Automatic leveling control device for air cushion suspended transport vehicle

Abstract

The invention relates to an automatic leveling control device for an air cushion suspended transport vehicle, which controls the posture of the air cushion suspended transport vehicle. The device comprises an electric-controlled proportional pressure reducing valve (32), a remote-controlled pressure-reducing valve (31) and a height detection device (4). The height detection device (4) comprises aguide rod (11), a high-position baffle plate (17), a low-position baffle plate (18), a high-position optoelectronic switch (19) and a low-position optoelectronic switch (20) and is fixed on the air cushion vehicle, wherein the guide rod (11) is contacted with the ground; the high-position baffle plate (17) and the low-position baffle plate (18) are positioned at the same horizontal position on the left and right sides of the guide rod (11); and the high-position optoelectronic switch (19) and the low-position optoelectronic switch (20) are fixed on a pedestal (21). When the guide rod (11) glides up and down, the high-position and low-position baffle plates can baffle the high-position and low-position optoelectronic switches (19, 20). The automatic leveling control device is applicable tothe air cushion suspended vehicle.

Description

technical field [0001] The invention belongs to an air-cushion suspension vehicle, in particular to an automatic leveling control device for an air-cushion suspension vehicle. Background technique [0002] The existing air-cushion suspension transport vehicle does not have a leveling function and does not have an automatic leveling control device. When the air-cushion suspension transport vehicle encounters the situation of unbalanced load, the air cushion with heavy load will be pressed down or crushed to death, which will increase the friction force of the entire air-cushion vehicle, and even fail to float; the air cushion with small load will be raised, There may even be situations such as air cushion beating, resulting in damage to the ground or even failure of transportation. Contents of the invention [0003] The purpose of the present invention is to provide an automatic leveling control device for an air-cushion suspension vehicle, which realizes the control of th...
