Dynamic leading screw 24 connects, and braking screw 24 passes through leading screw moving guide rail 21 and stop-nut 23, leading screw moving guide rail 21 and braking spiral shell
There is the tripping spring 22 compressed between mother 23, tripping spring 22 is sleeved in braking screw 24.During braking, artificial rotation system is needed
The dynamic release of leading screw 24 compression spring 22, brakes the reaction force for braking flashboard 20 by compression spring 22, and when startup is also required to
Artificial rolling brake leading screw 24.Though above device solves the problems, such as mine car static brake, manual operation is required for extremely
Inconvenience, and manual operation is braked, when worker is busy, easily human negligence general idea is forgotten to brake mine car.
In addition, easily occur mine car unhook, steel rope breaking etc. during prolonged production and transport or under misoperation
Phenomenon, so as to cause mine car sport car i.e. mine car to be swept away at a terrific speed from slope and overturn or the sport car for the worker that wounds
Accident.Above device can not solve the problems, such as mine car sport car.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of be automatically prevented from mine car car slipping, sport car mine car braking dress
Put.
The technical solution adopted by the present invention to solve the technical problems is：Mine car brake device, it includes braking flashboard, the
One piston rod, piston, second piston bar, piston cylinder, elastic damping device, end cap and piston guide ring；The piston cylinder both ends
Run through, the piston guide ring is installed at piston cylinder port, the end cap be threadedly coupled with piston cylinder and with piston guide ring
Outer end face contacts；The piston is installed in piston cylinder, and the First piston bar is symmetricly set on piston two with second piston bar
Hold and extend to outside end cap, the First piston bar termination is connected with braking flashboard；The braking flashboard arcuate brake face is equipped with
Brake block；The elastic damping device is installed in piston cylinder and is connected with piston and piston guide ring.
Further, the end cap is additionally provided with dust scraping ring.
Preferably, the elastic damping device is spring, and the spring pocket is in First piston bar or second piston bar.
The beneficial effects of the invention are as follows：A kind of mine car brake device of the present invention, under inactive state, fills by elastic damping
The reaction force put makes mine car be in on-position, it is not necessary to which manual operation, reduces influence of the artificial factor to mining safety.
When mine car stops or traction steel rope of cable is broken, by the reaction force of elastic damping device mine car can be made to be in automatic braking shape
State, can prevent sport car and accident occurs.A kind of mine car brake device of the present invention, braking is simple and convenient, improves mine car operation
When security.

Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in Figure 2 to Figure 3, mine car brake device, it includes braking flashboard 31, First piston bar 32, piston 33, second
Piston rod 34, piston cylinder 35, elastic damping device 36, end cap 37 and piston guide ring 38；35 both ends of piston cylinder are run through, institute
Piston guide ring 38 is stated to be installed at 35 port of piston cylinder, the end cap 37 be threadedly coupled with piston cylinder 35 and with piston guide ring
38 outer end faces contact；The piston 33 is installed in piston cylinder 35, and the First piston bar 32 is symmetrically set with second piston bar 34
Put at 33 both ends of piston and extend to outside end cap 37,32 termination of First piston bar is connected with braking flashboard 31；The braking
31 arcuate brake face of flashboard is equipped with brake block 311；The elastic damping device 36 be installed in piston cylinder 35 and with piston 34 and
Piston guide ring 38 connects.
Piston 33 is installed in piston cylinder 35 and is slidably matched therewith, and piston guide ring 38 is slidably matched with piston rod, and
It is fixed by end cap 38 in 35 port of piston cylinder.First piston bar 32 is symmetricly set on 33 both ends of piston with second piston bar 34
And extend to outside end cap 37, piston can be structure as a whole with piston rod, can also use and be threadedly coupled.Elastic damping device 36 can be
Spring, rubber etc., the effect of elastic damping device 36 are：An active force is provided for piston and piston rod, promotes piston and work
Stopper rod moves, and braking flashboard 31 is compressed 2 wheel hub of wheel, and 2 wheel hub of wheel produces braking moment with the friction of brake block 311.
Operation principle：Mine car brake device 3 is installed on 1 bottom plate of mine car car body, and braking flashboard 31 is set away from 2 wheel hub of wheel
Appropriate location, the second piston bar 34 of the brake apparatus 3 of mine car can be connected by steel cable 7 with adjacent mine car or pulling equipment 5.Root
According to mine car weight, the braking suitable elastic damping device 36 of selection such as power size, under mine car normal rest state, piston 33 and
For piston rod from tractive force, elastic damping device 36 acts on piston rod and piston 33, braking flashboard 31 is compressed the car of mine car
2 wheel hubs are taken turns, mine car is in on-position, prevents that mine car is slippery.When mine car starts, the tractive force of steel cable 7 can be more than elastic damping
Device 36 is to the reaction force of piston 33 and piston rod, so that piston 33 and piston rod move, braking flashboard 31 leaves wheel 2
Wheel hub, mine car start.When the fracture suddenly of steel cable 7 or stop constantly, 7 tractive force of steel cable disappears, the anti-work of elastic damping device 36
Firmly promote piston 33 and piston rod return automatically, braking flashboard 31 compresses 2 wheel hub of wheel, and mine car automatic braking, prevents mine car
Sport car and manual operation is not required, braking is simple and convenient, and mine car operation is safer.
Dust etc. enters in piston cylinder 35 in order to prevent, improves mine car brake device service life, reduces abrasion, further
, end cap 37 is additionally provided with dust scraping ring 39.Sealed by dust scraping ring 39 and scrape off dust on piston rod, reduced dust and enter, reduce
Piston rod is worn.
For the ease of replacing, selection and maintenance etc., preferable elastic damping device 36 be spring, and the spring pocket is mounted in the
On one piston rod 32 or second piston bar 34.Piston rod can also be oriented to spring, spring is acted on piston centre, and can prevent
The crooked fracture of spring.
