Description
Technical field
The present invention relates to a kind of tractor hydraulic lifting test platform, the vertical self-checking device of specifically a kind of tractor hydraulic lifting test platform.
Background technology
The test of tractor hydraulic load-carrying capacity is the tractor product to be carried out numerous performances detect basic, a necessary test in the test.There is pouring weight to load and the oil cylinder loading to the main loading method of the test of tractor hydraulic load-carrying capacity both at home and abroad.Pouring weight loads and shows as vertical power all the time, the conformance with standard requirement, but load can not change continuously; Not accurate enough during the 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, realizes the continuous variation of load through the set pressure value of adjusting surplus valve, but it is perpendicular to the ground that the loading cylinder can't be remained in lifting process, and is variant with the operating condition of test of standard-required, has loading error.
Summary of the invention
The purpose of this invention is to provide the vertical self-checking device of a kind of tractor hydraulic lifting test platform; It is perpendicular to the ground that it can make load cylinder in lifting process, remain; Guarantee that loading force is consistent with the farm implements gravity direction of being simulated in the lifting process, eliminate loading error.
The present invention realizes through following technical scheme for realizing above-mentioned purpose: comprise base, first side plate and second side plate are installed on the base; First upper rail and first lower guideway are installed on first side plate, second upper rail and second lower guideway are installed on second side plate, first road wheel is installed between first upper rail and first lower guideway; Second road wheel is installed between second upper rail and second lower guideway, and first road wheel all is connected with dolly with second road wheel, and slot is offered in the dolly bottom surface; Inserted sheet is installed in the slot, and inserted sheet is connected with screw, and screw is installed on the leading screw; Leading screw is installed on the base, and leading screw one end is connected with the output shaft of servomotor, and even hinge block is installed at the dolly top; Even hinge block and load cylinder are hinged, load cylinder top mounted angle sensor, and obliquity sensor all is connected with controller through lead with servomotor.Between first side plate and second side plate, one end baffle plate is installed, the stay-supported displacement transducer is installed on the baffle plate, the cable end of stay-supported displacement transducer is connected with dolly.Handwheel is installed in the leading screw end.Air level is installed on the load cylinder.
The invention has the advantages that: it is perpendicular to the ground that load cylinder is remained in lifting process; Guarantee that loading force is consistent with the farm implements gravity direction of being simulated in the lifting process; Eliminate loading error; During load cylinder work leading screw there is not pressure, long service life, but the angle manual adjustments of load cylinder etc.
