Abstract
The invention relates to a large-scale combined-type heavy tamping machine for treating composite foundations, consisting of a tamping hammer, a hoisting part, a shifting part and a supporting part. The machine is characterized in that: the supporting part is a rigid upright framework consisting of four upright columns leaning inwards at a certain angle, a top plate and a base; the tamping hammer is connected with the hoisting part and positioned on a central position inside the framework. The supporting part is in a square quadrangular frustum pyramid structure with a small top and a big bottom, has the characteristic of inside hoisting, eliminates unstable factors produced by support rebound force, obviously reduces impact and shake, and overcomes the defect of using a crane arm for three-point type support. The shifting part adopts a widened and lengthened track and is controlled by a hydraulic system, which increases stability and safety and provides convenience for shifting-moving operation. A crawler crane is replaced with a hoist as a power part, which greatly reduces construction cost, guarantees safety and improves work efficiency.

Summary of the invention
Technical problem to be solved by this invention provides a kind of large-scale combined dynamic compaction machinery; The tamping force that solves existing rammer machine is little; The problem of poor stability, the present invention has also solved existing rammer machine and must rely on corollary equipment to be shifted and inefficient problem, and cost is low, be convenient to transportation.
Large-scale combined dynamic compaction machinery of the present invention; Form by hammer ram, lift portion, supporting part and displacing part; It is characterized in that said supporting part is four root posts of lean-in certain angle and the rigidity vertical frame of top board and base composition; Hammer ram connects lift portion, is positioned at the inside of frame center.
Major technique characteristics of the present invention are that supporting part has adopted square truncated rectangular pyramids formula, stressed, the up-small and down-big stability structure in four sides; Realized the design feature of inside center lifting; Eliminated and supported the destabilizing factor that bounce produces; Overcome with the crane armed lever and made the defective that the bikini supporting exists, can obviously reduce and impact and vibrations.
Said lift portion comprises hoist engine, suspension hook, assembly pulley, wire rope, and the hammer ram connecting shackle is installed assembly pulley on the top board of supporting part, and hoist engine is installed on the base, and hoist engine is connected with hammer ram through wire rope, assembly pulley, suspension hook.Connected mode between hoist engine and the hammer ram all can realize according to the known technology mode.On base, fixed pulley can be set, the effect of the fixed pulley of setting is to make things convenient for the wire rope on the hoist engine to be connected to the assembly pulley on the top board.Said suspension hook mode according to known technique is formed by connecting on detacher and pulley, and detacher connects hammer ram.
Said displacing part is made up of crawler belt and hydraulic control system, and crawler belt is installed on the base.
A kind of preferred concrete structure of the present invention is: lean-in 3～5 ° of four isometric columns of supporting part, and base is a rectangle, is positioned at the hoist engine that lift portion is installed by a side of rectangle minor face; Four root post lower ends are fixed on the base through connecting row's seat respectively, and four connection row seat points are located in the same horizontal plane, and 4 lines are formed a square; Top board is a square, and four root posts upper end is fixed on the top board through connecting row's seat respectively, and four connect row's seat point and are located in the same horizontal plane; 4 lines are formed a square, and the base minor face is installed the crawler belt of displacing part, and the hydraulic operating system of crawler belt is placed in a side of the corresponding hoist engine of rectangle minor face; A day beam is installed on the top board; Assembly pulleys are overlapped in configuration two above, and wherein the center of middle assembly pulley overlaps the hammer ram connecting shackle with the diagonal of top board; Hoist engine is connected with hammer ram through wire rope, assembly pulley, suspension hook, and hoist engine, suspension hook, assembly pulley, wire rope constitute lift portion.
Advantage of the present invention:
1, displacing part has adopted the crawler belt design of widening, and has strengthened the contact area of equipment, has played firm effect; Simultaneously, strengthened the firm of equipment more and stablized with the part (two minor face) of crawler belt part, with the walking and the displacement of hydraulic control crawler belt as the chassis; Reliable in action; Strengthen the stable and safety of equipment, improved efficient, improved the application life of equipment simultaneously.
2, lift portion has adopted hoist engine to replace crawler crane, and is easy to operate, reliable, improved the application life of equipment and the reliability of operation, and increased lifting force, and technical ability is rammed in raising that can be very big.
3, support section adopts four root posts of introversion certain angle and the rigidity vertical frame that last top and bottom seat is formed, and has realized the inside center lifting, has eliminated and has supported the destabilizing factor that bounce produces, and obviously reduces and impacts and vibrations.
