Braking catcher also comprises a connecting rod 5 and a brake rod 14, and pull bar 1 is hinged by bearing pin I4 with one end of connecting rod 5, and it is hinged that the other end of connecting rod 5 and the medium position of brake rod 14 pass through bearing pin II13;
Brake rod 14 comprises two symmetrical slippers, one end of two slippers is linked together by brake axle 20, on brake axle 20, cover has the brake sleeve 21 that can rotate around it, brake sleeve 21 cooperatively interacts with the teeth groove on braking orbit 27, the other end of brake rod 14 has rectangle adapter sleeve 14-1, rectangle adapter sleeve has slotted hole, and axletree 15 is hinged with it through the slotted hole on rectangle adapter sleeve 14-1; The below of frame 2, the top of brake rod 14 have the limiting stopper 22 of restriction brake rod position.
The connection diagram of pull bar 1 and connecting rod 5 as shown in Figure 4.
The situation of rope or unhook once generation winch haulage cable breaks, connecting bridge before or after braking car just loses tractive force, under the elastic restoring force effect of stage clip I6, guide plate 8 drives pull bar 1 to slide in the mounting hole of frame 2, pull bar 1 drivening rod 5 rotates around hinge-point, connecting rod 5 pulls brake rod 14 to rotate around axletree 15, the brake axle 20 of brake rod one end is brought into together with brake sleeve 21 in the teeth groove of braking orbit 27, thus stop the descending sport car of mine car, reach the object of braking rapidly; When mine car recovers traction, the elastic force that pull bar 1 overcomes stage clip I6 moves forward at the mounting hole of frame 2, pull bar 1 drivening rod 5 rotates backward around hinge-point simultaneously, connecting rod 5 pulls brake rod 14 to rotate backward around axletree 15, the brake axle 20 of brake rod one end departs from braking orbit 27 together with brake sleeve 21, arresting between end bearing pin 20 and sleeve 21 due to brake rod is friction of rolling, so brake rod hinders moment little, so brake rod easily can produce from tooth-like track in the formula that produces from tooth-like track; Limiting stopper 22 is for limiting the end position of lever connection; Tractive force, for limiting the end position of pull bar in car haul process, is applied directly in frame by pull bar by block 3, and all the other rod members do not stress.What the brake equipment in this mine car adopted is simple mechanical drive, and without the need to separately establishing power, volume is little, low cost of manufacture, is easy to install, and is convenient to safeguard; Owing to being immediately arrest completely, arrest rear to mine car, track inclined shaft two side apparatus and personnel without any damage.
As shown in Figure 1 and Figure 2, blind hole in rectangle adapter sleeve 14-1 is circular, stage clip II17 is fixed in rectangle adapter sleeve 14-1 by plug screw 19 and back-up ring 18 by one end of blind hole, and the other end of stage clip II17 connects a slide plate 16, and described slide plate 16 contacts with axletree 15 all the time; The both sides of axletree 15 limit rectangle adapter sleeve 14-1 with fixing back-up ring 28 and detachable back-up ring 29 and move.
During braking, brake rod 14 rotates at the hinge-point place with axletree 15, axletree 15 relative sliding in the slotted hole of rectangle adapter sleeve 14-1, promote slide plate compression press spring II simultaneously, by braking force buffer action on axletree 15, thus the mild braking of realization braking car is on the tooth-like track in centre, is connected in braking car mine car group below and also brakes in orbit.
Owing to axletree being fixed the spacing of back-up ring and removable back-up ring, do not de-orbit when brake rod 14 moves in elongated hole line of centers all the time, and detachable back-up ring facilitates brake rod dismounting and change simultaneously.
As shown in Figure 1, Figure 3, the frame 2 of mine car is also provided with switching mechanism, described switching mechanism comprises eccentric wheel 12, eccentric shaft 11 and driving lever 10, eccentric shaft 11 is passed the through hole in frame 2 and is connected by key with eccentric wheel 12, eccentric shaft 11 is connected by key with driving lever 10, and driving lever 10 to rotate around the hole in frame 2 with movable eccentric wheel 12 and eccentric shaft 11 and contacts when cutting out and braking catcher with pull bar 1 end.
