A kind of marine crane installation method

Abstract

The invention relates to an installation method of a marine crane. After the marine crane is installed according to the steps of the installation method, the installation work of the crane can be completed in a small area, so that the rents of a field and equipment can be reduced, and the installation efficiency of the crane on water can be also improved; furthermore, the installation of the crane is completed by a lifting appliance in sequence, so that the requirement on the size of the construction field is low, and the construction difficulty is lowered; finally, an upper portal, a lower portal and a suspension arm are installed at the time of slack tide, so that the shake of a ship caused by factors such as wind waves can be effectively reduced, and the installation accuracy of the upper portal, the lower portal and the suspension arm can not be influenced. A kingpost is high, so that the construction environment is severer when a bearing is installed on the top of the kingpost; in order to guarantee the safety of constructors, a construction hanging basket is arranged, so that constructors can complete the installation work in an enclosed and safe area, and the safety of the constructors can be guaranteed.

Description

technical field [0001] The invention relates to a method for installing a ship crane, in particular to a method for installing a TSC-60-ton ship crane. Background technique [0002] At present, for the developed water system, there are many bridges arranged, and the water depth of the water system is relatively shallow. Therefore, there are great restrictions on the shipbuilding industry and ship navigation. However, at this stage, most of the marine cranes (especially the TSC-60-ton marine crane) are installed before launching, such as in the berth or dock. Therefore, due to the large size of the marine crane, when it needs to go through When there are many bridges and the water depth of the river is shallow, it is difficult to pass because it does not comply with the traffic regulations.

Problems solved by technology

[0002] At present, for the well-developed water system, there are many bridges arranged, and the water depth of the water system is relatively shallow. Therefore, there are great restrictions on the shipbuilding industry and ship navigation.

However, at this stage, most of the marine cranes (especially the TSC-60-ton marine crane) are installed before launching, such as in the berth or dock. Therefore, due to the large size of the marine crane, when it needs to go through When there are many bridges and the water depth of the river is shallow, it is difficult to pass because it does not comply with the traffic regulations.

[0003] In order to solve the above problems, the engineering personnel decided to install the crane after the ship is launched and passes through the necessary water system before installing the marine crane. However, the marine crane is installed after the ship is launched, and there will be more Difficulties: 1. Since the installation of the marine crane is carried out after the ship is launched, the construction work can only be carried out after docking at the wharf of an external unit. Therefore, the construction time needs to be shortened as much as possible to reduce the rental cost of the site and equipment; The size of the machine is too large. Therefore, when carrying out construction work on a wharf with a relatively narrow area, the equipment needs to be as close as possible to the crane arm operating range of the lifting equipment when entering the site, and the construction difficulty is increased; 3. Due to the need to carry out crane work outside the unit For the installation work, therefore, it is impossible to have multiple lifting equipment to complete the work at the same time as when the original construction unit was operating. Therefore, only a single lifting equipment can be used for construction work, which increases the difficulty of construction; 4. After the ship is launched, Due to the influence of natural factors such as tides and wind waves, the construction difficulty of cranes in water is far more difficult than that on land, especially the installation of crane booms.
