Detailed description of the invention
For making the effectiveness of the clearer understanding of those skilled in the art inventive principle of the present invention and concrete means.Technological means, creation characteristic that the present invention realizes, reach object and effect is easy to understand, below in conjunction with concrete accompanying drawing, set forth the present invention further.
With reference to Figure of description 2; label 9 represents tunnel; that is can directly be laid in tunnel 9 according to the automobile-used speed runaway protection system of trackless rubber-tyred of the present invention; specifically in inclined gallery; can arrange as common rail mining car buffer stop, and need not special tunnel be set.
Why can arrange like this, be that it has specific structure, specifically refer to Figure of description 1 to 5, the automobile-used speed runaway protection system of a kind of trackless rubber-tyred, its basic structure comprises:
Drag hook, one end is gib head 11, as shown in Figure 3, the other end is connected with corresponding pedestal by bearing pin 16 and drag hook is rotated around bearing pin 16, and wherein pedestal is used for drag hook being arranged on railless free-wheeled vehicle 2, for being arranged on the vehicle frame at the bottom of railless free-wheeled vehicle 2 car in figure, also the tailstock can be arranged on, but headstock may be made to upwarp at the tailstock, be unfavorable for stablizing, recommend the bottom of frame be arranged on as shown in Figure 3.
Pass through said structure, drag hook is just provided with the degree of freedom rotated around bearing pin 16, state so shown in Fig. 3, due to gravity or External Force Acting, drag hook can be pulled up or fall (being left railless free-wheeled vehicle 2 working direction in Fig. 3), gib head 11 can brush away the ground in tunnel 9, and according to this constructional feature, the necessary partial configuration of other institutes is as follows:
First be lockout mechanism, for locking after described bearing pin 16 is lifted to predetermined altitude at drag hook, lift is to level attitude as shown in Figure 3, departs from ground certain altitude, avoids producing with ground interfering.
Then configure lock-off mechanism, correspondingly with described lockout mechanism to connect, driving lockout mechanism lock-off, and drag hook is fallen from predetermined height.
As everyone knows, the lockout mechanism merely for locking position can not be too complicated, and the lockout mechanism that is corresponding to this case can not too complex, therefore configures relatively simple.And for lock-off mechanism, then can drive the locking component of lockout mechanism, both mate setting.
About lock-off, automatic lock-off can be adopted, also can adopt manual lock-off, about automatic lock-off, can coordinate with speed sensor, when railless free-wheeled vehicle 2 axle speed exceedes setting value, Negotiation speed sensor sends on-off signal, drives lock-off mechanism action, thus lockout mechanism is unlocked.
Another kind is then Non-follow control, during Non-follow control, according to general theory, as control lever should be arranged in the operator's compartment of railless free-wheeled vehicle 2, conveniently operates.
It is below arresting portion, direct employing obstruction rope 8, block compared to the face of rail mining car, the stop formation of the single obstruction rope 8 of coupling drag hook is simply too much, as shown in Figure 2, obstruction rope 8 transverse direction is laid in pre-position, tunnel 9, thus backwardness catches on this obstruction rope 8 under drag hook, and position can with reference to the setting position of rail mining car in inclined gallery.
For trackless drift, the existence of obstruction rope 8 can not affect the normal operation of free-wheel car.
Obstruction rope 8 adopts steel rope.
The obstruction rigidity of simple obstruction rope 8 is too sufficient, therefore configures energy absorber 5, as shown in Figure 2, is respectively provided with one at obstruction rope 8 two ends, and stops fag end with respective end and be connected.
Here energy absorber is sport car energy absorber, and those skilled in the art should have this and clearly understands.
Fall about drag hook, himself be steel beam column, conduct oneself with dignity larger, but for the benefit of railless free-wheeled vehicle 2 is current ground, tunnel, be generally hard surface, simple deadweight of leaning on can produce beating of drag hook, likely causes hook to draw and does not live obstruction rope 8.
For the problems referred to above, in gib head 11 end device one counterweight, can corresponding reduction beat, but counterweight can add increase load.
Counterweight is selected as one, can be understood as the falling direction mating described drag hook, is furnished with the tightening device providing pulling force in this direction.
Tightening device is all to provide power, and counterweight is to provide downward power equally.But counterweight can not increase responding ability, speed of response can not increase in other words.