When mine car transports in gallery time, can utilize switching mechanism that brake equipment is closed, driving lever 10 is with movable eccentric wheel 12 to rotate by eccentric shaft 11, eccentric wheel 12 is moved to mine car working direction by pushing drawing rod 1, pull bar 1 drivening rod 5 rotates clockwise, connecting rod 5 drives brake rod 14 to rotate counterclockwise and brake axle 20 and brake sleeve 21 is pulled out from the teeth groove of braking orbit 27, thus closes brake equipment, makes mine car can forwards transportation smoothly.
As shown in Figure 3 and Figure 5, one end of driving lever 10 has fixed orifice, frame 2 has two symmetrical knock holees 26, and locating dowel pin 9 is fixed on the knock hole 26 of frame 2 through the fixed orifice on driving lever 10; Locating dowel pin 9 connects with driving lever 10 is dynamic, the bearing pin of locating dowel pin 10 has two circular grooves, the side of driving lever 10 has tapped bore, and one end of screw 25 connects a steel ball 23 by spring 24, screw 25 is arranged in tapped bore, and steel ball 23 and one of them circular groove cooperatively interact; Driving lever 10 is with when wherein side knock hole is connected, and eccentric wheel 12 extrudes pull bar 1 and cuts out braking catcher.
Pulled out outside knock hole 26 frame 2 by locating dowel pin 9, due to the elastic force of spring, steel ball 23 and another on locating dowel pin 9 enclose annular opening and engage and fixed by locating dowel pin, and now driving lever 10 is unfettered; Then rotating lever 180 °, and being inserted by locating dowel pin 9 on another knock hole 26, steel ball and another on locating dowel pin enclose annular opening and engage and can prevent locating dowel pin from losing.
Further, uniform some annular knurls on the outer circumference surface of brake sleeve 21.The friction force between brake drum and braking rack guide rail can be improved, make deceleration and stopping performance more reliable.
Working process is as follows
As shown in Figure 1, when eccentric wheel 12 is in shown position, described braking catcher is in opening, prosthomere mine car draws mine car in diagram by pull bar 1 and advances, pull bar is along the mounting hole parallel motion in frame until block 3 contacts with frame 1, now stage clip I6 is in compressive state, and pull bar drives brake rod to be in and limiting stopper 22 contact condition by connecting rod; When there is the traction winch wire rope breaking of traction mine car group, pull bar 1 loses tractive force, and under the elastic restoring force effect of stage clip I6, pull bar 1 is to car rear to movement; Pull bar 1 move drivening rod 5 backward around bearing pin I4 counterclockwise movement, connecting rod 5 drives one end of brake rod 14 to rotate clockwise around axletree 15 by bearing pin II13, brake axle 20 and the brake sleeve 21 of brake rod 14 other end are stuck in the teeth groove of braking orbit 27, owing to axletree being fixed the spacing of back-up ring 28 and detachable back-up ring 29, do not de-orbit when brake rod 14 moves along slotted hole line of centers, makes brake sleeve 21 hang on braking orbit 27; Meanwhile, the stage clip II17 inside rectangle adapter sleeve 14-1 promotes slide plate 16 thus by braking force buffer action on axletree 15, realization brakes the mild braking of car on the tooth-like track in centre, is connected in braking car mine car group below and also brakes in orbit.
When mine car transports in gallery, utilize switching mechanism will brake catcher and close, locating dowel pin 9 is extracted from the knock hole 26 frame 2, driving lever 10 is rotated 180 °, and locating dowel pin 9 to be inserted in frame 2 in another knock hole 26; Be with movable eccentric wheel 12 to compress pull bar 1 until block 3 contacts with frame 2 in the process that driving lever 10 rotates, pull bar 1 drives brake rod 14 to be in by connecting rod 5 to continue up with limiting stopper 22 exposure level position limitation brake rod; Braking catcher no longer plays a role after cutting out, and mine car can transport smooth running under non-brake state.
