Description

Technical Field

[0001] The utility model relates to the technical field of rail transit construction hoisting equipment, in particular to a hoisting equipment based on a drone group. Background Art

[0002] A drone is an aircraft that does not require a pilot to fly. It can be remotely controlled or fly autonomously. Drones come in a variety of designs and functions, ranging from small model aircraft to large military reconnaissance and attack aircraft, to aircraft for civilian and commercial purposes such as aerial photography, agricultural monitoring, and logistics distribution.

[0003] Drone lifting equipment refers to devices specially designed for drones to carry and lift heavy objects. These devices enable drones to lift, transport and release cargo in the air.

[0004] At present, the existing lifting equipment based on drone swarms cannot meet the requirements of quickly and accurately adjusting the height of the hoisted objects and automatically clamping and fixing them to prevent the hoisted objects from swinging or falling off during transportation, resulting in reduced safety and stability of the operation. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the height of the hoisted object cannot be adjusted quickly and accurately and the hoisted object cannot be automatically clamped and fixed to prevent the hoisted object from swinging or falling off during transportation, resulting in reduced safety and stability of the operation, and a lifting device based on a drone swarm is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A lifting device based on a drone swarm, comprising:

[0008] A drone body, wherein a fixing frame is fixedly arranged at the bottom of the drone body, and a through hole is opened at the center of the top of the fixing frame;

[0009] A lifting mechanism, which is arranged on a fixed frame and is used to drive the lifting object to rise and fall;

[0010] The clamping assembly is arranged on the drone body and the fixing frame and is used to clamp the hoisted object.

[0011] In a possible design, the lifting mechanism includes two mounting frames symmetrically fixed on both sides of the through hole of the fixing frame, the two mounting frames are rotatably provided with the same rotating rod on one side close to each other, and a drum is fixedly provided on the outside of the rotating rod, and a cable is wound on the outside of the drum, a motor is fixedly provided on one side of one of the mounting frames, one end of the motor output shaft is fixedly connected to the rotating rod, and a hook is fixedly provided on one end of the cable.

[0012] In a possible design, the clamping assembly includes two clamping frames symmetrically hingedly arranged on both sides of the bottom of the fixing frame, the bottom ends of the two clamping frames are hingedly provided with clamping plates, connecting frames 1 are fixedly arranged on both sides of the bottom of the drone body, electric push rods are hingedly arranged on the inner sides of the two connecting frames 1, connecting frames 2 are fixedly arranged on the tops of the two clamping frames, and the output ends of the two electric push rods are respectively hinged to the two connecting frames 2.

[0013] In a possible design, a stopper is hingedly provided on the inner side of the hook, a spring is fixedly provided on one side of the stopper, and the other side of the spring is fixedly connected to the hook, and one side of the stopper is abutted against the opening of the hook through the spring.

[0014] In a possible design, hook grooves are provided on the sides of the clamping frame and the clamping plate that are close to each other, and the same tension spring is hooked inside the two hook grooves. Anti-slip stripes are provided on the other side of the clamping plate.

[0015] In a possible design, the bottom of the drone body is symmetrically and detachably provided with two supporting legs, and rubber sleeves are fixedly provided on the outside of the two supporting legs.

[0016] In one possible design, a GNSS receiver, an attitude sensor, and a wireless communication module are electrically disposed on the inner side of the drone body, and a high-definition camera is embedded on one side of the drone body.

[0017] In a possible design, one end of the cable with a hook passes through a through hole of the fixing frame and extends to the bottom thereof.

[0018] In this application, when starting to use, first check whether the driving equipment such as motors and electric push rods are in normal working condition, and whether the battery of the drone body is sufficient. Then confirm that the electronic equipment such as GNSS receivers, attitude sensors and wireless communication modules are turned on and connected to the drone control system, ensure that the high-definition camera image is clear, and then start the drone through the drone control system, use the GNSS receiver for precise positioning, ensure that the drone flies above the target hoisting object, use the high-definition camera to shoot and transmit the real-time image to the ground control center, so that the operator can confirm the location of the hoisting object and the surrounding environment;

[0019] When the drone flies above the target hoisting object, the motor is started, and the output shaft of the motor drives the rotating rod to rotate, thereby driving the drum to rotate and releasing the cable. The hook on the cable gradually descends as the cable is released. When the cable is released to a suitable length, the staff hooks the hoisting object through the hook. When the hoisting object is hooked on the hook, the stopper on it is pushed by the spring and counteracts the opening of the hook, which can prevent the hoisting object from accidentally falling off. Then the motor is started to rotate in the opposite direction, so that it drives the rotating rod to drive the drum to rotate in the opposite direction. The reverse rotation of the drum drives the cable to wind, thereby driving the hoisting object hooked on it to gradually rise. When the hoisting object rises to a suitable position, the electric push rod is controlled to extend by the drone control system. The output end of the electric push rod pushes the two clamping frames to move in a direction close to each other through the connecting frame 2. When the two clamping frames move, the clamping plates on them move in the direction of the hoisting object until the two clamping plates clamp the hoisting object. The anti-slip stripes can increase the friction between the clamping plate and the hoisting object to prevent the hoisting object from slipping.

[0020] The drone then adjusts its flight attitude according to the feedback from the attitude sensor and maintains a steady ascent. After rising to a suitable position, the drone flies to the designated location carrying the hoisted object. During this period, the drone maintains contact with the ground control center through the wireless communication module to transmit the flight status and hoisted object information in real time. After arriving at the designated location, the drone hovers stably and controls the electric push rod to retract and release the clamping plate. At this time, the motor is controlled to rotate and the cable is released to make the hoisted object on the hook descend and be placed at the target position.

