The purpose of this utility model is to provide a kind of braking force equiblibrium mass distribution, and the stop buffer of 3 brakings that braking force is big, safe and reliable promptly when stopping central sill, also stops two vehicles, forms the structure of 3 three-dimensional brakings.
The purpose of this utility model realizes by following measure.Car side brake is installed on the railway stock rail successively, central sill drg and stop drg, three brake groups become the utility model stop buffer thus.Stop central sill by the central sill drg when vehicle is slipped away, stop two wheels by car side brake simultaneously, form 3 brakings simultaneously, by stopping drg reinforcement barrier effect, make the vehicle stop motion of slipping away at a high speed at last.Car side brake is made up of brake and screw press device, on two stock rails, is linked to be an integral body with lacing wire about brake is installed in respectively, and the friction force that produces by the screw press device stops wheel movement.The central sill drg is made up of striker, main frame, Brake Block and screw press device.Main frame is linked to be an integral body with pin with striker and Brake Block by four supports, and Brake Block is installed on the stock rail, axisymmetric rectangular pyramid structure in the composition, and impulsive force divides balancing, and the friction force that produces by the screw press device stops the central sill motion.Stop drg, that is to say the screw press device, it is linked to be an integral body with two string screws with two fan rail clip, and screw rod and screw are blocked in top, and the stock rail rail head is blocked in the bottom.During the screw rod backspin, push down laminated spring, laminated spring is pushed down the friction seat, and the friction seat is pushed down plane on the stock rail rail head; While two fans on rail clip and moves, and blocks the lower plane of rail head both sides, leans on the friction force of these three faces, rises to stop brake action.And, having good frictional behaviour because rail clip is to be made by cast steel, antifriction and friction force are big.
Describe in detail below in conjunction with the utility model accompanying drawing
Fig. 1 is for by car side brake, central sill drg with stop the scheme drawing of the utility model stop buffer that drg is formed.
Fig. 2 looks and partial schematic sectional view for the master of car side brake.
Fig. 3 is that the master who stops drg looks the cross-sectional schematic with A-A.
By Fig. 1 the utility model stop buffer by being installed on car side brake, the central sill drg on the circuit stock rail successively and stopping that drg forms.
Form by brake [1] and screw press device [2] by Fig. 2 car side brake.Brake [1] is formed a whole by an armful catch [3], frictional groove [4], reinforced rib [5,6], and reinforced rib [5,6] will be embraced catch [3] and frictional groove [4] solder together.Frictional groove [4] is buckled on the stock rail [7], and the top is provided with screw press device [2], and frictional groove [4] and stock rail [7] are stuck.Screw press device [2] is made up of screw rod [10], screw [11], laminated spring [12], friction seat [13], rail clip [14] and string screw [28].Screw rod [10] is pushed down laminated spring [12] along screw [11] backspin, laminated spring [12] is pushed down friction seat [13], friction seat [13] is pushed down frictional groove [4], move on rail clip [14] simultaneously, block stock rail [7] rail head both sides lower plane, interplanar on frictional groove [4] and stock rail rail head has thus just produced three friction faces that face contacts between rail clip [14] and stock rail rail head both sides lower plane, by the friction force on this friction face, car side brake stops wheel movement.And because wheel clamp [14] is made for cast steel, have antifriction and increase the characteristic of friction, make this car side brake have very big braking force.About car side brake on two rails be linked to be an integral body with angle steel [8,9].
Form by striker [15], main frame [16], Brake Block [17] and screw press device [2] by Fig. 1 central sill drg.With pin [18,19,20] striker [15], main frame [16], Brake Block [17] and screw press device [2] are linked to be an integral body, form a middle axisymmetric rectangular pyramid structure, make impulsive force divide balancing.Striker [15] is made up of buffer head [21] and buffering offset plate [22], is installed in main frame [16] top.Main frame [16] supports [24] by preceding support [23] and back to be formed, and is installed on the Brake Block [17].Brake Block [17] is made up of inside brake rail [25], outer braking rail [26] and seat board [27], and screw press device [2] is housed on the seat board [27], and Brake Block [17] is installed on the stock rail [7].The friction force that produces by screw press device [2] stops the central sill motion.
