Four, the specific embodiment
Referring to accompanying drawing 1-3, the electronic anti-skid stopping device of single track bar gravity lifting described in the utility model is made up of driving and reversing mechanism 17, joist 10, end carriage 1, braking rail 3, the pincers 5 that float, float support 6, supporting member 7, symmetrical lifter etc.End carriage 1 is installed in an end of cement pillow, and an end of joist 10 is connected with end carriage 1, the other end is fixing with non-unsteady stock rail 8, the side stock rail that end carriage is installed for the size of float stock rail 2, its braking force by should unsteady stock rail generation.The pincers 5 that float are contained in the inboard, joist 10 grooves of the stock rail 2 that floats, and are held by main shaft 4 pincers 5 that will float by elevator 23.Floating, support 6 one ends are connected with main shaft 4, the other end is connected with hinge axis 16.Supporting member be contained in non-unsteady stock rail 8 the inboard, by the roller 19 of lifting arm-tie II 18 hold, the other end is connected with hinge axis 15.The advance and retreat plate laterally is connected with hinge 13,14, vertically is connected with driving and reversing mechanism 17 with advance and retreat pull bar 11.Driving and reversing mechanism 17 is installed in the middle of equipment and is connected with pin and front and back advance and retreat plate 12.Braking rail 3 is installed in the pincers 5 and above the supporting member 7 of floating, bolt up respectively.The symmetry lifter is energy storage type shown in Figure 3 advance and retreat devices, is contained on the plane of joist 10 inboards, and an end is held main shaft 4, and the other end is stuck in the groove below the supporting member 7.
Wherein, energy storage type advance and retreat device structure principle chart is seen Fig. 3: reducing motor output shaft 29 is connected, drives advance and retreat leading screw 25 with advance and retreat nut 27 and does straight reciprocating motion, and the leading screw 25 of advancing and retreat simultaneously is connected with front and back advance and retreat plate 12 with the two ends of pull bar 31 to be done inwardly or outwards to be synchronized with the movement.Before and after advance and retreat plate 12 by hinge axis 15 is connected with hinge 13, hinge 13 by hinge axis 15 be connected with supporting member 7, other end hinge 14 passes through hinge axis 16 and is connected with unsteady support 6.Advance and retreat plate 12 inwardly during motion before and after the glancing impact, hinge 13,14 promotes supporting members 7, floats and support 6 to two lateral movements.Opposite during alleviation with braking.In the time of above vehicle is parked in equipment: actuating unit can not put in place fully, this moment closed-centre system with energy storage, its principle is: energy storage arm-tie 24 is connected, passes through pull-rod nut 28 compressed energy-storage springs 26 with energy storage with spring pull bar 30, and the compressive force of energy stroage spring 26 passes to float support 6 and 7 pairs of car brakeings of supporting member by energy storage arm-tie 24, pull bar 31, front and back advance and retreat plate 12, hinge 13,14 simultaneously.When vehicle wheel when leaving equipment, the stored energy of energy stroage spring will will float by spring pull bar 30, energy storage arm-tie 24, pull bar 31, front and back advance and retreat plate 12, hinge 13,14 and support 6 float pincers 5 supporting members 7 and braking rail and enter complete braking mode.Float rail gravity state when next round just is in during to access arrangement this moment.
The working process of this stopping device is:
(1) braking: when anti-slide device is received brake command, the motor right-hand revolution.Advance and retreat plate 12 was along the inwardly motion of track alignment symmetry before and after driving and reversing mechanism 17 made, front and back advance and retreat plate 12 drives two hinges 13,14 and rotates around hinge axis 15,16, promote to float support 6, unsteady pincers 5 and supporting member 7, braking rail 3 simultaneously to two lateral movements, reach automatic blocking behind the retarder location, the lifting arm-tie III20 of supporting member 7 drive lifters moves elevator 23 to the inside by lifting arm-tie I22 simultaneously, and it is mobile to the inside with lifting arm-tie II18 that the support 6 of floating drives lifting arm-tie IV21.Pincers 5, supporting member 7 and the braking rail 3 of will floating under the effect on elevator 23, supporting member 7 inclined-planes lifted 25mm.Electrical motor cuts off the power supply under the control of travel switch, and the anti-device that slips is in braking mode, finishes braking.When vehicle enter anti-slip during device since the distance of two braking rail, 3 lateral surfaces greater than the right inner distance of vehicle wheel, force the pincers 5 that float to rotate, floating and clamping under the effect of 5 mechanical levers around main shaft 4, the stock rail 2 that will float lifts, transmission by power, make 3 pairs of vehicle wheels of braking rail produce the side pressure friction force to the inboard, form resisting moment, the size of its resisting moment is to be determined by the weight that is braked vehicle, thereby obtains the purpose that vehicle anti-skid stops.
(2) alleviate: when anti-slide device is received the alleviation order, the rotation of motor anticlockwise direction.Driving and reversing mechanism 17 makes advance and retreat plate 12 along the outwards motion of track alignment symmetry, advance and retreat plate 12 drives two hinges 13,14 and rotates around hinge axis 15,16, the unsteady support 6 of pulling simultaneously, unsteady pincers 5 and supporting member 7 move to the inside, reach and alleviate the position, the lifting arm-tie III20 of supporting member 7 drive lifters promotes elevator 23 laterally by lifting arm-tie I22 simultaneously, and the support 6 of floating drives lifting arm-tie IV21 lifting arm-tie II18 is promoted laterally.Pincers 5, supporting member 7 and the braking rail 3 of will floating under the effect of elevator 23, supporting member 7 inclined-planes and gravity falls 25mm.Limit for height≤25mm of this moment, electrical motor cuts off the power supply under the control of travel switch, and the anti-device that slips is in relieved state, finishes alleviation.
When train and vehicle will pass through to hair line, make the anti-device that slips be in relieved state by the control desk push button control, under the effect of lifter, will prevent slipping device decline 25mm, the distance that makes the braking rail friction face is 1290mm (less than a wheel to inboard square 1353mm).This moment, the anti-the highest gauge of device of slipping was no more than stock rail rail level 25mm (track clearance), did not influence passing through of locomotive and other vehicle.When vehicle is parked in when needing anti-the slide on the hair line, control button makes the anti-device that slips be converted to braking mode by relieved state, and support protruding this moment, and the distance that makes the braking rail friction face is 1363mm.Simultaneously lift 25mm by will float pincers, braking rail of lifter, affact the wheel inboard, braking rail and wheel produce friction force, stop wheel, reach the purpose of anti-slide.
In actual the use, stopping device can adopt two or three to be installed in series as required, and every interstation distance can be decided according to a station particular case, and its transmission device is installed in the stopping device middle part, and control box is installed in the stopping device outside, is convenient to debugging and heap and repaiies.
