Abstract
The utility model relates to a portal frame type special heavy-tamping machine comprising a walking part, a lifting part, a power part, a bracket part and an auxiliary turning part, wherein the bracket part is formed by connecting a main rod, two secondary rods, a balance beam and a combined platform by cross shafts (or hinge shafts), and the balance beam is respectively connected with the two secondary rods by pin shafts and is connected with the main rod by the cross shafts. The combined platform is in a shape like a Chinese character 'mu', and the size of the combined platform can be changed according to a space between tamping points of heavy tampers; the projection of the balance beam is in the center of the combined platform; in the auxiliary turning part, two side surfaces of the combined platform near tracks are respectively provided with an auxiliary turning jack to support the tracks of one side, and the tracks of the other side are used for turning in an large angle; a fixed pulley set of the lifting part is arranged on the main rod, and the pulley edges of the pulleys approach a center line of the side surface of the main rod to reduce the torque of the main rod.
Description
Technical field
The utility model belongs to technical field of engineering machinery, is used for the dynamic consolidation construction of geotechnical engineering.
Technical background
In dynamic consolidation construction, people generally adopt crawler crane+portal frame as dynamic consolidation construction machinery now.In dynamic consolidation construction, the type selecting of crawler crane is to determine according to the strong energy level that rams, and rams in that the above high level of 8000kN.m is strong, and what select for use all is crawler crane more than 50 tons, and the portal frame sectional dimension is big, and weight is also big.In the construction after finishing a tamping point, first loose-back rope, reversing back, pull back hammer ram, tighten up back of the body rope, promote portal frame, it is in place to carry hammer ram again, manually portal frame is pushed open, carries hammer, the loose-back rope, reversing begins to ram its process operations complexity, to driver's technical requirements height, often occur owing to hurting sb.'s feelings and overturn accident that mismate causes.Tamping point is arranged by matrix-style, when dynamic compaction machinery is changed between the tamping point line-spacing in the construction, limited by the place, problems such as crawler belt derailing, supporting wheel shaft fracture, crawler belt fracture takes place easily, and wasted the working time greatly.Pivot turn needs very strong driving force again, and the rated power of crawler crane motor is demarcated by turning power.In construction, portal frame need be installed on the crawler crane keeping its stability, and often occurs causing overturn accident because of the portal frame unstability under uneven on construction ground, the situation such as sink.Present existing special-purpose dynamic compaction machinery does not all break away from crawler crane, can not fundamentally solve stability problem, has just unilaterally strengthened the lifting performance of crane.
Summary of the invention
In order to increase work efficiency, simplify working programme, avoid the generation of overturn accident, the utility model is directly installed on support section on the crawler belt by combined platform, platform be " order " and font, hammer ram just in the middle of combined platform realization ram the place.After finishing a tamping point, mention the hammer ram telephone-moving to next tamping point, hammer ram is in the center of dynamic compaction machinery all the time, the serious consequences such as overturning of having avoided unstability to bring.
The technical scheme that its technical problem that solves the utility model adopts is:
The special-purpose dynamic compaction machinery of gantry type is made up of running gear, lift portion, power section, holder part and auxiliary turn fractions.
Running gear is made up of two crawler belts, and crawler belt provides power by motor or hydraulic motor.
Lift portion is by elevator, wire rope, and the fixed pulley group, running block and detacher are formed.Fixed pulley group wherein is installed on the main club head position, and the pulley wheel that makes the fixed pulley group is along on the center line of close mobile jib side, and hammer ram swing and ground injustice can be to the torque influence that applies of mobile jib like this.
Power section is made of motor or motor.
Holder part is formed by connecting by cross axle (or hinge) by a mobile jib, two secondary bars, equalizer bar and a cover combined platform.Equalizer bar is connected with two secondary bars respectively by bearing pin, and equalizer bar is connected with mobile jib by cross axle, and combined platform is connected with two secondary bars respectively by cross axle, and combined platform is connected with mobile jib by bearing pin.Combined platform becomes " order " font, can change the combined platform size according to the size of strong rammer grid spacing, because normally do not pass through when grid spacing hour has very much the tamping pit of timely backfill to influence the rammer machine.One section bridge type beam in combined platform its objective is the part terrain clearance of increasing dynamic compaction machinery, and being convenient to dynamic compaction machinery can stride across hammer ram smoothly, brings convenience to installation, maintenance.Holder part of the present utility model is not a rigid frame, connects by bearing pin between each member.Ground is uneven and partly sink to causing the combined platform distortion, causes the weld bond cracking in rigid system easily, and the bearing pin connected system has then effectively been avoided weld bond cracking problem.
Auxiliary turn fractions is to be equipped with an auxiliary turning jack respectively in two sides of the close crawler belt of combined platform, when wanting wide-angle to turn, start the jack of an end, jack props up on the ground by rotary disk, make the crawler belt of this side almost liftoff, the weight of almost half of whole rammer machine concentrates on the jack, the crawler belt of opposite side will make complete machine center on jack by walking and do arcuate movement, realize easily turning to, finish and turn to the back to regain jack and rotary disk, use auxiliary turning of jack to greatly reduce turning moment, saved power, improved the application life of crawler belt.
The beneficial effects of the utility model are: simple in structure, the resistance to overturning of dynamic compaction machinery has been strengthened in the mobile flexibility that has improved dynamic compaction machinery, has improved operating efficiency.
