Embodiment
The embodiment to the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, voltage-controlled damping hydraulic pushing device of the invention, by beaer 1, voltage-controlled body 2, spring base 4, compression bullet
Spring 6, off-load joint 7, big compression spring 9 and shock reducing structure 10 are constituted, and the upper end of beaer 1 uses with instrument string and is threadedly coupled, stress
It is stepped cylinder type hole in the middle of body 1, voltage-controlled body 2 is put into the lower end cylindrical hole of beaer 1, it is oriented at the voltage-controlled center of body 2
The cylindrical type connecting rod of lower protrusion, the downwardly projecting cylindrical type connecting rod of voltage-controlled body 2 withstands on the upper end of spring base 4, and compression spring 6 is arranged on
The lower end of spring base 4, after spring base 4 is connected with compression spring, in the cylindrical hole for being put into off-load joint 7, spring base 4 and compression
Spring 6 can be considered piston, and the voltage-controlled lower end of body 2 is in contact with spring base 4, and beaer 1 is used with off-load joint 7 and is threadedly coupled.Water
The power that stream is acted on voltage-controlled body 2, so push the spring seat 4 and compression spring 6 in the cylindrical hole of off-load joint 7 to moving down
It is dynamic, form (A enters-B and gone out) fluid passage；The centre bore of off-load joint 7 is built with O-ring 3, the lower end of off-load joint 7 and shock reducing structure 10
Using spacer pin 8 through connection, the middle part reduced diameter portion of off-load joint 7, which is provided with equally distributed hole, each hole, is mounted with 1 together
Shaft roller 5；The lower end of off-load joint 7 is provided with cylindrical type through hole, and for installing spacer pin 8, spacer pin 8 is arranged on off-load joint 7；
The reduced diameter portion of shock reducing structure 10 is provided with big compression spring 9, and centre is provided with elongated hole, and spacer pin 8 passes through the elongated hole.Shock reducing structure 10 is the bottom of at
During portion's stress, by the elasticity of big compression spring 9, shock reducing structure 10 is slowly moved up, play a part of damping.
