DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 , a new type of car lifting device in this embodiment includes a lifting frame 1, and a lifting mechanism is arranged inside the lifting frame 1;

[0023] The lifting mechanism includes a cylinder 2 fixedly connected to the left and right sides of the lifting frame 1, the output shaft of the cylinder 2 is fixedly connected to the lifting platform 3, the left and right sides of the lifting frame 1 are provided with limited openings 4, the top of the lifting platform 3 is fixedly connected to a fixed frame 5, the inner side of the fixed frame 5 is rotatably connected to a lifting roller 6, the top of the lifting frame 1 is fixedly connected to a frame 7, the front of the frame 7 is fixedly installed with a driving motor 8, the output shaft of the lifting frame 1 is fixedly connected to a driving shaft 9, the outer surface of the driving shaft 9 is installed with a winding drum 10, and the outer surface of the winding drum 10 is wrapped and fixedly connected with a steel cable 11. When in use, the cylinder 2 can drive the lifting platform 3 to rise, and at the same time, the driving motor 8 can drive the winding drum 10 to rotate through the driving shaft 9, so that the steel cable 11 continuously pulls up the lifting platform 3 through the lifting roller 6, so that the two cooperate with each other and reduce the pressure on each other, thereby lifting the lifting platform 3 to a specified height relatively quickly and smoothly.

[0024] Compared with the currently available lifting devices, it adopts the method of using the cylinder 2 and the steel cable 11 to cooperate with each other to lift the lifting platform 3. The lifting speed is faster and is less affected by changes in external ambient temperature, which improves the efficiency of loading and unloading goods and is more conducive to outdoor use.

[0025] Among them, a positioning frame 12 is fixedly connected to the inner side of the lifting frame 1, and a guide wheel 13 is rotatably connected to the inner side of the positioning frame 12 due to the sliding of the steel cable 11. By setting the positioning frame 12 and the guide wheel 13, when the steel cable 11 continuously pulls up the lifting platform 3, the guide wheel 13 can guide the steel cable 11 and limit it to the inside, thereby avoiding the steel cable 11 from deviating or falling off.

[0026] It should be noted that the limit opening 4 is slidably connected to the lifting platform 3, the lower end of the steel cable 11 is fixedly connected to the outer surface of the lifting roller 6, there are two drive motors 8, and the two drive motors 8 have the same speed and opposite rotation directions.

[0027] Among them, a ramp plate 14 is fixedly connected to the front of the lifting frame 1, and the ramp plate 14 is trapezoidal. Wheel positioning grooves 15 are opened around the top of the lifting platform 3. The inner side and edge of the wheel positioning groove 15 have a smooth transition. By setting the ramp plate 14 and the wheel positioning groove 15, the effect of facilitating the movement of the car and limiting the wheel is achieved.

[0028] In addition, a base plate 16 is fixedly connected to the bottom of the lifting frame 1, a threaded sleeve 17 is fixedly connected to the top of the base plate 16, an insert rod 18 is connected to the internal thread of the threaded sleeve 17, a turntable 19 is fixedly connected to the top of the insert rod 18, and a plug hole 20 is provided around the top of the base plate 16. Through the cooperation of the threaded sleeve 17, the insert rod 18, the turntable 19 and the plug hole 20, the staff only needs to rotate the turntable 19 clockwise to make the insert rod 18 rotate synchronously and move vertically downward, so that after positioning through the plug hole 20, the bottom end of the insert rod 18 is finally inserted into the ground, thereby enhancing the stability of the fixation of the base plate 16 and reducing the probability of large vibrations.

[0029] The working principle of the above embodiment is:

[0030] When in use, the staff first needs to drive the car to the top of the lifting platform 3 through the ramp plate 14, and limit the wheels of the car through the wheel positioning groove 15 to avoid position deviation. After the movement is completed, the lifting platform 3 and the drive motor 8 are remotely started through the controller, wherein the cylinder 2 can drive the lifting platform 3 to rise. At the same time, the drive motor 8 located on the left side of the lifting frame 1 can drive the drive shaft 9 to rotate clockwise, and the drive motor 8 located on the right side of the lifting frame 1 can drive the drive shaft 9 to rotate counterclockwise, thereby finally driving the winding drum 10 to rotate and continuously winding the steel cable 11, so that the steel cable 11 can pass through The lifting roller 6 continuously pulls up the lifting platform 3, so that the two cooperate with each other and reduce the pressure on each other, and then the lifting platform 3 is lifted to the specified height relatively quickly and smoothly. When the car moves to the specified height, the staff can drive the car from the top of the lifting platform 3 to the parking space of the shelf. When the car is parked, open another car on the shelf and move it to the top of the lifting platform 3. Then, reset the cylinder 2 and release the steel cable 11 again, so that the car is lowered to the specified height and transferred to the warehouse. Afterwards, the staff only needs to repeat the above process to unload and load the cars in batches.

[0031] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role, and the existing public power connection technology is not described in detail in the text.
