Description
技术领域technical field
本实用新型涉及强夯机技术领域,具体为一种具有防臂架反弹装置的强夯机。The utility model relates to the technical field of dynamic ramming machines, in particular to a dynamic ramming machine with an anti-boom rebound device.
背景技术Background technique
当前,强夯机的应用范围非常广泛,例如应用在工业与民用建筑、仓库、堆场、码头机场、路桥、人工岛、储油罐等。强夯是将夯锤吊到适当高度后使其自由落下,夯锤对地基施加强烈的冲击和振动,使地基土的结构破坏,孔隙压缩,土体局部液化,并通过裂缝排出孔隙水和气体,地基土在新的状况下固结,从而提高地基的承载能力,降低地基的压缩性;在强夯过程中,夯击能量还可以提高土层的均匀程度,减少可能出现的地基差异沉降。强夯机是实现强夯的典型施工设备,由于强夯机具有经济易行、设备简单、施工便捷、质量容易控制、适用范围广泛、施工周期短等优点,在工程应用中强夯机得到了迅速的推广。At present, the application range of dynamic compactor is very wide, such as in industrial and civil buildings, warehouses, yards, docks, airports, roads and bridges, artificial islands, oil storage tanks, etc. Dynamic compaction is to lift the rammer to an appropriate height and let it fall freely. The rammer exerts strong impact and vibration on the foundation to destroy the structure of the foundation soil, compress the pores, liquefy the soil locally, and discharge pore water and gas through the cracks. , the foundation soil is consolidated under the new condition, thereby improving the bearing capacity of the foundation and reducing the compressibility of the foundation; in the process of dynamic compaction, the tamping energy can also improve the uniformity of the soil layer and reduce possible differential settlement of the foundation. Dynamic compaction machine is a typical construction equipment for dynamic compaction. Due to the advantages of economical and easy operation, simple equipment, convenient construction, easy quality control, wide application range and short construction period, dynamic compaction machine has been widely used in engineering applications. Rapid promotion.
强夯机在施工过程中,反复不停地起吊及释放夯锤,由于夯锤是在夯机提升到一定高度突然释放的,强夯机前端的载荷突然消失,引起臂架的剧烈晃动,进而引起整机激烈晃动。臂架晃动会带来很多负面影响,降低了机手的操作舒适性,提高了动强度;待整机晃动停止后,机手才能继续操作,严重影响施工效率;整机的剧烈晃动,也严重影响到钢结构件和元器件的疲劳寿命。During the construction process of the dynamic tamping machine, the rammer is repeatedly lifted and released. Since the rammer is suddenly released when the tamping machine is lifted to a certain height, the load on the front end of the dynamic tamping machine suddenly disappears, causing the boom to shake violently, and then Cause the whole machine to vibrate violently. The shaking of the boom will bring many negative effects, which reduces the operating comfort of the operator and improves the dynamic strength; the operator can continue to operate after the shaking of the whole machine stops, which seriously affects the construction efficiency; the violent shaking of the whole machine is also serious. It affects the fatigue life of steel structures and components.
