The invention discloses an auxiliary brake device for a monorail excursion train. The auxiliary brake device comprises a brake block (2) and a brake block installation frame (3), wherein the brake block (2) is located under a rail top plate (1), can press a rail top plate bottom surface (11) when the train brakes and can slide or produce a sliding trend to supply resistance to the train, and the direction of the resistance is opposite to that of operating of the train; and the brake block installation frame (3) is used for being fixedly or movably connected with the brake block. A pressing device (5) capable of adjusting the positive pressure between the brake block and the rail top plate bottom surface is connected between the brake block installation frame and a train bogie framework (4). According to the auxiliary brake device for the monorail excursion train, the brake capacity of the train is improved through the brake block, and the brake force can be increased to be maximum without increasing the self weight of the train; and under assistance of the auxiliary brake device, the train can be reliably and safely stopped with the gradient being 14% on a rainy day under full load downgrade operation and emergency braking working conditions. In addition, the pressing device of the auxiliary brake device adopts a power-losing braking mode, and the safety of the train is high.
Description
Technical field
The present invention relates to single track tourist coach field, particularly, relate to a kind of single track excursion train complemental brake system.
Background technology
Existing single track excursion train line slope is less, and train relies on the electricity loss brake locking wheel driving motor to carry
Realizing brake hard and parking braking, when descending performs brake hard, wheel is by rapid locking, wheel and interorbital motion
Becoming simple sliding, the especially attachment coefficient (i.e. coefficient of friction) between rainy day, wheel track can drastically decline, in fact it could happen that water skiing is existing
As.At line slope more than 8%, rainy day, train be fully loaded with descending brake hard operating mode under, only by train from the wheel reformed
Adhesive force (i.e. frictional force) between rail is inadequate, and existing emergency braking system can not be in the distance that relevant national standard specifies
Stopping, even driving causes security incident, accordingly, it would be desirable to a kind of scheme improves this phenomenon.About single track in prior art
The scheme of excursion train auxiliary braking is introduced less, and Chinese patent 200920191953.5 discloses a kind of automatically operated retarder, it
Being to arrange a pendulum on the vehicle frame of tourist coach, this pendulum can work as visit according to the state that the lands swing of tourist coach
During car descending, pendulum swings forward and brake cable is strained, and to reach the purpose slowed down, is carried by plumb-bob gravity in the program
Braking for pulling force, its brake force provided is limited, if increasing brake force by the weight increasing pendulum, will certainly increase
The deadweight of tourist coach so that brake force required during tourist coach descending increases, and therefore, the braking effect of the program is relatively difficult to ensure card.
Summary of the invention
Present invention aim at providing a kind of single track excursion train complemental brake system, to solve existing single track excursion train
Climbing capacity is limited, it is impossible to be applicable to the construction of natural scenic spots with a varied topography and single track excursion train running rail over the ground
The natural conditions such as shape landforms destroy big problem.
For achieving the above object, the invention provides a kind of single track excursion train complemental brake system, including being positioned at track
Top board (1) lower section and can compress when train braking track top board bottom surface (11) and slidably or generation tendency toward sliding and to train
Produce the brake block (2) of the resistance contrary with traffic direction, and for the fixing system connected or be flexibly connected described brake block
Motion block installing rack (3), is connected between described brake block installing rack with train bogie framework (4) and has scalable brake block and track
The hold down gag (5) of normal pressure between top board bottom surface.Described hold down gag upper end is fixing with bogie frame to be connected, lower end and system
Motion block installing rack (3) connects.
Further, described brake block installing rack (3) includes pivoted arm (31) and bracing frame (32), and described pivoted arm one end is installed
Having described brake block, the pivoted arm other end to be connected with described hold down gag, support frame as described above upper end is fixing with bogie frame to be connected,
Lower end extends the lower section of track top board hinged with described pivoted arm, and the pin joint between pivoted arm and bracing frame be positioned at brake block with
Between hold down gag so that hold down gag can drive pivoted arm to rotate around the pin joint between pivoted arm and bracing frame and make the other end
Brake block upwards withstands track top board bottom surface or downward away from track top board bottom surface, thus realizes the work of this complemental brake system
Or reset.
Further, described brake block is fixed or movable is hinged on pivoted arm.
Preferably, described hold down gag uses hydraulic cylinder or cylinder.
Further, described hydraulic cylinder or cylinder use the single-acting spring brake cylinder of dead electricity braking model.
Further, described brake block is provided with along the two ends in train length direction and sticks up to the direction away from track top board bottom surface
Bent angular guide surfaces (22), for producing the contact surface (21) of slip or tendency toward sliding with track top board bottom surface even on brake block
It is connected between two angular guide surfaces.
Further, described brake block slides for producing with track top board bottom surface or covers on the contact surface of tendency toward sliding
There is rubber cover.
Beneficial effect: the present invention increases train and interorbital malleation by compressing the brake block of track top board bottom surface
Power, thus increase road wheel and interorbital adhesive force (i.e. frictional force), improve train braking ability, it addition, the system of the present invention
Dynamic device just can increase maximum braking force without increasing train deadweight, the oblique component that the deadweight on the one hand preventing train from increasing produces
Increasing train braking difficulty, on the other hand, when need not use this complemental brake system, train load will not be increased.Pass through
It is demonstrated experimentally that under the assosting effect of this brake unit, train the gradient be 14%, rainy day, train be fully loaded with descending and promptly make
During the operating mode moved, it is possible to reliable, safe parking.
The present invention, while increasing train and interorbital normal pressure, also produces between brake block and track top board bottom surface
A pair frictional force, i.e. adds a friction pair at brake block and interorbital, further increases the stopping power of train, make
Train can be reliable, safe parking.
It addition, the hold down gag of the present invention uses the single-acting spring brake cylinder of dead electricity braking model, use dead electricity braking,
It is effectively guaranteed the safety 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 further detailed explanation.
