The arm pin inserting and pulling mechanism of the suspension arm comprises a main base, an arm pin inserting and pulling assembly, a cylinder pin assembly and a self-locking mechanism, the arm pin inserting and pulling assembly, the cylinder pin assembly and the self-locking mechanism are mounted on the main base, and a first mounting hole, a second mounting hole and a third mounting hole are formed in the main base at intervals; the arm pin inserting and pulling assembly comprises an arm pin oil cylinder, an arm pin cylinder rod body and an arm pin, the cylinder pin assembly is inserted into the second mounting hole, the self-locking mechanism is arranged in the third mounting hole, and when the cylinder pin assembly moves, the other end of the self-locking mechanism can extend into the first mounting hole under the pushing of the cylinder pin assembly so as to stop the arm pin cylinder rod body from moving. The invention further provides a hydraulic control system. According to the direct type arm pin inse
