The invention belongs to the technical field of engineering machinery, and particularly relates to a balance weight locking device and a crawler crane, the balance weight locking device comprises a balance weight body, a balance weight lock rod and a positioning lock, the balance weight body comprises a bottom balance weight and a plurality of balance weights stacked on the bottom balance weight, and a plurality of positioning lifting lugs are arranged at the tops of the bottom balance weight and the balance weights; positioning grooves matched with the vertically adjacent positioning lifting lugs are formed in the bottom of the balancing weight; the counterweight lock rod vertically extends upwards from the bottom of the bottom counterweight and penetrates through the plurality of counterweight blocks, and the bottom end of the counterweight lock rod is detachably connected with the bottom counterweight; and the positioning lock is mounted on the counterweight lock rod in a height-adjustable manner so as to lock the vertical movement of the counterweight block. According to the locking device, the position of the balancing weight is locked through the positioning lock with the adjustable mounting height, the technical problem that an existing locking device can only lock the balancing weight with the fixed layer number is solved, when a client selects to use a graded load, the balancing weight can still be locked, and the complex working requirement of the crawler crane is met.

    本发明属于工程机械技术领域,具体涉及一种配重锁定装置及履带起重机,配重锁定装置包括配重本体、配重锁杆和定位锁,配重本体包括底配重和层叠在底配重上的多个配重块,底配重和配重块的顶部设有多个定位吊耳,配重块的底部设有与上下相邻的定位吊耳适配的定位凹槽;配重锁杆从底配重的底部垂直向上伸出并贯穿多个配重块,配重锁杆的底端与底配重可拆卸连接;定位锁可调节高度地安装于配重锁杆上以锁止配重块的竖向移动。本发明通过可调节安装高度的定位锁对配重块进行位置锁定,解决了现有锁定装置只能针对固定层数的配重进行锁定的技术问题,当客户选择使用分级载荷时,仍然能够对配重进行锁定,满足了履带起重机复杂的工作要求。
