Abstract
The invention relates to an automatic connecting mechanism for a spirally drilling-in type pile. The automatic connecting mechanism is beneficial to connection between a pile body and a base module and comprises a pile head and a sleeve fixed on upper portion of the base module. The pile head comprises a pile head insert pipe, a lock cylinder slide pipe, a lock cylinder and a spring; the lock cylinder slide pipe is fixed in the middle of the pile head insert pipe in the radial direction, the spring is installed in the lock cylinder slide pipe, the two ends of the spring are connected with the lock cylinder, and the outer end face of the lock cylinder comprises a section of slope. A locking groove is formed in the wall of the sleeve. In the drilling-in process, the lock cylinder retracts into the lock cylinder slide pipe after being extruded by the inner wall of the sleeve of the base module, when arriving at a preset depth, the lock cylinder is popped from the locking groove through the lock cylinder slide pipe to clamp the sleeve, and therefore the automatic connection between the pipe body and the base module is achieved. According to the automatic connecting mechanism, the pile body and the base module are automatically connected by adopting one spring lock cylinder mechanism, so that manual construction workload is reduced, construction efficiency is enhanced, construction safety is improved, and labor cost can also be lowered.
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 is on stake top, to provide moment of torsion by construction machinery, and pile body is pierced to the soil body, and the method is convenient and easy.But in work progress, generally need manually to go pile body to be connected with basic module under water, difficulty of construction is large and efficiency is low-cost high.Therefore need a kind of novel mechanism to address the above problem.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of spiral of 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.
Spiral pierces a formula stake automatic connecting mechanism, comprises pile crown and the sleeve pipe that is fixed on basic module top,
Described pile crown comprises pile crown intubate, lock core slip pipe, lock core and spring, and pile crown intubate middle part is fixed lock core slip pipe radially, and it is inner that spring packs lock core slip pipe into, and both ends of the spring connects lock core, and lock core outer face comprises one section of inclined-plane;
On described casing wall, have lock slots.
During construction, pile crown provided by the invention and screw pile are connected, then be connected with construction machinery.After having connected, single stake pierces after locating under water.On the casing wall of basic module, according to desired depth, reserve lock slots, when being about to be drilled to desired depth, pile crown inserts in sleeve pipe, and the extruding that lock core is subject to basic module internal surface of sleeve pipe retracts to lock core slip pipe inside, during to desired depth, pile crown intubate contacts with basic module, and basic module has stoped screw pile to continue downwards, and pile crown can treat that lock core forwards lock slots position in original place idle running, lock core is from ejecting and block casing wall in lock core slip pipe, thereby completes being certainly dynamically connected of pile body and basic module.
As a kind of preferred scheme, lock core comprises connector and is fixed on the bevelled cylinder of outer face tool in this connector outside.
As the preferred scheme of another kind, pile crown intubate 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 certainly dynamically connected pile body and basic module, reduced artificial construction's amount, improved efficiency of construction and working security, can also reduce cost of labor.

Fig. 3 is the structural representation of lock core
In figure, 1-basic module, 2-sleeve pipe, 3-pile crown intubate, 4-lock core slip pipe, 5-lock core, 6-spring, 7-lock slots, 8-connector, 9-cylinder, 10-limiting stand, 11-screw pile.
The specific embodiment
In order to make those skilled in the art better understand the present invention, below in conjunction with accompanying drawing, the present invention is done to further clear, complete explanation.
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 that is 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, pile crown intubate 3 middle parts are fixed lock core slip pipe 4 radially, spring 6 packs lock core slip pipe 4 inside into, and spring 6 two ends connect lock core 5, and lock core 5 outer faces comprise one section of inclined-plane; On described sleeve pipe 2 walls, have lock slots 7.
During making, first two lock cores 5 are connected in to spring 6 two ends, are then inserted in lock core slip pipe 4, in the symmetric position of pile crown intubate 3 walls, perforate arranges locating slot, and lock core slip pipe 4 is placed in intubate and is positioned, after locating slot, to be welded and fixed.Pile crown intubate 3 bottoms and screw pile 11 are welded to connect, and pile crown intubate 3 tops are provided with the linkage section being connected with construction machinery.
As shown in Figure 3, lock core 5 comprises connector 8 and the bevelled cylinder 9 of outer face tool that is fixed on these connector 8 outsides 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 ends can make lock core 5 successfully pressurized retract to lock core slip pipe 4 inside, when lock core 5 snaps in after the lock slots 7 of sleeve pipe 2, the outer upper end face of lock core 5 blocks the top edge of lock slots 7.
As shown in Figure 2, pile crown intubate 3 outer walls are 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 has stoped screw pile 11 to continue downwards.
On sleeve pipe 2 walls, according to desired depth, be reserved with lock slots 7.By location work ship, basic module 1 is positioned to precalculated position under water.Pierce in process, when pile crown intubate 3 enters after sleeve pipe 2, lock core 5 is subject to the extruding of sleeve pipe 2 inwalls, retracts to lock core slip pipe 4 inside.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 has stoped screw pile 11 to continue downwards, pile crown can dally in original place,, until lock core, forward 5 to during in lock slots position, lock core 5 blocks casing wall from the interior ejection of lock core slip pipe 4, thereby completes being certainly dynamically connected of pile body and basic module 1.
The scope of protection of present invention is not limited to the above specific embodiment; to those skilled in the art; the present invention can have various deformation and change, all any modifications of doing within design of the present invention and principle, improves and is equal within replacement all should be included in protection scope of the present invention.
