As shown in Fig. 2, Fig. 3, Fig. 5, Fig. 8, Figure 10, this mine car is locked when being travelled by traction steel wire wire saws normal speed
Pin 12-1 is entrapped in lockhole 17-1, and now fork-shaped locking bar positioning stage clip 16 is in release conditions, drives stage clip 20 to be in compression
Power state, the right-angle side of dynamic voussoir 25 are stored in the state away from the side of track 36, realize the non-locking of this mine car normally travel
State.
As a example by positioned at the braking prevent-moving car part in front, as shown in Fig. 1, Fig. 4, Fig. 6, Fig. 9, when the steel of traction mine car group
After the disconnected rope of cord, tractive force is lost between mine car group, the rotating speed of driving state wheel 1 is more and more faster, and then drive gear ring 2 and passed
Moving gear 3 and power transmission shaft 5 gradually at a high speed rotate, power transmission shaft 5 gradually at a high speed rotate during centrifugal globe 11 centrifugal force work
Gradually moved to the radial direction of power transmission shaft 5 under, drive centrifugation bar 7 to tilt drawing tappet 9 in the moving process of centrifugal globe 11
The outside side slip on the spline segment of power transmission shaft 5 of drive sleeve 10 is driven, the drive sleeve when mine car has exceeded the retro-speed of setting
10 overcome fork-shaped locking bar to position the elastic force of stage clip 16 and compress fork-shaped locking bar by fork-shaped locking bar 12 positions stage clip 16, drive sleeve 10
Fork-shaped locking bar 12 is pulled in slipping to be made to deviate from lock pin 12-1 self-locking holes 17-1 along the central rotation of swivel pin 13, vertical rod 17
Constraint is lost, under the release elastic force effect for driving stage clip 20, vertical rod 17 drives connection around the center rotate counterclockwise of connecting shaft 22
The circumferential rotate counterclockwise of axle 22, connecting shaft 22 drives pole 23 to elapse drivening rod 24 forwards and moves forward in rotary course, connecting rod
24 then promote dynamic voussoir 25 to be moved forward along the wedge surface of dynamic voussoir 25 makes the right-angle side of voussoir 25 near the side of track 36, such as schemes
Shown in 9, dynamic voussoir 25 continues the safety tongs support 26 that moves forward and then drive after the right-angle side of dynamic voussoir 25 contacts 36 side of track
The overall guiding mechanism for setting in left-right direction is moved horizontally and the medial surface for determining brake pad 31 is also contacted the side of track 36, moves wedge
By moving the wear-resistant slide block on the right-angle side of voussoir 25 and determining the resistance to wear smooth on the medial surface of brake pad 31 during the continuation reach of block 25
Frictional force between block and the two sides of track 36 brakes on track 36 mine car, realizes the locking halted state of this mine car；Embrace
When dead halted state need to be released, opposite direction promotes vertical rod 17 it is turned clockwise around the center of connecting shaft 22 and drives connecting shaft 22 weeks
To turning clockwise, while compressible drive stage clip 20, connecting shaft 22 drives pole 23 to rotate clockwise, and pole 23 passes through joint ball
Bearing pulls the connecting rod 24 voussoir 25 is moved to body inner side direction, moves voussoir 25 in the constraint for moving voussoir guide plate 25-1 similarly hereinafter
When away from track 36 side, in addition, the lock pin 12-1 of fork-shaped locking bar 12 fork-shaped locking bar positioning stage clip 16 recovery elastic force make
Locking halted state is released with completion in the lockhole 17-1 of lower push-in vertical rod 17.
Braking prevent-moving car component working principle and process and the above-mentioned braking prevent-moving car part positioned at front being located behind
Similar, simply direction symmetrically changes, and no longer describes herein.
In order to prevent this mine car when entry normal speed is travelled lock pin 12-1 because vibration etc. the improper abjection of reason
Lockhole 17-1, as further improvement of the utility model scheme, as shown in figure 4, the upper end of described vertical rod 17 is provided with upwards
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
The driving wheel axis direction latch 32 for wearing the extension handle section bottom for being connected on vertical rod 17 and the positioning being correspondingly arranged in frame 4
Hole；When entry is transported, operating personnel can rearward promote the extension handle section of vertical rod 17 to make to stand to this mine car from front
Bar 17 turns clockwise around the center of connecting shaft 22, the right-angle side of dynamic voussoir 25 away from track 36 side, when latch 32 aligns machine
Latch 32 is inserted the positioning that vertical rod 17 is capable of achieving in the location hole in frame 4 during location hole on frame 4.
In order to prevent latch 32 in 17 positioning states of vertical rod because of the improper location hole for departing from frame 4 of the reasons such as vibration,
Used as further improvement of the utility model scheme, as shown in figure 11, described latch 32 is spaced is provided with two circles in the axial direction

The position of 26 outboard end is provided with reseting pressuring spring 26-1, and reseting pressuring spring 26-1 one end positioning is acted against in frame 4, other end positioning
Act against on the outboard end of safety tongs support 26；Being moved during on-position during voussoir 25 moves forward drives safety tongs support 26 overall
The guiding mechanism for setting in left-right direction is moved horizontally makes the medial surface for determining brake pad 31 also contact the side of track 36, now resets
Stage clip 26-1 is in compressive state, is moved after voussoir 25 is moved when brake release, and safety tongs support 26 is answered reseting pressuring spring 26-1's
Elastic force effect lower integral level movement in position resets.
In order to realize being easy to regulation gap to make the right-angle side of voussoir 25 and determine 36 liang of the medial surface and track of brake pad 31
Gap between side is identical, and then realizes more preferable braking effect, as further improvement of the utility model scheme, such as
Shown in Fig. 8, Fig. 9, Figure 10, the position of the outboard end of correspondence safety tongs support 26 is additionally provided with horizontal level and determines in described frame 4
Position screw 27, horizontal level Positioning screw 27 is threadedly coupled with frame 4 and is set between horizontal level Positioning screw 27 and frame 4
There is locking nut；By adjusting the extension elongation of the horizontal level Positioning screw 27 at the two ends of safety tongs support 26 or so and passing through lock
Tight nut locking, can conveniently adjust the left and right horizontal position of safety tongs support 26, and then realize being easy to the dynamic voussoir of regulation two pieces
Gap between 25 and the two sides of track 36.
Described dynamic voussoir 25 can be provided on safety tongs support 26 with the guiding mechanism for determining the cooperation of the wedge surface of voussoir 30
