On seat 15, fork-shaped locking bar positioning press spring base 15 adjusting screw 14 and frame 4 are positioned by the fork-shaped locking bar that be threadedly coupled with frame 4
Connection.
Described transmission device includes vertical rod 17 and vertical rod drive mechanism；The middle and lower part for the vertical rod 17 that above-below direction is set leads to
Cross bearing pin 22 to be articulated and connected with frame 4, as shown in Figure 9, Figure 10, the bottom of vertical rod 17 is symmetrical fork configuration, fork-shaped
Two bottoms of structure are horizontally set on two connecting rods 23 of the both sides of braking rail 34 by joint ball bearing and fore-and-aft direction respectively
The be hinged installation in rear end；Vertical rod drive mechanism includes driving stage clip 20, and driving stage clip 20 is located at one end positioning top of body inner side
Lean against on the upper outside end face of vertical rod 17, one end positioning that driving stage clip 20 is located on the outside of car body is acted against in frame 4.
As shown in Figure 7, Figure 8, the dynamic wedge that described safety tongs brake apparatus includes safety tongs support 25, mutual wedge surface coordinates
Block 24 and determines voussoir 29；Safety tongs support 25 is arranged on the lower section of frame 4；Dynamic voussoir 24 and determines voussoir 29 are overall relative to braking
Rail 34 is symmetrical set as two groups, and dynamic voussoir 24 is the inner side that pre-small post-large wedge structure is arranged on determines voussoir 29, moves wedge
The lateral surface that the right-angle side of block 24 corresponds to braking rail 34 is set and the right-angle side of dynamic voussoir 24 is provided with wear-resistant slide block, dynamic voussoir
24 are coordinated by guiding mechanism and the wedge surface of determines voussoir 29, and dynamic voussoir 24 can be moved forward and backward in determines voussoir 29 along its wedge surface and realized
Closer or far from braking rail 34, the rear end of dynamic voussoir 24 passes through the be hinged installation in the front end of joint ball bearing and connecting rod 23；Determines voussoir
29 right-angle side is arranged on safety tongs support 25 by horizontally disposed stud 27.
As shown in Fig. 2, Fig. 3, Fig. 5, Fig. 8, this mine car by traction steel wire wire saws normal speed when being travelled, lock pin 12-1
It is entrapped in lockhole 17-1, now fork-shaped locking bar positioning stage clip 16 is in release conditions, driving stage clip 20 is in compression and stores power shape
The side of state, the right-angle side of dynamic voussoir 24 away from braking rail 34, realize the non-locking state of this mine car normally travel.
As shown in Fig. 1, Fig. 4, Fig. 6, Fig. 7, after the wire rope breaking of mine car group is drawn, traction is lost between mine car group
Power, the rotating speed of driving state wheel 1 is more and more faster, and then gear ring 2 is gradually rotated at a high speed with nutating gear 3 and power transmission shaft 5,
Centrifugal globe 11 gradually moves to the radial direction of power transmission shaft 5 under the influence of centrifugal force during power transmission shaft 5 gradually rotates at a high speed
It is dynamic, drive centrifugation bar 7 to tilt drawing tappet 9 in the moving process of centrifugal globe 11 and drive drive sleeve 10 in the spline segment of power transmission shaft 5
Upper outside side slip, when mine car has exceeded the retro-speed of setting, drive sleeve 10 overcomes the elastic force of fork-shaped locking bar positioning stage clip 16
And fork-shaped locking bar is compressed by fork-shaped locking bar 12 and positions stage clip 16, fork-shaped locking bar 12 is pulled in the slipping of drive sleeve 10 along be hinged
The central rotation of pin 13 makes to deviate from lock pin 12-1 self-locking holes 17-1, and vertical rod 17 loses constraint, in the recovery bullet of driving stage clip 20
Under power effect, vertical rod 17 rotates counterclockwise around bearing pin 22, and the fork-shaped bottom of vertical rod 17 in rotary course promotes connecting rod 23 to move forward, even
Bar 23 then promotes wedge surface reach of the dynamic voussoir 24 along dynamic voussoir 24 to make the right-angle side of dynamic voussoir 24 close to the side of braking rail 34,
Mine car is braked in braking rail 34 by the frictional force between the wear-resistant slide block on the right-angle side of dynamic voussoir 24 and the side of braking rail 34
On, realize the locking halted state of this mine car；When locking halted state need to release, opposite direction promotes vertical rod 17 to make it around bearing pin 22
Center turns clockwise while compressible drive stage clip 20, is moved after the fork-shaped bottom pulling connecting rod 23 of vertical rod 17, connecting rod 23 is then drawn
Being moved after dynamic wedge surface of the dynamic voussoir 24 along dynamic voussoir 24 makes side of the right-angle side of dynamic voussoir 24 away from braking rail 34, in addition, fork-shaped
The lock pin 12-1 of locking bar 12 is pushed into complete in the lockhole 17-1 of vertical rod 17 under the recovery elastic force effect of fork-shaped locking bar positioning stage clip 16
Into releasing locking halted state.
