Abstract

The utility model provides a kind of potential energy recovery hydraulic means, including oil-filled hydraulic system, energy storage equipment, main hydraulic system, oil cylinder, load G, it is characterized in that, the main hydraulic system connects oil-filled hydraulic system, energy storage equipment and oil cylinder respectively, and the oil cylinder includes A mouths and B mouths, the oil cylinder and with load G be connected, oil pump, line filter, check valve, normally opened manual ball valve are cascaded structure in the oil-filled hydraulic system, and the energy storage equipment includes accumulator, and the main hydraulic system includes 22 logical proportionality velocity modulation stop valves.The utility model stores potential energy caused by the load decline of load elevating control hydraulic system into hydraulic energy, hydraulic energy is discharged again when load needs and risen, load is promoted to rise, the utility model causes hydraulic system installed power to reduce, caloric value reduces, so whole hydraulic system efficiency high, compared with traditional control system, is saved up to 40% or so.

Description

A kind of potential energy reclaims hydraulic means
Technical field
The utility model relates to a kind of recovery potential energy, compact-sized hydraulic means, specifically a kind of potential energy recovery Hydraulic means.
Background technology
Largely exist with potential energy plant equipment in the production of modernization, and energy during potential energy release is wasted, The load of load elevating control hydraulic system in the stepping beam type transportation system that metallurgy industry largely uses at present declines control Generally using balance throttling control, potential energy when load declines is converted into heat energy and is discharged into hydraulic system, system heat generation amount Greatly, the cooling power of consumption is big.Whole hydraulic system efficiency is low, and energy-conservation and environmental protection now is global economic development to energy source device Basic demand, advocate energy-conservation with environmental protection into the new century theme, in order to solve this problem, there is provided a kind of new technical side Case.
Utility model content
In order to solve the above problems, the utility model provides a kind of potential energy recovery hydraulic means.
Technical scheme provided by the utility model:A kind of potential energy reclaims hydraulic means, including oil-filled hydraulic system, accumulation of energy dress Put, main hydraulic system, oil cylinder, load, main hydraulic system connects oil-filled hydraulic system, energy storage equipment and oil cylinder, oil cylinder bag respectively Include A mouths and B mouths, oil cylinder and be connected with load, oil pump, line filter, check valve, normally opened manual ball in oil-filled hydraulic system Valve, it is cascaded structure, energy storage equipment includes accumulator, and main hydraulic system includes 22 logical proportionality velocity modulation stop valves.
Further, 22 logical proportionality velocity modulation stop valves include 22 logical I, 22 logical ratios tune of proportionality velocity modulation stop valve Fast II, 22 logical proportionality velocity modulation stop valve III of stop valve, described 22 logical proportionality velocity modulation stop valves I control the A of main hydraulic system Mouthful, described 22 logical proportionality velocity modulation stop valves II control the B1 mouths of main hydraulic system, described 22 logical proportionality velocity modulation stop valves III Control the B2 mouths of main hydraulic system.
The beneficial effects of the utility model are:The utility model is that mechanical potential is changed into hydraulic energy and stored again Utilize, potential energy caused by the load decline of load elevating control hydraulic system is stored into hydraulic energy, works as load Needing again to discharge hydraulic energy when rising, promote load to rise, the utility model causes hydraulic system installed power to reduce, Caloric value reduces, so whole hydraulic system efficiency high, compared with traditional control system, is saved up to 40% or so.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is structure chart of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1-2, a kind of potential energy recovery hydraulic means, including oil-filled hydraulic system, energy storage equipment, main hydraulic pressure system System, oil cylinder(7), G is loaded, main hydraulic system connects oil-filled hydraulic system, energy storage equipment and oil cylinder respectively(7), oil cylinder includes A mouths With B mouths, oil cylinder(7)It is connected with load G, oil pump in oil-filled hydraulic system(1), line filter(2), check valve(3), it is normally opened Manual ball valve(4)For cascaded structure, energy storage equipment includes accumulator(6), main hydraulic system includes 22 logical proportionality velocity modulations cut-offs Valve(5), 22 logical proportionality velocity modulation stop valves(5)Including 22 logical I, 22 logical proportionality velocity modulation stop valves of proportionality velocity modulation stop valve IIth, 22 logical proportionality velocity modulation stop valves III, 22 logical proportionality velocity modulation stop valves I control the A mouths of main hydraulic system, 22 logical ratios Speed governing stop valve II controls the B1 mouths of main hydraulic system, and 22 logical proportionality velocity modulation stop valves III control the B2 mouths of main hydraulic system, B1, B2 mouth of main hydraulic system are connected with oil cylinder B mouth.
Operation principle is as follows:Preparation before work, the hydraulic oil that oil pump 1 pumps out is by line filter 2, unidirectional Valve 3, the A chambers from proportionality velocity modulation stop valve 5.1 to oil cylinders 7 and accumulator 6 of normally opened manual ball valve 4,22 logical are oil-filled, until reaching negative Carry the operating pressure of G requirements.
The course of work, if the load of hydraulic jack 7 is G, the B chambers of hydraulic jack 7 pressure and load G from recast During with decline, the hydraulic oil of the A chambers of hydraulic jack 7 is pressed by 22 logical proportionality velocity modulation stop valves I, normally opened manual ball valves 4 Accumulator 6 is retracted, the pressure energy for loading G potential energy and the B chambers of hydraulic jack 7 is stored in accumulator 6, passes through 22 logical ratios Example speed governing stop valve III controls load G decrease speed.When load G needs to rise, control valve I and II is opened, is stored up in accumulator 6 The hydraulic energy deposited is released, and promotes load G to rise, and the upper raising speed for loading G is controlled by 22 logical proportionality velocity modulation stop valves I Degree.
