Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model slope vehicle disconnected rope safety guard, the two cover brake equipments arranged by corresponding mine car front and back wheel 8 are formed.Two cover brake device structures are identical, share braking voussoir 21 symmetry and install.Often overlap fender guard to be made up of speed control device, wheel wedge-caulking device and track wedge-caulking device respectively.
Wherein speed control device comprise with wheel center is symmetrical, be arranged on brake pawl I 10 in wheel face and brake pawl II 14.The front end of brake pawl I and brake pawl II is welded with centrifugal block for clutch use 12 respectively, there is the ratchet rotating shaft 11 of rotating for brake pawl at the center of brake pawl I and brake pawl II, the front end of brake pawl I is connected by gangbar 13 with the rear end of brake pawl II, the rear end of brake pawl I is connected with centrifugal block for clutch use retracing spring 9 one end by the pipe link that one end and its are hinged, and the other end of centrifugal block for clutch use retracing spring is fixed in wheel face.
Described wheel wedge-caulking device comprises braking voussoir 21, and this braking voussoir is made by metal material, and two cover brake equipments of corresponding front and back wheel share one piece of braking voussoir (as shown in Figure 1).As shown in Figures 2 and 3, the position of the corresponding wheel top edge of braking voussoir 21 is arc, and it is connected with rubber detent sheet 20 sulfuration by spraying binder.As shown in Figure 1 and Figure 4, mine car frame 1 fixedly mounts with screw 17 the braking voussoir guide groove 22 that there is T-shaped slideway inside, the T-shaped slide block on braking voussoir top is placed in the T-shaped slideway of braking voussoir guide groove, make the two form sliding block joint, braking voussoir can horizontally slip in the T-shaped slideway of braking voussoir guide groove.As shown in Figure 1, the end of braking voussoir is connected (this retracing spring resets after braking voussoir brake off) with the scotch block reset spring 23 that one end is fixed in mine car frame.As shown in Figure 2, parallel with two wheel center lines along welding at braking voussoir medial side face lower, the U-lag 16 of opening upwards, brake rod 15 is set in U-lag, one end of brake rod is corresponding with the top edge of wheel, the other end and a brake rod locating dowel pin 19 be fixedly mounted in U-lag hinged, top and one end of brake rod are fixed on the brake rod retracing spring 18 braked on voussoir and are connected.
Composition graphs 1, Fig. 5 and Fig. 6, track wedge-caulking device comprises installation armful rail block 25 in orbit, this armful of rail block is made up of two voussoirs being positioned at track 27 both sides, supported by support spring 26 between two voussoirs, embrace rail block and be placed in the webge slot 7 be fixedly connected with mine car frame, embrace and be equipped with ball 24 between rail block and webge slot, embrace rail block and trigger the tension wheel 5 that controlled by lower track adjusting wheel 6, tensioning spring 4 of rope 3 be connected with the braking voussoir in wheel wedge-caulking device with upper track adjusting wheel 2 by braking.
The principle of work of above-mentioned safety guard is:
If mine car moves right in Fig. 1, wheel clockwise direction rotates, when there is disconnected rope in mine car, mine car moves right speed to be accelerated, wheel produces larger centnifugal force, centrifugal block for clutch use wherein in Fig. 1 on left side wheel braking ratchet under the influence of centrifugal force, brake pawl is rotated clockwise along centnifugal force tangential direction around ratchet rotating shaft, after mine car reaches certain speed, brake pawl II on the wheel of the left side goes to its front end and contacts (now brake pawl II makes centrifugal block for clutch use retracing spring be compressed by gangbar and brake pawl I) with the brake rod front end on the left side, to brake rod one instant impact to the right on the left side, meanwhile, brake pawl also synchronous axial system in a clockwise direction in the wheel of the right, after contacting with the brake rod on the right, to brake rod one instantaneous impact upwards on the right, the brake rod on the right is rotated counterclockwise, (after rotation, under the effect of brake rod retracing spring, recovering former horizontality) around the braking locating dowel pin hinged with it, now the brake rod on the left side moves right under instant impact effect, pull braking voussoir to move right in spacing guide groove, the rubber detent sheet on braking voussoir is contacted with the outer rim of left wheel, along with the mobile wedging left wheel of mine car, wheel is stopped operating, realizes mine car braking function.While braking voussoir moves right; the braking be connected with braking voussoir triggers rope and pulls an armful rail block; make to embrace rail block to be moved to the left along webge slot; two voussoirs embracing rail block are close to each other; with frictionally after guide rail contact by guide rail locking; wheel is shut down, realizes the double insurance of disconnected rope safety guard-safeguard thus.
The effect of the centrifugal block for clutch use retracing spring in speed control device is, disconnected rope pulls back mine car after repairing, and braking voussoir removes the braking to wheel, brake pawl II leaves brake rod, is set back by elastic force promotion brake pawl I and brake pawl II by the centrifugal block for clutch use retracing spring compressed.
