在本申请的一个实施例中,如图8所示,登高平台消防车300包括转台310和上述任一实施例中的臂架结构200。臂架结构200的第一臂架211与转台310连接。登高平台消防车300用于消防人员登高救援。In one embodiment of the present application, as shown in Fig. 8, a climbing platform fire truck 300 includes a turntable 310 and a boom structure 200 in any of the above embodiments. The first boom 211 of the boom structure 200 is connected to the turntable 310. The climbing platform fire truck 300 is used for firefighters to climb and rescue.
在本申请的一个实施例中,臂架结构200增加曲臂结构100后,从初始状态可一直保持工作斗总成250处于水平状态不会发生翻转。整个臂架结构200展开、调平分三步:In one embodiment of the present application, after the boom structure 200 is added with the crank arm structure 100, the working bucket assembly 250 can be kept in a horizontal state from the initial state without flipping. The entire boom structure 200 is unfolded and leveled in three steps:
第一步,第一臂架211在初始变幅过程中(≤45度),第二臂架212和变幅油缸(第四驱动件240)不动,主要通过曲臂110油缸(第三驱动件230)伸展和调平油缸(第一驱动件120)回缩联合控制调整,使工作斗总成250保持水平;In the first step, during the initial luffing process (≤45 degrees) of the first boom 211, the second boom 212 and the luffing cylinder (fourth driving member 240) remain stationary, and the working bucket assembly 250 is kept horizontal mainly through the combined control and adjustment of the extension of the crank arm 110 cylinder (third driving member 230) and the retraction of the leveling cylinder (first driving member 120);
第二步,当第一臂架211第二次变幅时(>45度),第二臂架212和变幅油缸也开始变幅,同时曲臂110油缸和调平油缸继续联合控制,使工作斗总成250保持水平;In the second step, when the first boom 211 changes its amplitude for the second time (>45 degrees), the second boom 212 and the amplitude changing cylinder also start to change its amplitude, and at the same time, the crank arm 110 cylinder and the leveling cylinder continue to be jointly controlled to keep the working bucket assembly 250 horizontal;
第三步,当曲臂110与第二臂架212平行时(曲臂110油缸展开最大时),通过变幅油缸和调平油缸联合控制,使工作斗总成250保持水平并达到最大高度。The third step is, when the crank arm 110 is parallel to the second boom 212 (when the crank arm 110 cylinder is fully extended), the working bucket assembly 250 is kept horizontal and reaches the maximum height through the joint control of the boom cylinder and the leveling cylinder.
当曲臂110、第二臂架212与第一臂架211平行(最大高度)时,第二云梯213与曲臂梯组件130之间存在比较大的间隙,此时通过第二驱动件134推动活动梯132在固定梯131上运动、展开,以使曲臂梯组件130与第二云梯213之间的距离缩短。固定梯131与工作斗总成250之间的间距较小,通过工作斗总成250的翻转踏板搭接
即可,从而实现工作斗总成250与曲臂梯组件130的连接,供救援人员攀爬。When the crank arm 110, the second boom 212 and the first boom 211 are parallel (maximum height), there is a relatively large gap between the second ladder 213 and the crank arm ladder assembly 130. At this time, the second driving member 134 drives the movable ladder 132 to move and unfold on the fixed ladder 131, so that the distance between the crank arm ladder assembly 130 and the second ladder 213 is shortened. The distance between the fixed ladder 131 and the working bucket assembly 250 is small, and the working bucket assembly 250 overlaps the movable ladder 132 by the flip pedal. That is, the connection between the working bucket assembly 250 and the crank arm ladder assembly 130 is realized, so that rescue personnel can climb.
根据本申请的曲臂结构、臂架结构和登高平台消防车的实施例,曲臂结构的第一驱动件用于改变曲臂与平衡臂之间的夹角,由于平衡臂与工作斗总成连接,因此控制第一驱动件能够对工作斗总成进行调平;第三驱动件用于改变曲臂与第一臂架之间的夹角,控制第三驱动件能够辅助第一驱动件对工作斗总成进行调平。臂架结构的至少两个驱动件(包括第一驱动件和第三驱动件)可以同时对工作斗总成进行调平,调平稳定性更高。另外,曲臂为臂筒结构且设有安装腔,第一驱动件放置在安装腔内,一方面可以有效避免第一驱动件与其它部件发生运动干涉,另一方面有利于提高曲臂结构收起与展开的便捷性。According to the embodiments of the crank arm structure, the boom structure and the aerial platform fire truck of the present application, the first driving member of the crank arm structure is used to change the angle between the crank arm and the balance arm. Since the balance arm is connected to the working bucket assembly, the first driving member can be controlled to level the working bucket assembly; the third driving member is used to change the angle between the crank arm and the first boom. Controlling the third driving member can assist the first driving member in leveling the working bucket assembly. At least two driving members of the boom structure (including the first driving member and the third driving member) can level the working bucket assembly at the same time, and the leveling stability is higher. In addition, the crank arm is an arm tube structure and is provided with an installation cavity. The first driving member is placed in the installation cavity. On the one hand, it can effectively avoid the first driving member from interfering with other components in motion, and on the other hand, it is conducive to improving the convenience of folding and unfolding the crank arm structure.
