Specific embodiment
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are simplified signal
Figure, only illustrates basic structure of the invention in a schematic way, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of three brake shoes formula traction machine brake sticking brake device, including：It is arranged on the drum on traction machine main shaft
Formula brake, two brake arms of setting symmetrical on drum brake, two brake arms are looped around traction machine main shaft periphery, each
Two ends that brake arm is set are respectively first end and the second end, and first end is alternate to set electromagnetism push rod and spring assembly, the
Two ends are connected a rotating shaft.
Drum brake is provided with brake shoe towards traction machine main shaft one side, and the inner side of each brake arm arc is also provided with
Brake shoe.By in drum brake bottom, the 3rd shoe brake watt, when two brake arms clasp traction machine main shaft, drum brake are set
Device can form downward displacement, the brake shoe of such drum brake bottom just can with the brake shoe in two brake arms synchronously be close to
Traction machine main shaft forms the braking to traction machine main shaft, need not increase brake arm brake shoe with the contact area of traction machine main shaft
In the case of, supplemented by the 3rd shoe brake watt, further increase friction area.
Electromagnet in electromagnetism push rod connection drum brake.
First end sets body, and body is the tube-in-tube structure of one end open, and spring assembly is arranged on body, spring assembly
Including interior setting tripping spring, tripping spring is pressed on set in vivo by an end cap, and end cap is connected drum brake by a slide bar,
Two pieces end cap and drum brake are fixed in slide bar two ends respectively, and slide bar runs through body, and the opening of body is towards drum brake
Outside, end cap is arranged at opening.
Brake shoe on drum brake towards the one side of traction machine main shaft be arcuate structure.Drum brake bottom sets the
Three shoe brakes watt are located at brake shoe centre position in two brake arms, and such three shoe brake watt can be braked with the carrying out of left-right balance.
When power is off, electromagnetism push rod loses the power of electromagnet and is shunk to drum brake, and now tripping spring is by band-type brake
The first end of arm is close to drum brake direction, while two athletic meeting of brake arm synchronously make drum brake to moving down
It is dynamic, it is ensured that the brake shoe on brake shoe and drum brake in brake arm is adjacent to traction machine main shaft and is braked；During energization, electromagnetism
Be lifted off for two brake arm first ends by push rod, and at this moment drum brake is also moved upwards, three shoe brake watt disengaging traction machine main shafts, no
In braking.
It is above enlightenment according to desirable embodiment of the invention, by above-mentioned description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the content on specification, it is necessary to determine the technical scope according to the scope of the claims.
