The specific embodiment
Referring to Fig. 1, the utility model is by external track block 1,23, pipe collar adapter plate 2,29, pipe collar 3,28, alleviate oil pipe 4, internal track block 5,22, secondary bearing pin 6,20, connecting rod 7,19, stub axle 8,21, braking rail 9,25, first supporting base 10, oil cylinder 11, brake pipe 12, second supporting base, 13 compositions such as grade, wherein, external track block 1,23 and internal track block 5,22 by bolt 14,24 are fixed on circuit stock rail 17, on 18, simultaneously, be arranged on internal track block 5, interior bayonet socket 15 on 22,26 and be arranged on external track block 1, outer bayonet socket 16 on 23,27 cooperatively interact blocks stock rail 17 respectively, thereby 18 inboard base and base, outside chucking stock rail 17,18; Captive joint with first supporting base 10 with internal track block 5 with stub axle 8 by secondary bearing pin 6 respectively in connecting rod 7 two ends on the left side; The connecting rod 19 on the right is captiveed joint with second supporting base 13 with internal track block 22 with stub axle 21 by secondary bearing pin 20 respectively; Captive joint with first supporting base 10, second supporting base 13 in oil cylinder 11 two ends; Braking rail 9,25 is separately fixed on first supporting base 10 and second supporting base 13 by bolt, alleviates oil pipe 4 and brake pipe 12 and is fixed on the internal track block 5,22 by pipe collar adapter plate 2,29 and pipe collar 3,28 respectively.
Lifting mode of the present utility model can be realized braking and alleviate two kinds of operating modes that to the static anti-device actuating unit that slips of hair line its implementation procedure is as follows:
(1) implementation procedure of damped condition
When brake pipe 12 comes hydraulic oil, hydraulic oil enters the brake chamber of oil cylinder 11, the piston rod that hydraulic oil promotes oil cylinder 11 outwards moves, the connecting rod mechanism of being made up of connecting rod 7,19, first supporting base 10, second supporting base 13 and oil cylinder 11 is rotated around the secondary bearing pin 6,20 of internal track block 5,22 and connecting rod 7,19, the braking rail 9,25 at two ends is risen, distance between braking rail 9,25 both ends of the surface is greater than the inboard distance of wheel, braking rail 9,25 increases apart from the height of rail level simultaneously, and the retarder actuating unit is in damped condition.Fashionable as the vehicle slide, braking rail 9,25 applies a friction brake force for the wheel inboard, makes wheel produce lock torque, reaches the purpose of car brakeing.At this moment, oil cylinder 11 is alleviated the hydraulic oil flow in chamber to alleviating in the oil pipe 4.
(2) implementation procedure of alleviation operating mode
When alleviation oil pipe 4 comes hydraulic oil, hydraulic oil enters the alleviation chamber of oil cylinder 11, the piston rod that hydraulic oil promotes oil cylinder 11 moves inward, make by connecting rod 7,19, first supporting base 10, the connecting rod mechanism that second supporting base 13 and oil cylinder 11 are formed is around internal track block 5,22 and connecting rod 7,19 secondary bearing pin 6,20 rotations, make the braking rail 9 at two ends, 25 fall, braking rail 9, distance between 25 both ends of the surface is less than the inboard distance of wheel, while braking rail 9,25 height apart from rail level reduce, the retarder actuating unit is in the alleviation operating mode, the anti-device that slips of a mistake that can guarantee to be open to traffic, at this moment, the hydraulic oil flow of oil cylinder 11 brake chambers is in brake pipe 12.
In sum, of the present utility modelly solved institute in the background technology to the static anti-slip device of hair line executing agency The limit for height of executing agency remains unchanged substantially when the braking of stating and alleviation, during alleviation, to passing through train sometimes The possibility that generation is transfinited affects traffic safety; It is lower to brake simultaneously limit for height, Brake Energy height, anti-slip energy The technical problem that power seems not enough, have simple in structure, flexible movements are reliable, and are easy for installation, safeguard simple Etc. characteristics, be a kind of desirable static anti-slip equipment of hair line that arrives.
