Structure ensure that the intensity of entire braking body frame 1, and ensure that the toughness of braking body frame 1；Integrated steel construction also ensures vehicle out of control
The promotion point of lower end braking brake pad 2 can be transmitted to safely to the impact force of braking body frame 1.
Braking body frame 1 is the main stressed member of car lug, by braking the buffer plate 14 of 1 front end of body frame to vehicle out of control
The consumption of part kinetic energy brakes body frame 1 by its steel construction and remaining vehicle inertia impulse force is transferred to braking brake pad 2.
The section of the side plate box frame construction and chassis box frame construction of braking body frame 1 is isosceles triangle, and triangle has steady
Solidity, therefore the structural stability for braking body frame 1 is strong, when errant vehicle and braking body frame 1 collide, is not easy to damage.
11 front end of mainboard box structure of braking body frame 1 is provided with buffer plate 14, and buffer plate 14 and braking body frame 1 are logical
It crosses and is bolted.Buffer plate 14 reaches 65-75A, impact resistance using oneself the third rubber of black ternary, the shore hardness of this rubber
It is good, it can effectively avoid hitch from causing the damage of hitch, vehicle frame and car lug in the moment contacted with car lug.Current state iron
Iron hook height be 880mm, therefore buffer plate center and 4 distance 880mm of rail.
Braking body frame 1 is laid flat on rail 4, is connect using anti-creep clamping plate 15 with rail 4.The enlarged diagram of anti-creep clamping plate 15
As shown in Figure 4.Anti-creep clamping plate and braking body frame 1 by high-intensitive bolt connect anti-creep clamping plate 15 and rail 4 have it is certain between
Gap, therefore, braking body frame 1 can on rail 4 parallel slip, when errant vehicle hit braking body frame 1 on buffer plate 14,
Braking body frame 1 is hit lift, and anti-creep clamping plate 15 is stuck on rail 4, inhibits to lift on braking body frame 1, braking body frame 1 is put down backward
Line slip pushes braking brake pad 2 to move forward.
Fig. 5 is the schematic diagram of braking brake pad 2.Braking brake pad 2 is connect with rail 4, in the present embodiment, braking brake pad
2 include clamping plate 21, drag friction item 22 and bolt pair 23, and clamping plate 21 is symmetrically disposed on drag friction two sides, braking brake pad 2
Lower end is connect by bolt pair 23 with rail 4.Bolt pair 23 includes hexagon-headed bolt and adjusting nut, hexagon-headed bolt and clamping plate
Setting locking backing plate 24, is arranged double-deck railroad spring washer 25 between 21 between adjusting nut and clamping plate 21, locks backing plate 24 and bilayer
Railway spring washer 25, which plays the role of reinforcing clamping plate 21 and drag friction item 22, to be connected.
In external force collision brake friction block 2, the drag friction item pushes rail 4, and drag friction item 22 and rail 4 produce
Raw frictional force, causes to brake.In a kind of embodiment of the application, braking brake pad 2 is suitble to a variety of rail types, such as in master
Want 60kg/m, 50kg/m shaped steel rail being laid on main line；Braking brake pad 2 can compensate for the abrasion of various old rails, can be repeatedly
It installs and uses, without replacement；The brake force of each pair of braking brake pad 2 is 50KN in the present embodiment, and braking brake pad 2 can quantify
Braking friction is controlled, the quantity of braking brake pad 2 and arrangement position will be determined according to the actual condition of errant vehicle.Using special
The detection device of industry can quantitatively carry out brake force test to braking brake pad 2, guarantee the braking brake pad 2 in the case where setting operating condition
Quantity and arrangement position, so that sliding car lug is more reasonable in the quantitative design of braking brake pad 2.
As shown in Figure 1, the setting of steel construction guard 3 is after braking body frame 1 and braking brake pad 2, it is most close to rail 4
Head, errant vehicle speed beyond sliding car lug design keep off a car ability when, one of protective barrier can be increased.
The working principle of sliding car lug provided by the present application is: when errant vehicle knocks the braking body frame 1 of car lug
When, braking body frame 1 slides backward immediately, and generates brake force to errant vehicle, braking body frame 1 slide after a distance respectively and
It is arranged in subsequent braking brake pad 2 to be in contact, up to all braking brake pads 2 while cooperative brake body frame 1 is to errant vehicle
Carry out pressure stop.I.e. inertia impact → impact head (rubber buffer) of errant vehicle → braking body frame 1 (bottom friction braking,
Steel construction resilient) → braking brake pad 2 (friction catch) → errant vehicle stop.
To ensure that sliding car lug has 10 years or more service life, in embodiment provided herein, use
Chemical substance to car lug surface carry out preservative treatment: shot blasting on surface, galvanizing by dipping, one layer of 842 epoxy micaceous iron oxide rustproof paint and
The overall thickness of two layers of chlorinated rubber finish, coating reaches 230-270um.
The installation length of sliding car lug will be depending on the operating condition of errant vehicle, it is generally the case that sliding to keep off a car
Device occupies the length of rail 4 between 8000-12500 meters.
Above embodiments are only to illustrate the technical solution of the utility model and non-limiting, reference only to preferred embodiment pair
The utility model is described in detail.Those skilled in the art should understand that can be to the technology of the utility model
Scheme is modified or equivalent replacement, without departing from the spirit and scope of the technical scheme of the present invention, should all cover in this reality
With novel scope of the claims.
