[0022] The walking support mechanism 1 includes a track 11 and a car body 12. The track 11 is a double-track 11 structure. The track 11 is arranged along the chain line between the charging rack 5 and the downstream conveying chain line 6; the front and rear ends of the car body 12 are both composed of four columns, a base plate and walking wheels arranged at the four corners of the base plate. The front and rear frames are connected by a crossbeam to form a frame structure car body 12; the two ends of the conveying roller machine 2 are respectively connected to the feed end lifting mechanism 3 and the unloading mechanism 4; the feed end lifting mechanism 3 is arranged at the rear end of the car body 12, and the unloading mechanism 4 is arranged at the front end of the car body 12.

[0023] The skeleton on both sides of the roller of the conveying roller machine 2 is set as a three-section articulated connection structure. The corresponding three-section skeleton also divides the roller line of the conveying roller machine 2 into three sections. The first hinge shaft 21 is set at the hinge on both sides of the first section skeleton and the second section skeleton, and the second hinge shaft 22 is set at the hinge on both sides of the second section skeleton and the third section skeleton. The second hinge shaft 22 is hinged to the two columns on the rear side of the front end frame respectively to place the third section roller line 25 in the front end frame of the vehicle body 12. The height position of the second hinge shaft 22 matches the height position of the downstream conveying chain plate line 6.

[0024] The feeding end lifting mechanism 3 includes a guide rail 31, a first electric cylinder 32, a hanger 33 and a second electric cylinder 34; the guide rails 31 are respectively arranged on the two columns on the front side of the rear end frame; the first electric cylinder 32 is vertically arranged on the rear end of the cross beam of the vehicle body 12, and the piston rod of the first electric cylinder 32 is connected to the top of the hanger 33. The hanger 33 is a square structure with four arms. The width of the hanger 33 matches the width of the conveyor roller 2. The lower ends of the two arms at the front end of the hanger 33 are respectively connected to the first hinge shafts 21 of the skeletons on both sides of the conveyor roller 2. Sliders 331 that cooperate with the guide rail 31 are provided on the two arms at the rear end of the hanger 33. A bracket is provided on the middle part of the rear end of the hanger 33. The second electric cylinder 34 is hinged on the bracket. The piston rod of the second electric cylinder 34 is hingedly connected to the middle part of the roller skeleton at the rear end of the first section roller line 23 through a universal joint.

[0025] The unloading mechanism includes a cylinder 41, a mounting frame 42, a third electric cylinder 43, a slide rod 44 and a unloading scraper 45; the cylinder 41 is hingedly mounted on the bottom plate at the front end of the vehicle body 12, and the piston rod of the cylinder 41 is hingedly connected to the lower middle side of the front end frame of the third section roller line 25. The mounting frame 42 is arranged on the upper part of the front end frame, and the mounting plates of the mounting frame 42 are relatively arranged on both sides of the width direction of the vehicle body 12. The third electric cylinder 43 is horizontally arranged on the mounting plate close to the side of the chain plate line, and the four slide rods 44 are respectively arranged between the two mounting plates. The upper end of the unloading scraper 45 is passed through the four slide rods 44 and is connected to the piston rod of the third electric cylinder 43. The lower end of the unloading scraper corresponds to the position of the battery tray on the conveyor roller machine.

[0026] The working process of this utility model is: Figure 1Taking a row of three-layer charging racks as an example, when charging is completed, the external control system controls the operation of the vehicle body 12 and the conveying roller machine 2. The vehicle body 12 moves to the position corresponding to the first section roller line 23 and the first row of charging water tanks and stops. The first electric cylinder 32 works to adjust the position of the hanger 33 to the height of the uppermost charging water tank of the charging rack 5. The second electric cylinder 34 works, and the piston rod extends downward to lower the rear end of the first section roller line 23. The front end of the first section roller line 23 rotates around the first hinge shaft 21. When the first section roller line 23 is in a horizontal position, the second electric cylinder 34 stops. At this time, the first section roller line 23 corresponds to the position of the charging water tank of the charging rack 5. The batteries and pallets 7 in the charging water tank are manually pushed onto the first section roller line 23. The roller of the conveying roller machine 2 rolls to drive the pallets and batteries forward. At the same time, the piston rod of the second electric cylinder 34 returns, pulling the first section roller line 23 back to the same inclination angle of the second section roller line 24, so that the pallet can smoothly enter the second section roller line 24 from the first section roller line 23. When the battery and the pallet 7 move to the third section roller line 25, the piston rod of the cylinder 41 extends to lift the front end of the third section roller line 25, and the third section roller line 25 rotates around the second hinge shaft 22. When the third section roller line 25 is in a horizontal position, the cylinder 41 stops, and the piston rod of the third electric cylinder 43 returns, driving the unloading scraper 45 to move along the slide bar 44 toward the chain plate line. The unloading scraper 45 transfers the pallet from the third section roller line 25 to the chain plate line, completing a unloading process. When the pallet is removed from the third section roller line 25, the unloading process is completed. During the process of moving from one section of the roller line 23 to the second section of the roller line 24, the vehicle body 12 moves forward to the next row position of the charging rack 5. When the pallet leaves the first section of the roller line 23, the second electric cylinder 34 repeatedly pushes the first section of the roller line 23 to a horizontal position to welcome the next pallet to enter, thereby forming a continuous unloading operation; when all unloading operations on this layer are completed, the position of the hanger 33 is adjusted by the first electric cylinder 32 to match the position of the charging rack 5 on the next layer, and then the above process is followed until all unloading operations are completed.

[0027] The driving mechanism of the walking trolley and the connection between the power mechanism of the conveying roller machine and the external control system of the utility model are all existing technologies, so they are not described in detail.

[0028] The parts not described in detail in this utility model are prior art.

[0029] The embodiments selected herein for the purpose of disclosing the present invention are currently considered appropriate, but it should be understood that the present invention is intended to include all changes and improvements of the embodiments that fall within the scope of the present concept and invention.
