Description

Compactor by hydraulic pneumatic actuation {The compactor to oil pressure a shock}

The present invention relates to a compactor for solidifying the retaining wall using heavy equipment such as an excavator to compact the retaining wall and the ground after construction, or the retaining wall of the non-dedusted ground at the roadside after completion of the construction. Specifically, the compactor compaction plate striking device of the compactor mounted on the end of a heavy equipment arm, such as a fork crane (excavator) to hit the compactor compaction plate by reciprocating up and down operation of the piston to be lifted up and down by hydraulic pressure. The present invention relates to a compactor by hydraulic pneumatic operation that can maximize the efficiency of compaction work.

As is well known, pipes are buried in the ground after excavating the ground for gas construction, water supply and sewage plumbing, etc. At this time, dig the retaining wall firmly and then perform the plumbing work. Compaction work is performed for finishing work. To do such compaction work, the compaction compactor is mounted on the end of heavy equipment arm such as a fork-lane (excavator). After chopping evenly, you will:

At this time, the used compactor is the same as the compactor as shown in the photo of Figure 4, such a conventional compactor (1) is a housing 4 and the upper end of the housing 4 formed in both sides, such as a fork crane or an excavator A fastening portion 3 is formed at the end of the arm 8 for easy installation, and a compacting portion 6 and a striking portion 2 for reciprocally hitting the compacting plate 6 are provided at the lower end of the housing 4. And a motor driving part 5 for driving the hitting part 2 is formed, and an impact plate 7 formed on an upper surface of the compaction plate 6 and an unshown hitting hole of the hitting part 2 is formed. By the driving of the motor driving unit 5, the hitting hole continuously hits the impact plate 7 repeatedly, and the impact force is transmitted to the ground by the compaction plate 6, so that the ground or retaining wall is unevenly formed. It is common to keep it compact.

However, the conventional compactor has a problem in that the main power has a structure that transmits the impact force to the compaction plate by the driving force of the motor, and the impact force cannot be greatly increased because it must depend on the power of the standardized motor. There was a limit that more efficiency could not be expected in performing ground compaction.

Such problem is that if the ground collapse such as the construction of the foundation for excavation foundation work of gas construction or water supply and sewage construction directly threatens the safety of workers, the compactor with considerable driving force of the motor should be adopted. In this case, the size of the compactor becomes considerably larger in proportion to it, and even if the construction is adopted by adopting a compacter having a corresponding size with a corresponding power, the fork-lane, etc., due to its own compactor weight and impact force, etc. There is a problem that greatly threatens the balance of heavy equipment, and fatal problems such as unable to guarantee the safety of workers.

In addition, in compacting a relatively narrow retaining wall, the compactor has a large size, which makes it difficult to compact a narrow retaining wall or a narrow slope of the road.If the motor is used for a long time, the equipment according to the compactor Of course, the inconvenience of having to replace the motor periodically and the maintenance cost has been raised, and accordingly, there was a problem that the maintenance cost of the compactor has to be significantly input.

Therefore, the present invention has been made to solve the above problems, the object of the present invention is to provide a compactor to ensure the stability of the work, as well as to achieve a functional improvement of the compactor of a relatively small size It is an ultimate object of the present invention to provide a compactor for maximizing the efficiency even when compacting by compactor for compaction.

Hereinafter, with reference to the accompanying drawings, an embodiment of the configuration and operation of the present invention will be described in detail as follows.

Figure 1 is an exploded perspective view of the present invention, Figure 2 is a cross-sectional view of a hydraulic pneumatic adopted to the present invention, showing a state before being struck, Figure 3 shows a state in which the piston struck by Figure 2 Figure is shown.

As shown in FIG. 1, the present invention is largely divided into the compaction part 100 and the perforation part 200. First, the configuration of the compaction part 100 will be described.

As shown in Figure 1 or 2, 3, the compaction portion 100 of the present invention is formed of a material such as cast iron for compacting the ground to the bottom and the compaction plate having a predetermined width and length that both ends are bent upwardly A molding plate 120 is formed, and the housing plate 110 made of a cast iron having a predetermined thickness is disposed on the upper surface of the compaction plate 120 so as to face each other.

At this time, the interval between the housing plate 110 is to maintain the interval that can be inserted into the cylinder 240 body of the perforation 200 to be described later.

Meanwhile, the front side of the housing plate 110 allows the bolt hole 112 to be perforated in a state in which a plurality of tanks are arranged so as to be fixed to the cylinder 240 of the perforation part 200 to be described later, and on the housing plate 110. In the side, each of the fastening holes 111 to be fixed to the end of the arm portion of heavy equipment such as fork cranes or excavators to each end.

