This design proposal adds the arresting gear on the water pump vehicle, on the pump vehicle's disc brake paired mounting in the orbital both sides, the disc brake needs the pressure oil to use the hydraulic pressure station supplies which installs in the pump vehicle, uses the hydraulic pressure to open, not when pressure the small dish shape spring applies the brake, to use holds the axle brake way. This brake way belongs to the accident security, namely, regardless of any reason causes the hydraulic system to lose presses (power failure, solenoid valve not to act and so on), the brake may cause the pump vehicle safety arrestment under the small dish shape spring action of force.
This design braking system use disc brake, may in the limited arrangement of equipment space, the multi-establishment brake unit, cause the pump house lift system's brake fade probability to drop to as far as possible is smallest. Uses the symmetrical expression pipeline arrangement, by the balanced various brakes' between operating time, guaranteed applies the brake synchrony and reliability. Moreover, the hydraulic pressure pumping station has used the Neutral high hydraulic pressure actuation design and the small work current capacity, reduces the hydraulic system along the regulation resistance loss and the local pressure loss, reduces the pipeline interior fat liquor hit. Above each characteristic may indicate: The hydraulic pressure disc type braking system is a set often shuts the braking system, has the brake principle succinctly compared with block brake's system reliable, on the floodgate responds quickly, Tray shape brake synchrony good and so on characteristics.
Because before the pump house promotion, must make the brake loose floodgate first. Pump house when movement, meets the special reason (for example breaks rope) when needs the emergency brake. Therefore in a design has established the pressure switch and the P606 gravity sensor. By examines the system pressure and the pump house hauling condition and sends in the examination value first PLC. Realizes the automatic control, and can meet the sudden outbreak. For example: The towing device breakdown produces when the accelerating-coasting, the steel wire break the rope or the system power failure, the brake should on the automatic floodgate, the emergency brake.
