Dynamic compaction machine and door frame device thereof

Abstract

The invention discloses a door frame device for a dynamic compaction machine. The door frame device comprises a beam, swing legs and limiting assemblies; one ends of the limiting assemblies are fixed on the beam and the other ends of the limiting assemblies are fixed on the swing legs; the limiting assemblies are used for limiting the relative positions of the beam and the swing legs. Accordingly, in the process that the door frame device shifts along with the dynamic compaction machine, the relative positions of the beam and the swing legs are fixed by the limiting assemblies, so that the irregular swing of the swing legs, which is relative to the beam, is avoided and accordingly the position between the two swing legs and the position between the swing legs and the beam do not change when the swing legs fall back into the ground again, the swing legs do not need to be straightened and positioned again, and accordingly the working efficiency is improved. Meanwhile the swing legs do not need to be straightened manually and accordingly the labor intensity of an operator is reduced, the excessive straightening caused by a human is avoided, and the positioning accuracy of the swing legs is improved. The invention also discloses the dynamic compaction machine comprising the door frame device.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a door frame device for a dynamic compaction machine. The present invention also relates to a dynamic compaction machine comprising the above-mentioned mast device. Background technique [0002] In construction projects, dynamic tamping machines are often used to compact the loose soil. Specifically, the rammer of the dynamic tamping machine is lifted to a relatively high height and then falls freely to give the foundation a strong impact and vibration, making the soil The body structure is destroyed, the pores are compressed, the soil is partially liquefied, the pore water and gas are discharged through the cracks, and the foundation soil is consolidated under the new condition, thereby increasing the bearing capacity and reducing its compressibility, and improving the uniformity of the soil layer, reducing Differential settlements that may arise in the future. ...

AI Technical Summary

Problems solved by technology

During installation, it is necessary to first connect the balance beam and cross beam 111 to the hinge point of the mast on the boom 12, and then connect the top section arm, the middle section and the bottom section arm in sequence. During installation, an auxiliary crane is required, and the installation cost is relatively high. And the hinge point of the door frame on the boom 12 is higher than the ground, so it is difficult to connect
