Description

Technical Field

[0001] This utility model relates to the field of dynamic compaction machines, and in particular to a composite boom head and a dynamic compaction machine. Background Technology

[0002] A boom head refers to a spatial structure that lifts heavy objects to a certain height and range. A dynamic compaction machine refers to a type of machinery used in construction engineering to compact loose soil.

[0003] With the rapid development of the national economy and the ever-expanding scale of national infrastructure construction, dynamic compaction, as a widely applicable and cost-effective foundation treatment technology, has experienced rapid development. In recent years, due to the increasing demand for improving the strength and depth of foundation treatment, the application scope of high-energy dynamic compaction technology has become wider and wider, and the performance level of dynamic compaction machines has also become higher and higher.

[0004] The main operating principle of a dynamic compaction machine is to lift the hammer to a certain height using a boom and then release it, utilizing the high impact force of the hammer to improve the foundation. Therefore, increasing the weight of the hammer and the lifting height of the hammer play a crucial role in improving the capacity and construction efficiency of the dynamic compaction machine. To meet the demands of high-capacity dynamic compaction processes, theoretically, the weight of the hammer can be increased by adding a gantry as a support structure. The gantry and the dynamic compaction machine form a three-point load-bearing structure, which can effectively improve the overall stability and reliability of the machine, thereby effectively increasing the compatible hammer weight.

[0005] Therefore, it is necessary to develop new types of composite boom heads and dynamic compaction machines to meet the requirements of high-energy dynamic compaction processes while satisfying strength and stability requirements. Utility Model Content

[0008] The composite box-shaped arm head is a forward-extending goose-head structure.

[0009] The composite box-type boom head connects the boom and gantry of the dynamic compaction machine.

[0010] The gantry is connected to the box-type arm head main board through gantry mounting holes.

[0011] The hammer lifting rope of the dynamic compaction machine is wound around the hammer lifting pulley via the hammer guide pulley.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] This utility model discloses a composite boom head, comprising a composite box-shaped boom head 1. The composite box-shaped boom head 1 includes a box-shaped boom head main plate 11, a hammer lifting pulley 12, and a hammer guide pulley 13. The hammer lifting pulley 12 is mounted on the box-shaped boom head main plate 11 through a hammer lifting pulley mounting hole 14; the hammer guide pulley 13 is mounted on the box-shaped boom head main plate 11 through a hammer guide pulley mounting hole. The composite box-shaped boom head 1 has a forward-extending gooseneck structure.

[0021] The composite box-type boom head 1 of this utility model connects the boom 2 and gantry 3 of the dynamic compaction machine. The gantry 3 is connected to the main board 11 of the box-type boom head through the gantry mounting hole 15. The hammer lifting rope of the dynamic compaction machine is wound around the hammer lifting pulley 12 via the hammer guide pulley 13. By installing the gantry 3, the dynamic compaction machine forms a three-point load-bearing structure.

[0022] This utility model is a hollow, compact box-shaped structure welded from a box-type boom head main plate 11 and various reinforcing ribs. Its shape resembles a forward-protruding gooseneck, exhibiting significant resistance to bending and torsion. It possesses advantages such as superior mechanical properties, good stability, and high reliability, perfectly suited to the construction characteristics of dynamic compaction machines. During operation, the hammer lifting rope passes through the hammer guide pulley 13 and winds onto the hammer lifting pulley 12, thus achieving the lifting action of the hammer. For example... Figure 3 As shown.

[0023] This utility model features a compact structural layout. The design places the hammer lifting pulley mounting hole 14 as close as possible to the boom centerline, allowing the hammer weight to be directly transferred to the boom 2 via the boom head main plate 11. This clear force transmission path minimizes additional bending moment and significantly improves the stress on the boom head, enhancing the lifting performance of the boom 2 and thus increasing the weight of the hammer that can be matched. Furthermore, the forward-extending gooseneck shape is highly advantageous for the height design and adjustment of the hammer lifting pulley mounting hole 14. The height of the hammer lifting pulley mounting hole 14 from the ground can be increased as needed, thereby increasing the hammer lifting height.

[0024] The boom head structure of this utility model is provided with a gantry mounting hole 15, enabling the dynamic compaction machine to have the function of mounting a gantry. By installing the gantry, the dynamic compaction machine can form a three-point load-bearing structure, such as... Figure 1 , 2 As shown, this can significantly improve the stability and reliability of the entire machine, thereby effectively increasing the weight of the matching tamping hammer.

[0025] This invention, while meeting strength and stability requirements, comprehensively increases the lifting height of the tamping hammer and provides a gantry mounting hinge point to increase the hammer's weight, thus meeting the needs of high-energy dynamic compaction processes. It offers good economic efficiency, high reliability, and significantly improves the efficiency of dynamic compaction construction, shortening the construction period.