At this time, by arranging and welding a plurality of reinforcing members 115 between the lower end of the housing plate 110 and the upper surface of the compaction plate 120, the housing plate 110 and the compaction plate 120 are firmly coupled and fixed. The housing plate 110 in the same state to be fixed to the shape that is disposed opposite to the upper surface of the compaction plate 120, and in this state to maintain and reinforce the inner gap between the housing plate 110 and the housing plate 110 Reinforcement fixing support plate 114 for protection from impact is fixed to the transverse welding to maintain the distance between the housing plate 110, as well as, the housing plate 110 from the impact force transmitted during the perforation of the perforations 200 to be described later ), As well as to ensure that the gap between the housing plate 110 in the opposite state is always maintained.

Meanwhile, by welding and fixing the fixing plate 121 to the gap between the housing plates 110 and the upper surface of the compaction plate 120, the impact plate 210 is fixed to the end of the hitting rod 220 of the perforation part 200 to be described later. To transmit the impact force to the compaction plate (120).

Meanwhile, the punching part 200 repeatedly performs the vertical lifting operation of the piston 270 by the hydraulic pressure that is repeatedly supplied, thereby strongly hitting the upper end of the hitting rod 230 in a state spaced a predetermined distance from the lower end of the piston 270. While the impact force is transmitted to the fixed plate 121 of the impact plate 210 and the compaction unit 100 integrated with the lower end of the rod 230, the compaction plate in the welded fixed state with the fixed plate 121 ( 120) strikes the ground to perform the compaction work.

At this time, the internal configuration of the cylinder 240 of the perforation 200 has a configuration for repeatedly punching the upper end of the hitting rod 230 by hydraulic pressure, the configuration of the perforation 200 is adopted in the present invention An example will be described.

First, as shown in FIGS. 2 and 3, the perforation part 200 is provided with an impact plate 210 fixed to the lower end of the striking rod 230 to strike the fixed plate 121 and the compaction plate 120. A plurality of holes 212 and bolts 211 are fixed to the impact plate 210 to be screwed with the lower end of the cylinder 240 to be hollow and a plurality of holes 212 and the impact plate 210, and the impact plate ( 210 to be screwed with the anti-vibration rubber 220 at the bottom is provided to absorb the impact force to a certain extent when the impact rod 230 is hit by the piston 270 of the cylinder 240, the anti-vibration rubber ( A fixed plate 121, which is welded and fixed to the upper surface of the compaction plate 120, is positioned at a lower end thereof, and penetrates the shock plate 210, the anti-vibration rubber 220, and the fixed plate 121 with bolts 213, etc. To be fixed and to the hydraulic flow up and down from the hitting rod 230 Piston 270 which is driven up and down the sea, valve 257 for controlling the direction of the hydraulic pressure supplied to the piston 270, the valve 257 and the valve high-pressure chamber 253, the valve hydraulic chamber 252 ), A valve housing 250 in which the valve switching chamber 255 is formed is formed, and the cylinder low pressure chamber 243, the cylinder switching chamber 244, the cylinder chamber 245, the cylinder gas chamber 241, and the cylinder upper chamber 242 are formed. A back is formed inside the cylinder 240 which is arranged in an annular arrangement sequentially inside the cylinder 240, and the valve high pressure chamber 253 and the cylinder base 245 are connected to inlet gas into the cylinder 240 side. A high pressure passage 259 and a gas chamber 258 are formed to facilitate operation.

Referring to the operation state of the perforation part 200, the pressure oil flowing into the high pressure inlet 260 side formed in the valve housing 250 side in the initial stage of the piston 270 passes through the valve high pressure chamber 253, at this time Part of the pressure oil flows into the valve pressure receiving chamber 252 and acts on the piston lower pressure receiving surface 273 to act as a force for raising the piston 270. At this time, the low pressure outlet 261 of the valve 257, the valve low pressure The chamber 253 ', the cylinder low pressure chamber 243, the cylinder switching chamber 244, and the valve switching chamber 255 are simultaneously formed at low pressure so that an upward force acting on the valve switching hydraulic pressure surface 256 is applied to the valve hydraulic pressure surface 256. ) Is smaller than the force applied to the valve 257 is a shape that is located in the bottom dead center state, the cylinder upper chamber 242 is the valve inner chamber 251, the valve flow path hole 254, the valve low pressure chamber 253 'and It is connected to the valve low extruded port 261 side to act as a low pressure on the piston upper hydraulic pressure surface (272). That is, the piston 270 compresses the gas in the cylinder gas chamber 241 by the upward force acting on the piston lower hydraulic pressure surface 273, thereby increasing the operation.

