The crane comprises a cargo boom, a bearing base, a bearing butt joint mechanism, a clamping limiting piece, a sensor assembly, a pressure sensing mechanism and a plug pin, when a sensor body needs to be maintained and replaced, the plug pin is pulled out, the pressure sensing mechanism is lifted, the sensor assembly on the clamping limiting piece is taken down, and the sensor assembly on the clamping limiting piece is taken down; the sensor main body can be replaced and maintained by replacing a new sensor assembly and inserting the bolt back, the maintenance and replacement work of the sensor main body is facilitated, the bolt is pulled out, the pressure sensing mechanism, the sensor assembly and the clamping limiting piece on the bearing butt joint mechanism are sequentially taken down, and when the clamping limiting piece is detached, the sensor main body can be replaced and maintained. The driving block is pushed by the spring to drive the butt joint block to be separated from the butt joint hole to move towards the interior of the mounting groove, the bearing butt joint mechanism can be integrally pulled out of the rotary frame through the handle, and the clamping limiting piece, the sensor assembly and the pressure sensing mechanism can be conveniently disassembled and assembled from the rotary frame through the bearing butt joint mechanism.
本发明公开了一种具有起重量限制器的起重机,包括起重臂、轴承底座、承托对接机构、卡接限位件、传感器组件、压力传感机构以及插销,在需要对传感器主体进行维护更换时,拔出插销并抬起压力传感机构,取下卡接限位件上的传感器组件,换上新的传感器组件并插回插销即可实现传感器主体的更换维护,便于传感器主体的维护更换工作,拔出插销并依次取下承托对接机构上的压力传感机构、传感器组件以及卡接限位件,在拆下卡接限位件的同时,驱动块在弹簧的推动下带动对接块脱离对接孔向着安装槽内运动,通过把手可将承托对接机构整体拉出回转框架,通过设置承托对接机构便于卡接限位件、传感器组件以及压力传感机构与回转框架之间的拆装。
