For antenna being protruded upward from compartment and returning in compartment, on automobile, to there is the hoistable platform of car antenna.Hoistable platform has horizontal platen, and horizontal platen is connected with drive unit, and drive unit can drive horizontal platen elevating movement.Satellite earth antenna hoistable platform requires lifting convenient, and lifting position precision is high, good stability, and anti-jitter, wind loading rating are strong.
In prior art, mostly the drive unit of horizontal platen is hydraulically powered scissor-type device.This hoistable platform is during as car antenna hoistable platform, lifting position precision be not very high, stability is bad, anti-jitter, wind loading rating are not very strong, are not suitable as the hoistable platform of antenna.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind of lifting rational in infrastructure convenient, good stability, anti-jitter, the car antenna hoistable platform that wind loading rating is strong.
The utility model is realized with the following method.
Car antenna hoistable platform has horizontal platen, horizontal platen is connected with drive unit, drive unit has first of four jiaos, rectangle at grade, second, the third and fourth four right-angular drive gearboxes, right-angular drive gearbox has horizontal power shaft and screw rod output shaft vertically upward, there is bearing pedestal screw rod output shaft upper end vertically upward, between power shaft in right-angular drive gearbox and screw rod output shaft, there is the bevel gear being meshed, four jiaos of horizontal platen have respectively the screw matching with output shaft screw rod, second and the power shaft of the 3 two right-angular drive gearbox cross transmission case and be connected with motor, second and the 3 two right-angular drive gearbox have respectively horizontal output shaft, horizontal output shaft in right-angular drive gearbox is meshed with above-mentioned bevel gear,
Two horizontal output shafts are respectively first and the power shaft of the 4 two right-angular drive gearbox.
The utility model can be arranged on the automobile with hexahedron shelter, and the top board of shelter has skylight.
When installation, four right-angular drive gearboxes of the present utility model are arranged on the horizonal base plate of automobile shelter, the bearing pedestal of screw rod output shaft upper end is vertically upward arranged on the top board of automobile shelter, elevating lever or the satellite earth antenna with whip antenna can be installed on horizontal platen.
When use, with the horizontal power shaft rotation of motor driving second and the 3 two right-angular drive gearbox, and driven first and the power shaft of the 4 two right-angular drive gearbox rotate, and then drive four right-angular drive gearboxes screw rod output shaft synchronous vertically upward to rotate, four right-angular drive gearboxes screw rod output shaft synchronous vertically upward rotates and can drive horizontal platen elevating movement, and horizontal platen elevating movement can drive antenna lifting.After horizontal platen rises, the top that antenna can stretch out shelter by the skylight on the shelter top board of opening, for collecting electromagnetic wave signal, after horizontal platen declines, antenna can enter in shelter, and the skylight of closing on shelter top board is convenient to mobile.
The utility model motor is power, with right-angular drive gearbox be transmission device, the direct drive unit that is horizontal platen with screw rod, nut, rational in infrastructure, lifting is convenient, good stability, anti-jitter, wind loading rating are strong, are suitable for the hoistable platform as antenna.
Below in conjunction with accompanying drawing, the utility model is further described.
