one embodiment, Figure 3 As shown, the first driving component 24 includes a driving cylinder 241 fixedly arranged in the support tube 22, a connecting line is connected to the driving cylinder 241, a free end of the connecting line is fixedly connected to the battery, and a driving end (which can be understood as the lower end) of the driving cylinder 241 is connected to a cylinder arm 242, and the cylinder arm 242 is suspended in the support tube 22.

[0034] In one embodiment, Figure 3 and Figure 4As shown, the second driving assembly 25 includes a supporting block 251 movably mounted outside the cylinder arm 242, and the supporting block 251 is fixedly mounted on the side wall of the push plate 252, specifically fixed on the left side, and is arranged near the top of the push plate 252. The lower end of the push plate 252 is fixedly connected to the laser assembly 23, and the side wall (which can be understood as the left side wall) of the push plate 252 is fixedly connected with a second spur rack 259, and the second spur rack 259 is meshed with the second gear 258, and the second gear 258 is fixedly mounted outside the rotating rod 257, and the rotating rod 257 is movably plugged into the cylinder arm 242. It should be understood that the rotating rod 257 can only perform rotational movement on the cylinder arm 242, and cannot perform horizontal left and right movement. One end of the rotating rod 257 away from the push plate 252 (which can be understood as the left end) is slidably arranged with the inner wall of the support tube 22, and a first gear 255 is fixedly sleeved outside the rotating rod 257. The first gear 255 is meshed with a first spur rack 256, and the first spur rack 256 is fixedly arranged on the inner wall of the support tube 22.

[0035] During operation, the first drive component 24 moves downward with the combined structure of the second drive component 25 and the laser component 23. During this movement, the second drive component 25 also drives the laser component 23 to move downward relative to the first drive component 24. In this way, the laser component 23 can be quickly moved out of the support tube 22 through two-step downward movement. Specifically, after the driving cylinder 241 is started, it will drive the cylinder arm 242 to move downward in the support tube 22. The movement of the cylinder arm 242 will bring the combined structure of the second driving component 25 and the laser component 23 downward; at the same time, when the cylinder arm 242 moves downward, it will bring the rotating rod 257 and the first gear 255 downward. Due to the meshing relationship between the first gear 255 and the first spur rack 256, when the cylinder arm 242 moves downward, the first gear 255 will rotate. The rotation of the first gear 255 will bring the rotating rod 257 to rotate. The rotation of the rotating rod 257 will also bring the second gear 258 to rotate. The rotation of the second gear 258 will bring the push plate 252 downward relative to the cylinder arm 242 through the second spur rack 259, so that the laser component 23 will move downward relative to the cylinder arm 242 under the drive of the push plate 252. During this movement, the support block 251 can play a supporting role, so that the push plate 252 can only move along the length direction of the cylinder arm 242, and can always ensure that the cylinder arm 242 and the push plate 252 are in a parallel state.

[0036] In one embodiment, Figure 3As shown, the second driving assembly 25 also includes a sliding block 253 fixedly arranged on the side wall of the cylinder arm 242 (which can be understood as the right side wall), and the sliding block 253 and the push plate 252 are slidably connected to each other. In this embodiment, the sliding block 253 and the supporting block 251 cooperate with each other to further support the push plate 252, so that the push plate 252 can always maintain vertical movement. The upper end surface of the sliding block 253 is fixedly connected with a first telescopic member 254, the upper end of which is fixedly connected to the lower end surface of the supporting block 251, the first telescopic member 254 comprises a first telescopic rod 2541, a first telescopic tube 2542 and a first telescopic spring 2543, the first telescopic rod 2541 is movably inserted in the first telescopic tube 2542, the first telescopic spring 2543 is wound around the outside of the first telescopic rod 2541, one end of the first telescopic spring 2543 is fixedly set on the side wall of the first telescopic rod 2541, and the other end of the first telescopic spring 2543 is fixedly connected to the outer side wall of the first telescopic tube 2542. In this embodiment, the first telescopic member 254 can play a supporting and guiding role, and at the same time, can provide a reset force for the reset process of the push plate 252.

