The utility model aims to overcome the defects of an existing hydraulic testing machine and an existing hydraulic press machine, and provides a hydraulic testing machine of a multi-hydraulic cylinder combined jacking device. The hydraulic testing machine consists of a bearing cap, a steel structure framework, a bearing platform, a multi-hydraulic cylinder combined jacking device, a hydraulic station and a detection control system. The hydraulic testing machine is characterized in that the large-sized steel structure framework is spliced at an installation site, and is convenient to transport; the number of the hydraulic cylinders can be two or any figure greater than two as long as the hydraulic cylinders are uniformly and symmetrically arranged, and flexibility is high; an upper part of the multi-hydraulic cylinder combined jacking device is equipped with a testing platform; during a test, the hydraulic station supplies oil to working hydraulic cylinders simultaneously, the detection control system controls the ascending velocity of the bearing platform, the operation is convenient, and control is easily realized; and when required test pressure is relatively small, only a few of the multiple hydraulic cylinders needs to be started symmetrically, the test pressure can be large or small, and the test range is wide.
Description
Technical field
The utility model relates to a kind of multi-hydraulic-cylinder combination hydraulic testing equipment.
Background technology
Now, portion's productization of building member, standardization and batch production production become the architectural development direction of sustainable development, and the required testing equipment of check in the building portion product production run becomes demand accordingly.Wherein, the building column of steel construction need be done pressure test usually, the column of a building need carry the pressure load of hundreds of tons and even thousands of tons of usually, and the height of uprights product is usually at 3～6 meters, therefore need the testing machine of large-tonnage pressure (reaching thousands of tons of and even up to ten thousand tons of pressure) to carry out pressure test, this testing machine is fit to the test specimen height and wants to satisfy building column requirement for height.
Current existing various hydraulic dynamometers all have certain limitation, mainly contain following characteristics: be applicable to that 1. tested member length dimension is generally below 1m; 2. test general pressure generally below hundreds of kN.Existing various hydraulic dynamometers are not suitable for building the pressure test requirement of column on the market.
Current existing various hydraulic press all are that the uncomfortable cooperation experimental use of its structure also can't satisfy the testing requirements to the building column by the design of the special purpose of its equipment.
If adopt single hydraulic cylinder form in the large hydraulic testing machine, then single hydraulic cylinder need produce the pressure of thousands of tons of and even up to ten thousand tons, can cause like this: 1. the design of hydraulic cylinder and making requires all very high; 2. single hydraulic cylinder weight is huge, and difficulty is installed; 3. if problem, the solution cycle is long, the cost height.
The utility model content
The purpose of this utility model provides a kind of large hydraulic testing machine of simple in structure, multi-hydraulic-cylinder combined type jacking apparatus that working stability is reliable, easy to maintenance.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: multi-hydraulic-cylinder combined large hydraulic dynamometer is made up of pressure-bearing cap, steel structure frame, pressure-bearing platform, multi-hydraulic-cylinder combination jacking apparatus, Hydraulic Station and detection control system.
Steel structure frame by 2 columns, back timber and grade beams totally 4 form, be convenient to like this transportation, splice again to the erecting stage.
Multi-hydraulic-cylinder is meant that the number of the hydraulic cylinder in the multi-hydraulic-cylinder combination jacking apparatus can be 2 and above any numeral, and these hydraulic cylinders are arranged symmetrically, make the jacking of multi-hydraulic-cylinder combination jacking apparatus make a concerted effort to be centered close to by the test specimen axial location.
A pressure-bearing platform is done on multi-hydraulic-cylinder combination jacking apparatus top, and this pressure-bearing platform has enough rigidity.
Space between pressure-bearing platform and the pressure-bearing cap is that tested member is laid the space.Height H between original state pressure-bearing platform and the pressure-bearing cap is that tested member height adds desired height surplus when laying member, and this altitude margin is less than hydraulic cylinder jacking stroke.
During testing operation, Hydraulic Station is the working hydraulic pressure oil supply cylinder in multi-hydraulic-cylinder combination jacking apparatus simultaneously, by the control system control pressure-bearing platform jacking speed that makes progress.
During concrete test, when required test pressure is enough big, make multi-hydraulic-cylinder make up all hydraulic cylinder in the jacking apparatus all work (all hydraulic cylinder all is the working fluid cylinder pressure); When required test pressure relatively hour, only need symmetry to open part hydraulic cylinder (this part hydraulic cylinder is the working fluid cylinder pressure) in the multi-hydraulic-cylinder combination jacking apparatus, other hydraulic cylinder is closed.
Description of drawings
Accompanying drawing is the multi-hydraulic-cylinder combined large hydraulic dynamometer structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Multi-hydraulic-cylinder combined large hydraulic dynamometer is made up of pressure-bearing cap 1, steel structure frame 2, pressure-bearing platform 3, multi-hydraulic-cylinder combination jacking apparatus 4, Hydraulic Station 5 and detection control system 6.
During the testing machine assembling, at first 2 columns, back timber and grade beam assembly unit are welded into steel structure frame 2; Then pressure-bearing cap 1 is fixed on the back timber of steel structure frame 2; The a plurality of hydraulic cylinders that again multi-hydraulic-cylinder made up in the jacking apparatus 4 are arranged symmetrically on the grade beam of steel structure frame 2; Pressure-bearing platform 3 is put on the multi-hydraulic-cylinder combination jacking apparatus 4; Pressure-bearing platform center and pressure-bearing cap center are on a pedal line.
Height H between original state pressure-bearing platform and the pressure-bearing cap is that tested member height adds desired height surplus when installing, and this altitude margin is less than hydraulic cylinder jacking stroke.
During testing operation, at first tested member is placed on location on the pressure-bearing platform 3, guarantees that tested member axis is consistent with the resultant direction of multi-hydraulic-cylinder combination jacking apparatus 4 jackings; Then,, determine working fluid cylinder pressure number, and set hydraulic cylinder jacking speed by control system according to required pressure size; Open the Hydraulic Station 5 a plurality of working hydraulic pressure oil supply cylinders in multi-hydraulic-cylinder combination jacking apparatus 4 simultaneously, detection control system 6 control pressure-bearing platforms 3 are pressed setting speed and are risen; Detect control system 6 and write down data such as the test pressure and the tested deformation of member simultaneously, finish until the test figure collection; The pressure-bearing platform is descended fast, take off tested member.
