Description
Technical field
The utility model relates to a kind of hydraulic jack actuator, especially relates to a kind of engineering vehicle and carries out oil cylinder safe hydraulic pressure locking-valve.
Background technique
Vehicle suspension lifting and steering hydraulic oil cylinder are critical components of vehicle lifting and steering hydraulic system, and the Security of its work and reliability are very important.The actuator of vehicle all adopts hydraulic transmission and hydraulic control technology.Elevating system with vehicle suspension is an example, and all adopting hydraulic jack at present is executive component.Its hydraulic system is made up of oil hydraulic pump, deadweight safety valve, hydraulic pressure locking-valve, hydraulic jack etc.In order to guarantee that security of system works reliably, hydraulic jack is after the oil pipe explosion, and the hydraulic pressure locking-valve is closed pipeline immediately, and workpiece safety is kept, and after fault was got rid of, mechanism is normal operation more then.
The model utility content
Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides a kind of engineering vehicle and carries out oil cylinder safe hydraulic pressure locking-valve, works reliably can guarantee security of system.
Technological scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of engineering vehicle is carried out oil cylinder safe hydraulic pressure locking-valve, comprises the anti-explosion safety valve body and is arranged on the interior anti-rupture valve core bar of anti-explosion safety valve body; On the anti-explosion safety valve body, be provided with oil flow channel; Anti-rupture valve core bar is provided with the catch that is used to seal oil flow channel; End face of described catch links to each other with spring on being arranged on anti-rupture valve core bar, the other end be arranged on the nut of preventing on the rupture valve core bar and touch mutually; The other end of described spring links to each other with the anti-explosion safety valve body.
The periphery of described anti-explosion safety valve body is provided with screw thread and links to each other with the contiguous block of oil cylinder.
Described safe hydraulic pressure locking-valve has 4.
Engineering vehicle of the present utility model is carried out oil cylinder safe hydraulic pressure locking-valve, when system works hydraulic oil enters first anti-explosion safety valve body from hydraulic fluid port in, hydraulic oil passes through oil flow channel, and in hydralic hose enters second anti-explosion safety valve body, hydraulic oil is by the oil flow channel of second anti-explosion safety valve body, enter the following active chamber of hydraulic jack from hydraulic fluid port, the piston rod that promotes hydraulic jack moves upward.When system overloads suddenly or meets accident, one in 2 hydralic hoses occurs breaking, the back pressure of anti-rupture valve core bar is suddenly zero, under acting force of the spring, drive catch the oil flow channel on the anti-explosion safety valve body is closed, thereby the path blockade at the oil pipe place of will breaking is realized safety interlocking, simultaneously another oil circuit still is a path, but system's proper functioning still.
The utility model is worked reliably in order to guarantee security of system, the working tubing of hydraulic jack adopts hydraulic dual circuit, after a hydraulic oil pipe explosion, hydraulic dual circuit anti-explosion safety locking-valve is closed this pipeline immediately, workpiece safety is kept, simultaneously another hydraulic oil pipe is connected automatically, but mechanism's proper functioning still, its main feature be efficient, safety, reliably reach simple in structure.The work operative characteristic that had both kept common automobile hydraulic system makes the vehicle hydraulic hydraulic system have safer more reliable operating feature again.
Beneficial effect: engineering vehicle of the present utility model is carried out oil cylinder safe hydraulic pressure locking-valve, and is simple in structure, designs ingenious, can just close this pipeline in the moment of system pipeline explosion, speed is fast, and the efficient height makes the vehicle hydraulic hydraulic system have safer more reliable operating feature.
Description of drawings
Fig. 1 is the structural representation of the valve core of anti-explosion safety locking-valve of the present utility model.
Fig. 2 is the catch closed condition schematic representation among Fig. 1.
Fig. 3 is the structural representation of automobile hydraulic system dual circuit of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
As depicted in figs. 1 and 2, carry out oil cylinder safe hydraulic pressure locking-valve for engineering vehicle of the present utility model.This safe hydraulic pressure locking-valve comprises anti-explosion safety valve body 1 and the anti-rupture valve core bar 2 that is arranged in the anti-explosion safety valve body 1; On anti-explosion safety valve body 1, be provided with oil flow channel 6; Anti-rupture valve core bar 2 is provided with the catch 3 that is used to seal oil flow channel 6; End face of described catch 3 links to each other with spring 4 on being arranged on anti-rupture valve core bar 2, the other end be arranged on the nut of preventing on the rupture valve core bar 25 and touch mutually; The other end of described spring 4 links to each other with anti-explosion safety valve body 1.Being provided with screw thread in the periphery of anti-explosion safety valve body 1 links to each other with the contiguous block of oil cylinder.
As shown in Figure 3, be automobile hydraulic system dual circuit of the present utility model.The utility model automobile hydraulic system dual circuit is made up of two hydraulic oil pipe assembly A and B.The both sides of anti-explosion safety valve body 1 connect piece about being connected with by bolt, and the junction plane place is equipped with the O RunddichtringO.During installation, at 2 ends of each hydraulic oil pipe assembly A or B 1 safe hydraulic pressure locking-valve is set respectively, like this, 2 hydraulic oil pipe assemblies need 4 safe hydraulic pressure locking-valves.When system works hydraulic oil enters first anti-explosion safety valve body 1 from hydraulic fluid port in, hydraulic oil is by oil flow channel 6, push catch 3 open, in hydralic hose enters second anti-explosion safety valve body 1, hydraulic oil is by the oil flow channel 6 of second anti-explosion safety valve body, push catch 5 open, enter the following active chamber of hydraulic jack from hydraulic fluid port, the piston rod that promotes hydraulic jack moves upward.When system overloads suddenly or meets accident, one in 2 hydralic hoses occurs breaking, the back pressure of anti-rupture valve core bar 2 is suddenly zero, under spring 4 active forces, drive catch 3, the oil flow channel on the anti-explosion safety valve body 16 is closed, thereby the path blockade at the oil pipe place of will breaking, realize safety interlocking, another oil circuit still is a path simultaneously, but system's proper functioning still.
