[0024] Reference Figures 1-5 A training simulator for excavation operation, comprising a seat 1, a control rod 4, a rocker 5, the rocker 5 being arranged on both sides of the seat 1, an upper base 2 being arranged below the seat 1, the control rod 4 being arranged in front of the seat 1, a display screen 6 being arranged in front of the control rod 4, the seat 1, the display screen 6 and the control rod 4 all being mounted on the upper base 2.

[0025] The bottom of the upper base 2 is further provided with a lower base 3, a linkage mechanism being arranged between the upper base 2 and the lower base 3, the linkage mechanism comprising four support shafts 8, the lower base 3 being provided with a circular sliding rail 10, the lower ends of the support shafts 8 being slidably mounted on the sliding rail 10 through connecting blocks 9, the bottom of the upper base 2 being provided with a sliding groove 7 used in cooperation with the support shafts 8, the upper ends of the support shafts 8 being slid on the sliding groove 7.

[0026] A rotary motor (not shown) is installed inside the lower base 3. The drive end of the rotary motor is fixedly connected to a rotating shaft 12, which is movably connected to the bottom of the upper base 2.

[0027] A mounting block 15 is fixedly connected to the bottom of the upper base 2, and the upper end of the rotating shaft 12 is movably connected to the mounting block 15. During training, the upper base 2 will rotate and sway. The movable connection between the mounting block 15 and the rotating shaft 12 is adapted to the swaying process of the upper base 2.

[0028] Each groove 7 has a slider 16 slidably installed inside it. The upper end of the support shaft 8 is rotatably connected to the slider 16, and the lower end of the support shaft 8 is rotatably connected to the connecting block 9. The connecting block 9 is slidably installed on the slide rail 10. The four grooves 7 are evenly distributed around the bottom of the upper base 2. When the upper base 2 rotates, each support shaft 8 in the linkage mechanism moves accordingly. The connecting block 9 connected to the lower end of the support shaft 8 will slide on the slide rail 10 to adapt to the change in orientation. The upper end of the support shaft 8 is slidably installed through the slider 16 to adapt to the swinging process of the upper base 2.

[0029] A connecting plate 14 is fixedly connected between the two connecting blocks 9 facing each other. A rotating shaft 12 passes through the connecting plate 14. Hydraulic cylinders 11 are rotatably mounted on both ends of the connecting plate 14. A drive shaft 17 is fixedly connected to the drive end of each hydraulic cylinder 11. The two drive shafts 17 are movably connected to the middle sections of the two support shafts 8. By controlling the extension and retraction of the drive ends of the two hydraulic cylinders 11, the support shafts 8 are pushed or pulled to change their angle, thereby changing the overall angle of the upper base 2.

[0030] A protrusion 13 is provided at the middle section of the two support shafts 8 used to connect the drive shaft 17, and the drive shaft 17 is rotatably connected to the protrusion 13. The protrusion 13 connects the drive shaft 17 to one side of the support shaft 8.

[0031] The movable surface of the mounting block 15, which rotates relative to the rotating shaft 12, is on the same plane as the mounting surface of the support shaft 8, which is connected to the hydraulic cylinder 11.

[0032] Trainees sit in seat 1 for operation training, using the joysticks 5 on both sides and the control lever 4 in front to train for digging operations. The display screen 6 in front provides a virtual digging environment image. During operation, the upper base 2 can rotate relative to the lower base 3 according to the actual virtual environment and operation method, rotating at the horizontal angle. At the same time, the tilt angle of the upper base 2 will also change according to the specific environment to simulate the actual digging environment, that is, the state when the excavator is operating in a non-horizontal environment.

[0033] The rotary motor inside the lower base 3 can drive the rotating shaft 12 to rotate through the drive end. The rotating shaft 12 can drive the upper base 2 to rotate through the mounting block 15. When the upper base 2 rotates, the support shaft 8 connected to the bottom slide groove 7 can slide on the slide rail 10 through the connecting block 9 to adapt to the rotation of the upper base 2 on the plane.

[0034] When it is necessary to tilt the upper base 2, the two hydraulic cylinders 11 operate the connected support shaft 8 respectively. One end of the hydraulic cylinder 11 retracts, and the other end of the hydraulic cylinder 11 extends, thereby pulling the connected support shaft 8 and pushing one end of the support shaft 8 to move relative to the outside of the slide groove 7, which can lift one side of the upper base 2. Pulling one end of the support shaft 8 to move relative to the inside of the slide groove 7 can pull down the other side of the upper base 2. Thus, the two hydraulic cylinders 11 cooperate with each other to effectively tilt the upper base 2, so that the trainee will be in a tilted state to simulate a non-horizontal excavation environment.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
