Abstract
The utility model discloses a coal mine conveyor brake device. A magnetic pole is installed in an inner cavity of a bracket rotating shaft, the bracket rotating shaft is installed on a ferromagnetic end cover through two rotating bearings, the ferromagnetic end cover and a magnetic pole machine body are combined to form an explosion-proof machine body, a magnet wire outlet box is installed on the magnetic pole machine body, and an end cover bracket is installed on the ferromagnetic end cover. A magnetic pole coil is installed on the end cover bracket, the magnet wire outlet box is connected to the magnetic pole coil, and outlet wires of the magnet wire outlet box are supplied by a wire case.
Description
Technical field
The utility model relates to a kind of conveyer braking device, and particularly a kind of colliery conveyer braking device belongs to the 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 consists of, stator is provided with some to magnetic pole, excitation coil is housed on the 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 defectives of link.
Summary of the invention
The purpose of this utility model is: provide a kind of radiating condition good, have 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 defects of existing colliery conveyer braking device.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of colliery conveyer braking device, it is by the carriage rotating shaft, magnetic pole, pole coil, the magnetic pole body, end cover bracket, ferromagnetic end cap, swivel bearing, the magnet outlet box, wiring duct box forms, described brake equipment is equipped with a magnetic pole in the inner chamber of carriage rotating shaft, the carriage rotating shaft by two swivel bearings be installed in ferromagnetic end cap above, ferromagnetic end cap and magnetic pole body are merged into explosion-proof body, at the magnetic pole body one magnet outlet box is installed, at ferromagnetic end cap one end cover bracket is installed, one pole coil is installed on the end cover bracket, be connected with the magnet outlet box on the pole coil, the outlet of magnet outlet box is supplied with by wiring duct box.
The beneficial effects of the utility model: because the utility model has adopted such scheme, during work, conveyer is braked device serial connection between motor and reductor, when electric machine rotation, brake equipment is synchronous rotary with it, after passing to direct current (DC) in the coil of the conveyer braking device of left-hand tools, directional magnetic field has been given birth in the sell of one's property, magnetic force passes through magnetic pole, stimulate body namely to form the loop, circumferencial direction along magnetic pole alternately produces eddy current like this, this eddy current again with magnetic field interaction, just produce torque, the direction of this torque is opposite with the magnetic pole hand of rotation, thereby force rotatable parts to slow down, and play brake action, reached the purpose of this utility model, the utlity model has radiating condition good, has 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 defective.
