Description

Remote-controlled air cushion transport vehicle Technical Field

[0001] This utility model relates to the field of freight equipment technology, and in particular to a remote-controlled air cushion transport vehicle. Background Technology

[0002] The principle of air cushion transport is that when the air cushion is inflated, the air bladder expands to form a ring. Air enters the air chamber through small holes in the air bladder, establishing air pressure within the air chamber, and then leaks outwards to form a very thin air film with the ground. Because the air film has low frictional resistance, a very small thrust can be used to propel, rotate, and position heavy objects in any direction.

[0003] Existing air cushion transport vehicles often require manual pushing to move the objects being transported, ensuring directional adjustment during transport. Patent No. 201811364067.8 discloses a vacuum suction cup type air cushion transport vehicle traction device, which connects the traction vehicle and the air cushion vehicle using a traction vehicle and a suction cup device. However, this solution has limited load-bearing capacity due to the suction cup method, and stability cannot be guaranteed when transporting heavy materials. Furthermore, this solution does not disclose the traction method of the traction vehicle, leaving its traction flexibility unknown. Summary of the Invention

[0004] Technical objective: In order to overcome the shortcomings of the existing technology, this utility model provides a remote-controlled air cushion transport vehicle, which realizes flexible towing of the air cushion transport vehicle.

[0005] Technical solution: To achieve the above objectives, this utility model discloses a remote-controlled air cushion transport vehicle, including a tractor, a cargo air cushion vehicle, and a traction connection structure for connecting the tractor and the cargo air cushion vehicle. The traction connection structure includes a first trailer mounted on the tractor and a second trailer mounted on the cargo air cushion vehicle, wherein the first trailer and the second trailer are hinged together.

[0006] Furthermore, the first trailer includes a counterweight module and a traction link disposed on the counterweight module, and the end of the traction link away from the counterweight module is provided with a through hole for hinged connection with the second trailer.

[0007] Furthermore, the second trailer is configured as a U-shaped structure, the bottom wall of the U-shaped structure is fixedly connected to the cargo air cushion vehicle, the open end of the U-shaped structure faces the first trailer, and through holes are provided on both sides of the U-shaped structure for hinged connection with the traction link.

[0008] Furthermore, the traction link extends into the second trailer, and pins are inserted into the first and second through holes.

[0009] Furthermore, the tractor includes a frame and a loading platform and a traveling mechanism respectively disposed above and below the frame. The loading platform is used to connect the counterweight module, and the traveling mechanism is symmetrically arranged in two sets. The traveling mechanism includes wheels, a drive motor, and a chain drive assembly connecting the wheels and the drive motor.

[0010] Furthermore, the chain drive assembly includes a drive sprocket and driven sprockets disposed on both sides of the drive sprocket. The drive sprocket and the two driven sprockets are respectively connected by two chains. The output end of the drive motor drives the drive sprocket to rotate through a drive shaft, and the drive shaft is rotatably connected to the frame.

[0011] Furthermore, there are two wheels, and the two wheels are rotatably connected to the frame via driven shafts and the two driven sprockets respectively.

[0012] Furthermore, the loading platform is rotatably connected to the vehicle frame via a rotating assembly. The rotating assembly includes a turntable, and a coaxial fixing pin is fixedly installed at the center of the turntable. The protruding end of the fixing pin is rotatably installed in a central hole opened on the vehicle frame.

[0013] Furthermore, it also includes a wireless remote control system for the movement control of the tractor (1).

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model relates to a remote-controlled air cushion transport vehicle. Through the use of two cooperating trailers (Trailer 1 and Trailer 2), it achieves convenient connection and disassembly between the tractor and the air cushion transport vehicle. Utilizing two sets of motor-driven walking mechanisms, when the two motors work synchronously, the tractor can travel in both directions (forward and backward); when the two motors work asynchronously, the tractor can rotate 360° in both directions. Combined with a rotating component, this allows the walking mechanism to freely steer without the loading platform turning, resulting in greater site adaptability and suitability for various working conditions and confined spaces. Equipped with a wireless remote control system, it enables remote control, is simple and convenient to operate, and is safe and efficient. Attached Figure Description

Detailed Implementation

[0022] The principles and features of this utility model are described below with reference to Figures 1 to 5. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] A remote-controlled air cushion transport vehicle includes a tractor 1, a cargo air cushion vehicle 2, and a traction connection structure for connecting the tractor 1 and the cargo air cushion vehicle 2. The cargo air cushion vehicle 2 is used to carry materials to be transported, and the tractor 1 is used to traction the cargo air cushion vehicle 2. After the cargo air cushion vehicle 2 is inflated, its airbag forms a very thin air film with the ground. Due to the low frictional resistance of the air film, heavy objects can be moved in any direction with a very small thrust. Air cushion vehicles are existing technology and will not be described in detail here.

[0024] The traction connection structure includes a first trailer 3 and a second trailer 4 that cooperate with each other, and are hinged together by a pin 9. The first trailer 3 is mounted on the tractor 1, and the second trailer 4 is mounted on the cargo air cushion vehicle 2.
