Description

Technical Field

[0001] The utility model relates to the field of air cushion vehicles, in particular to a flat-plate remote-controlled driven air floating platform vehicle. Background Art

[0002] Air cushion vehicle is the abbreviation of air cushion suspension transporter. Air cushion suspension transporter uses the effect of gas film technology to lift and move the load. It is widely used in the aviation field to transport precision or overweight instruments, such as transporting spacecraft to the launch pad. The most important thing is to save effort, and the handling force only needs 0.5% of the load. This means that only one kilogram of force is needed to carry two tons of weight. This type of transporter is particularly suitable for heavy loads that are not easy to move flexibly, and large precision equipment that cannot withstand vibration and has high requirements for stability.

[0003] Most existing air-cushion vehicles use ordinary guide wheels, which are not active enough in guiding and react slowly during guiding. After the vehicle body completes the turning, some ordinary guide wheels fail to turn in the appropriate direction in time, causing the guide wheels to be dragged on the ground in an unrotated state, causing wear of the guide wheels. There is also a risk that the worn guide wheels will be damaged when the air-cushion vehicle is moving, affecting the normal use of the air-cushion vehicle. Utility Model Content

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] See also Figures 1 to 8 A flat-plate remote-controlled air-floating platform vehicle comprises an air-floating platform 1 and a mounting plate 3. An assembly groove 17 is provided on the bottom surface of the air-floating platform 1. An air-collecting block 14 is installed on the side wall of the assembly groove 17. A joint 15 is connected to the top of the air-collecting block 14. An air cushion 4 is installed on the bottom surface of the mounting plate 3. A plurality of interfaces 16 connected to the air cushion 4 are installed on the top of the mounting plate 3. A crossbeam and reinforcing ribs in contact with the top surface of the crossbeam are installed inside the assembly groove to enhance the strength of the air-floating platform 1. A plurality of annular protrusions are installed on the side of the interface 16. A plurality of through holes matching the interfaces 16 are provided at the bottom of the air-collecting block 14, and a plurality of annular grooves are provided on the inner wall of the through hole. When the mounting plate 3 and the air-collecting block 14 are assembled, after the interface 16 is inserted into the through hole provided on the air-collecting block 14, the mounting plate 3 is fixed while facilitating the disassembly of the mounting plate 3 by means of the clamping connection between the protrusion on the interface 16 and the groove in the through hole.

[0025] Electric control valves 5 are installed on the sides of both sides of the air flotation platform 1. The electric control valves 5 are connected to the joints 15. The flow of external gas is controlled by the electric control valves 5. The air cushion 4 is inflated through the gas collecting block 14. The gas film technology is used to lift and move the load, so that the air flotation platform 1 loaded with heavy objects is easier to move. Threaded cylinders 6 are installed on the sides of both ends of the air flotation platform 1. Assembly boxes 2 are installed on the sides of both ends of the air flotation platform 1. There are four threaded cylinders 6 and they are evenly divided into two groups and are symmetrically arranged on the sides of both ends of the air flotation platform 1. In combination with on-site needs, multiple air flotation platforms 1 can be connected by means of threaded rods and threaded cylinders 6 to extend the length of the air flotation platform 1. At the same time, two symmetrically arranged threaded grooves are provided on the sides of both ends of the air flotation platform 1. The threaded grooves are used for the installation of the assembly box 2, and the threaded grooves are arranged between the two threaded cylinders 6, so that the installation position of the assembly box 2 on the sides of both ends of the air flotation platform 1 can be located between the two threaded cylinders 6. The threaded cylinders 6 and the assembly box 2 do not interfere with each other and do not affect their respective use.

[0026] like Figure 4 and Figure 6As shown, a mounting groove 7 is provided on one side of the bottom surface of the assembly box 2, and two electric cylinders 12 are symmetrically installed on the top of the inner part of the mounting groove 7. The output ends of the two electric cylinders 12 are commonly installed with a mounting plate 13, and a shock absorber 8 is installed at the bottom of the mounting plate 13. There are four shock absorbers 8 and they are symmetrically distributed at the bottom of the mounting plate 13. The use of the shock absorber 8 makes the air floating platform 1 move more smoothly. A connecting seat 9 is installed at the moving end of the shock absorber 8. Combined with the figure, a sliding rod penetrating the connecting seat 9 is installed at the bottom of the mounting plate 13, and a differential wheel set 10 is installed at the bottom of the connecting seat 9. The differential wheel set 10 consists of a differential wheel type AVG steering wheel and a follower wheel, as shown in FIG. Figure 3 and Figure 4 As shown, pads 11 are installed at the four top corners of the air flotation platform 1. The pads 11 extend out of the top corners of the air flotation platform 1, and the extended parts are rounded, so that the pads 11 can play a buffering and protective role to prevent the top corners of the air flotation platform 1 from being damaged or causing damage to surrounding facilities when they are hit.

[0027] When the utility model is in use, the air cushion 4 is inflated through the electric control valve 5. After the air cushion 4 is completely inflated, the air cushion 4 lifts up the air floating platform 1. With the action of the electric cylinder 12 inside the mounting groove 7, the assembly plate 13 is driven to move downward, so that the differential wheel set 10 is in contact with the ground. The air floating platform 1 is driven to move and the steering of the air floating platform 1 is controlled by the differential wheel set 10. At the same time, during the movement of the air floating platform 1, the air floating platform 1 moves more smoothly through the action of the shock absorber 8. When the air cushion leaks during the use of the air floating platform 1, it can be supported near the faulty air cushion with the help of a jack. Since the mounting plate 3 and the air collecting block 14 are connected in a card-type form, the mounting plate 3 can be quickly removed for replacement.
