B. hoist engine continues unloaded the rotation, up to suspension hook reach press down the position of fastening pipe rope 17 till.
C. the operative employee is hand-manipulated, suspension hook 13 is hooked in to press down fastens on the pipe rope 17.
D. start hoist engine, change hoist engine and turn to, make electric controlled hoist rolling wire rope, running block 12 rises, and suspension hook 13 pullings press down fastens pipe rope 17, presses down to fasten pipe rope 17 and press down through angle pulley 18 traction retaining wall pipes; Make the retaining wall mouth of pipe insert the soil certain depth at place, stake position.
E. hammer ram punching continues to press down the retaining wall pipe to projected depth.Enlarged footing part at the bottom of the compaction pile, fluid concrete.
F. start electric controlled hoist once more; The operative employee changes hoist engine 16 reel direction of rotation through handling cam controller, makes reel emit wire rope once more; Pinnacled once more running block 12 is fallen because of the deadweight effect of retaining wall guard system; And and then make pressing down on the suspension hook 13 fasten that pipe rope 17 is lax to fall, reach suspension hook thus and press down the purpose (in case of necessity, the artificial cooperation breaks off relations) of fastening the pipe rope and breaking away from.
G. hoist engine continues unloaded the rotation, up to suspension hook reach tie up on the retaining wall pipe on carry the position of fastening pipe rope 14 till.
H. the operative employee is hand-manipulated, suspension hook 13 is hooked in to carry fastens on the pipe rope 14.
J. change electric controlled hoist and turn to, start hoist engine, hoist engine rolling wire rope rises the running block 12 that is in low level, and the suspension hook hook to carry and fastened pipe rope 14 and draw the retaining wall pipe and do to propose motion; The retaining wall pipe is mentioned certain altitude on continuing, and normally the lower end mouth of pipe of retaining wall pipe is lifted from the ground certain height.Accomplish the construction working of a foundation pile with this.Can do the preparation that pile driver moves this moment.
This shows that traditional Drop hammer pile driver retaining wall pipe running job process is more loaded down with trivial details.

The rammer of the utility model expands pile driver retaining wall pipe tandem trailer system, is connected into a system with carrying trailer system on the retaining wall pipe and pressing down the trailer system transformation, has mainly taked three modification measures.
(1) movable pulley, fixed pulley and directive wheel are reset, installed.
Shown in accompanying drawing 3, the utility model has been cancelled carrying fastening the pipe rope and pressing down on traditional and has been fastened the pipe rope, overlaps independently pulley system respectively to the lifting of retaining wall pipe with press down with 2.(1, be installed in the fixed pulley group of the lifting retaining wall pipe on the head piece; 2, be installed in the fixed pulley group that presses down the retaining wall pipe on the platform chassis; 3, be fixedly mounted on the lifting running block of retaining wall pipe upper end and press down running block.) and can make the up-down of the mobile drive retaining wall pipe of movable pulley.Because 2 groups of running block mutual alignments immobilize, thereby form the series system of 2 groups of trailer systems.Promptly be one of characteristics of this patent title; This is one of implication of series system; In addition, reel divides two districts, but rotates simultaneously, make wire rope one receive one and put, this be series system implication two; In addition, 4 cover fixed pulley groups and running block all adopt the distributing mounting means, guarantee the active force left and right sides balance of every group of assembly pulley to the retaining wall pipe.Be specially four movable pulley be installed on the retaining wall pipe, wherein two (pulley K and drive pulley P) on carry movable pulley, two (pulley C and pulley F) are for pressing down movable pulley in addition.Be installed on the crossbeam carrying fixed pulley (pulley M and pulley N) on two, two press down fixed pulley (pulley D and pulley E) and are installed on the platform chassis.In addition, two hoist engine directive wheels (pulley A and pulley J) also are installed on the crossbeam, and a directive wheel (pulley B) also is installed on the platform chassis.
(2) the electric controlled hoist reel is transformed.
Shown in accompanying drawing 3, the utility model is divided into two lifting drum with dividing plate, on one side for reel presses down the I district, on one side for carrying the II district on the reel.Reel presses down carries the II district respectively around steel cable on I district and the reel, and around on the contrary.Like this; When reel press down the I district press down wire rope by the rolling coiling time; Carry on the reel II district on carry wire rope and then be in by the state of emitting; Press down wire rope this moment through being installed in directive wheel A on the crossbeam, being installed in the directive wheel B on the platform chassis and pressing down fixed pulley D, press down fixed pulley E, being installed in pressing down movable pulley C and pressing down movable pulley F on the retaining wall pipe; With retaining wall pipe traction operation downwards, the trend that presses down wire rope is: reel presses down I district → directive wheel A → directive wheel B → press down movable pulley C → press down fixed pulley D → press down fixed pulley E → press down movable pulley F → directive wheel G → directive wheel H ..., (annotate: actual when pressing down the retaining wall pipe; Wire rope does not have motion at the G place, the G place is equivalent to the fixed end of wire rope).And this moment, on carry wire rope and then be in the state (also being the state that reel is initiatively emitted simultaneously) that come out by retaining wall pipe tractive from the lifting drum.
Otherwise; When lifting drum turns to change; What reel pressed down the I district presses down wire rope by being emitted from reel, carry on the reel II district on carry wire rope then by the reel rolling, at this moment; On carry wire rope through be installed on the crossbeam on carry directive wheel J, on carry fixed pulley M, on carry fixed pulley N and be installed on the retaining wall pipe on carry movable pulley K and on carry movable pulley P, with upwards operation of retaining wall pipe traction; Press down wire rope and then moved by retaining wall pipe tractive this moment.
(3) the hoist engine wire rope is not held the counterweight tensioning apparatus.
