Specific implementation mode
In the following with reference to the drawings and specific embodiments, the utility model is further described.
Embodiment 1：As shown in Figs. 1-5, a kind of bend integrated planar bearing-type rail, including rail 1, backing plate 2, reinforcing bar are mixed
Solidifying soil sleeper 3, railway spike 4, plane bearing 5, anti-creeping strut 6, railway roadbed 7, train wheel 8, rail cavity 9, bearing fixed frame 10, rail cavity
9 are located at the side of 1 racetrack portion of rail contact 8 wheel rim of train wheel, and bearing fixed frame 10, plane axis are fixed in rail cavity 9
It holds 5 to be mounted on inside bearing fixed frame 10, outside is contacted with 8 wheel rim of train wheel, and 10 upper and lower ends of bearing fixed frame are all provided with
There is a bearing mounting hole, plane bearing 5 includes mediate cylindrical and is connected to mediate cylindrical upper and lower side and has round and smooth lead angle,
Protruding shaft is equipped on the outside of round and smooth lead angle, plane bearing 5 may be rotatably mounted at about 10 bearing fixed frame by the protruding shaft of upper and lower ends
In the mounting hole at both ends, the rotation direction of plane bearing 5 is that This train is bound for XXX, and spacing side by side installation is more in a rail cavity 9
A plane bearing 5.
Further, the radius of the 5 round and smooth lead angle of plane bearing is 1mm, and angle is 45 °.
Further, the plane bearing 5 is using traditional structure of steel product.
Further, 10 both sides of bearing fixed frame are equipped with buckle, and the corresponding position of rail cavity 9 is equipped with card slot, buckle
It is equipped with spring leaf with the junction of card slot, spring leaf can be such that buckle is firmly installed in card slot, and play vibration proof.
In the utility model, rail cavity 9, bearing fixed frame 10, rail 1, backing plate 2, reinforced concrete sleeper 3, railway spike 4,
Anti-creeping strut 6, train wheel 8, is existing rail composition part at railway roadbed 7, and installation and connection relation between them are no longer specifically
It is bright.
Plane bearing is a kind of device cheap, simple in structure, stability is high, anti-pressure ability is strong, the utility model
Positive effect is also obtained using the rotary buffer road rail that plane bearing principle is made, this guardrail effectively prevents vehicle
The rollover phenomenon after guardrail is bumped against, sliding friction is converted to rolling friction, vehicle is driven to be moved along, reduces accident wound
Die rate.
Plane bearing 5 is common iron structure in the utility model, and every 1 meter is individual one section, on the rail head of rail 1
The rail cavity 9 opened is also 1 meter long, plane bearing 5 can just be integrated in the inside, can be directly by plane bearing 5 in repair
It removes, is replaced, polished or added lubricating oil.Rail cavity 9 is opened on the rail head of rail 1, carries out structural simulation, it is ensured that fluting
The strength and stiffness of steel-rail structure are not interfered with later, and plane bearing 5 is only integrated in the corner of rail 1, is ensureing work(in this way
Accomplish that cost is minimum in the case of capable of realizing, and plane bearing 5 is inherently cheap, common iron structure, rigidity, intensity are resistance to
With, it is not necessary to it replaces at any time.
The operation principle of the utility model is：Open a rail in the side that train wheel is contacted in 1 racetrack portion rail head of rail
Road chamber 9, bearing fixed frame 10 fix plane bearing 5, and plane bearing 5 is integrated in rail cavity 9, have using plane bearing 5
Train is oriented to the direction of train driving, is the principle of rolling friction after contact furthermore with plane bearing 5 by the effect of guiding
Reduce the loss to train wheel and rail.Become rolling friction from sliding friction when excessively curved so that wheel rim
Climbing the critical speed of rail becomes higher.Railway described in the utility model and existing railway are excessively curved under same uniform velocity, this reality
With novel safety higher, the utility model is related to this rail also can be excessively curved with higher speed, other conditions not
The operational efficiency that train is improved in the case of change, the economic value brought are also just very huge.
The theoretical foundation of the utility model is：From physically saying, train hit rail 1 described in the utility model when
Time will produce pressure, resistance, elastic force and frictional force：Train can be driven to enter rapidly in the rotation of the moment plane bearing 5 of shock
Firing angle degree is reduced, to reduce pressure between the two；Plane bearing 5 reduces the elastic force of vehicle, can buffer the speed of train
Degree；The longitudinal force of train becomes force of rolling friction simultaneously, and resistance becomes smaller so that the collision time of vehicle and guardrail shortens, and keeps away
Exempt from that second accident occurs.
Assuming that the weight of train be M, turning radius R, train curve speed be V, centrifugal force F,
, obtain
,
It can be seen that V reduces therewith when F reduces, the centrifugal force F of the utility model F smallers compared with the prior art, so
It can obtain the excessively curved speed higher of rail described in the utility model under identical centrifugal force F.
Assuming that the excessively curved speed of rail described in the utility model is 0.64 times of the excessively curved speed of existing rail.
When the centrifugal force of rail described in the utility model is identical with the centrifugal force of existing rail：
。
The excessively curved speed of rail described in the utility model is original 1.25 times, is not changing too many structure, Jin Jin
1 side of rail is slotted, and 25% speed is improved in the case of integrated planar bearing 5.
Online plane bearing 5 of finding is designed to that 1 meter is individual such structure according to described in the utility model,
Price is each in 10-12 members, if price is lower if a large amount of buyings, if it is action by government, can directly do factory's making, price
Lower, by taking time train of Kunming to Chengdu K854 as an example, mileage is 1133 kilometers, it is assumed that bend is the 20% of railway overall length, bend
Length is at 226.6 kilometers, and plane bearing 5 is calculated according to each 10 yuan needs 226.6 ten thousand yuan, and so low price can improve 25%
Speed, meaning is huge.
Above in association with attached drawing, the specific embodiments of the present invention are described in detail, but the utility model is not
It is limited to the above embodiment, within the knowledge of a person skilled in the art, this practicality can also be not being departed from
Various changes can be made under the premise of novel thought design and objective.
