Movable anti-collision buffering device for road construction operation vehicle
The invention relates to a movable anti-collision buffer device for a road construction operation vehicle, which is characterized in that a buffer space is arranged between a driving component and a sliding component, an energy absorption device is arranged in the buffer space, and the energy absorption device comprises a plurality of layers of cylindrical energy absorption components which are sequentially arranged in an internally tangent manner. The outer-layer component can firstly dissipate energy in the load applying process through elastic deformation of the outer-layer component, after a collision load exceeds a critical load of the component, the outer-layer component can generate irreversible plastic deformation, and then the cylindrical energy absorption component located on the inner layer can receive extrusion so as to absorb energy and buffer. By means of the structure, multi-stage/multi-layer anti-collision buffering can be formed in a limited space, so that a good energy absorption effect is achieved, the energy absorption device of the multi-layer structure also brings good recoverability, when the outer-layer cylindrical energy absorption component is irreversibly damaged, the outer-layer cylindrical energy absorption component can be independently replaced to complete repairing of the energy absorption device, and the energy absorption device is convenient to use. And high economical performance is brought.
本发明涉及一种道路施工作业车用可移动式防撞缓冲装置，其在主动构件和滑动构件之间具有缓冲空间，缓冲空间内设置有吸能器件，吸能器件包括多层依次内切设置的筒形吸能构件，当碰撞载荷施加后，外层构件能够首先通过自身的弹性形变耗散载荷施加过程中的能量，当碰撞载荷超过构件的临界载荷后，其能够发生不可逆的塑性形变，继而使得位于内一层的筒形吸能构件能够接收挤压以进行吸能缓冲。借助于本发明的结构，在有限的空间内能够形成多级/多层防撞缓冲，从而具有较好的吸能效果，而且多层结构的吸能器件也带来了良好的回收性，当外层筒形吸能构件发生不可逆的破坏时，可单独替换即可完成吸能器件的修复，带来了很高的经济节约性。