If providing source is from outside power, then can improve the acceleration/accel that gib head falls, a kind of selection is fallen by mechanical drive again, and by the driving of such as motor, adopt as four-bar mechanism, drag hook formation rocking bar, allows it fall.
Another kind of mode is Direct driver bearing pin 16, and gib head 11 is hurtled down.Motor drives lower backwardness, and can produce reverse damping, running part also can produce reverse damping simultaneously, and gib head 11 is beated and can be effectively suppressed.
But said structure cost is relatively large, especially may burn out motor, although braking time is shorter, can be burnt out to avoid motor by the mode cutting off motor after braking.
In view of this, in certain embodiments, adopt simple elastomeric element to realize the introducing of external force, as described in tightening device be the extension spring 17 being connected to drag hook thrown wall, acutangulate configuration between this extension spring 17 and drag hook.
Elastomeric element can also adopt as rubber rubber band easily produces corresponding pulling force.

Further about extension spring 17, further describe for effect be drag hook come off with during earth surface or drag hook with vehicle advance process in because of upspringing of jolting and produce, cause and depart from ground, cause the phenomenon that cannot tangle the obstruction rope be connected with energy absorber.The version of extension spring 17 also can adopt following two kinds of modes:
1, torsion spring is installed at bearing pin 10 place, and the power being acted on drag hook by torsion spring prevents drag hook in vehicle advance process from upspringing, and causes and departs from ground, cause the phenomenon that cannot tangle the obstruction rope be connected with energy absorber.
2, strengthen drag hook own wt, rely on himself weight to upspring to prevent drag hook 7 in vehicle advance process, cause and depart from ground, cause the phenomenon that cannot tangle the obstruction rope be connected with energy absorber.
Further about described drag hook, comprise described gib head 11 and coupler body 18, as shown in Figure 3;
Wherein coupler body 18 is herringbone coupler body, as shown in Figure 4, thus to there being the bearing pin 16 of two coaxial line configurations, this structure is conducive to keeping the stable of drag hook, meanwhile, due to the existence of two bearing pins in left and right, the torsional shear square reducing bearing pin axis is to the damage of pin shaft hole and bearing pin, keep gib head 11 to move straight down, thus ensure that hook draws the reliability blocking rope 8.
Further, in order to improve the antitorque ability of cutting, between two legs of described coupler body 18, be connected with the stirrup 19 for strengthening framework intensity.
About drag hook, then in the structure improved further, described gib head 11 is provided with the anticreep plate 10 be arranged on by retracing spring in gib head.
Gib head 11 position as shown in Figure 3, anticreep plate 10, under the power of doing of torsion spring is used, contacts with drag hook all the time.When obstruction rope enters in hook, block obstruction rope by anticreep plate, prevent the obstruction rope entering hook from deviating from.
The structural principle of drag hook: time 1, for avoiding drag hook to be connected with vehicle, interferes with the object below vehicle compartment.So drag hook and bearing pin 16 bearing make a kind of curved shape (also the bearing pin fixed orifice of the pedestal of bearing pin can be placed, flat shape made by drag hook) herein downwards.
2, the length of coupler body horizontal segment is selected by institute's mounting vehicle situation, must ensure that gib head has sub-fraction to expose compartment, so that human users when linking up with.
3, gib head is divided into coupler body and returns hook portion, wherein returns hook portion and is designed to arc-shaped, be convenient to obstruction rope and enter coupler body smoothly.Gib head envisaged underneath becomes inclined-plane, ensures that gib head fully contacts with ground after landing, and prevents gib head and produces nose and leak the phenomenon of hanging obstruction rope 8.Gib head bevel angle is determined according to coupler body length and setting height(from bottom).
As previously mentioned, the one of described retracing spring is selected to be torsion spring, other spring also can be adopted to reset, as the spring of push-and-pull action, as extension spring, configure the right side of anticreep plate 10 in the drawings.
About described energy absorber 5, for going out the energy absorber of rope structure, institute's rope stretching is wound on the reel in energy absorber, and reel to be engaged with fixing friction disc by the friction disc on its output shaft and provides friction energy-dissipating.Can with reference to the energy absorber described in Chinese patent ZL200920226434.8.
