In the left side of oil storage tank 8 and 6 junction of pipeline, so that the hydraulic oil 12 inside braking clamp 1, pipeline 6 and oil storage tank 8 does not have pressure
Power, and after push rod 7 is by the junction of oil storage tank 8 and pipeline 6, push rod 7 will block the outlet of oil storage tank 8, persistently push away
The dynamic pressure that just will increase inside braking clamp 1 is fixedly connected with branch pipe 9, consolidates on branch pipe 9 between the right side and pipeline 6 of oil storage tank 8
Dingan County is equipped with check valve 10, and the inside of valve body 101 is fixedly connected with casing 103, the bottom inside casing 103 by connecting rod 102
End fixed placement has core bar 104, and the periphery of core bar 104 is wound with coil 105, and the top of core bar 104 is solid by second spring 106
Surely it is connected with metal block 107, the top of metal block 107 is fixedly installed with ball 108, when original state, 107 He of metal block
Ball 108 is in contact under the action of second spring 106 with the nozzle of branch pipe 9, realizes the sealing effect for branch pipe 9,
So that the hydraulic oil 12 in pipeline 6 can not be entered in oil storage tank 8 by branch pipe 9, when being reduced by inertia force, counterweight touches ball
113 can not just be powered to coil 105, and check valve 10 is again switched off under the action of 12 pressure of second spring 106 and hydraulic oil,
During push rod 7 persistently pushes, the frictional force between brake strip 3 and brake disc 5 will be increased again, to reach pair
In the effect of the intermittent braking of train, the injury for caused by passenger in compartment of the unexpected braking deceleration of train is avoided.
Inertia trigger device 11, the right side inside framework 111 are fixedly connected between check valve 10 and the rear end of braking clamp 1
Counterweight is fixedly connected with by third spring 112 and touches ball 113, and the right end of counterweight touching ball 113 is connected by electric wire 114 with power supply
It connects, the left side inside framework 111 is fixedly connected with electric shock piece 115, and when train braking, counterweight touches ball 113 in the effect of inertia
Under will pull third spring 112 and be moved to the left, and when severity of braking is excessive, counterweight touches ball 113 will be with electric shock 115 phase of piece
Contact, electric shock piece 115 are connected by electric wire 114 with coil 105, after counterweight touching ball 113 is contacted with electric shock piece 115, energy
It is enough to be powered to coil 105, by the design of inertia trigger device 11, when braking force of train is spent it is big when, counterweight can be made to touch
Ball 113 contacts after pullling third spring 112 under biggish inertia with electric shock piece 115, realizes for 10 interior loop of check valve
105 energization, to metal block 107 and ball 108 be attracted downwards, so that check valve 10 is opened, to reduce brake
Pressure inside vehicle pincers 1, reduces the frictional force between brake strip 3 and brake disc 5, avoids wheel by locking, improves
Braking effect of the brake clamp for train, the train braking of abrasion when reducing to(for) track.
When in use, when needing to brake train, the promotion forward for keeping push rod 7 lasting by control device, when
Push rod 7 is by the way that behind the junction of oil storage tank 8 and pipeline 6, push rod 7 will block the outlet of oil storage tank 8, and pass through check valve 10
Effect, the hydraulic oil 12 in pipeline 6 can not also be entered in oil storage tank 8 by branch pipe 9, to make pipeline 6 and braking clamp 1
Inside become a closed space, push rod 7 push during, will make two sides piston 2 drive brake strip 3 to
Centre is mobile, squeezes it to brake disc 5, to realize the braking effect for wheel, and when brake force is excessive, makes vehicle
When wheel is by locking, the counterweight touching ball 113 in framework 111 is pullled third spring 112 under the action of inertia force and is connect with electric shock piece 115
Touching will make power supply and coil 105 be in energized state during contact, to make core bar 104 generate magnetism, and will
The metal block 107 and ball 108 at top adsorb downwards, and the hydraulic oil 12 in pipeline 6 is flowed in oil storage tank 8,
To reduce the pressure inside braking clamp 1, reduces the frictional force between brake strip 3 and brake disc 5, avoid wheel
By locking, and when inertia force is insufficient to allow counterweight touching ball 113 to pull third spring 112 and electric shock piece 115, core bar 104 is with regard to nothing
Method attracts metal block 107 and ball 108 to move down, and hydraulic oil 12 can not be just flowed into again in oil storage tank 8, be held in push rod 7
During continuous promotion, the frictional force between brake strip 3 and brake disc 5 will be increased again, to reach for train
The effect of intermittent braking avoids train and brakes the injury for caused by passenger in compartment suddenly.
