Abstract
The invention provides a braking device for a coal mine conveyer. A magnetic pole is arranged in an inner cavity of a bracket rotary shaft. The bracket rotary shaft is installed on a ferromagnetic end cover through two rotary bearings. The ferromagnetic end cover and a magnetic pole body are combined into an anti-explosion body. A magnet outlet box is mounted on the magnetic pole body. An end cover bracket is mounted on the ferromagnetic end cover. A pole coil is mounted on the end cover bracket. The pole coil is connected to the magnet outlet box. A wire box provides outgoing wires for the magnet outlet box.
Description
Technical field
The present invention relates to a kind of conveyer braking device, particularly a kind of colliery conveyer braking device, belongs to brake equipment technical field.
Background technology
Colliery conveyer braking device is the important transportation accessory of colliery conveyer, in existing colliery conveyer braking device, mainly containing stator and rotor forms, stator is provided with some to magnetic pole, excitation coil is housed on magnetic pole, and rotor is armature, and it is poor that the colliery conveyer braking device ubiquity of this structure radiating condition, and be non-flame-proof type, its complex structure, many, the bulky defects of link.
Summary of the invention
The object of the invention is to: provide a kind of radiating condition good, there is blast resistance construction, simple in structure, volume is little, safe and reliable, easy to maintenance a kind of colliery conveyer braking device, overcome the existing above-mentioned defect of existing colliery conveyer braking device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of colliery conveyer braking device, it is by bracket rotating shaft, magnetic pole, pole coil, magnetic pole body, end cover bracket, ferromagnetic end cap, swivel bearing, magnet outlet box, wiring duct box composition, described brake equipment is provided with a magnetic pole in the inner chamber of bracket rotating shaft, bracket rotating shaft by two swivel bearings be arranged on ferromagnetic end cap above, ferromagnetic end cap and magnetic pole body are merged into explosion-proof body, one magnet outlet box is installed on magnetic pole body, one end cover bracket is installed on ferromagnetic end cap, one pole coil is installed in end cover bracket, on pole coil, be connected with magnet outlet box, the outlet of magnet outlet box is supplied with by wiring duct box.
Beneficial effect of the present invention: because the present invention has adopted such scheme, when work, conveyer is braked to device serial connection between motor and reductor, in the time of electric machine rotation, brake equipment is synchronous rotary with it, in the coil of the conveyer braking device of left-hand tools, pass to after direct current (DC), directional magnetic field has been given birth in the sell of one's property, magnetic force passes through magnetic pole, stimulate body to form loop, alternately produce eddy current along the circumferencial direction of magnetic pole like this, this eddy current again with magnetic field interaction, just produce torque, the direction of this torque is contrary with magnetic pole hand of rotation, thereby force rotatable parts to slow down, play brake action, reach object of the present invention, it is good that the present invention has radiating condition, there is blast resistance construction, simple in structure, volume is little, safe and reliable, advantage easy to maintenance, it is poor that actv. has overcome the existing colliery existing radiating condition of conveyer braking device, and be non-flame-proof type, its complex structure, link is many, bulky defect.
