Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to an intelligent lifting device. Background Technology

[0002] A lifting device is a mechanical device that enables objects to move up and down, and it is widely used in various industrial, commercial, and everyday scenarios. It can be driven mechanically, hydraulically, pneumatically, or electrically to lift, lower, and position goods, equipment, or personnel. Lifting devices used in parking lots typically refer to mechanical devices used to lift and lower vehicles, using multi-level structures to increase the number of parking spaces.

[0003] Patent CN221119379U discloses a vertical lift garage with a vehicle shielding device. It includes a base, a connecting rod at the top of the base, and a shielding assembly at the top of the connecting rod for shielding the vertical lift garage. The shielding assembly includes a shielding plate, a pin at the connection point of the shielding plate, a clamping block on the outer wall of the pin, and a telescopic spring on the outer wall of the clamping block. A fixing bolt is located at the top of the connecting rod, and the outer wall of the fixing bolt slidably interlocks with the side of the shielding plate. A fixing nut is fitted onto the outer wall of the fixing bolt. When using this patent, a car is driven onto the support plate, and then a drive mechanism moves the support plate and the car upwards, creating a parking space between the support plate and the ground for a second vehicle to park. However, this existing patent still has some shortcomings in practical use. The support plate of the existing patent lacks any limiting mechanism. When some parts of the drive mechanism wear down due to prolonged use, the support plate is prone to tilting, causing the vehicle to slip off the support plate, resulting in vehicle damage and personal injury.

[0004] Therefore, there is a need to provide an intelligent lifting device with anti-rollover function. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, which have no limiting mechanism on the support plate, and whose support plate is prone to tilting when some parts of the drive mechanism are worn out due to long-term use, causing the vehicle to slip off the support plate and resulting in vehicle damage and personal injury, this utility model provides an intelligent lifting device with anti-slip function.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: an intelligent lifting device, comprising a base, inclined blocks, a lifting plate, a sliding frame 1, a limiting plate 1, a hinge frame, a limiting plate 2, a sliding frame 2, a dual-axis motor, and a bidirectional lead screw. Two inclined blocks are fixedly connected to the base, a dual-axis motor is installed inside the base, and two limiting plates 1 are fixedly connected inside the base. The output shaft of the dual-axis motor is connected to a bidirectional lead screw via a coupling. Two sliding frames 1 are threaded onto the bidirectional lead screw, and the two sliding frames 1 slide within adjacent limiting plates 1. Two sliding frames 1 located on the same bidirectional lead screw... The sliding frame is hinged to the base, and a lifting plate is slidably mounted on the base. Two limiting plates are fixedly connected to the lifting plate, and two sliding frames are slidably mounted inside the limiting plates. The two sliding frames located in the same limiting plate are hingedly connected to the adjacent hinge frame. The feature is that it also includes a positioning plate, an electric slider, and an electric slide rail. Four electric slide rails are slidably mounted on the lifting plate, and two electric sliders are installed on the electric slide rails. The electric sliders slide within the electric slide rails, and a positioning plate is fixedly connected to the electric sliders. The positioning plate slides on the lifting plate.

[0007] More preferably, it also includes a support plate, a rangefinder, a controller, and an alarm. The support plate is fixedly connected to the rear side of the base. The rangefinders are symmetrically installed on the top of the support plate. The controller is installed on the top of the support plate and is located between the two rangefinders. The alarm is installed at the rear of the base and is located in front of the controller.

[0008] More preferably, it also includes a mounting plate, a connecting plate, and an electric push rod. Mounting plates are fixedly connected to both sides of the lifting plate, and an electric push rod is installed on the inner side of the mounting plate. A connecting plate is installed on the telescopic rod of the electric push rod, and the connecting plate is fixedly connected to two electric slide rails on the same vertical line.

[0009] More preferably, it also includes a protective pad, with the protective pad embedded inside the card slot plate.

[0010] More preferably, it also includes reflectors, with reflectors embedded on both the left and right sides of the base, and the reflectors are located below the lifting plate.

[0011] More preferably, it also includes an anti-slip mat, with the anti-slip mat provided on the inclined block.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By pushing a set of locking plates, the wheel is positioned between the two locking plates of the set. After the four sets of locking plates are moved to the appropriate position, the four electric slide rails are activated, which drive the two electric sliders on the electric slide rails to move inward, thereby moving the locking plates. In this way, the two locking plates of the set can fix and limit the wheel of the vehicle, prevent the vehicle from slipping, and ensure the safety of the vehicle and the people below.

[0013] 2. The distance between the vehicle and the driver is measured by a rangefinder. When the vehicle exceeds a specific area, the rangefinder sends a digital signal to the controller, which then activates the alarm to warn the driver to move backward to the optimal position, thereby ensuring that the locking plate can secure the wheels.

