Side is also provided with brake shoe.
In one preferred embodiment of the utility model, the electromagnetism push rod connects the electromagnet in the drum brake.
In one preferred embodiment of the utility model, the first end sets body, and the body is the set of one end open
Barrel structure, the spring assembly are arranged on body.
In one preferred embodiment of the utility model, the spring assembly includes interior setting tripping spring, the braking bullet
Spring is pressed on set in vivo by an end cap, and the end cap passes through a slide bar and is connected drum brake.
In one preferred embodiment of the utility model, two pieces end cap and drum brake are fixed in the slide bar both ends respectively,
The slide bar runs through the body.
In one preferred embodiment of the utility model, the opening of the body towards the outside of the drum brake,
The end cap is arranged on the opening.
In one preferred embodiment of the utility model, the one side of brake shoe towards traction machine main shaft on drum brake is arc
Shape structure.
The utility model solves defect present in background technology, and the utility model possesses following beneficial effect:
(1)By setting the 3rd shoe brake watt in drum brake bottom, when two brake arms clasp traction machine main shaft, drum
Formula brake can form downward displacement, and the brake shoe of such drum brake bottom can be with same with the brake shoe in two brake arms
Step is close to traction machine main shaft and forms braking to traction machine main shaft, need not increase contact of the brake arm brake shoe with traction machine main shaft
In the case of area, supplemented by the 3rd shoe brake watt, further increase friction area.
(2)Drum brake bottom the 3rd shoe brake watt of setting brake shoe centre position in two brake arms, such three pieces
Brake shoe with left-right balance can brake.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples;
Fig. 1 is the structure chart of preferred embodiment of the present utility model;
In figure:1st, drum brake;2nd, traction machine main shaft;3rd, brake arm;4th, first end;5th, the second end;6th, electromagnetism push rod;
7th, body;8th, tripping spring;9th, slide bar;10th, end cap;11st, rotating shaft;12nd, brake shoe.
Embodiment
The utility model is described in further detail presently in connection with drawings and examples, these accompanying drawings are simplified
Schematic diagram, only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the structure relevant with the utility model
Into.
As shown in figure 1, a kind of three brake shoe formula traction machine brake sticking brake devices, including:The drum being arranged on traction machine main shaft
Formula brake, two brake arms are symmetrically set, two brake arms are looped around traction machine main shaft periphery, each on drum brake
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 setting the 3rd shoe brake watt, when two brake arms clasp traction machine main shaft, drum brake in drum brake bottom
Device can form downward displacement, and the brake shoe of such drum brake bottom can be to be synchronously close to the brake shoe in two brake arms
Traction machine main shaft forms the braking to traction machine main shaft, need not increase brake arm brake shoe and 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 both ends respectively, and slide bar runs through body, and the opening of body is towards drum brake
Outside, end cap is arranged on opening.
The one side of brake shoe towards traction machine main shaft on drum brake is arcuate structure.Drum brake bottom sets the
Three shoe brakes watt brake shoe centre position, such three shoe brake watt in two brake arms with left-right balance can brake.
When power is off, electromagnetism push rod loses the power of electromagnet and 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 the athletic meeting of two brake arms synchronously makes drum brake to moving down
It is dynamic, ensure that the brake shoe on brake shoe and drum brake in brake arm is adjacent to traction machine main shaft and braked;During energization, electromagnetism
Two brake arm first ends are lifted off by push rod, and at this moment drum brake also moves upwards, three shoe brake watt disengaging traction machine main shafts, no
Braking.
