Swaying traction system and method for platforms

Abstract

The invention discloses a swaying traction system and method for platforms. The swaying traction system comprises a truss platform arranged vertically, a derrick penetrating through the truss platform in the longitudinal direction, a guide traction system arranged on an upper platform of the truss platform, winding drum drive systems driven by an electric motor and four stable systems arranged on a lower platform of the truss platform; coordinate axes XYZ are established on the basis of the center of the derrick, and the XYZ central planes of the derrick overlap with the XYZ central planes of the truss platform in initial setting; steel wire ropes form a traction circulation system, and the upper platform is provided with the winding drum drive systems driving the steel wire ropes to synchronously move in one or two axial directions of the X axis or the Y axis of the local coordinate system XOY. By arranging the stable systems, the derrick can bear certain tension, can be operated smoothly in the swaying process and does not shake. The swaying traction system and method for the platforms have the beneficial effects that the structure is simple, the work space is large and the practical engineering application value is high.

Description

technical field [0001] The invention relates to a platform swing traction system and method, which are specifically used for the simulation test of working conditions of two degrees of freedom of rolling and pitching of construction shaft platforms, marine elevator derricks and other platforms. Background technique [0002] The construction shaft platform is an important construction equipment in shaft construction. It is not only a construction operation panel, but also an equipment installation panel. Whether it can operate safely will directly affect the quality, progress and safety of shaft construction. During the lifting process of the construction vertical well platform, it is easy to cause uneven elongation of the suspension rope due to the eccentricity of the center of mass, which will cause the platform to tilt and chuck; or the deflection of the platform during the lowering process will cause a major accident of the platform colliding with the well wall. In the ea...

Problems solved by technology

[0004] At present, the working condition simulation test platform with two degrees of freedom of lateral swing and longitudinal swing generally uses hydraulic cylinders as the drive system. However, the hydraulic drive system uses liquid as the working medium, and there will inevitably be leakage during operation. Affect the stability of the overall operation of the system; the hydraulic system has a lot of energy loss during the working process, such as friction loss, leakage loss, etc., so it is not suitable for long-distance transmission; the hydraulic system is sensitive to oil temperature changes, oil temperature changes will Affect the stability of the movement; the response of the hydraulic system is slow and the operation is not sensitive
