Detailed ways

Exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Here, it should be noted that, in the drawings, the same reference numerals are assigned to components having substantially the same structure and function, and redundant descriptions on components that are substantially the same are omitted in order to make the description more concise.

As shown in Figure 1, the universal automatic adjustment air cushion module includes a support plate 1, as shown in Figure 2 and Figure 3, a ball seat 21 is installed on the support plate 1, and a million To the ball head 22, the universal ball head 22 is connected with a connection seat 23 connected with the air cushion truck body, and a ball head stop device is installed on the ball head seat 21, and the ball head stop device includes the The universal ball head 22 is limited to the ball head gland 24 in the ball head seat 21, so that the universal ball head 22 can only rotate in the ball head seat 21, and can not produce a horizontal or vertical direction relative to the ball head seat 21. displacement. An air cushion airbag 3 is installed on the lower end surface of the support plate 1, and the air cushion airbag 3 is sealed and connected with the lower end surface of the support plate 1 through the flange 4; the air cushion airbag 3 is provided with a plurality of symmetrically distributed gas Overflow holes 31 , the gas overflow holes 31 are distributed on the air cushion airbag 3 in a ring shape. As shown in FIG. 4 , the support plate 1 is provided with an air inlet 11 communicating with the air cushion airbag 3 .

The ball seat 21 on the support plate 1 is provided with a plurality of support plates 12, and the support plates 12 are used to strengthen the strength of the support plate 1. In order to generate a burden and ensure the flexibility of the universal automatic adjustment air cushion module, an avoidance via hole 13 is provided on the support plate 12 .

The connecting seat 23 at the top of the universal ball head 22 is installed on the air cushion transport vehicle body of the air cushion transport vehicle. When the air cushion module is installed and used, the air pump is used to inflate the air cushion airbag 3 through the air inlet 11 on the support plate 1, and the air cushion The airbag 3 expands to form a ring, and the air-bearing pressure is established in the air-cushion airbag 3. The gas overflow hole 31 at the bottom of the air-cushion airbag 3 leaks outward, forming a very thin air film with the ground. Because the frictional resistance of the air film is small, it can be used A small thrust pushes, rotates, and positions the weight in any direction. When transporting objects on a horizontal plane, the support plate 1 is parallel to the ground. When encountering undulating ground, the universal ball head 22 and the ball head seat 21 on the support plate 1 rotate. At this time, the support plate 1 forms a certain angle with the horizontal plane until The air module rides over the undulations so that the air truck can move over the undulating ground.

Because the air cushion module has no friction with the ground and will not pollute the environment when it is in operation, it is widely used in pharmaceutical, chemical and other production plants that have high environmental requirements for moving, installing, and maintaining process equipment. It is also shockproof when transported with air cushions. The air cushion is a very light and mobile handling equipment. Generally, the air cushion can carry 10 tons of workpieces, and the weight is about 5 kg.

The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and changes will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to better explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention and design various embodiments with various modifications as are suited to the particular use.
