Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a wind-resistant structure of lifting equipment used in construction engineering. Background Art

[0002] A crane is a multi-action lifting machine capable of vertically lifting and horizontally transporting heavy objects within a certain range. Some lifting equipment features intermittent motion, meaning that the corresponding mechanisms for retrieving, transporting, and unloading alternate within a single cycle. Cranes are becoming increasingly widespread in the market. A bridge crane is a type of lifting equipment used horizontally above workshops, warehouses, and material yards to lift materials. Because its ends rest on tall concrete columns or metal supports, it resembles a bridge. The bridge of a bridge crane runs longitudinally along tracks laid on elevated platforms on both sides, fully utilizing the space beneath it to lift materials without being obstructed by ground-based equipment. It is the most widely used and most numerous type of lifting machine. The bridge is the basic component of a bridge crane and consists of the main girder, end beams, and walkway. The main girder spans above the span and can be constructed in various configurations, including box-type, split-frame, web-plate, and round-tube. The main girder is connected to the end beams at both ends, and walkways and safety railings are installed on the outside of each main girder. The trolley travel mechanism is mounted on the platform on one side of the cab, while the auxiliary cable, a device that supplies power to the trolley's electrical equipment, is mounted on the other side. Guide rails are laid above the main beam for the trolley's movement. The entire overhead crane, pulled by the trolley travel mechanism, moves along the rails along the length of the workshop.

[0003] Bridge cranes are common heavy lifting equipment in industrial production. They have complex structures and large support areas. However, in windy weather, existing cranes are easily affected by lateral external forces, causing the fuselage to tilt, unstable walking, or even collapse, posing huge safety hazards to workers and equipment; cranes are easily sliding on the track due to strong winds, and the anti-slip structure of existing cranes is relatively simple; existing cranes cannot monitor wind speed and cannot alert safety personnel, which easily leads to safety hazards.

[0021] The iron wedge brake 41 includes a fixed plate 411, a side plate 412, a control column 413, a control motor 414, a joystick 415, a brake frame 416 and a friction block 417. The fixed plate 411 is bolted to the front side of the crane end beam 1. The fixed plate 411 fixes the iron wedge brake 411 to the crane end beam 1. There are two side plates 412, both welded to the front of the fixed plate 411. The top of the side plate 412 passes through a control column 413. The left end of the control column 413 is connected to a control motor 414. The control electrical appliance provides rotation for the control column 413.
