Description

Technical Field

[0001] The utility model relates to the technical field of stone processing machinery, in particular to an anti-falling mechanism. Background Art

[0002] Natural stone is divided into slate and granite according to its physical and chemical properties. Artificial stone is divided into terrazzo and synthetic stone according to the process. Terrazzo is forged from cement, concrete and other raw materials; synthetic stone is made from crushed natural stone, with adhesives and other materials, and then pressurized and polished. The latter two are artificially made, so their strength is not as high as that of natural stone. Stone is a high-end product of building decoration materials. Natural stone can be roughly divided into granite, slate, sandstone, limestone, volcanic rock, etc. With the continuous development and progress of science and technology, artificial stone products are also constantly changing with each passing day, and their quality and beauty are no less than natural stone. With the development of architectural design, stone has long become one of the important raw materials for construction, decoration, roads and bridges.

[0003] Due to the large specifications of natural stone processing, the mechanical equipment is relatively heavy. The lifting mechanism of heavy cutting machinery generally uses screw rods, nut mechanisms, and threaded pair mechanisms. They will gradually wear out over time and cause failure, which will cause the risk of the machinery falling.

[0004] To prevent such accidents, we developed an anti-fall mechanism to solve this problem. Utility Model Content

[0007] As a preferred technical solution of the utility model, the screw rod passes through the upper bearing seat and is provided with a working nut and an anti-falling movable nut, and the screw rod is connected to the working nut and the anti-falling movable nut.

[0008] As a preferred technical solution of the utility model, the working nut is connected to the lifting frame, and after the anti-falling movable nut is connected to the nut movable seat, a gap is reserved between the lifting frame to prevent the anti-falling movable nut from rotating.

[0009] As a preferred technical solution of the present utility model, the bottom end of the screw rod is connected to the lower bearing seat, and the screw rod is rotatably connected to the lower bearing seat.

[0010] As a preferred technical solution of the present utility model, bolts are installed between the lower bearing seat and the column, and the lower bearing seat is connected to the column through the bolts.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model is an anti-fall mechanism. When the working nut of the anti-fall mechanism arranged in the device fails, the lifting frame will fall down. At this time, the anti-fall movable nut will take effect to support the lifting frame to prevent mechanical damage and accidents caused by falling. In addition, it is ensured that the anti-fall nut can support the frame to prevent major damage and accidents when the working nut fails and causes the frame to fall, thereby playing an effective safety protection effect.