In order to prevent this mine car when entry normal speed travels lock pin 12-1 because vibration etc. the improper abjection of reason
Lockhole 17-1, scheme as a further improvement on the present invention, as shown in Fig. 4, Fig. 9, the upper end of described vertical rod 17 is provided with upward
The extension handle section of extension；Described braking prevent-moving car part also includes switching device, and as shown in figure 11, switching device includes flat
Wear the latch 30 for the extension handle section bottom for being connected on vertical rod 17 and the positioning being correspondingly arranged in frame 4 in driving wheel axis direction
Hole；Mine car is needed when entry transports, and operating personnel can rearward promote the extension handle section of vertical rod 17 to make from front
Vertical rod 17 turns clockwise around the center of bearing pin 9, side of the right-angle side of dynamic voussoir 24 away from braking rail 34, when latch 30 aligns machine
Latch 30 is inserted in the positioning hole in frame 4 to the positioning that vertical rod 17 can be achieved during positioning hole on frame 4.
In order to prevent positioning hole of the latch 30 in 17 positioning states of vertical rod because of the improper disengaging frame 4 of the reasons such as vibration,
Scheme as a further improvement on the present invention, as shown in figure 11, described latch 30 is spaced that to be provided with two circles trapezoidal in the axial direction
Locating slot, in described vertical rod 17 it is corresponding be located at be provided with screw close to the position of the trapezoidal locating slot of the afterbody of latch 30, in screw
Positioning screw 33, spring 32 and steel ball 31 are sequentially provided with from the outside to the core, and steel ball 31 is acted against in the trapezoidal locating slot of latch 30；When
Latch 30 is in insert state during 17 positioning states of vertical rod, and steel ball 31 is acted against positioned at the trapezoidal locating slot close to the afterbody of latch 30
It is interior；When 17 non-locating state of vertical rod, latch 30 is in extraction state, and steel ball 31 is acted against positioned at the ladder close to the head of latch 30
In shape locating slot, it can prevent latch 30 from losing.
In order to slow down impulsive force of the wear-resistant slide block to the side of braking rail 34, so realize prevent wear-resistant slide block Fast Wearing,
Extend the service life of wear-resistant slide block, as a further improvement on the present invention scheme, the right-angle side and peace of described determines voussoir 29
Buffer spring 28 is set between full pincers support 25, and buffer spring 28 can make the frictional force that acts on the side of braking rail 34 gradual
Increase.
Do not consolidate with not deflecting to ensure determines voussoir 29 in the presence of buffer spring 28 and move horizontally, be used as this hair
Bright further improvement project, as shown in Figure 12 and Figure 13, between the rear and front end of described determines voussoir 29 and safety tongs support 25
It is equipped with the guiding mechanism worked in coordination.
In order to realize that regulation two pieces dynamic voussoir 24 is identical with the gap between the two sides of braking rail 34, and then unbalance loading is prevented,
