APPARATUS FOR DRIVING IN FILES, PLANKS AND THE LIKE Filed May 28, 1968 INVENTORS PH/L/P/ 0655A 144/0 H62. M07 HfCK/Vffi BY United States Patent US. Cl. 173131 2 Claims ABSTRACT OF THE DISCLOSURE Pile or plank driving apparatus comprising a manually guided rapidly beating tamping device which employes a ram block in lieu of a tamping plate and includes guide means associated With the ram block and a guide head movably connected with the guide means and a ram bolt associated with a beating die with which it is connected in force transmitting fashion and which is displaceably mounted relative to the guide head.
BACKGROUND OF THE INVENTION The invention relates to driving or ramming equipment such as pile driving apparatus for ramming or driving in piles, posts, planks and similar elements by means of a known rapidly beating manually guided, and motor driven driving or ramming device. Such ramming devices may be of the general construction illustrated in US. application Ser. No. 654,267, of Philipp Uebel, one of the applicants.
Working tools for driving in piles and planks are known in dilferent forms of construction. The heavy and medium-heavy ram heads constitute short thrust machines of considerable mass where the ramming is accomplished by pure beating action, Owing to their weight, such machines can only be moved to operating locations by means of a carrying vehicle, for example, a dredge or excavator.
Furthermore, also light ram heads and hand hammers are known. The light ram heads are similar in construction and manner of operation to heavy and medium-heavy ram heads, with the difference that weight and output are relatively small. On the other hand, the hand hammers or engineers hammers constitute rapidly beating devices of relatively small mass where the ramming is obtained by a vibration effect.
During working operations ram blocks or heads rise after each blow from the object or element to be driven so that for guiding these devices additional expensive guiding frames or structures are required.
Vibration blocks or rammers are also known. The application thereof, however, is not successful in all-building sites and with all types of ground. Moreover, these devices are very heavy so that they have to be moved to the working site by a carrier'vehicle, for example, a dredge.
It is an object of the invention to provide a device which makes possible the use of rapidly beating tamping or stamping equipment which produces essentially greater ramming effects as compared, for example, to hammers, because the mass of the ram head or block is naturally greater than it is with a hammer.
SUMMARY OF THE INVENTION In accordance with the invention, it is an object to solve this problem by providing instead of a tamping plate on the tamping device a ram head having a guiding means, and that with this guiding means another guiding means is movably connected in which a ramming bolt connected in force-transmitting fashion with a beating die is movably mounted.
Further features of the invention provide for guide bars that are movably disposed in the guide means arranged on the ram head and which are connected rigidly or exchangeably with the other guiding means, and the ram bolt is movably disposed in this guide means by way of spring elements and a straight guide means.
In accordance with a further embodiment of the invention, the guide means provided on the ram head is in the form of a cylindrical tube in which the other guide means is arranged by way of straight guide means to safeguard against rotation.
The advantage of the arrangement in accordance with the invention resides in that the working device producing the beating energy may be a rapidly beating manually guided tamper.
As compared to the known and heavy rammers, which can be brought into operating locations only by means of a transporting vehicle, for example a dredge, tampers of this type are light and, therefore, they can also be easily manipulated by an operator. On the other hand, as com pared to rammers, the number of beats per minute with these tampers is high, as it is with hammers. The advantage over a hammer resides above all in that the mass of the rammer head is naturally greater than with a hammer, 7
so that also the beating force of the individual beat is a plurality of times greater.
By using the apparatus in accordance with the invention, the known manner of operation of a tamping device is converted to the manner of operation of a hammer. This arrangement makes even possible the driving of big poles and planks or the like. The rapid succession of beats of the tamping device used proves to be advantageous in that with respect to rammers having a low number of beats per minute with which the penetration, for example, of a plank depends only on the force of the individual blow, without considering the prevailing ground conditions, a vibration effect is obtained by the rapid succession of beats which together with the great force of the mass results in a movement of the plank that is comparable to sliding 0r flowing.
The beating die in force-transmitting connection with the beating bolt is advantageously so adapted to the object to be driven in, that it serves simultaneously as guide for the ramming device, and therefore also of the tamping device. As a result, the expensive guiding slides or frames necessary in known rammers for guiding the operating device are eliminated. This structural possibility results from the fact already mentioned, that the device in accordance with the invention causes the manner of operation of the tamping device to be converted to that of a hammer because the guiding means which carries the ram bolt and ram die rests calmly upon the object to be driven in, while the tamping device with the ram head is journalled for axial movement in the other guiding elements.
BRIEF DESCRIPTION OF THE DRAWINGS Further features and advantages of the invention will become apparent from the following description with reference to the embodiments illustrated in in the accompanying drawings in which:
FIG. 1 illustrates an embodiment of the invention partly in section, and
FIG. 2 illustrates a further embodiment of the invention in section.
DESCRIPTION OF THE INVENTION A ram block or head 2 is rigidly mounted by suitable means on a rapidly beating tamping device in lieu of a tamping plate. The ram block 2 is firmly connected with guide members 3. In the embodiment in accordance with FIG. 1 guided rods 4 are movably mounted in the guide 3 members 3. The guided rods 4 are firmly or exchangeably connected with the guided head 5. The ram bolt 6 i8 movably mounted on the guided head with a straight guide 7 therebetween and intermediate spring members 8 and 9. The ram bolt 6 is connected in force transmitting fashion with the beating die 10.
In the embodiment in accordance with FIG. 2 the guide member 3 which is firmly connected with the ram block or head 2 is in the form of a cylindrical tube. A guided head 5 which is also of cylindrical shape is movably mounted in the guide member 3 and is prevented from turning by a straight guide means 11.
The blow produced by a rapidly beating tamper 1 is transmitted by the ram block 2 that is firmly connected with the tamper 1 onto the upper end of the ram bolt 6. The ram bolt 6 is connected in force transmitting fashion to the beating die so that the beating force exerted by the ram block 2 onto the ram bolt is applied directly to the object to be driven in. The beating die is constructed in such a manner with respect to the shape of the object to be driven in that the tamper is guided upon the object to be driven in by way of the beating die 10 and cannot tilt. The spring members 8 and 9 are not required for force transmission. However, they serve as elastic support for the entire apparatus with the tamper and for intercepting any return shocks.
Having now described our invention with reference to the embodiment illustrated in the drawings, what we 4. desired to protect by Letters Patent ofthe United States is set forth in the appended claims.
We claim:
1. Apparatus for driving in piles, planks and the like by means of a manually guided rapidly beating tamping device comprising a tamping device provided with a ram block in lieu of a tamping plate, a guide means on said ram block, a guided head movably connected with said guide means for sliding movement relative thereto and a ram bolt connected in force transmitting fashion with and supporting a beating die, said ram bolt being displaceably mounted relative to said guided head, said guide means being in the form of cylindrical tube means supported on said ram block.
2. Apparatus in accordance with claim 1 comprising straight guide means arranged intermediate said guided head and said guide member.
