Specific implementation

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the skilled in the art without creative labor belong to the protection scope of the utility model.

[0041] The embodiments of the utility model will be described below in combination with Figures 1 to 7 .

[0042] According to the embodiment of the utility model, on the one hand, a kind of energy storage battery box auxiliary replacement device is provided, it includes: tow pushing component 1 and lifting transfer component 2.Tow pushing component 1 includes: article table 11, tow device 12 and drive mechanism 13, drive mechanism 13 is set to the article table 11, the drive end of drive mechanism 13 is connected with one end of tow device 12, the other end of tow device 12 is suitable for connecting energy storage battery box, drive mechanism 13 is suitable for driving tow device 12 and energy storage battery box move along the length direction of article table 11.Lifting transfer component 2 includes: mobile base 21 and lifting mechanism 22, lifting mechanism 22 is set to mobile base 21, the drive end of lifting mechanism 22 is connected with article table 11, and lifting mechanism 22 is suitable for driving tow pushing component 1 to lift along the height direction of article table 11.

[0043] The setting of mobile base 21 enables the auxiliary replacement device to move flexibly and change working position, specifically, the mobile base 21 in the embodiment includes a rectangular base and wheels arranged at four corners of the base.Lifting mechanism 22 is arranged on the base, which can drive the whole tow pushing component 1 to lift and change working height to meet the replacement needs of energy storage battery boxes at different heights.Article table 11 in tow pushing component 1 can be a steel platform, one end of which is connected with the drive end of lifting mechanism 22, and the other end is close to the energy storage battery box during work.Drive mechanism 13 can provide driving force for tow device 12 to drive it to move linearly, and when tow device 12 is connected with the energy storage battery box, drive mechanism 13 can drive tow device 12 to pull the energy storage battery box from the cabinet to article table 11, and then disassemble and repair, or send the repaired energy storage battery box back to the cabinet.Furthermore, to adapt to the work needs, drive mechanism 13 is generally arranged at the end of article table 11 far from the energy storage battery box, so that tow device 12 is closer to the energy storage battery box, which is more convenient for connection, and has a larger pulling stroke, which can directly pull the energy storage battery box to article table 11.

[0044] The energy storage battery box auxiliary replacement device has the functions of moving, lifting and pulling, which can meet the needs of the replacement process of energy storage battery box. Workers can perform replacement work by operating each mechanism, which improves the automation degree of replacement work, thereby saving labor and time costs and improving work efficiency. At the same time, workers do not need to perform a large amount of manual work at a high place, which is safer.

[0045] In one embodiment, a plurality of rollers 111 are arranged on article table 11.

[0046] Exemplarily, as Figure 7As shown, six grooves are formed on the storage table 11, and the six grooves are arranged in two rows and three columns. Four supporting rollers 111 are arranged in each groove. The supporting rollers 111 can be made of nylon with good wear resistance, and the surface of the supporting rollers 111 is higher than the top surface of the groove. In this way, when the traction device 12 pulls the energy storage battery box to move, the rotation of the supporting rollers 111 can effectively reduce the friction, facilitate the movement of the energy storage battery box, and also avoid abrasion to the energy storage battery box.

[0047] The arrangement of the supporting rollers 111 in this embodiment is only an example, and the present embodiment does not limit the arrangement position, arrangement manner and arrangement number of the supporting rollers 111. In other embodiments, the size of the storage table 11 and the size of the energy storage battery box can be reasonably adjusted.

[0048] In other embodiments, the supporting rollers 111 can not be arranged, and the upper surface of the storage table 11 can be processed into a smooth surface with small roughness, which can also achieve the above-mentioned effect of reducing friction.

[0049] In an embodiment, the storage table 11 is provided with a baffle 112 on each side.

[0050] The baffle 112 can also be made of a steel plate and directly welded with the storage table 11. The length of the baffle 112 can be equal to or less than the length of the storage table 11. For example, Figure 7 As shown, the baffle 112 is arranged at the middle position of the storage table 11, and the length of the baffle 112 is less than the length of the storage table 11.

[0051] The arrangement of the baffle 112 can protect the energy storage battery box from falling from the storage table 11 when the traction device 12 pulls the energy storage battery box to move.

[0052] Further, the baffle 112 can also be a grid-shaped plate, i.e. a plate with holes or a grid. In this way, the material can be reduced and the weight can be reduced.

[0053] In an embodiment, the traction and pushing assembly 1 further comprises a telescopic support rod 14, which is arranged at the end of the storage table 11 away from the connection with the lifting mechanism 22, and the telescopic support rod 14 can be telescoped along the height direction of the storage table 11.

