Description

Technical Field

[0001] The present invention relates to the technical field of mine transport vehicles, and particularly to an explosion-proof lithium battery remote control mine transporter. Background Art

[0002] In the prior art, most mine transporters are driven by diesel engines. Because of their powerful torque output, they can easily cope with complex floor conditions underground when fully loaded with heavy objects, ensuring efficient and stable material transportation. However, a large amount of exhaust gas generated during the operation of diesel engines, including pollutants such as particulate matter and nitrogen oxides, will seriously affect the air quality underground and threaten the health of miners. At the same time, the high cost of diesel continues to rise with the fluctuation of oil prices, and the equipment maintenance requires professional technology and high costs, greatly increasing the operating costs of enterprises. The Chinese utility model patent with the publication number CN214989832U adopts this structure. In addition, a new energy mine crawler transporter disclosed in the Chinese utility model patent with the publication number CN218536919U of the Chinese patent uses a charging and discharging power source as the energy source of the transporter and outputs power through a motor. Compared with the traditional diesel engine as the power source, the noise is relatively small, there is no exhaust gas pollution, energy is saved and emissions are reduced, and it is safe and environmentally friendly; compared with the traditional motor with an external power source, there is no need to drag a cable. However, due to the short working endurance time of the battery, it needs to be charged frequently, and each charging time is relatively long, resulting in low work efficiency.

[0039] Embodiment 2

[0040] As Figure 8 shown, the rest is the same as Embodiment 1, and the differences are as follows:

[0041] A mine explosion-proof lithium battery remote control carrier vehicle further includes a heat dissipation structure for cooling the motor 184. The heat dissipation structure includes a water tank 13 and a water pump 25; the water tank 13 is located at the bottom of the carrier vehicle and is fixedly connected to the vehicle frame 1 by bolts; the motor 184 is a water-cooled motor with a water-cooling channel inside. The water tank 13 is connected to the water-cooling channel inside the motor 184 through an external pipeline, and the water pump 25 is arranged on the external pipeline and is fixedly connected to the vehicle frame 1.

[0042] The basic working principle of a mine explosion-proof lithium battery remote control carrier vehicle is as follows: After the operator presses the explosion-proof start button, the lithium battery 15 starts to supply power to the motor controller 19 and the control box 20. The lithium battery 15 with a voltage of 320V is boosted by the motor controller 19 to stably supply power to the motor 184 with a working voltage of 380V. After the motor 184 is powered on, it rotates and drives the plunger pump 181 to operate through the coupling 183 and the bell housing 182, thereby driving the hydraulic system to work. The plunger pump 181 extracts hydraulic oil from the fuel tank 23, filters it through a filter, and is finally controlled by the multi-way valve 21 and returns to the fuel tank 23, forming an open hydraulic circuit. By manually or remotely operating the multi-way valve lever 22 on the multi-way valve 21, the switching of each directional valve in the multi-way valve 21 can be realized, and the on-off of the corresponding oil circuit can be controlled, thereby realizing functions such as the vehicle's traveling, hoisting, and the retraction and extension of the outriggers 10. At the same time, the control box 20 controls the water pump 25 to work, extracts coolant from the water tank 13, and flows into the water-cooling channels inside the motor controller 19 and the motor 184 through an external pipeline, completing the effective heat dissipation of the power system.
