The invention discloses a four-position linkage operation device with an anti-skid structure for a lorry-mounted crane. The device comprises a linkage device main body and an anti-corrosion layer, wherein an oil dripping hole is formed in the upper portion of the linkage device main body, a sealing cover is mounted at the rear end of the oil dripping hole, a clamping box is arranged on the right side of the linkage device main body, a first connecting block is mounted in the clamping box, hidden grooves are formed in the front end and the rear end of the first connecting block, hidden bucklesare mounted in the hidden grooves, a connecting path valve is arranged above the first connecting block, a corrugated pipe is arranged above the connecting path valve, a handle base is arranged abovethe corrugated pipe, and an operating handle is arranged on the right side of the handle base. A full-surrounding structure is formed between the anti-skid sleeve and the handle head, so that the friction force between a palm and the handle head can be increased through the anti-skid sleeve of a corrugated structure, and therefore, the anti-skid effect is achieved, and the stability of the deviceoperated by a worker can be guaranteed.

    本发明公开了一种具有防滑结构的随车吊用四位联动操作装置,包括联动装置主体和防腐层,所述联动装置主体的上方设置有滴油孔,且滴油孔的后端安装有密封盖,所述联动装置主体的右侧设置有卡盒,且卡盒的内部安装有第一连接块,所述第一连接块的前后两端均设置有暗槽,且暗槽的内部安装有暗扣,所述第一连接块的上方设置有连接路阀,且连接路阀的上方设置有波纹管,所述波纹管的上方设置有手柄底座,且手柄底座的右侧设置有操作手柄。本发明设置有防滑套与手柄头之间构成全包围结构,这样可以通过波纹结构的防滑套增加手掌与手柄头之间的摩擦力,从而起到防滑的作用,还可以保证工作人员操作装置的稳定性。
