Abstract
The utility model relates to a pneumatic impact hammer which comprises an outer cylinder, wherein, blades are arranged on the outer wall of the outer cylinder. The blades are spiral blades or straightblades. The pneumatic impact hammer is provided with the blades on the outer wall of the outer cylinder, when in use, the pneumatic impact hammer is connected with a long spiral drill rod, the rotation directions of the long spiral drill rod and a protective cylinder are reverse during the construction process, a down hole head impacts a rock up and down under the action of high-pressure air, theresidual gas flies dust and stone ballast of the rock in a hole after the down hole head breaks the rock, and the broken stone or earth is transferred onto the spiral blades on the long spiral drillrod through the rotation guide of the blades, thereby discharging the broken stones and the earth out of a pile hole and improving the hole-forming efficiency and the hole-forming quality.
Description
Technical field
The utility model relates to a kind of pneumatic striking mechanism, is used for pile foundation construction.
Background technology
In the long-spiral drilling machine bore forming, the main principle of creeping into by the rig turnery.At present, obtained in the pile foundation foundation construction at home and abroad promoting widely and using, still, along with people's continuing to increase to stake hole depth and diameter requirement, especially at the improving constantly of the construction requirement of complex geological condition, traditional long-spiral drilling machine can not satisfy instructions for use.Particularly drill bit is difficult to fragmentation when running into hard rock, gravel layer, and pore-forming efficiency is low, bit wear is big.Pneumatic striking mechanism has the detritus advantage under this complicated geological, has solved the technical barrier of pore-forming difficulty when the long-spiral drilling machine pile runs into complicated geological.General pneumatic striking mechanism all comprises the outer shell of cylinder barrel shaped, and the fixedly connected joint that links to each other with long screw drill rod that is useful in the top of outer shell is equipped with jump bit in the outer shell, and the lower end of jump bit is fixedly connected with the down-the-hole head, and the down-the-hole head is positioned at the outside of outer shell.Inject pressure-air during use in outer shell, form vibration in vivo by various reversal valves, reciprocating reversing impacts the down-the-hole head, makes the down-the-hole head hit rock up and down, reaches the purpose of fractured rock.But after using existing pneumatic striking mechanism fractured rock, rock that is broken or soil are accumulated in the hole, discharge difficulty, have influenced pore-forming efficiency and hole quality.
The utility model content
The technical problems to be solved in the utility model provides a kind of easier in a fragmented rock or a soil discharge stake hole, pore-forming efficiency height, the pneumatic striking mechanism that hole quality is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of pneumatic striking mechanism comprises outer shell, and the outer wall of described outer shell is provided with blade.
Pneumatic striking mechanism of the present utility model, wherein said blade are helical blade.
Pneumatic striking mechanism of the present utility model, wherein said blade are prismatic blade.
Pneumatic striking mechanism of the present utility model, wherein said helical blade is welded on the outer wall of outer shell.
Pneumatic striking mechanism of the present utility model, wherein said prismatic blade evenly is provided with, and is provided with 4-8.
Pneumatic striking mechanism of the present utility model, wherein said prismatic blade is welded on the outer wall of outer shell.
The utility model pneumatic striking mechanism is provided with blade on the outer wall of outer shell, during use pneumatic striking mechanism is connected with long screw drill rod, in the work progress, the direction of rotation of long screw drill rod and casing is opposite, the down-the-hole head hits rock up and down under the effect of pressure-air, after the down-the-hole head smashes rock, remaining gas is kicked up the rock dust rock ballast in the hole, revolution guiding by blade, on rubble or the native helical blade that is passed on the long screw drill rod, thereby fragmented rock or soil are discharged the stake hole, improved pore-forming efficiency and hole quality.

The specific embodiment
As shown in Figure 1, the utility model pneumatic striking mechanism comprises the outer shell 3 of cylinder barrel shaped, and the top of outer shell 3 is fixedly connected with six square joints 1, and jump bit 2 is housed in the outer shell 3, and the lower end of jump bit 2 is fixedly connected with down-the-hole head 4, and down-the-hole head 4 is positioned at the outside of outer shell 3.The outer wall of outer shell 3 is provided with helical blade 11, and helical blade 11 is welded on the outer wall of outer shell 3.
As shown in Figure 2, in second kind of embodiment of the utility model pneumatic striking mechanism, evenly be provided with 4 prismatic blades 12 on the outer wall of outer shell 3, prismatic blade 12 parallels with the center line of outer shell 3, become 90 ° between the adjacent straight blade 12, form groove between the adjacent straight blade 12.Prismatic blade 12 is welded on the outer wall of outer shell 3.The quantity of prismatic blade 12 can be 4-8.
As shown in Figure 3 and Figure 4, when using the utility model pneumatic striking mechanism, pneumatic striking mechanism 6 is connected the lower end of long screw drill rod 5 by six square joints 1, source of the gas joins by the top of pipeline and long screw drill rod 5, helical blade on the long screw drill rod 5 combines at six square joints, 1 place with blade on the pneumatic striking mechanism 6, is convenient to the soil and the rubble of fragmentation are discharged on the ground.In the work progress, the direction of rotation of long screw drill rod 5 and casing 7 is opposite, and down-the-hole head 4 hits rock up and down under the effect of pressure-air.When blade is helical blade 11, after down-the-hole head 4 smashes rock, remaining gas is kicked up the rock dust rock ballast in the hole on the helical blade 11, revolution along with helical blade 11, rubbles etc. move up, be passed on the helical blade on the long screw drill rod 5, thereby rubble etc. is drained on the ground.When blade is prismatic blade 12, after down-the-hole head 4 smashes rock, remaining gas is kicked up the rock dust rock ballast in the hole, rubble dust etc. moves up along the groove between the adjacent straight blade 12, under the guide effect of groove, be passed on the helical blade on the long screw drill rod 5, thereby rubble etc. is drained on the ground.
Combine with existing long-spiral drilling machine when the utility model pneumatic striking mechanism uses, creep into and fetch earth and impact the lithosphere acting in conjunction and finish construction.Soil in the work progress and rubble by blade row to ground.The utility model pneumatic striking mechanism is constructed under complicated geologicals such as hard rock, ovum gravel, and to have broken rock speed fast, and single strike work is big, avoids borehole collapse, do not have to repeat brokenly, and the rubble speed that fetches earth continuously is fast, drilling efficiency height, advantage such as environmental pollution is little.
Table 1 is depicted as the comparison of the hole forming method that socketed pile is commonly used in the civil engineering, and by contrasting the advantage that can find the utility model pneumatic striking mechanism, hole quality is good, pore-forming efficiency is high, environment pollution is little etc.
The hole forming method that table 1 civil engineering socketed pile is commonly used
