Abstract
Description
Technical Field
[0001] This invention relates to the field of road construction technology, and more specifically to an intelligent transport vehicle for electricity. Background Technology
[0002] Due to the presence of tunnels, green spaces, equipment bases, and other confined spaces within existing substations, ordinary wheeled transport vehicles cannot pass smoothly within the station, which in turn affects the transportation of work materials—especially heavier materials such as porcelain insulators, circuit breakers, and disconnect switches. Therefore, there is an urgent need for an all-terrain intelligent handling vehicle that can be adapted to various working conditions within the station to ensure the safe and convenient delivery of materials.
[0003] An existing patent describes an all-terrain transport vehicle (CN219361193U) capable of real-time leveling. By incorporating track links, track supports, link supports, leveling pitch cylinders, and two leveling yaw cylinders (left and right), this transport vehicle can perform dual leveling in both the X-axis and Y-axis directions. Simultaneously, it performs real-time leveling during movement. By adjusting the angle between the walking mechanism and the vehicle body, it adapts to the slope of the vehicle along the X and Y axes, significantly improving stability during travel. The angle between the vehicle body and the link is adjusted by extending and retracting the leveling pitch cylinders. When the piston rod of the cylinder extends, the link remains stationary, and the rear of the upper part of the vehicle body begins to tilt, forming an angle with the track's direction of travel to adjust stability. When the piston rod of the cylinder returns... When retracting, the rear of the upper vehicle body tilts downwards, allowing the transport trolley to travel stably on slopes. The retraction of the two leveling and swaying cylinders on the left and right drives the connecting rods to extend and retract, changing the spatial position of the tracks to adapt to different slopes along the X-axis. However, leveling the sides of the vehicle requires adjusting the spacing between the track travel components on both sides. Since outdoor terrain is fixed and inconvenient, this transport trolley has significant limitations in use. It cannot perform real-time leveling on narrow roads or slopes, and the leveling process greatly increases the friction of the track travel components, easily causing damage and significantly increasing costs. Therefore, designing an electric intelligent transport trolley to solve these problems is particularly important. Summary of the Invention
[0004] To address the aforementioned problems, this invention presents an intelligent transport vehicle for electric applications. The designed X-axis adjustment component does not alter the spacing between the two tracked walking mechanisms during operation.
