Description

Technical Field

[0001] The utility model relates to the field of multifunctional tool vehicles, in particular to a follow-up tool vehicle for maintenance. Background Art

[0002] When performing on-site maintenance of electric power, many tools and instruments need to be carried. Most of the existing primary maintenance tools are placed in the warehouse. When they are used, they need to be taken one by one in a tool bag, which is not easy to be complete. At the same time, the placement is messy, making the maintenance site chaotic and easy to lose or damage. The imperfect configuration and unreasonable placement of tools cause many inconveniences to power maintenance.

[0003] The existing solution is to use a maintenance tool cart that moves with the staff. However, in actual applications, due to the large size of the vehicle itself, it is often interfered with by the actual layout of the maintenance line. In particular, large and medium-sized maintenance entities at the maintenance site often need to be transported by AGV. When the AGV is operating in the maintenance line, the parking position of the maintenance vehicle may interfere with the operation of the AGV, resulting in a decrease in the efficiency of the overall maintenance line. Due to the single sensing method of the existing maintenance vehicles, it is often difficult to achieve the purpose of reasonable obstacle avoidance and interference reduction.

[0004] The patent with publication number CN216505038U discloses a multifunctional maintenance tool cart for train maintenance, which relates to the technical field of train maintenance, including a tool cart body, a tool box and a moving wheel, wherein the top of the tool cart body is fixedly connected with a tool box, and the four corners of the bottom of the tool cart body are fixedly installed with moving wheels, and a tool placement slot is arranged above the tool cart body. The utility model drives a No. 1 screw to rotate in the inner cavity of a threaded tube by a motor, and at the same time, the threaded tube drives the tool placement slot to move upward, and the threaded tube is limited by the cooperation of a limit block, a fixed plate and a limit slot, so as to avoid that when inspecting the top of the train, due to the certain gap between the tool placement slot on the tool cart and the top of the train, the staff needs to go back and forth many times to take the tools in the inner cavity of the tool placement slot, which wastes a lot of time of the staff and reduces the efficiency of train maintenance, so as to facilitate the adjustment of the height of the tool placement slot and improve the efficiency of train maintenance.

[0005] The reason why this technical solution is not interfered by the operation of AGV is mainly because it is aimed at the maintenance tool vehicle under the condition of non-disassembly maintenance of trains. This technical solution is difficult to meet the power maintenance of some large and medium-sized equipment on trains.

[0006] A maintenance follow-up tool vehicle is now needed to solve the above problems. Utility Model Content
