[0024] Refer to Figure 1 , Figure 2 and Figure 3, an embodiment provided by the present utility model: a heavy-duty RGV electric flat car, including a trolley box main body 1, a base 2 is fixedly connected to the top of the trolley box main body 1, a lifting platform 4 is slidably connected inside the base 2, sliding grooves 12 are respectively opened at the inner bottom of the trolley box main body 1, sliders 13 are respectively slidably connected inside the sliding grooves 12, the top of the left slider 13 is respectively rotatably connected with a first scissor arm 14, the top of the right slider 13 is respectively rotatably connected with a second scissor arm 15, the top ends of the first scissor arms 14 are respectively rotatably connected inside a rolling box 16, the top ends of the second scissor arms 15 are respectively rotatably connected inside the rolling box 16, the rolling boxes 16 are respectively fixedly connected to the bottom of the lifting platform 4, a first hydraulic telescopic rod 17 is fixedly connected to the inner bottom of the trolley box main body 1, the output end of the first hydraulic telescopic rod 17 is fixedly connected to the bottom of the lifting platform 4, second hydraulic telescopic rods 18 are respectively fixedly connected to the inner bottom of the trolley box main body 1, the output ends of the second hydraulic telescopic rods 18 are respectively fixedly connected to the bottom of the lifting platform 4, anti-collision components are respectively fixedly connected to both sides of the trolley box main body 1, the anti-collision components include sliding cylinders 8, the sliding cylinders 8 are respectively fixedly connected to the outer sides of both sides of the trolley box main body 1, buffer springs 9 are respectively fixedly connected inside the sliding cylinders 8, one end of each buffer spring 9 is respectively fixedly connected to a sliding rod 10, the sliding rods 10 are respectively slidably connected inside the sliding cylinders 8, and one end of each sliding rod 10 is respectively fixedly connected to a rubber pad 11.
[0025] By driving four second hydraulic telescopic rods 18 and one first hydraulic telescopic rod 17 to drive the lifting platform 4 to rise, when the lifting platform 4 rises, the first scissor arms 14 and the second scissor arms 15 move closer to the middle. The two groups of scissor arms move inside the sliding grooves 12 through the sliders 13, and the top ends of the two groups of scissor arms slide inside the rolling boxes 16 through the rollers, so as to achieve the effect of moving closer to the middle. When a collision occurs, the rubber pad 11 squeezes the sliding rod 10, the sliding rod 10 squeezes the buffer spring 9, and the buffer spring 9 absorbs the force generated by the collision, so as to achieve the function of buffer protection.
[0026] Refer to Figure 4 , installation grooves 26 are respectively opened at the top of the lifting platform 4, telescopic rods 19 are respectively fixedly connected inside the installation grooves 26, the top ends of the telescopic rods 19 are respectively fixedly connected with shock-absorbing mounting plates 20, shock-absorbing mounting plates 20 are respectively fixedly connected to the top of the shock-absorbing mounting plates 20, movable sleeves 21 are respectively fixedly connected to the inner bottom of the movable sleeves 21, first shock-absorbing springs 22 are respectively fixedly connected to the top ends of the first shock-absorbing springs 22, connecting plates 23 are respectively fixedly connected to the top ends of the first shock-absorbing springs 22, and the connecting plates 23 are respectively slidably connected inside the movable sleeves 21.
[0027] The first shock-absorbing spring 22 is used for shock absorption and buffering. The connecting plate 23 is used to connect the shock-absorbing seat 25. The shock-absorbing seat 25 drives the connecting plate 23 to slide inside the movable sleeve 21. The connecting plate 23 squeezes the first shock-absorbing spring 22, thereby driving the movable sleeve 21 and the shock-absorbing mounting plate 20 to squeeze the telescopic rod 19, achieving the effect of shock absorption and buffering. The installation groove 26 is used to install the telescopic rod 19.
[0028] Refer to Figure 1 , Figure 2 and Figure 4 , the top of the connecting plate 23 is fixedly connected with a second shock-absorbing spring 24. The second shock-absorbing springs 24 are fixedly connected to the inner top of the movable sleeve 21. The top of the connecting plate 23 is fixedly connected with a shock-absorbing seat 25. The bottom ends of the shock-absorbing seats 25 are slidably connected inside the movable sleeve 21. The top of the shock-absorbing seat 25 is fixedly connected to the bottom of the bearing platform 5. A door 7 is provided on the front side of the tram car body 1. Cameras 6 are fixedly connected to the outside of the base 2. Movable wheels 3 are rotatably connected to the bottom of the tram car body 1.
[0029] The second shock-absorbing spring 24 is used for shock absorption, buffering and resetting. When the loaded goods are unloaded, the elastic force of the second shock-absorbing spring 24 drives the connecting plate 23 to move. The connecting plate 23 drives the shock-absorbing seat 25 and the bearing platform 5 to move, realizing resetting. The door 7 is used for maintenance. The camera 6 is used for visual navigation. Through visual navigation, it can accurately identify and track a predetermined path and avoid obstacles. The movable wheels 3 are used for moving and transporting.
[0030] Working principle: When using this equipment, when the goods to be transported are placed on the bearing platform 5, the bearing platform 5 is compressed by the goods. The bearing platform 5 squeezes the shock-absorbing seat 25. The shock-absorbing seat 25 drives the connecting plate 23 to squeeze the first shock-absorbing spring 22, thereby driving the movable sleeve 21 and the shock-absorbing mounting plate 20 to squeeze the telescopic rod 19, effectively improving the overall buffering effect and making the movement more stable when overloaded. When it is necessary to raise the bearing platform 5, the four second hydraulic telescopic rods 18 and the first hydraulic telescopic rod 17 are driven to rise, thereby driving the lifting platform 4 to rise. When the lifting platform 4 rises, the first scissor arm 14 and the second scissor arm 15 move closer to the middle, realizing the rise of the lifting platform 4, thereby improving the stability of the entire base 2 and making the lifting process more stable and reliable. The lifting platform 4 thus raises the entire bearing platform 5.
