Abstract
The utility model discloses a hydraulic walking mechanism on a pile press machine. Under the premise of unchanged total walking thrust, the original single walking hydrocylinder on two long tracks and two short tracks, only acting on single lifting hydrocylinder, a walking trolley and a leg structure is changed into parallel walking hydrocylinders linked by double cylinders, simultaneously acting on two lifting hydrocylinders, walking trolleys and leg structures on the same track; besides, associated connection points are additionally provided with buffer devices. The utility model thus has the advantage of balance stress of the components, reduces the damaging effect caused by the on-off operation inertia of the pile machine to relevant stressed points, has high strength, high durability and simple structure, and breaks through the traditional mold for the walking mechanism of pile press machines in the class.
Description
The utility model relates to a kind of stride machinery, the hydraulic moving mechanism walking mechanism on the hydraulic static pile pressing machine in particularly a kind of constructional engineering machinery.
Whole hydraulic static pile pressing machine is to rely on its equipment self-weight to make the pile sinking counter-force pile cutoff is sunk, and therefore, complete machine weight is very heavy.Its walking mechanism is under the situation of the huge load of supporting complete machine, and the operations such as finishing vertical or horizontal walking and body rotation of still needing is a component part very crucial on this kind pile press.The walking mechanism of hydraulic static pile pressing machine generally includes two long shoes, two short carrying out, and length is carried out into rectangular arrangement; On carrying out, length have four jack-up hydraulic rams supporting body by long shoe chassis and leg structure body; The body base links with short carrying out by four short chassis of carrying out simultaneously; On length is carried out the walking hydraulic jack is housed, they are generally four.Its work crosses that to become be like this: four jack-up hydraulic rams actions on long the carrying out make the body short built on stilts of carrying out that rises.Body is carried on long the carrying out, two walking hydraulic jack horizontal operations on this duration is carried out, promote two directors and fulfil away chassis through two jack-up hydraulic ram bar heads, make jack-up hydraulic ram fairlead and piston thereof lateral stressed, and this thrust passed to two leg structure bodies, pass to body then, drive in addition that two walking carriages move passively thereby pass in addition two leg structure bodies and jack-up hydraulic ram by body.The walking mechanism of structure like this, its jack-up hydraulic ram and leg structure body are highly susceptible to damaging because of discontinuity equalization, and each tie-point is easy to be damaged because of the huge inertia that stake machine start-stop operation produces.
The purpose of this utility model is: by improving design, alleviate greatly and prevent the disadvantage that hydraulic moving mechanism walking mechanism jack-up hydraulic ram on the aforementioned existing pile press and leg structure body are easy to damage because of discontinuity equalization and each interface produces because of the start-stop of stake machine huge inertia goes to pot, thereby prolong the application life of jack-up hydraulic ram and walking mechanism.
The design concept of walking mechanism described in the utility model is like this: but but the characteristics of utilizing liquid direction transmitted power and UNICOM to work, under the constant prerequisite of total walking thrust, walk diameter walking hydraulic jack with four on original two long shoes and two short the carrying out and change eight minor diameters walking hydraulic jacks into.Soon only acted on single jack-up hydraulic ram originally, walking carriage, single major diameter walking hydraulic jack on the leg structure body changes into and acts on same last two jack-up hydraulic rams of shoe simultaneously respectively, twin-tub interlock walking in parallel hydraulic jack on walking carriage and the leg structure body, and at relevant interface position reload buffer device.Specifically be constructed as follows:
Two walking hydraulic jacks are arranged on same shoe, and they are walking hydraulic jack (3) and walking hydraulic jack (4); Four buffers are arranged, and they are two buffers (8), two buffers (9); The bar head (303) of walking hydraulic jack (3) links through this end buffer (8) with the point of attachment of this shoe structure one end; The bar head (403) of walking hydraulic jack (4) links through this end buffer (8) with the point of attachment of this shoe structure other end; Walking hydraulic jack (3) and the point of attachment of walking carriage (5) link through the buffer (9) at this position, and walking hydraulic jack (4) then with on this shoe is linked by the point of attachment of another walking carriage (5) of its promotion through the buffer (9) at this position; The rod chamber (301) of walking hydraulic jack (3) links through pipeline (1) with the rodless cavity (402) of walking hydraulic jack (4), and the rodless cavity (302) of walking hydraulic jack (3) links through pipeline (2) with the rod chamber (401) of walking hydraulic jack (4).
Through so improving the hydraulic moving mechanism walking mechanism on the described pile press after designing, owing to will only act on single jack-up hydraulic ram on this shoe on the original shoe, walking carriage, the single major diameter walking hydraulic jack of leg structure body changes into and acts on two jack-up hydraulic rams on this shoe simultaneously respectively, the twin-tub interlock walking in parallel hydraulic jack of walking carriage and leg structure body is so had the advantage of aforementioned each parts stress equalization; Owing to installed buffer additional, just alleviated of the destruction of stake machine start-stop operation inertia greatly to relevant stress point at the contact position that respectively is associated; As seen hydraulic moving mechanism walking mechanism described in the utility model has stress equalization, the intensity height, and advantage durable in use and simple in structure has broken through this type of machine stride walking mechanism traditional mode.
