Wheel dead astern, and respectively connect a brake 13 on its top.
The trigger device includes static determinacy block 3, centrifugal-block 2,4 three parts of resetting spring.Static determinacy block 3 is that four outsides are set
The iron block for having insulator is connected in the border circular areas outside wheel, and four static determinacy blocks 3 are sequentially connected by conducting wire 5；
When reaching certain speed in mine car traveling, centrifugal-block 2 can be under the influence of centrifugal force along preset limit on wheel wheel disc
Position groove movement, front can be inserted into static determinacy block 3 and be attached thereto into a closed circuit, and hereafter signal is just conducted to controller
In 7, rear portion then is avoided getting an electric shock by insulating materials outsourcing, and tail portion has resetting spring 4 to be connected to wheel shaft 6, when brake is completed
And after so that speed is declined, centrifugal force is not enough to centrifugal-block being inserted into static determinacy block 3, at this point, the effect of resetting spring 4 is just by centrifugal-block
2 pull out from static determinacy block 3, and closed circuit disconnects.
The controller 7 includes cylindrical sucked type electromagnet 16, accumulator 17 and external box of microvave.Accumulator 17 is placed
In the position that babinet keeps left, cylindrical sucked type electromagnet 16 is situated immediately in its right side, and the two is filled by conducting wire 5 and triggering
It sets and is connected into a closed circuit；In 7 babinet of rear end inserting controller of front brake bar 11, and it is flat with the sucker on front side of electromagnet
Row is placed, and the front end of rear braking rod is placed in parallel with the sucker on rear side of electromagnet also in 7 babinet of inserting controller.Work as triggering
The signal of device is passed to by conducting wire 5 to controller 7, is equivalent to form a closed circuit, and accumulator 17 discharges at this time,
16 front and rear sides sucker of cylindrical sucked type electromagnet all has magnetism, before the rear end of front brake bar 11 and rear braking rod
End is parallel with the sucker of electromagnet, to be attracted on sucker.
The front and back brake lever is Y-shaped, and the divergent ends of front brake bar 11 are placed on front axle 8, front brake bar 11
The other end be inserted into control cabinet in, the divergent ends of rear braking rod are placed on back axle 9, and the other end of rear braking rod is also inserted into control
In case processed；The body of rod is arranged by buckle 15 on two axles, and the buckle 15 is that both ends are fixed on axle, intermediate drum
The laminated structure risen, the body of rod are partially passed through from 15 intermediate musters of buckle, are arranged in the Y-shaped crotch of front brake bar 11
Resetting spring 14, this resetting spring 14 are connected to front axle 8, and resetting spring 14 is also arranged in rear braking rod Y-shaped crotch, this
Resetting spring 14 is connected to back axle 9.
The brake 13 is respectively to cross out one section of body of rod to front vehicle wheel from the both ends of the Y-shaped branch of preceding brake lever 11
Front, and a brake 13 is respectively connected on its top, the both ends of the Y-shaped branch of rear braking rod 12 also respectively cross out one
The section body of rod respectively connects a brake 13 to rear wheel dead astern, and on its top.
The operation principle of the self-actuating brake of the utility model mine car and speed control unit is：When mine car is run, vehicle wheel rotation
Centrifugal force is will produce, as the mine car speed of service increases, the centrifugal force that vehicle wheel rotation generates can also increase therewith, due to centrifugal force
Effect, the centrifugal-block 2 on trigger device will be moved along preset limiting groove on wheel wheel disc, when speed further adds
Soon, centrifugal-block 2 can be finally inserted into static determinacy block 3 by centrifugal force, when all centrifugal-blocks 2 are inserted into static determinacy block 3, due to four
Static determinacy block 3 is connected by conducting wire 5, and trigger device acts at this time, and then by signal transduction to controller 7, trigger device is by leading
Line 5 is connected into closed circuit with accumulator 17 and cylindrical sucked type electromagnet 16 again, and trigger device action is equivalent to whole
The switch of a circuit is closed, and after power on circuitry, cylindrical sucked type electromagnet 16 is just provided with magnetism, due to front brake bar 11
Rear end is parallel with the front end of electromagnet sucker, so being just attracted on sucker after being powered, since the front end of front brake bar 11 is
It is connected with brake 13, so when current brake lever 11 is attracted backward by sucker, front brake device 13 acts on, at the same time, after
The front end of brake lever 12 is also parallel with the rear end of electromagnet sucker, so being also attracted on sucker after being powered, due to rear braking
The rear end of bar 12 is also to be connected with brake 13, so when rear braking rod 12 is attracted backward by sucker, rear braking device 13
It acts on simultaneously, mine car brake.With the progress of brake, the mine car speed of service reduces, the centrifugal force that vehicle wheel rotation generates
It can reduce therewith, resetting spring 4 just starts effect by centrifugal-block 2 from the pull-out of 3 position of static determinacy block at this time, and closed circuit end is opened, electricity
Magnet loses magnetism, and is set to the resetting spring 14 of the Y-shaped crotch of front brake bar 11 and rear braking rod 12 just by front brake
Bar 11 and rear braking rod 12 are returned to home position respectively, and brake stops, although declining rapidly in the speed short time at this time,
But it is out of service to mine car to be unlikely to brake, so mine car can be with a lower speed after reforwarding after brake stops
Row, this guarantees the controls of the auto-speed of mine car.
