Description

Technical Field

[0001] The utility model belongs to the technical field of aerial working devices, and in particular relates to an aerial working device with an active retractable hook. Background Art

[0002] With the continuous development of aerial work device technology, aerial work devices are increasingly used in logistics and transportation, agricultural plant protection, aerial photography, rescue missions and other fields. Automation and intelligence have become an inevitable trend. Aerial work devices are easily affected by solar radiation, weather systems, terrain and ground temperature. Therefore, in addition to landing and taking off at a dedicated parking area, aerial work devices generally hover at an altitude of 5-50 meters above the ground to avoid ground turbulence areas and descend to the ground through slings to complete transportation tasks. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the purpose of the utility model is to provide an aerial working device with an active retractable hook.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an aerial working device with an active retractable hook, comprising: a carrier, a telescopic module and an active grab hook module; the active grab hook module is connected to the bottom of the carrier through the telescopic module; the telescopic module comprises a traction member and a storage component, the storage component is installed under the carrier, the traction member extends outward from the storage component until it is connected to the active grab hook module; a power balancing component is installed above the active grab hook module, and the power balancing component dynamically levels the active grab hook module, thereby improving the grabbing accuracy of the active grab hook module.

[0005] Its main working principle is that after the carrier takes off, the active grab module is lifted by the telescopic module. When the carrier moves to the target area, the telescopic module controls the height of the active grab module by adjusting its own length. When the active grab module reaches the target height, it clamps the object. However, since the active grab module is installed under the carrier, it will sway due to the influence of the airflow under the carrier, thus affecting the stability of the grab. It is necessary to install a dynamic balance component above the active grab module, and use the dynamic balance component to dynamically level the active grab module to offset the influence of the airflow under the carrier on the active grab module.

[0006] Preferably, the power balancing assembly comprises a balancing bracket and a power member;

[0007] A through hole is provided in the middle of the balancing bracket, and the traction member passes through the through hole to be connected with the active grabber module;

[0008] At least three groups of the power members are provided, and at least three groups of the power members are horizontally distributed on the balance bracket.

[0009] Preferably, the balancing bracket is a planar bracket, and at least three groups of installation cavities are arranged on the periphery of the planar bracket. The at least three groups of installation cavities are distributed around the through hole with the through hole as the center, and a group of the power parts are installed in each group of the installation cavities.

[0010] Preferably, the balancing bracket is an end bracket, and the end bracket is vertically installed above the active grabber module;

[0011] The outer wall of the end face bracket is provided with at least three mounting surfaces, and the at least three mounting surfaces are circumferentially distributed on the outer wall of the end face bracket, and a group of power parts are installed on each mounting surface.

[0012] Preferably, the balancing bracket is a columnar bracket, and the columnar bracket is vertically installed above the active grabber module;

[0013] Support rods are provided on both sides of the columnar bracket, and the support rods on both sides are radially arranged on the outer wall of the columnar bracket; mounting parts are provided on both sides of the ends of the support rods, and the mounting parts on both sides are horizontally arranged, and a group of power parts are installed on each of the mounting parts, and the two groups of power parts on the support rod on the same side are arranged opposite to each other.

[0014] Preferably, the storage assembly is a storage box, a roller is provided in the storage box, the traction member is a traction rope, one end of the traction rope is connected to the roller, and the other end of the traction rope is connected to the active grab hook module; the rotation of the roller drives one end of the traction rope to wrap around the surface of the roller.

[0015] Preferably, the storage assembly is a storage hole, and the traction member is a telescopic rod, one end of the telescopic rod is placed in the storage hole, and the other end of the telescopic rod is interconnected with the active grab hook module.

[0016] Preferably, the active grab hook module includes a base, a control motor, a clamping arm and a lifting rod; the base is connected to the telescopic module; the end of the clamping arm is meshed with the threaded end of the control motor, the control motor is installed in the base, one end of the lifting rod is connected to the base, and the other end of the lifting rod is connected to the clamping arm; the number of the clamping arms is provided in at least three groups, at least three groups of the clamping arms are distributed in a circle with the base as the center, and the number of the lifting rods corresponds to the number of the clamping arms.

[0017] Preferably, the active grab hook module includes a power supply, which is installed in the base and connected to the control motor.

[0018] Preferably, the carrier is a drone or a manned aircraft.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The carrier and the active grab hook module are connected through the telescopic module. When the carrier moves to the target area, the active grab hook module is needed to grab the object. During this process, the height of the active grab hook module is adjusted by the telescopic module. Compared with directly controlling the height of the carrier, this method allows the carrier to work in a safer and more open area, making the operation more flexible.

[0021] 2. By installing a power balance component above the active grab hook module, the power balance component dynamically levels the active grab hook module, thereby offsetting the impact of the airflow under the carrier on the active grab hook module, allowing the active grab hook module to have a more stable working environment. Compared with existing drone grab hooks, it has better stability and effectively improves the grasping accuracy.

[0022] 3. By combining the telescopic module and the power balancing component, after adding the lifting function, when the telescopic module is in the unfolded state, the airflow influence below it will increase. However, since a power balancing component is added on the basis of the telescopic structure, the influence is reduced to a controllable range, making the device more practical.

