Because the self-unloading mechanism is arranged, the telescopic arm is telescopic, the upright post is rotatable, goods (within 3T) can be realized, the use of a travelling crane and a forklift is not occupied, and the production efficiency is greatly improved. Particularly, when the automatic cargo loading and unloading device is used, the rear driving mechanism provides power, the vehicle body moves to a target cargo loading area, the stand column is rotated manually, the cross arm and the telescopic rod are adjusted to move cargos to be moved, the lifting of the cross arm is controlled to adjust the height, the length of the telescopic rod extending out of the cross arm is controlled to control the length, the cargos are suspended at the end part of the telescopic rod, the cross arm is controlled to rise, and the stand column is rotated to place cargos on the vehicle body, so that the cargos can be automatically loaded and unloaded.

In some embodiments of the present invention, the steering mechanism 4 is a set of driven wheels (i.e. acting as driven wheels, which can rotate with the operation of driving wheels in the rear-wheel dual-four-wheel drive structure) mounted at the bottom of the vehicle body through a front axle assembly. More specifically, the front axle of the front axle assembly is fixedly connected to the vehicle body bottom through a front support. The structure can realize the steering of the vehicle body when the rear driving mechanism provides power.

In some embodiments of the present invention, the rear driving mechanism 5 adopts a rear wheel dual four-wheel drive structure; the double four-wheel-drive structure of the rear wheel comprises two groups of driving wheels 501 arranged in parallel, and a rotating shaft of each group of driving wheels 501 is connected with a motor 503 through a speed reducer 502, so that the load of the motor can be reduced, and the power can be increased. More specifically, as shown in fig. 7, each set of driving wheels includes two driving wheels 501 and a rotating shaft 504, the two driving wheels 501 are fixed at two ends of the rotating shaft 504, portions of the rotating shaft 504 located inside the two driving wheels 501 are connected to a driving device frame 505 through bearings, and the top of the driving device frame 505 is fixedly mounted (welded or bolted) on the lower surface of the bottom of the vehicle body 2. The rotating shaft 504 is provided with a speed reducer 502, the input end of the speed reducer 502 is connected with the output end of the motor 503, the motor 503 is installed on the motor base 506, two sides of the motor base 506 are respectively and fixedly connected (can be connected through bolts) with a base connecting rod 507, the tops of the two base connecting rods 507 are respectively and fixedly connected with a fixed connecting plate 508 in a threaded mode, and the two fixed connecting plates 508 are fixedly installed (can be welded or connected through bolts) on the inner wall of the driving device frame 505, so that the motor 503 is fixedly installed.

Further, in order to reduce the vibration of the vehicle body to the motor during traveling, shock absorbing pads 509 are mounted at the joints of the base connecting rods 507 and the fixed connecting plates 508 and the joints of the base connecting rods 507 and the motor base 506.

In some embodiments of the present invention, a cab 2 is further disposed on the vehicle body 1; preferably, in order to increase the utilization rate of the platform body, the cab 2 is provided on the left side of the body 1. Meanwhile, in order to ensure as much space as possible in the vehicle body, the cab 2 is preferably provided at an end of the vehicle body 2 on a side of the dump body 3 and the steering mechanism 4 remote from the rear drive mechanism 5.

In some embodiments of the present invention, in order to conveniently provide power for the rear drive mechanism and the dump truck mechanism, a battery 6 is further mounted at the bottom of the vehicle body 1, and the battery 6 is located between the steering mechanism 4 and the rear drive mechanism 5. The flat electric locomotive disclosed by the invention is powered by the storage battery, has an ultra-large endurance, and is energy-saving and environment-friendly.

In some embodiments of the present invention, the pillar 301 is mounted on the top of the vehicle body 1 via a steering seat 304 and a base 305. Specifically, the bottom of the base 305 may be fixedly mounted on the top of the vehicle body 2 by a bolt connection, the upper end of the base is rotatably connected (via a bearing) to a steering base (the steering base is an existing commercially available mechanical component), and the top of the steering base 304 is detachably and fixedly connected (e.g., bolted) to the bottom of the pillar 301. When the telescopic arm is used, the upright post is manually rotated, so that the cross arm and the telescopic arm can be driven to rotate.