[0021] After completing the lifting task, the drone returns to the starting point or lands in a safe area according to the predetermined route. After landing, the rubber sleeves on the supporting legs are in contact with the ground, which can provide a certain cushioning effect and reduce vibration and noise during landing.

[0022] The utility model has the following beneficial effects:

[0023] The utility model can drive the rotating rod and the drum to rotate by setting the lifting mechanism and controlling the forward and reverse rotation of the motor, thereby realizing the retraction and release of the cable, and then hooking the hoisting object through the hook fixed at one end of the cable, realizing the adjustment of the hoisting height, facilitating the hooking and fixing of the hoisting object, and at the same time, being able to quickly and accurately adjust the height of the hook hoisting object, thereby reducing the time of manual handling or adjustment;

[0024] In the utility model, through the setting of the clamping assembly, when the hoisted object rises to a suitable position, the UAV control system controls the electric push rod to extend, and the output end of the electric push rod pushes the two clamping frames to move towards each other through the connecting frame 2. When the two clamping frames move, the clamping plates thereon are driven to move in the direction of the hoisted object until the hoisted object is clamped, which can effectively prevent the hoisted object from swinging or falling off during transportation;

[0025] The utility model can quickly and accurately adjust the height of the hoisted object through the coordinated setting between the lifting mechanism and the clamping assembly, which greatly reduces the time of manual handling and adjustment; and the clamping assembly automatically clamps and fixes the hoisted object after it reaches the predetermined position, effectively preventing it from swinging or falling off during transportation, ensuring the safe transportation of the hoisted object, which not only improves the working efficiency, but also significantly enhances the safety and stability of the operation.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Embodiment 1

[0033] Reference Figure 1-4 , a lifting device, comprising:

[0034] The drone body 1 (model: XLP-Z100) serves as a carrier of the entire device, and a fixing frame 8 with a through hole in the center is fixedly installed at its bottom. The through hole is used for the passage of the cable 11 to facilitate the release and retraction of the cable 11.

[0035] The lifting mechanism includes two mounting frames 9 symmetrically fixedly installed on both sides of the through hole of the fixing frame 8, and the same rotating rod is rotatably arranged between the two mounting frames 9. A drum 10 is fixedly arranged on the outside of the rotating rod, and the drum 10 is used to wind the cable 11. A motor 14 is fixedly installed on the side of one of the mounting frames 9, and the output shaft of the motor 14 is fixedly connected to the rotating rod. By controlling the forward and reverse rotation of the motor, the rotating rod and the drum 10 can be driven to rotate, thereby realizing the retraction and release of the cable 11. A hook 12 is fixedly arranged at one end of the cable 11 to realize the adjustment of the hoisting height, which is convenient for hooking and fixing the hoisting object. At the same time, the height of the hooked hoisting object can be adjusted quickly and accurately, reducing the time for manual handling or adjustment.

[0036] The clamping assembly includes two clamping frames 15 symmetrically hinged on both sides of the bottom of the fixing frame 8, and a clamping plate 19 is hinged at the bottom end of each clamping frame 15. When the clamping frame 15 moves to clamp the hoisted object, the clamping plate 19 will move so that the entire clamping plate 19 can fully contact the hoisted object, thereby increasing the stability of the clamping of the hoisted object. A connecting frame 16 is fixed to each side of the bottom of the drone body 1, and an electric push rod 18 is hinged on the inner side of each connecting frame 16. At the same time, a connecting frame 2 17 is fixed to the top of each of the two clamping frames 15, and the output end of the electric push rod 18 is hinged to the connecting frame 2 17. By controlling the extension and retraction of the electric push rod 18, the opening and closing of the clamping frame 15 can be driven to clamp and release the hoisted object, which can effectively prevent the hoisted object from swinging or falling off during transportation.

[0037] The present application can be used in the technical field of lifting equipment based on drone swarms, and can also be used in other fields applicable to the present application.

[0038] Embodiment 2

[0039] On the basis of embodiment one, embodiment two also includes: a lifting device based on drone swarms, which is applied to the technical field of lifting devices based on drone swarms, a block 13 is hinged on the inner side of the hook 12, and the block 13 is connected to the hook 12 through a spring and always maintains a slight pressure on the hook opening. This design can ensure that the hoisted object will not fall off accidentally during the lifting process, thereby improving safety.

[0040] A hook groove is provided on the side where the clamping frame 15 and the clamping plate 19 are close to each other, and the same tension spring 20 is hooked in the two hook grooves. The function of the tension spring 20 is to keep the clamping plate 19 in the initial position when there is no external force, and to play a certain limiting role to prevent the clamping plate 19 from shaking on the clamping frame 15. At the same time, the setting of the tension spring 20 does not affect the clamping operation of the clamping plate 19 on the hoisting object. At the same time, an anti-slip stripe 21 is provided on the other side of the clamping plate 19 to increase the friction during clamping and prevent the hoisting object from slipping.

[0041] Two support legs 6 are symmetrically and detachably installed at the bottom of the drone body 1. A rubber sleeve 7 is fixed to the outside of each support leg 6. After the drone body 1 lands, the contact between the rubber sleeve 7 on the support leg 6 and the ground can provide a certain buffering effect and reduce vibration and noise during landing.

[0042] The drone body 1 is electrically equipped with a GNSS receiver 2 (model: T300plus), an attitude sensor 3 (model: SINDT) and a wireless communication module 4 (model: WL-4032). These components work together to ensure that the drone can accurately navigate, fly stably, and communicate with the ground control center or other drones through wireless signals.

[0043] A high-definition camera 5 (model: RER-USB4KCAM30GH) is embedded on one side of the drone body 1 for real-time shooting and transmission of images of the hoisting operation site, facilitating remote monitoring and command.
