Description
Technical field
The utility model relates to excavator device, and specifically a kind of hydraulic power accumulator fills energy device.
Background technique
Current common excavator does not generally reclaim and stores energy-producing device in working procedure, particularly swing arm is in decline process, huge potential energy not only can not be utilized effectively, also can cause in-fighting on the contrary, if can research and develop a kind of equipment that reclaims this energy, used, can greatly be raised the efficiency, reduced energy consumption.Simultaneously on market general accumulator fill can time need special-purpose the filling can frock, utilize the trouble relatively that seems on excavator, for this phenomenon, research and develop a kind of hydraulic power accumulator and fill and can seem particularly important by device.
Notice of authorization CN202056123U, notice of authorization day 2011.11.30 Patent Application Publication a kind of potential energy of shear leg deadweight that utilizes reclaim accumulator, comprise shear leg, the below of shear leg is provided with energy and reclaims oil cylinder, shear leg is connected with the push rod that energy reclaims oil cylinder, and energy reclaims oil cylinder and connects accumulation of energy storage through oil pipe.In accumulation of energy storage, bottom is hydraulic oil, and top is for there being pressure air.Energy reclaims oil cylinder and all by oil pipe, is connected with hydraulic power unit with accumulation of energy storage, and hydraulic power unit provides hydraulic oil for energy recovery oil cylinder and accumulation of energy storage.The defects such as although above-mentioned open file has been equipped with a kind of accumulator, potential safety hazard, easily appears in this theoretic being provided in practice, and exists application inconvenient, not intelligent.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic power accumulator to fill can device, can fill can reach setting pressure time and automatically cut off power source at accumulator, safe and efficient.
The purpose of this utility model can realize by following technical solution:
This hydraulic power accumulator fills and can comprise accumulator, main pump by device, and described accumulator is connected with main pump by main valve, Bonding pressure cut-off valve between described accumulator and main valve.
The purpose of this utility model also can realize by following technical solution:
Further, this hydraulic power accumulator fills and can also comprise pilot handle by device, and described pilot handle is connected with pressure shut-off valve, main valve, main pump respectively.
Further, this hydraulic power accumulator fills described in can device and assembles one-way valve between accumulator and pressure shut-off valve.
Compared to prior art, the utlity model has following beneficial effect:
The utility model can fill can reach setting pressure time and automatically cut off power source at accumulator, safe and efficient.Through the test of excavator embarkation, filling can be fully, and rapidly and efficiently, easy to operate, energy storage pressure requirement up to specification, can meet the energy requirement that swing arm rises completely, is the important guarantee means that realize energy-conservation excavator.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that hydraulic power accumulator of the present utility model fills energy device.
In figure: accumulator 1, pressure shut-off valve 2, main valve 3, pilot handle 4, main pump 5.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, yet accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
With reference to accompanying drawing 1, this hydraulic power accumulator fills and can comprise accumulator 1, main pump 5 by device, and described accumulator is connected with main pump by main valve 3, Bonding pressure cut-off valve 2 between described accumulator and main valve.Also comprise pilot handle, described pilot handle 4 is connected with pressure shut-off valve, main valve, main pump respectively.Between described accumulator and pressure shut-off valve, assemble one-way valve.
When excavator is normally worked, when accumulator 1 energy is owing to rising or other consumption for swing arm, when its pressure requires lower than regulation, need fill can, now pilot handle 4 is pushed into and fills energy position, pilot signal is passed to main valve 3, pressure shut-off valve 2, and main pump 5 is communicated with accumulator 1 hydraulic circuit, main pump 5 is delivered to hydraulic oil in accumulator 1, and accumulator 1 starts to fill energy.When accumulator 1 pressure constantly increases, while finally reaching authorized pressure value, pressure shut-off valve 2 is closed with the hydraulic circuit that accumulator 1 is connected, and accumulator completes and fills energy.Hydraulic oil flows back to fuel tank by pressure shut-off valve 2 another oil circuits.Now pilot handle 4 is resetted, when accumulator 1 fills can be complete.Circulation successively.
The utility model hydraulic power accumulator fills energy device, and when accumulator 1 fills energy, when energy storage pressure reaches designing requirement, pressure shut-off valve 2 cuts off oil hydraulic circuit, and accumulator 1 stops filling energy.Through the test of excavator embarkation, filling can be fully, and rapidly and efficiently, easy to operate, the requirement up to specification of accumulator 1 pressure, can meet the energy requirement that swing arm rises completely, is the important guarantee means that realize energy-conservation excavator.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
