Back-up ring acts against in location nut 23-5；After the wear-resistant slide block 21-2 of splined shaft 21-1 axle head weares and teares, by adjustment bolt 23-
Location nut 23-5 on 4 makes adjustment spring 23-3 haul brake baffle 12-2, make travelling disc spring support 12 overall along guiding
Moving right perpendicular to braking rail 22 direction of groove acts against on limiting plate 23-1, by adjusting the position of limiting plate 23-1, can
To control the gap of the wear-resistant slide block 21-2 of track two side shifting and the both sides of braking rail 22.
Do not work to realize braking catcher in entry transportation when mine car, as this utility model
Further improvement project, as shown in Fig. 4, described braking catcher also includes switching mechanism, and switching mechanism includes partially
Heart wheel 15, eccentric shaft 16 and driving lever 14, eccentric shaft 16 passes through the installing hole coupling in frame 3 and passes through key and eccentric 15 phase
Even, eccentric shaft 16 is connected by key with driving lever 14, and driving lever 14 rotates around the hole of frame 3 with movable eccentric wheel 15 and eccentric shaft 16,
Eccentric 15 is contacted when mine car travels forward with rocking bar 1；When mine car can be by switch in entry transportation
Brake unit is closed by mechanism, and driving lever 14 carries movable eccentric wheel rotation by eccentric shaft 16, and eccentric passes through to extrude rocking bar 1, a side
Face can make rocking bar 1 contact with the baffle plate 2 in frame, and the pull strength on rocking bar 1 is applied to mine car by baffle plate 2 and couples frame
On, on the other hand pass through driving gear pair, screw pair drives brake assemblies 21 away from braking rail 22.
For the ease of controlling driving lever 14, as further improvement of the utility model scheme, as shown in Fig. 4 and Fig. 6, institute
The one end of the driving lever 14 stated has fixing hole, connection frame 3 has two symmetrical location holes, alignment pin 17 passes through on driving lever
Fixing hole be fixed in connection frame 3 location hole on；Alignment pin 17 is moved with driving lever 14 and couples, the bearing pin of alignment pin 17
On have two cannelures, the side of driving lever has screwed hole, and one end of screw 18 connects a steel ball 20, spiral shell by spring 19
Nail 18 is arranged on screw thread in the hole, and steel ball 20 is cooperated with one of cannelure；By alignment pin 17 from connection frame 3
Location hole pulls out outward, and due to the elastic force of spring 19, steel ball 20 engages alignment pin is solid with another circle looping pit on alignment pin 17
Fixed, now driving lever 14 is unfettered；Then 180 ° of rotating lever alignment pin is inserted on another symmetrical location hole, steel ball
Engage with another circle looping pit on alignment pin and can prevent alignment pin from losing.
In the middle of this band, the driving gear pair of the unidirectional disc spring brake type mine car of braking rail can be arranged on left side or right side, with
Under the driving gear pair shown in by Fig. 3 be arranged on left side as a example specifically describe its work process：
As shown in figure 3, shown position is in on-position, and (i.e. mine car passes through brake assemblies 21 and inclined shaft braking rail 22
Frictional force brakes mine car group in braking rail 22), switching mechanism is in closed mode as shown in Figure 2,4.
When pull strength is delivered on rocking bar 1 anterior mine car, as shown in Fig. 2, rocking bar 1 is with respect to connection frame 3 to ore deposit
Along rotating clockwise, rocking bar 1 drives sector gear 6 to rotate clockwise by rocker shaft 5 to car direction of advance, female thread lower tooth set 7
Counterclockwise rotates；As shown in figure 3, the screw thread pair of brake axle 21-3 and lower tooth set 7 is left-handed, brake assemblies 21 with travelling
It is mobile spline connection between disc spring support 12, when lower tooth covers 7 rotate counterclockwise, brake axle 21-3 drives brake assemblies 21 edge
Spline to move away from braking rail 22 to the right, disc spring group 11 is in compressive state, so that brake assemblies 21 leave braking rail
22 so that produce a gap between braking rail 22 and brake assemblies 21, the size in this gap depend on rocking bar 1 and baffle plate 2 it
Between distance.
When anterior mine car loses pull strength suddenly, due to the elastic restoring force of disc spring, disc spring group 11 promotes brake assemblies
On 21 sides being pressed on braking rail 22, by the wear-resistant block 21-2 on brake assemblies 21 and brake baffle 12-2 and braking rail 22
Frictional force between medial surface realizes mine car braking, due to the positive revesal not self-lockings of multi-thread screw mechanism, therefore brake assemblies
21 drive brake axle 21-3 move linearly and drive lower tooth set 7 reverse rotation by screw pair, and lower tooth set 7 is nibbled with sector gear 6
Crossed belt shakes bar 1 and shakes to car rear direction with respect to frame 3, and its result is the distance between the two section mine cars that furthered, due to this
When whole mine car group there is no external pull strength, be so that mine car is mutually furthered by rocking bar 1 pulling force, so design calculate when, shake
The size of bar 1 pulling force will be suitably.
When mine car is in entry transportation, by switching mechanism, brake unit can be closed, as shown in fig. 6,
The location hole from frame 3 for the alignment pin 17 is extracted from inside to outside, steel ball 20 is engaged with another circle looping pit on alignment pin 17, will
Positioning finger setting, now, key shifting lever 14 is unfettered, as shown in Fig. 4,180 ° of rotating levers 14 clockwise, driving lever 14 passes through
Key drives eccentric shaft 16 to rotate, as shown in Fig. 2 eccentric shaft 16 passes through the 180 ° of rotations of key band movable eccentric wheel, eccentric 15 passes through to squeeze
Pressure rocking bar 1 one aspect makes rocking bar 1 contact with baffle plate 2, and the pull strength on rocking bar 1 is applied directly to the frame 3 of mine car by baffle plate 2
On, on the other hand pass through sector wheel set, screw pair drives brake assemblies 21 to depart from braking rail 22.
In the middle of this band, the unidirectional disc spring brake type mine car of braking rail is restricted or is broken off relations once occurring winch haulage cable to break
Situation, mine car front end coupling part loses pull strength, and rocking bar 1 loses restraining forceies, and rocking bar 1 drives rocker shaft 5 to pass through bearing
Shake with respect to frame 3, due to multi-thread screw mechanism revesal not self-locking, by between driving gear pair and brake axle 21-3
, so that the disc spring group 11 in travelling disc spring support 12 loses restraining forceies, disc spring group 11 is in the effect of spring force for screw transmission system
The lower contacts side surfaces promoting brake assemblies 21 and braking rail 22, by brake assemblies 21 and brake baffle 12-2 and braking rail 22 side
Frictional force between face by running car tramcar brake in braking rail 22, braking catcher due to be using be arranged on left side or
Brake assemblies 21 braking rail 22 that is pointed between two tracks on right side carries out holding tightly braking, and therefore structure is simple, low cost, just
In I＆M, it is particularly well-suited to coal mine inclined shaft hauling operation.
