Technical Field

[0001] The utility model relates to the technical field of automobile repair and maintenance equipment, in particular to a double-column automobile lifting device. Background Art

[0002] Two-post lift is a special mechanical lifting equipment commonly used in automobile repair and maintenance units. Two-post lift is the main type of lift and is widely used in the repair and maintenance of small cars such as sedans. There are two types of two-post lifts: symmetrical and asymmetrical. The four arms of the symmetrical lift are roughly equal in length, so that the center of the car (or center of mass) is in the middle of the column.

[0003] At present, the commonly used lifting equipment in the automobile maintenance industry includes a two-post lift, which is widely used due to its compact structure, beautiful appearance and easy operation. Traditional two-post lifts usually use a motor to drive a hydraulic pump to achieve lifting movement through a hydraulic system. However, these devices may have insufficient width between the columns in some cases, resulting in the inability to open the door after the car is lifted, causing inconvenience to maintenance personnel. Therefore, the traditional two-post lift still needs to be improved in terms of width between the columns, lifting stability and ease of operation. Based on this, a two-post car lifting device is proposed to solve the above problems. Utility Model Content

The turntable is fixed on the upper surface of the rotating shaft, and the supporting arm is fixed on the upper surface of the turntable.

[0016] By adopting this technical solution and utilizing the adjustable support arm design, the device can be adapted to different vehicle models and maintenance requirements, thereby improving the versatility and practicality of the device.

A driving handle is fixed to the upper surface of the threaded rod 3. Lighting lamps are fixed on the opposite sides of the two columns 1. The number of lighting lamps is not less than two and they are evenly distributed on the opposite sides of the two columns 1.

[0032] It should be noted that the stable base 2 is made of heavy steel and is added to the lower surface of the column 1 to increase the stability of the entire lifting device. The stable base 2 is fixedly connected to the column 1 by bolts to ensure that no shaking or tilting occurs during the lifting process.

[0033] See also Figure 2 In order to improve the stability and stability when the car is lifted, the stabilizing mechanism 4 in this embodiment includes a controller 41, a lifting platform 42, four hydraulic cylinders 43, four angle sensors 44 and two limit rods 45. The controller 41 is fixed on the left side of the left end column 1. The two columns 1 are provided with fixing grooves 46 on opposite sides. The four hydraulic cylinders 43 are respectively fixed on the front and rear sides of the inner top walls of the two columns 1. The piston rods of the four hydraulic cylinders 43 are fixed to the upper surface of the lifting platform 42. The car is driven into the lifting platform 42, and then the hydraulic cylinders 43 are started by the controller 41. The piston rods of the hydraulic cylinders 43 move upward, so that the lifting platform 42 moves upward. The angle sensor 44 is fixed on the upper surface of the lifting platform 42, and the limit rod 45 is fixed between the inner top wall and the inner bottom wall of the fixing groove 46.

[0034] In this embodiment, the limit rod 45 is slidably connected to the lifting platform 42, and the two ends of the lifting platform 42 slide on the outer surface of the limit rod 45 to limit the movement of the lifting platform 42. Four angle sensors 44 are located at the four corners of the lifting platform 42, and an anti-slip pad is fixed in the middle of the upper surface of the lifting platform 42, and the anti-slip pad is a rubber pad.

[0035] It should be noted that angle sensors 44 are respectively installed on the four corners of the lifting platform 42 for real-time monitoring of the position and status of the lifting platform 42. The angle sensors 44 are connected to the control system in the controller 41. When the lifting platform 42 is offset or unbalanced, the control system in the controller 41 can adjust the pressure of the hydraulic cylinder 43 in time to ensure the stability of the lifting platform 42.

[0036] See also Figures 3 to 4 In order to adapt to different vehicle models and maintenance requirements, the support mechanism 5 in this embodiment includes a drive motor 51, a rotating shaft 52, a turntable 53 and a support arm 54. The upper surface of the stable base 2 and the front and rear sides of the column 1 are provided with a receiving groove 55. The drive motor 51 is fixed in the inner cavity of the receiving groove 55. The rotating shaft 52 is rotatably connected to the upper surface of the stable base 2 through a bearing. The output shaft of the drive motor 51 passes through the receiving groove 55 and extends to the upper surface of the stable base 2 and is fixed to the rotating shaft 52. The turntable 53 is fixed on the upper surface of the rotating shaft 52. By starting the drive motor 51, the output shaft of the drive motor 51 rotates to drive the rotating shaft 52 to rotate, and the rotation of the rotating shaft 52 drives the turntable 53 to rotate. The support arm 54 is fixed on the upper surface of the turntable 53. The rotation of the turntable 53 drives the rotation of the support arm 54. Then, the support arm 54 can be controlled by the control system to be adjusted so that the end of the support arm 54 is located at the bottom of the car for support.

[0037] In this embodiment, rollers are rotatably installed at both ends of the lower surface of the turntable 53, and circular grooves are opened on the upper surface of the stable base 2 and on the front and rear sides of the column 1. The rollers rotate in the inner cavity of the circular grooves, and a rubber pad is fixed at the end of the support arm 54 to protect the car body from damage.

[0038] The working principle of the above embodiment is:

[0039] (1) A stable base 2 is added to the lower surface of the column 1 to increase the stability of the entire lifting device. The stable base 2 is fixedly connected to the column 1 by bolts to ensure that there is no shaking or tilting during the lifting process. When lifting a car, the car is first driven into the lifting platform 42, and then the hydraulic cylinder 43 is started by the controller 41. The piston rod of the hydraulic cylinder 43 moves upward, causing the lifting platform 42 to move upward. At this time, the two ends of the lifting platform 42 slide on the outer surface of the limit rod 45 to limit the movement of the lifting platform 42. Angle sensors 44 are respectively installed at the four corners of the lifting platform 42 for real-time monitoring of the position and state of the lifting platform 42. The angle sensors 44 are connected to the control system in the controller 41. When the lifting platform 42 is offset or unbalanced, the control system in the controller 41 can adjust the pressure of the hydraulic cylinder 43 in time to ensure the stability of the lifting platform 42.

[0040] (2) In order to improve the stability of the support of the lifting platform 42, the driving motor 51 can be started. The output shaft of the driving motor 51 rotates to drive the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 drives the turntable 53 to rotate. The rotation of the turntable 53 causes the two rollers fixed on its lower surface to rotate in the inner cavity of the circular groove, which can limit the rotation of the turntable 53. The rotation of the turntable 53 drives the rotation of the support arm 54, and then the support arm 54 can be controlled by the control system to be adjusted, so that the rubber pad fixed at the end of the support arm 54 is located at the bottom of the car for support and to protect the car body from damage.
