Problems solved by technology

The bigger problem is that if the load needs to be released suddenly during the lifting process like a dynamic tamping machine, under the influence of the deformation and energy storage of the wire rope and the boom, it will cause the boom to tilt backward and vibrate

Abstract

The invention relates to a dynamic compactor capable of realizing the amplitude-variable followup of an A-bracket with an arm support, which is characterized in that a followup A-bracket is mounted on a dynamic compactor rotating platform, an amplitude-variable draw rod is arranged between an inner diagonal rod and an arm support, a swing arm mechanism is arranged at the lower parts of the amplitude-variable draw rod and the inner diagonal rod, the swing arm mechanism is composed of a swing arm rack and a telescopic oil cylinder, and the followup A-bracket forms linkage with the amplitude-variable draw rod by the swing arm mechanism. Wire ropes of a hoisting mechanism are connected with a dynamic compactor weight through a pulley at the top end of the followup A-bracket and a pulley at the top end of the arm support, so that the quantity of front wire ropes at the top end of the arm support is the same with that of back wire ropes at the top end of the arm support. When the amplitude-variable draw rod drives the arm support to realize an amplitude-variable process, the swing arm mechanism connected with the followup A-bracket synchronously drives the followup A-bracket to swing. The amplitude-variable followup of the followup A-bracket with the arm support is realized, so that the stress on the arm support of the dynamic compactor is more reasonable, the stress balancing of the arm support can be realized to the greatest extent, the structural stress of the arm support can be improved, the self-weight of the arm support can be reduced, and the dynamic compaction operating performance of the arm support and the complete machine can be improved.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, and relates to a dynamic compaction machine in which a herringbone frame and a jib frame vary in amplitude. Background technique [0002] At present, the commonly used crawler cranes (including dynamic compaction machines) have fixed herringbone frames of a certain height and special hoisting wire rope luffing mechanisms for jib luffing. During luffing, the luffing frames There is no relative movement during the luffing process. The luffing mechanism pulls and releases the jib independently by changing the length of the luffing wire rope to realize the luffing of the jib. There is no linkage between the herringbone frame and the jib luffing. In addition, the head of the jib is not only affected by the direction-keeping force of the luffing steel wire rope, but also by the force of the front magnification pulley block of the jib end of the lifting wire rope and the force of the hoisting...
