Abstract
A digital display device for hydraulic jack load comprises a pedestal, a large oil cylinder of a large piston provided on the pedestal, a small oil cylinder provided with a small piston, an oil tank outside the large oil cylinder, a high-pressure oil pipeline provided with a one-way valve and between one end of the small oil cylinder and the large oil cylinder, an oil pipeline provided with a one-way valve and a load-off valve between the oil tank and the other end of the small oil cylinder. The pedestal is also provided with a high-pressure oil pipeline that one end is communicated with the large oil cylinder and the other end part is provided with a pressure sensor, and the output end of the pressure sensor and the input end of the digital display host equipped on the pedestal form the electrical connection through cable. The digital display device for hydraulic jack load in the utility model can be steadily displayed with digital method, which is convenient for operating personnel to effectively master the process control, and is suitable for the use in machine manufacturing or maintenance industry and other operating occasions.
Description
Technical field:
The utility model relates to a kind of hydraulic jack, particularly relates to a kind of hydraulic jack load numeric display unit.
Background technology:
Along with science and technology development, the lifting that process industry is also maked rapid progress, thus, the application of hydraulic jack also more and more widely, sometimes, the load value in hydraulic jack when work manifest right and wrong with ordinary, and the load value when holding hydraulic jack work in order to support, on hydraulic jack, used at present traditional mechanical type pointer gauge, though, be the load value that has solved in the time of understanding hydraulic jack work immediately to a certain extent,, when hydraulic jack is manipulated, it is unstable that the mechanical type pointer gauge exists demonstration usually, and this closes down for using field boundary at some, will cause actual job is lost the ability of control fully of having got, so, will have a direct impact practical operation effect in the operation process.
Summary of the invention:
The purpose of this utility model is that a kind of improved hydraulic jack load numeric display unit will be provided, and it not only can demonstrate current load value with digital form effectively intuitively, is beneficial to the proper operation in the process, and, simple in structure, easy to use.
In order to realize that above-mentioned purpose the utility model proposes following design plan: hydraulic jack load numeric display unit of the present utility model comprises a base, the large tank that is provided with big piston on the base, the small oil tank that has valve piston, the fuel tank that large tank is outer, the high pressure oil pipeline that has check valve between small oil tank one end and the large tank, oil pipe line that has check valve between the fuel tank and the small oil tank other end and unloader valve etc., also be provided with the high pressure oil pipeline that an end is communicated with large tank and other end end is provided with a pressure transducer in the described base, the mouth of described pressure transducer forms by the cable and the input end of numeric display main frame on being installed in base and is electrically connected.
Because the utility model has improved existing hydraulic jack, and be connected with a pressure transducer by described high pressure oil pipeline at the large tank place, the mouth of pressure transducer forms by cable with the input end of numeric display main frame on being installed in base and is electrically connected, in operating process, pressure transducer is monitored the pressure of hydraulic oil at any time, with pressure conversion is that electric signal is transferred to the numeric display host process, and on telltale, demonstrate current load value intuitively with digital form, help the in good time control in the operation process.
Description of drawings:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the scheme drawing of hydraulic jack load numeric display unit of the present utility model.
Fig. 2 is the partial schematic sectional view of hydraulic jack load numeric display unit of the present utility model.
The specific embodiment:
Embodiment to hydraulic jack load numeric display unit of the present utility model describes in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, the hydraulic jack load numeric display unit of this utility model by described base 1, the described large tank 3 that is provided with big piston 2, describedly be provided with the small oil tank 5 of valve piston 4, described large tank 3 outer fuel tank 6, described unloader valve 11 and described numeric display main frames 15 are formed.
Described large tank 3, described small oil tank 5, described large tank 3 outer fuel tank 6, described unloader valve 11 and described numeric display main frames 15 all are arranged on the described base 1.
Be connected with a high pressure oil pipeline 8 between one end of described small oil tank 5 and the described large tank 3, one end of described high pressure oil pipeline 8 is equipped with a check valve 7, also be communicated with between the other end of described small oil tank 5 and the described fuel tank 6 by a described oil pipe line 10, one end of described oil pipe line 10 is equipped with a check valve 9, described unloader valve 11 is configured between described large tank 3 and the described fuel tank 6, also be provided with the high pressure oil pipeline 13 that an end is communicated with large tank 3 in the described base 1, the other end end of described high pressure oil pipeline 13 is equiped with a pressure transducer 12, and the mouth of the pressure transducer 12 on the other end end of the described input end that is placed in the numeric display main frame 15 on the base 1 and described high pressure oil pipeline 13 forms by cable 14 and is electrically connected.
The use of hydraulic jack load numeric display unit of the present utility model, when the valve piston 4 in the described small oil tank 5 moves downward, hydraulic oil in the described large tank 3 transmits pressure, promote described big piston 2 jacking load, simultaneously, the pressure that acts on the described pressure transducer 12 is converted to electric signal by pressure transducer 12, and be passed to the input end of described numeric display main frame 15 by cable 14 by the mouth of described pressure transducer 12, and show with digital form, operating personal can effectively be supportted hold process control.
