A herringbone frame and a dynamic compaction machine with the same

Abstract

The invention discloses a propeller strut. The propeller strut comprises a rotary table, a main beam and a pull plate, wherein an upper hinging point hole of the main beam is hinged with an upper hinging point hole of the pull plate; a lower hinging point hole of the main beam is hinged with a front hinging point hole of the rotary table; a lower hinging point hole of the pull rod is detachably hinged with a rear hinging point hole of the rotary table; the pull plate is in an integrated structure and a hinging point hole is formed in the middle of the pull plate; the rotary table is provided with a transportation hinging point hole hinged with the hinging point hole. At the working state, a triangular bracket is formed by the rotary table, the main beam and the pull plate; the pull pate is in the integrated structure so that a connection device is omitted; when the propeller strut works, the pull plate does not generate vibration and the stability of the whole propeller strut is improved; at the conveying state, the lower hinging point hole of the pull plate and the rear hinging point hole of the rotary table are detached, the main beam is rotated backwards around the front hinging point hole of the rotary table under the assistance of a crane; the lower end of the pull plate moves forwards and the upper end moves downwards, and after falling in place, the hinging point hole of the pull plate is connected with the transportation hinging point hole to fold the propeller strut; the propeller strut can be folded and has good stability.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a herringbone frame. The present invention also relates to a dynamic compaction machine provided with the above-mentioned herringbone frame. Background technique [0002] When the dynamic tamping machine is working, the rammer is raised to a certain height, and then put down, the rammer makes a free fall movement under the action of its own gravity, hammering the ground. [0003] The dynamic compaction machine includes a tamper, a wire rope, a luffing pulley block, a jib frame, a herringbone frame and a turntable. Both the boom frame and the herringbone frame are set on the turntable. When the machine is working, the luffing pulley block pulls the boom to the working angle and keeps it still. The steel wire rope lifts the rammer to the head of the boom and puts it down, then lifts it up and puts it down again, hammering the ground repeatedly. The herringbone frame...

Problems solved by technology

[0008] The single pull plate 21' and the double pull plate 22' of this gable frame are connected by two pin shafts, so that the gable frame can be folded during transportation. If the shaking is large, the gap at the connection will cause the herringbone to vibrate, increasing the shaking range of the herringbone, affecting the stability of the herringbone, and then affecting the stability of the boom, which will also affect the stability of the dynamic compaction machine. Will have a certain impact, there is a security risk
