Description

一种具有防臂架反弹装置的强夯机A dynamic compaction machine with an anti-boom rebound device

技术领域technical field

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.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, but should not be construed as limiting the present utility model.

下面根据本实用新型的整体结构,对其实施例进行说明。Below according to the overall structure of the utility model, its embodiment is described.

一种具有防臂架反弹装置的强夯机,如图1-4所示,包括强夯机100和配重装置180,强夯机100包括主臂110,配重装置180底端设有一组液压缸190,主臂110顶端连接有臂架120,臂架120顶端装有固定座150,且底端设有吊钩121,固定座150一侧设有连接座160,连接座160顶端设有第一缓冲油缸130,第一缓冲油缸130顶端的活塞杆132连接固定臂架120顶端,臂架120底端设有第二缓冲油缸140,第二缓冲油缸140底端侧面设有油嘴133。A dynamic tamping machine with an anti-boom rebound device, as shown in Figures 1-4, includes a dynamic tamping machine 100 and a counterweight device 180, the dynamic tamping machine 100 includes a main arm 110, and a set of Hydraulic cylinder 190, main arm 110 top is connected with arm frame 120, and arm frame 120 top is equipped with fixing seat 150, and bottom end is provided with hook 121, and fixing seat 150 side is provided with connecting seat 160, and connecting seat 160 top is provided with The first buffer oil cylinder 130, the piston rod 132 at the top of the first buffer oil cylinder 130 is connected to the top of the fixed arm frame 120, the bottom end of the arm frame 120 is provided with a second buffer oil cylinder 140, and the bottom side of the second buffer oil cylinder 140 is provided with an oil nozzle 133.

臂架120剧烈反弹时,臂架120向上回弹,先通过第一缓冲油缸130对臂架120底端产生一个拉力,使臂架120回弹速度减缓,同时臂架120顶端的第二缓冲油缸140对臂架120施加推力,进一步减缓速度,使臂架120缓慢回弹,使强夯机更加稳固,提高了动强度。When the jib 120 rebounds violently, the jib 120 rebounds upwards, and first generates a pulling force on the bottom end of the jib 120 through the first buffer cylinder 130, so that the rebound speed of the jib 120 is slowed down, and at the same time, the second buffer cylinder at the top of the jib 120 140 applies a thrust to the boom 120 to further slow down the speed, so that the boom 120 rebounds slowly, making the dynamic compaction machine more stable and improving the dynamic strength.

请着重参阅图1和图3,第一缓冲油缸130顶端与臂架120顶端由固定销151连接固定,底端由固定座150连接固定,第一缓冲油缸130内部底端设有推板131,所述推板131顶端设有弹簧134,所述弹簧134上方设有活塞杆132,所述活塞杆132有一个吻合固定销151大小的圆孔。Please refer to Fig. 1 and Fig. 3 emphatically, the top of the first buffer oil cylinder 130 is connected and fixed with the top of the boom 120 by the fixed pin 151, and the bottom end is connected and fixed by the fixed seat 150, and the inner bottom of the first buffer oil cylinder 130 is provided with a push plate 131, A spring 134 is arranged on the top of the push plate 131 , and a piston rod 132 is arranged above the spring 134 , and the piston rod 132 has a round hole matching the size of the fixing pin 151 .

减缓臂架120的反弹力度,同时加强了第一缓冲油缸130与第二缓冲油缸140对臂架120的反作用力。The rebound strength of the boom 120 is slowed down, and the reaction force of the first buffer cylinder 130 and the second buffer cylinder 140 to the boom 120 is strengthened at the same time.

请着重参阅图2,固定座150设有匹配连接座160的凹槽,且侧面设有吻合固定销151的圆孔并贯穿固定座150,固定座150安装于主臂110底端,且固定座150底端设有吻合固定销151的圆孔并贯穿。Please refer to Fig. 2 emphatically, the fixed seat 150 is provided with a groove matching the connecting seat 160, and the side is provided with a round hole matching the fixed pin 151 and passing through the fixed seat 150, the fixed seat 150 is installed at the bottom of the main arm 110, and the fixed seat The bottom end of 150 is provided with the round hole that fits with the fixed pin 151 and runs through it.

方便油缸跟随臂架120的上下摆动,同时更好的固定主臂110与臂架120上的油缸。It is convenient for the oil cylinder to follow the boom 120 to swing up and down, and at the same time better fix the main arm 110 and the oil cylinder on the boom 120 .

请着重参阅图2,油管170一端连接第一缓冲油缸130的油嘴133,一端连接至第二缓冲油缸140油嘴133。Please refer to FIG. 2 , one end of the oil pipe 170 is connected to the oil nozzle 133 of the first buffer oil cylinder 130 , and the other end is connected to the oil nozzle 133 of the second buffer oil cylinder 140 .

更好的使第一缓冲油缸130与第二缓冲油缸140同时对臂架120施加反作用力。More preferably, the first buffer cylinder 130 and the second buffer cylinder 140 apply reaction force to the boom 120 at the same time.

使用时,当吊钩121上的重物快速掉落至地面时,臂架120受惯性影响会猛烈回弹,这时第二缓冲油缸140内部的活塞杆132对臂架120施加反作用力,减缓臂架120的回弹力,同时第二缓冲油缸140内的油通过油管170流入第一缓冲油缸130时,对推板131施加推力,使第一缓冲油缸130施加向下的力,抵消臂架120向上的力,进一步减缓臂架120的回弹力,使臂架120缓慢上升,同时机身的侧面增加了配重装置180,通过液压缸190底端的吸盘牢牢的吸附住地面,有效的防止臂架120回弹导致整个强夯机100的剧烈晃动,强夯机100不但加强了强夯机100内部元件的使用寿命,更加强了施工的效率。When in use, when the heavy object on the hook 121 falls to the ground quickly, the boom 120 will rebound violently under the influence of inertia. At this time, the piston rod 132 inside the second buffer cylinder 140 exerts a reaction force on the boom 120 to slow down When the oil in the second buffer oil cylinder 140 flows into the first buffer oil cylinder 130 through the oil pipe 170, a thrust is applied to the push plate 131, so that the first buffer oil cylinder 130 applies a downward force to offset the boom 120. The upward force further slows down the rebound force of the boom 120, so that the boom 120 rises slowly. At the same time, a counterweight device 180 is added to the side of the fuselage, and the suction cup at the bottom of the hydraulic cylinder 190 firmly absorbs the ground, effectively preventing the boom from The rebound of the frame 120 causes the entire dynamic compactor 100 to shake violently. The dynamic compactor 100 not only enhances the service life of the internal components of the dynamic compactor 100, but also enhances the efficiency of construction.
