Description
Technical field
The utility model relates to the rolling stock parking anti-slip device.
Background technology
At present stopping device has hydraulic pressure, machinery, form such as electronic.The hydraulic parking device is owing to poor reliability such as hydraulic efficiency pressure system leakage of oil, interior relaxations, and opening time is long, and particularly seasonal temperature changes to the influence of equipment hydraulic part greatly.Electronic stopping device adopts motor braking, poor synchronization, power consumption height.And the mechanical parking device adopts mechanical drive, makes the braking rail braking, have simple in structure, fault rate is low, reliable transmission.And at present the mechanical parking device has quick mechanical lifting stopping device, and this stopping device braking rail glancing impact rises, and falls the location that is mainly used in hair line, departure track, has train to pass through, and device structure complexity, equipment manufacturing cost height during alleviation.
Summary of the invention
It is a kind of not with jacking system, simple in structure, cheap rolling stock parking anti-slip device that the purpose of this utility model is to provide.
The utility model provides a kind of mechanical parking anti-skid device, mainly comprise motor, retarder, brake control lever unit and braking rail, motor makes brake control lever unit operation braking rail by retarder, it is characterized in that: the brake control lever unit is made up of bottom girder 11, driving screw 14, nut 13, connecting rod 4, left support arm 1, right support arm 5, bottom girder 11 usefulness rail clips 8 are fixed on the rail 12, driving screw 14 is fixed on the centre of bottom girder 11, nut 13 moves on driving screw 14, and nut 13 links to each other with right support arm 5 with left support arm 1 by connecting rod 4 respectively.Motor drives driving screw 14 rotations by retarder, associated nut 13 produces displacement, promote or spur left support arm 1 and the 5 overhanging or withdrawals of right support arm by connecting rod 4, make braking rail 6 outer opening implement to slip to car brakeing is anti-, perhaps return, leave inboard enforcement of wheel and alleviate, to reach the purpose that prevents the wheel runaway
The mechanical parking anti-skid device that the utility model provides, its left support arm 1 or right support arm have spring 10 for 2 li, to increase braking force.
The mechanical parking anti-skid device that the utility model provides has limit switch on its driving screw 14, disconnects motor when nut reaches limit switch, so that accurately control the stroke of nut, thus the stroke of accurate control brake rail.
The mechanical parking anti-skid device that the utility model provides, its driving screw 14 is left-right symmetric screw rods, nut 13 and connecting rod 4 are two covers of symmetry, have both made left support arm 1 and right support arm 5 stressed even, increase conservative factor again.
The mechanical parking anti-skid device that the utility model provides, its rail clip 8 are to be fastened on the rail 12 with bolt 7, not only convenient but also safety.
The advantage of the mechanical parking anti-skid device that the utility model provides is: transmission process is to adopt screw rod to replace reductor to make braking rail stretch out or withdraw, and conserve energy is simple in structure, cheap, good braking effect.

The specific embodiment
Embodiment 1
The mechanical parking anti-skid device that the utility model provides is made up of motor, retarder, several brake control lever unit and braking rail.
The structure of brake control lever unit as illustrated in fig. 1 and 2, the bottom girder 11 of each brake control lever unit is fixed on the rail 12 by rail clip 8 and bolt 7, nut 13 is installed on the left-right symmetric screw rod 14, nut 13 usefulness pitman pins 2 link to each other with right support arm 5 with left support arm 1 respectively by connecting rod 4, braking rail 6 usefulness bolts 9 in both sides are connected on left support arm 1 and the right support arm 5 with bolt 9 respectively, spring 10 is installed on the left support arm 1, and left support arm 1 and right support arm 5 are installed on bottom girder 11 supporting plates 16 by round pin 15.
Each left and right support arm 1 links to each other with both sides braking rail 12 with 5 simultaneously, links to each other with transmission shaft between each left-right symmetric screw mandrel 14 and links to each other with motor with retarder by transmission shaft.
When vehicle is implemented glancing impact, 14 right rotations of left-right symmetric screw rod, nut 13 is drawn close, and outwards moves by connecting rod 4 left support arms 1 of promotion and right support arm 5, and both sides braking rail 6 moves laterally simultaneously, and be close to vehicle wheel to the inboard, and compression spring 10, produce braking force, put in place until travel switch 3, left-right symmetric screw rod 14 stops operating, and prevents the rolling stock runaway.
When train involves, 14 anticlockwises of left-right symmetric screw rod, nut 13 moves respectively laterally, and it is mobile to the inside by connecting rod 4 left support arms 1 of drive and right support arm 5, both sides braking rail 6 moves inward, and leaves wheel to the inboard, leaves wheel until both sides braking rail 6, travel switch 3 puts in place, and left-right symmetric screw rod 14 stops operating.
Vehicle is implemented glancing impact, both sides braking rail 6 is close to the wheel inboard, but vehicle wheel traveling in operational process is a serpentine path, therefore propping up an arm assembly 1 and a right arm assembly 5 and round pin 18 junctions on a left side is slotted hole, both sides braking rail 6 moves freely about can be within the specific limits, satisfies the needs of wheel hunting.
