Description

Technical Field

[0001] The utility model relates to the technical field of transfer equipment, and in particular to a multifunctional tooling trolley for transferring unmanned aerial vehicles. Background Art

[0002] The tilt-rotor UAV is a new type of aircraft that combines the advantages of fixed-wing aircraft and helicopters. It has the ability to take off and land vertically, hover in the air, and cruise at high speed. When taking off and landing, the rotor shaft is perpendicular to the ground, presenting a horizontal helicopter flight state. When it reaches a certain speed, the rotor shaft can tilt forward 90° and become horizontal. The rotor is used as a pulling propeller. At this time, the tilt-rotor aircraft can fly long distances at a higher speed like a fixed-wing aircraft. During the testing phase, the tilt-rotor UAV needs to be transferred to the site multiple times, so staff often need to use a tooling cart to transport the UAV.

[0003] However, there are some problems with the existing technology: the existing tooling trolleys can generally only simply carry and transport drones, and during the drone testing phase, staff often need to fine-tune and maintain the drone's structure. The existing tooling trolleys are difficult to lift the drone to a suitable height, making it inconvenient for staff to inspect and maintain the lower part of the drone, reducing the work efficiency during the testing phase. Therefore, we propose a multifunctional tooling trolley for drone transportation. Utility Model Content

[0004] In response to the deficiencies in the existing technology, the utility model provides a multifunctional tooling trolley for transporting drones, which can quickly adjust the height of the drone, thereby facilitating the disassembly, assembly and maintenance work of the staff.

[0005] The purpose of the utility model is achieved as follows: a multifunctional tooling trolley for transporting drones, comprising a base, an armrest provided on the base, a lifting frame provided on the top of the base, the lifting frame and the base being connected by a lifting assembly, a first vibration damping assembly provided on the lifting frame, nylon wheels provided on both sides of the base, and the nylon wheels being connected to the base by a second vibration damping assembly.

[0006] Optionally, the lifting assembly includes a first support frame, both ends of the first support frame are hinged to the base and the lifting frame respectively, the middle part of the first support frame is hinged to a second support frame, both ends of the second support frame are rotatably connected to nylon bearing wheels, and the nylon bearing wheels at both ends of the second support frame are rollingly connected to the base and the lifting frame respectively, an ultra-high pressure electric hydraulic pump is fixedly installed on the base, a hydraulic cylinder is connected to the ultra-high pressure electric hydraulic pump, the hydraulic cylinder is hinged to the base, and the piston rod of the hydraulic cylinder is hinged to the second support frame.

[0007] Optionally, the first vibration reduction assembly includes a first damping rod, which is fixedly mounted on the inner wall of the lifting frame, a telescopic end of the first damping rod is fixedly connected to a buffer plate, an outer surface of the first damping rod is movably sleeved with a first spring, and both ends of the first spring are respectively fixedly connected to the lifting frame and the buffer plate.

[0008] Optionally, a rubber pad is fixedly mounted on the top of the buffer plate, and the width of the rubber pad is the same as the width of the buffer plate.

[0009] Optionally, the second vibration damping assembly includes a roller bracket, the roller bracket is fixedly mounted on the base, the nylon wheel is rotatably connected to the roller bracket, a second damping rod is fixedly mounted on the roller bracket, a second spring is movably sleeved on the outer surface of the second damping rod, and both ends of the second spring are fixedly connected to the roller bracket.

[0010] Optionally, angle steels are fixedly mounted on the top of the lifting frame, and the number of the angle steels is four, and the four angle steels are evenly distributed at the four corners of the top of the lifting frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model provides a lifting frame and a lifting assembly. The staff pushes the base and the lifting frame into the bottom of the drone's belly, and then uses the lifting assembly to move the lifting frame upward, thereby enabling the lifting frame to support the drone and allow the drone to stay at the required height, making it convenient for the staff to complete the disassembly, assembly, maintenance and other operations of the drone, thereby improving the overall work efficiency of the drone testing phase.

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides a multifunctional tooling trolley for transporting drones, comprising a base 1, an armrest 2 being provided on the base 1, a lifting frame 3 being provided on the top of the base 1, the lifting frame 3 and the base 1 being connected via a lifting assembly, a first vibration damping assembly being provided on the lifting frame 3, nylon wheels 4 being provided on both sides of the base 1, and the nylon wheels 4 being connected to the base 1 via a second vibration damping assembly.

