Chinese patent 92218059.8 discloses and has utilized electromagnet carrying steel pipe to collecting the device that abates the noise in the frame, but this device is still very complicated, and handling efficiency is low, needs increase hydraulic gear and power, transforms and invest relatively large.Chinese patent 200510025577.9 discloses a kind of low noise steel pipe collection method and device with low cost, this patent disclosure adopt the permanent magnet technology that the kinematic velocity of steel pipe is carried out damping control, can effectively reduce the noise that steel pipe clashes into mutually, but the magnetic force of this patent permanent magnet is regulated inconvenient, especially to the working condition of steel pipe specification frequent variations, comformability is poor.
The utility model content
The purpose of this utility model is to provide a kind of steel pipe electromagnetic braking denoising device, and this device can be regulated magnetic force easily, adapts to the production that changes the specification steel pipe, effectively reduces or the mutual impact noise of elimination steel pipe.
The utility model is achieved in that a kind of steel pipe electromagnetic braking denoising device, comprises electromagnet, fixed mount, excitation source, signal transducer and controller; At least one electromagnet is arranged on the sloping skid below of transmitting steel pipe, and fixed mount is L shaped structure, and the part of fixed mount vertical ground is connected with sloping skid, and electromagnet is connected the upper surface that fixed mount is parallel to ground segment; Signal transducer is arranged on the sloping skid, and signal transducer is positioned at the upstream and the contiguous electromagnet of electromagnet on the steel pipe sense of motion; Electromagnet is connected with excitation source, and excitation source is connected with controller, and controller is connected with signal transducer simultaneously.
Described electromagnet is being provided with more than one on the steel pipe length direction at least.
Described electromagnet is DC electromagnet or alternating electromagnet.
The utility model is to utilize electromagnet steel pipe to be produced the characteristic of electromagnetic force, installation electromagnet below sloping skid, magnetic loop is formed with the steel pipe that moves in the magnetic field that electromagnet produces on sloping skid, generation is to the braking force of steel pipe, the speed that steel pipe is rolled on sloping skid reduces or braking fully, steel pipe is zero or clashes into mutually with very little speed in the mutual spot speed of bump like this, reaches the purpose that reduces or eliminate the steel pipe impact noise.The size and the mode of operation of controller control exciting current adapt to the electromagnetic braking of different steel pipe specifications.
In the steel pipe's production process, judge by signal transducer whether steel pipe passes through from electromagnet.When steel pipe moved near electromagnet, signal transducer provided signal, made excitation source to the electromagnetic system power of electromagnet power supply generation to steel pipe by controller, and the kinematic velocity of steel pipe is reduced or braking fully.Electromagnet can be according to steel pipe different length or weight size, and grouping is control respectively.Electromagnet has reverse energising or logical oscillating current demagnetization ability under the combined action of control system and excitation source.The electromagnet energising can be to continue the energising mode of operation, also can be that part continues the energising mode of operation.The size of the electromagnetic system power of electromagnet is stepless adjustable by excitation source, and the noise reduction that can adapt to the different size steel pipe's production is administered.
The utlity model has following beneficial effect: apparatus structure is simple, can effectively reduce or eliminate the mutual impact noise of steel pipe, has overcome the defective of prior art, and magnetic force is easy to adjust, and the production that changes the specification steel pipe is had very strong comformability.
