[0030] like Figure 1 and Figure 2As shown, the lifting structure 100 with a protective function includes a lifting assembly, a protective block 2 and a driving member 3. The lifting assembly includes a fixed seat 11 and a lifting seat 12. The lifting seat 12 is slidably connected to the fixed seat 11, and a workpiece 5 is installed at the bottom end of the lifting seat 12; the protective block 2 is located on one side of the lifting assembly and is installed on the lifting seat 12; the driving member 3 is located on one side of the lifting assembly and is arranged on the same side as the protective block 2, the driving member 3 is installed on the fixed seat 11, and the lifting seat 12 is used to rise or fall relative to the fixed seat 11 to drive the protective block 2 and the workpiece 5 to rise or fall, and the output shaft of the driving member 3 is used to extend into the bottom of the protective block 2 after the protective block 2 rises to limit the protective block 2.

[0031] In the above embodiment, the lifting structure 100 with a protective function includes a lifting assembly, and the lifting assembly includes a fixing seat 11 and a lifting seat 12, wherein the fixing seat 11 can be installed on an external device such as a wall of a factory building, a mechanical device or an operating table to play a supporting and fixing role, and the fixing seat 11 extends vertically, and the vertical direction is Figure 1 In the up and down directions referred to in the figure, the lifting seat 12 is slidably connected to the fixed seat 11, and the lifting seat 12 can rise or fall relative to the fixed seat 11. Specifically, the lifting seat 12 can be raised or lowered relative to the fixed seat 11 by an external driving device, such as a hydraulic cylinder or a hydraulic jacking device to achieve the rise or fall of the lifting seat 12, or a motor to drive the lifting seat 12 to rise or fall relative to the fixed seat 11, and an external manipulator can also be used to make the lifting seat 12 rise or fall relative to the fixed seat 11, which is not limited in this embodiment. The workpiece 5 is installed at the bottom end of the lifting seat 12, so that when the lifting seat 12 rises or falls, the lifting seat 12 drives the workpiece 5 to rise or fall. The protective block 2 is located on one side of the lifting assembly, such as Figure 1 As shown, the protection block 2 is installed on the front side of the lifting seat 12, and the driving member 3 is arranged on the same side as the protection block 2 and installed on the front side of the fixed seat 11. The driving member 3 in this embodiment can be a cylinder. When the lifting seat 12 drives the protection block 2 to rise, until the protection block 2 rises to the top of the driving member 3, the output shaft of the driving member 3 extends out and extends to the bottom of the protection block 2, so that the output shaft of the driving member 3 can protect the lifting seat 12. When the external driving device cannot support the lifting seat 12 under certain unexpected circumstances, causing the lifting seat 12 to fall suddenly, the output shaft of the driving member 3 can abut against the bottom of the protection block 2, thereby preventing the lifting seat 12 from falling, so as to protect the workpiece 5 installed at the bottom of the lifting seat 12. Figure 1 When the lifting seat 12 needs to be lowered, the output shaft of the driving member 3 can be retracted, as shown in FIG. Figure 2As shown, the protection block 2 is released from the position limit. The lifting structure 100 with protection function in this embodiment has a simple structure. The driving member 3 cooperates with the protection block 2. When the output shaft of the driving member 3 is extended, the lifting seat 12 can be prevented from accidentally falling, thereby protecting the safety of the workpiece 5. When the workpiece 5 needs to move downward normally and does not need protection, the output shaft of the driving member 3 is retracted to release the position limit of the protection block 2 and the workpiece 5. The lifting structure 100 with protection function in this embodiment can work reliably in harsh environments such as high temperature and low temperature, and meet the safety protection requirements.

The abutting portion 21 and the mounting portion 22 are connected to each other and form an L-shaped structure, so that a step surface is formed at the connection between the abutting portion 21 and the mounting portion 22. The step surface is the bottom surface of the abutting portion 21, and the output shaft of the driving member 3 is used to abut against the step surface. Specifically, when the lifting seat 12 accidentally falls, the output shaft of the driving member 3 can abut against the bottom surface of the abutting portion 21 to provide a supporting force for the abutting portion 21, thereby preventing the lifting seat 12 from falling. The mounting portion 22 is installed on the lifting seat 12 to fix the abutting portion 21.

[0033] In other embodiments, the protective block 2 may also be provided with only the abutment portion 21, and the abutment portion 21 may be directly installed on the lifting seat 12, or the protective block 2 may also be a U-shaped structure, by opening a groove on the side of the protective block 2 facing the driving member 3 for the output shaft of the driving member 3 to extend into.
