Dynamic compaction machine and arm rack device thereof

Abstract

The invention discloses an arm rack device of a dynamic compaction machine. The arm rack device comprises a supporting arm rack (6), the bottom of which is connected with the body of the dynamic compaction machine; the arm rack device also comprises a front stretching arm head device (1) arranged at the top of the supporting arm rack (6), and a fixed pulley (2) for lifting a rammer (7) of the dynamic compaction machine is arranged at the front end of the front stretching arm head device (1); the rammer (7) is relatively far from the supporting arm rack (6), so the operating space of the rammer (7) in the horizontal direction is enlarged, movement interference between the rammer (7) and the supporting arm rack (6) is avoided, and the operating safety is increased; and the rammer (7) of the same diameter can be lifted to a greater height, so that the operating performance of the dynamic compaction machine is fully exerted, and the work efficiency of the dynamic compaction machine is improved. Moreover, the invention also provides the dynamic compaction machine comprising the arm rack device.

Description

technical field [0001] The invention relates to the technical field of dynamic ramming machines, in particular to an arm support device of a dynamic ramming machine. In addition, the present invention also relates to a dynamic compaction machine comprising the above-mentioned boom device. Background technique [0002] The dynamic tamping machine is a mechanical equipment used for ground and foundation compaction in engineering construction. It mainly uses the strong impact force generated by the falling of the rammer to improve the strength of the foundation, anti-seismic ability, and eliminate the collapsibility of the ground. [0003] Please refer to the attached figure 1 , figure 1 It is a structural schematic diagram of a typical dynamic compaction machine in the prior art. [0004] The structure of a typical dynamic compaction machine in the prior art mainly includes a control system, a lifting mechanism, and compacting equipment connected with the lifting mechanism,...

Problems solved by technology

[0007] Please refer again figure 1 In the prior art, the fixed pulley 6' connected to the rammer 4' is directly installed on the upper section arm 1', so that the horizontal distance between the installed rammer 4' and the support arm is relatively short, and the rammer 4' is in the It is easy to interfere with the movement of the support arm during the ascent process, and the space under the arm is not easy to be fully utilized, especially when the diameter of the rammer 4' is relatively large (about 2.2 to 3.0m), in order to avoid the rammer 4' collided with the supporting arm frame, the lifting height of the rammer 4' dropped significantly, which reduced the effective working height of the rammer 4', and the corresponding working efficiency of the dynamic compaction machine was relatively low
