Description

TECHNICAL FIELD

[0001] The utility model belongs to tower crane technical field, concretely relates to a tower crane pedestal with high structural stability. BACKGROUND

[0002] The design principle of the tower crane pedestal is mainly based on ensuring the stability and carrying capacity of the tower crane during the working process. During the design process, the working load of the tower crane, the foundation condition, the environmental factors, and the safety requirements and other aspects need to be considered comprehensively. Through accurate calculation and analysis, the key parameters such as the size, shape, material and connection mode of the pedestal are determined to ensure that the pedestal can meet the stability and carrying capacity requirements of the tower crane. In terms of material selection of the tower crane pedestal, the strength, toughness, corrosion resistance and cost of the material need to be considered comprehensively. Commonly used materials include round steel, threaded steel and various high-quality steel materials. Among them, threaded steel is more outstanding in carrying capacity, stability and safety, especially suitable for complex geological conditions or scenarios where the tower crane needs to bear large load for a long time. Round steel is suitable for relatively fixed tower crane installation locations and good geological conditions due to its convenient construction and low cost.

[0003] The existing tower crane pedestal with high structural stability may have the following shortcomings during construction if the alignment structure is reinforced and supported and has certain lifting function: the stability of the tower crane pedestal is not high, which directly leads to the decline of the overall stability of the tower crane, increases the risk of overturning, especially under the action of external factors such as wind load and construction load, which is more likely to cause overturning accidents, further affecting the stability of the tower crane. Since the reinforcement does not have lifting function, the construction range of the tower crane will be limited, which cannot meet the construction requirements of different heights. The tower crane pedestal without lifting function cannot adjust the height of the tower crane according to the construction needs, which limits the construction flexibility. UTILITY MODEL CONTENTS
