[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0039] like Figures 1 to 5As shown, an embodiment of the utility model provides an auxiliary replacement device, which includes a base 10, a connecting assembly 20 and an enclosure assembly 30. The base 10 is used to support the component 100. The connecting assembly 20 is used to be arranged on the side of the base 10 away from the component 100. The connecting assembly 20 is connected to the transport device 200. The enclosure assembly 30 is arranged on the base 10, and the enclosure assembly 30 is surrounded by the outer periphery of the base 10. The enclosure assembly 30 includes a first side plate 31 and a second side plate 32, and there is an angle between the first side plate 31 and the second side plate 32. The first side plate 31 has a relatively arranged avoidance position and an enclosure position. When the first side plate 31 is in the avoidance position, the first side plate 31 can avoid the base 10, and the first side plate 31 can move between the avoidance position and the enclosure position. The second side plate 32 is detachably arranged on the first side plate 31.

[0040] By applying the technical solution of the present application, the component 100 is placed on the base 10, the transport device 200 is connected to the connecting assembly 20, the enclosure assembly 30 is enclosed at the periphery of the component 100, and the first side plate 31 has an avoidance position and an enclosure position, and the second side plate 32 is detachably arranged on the first side plate 31. In this arrangement, during the use of the auxiliary replacement device, the enclosure assembly 30 needs to be disassembled first so as to move the component 100 to the base 10; then the enclosure assembly 30 is reassembled so as to enclose the component 100 to prevent the component 100 from falling from the base 10; then the transport device 200 is connected to the connecting assembly 20 to move the auxiliary replacement device and the component 100 to the desired position; the enclosure assembly 30 is disassembled again to move the component 100 from the base 10 to the desired position; and then the enclosure assembly 30 is reassembled. When disassembling the enclosure assembly 30, the staff can only disassemble the second side plate 32, or disassemble the second side plate 32 while moving the first side plate 31 to the avoidance position. Accordingly, when assembling the enclosure assembly 30, the staff installs the second side plate 32 on the first side plate 31, or installs the second side plate 32 on the first side plate 31 after moving the first side plate 31 to the enclosure position. With such a configuration, the staff can make independent choices according to needs, and the component 100 can be moved to the base 10 or removed from the base 10 from different angles, thereby improving the versatility of the auxiliary replacement device and facilitating the replacement of the component 100. In addition, with the above structure, when the staff moves the component 100 to the base 10 or removes it from the base 10, they only need to push the component 100, thereby reducing the labor intensity of the staff, further facilitating the replacement of the component 100, and eliminating the need for the staff to manually carry the component 100 during the climbing operation, thereby improving the safety of the operation and preventing the staff from being injured.

[0041] Optionally, when the staff uses the auxiliary replacement device, they can remove the component 100 from the frame 300, or place the component 100 on the frame 300, or remove the component 100 from the frame 300 and then place a new or repaired component 100 on the frame 300.

[0042] Furthermore, in the prior art, during the replacement process of some components 100, a replacement device with telescopic parts such as a telescopic oil cylinder is used for replacement. However, if the replacement device is capable of replacing components 100 at a high position, the structure of the telescopic parts needs to be greatly enlarged, which results in an increase in the volume of the replacement device. With such a configuration, the movement of the replacement device is difficult, which results in the inconvenience of using the replacement device. However, the auxiliary replacement device in the present application can be coordinated with a handling device 200 such as a hand forklift, which is easy to operate and convenient for moving the auxiliary replacement device, thereby facilitating the replacement of components 100. Optionally, the handling device 200 can also be an oil fork, an electric fork or other device, which the staff can choose independently according to their needs, and the lifting weight and lifting height can be selected according to the usage scenario.

[0043] Optionally, the frame 300 may be a battery rack, and the component 100 may be a battery pack. A plurality of battery packs are placed on the battery rack. This arrangement facilitates workers to replace battery packs at high places, thereby reducing the labor intensity of the workers.

[0044] like Figure 1 As shown, the X direction is the width direction of the base 10 , the Y direction is the length direction of the base 10 , and the Z direction is the vertical direction. The first side plate 31 can move relative to the base 10 along the vertical direction.

