Description
Technical field
The present invention relates to wheel-type spreading machine manufacturing technology field, especially a kind of brake equipment of the conveying rotary motion for wheel-type spreading machine.
Background technology
Wheel-type spreading machine is to mix pave uniformly specialized equipment on whole good base course of the cement concrete that makes or bittulith.The service brake of wheel-type spreading machine is used for wheel-type spreading machine in deceleration and the parking of the process of advancing.After wheel-type spreading machine stops, needing braking during standstill, prevent that wheel-type spreading machine from sliding forward or backward.The technical scheme of braking device of wheel-type spreading machine is at present: its change speed gear box is delivered to power respectively on left and right two drive wheels by chain gearing from output shaft, and it is to be realized by a plate disc brake of braking the input shaft connection of change speed gear box that the service brake of this wheel-type spreading machine is connected with braking during standstill.This brake equipment, when in the wheel-type spreading machine driving process, braking rapidly suddenly, as easy as rolling off a log gear pair and the damage of the bearing that causes in the change speed gear box, even cause driving chain to break to cause braking unsuccessfully the danger that therefore can cause wheel-type spreading machine not stop; In addition, owing to from plate disc brake to two drive wheel certain transmission accumulated error is arranged, therefore, braking position is accurate not, has potential safety hazard, when serious train operation accident can occur.
Summary of the invention
It is accurate that problem to be solved by this invention provides a kind of braking position, the braking device of wheel-type spreading machine of reliable operation.
In order to address the above problem, the technical solution used in the present invention is: this braking device of wheel-type spreading machine, include change speed gear box, the output shaft of described change speed gear box is connected with left and right two drive wheels by chain gearing, the input shaft of described change speed gear box is connected with a plate disc brake, on the driven sprocket on described left and right two drive wheels brake wheel is housed all, an axle of captiveing joint with vehicle frame is arranged in each described brake wheel, and the stay bearing plate that connects at described axle is equipped with two rest pins; Two brake shoe brake cheek are housed between described brake wheel and the described axle, one end of every described brake shoe brake cheek is contained on the stay bearing plate by rest pin, between the other end of two described brake shoe brake cheek brake cylinder is housed, two described brake shoe brake cheek and the coupling end of described brake cylinder between extension spring is housed.
In the above-mentioned braking device of wheel-type spreading machine technical scheme, technical scheme can also be more specifically: the exterior arc surface of described brake shoe brake cheek is provided with friction lining.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, the wheel-type spreading machine in travelling has reduced the application force that acts on change speed gear box inner teeth wheel set and the bearing when stopping suddenly, thereby eliminates the damage to gear pair, avoids causing the accident of gear avalanche; Reduced the pulling force that acts on the driving chain, eliminated breaking of driving chain and caused braking failed potential safety hazard;
2, braking device of wheel-type spreading machine acts directly on the lock torque that produces on the drive wheel of both sides, and the wheel-type spreading machine in travelling is stopped, and shortens from braking to the time of stopping, and braking position is accurate, reliable operation.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing embodiment:
Fig. 1, braking device of wheel-type spreading machine shown in Figure 2 include change speed gear box 5, change speed gear box 5 is fixedly mounted on the vehicle frame of wheel-type spreading machine, change speed gear box 5 input shafts are connected with a plate disc brake 4, the output shaft of change speed gear box 5 is connected with drive axle by spline fitted, drive sprocket all is equipped with at the two ends of drive axle, drive sprocket is connected with driven sprocket 3 on the axle 12 of left and right two drive wheels 6 that are contained in the vehicle frame both sides respectively by chain 1, on the driven sprocket 3 on left and right two drive wheels 6, brake wheel 2 is installed all, as shown in Figure 3; An axle of captiveing joint with vehicle frame 12 is arranged in each brake wheel 2, at the stay bearing plate that is welded to connect with axle 12 two rest pins 11 are installed, two brake shoe brake cheek 8 are installed between brake wheel 2 and the axle 12, by screw friction lining 7 are housed on brake shoe brake cheek 8 exterior arc surfaces, such as Fig. 4, shown in Figure 5; One end of every brake shoe brake cheek 8 is contained on the rest pin 11 on the stay bearing plate by borehole jack, and the other end of two brake shoe brake cheek 8 is connected by the piston of bearing pin with brake cylinder 10 two ends respectively, and brake cylinder 10 is fixedly mounted on the driven sprocket; Two brake shoe brake cheek 8 are equipped with the extension spring hole at brake cylinder 10 coupling ends, and the reset extension spring 9 of usefulness of brake shoe brake cheek 8 is housed between two extension spring holes of two brake shoe brake cheek 8.
Wheel-type spreading machine in the process of moving, when chaufeur depresses brake pedal, hydraulic brake master passes to brake cylinder 10 by hydraulic pipe with application force, the piston at brake cylinder 10 two ends is outwards mobile, promoting two brake shoe brake cheek 8 by bearing pin outwards opens, brake shoe brake cheek 8 is pressed to the inwall of brake wheel 2 with movable friction plate 7, thereby makes the mutually friction generation lock torque realization wheel-type spreading machine service brake of inwall applying of exterior arc surface and the brake wheel 2 of friction lining 7; When the application force on the brake off oil cylinder 10, under the effect of extension spring 9, brake shoe brake cheek 8 band movable friction plates 7 unclamp with brake wheel 2, thus brake off.This braking device of wheel-type spreading machine, braking position is accurate, reliable operation.
After wheel-type spreading machine stops, when needing braking during standstill, pull parking brake, the plate disc brake 4 drive change speed gear boxs 5 that are connected with parking brake by middle parts are delivered to lock torque respectively on left and right two drive wheels 6 by chain gear from output shaft, realize braking during standstill.
