Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the right view of Fig. 1.
Specific embodiment
The present invention is described in further details below.Referring to Fig. 1,2, a kind of actuator hydraulic lock misplaces monitoring of structures,
Including actuator housing 1, piston 4 and center-pole 7, piston 4 is located in the piston mounting holes on actuator housing 1, center-pole 7
In in the centre bore of piston 4, piston 4 can be moved with respect to actuator housing 1, have hydraulic lock between piston 4 and center-pole 7,
When hydraulic lock is locked, piston 4 is unable to relative motion with center-pole 7, and when hydraulic lock is unlocked, piston 4 can be relative with center-pole 7
Motion；It is characterized in that：Actuator hydraulic lock dislocation monitoring of structures also includes support 2, microswitch 3, adjusting rod 5, the and of nut 6
Steel ball 8；There is a blind hole on the end face of center-pole 7, the blind hole is divided into two sections of left and right, and left section is light hole section, and right section is interior spiral shell
Line section, the aperture of the large diameter-ratio light hole section of the internal thread segment is big, and light hole section and the top of the external cylindrical surface of center-pole 7 of the blind hole are passed through
It is logical；5 points of adjusting rod is two sections of left and right, and left section of adjusting rod is light bar segment, and right section of adjusting rod is thread segment, and right section of adjusting rod is screwed into
State in the internal thread segment of blind hole, left section of light hole section of the above-mentioned blind hole of entrance of adjusting rod is interior and keeps gap to coordinate, it is left in adjusting rod
It is the annular groove 5a for being inverted isosceles trapezoid that there is a cross section at the middle part of section, and nut 6 is screwed on the external screw thread of right section of adjusting rod, will
Adjusting rod 5 is locked；There is a radial hole on the external cylindrical surface of piston 4, on the position of the radial hole and the light bar segment of adjusting rod 5
Annular groove 5a is corresponding and connects, and has 1~3 steel balls 8 in above-mentioned radial hole, and steel ball 8 coordinates with above-mentioned radial direction interporal lacuna,
The quantity of steel ball 8 meets following conditions：When following steel ball 8 enters annular groove 5a, the sphere of steel ball 8 above is not higher than work
The external cylindrical surface of plug 4；Microswitch 3 is fixed on actuator housing 1 by support 2, and the reed 3b of microswitch 3 is covered
State radial hole；When adjusting rod 5 is moved relative to piston 4, during by 8 jack-up of steel ball, upward jack-up reed 3b and then contact 3a is promoted
Trigger the state upset of microswitch 3.
Operation principle of the invention is：When hydraulic lock is unlocked, center-pole 7 produces relative displacement, the phase of steel ball 8 with piston 4
Annular groove 5a movements to adjusting rod 5, when steel ball 8 moves to the inclined-plane of annular groove 5a, steel ball 8 is in the radial hole of piston 4
Motion upwards, the state upset of upward jack-up reed 3b and then promotion contact 3a triggering microswitches 3, sends hydraulic lock unblock letter
Number.
When hydraulic lock is locked, the annular groove 5a of adjusting rod 5 returns to the axial location of radial hole, and steel ball 8 is in reed 3b bullets
Power effect is pushed down into radial hole, and microswitch contact 3a returns to home position, and microswitch resets, and is sent hydraulic lock and is resetted and believes
Number.
When hydraulic lock is locked, distance of the steel ball 8 apart from annular groove 5a inclined-planes is relevant with monitoring threshold：Center-pole 7 is relative
When piston 4 is to left movement, steel ball 8 is more remote apart from annular groove 5a right sides inclined-plane, the opposing pistons 4 of center-pole 7 that the jack-up of steel ball 8 needs
Displacement it is bigger, i.e., the monitoring threshold that the opposing pistons 4 of center-pole 7 occur to misplace to the left is bigger；The opposing pistons 4 of center-pole 7 to
During right motion, steel ball 8 is more remote apart from annular groove 5a left sides inclined-plane, the displacement of the opposing pistons 4 of center-pole 7 that the jack-up of steel ball 8 needs
Amount is bigger, i.e., the opposing pistons 4 of center-pole 7 occur bigger to the monitoring threshold of dextroposition.After nut 6 is unscrewed, can be by screw thread
Adjustment adjusting rod 5 is screwed into the depth of center-pole unthreaded hole, distance of the steel ball 8 apart from annular groove 5a right sides inclined-plane is adjusted, in can adjust
There is the monitoring threshold for misplacing to the left in the opposing pistons 4 of core bar 7；Distance of the steel ball 8 apart from annular groove 5a left sides inclined-plane is adjusted, it is adjustable
There is the monitoring threshold to dextroposition in the opposing pistons 4 of whole center-pole 7.
