[0002] With the development of society, electric energy, as the main energy source in daily life, is becoming increasingly important. In addition to traditional thermal power generation, wind power generation, solar power generation, hydraulic power generation, nuclear power generation, etc., how to improve the effective utilization rate of electric energy is also a very important research topic. Especially in the context of increasingly strict carbon emissions, zero-carbon electric energy plants have emerged. When the power consumption in society is at a low ebb, the redundant electric energy is stored in the plant, and when the power consumption in society is at a peak, the electric energy is fed into the grid to relieve the burden on the national power grid. This measure is an effective supplement to the national power system. Therefore, zero-carbon electric energy plants are generally built near prosperous big cities or large industrial areas. Therefore, setting more electric energy storage devices (battery packs) in a limited space directly affects the efficiency and effectiveness of the plant. Therefore, when arranging battery packs in the plant area of a zero-carbon electric energy plant, there are problems in the replacement, maintenance, and transfer of battery packs.

[0026] The following will further describe the present utility model with reference to the appended Figure 1 to the appended Figure 6 drawings.

[0027] A battery pack transfer device in a narrow roadway space of an energy storage power plant, comprising: a vehicle chassis 3, located in the roadway between every two adjacent shelves 1, and wheels are respectively installed at the four corners at the lower end of the vehicle chassis 3; a guide rod 6, vertically installed on the vehicle chassis 3, and a lifting slide seat 5 is slidably sleeved on the upper end of the guide rod 6 along the vertical direction; a slide seat driving mechanism, arranged on the vehicle chassis 3, for driving the lifting slide seat 5 to slide up and down along the guide rod 6; a support arm 12, installed at the upper end of the lifting slide seat 5; an I-beam 8, arranged horizontally, and the I-beam 8 is installed on the support arm 12 through a slewing mechanism, and an electric hoist 10 is slidably installed at the lower end of the I-beam 8; when the slewing mechanism drives the I-beam 8 to rotate to be arranged in the left and right directions, the inner ends of the I-beams 8 on two adjacent vehicle chassis 3 are connected into a straight-line structure through a connecting mechanism. During use, the vehicle chassis 3 can walk between the roadways through the wheels. At this time, the I-beam 8 is arranged in the front and rear directions. Therefore, it can be ensured that the I-beam 8 will not interfere with the shelf 1 and the battery pack 2 when the vehicle chassis 3 walks in the front and rear directions of the roadway. After walking in place, the slide seat driving mechanism drives the lifting slide seat 5 to slide up along the guide rod 6, so that the I-beam 8 moves above the battery pack 2 on the shelf 1. The slewing mechanism drives the I-beam 8 to rotate to be horizontally arranged in the left and right directions. After the I-beams 8 of two adjacent vehicle chassis 3 that rotate to the left and right directions are connected into a straight-line structure through the connecting mechanism, a portal structure is formed as a whole. The electric hoist 10 can walk left and right on the connected I-beams 8. After walking in place, the electric hoist 10 lifts the battery pack 2 on the shelf 1. Then the vehicle chassis 3 walks. After moving in place, the electric hoist 10 places the battery pack 2 at the required position, realizing the transfer of the battery pack 2.

[0028] After the battery pack 2 is transported in reverse, the two I-beams 8 are disconnected, the slewing mechanism drives the I-beam 8 to rotate to the front and rear direction, and the slide drive mechanism drives the lifting slide 5 to slide downward along the guide rod 6. At this time, the entire device returns to the initial state, and the vehicle chassis 3 can travel to the next workstation in the lane again.

[0029] In one embodiment of the utility model, the wheel is an AGV driving wheel 4. The AGV driving wheel 4 not only provides power for walking, but also provides steering, which facilitates the travel and turning of the chassis 3.

[0030] In one embodiment of the utility model, a counterweight 14 is installed at the lower end of the chassis 3. The counterweight 14 can improve the stability of the chassis 3 and prevent the chassis 3 from overturning due to the eccentric load when the electric hoist 3 lifts the battery pack 2.

[0031] In one embodiment of the utility model, the slide drive mechanism can be the following structure, which includes oil cylinders Ⅰ 7 respectively arranged at the left and right ends of the guide rod 6, the axis of the oil cylinder Ⅰ 7 is arranged in the vertical direction, the bottom of the oil cylinder Ⅰ 7 is hingedly mounted on the vehicle chassis 3, and the head end of its piston rod is hingedly mounted on the lifting slide 5. The piston rod of the oil cylinder Ⅰ 7 extends outward, and it drives the lifting slide 5 to slide upward along the guide rod 6. The piston rod of the oil cylinder Ⅰ 7 retracts inward, and it drives the lifting slide 5 to slide downward along the guide rod 6. Since the oil cylinders Ⅰ 7 are arranged at both the left and right ends of the guide rod 6, the simultaneous operation of the two oil cylinders can improve the stability of the driving of the lifting slide 5.

[0032] In one embodiment of the utility model, the slewing mechanism includes a fence-type slewing drive reducer 11 installed on the support arm 12, the output shaft of the fence-type slewing drive reducer 11 is arranged in the vertical direction, the output shaft of the motor 19 is coaxially connected to the input shaft of the fence-type slewing drive reducer 11, and the I-beam 8 is connected to the output shaft of the fence-type slewing drive reducer 11. The motor 19 drives the I-beam 8 to rotate after the torque is decelerated and amplified by the fence-type slewing drive reducer 11, so that the I-beam 8 can be horizontally rotated in the front-to-back direction and the left-to-right direction, with a simple structure and reliable operation.

[0033] In one embodiment of the utility model, the connection mechanism includes a positioning seat 17 installed above the inner end of the I-beam 8, and a pin hole is horizontally arranged in the positioning seat 17. When the I-beams 8 on two adjacent vehicle chassis 3 are arranged in a straight line in the left and right directions, the two pin holes are coaxial, and the positioning pins 18 are inserted into the two pin holes. By inserting the positioning pins 18, the two I-beams 8 are ensured to be connected as a whole to prevent them from rotating freely, so that the electric hoist 10 can travel on the two I-beams 8.

[0034] After the two I-beams 8 are rotated into place, there may be a situation where their inner ends do not touch. At this time, the two I-beams 8 cannot be connected using the connecting mechanism. Therefore, in an embodiment of the present utility model, it further includes a sliding seat 13 installed on the output shaft of the fence-type slewing drive reducer 11. Chute grooves are respectively provided at the left and right ends of the sliding seat 13. The flange parts on the left and right sides of the upper end of the I-beam 8 are slidably installed in the corresponding chute grooves on the same side. It further includes a cylinder II 9. The axis of the cylinder II 9 is parallel to the I-beam 8. An ear seat I 15 is installed on the sliding seat 13. The tail end of the cylinder II 9 is hingedly installed on the ear seat I 15. An ear seat II 16 is installed on the I-beam 8. The piston rod head end of the cylinder II 9 is hingedly installed on the ear seat II 16. After the two I-beams 8 are rotated into place, the cylinder II 9 acts. It can push the I-beam 8 to slide left and right along the sliding seat 13, and finally adjust until the positioning seats 17 at the inner ends of the two I-beams 8 are in contact, which is convenient for connection using the positioning pin 18.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
