Problems solved by technology

There are various problems in the current common helicopter transport wheels of skid landing gear, such as the heavy weight of the hydraulic transport wheels, which is not easy to disassemble, and the ordinary transport wheels are easy to fall off during transportation or unreasonable and variable and easily damaged. Wait
[0003] Common single-wheel transport wheels or single-wheel transport wheels, when loading and using, there are many changes, such as lack of steering or flexibility. Therefore, a helicopter that is light, easy to disassemble, reliable in transportation, and not easy to deform and damage is needed The transport wheel ensures the safe and efficient operation of helicopter transport

Embodiment 1

[0032] A helicopter transportation system of the present embodiment includes two sets of front transport wheels 2, two sets of rear transport wheels 3, and four corresponding mounting brackets 4 that are fixedly connected to the skids of the helicopter;

[0033] The front transport wheel includes a portal front wheel frame 21, two straight wheels 22 correspondingly arranged on both sides of the front wheel frame, and a front wheel rod 23 fixedly connected with the front wheel frame. One end of the rod is formed with a support rod 24 that is rotatably matched with the mounting frame, and the other end is provided with a hook 25, and the end is lifted upwards;

[0034] The rear transport wheel includes a rear wheel frame 31, two steering wheels 32 correspondingly arranged on both sides of the rear wheel frame, and a rear wheel rod 33 fixedly connected with the rear wheel frame, one end of the rear wheel rod. A support rod 34 is formed to be rotatably matched with the mounting fr...

Embodiment 2

[0040] Preferably, in order to improve the positioning of the UAV in the width direction and prevent sideslip, the bottom of the portal front wheel frame is formed with a groove for inserting the skid therein to prevent sideslip. The bottom of the rear wheel frame is provided with a side baffle 36 on the outer side of the bottom support of the skid to prevent the skid from sliding sideways, and mounting holes are provided under the cantilevers on both sides of the rear wheel frame to assemble the universal wheel, the side plate is located between the two universal wheels to achieve anti-skid.

[0041] The front wheel rod, the rear wheel rod and the support rod are located above the bottom support of the skid correspondingly, and the mounting frame is fixed on the top of the bottom support, and then cooperates with the bottom support through the support rod. Or the straight wheel is the fulcrum, and the bottom support is lifted up and hooked by the lever principle, so as to rea...

Embodiment 3

[0044] Wherein, the mounting frame 4 includes two connecting ears for fixing with the sliding sled by bolts and a sleeve fixedly connecting with the upper part of the connecting lugs, the sleeve is perpendicular to the length direction of the sliding sled and Level. Preferably, the support rod is provided with a shaft sleeve to further reduce the rotational friction and facilitate pressing and lifting. At the same time, the mounting seat is located at the two ends of the bottom support of the sliding sled, and the hook corresponds to the middle of the bottom support Hook, this design can effectively move the fulcrum outward, reduce the pressing force requirement, and fold the front wheel rod and the rear wheel rod under the fuselage, which can avoid the occupation of external space and improve the convenience of transportation.

Abstract

The invention discloses a helicopter transportation system and transportation method. The helicopter transportation system comprises two groups of front transportation wheels and two groups of rear transportation wheels as well as four mounting frames correspondingly and fixedly connected with a skid of the helicopter; each group of front transportation wheels comprise a portal front wheel frame,two straight-going wheels oppositely arranged at two sides of the front wheel frame and a front wheel rod fixedly connected with the front wheel frame. The transportation system of the invention is simple in structure, convenient to process and mount and has a long maintenance period; the frames are produced by welding conventional sectional bars, and the wheels are inflatable wheels conventionalin the market; and the weight is light, and two transportation wheels can be carried by one person. The size is small, thereby facilitating the transportation and storage; the cost is low, compared with the wheels with hydraulic apparatuses, the cost is greatly reduced, and the processing material cost is low; the use is convenient, and the wheels of the helicopter with a weight greater than 600 kg and less than one ton can be installed by one person.

Description

technical field [0001] The invention belongs to the technical field of transportation devices, and in particular relates to a helicopter transportation system and a transportation method. Background technique [0002] The problem of difficult transportation of helicopters has attracted more and more attention, especially helicopters with skid-mounted landing gear. At present, the common helicopter transport wheels with skid-type landing gear have various problems, such as the heavy weight of the hydraulic transport wheels and inconvenient disassembly, the common transport wheels falling off easily or being damaged by unreasonable and volatile forces during transportation, etc. Wait. [0003] Common single-wheel transport wheels or single-wheel transport wheels have more and more constants during loading and use, such as lack of steering or flexibility. Therefore, a helicopter that is light, easy to disassemble, reliable for transportation, and not easy to deform and damage ...
