Non-Newtonian damping wind-resistant gantry crane and debugging method thereof

Abstract

The invention discloses a non-Newtonian damping wind-resistant gantry crane and a debugging method thereof. The gantry crane comprises a hanging bracket, rollers and a retarding device arranged in thehanging bracket of the gantry crane; the hanging bracket is of a hollow structure, the retarding device is movably connected with the inner wall of the hanging bracket, a plurality of ventilation holes are formed in the outer wall of the hanging bracket, and the ventilation holes are located in the positions, away from the rollers, of the retarding device; the retarding device comprises a retarding chamber and retarding wheels, non-Newtonian liquid is injected into the retarding chamber, the retarding wheels are fixed in the retarding chamber, a first connecting rod is fixed to the corresponding retarding wheel, one end of each first connecting rod is fixed to an eccentric position on the corresponding retarding wheel, and the free end of each first connecting rod extends out of the retarding chamber and points to the corresponding roller position; and a second connecting rod is fixed to the corresponding roller, the fixed end of each second connecting rod is connected to an eccentricposition on the corresponding roller, and the free end of each second connecting rod extends into the hanging bracket and points to the free end of the corresponding first connecting rod. According to the non-Newtonian damping wind-resistant gantry crane and the debugging method thereof, the gantry crane slowly moves in typhoon weather through the non-Newtonian liquid, and toppling is prevented.

Description

technical field [0001] The invention relates to the field of cargo yard hoisting equipment and disaster prevention, in particular to a non-Newton damping wind-resistant gantry crane and a debugging method thereof. Background technique [0002] The gantry crane is a deformation of the bridge crane, also known as the gantry crane. It is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargoes, and bulk cargoes. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have outrigger cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards. [0003] Gantry cranes can be divided into the following types according to the form of the main girder: 1. Single main girder, single main girder gantry ...

AI Technical Summary

Problems solved by technology

The L-type is easy to manufacture and install, has a good stress condition, and its own mass is small, but the space for hoisting goods through the outriggers is relatively small.

The C-shaped legs are inclined or curved, the purpose is to have a large horizontal space so that the goods can pass through the legs smoothly; 2. Double main girders, double main girder gantry cranes have strong bearing capacity, large span, and good overall stability There are many varieties, but its own quality is larger than that of the single main girder gantry crane with the same lifting capacity, and the cost is also higher. According to the different structure of the main girder, it can be divided into two forms: box girder and truss, generally more It adopts a box-shaped structure and is welded into a box-type structure with steel plates. It has the characteristics of high safety and high rigidity. It is generally used for large-tonnage and super-large-tonnage gantry cranes. The box girder also has high cost, heavy weight, and wind resistance. Poor and other disadvantages

[0004] Due to its high center of gravity and large windward surface, the existing box-girder gantry cranes are prone to being blown down by the wind in windy weather, especially in seaside ports, causing greater damage and impact, and the existing anti-corrosion Most of the dumping measures are to use the fixing device to completely fix the gantry crane. Due to its high center of gravity, the anti-dumping ability of the complete fixation is not as good as that of the application to make it move slowly.
