Two-freedom-degree regulation self-leveling spreader and regulation method

Abstract

The invention relates to a two-freedom-degree regulation self-leveling spreader and a regulation method. In the automatic spreader, an inclination sensor judges a current level degree and a motor drives a main lifting sliding block to move in a horizontal plane, so that the posture of a lifted object is regulated. The spreader uses a wireless handheld device to control the spreader; a manual control mode and an automatic control mode are provided; and an operator can selectively use the control modes according to actual lifting conditions. When the posture regulation operation is finished, the spreader can automatically measure and calculate the weight and the position of a mass center of the lifted object and display the information and the current state information of the spreader on the handheld device. The spreader is mainly applied to the lifting operation requiring precise vertical butt joint in the process of assembling large equipment and has the advantages of avoiding repeated regulation and lifting caused by unclear mass center and dissatisfactory posture of the lifted object after the object is lifted, reducing the potential safety hazard caused by complicated operation processes and simultaneously improving the lifting operation efficiency.

Description

technical field [0001] The invention relates to a two-degree-of-freedom adjustable automatic horizontal hanger and an adjustment method, which are suitable for precise vertical docking and hoisting operations in the assembly process of large-scale equipment, and belong to the field of mechanical technology. Background technique [0002] In the general assembly process of large equipment, two large structural parts are often hoisted and vertically docked. This operation has high requirements on the posture of the hoisting structure, and the two docking surfaces must be within a certain horizontal range to ensure installation accuracy. . In the process of using traditional slings, the posture of the suspended object is adjusted by changing the rope. Usually, the position of the center of mass of the suspended object is unknown. The operator needs to use experience to judge the length of the four ropes. Finally, a change in attitude is achieved. In addition, the judgment of t...

Problems solved by technology

In addition, the judgment of the levelness of the docking surface is mainly based on visual inspection, and the judgment error is large, which often leads to repeated attitude adjustments.

This hoisting method is not only inefficient, but also increases operational risks and potential safety hazards by repeated hoisting, and requires a high level of proficiency for the operator

[0003] The existing spreader with leveling function is mainly in the form of a single beam, which uses pneumatic or hydraulic methods to achieve leveling. The structure is complex and prone to leakage problems, and it is not suitable for places that require high cleanliness. The spreader can only achieve leveling in one direction, and cannot achieve leveling of the mounting surface
