Handrail device and excavator
The invention discloses a handrail device. The handrail device comprises a first mounting plate, a second mounting plate, a first handrail pipe connected with the first mounting plate, a second handrail pipe, a third handrail pipe, and a fourth handrail pipe connected with the second mounting plate. The first handrail pipe is connected with one end of the second handrail pipe in a sleeved mode through a first energy absorption assembly, and the second handrail pipe can move in the axis direction of the pipe end connected with the first handrail pipe. The other end of the second handrail pipe is connected with one end of the third handrail pipe; the other end of the third handrail pipe is connected with the fourth handrail pipe in a sleeved mode through a third energy absorption assembly, and the third handrail pipe can move in the axis direction of the pipe end connected with the fourth handrail pipe. The invention further discloses an excavator. According to the handrail device, axialmovement in multiple directions can be achieved, the generation of internal stress is effectively reduced, and the risks of the cracking of welded joints and the cracking of connecting bolts are reduced.
本发明公开一种扶手装置，包括第一安装板、第二安装板、与第一安装板连接的第一扶手管、第二扶手管、第三扶手管和与第二安装板连接的第四扶手管；第一扶手管通过第一吸能组件与第二扶手管的一端套接，且第二扶手管能够沿与第一扶手管连接的管端的轴线方向移动；第二扶手管的另一端与第三扶手管的一端连接；第三扶手管的另一端通过第三吸能组件与第四扶手管套接，且第三扶手管能够沿与第四扶手管连接的管端的轴线方向移动。本发明还公开一种挖掘机。本发明的扶手装置能够实现多个方向的轴向移动，有效减少内应力的产生，降低焊缝处开裂及连接螺栓断裂的风险。
