The present invention relates to an apparatus for driving drain pipes into the natural slopes, earth dams or enbankments, the drain pipes being driven into the ground without disturbing the stability of the slopes or the like.
SUMMARY OF THE INVENTION An object of the present invention is to provide a drain pipe driving apparatus best adapted to drive the drain piles into the slopes or embankments.
The present invention provides driving apparatus provided with a pendulum-like motor-driven hammer and adapted to drive drain pipes into the slopes or the like at any position thereof in a very efficient manner.
The above and other objects, features and advantages of the present invention will become more apparent from the following description of some preferred embodiments thereof taken in conjection with the accompanying drawing.
BRIEF DESCRIPTION OF THE DRAWING FIG. I is a perspective view of a driving apparatus;
FIG. 2 is a diagrammatic view illustrating the interior of a motor-driven hammer thereof;
FIG. 3 is a side view thereof;
FIGS. 4 and 5 are side views of the driving apparatus shown in FIG. 9 illustrating the steps of driving the drain pipe;
FIGS. 6 and 7 are perspective view illustrating an other driving appratus and the steps of driving the drain pipe.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 7 the driving apparatus generally indicated by 50 and 51 for driving the drain pipe of the type described hereinbefore into the ground will be described hereinafter. The driving apparatus 51 shown in FIGS. 1 to 5 is used for driving the drain pipes into the ground relatively close to the base of the slope whereas the driving apparatus 51 shown in FIGS. 6 and 7 is used for driving the drain pipes into the slope except the place where the driving apparatus 50 is applicable.
Referring to FIG. 1 the driving apparatus generally indicated by 50 comprises three supports 54a, 54b, and 540 each of which consists of a top brace member 52 and a pair of legs 53 joined to pedestals 56, respectively, through turnbuckles so that the height of each leg 53 may be adjustable. An anchor pile 57 is driven into the ground through a hole formed through the pedestal 56 so that the pedestal 56 may be securely held in position. A socket 58 is securely fixed to the top brace member 52 at the center thereof for receiving therein the end ofa guide rod 59 ofa desired length. The guide rods 59 are securely held in the sockets 58 by means of bolts 60. Therefore the supports 54a, 54b and 540 may be spaced apart by a predetermined distance from each other and held securely upon the ground.
The driving apparatus 50 further comprises a movable frame generally indicated by 61 and adapted to move along the guide rods 59. The movable frame 6] comprises a horizontal beam carried by carriages 67, a vertical rod 62 extending downwardly from the end of the horizontal beam remote from the right carriage 67 and having its lower end terminated into a guide plate 64 with a drain pipe guide hole 63, and a pair of quadrant guide members 65 having their ends joined to the horizontal and vertical beams, respectively. The pair of guide members 65 also serve as brace members between the horizontal and vertical beams 61 and 62, and guide a pendulum rod 69 of a motor-driven hammer 66 to be described in more detail hereinafter. The carriages 67 are similar in construction, and each comprises a pair of frames 67 having a roller 68 attached thereto. The rollers 68 ride on the guide rods 59 so that the movable frame 61 may be movable in parallel with the guide rods 59 as the drain pipe 30 is driven into the ground in a manner to be described in more detail hereinafter.
In order to drive the drain pipe 30 into the ground, the pendulum-like motor-driven hammer 66 suspended by the pendulum rod 69 which in turn is pivoted to the right carriage 67 with a pivot 70 and is guided by the guide members 65 so as to prevent the lateral movement.
Next referring to FIGS. 2 and 3 the motor-driven hammer 66 will be described. Within a housing 71 a pair of motors 73 are mounted upon a mount 72, and a winch comprising a drum 77 with a wire rope 78 wound therearound and a clutch 76 is loosely supported by a shaft which in turn in supported by a pair of brackets 74 securely fixed to the mount 72. The rotation of each motor 73 is transmitted to the shaft 75 through a belt drive consisting of a drive pulley 80 fixed to a driving shaft of the motor 73, a driven pulley 81 fixed to the shaft 75 and an endless belt 82 wrapped around the driving and driven pulleys 80 and 81.
The right clutch section 76 which is loaded with a spring 91 is provided with an annular groove 83 into which is fitted a pin 85 extending from one end of an actuating or operating lover 84 which is pivoted to the base 72 with a pin 86 and whose the other end is pivoted to a plunger with pin 88 of a plunger and solenoid assembly 87. Therefore as the plunger and solenoid assembly 87 is energized or de-energized the right clutch section 76 is slidably moved along the shaft 75 to engage with or disengage from the mating left clutch section 89.
