The pull rod 341 facilitates the staff to push the push plate 34 to move.

[0029] See also Figure 4 and Figure 5 A storage mechanism 4 is connected to the top of the vehicle plate 1, and the storage mechanism 4 includes a curved hollow frame 41 and a slotted hollow tube 42. The curved hollow frame 41 is convenient for limiting and storing oil drums. The curved hollow frame 41 is a curved hollow frame, and the top of the curved hollow frame 41 is provided with slots for conveniently rolling out the oil drums, and the slotted hollow tube 42 is provided with slots on the top.

[0030] The curved hollow frame 41 is connected to the vehicle plate 1, and both ends of the slotted hollow tube 42 are connected with a crankshaft shaft 43, which can support the slotted hollow tube 42. The outside of the crankshaft shaft 43 is connected with a mounting plate 44 through a bearing, and the mounting plate 44 is connected to the vehicle plate 1. The back of the slotted hollow tube 42 is connected with a servo motor 45, which can drive the slotted hollow tube 42 through the crankshaft shaft 43, and the output end of the servo motor 45 is connected to the crankshaft shaft 43. The bottom of the servo motor 45 is fixedly connected to a limiting platform 451, and the limiting platform 451 is connected to the vehicle plate 1, and the limiting platform 451 can support and limit the servo motor 45.

[0031] See also Figure 6 Both ends of the top of the vehicle plate 1 are connected to the limiting mechanism 5, the limiting mechanism 5 includes a hollow cylinder 51, the hollow cylinder 51 can be used to install the sliding frame 52, and both ends of the hollow cylinder 51 are provided with vertical grooves for facilitating the movement of the long block 54. The hollow cylinder 51 is fixedly connected to the vehicle plate 1, and the interior of the hollow cylinder 51 is slidably connected to the sliding frame 52, and the sliding frame 52 can be extended and retracted by driving the sliding frame 52 through the inclined rod 53.

[0032] The bottom of the sliding frame 52 is connected to an inclined rod 53 through a hinge, and the bottom of the inclined rod 53 is connected to a long block 54 through a hinge. The bottom of the long block 54 is slidably connected to a track block 541 through a track. The track block 541 is connected to the inner bottom of the hollow cylinder 51, and the track block 541 can make the long block 54 move linearly inside the hollow cylinder 51. The top of the sliding frame 52 is fixedly connected to a C-shaped limiting sleeve 55, and the C-shaped limiting sleeve 55 can limit the rotation of the crankshaft shaft 43 through friction. At the same time, when the staff stops pushing and pulling the push-pull mechanism 3, the push-pull mechanism 3 returns to its original position through the internal spring 33, and then drives the limiting mechanism 5 to return to its original position through the long connecting arm 6 to release the limit on the crankshaft shaft 43, and the C-shaped limiting sleeve 55 is located directly above the crankshaft shaft 43.

[0033] The bottom of the C-shaped limiting sleeve 55 is fixedly connected to the limiting ring 551, and the limiting ring 551 is a carbon fiber C-shaped block.

[0034] In this solution, the oil barrel is first placed into the curved hollow frame 41 through the top of the curved hollow frame 41, and then the push plate 34 is pushed or pulled to drive the vehicle plate 1 to move through the universal wheel 2 to transport the oil barrel. When the oil barrel needs to be discharged, the servo motor 45 is started to drive the slotted hollow tube 42 to reciprocate 90° left and right through the crankshaft shaft 43. When the slotted top of the slotted hollow tube 42 faces the outlet at the bottom of the curved hollow frame 41, the oil barrel will roll into the slotted hollow tube 42 by gravity, and the slotted hollow tube 42 will move 90° to the right. When the push plate 34 is pushed or pulled, the sliding arm 32 is driven to move, which in turn drives the long connecting arm 6 to drive the long block 54 to move, and the inclined rod 53 is pulled by the long block 54 to move left or right, and then the sliding connecting frame 52 is pulled down, so that the C-shaped limiting sleeve 55 contacts the crankshaft shaft 43, and the crankshaft shaft 43 is limited by friction. At the same time, when the car plate 1 moves, the static electricity generated by friction is automatically diverted through the added static electricity removal iron chain 7 to avoid the explosion hazard caused by static electricity through the oil barrel;

[0035] When the oil drum is being transported, the additional storage mechanism 4 can be used to quickly limit and install the oil drum to prevent the oil drum from rolling down during transportation due to its cylindrical shape. At the same time, the additional slotted hollow tube 42, crankshaft shaft 43 and servo motor 45 can be used to quickly discharge the oil drum after it is transported to the designated position to avoid the inconvenience of discharging the oil drum due to its excessive weight. At the same time, the additional long connecting arm 6 can limit the crankshaft shaft 43 when passing through the push-pull mechanism 3 to prevent the friction generated by the staff when transporting the oil drum from causing the slotted hollow tube 42 to rotate and cause the oil drum to roll down. The additional anti-static iron chain 7 can be used to divert the static electricity generated by friction when the oil drum is transported to prevent the static electricity from igniting the oil drum and causing a fire.