[0045] The enclosure assembly 30 includes two first side panels 31 and two second side panels 32. The two first side panels 31 are arranged at intervals on both sides of the base 10 along the width direction of the base 10. The first side panels 31 extend along the extension direction of the base 10. The two second side panels 32 are arranged at intervals on both ends of the base 10 along the extension direction of the base 10. The second side panels 32 extend along the width direction of the base 10. The two ends of the second side panels 32 are respectively detachably arranged on the two first side panels 31. The two first side panels 31 both have a relatively arranged avoidance position and an enclosure position. The two second side panels 32 can be detachably arranged on the two first side panels 31. Such an arrangement facilitates the assembly of the enclosure assembly 30, and further facilitates the staff to push the component 100 onto the base 10 or remove it from the base 10, further increasing the use range of the auxiliary replacement device, and further reducing the labor intensity of the staff.

[0046] like Figure 2As shown, the first side plate 31 is provided with a slot 311 extending in the vertical direction, and the second side plate 32 is movably arranged in the slot 311. Such a configuration has a simple structure, is convenient for processing the first side plate 31, and is convenient for disassembling and installing the second side plate 32, reducing the difficulty of assembly and installation for the staff.

[0047] Furthermore, a first limiting structure and a second limiting structure are provided between the first side plate 31 and the second side plate 32, wherein the first limiting structure can limit the displacement of the second side plate 32 in the vertical direction, and the second limiting structure can limit the displacement of the second side plate 32 in the width direction of the base 10. This arrangement can prevent the second side plate 32 from falling off the first side plate 31 during the operation of the auxiliary replacement device, thereby ensuring the stability of the enclosure assembly 30 and the enclosure effect of the enclosure assembly 30.

[0048] like Figure 3 As shown, the top of the second side plate 32 has a bent portion 321, which can abut against the top of the first side plate 31, and the bent portion 321 forms a first limiting structure. This arrangement facilitates processing of the second side plate 32, and facilitates disassembly and assembly of the second side plate 32 while ensuring the limiting of the second side plate 32 in the vertical direction.

[0049] Specifically, in the present application, the bent portion 321 of the second side plate 32 is bent in a direction away from the other second side plate 32 . Such a configuration can avoid interference between the bent portion 321 and the component 100 .

[0050] The bottom of the second side plate 32 is provided with a slot 322, which abuts against the side wall of the first side plate 31, and the slot 322 forms a second limiting structure. This arrangement is simple in structure, convenient for processing the second side plate 32, and can ensure the limiting effect of the second side plate 32.

[0051] Furthermore, in the present application, two card slots 322 are provided at the bottom of the second side panel 32, and the two card slots 322 are respectively provided at both ends of the second side panel 32, and the two card slots 322 are provided in one-to-one correspondence with the two first side panels 31, and the card slots 322 abut against the side walls of the corresponding first side panels 31 to prevent the second side panel 32 from shaking, thereby ensuring the working stability of the second side panel 32.

In this way, when the fastener 41 slides in the slide groove 312, the first side plate 31 can be moved between the avoidance position and the enclosure position, which has a simple structure and is easy to operate, and is convenient for processing the first side plate 31.

[0053] In the present application, the fastener 41 is a plum-shaped hand-tightened bolt, and the fastener 41 is threadedly connected to the base 10 . The fastener 41 can fix the first side plate 31 on the base 10 .

[0054] Specifically, the slide groove 312 includes a vertical section 3121 and a bending section 3122 connected to each other. The vertical section 3121 extends in the vertical direction. The bending section 3122 and the vertical section 3121 have an angle. The bending section 3122 cooperates with the fastener 41 to limit the displacement of the first side plate 31 in the vertical direction. With such an arrangement, the fastener 41 can enable the first side plate 31 to move between the avoidance position and the enclosure position during the sliding process of the vertical section 3121. Moreover, when the fastener 41 is located at the bending section 3122, the first side plate 31 is located at the enclosure position. With such an arrangement, the first side plate 31 can be prevented from being displaced in the vertical direction due to factors such as vibration when it is in the enclosure position, thereby ensuring the stability of the first side plate 31 when it is in the enclosure position.

[0055] Further, the connection assembly 20 includes a plurality of connection structures 21, the connection structures 21 extend along the extension direction of the base 10, the plurality of connection structures 21 are arranged at intervals along the width direction of the base 10, and the connection structures 21 have through holes, which are used to connect with the handling device 200.
