Description
Technical Field
The utility model relates to a fire prevention rolling door machine technical field especially relates to a brake connection structure of heavy fire prevention rolling door machine.
Background
The fire-proof rolling door machine is used on a fire-proof rolling door in a fire-fighting place, and is provided with a brake device for braking the ascending and descending of the fire-proof rolling door. The brake device consists of an electromagnet, a brake block and a brake disc, and the brake disc is fixed on the motor rotating shaft. When the brake is released, the electromagnet is electrified to work to attract the brake block, the brake block is separated from the brake disc, and the motor rotating shaft rotates.
When the fire-proof rolling door is stopped in ascending and descending, the weight of the whole door body is intensively reflected on the braking force of the braking device, once the braking device goes wrong, the whole door body can be broken down and even hurt people and objects, so the braking effect is the decisive effect of the parts such as the brake disc, and the braking effect of the braking device is directly related to the safety of the whole fire-proof rolling door.
When the brake disc of the existing heavy fire-proof rolling door machine is in friction braking with the brake block, abrasive dust is often generated, the abrasive dust cannot be discharged to the outside of the fire-proof rolling door machine, the braking effect is influenced in the braking device, and a great potential safety hazard is buried.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art's is not enough, provides a brake connection structure of heavy fire prevention rolling door machine.
The utility model discloses a realize through following technical scheme: a brake connecting structure of a heavy fire-proof door roller comprises a motor fixing seat, a tubular connecting part and a fixing ring, wherein the motor fixing seat, the tubular connecting part and the fixing ring are fixedly connected in sequence from left to right; the motor fixing seat is a disc-shaped fixing seat, the outer diameter of the disc-shaped fixing seat is slightly larger than that of the connecting part, a flange is formed on the outer wall of the connecting part, bolt holes are formed in the circumference of the flange, and a motor rotating shaft hole is formed in the center of the motor fixing seat; the cylindrical connecting part is hollow, a through groove is formed in the cylindrical wall right below the cylindrical connecting part, so that the inner part and the outer part of the cylindrical wall right below the cylindrical connecting part are communicated, sliding grooves and a collecting box are formed in the left side and the right side below the through groove, and the collecting box can slide on the sliding grooves; the fixing ring is arranged on the outer wall of the rightmost side of the connecting part, and fixing holes for fixing with a brake device of the fireproof door rolling machine are formed in the circumference of the fixing ring.
The utility model has the advantages that: in the brake equipment course of operation of fire prevention rolling door machine, there is the abrasive dust production, and the abrasive dust that produces can drop in the collection box of connecting portion below, and over a period of time, can take out and collect box clearance abrasive dust, reduce the abrasive dust and be detained at the inside potential safety hazard that causes of brake equipment of fire prevention rolling door machine, simple structure.
