Description
Technical field
The utility model relates to a kind of folder stake oil hydraulic cylinder, and refering in particular to is a kind of energy-storage type folder stake oil hydraulic cylinder that is used on the static pile press.
Background technique
Folder stake oil hydraulic cylinder is important constituent element on the static pile press, be directly connected to the working life of equipment, the problems such as efficient of work, the folder stake oil hydraulic cylinder of existing static pile press is when work, after starting oil pump, after system pressure arrives setting pressure, operation folder stake multi-way valve, push folder stake position to, hydraulic oil enters folder stake oil cylinder piston rod is released, driving anchor clamps holds precast pile tightly, by Pilot operated check valve retaining clip compaction forces, by piling mechanism stake is pressed in the soil then, after finishing, the operation multi-way valve is pushed pine stake position to, hydraulic oil enters folder stake oil cylinder piston rod is advanced, anchor clamps are unclamped, carry out folder stake next time again, but a folder stake oil cylinder is arranged in the piling process as long as problem is a system, perhaps valve leaks, folder stake pressure will descend at once, and stake just folder is not tight, will reveal sliding stake, equipment is sustained damage, present solution is to lean on the site operation personnel by the frequent multi-way valve operating grip that promotes, makes a folder cylinder often be in a folder stake position resolution system and leaks, but owing to system leak more or less exists, and frequent operation also brings a lot of inconvenience to the operator, influences the working life of machine simultaneously.
The model utility content
The novel purpose of this use is to overcome the deficiency of prior art and a kind of simple in structure, long service life, high working efficiency are provided, solve in folder stake process pressure effectively and descend and cause the not energy-storage type folder stake oil hydraulic cylinder of tight phenomenon of pile holder.
The purpose of this utility model is achieved by following technical proposals:
A kind of energy-storage type folder stake oil hydraulic cylinder, comprise oil cylinder, pressure gauge, Pilot operated check valve, one end of described filler opening connects the oil inlet pipe of described Pilot operated check valve, the oil outlet tube of described Pilot operated check valve is connected with pressure gauge with the oil inlet pipe of oil cylinder respectively, the oil outlet tube of described oil cylinder is connected with oil outlet, is connected with accumulator between described Pilot operated check valve and the described oil cylinder.
In the utility model, connect with a three-way pipe between described Pilot operated check valve, accumulator and the oil cylinder, an end of three-way pipe is connected with the oil outlet tube of Pilot operated check valve, and the other end connects the oil inlet pipe of oil cylinder, is connected with accumulator on the third through-hole of three-way pipe.
Owing to adopt above-mentioned scheme, described accumulator is installed between Pilot operated check valve and the oil cylinder, be used for storing fluid potential energy, when oil cylinder needs oil pressure hour, the pressure oil part supply system of pump output, and remaining part transfers to accumulator and stores, when system needs high-pressure high-flow, accumulator just with pump jointly to the oil cylinder fuel feeding, obtain the big and high working oil of oil pressure of flow in the short time than the independent supply of oil pump, satisfy the need of work of oil cylinder, guaranteed the stable of folder stake pressure.
Advantages such as described model utility---a kind of energy-storage type folder stake an oil hydraulic cylinder has simple in structure, and long service life, high working efficiency, folder stake are stable, firm are suitable for the improvement of a folder oil hydraulic cylinder on the static pile press of various models.
Description of drawings

In the accompanying drawing, 1----oil cylinder, 2----pressure gauge, 3----accumulator, 4----Pilot operated check valve, 5----filler opening, 6----oil outlet.
Embodiment
Below in conjunction with accompanying drawing, describe the embodiment of energy-storage type folder stake oil hydraulic cylinder in detail
As shown in the figure, a kind of energy-storage type folder stake oil hydraulic cylinder, comprise oil cylinder 1, pressure gauge 2, Pilot operated check valve 4, one end of described filler opening 5 connects the oil inlet pipe of described Pilot operated check valve 4, the oil outlet tube of described Pilot operated check valve 4 is connected with pressure gauge 2 with the oil inlet pipe of oil cylinder 1 respectively, the oil outlet tube of described oil cylinder 1 is connected with oil outlet 6, is connected with accumulator 3 between described Pilot operated check valve 4 and the described oil cylinder 1.
In the utility model, connect with a three-way pipe between described Pilot operated check valve 4, accumulator 3 and the oil cylinder 1, one end of three-way pipe is connected with the oil outlet tube of Pilot operated check valve 4, and the other end connects the oil inlet pipe of oil cylinder 1, is connected with accumulator 3 on the third through-hole of three-way pipe.
During use, after starting oil pump, the oily flow that needs when oil cylinder 1 hour, the pressure oil part of pump output is supplied with oil cylinder 1, and remaining part transfers to accumulator 3 and stores, after oil cylinder 1 pressure arrives setting pressure, hydraulic oil enters oil cylinder 1 piston rod is released, drive anchor clamps precast pile is held tightly, in holding the process of precast pile tightly, on the one hand by Pilot operated check valve 4 retaining clip compaction forces, accumulator 3 and pump are jointly to the oil cylinder fuel feeding on the other hand, can obtain the big and high working oil of oil pressure of flow at short notice, also guarantee the stability of folder stake pressure, by piling mechanism stake is pressed in the soil then than the independent supply of oil pump, after finishing, hydraulic oil enters folder stake oil cylinder 1 piston rod is advanced, and anchor clamps are unclamped, and carries out folder next time again.
