Problems solved by technology
The lifting force is loaded by hoisting weights, although higher vertical accuracy can be obtained, but the hoisting of weights is not only complicated to operate, but also relatively dangerous; by installing servo motors or position adjustment cylinders, and directly adjusting servo motors or position adjustment cylinders Connected with the loading oil cylinder, the method of keeping the loading force vertical needs to install the test equipment below the ground, so as to facilitate the test of the lifting capacity of the tractor's lower rod at the lowest point

The invention discloses a tractor electric control hydraulic suspension system lifting capacity detection device and a detection method. The detection device comprises a test platform; a loading rackwhich is parallel to the test platform, and the loading rack is fixedly connected with the test platform; an agricultural implement frame, wherein one end of the agricultural implement frame is detachably connected to the tractor suspension system; a lifting device which is perpendicular to the loading rack; a position adjusting mechanism which is arranged on the loading rack; a first chain wheelwhich is rotatably mounted on the position adjusting mechanism; a second chain wheel which is rotatably mounted on the loading rack; a chain of which one end bypasses the first chain wheel and is connected to the agricultural implement frame, and the other end of the chain bypasses the second chain wheel and the lifting device and is connected to the loading rack; wherein the position adjusting mechanism can drive the first chain wheel to move, so that the chain is perpendicular to the loading rack; when the position of the agricultural implement frame is changed, the lifting device can drivethe chain to move, and the chain is tensioned.
Description
technical field [0001] The invention belongs to the technical field of lifting force testing of a tractor suspension mechanism, and in particular relates to a lifting capacity detection device and a detection method of a tractor electronically controlled hydraulic suspension system. Background technique [0002] Hydraulic and hydraulic suspension systems are important components of tractors, and their performance and reliability are directly related to the overall performance of the tractor. The hydraulic lifting mechanism of a tractor is an important working device connected to agricultural implements. The national standard has strict requirements on the hydraulic lifting force that the tractor can provide. Therefore, the measurement of the lifting force is one of the most important test items for the tractor. The national standard also has strict definitions for the measurement method of tractor hydraulic lifting force, requiring that the vertical lifting force must be mea...
