Rotation lifting leveling mechanism

Abstract

The invention provides a rotation lifting leveling mechanism and belongs to the field of leveling machines. The rotation lifting leveling mechanism comprises a leveling installation base, a stepping motor, a rotation bearing, a rotation lifting connection part, a lower lifting mechanism frame, a lifting triangular arm, a lifting oil cylinder, a triangular arm support, a pull rod, an oil cylinder pull rod support, an upper lifting frame, an upper turnover support and a lower turnover support. Main motion of the rotation lifting leveling mechanism is rotation motion and turnover motion, rotation motion is achieved through the rotation bearing, and turnover motion is achieved through a lifting mechanism. Power for rotation motion is provided by the stepping motor, power for turnover motion is provided by the lifting oil cylinder, rotation motion and turnover motion have access to an automatic control system, and accordingly automatic leveling can be achieved. The rotation lifting leveling mechanism can achieve direct leveling at a large angle and meets the requirement of leveling operation under mountains, abrupt slopes and other complex terrain.

Description

technical field [0001] The invention relates to the field of leveling machinery, in particular to a rotary lifting leveling mechanism. Background technique [0002] In mechanical equipment that needs to provide a level working platform, a leveling mechanism is essential. A good leveling effect is a prerequisite for the smooth operation of the working mechanism. For example, the base of the vehicle radar and the working platform of the lifting mechanism all require good leveling functions. [0003] However, the existing leveling methods, whether it is manual leveling or automatic leveling, use outriggers as the main structure of the leveling, and the working platform can achieve the required leveling effect through the expansion and contraction of the four outriggers, which are collectively referred to here as Outrigger leveling method. In "Vehicle Radar Electromechanical Automatic Leveling Control System" (Journal of Huazhong University of Science and Technology, 2004, 32(...

AI Technical Summary

Problems solved by technology

[0005] (1) The method of outrigger leveling. During the leveling process, the expansion and contraction of each outrigger will have an impact on other outriggers. During leveling, repeated leveling is required to achieve the final leveling accuracy requirements in a gradually approaching manner. The leveling process Complicated, long leveling time and low efficiency

[0006] (2) It is difficult to avoid the phenomenon of empty legs when leveling the outriggers, which is a hidden danger in the leveling process. In addition to the leveling operation, the general leveling process also needs to add an operation to eliminate the empty legs, which adds a lot to the leveling process. necessary burden

[0007] (3) When the outriggers are leveled, the outriggers will be displaced during the leveling process, which increases the extra load in the leveling process and also adds unstable factors to the leveling process

The load on the outriggers also becomes complicated

[0008] (4) When the outrigger is leveled, the angle between the outrigger and the equipment changes, which makes the connection between the car body and the outrigger prone to deformation

[0009] (5) The leveling of the general outriggers is not only the leveling of the working platform, but the leveling of the entire equipment, which increases the leveling load and increases the bending deformation of the main bracket

[0010] (6) The range of outrigger leveling is limited. Due to the reasons (3) and (4), outrigger leveling is generally carried out within a small angle range

In the case of large angles, the equipment can only be moved to an environment that satisfies the leveling angle range of the outriggers for leveling, which greatly limits the working range of the leveling equipment
