The lower end of bolt 42 is less than the upper edge of the end plate 2.
In embodiment, 31 periphery of slide cartridge is arranged at intervals with lateral gilled rings 35.
In embodiment, 31 upper edge radial direction of slide cartridge is provided with vertical floor 36.
The lateral gilled rings 35 of setting and vertical floor 36 can increase the overall stiffness of slide cartridge 31, and slide cartridge 31 is made to hang a process
In have preferably withstand forces.
In embodiment, main 32 place straight line of lifting lug and the 33 place straight line of secondary suspension ring are perpendicular.
Symmetrically arranged main lifting lug 32 makes during hanging stake, and prefabricated pile can keep vertical state；And symmetrically arranged pair
Hanging ring 33 when lifting by crane slide cartridge device using two secondary suspension rings 33, can ensure the balance of slide cartridge device.
In embodiment, the section of stress gusset 41 is in " II " character form structure.Such structure can improve stress gusset 41
Rigidity and bending resistance, shearing strength, while again can alleviator dead weight.
In embodiment, stress gusset 41 is fixed by high-strength bolt 43 and the tensioning hole 2a phases of the end plate 2.
Anticollision round 41a is set, limiting device is enable to be suitable for the prefabricated pile of different wall thickness；When stress gusset 41 passes through
High-strength bolt 43 is fixed on the tensioning hole 2a of end plate 2, and (anticollision bolt 42 is located at pre- in the suitable holes of anticollision round 41a
Within the inner wall of stake processed) install anticollision bolt 42 after, when stress gusset 41 receives shock, anticollision bolt 42 can limit stress
The rotation of gusset 41 so as to which the top of slide cartridge 31 is stretched on the interior edge for ensureing stress gusset 41, and then ensures during hanging stake, slide cartridge
Device will not be detached from from prefabricated pile.
In embodiment, the both sides of the mounting hole of stress gusset 41 are respectively arranged with deep floor 44.Deep floor 44 is set,
The intensity of stress gusset 41 can be further improved.
In embodiment, the number of stress gusset 41 is three pieces, and three pieces of stress gussets 41 are uniformly distributed on periphery.
4 idler wheels 34 on slide cartridge 31 are also uniformly distributed on periphery.
A kind of hanging method of safety jaw stake device, includes the following steps：
Step 1: the installation of slide cartridge device：Slide cartridge 31 is sling using secondary suspension ring 33 using the hook of loop wheel machine, and by slide cartridge
31 are inserted in prefabricated stake body 1, and slide cartridge device unclamps the suspension hook in secondary suspension ring 33 after installation is complete；
When slide cartridge device is installed, the use of secondary suspension ring 33 is selected according to the placement state of prefabricated pile to be hung：When prefabricated pile is put down
When lying, a secondary suspension ring 33 only is caught on hook, and when prefabricated pile is upright, corresponding pair need to be caught on respectively with two hooks hang
Ring 33, so as to enable worker that slide cartridge 31 easily is inserted in prefabricated pile.
Step 2: the installation of limiting device：Stress gusset 41 is fixed on the tensioning hole 2a of end plate 2, and is arranged in anticollision
Anticollision bolt 42 is loaded onto on the 41a of hole；Anticollision bolt 42 is installed in anticollision round 41a near the one of prefabricated 1 inner wall of stake body
In a mounting hole；
The installation number of stress gusset 41 is depending on the factors such as diameter, the dead weight of prefabricated pile, installation process, stress gusset
41 are uniformly arranged the evenness to ensure stress.
Step 3: hang stake, pile extension：Crane is hung over can carry out hanging stake on the main lifting lug 32 of a pair of slide cartridge 31, will
After prefabricated pile is hung to designated position, pile extension can be carried out；Since main lifting lug 32 is symmetrical arranged, during hanging stake, both sides
Main 32 uniform stressed of lifting lug, to ensure that prefabricated pile in vertical state, is conducive to follow-up pile extension, the progress for planting stake operation, hangs in this way
During stake, slide cartridge device moves to the upper end of prefabricated pile along pile body, and offsets with limiting device.
Step 4: upright stake is broken off relations：A upper section stake carries out quadrangle electric welding with next section stake and fixes, by loop wheel machine slightly way roller
Side oscillation, suspension hook plumb line are placed on the outside of prefabricated pile, and the suspension hook for the loop wheel machine that then slowly lands, slide cartridge device is under the action of dead weight
It can glide therewith, slide cartridge device is slipped to by prefabricated pile upper end on workbench, prefabricated pile is clamped with clip pile device, by worker
Decoupling device and pile extension welding are completed on workbench；When slide cartridge device moves, the outer wall of idler wheel 34 and prefabricated pile, which rolls, to be coordinated, both
The abrasion of device is reduced, slide cartridge 31 is also avoided and tilts and block.
Step 5: secondary hook hangs stake：After the completion of pile extension welding, loop wheel machine is transferred by principal arm by suberect prefabricated pile, is hung
Slide cartridge 31 (when at this time suspension hook orientation should with break off relations consistent) of the hook on prefabricated pile, manually completes hook on workbench,
Slide cartridge device along prefabricated pile is risen to and is offseted stress with limiting device, clip pile device is unclamped, plant stake is carried out, when prefabricated pile is sunk to
During predetermined altitude, prefabricated pile is clamped fixation by clip pile device, after removing limiting device using portable impact gun electric drill, will be pacified with loop wheel machine
Dress slide cartridge is hung out from the upper end of prefabricated pile.
It once hangs an operation change in this way to complete, the slide cartridge device and limiting device of dismounting are transferred to Material Staging Area, carry out down
Once hang stake；During the entire process of above-mentioned, working at height is avoided, operation intensity is reduced, eliminates safe hidden trouble, improves comprehensive work
Make efficiency；Equipment attrition also greatly reduces, and can effectively reduce construction cost.
Highly preferred embodiment of the present invention has been elucidated with, and the various change or remodeling made by those of ordinary skill in the art are all
It is without departing from the scope of the invention.
