Table-board supporting device for overlarge spliced platform

Abstract

The invention discloses a platform support device for a super-large splicing platform. Each sub-platform of the splicing platform is provided with 6 support feet with adjustable support heights, and the 6 support feet are divided into active support feet and auxiliary support feet. Two sets of supports, the support feet in each group of supports are arranged in an equilateral triangle, and the two triangles are mirrored to form a square with the isosceles line as the symmetrical line; the active support feet maintain and actively adjust the level of the sub-platform, and the auxiliary support feet assist in supporting The weight of the sub-platform, active support feet and auxiliary support feet are all closed-loop control. The closed-loop fine-tuning active support foot of the present invention can quickly adjust the level of the platform table, and the force-sensing auxiliary support foot can share the gravity of the sub-platform, and can effectively overcome the deformation of the sub-platform table due to its own weight and load changes. The device adopts closed-loop control with a high degree of automation, and can quickly adjust the level of the sub-platform table, thereby ensuring the horizontal accuracy requirements of the splicing platform.

Description

technical field [0001] The invention relates to a platform supporting device for a super large splicing platform, in particular to a supporting foot structure of a sub-platform. Background technique [0002] In the prior art, light load platforms can generally determine a plane based on the axiom of three points, and adjust the three points of the support surface to obtain a datum plane. This type of platform has no auxiliary support feet, and it is prone to deformation when the foundation settles and the load is large deviation. For platforms with limited loads, you can use four-point or five-point leveling to obtain a reference plane. This type of plane has auxiliary support feet, but they are all manual auxiliary support feet; this type of manual auxiliary support feet loads the platform table. It is not known that when the loading force is too large, it is easy to damage the level of the platform table; if the loading force is too small, it is easy to cause empty feet, ...

AI Technical Summary

Problems solved by technology

The manual adjustment is rough and the adjustment time is long. If it is a spliced ​​super-large platform, it takes a long time to adjust the level manually through manual observation of the level meter, and the consumption of manpower and material resources is huge; The liquid has high elasticity when loaded, which is prone to errors, and the hydraulic power method is greatly affected by the ambient temperature and has poor stability; although the simple electric adjustment shortens the adjustment time and correspondingly improves the adjustment accuracy, there is no auxiliary support or without force perception

[0004] Regarding the transmission mode of the support foot, the support mechanism is equipped with a simple screw lifting mechanism, a hydraulic mechanism or a simple electric mechanism. The screw lifting mechanism is often rotated manually, and the current and accurate force distribution cannot be known scientifically and effectively. The adjustment of the mechanism is difficult, the adjustment accuracy is not high, and the adjustment time is long; the adjustment accuracy of the hydraulic mechanism is limited, and the stability after adjustment is poor; the simple electric mechanism can overcome the shortcomings of the screw lifting mechanism and the hydraulic mechanism, but it cannot form a closed-loop control. The adjustment accuracy is not high; there is no external communication interface, and the sub-platforms cannot really be spliced ​​into a super-large platform