Being divided into two of electric controlled hoist; Reel press down carry on I district, the reel II district be linked together, drum diameter is identical, rotating speed is also identical; But reel presses down the number of plies that the wire rope of carrying the II district on I district, the reel rolls up in the most of time of work, and the number of plies is not necessarily identical.For example: a certain period, possible reel press down the I district wire rope roll two-layer, and carry on the reel II district wire rope roll one deck; At this moment, press down the every rolling of wire rope (or whenever emitting) once the rope capacity of circle with on carry wire rope whenever to emit the rope capacity that (or every rolling) enclose unequal, when reel turns around; The long difference of the rope in two districts is d π (d is a wirerope diameter); Because the existence of this difference is arranged, this just must influence the quality that wire rope twines, and makes one of them wire rope of emitting the district can be in relaxed state; To this situation, we are provided with roller steel wire rope strainer.As shown in Figure 3.
Press down constituting of wire rope strainer: directive wheel G and directive wheel H, orifice plate bearing I, end clamping plate I and bar-shaped counter weight I.
On carry constituting of wire rope strainer: directive wheel R, orifice plate bearing II, end clamping plate II and bar-shaped counter weight II.
When lifting drum turns to the solid arrow direction among Fig. 3 (counterclockwise); Pressing down wire rope is in by the state of reel rolling; Press down the wire rope tensioning; Tie up to and move and be stuck in orifice plate bearing I lacing hole place on the end clamping plate I that presses down on the wire rope, form a wire rope fixed end; Reel is rotated further, and then presses down movable pulley drive retaining wall pipe and is pushed down in the hole.And carry wire rope and be in the state of being emitted on this moment by reel, reel on carry wire rope and do not have pulling force, but bar-shaped counter weight II on carry wire rope a pulling force T arranged
2If do not put forward the frictional force between wire rope and the pulley on not considering, pulling force T
2Approximate the deadweight of bar-shaped counter weight II, on carry wire rope at pulling force T
2Effect makes wire rope inside that axial tension arranged down, and this masterpiece is used on the reel, has guaranteed that wire rope has a take-up force to reel, has prevented that the relaxed state of wire rope on reel from occurring.The rope length in two districts has difference d π because reel whenever turns around simultaneously; After reel rotates many circles; Just have one section long difference of rope, the long difference of this section rope makes end clamping plate II be pulled away from perforated panel bearing II one segment distance by the gravity of bar-shaped counter weight II, as shown in Figure 3.
When lifting drum turns to the dotted arrow direction among Fig. 3 (clockwise direction), on carry wire rope and be in by the state of reel rolling, on propose the wire rope tensioning, tie up to move on the end clamping plate II of carrying on the wire rope and (move promptly by pulling force T
2A previous segment distance that produces) and be stuck in orifice plate bearing II lacing hole place, form a wire rope fixed end; Reel is rotated further, and carries movable pulley on then and drives the retaining wall pipe and promote upwards.Be in the state of being emitted by reel and press down wire rope this moment, there is not pulling force in reel to pressing down wire rope, but bar-shaped counter weight I has a pulling force T to pressing down wire rope
1If do not consider to press down the frictional force between wire rope and the pulley, pulling force T
1Approximate the deadweight of bar-shaped counter weight I, press down wire rope at pulling force T
1Effect makes wire rope inside that axial tension arranged down, and this masterpiece is used on the reel, has guaranteed that wire rope has a take-up force to reel, has prevented that the relaxed state of wire rope on reel from occurring.
In sum because the effect of strainer, though press down wire rope and on carry wire rope and be in by the state of reel rolling, still be in the state of being emitted by reel, they are in the reel tensioning state.This has just been avoided wire rope relaxed state on reel, to occur, has produced the problem of irregular winding.
Through above transformation, put the overall process of pressing a work cycle of trailer system on the retaining wall pipe, can be decomposed into following 3 steps:
A. pile driver moves, and makes unsettled retaining wall mouth of pipe lower end place top, stake position; The operative employee starts hoist engine, handles the hoist engine cam controller, make press down wire rope through directive wheel, press down fixed pulley and press down movable pulley traction retaining wall pipe and move downwards; With the lower end mouth of pipe kiss the earth of retaining wall pipe, make the retaining wall mouth of pipe insert the soil certain depth at place, stake position more earlier.
B. hammer ram punching continues to press down the retaining wall pipe to projected depth.Enlarged footing part at the bottom of the compaction pile, fluid concrete.
C. the operative employee handles the hoist engine cam controller, makes the hoist engine antiport, on carry wire rope through directive wheel, on carry fixed pulley and on propose the upwards operation of movable pulley traction retaining wall pipe; The unsettled liftoff certain altitude of the mouth of pipe up to retaining wall pipe lower end.Carry the vibrator that Guan Shike opens retaining wall pipe upper end simultaneously, concrete is carried out vibration compacting.
In addition, mention a certain position on the retaining wall Guan Ruo, as pressing down, the operative employee can handle cam controller at any time again, changes hoist engine and turns to the operation that can reach change up-down direction immediately.Vice versa.
Relatively putting the operation procedure of pressing trailer system to improve front and back on the retaining wall pipe can see; Improve back retaining wall Guan Shangti, press down the running under power operation and need only change the lifting drum rotation direction by the operation of cam controller; Can change the traffic direction of retaining wall pipe; Settle at one go, the unloaded process of rotating the band suspension hook running block that descends of traditional hoist engine decoupling device, hook program and reel has been exempted in the centre.Than traditional Drop hammer pile driver, operating procedure is simplified to three by nine, obviously improves the pile driver efficiency of construction, alleviates operative employee's labour intensity.
