The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention will be further described.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1
As shown in Figure 1, the direction of transfer of power is: the weight → worm gear reducer of whole jack-up unit → connection discharge mechanism → locking teeth stick → lifter rack.Bear by wedge pedestal 5 horizontal force that the tooth bar pressure angle produces in whole process, because whole platform gravity is constant and much larger than the horizontal force that produces, therefore the line of force here is only for the main bearing part that transmits gravity.Main bearing part in case platform needs release adjustment height on the fastening system line of force is because long-time heavy duty produces elastic deformation can't independently recover the time, and worm gear reducer 2 can't drive carrying screw rod 301 and retract, so occur can't release accident.For avoiding this kind phenomenon, the connection discharge mechanism is set.Carrying screw rod 301, wedge 304 and discharge mechanism are collectively referred to as the connection discharge mechanism, by worm gear reducer 2, drive the certain distance that can vertically move around, also can be in the position of adjusting its vertical direction when with the engaging tooth stick, being connected.The engaging tooth stick provides horizontal direction power by the engagement oil cylinder simultaneously, thereby can planar swing locking and the release that realizes fastening system with lifter rack engagement, disengaging engagement.Carrying screw rod 301 is connected by discharge mechanism with wedge 304 is middle, and discharge mechanism comprises unloading swivel plate 305 and unloading junction plate 306.The intermediate link that discharge mechanism transmits as the line of force, can not normally retract carrying screw rod 301 when platform suffers excessive load, and when fastening system can not normal release, it can fall the release of internal force between carrying screw rod 301 and wedge 304.
