Embodiment Construction

[0013] The structure of the two electromagnets is exactly the same, and they are installed symmetrically at the front and rear ends of the loading platform. The electromagnet is U-shaped, and the four electromagnet coils are respectively wound on the four U-shaped columns of the electromagnet. The number of turns and the winding direction of the coil are exactly the same. .

[0014] The parameters of the four pressure sensors are exactly the same, and they are installed symmetrically on four points, front, rear, left, and right at the bottom of the loading platform. For the installation positions, see figure 1 .

[0015] The pressure sensor can detect the pressure of the loading platform on the track, and the detection values ​​of the four pressure sensors are sent to the solenoid coil control unit, and the control unit controls the current output to the four electromagnet coils according to the detection value, and finally makes the four pressure The detection value of the s...

Abstract

The invention discloses a load transfer platform with controllable weight reduction by electromagnetic force, which is used for high-precision displacement of large heavy objects. It has a track (3) and a U-shaped load-carrying platform (1) whose upper part is placed on the track (3) and can slide along its surface; a magnetic force generating mechanism is arranged between the lower part of the track (3) and the lower part of the U-shaped load-bearing platform. The generating mechanism has two electromagnets symmetrically distributed at the front and rear ends of the loading platform. The four electromagnet coils are respectively wound on the four U-shaped columns of the two electromagnets. The magnetic force generating mechanism generates and attracts the lower part of the U-shaped loading platform upwards. suitable suction. The load transfer platform of the invention exerts very little pressure on the track, which makes the movement of heavy objects easier to realize. The current of the electromagnet coil is controlled by the electromagnet coil control unit, so that the pressure of the load-carrying platform on the track is small and evenly distributed on the track, ensuring that the object will not swing up and down, left and right, and nod from front to back, left and right, so as to ensure The high-precision movement of the required moving object in the direction of the track is realized.

Description

technical field [0001] The invention relates to a movable platform, in particular to a controllable weight reduction scheme for large and heavy objects moving with high precision. Background technique [0002] At present, when large and heavy objects are moved, large-scale handling equipment is often required. If fine processing or other high-precision processing is required for such objects, higher precision requirements are required for their handling or movement. However, due to its bulky size, especially its high quality, traditional large-scale handling equipment is difficult to operate and it is difficult to meet the requirements of high-precision movement. If the electromagnetic force is used to reduce the weight of the object, it will become easier to move the weight-reduced object with high precision. Contents of the invention [0003] The purpose of the present invention is to provide a controllable weight reduction scheme using electromagnetic force to realize ...