[0014] 3. By activating the electric push rod, the electric push rod connecting plate and the two electric slide rails on the same vertical line move inward, thereby automatically adjusting the position of the locking plate. Attached Figure Description

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1: An intelligent lifting device, see [link / reference] Figures 1-7 As shown, the system includes a base 1, inclined blocks 2, lifting plates 3, sliding frames 4, limiting plates 5, hinge frames 6, limiting plates 7, sliding frames 8, a dual-axis motor 9, and a two-way lead screw 10. Inclined blocks 2 are symmetrically welded to the front side of the base 1. The dual-axis motor 9 is bolted to the bottom of the base 1. Limiting plates 5 are symmetrically welded to the bottom of the base 1, located on the left and right sides of the dual-axis motor 9. The output shaft of the dual-axis motor 9 is connected to the two-way lead screw 10 via a coupling. Sliding frames 4 are threaded onto both ends of the two-way lead screw 10. Two sliding frames 4 on the same two-way lead screw 10 slide within adjacent limiting plates 5. A hinge is used to connect the two sliding frames 4 on the same two-way lead screw 10. The frame 6 and base 1 are equipped with a sliding lifting plate 3. The middle of the lifting plate 3 is symmetrically and fixedly connected to a second limiting plate 7. The second sliding frame 8 is symmetrically and slidingly arranged inside the limiting plate. The two sliding frames 8 located in the same limiting plate are hingedly connected to the adjacent hinge frame 6. The frame also includes a positioning plate 11, an electric slider 12 and an electric slide rail 13. The left and right sides of the lifting plate 3 are symmetrically opened with a set of L-shaped slide grooves. Two mirrored L-shaped slide grooves form a set. The bottom left and right sides of the lifting plate 3 are symmetrically and slidingly arranged with electric slide rails 13. The electric sliders 12 are symmetrically installed on the electric slide rails 13. The electric sliders 12 slide in the electric slide rails 13. The top of the electric sliders 12 is fixedly connected to the positioning plate 11. The positioning plate 11 slides in the L-shaped slide groove. The upper part of the positioning plate 11 is located above the lifting plate 3.

[0025] See Figure 1 , Figure 6 and Figure 7 As shown, it also includes a protective pad 21, which is embedded in the inner side of the card plate 11.

[0026] See Figure 1 and Figure 2 As shown, it also includes a reflector 22. The reflector 22 is embedded on both the left and right sides of the base 1 and is located below the lifting plate 3.

[0027] See Figure 1 and Figure 2 As shown, it also includes an anti-slip pad 23, which is provided on the inclined block 2.

[0028] When the lifting platform is needed, the vehicle must first be driven onto the lifting platform 3 and stopped using the inclined block 2. Then, by pushing a set of locking plates 11, the wheels are positioned between the two locking plates 11 in the set. As the locking moves, the electric sliders 12 and electric slide rails 13 move along with the locking plates 11. After the four sets of locking plates 11 are moved to the appropriate positions, the four electric slide rails 13 are activated, causing the two electric sliders 12 on each electric slide rail 13 to move inward. This causes the electric sliders 12 to move the locking plates 11. The protective pad 21 reduces the pressure between the wheels and the locking plates 11, preventing indentations on the wheels. This allows for the movement of a set of locking plates 11. The two locking plates 11 fix and limit the vehicle's wheels to prevent slippage and ensure the safety of the vehicle and the people below. After the vehicle is fixed, the dual-axis motor 9 is started, so that the output shaft of the dual-axis motor 9 drives the bidirectional lead screw 10 to rotate, so that the bidirectional lead screw 10 drives the two sliding frames 4 on itself to move inward, so that the articulated frame 6 unfolds and drives the lifting plate 3 and the vehicle to move upward. At the same time as the articulated frame 6 unfolds, it drives the two sliding frames 8 to move inward, thus completing the lifting. The anti-slip mat 23 increases the friction between the wheels and the inclined block 2 to prevent the vehicle from slipping. The reflector 22 makes it easy to identify the position of the device at night.

[0029] Example 2: Based on Example 1, refer to Figure 2 As shown, it also includes a support plate 14, a rangefinder 15, a controller 16, and an alarm 17. The support plate 14 is fixedly connected to the rear side of the base 1. The rangefinders 15, which are infrared rangefinders, are symmetrically installed on the top of the support plate 14 by bolts. The controller 16 is installed on the top of the support plate 14 by bolts and is located between the two rangefinders 15. The alarm 17 is installed on the rear of the base 1 by bolts and is located in front of the controller 16.

[0030] When the vehicle is driving on the lifting platform 3, the distance between the vehicle and itself is measured by the rangefinder 15. When the vehicle exceeds the specific area, the rangefinder 15 sends a digital signal to the controller 16, causing the controller 16 to control the alarm 17 to sound an alarm, thereby warning the driver to move backward to the optimal position, so as to ensure that the wheels are between the two mirrored L-shaped grooves and that the locking plate 11 can fix the wheels.

[0031] See Figure 1 and Figure 7 As shown, it also includes a mounting plate 18, a connecting plate 19, and an electric push rod 20. Mounting plates 18 are welded to both sides of the lifting plate 3. Electric push rods 20 are bolted to the inside of the mounting plates 18. Connecting plates 19 are installed on the telescopic rods of the electric push rods 20. Connecting plates 19 are fixedly connected to two electric slide rails 13 on the same vertical line.

[0032] When it is necessary to move the positioning plate 11, the electric push rod 20 is activated, and the connecting plate 19 of the electric push rod 20 and the two electric slide rails 13 on the same vertical line move inward, thereby automatically adjusting the position of the positioning plate 11 without manual operation.