When the piston 270 is raised as described above, the piston lower pressure surface 273 is raised to the position of the cylinder switching chamber 244, accordingly, the cylinder switching chamber 244 is connected to the cylinder chamber 245, the valve switching chamber 255 is switched to a high pressure, the high pressure acts on the valve switching pressure receiving surface 256 having a larger area than the valve pressure receiving surface, and the valve 257 is operated to increase.

When the valve 257 is operated upward as described above, the valve high pressure chamber 253, the valve channel hole 254, the valve inner chamber 251 are raised to the position of the valve flow path hole 254 and the valve high pressure chamber 253. And when the cylinder upper chamber 242 is switched to the high pressure and the high pressure acts on the upper piston pressure receiving surface 272, the area of the piston upper pressure receiving surface 272 becomes larger than the piston lower pressure receiving surface 273, so that the difference in area The piston 270 is subjected to the downward action by the force acting downward by the compressed gas of the cylinder gas chamber 241 is added to the piston 270 is lowered at a considerable speed, such as the piston 270 When the piston stage 271 is lowered to the position of the cylinder switching chamber 244 before the lowering operation is completed, the cylinder switching chamber 244 is connected to the cylinder low pressure chamber 243 again so that the valve switching chamber 255 is switched to the low pressure state. And the valve 257 is lowered in conjunction with this It becomes. As described above, when the piston 270 maintains the descending state at the same time as the lowering operation of the valve 257, the piston 270 is hitting the upper end portion of the striking rod 230 strongly and reaches the lower end of the striking rod 230. The impact force is transmitted to the load plate 120 through the impact plate 210 and the fixing plate 121 is connected to the ground, it is possible to compact the ground or retaining wall.

In this way, when the blow is completed, the piston 270 and the valve 257 are in an initial state, that is, both are in a lowered state, so that an upward flow path of the piston 270 is formed, and the high pressure inlet is repeatedly performed in a standby state for the next cycle. The hydraulic pressure is provided to the side 260 to repeatedly perform the above operation in a short time so that the lower end of the piston 270 repeatedly hits the upper end of the hitting rod 230.

At this time, the structure of the cylinder and the inside of the valve housing by the operation state of the piston inside the cylinder of the perforated part and the operation of the valve in the valve housing is generally adopted and adopts a structure such as a hydraulic breaker for crushing rock or rock. The example used for the present invention has been described with reference to one embodiment.

That is, the biggest feature of the present invention is to avoid the complicated work process such as the structure of the compactor using the motor used in the prior art and the frequent repairs due to the decrease in the efficiency (compacting) in use and the failure of the motor that occurs frequently during use. The hydraulic force is used to transfer the motive force transmitted from the piston by the repeated up and down operation of the piston by hydraulic pressure to the impact rod and the impact plate, dustproof rubber, and compaction plate formed at the lower end of the impact rod, and thus to ground or retaining wall. Since it is to be very useful for compacting, the reciprocating up and down operation of the piston in conjunction with it by the repetitive supply of hydraulic pressure, regardless of the structure of the valve housing and the cylinder as described above spaced apart at the lower end of the piston The hitting rod that is in the state of being hit, the criminal does not escape the spirit of the present invention Various changes and modifications by one of ordinary skill in the art to which it belongs within the instant invention and can be designed.

Therefore, according to the present invention, the compactor for compacting the retained wall ground or non-dedusted ground of the roadside during gas pipe construction is combined with the end of the impact rod hit by the piston by reciprocating up and down operation of the piston by hydraulic pressure. As it delivers to the impact plate and at the same time, it compacts the ground by hitting the compaction plate of the compactor, it is possible to express the same impact force with a relatively compact compactor in comparison with the size and specifications of the compactor using a conventional motor. It is very easy to compact a relatively narrow retaining wall or sloped roadside.

In addition, since the compactor is operated by hydraulic pressure, it is possible to significantly reduce the incidence of failure during use, and maximize the reduction of maintenance cost by periodically replacing the motor or removing secondary work requirements such as motor repair. In addition, even when a large impact force is required, a large impact force can be obtained even in a state where the size of the compactor is minimized. Therefore, work safety can be performed without losing the balance between safety of heavy workers and heavy equipment. It can be expected to be effective in securing and preventing safety accidents.
