Description

Technical Field

[0001] The present invention belongs to the technical field of power collection for electrified roads, and in particular relates to a stable pantograph system suitable for complex road driving environments and a design method thereof. Background Art

[0002] With the development of electrified transportation, highway electrification technology has become a research hotspot. The pantograph is a key connecting component between electrified vehicles and power supply rails, and its stability directly affects power supply efficiency and driving safety.

[0003] The existing railway pantograph system is designed based on the stable guiding relationship of "rail-train". The railway tracks are straight and flat, and the pantograph and the track can maintain stable contact.

[0004] However, in highway systems, the contact between tires and the road is affected by factors such as road surface smoothness and driver operations (such as braking, starting, and avoiding). The vehicle body is prone to ups and down bumps and left and right swaying, resulting in a significant decrease in the fit between the pantograph and the track, and even drifting, power outages and other problems.

[0005] If the railway pantograph solution is directly applied, it will be necessary to lay dedicated tracks on the highway, which will turn the highway into a tram route and face economic and technical problems such as high cost, difficulty in roadbed reconstruction, and limited cargo transportation methods. Therefore, a stable pantograph system that can adapt to the complex environment of highways is urgently needed. The purpose of the present invention is to provide a rice crust cutting device to solve the problems raised in the above background technology.

[0006] By adopting the above technical solution, the threaded sleeve on the threaded rod is protected.

[0007] Compared with the prior art, the beneficial effects of the present invention are: the rice crust cutting device, A circular cylinder, a fixing bolt and a rectangular fixing groove are provided. When the distance between the cutting blades needs to be adjusted, the fixing bolt is rotated to fix the circular cylinder, and then the threaded sleeve is rotated to move laterally on the threaded rod. The threaded sleeve and the threaded rod are threadedly connected, thereby realizing the lateral movement of the cutting blade. Then, the fixing bolt is rotated so that the through end of the fixing bolt is inserted into the rectangular fixing groove opened on the threaded rod, thereby realizing the fixation of the threaded sleeve on the circular cylinder. The cutting blade is moved laterally to realize the cutting of rice crusts of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 Schematic diagram of the overall structure of the stable pantograph system. DETAILED DESCRIPTION

[0009] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings: like Figure 1 As shown, the stable pantograph system mainly consists of a stacked pantograph transverse sliding mechanism (1), a multiple shock-absorbing support structure (2) and a displacement compensation system (3).

[0010] The stacked bow transverse sliding mechanism (1) uses a double-layer bow structure connected by a transverse slide rail, allowing the bow structure to slide transversely along the slide rail with a sliding range of 50-60 cm. When the vehicle body sways left and right due to avoidance or turning, the upper bow structure can slide along the slide rail to maintain contact between the carbon slide plate and the linear rail.

[0011] Multiple shock-absorbing support structure (2): It includes spring shock absorbers and hydraulic buffers, connected between the pantograph base and the vehicle body. When the vehicle body rises and falls due to road bumps, the spring shock absorbers absorb high-frequency small-amplitude vibrations, and the hydraulic buffers suppress low-frequency large-amplitude impacts. Together, they limit the pantograph's support force on the rail to 0.5-1.2kN, ensuring conductive stability.

[0012] Displacement Compensation System (3): Consists of a radar / infrared sensor, a controller, and an electric push rod. The radar / infrared sensor monitors the lateral offset between the vehicle body and the track in real time (e.g., 30cm offset) and transmits the signal to the controller. After calculating the compensation amount, the controller drives the electric push rod to push the pantograph base to move laterally (e.g., 30cm offset), allowing the carbon slide to re-align with the track. The system has a compensation distance of 50-60cm, which, combined with the carbon slide's own sliding range (±10cm), can achieve a single-side offset tolerance of ±40-50cm for the vehicle body.

[0013] In this embodiment, the system effectively solves the bumping and swaying problems of highway pantographs through the coordinated work of the above structures, and is suitable for electrified highway vehicles such as electric trucks.