[0024] Furthermore, the lifting assembly includes a first support frame 5, the two ends of the first support frame 5 are hinged to the base 1 and the lifting frame 3 respectively, the middle part of the first support frame 5 is hinged to the second support frame 6, both ends of the second support frame 6 are rotatably connected to nylon bearing wheels 7, and the nylon bearing wheels 7 at both ends of the second support frame 6 are rollingly connected to the base 1 and the lifting frame 3 respectively, an ultra-high pressure electric hydraulic pump 8 is fixedly installed on the base 1, the ultra-high pressure electric hydraulic pump 8 is connected to a hydraulic cylinder 9, the hydraulic cylinder 9 is hinged to the base 1, and the piston rod of the hydraulic cylinder 9 is hinged to the second support frame 6.

[0025] The staff pushes the base 1 and the lifting frame 3 into the bottom of the drone's belly, and then starts the ultra-high pressure electric hydraulic pump 8, so that the piston rod of the hydraulic cylinder 9 extends. As the piston rod continues to extend, it will drive the four nylon bearing wheels 7 to roll and the second support frame 6 to rotate, thereby driving the first support frame 5 to move together and make the lifting frame 3 move upward, so that the lifting frame 3 can support the drone. At the appropriate height, the pressure maintaining function of the ultra-high pressure electric hydraulic pump 8 is started to make the drone stay at the required height, making it convenient for the staff to complete the disassembly, assembly, maintenance and other operations of the drone.

[0026] Furthermore, the first vibration reduction assembly includes a first damping rod 10, which is fixedly mounted on the inner wall of the lifting frame 3. The telescopic end of the first damping rod 10 is fixedly connected to the buffer plate 17. The outer surface of the first damping rod 10 is movably sleeved with a first spring 11, and the two ends of the first spring 11 are respectively fixedly connected to the lifting frame 3 and the buffer plate 17.

[0027] When the lifting frame 3 supports the drone, the metal connector on the belly of the drone is supported by the first vibration damping assembly. Therefore, when the staff moves the cart to transport the drone, the first damping rod 10 and the first spring 11 can cooperate to reduce the vibration effect on the drone during the transportation process and prevent the drone from being damaged.

[0028] Furthermore, a rubber pad 12 is fixedly mounted on the top of the buffer plate 17 , and the width of the rubber pad 12 is the same as the width of the buffer plate 17 .

[0029] The design of the rubber pad 12 can effectively reduce the contact wear between the supporting surface of the buffer plate 17 and the metal connecting piece on the belly of the machine.

[0030] Furthermore, the second vibration damping assembly includes a roller bracket 13, the roller bracket 13 is fixedly mounted on the base 1, the nylon wheel 4 is rotatably connected to the roller bracket 13, a second damping rod 14 is fixedly mounted on the roller bracket 13, and a second spring 15 is movably sleeved on the outer surface of the second damping rod 14, and both ends of the second spring 15 are fixedly connected to the roller bracket 13.

[0031] When the trolley moves and the nylon wheel 4 rolls on an uneven road surface, the second damping rod 14 on the second vibration reduction assembly cooperates with the second spring 15 to further reduce the vibration impact on the drone during transportation, thereby improving the protection effect on the drone.

[0032] Furthermore, angle steels 16 are fixedly installed on the top of the lifting frame 3 . There are four angle steels 16 , which are evenly distributed at the four corners of the top of the lifting frame 3 .

[0033] When the lifting frame 3 supports the drone, the angle steel 16 is clamped on the side of the metal connector on the belly of the drone, so as to limit the position of the drone and prevent the drone from deviating and falling due to inertia during transportation.

[0034] The working principle and use process of this utility model:

[0035] First, the staff pushes the base 1 and the lifting frame 3 into the bottom of the drone's belly, so that the angle steel 16 is clamped on the side of the metal connector on the drone's belly, and then starts the ultra-high pressure electric hydraulic pump 8 to extend the piston rod of the hydraulic cylinder 9. As the piston rod continues to extend, it will drive the four nylon bearing wheels 7 to roll and at the same time rotate the second support frame 6, thereby driving the first support frame 5 to move together to make the lifting frame 3 move upward, and then the lifting frame 3 can support the drone. At the same time, the rubber pad 12 is attached to the metal connector on the belly. The staff can start the pressure maintaining function of the ultra-high pressure electric hydraulic pump 8 at an appropriate height to make the drone stay at the required height, which is convenient for the staff to complete the disassembly, assembly, maintenance and other operations of the drone. When transporting the drone, it is only necessary to push the base 1 to move through the handrail 2. During the transportation process, the first vibration reduction assembly and the second vibration reduction assembly can reduce the vibration impact on the drone during transportation, providing better protection for the drone.

[0036] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that, without departing from the principles of the present invention, a number of improvements and modifications may be made to the present invention by a person skilled in the art, and such improvements and modifications shall fall within the scope of protection of the claims of the present invention.
