Abstract
The utility model provides a simple, convenient and precise hoop stress online detection device of a horomill barrel body. The detection device comprises an induction detector, a counting coder, a microcomputer system and a cable, wherein the induction detector is fixed on an adjustment bracket by a bolt; the counting coder is fixed on the induction detector by a fastening screw and matched and connected with the microcomputer system respectively through the cable, sharing one direct current power supply; and the adjustment bracket is adjusted to align the induction detector with a meshing surface of a gear. A rack wheel is sheathed on the outer wall of the barrel body and meshed with a pinion that is connected with a transmission device. When the radial offset generated on the meshing surface of the rack wheel and the pinion exceeds 0.5mm, the induction detector gives out an electric pulse signal through the cable to the microcomputer system, the microcomputer system alarms automatically and analyzes and studies which causes the change of hoop stress of the barrel body, the false throw of large materials or damage from other mechanical factors according to the digital signal of the counting coder, thus being capable of taking measures in time to avoid crack of the barrel body.
Description
Technical field
The utility model relates to a kind of pick-up unit, is specially adapted to a kind of circumferential stress online detection device of horizontal roll grinding cylinder.
Background technology
The roller mill that crouches is a kind of milling equipment that utilizes the extrusion principle comminuting matter, mainly by the grinding of the realization of the pressure between roller and cylindrical shell to material.Horizontal roll grinding cylinder drives the material high speed rotating under the situation of critical rotary speed, a roller that is lying in the cylindrical shell is exerted pressure to cylindrical shell continuously, friction makes roller run up with cylindrical shell, material between cylindrical shell and the roller is pulverized under the exerting pressure of roller, sometimes because the destruction that the miscarrying of bulk materials is gone into various mechanical factors can cause the inhomogeneous of cylindrical shell circumference stress, the circumference stress inequality will cause cylindrical shell to crack even rupture, and influence is produced.At present, existing roller for sleeping in grinds also not have and overcomes this difficult pick-up unit.
The utility model content
Technical problem to be solved in the utility model is: a kind of simple, convenient, accurate circumferential stress online detection device of horizontal roll grinding cylinder is provided.
The technical scheme in the invention for solving the technical problem is: comprise inductive probe, counting encoder, microsystem and cable.Inductive probe is regulated on the support by being bolted to, counting encoder is fixed on the inductive probe with holding screw, the shared direct supply of inductive probe and counting encoder, connect by cable and microsystem respectively, adjust and regulate support, make inductive probe concordant with large and small gearing mesh face.Gear wheel is enclosed within on the cylinder body outer wall, and with pinion, pinion wheel and gearing link.
During work, gearing drives pinion rotation, and the gear wheel that is engaged with drives cylindrical shell and rotates thereupon.Go into or the destruction of various mechanical factors when causing that the cylindrical shell circumference stress is inhomogeneous when the miscarrying of bulk materials, the gear wheel that is enclosed within on the cylinder body outer wall can produce big radial deflection, and large and small gearing mesh face also produces bigger radial deflection thereupon.When the radial deflection amount of large and small gearing mesh face generation surpassed 0.5mm, inductive probe sent an electric impulse signal by cable to microsystem, and microsystem can be reported to the police automatically, and the staff should cut off roller mill power supply for sleeping at once, and is out of service.
Microsystem is transferred to the counting encoder that connects with it with electric impulse signal again with waveform simultaneously, counting encoder is converted to discernible digital signal with electric impulse signal, for staff's analysis and research, be that the miscarrying of bulk materials is gone into or the destruction of other mechanical factor has caused the change of cylindrical shell circumference stress, thereby can in time take measures, in order to avoid cylindrical shell cracks because of circumference stress is excessive even ruptures.
The beneficial effects of the utility model are: in time grasp the circumference stress situation of change of cylindrical shell, and the protection cylindrical shell of taking measures on customs clearance is not damaged the serviceable life of prolongation roller mill for sleeping in.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure: 1 is that cylindrical shell, 2 is that counting encoder, 3 is that bolt, 4 is that inductive probe, 5 is that holding screw, 6 is that adjusting support, 7 is that cable, 8 is that microsystem, 9 is that gearing, 10 is that pinion wheel, 11 is a gear wheel.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model comprises: inductive probe 4, counting encoder 2, microsystem 8 and cable 7.Inductive probe 4 is fixed on by bolt 3 and regulates on the support 6, counting encoder 2 usefulness holding screws 5 are fixed on the inductive probe 2, inductive probe 2 and counting encoder 4 shared direct supplys, connect by cable 7 and microsystem 8 respectively, adjust and regulate support 6, make inductive probe 4 concordant with large and small gear 11,10 fields of conjugate action.Gear wheel 11 is enclosed within on cylindrical shell 1 outer wall, and with pinion wheel 10 engagements, pinion wheel 10 connects with gearing 9.
During work, gearing 9 drives pinion wheel 10 and rotates, and the gear wheel 11 that is engaged with drives cylindrical shell 1 and rotates thereupon.Go into or the destruction of various mechanical factors when causing that cylindrical shell 1 circumference stress is inhomogeneous when the miscarrying of bulk materials, the gear wheel 11 that is enclosed within on cylindrical shell 1 outer wall can produce big radial deflection, and large and small gear 11,10 fields of conjugate action also produce bigger radial deflection thereupon.When the radial deflection amount of large and small gear 11,10 fields of conjugate action generation surpasses 0.5mm, inductive probe 4 sends an electric impulse signal by cable 7 to microsystem 8, microsystem 8 can be reported to the police automatically, and the staff should cut off the roller mill power supply that crouches at once, and is out of service.Microsystem 8 is transferred to the counting encoder 2 that connects with it with electric impulse signal again with waveform simultaneously, counting encoder 2 is converted to discernible digital signal with electric impulse signal, for staff's analysis and research, be that the miscarrying of bulk materials is gone into or the destruction of other mechanical factor has caused the change of cylindrical shell 1 circumference stress, thereby can in time take measures, in order to avoid cylindrical shell 1 cracks because of circumference stress is excessive even ruptures.
