Description
Technical field
The present invention relates to a kind of tractor hydraulic lifting test platform, specifically the vertical self-checking device of a kind of tractor hydraulic lifting test platform.
Background technology
Tractor Hydraulic Lift Capacity test is Tractor Products to be carried out to numerous performances detect basic, a necessary test in test.To the main loading method of the test of Tractor Hydraulic Lift Capacity, there is pouring weight to load and oil cylinder loading both at home and abroad.Pouring weight loads and shows as all the time vertical power, meet standard-required, but load can not change continuously, not accurate enough during test feed pull maximum, this load mode is simple but inconvenient, needs a large amount of pouring weights and counterweight, and can only carry out lifting force test and quiet settling test.Oil cylinder loads more convenient, by adjusting the set pressure value of surplus valve, realizes the continuous variation of load, but will make to load cylinder, cannot remain perpendicular to the ground in lifting process, variant with the operating condition of test of standard-required, has loading error.
Summary of the invention
The object of this invention is to provide the vertical self-checking device of a kind of tractor hydraulic lifting test platform, it can make load cylinder in lifting process, remain perpendicular to the ground, guarantee that in lifting process, loading force is consistent with simulated farm implements gravity direction, eliminate loading error.
The present invention for achieving the above object, be achieved through the following technical solutions: comprise base, the first side plate and the second side plate are installed on base, the first upper rail and the first lower guideway are installed on the first side plate, the second upper rail and the second lower guideway are installed on the second side plate, between the first upper rail and the first lower guideway, the first row travelling wheel is installed, between the second upper rail and the second lower guideway, the second road wheel is installed, the first row travelling wheel is all connected with dolly with the second road wheel, slot is offered in dolly bottom surface, inserted sheet is installed in slot, inserted sheet is connected with screw, screw is arranged on leading screw, leading screw is arranged on base, leading screw one end is connected with the output shaft of servomotor, even hinge block is installed at dolly top, even hinge block and load cylinder are hinged, load cylinder top mounted angle sensor, obliquity sensor is all connected with controller by wire with servomotor.Between the first side plate and the second side plate one end, baffle plate is installed, stay-supported type displacement sensor is installed on baffle plate, the cable end of stay-supported type displacement sensor is connected with dolly.Handwheel is installed in leading screw end.Air level is installed on load cylinder.
The invention has the advantages that: can make load cylinder in lifting process, remain perpendicular to the ground, guarantee that in lifting process, loading force is consistent with simulated farm implements gravity direction, eliminate loading error, load cylinder when work to leading screw without pressure, long service life, the angle of load cylinder can manual adjustments etc.
