Description

Technical Field

[0002] In the process of mechanical design and production, a large number of plates will be used to support the needs of mechanical design. Due to the needs of mechanical design, the plates used in the mechanical design process require high-quality materials to support them. This makes the plates used in mechanical design heavier, so mechanical equipment will be used to lift the plates.

[0003] In the prior art, a lifting device is usually provided with an extended lifting arm to lift the plates placed on the ground. However, since the lifting arm is set in the air, if the weight of the lifted plates is large, it is easy to cause the device to tip over. If a support plate is fixed on the base under the lifting wall, although it can play a role of stable support, it makes it impossible for the lifting arm to move to the position directly above the plates, thereby failing to easily complete the lifting work.

If the L-shaped bracket A3 is arranged directly above the moving seat 1, it is impossible to ensure that the lifting mechanism is placed directly above the plate, thereby affecting the lifting of the plate; the moving seat 1 is arranged below the lifting seat 2, and a power component A for driving the lifting seat 2 to rise and fall is installed on the moving seat 1. The power component A includes a servo motor B91 and a threaded rod B92. A top plate 22 is arranged above the lifting seat 2.

The servo motor B91 is installed on the moving seat 1. The threaded rod B92 is connected to the output shaft of the servo motor B91, and the lifting seat 2 is threadedly connected to the threaded rod B92; the lifting mechanism is installed on the moving seat 1.

[0024] The stabilizing assembly includes a rotating rod 4, a counterweight 5, a rotating seat A6, a rotating seat B7 and a power assembly B. The rotating seat B7 is fixed on the L-shaped bracket A3. The end of the rotating rod 4 is rotatably mounted on the rotating seat B7. The rotating seat A6 is fixed on the lifting seat 2.

The power assembly B includes a servo motor A81 and a threaded rod A82. A T-shaped slider 27 is fixed to the counterweight 5. A slide groove 401 for the T-shaped slider 27 to slide is provided on the rotating rod 4. The threaded rod A82 is rotatably installed on the inner side of the slide groove 401. The T-shaped slider 27 is threadedly connected to the threaded rod A82. The servo motor A81 is installed at the end of the rotating rod 4 and its output shaft is connected to the threaded rod A82.

[0025] In this embodiment, during the lifting process, the power arm can be adjusted according to the mass of the hoisted plate, that is, the moving position of the counterweight 5 on the rotating rod 4 can be adjusted. The counterweight 5 can be driven to move through the provided power component B. When the counterweight 5 moves to the side away from the rotating seat A6, since the mass of the counterweight 5 remains unchanged, the distance from the rotating seat A6 becomes larger, so the torque gradually increases. As the mass of the hoisted plate increases, the torque increases accordingly, thereby ensuring the stability of the entire device and preventing the device from tipping over during the lifting process.
