Description

Technical Field

[0001] This invention relates to the field of charging tractor technology, specifically a dual-purpose (road and rail) tractor charging vehicle. Background Technology

[0002] The dual-purpose road-rail vehicle is a specialized traction vehicle capable of operating in both road and rail modes. Originally used primarily in the military, it achieves track switching via a hydraulic track-switching device and liftable guide wheels, with a switching time of approximately 10 seconds. This model uses rubber wheels for road travel and is positioned by dedicated guide wheels when traveling on rails, equipped with a real-time video monitoring system for operation assistance. Modernly, this model primarily undertakes railway maintenance, emergency rescue, and locomotive shunting tasks, and carries specialized equipment such as cranes, snow removal vehicles, and overhead contact line repair equipment. The power system is available in internal combustion engine and battery-powered versions, providing stable output and remote control operation capabilities, respectively. Some models are equipped with automatic coupler systems and all-terrain emergency functions. Operating modes are compatible with both manual driving and wireless remote control. Typical applications include overhead contact line repair vehicles, railway excavators, and integrated track inspection vehicles.

[0003] The existing road-rail dual-purpose tractor does not have DC power supply capability, which means that the tractor cannot provide power to the auxiliary tools when towing and rescuing, thus failing to meet the usage requirements. At the same time, the existing tractor lacks a rainproof cover for the charging and discharging port, which makes the charging and discharging port susceptible to being wetted by rainwater during charging and discharging. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a dual-purpose traction charging vehicle for both road and rail. By setting up an energy storage cabinet, a DC-DC converter, a charging and discharging fixing base, a discharge port and a charging port, the energy storage cabinet stores electricity when the traction vehicle is in use. After being converted by the DC-DC converter, the electricity can be discharged through the discharge port to provide power for new energy vehicles and meet the usage requirements. This can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dual-purpose road-rail traction charging car, comprising a traction car body, an energy storage cabinet disposed on the upper side of the traction car body frame, three charging gun cabinets disposed at the lower part of the energy storage cabinet, a charging and discharging fixing seat disposed between the charging gun cabinets, two charging ports disposed on the charging and discharging fixing seat, two discharging ports disposed on one side of the charging ports, a connecting cable connected to the side of the charging and discharging fixing seat away from the charging ports and the discharging ports, one end of the connecting cable connected to a DC-DC converter, a U-shaped rain cover slidably connected to the upper side of the charging and discharging fixing seat, a handle fixedly connected to the upper side of the rain cover, and support rollers installed on the inner sides of the two downward edges of the rain cover.

[0006] Furthermore, the energy storage cabinet is equipped with double doors on its side and a heat dissipation top cover on its upper side.

[0007] Furthermore, hydraulic cylinders are installed at both the front and rear ends of the tractor body, and track wheels are connected to the lower telescopic ends of the hydraulic cylinders.

[0008] Furthermore, towing hooks are fixedly installed on the front and rear end faces of the tractor body, and four wheels are installed on the underside of the frame of the tractor body.

[0009] Furthermore, a fixing lug is provided on the outer side of the DC-DC converter, and a rail is provided on the underside of the wheel.

[0010] Furthermore, the cabinet door is equipped with a pull handle with a lock body, and the cabinet door has ventilation holes.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the setting of an energy storage cabinet, a DC-DC converter, a charging and discharging mounting base, a discharge port, and a charging port, enables the energy storage cabinet to store electricity when the tractor is in use. After being converted by the DC-DC converter, the electricity can be discharged through the discharge port to provide power for new energy vehicles and meet their usage needs. 2. This invention, through the design of a rain cover and a handle, allows the rain cover to be pulled out of the vehicle body using the handle during use, thereby providing rain protection and reducing the risk of rainwater soaking the charging and discharging port.

[0020] The DC-DC converter 12 has a fixing lug 14 on its outer side and a rail 15 on the underside of the wheel 5. The DC-DC converter 12 can be fixedly installed by fixing the lug 14.

[0021] The cabinet door 7 is equipped with a handle with a lock body, and ventilation holes are provided on the cabinet door 7.

[0022] The working principle of the dual-purpose road-rail traction charging car provided by this invention is as follows: Figures 1-4 As shown, when traveling on rail 15, hydraulic cylinder 3 pushes rail wheel 4 downward, causing rail wheel 4 to press firmly onto rail 15. At the same time, the wheels 5 of the tractor body 1 rotate and move along the rail. Rail wheel 4 allows the tractor body 1 to move stably on rail 15, preventing derailment. When traveling on the road, hydraulic cylinder 3 drives telescopic structure to retract upward, maintaining a certain height difference between rail wheel 4 and the ground. Wheel 5 touches the ground and rolls, causing the tractor body 1 to move. When the tractor body 1 moves to the vicinity of the performance vehicle requiring rescue, the charging gun cabinet 16 can be opened, and then the charging gun and discharge connector can be taken out. The discharge connector is connected to the discharge port 10, and one end of the charging gun is connected to the charging port of the new energy vehicle, thereby providing charging services for the new energy vehicle and meeting actual usage needs.
