Abstract
The utility model relates to an automatic braking anti-explosive motor for a lift, belonging to the technique of motor manufacture. The utility model is characterized in that the structure of tapered rotor is adopted, a motor and a brake are integrally combined, and an explosion-proof casing is used; a manual brake releasing device is arranged on the rear end cover of the motor, and the braking state of the motor can be manually relieved. The utility model can be used as a driving motor for anti-explosive elevators, lifters, cranes, etc.
Description
The utility model is a kind of motor that is used for the explosion-proof type elevator traction machine, belongs to motor manufacturing technology.
The existing self-retention fire-proof motor product of China is the supporting conical rotor machine of our factory's explosion-proof type electric block etc. as lifting equipment factory, Fujin, Heilungkiang at present, and its brake and motor are integral structure, and explosion-proof performance is better.But it does not possess the function of " manually release brake ", is unsuitable for using on elevator traction machine.
The purpose of this utility model is to provide a kind of self-retention motor that uses on the explosion-proof type elevator that is applicable to, to simplify the structure of explosion-proof type elevator traction machine, improves the anti-explosion safety performance.
Elevator is seen accompanying drawing with the structure of self-retention fire-proof motor.Design feature is that the stator and the rotor taper direction of the cone rotor fire-proof motor of lifting equipment factory, Fujin development are turned 180 °, sets up manual brake release on rear end cap.Because the interior circle of motor stator (4) and the cylindrical of rotor (5) are taper shape, stator during energising (4) also produces by the axial magnetic pulling force of big end to small end rotor (5) except that producing rotating magnetic field, the thrust that forces rotor (5) to overcome tripping spring (2) is done axial displacement, brake disc (6) and braking sleeve (7) are broken away from, and rotor is starting operation just; When motor cuts off the power supply, because stator (4) disappears to the magnetic pull of rotor (5), rotor (5) is axially moved to big end by small end under the promotion of tripping spring (2), make brake disc (6) and braking sleeve (7) pressing, frictional force by the two stops rotor (5) to rotate, i.e. be in on-position during motor outage.
For adapting to the requirement of in case of emergency answering " manually release brake " among the GB7588--87 " elevator manufacturing and installation safety standard " about traction machine, the utility model has designed the brake manual brake release, is made up of declutching top (8) of being located at that motor rear end covers and back-moving spring (9) etc.Usually declutch top (8) under the effect of back-moving spring (9), the 3mm gap is arranged with the rear end face of motor shaft (1), do not influence the normal operation and the braking of motor; When motor when off-position needs brake off, an available lever facility equipressure compel to declutch top (8) withstand motor shaft (1) and move 1.5～2mm brake disc (6) and braking sleeve (7) are broken away from.
Motor housing (3) is the flame-proof type structure, and it might produce the part of spark, electric arc and high temperature to motor stator, rotor and brake etc. and come with imflammable gas on every side is isolated, realizes the flame proof requirement.
Production now or the explosion-proof lift that uses, its traction machine is made up of fire-proof motor, anti-explosion is electromagnetic brake and reductor etc., anti-explosion is electromagnetic brake complex structure, and friction spark between brake shoe and braked wheel and the difficult control of instantaneous temperature.The utility model is because brake places in the explosion-proof shell of motor, and explosion-proof performance is reliable, and can replace motor, electromagnetic brake and the braked wheel etc. that branch is arranged in the explosion-proof lift traction machine with this, has simplified the traction machine structure, reduces production costs.
When implementing the utility model, the structure of rotor, stator and electromagnetic parameter adopt the data of China approved product CD1 type conical rotor machine.Explosion-resistant enclosure adopts HT20-40 to make.Declutch top and the axis hole etc. of forward and backward end cap and support connection place, motor output shaft and axis hole, rear end cap are flameproof joint, manufacture by the regulation of GB3836.2-83.
The utility model can be used as the drive motors of explosion-proof type elevator, is applicable to that also explosion-proof type elevator, explosion-proof type crane etc. have the explosion-proof type equipment of brake request.
Claims (3)
1, a kind of elevator self-retention fire-proof motor, it is characterized in that the cone rotor structure, the flame-proof type shell, motor makes brake disc (6) and braking sleeve (7) pressing by the thrust of tripping spring (2) during outage, with the frictional force prevention motor rotation of the two, oppresses tripping spring (2) by the stator (4) and the electromagnet pull of rotor (5) during energising, brake disc (6) and braking sleeve (7) are broken away from, motor is starting operation just, is provided with manual brake release on the motor, the on-position in the time of removing outage.
2, elevator according to claim 1 self-retention fire-proof motor, the manual brake release that it is characterized in that brake is to cover at motor rear end one declutch top (8) have been installed, oppress declutch top (8) rotor (4) is axially moved, brake just unclamps.
3, elevator according to claim 2 self-retention fire-proof motor, it is characterized in that having installed on the brake manual brake release top back-moving spring (9), when not needing manually to declutch, the rear end face of declutch top (8) and motor shaft (1) keeps the gap, does not influence motor and runs well.
