[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, this invention illustrates an auxiliary vehicle lifting platform according to one embodiment of the present invention, comprising a rotary drive 1, an inner column 2 at the top of the rotary drive 1, a lifting cylinder 3 at the top of the inner column 2, a rear lifting platform 4 at the top of the lifting cylinder 3, and a support anti-fall assembly 8 at the bottom of the rear lifting platform 4. The support anti-fall assembly 8 includes a support rod 81, one end of which is fixedly connected to the side of the inner column 2, and the other end of which is fixedly connected to a motor 82. A threaded rod 83 is fixedly connected to the output shaft of the motor 82, and a threaded sleeve 84 is threadedly connected to the circumferential surface of the threaded rod 83. A limit rod 85 is fixedly connected to the top of the motor 82, and the end of the limit rod 85 away from the motor 82 passes through the bottom of the threaded sleeve 84. A support plate 86 is fixedly connected to the side of the threaded sleeve 84.

[0033] In some examples, the support plate 86 is located at the bottom of the rear lifting platform 4, and a protective pad 87 is fixedly connected to the top of the support plate 86. A platform flap 5 is provided on the top of the rear lifting platform 4. The protective pad 87 helps to protect the rear lifting platform 4 supported by the support plate 86 and prevents wear caused by the support.

[0034] There are two support rods 81, motor 82, threaded rod 83, threaded sleeve 84, and support plate 86, which are symmetrical to each other along the vertical central axis of the rear lifting platform 4. The two support plates 86 are conducive to providing stable support for the rear lifting platform 4.

[0035] The top of the platform flip plate 5 is equipped with a guardrail 6, the top of the rear lifting platform 4 is equipped with a grabbing operating platform 7, and the side of the rear lifting platform 4 is equipped with a front lifting platform 11. The design of the guardrail 6 helps to protect the workers who are operating the equipment.

[0036] The rear lifting platform 4 is located on the displacement trajectory of the support plate 86, the threaded rod 83 is located on the side of the rear lifting platform 4, and two protective pads 87 are provided. The provision of two protective pads 87 is beneficial to protect the bottom of the rear lifting platform 4 at the same time.

[0037] For example, such as Figures 1-5 As shown in this application, the front lifting platform 11 is fixed to the vehicle platform frame and is welded from high-strength steel. The platform is raised and lowered via a hydraulic cylinder. The lifting platform is equipped with a flap to expand the platform area. An eight-way electromagnetic reversing valve (drilling control valve) is installed on the platform, which can control the operation of the anchor bolt machine and the raising and lowering of the platform. The rear lifting platform 4 is fixed to the vehicle platform frame and is welded from high-strength steel. The platform is raised and lowered via a hydraulic cylinder. A rotary drive 1 is connected to the lower part of the platform frame to achieve platform rotation. The lifting platform is equipped with a flap to expand the platform area. A nine-way electromagnetic reversing valve (grip control valve) is installed on the platform, which can control the action of the grab arm and the raising, lowering, and rotation of the platform. The motor 82 is started, and when the motor 82 rotates, it drives the threaded rod 83 to rotate. The rotation of the threaded rod 83 drives the threaded sleeve 84 to move. The threaded sleeve 84 is controlled by a limit rod. The threaded sleeve 84 is restricted to move only up and down. This movement of the threaded sleeve 84 drives the support plate 86 to move up and down as well. The support plate 86 is located at the bottom of the lifting platform. When the lifting platform reaches the desired position, the support plate 86 can be moved to the bottom of the platform to provide additional support and prevent sudden falls. When the lifting platform reaches the desired position, the support plate 86 precisely provides additional support through the up-and-down movement of the threaded sleeve 84. This effectively prevents the risk of sudden falls during operation, ensuring operator safety. Through this structural design, the support plate 86 not only provides support at the bottom of the lifting platform but also effectively improves the overall stability of the platform. The stability of the lifting platform is enhanced during installation, maintenance, and daily use.
