Abstract
The present invention relates to a kind of a kind of spiral being convenient to connect pile body and basic module and pierce formula stake automatic connecting mechanism, comprise pile crown and the sleeve pipe being fixed on basic module top, pile crown comprises pile crown intubate, lock core slip pipe, lock core and spring, radially fixed lock core slip pipe in the middle part of pile crown intubate, spring loads lock core slider tube, both ends of the spring connects lock core, and lock core outer face comprises one section of inclined-plane; Casing wall has lock slots.Pierce in process, lock core retracts to lock core slider tube in the extruding being subject to basic module internal surface of sleeve pipe, and during to desired depth, lock core ejects in lock slots position and blocks sleeve pipe in lock core slip pipe, thus completes certainly being dynamically connected of pile body and basic module.The present invention adopts a rim lock cylinder mechanism, and be dynamically connected pile body and basic module certainly, decreases artificial construction's amount, improves efficiency of construction and working security, can also reduce cost of labor.
Description
Technical field
The spiral that the present invention relates to subaqueous construction pierces formula pile crown, is the bindiny mechanism that spiral pierces formula pile body and basic module.
Background technology
The main form of construction work that current spiral pierces formula stake provides moment of torsion by construction machinery on stake top, and pile body is pierced the soil body, and the method is convenient and easy.But under water in work progress, generally need manually to go to be connected with basic module pile body, difficulty of construction is comparatively large and efficiency low cost is high.Therefore a kind of novel mechanism is needed to solve the problem.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of spiral being convenient to connect pile body and basic module and pierces formula stake automatic connecting mechanism.
For solving the problems of the technologies described above, the present invention by the following technical solutions.
A kind of spiral pierces formula stake automatic connecting mechanism, comprises pile crown and the sleeve pipe being fixed on basic module top,
Described pile crown comprises pile crown intubate, lock core slip pipe, lock core and spring, radially fixed lock core slip pipe in the middle part of pile crown intubate, and spring loads lock core slider tube, and both ends of the spring connects lock core, and lock core outer face comprises one section of inclined-plane;
Described casing wall has lock slots.
During construction, pile crown provided by the invention and screw pile are connected, then is connected with construction machinery.After having connected, after single stake Underwater Navigation, pierce.The casing wall of basic module reserves lock slots according to desired depth, when being about to be drilled to desired depth, pile crown inserts in sleeve pipe, the extruding that lock core is subject to basic module internal surface of sleeve pipe retracts to lock core slider tube, and during to desired depth, pile crown intubate contacts with basic module, basic module prevents screw pile to continue downwards, in original place idle running, pile crown can treat that lock core forwards lock slots position to, lock core ejects and blocks casing wall in lock core slip pipe, thus completes certainly being dynamically connected of pile body and basic module.
As the preferred scheme of one, lock core comprises connector and is fixed on the bevelled cylinder of outer face tool outside this connector.
As the preferred scheme of another kind, pile crown cannula outer wall is provided with protruding limiting stand.
The present invention is by the rim lock cylinder mechanism on pile crown and the sleeve pipe on basic module, and be dynamically connected pile body and basic module certainly, decreases artificial construction's amount, improves efficiency of construction and working security, can also reduce cost of labor.

Detailed description of the invention
In order to make those skilled in the art better understand the present invention, below in conjunction with accompanying drawing, explanation clear, complete is further done to the present invention.
As shown in Figure 1, a kind of spiral of the present invention pierces formula stake automatic connecting mechanism, comprise pile crown and the sleeve pipe 2 being fixed on basic module 1 top, described pile crown comprises pile crown intubate 3, lock core slip pipe 4, lock core 5 and spring 6, radially fixed lock core slip pipe 4 in the middle part of pile crown intubate 3, it is inner that spring 6 loads lock core slip pipe 4, and spring 6 two ends connect lock core 5, and lock core 5 outer face comprises one section of inclined-plane; Described sleeve pipe 2 wall has lock slots 7.
During making, first two lock cores 5 are connected to spring 6 two ends, are then inserted in lock core slip pipe 4, in the symmetric position of pile crown intubate 3 wall, perforate arranges locating slot, after lock core slip pipe 4 being placed in intubate is decided at the higher level but not officially announced and being positioned at locating slot, is welded and fixed.Pile crown intubate 3 bottom and screw pile 11 are welded to connect, and pile crown intubate 3 top is provided with the linkage section be connected with construction machinery.
As shown in Figure 3, lock core 5 comprises connector 8 and the bevelled cylinder 9 of outer face tool be fixed on outside this connector 8 further.Wherein, connector 8 can be set to cylinder or other cylinder that radius is greater than outside cylinder, and its effect is linking springs, and restriction lock core only slides in slip pipe.The inclined-plane of lock core 5 front end can make lock core 5 successfully pressurized to retract to lock core slip pipe 4 inner, after lock core 5 snaps in the lock slots 7 of sleeve pipe 2, the top edge of lock slots 7 is blocked in the outer upper end face of lock core 5.
As shown in Figure 2, pile crown intubate 3 outer wall is provided with protruding limiting stand 10 further, and during to desired depth, the limiting stand 10 in pile crown intubate 3 contacts with basic module 1, and basic module 1 prevents screw pile 11 to continue downwards.
Sleeve pipe 2 wall is reserved with lock slots 7 according to desired depth.By location work ship, basic module 1 is positioned precalculated position under water.Pierce in process, after pile crown intubate 3 enters sleeve pipe 2, lock core 5 is subject to the extruding of sleeve pipe 2 inwall, retracts to lock core slip pipe 4 inner.As shown in Figure 2, during to desired depth, limiting stand 10 in pile crown intubate 3 contacts with basic module 1, basic module 1 prevents screw pile 11 to continue downwards, pile crown can dally in original place, when lock core 5 forwards in lock slots position, lock core 5 ejects and blocks casing wall in lock core slip pipe 4, thus completes certainly being dynamically connected of pile body and basic module 1.
The scope of protection of present invention is not limited to above detailed description of the invention; to those skilled in the art; the present invention can have various deformation and change, all in design of the present invention and any amendment, the improvement done within principle be equal to replacement and all should be included within protection scope of the present invention.
