Example 1
As shown in fig. 1, the anti-sliding structure of the rail electric vehicle is composed of a hook rod structure 1, a hook structure 2, a hook limiting hole structure 3, a hydraulic telescopic rod 4, a limiting bolt 5, a hook rod bearing piece 7, a telescopic rod bearing piece 8 and a connecting bridge structure 6. One end of the coupler structure 2 is a connecting end and is used for being hinged with the coupler rod structure 1, and the other end of the coupler structure is a coupler opening end and is used for hooking a sleeper.
The coupler link holds a piece 7 and sets up in the first articulated support of conduct of electric motor car locomotive front end, and coupler link structure 1 one end holds a piece 7 with the coupler link and articulates, and articulated department is first pin joint, and the other end is articulated with coupler structure 2's link, and articulated department is the second pin joint. The coupler structure 2 has its coupler mouth facing downwards.
The telescopic link holds carrier 8 and fixes at the locomotive, and 4 one ends of hydraulic telescoping rod hold carrier 8 with the telescopic link and articulate, and the other end and 1 hinge of hook rod structure, articulated department are the third hinge point, and the third hinge point is located between first pin joint and the second pin joint. The hook rod structure 1 is further provided with a limiting bolt 5 which is located between the first hinge point and the third hinge point.
The hook rod structure 1 can swing by taking the first hinge point as a circle center under the action of the hydraulic telescopic rod 4. The coupler structure 2 can swing by taking the second hinge point as a circle center.
The car coupler limiting hole structure 3 is fixedly arranged on the car coupler structure 2. The two are welded into an integral structure, the car coupler limiting hole structure 3 is provided with an arc-shaped hole channel, the arc-shaped track of the car coupler limiting hole structure uses a second hinged point as a circle center, the limiting bolt 5 is positioned in the arc-shaped hole, and the car coupler structure 2 is not influenced by the limiting bolt 5 when the electric car moves forward and swings up and down due to dead weight.
Two groups of the structure can be arranged at the head of the electric vehicle, and the two hook rod structures 1 are connected through the connecting bridge structure 6.
In the advancing process of the electric vehicle, the hook structure 2 can be lifted upwards due to acting force after colliding with a sleeper and then falls down by self weight after passing through the sleeper as shown in figure 3. When the car slipping trend occurs, the car coupler structure 2 directly hooks the sleepers, the car coupler limiting structure 3 plays a role, the car slipping distance of the electric car does not exceed the distance between two sleepers, the initial speed of the electric car slipping is small, the momentum is small, and the electric car slipping can be controlled in time and easily. The stop cock 5 fixed on the coupler rod structure 1 is positioned on the reserved arc-shaped hole of the coupler limiting structure 3, the diameter of the stop cock is slightly smaller than the width of the arc-shaped hole, the swing of the coupler limiting structure 3 and the coupler structure 2 is not hindered, the swing amplitude of the coupler structure is limited at the same time, and the design purpose is achieved.
When the tunnel electric vehicle has a vehicle sliding tendency or slides for a short distance, a hook opening of a vehicle hook structure 2 of the device hooks a sleeper, a vehicle hook limiting structure 3 moves along with the sleeper until the limiting bolt 5 prevents the sleeper from continuing to move, as shown in figure 4, the electric vehicle is subjected to acting force opposite to the moving direction of the electric vehicle, and the tunnel electric vehicle is made to be static by the acting force, so that the tunnel electric vehicle is prevented from sliding. After the sliding fault is removed or control measures are taken, the switch in the operating room controls the hydraulic telescopic rod 4 to lift the hook rod structure 1, the hook structure can be separated from the sleeper, then the hydraulic telescopic rod 4 is controlled to return to a normal position, and the electric vehicle enters the openable state again.
The hook mouth design of coupler structure 2 matches with the sleeper shape, can support the sleeper with the angle of more laminating, reaches the better effect of preventing swift current car. The coupler structure 2 moves on the sleeper by means of the power and the dead weight of the electric vehicle in the normal running process of the electric vehicle, and cannot damage the sleeper. When a car slipping event occurs, the electric car moves reversely, the car coupler can automatically hook the sleeper, the effect of preventing car slipping without personnel operation is achieved, the influence of human factors is reduced, the influence of car slipping accidents is reduced to the maximum extent, the safety of personnel and property in the tunnel is guaranteed, and the safety is more reliable.
