The specific embodiment
Shown in Figure 3, automatically the anti-device that slips is by by air compressor 1, total reservoir 2, main reservoir pipe 3, brake activation valve 4, train pipe 5, triple valve 6, brake cylinder 7, auxiliary reservoir 8 and locomotive brake lever 9, brake block 18 constitutes, air compressor 1 is connected with total reservoir 2, total reservoir 2 is connected with brake activation valve 4 by main reservoir pipe 3, total reservoir 2 both can link with train pipe 5 by main reservoir pipe 3 and brake activation valve 4 and also can communicate with atmosphere, train pipe 5 is connected with auxiliary reservoir 8 and brake cylinder 7 by triple valve 6, brake cylinder 7 is connected with brake lever 9, brake block 18 is installed in the end of brake lever 9 near wheel, lockout mechanism is set up on top at brake lever 9, and lockout mechanism is by valve system 10, working cylinder 11, closed-center system 12, self-locking device 14,19 formations of locking block; Described working cylinder 11 is connected with train pipe 5 by valve system 10; Working cylinder 11 is connected with closed-center system 12; Closed-center system 12 is connected with lockout mechanism 14 by connecting rod 13; Locking block 19 is installed on the end of brake lever 9 away from wheel, and self-locking device 14 is located at a side of locking block 19.
When train will start and when carrying out inflation just, pressurized air charges in the working cylinder 11 by check valve 101 and triple valve 15 in the train pipe, oppress the spring 121 in the closed-center system 12 simultaneously, make closed-center system 12 store certain mechanical energy, for anti-slide in the future provides energy source, this moment, connecting rod 13 drive self-locking devices 14 were separated with car brakeing lever 9, and self-locking device 14 is in relieved state.When train arrival stops,, car brakeing cylinder 8 realizes car brakeing thereby will being pressed in wheel by car brakeing lever 9 drive brake blocks 18 from acquisition pressurized air in the auxiliary reservoir.In case locomotive (locomotive engine) is with after train separates, owing to the leakage of the motor vehicle braking system air pressure that causes contracting in the brake cylinder reduces gradually and even disappears, therefore the braking force of 18 pairs of wheels of brake block will be reduced to complete obiteration gradually, thereby may cause slipping the generation of car phenomenon.For fear of the generation of this phenomenon, this moment, hook-shaped pulling block 17 will be oppressed locking block 19 on car brakeing lever 9, provided new braking force source to remedy the deficiency of its braking force that produces owing to the leakage of brake cylinder 7 compressed airs to it.Its principle is: the present most of vehicles of China all are to adopt self acting (compression) air damper, when the locomotive decoupling device is driven away when locomotive brake or after stopping, train pipe 5 logical atmosphere, the end air pressure that check valve 101 links to each other with train pipe 5 will descend or complete obiteration, this moment, gas exhausting valve 102 was opened, pressurized air in the working cylinder 11 will be through triple valve 15, gas exhausting valve 102 is arranged to atmosphere after flow regulating valve 104 time-delays a period of time (scalable), simultaneously the springs 121 in the closed-center system 12 begin to do work and drive self-locking devices 14 tension hook-type pulling blocks 17 by connecting rod 13 and be pressed on the locking block 19, provide new braking force source to avoid slipping the generation of car phenomenon for brake lever 9.Hook-shaped pulling block 17 is connected with closed-center system 12 by connecting rod 13, the braking force that compresses locking block 19 is provided for hook-shaped pulling block 17 by closed-center system 12, and former braking mode is not lost, and the size of its pressure is the conversion power of spring.When vehicle needs brake off, locomotive is inflated to level pressure (500kpa) by train pipe 5 to vehicle, pressurized air in the train pipe 5 also enters in the working cylinder 11 by check valve 101 simultaneously, hook-shaped pulling block 17 oppositely moves under the effect of working cylinder 11, being lifted roller 16 simultaneously lifts, throw off with locking block 19, self-locking device 14 is in relieved state.When the train emergency braking, because the pressure in the train pipe 5 also can reduce to zero, the anti-device that slips also can move, if this moment, the anti-automatically device that slips commenced work without delay, apply an extra braking force for locking block 19, locking phenomenon just might take place because of braking force is excessive wheel is caused damage in motor vehicle braking system, therefore the pressurized airs in the working cylinder 11 are needing progressively arrange to atmosphere through flow regulating valve 104 and then from freeing pipe 103 earlier during to atmosphere by blow off valve 102 rows, can form the regular hour like this to lag behind to guarantee that the anti-device that slips can not start working in the emergency braking process.Gas flow when flow regulating valve 104 can be adjusted exhaust in advance with guarantee anti-slip device only the differential pressure train pipe 5 in to zero and the regular hour of delaying time, just start working the generation of locking phenomenon in the time of also just can avoiding the train emergency braking.
Because gas exhausting valve 102 is just can open exhaust below the near 50kpa of train pipe internal pressure, and the minimum 350kpa that reduces to of pressure in the train pipe during train service braking, this moment, blow off valve 102 can not opened exhaust, and promptly this anti-slide device does not influence the normal brake application of train.
Certainly, valve system 10 can also adopt other structures, and as with check valve 101, shutoff valve 102 is connected with working cylinder 11 respectively, and it also can be several that its quantity can be one.
Certainly, this is anti-to slip device and can also install artificial alleviation mechanism additional, when the vehicle that is in anti-slide state need be shunt grouping operation, can make it to alleviate by artificial alleviation mode.
Self-locking device 14 also can adopt other form, as bearing pin locking, block etc., as long as replenish new braking force can for locking block 19.
Closed-center system 12 be not limited in the present embodiment by spring 121 realize gas can and the mutual conversion of mechanical energy, so long as can realize between gas energy in the working cylinder 11 and the mechanical energy in the closed-center system 12 that other Conversion of energy modes of conversion all fall into protection domain of the present utility model mutually.