[0037] In one embodiment, Figure 5 As shown, the laser assembly 23 includes a protective box 231 fixedly arranged on the lower end of the push plate 252. Preferably, the push plate 252 is fixed on the middle part of the outer top wall of the protective box 231. A through hole 232 is provided on the bottom plate of the protective box 231. A laser head 233 is arranged just above the through hole 232. The laser head 233 is connected to a laser emitter 235. The laser emitter 235 is fixedly arranged on the upper end surface of a fixed plate 234. The fixed plate 234 is movably arranged in the protective box 231. A wire 236 is connected to the laser emitter 235. The free end of the wire 236 is fixedly connected to the battery. When working, the laser emitter 235 is started, and the laser emitted by the laser emitter 235 is output through the laser head 233 for cutting.

[0038] The laser emitter 235 and the laser head 233 are both precision instruments. When not in operation, in order to avoid long-term exposure to the external environment, the laser emitter 235 and the laser head 233 are arranged in the protective box 231. At the same time, in order to ensure that the laser head 233 can extend out of the protective box 231 through the through hole 232 when in operation, in one embodiment, as Figure 5As shown, the drone-based suspended cutting equipment also includes a pushing component 3, which is used to push the laser head 233 out of the protective box 231 when working, and reset the laser head 233 into the protective box 231 when not working, so as to protect it. The pushing component 3 includes a supporting plate 31 fixedly arranged on the lower end surface of the fixed plate 234, and the supporting plate 31 is movably arranged in the protective box 231. A moving rod 33 is fixedly arranged on the upper end surface of the supporting plate 31, and the moving rod 33 is movably plugged into the top plate of the protective box 231 and the sliding block 253. The upper end of the moving rod 33 is fixedly connected to a pushing block 32. In this embodiment, the structural design of the pushing component 3 is reasonable, and the laser head 233 can be controlled to extend out of the protective box 231 without an external power source. Specifically, As the supporting block 251 continues to slide downward on the cylinder arm 242, it will form a resistance to the pushing block 32. Under the action of the resistance force, the moving rod 33 will move downward through the pushing block 32. The downward movement of the moving rod 33 will move the combined structure of the laser head 233, the fixing plate 234 and the laser emitter 235 downward through the supporting plate 31, so that the laser head 233 extends out of the protective box 231. The downward movement of the laser head 233 stops when the supporting block 251, the pushing block 32 and the sliding block 253 conflict with each other.

[0039] like Figure 5 As shown, a plurality of second telescopic members 34 are fixedly arranged on the upper end surface of the support plate 31, and the free ends of the second telescopic members 34 are fixedly connected to the inner top plate of the protection box 231. The second telescopic members 34 can be used to guide and support the support plate 31 so that the support plate 31 can only move in the vertical direction. At the same time, when the push block 32 loses the downward resistance force, the support plate 31 can be driven to reset upward, and the laser head 233 can be retracted into the protection box 231 through the support plate 31, so as to protect the laser head 233. The second telescopic member 34 includes a second telescopic rod 341, a second telescopic cylinder 342, and a second telescopic spring 343. The second telescopic rod 341 is movably inserted in the second telescopic cylinder 342, and the second telescopic spring 343 is wound outside the second telescopic rod 341, and the two ends of the second telescopic spring 343 are respectively fixedly connected to the side wall of the second telescopic rod 341 and the outer side wall of the second telescopic cylinder 342.

[0040] During the cutting process of the laser head 233, waste will be generated, and the existence of the waste will affect the cutting process. In order to solve the above problem, in one embodiment, as shown in FIG. Figure 5As shown, the suspended cutting equipment based on the drone also includes a purge mechanism 4, which is used to purge the waste generated by the laser head 233 during cutting to prevent the waste from affecting the cutting efficiency of the laser head 233. The purge mechanism 4 includes a supercharger 41 fixedly arranged on the upper end surface of the fixed plate 234, and the supercharger 41 is used to store inert gas and can also pressurize the inert gas so that the inert gas can be ejected. The supercharger 41 is connected to a connecting hose 42, and the free end of the connecting hose 42 is connected to the inert gas source, and the connecting hose 42 is arranged in the support tube 22. A purge head 43 is fixedly connected to the bottom plate of the supercharger 41, and the purge head 43 is connected to the inner cavity of the supercharger 41, and the lower end of the purge head 43 is arranged directly above the through hole 232, and the purge port at the lower end of the purge head 43 is bent toward the laser head 233. This arrangement can ensure that the purge direction of the purge head 43 is directly opposite to the cutting position of the laser head 233.

