Description

Technical Field

[0001] The utility model relates to the technical field of large train maintenance, and particularly relates to a large vehicle maintenance vehicle equipped with a robotic arm. Background Art

[0002] The daily maintenance of large trains such as trains and subways is mostly carried out in the tunnels under the tracks, and the tunnel maintenance vehicle is an engineering vehicle specially designed for maintenance and repair operations in tunnels, mines or other underground tunnels.

[0003] The Chinese patent authorization announcement number is CN221116907U, and the name is a movable operation platform for subway train maintenance tunnels, including a movable base and a lifting platform arranged on the movable base. The lifting platform includes an outer frame and an inner frame. The outer frame is fixed on the movable base, and a sliding installation groove for accommodating the inner frame and supporting the inner frame to slide in the vertical direction is arranged in the outer frame. The inner frame is arranged in the sliding installation groove; a first ear seat is arranged on the inner frame, a second ear seat is arranged on the outer frame, the operation platform further includes a connecting rod and an L-shaped operation rod. One end of the connecting rod is rotatably connected to the first ear seat, the other end is rotatably connected to the short arm end of the L-shaped operation rod, and the corner of the L-shaped operation rod is rotatably connected to the second ear seat. Through the design of the inner frame and the outer frame, combined with the three-rotating shaft design of the connecting rod and the L-shaped operation rod, the lifting and lowering of the inner frame can be easily realized by using the L-shaped operation rod, and the operation is convenient, indirectly improving the work efficiency.

[0004] The deficiencies of the above-mentioned prior art solutions are as follows: Although the above solution can lift and lower the inner frame by using the L-shaped operation rod, however, its functions are relatively concentrated, mainly limited to vertical handling tasks. At the maintenance site, if the staff faces diverse operation requirements, they may need to carry additional tools to cope with different situations. Due to the limited space in the tunnel, carrying more tools will undoubtedly further compress the operation range of the staff, which not only increases the operation difficulty, but also may affect the maintenance efficiency and safety.
