Description
Technical field
The present invention relates to a kind of excavation machinery, relate in particular to a kind of excavation machinery with rotary impact function.Be mainly used in the construction of the priming concrete pile hole of subsurface rock geological stratification.
Background technology
In the prior art, castinplace pile is widely used in the construction of highrise building, highway, railway, bridges and culverts and subway engineering.The construction of the castinplace pile of underground rock geology layer adopts the efficiency of construction of common construction machinery too low, so the rotary impact hammer is widely adopted.The construction of priming concrete pile hole adopts the steel pipe casing to impact construction technology, mainly is to utilize jump bit that underground lithosphere is carried out the impact of upper frequency, makes catalase; Utilize the steel pipe casing can prevent landslide simultaneously, when excavating, water poured into in the steel pipe casing, rubble earth etc. is diluted to mud after, take out by slush pump, after excavation is finished, extract the steel pipe casing, pour into again.Therefore, the rotary impact hammer is the main tool of the priming concrete pile hole construction of subsurface rock geological stratification.Yet when construction operation, the jump bit in the steel pipe can be to the reaction force of its generation to the impact of rock.Because whole jump bit all is immersed in the slime water, the hammer that liquidates has a buoyancy that makes progress, and adds the reaction force when impacting, although the bulky of jump bit, it is also big to conduct oneself with dignity.But because the existence of hard and these two kinds of power of subsurface rock, foot can make upwards bounce-back of jump bit, has slackened the impact force of jump bit, thereby has influenced the operating efficiency of jump bit.
Summary of the invention
The objective of the invention is: overcome the influence of the reaction force of jump bit, a kind of rotary impact hammer that has steel pipe tube wall brake stretching device is provided.
The present invention is achieved in that a kind of rotary impact hammer, is made up of suspender, rotary power unit, linkage, mud suction pipe, percussion mechanism, slewing equipment, and described suspender is fixed on the rotary power unit; Described percussion mechanism is made of hydraulic impactor and impact head, a described front end of being located at hydraulic impactor that impacts; Described mud suction pipe is fixed in the outside of hydraulic impactor, and is connected by the slush pump of pipeline with the outside; Described hydraulic impactor also constitutes the loop by pipeline with the fueller of outside and is connected; It is characterized in that: described slewing equipment is made up of revolution connecting axle, bearing, axle sleeve, is provided with bearing between described revolution connecting axle upper end and the axle sleeve; Described rotary power unit is fixedlyed connected with the upper end of the revolution connecting axle of slewing equipment by linkage, fixedlys connected with percussion mechanism in the lower end of described revolution connecting axle; The outside of described slewing equipment also is equipped with brake stretching device.
The sidewall of described revolution connecting axle is provided with oil-feed cannelure, fuel-displaced cannelure, air inlet cannelure; Also have the pipeline of distinguishing UNICOM with oil-feed cannelure, fuel-displaced cannelure, air inlet cannelure in its axis body, be respectively inflow pipeline, flowline, admission line; Described oil-feed cannelure, fuel-displaced cannelure, air inlet cannelure communicate with fuel feed hole, oil outlet, air inlet on the axle sleeve respectively; Wherein, inflow pipeline and flowline constitute the loop with the oil inlet pipe of percussion mechanism with flowline respectively and link to each other, and admission line washes air flue with silt on impacting head and links to each other.
Described brake stretching device by the brake rim, eight that the two sides has fixed mount support the interlock pieces, four oil cylinders are formed, the fixed mount of every brake rim is by upper and lower each two the lateral walls flexible connections of supporting interlock pieces and axle sleeve; The oil cylinder seat of described oil cylinder is movably connected on the axle sleeve, and two of the top of its piston boit and brake rim downside are supported the interlock piece and flexibly connect.
The invention has the beneficial effects as follows: because the brake stretching effect of brake stretching device, can be so that rotary impact hammer reaction force upwards obviously reduces; And the steel pipe casing can be avoided landslide, also can increase the impact force of rotary impact hammer.

Specific embodiment
A kind of rotary impact hammer of the present invention is made up of suspender 1, rotary power unit 2, linkage 3, mud suction pipe 5, percussion mechanism 6, slewing equipment 7, and described rotary power unit 2 is connected with the crane of construction operation by suspender 1 fixed thereon.Described rotary power unit 2 provides rotary power for a kind of rotary impact hammer of the present invention.Described percussion mechanism 6 provides downward impact power for a kind of rotary impact hammer of the present invention.Owing to ceaselessly rotate during a kind of rotary impact hammer work of the present invention, therefore need slewing equipment 7 to provide oil supply loop for percussion mechanism 6, and the gases at high pressure that are used for the silt flushing.
Described slewing equipment 7 is made up of revolution connecting axle 71, bearing 72, axle sleeve 73, is provided with bearing 72 between described revolution connecting axle 71 upper ends and the axle sleeve 73; Described rotary power unit 2 is fixedlyed connected with the upper end of the revolution connecting axle 71 of slewing equipment 7 by linkage 3, fixedlys connected with percussion mechanism 6 in the lower end of described revolution connecting axle 71.The sidewall of described revolution connecting axle 71 is provided with oil-feed cannelure 711, fuel-displaced cannelure 712, air inlet cannelure 713; Also have the pipeline of distinguishing UNICOMs with oil-feed cannelure 711, fuel-displaced cannelure 712, air inlet cannelure 713 in its axis body, be respectively inflow pipeline 714, flowline 715, admission line 716; Described oil-feed cannelure 711, fuel-displaced cannelure 712, air inlet cannelure 713 communicate with fuel feed hole 731, oil outlet 732, air inlet 733 on the axle sleeve 73 respectively.Wherein, inflow pipeline 714 and flowline 715 constitute the loop with the oil inlet pipe of percussion mechanism 6 with flowline respectively and link to each other, admission line 716 with impact silt on 62 and wash the air flue (not shown) that links to each other.
Described percussion mechanism 6 is by hydraulic impactor 61 and impact 62 and constitute, and impacts 62 front ends of being located at hydraulic impactor 61.Described hydraulic impactor 61 also is connected with the fueller formation loop of outside by the pipeline of slewing equipment 7.
The outside of described slewing equipment 7 also is equipped with brake stretching device 4.Described brake stretching device 4 by the brake rim 41, four that the two sides has fixed mount support interlock piece 42, two oil cylinders 43 are formed, the fixed mount of every brake rim 41 is by upper and lower each two the lateral walls flexible connections of supporting interlock pieces 42 and axle sleeve 73; The oil cylinder seat of described oil cylinder 43 is movably connected on the axle sleeve 73, and two of the top of its piston boit and brake rim 41 downsides are supported interlock piece 42 and flexibly connect.A kind of rotary impact hammer of the present invention in the time of if necessary, can strut brake stretching device 4 when work, brake rim 41 is supported on the inwall of steel pipe firmly, to increase a kind of impact force of rotary impact hammer.
Because a kind of rotary impact hammer of the present invention is a kind of excavator of automation, can water filling in steel pipe when its work, become silt after making impact.Therefore, described mud suction pipe 5, is extracted silt out when slush pump is worked through the bottom of the outside feeding steel pipe of hydraulic impactor 61 by pipeline.
