They are specially made or specially modified, equipped with fixed devices and equipment, and their main function is not to carry people or goods. The emergency power supply vehicle is a type of special vehicle. Emergency power supply vehicle: a special vehicle equipped with a power supply device, which can be equipped with a battery pack, a diesel generator set, a gas generator set, etc., and can realize functions such as power generation, equipment maintenance, conference support, and field operations. The special carriage of the emergency power supply vehicle is the emergency power supply carriage. However, when the prior art is used, the carriage is simply equipped with power supply equipment. When there are multiple points that need to be powered at the emergency power supply location and the power supply points are far apart, the power supply equipment can only be parked at the middle power supply point as much as possible, and then the power supply line is extended to each point for power supply, resulting in long wiring lines, increased power supply losses and costs, and more likely to cause power supply dangers. Although multiple power supply devices can be equipped for power supply, it also means that two different emergency vehicles need to be prepared, which is costly, and multiple power supply devices need to be manually lifted to the power supply point for use, which is inconvenient.

A skateboard assembly groove 3d is provided on the top of the main board body 3g, a screw 3i is fixed in the skateboard assembly groove 3d, the lifting skateboard 3h is covered and assembled on the screw 3i, the lifting skateboard 3h is arranged in the skateboard assembly groove 3d, a second gear 3f is penetrated and assembled on one side of the lifting skateboard 3h, the second gear 3f is also covered and assembled on the screw 3i and is threadedly connected with the screw 3i, the second gear 3f, the motor cover 3b and the motor 3e are fixedly assembled on the top of the lifting skateboard 3h, the motor 3e is equipped with a first gear 3c, and the motor 3e drives the second gear 3f to rotate through the first gear 3c, and a protective plate 3a is also fixed on the top of the main board body 3g, and the protective plate 3a is used for protecting the lifting equipment assembled on the lifting skateboard 3h.

[0033] Implementation plan: During the use of the equipment, the power supply line for the main power supply can be installed in the main line storage slot 2c, and the power supply equipment and the power supply line for the separate power supply can be installed in the power supply assembly slot 2f4 and the auxiliary line storage slot 2f5 of the power supply trolley 2f respectively. At the same time, the hook lock lifting equipment is installed on the lifting slide plate 3h within the range of the protective plate 3a. When in use, if it is used as a mother carriage, when the power supply trolley 2f is stored, the auxiliary power supply line can be connected to the branching connector 2k on the wire rack 2e in the corresponding sub-box slot 2d. The power supply trolley 2f on the same layer can be connected in parallel to supply power from the main line of the main line storage slot 2c. When there are multiple long-distance power supply points, the second door panel 21 can be opened, and then the hook of the hook-lock lifting device is hooked to the lifting ring 2f1 on the outer side of the car of the power supply trolley 2f, and then the power supply trolley 2f is dragged to slide out through the pad 2h1 and the shaft 2h2 in the slide groove 2h4 of the assembly plate 2h3, and then the hook of the hook-lock lifting device is hooked to the lifting ring 2f on the inner side of the car of the power supply trolley 2f. The power supply trolley 2f is lifted by the lifting ring 2f1, and then the pad 2h1 is pushed back to the power supply trolley 2f, and then the power supply trolley 2f is lowered by the hook and lock lifting equipment. At this time, the power supply trolley 2f is supported by the moving wheels 2f3, which is convenient for moving to the power supply point. When the power supply is separated, the power supply trolley 2f can be lifted by the hook and lock lifting equipment, and then the pad 2h1 is dragged out and the power supply trolley 2f is lifted and placed on the pad 2h1, and then the power supply trolley 2f is pushed into the sub-box slot 2d. When pushing it in, if there is a position deviation, the first anti-collision bar 2g gradually The added structure can facilitate the calibration of the position of the power supply trolley 2f. At the same time, the power supply trolley 2f is supported by the pad 2h1 instead of the moving wheel 2f3, so as to avoid random movement during transportation. The setting of the first anti-collision strip 2g and the second anti-collision strip 2m can also better limit the position of the power supply trolley 2f to prevent it from bumping into the carriage during transportation. The setting of the independent storage slot can also better avoid the damage of equipment in other carriages caused by the failure of some equipment, so that the equipment is free from the inconvenience of long power supply lines, and at the same time, it is free from the need to equip a variety of power supply vehicles, which is convenient for use.

[0034] At the same time, when lifting the power supply trolley 2f of the sub-box slot 2d in different positions, the lifting slide 3h equipped with the hook lock lifting equipment can be moved by controlling the motor 3e. The motor 3e drives the second gear 3f to rotate through the first gear 3c. Since the position of the second gear 3f is limited by the lifting slide 3h, it can only rotate at the fixed position of the lifting slide 3h, and the lifting slide 3h is limited to the slide assembly slot 3d and cannot rotate, and the screw rod 3i threadedly connected in the middle part of the second gear 3f cannot rotate, so that the second gear 3f will move with the thread direction when rotating, thereby driving the lifting slide 3h to move in the slide assembly slot 3d, so as to facilitate the adjustment of the lifting position.

[0035] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
