Detailed Description of the Preferred Embodiments
Referring to the drawings, and in initially to Figs. 1 to 3 thereof, there is illustrated a post driver assembly according to the invention indicated generally by the reference numeral 1. The post driver assembly 1 comprises a mast 2 with an associated hammer 3 which is mounted on the mast 2 and is operable for driving a post into the ground. The mast 2 is pivotally mounted on a telescopic support boom 4 to facilitate positioning of the mast for driving a post into the ground. This support boom 4 is mounted on a swivel mount indicated generally by the reference numeral 5 for pivoting the support boom 4 about a substantially vertical axis. That is, when the support boom 4 is horizontal it pivots about a vertical axis.
The swivel mount 5 is operable to swing the support boom 4 through at least 90°, more preferably through 180° and most preferably through about 220° or more if required. In this case the swivel mount 5 comprises a rack and pinion mechanism having a rack 7 and a complementary pinion 8. A ram 9 is operable to move the rack 7 linearly to rotate the pinion 8.
The swivel mount 5 includes a mounting plate 10 on an underside of which the rack 7 and pinion 8 are mounted. A drive shaft 12 on which the pinion 8 is mounted extends through the mounting plate 10 to engage the support boom 4. An upstanding tubular bearing housing 14 on the mounting plate 10 rotatably supports the drive shaft 12. Mounting' brackets 15 at an upper end of the drive shaft 12 secure the drive shaft 12 to a side 16 of the support boom 4.
The support boom 4 comprises an inner fixed tubular sleeve 18 and a complementary movable inner arm 19 which is telescopically slidable within the
-6sleeve 18. The mast 2 is pivotally mounted at an outer end of the arm 19 by means of a pivot mount indicated generally by the reference numeral 20 and an associated counter-weight 22 is mounted at the inner end of the sleeve 18 at an opposite side of the swivel mount 5 to the mast 2.
The pivot mount 20 is operable to pivot the mast 2 in two mutually perpendicular directions. The pivot mount 20 comprises a first pivot formed by a pivot shaft 23 having a first pivot axis substantially parallel to a longitudinal axis of the support boom 4 and a second pivot formed by a pivot pin 24 having a second pivot axis which is substantially perpendicular to the first pivot axis of the pivot shaft 23.
The pivot shaft 23 is mounted in a complementary tubular pivot housing 25 carried between support brackets 26, 27 at an outer end of the arm 19. A pair of pivot pin mounting brackets 30 project outwardly of the outer bracket 27 and cooperate with an associated pair of pivot pin mounting brackets 31 on a rear of the mast 2 and the pivot pin 24 to form the second pivot. As it will be appreciated from the drawings, the pivot shaft 23 allows the mast 2 to pivot to each side of the support boom 4 and the pivot pin 24 allows the mast 2 to pivot in alignment with the support boom 4.
A first mast tilt ram (not shown) extends between a mounting arm 35 which projects laterally to one side of the arm 19 at an outer end thereof and a plate 36 at an outer end of the pivot shaft 23 to pivot the pivot shaft 23 in the bearing housing 25. A second mast tilt ram 40 is mounted between associated support arms 41 projecting rearwardly from the plate 36 and an associated mounting bracket 42 on the mast 2 to swivel the mast 2 on the pivot pin 24.
An hydraulic control station 45 is mounted at one side of the plate 36 with the usual levers for controlling the supply of hydraulic fluid to the various rams 9, 40, etc. for controlling operation of the post driver assembly 1.
In use, the support boom 4 can be swivelled horizontally through approximately 220° by operation of the ram 9 controlling the rack and pinion mechanism of the swivel mount 5. Also the mast 2 can be swivelled on the pivot shaft 23 and pivot pin 24 to tilt the mast 2 to each side and forward and back.
-7Various different post driver mast assemblies could be used and these have not been described in detail here. The mast assembly could, for example, be similar to that already described in our previous Patent Application Publication No. EP2159332. The mast 2 shown also incorporates a rock spike 50 and its operation and construction is similar to that of the rock spike described in EP 2159332.
Referring now to Figs. 4 to 11, there is illustrated a post driver vehicle indicated generally by the reference numeral 60 according to another embodiment of the invention which incorporates the post driver assembly 1 described previously. Parts similar to those described previously are assigned the same reference numerals. In this case the mounting plate 10 is bolted to a chassis 61 of the vehicle 60. A vehicle cab and driving position for the vehicle 60 which is mounted on the chassis 61 in front of the post driver assembly 1 is not shown. The chassis 61 is mounted on a pair of tracks 62 which are hydraulically driven and controlled from the cab of the vehicle and also can be controlled from the control station 45. As can be seen in the drawings, the mast 2 can be swivelled to either side of the vehicle 60 or to a rear of the vehicle 60.
In order to prevent possible injury to an operator when operating the post driver when the mast 2 is located at the rear of the vehicle 60, the controls prevent operation of the vehicle drive when the mast 2 is mounted to the rear of the vehicle 60. This can be achieved, for example, by providing a cam collar on the tubular bearing housing 14 and an associated cut-out switch on the drive shaft 12 having a spring-loaded reciprocating actuating rod which engages the circumferential cam surface of the cam collar to move the actuating rod to switch on and off the hydraulic fluid supply to the vehicle drive.
Preferably the post driver assembly 1 is demountably secured to the chassis 61 and can be removed to allow a trailer, dumper or other device to be mounted on the vehicle as required.
Figs. 12 to 16 show another post driver vehicle indicated generally by the reference numeral 80. Parts similar to those described previously are assigned the same reference numerals. In this case the mounting plate 10 is slidably mounted on the chassis 61 of the vehicle 80 for movement in a longitudinal direction on the vehicle 80, forward and back by means of rams 81 mounted between the mounting plate 10 and
-8the chassis 61. Opposite sides 82, 83 of the mounting plate 10 engage associated slide rails 84, 85 on the chassis 61 to allow sliding movement fore and aft on the chassis 61. Thus, if required, the mounting plate 10 can be moved forward on the chassis 61 for better weight distribution and traction when driving the vehicle 80.
The invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail within the scope of the appended claims.
