Embodiment Construction
[0030] refer to Figure 1 to Figure 6 , the method of the present invention uses the side cantilever between the azimuth rotation axis and the pitch rotation axis to amplify the moment generated by the load platform and the load gravity by the side cantilever to perform accurate and stable leveling of the load platform. The length of the side cantilever of the method of the present invention is 50mm to 2000mm, and the length of the side cantilever of the embodiment is 350mm.
[0031] The device of the present invention consists of a lifting mast 1, an azimuth rotation axis 2, a side cantilever 3, a pitch rotation axis 4, a vertical arm 5, and a load platform 6, as Figure 1 to Figure 6 shown.
[0032] The method of the present invention comprises steps:
[0033] ① Install the azimuth rotation axis 2 on the lifting mast 1, and the azimuth rotation axis 2 can rotate 360° around the lifting mast 1; one end of the side cantilever 3 is installed on the azimuth rotation axis 2, an...

The invention discloses a load levelling method of an elevator mast, and relates to the levelling technology of elevating equipment platforms in the fields of radars, photoelectric sensors, microwave communication and the like. In the load levelling method, a side cantilever is adjusted to an angle which is consistent with an inclined direction of the elevator mast by adjusting an azimuth rotating shaft on the elevator mast, and then a pitching rotating shaft is adjusted, so that a vertical arm is vertical to the ground; and a load platform is mechanically vertical to the vertical arm, so that the load platform is adjusted to a horizontal or specified angle of elevation under the condition that the elevator mast inclines. The load levelling method has the advantages that a structure of the device is simple and easy to implement, the simple mechanism is adopted to realize the high levelling precision, a mast system adopting the mechanism is strong in stability and easy to lock, the requirement of mast strength can be reduced greatly under the condition of the same angle precision and the like. The load levelling method can be widely used for the levelling installation of fixed load elevating platforms, vehicle-mounted load elevating platforms and the like.
Description
technical field [0001] The invention relates to a load leveling method of a lifting mast in the fields of radar, photoelectric sensor, microwave communication and the like. Special equipment platform leveling system suitable for lifting work. The leveling system can be a radio frequency antenna of a radar system, or a photoelectric sensor, or a transceiver antenna of a microwave communication system, etc., and a stable leveling platform device that needs to provide lifting work. Background technique [0002] Liftable working equipment includes a lifting mast (or mechanism), and the special requirement is that it can work normally only when its loading platform is close to the level. When the carrier is not parked on a level ground, the equipment working platform must be leveled. [0003] The current leveling methods used for equipment load platforms include jack leveling, stable platform leveling, and azimuth pitch leveling. However, the above-mentioned existing load plat...
