(5) specific embodiment
Referring to Fig. 1, Fig. 2, a kind of method of eliminating inrun platform steel-piping impacting noise, be on sloping skid 1 or below polylith permanent magnet 4 is housed, mainly permanent magnet 4 is installed in below the sloping skid 1 in the present embodiment, and is described in greater detail.If permanent magnet 4 is installed in above the sloping skid 1, can realize by support.Permanent magnet 4 is formed concave pit with yoke 3, and concave pit touch sloping skid 1, and concave pit top is steel pipe 2, and permanent magnet 4, yoke 3 and steel pipe 2 constitute magnetic loop.Steel pipe 2 glides with initial velocity V rolling on sloping skid 1,4 pairs of steel pipes of permanent magnet 2 produce motion that attraction force acts progressively brake steel pipe 2 until being zero at sloping skid 1 afterbody, speed is zero before promptly colliding with last steel pipe 2, steel pipe is soft contact with contacting of steel pipe 2, thereby reaches the purpose of eliminating steel pipe 2 or reducing the steel pipe impact noise.To the size of the steel pipe 2 braking forces distance adjustment by 2 of permanent magnet 4 and yoke 3 and steel pipes, this distance is adjusted the range adjuster 5 that yoke 3 is fixed in sloping skid 1 below by passing yoke 3.
Referring to Fig. 2, Fig. 3, Fig. 4, a kind of device of eliminating inrun platform steel-piping impacting noise, comprise the denoising device that many groups are made up of permanent magnet 4, yoke 3, range adjuster 5, yoke 3 is L shaped, and two L shaped yokes 3 are formed concave pit with permanent magnet 4, and concave pit touch sloping skid 1, concave pit top is steel pipe 2, permanent magnet 4, yoke 3 and steel pipe 2 constitute magnetic loop, and range adjuster 5 passes yoke 3 yoke 3 is fixed in sloping skid 1 below, organizes denoising device more and is sequentially arranged in sloping skid 1 below.Permanent magnet 4, yoke 3 and steel pipe 2 constitute magnetic loop steel pipe 2 are produced attraction force acts, the downslide thereby braking steel pipe 2 rolls on sloping skid 1, make it to be reduced to zero with last steel pipe 2 speed before of clashing into mutually, be that steel pipe 2 bump moment is soft contact, thereby reach the purpose of eliminating or reducing steel pipe 2 impact noises.Yoke 3 adopts the ferromagnetic material manufacturing, plays the effect of closed magnetic circuit; Permanent magnet 4 can use permanent magnets such as ferrite, aluminium nickel cobalt, SmCo or nd-fe-b; The attractive force size that range adjuster 5 is regulated 4 pairs of steel pipes 2 of permanent magnet can constitute with bolt or hydraulic efficiency gear.Range adjuster 5 is a bolt arrangement in the present embodiment, can or screw out the purpose that screw thread reaches adjustable range by the bolt precession, and simultaneously, bolt is fixed on the whole magnetic circuit of permanent magnet 4 on the sloping skid 1, does not need to increase supporting structure again.
The structure of permanent magnet 4 can be various ways, except Fig. 3 with permanent magnet 4 about fuse the structure between two L shaped yokes 3 and with yoke 3, Fig. 4 has also provided a kind of dual permanent-magnet 4 structures, be two plots of concave pit top pits that L shaped yoke 3 is formed about permanent magnet 4 is positioned at, and arranged side by side with sloping skid 1.The magnetic force that magnetic structure shown in Figure 4 produces under the same conditions is bigger, and leakage field is almost nil, and under the condition that produces identical magnetic force, this magnetic structure can adopt the permanent magnet 4 of smaller szie, can reduce weight and cost.
Referring to Fig. 5, Fig. 6, adopt the device of the elimination inrun platform steel-piping impacting noise of two permanent magnet 4 structures, on yoke 3 top pits, the removable cover plate of being made by high permeability material 7 is housed, this cover plate 7 is as magnetic shield panel, and in the time of in working order, cover plate 7 is removed; When off working state, cover plate 7 covers, to play magnetic screening action.
