Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, the disconnected rope safety guard of slope vehicle of the present invention, two arranged by corresponding mine car front and back wheel 8
Set brake unit is constituted.Two sets of brake device structures are identical, share a braking voussoir 21 and are symmetrically installed.Often set protection device is divided
It is not made up of speed control device, wheel wedge-caulking device and track wedge-caulking device.
Wherein speed control device includes that with wheel center be symmetrical brake pawl I 10 in wheel face and braking
Ratchet II 14.The front end of brake pawl I and brake pawl II is respectively welded centrifugal block for clutch use 12, brake pawl I and brake pawl
Link the rear end that there are the ratchet rotating shaft 11 rotated for brake pawl, the front end of brake pawl I and brake pawl II in II center
Bar 13 connects, and the rear end of brake pawl I is connected with 9 one end of centrifugal block for clutch use back-moving spring by the connecting rod that one end is hinged with which,
The other end of centrifugal block for clutch use back-moving spring is fixed in wheel face.
The wheel wedge-caulking device includes braking voussoir 21, and the braking voussoir is made by metal material, corresponding front and back wheel
Two sets of brake units share one piece braking voussoir (as shown in Figure 1).As shown in Figures 2 and 3, on the corresponding wheel of braking voussoir 21
The position at portion edge is arc, is connected with the sulfuration of rubber system moving plate 20 by spraying binder thereon.As shown in Figure 1 and Figure 4, exist
Inside is fixedly mounted with screw 17 in mine car frame 1 the braking voussoir gathering sill 22 of T-shaped slideway, by the T on braking voussoir top
Shape slide block is placed in the T-shaped slideway of braking voussoir gathering sill, makes the two formation be slidably connected, and braking voussoir can be led in braking voussoir
Horizontally slip in the T-shaped slideway of groove.As shown in figure 1, the end of braking voussoir is fixed on the braking in mine car frame with one end
Voussoir back-moving spring 23 is connected (back-moving spring releases reset after braking for braking voussoir).As shown in Fig. 2 in scotch
In the middle part of block, the lower edge of side welds, U-lags of opening upwards 16 parallel with two wheel center lines, arranges system in U-lag
Lever 15, one end of brake bar are corresponding with the top edge of wheel, and the other end and one are fixedly mounted on the braking in U-lag
Bar spacer pin 19 is hinged, and the brake bar back-moving spring 18 that the top of brake bar is fixed on braking voussoir with one end is connected.
In conjunction with Fig. 1, Fig. 5 and Fig. 6, track wedge-caulking device includes installing armful rail block 25 in orbit, and this armful of rail block is by position
In two voussoir compositions of 27 both sides of track, supported by support spring 26 between two voussoirs, embrace rail block and be placed in and mine car frame
In the wedge-shaped slot 7 being fixedly connected, embrace and between rail block and wedge-shaped slot, be equipped with ball 24, embrace rail block and led by braking under trigger tether 3 passes through
It is connected to the tensioning wheel 5 and upper directive wheel 2 of the control of wheel 6, tensioning spring 4 with the braking voussoir in wheel wedge-caulking device.
The operation principle of above-mentioned safety guard is：
If mine car is moved right in Fig. 1, rotationally clockwise, when mine car occurs disconnected rope, mine car is moved right wheel
Speed is accelerated, and wheel produces larger centrifugal force, and the centrifugal block for clutch use in wherein Fig. 1 on left side wheel braking ratchet is in centrifugal force
Under effect, brake pawl is made to rotate clockwise along centrifugal force tangential direction around ratchet rotating shaft, after mine car reaches certain speed,
Brake pawl II on the wheel of the left side go to its front end contact with the brake bar front end on the left side (now brake pawl II by connection
Lever and brake pawl I are compressed centrifugal block for clutch use back-moving spring), to one instant impact to the right of brake bar on the left side；
At the same time, the also synchronous axial system in a clockwise direction of the brake pawl in the wheel of the right, after being contacted with the brake bar on the right, is given
One instantaneous impact upwards of brake bar on the right, makes the brake bar on the right make counterclockwise around the braking spacer pin being hinged with which
Rotate, (in the presence of brake bar back-moving spring, after rotation, recovering raw water level state)；Now the brake bar on the left side was rushed in moment
Hit, pull braking voussoir to move right in spacing gathering sill, make the rubber detent on braking voussoir
Piece is contacted with the outer rim of left wheel, with the mobile wedging left wheel of mine car, is made wheel stop operating, is realized mine car braking work
Energy.While braking voussoir is moved right, the braking trigger tether being connected with braking voussoir is pulled embraces a rail block, makes to embrace a rail block edge
Wedge-shaped slot is moved to the left, embrace rail block two voussoirs close to each other, with guide rail contact after frictionally by guide rail locking, stop wheel
Only operate, be achieved in the dual fail-safe of disconnected rope safeguard protection.
The effect of the centrifugal block for clutch use back-moving spring in speed control device is after disconnected rope is repaired, to pull back mine car, brake voussoir
The braking to wheel is released, brake pawl II leaves brake bar, the centrifugal block for clutch use back-moving spring for being compressed promotes braking by elastic force
Ratchet I and brake pawl II set back.
