Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, 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, be 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 → connection discharge mechanism → locking teeth stick → lifter rack of whole jack-up unit.Bear by wedge pedestal 5 horizontal force that tooth bar pressure angle produces, because whole platform gravity is constant and much larger than the horizontal force produced, therefore the line of force is here only for the main bearing part transmitting gravity in whole process.Need to unlock 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 once platform, worm gear reducer 2 cannot drive carrying screw rod 301 to retract, and then the accident that cannot unlock occurs.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, drive by worm gear reducer 2 certain distance that can vertically move around, and also can adjust the position of its vertical direction when being connected with band engaging tooth stick.Engaging tooth stick simultaneously provides horizontal direction power by engagement oil cylinder, can planar swing engage with lifter rack, depart from and engage thus realize locking and the unblock of fastening system.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, when platform suffers excessive load to make carrying screw rod 301 normally not retract, fastening system can not normal release time, it can by carrying screw rod 301 and wedge 304 between release of internal force fall.
As shown in Figures 2 to 5, discharge mechanism is provided with between described carrying screw rod 301 and described wedge 304, described discharge mechanism comprises unloading swivel plate 305 and unloading junction plate 306, be provided with carrying screw rod back-up ring 302 in the end of described carrying screw rod 301, described unloading swivel plate 305 is connected with described carrying screw rod 301 by described carrying screw rod back-up ring 302; Described wedge 304 is provided with wedge block 303, and described unloading junction plate 306 is connected with described wedge 304 by described wedge block 303; Described unloading junction plate 306 is provided with groove, described unloading swivel plate 305 is provided with the projection corresponding with described groove, filler is equipped with between described projection and described groove, described filler can be paraffin, pottery, river sand, diamond dust, manganese sand or quartz sand, the present embodiment is preferably quartz sand, quartz sand 308 is pressed with cover plate 307, and the thickness that quartz sand is laid is 8mm; In the both sides that described unloading junction plate 306 is relative, a pair tapped through hole 309 is all set.
The using method of connection discharge mechanism of the present invention is, the first step, lays 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 loosen and be washed away by from described groove, make to reserve gap between described unloading swivel plate 305 and described unloading junction plate 306.At this moment making the elastic deformation of each main bearing part be recovered and eliminate associated residual stress by reserving gap, making fastening system can normal release.
Unloading junction plate 306 as shown in Figure 6 to 8, described unloading junction plate 306 is provided with groove, all arranges a pair tapped through hole 309, two double thread through hole 309 be communicated with described groove in the both sides that described unloading junction plate 306 is relative.
