Problems solved by technology
If the wear of supporting wheel and running wheel exceeds a certain range, it will affect the normal operation of the mold, make the cement pipe mold bend and deform, and seriously affect the quality of the product
The uneven wear of the supporting wheel and the running wheel will also cause the mold to jump, which will not only affect the quality of the cement product, but also accelerate the wear
The axial movement of the mold will also increase the wear of the rims of the supporting wheel and the running wheel, increase the load on the equipment, and may cause serious accidents such as speeding
Moreover, the energy consumption is large, the operating cost is high; the noise is large, and the working environment is poor

The invention discloses a permanent magnet suspension support for a centrifugal cement pipe making machine. The permanent magnet suspension support comprises a permanent magnet ring and a permanent magnet bracket, the permanent magnet ring comprises suspension permanent magnets and yoke iron, the yoke iron is in a circular ring shape, the suspension permanent magnets are evenly distributed on the outer circumferential face of the yoke iron, and the magnetic field direction of the suspension permanent magnets is in the radial direction; the permanent magnet bracket comprises fixed permanent magnets and a supporting seat, the fixed permanent magnets are uniformly distributed on the upper surface of the supporting seat, and the magnetic field direction of the fixed permanent magnets is perpendicular to the tangent line of the plane; and the permanent magnet ring is located right above the permanent magnet bracket, the suspension permanent magnets are opposite to the fixed permanent magnets, and the opposite magnetic pole faces have the same polarity, so that repulsive force is generated, and the permanent magnet ring is suspended above the permanent magnet bracket. The permanent magnet suspension support is simple in structure, eliminates abrasion of a die during operation, reduces noise generated by friction, reduces friction force, reduces energy consumption, and is suitable for application and popularization.
Description
technical field [0001] The invention relates to the field of permanent magnetic suspension, in particular to a permanent magnetic suspension support for a centrifugal cement pipe making machine. Background technique [0002] The centrifugal cement pipe making machine is the main supporting equipment for the production of reinforced concrete culvert pipes and various annular concrete product components. The cement pipe mold is supported by supporting wheels and running wheels, but during use, the supporting wheels and running wheels are very easy to wear. If the wear of supporting roller and running wheel exceeds a certain range, it will affect the normal operation of the mold, make the cement pipe mold bend and deform, and seriously affect the quality of the product. The uneven wear of the supporting wheel and the running wheel will also cause the mold to jump, which will not only affect the quality of the cement product, but also accelerate the wear and tear. The axial mov...