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Embodiment 1,

[0032] This embodiment specifically discloses an aerial working device with an active retractable hook, such as Figure 1-Figure 2 As shown, it includes a carrier 1, a telescopic module 2 and an active grab module 3; the active grab module 3 is connected to the bottom of the carrier 1 through the telescopic module 2; when the carrier 1 takes off, the active grab module 3 is lifted by the telescopic module 2 to fly to the target area. When the carrier 1 reaches the target area, the active grab module 3 is located below the target area. At this time, the telescopic module 2 is controlled to scale, so that the active grab module 3 below the carrier 1 rises or falls above the object. Then the active grab module 3 will clamp the object. At this time, the telescopic module 2 can be contracted to drive the active grab module 3 to rise, or the carrier 1 can directly fly upward to take the object away, and the grabbing operation can be completed.

[0033] Specifically, the telescopic module 2 includes a traction member 20 and a storage component 21, wherein the storage component 21 is installed under the carrier 1, and the traction member 20 extends outward from the storage component 21 until it is connected to the active grab hook module 3, wherein the traction member 20 is responsible for connecting the active grab hook module 3, and the storage component 21 is responsible for controlling the length of the connection between the traction member 20 and the active grab hook module 3. By adjusting this length, the height of the active grab hook module 3 can be adjusted. During the adjustment process, the excess part of the connecting member will be stored in the storage component 21.

[0034] At the same time, during the operation, since the active grabber module 3 is installed below the carrier 1, in order to obtain sufficient lift during takeoff, the carrier 1 needs a large airflow to support it below the carrier 1, but the active grabber module 3 will be affected by the strong airflow and shake left and right, affecting the accuracy of the operation. Therefore, a power balance component 4 is installed above the active grabber module 3. When the active grabber module 3 is affected by the airflow, the power balance component 4 starts to dynamically level the active grabber module 3, so that the active grabber module 3 can remain in a relatively stable area for operation.

[0035] Among them, the power balancing component 4 includes a balancing bracket 40 and a power piece 41; a through hole 400 is provided in the middle of the balancing bracket 40, and the traction piece 20 passes through the through hole 400 to be connected with the active grab hook module 3, ensuring that the power balancing component 4 will not affect the movement of the traction piece 20; in order to allow the balancing bracket 40 to maintain a balanced state, at least three groups of power pieces 41 are provided, and at least three groups of power pieces 41 are horizontally distributed on the balancing bracket 40, ensuring that the power balancing component 4 maintains force balance all around.

[0036] When the balancing bracket 40 is a plane bracket 401, at least three groups of installation cavities 402 are arranged on the periphery of the plane bracket 401, and at least three groups of installation cavities 402 are distributed on the periphery of the through hole 400 with the through hole 400 as the center of the circle, and a group of power parts 41 are installed in each group of installation cavities 402. As shown in the figure, the surface of the plane bracket 401 is a square, and installation cavities 402 are arranged on the four corners of the square, and the opening of the installation cavity 402 faces downward, and a propeller is installed in each installation cavity 402 as a power part 41. When the power balancing component 4 starts to start, the four propellers will start at the same time to provide lift for the four corners of the plane bracket 401. When the power balancing component 4 senses that the airflow under the carrier 1 affects the active grabber module 3, the active grabber module 3 will be kept in a stable area by adjusting the lift ratio between each propeller.

[0037] In addition, the storage assembly 21 is a storage box, and a roller is provided inside the storage box. The traction member 20 is a traction rope, one end of which is connected to the roller, and the other end of which is connected to the active grab hook module 3; the rotation of the roller drives one end of the traction rope to be wound around the surface of the roller. When the roller rotates, the excess part of the traction rope can be wound and stored, shortening the length of the traction rope, thereby raising the height of the active grab hook module 3; the wound part can also be lowered to increase the length of the traction rope. Thereby lowering the height of the active grab hook module 3.

[0038] Further, such as Figure 2 As shown, the active grab module 3 includes a base 30, a control motor 31, a clamping arm 32 and a lifting rod 33; the base 30 is connected to the telescopic module 2; the end of the clamping arm 32 is provided with a tooth pattern, which is meshed with the threaded rod of the driving end of the control motor 31, the control motor 31 is installed in the base 30, one end of the lifting rod 33 is connected to the base 30, and the other end of the lifting rod 33 is connected to the rotating shaft of the clamping arm 32. When the control motor 31 is started, it will drive the clamping arm 32 to rise or fall along the rotating shaft of the lifting rod 33, so as to open or tighten the clamping arm 32; in order to clamp the object, the number of the clamping arms 32 is set to at least three groups, at least three groups of clamping arms 32 are distributed around the base 30 as the center, the number of lifting rods 33 corresponds to the number of clamping arms 32, and the object is clamped by multiple groups of clamping arms 32. In addition, the active grab module 3 also includes a power supply 34, which is installed in the base 30 and connected to the control motor 31 to provide power to the control motor 31.

[0039] Furthermore, the carrier 1 is an unmanned aerial vehicle or a manned aircraft.

[0042] Among them, Figure 3 As shown, the balance bracket 40 is an end bracket 403, which is vertically mounted above the active grabber module 3; the outer wall of the end bracket 403 is provided with at least three mounting surfaces 404, which are circumferentially distributed on the outer wall of the end bracket 403, and a group of power components 41 are mounted on each mounting surface 404. Specifically, the power component 41 is a jet power device, whose port faces outward, and when the power balance component 4 senses that the airflow below the carrier 1 affects the active grabber module 3, the active grabber module 3 is kept in a stable area by adjusting the air output of each jet port.

Specifically, the power member 41 is a roller-propelled power device, and when the power balancing component 4 senses that the airflow under the carrier 1 affects the active grabber module 3, it will keep the active grabber module 3 in a stable area by adjusting each rolling speed.
