Description
Technical field
The utility model relates to a kind of hydraulic system of monolever control, for realizing the multi-joint compound action of mechanical hand for loader, belongs to mechanical hand for loader action control technical field.
Background technology
Conventionally, the operating grip of loader comprises control stick and pilot handle, and they are respectively used to control one and two interlocks of mechanical hand for loader and do, and need multiple handles to coordinate realize for complicated manipulator behavior control.Due to the limited space of driver's cabin, handle is not suitable for installing too many, and operator must frequently switch back and forth between each handle, operation inconvenience, and labour intensity is larger, thereby causes the manipulator of work complexity to be not suitable for using on loader.In this context, simplify the control of many handles, meet the multi-joint action of mechanical hand for loader simultaneously and just seem particularly important.
Summary of the invention
For above-mentioned existing technical problem, the utility model provides the hydraulic system of the multi-joint action of a kind of monolever control mechanical hand for loader, simplify original many handles control, by single handle, mechanical hand for loader fluid pressure line electromagnetic valve is controlled, realize the multi-joint action of manipulator.
The utility model comprises monolever, distributing valve, fuel tank and working barrel, and monolever is by pressure signal control distributing valve, and fuel tank is communicated with the in-line of distributing valve through working barrel.Improvements are, multiple handle control buttons are also installed on monolever, and each handle control button is electrically connected respectively a controlled electromagnetic valve, and handle control button and electromagnetic valve and power supply are connected to form loop one to one; The oil duct interface of each electromagnetic valve one end connects the vent line of distributing valve, and the oil duct interface of the other end connects respectively the fluid pressure line port of an executing agency of manipulator.So, loader distributing valve Yi road hydraulic oil enters into the oil duct interface of the electromagnetic valve other end, and handle control button on monolever is corresponding one by one with electromagnetic valve, by operating different handle control buttons, corresponding electromagnetic valve is connected, hydraulic oil enters into the fluid pressure line of corresponding manipulator executing agency, thereby realizes by the multi-joint action of single handle control mechanical hand for loader.
Further, belonging to the changing in tire car of loader one class, four handle control buttons are installed on described monolever, the oil duct interface of four controlled electromagnetic valve one end is all communicated with the vent line of distributing valve, the oil duct interface of the other end is communicated with respectively the fluid pressure line of tyre rotation motor, translation oil cylinder, overall angling cylinder and the clamping cylinder of manipulator, can control manipulator complete the multi-joint actions such as tyre rotation, translation, entirety revolution and clamping by single handle.
Further, described electromagnetic valve adopts two-position four-way solenoid valve.
Further, described power supply is+24V dc source that each electromagnetic valve is all connected to form loop with power supply with corresponding handle control button.
Visible, adopt this hydraulic system to have easy and simple to handle, workload is little, can realize the advantage of compound action.Because operating personnel need to frequently not change hand in operating process, both reduced working strength, improve again operating efficiency.
Brief description of the drawings
Fig. 1 is overall theory diagram of the present utility model;
Fig. 2 changes in wheel car embodiment handle control button to the theory diagram between executing agency.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this hydraulic system comprises monolever, distributing valve, fuel tank and working barrel, and monolever is by pressure signal control distributing valve, and fuel tank is communicated with the in-line of distributing valve through working barrel.Improvements are, multiple handle control buttons are also installed on monolever, and each handle control button is electrically connected respectively a controlled two-position four-way solenoid valve, and handle control button, corresponding electromagnetic valve are connected to form loop with+24V dc source; The oil duct interface of each electromagnetic valve one end is communicated with the vent line of distributing valve, and the oil duct interface of the other end is communicated with the fluid pressure line port of an executing agency of manipulator.
In other words, the compound action of supposing mechanical hand for loader needs n connection fluid pressure line to go to control, consider that the electromagnetic valve that n two-position four-way is set on manipulator forms electromagnetic valve group, the oil duct interface of these electromagnetic valve one end all connects from distributing valve oil circuit out, the oil duct interface of the other end connects respectively the n connection fluid pressure line of manipulator, and on monolever, arrange n respectively with n electromagnetic valve handle control button one to one, and the handle control button of correspondence and electromagnetic valve are connected with+24V dc source.In the time that loader is worked, the left and right directions motion forwards, backwards of operation sheet handle, produce the pressure signal of controlling distributing valve, distributing valve oil circuit out enters into electromagnetic valve group, press the signal of telecommunication of the handle control button generation electromagnetic valve switch on monolever simultaneously, signal of telecommunication control enters into the trend of electromagnetic valve group oil circuit, respective line in controlled solenoid valve is connected, hydraulic oil enters into the fluid pressure line of corresponding manipulator executing agency, thereby realizes by the multi-joint action of single handle control mechanical hand for loader.
As shown in Figure 2, change tire car as example taking loader amelioration product, the action of changing tire car manipulator comprises the revolution of revolution, translation, body and the folding of tong tetrad action altogether, is mainly used in changing tire for large-tonnage engineering machinery such as mine trucks.Now this tetrad action is combined on a monolever and is controlled, the electromagnetic valve composition electromagnetic valve group of four two-position four-ways only need be installed on manipulator, the oil duct interface of this electromagnetic valve group one end connects the vent line from distributing valve, and distributing valve connects fuel tank by working barrel, the oil duct interface of the other end is communicated with respectively the tetrad fluid pressure line of manipulator executing agency, be that each two-position four-way solenoid valve connects respectively tire rotary motor, translation oil cylinder, the fluid pressure line of entirety angling cylinder and clamping cylinder, and the handle control button of controlling these four electromagnetic valves is centrally mounted on operation sheet handle, four handle control buttons on known monolever are controlled respectively the revolution of manipulator, translation, four actions such as body revolution and tong folding.In the time that loader is worked, operating personnel press handle control buttons different on monolever according to actual conditions, corresponding electromagnetic valve is connected, hydraulic oil enters corresponding mechanical hand hydraulic pipeline, thereby utilize single handle control manipulator to realize complicated difference action, and then complete whole operation of changing tire.
