The brake device is started, the control end sends out a brake signal, the electromagnetic coil is electrified, the electromagnetic force is generated by the electromagnetic coil to attract the top surface of the rail, the electromagnet brake body and the steel rail are attracted and braked, and the ladder car is stopped; after the braking action is completed, the electromagnetic brake pad is pulled to reset by the spring lifter fixed under the ladder car. In addition, the control end is provided with an emergency brake button, when the ladder car encounters danger and needs emergency braking, the ladder car can be ensured to realize manual quick braking under the emergency condition, and the sensor can control the maximum braking force of the train, so that the ladder car is ensured not to overturn under the condition of manual emergency braking.
The braking system is started, the controller controls the oil pressure of the hydraulic cylinder to increase so as to push the telescopic shaft of the hydraulic cylinder, and the brake pad and the steel rail reach a certain pressure under the action of the oil pressure and generate friction so as to realize braking and stopping. When the sensor detects that the brake pad and the rail reach a certain pressure, the sensor feeds back information to the controller, and the controller controls the oil pressure of the hydraulic cylinder to be unchanged. The brake pad automatically resets after the brake system is turned off. The clamping rail wheels at two sides of the hybrid power ladder car are in close contact with the steel rail, and the clamping rail wheels automatically rotate along with the running of the hybrid power ladder car, so that the hybrid power ladder car can resist lateral movement and overturning and simultaneously reduce friction with a rail. In addition, the rim of the hybrid power ladder car has the function of preventing the hybrid power ladder car from sideways moving and overturning to a certain extent.
Braking system: the braking system is mainly used for braking of vehicles and is a main means for preventing danger and realizing emergency stop of vehicles. The brake pad is a main component for braking, when the brake is needed, a brake system is started, the brake pad is contacted with the rail, and the brake pad is rubbed with the rail to achieve the braking effect of the hybrid power ladder car. The telescopic shaft of the hydraulic cylinder comprises a telescopic shaft, an inner clamping piece and an adjusting nut, wherein the telescopic shaft directly penetrates through the center of the brake pad, the adjusting nut and the inner clamping piece are positioned on two sides of the brake pad and used for fixing the brake pad, and the adjusting nut is positioned at the end part of the telescopic shaft. The telescopic shaft of the hydraulic cylinder directly controls the position of the brake pad, and the inner clamping piece and the adjusting nut are used for fixing the position of the brake pad. The brake block adopts the bolt to be connected with interior card piece, interior card and telescopic shaft rigid connection, guarantees that the brake block does not take place to remove and rotate. The adjusting nut is fixed on the outer side of the brake pad, so that the brake pad is prevented from moving outwards, the fixing effect of the brake pad is enhanced, and the brake pad and the telescopic shaft of the hydraulic cylinder are prevented from moving and rotating relatively. The hydraulic cylinder is used for controlling the oil pressure in the braking system, and the controller is used for controlling the hydraulic cylinder to reach a fixed pressure value set in advance. The controller directly controls the oil pressure of the hydraulic cylinder to increase after the braking system is started, and the brake pad and the rail generate friction under the action of the oil pressure to realize braking and stopping. The sensor is installed on the hydraulic cylinder for detecting the oil pressure in the hydraulic cylinder. The sensor and the controller can also be connected by a wire, and the sensor feeds back information to the controller by the wire; when the sensor detects that the pressure set by the controller is reached between the brake pad and the rail, the controller directly controls the oil pressure in the hydraulic cylinder to be unchanged, and the controller is controlled by the control end to control the oil pressure in the hydraulic cylinder; after the braking system is closed, the controller controls the brake pad to automatically reset; in the normal use process, the abrasion thinning of the brake pad can influence the braking effect. When the preset fixed pressure value cannot be reached, the sensor feeds back to the controller that the oil pressure value in the hydraulic cylinder does not reach the pressure value set by the controller, and the controller controls the oil pressure of the hydraulic cylinder to continue to increase until the preset fixed pressure value is reached, so that the braking effect is ensured. In order to avoid the brake block from being worn to a certain extent, the telescopic shaft and the steel rail generate friction, the length of the telescopic shaft is controlled in a certain range, and when the brake block is worn to a replacement extent, the telescopic shaft cannot continue to stretch and still keep a proper distance with the rail. The controller is connected with the alarm system, when the telescopic shaft cannot extend, the sensor detects that the pressure of the hydraulic cylinder is insufficient and feeds back to the controller, and the controller triggers the alarm system to remind to replace the brake pad. The hydraulic cylinder controls the telescopic shaft of the hydraulic cylinder to control the position of the brake pad, so that braking is realized. The connecting shaft is used for fixing the position of the hydraulic cylinder and ensuring that the position of the hydraulic cylinder is not changed. The hydraulic cylinder fixer, the connecting shaft and the hydraulic cylinder are connected by adopting high-strength bolts, so that the hydraulic cylinder fixer, the connecting shaft and the hydraulic cylinder are prevented from relative movement and rotation. The whole braking device is fixed at a proper position on the axle through the hydraulic cylinder fixer, so that the brake pad keeps a certain distance from the rail in a non-working state of the system, and braking can be effectively realized in the working state. When the whole braking system works, the braking system and the axle are ensured not to displace and rotate.
