Anti-typhoon method for portal crane and special equipment thereof

Abstract

The invention mainly relates to an anti-typhoon method for a portal crane and a special equipment thereof. The method is characterized by comprising: 1) collecting local typhoon data and forecast information and making a specific solution; 2) running the stopped portal crane to a preset position before a typhoon comes; 3) laying ground anchors and cable wind ropes; and 4) fixing a hook. According to the special device, ground anchors are arranged in rigid leg foundation pits of the rigid legs and flexible leg foundation pigs of the flexible legs of the portal crane, each ground anchor has a cable wind interface reserved on the ground; symmetric cable wind ropes are arranged on the front and back sides of the rigid legs and the front and back sides of the flexible legs of the portal crane; and an iron boots and ejecting wheels are placed under the big running wheels of the portal crane. According to the analysis on loads on different portal cranes under different wind scales, specific protective measures are adopted, the overturning moment of the portal crane is reduced, related protective main points are defined, and the equipment can resist grade 11 or above typhoons.

Description

Technical field: [0001] The present invention mainly relates to a typhoon-proof method and a special device for a gantry crane, aiming at the need of protecting a gantry crane (also referred to as a gantry crane) from a large typhoon in a coastal area. It belongs to the technical field of crane safety. Background technique: [0002] The general-purpose gantry crane is composed of main structures such as a bridge frame, outriggers, and a large running trolley. It is also called a gantry crane. It is a lifting machine frequently used in municipal, wharf, and power plant construction sites. It has high operating efficiency and low cost. The height of the bridge frame of the crane usually ranges from 10 to 30m. Compared with other types of cranes, the gantry crane is top-heavy, has a large windward area, and poor stability. When working outdoors along the coast, strict typhoon protection measures are required. [0003] In recent years, coastal areas have been frequently hit by ...
