The specific embodiment
Embodiment one
Shown in Fig. 1-4, present embodiment provides a kind of mining rail guiding double rail device, and this device is made of two parallel wedge shape guide rails, and the wedge shape guide rail is made of guiding rail 1, transition guide 2 and fixed block 3, wherein, and highly along its length gradual change of guiding rail 1; Fixed block 3 cross-sectional planes are inverted U-shaped, has at least one groove 31 along this fixed block length direction setting on one of them madial wall of this fixed block, Figure 4 shows that two grooves 31, be placed with a plurality of balls 32 in this groove 31, groove 31 two ends all have for stoping ball 32 to break away from the block 33 of this groove, and groove 31 degree of depth are along its length direction gradual change, groove than shallow end 331 degree of depth more than or equal to ball 32 radiuses (simultaneously with reference to figure 5); Transition guide 2 is curved, and an end and guiding rail higher-end 11 are hinged, and the other end is captiveed joint with fixed block; The end face 39 of the rail level 19 of guiding rail 1, the rail level 29 of transition guide 2 and fixed block 3 forms a continuous surface.The block 33 of groove 31 1 ends can be wholely set with fixed block 3, the block 33 of the other end can removably connect with fixed block 3, such as being connected by screw, ball 32 can be put into groove 31 from this end before installing, the block 33 that to hold again is connected by screw on fixed block 3, ball 32 can only be moved between two blocks, and can in groove 32, not come off.
The mining rail guiding double rail device that the utility model provides, fixed block with two wedge shape guide rails during use is arranged in respectively on two tracks 10, the transition guide 2 of adjusting arc makes itself and track 10 tangent, and impact the fixed block groove than shallow end 331, as shown in Figure 5, make in the groove ball from its than deep end 332 to moving than shallow end 331, ball is gradually near also final conflict track one side, make the fixed block locking in orbit by ball and another madial wall and conflict of track both sides that groove is not set of fixed block, as shown in Figure 6, with the rail level 19 of tramcar wheel 20 along guiding rail, the rail level 29 of transition guide and the end face 39 of fixed block are finally shifted onto and are finished rerail on the track, impact again at last the fixed block groove than deep end 332, make ball in groove from its than shallow end 331 to moving than deep end 332, thereby disengage with track side surfaces, realize release, return back to state shown in Figure 5, prior art greatly reduces hand labor intensity relatively, realize the safety behind the larger derailing of mine car of load-carrying, the fast speed rerail has improved work efficiency.
Embodiment two
On the basis of embodiment one, the alerting ability that uses in order to increase mining rail guiding double rail device has connection guide rail 4 between guiding rail 1 and transition guide 2; Such as Fig. 7, shown in Figure 8, connection guide rail 4 height are along its length direction gradual change, and connection guide rail is hinged than low side 41 and guiding rail higher-end 11, connection guide rail higher-end 42 is hinged with transition guide 2, and the rail level of the rail level of guiding rail, the rail level of connection guide rail, transition guide and the end face of fixed block form a continuous surface.Like this, in use, can flexibly guiding rail be placed the position adaptive with tramcar wheel according to the position of heavily loaded derailing of mine car, use convenient.Hinged by adopting secondary connection of ball to realize.
For the ball that places in the fixed block groove can be rolled flexibly, the shape of groove 31 and size are all suitable with ball 32.Ball 32 is spherical in shape in the present embodiment, groove 31 is a columniform part, can not break away from groove 31 in order to guarantee ball 32 when the groove 31 interior rolling, and the radius than shallow end 331 degree of depth and ball 32 of groove is suitable, than deep end 332 degree of depth less than ball 32 diameters, as shown in figure 10.
As shown in Figure 9, fixed block 3 has a cambered surface end 34 of outwards giving prominence to, and this cambered surface end is hinged with fixed charge method end plate 5, and this fixed charge method end plate 5 is bolted with transition guide 2.Can finely tune by fixed charge method end plate the angle of transition guide and fixed block, it is tangentially adaptive to be convenient to adjust transition guide and track, increases the alerting ability that mining rail guiding double rail device uses.
Such as Fig. 9, shown in Figure 10, groove 31 be positioned at this cambered surface end 34 than shallow end 331.When mine car under external force in the process that the wedge shape guide rail moves, as shown in figure 11, the thrust that fixed block is subject to is identical with the mine car service direction, ball is subjected to direction opposite with the mine car service direction, if this friction force can overcome the static friction force between ball and the track, thereby then ball moves to the more shallow end of groove with the fixed block locking in orbit, as shown in figure 12, in the process of mine car operation, fixed block is in orbit locked all the time; If groove be positioned at this cambered surface end than deep end, in the process of mine car operation, ball is subjected to direction opposite with the mine car service direction, if this friction force can overcome the static friction force between ball and the track, ball moves to the darker end of groove, might be so that the fixed block release, therefore, above-mentioned structure has been avoided the phenomenon generation that fixed block and track break away from the mine car operational process.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
