Embodiment
Fig. 1～Fig. 5 is the structural representation of a kind of drag-line durability experiment of the utility model device, comprise section bar stand 4, section bar stand 4 is provided with the stationary installation 1 of stay rope, also comprise the pneumatic means 5 being connected with drag-line, pneumatic means 5 comprises start cylinder and load cylinder 51, start cylinder is connected with the input end of drag-line, and load cylinder 51 is connected with the output terminal of drag-line; Also comprise the control system of controlling start cylinder, control system comprises PLC and three position five-way valve, and PLC is connected with three position five-way valve, and three position five-way valve is connected with start cylinder.
Hardware is mainly by the source of the gas that power is provided, the topworks as leading take pneumatic element and annex thereof, section bar and panel 3 are built section bar stand 4, all kinds of frock clamps and switch board 6 etc., software is by Mitsubishi PLC control, according to the requirement of industry standard QC/T29101-92, by stroke and the action of PLC control cylinder, thereby complete the detection of the anti-fatigue performance test of drag-line.
Crane: according to the length of drag-line exemplar, regulate the lifting of crane 2, then fixing, be mainly the fatigue durability test that meets all kinds of drag-lines, be separately convenient to install, dismantle.
Screw spiral: its effect is stay rope, adopt certain a bit or certain a bit of fixing, prevent that drag-line from swinging in durable process.The installation that screws bolt 12 is not to clamp drag-line pillar, but prevents that drag-line from swinging, and screws the diameter of 12 mouthfuls, bolt and the pillar diameter of drag-line is substantially the same, the drag-line pillar of putting into it is not squeezed, if step up pillar, may produce some impact to test findings, avoid as far as possible.Two ends screw bolt 12 when fixing, should install mouth to mouth, bolt opening all corresponding lifting support fix.
Pneumatic element: start cylinder and load cylinder 51 all increase guide piece 53, and on start cylinder, magnetic switch are installed.Pressure differential by two cylinders realizes run action.The power sensor 52 of monitoring use is arranged on load cylinder 51, because the load of drag-line is the output terminal at drag-line.The input end of drag-line is connected with start cylinder.
Control section and control gear: selecting the PLC of the FX1s-14MR of Mitsubishi is control program unit, SMC three position five-way valve is for controlling pneumatic unit.By writing the power on/off of internal processes control 3 position-5 way solenoid valve of PLC, the power on/off of solenoid valve realizes the break-make of air-flow, is realized the action back and forth of start cylinder by the break-make of air-flow.The requirement of other tests, such as cylinder action, number of times, frequency etc., can complete by PLC program.This PLC program is the core of whole testing table control.
If at run duration, the fracture of drag-line exemplar, post-rift drag-line will be not stressed, reaction is at load end, and being exactly load cylinder will be not stressed, and cylinder can not be realized and being moved back and forth by pressure differential, because load cylinder 51 does not move, now start cylinder will be responded to less than magnetic switch, and program can stop, not in operation.This has not only protected cylinder, and provides guarantee for test validity.
The guidance panel that switch board 6 is testing crew, comprises test run, stops, counting and reset and pilot lamp etc.Can carry out the drag-line long duration test of 4 stations simultaneously, according to testing requirements, can select to test accordingly station and test.
Experimentation is:
1), according to testing requirements, can select 1,000,000 times, 300,000 times, 100,000 inferior long duration test stations; Test cycle number of times can convert as requested, rewrites PLC program
2) according to the requirement of drag-line exemplar itself, by fixture, fix, install, after completing, open source of the gas, regulate pressure, drag-line movement travel, before test, give counter O reset;
3) on panel 3, open indicator light switch, green light, test run; When red, test stops.
4) after having tested, need to give PLC count resets, guarantee that next time, test was proceeded.
Adopt after such structure,
The control and adjusting of the durable stroke of 1.1 drag-line: the movement travel of every kind of drag-line is different, standard-required is not less than its actual impulse stroke for its movement travel, so on stand, to realize drag-line movement travel adjustable, control.Two magnetic switchs are installed on start cylinder, and the piston ring of magnetic switch induction start cylinder, regulates the distance of two magnetic switchs can control the movement travel of start cylinder, thereby guarantees the impulse stroke of drag-line.
The adjusting of 1.2 loads and monitoring: by the size of pressure valve adjustable pressure, thus the size of change load force, the monitoring of load force realizes by the power sensor 52 being arranged on drag-line.
1.3 guiding and adjustment: frock clamp guarantees, is mainly to guarantee that start cylinder and load cylinder 51 keep vertical motion and do not rotate in motion process, in order to avoid destroy exemplar.
1.4 automatic hold functions: PLC programmed control.When certain number of times is arrived in test run, test automatically out of service.
1.5 there is hold function when abnormal: magnetic switch signal passes to PLC, programmed control.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
