Description

One-way self-lock deceleration top

The utility model belongs to the improvement of railway hump marshalling yard skating vehicle with unidirectional deceleration top, is applicable to hump side merchant to involve the departure track that frequent and contrary rolling direction is driven.

Acting when humping of cars with vehicle is anti-when leading, as long as vehicle reaches deceleration top critical speed, is all braked to vehicle in the top of slowing down, the outside at present the gravitation marshalling yard equipment that is used for the rolling braking has.This merit is a useful work when humping of cars, and this merit is an idle work in that vehicle is anti-when leading, waste locomotive energy, controlled when withstanding on humping of cars personnel selection go to control jacking and rise, vehicle is implemented acting slows down; In that vehicle is anti-when leading, vehicle is inhaled the position earlier with under the controlled roof pressure with electromagnetic valve.This equipment is active equipment, cost height, wiring complexity.Unidirectional deceleration plays deceleration effort when withstanding on humping of cars, in that vehicle is anti-when leading, unidirectional deceleration top is overwhelmed by vehicle, treat after the vehicle that unidirectional deceleration leans an oil cylinder and slowly returns to original position, this equipment is owing to overwhelmed by wheel, therefore exist unidirectional deceleration top and outwards rolled over crowded phenomenon by wheel, influence service life, bring very big difficulty, increase frequency of maintenance to maintenance.

The purpose of this utility model provides a kind of saving locomotive energy, it is low to declare to reliable, working stability, cost, when the rolling of vehicle front, play the effect of deceleration top, play the effect of unidirectional deceleration top when leading in that vehicle is counter, just to the anti-unidirectional self-lock that can not lead deceleration effort of the vehicle top of slowing down.

The technical solution of the utility model is achieved in that the unidirectional self-lock top of slowing down forms by declaring to device, the soft transmission shaft of metal and deceleration with lock top; Declare to device and form by shell, guide pillar, pull back spring and opening shuttle with 90 ° of conical surfaces.Opening shuttle is by adjusting blind nut, balance spring, forming with sliding iron, the bearing pin of 90 ° of spigot surfaces.Top with lock is made up of dead bolt, snap and locking closure; Declaring in device, pass pull back spring with the guide pillar of 90 ° of conical surfaces and contact with opening shuttle.In the opening shuttle, balance spring contacts with sliding iron phase, and sliding iron links to each other with the soft transmission shaft of metal, and in the top with lock, dead bolt is between snap and locking closure.

Below in conjunction with accompanying drawing the utility model is described in detail as follows:

Fig. 1 is unidirectional self-lock deceleration roof construction figure.

Fig. 2 is for declaring to the device cutaway view.

Fig. 3 is the opening shuttle cutaway view.

Fig. 4 is the self-locking mechanism cutaway view on unidirectional deceleration top.

One-way self-lock deceleration top is made up of direction device 1, metal soft drive shaft 2 and decelerating with lock 3. Direction device 1 is made up of shell 4, guide pillar 5, return spring 6 and opening shuttle 7 with 90 ° of conical surfaces, opening shuttle is by adjusting blind nut 8, balancing spring 9, forming with sliding rail 10, the bearing pin 11 of 90 ° of spigot surfaces, and top 3 with lock is made up of dead bolt 12, snap 13 and locking closure 14.

In direction device 1, pass return spring 6, contact with opening shuttle 7 with the guide pillar 5 of 90 ° of conical surfaces. In the opening shuttle 7, balancing spring 9 contacts with sliding rail 10, and sliding rail 10 links to each other with metal soft drive shaft 2, and in the top 3 with lock, dead bolt 12 is between spring 13 and locking closure 14.

Embodiment:

After the rolling from the hump of disintegration vehicle is got off, wheel is pressed onto earlier to be declared on device 1, the guide pillar of declaring to device 15 is moved down, 90 ° of conical surfaces of guide pillar 5 contact with 90 ° of spigot surfaces of sliding iron 10, this moment, all guide pillars 5 all made sliding iron 10 to contrary rolling direction motion, and the soft transmission shaft 2,2 of pulling metal spurs the dead bolt 12 on deceleration with lock top 3 again, dead bolt 12 breaks away from locking closure 14, and rise on deceleration with lock top 3.Wheel is rotated further, and is pressed onto top 3 with lock, and top with lock is depressed again after skating vehicle is done work, and is pinned by dead bolt 12.Dead bolt 12 is by snap 13 resiliences, and this moment, top 3 with lock was lower than rail level, lost brake action.

When vehicle is anti-when leading, on the top with lock 3 of being pinned by snap 12 after the anti-wheel that leads vehicle is pressed onto earlier and has compressed, vehicle is not subjected to brake action, be pressed onto again then that 90 ° of conical surfaces declaring to device 1 guide pillar 5, guide pillar 5 contacts with 90 ° of conical surfaces of sliding iron 10, all guide pillars 5 all make sliding iron 10 move to the smooth direction of putting at this moment, sliding iron 10 does not spur the soft transmission shaft 2 of metal, top 3 with lock is in by the lock state, and all anti-vehicles that lead are not done work.Guide pillar 5 rises return by pull back spring 6, keeps the playback balance by balance spring 9 after sliding iron 10 slides.The soft transmission shaft 2 of metal is fixing by bearing pin 11.

The utility model compared with prior art has the following advantages:

1, effective to the humping of cars deceleration, can realize the braking of skating vehicle one direction is not braked the anti-vehicle that leads.

2, declare to reliable, working stability, low, the saving locomotive energy of cost.

Claims (1)

1, a kind of unidirectional self-lock top of slowing down is characterized in that: this unidirectional self-lock top of slowing down is formed by declaring to device, the soft transmission shaft of metal and deceleration with lock top; Declare to device by shell, with guide pillar, pull back spring and the opening shuttle composition of 90 ° of conical surfaces; Opening shuttle is by adjusting blind nut, balance spring, forming with sliding iron, the bearing pin of 90 ° of spigot surfaces; Top with lock is made up of dead bolt, snap and locking closure; Declaring in device, pass pull back spring with the guide pillar of 90 conical surfaces and contact with opening shuttle; In the opening shuttle, balance spring contacts with sliding iron phase, and sliding iron links to each other with the soft transmission shaft of metal; In the top with lock, dead bolt is between snap and locking closure.
