Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle transportation, in particular to a maintenance equipment and tool conveying device based on an unmanned aerial vehicle. Background Art

[0002] The maintenance equipment and tool conveying device is a kind of equipment that has been gradually widely used in the field of modern industrial maintenance, especially in the industries of complex mechanical systems, aerospace, shipbuilding, automobile manufacturing and maintenance. These industries involve a large number of high-precision and high-value equipment and systems, so maintenance work becomes particularly important. Traditional maintenance methods often require maintenance personnel to manually carry and replace maintenance equipment and tools, which is not only inefficient, but also may increase the labor burden and safety risks of maintenance personnel. Even if vehicles are used to transport tools in time, there will be problems such as how to transport the required maintenance equipment, tools, and equipment to the maintenance site because vehicles cannot be transported under field conditions, so drones are used to transport maintenance equipment and tools to the maintenance site. However, temporary maintenance equipment and tools are generally bundled on drones with cloth, ropes, boxes, etc. for transportation, so that during the transportation process, the maintenance equipment and tools may fall off the drone due to shaking, and there are certain safety hazards. For this reason, we propose a maintenance equipment and tool conveying device based on drones. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, 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 creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-7A maintenance equipment and tool conveying device based on a drone includes a drone 5, an upper box assembly 1 for storing and transporting parts, a lower box assembly 2 for storing and transporting parts, an automatic hook assembly 3 for hanging materials, a support rod assembly 4 and a connecting assembly 6. The bottom of the drone 5 is provided with an upper box assembly 1, the upper box assembly 1 is fixedly installed above the lower box assembly 2, the bottom of the lower box assembly 2 is provided with an automatic hook assembly 3, the four hanging corners of the lower box assembly 2 are provided with support rod assemblies 4, and the bottom of the drone 5 is provided with a connecting assembly 6.

[0028] The upper box assembly 1 includes an upper box frame 101 and a box cover 102. The box cover 102 is connected to the upper box frame 101 through hinges and buckles. Inclined surfaces are provided on both sides of the upper box frame 101. The bottom surface of the upper box frame 101 is combined with the top surface of the box of the lower box assembly 2.

[0029] The lower box assembly 2 includes a lower box frame 201, two box covers 202, four support rod mounting tubes 203 and two tensioning screws 204. The bottom of the lower box frame 201 has a frame welded from 20x20x1 square tubes. The lower box frame 201 is a sheet metal structure welded on the bottom frame. The two box covers 202 are respectively located on the front and rear sides of the lower box frame 201. The box covers 202 are connected to the lower box frame 201 through hinges and buckles. The four support rod mounting tubes 203 are welded to the lower box frame 201. The two support rod mounting tubes 203 on the same side are connected by tensioning screws 204 to play a role of tightening and reinforcement.

[0030] The support rod mounting tube 203 is tilted, and the support rod assembly 4 is inserted into the inside of the support rod 203. Two threaded holes are provided on the mounting tube of the support rod 203. The threaded holes are internally threaded with set screws, which press against the support rod assembly 4. The support rod assembly 4 can be adjusted and fixed by using them together.

[0031] The automatic hook assembly 3 includes a movable hook 301, a fixed hook 302, a reset spring 303, a screw 1 304, and a screw 2 305.

The two screws 2 305 connect the reset spring 303 to the movable hook 301 and the fixed hook 302 respectively. When the automatic hook assembly 3 is used to hang and transport materials, the movable hook 301 is moved in the direction close to the fixed hook 302. At this time, the reset spring 303 is stretched and basically in a vertical state. Due to the principle of mechanical self-locking, the movable hook 301 cannot be loosened under the tension of the reset spring 303, so that the hanging function is realized. When the materials are transported to the destination, a force is applied to the movable hook 301 in the direction away from the fixed hook 302 at the moment when the materials touch the ground. Under the tension of the reset spring 303, the movable hook 301 is automatically loosened, so that the function of automatic falling of the materials is realized.

A fixed column 604 is fixedly installed at one end of the two support plates 602. A movable plate 603 is movably connected to the middle end of the two fixed columns 604. A scissor spring 605 is fixedly installed on the outer surface of the two fixed columns 604. The two ends of the scissor spring 605 are fixedly installed on the support plate 602 and the movable plate 603. 3, four fixed blocks 606 are fixedly installed on the bottom of the drone 5, four universal balls 607 are movably installed on the bottom of the four fixed blocks 606, the bottoms of the four universal balls 607 are fixedly installed on the tops of four connecting sleeves 608, and the bottoms of the four connecting sleeves 608 are movably installed with support rod assemblies 4 through set screws, respectively. By placing the inclined surface of the upper box frame 101 on the support plate 602, the upper box frame 101 is restricted on the support plate 602 by the movable plate 603 to prevent it from falling, and then the support rod assembly 4 is installed on the connecting sleeve 608 by the set screws, the drone 5 can lift the upper box assembly 1 and the lower box assembly 2 storing the maintenance equipment and transport them to the designated location.
