The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described further.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
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.In whole process, by wedge pedestal 5, bear the horizontal force that tooth bar pressure angle produces, because whole platform gravity is constant and much larger than the horizontal force producing, therefore the line of force is here only for the main bearing part that transmits gravity.Once platform need release adjustment height and main bearing part in the fastening system line of force because long-time heavy duty produces elastic deformation and cannot independently recover, worm gear reducer 2 cannot drive carrying screw rod 301 to retract, so occur cannot release accident.For avoiding this kind of phenomenon, connection discharge mechanism is set.Carrying screw rod 301, wedge 304 and discharge mechanism are collectively referred to as 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 being connected with engaging tooth stick.Engaging tooth stick provides horizontal direction power by 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 in the middle of wedge 304, 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 when platform suffers excessive load to make to carry screw rod 301, and when fastening system can not normal release, it can fall the release of internal force between carrying screw rod 301 and wedge 304.
As shown in Figures 2 to 5, between described carrying screw rod 301 and described wedge 304, be provided with discharge mechanism, described discharge mechanism comprises unloading swivel plate 305 and unloading junction plate 306, in the end of described carrying screw rod 301, be provided with carrying screw rod back-up ring 302, described unloading swivel plate 305 is connected with described carrying screw rod 301 by described carrying screw rod back-up ring 302; On described wedge 304, be provided with wedge block 303, described unloading junction plate 306 is connected with described wedge 304 by described wedge block 303; On described unloading junction plate 306, be provided with groove, on described unloading swivel plate 305, be provided with the projection corresponding with described groove, between described projection and described groove, be equipped with filler, described filler can be paraffin, pottery, river sand, diamond dust, manganese sand or quartz sand, the present embodiment is preferably quartz sand, on quartz sand 308, be pressed with cover plate 307, the thickness that quartz sand is laid is 8mm; In the relative both sides of described unloading junction plate 306, a pair of tapped through hole 309 is all set.
The using method of connection discharge mechanism of the present utility model is that the first step is laid one deck quartz sand 308 in described groove, blocks tapped through hole 309 when system is in running order; Second step, when described carrying screw rod 301 cannot be retracted, opening tapped through hole 309 uses giant to wash by water in described tapped through hole 309, make that one deck quartz sand 308 become flexible and be washed away from described groove, make to reserve gap between described unloading swivel plate 305 and described unloading junction plate 306.At this moment by reserving gap, make the elastic deformation of each main bearing part be replied and eliminate relevant residual stress, make the fastening system can normal release.
Unloading junction plate 306 as shown in Figure 6 to 8, is provided with groove on described unloading junction plate 306, a pair of tapped through hole 309, two double thread through holes 309 is all set in the relative both sides of described unloading junction plate 306 and is communicated with described groove.
