Description
Technical field
The present invention relates to fluid pressure type static pile press field, specifically, relate to a kind of pile clamping box of accurate positioning, belong to the parts of the clamping pile body of fluid pressure type static pile press.
Background technology
Pile clamping box is one of core component of static pile press, and its work characteristics is that chucking power is big, operating frequency is high.Its basic structure is made up of casing, cylinder sleeve, folder stake oil cylinder, pile-clamp and fixed head 5.As shown in Figure 1: pile clamping box is general to be divided two-layerly up and down, and every layer all has four cylinder sleeves by the uniform (see figure 2) in casing center, and the center of four cylinder sleeves is on same plane, and cylinder sleeve is welded on the casing.Folder stake cylinder tube cylindrical cooperates with cylinder sleeve, can only press from both sides piston rod location bottom cylinder sleeve of stake oil cylinder along the cylinder sleeve rectilinear motion, and is fixed on the cylinder sleeve by the screw field by fixed head.Pile-clamp is installed in folder stake cylinder tube bottom, is screwed.During pile clamping box work, system pressure oil enters all folder stake oil cylinder rodless cavities, and cylinder tube stretches out, and drives pile-clamp to pile clamping box center clamping work pieces (pile body).At work, jaw that need be produced by the clamping cylinder clamping force and the frictional force between the workpiece just reach the hundreds of ton even go up kiloton, and the folder pile holder is tight, only two, three minutes just once for the frequency of break cycle.These work characteristics of pile clamping box just require all jaws when clamping on the same face of cylinder, yet because the resistance distance and the flowed friction different, oil pipe of oil cylinder itself is also inequality, thus cause gnaw when oil cylinder is asynchronous to cause jaw to clamp into pile body even folder split, pinch off pile body (quick-fried).Existing producer adopts the speed that adds flow speed control valve or choke valve adjustment folder stake oil cylinder, and this method has two shortcomings: the first, and so the heavy wool cylinder can not be transferred to synchronously; The second, it is very big to increase the downstream pressure loss.
Summary of the invention
The pile clamping box that the purpose of this invention is to provide a kind of accurate positioning, pile-clamp is on same cylinder locating surface in the time of guaranteeing each the clamping.
The technical scheme that realizes above-mentioned purpose is: a kind of pile clamping box of accurate positioning, by casing, cylinder sleeve, folder stake oil cylinder, pile-clamp, fixed head and hydraulic circuit are formed, hydraulic circuit comprises fuel tank, oil pump, overflow valve, hand-operated valve and hydraulic control one-way valve, fixed head is fixed on the cylinder sleeve, folder stake oil cylinder is communicated with hydraulic circuit, the cylinder barrel of folder stake oil cylinder cooperates with cylinder sleeve, cylinder sleeve is welded on the casing, folder stake oil cylinder is by two-layer distribution, four every layer, every layer folder stake oil cylinder is divided into two gulde edge oil cylinders and two gripper edge oil cylinders, the locating surface of two gulde edge oil cylinders is H1 to the distance at casing center, the locating surface of two gripper edge oil cylinders is H2 to the distance at casing center, and H1 is greater than H2; Be in series with sequence valve and one way valve in parallel on the hydraulic circuit.
After adopting technique scheme, the locating surface of two gulde edge oil cylinders is H1 to the distance at casing center, and the locating surface of two gripper edge oil cylinders is H2 to the distance at casing center, and H1 is greater than H2; Improve back gulde edge oil cylinder like this when piston rod all stretches out, the circular arc of pile-clamp just overlaps with the pile body cylindrical;
Owing on original hydraulic circuit, be in series with sequence valve and one way valve in parallel, sequence valve can guarantee that when clamping action gulde edge oil cylinder stretches out the position accurate positioning workpiece earlier, clamp by the gripper edge oil cylinder again, adopted the first method that afterwards clamps of locating, pile-clamp is on same cylinder locating surface when guaranteeing each the clamping.And unclamping one-way valve opens when moving, all folder stake oil cylinders can be withdrawn simultaneously, thereby raise the efficiency.

Among the figure 1, casing 2, cylinder sleeve 3, a folder stake oil cylinder 4, pile-clamp 5, fixed head 6, jaw extended position 7, jaw retracted position 8, pile body 9, gulde edge oil cylinder 10, gripper edge oil cylinder 11, fuel tank 12, oil pump 13, overflow valve 14, hand-operated valve 15, hydraulic control one-way valve 16, sequence valve 17, one way valve.
The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
As Fig. 3,4, shown in 6, a kind of pile clamping box of accurate positioning, by casing 1, cylinder sleeve 2, folder stake oil cylinder 3, pile-clamp 4, fixed head 5 and hydraulic circuit are formed, hydraulic circuit comprises fuel tank 11, oil pump 12, overflow valve 13, hand-operated valve 14 and hydraulic control one-way valve 15, fixed head 5 is fixed on the cylinder sleeve 2, folder stake oil cylinder 3 is communicated with hydraulic circuit, the cylinder barrel of folder stake oil cylinder 3 cooperates with cylinder sleeve 2, cylinder sleeve 2 is welded on the casing 1, folder stake oil cylinder 3 is by two-layer distribution, four every layer, every layer folder stake oil cylinder 3 is divided into two gulde edge oil cylinders 9 and two gripper edge oil cylinders 10, the locating surface of two gulde edge oil cylinders 9 is H1 to the distance at casing 1 center, and the locating surface of two gripper edge oil cylinders 10 is H2 to the distance at casing 1 center, and H1 is greater than H2; Be in series with sequence valve 16 and one way valve 17 in parallel on the hydraulic circuit.Hand-operated valve 14 is a three-position four-way valve.
The course of work of the present invention is as follows:
As shown in Figure 4, when hand-operated valve 14 pushes the 3 rodless cavity oil-feeds of folder stake oil cylinder, sequence valve 16 and one way valve 17 sealings, the 10 not oil-feeds of rodless cavity of gripper edge oil cylinder, the 9 rodless cavity oil-feeds of gulde edge oil cylinder, the pile-clamp 4 of gulde edge reaches jaw extended position 6, and gulde edge oil cylinder 9 strokes put in place, and the pile-clamp 4 of gulde edge is with pile body 8 location.At this moment system oil pressure is increased to setting value, and sequence valve 16 is opened, and gripper edge oil cylinder 10 just begins oil-feed, and the pile-clamp 4 of gripper edge reaches jaw extended position 6 and clamps pile body 8; When hand-operated valve 14 pushed the oil-feed of folder stake cylinder rod chamber, one way valve 17 was opened, all together withdrawals of folder stake oil cylinder 3, and all pile-clamps 4 are together got back to jaw retracted position 7, have saved the time like this, have improved efficient.
