The invention discloses a bracket crane testing device and a use method thereof. The bracket crane testing device comprises a pre-buried foundation, a base, angle adjusting oil cylinders and an installation seat. The pre-buried foundation is connected to the bottom of the base and arranged underground. The installation seat is distributed at the top of the base, a first round installation hole isformed in the installation seat, and the bottom at the rear end of the installation seat is hinged to the base. The two angle adjusting oil cylinders are symmetrically distributed on the two sides atthe front end of the installation seat, the lower ends of the angle adjusting oil cylinders are hinged to the base, and the upper ends of the angle adjusting oil cylinders are hinged to the installation seat. The bracket crane testing device can simulate the non-perpendicularity of a bracket crane and the tank top of a storage tank and cooperate with a deflection measurer so that the deflection ofthe bracket crane can be detected, the structural strength of an upright of the bracket crane is checked, different specifications of installation seats can be installed, various function testing sites are provided for bracket cranes with different lifting capacities, and the bracket crane testing device has good interchangeability and specific property.
Description
technical field [0001] The invention relates to a crane test device and a use method thereof, in particular to a jib crane test device for an LNG storage tank top and a use method thereof. Background technique [0002] In recent years, as a high-quality clean fuel, liquefied natural gas (LNG for short) has the characteristics of high calorific value, cleanness and environmental protection, and high safety performance, and has wide application and development prospects in the energy field. In the liquefied natural gas industry chain, the storage of LNG is a key technology for its development and utilization. All countries in the world, including China, plan to build LNG receiving stations in the next few years. Although my country's liquefied natural gas industry started relatively late, every link of the entire LNG industry chain has developed in the past ten years, especially in the independent research and development of major LNG equipment. [0003] As the receiving term...
