[0038] Please refer to Figure 1 、 Figure 2 and Figure 4 The lifting structure 20 includes a support frame 210, a hydraulic cylinder 220, a connecting plate 230 and a clamping assembly 240. The support frame 210 is arranged on one side of the support frame 110. The hydraulic cylinder 220 is installed in the support frame 210. The connecting plate 230 is connected to the movable end of the hydraulic cylinder 220. The clamping assembly 240 is arranged on one side of the connecting plate 230.

[0039] In specific settings, the clamping assembly 240 includes a fixed frame 241, a servo motor 242, a bidirectional lead screw 243, two lead screw nut pairs 244 and a clamping plate 245. The fixed frame 241 is connected to the connecting plate 230. The servo motor 242 is installed on one side of the fixed frame 241.

[0043] The working principle of the construction engineering machinery transfer device: When using the construction engineering machinery transfer device, through the setting of the universal wheels 140, the device is moved to a suitable position. By pulling the pull block, the sliding rod 131 and the slider 132 are driven to move, and the spring 133 is compressed, so that the sliding rod 131 is disengaged from the clamping connection with the L-shaped sliding plate 120. The L-shaped sliding plate 120 is pulled to move within the support frame 110. Through the reset of the spring 133, the sliding rod 131 is clamped with the second card slot. At this time, the device is pushed, so that the construction machinery is placed below the clamping plate 245. The hydraulic cylinder 220 drives the connecting plate 230 and the clamping assembly 240 to move downward. By starting the servo motor 242 to drive the bidirectional lead screw 243 to rotate, the two lead screw nut pairs 244 and the clamping plate 245 clamp the construction machinery. Through the reset of the hydraulic cylinder 220, the construction machinery is lifted. At this time, the L-shaped sliding plate 120 is reset, and the hydraulic cylinder 220 is started to drive the construction machinery to move, so that the bottom of the construction machinery fits with the L-shaped sliding plate 120. At this time, the device is moved to facilitate the transfer of the construction machinery.

[0044] It should be noted that the specific model specifications of the hydraulic cylinder 220 and the servo motor 242 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0045] The power supply and its principle of the hydraulic cylinder 220 and the servo motor 242 are clear to those skilled in the art, and will not be elaborated in detail here.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