One end of the wire rope 78 is securely fixed to the drum 77 whereas the other end is fixed to an car 90 fixed to the horizontal beam 61 (See FIG. I).
A brace rod 92 which is joined to the brackets 74 serves to ensure the wire rope 78 to be wound around the drum 77.
When the motors 73 which are supplied with power through a cable 93 are driven, their rotation is transmitted to the clutch section through the driving pulley 80, the endless belt 82, the driven pulley 81 and the shaft 75. When the clutch section 76 is engaged with the mating clutch section 89 as the plunger and solenoid assembly 87 is energized. the drum 72 which is loosely fitted over the shaft 75 is rotated to wind the wire rope 78 theraround. As a consequence the motor-driven hammer 66 is swung about the pin 70 upwardly. When the solenoid 87 is de-energized when the motor-driven hammer 66 is lifted to a predetermined height, the right clutch section 86 is disengaged from the left clutch section 89 so that the free rotation of the drum 77 is permitted. As a result the motor-driven hammer 66 swings back to drive the drain pipe 30 as shown in FIG. 12. The pendulum-like driving operation is cycled so that the drain pipe 30 is gradually driven into the ground as shown in FIG. 5.
The driving apparatus 51 which will be described hereinafter with reference to FIGS. 6 and 7 is substantially similar in construction to the driving apparatus 50 except its supports or supporting frames are different. As shown in FIG. 6 the left end of the guide rod 94 is joined to a pipe 96 with a bolt 97 of a foot member 95 securely held in position on the slope by means of anchor piles 109. The right end of the guide rod 94 is sup ported by a supporting frame generally indicated by 103. The supporting frame 103 comprises an inverted U-shaped upper leg 99 whose lower end portions are telescopically fitted into lower legs 101 whose lower ends are securely fixed to pedestals 100 which in turn are securely held in position by means of the anchor piles 109. The height of the supporting frame 103 is therefore adjustable and the inverted U-shaped leg 99 can be securely held in position relative to the lower legs by means of bolts 102.
The supporting frame 103 is further supported by a pair of telescopic brace means, each comprising an inner brace rod 105 whose one end is pivoted to the inverted U-shaped leg 99 with a pin or rivet 104 and whose the other end portion is telescopically fitted into and securely held in position with respect to an outer brace pipe 107 with a bolt 108. The outer brace pipe 107 is securely fixed to a foot which in turn is securely held in position on the slope by means of the anchor piles 109. The length of the telescopic brace means is therefore adjustable. Furthermore stay wire ropes or chains 110 are extended from anchor bolts(not shown) driven into the ground on the slope and are fixed to hooks 111 fixed to the pedestals 100 so that the pedestals 100 so that the pedestals 100 may be further securely held in position.
The movable frame 61 and the pendulum-like motordriven hammer 66 are mounted in a manner substantially similar to that of the driving apparatus 50, but it should be noted that the motor-driven hammer 66 is not suspended from the carriage 67 but from a suspending frame 112 fixed to the horizontal beam 61, that instead of the guide plate 64 a U-shaped guide member 64 made of a rod is used and that the 53 guide members 65 are straight. The above arrangements different from those of the driving apparatus 50 are merely a matter of design, and both the driving apparatus 50 and 51 are based upon the same principle.
The driving apparatus 50 or 51 is used to drive the drain pipes 30 into the slope depending upon the positions on the slope where the drain pipes 30 are driven. ln operation the movable frame 61 is moved to the initial or right position as shown in FIGS. 4 and 6, and the drain pipe 30 to be driven is inserted through the guide plate or member 64 so that the drill section of the drain pipe 30 may be placed in correct position. Thereafter an impact receiving cap 114 is screwed to the rear end of the drain pipe section 31, so that the starting position of the guide member or plate 64 and hence the movable frame 61 is automatically determined. Thereafter the motor-driven hammer 66 is operated in the manner described hereinbefore to give the driving impact to the impact receiving cap 114, thereby driving the drain pipe 30 into the ground. As the drain pipe 30 into the ground the movable frame 61 and hence the motordriven pendulum hammer 66 are automatically advanced because of the engagement of the impact receiving cap 114 with the guide plate or member 64 as shown in FIGS. 5 and 7.
So far the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawing, but it is to be understood that variations and modifications may be effected without departing the true spirit of the present invention.
