The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As shown in Figure 1, rail car coupler shadoof anti-bouncing device of the present invention, comprise coupling lever 1, uncoupling rod bracket 2 and anti-jump backstop 3, coupling lever 1 is roughly zigzag, coupling lever 1 is through uncoupling rod bracket 2, uncoupling rod bracket 2 is for supporting coupling lever 1, simultaneously for limiting the rotation of coupling lever 1 and takeofing.
As shown in Figure 2, uncoupling rod bracket 2 is comprised of mount pad 5 and supporting seat 6 two parts, and mount pad 5 and supporting seat 6 are structure as a whole, supporting seat 6 is mutually vertical with mount pad 5, mount pad 5 is roughly del, has two fixed orifices 7 on mount pad 5, and bolt is fixedly connected with car body 4 through fixed orifice 7.
As shown in Figure 3, on the supporting seat 6 of uncoupling rod bracket 2, there is a key shaped through hole, the bottom of through hole is the draw-in groove 8 for stoping coupling lever 1 to rotate, draw-in groove 8 is roughly oblong, on coupling lever 1, there is the engagement section 10 matching with draw-in groove 8 shapes, the both sides that are engagement section 10 are plane, and engagement section 10 is stuck in draw-in groove 8 when interior, can limit coupling lever 1 and rotate.The top of through hole is rotation hole 9, and rotation hole 9 is greater than the circular hole of coupling lever 1 diameter for diameter, and coupling lever 1 can freely rotate rotation hole 9 is interior.
As shown in Figure 3 and Figure 4, when vehicle operating, coupling lever 1 is stuck in draw-in groove 8, by anti-jump backstop 3, avoids it in draw-in groove 8, to deviate from.Anti-jump backstop 3 is angular structure, by baffle plate 11 and backstop riser 12, formed, in the present embodiment, baffle plate 11 and backstop riser 12 are preferably the platy structure that is roughly strip shape, adopt angle steel processing or steel plate butt welding to form, to increase the intensity of whole anti-jump backstop 3, and be easy to processing, cost is low.Baffle plate 11 and backstop riser 12 are vertical mutually on horizontal and vertical, and the position being connected with backstop riser 12 at baffle plate 11 adopts arc transition, reduces the stress value of junction.
One backstop circular hole 13 is set on the top of baffle plate 11, realizes being rotationally connected between anti-jump backstop 3 and uncoupling rod bracket 2 at backstop circular hole 13 places by bearing pin 14, anti-jump backstop 3 is rotated around bearing pin 14, realizes the closure of anti-jump backstop 3 and opens two states.For the ease of Assembly &Disassembly, the other end of bearing pin 14 is fixedly connected with by spring cotter 15, between bearing pin 14, spring cotter 15 and baffle plate 11, is provided with packing ring 16, while rotating to reduce anti-jump backstop 3 with uncoupling rod bracket 2 between contact.
At coupling lever 1, be stuck in draw-in groove 8 when interior, the stop surface 19 of baffle plate 11 bottoms is inconsistent with the top of coupling lever 1, the width of baffle plate 11 is greater than the width of draw-in groove 8, it is the width that the width of stop surface 19 is greater than draw-in groove 8, baffle plate 11 plays the effect of restriction on vertical to coupling lever 1, effectively stop coupling lever 1 to be jumped out in draw-in groove 8, avoid vehicle in draw-in groove 8, to jump out under extremity.The side of coupling lever 1 engagement section 10 is plane, 18 of the binding faces of backstop riser 12 sidepieces are fitted with the side of coupling lever 1, for upwards coupling lever 1 being played the effect of restriction in level, more than the width of the binding face 18 of backstop riser 12 is greater than 20mm, to increase the weight of whole anti-jump backstop 3, guarantee the intensity of backstop riser 12, simultaneously, can increase the fitting area of backstop riser 12 and coupling lever 1, avoid the wearing and tearing of 12 pairs of coupling levers 1 of backstop riser in the long-time operation of vehicle.
Due to the setting of backstop riser 12, make the decentralization of whole anti-jump backstop 3, when free state, utilize the gravity of self, make the vertical lower setting all the time of baffle plate 11 and backstop riser 12, stop coupling lever 1 to be jumped out in draw-in groove 8.And, in the present embodiment, the deviation of gravity center backstop circular hole 13 center vertical line of preferred anti-jump backstop 3, as shown in Figure 3, the center of gravity place of anti-jump backstop 3 exists one apart from a between vertical line and backstop circular hole 13 center vertical line, the center of gravity of anti-jump backstop 3 is positioned at the outside of backstop circular hole 13 center vertical lines, due to deviation of gravity center, make anti-jump backstop 3 have in the clockwise direction torque, under the effect of torque, backstop riser 12 can fit tightly with the sidepiece of coupling lever 1 all the time when vehicle operating, further stop coupling lever 1 to be jumped out in draw-in groove 8, greatly improved the safety and reliability of coupling lever 1, ensured guideway vehicle safe in operation.
The bottom of backstop riser 12 has to the curve 17 of coupling lever 1 direction bending, and the setting of curve 17 is more conducive to fit tightly between backstop riser 12 and coupling lever 1, also can improve the aesthetics of whole anti-jump backstop 3 simultaneously.
This apparatus structure is simple, swift and convenient to operate, as long as manually anti-jump backstop 3 is rotated, just can realize rapidly the closure of anti-jump backstop 3 and the switching of opening two states, when closure state, only rely on gravity to realize and stop coupling lever 1 to be jumped out, avoid vehicle automatic uncoupling under extremity.
Closure state: the engagement section 10 of coupling lever 1 is fastened in draw-in groove 8, under free state, anti-jump backstop 3 gravitates, the binding face 18 of backstop riser 12 fits tightly with the side of coupling lever 1, and stop surface 19 stops coupling lever 1 to be jumped from top.
Opening: rotate anti-jump backstop 3 to the top of coupling lever 1, the draw-in groove 8 that now coupling lever 1 can carry away on uncoupling rod bracket 1 enters in rotation hole 9, realizes uncoupling.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