[0041] The purge mechanism 4 in this embodiment has a reasonable structural design and can realize synchronous movement with the laser head 233. This arrangement is intended to ensure that the lower end of the purge head 43 can always face the cutting position of the laser head 233 to achieve high-efficiency purge. When working, when the laser emitter 235 is started, the supercharger 41 will also start working. The operation of the supercharger 41 will extract inert gas through the connecting hose 42 and pressurize the inert gas, so that the pressurized inert gas is ejected from the purge head 43 to clean the waste on the cutting position of the laser head 233.

[0042] In order to make the start and stop of the laser emitter 235 and the booster 41 more intelligent, in one embodiment, Figure 6As shown, the drone-based hanging cutting device also includes a control mechanism 5, which is used to intelligently control the start and shut down of the laser emitter 235 and the supercharger 41. It is worth noting that the start and shut down control process does not require manual operation, and the control mechanism 5 can be completed automatically. Specifically, the control mechanism 5 includes a first electrode contact 51 fixedly arranged on the lower end surface of the support plate 31, and a second electrode contact 52 is arranged directly below the first electrode contact 51. In this embodiment, when the first electrode contact 51 and the second electrode contact 52 are in contact, the laser emitter 235 and the supercharger 41 will be controlled to start, and when the first electrode contact 51 and the second electrode contact 52 are separated, the laser emitter 235 and the supercharger 41 will be controlled to shut down. Specifically, when working, the movement of the support plate 31 in the protective box 231 will bring the first electrode contact 51 to move closer to or away from the second electrode contact 52. In the above movement process, the first electrode contact 51 and the second electrode contact 52 can be contacted or separated. It should be noted that, in this embodiment, the separation of the first electrode contact piece 51 and the second electrode contact piece 52 is achieved by the upward driving force provided by the driving cylinder 241 .

[0043] In one example, Figure 6 As shown, the second electrode contact piece 52 is fixedly arranged on the upper end of the resistance rod assembly 53, and the resistance rod assembly 53 is movably inserted in the movable through hole 54. A second spring 55 is wound around the outside of the resistance rod assembly 53, and the two ends of the second spring 55 are respectively fixedly connected to the side wall of the resistance rod assembly 53 and the inner bottom wall of the protection box 231. In this embodiment, the second electrode contact piece 52 can move up and down in the protection box 231. Specifically, as the protection box 231 approaches the cutting piece, the resistance rod assembly 53 will move the second electrode contact piece 52 upward for a certain distance under the resistance of the cutting piece. After the second electrode contact piece 52 contacts the first electrode contact piece 51, the laser emitter 23 5 will cut off the part to be cut. When the part to be cut is cut and falls off downward, it will lose the resistance to the resistance rod assembly 53 (it should be understood that before cutting, the lower end of the resistance rod assembly 53 is controlled to resist the part to be cut). At this time, driven by the second spring 55, the resistance rod assembly 53 will make a reset movement downward. The downward movement of the resistance rod assembly 53 will drive the second electrode contact piece 52 to separate from the first electrode contact piece 51, the series circuit is disconnected, and the laser emitter 235 and the booster 41 stop working. In this embodiment, the separation of the second electrode contact piece 52 and the first electrode contact piece 51 is achieved because the part to be cut loses the resistance to the resistance rod assembly 53 after the cutting is completed.

[0044] It is worth noting that the two separation processes of the second electrode contact sheet 52 and the first electrode contact sheet 51 can be set simultaneously or separately, which will not be described in detail here.

[0045] In one example, Figure 7 As shown, the resisting rod assembly 53 includes a first resisting rod 531 and a second resisting rod 532. A movable rod 533 is fixedly arranged on the lower end of the first resisting rod 531, and a movable groove 534 is provided on the upper end of the second resisting rod 532. The movable rod 533 is movably inserted into the movable groove 534. A first spring 535 is wound around the movable rod 533. The two ends of the first spring 535 are respectively fixedly connected to the side wall of the movable rod 533 and the upper end surface of the second resisting rod 532. The arrangement of the resisting rod assembly 53 in this embodiment can realize the extension and contraction of the length in the vertical direction. On the one hand, when the first electrode contact sheet 51 and the second electrode contact sheet 52 are in contact, it can buffer the impact force, thereby protecting the first electrode contact sheet 51 and the second electrode contact sheet 52. On the other hand, it can make the first electrode contact sheet 51 and the second electrode contact sheet 52 contact for a longer time, thereby making the cutting process more complete.

