Horizontal automatic correction dynamic height variable adjusting device

Abstract

The invention relates to a height adjusting device, in particular to a horizontal automatic correction dynamic height variable adjusting device. A plurality of horizontal automatic correction dynamicheight variable adjusting devices are combined to form a height-adjustable platform capable of automatically keeping horizontal, and a horizontal temporary working platform can be built on uneven terrains. Meanwhile, when the device is applied to a chassis of a vehicle (especially a low-speed special vehicle), the height of the vehicle chassis can be adjusted at will, the trafficability of the vehicle chassis and the adaptability to a working site are greatly enhanced. A main body comprises an air cylinder, a piston, a linear bearing, a polished shaft, an electromagnetic air valve, a horizontal gyroscope, a height sensor and an electric comprehensive control module, and the structural combination relation is shown in the attached drawing. In the device, the piston is fixed at one end of the polished shaft and can freely slide in the air cylinder, the other end of the polished shaft penetrates through the linear bearing and is fixed on a chassis platform, and the upper part of the air cylinder is connected with the lower part of the linear bearing. Air intake and air exhaust of the air cylinder are controlled by the electromagnetic air valve, and the electromagnetic air valve is controlled by the electric comprehensive control module through coordination of the horizontal gyroscope and the height sensor to achieve the functions of automatic horizontal correction and dynamic height variable adjustment of the device through air intake and air exhaust control over the air cylinder.

Description

technical field [0001] The invention relates to a height adjustment device, in particular to a level automatic correction dynamic height variable adjustment device. Background technique [0002] At present, most low-speed special vehicle chassis adopts a fixed-height structure, the passability of the chassis is limited, and the adaptability of the work site is relatively poor. The driving height adjustment method uses hydraulic oil as the transmission medium, which has the advantages of high performance and stable working pressure, but the fuel tank must be carried during use, which has the disadvantages of large volume, heavy weight, high cost, complex structure, poor flexibility and single function. Insufficient series. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: to provide a horizontal automatic correction dynamic height variable adjustment device to solve the technical problems of poor chassis passability and insuf...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a horizontal automatic correction dynamic height variable adjustment device to solve the technical problems of poor chassis passability and insufficient adaptability to different road conditions caused by the non-adjustable chassis height of some low-speed special vehicles. Provide a multi-purpose work platform that can automatically realize level control, and use air instead of hydraulic oil as the transmission medium, eliminating the need for heavy auxiliary equipment such as hydraulic oil tanks necessary for the hydraulic system, and the entire system is lightweight and intelligent
