Working principle
The application stopping wheel and prevention for runaway top is made of housing assembly 2 and sliding oil cylinder sub-assembly 1, and two parts pass through under shell
Side only rushes structure 3 and links together.It is that 2mm is mono- that check valve adjusting screw installing blind bottom end, which is machined with diameter, on piston rod 4
To flowing hole, the return interval on unidirectional flowing hole and the cooperation increase of backhaul valve plate 8 top.The setting of 4 inner part drilling spring of piston rod is blind
Hole is mounted directly pressure valve outer spring 5 and pressure valve inner spring 6 without adjusting pressure valve opening pressure, prevents the position from event occurs
Barrier and worker's maloperation.And stairstepping cylindrical bar is processed into bottom, is pierced by by housing assembly 2, plugs R pin and is stopped
Punching.Columnar housing bottom processes a cylindrical hole, is used to drainage exhaust, and structure is simple.The shell on the stopping wheel and prevention for runaway top
Sub-assembly 2 is symmetrically fixed on the outside of two rail by two bolts.The top only taking turns to vehicle is realized by hydraulic principle
Anti-slip function, it may be assumed that when the wheel of standing vehicle is in contact with stopping wheel and prevention for runaway top sliding oil cylinder 14, sliding oil cylinder 14 is depressed one
The volume of Duan Hangcheng, epicoele reduce, and nitrogen is forced to compress, and upper cavity pressure increases, and sliding oil cylinder 14 produces vertically wheel
Counter-force and level braking component prevent wheel rolling.Due to being equipped with sealing dress between 14 inner wall of piston rod 4 and sliding oil cylinder
It sets, sliding oil cylinder epicoele is enabled to keep high pressure conditions for a long time, so stopping wheel and prevention for runaway top maintains for a long time vehicle
Greater level brakes component, plays the role of to vehicle stopping wheel and prevention for runaway.It is left after sliding oil cylinder 14 is depressed into minimum point by wheel
When, gone up upwards in sliding oil cylinder 14 due to the expansion by compressed nitrogen, cavity of resorption oil liquid passes through unidirectional on piston rod 4
Valve adjusting screw 11 returns to epicoele.Due to the throttling action of 11 valve port of check valve adjusting screw, make the oil liquid of cavity of resorption can only be with one
Fixed flow velocity returns to epicoele, therefore sliding oil cylinder 14 can only be gone up with slower speed.
It (such as involves, dispatch a car) when train passes through stopping wheel and prevention for runaway top with higher speed, the slow characteristic of the top backhaul makes
Sliding oil cylinder 14 can only be contacted in lower position with wheel, play or do not rise braking action less to vehicle.The speed of vehicle is higher,
Wheelbase is shorter, and this effect is just more obvious.So stopping wheel and prevention for runaway top had not only met the requirement of stopping wheel and prevention for runaway, but also reduce train height
The impact of wheel and stopping wheel and prevention for runaway top when speed passes through, reduces unnecessary abrasion, improves the safety of transport production.
It is about the application retarding braking, stopping wheel and prevention for runaway and backhaul working condition explanation below
1. retarding braking is shown in Fig. 6
When runaway vehicle is by only wheel top, wheel forces only wheel top sliding oil cylinder pressure, the volume reduction of epicoele
The nitrogen of epicoele sharply compresses, and increases pressure rapidly, and when pressure is more than pressure valve opening pressure, pressure valve is opened, oil liquid
Cavity of resorption is flowed to by pressure valve with higher pressure, sliding oil cylinder 14 is made to generate biggish system to wheel while slide downward
Power.By law of physics it is found that having done function to wheel by the sliding oil cylinder under pressure wheel, therefore deceleration is risen to vehicle and has been made
With.When the function that only wheel top is done is equal with the kinetic energy of vehicle, vehicle is just braked parking.
2. stopping wheel and prevention for runaway
When the wheel of standing vehicle with only wheel top sliding oil cylinder is in contact when, sliding oil cylinder 14 is depressed a trip,
The volume of epicoele reduces, and nitrogen is forced to compress, and upper cavity pressure increases, and sliding oil cylinder 14 produces vertical reaction and level to wheel
Component is braked, wheel rolling is prevented.Due to being equipped with sealing device between piston and sliding oil cylinder inner wall, so that sliding oil cylinder 14
Epicoele can keep high pressure conditions for a long time, so only wheel top maintains prolonged greater level braking component to vehicle, rise
It has arrived and vehicle stopping wheel and prevention for runaway has been acted on.
3. seeing Fig. 7 when backhaul
When being left after sliding oil cylinder 14 is depressed into minimum point by wheel, due to by the expansion of compressed nitrogen in sliding oil cylinder 14
It acts on and gos up upwards, cavity of resorption oil liquid returns to epicoele by the check valve adjusting screw 11 on piston rod 4.Due to backhaul valve plate 8
And the throttling action of piston rod flowing hole, make the oil liquid of cavity of resorption that can only return to epicoele, therefore sliding oil cylinder 14 with certain flow velocity
It can only be gone up with slower speed.
It (such as involves, dispatch a car) when train is pushed up with higher speed by only taking turns, only the slow characteristic of wheel top backhaul makes it
Sliding oil cylinder can only be contacted in lower position with wheel, play or do not rise braking action less to vehicle.The speed of vehicle is higher, axis
Away from shorter, this effect is just more obvious.So only wheel top had not only met the requirement of stopping wheel and prevention for runaway, but also reduces train high speed and pass through
When wheel with only wheel top impact, reduce unnecessary abrasion, improve the safety of transport production.
