Final inspection test device and method for hydraulic lifting system of tractor

Abstract

The invention discloses a final inspection test device and method for a tractor hydraulic lifting system, belongs to the technical field of hydraulic lifting tests, and provides the following scheme that the final inspection test device comprises a test mechanism, and locking mechanisms are assembled on the two sides of the upper portion of the test mechanism; according to the invention, the lock catch assembly is clamped with the rear locking rod, and at the moment, the hydraulic arm of the tractor is lifted, so that an applied force lifts the load-bearing body upwards through the chain, and the upward lifting force of the hydraulic arm of the tractor can be tested, and then the upward lifting force of the hydraulic arm of the tractor can be tested through the clamping of the lock catch assembly with the front locking rod. The hydraulic arm of the tractor moves downwards to apply force downwards to the chain, the chain can lift the load bearing body again through power transmission, the requirement for testing the descending force of the hydraulic arm of the tractor is met, the upper load and the lower load of the hydraulic arm of the tractor are switched in the mode, the convenience of the testing operation is improved, and the testing efficiency is improved. Meanwhile, the comprehensiveness of the tractor hydraulic arm load test is met.
