The lifting mechanism 5 comprises a double-axis motor 51 fixedly installed at the upper end of the cover plate 3, and rotating rods 5 are fixedly arranged at both ends of the double-axis motor 51. 2, a support plate 53 is fixedly connected to the upper end of the cover plate 3 near the two groups of rotating rods 52, and a winding wheel 54 is fixedly provided at the opposite ends of the two groups of rotating rods 52. An upper pulley block 55 is fixedly installed near the two side edges of the lower end of the cover plate 3, and a fixing sleeve 56 is fixed to the upper pulley block 55. The two ends of the lifting platform 4 are fixedly connected to connecting plates 57, and a lower pulley block 58 is fixedly provided on the upper end of the connecting plate 57. A steel rope 59 is sleeved between the upper pulley block 55 and the lower pulley block 58.

[0022] In this embodiment, the support plate 53 is movably sleeved on the outer side of the rotating rod 52, the positions of the upper pulley group 55 and the lower pulley group 58 correspond, and the steel rope 59 is movably wound around the inner rollers of the upper pulley group 55 and the lower pulley group 58. One end of the steel rope 59 is fixedly connected to the fixed sleeve 56, and the other end of the steel rope 59 is movably passed through the cover plate 3 and fixedly connected to the winding wheel 54.

[0023] Specifically, by starting the dual-axis motor 51, the rotating rods 52 and the winding wheels 54 on both sides are driven to rotate, so that one end of the fixed steel rope 59 can be wound or released, and the lifting platform 4 connected to the lower side can be lifted or lowered. The design of the steel rope 59 being wound around the upper pulley group 55 and the lower pulley group 58 and the labor-saving principle of the pulley group can greatly reduce the pressure of the dual-axis motor 51 pulling the lifting platform 4 during operation, thereby improving the protection and life of the driving components.

[0024] In this embodiment, the limiting mechanism 6 includes a ramp plate 61 movably connected to the front side of the lifting platform 4, two groups of grooves 62 are provided on the inner side of the ramp plate 61, and the rear inner wall of the groove 62 and the rear end of the ramp plate 61 are fixedly connected with a connecting shaft 63, and a hydraulic cylinder 64 is movably connected between the two groups of connecting shafts 63. K-shaped grooves 65 are provided at positions corresponding to the two groups of grooves 62 on the inside of one side of the lifting platform 4, and an obtuse-angled limiting plate 66 is movably arranged inside the K-shaped groove 65.

The upper side of the ramp plate 61 is connected to the lifting platform 4, and the telescopic rod of the hydraulic cylinder 64 is connected to the connecting shaft 63 on the ramp plate 61. The obtuse-angled limiting plate 66 is adapted to the K-shaped groove 65, and the lower side of the obtuse-angled limiting plate 66 is located between the two groups of driving blocks 67.

[0025] Specifically, the lifting platform 4 is lowered, and the hydraulic cylinder 64 is started at the same time to push the ramp plate 61 to rotate along the upper side. When the lifting platform 4 is placed on the upper end of the bottom plate 1, the ramp plate 61 is tilted and opened to facilitate the car to drive onto the upper end of the lifting platform 4. At the same time, the driving block 67 on the rear side will push the lower side of the obtuse angle limit plate 66 and rotate it to the K-shaped groove 65. When the lifting platform 4 rises, the ramp plate 61 is pulled back to drive the driving block 67 on the front side to push the lower side of the obtuse angle limit plate 66, so that the upper sides of the two groups of obtuse angle limit plates 66 are erected at the front and rear sides of the wheels to prevent slipping, movement, etc.

The steel rope 59 is wound around the upper pulley block 55 and the lower pulley block 58, and the pulley block labor-saving principle is used to greatly reduce the pressure of the dual-axis motor 51 pulling the lifting platform 4 during operation, thereby improving the protection and life of the driving components. Then, the lifting platform 4 is lowered, and at the same time, The hydraulic cylinder 64 is started to push the ramp plate 61 to rotate along the upper side. When the lifting platform 4 is placed on the upper end of the bottom plate 1, the ramp plate 61 is tilted and opened to facilitate the car to drive onto the upper end of the lifting platform 4. At the same time, the driving block 67 on the rear side will push the lower side of the obtuse angle limit plate 66 and rotate it to the K-shaped groove 65. When the lifting platform 4 rises, the ramp plate 61 is pulled back to drive the driving block 67 on the front side to push the lower side of the obtuse angle limit plate 66, so that the upper sides of the two groups of obtuse angle limit plates 66 are erected at the front and rear sides of the wheels to prevent slipping, movement, etc.
