Description
Technical Field
The utility model belongs to the technical field of antenna testing, and particularly relates to a vehicle-mounted far-field antenna testing turntable.
Background
The vehicle-mounted antenna is a device for intercepting high-frequency electric waves transmitted by the transmitting station and transmitting the high-frequency electric waves to a receiver of a car radio, a vehicle-mounted telephone or radio navigation equipment so as to demodulate carrier waves. Because the antenna test can simulate different test environments, the vehicle body and the ground have an angle, and therefore the vehicle-mounted far-field antenna test turntable is needed due to the fact that the ground where the vehicle is parked cannot be flat and the like.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide the vehicle-mounted far-field antenna testing turntable which is simple to operate, high in precision, high in efficiency and stable.
The technical scheme for solving the technical problems is as follows: the automatic leveling device is characterized in that at least one vehicle body supporting hydraulic cylinder used for controlling the height of the carriage is arranged at the bottom of the carriage, a horizontal inclinometer is arranged on the carriage, at least one adjusting electric cylinder driving a base to do vertical reciprocating motion is arranged on the carriage, a rotary table which takes the center of the base as a circle center and makes circular motion around the circle center is arranged on the base, and an autocollimator is arranged on the upper side of the rotary table.
Furthermore, the periphery of the bottom of the carriage is respectively provided with a vehicle body supporting hydraulic cylinder, and the vehicle body supporting hydraulic cylinders are symmetrically arranged.
Furthermore, the front side of the carriage is provided with a plurality of symmetrical adjusting electric cylinders, and the rear side of the carriage is provided with a plurality of symmetrical adjusting electric cylinders.
Furthermore, the plane of the top horizontal plane of the carriage is not parallel to the plane of the ground.
Furthermore, an included angle a between a plane where a top horizontal plane of the carriage is located and a plane where the ground is located is 2-3 degrees.
The utility model adopts the unified control to adjust the extension and retraction of the electric cylinder and the vehicle body supporting hydraulic cylinder, reads the data of the horizontal inclinometer and the autocollimator, adjusts the level of the carriage and the turntable, and provides an efficient leveling means for the leveling of the vehicle-mounted large antenna testing turntable.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure, a horizontal inclinometer 1, an autocollimator 2, a rotary table 3, a base 4, an electric adjusting cylinder 5, a vehicle body supporting hydraulic cylinder 6 and a carriage 7.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1, the vehicle-mounted far-field antenna test turntable of the present embodiment is formed by connecting a horizontal inclinometer 1, an autocollimator 2, a turntable 3, a base 4, an electric adjusting cylinder 5, and a vehicle body supporting hydraulic cylinder 6.
Install automobile body support pneumatic cylinder 6 respectively around 7 bottoms in carriage, 4 automobile body support pneumatic cylinder 6 mutual symmetry sets up, and automobile body support pneumatic cylinder 6 is used for controlling 7 heights in carriage, and PLC controls 4 automobile body support pneumatic cylinders 6 flexible in a unified way, makes the wheel unsettled, and carriage 7 rises certain height. The carriage 7 is provided with a horizontal inclinometer 1, and the horizontal inclinometer 1 is used for measuring whether the carriage 7 is horizontal. 2 electronic jars 5 of regulation of mutual symmetry are installed to the front side on 7 carriages, 2 electronic jars 5 of regulation of mutual symmetry are installed to the rear side on 7 carriages, it drives base 4 and is perpendicular reciprocating motion to adjust electronic jar 5, PLC controls 4 flexible of adjusting electronic jar 5 in a unified way, install revolving stage 3 on the base 4, revolving stage 3 uses the center of base 4 as the centre of a circle and is circular motion around the centre of a circle, 3 upsides of revolving stage have autocollimator 2 through screw fastening connecting piece fixed mounting, autocollimator 2 is used for measuring whether revolving stage 3 is horizontal. The plane of the top horizontal plane of the carriage 7 is not parallel to the plane of the ground. The included angle a between the plane of the top horizontal plane of the carriage 7 and the plane of the ground is 2-3 degrees.
The operation steps of this embodiment are as follows:
(1) horizontal adjustment operation of the carriage 7: the method comprises the steps that a vehicle is parked on the ground, a control module 1 controls the vehicle body supporting hydraulic cylinder 6 to stretch out and draw back, wheels are suspended, data of a horizontal inclinometer 1 are read at the same time, the reading of the horizontal inclinometer 1 is zero, the data of the horizontal inclinometer 1 are read again in real time after the vehicle is placed for 5-8 min, and if the reading of the horizontal inclinometer 1 is zero, the adjustment of the level of a carriage 7 is completed; if the reading of the horizontal inclinometer 1 is not zero, the length of the vehicle body supporting hydraulic cylinder is adjusted again through the control module 1, so that the reading of the horizontal inclinometer 1 is zero.
(2) Horizontal adjustment operation of the turntable 3: the control module 1 controls and adjusts the lifting and shrinking of the electric cylinder 5 to enable the data of the autocollimator 2 to be zero, the autocollimator 2 is placed for 5-8 min and then the reading of the autocollimator 2 is read, and if the reading of the autocollimator 2 is zero, the turntable 3 is adjusted horizontally; if the reading of the autocollimator 2 is not zero, the control module 1 adjusts and adjusts the stretching of the electric cylinder 5 again to enable the reading of the autocollimator 2 to be zero, and at the moment, the horizontal leveling operation of the rotary table 3 is completed, so that the antenna test can be carried out.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
