Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 is the hydraulic schematic diagram according to hydraulic motor controlled of the present invention system.
Embodiment
Below with reference to accompanying drawing and combine embodiment to specify the present invention.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
As shown in Figure 1, the control system of present embodiment comprises 10, one hydraulic control pilot proportional multi-path reversing valves 30 of two hoist motors and two three-position four-way valves 20.
Each hoist motor 10 comprises the first motor hydraulic fluid port C and the second motor hydraulic fluid port D, through control the advancing of hoist motor 10, oil extraction direction, can control the sense of rotation of hoist motor, thereby control the sense of rotation of elevator.
In this hydraulic motor controlled system, accomplish the control requirements such as speed governing of each hoist motor 10 by a hydraulic control pilot proportional multi-path reversing valve 30.Hydraulic control pilot proportional multi-path reversing valve 30 comprises pressure hydraulic fluid port P, oil drain out T, the first oil outlet A and the second oil outlet B, has also comprised two guide's control end a1 and a2.
Each three-position four-way valve 20 has the meta function, is preferably solenoid valve.As shown in Figure 1; Each three-position four-way valve 20 is provided with hoist motor 10 corresponding one by one and each other parallelly connectedly, and three-position four-way valve 20 comprises first hydraulic fluid port 1, second hydraulic fluid port 2, the 3rd hydraulic fluid port 3 and the 4th hydraulic fluid port 4, wherein; Each first hydraulic fluid port 1 is communicated with the first oil outlet A; Each second hydraulic fluid port 2 is communicated with the second oil outlet B, and each the 3rd hydraulic fluid port 3 is communicated with the first motor hydraulic fluid port C of corresponding hoist motor, and each the 4th hydraulic fluid port 4 is communicated with the second motor hydraulic fluid port D of corresponding hoist motor.Wherein three-position four-way valve 20 can be replaced by other selector valve with meta function.
Above embodiment's hoist motor control system is suitable for realizing the order work of two hoist motors, can be through selection selector valve meta function, and figure place, control mode is to reach the purpose of opening the work of two elevator order.
For example, when each hoist motor of needs is worked in order, open hydraulic control pilot proportional multi-path reversing valve 30, the pressure hydraulic fluid port P and the first oil outlet A are communicated with, oil drain out T is communicated with the second oil outlet B.At this moment, the hoist motor 10 that is positioned at the left side if desired among Fig. 1 rotates and is positioned at hoist motor 10 stalls on right side, only need make the three-position four-way valve 20 that is positioned at the right side be in meta, and the three-position four-way valve 20 that is positioned at the left side is in working position.The three-position four-way valve 20 in left side has two kinds of situation when being in working position; When making left side three-position four-way valve 20 switch to first hydraulic fluid port 1 with the connections of the 3rd hydraulic fluid port 3, when second hydraulic fluid port 2 is communicated with the 4th hydraulic fluid port 4; The first motor hydraulic fluid port C of the hoist motor 10 in left side is communicated with pressure oil; And the second motor hydraulic fluid port D is communicated with oil extraction, and left hydraulic motor 10 is rotated towards a direction; When first hydraulic fluid port 1 that makes left side three-position four-way valve 20 with the connections of the 4th hydraulic fluid port 4, when second hydraulic fluid port 2 is communicated with the 3rd hydraulic fluid port 3; The first motor hydraulic fluid port C of the hoist motor 10 in left side is communicated with oil extraction; And the second motor hydraulic fluid port D is communicated with pressure oil, and left hydraulic motor 10 is rotated in the opposite direction.
In addition, selector valve of the present invention is not limited to the form that above embodiment provides, and for example, in a unshowned embodiment, above three-position four-way valve 20 can be realized with the hydraulic control valve of other control type such as two-position four-way valve or commutation function.At this moment; Control from the oil circuit break-make between hydraulic control pilot proportional multi-path reversing valve 30 and the respective motors by the change in location of two-position four-way valve; Thereby control corresponding motor start and stop, motor turn to control then the switching of the valve position through hydraulic control pilot proportional multi-path reversing valve 30 realize.
Above embodiment's hoist motor control system provides a kind of new multireel to raise the way of realization of motor alternation, and this new model can enoughly utilize the plain mode that directional control valve switches oil circuit to realize the order work that multireel is raised motor.Be that example has been explained the present invention only wherein, having under the situation of more a plurality of hoist motors that only needing increases the selector valve corresponding with hoist motor, and proportional multi-path reversing valve is constant with two hoist motors.Therefore, compared with prior art, reduced the usage quantity of the pilot proportional multi-path reversing valve that cost is higher, hydraulic element are more; Replace cost three-position four-way valve lower, simple in structure, therefore, can practice thrift cost; Simplify hydraulic system; Reduce hydraulic element, reduce fault, control system is for ease of maintenaince safeguarded.
The control mode of hydraulic control pilot proportional multi-path reversing valve 30 except hydraulic control, can also use automatically controlled, manually control pilot proportional multi-path reversing valve and substitute, also can be the proportional multi-path reversing valve of direct control.Adopt proportional multi-path reversing valve can pass through rotational velocity to the adjusting control hoist motor of flow.
Above embodiment's hydraulic motor controlled system relates to many oil hydraulic motors working equipment and utilizes selector valve to switch a kind of new model of its order of work; Be applicable to that multireel is raised but the various occasions of orderliness work; Especially can directly apply in the oil hydraulic circuit of all-hydraulic walking type pile-driving frame, be used for having controlled frame elevator and secondary elevator.
From above description, can find out; The above embodiments of the present invention have realized following technique effect: raise motor at multireel and do not work simultaneously; And when work under the situation, can make hoist motor according to the work of selector valve commutation sequence orderly, realizes that the Thomas reaches the switching of action; Can reduce one or join proportional multi-path valve and one or more guide's handle more than existing technology, and replace with one group of solenoid directional control valve.Practice thrift to the full extent under the condition of cost, reach the purpose of hoist motor order work.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
