The guide sleeve 520 can be arranged on the end wall 311 of the counterweight block 310, or arranged on the side wall 312 facing the frame 100 or the side wall 312 away from the frame 100. Figure 3 The counterweight block 310 shown in the figure has an end wall 311 and a side wall 312 at the end, and the guide sleeve 520 can be arranged on the end wall 311 or the side wall 312 facing the frame 100 or the side wall 312 away from the frame 100.

By connecting the connecting pipe body 521 with the wall of the end of the counterweight mechanism 300, and by arranging the bushing 522 in the connecting pipe body 521 and sleeving the bushing 522 on the guide rod 510, the movement between the guide sleeve 520 and the guide rod 510 can be facilitated, and after wear, the guide sleeve 520 can be reused by replacing the bushing 522, and the bushing 522 is more convenient to disassemble and replace.

[0062] As shown in Figure 3 and Figure 4 , the connecting pipe body 521 is a hollow pipe body, the outer wall of the connecting pipe body 521 is welded and fixed with the end wall 311 of the counterweight mechanism 300, and the length of the connecting pipe body 521 is preferably consistent with the height of the counterweight mechanism 300, so as to increase the connection area of the connecting pipe body 521 and the counterweight mechanism 300 and improve the reliability of the connection with the counterweight mechanism 300. The length of the bushing 522 is shorter than the length of the connecting pipe body 521, and preferably, bushings 522 are installed at the upper and lower ends of the connecting pipe body 521 respectively, so as to be sleeved on the guide rod 510 at multiple positions and improve the guiding effect. The bushing 522 preferably adopts a copper sleeve. The fasteners pass through the bushing 522 from the outer wall of the connecting pipe body 521, so as to fixedly connect the bushing 522 with the connecting pipe body 521. In addition, multiple fasteners can be arranged in the circumferential direction of the connecting pipe body 521, so as to improve the reliability of the connection.

[0063] As shown in Figure 1 and Figure 2 , the counterweight mechanism 300 comprises a counterweight block 310, the connecting assembly comprises a chain 410 and a sprocket 420, the sprocket 420 is installed on the top of the frame body 100, one end of the chain 410 is connected with the counterweight block 310 and extends upward, is arranged around the sprocket 420 and then extends downward, until the other end of the chain 410 is connected with the battery taking and placing mechanism 200; the guide sleeve 520 is connected with the end wall 311 of the counterweight block 310, and the connection position of the chain 410 and the counterweight block 310 is close to the end of the counterweight block 310. By adopting the above structure of the counterweight mechanism 300 and the arrangement, the counterweight block 310 can be connected with the battery taking and placing mechanism 200 through the chain 410 and guided through the sprocket 420, so as to balance the lifting movement of the battery taking and placing mechanism 200. The connection position of the chain 410 and the counterweight block 310 is close to the edge position of the end of the counterweight block 310, so as to make the movement of the counterweight block 310 more stable.

[0071] As shown in Figure 5 , the sprocket 420 of the counterweight mechanism 300 is connected with the top plate. The top plate can also serve as a mounting component of the sprocket 420 of the counterweight mechanism 300, thereby facilitating the installation and arrangement of the sprocket 420. Specifically, as shown in Figure 5 and Figure 6 , the sprocket 420 is connected with the top plate through a sprocket mounting piece 700, the sprocket mounting piece 700 extends downwardly through the top plate. Thus, the sprocket 420 can be installed below the top plate.

[0072] As shown in Figure 5 and Figure 6 , the sprocket mounting piece 700 includes a pressing plate 720 and two connecting plates 710, each of the connecting plates 710 is in an inverted L shape and extends through the top plate, and the two connecting plates 710 are arranged at intervals and form a space for mounting the sprocket 420; the pressing plate 720 is fixedly connected with the top plate through fasteners on the upper side of the top plate.

Compared with the top plate and the bottom plate in the form of a whole plate, the plate body in the form of a split body can save materials and cost, reduce processing precision, facilitate processing and manufacturing, and be more stable after connection and not easily warped.

[0075] Specifically, when the bottom plate is a whole plate, it is easy to cause instability and partial places to be easily warped, and if a certain flatness is to be met, the corresponding processing precision requirement will be relatively high; at the same time, the whole bottom plate is connected with the bottom of the container and the four columns 110 at the same time, so a high precision is required when connecting and installing.
