Problems solved by technology

Among them, when the movable pulley block is removed to connect the lug plate of the lower jib frame, due to the tension of the luffing wire rope, the movable pulley block will move to one side of the lower jib frame, which increases the connection between the movable pulley block and the stay rope. Difficulties: The lug plate of the movable pulley block is in a free state, there is no installation reference for the two dynamic connections, and it takes a long time during the transition installation process, which is inefficient

Abstract

The invention discloses a luffing boom and a dynamic compaction machine provided with the luffing boom. The luffing boom comprises a pulley block and a lower section boom, wherein a fixed ear plate is arranged on the lower section boom; and a connecting ear plate for connecting a guy rope is arranged on the pulley block, and a transition ear plate connected with the fixed ear plate is also arranged on the pulley block. By use of the luffing boom and the dynamic compaction machine provided by the invention, the pulley block and the lower section boom are not disconnected before the guy rope is mounted, but the fixed ear plate and the transition ear plate, which are well connected, are used as a basis to achieve a positioning effect and quickly connect the guy rope to the connecting ear plate and a pulley of the pulley block, and finally, the fixed ear plate and the transition ear plate are disconnected. Finally, the aim of quickly mounting the guy rope is achieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to a luffing jib and a dynamic compaction machine provided with the luffing jib. Background technique [0002] The dynamic compaction machine has been widely used in port reclamation projects, road and railway subgrade construction and airport construction projects. [0003] The jib of the dynamic compaction machine is a luffing jib. The luffing refers to the angle of the main arm. The raising of the main arm is called the starting amplitude, and the lowering of the main arm is called the falling amplitude. [0004] Wherein, the luffing jib of the dynamic compaction machine includes a luffing device, a top jib, an intermediate jib and a lower jib, and the luffing device and the top jib are connected by a stay rope. The luffing pulley device in the luffing device includes a fixed pulley block and a movable pulley block. A movable pulley is a pulley whose...