In some embodiments of the invention, for the purpose of moving the cross arm up and down away from the end of the upright, the cross arm 302 is hinged at the top of the upright 301, as shown in fig. 8. Meanwhile, a first upright cylinder 306 is mounted on the upright 301 on the side close to the rear driving mechanism 5, and a plunger of the first upright cylinder 306 is fixedly connected with the lower surface of the cross arm 302. Therefore, the first upright cylinder not only can fix the relative position of the cross arm and the upright to avoid the falling of the cross arm, but also can realize the purpose that the cross arm and the telescopic rod on the cross arm move upwards and downwards while the movable column of the first upright cylinder stretches out and draws back, namely the purpose that one end of the cross arm, far away from the upright, moves upwards and downwards.

In some embodiments of the invention, as shown in fig. 8, the telescopic arm 303 is slidably connected to the cross arm 302 at the end near the rear drive mechanism 5 in order to move the telescopic arm in the direction of the length of the cross arm towards and away from the column. Meanwhile, in order to fix the cross arm and the telescopic arm, a second upright cylinder 307 is further mounted on the surface of the cross arm 302, and a movable column of the second upright cylinder 307 is fixedly connected (in a bolt connection mode or the like) with a part of the telescopic arm 303 extending out of the cross arm 302. Thus, the extension and contraction of the telescopic arm can be realized. It should be noted here that as shown in fig. 1-6, the telescopic arm 303 can be slidably connected to the cross arm 302 in various ways: the first mode can be adopted, wherein the cross arm is of a hollow tubular structure, preferably a hollow square tube structure, the telescopic arm is inserted into a square tube from the end part of one end, away from the upright post, of the cross arm, and then the telescopic arm and the square tube are connected in a sliding manner (the sliding connection mode can be sliding connection through a smooth surface, sliding connection through a slide rail or sliding connection through a dovetail groove dovetail block); the mode II can also be adopted, the cross arm adopts a hollow square tube structure, and the telescopic arm is connected on the lower surface of the cross arm in a sliding way (the sliding connection mode can be sliding connection through a sliding rail, and can also be sliding connection through a dovetail groove dovetail block); the mode III can also be adopted, namely the cross arm adopts a solid structure, and the other modes are the same as the mode II, and the like. In contrast, since the cross arm has a hollow structure, the weight of the cross arm can be reduced, and the length of the telescopic arm can be extended as much as possible by inserting the telescopic arm into the hollow portion of the cross arm, and therefore, the first embodiment is preferable in practical use.

Preferably, the first and second upright cylinders 306 and 307 are hydraulic cylinders. The first column cylinder 306 and the second column cylinder 307 are each electrically connected to a hydraulic control system (the hydraulic control system is conventional and may be mounted on the bottom of the vehicle body) mounted on the vehicle body or on the column 301. It should be noted that, in theory, the first column cylinder and the second column cylinder may also adopt an air cylinder or an electric cylinder, but in practice, the air cylinder is not feasible because the air cylinder needs an air compressor to supply air, and therefore, the power consumption is large, the stability is high, and the pressure is insufficient; and the electric cylinder has too large power consumption, insufficient lifting force and instability. Therefore, the first column cylinder 306 and the second column cylinder 307 are preferably hydraulic cylinders, and when the hydraulic cylinder is used, the hydraulic cylinder is controlled by a hydraulic system arranged on the vehicle body, so that the power consumption is low, the pressure is high, the lifting force is high, and the operation is stable.

Preferably, the cross arm 302 of the present invention has an arm length of up to 3 meters.

In some embodiments of the invention, the body is flat, as shown in fig. 2-6, while in other embodiments of the invention, the body may also be of a frame construction, as shown in particular in fig. 1, for weight reduction.

In some embodiments of the invention, the number of hooks may be set as desired, such as 1, 2 or more.

In some embodiments of the invention, a steering wheel, a seat and a speed governor are mounted in the cab, and the speed governor may function as a throttle.
