Abstract
The utility model discloses an explosion-proof electromagnetic brake. The explosion-proof electromagnetic brake comprises a braking shaft, a braking device, a brake shell and a junction box. The explosion-proof electromagnetic brake is characterized in that the brake shell, an end cover of the brake shell, a junction box shell, and an end cover of the junction box shell are explosion-proof, a seal ring is installed between the brake shell and the end cover of the brake shell, a second seal ring is installed between the junction box shell and the end cover of the junction box shell, and the joint surface between the brake shell and a bearing end cover, the joint surface between the braking shaft and a copper sleeve, the joint surface between the junction box shell and the end cover of the junction box, and the joint surface between the junction box shell and the brake shell all meet joint surface requirements of gas explosion-proof dIICT4 and dust explosion-proof DIPA21TAT4. Compared with the prior art, the explosion-proof electromagnetic brake has the advantages of achieving the gas explosion-proof dIICT4 and the dust explosion-proof DIPA21TAT4.
Description
Technical field:
The utility model relates to a kind of break, particularly a kind of anti-explosion is electromagnetic break.
Background technique:
Break in elevating mechanism has hydraulic braking, mechanical braking and electromagnetic braking etc., wherein electromagnetic braking has that braking is sensitive, control is simple, is convenient to the advantage such as automation and is widely adopted, but existing electromagnetic brake does not have dust explosion protection and the defective of gas explosion-proof (d II CT4).
Summary of the invention:
The utility model purpose provides a kind of a kind of anti-explosion is electromagnetic break with the explosion-proof and dust explosion protection function of gas.
The technical solution of the utility model is, a kind of anti-explosion is electromagnetic break, comprise brake axle, braking device and brake shell, terminal box, it is characterized in that: brake shell and end cap thereof and terminal block housings and end cap thereof are flame-proof type, be provided with seal ring between above-mentioned brake shell and the end cap thereof, be provided with the second seal ring between terminal block housings and the end cap thereof, the mating face between brake casing and the bearing (ball) cover, mating face between brake axle and the copper sheathing, mating face between terminal block housings and the terminal box end cap and the mating face between terminal block housings and the brake casing all reach the mating face requirement of gas explosion-proof d II CT4 and dust explosion protection DIPA21TAT4.
The utility model compared with the prior art explosion-proof d II of existing gas CT4 has again the advantage of dust explosion protection.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The function of and dust explosion protection explosion-proof for the gas of realizing electromagnetic brake, the utility model is made into shell and the end cap with explosion insulation performance to terminal block housings 8, brake casing 6 and the end cap 5,7 of existing electromagnetic brake 1, and is provided with the second seal ring bearing (ball) cover 5 outer the settings between seal ring 4, terminal block housings 8 and the terminal box end cap 7 of brake axle.Mating face between brake casing and the bearing (ball) cover, mating face between brake axle 3 and the copper sheathing 2, mating face between terminal block housings 8 and the terminal box end cap 7, mating face between terminal block housings and the brake casing all reaches gas explosion-proof d II CT4 and dust explosion protection DIPA21TAT4 requirement, and the structures such as the braking device of electromagnetic device, brake axle and braking plate are changed.
