Method used

Referring to accompanying drawing 1, air cushion vehicle is made up of traction bar 1, car body 2, fixed crawler-type air-cushion 3, guided crawler-type air-cushion 4, leg 5 and guide wheel 6 etc. The fixed crawler-type air cushion 3 is directly connected with the vehicle body 2, and the guided crawler-type air cushion 4 adds end bearings on the basis of the fixed crawler-type air cushion 3, and then connects with the vehicle body. The air cushion described below uses the fixed crawler belt Formula air cushion 3 is based on launching. The steering control fork is arranged on the crawler-type air cushion 4 of guiding, is connected with drawbar 1 by connecting rod. Guide wheel 6 is installed on a cantilever beam under the car body, is pressed on the ground by certain elastic force, prevents the transport vehicle from laterally slipping in moving.
Referring to accompanying drawing 2-Fig. 5, the novel crawler-type air cushion of the present application is the design after carrying out innovation to above-mentioned air cushion, and it is made of air cushion chamber 12, air cushion installation frame 8, crawler belt 7, crawler belt support roller 9 and support roller Fra...

Abstract

The invention provides an air cushion structure and an air cushion carrier vehicle, which not only utilize the advantages of an air cushion but also are free from special treatment for plant ground. According to the air cushion structure provided by the invention, an air cushion chamber is encircled by an annular crawler belt and an aerated air cushion is pressed on a rubber crawler belt all the time. The air cushion structure has the advantages that the demand of a crawler belt air cushion on the ground is greatly reduced; the air cushion structure is suitable for the transportation of various cement and asphalt ground; the ground is only required to be relative even and the demand on smoothness is low; the expensive cost of polishing treatment for the plant ground is reduced; and the economic benefit is increased.

Example Embodiment

[0019] See attached figure 1 The air-cushion transport vehicle is composed of a traction rod 1, a car body 2, a fixed crawler-type air cushion 3, a guided crawler-type air cushion 4, a foot 5 and a guide wheel 6 and so on. The fixed crawler air cushion 3 is directly connected to the car body 2. The guided crawler air cushion 4 adds an end bearing to the fixed crawler air cushion 3, and then connects to the car body. The air cushion described below is a fixed crawler The type air cushion 3 is based on deployment. There is a steering fork on the guided crawler air cushion 4, which is connected with the traction rod 1 through a connecting rod. The guide wheel 6 is installed on a cantilever beam under the vehicle body and pressed against the ground by a certain elastic force to prevent the transport vehicle from sliding laterally during movement.
[0020] See attached Figure 2-Figure 5 The new crawler air cushion of the present application is an innovative design of the above air cushion, and it is composed of an air cushion chamber 12, an air cushion mounting frame 8, a crawler belt 7, a crawler belt support roller 9 and a support roller frame 10, etc. The air-cushion mounting frame 8 is a mouth-frame-shaped structure. In this embodiment, the mouth-frame-shaped structure is composed of rigid structural plates. The air-cushion chamber 12 is installed on the lower middle structural plate of the air-cushion mounting frame through a ball joint 15 , The crawler belts 7 along the crawler 16 on both sides pass through the gap of the mouth frame structure of the air-cushion mounting frame 8 to surround the air-cushion chamber 12. The endless crawler is tensioned by four crawler support rollers 9; the support rollers 9 of the crawler are fixed by bearings 18 On the support roller frame 10, the support roller frame 10 has an elongated hole 11, and the distance between the rollers can be adjusted by adjusting bolts, so that the tension of the crawler belt 7 can be adjusted to ensure that the air cushion 12 does not leak after being inflated. The air-cushion chamber 12 and the air-cushion mounting frame 8 are connected by a ball joint 15 so that each air-cushion is freely rotatable relative to the air-cushion fixing part, and has strong adaptability to the ground.
[0021] See attached Image 6 , The crawler support roller 9 is composed of a roller shaft, a round tube and a nylon sleeve on the outside. A bearing 18 is nested between the track support roller 9 and the roller mounting frame 10 to ensure that the roller can rotate easily and freely. See attached Figure 4 , The two sides of the crawler belt 7 are provided with side edges 16 that are turned up. The side edges are embedded in the annular positioning grooves 17 at both ends of the supporting roller 9 to ensure that the crawler belt 7 will not slip off when rotating.
[0022] See attached Figure 4 with 5 When the air-cushion vehicle of the present application is in use, each air-cushion is connected to the air-distribution adjustment unit through the air-cushion inflation joint 13 and the soft high-pressure air pipe. The operator can adjust the air pressure of each air-bag through the handheld hammer-type remote control assembly to make The air cushions are all suspended. There is a layer of air film between the air cushion 12 and the crawler 7, and the operator can tow the air cushion vehicle with a small amount of force. The body 2 drives the air cushion 12 to move, and the part of the crawler 7 touching the ground is relatively stationary and moves forward on the body 2 At time, the crawler 7 pulls the crawler support roller 9 to rotate, and the crawler and wheel similar to a tank are the same.
[0023] figure 1 The front of the air-cushion transport vehicle is equipped with two guide air cushions 4, which are connected with the vehicle body through end bearings, and the rear of the transport vehicle is two fixed air cushions 3. When turning, the operator swings the traction rod 1 and transmits the steering force to the steering fork guided to the air cushion 4 through the connecting rod. At this time, the air-cushion mounting frame 8, the crawler support roller 9 and the support roller frame 10 in the guide air cushion 4 pull the crawler to twist and deform. Since the material of the crawler is very soft, the vehicle can turn after deformation.
[0024] Because of the crawler, it is possible for the air-cushion vehicle to move on the ground with low smoothness, small gaps, and discontinuity, which solves the limitation that traditional air cushion can only move on smooth, continuous and dense roads, greatly Expanded the scope of use of air cushions, greatly increasing the plant floor area where air cushions can be applied. The inter-plant transportation can also be realized with the vehicle body's own air source, which is a breakthrough to the existing air cushion transportation technology.