[0046] In one embodiment, Figure 8 and Fig. 9 As shown, the first electrode contact sheet 51 and the second electrode contact sheet 52 further include a cooling mechanism 6 , which is used to cool the laser head 233 to prevent the laser head 233 from being overheated, thereby protecting the laser head 233 . The cooling mechanism 6 includes a cooling ring 61, which is movably sleeved outside the laser head 233, and a vertical rod 62 is fixedly arranged on the upper end surface of the cooling ring 61, and the upper end of the vertical rod 62 is fixedly arranged on the lower end surface of the supporting plate 31. A gas cavity 64 with a ring-shaped structure is opened inside the cooling ring 61, and a conducting pipe 63 is fixedly inserted on the cooling ring 61, and the other end of the conducting pipe 63 is fixedly inserted on the purge head 43, and the conducting pipe 63 is used for connecting the purge head 43 and the gas cavity 64. A plurality of first holes 65 are arranged on the bottom plate of the cooling ring 61, and a plurality of concentric circle structures are formed in the horizontal direction. Such an arrangement can cool different parts of the laser head 233, and the direction of the cooling gas forms an angle with the laser head 233, such as Fig. 9 The lower end of the first hole 65 is disposed toward the laser head 233, and a plurality of second holes 66 are provided on the side wall of the cooling ring 61 toward the laser head 233. The cooling gas direction at the second holes 66 is disposed perpendicular to the laser head 233. Fig. 9 shown.

[0047] During operation, part of the gas in the purge head 43 is introduced into the gas cavity 64 through the conducting tube 63 , and cools different parts of the laser head 233 through the first hole 65 and the second hole 66 .

[0048] In one example, Fig.10 As shown, the cooling ring 61 includes a ring body 611, and a rotating hole (unnumbered) connected to the gas cavity 64 is opened on the lower end of the ring body 611. A sealing plate 612 is movably arranged in the rotating hole. In this embodiment, the sealing plate 612 can rotate in the rotating hole, so that it can rotate with the first hole 65, so that the contact point between the cooling gas and the laser head 233 changes, and the laser head 233 can be contacted in a larger range, thereby making the cooling process of the laser head 233 more efficient.

[0049] In one embodiment, Fig.10 and Fig.11 As shown, the suspended cutting device based on the drone also includes a rotation drive mechanism 7, which is used to drive the blocking plate 612 to rotate in the rotation hole. The rotation drive mechanism 7 includes a first ring 71 fixedly arranged on the top wall of the gas cavity 64, a rotating shaft 72 is fixedly sleeved outside the first ring 71, a second ring 73 is fixedly sleeved outside the rotating shaft 72, a third ring 76 is fixedly arranged on the lower end surface of the second ring 73, a fixed seat 77 is fixedly arranged at the lower end of the third ring 76, and the fixed seat 77 is fixedly arranged on the upper end surface of the blocking plate 612, and a plurality of inclined grooves 74 are opened on the circumference of the second ring 73, preferably, the plurality of inclined grooves 74 are arranged in an equidistant annular shape. The rotation drive mechanism 7 also includes a guide tube 75, one end of which is fixedly connected to the side wall of the gas cavity 64, and the other end of which is slidably connected to the second ring 73, and the guide tube 75 is used for the communication between the conduction tube 63 and the inclined groove 74.

[0050] In this embodiment, the rotational drive mechanism 7 provides a rotational force for the sealing plate 612 without the need for an external power source, thereby greatly reducing production costs. Specifically, the inert gas in the conducting tube 63 will be conducted into the inclined groove 74 through the guide tube 75, and under the action of the pressurized gas, it will push the second ring 73 to rotate counterclockwise. The rotation of the second ring 73 will cause the sealing plate 612 to rotate through the third ring 76 and the fixed seat 77.

However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
