Embodiment 1

[0025] The embodiment of the present invention provides a boom assembly of a ship crane. The ship crane includes a crane turntable and a boom assembly, see figure 1 , Boom components include main boom 1, secondary boom 2, primary oil cylinder 3, secondary oil cylinder 4, secondary hook 5, main hook 6, guide hook device 7, main crane wire rope 8, main crane guide rope pulley group 9. Secondary hoisting steel wire rope 10, and secondary hoisting guide rope pulley group 11.

[0026] In this embodiment, the hoist turntable ( figure 1 Not shown) is connected to the bottom end of the main boom 1. The secondary boom 2 is hinged on the top of the main boom 1. The cylinder portion 31 of the primary cylinder 3 is hinged to the bottom end of the main boom 1, and the piston rod portion 32 of the primary cylinder 3 is hinged to the middle of the cylinder portion 41 of the secondary cylinder 4. The cylinder part 41 of the secondary cylinder 4 is hinged to the middle of the main boom 1, and th...

Embodiment 2

[0046] The embodiment of the present invention provides a ship crane, which includes a crane turntable and the boom assembly shown in the first embodiment.

[0047] In the embodiment of the present invention, the secondary hook is set on the secondary boom, and the primary and secondary hydraulic cylinders are used to drive the secondary boom to realize the function of the knuckle boom type crane. By setting the primary hook on the main boom, And use the primary and secondary oil cylinders to pull the secondary boom to retract to realize the function of the main boom crane. The functions of two cranes are integrated on a ship crane, which expands the applicable operating conditions of the ship crane and has wide applicability. .

Abstract

The invention discloses a boom assembly of a ship crane and the ship crane, which belong to the technical field of ships. The boom assembly includes the main boom, the secondary boom, the primary cylinder, the secondary cylinder, and the secondary hook. The secondary boom is hinged at the top of the primary boom, and the cylinder part of the primary cylinder is hinged at the bottom of the primary boom. The piston rod part of the first stage oil cylinder is hinged at the middle part of the oil cylinder part of the second stage oil cylinder, the oil cylinder part of the second stage oil cylinder is hinged at the middle part of the main boom frame, and the piston rod part of the second stage oil cylinder is hinged at the middle part of the secondary boom frame; the boom assembly It also includes the main hook, the guide hook device, the main hoisting wire rope, the main hoisting guide rope pulley block, the secondary hoisting wire rope, and the secondary hoisting guide rope pulley block. On the jib frame, the hoisting end of the main hoisting steel wire rope bypasses the main hoisting guide rope pulley block and the guide hook device to connect with the main hook, and the hoisting end of the secondary hoisting wire rope bypasses the secondary hoisting guide rope pulley block and the secondary boom frame to connect with the secondary hook. The invention has wide applicability.

Description

Technical field [0001] The present invention relates to the technical field of ships, in particular to a boom assembly of a ship crane and a ship crane. Background technique [0002] Ship cranes are machinery used for the lifting, loading and unloading of cargo of marine transportation vessels. Ship cranes are divided into knuckle boom cranes and straight boom cranes according to their structure. The boom of the knuckle boom crane is folded when not in use, and stretched when in use. It has the characteristics of flexibility and convenience, but its load capacity is poor; the boom of the straight boom crane has always been longitudinally installed and has overload The characteristics of strong ability, but not flexible and convenient. The functions of the knuckle boom crane and the straight boom crane are relatively single, and their respective applicable operating conditions are limited. Summary of the invention [0003] In order to solve the problem that the functions of the ...
