Description

Technical Field

[0001] The utility model relates to the technical field of power supply equipment, in particular to a power supply vehicle. Background Art

[0002] Electric construction machinery has the advantages of low noise, zero emission, adaptability to extreme environmental conditions of high temperature, extreme cold and high altitude, low energy consumption cost, etc. However, most of the existing electric construction machinery is only used in places covered by the power network. If electric construction machinery needs to go to areas not covered by the power network, it is necessary to first evaluate the power consumption of the journey and the amount of work, otherwise the equipment will be directly "paralyzed" once the battery power is insufficient. However, because the power consumption of engineering operations is difficult to estimate, the energy replenishment problem of electric construction machinery restricts its promotion.

It can adapt to flat roads and driving conditions such as construction sites and mines. The driving speed can also be guaranteed to ensure timely energy replenishment. In addition, because the front steering drive axle rotates to connect the frame, when the road surface is slightly uneven, the front steering drive axle swings up and down, so that all four wheels can touch the ground, ensuring that the power supply vehicle can be driven reliably.

[0009] Preferably, the electric drive device is arranged at the bottom of the frame, and the electric drive device is located between the front steering drive axle and the rear drive axle. After such arrangement, there can be more space on the top surface of the frame for arranging the power battery system, and the capacity of the battery can be larger.

With this arrangement, the rotation connection of the front rotatable drive axle is simple and convenient.

[0014] Preferably, a limit block for limiting the rotation range of the front steering drive axle is provided at the bottom of the frame. The limit block limits the rotation range of the front steering drive axle to avoid oversteering and ensure steering safety.

With this arrangement, the distance between the charging interface and the battery can be extended, so that the operating range of the power supply vehicle is larger, especially when the operating environment of the electric engineering machinery to be charged is poor, such as muddy or steep slopes, the power supply vehicle can recharge the electric engineering machinery without driving to the side of the electric engineering machinery.

[0016] Preferably, the frame is provided with a first driving mechanism for driving the drum to rotate. This arrangement can facilitate the pulling of the inflation interface to the electric engineering machinery and equipment, and facilitate the storage of the cable pulled out of the drum.

After such an arrangement, the front steering drive axle 12 can swing up and down as a whole (that is, the rotating surface of the front steering drive axle 12 is a vertical surface), ensuring that the four wheels can land even when the walking road surface is uneven. A limit block for limiting the rotation range of the front steering drive axle 12 is provided at the bottom of the frame 11 to avoid oversteering and ensure steering safety. The rear drive axle 13 is directly locked to the rear end of the bottom of the frame 11 by bolts.
