Oil in body 211 flows between upper oil cavitie C1 and lower oil cavitie C2.
As shown in figures 2 a and 2b, when cylinder body 211 is in the 3rd position, and piston 212 drops to lowest order in cylinder body 211
When, magnetic valve 31 is closed, and therefore, the oil in upper oil cavitie C1 can not flow to lower oil cavitie C2 so that cylinder body 211 can not be relative to piston
212 motions.Now, the output shaft 411 of motor 41 is rotated with second direction causes leading screw 421 to rise, and piston 212 rises therewith,
And drive cylinder body 211 and outer tube 13 to rise to cylinder body 211 and return to first position, as best shown in figures 3 a and 3b.Wherein, second direction
It is opposite with first direction.Thus, connecting bridge lowering or hoisting gear recovers to normal condition as best shown in figures 3 a and 3b.
In the present embodiment, fast descending mechanism 20 also includes hinge retainer 24, and it includes first axle portion 241 and second hinge
Portion 242, the one end in first axle portion 241 and transition spool piece 23 are be hinged point articulated first, the one end in second hinge portion 242 with it is outer
Sleeve pipe 13 is be hinged point articulated second, and the other end and the other end in second hinge portion 242 in first axle portion 241 are hinged, and first
The diameter parallel of hinge and the second hinge.
Moment of torsion caused by motor 41 is first delivered to transition spool piece 23, then is transmitted from transition spool piece 23 via hinge retainer 24
Onto outer tube 13.Inner sleeve 12, outer tube 13 and transition spool piece 23 are shape identical polygon, outer tube 13 and transition sleeve
Every side of pipe 23 is equipped with a hinge retainer 24.Because inner sleeve 12 is fixed, therefore outer tube 13 is not
It can rotate, hinge retainer 24 can prevent motor 41 and transition spool piece 23 from unnecessary rotation occurs, and play the work of rotation stop
With.Meanwhile hinge retainer 24 can also prevent from glancing off between transition spool piece 23 and outer tube 13, keep position between the two
Put relation.

On oil circuit L1.Power unit 50 includes fuel tank 51, filter 52, hydraulic pump 53, the overflow valve 55 of check valve 54 and second；Work as hydraulic pressure
When pump 53 works, the hydraulic oil in fuel tank 51 can be pressed into the upper oil cavitie C1 of hydraulic cylinder 21, while the oil in lower oil cavitie C2
It is back in fuel tank 51, piston 212 drops to lowest order in cylinder body 211, i.e., fast descending mechanism 20 returns to initial position.
In addition, in the present embodiment, controlling organization 30 may also include travel switch 35, and it is arranged at the outer wall of transition spool piece 23 such as
Shown in Fig. 3 a and Fig. 3 b, when cylinder body 211 is in first position, travel switch 35 is not triggered；When the piston 212 of hydraulic cylinder 21
Not in the lowest order of cylinder body 211, travel switch 35 is triggered, so as to judge whether Boarding bridge access 14 carries out fast drop action.
That is, if travel switch 35 is triggered, staff's Boarding bridge access 14 is notified to carry out fast drop action, staff's control is stepped on
Machine bridge lowering or hoisting gear carries out follow-up normal lifting action, makes it restore to normal condition.
In summary, connecting bridge lowering or hoisting gear of the invention is by the oil circuit of solenoid valve control hydraulic cylinder, in normal condition
Under, the oil in upper oil cavitie is spacing by cylinder body, the cylinder body of hydraulic cylinder and outer tube is held in higher position, works as controlling organization
When being connected to signal needs fast drop, magnetic valve is opened, it is allowed to which oil flows between upper and lower cavity, so as to release the limit for cylinder body
Position, under connecting bridge Gravitative Loads, the cylinder body of outer tube and hydraulic cylinder is driven to decline, so as to complete the rapid decrease of connecting bridge.
Therefore, only leading screw is driven to slide by motor with existing, so as to which the elevating mechanism for driving outer tube, connecting bridge to decline is compared,
The present invention is declined by magnetic valve quick response to be instructed, and cylinder body declines immediately while magnetic valve is opened, outer tube and connecting bridge
Synchronous therewith to decline, it is short that whole process reacts the fast used time, connecting bridge rapid decrease immediately before contact with hatch door, so as to avoiding and
Hatch door contacts, and prevents that hatch door collision is impaired.Therefore, connecting bridge lowering or hoisting gear of the invention can be effectively protected hatch door.
