Be provided with lifting rope in the described guiding device, the lifting rope lower end connects drops hammer, and the bottom of dropping hammer cooperates with air spring, and air spring cooperates with load plate; The simultaneous displacement sensor cooperates with lifting rope.
Described air circuit breaker device is the two-bit triplet electromagnetic valve.
Be equipped with sound absorber on described cylinder and the two-bit triplet electromagnetic valve.
Described control device is a single-chip microcomputer, and it is connected with computer.
Described cylinder is connected with air pump through two-bit triplet electromagnetic valve, choke valve, pressurizer tank.
The utility model is made up of three parts, automatic control system, pneumatic system, loading system.Automatic control system is made up of single-chip microcomputer, displacement transducer and computer.In single-chip microcomputer, write control height of the fall and the program of intermittent time by computer.When beginning to move under the instruction of cylinder at single-chip microcomputer, be connected the sling height that the displacement transducer record on the air cylinder connecting rod drops hammer, and constantly data are fed back to single-chip microcomputer, thus the switch of control two-bit triplet electromagnetic valve, further control cylinder is by pressing the system acting that is provided with in advance.The sling height of dropping hammer, intermittent time and loading number of times etc. are presented on the computer screen in real time.
Pneumatic system is made up of cylinder, two-bit triplet electromagnetic valve, sound absorber, pressurizer tank, air pump etc.The circulation of air is by the switch control of electromagnetic valve in the cylinder, air pump compressed air enters cylinder, thereby promotes the certain height of dropping hammer, two-bit triplet electromagnetic valve transposition then, air is extruded in the cylinder, drops hammer to do the movement of falling object and hit air spring on the load plate.Sound absorber is all passed through in the discharging of air simultaneously, thereby reduces noise.
