[0021] Example

[0022] See also Figure 1 - Figure 4 The present application provides a technical solution: a hoisting device for a large mold, comprising a telescopic scissor fork 110, a lateral shifting trolley 120, an electric hoist 130, a connecting chain 140 and a manned cage 150, wherein the lateral shifting trolley 120 is fixed on the lower surface of the upper frame of the telescopic scissor fork 110, the lateral shifting trolley 120 is installed on a gantry, the lateral shifting trolley 120 is arranged to move the manned cage 150 laterally on the gantry, and the upper end of the electric hoist 130 is rotatably arranged on the upper frame of the telescopic scissor fork 110;

[0023] One end of the connecting chain 140 is sleeved on the telescopic scissors fork 110, and the other end of the connecting chain 140 is sleeved on the hook of the electric hoist 130. It also includes a first U-shaped ring 190 and a second U-shaped ring 191. The first U-shaped ring 190 and the second U-shaped ring 191 are fixed at different positions of the telescopic scissors fork 110. The upper end of the electric hoist 130 is rotatably set on the second U-shaped ring 191. One end of the connecting chain 140 is sleeved on the first U-shaped ring 190. The setting of the first U-shaped ring 190 and the second U-shaped ring 191 facilitates the installation of the electric hoist 130 and the connecting chain 140. Two connecting chains 140 are set on one side of the telescopic scissors fork 110. The two connecting chains 140 and the lower frame of the telescopic scissors fork 110 form a triangular structure, so that the manned cage 150 can move up and down more smoothly.

[0024] The manned cage 150 is fixed on the lower surface of the lower frame of the telescopic scissors fork 110, and also includes a handrail 160. The handrail 160 is fixed on the lower surface of the telescopic scissors fork 110. The handrail 160 and the manned cage 150 are arranged correspondingly. The arrangement of the handrail 160 is convenient for the staff to stabilize their bodies and improve the personal safety of the staff. It also includes a U-shaped plate 170. The U-shaped plate 170 is fixed on the lower surface of the telescopic scissors fork 110. The upper end of the manned cage 150 passes through the U-shaped plate 170. The arrangement of the U-shaped plate 170 facilitates the installation of the manned cage 150 on the telescopic scissors fork 110. An operating table 180 is arranged on the manned cage 150. The operating table 180 and the electric hoist 130 are electrically connected together. The arrangement of the operating table 180 facilitates the operation of the up and down movement of the manned cage 150. The connection method between the electric hoist 130 and the manned cage 150 is a scissors-fork type rigid connection. The purpose of this rigid connection is to reduce the swing during operation and higher safety.

[0025] Specifically, the working principle of the lifting device for large molds is as follows: when in use, the transverse moving trolley 120 is installed on the gantry, and the electric hoist 130 can realize the up and down movement of the manned cage 150. At the same time, the telescopic scissors fork 110 will also shrink or extend, so that people can be loaded. The setting of the telescopic scissors fork 110 reduces the swing during operation and has higher safety. The electric hoist 130 and the transverse moving trolley 120 can be controlled manually through the operating table 180. The transverse moving trolley 120 realizes the transverse movement of the manned cage 150 on the gantry. The lifting device for large molds is more suitable for long-term work. The manned cage 150 covers downward from the air, and the coverage area is larger. For equipment with a wider frame and a large upper plane, its operating dimensions are difficult to achieve with ordinary aerial platforms, and humans standing on the cage can control the multi-dimensional operation of the device, and perform related work such as installation, laying, and maintenance of the equipment. It is safe and efficient, bringing users a better use experience.

[0026] It should be noted that the specific models and specifications of the transverse trolley 120, the electric hoist 130 and the operating platform 180 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The power supply and principle of the transverse moving trolley 120, the electric hoist 130 and the operating platform 180 are clear to those skilled in the art and will not be described in detail here.

[0028] The above description is only an embodiment of the present application and is not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
