Part.
As shown in figure 1, traction machine drum brake 100 provided by the utility model, corresponding to be installed on traction machine 200
On, wherein traction machine 200 is the conventional structure of this area, therefore is no longer elaborated.
With reference to shown in Fig. 1-2, the traction machine drum brake 100 includes magnetic apparatus 110, brake scotch 120, brake arm
130 and denoising device 140.Wherein, magnetic apparatus 110 are installed on the upper end of traction machine 200, and its side is convexly equipped with and brake arm
130 corresponding push rods 111；Brake scotch 120 is adjacent on the braked wheel 210 for being installed on traction machine 200, and its lower end is by fixing
Part 150 is fixed on braked wheel 210；One end of brake arm 130 is connected on traction machine 200 by fixing axle 131, brake arm
130 other end is inconsistent with the push rod 111 of magnetic apparatus 110, and brake arm 130 is connected by rotary shaft 132 with brake scotch 120
Connect；The denoising device 140 is located between brake scotch 120 and brake arm 130, when being acted for reducing the drum brake 100
Noise.
In the utility model, fixture 150 is used for brake scotch 120 located at the lower section of rotary shaft 132, the fixture 150
It is fixed on braked wheel 210.Denoising device 140 can adjust brake arm located at the top of rotary shaft 132 by denoising device 140
130 pairs of pressure of brake scotch 120, so as to effectively reduce noise produced when brake arm 130 is acted.
Preferably, fixture 150 is bolt, and the bolt is arranged on brake arm 130 and one end contacts at brake scotch 120,
To fix brake scotch 120.Certainly, fixture 150 is not limited to bolt, can also be other fixed structures.
With continued reference to shown in Fig. 1-2, the denoising device 140 includes bolster 141, buffering spacer 142 and adjustment part
143.Wherein, bolster 141 is resilient structure, and the bolster 141 is located between brake arm 130 and brake scotch 120, and bolster
141 one end is contacted on brake scotch 120；Adjustment part 143 is telescopically connected on brake arm 130, and adjustment part 143 one
The other end of the one end away from the brake scotch 120 for contradicting bolster 141, adjustment part 143 is held to protrude out brake arm 130
Outward；Buffering spacer 142 is held between bolster 141 and adjustment part 143.The adjustment part 143 holds out against buffering spacer 142 to compress
Bolster 141, thus applies larger pressure to brake scotch 120, when 110 dead electricity of magnetic apparatus, can effectively reduce brake arm 130
Produced noise during action, and be adjusted by the adjustment part 143 i.e. can adjust brake arm 130 put on brake scotch 120
Pressure, it is easy to adjust.
With continued reference to Fig. 2, mounting hole 133 is penetratingly offered on the brake arm 130, bolster 141 is installed in the peace
In dress hole 133, and its one end protrudes out mounting hole 133 and contacts on brake scotch 120, and its other end is located in mounting hole 133,
Mounting hole 133 has positioning action to bolster 141, to prevent it from offseting；Buffering spacer 142 is installed in the mounting hole 133
And the end of bolster 141 is contacted at, adjustment part 143 is telescopically connected in the mounting hole 133, and adjustment part 143 is contradicted
In on buffering spacer 142, thus making the buffering spacer 142 be held between bolster 141 and adjustment part 143, by regulation
The adjustment part 143 can adjust the pressure that brake arm 130 is acted on brake scotch 120.
Preferably, the bolster 141 in the utility model is elastic component, specially rubber bodies or spring, but not as
Limit, can also be other similar elastic articles.
Referring again to shown in Fig. 2, the denoising device 140 also includes locking member 144, and the locking member 144 is connected to tune
One end protruded out outside brake arm 130 of one integral piece 143, for axial locking adjustment part 143.
Preferably, adjustment part 143 in the utility model is bolt, and locking member 144 is nut, by bolt, nut
Coordinate, it is convenient to adjust its power acted on buffering spacer 142, it is easy to operate, and low cost.
Further in conjunction with shown in Fig. 1-2, the work to the denoising device 140 of the utility model traction machine drum brake 100
Process is described.
As shown in figure 1, when the drum brake 100 is braked, magnetic apparatus 110 moment dead electricity, the push rod of magnetic apparatus 110
111 thrust disappears, and the elastic force of tripping spring (non-label) makes brake arm 130 be revolved to the direction of braked wheel 210 around fixing axle 131
Turn, during this, due to having gap between brake arm 130 and rotary shaft 132, therefore brake arm 130 can clash into rotary shaft 132
And produce noise；But in the rotary course of brake arm 130, adjustment part 143 can hold out against buffering spacer 142 and compress bolster 141, from
And apply larger pressure on brake scotch 120, as shown in Fig. 2 and then produced making an uproar when effectively reducing by 130 start of brake arm
Sound；Also, by adjusting the adjustment part 143, the relative pressure between brake arm 130 and brake scotch 120, adjustment side can be strengthened
Just.
To sum up, due to denoising device of the present utility model 140, brake arm 130 of its bolster 141 located at drum brake
Between brake scotch 120, and one end of bolster 141 contacts at brake scotch 120；Adjustment part 143 is telescopically connected to braking
On arm 130, and one end of adjustment part 143 is used to contradict one end away from the brake scotch 120 of bolster 141, adjustment part 143
The other end protrude out outside brake arm 130, buffering spacer 142 is held between bolster 141 and adjustment part 143.The adjustment part
143 hold out against buffering spacer 142 to compress bolster 141, so as to apply larger pressure to brake scotch 120, when magnetic apparatus 110 lose
When electric, can effectively reduce brake arm 130 and act produced noise, and be adjusted by reinforcement brake arm by the adjustment part 143
130 pairs of pressure of brake scotch 120, make reasonable stress, and can be adjusted without dismounting, easy to adjust, and the denoising device
140 simple structure, low cost.
Accordingly, the traction machine drum brake 100 with the denoising device 140 also has identical effect.
The structure of the other parts of the utility model traction machine drum brake 100 is ripe for those of ordinary skill in the art
Know, be no longer described in detail herein.
Above disclosed is only preferred embodiment of the present utility model, can not limit this practicality with this certainly new
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and are covered
