The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1 to accompanying drawing 4; The described pile leg locking device of present embodiment with the high-voltage oil cylinder release; It includes seat assembly 4 behind seat assembly 2 behind top drive assembly 1, the top voussoir, side direction pull action cylinder assembly 3, the bottom voussoir, pile leg locking piece 5, erection device assembly 6, bottom drive assembly 7; Wherein, Described top drive assembly 1 and bottom drive assembly 7 correspondences are installed in the upper and lower position of hull; And the pile leg locking piece 5 through tooth bar 15 both sides of climbing on the top voussoir that carries 8 and bottom voussoir 9 and the spud leg matches and acts on this tooth bar 15 that climbs respectively; Simultaneously correspondingly on hull the side direction pull action cylinder assembly 3 that acts on pile leg locking piece 5 is installed and corresponding pile leg locking piece 5 is led and spacing fixing erection device assembly 6; Make pile leg locking piece 5 to be meshed with the tooth bar 15 that climbs or to break away from through the side direction pull action cylinder assembly 3 and the acting in conjunction of bottom drive assembly 7, above-mentioned each top voussoir 8 and bottom voussoir 9 are led by seat assembly 4 behind seat assembly 2 behind the top voussoir of a side separately and the bottom voussoir respectively.In releasing process; Because the platform weight long-time bearing is on locking device; Cause easily release of locking device; To this situation; The top drive assembly 1 of this locking device is designed to include top oil cylinder 10, the top voussoir 8 that is fixedly connected with the piston rod of this top oil cylinder 10 and the worm and gear drive assembly 11 that cooperatively interacts with this top voussoir 8, and wherein, described worm and gear drive assembly 11 is mainly by worm gear 12, worm screw 13 and drive this worm gear 12 and the hydraulic motor 14 of worm screw 13 actions is formed.Such design makes that the effect of oil cylinder 10 drives top voussoir 8 knee-actions through the top, and hydraulic motor 4 can drive worm gear 12 and follow 8 actions of top voussoir with worm screw 13.In the locking process; After this locking device each several part was accomplished the locking basic operation, top oil cylinder 10 carried out high pressure and loads, and platform is promoted certain altitude; Worm and gear drive assembly 11 is followed with top voussoir 8 and is adjacent to; This moment, jacking system was in Light Condition, and platform weight all is transferred on this locking device, increased the safety of platform.And in releasing process; Top oil cylinder 10 carries out high pressure and loads; Make top voussoir 8 and worm and gear drive assembly 11 produce certain clearance, accomplish the release basic operation again, platform weight is born by top oil cylinder 10 earlier during here because of release; 11 needs of worm and gear drive assembly overcome self resistance just can be realized easily moving, and has avoided occurring the stuck phenomenon of worm gear 12 and worm screw 13.In addition; Because the described erection device assembly of the utility model 6 is mainly by being installed in baffle plate 16 on the hull, being installed in the lock pin oil cylinder 17 on this baffle plate 16 and driving flexible lock pin 18 by this lock pin oil cylinder 17 and form; Such design makes the utility model to drive lock pin 18 through lock pin oil cylinder 17 and to carry out freely stretching according to the needs of locking or release action, realizes guiding and the position-limiting action of pile leg locking piece 5 in locking or releasing process; Make pile leg locking piece 5 locking or releasing process in stable action; Can prevent pile leg locking piece 5 run-off the straight phenomenons effectively, and release is stretched out lock pin 18 through lock pin oil cylinder 17 after finishing, can be exactly that pile leg locking piece 5 is fixing; Increase its reliability, satisfy job requirements.Below be the locking action of the utility model and the detailed process of release action: during locking action, the lock pin oil cylinder 17 of erection device assembly 6 at first moves, and drives lock pin 18 withdrawals; Let pile leg locking piece 5 be in free state, at this moment, pile leg locking piece 5 begins to press to the tooth bar 15 that climbs under the effect of side direction pull action cylinder assembly 3; When pile leg locking piece 5 fully with after the tooth bar 15 that climbs is meshed, bottom drive assembly 7 begins action, drives its bottom voussoir 9 risings; Simultaneously its bottom voussoir 9 by the bottom voussoir after seat assembly 4 lead, seat assembly 4 contacts with pile leg locking piece 5 behind the voussoir of bottom, when the bottom of bottom drive assembly 7 voussoir 9 complete in after pile leg locking piece 5 contacts; Top drive assembly 1 begins action at this moment, and its top oil cylinder 10 carries out high pressure and loads, and drives its top voussoir 8 and descends; Simultaneously its top voussoir 8 by the top voussoir after seat assembly 2 lead, seat assembly 2 contacts with pile leg locking piece 5 behind the voussoir of top, and is complete in after pile leg locking piece 5 contacts until top voussoir 8; The worm and gear drive assembly 11 of top drive assembly 1 is followed with top voussoir 8 and is adjacent to; Top voussoir 8 is worked to add press fit, top oil cylinder 10 releases this moment, the locking action of completion the utility model; Accomplishing rear platform weight in locking will be delivered on the locking device by jacking system, make platform more safe and reliable; During the release action, top drive assembly 1 at first moves, and its top oil cylinder 10 carries out high pressure and loads; Drive top voussoir 8 decline certain distances, make top voussoir 8 and worm and gear drive assembly 11 have certain clearance, get on thereby make the platform weight of bearing by worm and gear drive assembly 11 originally transfer to top oil cylinder 10; This moment, the worm and gear drive assembly 11 began action, just can easily be returned to the origin-location through overcoming self resistance, behind worm and gear drive assembly 11 complete rollbacks; Oil cylinder 10 releases in top drive top voussoir 8 seat assembly 2 behind the voussoir of top and break away from pile leg locking piece 5, after top voussoir 8 breaks away from pile leg locking piece 5 fully; Bottom drive assembly 7 begins action, drives its bottom voussoir 9 and descends, after bottom voussoir 9 breaks away from pile leg locking piece 5 fully; Pile leg locking piece 5 begins to break away from the tooth bar 15 that climbs under the effect of side direction pull action cylinder assembly 3; Pile leg locking piece 5 after the disengaging fixes pile leg locking piece 5 after the lock pin 18 that the lock pin oil cylinder 17 of erection device assembly 6 drives this erection device assembly 6 stretches out, prevents its downslide; Completion release action, the weight of platform will be born by jacking system this moment.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
