Abstract
The utility model discloses a flame-proof type cylinder linear electric motor for mechanical equipment making rectilinear movement in operationally dangerous environments, such as an underground coal or coal mine alike, chiefly comprising a shell, a sliding bearing, a secondary stage device, a core, a coil, a flame-proof connection box, a dust guard ring, a terminal, etc. Because bodies can mutually be joint and made according to the requirement of the technology of a flame-proof joining surface, terminals are all assembled in an identical flame-proof box. The electric motor has the performances of explosion suppression, dust resistance, good sealing performance and humidity resistance and reasonable structure, repair and use.
Description
The utility model relates to a kind of flame-proof mine cylindrical linear motor, and there is the drive unit of moving linearly plant equipment in the explosion risk environment under the suitable coals mine or similar colliery.
The application of universality cylindrical linear motor has been used for behaviour's vehicle device and other plant equipment on coal mine well port ground, makes drive unit in car arrester, goat, emergency exit, gate and the automatically-controlled door isoline movable machinery equipment for well head behaviour vehicle device.But in prior art, the plain edition cylindrical linear motor is not suitable under coal mine or has in the explosion risk environment using, and makes coal mine well port, plant equipment that the shaft bottom structure is identical can not get unified supporting and standardization.
The purpose of this utility model provides a kind of flame-proof type cylindrical linear motor that is applicable under the coal mine or the plant equipment of moving linearly in the explosion risk environment is arranged.
Structure of the present utility model is by forming with the lower part: shell, sliding bearing, secondary, iron core, winding, terminal block, terminals, lead-in wire horn mouth, winding connection chamber cover plate, winding connection chamber, explosion-proof connection box, explosion-proof chamber, dust ring and flameproof joint.
Flameproof joint has three places, between (1) shell and the winding connection chamber cover plate; (2) between shell and the sliding bearing; (3) between the secondary and sliding bearing.
Be fixed with the hollow rubber dust ring with secondary surperficial touching position respectively at the two ends of shell.For explosion-proof, all group of terminals are contained in the same explosion-proof connection box.
There is the explosion-proof chamber of a constant volume inside of explosion-proof connection box, is provided with three power-line terminals in the chamber, a ground connection screw, and cable is drawn by horn mouth.
Fig. 1 is a flame-proof type cylindrical linear motor structure chart
Fig. 2 is the profile of flame-proof type cylindrical linear motor explosion-proof connection box
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is made up of shell 1, sliding bearing 2, explosion-proof connection box 3, secondary 4, iron core 5, winding 6, dust ring 7, flameproof joint 8,9,10, terminal block 11, explosion-proof chamber 12, terminals 13, lead-in wire horn mouth 14, winding connection chamber cover plate 15, winding connection chamber 16.
Be provided with winding connection chamber 16 in its shell 1, the head of each coil, tail connect into motor windings 6 by the wiring requirement in winding connection chamber 16, and the three-phase leading-out terminal of winding 6 inserts on the terminals 13 of explosion-proof connection box 3 internal wiring plates 11.The outside Plastic-sheathed Cable of introducing is to be connected with terminals 13 in the explosion-proof connection box 13 by horn mouth 14, and cable is sealed in horn mouth 14, has guaranteed that cable introducing place is prevented dust, flame proof and cable can pull-offs.
Sliding bearing 2 be support secondary 4, secondary 4 with the certain interval that is combined with of sliding bearing 2, can make the two linear reciprocating motion.In order to prevent that secondary 4 bring coal dust and moisture into motor internal in reciprocating motion, the end of two sliding bearings is provided with hollow rubber dust ring 7.1 on explosion-proof connection box 3 and shell are connected by flameproof joint 8.
The inside of explosion-proof connection box 3, the explosion-proof chamber 12 that one constant volume is arranged, be provided with three power-line terminals in the chamber, a ground connection screw, the electric clearance between binding post is not less than 8mm, and creepage distance is not less than 18mm, cable is drawn by horn mouth 14, the flameproof joint 8 that winding connection chamber cover plate 15 and shell are 1, sliding bearing 2 and secondary flame proof composition surface 10, sliding bearing 2 and 1 flame proof composition surface 9 of shell, its gap is all less than 0.40mm, and surface roughness all is not less than 6.3.
When feeding three-phase alternating current, motor windings 6 produces the space travelling-magnetic-field of a translation.According to electromagnetic induction principle, secondary 4 surfaces produce induced potential, carry out rectilinear motion under the effect in magnetic field.
