Description

A kind of single track excursion train complemental brake system
Technical field
The present invention relates to single track tourist coach field, particularly, is related to a kind of single track excursion train complemental brake system.
Background technology
Existing single track excursion train line slope is smaller, the electricity loss brake locking wheel that train is carried by driving motor To realize emergency braking and parking braking, when descending performs emergency braking, wheel is by rapid locking, the movement of wheel and interorbital It is changed into simple sliding, the attachment coefficient (i.e. friction coefficient) especially between the rainy day, wheel track can drastically decline, in fact it could happen that water skiing is existing As.In the case where line slope is fully loaded with the operating mode of descending and emergency braking more than 8%, rainy day, train, the wheel only by train from reformation Not enough, existing emergency braking system cannot be as defined in relevant national standard in distance for adhesive force (i.e. frictional force) between rail Parking, or even driving cause security incident, and therefore, it is necessary to a kind of scheme to improve this phenomenon.In the prior art on single track The scheme of excursion train auxiliary braking is introduced less, and Chinese patent 200920191953.5 discloses a kind of automatically operated retarder, it It is that one pendulum of setting, the pendulum can work as visit according to the state swing that lands of tourist coach on the vehicle frame of tourist coach During car descending, pendulum swings forward and tenses brake cable, to achieve the purpose that deceleration, is carried in the program by plumb-bob gravity Brake for pulling force, the brake force that it is provided is limited, if increasing brake force by increasing the weight of pendulum, will certainly increase The dead weight of tourist coach so that required brake force increase during tourist coach descending, therefore, the braking effect of the program is relatively difficult to guarantee.
The content of the invention
Present invention aims at a kind of single track excursion train complemental brake system is provided, to solve existing single track excursion train Climbing capacity is limited, it is impossible to suitable for natural scenic spots with a varied topography and single track excursion train running rail construction over the ground The natural conditions such as shape landforms destroy the problem of big.
To achieve the above object, the present invention provides a kind of single track excursion train complemental brake system, including positioned at track Below top plate (1) and can be compressed in train braking track top board undersurface (11) and slidably or generation tendency toward sliding and to train The brake block (2) of the resistance opposite with traffic direction is produced, and for being fixedly connected with or being flexibly connected the system of the brake block Motion block mounting bracket (3), adjustable brake block and track are connected between the brake block mounting bracket and train bogie framework (4) The pressing device (5) of normal pressure between top board undersurface.The pressing device upper end is fixedly connected with bogie frame, lower end and system Motion block mounting bracket (3) connects.
Further, the brake block mounting bracket (3) includes pivoted arm (31) and supporting rack (32), pivoted arm one end installing There is the brake block, the pivoted arm other end is connected with the pressing device, and support frame as described above upper end is fixedly connected with bogie frame, Lower end extends the lower section of track top plate and is hinged with the pivoted arm, and the hinge joint between pivoted arm and supporting rack be located at brake block with Between pressing device so that pressing device can drive hinge joint of the pivoted arm between pivoted arm and supporting rack to rotate and make the other end Brake block withstands track top board undersurface or downward away from track top board undersurface upwards, so as to fulfill the work of this complemental brake system Or reset.
Further, the brake block is fixed or movable is hinged on pivoted arm.
Preferably, the pressing device uses hydraulic cylinder or cylinder.
Further, the hydraulic cylinder or cylinder use the single-acting spring brake cylinder of dead electricity braking model.
Further, the both ends in the brake block along train length direction, which are equipped with to the direction away from track top board undersurface, sticks up Bent angular guide surfaces (22), be used to produce with track top board undersurface on brake block slide or the contact surface (21) of tendency toward sliding even It is connected between two angular guide surfaces.
Further, the brake block is used to produce with track top board undersurface and is covered on the contact surface of slip or tendency toward sliding There is rubber protective layer.
Beneficial effect:The present invention increases the positive pressure of train and interorbital by compressing the brake block of track top board undersurface Power, so as to increase the adhesive force (i.e. frictional force) of traveling wheel and interorbital, improves train braking ability, in addition, the system of the present invention Dynamic device, which need not increase train dead weight, just can increase maximum braking force, the oblique component on the one hand preventing the increased dead weight of train from producing Increase train braking difficulty, on the other hand, when this complemental brake system need not be used, train load will not be increased.Pass through It is demonstrated experimentally that under the booster action of this brake apparatus, train the gradient be 14%, rainy day, train are fully loaded with descending and promptly make During dynamic operating mode, can reliably, the parking of safety.
The present invention also produces while the normal pressure of train and interorbital is increased between brake block and track top board undersurface A pair of of frictional force, i.e., it is secondary to add a friction in brake block and interorbital, further increases the stopping power of train, makes Train can reliably, safety parking.
In addition, the pressing device of the present invention uses the single-acting spring brake cylinder of dead electricity braking model, braked using dead electricity, It is effectively guaranteed the security of train.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages. Below with reference to figure, the present invention is described in further detail.
