Magnet translation driving device and using method thereof

Abstract

The invention relates to a magnet translation driving device and a using method thereof. The device comprises a bottom plate, a hoisting mechanism and a translation mechanism, wherein a magnet is placed on the top face of the bottom plate. The hoisting mechanism comprises more than three hoisting screw rods which are distributed around the magnet, the top of each hoisting screw rod is in a square shape or a hexagon shape, and the middle part of each hoisting screw rod is connected to the bottom plate through a square nut or a hexagonal nut. The translation mechanism comprises two motors which are respectively and symmetrically connected to one end of the bottom plate through a motor support. The output ends of the two motors are respectively connected with a speed reducer, the output ends of the two speed reducers are respectively connected with a driving chain wheel, and the two driving chain wheels are respectively connected with a driven chain wheel through a chain. The two driven chain wheels are respectively and coaxially connected with a driving wheel, the two driving wheels are respectively supported on a driving support in a rotating mode, and the two driving supports are respectively and fixedly connected to the bottom face of the bottom plate. The bottom face of the bottom plate between the two chains is fixedly connected with a supporting plate, the supporting plate is connected with a steering supporting frame in a rotating mode, and the steering supporting frame is connected with a steering wheel.

Description

technical field [0001] The invention relates to a magnetic resonance device and its use method, in particular to a magnet translation drive device and its use method. Background technique [0002] In the permanent magnetic resonance system, the magnet is used as the main part, which is mainly composed of carbon steel and magnetic materials. Generally speaking, the volume of the magnet is large, and its mass is also large, basically between 8 and 25 tons. Since the magnet has a strong magnetic field and a heavy mass, there are many difficulties in moving or handling the magnet. [0003] Conventional magnet movement is basically carried out in the following way: first use a jack to lift the magnet from the bottom, then lay a number of small handling tanks under the magnet, then withdraw the jack, then use a steel cable to pull the magnet, use electric hoist, hoist Or other power mechanism pulls the steel cable to make it advance, and after the magnet is in place, jack it up ...

Problems solved by technology

The above-mentioned method has the following disadvantages: 1. Time-consuming and labor-intensive, the transportation speed of this method is slow, and the general transportation needs to be lifted and disassembled repeatedly to carry the tank; Most of the heavy tools are made of carbon steel, which are easily attracted to magnets with strong magnetic fields, which may cause personal injury or property damage; 3. Due to the complicated transportation process, professional transportation personnel are required to implement

Compared with the above-mentioned moving methods, the air cushion handling device is flexible and convenient, and has a simple structure, but this transportation method is expensive and has special requirements for the ground: due to the small ground clearance, the ground is required to be flat and seamless, and the macroscopic undulations and microscopic roughness of the ground are different. It is not allowed to exceed the specified value, otherwise the energy consumption will increase due to air leakage, and even the heavy objects cannot be supported. After the air cushion lifts the heavy objects, the ground will slide automatically when the ground slope is slightly larger

Therefore, this method is not suitable for widespread use
