AI Technical Summary
The existing polar environmentally friendly transport ship's Keling crane boom bracket design occupies a large area of hatch cover and is inefficient in space, making it difficult to meet the maintenance and maintenance needs of many Keling cranes.
A mobile Keling hanging boom bracket is designed, including a truss structure, a straight ladder for lifting hook operation, a lifting eye plate, a sealing eye plate, a fast plug and a base. The upper and lower sealing eye plates are connected by a wire rope. The quick plug and the base are connected by a twist lock to achieve simple installation and fixation of the boom bracket.
This design greatly reduces the number of boom brackets and the deck area occupied. Only one set of boom brackets can meet the maintenance needs of four Keling cranes, save space for more container layout, and improve transportation efficiency.

Abstract
Description
Technical Field
[0001] The invention relates to the field of polar environmentally friendly transport ships, and in particular to a mobile crane arm bracket for polar environmentally friendly transport ships. Background Art
[0002] At present, with the global warming, the Arctic sea ice is melting faster, and the coverage of Arctic Ocean sea ice in summer continues to decrease. We are deeply involved in all-round pragmatic cooperation in polar waterways, resources, infrastructure, etc., and strive to build Arctic utilization. The development of polar environmental protection multi-purpose ships has come into being. Crane is the most important functional equipment of the whole ship. The design of its boom trailer is particularly important on the main deck where the hatch cover area occupies more than 80%. Summary of the invention
[0003] The purpose of the present invention is to provide a mobile crane arm bracket for a polar environmentally friendly transport ship which has a simple structure, occupies a small space and is highly practical.
[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a mobile crane arm bracket for a polar environmentally friendly transport ship, comprising a truss structure (1), a straight ladder (2) for hook removal operation, a lifting eye plate (3), an upper end sealing eye plate (4), a quick plug (5), a lower end sealing eye plate (6) and a base (7), wherein the straight ladder (2) for hook removal operation is installed on the truss structure (1), the lifting eye plate (3) and the upper end sealing eye plate (4) are installed on the top of the truss structure (1), the quick plug (5) is installed on the bottom foot of the truss structure (1), the lower end sealing eye plate (6) and the base (7) are respectively fixed on the main deck of the ship, and the upper end sealing eye plate (4) and the lower end sealing eye plate (6) are connected by a steel wire rope (8).
[0005] The quick plug (5) is connected to the base (7) via a twist lock (9).
[0006] There are two lifting eye plates (3).
[0007] There are four upper end sealing eye plates (4) and four lower end sealing eye plates (6).
[0008] There are four quick plugs (5) and four bases (7).
[0009] The mobile boom bracket of a polar environment-friendly transport ship of the present invention has a simple structure, occupies a small space, is highly practical, and reduces the number of boom brackets and the occupied deck area to the greatest extent, thereby loading more cargo, breaking the configuration mode of one crane and one bracket. Only one set of boom brackets is used to meet the inspection and maintenance work requirements of four cranes, and only one space is occupied to store the boom brackets. The saved space can be used to arrange more containers, thereby improving the transport efficiency of the ship. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 The present invention is a structural schematic diagram of a mobile crane arm bracket for a polar environmentally friendly transport ship.

[0013] like Figure 1 and Figure 2 As shown, the boom bracket of the mobile crane of the polar environmental protection transport ship includes a truss structure 1, a straight ladder 2 for hook removal operation, two lifting eye plates 3, four upper end sealing eye plates 4, four quick plugs 5, four lower end sealing eye plates 6 and four bases 7. The two lifting eye plates 3 and the four upper end sealing eye plates 4 are respectively installed on the top of the truss structure 1, the four quick plugs 5 are installed on the bottom of the truss structure 1, the four lower end sealing eye plates 6 and the four bases 7 are respectively fixed on the main deck of the ship, the assembled boom bracket is lifted to the top of the base 7, the quick plug 5 and the base 7 at the bottom of the boom bracket are connected by a twist lock 9, the four upper end sealing eye plates 4 and the four lower end sealing eye plates 6 are connected by a wire rope 8, the boom bracket is sealed as a whole in a fixed position, and the ship's own crane and lifting equipment are used to use the lifting eye plate 3 to lift the assembled The boom bracket is lifted to a certain height and moved to a designated position, and then the crane hook head is directed to gradually descend until the four quick plugs 5 at the bottom of the boom bracket are aligned with the dovetail slot sockets on the hatch cover, and the quick plug 5 at the bottom of the boom bracket is connected to the dovetail slot socket by twist lock 9, and then the crane's own sling is removed. The boom bracket has four actual use positions. The mobile crane boom bracket of the polar environmental protection transport ship of the present invention has a simple structure, small space occupation, and strong practicality. It minimizes the number of boom brackets and the occupied deck area to the greatest extent, thereby loading more cargo and breaking the one-crane-one-bracket configuration mode. Only one set of boom brackets is used to meet the inspection and maintenance needs of four cranes, and only one space is occupied to store the boom bracket. The saved space can be used to arrange more containers, thereby improving the transportation efficiency of the ship.
