Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

First embodiment

Referring to fig. 4, fig. 4 is a schematic view of a conventional manual hydraulic truck. When the truck is empty, the truck itself is very light in weight and therefore has negligible friction with the ground. However, when the hydraulic truck is used for weighing, the weight carried by the pallet is generally of a heavy mass, and a large relative force will occur between the wheel set of the hydraulic truck and the ground. If the locking takes place for the wheelset, then the friction on hydraulic pressure car and ground becomes sliding friction from the rolling friction of wheelset easily, and the organic terrace of the grit bits that will greatly wear and tear of adhesion on the wheelset causes the damage of terrace paint curing layer. For solving above-mentioned technical problem, this embodiment provides a gas suspension carrier based on suspension fan.

Referring to fig. 1 and 2, in a basic embodiment, in order to realize the basic functions of the air-suspension truck, the following improvements are made on the basis of the existing hydraulic truck:

first, the conventional hydraulic carrier lifts a fork arm through a hydraulic system to further separate a tray from the ground, and then a control handle drags a wheel set to move, so that the carrier and the ground slide.

This application chooses the air suspension system to realize the separation on tray and ground for use, consequently, suspension fan 7 and air cushion apron 12 are necessary in this application scheme.

The air cushion apron 12 belongs to a common component in an air cushion vehicle (ship), and comprises an air inlet part and an air outlet part. Usually, the air inlet part is connected with the air outlet of the suspension fan 7 through an airflow channel; the air outlet part is generally arranged at the bottom of the vehicle. When the air flow generated by the suspension fan 7 continuously flows into the air cushion skirt 12 from the air inlet portion of the air cushion skirt 12, the air first fills the air cushion skirt 12, and then the surplus air is continuously discharged from the air outlet portion of the air cushion skirt 12. The hydraulic lifting part of the hydraulic truck can be replaced as long as the selected suspension fan 7 can provide enough wind power and a layer of air film is formed between the air cushion apron and the ground.

To the problem that the gas suspension leads to the raise dust easily, because the suspension carrier of this application is designed to the high dust-free workshop of environmental cleanliness, consequently form the gas that the gas film caused and can not cause the raise dust in the environment.

The suspension fan 7 is installed on the vehicle body 6 of the air suspension truck. The suspension fan 7 is connected with the air inlet part of the air cushion apron 12 through an air flow channel. As shown in fig. 1, the airflow channel is formed by communicating a suspension fan ventilation duct 8, a ventilation duct inside the yoke 15, and a ventilation hose 13. Of course, the air flow passage may not be provided inside the yoke 15, as would be apparent to a person skilled in the art.

On the other hand, when suspension carrier does not bear the weight of (when suspension fan 7 is out of work), for avoiding carrier bottom and ground friction each other on the one hand, for making yoke 15 get into the tray bottom more easily on the one hand, automobile body 6, yoke 15 and the wheelset of current hydraulic carrier have been kept to this embodiment. The wheel set in this example comprises an auxiliary rear wheel 5, an auxiliary middle wheel 11 and an auxiliary front wheel 14. In order to make the stress of each wheel uniform and make the centre of gravity fall into the middle of the carrier when the carrier is unloaded, the auxiliary rear wheel 5 is arranged at the lower part of the tail end of the fork arm 15, the auxiliary middle wheel 11 is arranged at the lower part of the middle section of the fork arm 15, and the auxiliary front wheel 14 is arranged at the lower part of the front end of the fork arm 15.

When the suspended transport vehicle adopts a design similar to a manual hydraulic transport vehicle as shown in fig. 1 and 2, the product of the application can also reserve the control handle 1 of the manual transport vehicle. Typically, the control handle 1 is connected to the auxiliary rear wheel 5 by two mutually orthogonal revolute pairs. When a user applies traction to the grip portion of the control handle, the control handle 1 transmits the traction to the vehicle body 6 to actuate the vehicle body 6 to move.

Further, in order to improve the flexibility of the levitation transport vehicle of the present invention, a battery 4 and a controller 3 may be mounted on a vehicle body 6 of the transport vehicle. At this moment, the carrier can meet the energy supply requirement and can independently complete the cargo carrying work. In this design, the battery 4, the controller 3, and the levitation fan 7 are electrically connected.

Further, the battery 4 may be of a detachable accumulator design. When the battery power of the suspension transport vehicle is used up, the transport vehicle with the used-up energy can be quickly charged only by detaching the battery 4 for replacement.

In general, in order to maintain balance during transportation of the hydraulic truck, at least two forks 6 should be provided, and the forks 6 are arranged in a parallel manner and the distance between them can be adjusted so as to be inserted into a loading tray. When the number of the fork arms 6 is two, the fork arms can be arranged in a mirror symmetry mode; when the number of the fork arms 6 is more than or equal to three, the fork arms are always arranged in a linear array mode when the distance between the fork arms is adjusted, and the carrying vehicle is in a mirror symmetry mode on the whole. In order to keep the body of the suspension truck balanced, the fork arms 6 should also be arranged in the manner described above.

Second embodiment

The product of the present application will be described in detail below with reference to the accompanying drawings:

as shown in fig. 1, an electro-hydraulic truck in a storage system includes a steering handle 2, a truck body 6, and a yoke 15; the direction handle 2 is provided with a control handle 1 for controlling the starting and closing of the whole carrier, and the control handle 1 is also provided with an indicator lamp for displaying the electric quantity of the storage battery; the vehicle body is provided with a controller 3, a detachable storage battery 4, an auxiliary rear wheel 5 and a suspension fan 7, and a suspension fan ventilating duct 8 is arranged at an air outlet of the suspension fan 7; a suspension fan ventilating duct is arranged in the fork arm 15, a plurality of air cushion aprons 12 and air cushion apron fixing cover plates 9, auxiliary middle wheels 11 and auxiliary front wheels 14 which are fixed with the air cushion aprons are arranged at the lower part of the fork arm 15, the air cushion apron fixing cover plates 9 are connected with the lower part of the fork arm 15 by universal bulbs 10, and a ventilation hose 13 which is connected with the suspension fan ventilating duct 8 and the air cushion aprons 12 is arranged at the same time.

The specific loading and unloading process comprises the following steps:

in the process of loading, a worker moves a fork arm 15 of the air suspension carrier to the position below a cargo tray, presses down a control switch on a control handle 1, a suspension fan 7 starts to work to release airflow with certain air pressure, the airflow enters an air cushion apron 12 through a suspension fan ventilating duct 8 and a ventilating hose 13, and after the air cushion apron 12 is filled with the airflow, the airflow is released to the ground to form a layer of air film, and the whole carrier is gradually lifted up to finish the loading work.

In the unloading process, after a worker moves the goods to a designated position, the worker presses a control switch on the control handle 1, the suspension fan 7 stops working, air flow in the air cushion apron 12 is gradually exhausted, the whole carrier gradually moves downwards until the auxiliary front, middle and rear wheels 14, 11 and 5 are in contact with the ground, and the worker moves away from the carrier to finish the unloading work.

The present invention is not limited by the above embodiments, and any other changes, modifications, replacements, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be all effective replacement modes, and all are included in the protection scope of the present invention.
