A piston rod is arranged in the inner long cylinder, an oil inlet hole is formed at one end of the inner long cylinder provided with the slide valve, and an oil guide hole corresponding to the oil inlet hole is formed on the slide valve. An oil inlet port and a control oil port are respectively arranged on the outer long cylinder, the oil inlet port corresponds to the oil inlet hole, a hollowed area with small top and large bottom is arranged on the slide valve at the position of the oil guide hole, and the control oil port is arranged at the lower end of the slide valve. The hydraulic oil cylinder structure can fast lift the piston rod, falls in a free falling mode to drive a pile hammer to fast hammer a pile cap, is convenient to control and small in noise, and has a good effect when being applied to the pile driver.
Description
Technical field
The present invention relates to a kind of piling machinery, relate in particular to the hydraulic jack structure of pile driver.
Background technique
Piling work is at bridge, building waits in the construction, it is a traditional operation, wherein hydraulic pile hammer is a present comparatively ripe pile driving equipment, at present, the multidigit diesel pile hammer of domestic employing, Static pressure pile driver and a spot of but active force hydraulic pile hammer, diesel hammer is owing to produce waste gas in construction, the restriction that noise and vibration are subjected to greatly, Static pressure pile driver bulky, there is the transition high shortcoming of cost of transportation and seldom is used, its hammer force of the hydraulic pile hammer that nonoculture is exerted oneself is less, and exists bigger noise to be difficult to be promoted in municipal construction.
Summary of the invention
In view of the deficiency that background technique exists, the technical problem to be solved in the present invention provides a kind of simple in structure, the hydraulic jack structure of the hydraulic pile driver that noise is little and practical.
For this reason, the present invention takes following technological scheme to realize: a kind of hydraulic jack structure of hydraulic pile driver, it is characterized in that comprising foreign minister's cylinder, interior long cylinder, long cylinder places in described foreign minister's cylinder in described, long cylinder is communicated with oilhole with an end of foreign minister's cylinder in described, the other end connects by guiding valve, be provided with piston rod in the long cylinder in described, the end that described interior long cylinder is provided with guiding valve is provided with oil inlet hole, be provided with the oil guiding hole corresponding with described oil inlet hole at guiding valve, and be respectively equipped with filler opening and control port at foreign minister's cylinder, the corresponding setting with described oil inlet hole of described filler opening, be provided with the oil guiding hole place at described guiding valve and be provided with up-small and down-big hollow out zone, described control port is in the lower end of described guiding valve.
Be respectively equipped with high-voltage energy storage device and low pressure accumulator on described foreign minister's cylinder, be respectively equipped with high-pressure inlet and the low pressure inlet corresponding with described high-voltage energy storage device and low pressure accumulator on the long cylinder in described, be provided with and the corresponding low pressure oil guiding hole of low pressure inlet at described guiding valve.
The present invention is simple in structure, by the control of control port, can rise rapidly to piston rod, and the mode by freely falling body falls, and moves the quick hammering pile cover of pile hammer, and it controls convenient, and noise is little, is used for pile driver, has good effect.
Description of drawings
Further describe relevant details of the present invention below more by reference to the accompanying drawings.
Fig. 1 is structural drawing of the present invention;
Fig. 2 is the enlarged view at Fig. 1 M of the present invention place.
Embodiment
With reference to accompanying drawing, the hydraulic jack structure of this hydraulic pile driver, comprise foreign minister's cylinder 2, interior long cylinder 3, long cylinder 3 places in described foreign minister's cylinder 2 in described, long cylinder 3 is communicated with oilhole 1 with an end of foreign minister's cylinder 2 in described, the other end connects by guiding valve 15, be provided with piston rod 4 in the long cylinder 3 in described, and piston rod 4 connects pile monkey 16, the end that described interior long cylinder 3 is provided with guiding valve 15 is provided with oil inlet hole 10, be provided with the oil guiding hole 11 corresponding with described oil inlet hole 10 at guiding valve 15, and be respectively equipped with filler opening 7 and control port 14 at foreign minister's cylinder 2, described filler opening 7 and described oil inlet hole 10 corresponding settings are provided with oil guiding hole 10 places at described guiding valve 15 and are provided with up-small and down-big hollow out zone 12, and described control port 14 is in the lower end of described guiding valve 15.Be respectively equipped with high-voltage energy storage device 6 and low pressure accumulator 5 on described foreign minister's cylinder 2, be respectively equipped with the low pressure inlet 8 corresponding with low pressure accumulator 5 in described on the long cylinder 3, the import of its graceful accumulator 6 is corresponding with filler opening 7 on the interior long cylinder 3, is provided with and low pressure inlet 8 corresponding low pressure oil guiding holes 9 at described guiding valve 15.
The present invention carries out following work: the present invention is when work, its filler opening 7 is in the oil-feed state always, when needs rise pile monkey be, open solenoid valve, namely open control port 14, space 13 fuel feeding between control port 14 inside long cylinders 3 and the foreign minister's cylinder 2, after bringing up to certain oil pressure, to promote guiding valve 15, after guiding valve 15 moves, oil guiding hole 11 on its guiding valve 15 is communicated with the filler opening 7 on the oil inlet hole 10 on the interior long cylinder 3 and the foreign minister's cylinder 2 and the oil inlet hole 10 on the interior long cylinder 3 respectively with high-voltage energy storage device 6, at this moment, filler opening 7 inside long cylinder 3 fuel feeding, simultaneously, high-voltage energy storage device 6 also inwardly long cylinder 3 pressure is provided, in the interior piston rod 4 of long cylinder 3 with pile monkey 16 under the dual-pressure of hydraulic pressure and high-voltage energy storage device, rise rapidly, rise to predeterminated position, disconnect solenoid valve, it is closing control hydraulic fluid port 14, because control port 14 is closed, interior long cylinder 3 herein just diminishes with space 13 pressure that foreign minister's cylinder 2 forms, and owing to be provided with up-small and down-big hollow out zone 12 at oil guiding hole 11 places of guiding valve 15, so, after control port 14 is closed, there is pressure difference in the two ends up and down in hollow out zone 12, the pressure that high-voltage energy storage device 6 and filler opening 7 are come in just promotes guiding valve 15 downwards, thereby cutoff high accumulator 6, the passage of filler opening 7 and interior long cylinder 3, at this moment, pile monkey 16 is just to fall, simultaneously, guiding valve 15 cutoff high accumulators 6, behind the passage of filler opening 7 and interior long cylinder 3, low pressure oil guiding hole 9 on the guiding valve 15 is communicated with by low pressure inlet 8 interior long cylinder 3 with the inner chamber of foreign minister's cylinder 3, be communicated with low pressure accumulator 5 simultaneously, hydraulic oil in the interior long cylinder 3 flow in foreign minister's cylinder 2 by low pressure inlet 8, under the effect of low pressure accumulator 5, piston rod 4 tops of this hydraulic oil long cylinder 3 in oil-through hole 1 flow into, piston rod 4 had pressurization, so, pile monkey 16 the pressurization of hydraulic oil with and the double action of gravity under, hammering is driven piles at pile cover rapidly, its hammer force is big, noise is little, has good using effect.
