The invention discloses a triple hydraulic directional valve composite control device which comprises a handle, wherein the handle is connected to a control rod seat through a connecting rod; the control rod seat is connected with a multiway valve; a knuckle rod end I, a knuckle rod end II and a knuckle rod end III are mounted below the control rod seat; a knuckle bearing of the knuckle rod end I is mounted on a base; knuckle bearings of the knuckle rod end II and the knuckle rod end III are mounted on a duplex valve rod and a first valve rod respectively; the multiway valve is provided with three hydraulic pipelines; the knuckle rod end III, the knuckle rod end II and a knuckle rod end IV sequentially control directional valves of the three hydraulic pipelines; the upper end of the connecting rod is connected with the handle; the lower end of the connecting rod is connected with a locking rod; and the locking rod is connected with a limiting rod parallel to the connecting rod through a drop-shaped limiting rod seat. According to the triple hydraulic directional valve composite control device, three functions can be controlled with one handle, so that the operation of equipment or a vehicle is simpler, hardware components of the equipment or the vehicle are reduced, and the cost of the equipment or the vehicle is reduced.
Description
technical field [0001] The invention relates to a compound operating device for triple hydraulic reversing valves, which is a device for realizing triple compound operating with one handle, and belongs to the field of mechanical technology. Background technique [0002] The multi-way hydraulic reversing valve is a combination of more than two valve blocks to manipulate the movement of multiple actuators. According to the requirements of different hydraulic systems, it can combine safety valves, overload valves, oil supplement valves, diverter valves, brake valves, check valves, etc., so it has compact structure, simple pipeline, small pressure loss, and It is easy to install, so it is widely used in construction machinery, hoisting and transportation machinery and other walking machinery that requires the manipulation of multiple actuators. [0003] In order to simplify the operation, usually one operating handle has the function of applying different operating instructions...
