Using the technical solution of the present embodiment, mobile device 10 and clamping device 20 are set in anti-derail unit, passed through
Clamping device 20 can clamp track 40, can be by clamping device 20 and the track being clamped 40 by mobile device 10
It is moved to the position that track 40 is contacted with wheel and is kept in contact track 40 and wheel, it in this way can be to avoid wheel and track 40
It is detached from.Therefore, technical solution through this embodiment is able to solve the problem of wheel in the prior art is easily separated from track.
In the present embodiment, clamping device 20 includes：Clamping part, clamping part are used for gripper rail；First driving portion 21, if
It sets in mobile device 10, the first driving portion 21 is drivingly connected with clamping part, and the first driving portion 21 is for driving clamping part mobile.
Clamping part can be driven mobile by the first driving portion 21 in this way, thus clamping or evacuation track.
In the present embodiment, clamping part and mobile device 10 are hinged, the first driving portion 21 clamping part can be driven to rotate with
Clamping or evacuation track.Movement of the clamping part in mobile device 10 can be easy to implement by hinged mode.
Further, one end of the first driving portion 21 and mobile device 10 are hinged, the other end and folder of the first driving portion 21
Hold that portion is hinged, the length of the first driving portion 21 is scalable to drive clamping part to rotate.It in this way can stretching by the first driving portion 21
Contracting is to drive clamping part to rotate.In the present embodiment, hydraulic cylinder can be set by the first driving portion 21, so simultaneously convenient for control
And there are enough driving forces, high reliablity.
Specifically, clamping part includes：Clamp arm 22 is connect with the first driving portion 21；Idler wheel 23, is rotatably arranged in clamp arm
On 22, it is mobile to clamp or avoid track by idler wheel 23 that clamp arm 22 is able to drive idler wheel 23.Pass through setting clamp arm 22 and idler wheel
23, after idler wheel 23 and rail contact, idler wheel 23 can reduce frictional force along orbit rotation in this way.
In the present embodiment, clamp arm 22 and mobile device 10 are hinged, and clamping part further includes：Shaft 24, can be rotatably set

It is detached from.Therefore, technical solution through this embodiment is able to solve the wheel in the prior art with quarrel vehicle and is easily separated from track
Problem.
By taking 200 types are with quarrel vehicle as an example, 200 types have the characteristics that wheelbase is short, narrow space with quarrel vehicle, so to derailing dress
Set the size of each part, model there are strict requirements.Anti-derail unit can be added in front of wheel in pilot and middle plough guard rail
Between cover, distance is 200mm between the two.In the case where being limited by the spacing, in order to not influence the normal of anti-derail unit
Enhancing action, so single 20 plane of structure total length of clamping device determines that the items of clamping device 20 refer to no more than 150mm with this
Mark.
Rigid member material can be set to GCr15, i.e. high-carbon-chromium bearing steel in anti-derail unit.According to engineering material knowledge
It is known that：GCr15 can guarantee that steel has high hardness and strength and keeps the harden ability of material lower.As it can be seen that high carbon chromium
Bearing steel has high hardness and high elastic limit and high contact fatigue strength and toughness appropriate, and has centainly resistance to
Corrosive power.
200 with quarrel vehicle self weight be 28 tons, vehicle body wheelbase be 5.5m.The standard rail and standard sleeper total weight of 5.5m are pressed
Can be calculated according to national standard is 3 tons, so it is 31 tons that gross mass, which can be calculated,.This can be in front of four wheels with quarrel vehicle
Anti-derail unit is installed respectively, so the theoretical weight that each hoist point is subject to thus can be calculated.200 types install vehicle with quarrel vehicle
The crossbeam of wheel to rail level distance be 960mm.Consideration proposes rail parameter and operation finishes the safe distance to return the vehicle to the garage and knock off, can be by the second driving
The stroke in portion 12 is set as 155mm.
It can prevent from the generation of failure being reduced, so as to the company of realization with quarrel vehicle derailing according to the technical solution of the present invention
Continuous operation, provides production efficiency.Moreover, because will not derail with quarrel vehicle, it can make to match quarrel vehicle and other equipment are realized and joined
Cooperate industry, for example, the operation after screen scarifier is arranged with quarrel vehicle in 200 types.Anti-derail unit adds 200 types that balance with quarrel vehicle
Using the Mechanical Form in the plough operation process of side, solves the problems, such as that 200 types easily derail with quarrel vehicle construction, broken traditional clear
Grouping formulation is sieved, operation after screen scarifier can be directly grouped in.Tamping car tamping quality is improved, construction cost has been saved,
Operating efficiency is effectively increased, has won valuable time for the operation of large-scale maintenance machinery.