[0054] Specifically, the telescopic support rod 14 can be an electric telescopic rod, the fixed end of which is connected with the ground of the storage table 11, and the driving end thereof can be provided with a support plate to increase the support area. When the storage table 11 is lifted to an appropriate working height, the telescopic support rod 14 is extended to support on the ground, so that both ends of the storage table 11 can be stably supported, preventing the end of the storage table 11 from being deformed by the energy storage battery box.

[0055] In one embodiment, the traction device 12 comprises a rod body 121 and a connecting head 122, one end of the rod body 121 is connected with the driving end of the driving mechanism 13, and the other end is provided with the connecting head 122, and a plurality of connecting holes are arranged on the connecting head 122 in the circumferential direction.

[0056] As shown in Figure 7 , the rod body 121 is a circular rod, and the axial direction is parallel to the length direction of the storage table 11. A plurality of through holes are arranged on the connecting head 122 in the circumferential direction. By aligning the through holes with the positioning holes on the energy storage battery box and connecting them by bolts, the connection of the traction device 12 and the energy storage battery box is completed. The driving mechanism 13 applies a driving force from one end of the rod body 121 away from the connecting head 122, so as to drive the energy storage battery box to move.

[0057] In one embodiment, the driving mechanism 13 comprises a driving motor 131 and a crank linkage mechanism 132, one end of the crank linkage mechanism 132 is connected with the driving motor 131, and the other end is connected with one end of the rod body 121.

[0058] The driving motor 131 is fixedly arranged on the storage table 11. The crank linkage mechanism 132 comprises a first connecting rod 1322 and a second connecting rod 1323, one end of the first connecting rod 1322 is connected with the output shaft of the driving motor 131 through a synchronous pulley 1321, one end of the second connecting rod 1323 is connected with the other end of the first connecting rod 1322 through the synchronous pulley 1321, and the other end of the second connecting rod 1323 is connected with one end of the traction device 12 (i.e. one end of the rod body 121 away from the connecting head 122) through the synchronous pulley 1321. When the driving motor 131 starts to drive the first connecting rod 1322 to rotate, the second connecting rod 1323 is driven to reciprocate the traction device 12. When the first connecting rod 1322 is parallel to the traction device 12 and located on the side of the driving motor 131 close to the energy storage battery box, the traction device 12 reaches the farthest position (the warehouse entry position), which can send the energy storage battery box back to the cabinet; when the first connecting rod 1322 is parallel to the traction device 12 and located on the side of the driving motor 131 away from the energy storage battery box, the traction device 12 reaches the nearest position (the warehouse exit position), which can pull the energy storage battery box to the storage table 11.

[0059] In addition, a limiting sleeve 1324 is arranged on the storage table 11, and the traction device 12 reciprocates in the limiting sleeve 1324, and the limiting sleeve 1324 plays a role of limiting and guiding.

[0060] In one embodiment, the storage table 11 is provided with a detection device 113, and the detection device 113 is used for detecting the position information of the traction device 12.

[0061] Specifically, the detection device 113 in the embodiment is a limit switch, which can be arranged on the storage table 11 and correspond to the farthest position (warehousing position) and the closest position (warehousing-out position) of the traction device 12. The limit switch can be electrically connected with the driving motor 131, and the driving motor 131 can be controlled to be turned off when the limit switch detects that the traction device 12 reaches the corresponding position.

[0062] In another embodiment, the limit switch corresponding to the farthest position (warehousing position) can be arranged on the cabinet door.

[0063] In an embodiment, the lifting mechanism 22 comprises a hydraulic driving device 221, two chain wheels 222 and two transmission chains 223. The mounting end of the hydraulic driving device 221 is arranged on the moving base 21, and the driving end of the hydraulic driving device 221 is provided with a connecting shaft 224. The two ends of the connecting shaft 224 are respectively provided with two chain wheels 222. One end of each transmission chain 223 is connected with the moving base 21, and the other end of each transmission chain 223 passes around one chain wheel 222 and is connected to the storage table 11.

[0064] Specifically, the hydraulic driving device 221 comprises a hydraulic operating rod 2211 and a hydraulic oil cylinder 2212 connected with each other. The piston rod of the hydraulic oil cylinder 2212 can be lifted by adjusting the operating piston rod. When the piston rod needs to be lowered, the pressure relief valve 2213 on the hydraulic oil cylinder 2212 can be opened. The hydraulic operating rod 2211 can also serve as a push rod to move the moving base 21.

