Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, 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 in zigzag, coupling lever 1 is through uncoupling rod bracket 2, uncoupling rod bracket 2 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 made up 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 roughly in del, mount pad 5 has two fixed orifices 7, and bolt is fixedly connected with car body 4 through fixed orifice 7.
As shown in Figure 3, the supporting seat 6 of uncoupling rod bracket 2 has 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, coupling lever 1 has the engagement section 10 with draw-in groove 8 mating shapes, namely the both sides of engagement section 10 are plane, when engagement section 10 is stuck in draw-in groove 8, can limits 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 freely can rotate in rotation hole 9.
As shown in Figure 3 and Figure 4, when vehicle operating, coupling lever 1 is stuck in draw-in groove 8, avoids it to deviate from draw-in groove 8 by anti-jump backstop 3.Anti-jump backstop 3 is angular structure, be made up of baffle plate 11 and backstop riser 12, in the present embodiment, baffle plate 11 and backstop riser 12 are preferably roughly the platy structure of strip shape, angle steel processing or steel plate butt welding is adopted 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, adopt arc transition, reduce the stress value of junction at the position that baffle plate 11 is connected with backstop riser 12.
Arrange a backstop circular hole 13 on the top of baffle plate 11, realize being rotationally connected between anti-jump backstop 3 and uncoupling rod bracket 2 at backstop circular hole 13 place by bearing pin 14, anti-jump backstop 3 is rotated around bearing pin 14, realizes the closed 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, bearing pin 14, is provided with packing ring 16 between spring cotter 15 and baffle plate 11, to reduce contact when anti-jump backstop 3 is rotated and between uncoupling rod bracket 2.
When coupling lever 1 is stuck in draw-in groove 8, stop surface 19 bottom baffle plate 11 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, namely the width of stop surface 19 is greater than the width of draw-in groove 8, baffle plate 11 plays the effect of restriction on vertical to coupling lever 1, effective prevention coupling lever 1 is jumped out in draw-in groove 8, avoids vehicle to jump out in draw-in groove 8 under extremity.The side of coupling lever 1 engagement section 10 is plane, the binding face 18 of backstop riser 12 sidepiece is fitted with the side of coupling lever 1, for upwards playing the effect of restriction to coupling lever 1 in level, the width of the binding face 18 of backstop riser 12 is greater than more than 20mm, to increase the weight of whole anti-jump backstop 3, ensure the intensity of backstop riser 12, simultaneously, the fitting area of backstop riser 12 and coupling lever 1 can be increased, the wearing and tearing of backstop riser 12 pairs of coupling levers 1 in avoiding vehicle to run for a long time.
Due to the setting of backstop riser 12, make the decentralization of whole anti-jump backstop 3, when being in 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 center vertical line of the deviation of gravity center backstop circular hole 13 of preferred anti-jump backstop 3, as shown in Figure 3, a distance a is there is in the center of gravity place of anti-jump backstop 3 between vertical line and the center vertical line of backstop circular hole 13, the center of gravity of anti-jump backstop 3 is positioned at the outside of backstop circular hole 13 center vertical line, due to deviation of gravity center, anti-jump backstop 3 is made to there is torque in the clockwise direction, 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 prevention coupling lever 1 is jumped out in draw-in groove 8, substantially increase the safety and reliability of coupling lever 1, ensure guideway vehicle safe in operation.
The bottom of backstop riser 12 has the curve 17 bending to coupling lever 1 direction, and the setting of curve 17 is more conducive to fitting 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 rotated, just can realize rapidly the switching of the closed of anti-jump backstop 3 and unlatching two states, when closure state, only rely on gravity to realize stoping 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, in a free state, anti-jump backstop 3 gravitate, 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: the top rotating anti-jump backstop 3 to 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, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
