Description
Technical field
The utility model relates to a kind of loading brake system, specifically is that a kind of electric drive wheel quarry tipper loads brake equipment, belongs to and loads the brake system applied technical field.
Background technology
At present, the loading brake system of electric drive wheel quarry tipper adopts the open and close of hydraulic pilot control relay valve usually both at home and abroad, and then control flows is loaded braking to the flow break-make of drg thereby accomplish.
Because quarry tipper belongs to transit vehicle, entrucking and discharging are more frequent, are the safety of assurance quarry tipper when entrucking and the discharging; Quarry tipper is typically equipped with the loading brake system, and when charging or discharging, driving engine is not flame-out; To the back axle brake activation, promptly so-called loading braking is because the loading brake system of hydraulic pilot control is relatively complicated; Therefore number of elements is more, the pipeline connection is loaded down with trivial details, thereby causes difficulty of trouble tracing, and has certain hysteresis quality.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of electric drive wheel quarry tipper to load brake equipment, and this system is independent of driving, emergency brake system; And it is simple in structure; A button by in the operator's compartment is independently controlled, simple operation, and safe reliability is high.
To achieve these goals; The utility model is realized through following technical scheme: a kind of electric drive wheel quarry tipper loads brake equipment; Comprise and load the braking valve body, load the braking valve body and constitute by solenoid directional control valve I, reducing valve, shuttle valve, solenoid directional control valve II, oil return interface, oil sources interface, pressure sensor I, pressure sensor II and hydraulic fluid port; The solenoid directional control valve I is connected with the oil sources interface; Reducing valve is connected with shuttle valve with the solenoid directional control valve I respectively, reducing valve be connected with the pressure sensor II through hydraulic fluid port again after shuttle valve is connected, the solenoid directional control valve II is passed through oil circuit and is connected with the pressure sensor I; The solenoid directional control valve I is connected with the oil return interface through oil circuit respectively with the solenoid directional control valve II; Load the braking valve body and adopt screw-in cartridge valve, be integrated in and load the brake activation valve group, be convenient to piping layout.
The principle of work of the utility model is: quarry tipper is in charging or during the discharging state, applies electric signal, and electromagnetic switch valve events, the hydraulic oil that steering pump is supplied with get into the drg of back axle after through solenoid directional control valve, reducing valve, shuttle valve; Another solenoid directional control valve cuts off the propons braking simultaneously, even mistake is stepped on brake pedal, and can be to the propons brake activation yet.
The beneficial effect of the utility model is: system construction is simple, and control is accurate in real time, simple operation, and safe reliability is high, and convenient inspection fault is convenient to maintenance.
Description of drawings
Fig. 1 is the systematic schematic diagram of the utility model.
Among the figure: 1, load the braking valve body, 2, the solenoid directional control valve I, 3, reducing valve, 4, shuttle valve, 5, the solenoid directional control valve II, 6, the oil return interface, 7, the oil sources interface, 8, the pressure sensor I, 9, the pressure sensor II, 10, hydraulic fluid port.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1; A kind of electric drive wheel quarry tipper loads brake equipment; Comprise and load braking valve body 1, load braking valve body 1 and constitute by solenoid directional control valve I 2, reducing valve 3, shuttle valve 4, solenoid directional control valve II 5, oil return interface 6, oil sources interface 7, pressure sensor I 8, pressure sensor II 9 and hydraulic fluid port 10; Solenoid directional control valve I 2 is connected with oil sources interface 7; Reducing valve 3 is connected with shuttle valve 4 with solenoid directional control valve I 2 respectively; Reducing valve 3 be connected with pressure sensor II 9 through hydraulic fluid port 10 again after shuttle valve 4 is connected; Solenoid directional control valve II 5 is connected with pressure sensor I 8 through oil circuit, and solenoid directional control valve I 2 is connected with oil return interface 6 through oil circuit respectively with solenoid directional control valve II 5, loads braking valve body 1 and adopts screw-in cartridge valve.
The working process of the utility model is: when quarry tipper is in charging or discharging state; Operating personal only needs to press the reprinting stop button at operator's compartment, for the electromagnet of solenoid directional control valve I 2 applies electric signal, 2 actions of solenoid directional control valve I; The hydraulic oil that steering pump is supplied with is through oil sources interface 7; Behind solenoid directional control valve I 2, reducing valve 3 and shuttle valve 4, from the drg of hydraulic fluid port 10 entering back axles, along with the rising of pressure; Pressure oil impels brake plunger to overcome spring force to act on the brake disc that is installed on back axle, pins vehicle implementation and loads braking; Solenoid directional control valve II 5 is cut off the propons braking simultaneously, even mistake is stepped on brake pedal, and can be to the propons brake activation yet.