[0065] The end of the driving end of the hydraulic driving device 221, i.e., the end of the piston rod, is provided with the connecting shaft 224, and the axial direction of the connecting shaft 224 is perpendicular to the axial direction of the piston rod. The two ends of the connecting shaft 224 are respectively provided with the chain wheels 222, which can be engaged with the transmission chains 223. One end of each transmission chain 223 is fixedly connected with the moving base 21, and the other end of each transmission chain 223 passes around the chain wheel 222 from above and is connected to the storage table 11. The two chain wheels 222 and the two transmission chains 223 symmetrically arranged on both sides of the hydraulic oil cylinder 2212 can ensure that the storage table 11 is subjected to force on both sides and is lifted more stably.

[0066] In other embodiments, the lifting mechanism 22 can also be other mechanisms capable of realizing linear movement, such as an electric telescopic rod arranged at the bottom of the storage table 11.

[0067] In an embodiment, the lifting and transferring assembly 2 further comprises a frame 23, and the frame 23 is provided with the insertion holes 231 at both sides thereof. The insertion holes 231 are provided with the insertion pins 232, and the two ends of the connecting shaft 224 are further provided with the hooks 225, which are adapted to be hooked to the insertion pins 232.

[0068] The frame 23 is a rectangular frame that stands upright on the movable base 21. Multiple insertion holes 231 are spaced apart from top to bottom on both sides of the frame 23, with the insertion holes 231 on both sides corresponding to each other. Pins 232 can be installed inside the insertion holes 231. The two ends of the connecting shaft 224 can extend from the sprocket 222 and are equipped with hooks 225. Thus, when the platform 11 is raised to a suitable working position, the hooks 225 can be hooked onto the pins 232 before pulling the energy storage battery box, preventing the platform 11 and the energy storage battery box from falling due to insufficient pressure or sudden pressure release caused by a malfunction of the hydraulic cylinder 2212. The insertion holes 231 at different heights on both sides of the frame 23 correspond to the energy storage battery boxes at different heights.

[0069] In one embodiment, the lifting and transfer assembly 2 further includes a plurality of support legs 24 disposed on the movable base 21.

[0070] like Figure 1 As shown, support legs 24 are provided on the left, right, and rear sides of the movable base 21. Specifically, the support legs 24 include an L-shaped connecting square tube and an L-shaped supporting square tube. The L-shaped connecting square tube is disposed on the movable base 21 and is hollow inside. One end of the L-shaped supporting square tube is inserted into the L-shaped connecting square tube, and the other end is supported on the ground.

[0071] Once the auxiliary replacement device reaches the working position, the L-shaped support square tube can be connected to the L-shaped connecting square tube to support the auxiliary replacement device, ensuring that the auxiliary replacement device can work stably and preventing the wheels from contacting the ground during operation and causing positional movement that could lead to an accident.

[0072] The usage process of the energy storage battery box auxiliary replacement device provided in this embodiment is described below:

[0073] The area around the prefabricated energy storage battery compartment is typically paved with gravel. Iron plates can be laid on the gravel path to facilitate the movement of the replacement device. After pushing the replacement device to the corresponding cabinet door of the energy storage battery box to be replaced, connect the L-shaped support tube to the L-shaped connecting tube to support the replacement device, separating the wheels from the ground. Then, adjust the hydraulic operating lever 2211 to drive the hydraulic cylinder 2212 to rise, simultaneously raising the platform 11 to a suitable working height via the sprocket 222 and transmission chain 223. Finally, hook 225 onto the pin 232.

[0074] After that, the work of pulling the energy storage battery box can be carried out, the driving motor 131 is started to drive the crank connecting rod mechanism 132 to work, and then drive the traction device 12 to move to the cabinet door, and then connect the traction device 12 with the energy storage battery box. Then the energy storage battery box is gradually pulled to the storage table 11, when the detection device 113 (limit switch) detects that the traction device 12 reaches the nearest position (out of the warehouse), the driving motor 131 is closed. When the energy storage battery box is sent back to the cabinet after maintenance, the driving motor 131 needs to be started again, the traction device 12 pushes the traction device 12 into the cabinet, when the detection device 113 (another limit switch) detects that the traction device 12 reaches the farthest position (into the warehouse), the driving motor 131 is closed again. After separating the traction device 12 from the energy storage battery box, the storage table 11 can be lowered, and when the storage table 11 is lowered, the pressure relief valve 2213 needs to be opened, and the storage table 11 and the energy storage battery box are freely lowered by releasing part of the pressure. Then the auxiliary replacement device can be transferred to other working positions.

[0075] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
