Description
Technical Field
The utility model relates to a rolling door machine technical field especially relates to a rolling door machine dual-brake disc.
Background
At present, electric rolling doors are installed in places such as factories, storefronts, markets, fire fighting passageways, garages and the like, the electric rolling doors are driven by rolling doors, the rolling doors are lifted in place or stopped midway, the rolling doors are stopped, and meanwhile, the rolling doors are braked by a brake system, otherwise, due to the self weight of the rolling doors, the rolling doors fall down, so that in the brake system of the rolling doors, a brake disc is the most critical safety part, and the quality of all braking effects plays a decisive role; once the brake disc has a problem, the brake disc can fall quickly, and even the situation that personnel and articles are injured by crashing occurs. At present, electric roller shutter door's metal door plant weight is big, and braking factor of safety requires highly, and at present, the brake disc surface that uses is smooth plane, and braking effect is not good, can appear skidding, has a lot of potential safety hazards.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art's is not enough, provides a rolling door machine double-brake disc.
The utility model discloses a realize through following technical scheme: a double-brake disc of a door rolling machine comprises a brake disc and a cylindrical fixed seat; the axis of the fixed seat is provided with a rotating shaft fixed hole; one side of the brake disc is fixed on the end surface of one side of the fixed seat, and the other side of the brake disc is fixedly provided with a friction plate; the other side of fixing base is equipped with fixed step boss, fixed step boss is fixed with the metal brake disc, and the metal brake disc is equipped with the louvre.
Furthermore, the metal brake disc is fixed on the fixed step boss through a screw.
And reinforcing ribs are arranged on the brake disc and the fixed seat.
The utility model has the advantages that: compared with the prior art, a brake disc is additionally arranged on the fixed seat of the brake disc to form double braking, so that the braking force of the brake disc is increased, and the braking safety of the door rolling machine is ensured.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1-4, an embodiment of the present invention is a double-brake disc for a door roller, including a brake disc 1 and a cylindrical fixing seat 2; a rotating shaft fixing hole 3 is formed in the center of the fixing seat 2; one side of the brake disc 1 is fixed on the end surface of one side of the fixed seat 2, and the other side of the brake disc 1 is fixedly provided with a friction plate 4; the opposite side of fixing base 2 is equipped with fixed step boss 5, fixed step boss 5 is fixed with metal brake disc 6, and metal brake disc 6 is equipped with louvre 7.
In this embodiment, the metal brake disk 6 is fixed to the fixed step boss 5 by a fixing bolt 8.
In this embodiment, the brake disc 1 and the fixing seat 2 are provided with reinforcing ribs 9.
The utility model discloses the theory of operation of brake disc: the electromagnetic brake wheel of the door roller is subjected to friction braking by the elastic force of the brake spring and the friction plate 4, and in addition, a brake caliper arranged on the shell of the door roller and a brake disc 6 are clamped tightly for braking to form double braking, so that the braking safety of the door roller is improved.
Compared with the prior art, the utility model, increase a brake disc 5 on 6 fixing bases 2, form two brakeings, increase the braking power of rolling door machine, guarantee rolling door machine brake safety.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
