The invention discloses a counterweight assembly of an automobile crane. The counterweight assembly comprises a connecting bottom plate and a counterweight block, two groups of clamping mechanisms are connected in the two moving chutes in a sliding and penetrating manner; auxiliary positioning mechanisms are arranged on two sides of the top end of the connecting bottom plate; the clamping mechanism comprises a movable sliding rod, a positioning connecting rod and a control inserting rod, a plurality of locking inserting pieces are arranged on one side of the positioning connecting rod, and a plurality of sets of positioning inserting pieces are arranged on the front face and the back face of the positioning connecting rod; the locking insertion piece comprises a locking insertion rod and two reset springs; the positioning insertion piece comprises a positioning insertion rod and two jacking springs. The two auxiliary positioning mechanisms are arranged at the top end of the connecting bottom plate and then matched with the four clamping mechanisms, in this way, positioning of the balancing weight at the top end of the connecting bottom plate is completed through the auxiliary positioning mechanisms, and then clamping work after the balancing weight is positioned is completed through the four clamping mechanisms; therefore, the weight adjustment of the whole counterweight assembly is quicker, and the adjustment of the counterweight assembly is more flexible.
本发明公开了一种汽车起重机配重组件,包括连接底板和配重块;两个移动滑槽内均滑动穿插连接由两组夹定机构,连接底板顶端的两边侧均设置有辅助定位机构;夹定机构包括移动滑杆、定位连杆和控制插杆,定位连杆的一侧设置有多个锁定插件,定位连杆的正面和背面均设置有多组定位插件;锁定插件包括锁定插杆和两个复位弹簧;定位插件包括定位插杆和两个顶撑弹簧。本发明在连接底板的顶端设置有两组辅助定位机构再搭配四组夹定机构,这样先通过辅助定位机构完成对配重块在连接底板顶端的定位,之后再利用四组夹定机构完成对配重块定位之后的夹定工作,以此就使得整个配重组件的重量调整更迅速,使得配重组件的调节更加灵活。
