Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0016] exist Figure 1A and Figure 1B A side view and a top view, respectively, of an exemplary platform structure having a platform 110 and four legs 120 for leveling are shown in 1 、120 2 、120 3 、120 4 .

[0017] As can be seen from the figure, the four outriggers 120 1 、120 2 、120 3 、120 4 Each has a horizontal part and a vertical part, wherein the horizontal part is connected to the side of the platform 110, and the vertical part is used to support the ground. In one embodiment of the present invention, the horizontal part of the leg may be a fixed structure. Alternatively, the horizontal portion of the leg is a telescopic structure. In another a...

Abstract

The invention provides a method and a system for automatic table supporting leg leveling control, and leveling equipment with the system for automatic table supporting leg leveling control. Inclination angles formed by a target plane and two coordinate axes of a parallelogram which is formed by intersection points of supporting legs with a table plane are detected, and retracting speed of the supporting legs is controlled during leveling according to the size of the inclination angles, so that stability and accuracy of the whole leveling process can be guaranteed while quickness in leveling is guaranteed, and table leveling efficiency is greatly improved.

Description

technical field [0001] The invention relates to an automatic leveling control method for platform outriggers, a control system and leveling equipment with the control system. Background technique [0002] In the field of construction machinery today, hydraulic systems are widely used to adjust the position and angle of machinery. For construction machinery such as climbing platform vehicles that require stable support before work, hydraulic outriggers are a common choice for supporting the machine and adjusting its position. Level the underbody before the platform can be raised for operation. The outrigger leveling process is a very important link in order to enable construction machinery such as climbing platform vehicles to quickly enter and work under stable conditions. [0003] At present, when leveling a platform similar to a vehicle body chassis, there are mainly two methods for leveling the outriggers: one is manual leveling, and a person adjusts the four levels in ...
