[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, the present invention proposes a cargo transport vehicle for bridge and tunnel maintenance, including a protective top cover 1, a transport vehicle body 2 and a cargo box tail plate 3. A conveyor belt 204 is fixedly installed at the bottom inside the transport vehicle body 2, and a laser radar unit 201 is fixedly installed on one side of the transport vehicle body 2. The transport vehicle body 2 can provide installation positions for surrounding components and can provide a closed transport space for the goods to be transported. The laser radar unit 201 can scan obstacles on the vehicle's travel path in real time, thereby controlling the vehicle to autonomously avoid obstacles and move for transport.

[0025] The top of the transport vehicle body 2 is bolted with a protective top cover 1. The protective top cover 1 has a truncated pyramid structure and a material guide trough 102 is opened on the top of the protective top cover 1. The protective top cover 1 can not only effectively prevent the goods from being affected by the external environment during transportation, but also form a funnel structure by inverting it when loading and unloading goods, which further optimizes the distribution of goods. The protective cover plate 101 and the protective top cover 1 are fixed with bolts, which is convenient for disassembly and maintenance. At the same time, its truncated pyramid structure can reduce wind resistance and improve the overall stability of the vehicle during driving.

[0026] The rear panel 3 of the transport vehicle body 2, which is away from the lidar unit 201, is installed on the side of the transport vehicle body 2 via a hinge. The hinged connection between the rear panel 3 and the transport vehicle body 2 allows the rear panel to be opened and closed flexibly, facilitating loading and unloading of goods. The fan-shaped structure of the side panel 301 not only enhances the sealing of the cargo compartment, but also effectively guides the goods during loading and unloading, preventing them from slipping or being unevenly distributed. Furthermore, the interlocking connection between the side panel 301 and the interior of the transport vehicle body 2 further enhances the overall structural stability, ensuring that the goods will not loosen due to vibration or impact during transportation.

[0027] Furthermore, a protective cover plate 101 is bolted to the top of the protective cover 1 at the location of the guide chute 102.

[0028] Further, the back side of the transport vehicle body 2 is fixedly provided with an electric motor, and the output end of the electric motor penetrates the transport vehicle body 2 and is fixedly connected with the conveying belt 204. After the electric motor is powered on, the electric motor rotates to drive the conveying belt 204 to roll, so that the horizontal movement of the goods on the top of the conveying belt 204 can be realized, and the goods can be conveniently transferred and unloaded.

[0029] Further, the bottom central position of the transport vehicle body 2 is fixedly provided with a battery unit 203, and the bottom two sides of the transport vehicle body 2 are fixedly provided with drive motors. The output end of the drive motor is fixedly provided with a wheel 202, and the output end of the drive motor is connected with the bottom of the transport vehicle body 2 through a bearing. The drive motor is electrically connected with the battery unit 203 through a cable. The battery unit 203 is installed at the bottom center of the transport vehicle body 2, which not only reduces the gravity center of the vehicle, but also provides sufficient energy support for the drive motors of the two side wheels 202. The drive motor is fixedly connected with the inner side of the wheel 202, and flexible rotation is realized through a bearing, so that the vehicle can still maintain good maneuverability and stability under complex road conditions.

[0030] Further, the front and rear sides of the carriage tail plate 3 are provided with side baffles 301. The side baffles 301 are fan-shaped plates, and the side of the side baffles 301 close to the transport vehicle body 2 is hingedly connected with the inside of the transport vehicle body 2.

[0031] Working principle: In actual use, the goods transport vehicle realizes omnidirectional real-time scanning and data acquisition of the surrounding environment through the laser radar unit 201 carried thereon, realizes autonomous obstacle avoidance and flexible movement of the vehicle in combination with the intelligent control system and the wheel 202, and realizes automatic loading and unloading of goods according to actual use requirements through the conveying belt 204 built-in the goods transport vehicle. When the goods need to be loaded, the protective top cover 1 on the top is turned over and inverted to form a stable funnel-shaped structure. The goods are smoothly and uniformly distributed to the inside of the carriage through the material guide groove 102, so that the carriage space is reasonably utilized. During the whole loading and unloading process, the carriage tail plate 3 and the side baffle 301 work cooperatively to form a closed and supporting structure, so as to prevent the goods from sliding, unevenly accumulating or being damaged due to movement, vibration or other external forces.

[0032] The above specific embodiments are only several preferred embodiments of the utility model, and based on the technical scheme of the utility model and the related inspiration of the above embodiments, the person skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
